Abstract

A foldable golf trolley 10 comprising a frame 16, and a base 12 including a plurality of wheels 14. The base may include a first 18 and second 20 base segments, each including a wheel. The trolley may include a handle bar (figures 11-12), and it may be an electric golf trolley including a battery. During a transition between a deployed configuration (fig. 1) and a collapsed configuration (fig. 3), at least part of the frame moves relative to the base, and the first and second base segments may also move relative to each other. The frame 16 and first base segment 18 move interdependently, in unison, move synchronously, e.g. due to connecting members (28, 32; see figs. 4-8). Also claimed is a height adjustment mechanism for the golf trolley, configured such that an adjusted height of a handle is repeatedly automatically reached when transitioning into deployed configuration. This may include a spring-biased pin (60; fig. 13) able to engage with first and second locking slots (62, 64; fig. 13) in the respective configurations, with the relative locations of the slots being adjustable to set the height.

Description

Foldable Golf Trolleys

Field

[1] The present invention relates to foldable electric golf trolleys and height adjustable foldable electric golf trolleys.

Background

[2] Foldable electric golf trolleys are those electric golf trolleys which may be reversibly deployed from a collapsed configuration prior to use, and collapsed again for storage or transportation.

[3] Typically, foldable electric golf trolleys include several foldable regions in order that they are as compact as possible when in a collapsed configuration. Foldable electric golf trolleys are typically much more complex in design then non-electric trolleys because they are more cumbersome given their battery (which often remains in situ when the trolley is collapsed) and their powerable components. Thus, folding mechanisms of foldable electric golf trolleys are typically quite different to those of foldable non-electric, e.g. push, golf trolleys.

[4] Golfers desire ever more compact foldable electric golf trolleys so that they may easily fit into the boot of a car, for example, together with a golf club bag. However, importantly, golfers also require foldable electric golf trolleys which are easier to use and quicker to deploy and collapse. This desire is shared by golf equipment producers and retailers in order to reduce the barrier to entry to the sport for potential new golfers.

[005] There is thus an ongoing need to improve the ease of use of foldable electric golf trolleys. The present invention aims to address these and other problems with the prior art.

Summary

[6] Accordingly, in a first aspect, the present invention provides a foldable electric golf trolley comprising a battery; one or more powerable components (e.g. an electric motor); a frame, and a base including a plurality of wheels.

[7] The foldable electric golf trolley is configured to transition between a deployed configuration and a collapsed configuration. Generally, the deployed configuration is an arrangement in which the golf trolley is driveable about a golf course. Generally, the collapsed configuration is an arrangement in which the golf trolley is in a storable, typically non-driveable, state.

[8] During a transition between the deployed configuration and the collapsed configuration, at least part of the frame moves relative to the base and a first base segment including a said wheel moves relative to a second base segment including at least one other said wheel.

[9] During a transition from the deployed configuration towards the collapsed configuration movement of the frame and movement of the first base segment are substantially interdependent.

[10] Additionally, or alternatively, during a transition from the collapsed configuration towards the deployed configuration movement of the frame and movement of the first base segment are substantially interdependent.

[11] In other words, the first base segment and the frame are movably coupled to one another such that one may not move independently of the other. Generally, the first base segment and the frame are movably coupled to one another by a mechanical coupling means.

[12] The foldable electric golf trolley thus comprises a one-step folding mechanism: the mechanics for folding the frame relative to the second base segment and the mechanics for folding the first base segment relative to the second base segment are operably linked. Thus, a user needs only to make a single action to fold the electric golf trolley completely from the deployed configuration to the collapsed configuration and/or to unfold the electric golf trolley from the collapsed configuration to the deployed configuration [13] Conversely, in order that existing foldable electric golf trolleys are as compact as possible when in a collapsed configuration (for storage and/or transport), they conventionally include at least two operably distinct folding points: the golf trolley frame is usually foldable relative to the base of the golf trolley, and is often also foldable in half lengthwise; and, separately, a segment of the base, typically including a front wheel, is also foldable relative to the remainder of the golf trolley. This is due, in part, because of the difficulty in working around the bulky powerable components and battery located in the base.

[14] Where several parts of existing foldable electric golf trolleys are foldable, multiple manual operations, e.g. via the actuation of buttons, latches or levers, are required in order for existing electric golf trolleys to be fully folded to a collapsed configuration. The several parts are not operably linked, e.g. by a mechanical coupling means.

[015] For example, a known electric golf trolley may include a first mechanism for folding the frame relative to the base and a second mechanism for folding a segment of the base, including a front wheel of the trolley, relative to the remainder of the base.

[16] This is especially taxing for older or physically weaker players. In particular, it is desirable to provide a golf trolley which does not require a user to bend down to undertake a manual operation for folding or unfolding.

[17] Where only a single operation is required, for example in a Motocaddy (RTM) '6-Series' electric golf trolley, only the golf trolley frame is foldable (i.e. no part of the base or wheels of the trolley fold relative to the remainder of the trolley between deployed and collapsed configurations). Therefore, the foldable electric golf trolley is less compact when stored.

[18] Therefore, there remains an ongoing need to reduce the size of the trolley when collapsed so it can be more easily stored, while minimising the manual operation burden for a user.

[19] The present invention provides a golf trolley which can be deployed and collapsed with the user remaining relatively upright, e.g. standing upright rather than bending over or crouching, throughout, compared with existing foldable golf trolleys, and which requires only a single folding and/or unfolding action.

[020] Generally, the frame is that part of the foldable electric golf trolley which extends substantially vertically from the base in the deployed configuration, and which is engaged by a user to control the operation of the golf trolley. For example, the frame may include a steering means in the form of a handlebar. The steering means may include one or more electronic components.

[21] Generally, the foldable electric golf trolley may include three wheels -two rear wheels driven by a motor, and a further, typically passive e.g. non-driven, wheel towards the front of the trolley. In embodiments, the foldable electric golf trolley may include more than three wheels, e.g. four wheels. Typically, the first base segment (including a non-driven wheel) may fold substantially underneath the second base segment during a transition from the deployed configuration to the collapsed configuration.

[22] In embodiments, movement of the frame and movement of the first base segment are substantially interdependent during both a transition from the deployed configuration towards the collapsed configuration and a transition from the collapsed configuration towards the deployed configuration.

[23] In embodiments, the frame and the first base segment may be hingedly connected to the second base segment towards substantially opposing ends thereof. In other words, the first base segment may be a forward-most base segment, typically including a non-driven wheel and the frame may be hingedly connected to an opposing end of the second base segment. The second base segment may include two driven wheels located in either side thereof.

[24] In embodiments, during a transition from the deployed configuration towards the collapsed configuration, the second base segment may rotate relative to a wheel thereof with the wheel remaining substantially static, on the ground, during said s transition.

[25] Therefore, a user may more straightforwardly transition the foldable electric golf trolley from the deployed configuration towards the collapsed configuration as the second base segment (which is usually the segment including the bulky battery and motor) rotates about the wheel(s) of that base segment. Usefully, a user may apply load to the hinged attachment between the frame and the second base segment (e.g. by pushing downwardly on the frame) in order to cause the second base segment to rotate relative to the wheel(s) of the second base segment. This is particularly advantageous compared to known electric golf trolleys which either include and require two stage folding mechanisms or include fewer foldable segments.

[26] Additionally, or alternatively, during a transition from the collapsed configuration towards the deployed configuration, the second base segment may rotate relative to a wheel thereof with the wheel remaining substantially static on the ground during said zo transition.

[27] In embodiments, the foldable electric golf trolley is substantially in the form of a first class lever. In other words, the fulcrum of the foldable electric golf trolley is located substantially between the load of the majority of the base and the force input by a user zs to transition the electric golf trolley between the collapsed and deployed configurations.

[28] In embodiments, the foldable electric golf trolley may be substantially biased towards the collapsed configuration. For example, the foldable electric golf trolley may include a number of springs which bias the first base segment and the frame in their direction of folding relative to the second base segment.

[29] In embodiments, the frame and the first base segment may be coupled to one another via one or more connecting members.

[30] In embodiments, the or each connecting member may be configured such that the frame and first base segment move substantially synchronously during a transition from the deployed configuration towards the collapsed configuration. Additionally, or alternatively, the or each connecting member may be configured such that the frame and first base segment move substantially synchronously during a transition from the collapsed configuration towards the deployed configuration.

[31] The interdependency of the movement of the frame and the movement of the 10 first base segment means that the frame may not move relative to the base unless the base segment also moves relative to the base, and vice versa.

[32] In embodiments, the or each connecting member may comprise a strut which extends substantially between the hinged attachments of each of the frame and base segment and the base. In embodiments, the foldable electric golf trolley may comprise two connecting members which flank the battery of the golf trolley. In other words, the battery of the foldable electric golf trolley may be located substantially in between two substantially parallel struts which connect the frame to the first base segment. In embodiments, the or each substantially rigid strut may be rotatably connected to the hinged attachments between each of the frame and first base segment and the second base segment. In embodiments, the hinged attachments between the frame and the first base segment may be geared in order to synchronise the interdependent movement thereof. For example, the hinged attachment between the frame and the second base segment may include a cam which is larger than a cam at the hinged attachment between the first base segment and the second base segment.

[33] In embodiments, the foldable electric golf trolley may be in a relatively locked state in at least one of the deployed and collapsed configurations, in which state the frame and first base segment may be substantially prevented from moving relative to the second base segment. In embodiments, the foldable electric golf trolley may be in a relatively unlocked state between the deployed and collapsed configurations, in which state the frame and first base segment may be substantially free to move relative to the second base segment. In embodiments, the foldable electric golf trolley may be in a relatively locked state in both the deployed and collapsed configurations [34] In embodiments, a transition from the collapsed configuration to the deployed configuration may be actuated via a single actuator, and/or a transition from the deployed configuration to the collapsed configuration may be actuated via a single actuator. In embodiments, a common single actuator may be configurated to actuate transitions from the collapsed configuration to the deployed configuration and vice versa.

[35] In embodiments, the single actuator may be configured to switch the foldable electric golf trolley from the locked state to the unlocked state in at least one of the deployed and collapsed configurations and, in embodiments, both the deployed and collapsed configurations.

[36] Therefore, switching the golf trolley from the locked state to the unlocked state, and thus a transition between the deployed configuration and the collapsed configuration, is prevented unless the single actuator is engaged by a user.

[37] In embodiments, the actuator may be configured to actuate both a switch from the locked state in the collapsed configuration to the unlocked state and from the locked state in the deployed configuration to the unlocked state. In other words, a transition from the locked state (in the collapsed configuration) to the unlocked state, to facilitate a transition from the collapsed configuration to the deployed configuration, and a transition from the locked state (in the deployed configuration) to the unlocked state, in order to facilitate a transition from the deployed configuration to the collapsed configuration, may be actuable by a common, i.e. shared, single actuator.

[38] In embodiments, separate actuators may be provided for switching the golf trolley from the locked state to the unlocked state when in the deployed and collapsed configurations. Thus, alternatively, separate actuators may be provided: a first actuator for transitioning the foldable electric golf trolley from the locked to the unlocked state when the trolley is in the collapsed configuration; and a second actuator for transitioning the foldable electric golf trolley from the locked to the unlocked state when the trolley is in the deployed configuration.

S

[039] In embodiments, the foldable electric golf trolley may be biased towards the locked state when the foldable electric golf trolley is in the collapsed configuration or the deployed configuration. In embodiments, the actuator may be configured to bias the foldable electric golf trolley towards the locked state and one or other of the collapsed configuration or deployed configuration. Therefore, in the absence of actuation via the actuator, the foldable electric golf trolley tends towards the locked state. For example, the foldable electric golf trolley may be biased by one or more springs towards the locked state.

[040] In embodiments, the actuator may comprise a user-engageable control, e.g. a switch, and one or more biased locking members which are operably connected to the user-engageable control. In embodiments, operation of the user-engageable control may move the or each locking member substantially against their direction of bias. In embodiments, the user-engageable control may comprise a lever. For example, pushing the lever against the bias of the locking members may transition the foldable electric golf trolley from the locked state to the unlocked state, allowing a transition to either the collapsed or deployed configuration.

[41] In embodiments, the or each locking member may be a spring-biased bar or pin.

[42] In embodiments, a said biased locking member may be located proximal a hinged attachment between the frame and the second base segment; and the biased locking member proximal the hinged attachment may have a first locking location when the foldable electric golf trolley is in the deployed configuration and a second locking location when the foldable electric golf trolley is in the collapsed configuration. In embodiments, the biased locking member proximal the hinged attachment may be a spring-biased bar.

[043] In embodiments, the frame may include a joint arranged such that the frame is foldable lengthwise. For example, the frame may be configured to fold in a concertinaed fashion. In another example, the frame may be configured to fold substantially telescopically.

[44] In embodiments, a said biased locking member may be located proximal said joint; and the biased locking member proximal the joint may have a first locking location when the foldable electric golf trolley is in the deployed configuration and a second locked location when the foldable electric golf trolley is in the collapsed configuration. For example, a said biased locking member may be located substantially within the said joint. In embodiments, the biased locking member proximal the joint may be a spring-biased pin.

[45] Thus, the actuator may include locking means at both a hinged attachment between the frame and the second base segment and between foldable segments of the frame. In user, operation of the user-engageable control may do two things: detach a locking member from a locking location at the joint; and detach a locking member from a locking location at the hinged attachment between the frame and the second base segment. These actions may take place substantially simultaneously.

[46] In embodiments, the user-engageable control may be located at the joint. The user-engageable control is therefore located at a convenient height for a user. In embodiments, the user-engageable control may be a manually operable lever or the like. For example, the user-engageable control may be a button. In embodiments, the user-engageable control may be electronic, e.g. a touch-button. In embodiments, the user-engageable control may be a receiver configured to receive a signal from a transmitter.

[47] In embodiments, the foldable electric golf trolley may include height adjustment means for adjusting the height of a steering means of the foldable electric golf trolley in the deployed configuration. Generally, the steering means may form part of the frame. In other words, the height adjustment means is substantially wholly integrated with the foldable golf trolley [048] In embodiments, the height adjustment means may be configured such that an adjusted height of the steering means is repeatably automatically reached when the foldable electric golf trolley is transitioned from the collapsed configuration to the deployed configuration. In other words, a user need not readjust the height of the steering means each time the foldable electric golf trolley is transitioned to the deployed configuration. In embodiments, the height adjustment means may be operable substantially without the use of a separate tool. In other words, the height adjustment means may form an integral part of the foldable electric golf trolley, so that the height of the steering means may be adjusted on the fly, e.g. during a round of golf. Typically, the golf trolley may remain in a usable configuration during adjustment of the height of the steering means.

[49] In embodiments, the actuator and height adjustment means may be operably coupled. For example, part of the actuator may also form part of the height adjustment 10 means.

[50] In embodiments, part of the height adjustment means may be configured to be operably engaged by a said biased locking member. For example, a biased locking member may comprise a locking pin and the function of the height adjustment means may be dependent at least partially on an engagement, or lack thereof, with the locking pin.

[51] In embodiments, the height adjustment means may include a first locking slot for a said biased locking member in the collapsed configuration; and a second locking slot for the biased locking member in the deployed configuration. In embodiments, the location of the second locking slot relative to the first locking slot may be adjustable in order to adjust the height of the steering means when the foldable electric golf trolley is in the deployed configuration.

[052] In embodiments, the height adjustment means may have an adjusting setting in which the location of the second locking slot relative to the first locking slot may be adjusted, and a non-adjusting setting in which adjusting the location of the second locking slot relative to the first locking slot may be substantially prevented. In embodiments, the height adjustment means may be configured such that it can remain in the non-adjusting setting during a transition between the deployed and collapsed configurations. Therefore, an adjusted height of the steering means can be retained through folding and unfolding of the golf trolley.

[53] In embodiments, the height adjustment means may be configured to allow adjustment of the height of the steering means between around 50 cm and around 150 cm in height.

[54] In embodiments, the second base segment may comprise two driven wheels (i.e. wheels which are operably engaged by the drivetrain) and a trolley support surface may be located therebetween, the trolley support surface being configured to contact the ground when the foldable electric golf trolley is in the collapsed configuration. Generally, the two driven wheels may be located towards the rear of the electric golf trolley and a passive, non-driven wheel may be located towards the front of the electric golf trolley.

[55] In embodiments, the trolley support surface may be substantially perpendicular to the ground in the deployed configuration and substantially parallel to the ground in the collapsed configuration.

[56] In embodiments, the two driven wheels and the trolley support surface may together form a support structure in the collapsed configuration on which the foldable electric golf trolley can rest. In other words, the arrangement of the trolley support surface and two driven wheels may be such that each of the two driven wheels and the trolley support surface contact the ground when the foldable electric golf trolley is in the collapsed configuration. Thus, the foldable electric golf trolley may assume a 'standing' position whereby the trolley rests on the two rear, driven wheels and the trolley support surface in the collapsed configuration, rather than resting on all of the wheels of the trolley. In embodiments, in the standing position, a forwardmost, non-driven wheel may not be in contact with the ground. In other words, only the two driven wheels and the trolley support surface may be in contact with the ground in the collapsed configuration.

[057] In embodiments, the longitudinal axis of the frame in the collapsed configuration may be substantially parallel to the longitudinal axis of the frame in the deployed configuration.

[58] In a further aspect, the present invention provides a foldable golf trolley comprising a frame, and a base including a plurality of wheels. The foldable golf trolley is configured to transition between a deployed configuration and a collapsed configuration. Generally, the deployed configuration is an arrangement in which the golf trolley is driveable about a golf course. Generally, the collapsed configuration is an arrangement in which the golf trolley is in a storable, typically non-driveable, state.

[59] During a transition between the deployed configuration and the collapsed configuration, at least part of the frame moves relative to the base and a first base segment including a said wheel moves relative to a second base segment including at least one other said wheel. During a transition from the deployed configuration towards the collapsed configuration movement of the frame and movement of the first base segment are substantially interdependent.

[060] Additionally, or alternatively, during a transition from the collapsed configuration towards the deployed configuration movement of the frame and movement of the first base segment are substantially interdependent.

[61] In other words, the foldable golf trolley may be a non-electric, e.g. push-type, golf trolley.

[62] In a further aspect, the present invention provides a foldable golf trolley comprising a frame including a steering means, and a base including a plurality of wheels; wherein the foldable golf trolley is configured to transition between a deployed configuration and a collapsed configuration. Typically, the golf trolley may be an electric golf trolley, but the golf trolley may be a non-electric, e.g. push-type, golf trolley.

[63] During a transition between the deployed configuration and the collapsed configuration, at least part of the frame moves relative to the base. The foldable golf trolley further comprises a height adjustment means for adjusting the height of the steering means in the deployed configuration; wherein the height adjustment means is configured such that an adjusted height of the steering means is repeatably automatically reached when the foldable electric golf trolley is transitioned from the collapsed configuration to the deployed configuration; and wherein the height adjustment means is substantially wholly integrated with the foldable golf trolley.

[64] There is an ongoing need to provide a golf trolley which is height adjustable but which retains it's adjusted height through repeated deployments, and which minimises the amount of additional manual effort required by a user during deployment and collapsing of the golf trolley. In existing golf trolleys, the height of a handlebar of the frame is generally either not adjustable at all, not adjustable without the use of separate tools, or must be adjusted every time the golf trolley is deployed. Therefore, several distinct mechanisms and thus separate manual operations are required before a golf trolley is fully deployed or collapsed. This is not the case with the present invention, which provides a foldable golf trolley including height adjustment means which can be set and left, e.g. forgotten about by the user; with the steering means being automatically repeatably deployed to an adjusted height without the need to readjust the height during each iteration of the trolley's deployment.

[65] The height of the steering means is therefore adjustable without the use of a separate tool. Although, it may be that in embodiments the height of the steering means may be adjustable with the use of a distinct tool, for example for users with impaired grip.

[66] Advantageously, the height adjustment means may be configured such that the height of the steering means may be adjusted without the removal or detachment of any part of the electric golf trolley. In other words, the golf trolley is configured to remain substantially whole throughout adjustment of the height of the steering means.

For example, a screw or other fixing may not need to be removed from the golf trolley (typically using a screwdriver or other separate tool) in order for the height of the steering means to be modified. In embodiments, the golf trolley may be configured to remain in a substantially usable configuration during adjustment of the height of the steering means.

[67] Generally, the height adjustment means forms part of a joint between segments of the frame of the foldable golf trolley. Thus, the angle between joined frame segments may be altered at the joint in order to adjust the height of the steering means.

[68] Advantageously, the height adjustment means may be configured such that the segments of the frame sit substantially parallel with one another in the collapsed configuration of the golf trolley irrespective of the height set for the steering means.

[69] In embodiments, during a transition between the deployed configuration and the collapsed configuration at least part of the frame may move relative to the base and a first base segment including a said wheel may move relative to a second base segment including at least one other said wheel; wherein during a transition from the deployed configuration towards the collapsed configuration and/or during a transition from the collapsed configuration towards the deployed configuration movement of the frame and movement of the first base segment may be substantially interdependent.

[70] In embodiments, the foldable golf trolley may comprise an actuator configured to actuate a transition from the collapsed configuration towards the deployed configuration and/or from the deployed configuration towards the collapsed configuration wherein the actuator includes a user-engageable control and one or more locking members which are operably connected to the user-engageable control. In embodiments, the height adjustment means is configured to be operably engaged by a said locking member.

[71] In embodiments, the actuator may form part of the height adjustment means.

[72] Additionally, or alternatively, the foldable golf trolley may comprise an actuator configured to facilitate a transition from the deployed configuration to the collapsed configuration; wherein the actuator includes a user-engageable control and one or more locking members which are operably connected to the user-engageable control; and wherein the height adjustment means is configured to be operably engaged by a said locking member. For example, the or each locking members may form part of the actuator and the height adjustment means.

[73] In embodiments, the locking member may comprise one or more locking pins.

[74] In embodiments, the height adjustment means may include a first locking slot for a said locking pin when in the collapsed configuration; and a second locking slot for the locking pin when in the deployed configuration. In embodiments, the location of the second locking slot relative to the first locking slot may be adjustable in order to adjust the height of the steering means when the foldable golf trolley is in the deployed configuration.

[75] In embodiments, the height adjustment means may have an adjusting setting in which the location of the second locking slot relative to the first locking slot may be adjusted; and a non-adjusting setting in which adjusting the location of the second locking slot relative to the first locking slot may be substantially prevented. In embodiments, the height adjustment means is configured such that it can remain in the non-adjusting setting during a transition between the deployed and collapsed configurations [76] In embodiments, the height adjustment means is biased towards the adjusting setting by one or more biasing members, e.g. springs. The height adjustment means may be closed or tightened, against the bias, to retain the height adjustment means in the non-adjusting setting between adjustments. For example, the height adjustment means may be enclosed within a housing including a partially or fully removable cover.

[77] In embodiments, the height adjustment means may include an interface between two opposing notched (e.g. serrated) surfaces which are moveable relative to one another in the adjusting setting and which are substantially coupled to one another in the non-adjusting setting. For example, the biasing means may force the opposing notched surfaces apart from one another upon loosening of the cover of the height adjustment means, allowing the notched surfaces to be moved relative to one another. Thus, different height settings of the steering means may be provided, with each successive alignment between the opposing notched surfaces being a distinct height setting. In embodiments, one or both of the opposing notched surfaces of the interface may be substantially crescent-shaped.

[078] In embodiments, the opposing notched surfaces may be biased away from one another by a spring or the like and the opposing notched surfaces may be coupled to one another against the action of the spring in the non-adjusting setting.

s [079] In embodiments, the height adjustment means is configured to allow adjustment of the height of the steering means between around 50 cm and around 150 cm in height.

[80] In embodiments, the frame of the foldable golf trolley may be foldable lengthwise and may include one or more joints. In embodiments, the foldable golf trolley may include a said height adjustment means proximal at least one said joint.

[81] In a further aspect, the present invention provides a height adjustment mechanism for a foldable golf trolley having a collapsed configuration and a deployed configuration and including a steering means, wherein the height adjustment means may be configured such that an adjusted height of the steering means is repeatably automatically reached when the foldable golf trolley is transitioned from the collapsed configuration to the deployed configuration. Additionally, or alternatively, the height adjustment means may be configured such that an adjusted height of the steering means is repeatably automatically reached when the foldable golf trolley is transitioned from the deployed configuration to the collapsed configuration. In embodiments, the height adjustment mechanism is configured to be substantially wholly integrated with the foldable golf trolley. In embodiments, the height adjustment means may be operable substantially without the use of a separate tool. In embodiments, the height adjustment means may be operably with the use of a separate tool, for example where a user has impaired grip.

[82] In embodiments, the height adjustment mechanism may comprise one or more locking pins. In embodiments, the one or more locking pins may be configured to remain as part of the golf trolley throughout an adjustment of the steering means. In other words, the height of the steering means may be adjustable without the need to remove a locking pin or other part of the golf trolley from the remainder of the trolley.

[83] In embodiments, the height adjustment mechanism may include a first locking slot for a said locking pin when in the collapsed configuration of the foldable golf trolley; and a second locking slot for the locking pin when in the deployed configuration of the foldable golf trolley. In embodiments, the location of the second locking slot relative to the first locking slot may be adjustable in order to adjust the height of the steering means when the foldable golf trolley is in the deployed configuration.

[84] In embodiments, the height adjustment mechanism may comprise an adjusting setting in which the location of the second locking slot relative to the first locking slot may be adjusted; and a non-adjusting setting in which adjusting the location of the second locking slot relative to the first locking slot may be substantially prevented. In embodiments, the height adjustment mechanism may be configured such that it can remain in the non-adjusting setting during a transition between the deployed and collapsed configurations.

[85] In embodiments, the height adjustment mechanism may be configured for an foldable electric golf trolley and/or a non-electric, e.g. push-type, golf trolley.

[86] For the avoidance of doubt, features of aspects and embodiments described herein may be combined, and still fall within the scope of the present invention.

lo Detailed Description

[105] Figures 1 to 3 show part of a foldable electric golf trolley according to the present invention, referenced generally as 10. The foldable electric golf trolley comprises a base 12 including a plurality of wheels 14, and a frame 16. Only part of the frame is shown (an upper part of the frame is not shown). Generally, the frame 16 includes a steering means in the form of a handlebar, which is described in greater detail below.

[106] The foldable electric golf trolley 10 also comprises a battery mounted in a 20 battery port or socket, a motor or motors, a transmission or gearbox and other powerable components.

[107] The base 12 of the foldable electric golf trolley of Figures 1 to 3 includes two base segments. A first base segment 18 includes a front wheel. The front wheel is typically a non-driven wheel. A second base segment 20 includes two rear wheels located on either side of the second base segment 20. Both rear wheels are driven by the motor(s).

[108] The golf trolley 10 also includes means 22 for supporting a golf bag, or other golfing equipment.

[109] The electric golf trolley 10 is typically formed of a combination of plastics and metal.

[110] As illustrated through Figures 1 to 3, the foldable electric golf trolley 10 is configured to transition between a collapsed configuration, in which the golf trolley 10 may typically be stored or transported, for example, and a deployed configuration. In the deployed configuration the golf trolley 10 is in a driveable state.

[111] The base 12 includes a hinged attachment 24 between the first base segment 18 and the second base segment 20 such that the first base segment 18 is moveable relative to the second base segment 20. A hinged attachment 26 is also provided between the frame 16 and the second base segment 20 such that the frame 16 is moveable relative to the second base segment 20. The hinged attachment 24 between the first base segment 18 and the second base segment 20 and the hinged attachment 26 between the frame 16 and the second base segment 20 are at substantially opposite ends of the second base segment 20.

[112] During a transition between the deployed configuration and the collapsed configuration, the frame 16 moves relative to the base 12 and the first base segment 18 also moves relative to the second base segment 20.

[113] The frame 16 and the first base segment 18 are moveably coupled to one another such that their movement is interdependent. Movement of the frame 16 relative to the base 12 necessitates movement of the first base segment 18 relative to the second base segment 20, and vice versa. In short, the moveable parts of the foldable electric golf trolley move in unison during a transition between the deployed and collapsed configurations. Preferably, the frame 16 and first base segment 18 move in unison during both a transition from the deployed configuration to the collapsed configuration and in a transition from the collapsed configuration to the deployed configuration, although it is envisaged that they may only move in unison in one transition direction.

[114] Figure 2 shows the foldable electric golf trolley 10 during a transition between the deployed configuration of Figure 1 and the collapsed configuration of Figure 3.

[115] The golf trolley of Figures 1 to 3 is configured such that the frame 16 and first base segment 18 are in touching engagement with the second base segment 20 in the collapsed configuration. During a transition from the deployed configuration towards the collapsed configuration, the first base segment 18 folds substantially underneath the second base segment 20 and rests against an underside of the second base segment 20 in the collapsed configuration.

[116] The frame 16 typically comprises a single elongate stem (shown in Figures 11 and 12) which is provided with a joint 66 approximately half way along the length of the stem, such that the frame folds in a substantially concertinaed fashion during a transition towards the collapsed configuration. A lower half 46 of the frame typically rests against a top surface of the base 12 in the collapsed configuration, with an upper half 48 of the frame resting on the lower half.

[117] In some embodiments, as mentioned above, the interdependent nature of the movement of these components may only exist in one direction of transition. For example, movement of the frame 16 and first base segment 18 may be substantially interdependent during a transition from the deployed configuration to the collapsed configuration, and the frame 16 and first base segment 18 may be separately moveable, e.g. unfoldable, during a transition back to the deployed configuration. However, in the embodiment of Figures 1 to 3, movement of the frame 16 and the first base segment 18 is interdependent both during a transition from the collapsed configuration to the deployed configuration and during a transition from the deployed configuration back to the collapsed configuration.

[118] Referring back to Figures 1 to 3, the driven wheels of the second base segment 20 remain relatively static on the ground during a transition between the deployed configuration and the collapsed configuration, and the second base segment 20 rotates relative to each of the driven wheels. The frame 16 and first base segment 18 also move relative to the wheels of the second base segment 20 during a described transition.

[119] The second base segment 20 preferably includes a support surface 44 such that, when the foldable electric golf trolley 10 is in the collapsed configuration, it stands on a support structure comprised of the two rear driven wheels and the support surface 44 of the second base segment 20. 23.

[120] Referring now to Figures 4, Sand 6, it can be seen than the frame 16 and first base segment 18 are coupled to one another via two connecting members 28, 32. Each connecting member 28, 32 is in the form of a strut. The strut is generally formed of metal, but may be formed of plastic or of a composite material, or a combination thereof.

[121] A first connecting member 28 is connected to the hinged attachment 26 between the frame 16 and the second base segment 20 and the hinged attachment 24 between the first base segment 18 and second base segment 20. The first connecting member 28 is connected to each hinged attachment 24, 26 via a coupling 30 which has a substantially tear drop shaped outer portion. The connecting member 28 is rotatably connected to the couplings 30, and the couplings 30 are substantially fixedly attached to the frame 16 and first base segment 18 and the hinged attachments 24, 26. Thus, during a transition between the deployed and collapsed configurations, the connecting member 28 and couplings 30 rotate relative to one another.

[122] A second connecting member 32 is similarly connected to the hinged attachments 24, 26. The connecting members 28, 32 are configured such that the 20 frame 16 and first base segment 18 move substantially synchronously during a transition between the deployed and collapsed configurations.

[123] The hinged attachments 24, 26 are geared due to the difference in their size. The hinged attachment 24 between the first base segment 18 and the second base 25 segment 20 is smaller than the hinged attachment 26 between the frame 16 and the second base segment 20.

[124] The two connecting members 28, 32 flank the battery pod 34 (and the battery when it is in situ). That way, the battery, motor and means that connect the battery to 30 the motor can remain substantially where they are generally accepted to be best-placed in a foldable electric golf trolley.

[125] As shown best in Figure 4, generally the connecting members 28, 32 fit between the battery port 34 and motors 36 of the foldable electric golf trolley 10.

Therefore, the overall size of the foldable electric golf trolley 10 need not increase substantially.

[126] Referring to Figures 6 and 7, the connecting members 28 each have a substantially bent profile, having two end segments 38, 40 which are inclined in opposing directions from a middle segment 42. It may be, in other embodiments, that the connecting members 28 have a relatively straight profile, as shown in Figure 5.

[127] When the foldable electric golf trolley 10 is in either the deployed configuration or the collapsed configuration, the foldable electric golf trolley 10 is also in a relatively locked state. In the locked state, the frame 16 and the first base segment 18 are substantially prevented from moving relative to the second base segment 20. Therefore, when the foldable electric golf trolley 10 is in the deployed configuration or collapsed configuration, the frame 16 and first base segment 18 may not move relative to the second base segment 20 unless the electric golf trolley 10 is transitioned from the relatively locked state to a relatively unlocked state.

[128] The foldable electric golf trolley 10 is in a relatively unlocked state between the deployed and collapsed configurations, and in the relatively unlocked state the frame 16 and first base segment 18 are substantially free to move relative to the second base segment 20.

[129] A single actuator is configured to transition the foldable electric golf trolley 10 from the relatively locked state to the relatively unlocked state and thus to allow a transition of the foldable electric golf trolley 10 from at least one of the deployed and collapsed configurations towards the other, but preferably from both the deployed and collapsed configurations.

[130] The actuator includes a user-engageable control in the form of a lever 50, see Figures 11 and 12, and biased locking members located at the joint of the frame 16 and at the hinged attachment 26 between the frame 16 and the second base segment 20. In use, operation of the level 50 by user moves each of the locking members against their direction of bias in order to transition the foldable electric golf trolley 10 from the locked state in either the deployed configuration or the collapsed configuration to the unlocked state, so that the frame 16 and first base segment 18 may be freed to move. The lever 50 is directly connected to a locking member at the joint of the frame 16 and connected to a locking member at the hinged attachment 26 via a cable or the like.

[131] Referring to Figure 13, the actuator includes a biased locking member in the form of a spring-biased pin 60 which is operably engaged by the lever 50. The spring-biased pin 60 has a first locking location in a first locking slot 62 when the foldable electric golf trolley 10 is in the deployed configuration and a second locking location in a second locking slot 64 when the foldable electric golf trolley 10 is in the collapsed configuration. The first and second locking slots 62, 64 form part of the frame joint 66. In use, the lever 50 is pushed against the action of a spring (not shown) which biases the pin towards a locking location and the foldable electric golf trolley 10 is transitioned from one to the other of the collapsed and deployed configurations. The pin 60 slidingly engages a surface of the joint until the other locking location is reached, at which point the spring biases the pin 60 into a locking engagement in the other locking location. As described in greater detail below, the joint 66 also includes a height adjustment means which is arranged such that the distance between the first and second locking locations 62, 64 can be adjusted to adjust the height of the steering means of the frame zo 16.

[132] Referring back to Figures 6 and 7, the actuator also includes a biased locking member in the form of a spring-biased bar (not shown) at or near the hinged attachment 26 between the frame 16 and second base segment 20. The spring-biased bar has a first locking location 52 when the foldable electric golf trolley 10 is in the deployed configuration and a second locking location 54 when the foldable electric golf trolley 10 is in the collapsed configuration. The first and second locking locations 52, 54 are each in the form of an elongate groove in which the spring-based bar resides in the corresponding trolley configuration. The elongate grooves are arranged on a cam 58 associated with the bottom of the frame 16. Typically, as the lever 50 is operated, the spring biased bar is pulled from whichever locking location it is located in and, as the foldable electric golf trolley 10 is transitioned to the other of the collapsed or deployed configurations, the spring-biased bar slides over a rounded contact surface of the cam until it reaches the other elongate groove. In use, the bar remains relatively static relative to the second base segment 20 in order that rotation of the frame 16 relative to the second base segment 20 about hinged attachment 26 causes the bar to slide across the rounded contact surface until it reaches a locking location.

[133] As illustrated in Figure 8, a spring 56 biases the bar towards the locking locations (i.e. the spring pulls the bar against the rounded contact surface) so that the bar reliably slides into one of the locking locations as the foldable electric golf trolley 10 reaches one of the collapsed and deployed configurations.

[134] Thus, the lever 50 operably engages two sets of biased locking members in order to prevent movement of the parts of the frame in the locked state and to prevent movement of the frame 16 relative to the second base portion 20 in the locked state. Also, by virtue of the interdependency of the frame 16 and first base segment 18, preventing movement of the frame 16 relative to the second base segment 20 also prevents movement of the first base movement 18 relative thereto.

[135] Figures 9 and 10 show how the couplings 30 are fixedly attached to the frame 16 and first base segment 18 at the hinged attachments 24, 26. In particular, notched circumferential surfaces of the couplings 30 interlock with corresponding notched surfaces of the cam at the frame 16 and the first base segment 18. Each coupling 30 comprises two segments which are joined to one another such that they rotate substantially in unison together with the frame 16 or first base segment 18.This joint may be referred to as a castellated joint.

[136] Referring to Figures 11 and 12, the foldable electric golf trolley 10 further comprises a height adjustment mechanism, generally referenced 100. The height adjustment mechanism 100 allows the height of the steering means 68 in the deployed configuration to be adjusted through around 35 degrees (although a greater or lesser extent of adjustment may be provided). The height adjustment mechanism is substantially entirely integrally formed with the golf trolley 10, so that separate devices or tools are not required in order to adjust the height of the steering means. Also, during an adjustment of the height of the steering means 68, no part of the height adjustment mechanism must be removed from the electric golf trolley.

[137] The height adjustment mechanism 100 forms part of the joint 66 and is configured such that an adjusted height of the steering means 68 is repeatably automatically reached when the foldable electric golf trolley 10 is transitioned from the collapsed configuration to the deployed configuration, through successive iterations of the transition. More specifically, and with particular reference to Figure 13, the height adjustment mechanism 100 allows the spacing between the first and second locking slots 62, 64 to be adjusted, e.g. made larger or smaller.

[138] The height adjustment mechanism is operably engageable by the actuator and specifically the spring-biased pin 60 at the joint 66.

[139] The joint 66 includes an upper housing 104 and a lower housing 106. The upper housing 104 includes the second locking slot 64 for the spring-biased pin 60. The first locking slot 62 for the spring-biased pin 60 is arranged on a moveable slider 108 which is housed within the upper housing 104. In use, it is the movement of the slider which adjusts the spacing between the first and second locking slots 62, 64 in order to adjust the height of the steering means in the deployed configuration.

[140] The upper housing 104 also includes an elongate slot 109 which is aligned with the first locking slot 62 in order that the pin 60 can enter the first locking slot 62 on the moveable slider through the upper moulding 104 regardless of the location of the slider 108.

[141] The pin 60 is biased towards a locking position, e.g. it is forced towards an axis of rotation of the joint 66, so that the pin 60 slots into the first or second locking slot 62, 64 as the foldable golf trolley reaches the corresponding deployed or collapsed configuration. In use, operation of the lever 50 pulls the pin 60 out of the first or second locking slot 62, 64 in order that the frame may fold.

[142] The moveable slider is attached to a spring-loaded cam 110 also housed within the upper housing 104.

[143] The height adjustment means 100 has an adjusting setting in which the location of the second locking slot 64 relative to the first locking slot 62 may be adjusted, and a non-adjusting setting in which adjustment may be prevented. The height adjustment means 100 is in the non-adjusting setting when the spring-loaded cam 110 is clamped against its direction of bias. If a clamping force on the spring-loaded cam 110 is released or relaxed, the spring-loaded cam and slider 108 are moveable orbitally around the rotational axis of the joint 66 to move the first and second locking slots 62, 64 closer or further away from one another.

[144] As shown in Figure 14, both the spring-loaded cam 110 and an opposing surface of the upper housing 104 are serrated in order that the spring-loaded cam 110 securely couples to the upper housing 104 in the non-adjusting setting. The spring-loaded cam 110 is biased away from the opposing surface of the upper housing 104 by a spring 112. A screw 114 and corresponding nut 116 (which is operable without the need of a separate tool, e.g. with the hand of a user) when tightened, hold the spring-loaded cam 110 against the serrated surface of the upper housing 104 against the bias of the spring 112. It is envisaged, however, that a separate tool may be provided for operating the height adjustment mechanism, for example where it is desirable to prevent a user from adjusting the height of the steering means without a tool or where a user may have impaired grip strength.

[145] As shown in Figures 15 to 17 (where Figure 15 illustrates a section view of the height adjustment means 100), the height adjustment means 100 comprises two pins 60 which locate in two slides 108 located on opposing sides of the upper housing 104. A cover 118 prevents the spring-loaded cam 110 and slider 108 from exiting the joint 66 when the height adjustment means 110 is in the adjusting setting.

[146] The height adjustment mechanism 100 shown in Figures 11 to 17 may be provided in a foldable golf trolley also comprising the interdependent aspects described above, or may be provided in any other foldable golf trolley (e.g. one not also including the interdependent aspects described above). A golf trolley including the height adjustment mechanism may be a non-electric, e.g. push-type foldable golf trolley.
