Description

Equipment for carrying scooter

Technical Field

The present invention relates to transportation equipment and may be used in the design of scooters to carry scooters.

Background

When using a scooter, there are often situations where the rider needs to carry it by hand for a short period of time, for example when going down or up stairs, passing through a sidewalk, crossing an obstacle, the rider needs to go up and down from the scooter and carry it over the obstacle. Prior to such short transport, it is desirable to lock the steering column of the scooter to prevent the steering column and steering wheel from rotating relative to the frame of the scooter, which may make transport more uncomfortable. The steering column may also need to be locked when the scooter is carried for a long time or transported using other transport means.

Presently, foldable scooters known in the art allow their handling or storage in a folded state. See, for example, RU patent nos. 2562085C1, IPC B62K 15/00, which are disclosed on 9,10, 2015. The design of the foldable scooter increases the convenience for carrying the scooter to a certain degree, or the size of the foldable scooter is smaller when the foldable scooter is stored. However, this design is hardly suitable for comfortable handling of the scooter for a short period of time, since it does not provide a quick and easy transition for the scooter to be handled with its steering column locked, nor does it provide the same quick and easy transition for returning the scooter elements to the operating state (coasting state).

Scooters equipped with handlebar locking mechanisms are also known, see for example patent applications WO 2014/113903 a1, IPC B62K 21/16 published on 4/31 2014. This locking mechanism locks the handlebar and the steering wheel of the scooter together to prevent rapid theft of the scooter, but also does not provide for rapid and easy switching of the scooter for ease of handling when locking its steering column, nor does it provide for equally rapid and easy switching of the scooter elements back to the operating state (the sliding state).

Therefore, there is a need for an apparatus for comfortably carrying a scooter.

Disclosure of Invention

The object of the present invention is to provide an apparatus for comfortably carrying a scooter. The technical effect provided by the invention is to provide quick and convenient conversion of the scooter for converting the scooter from a working state (a sliding state) to a transportation or storage state convenient for transportation or storage by locking the steering column, and vice versa.

Said object is achieved by the technical result provided by the handling device, according to the invention a device for handling scooters is provided. The apparatus includes a carry handle adapted to be mounted on a steering column of the scooter and rotatable in a vertical plane, and a locking mechanism for preventing rotation of a frame of the scooter relative to the steering column when the carry handle is in a horizontal position for carrying or storing the scooter.

According to the present invention, the locking mechanism preferably comprises a fixed member, a movable member, a pulling member and a double-armed lever. The mount is adapted to be rigidly secured to a head tube of the scooter and has circumferentially arranged teeth. The movable member is adapted to be mounted on the steering column, exerts a spring force vertically with respect to the stationary member, and has circumferentially arranged teeth adapted to mesh with the teeth of the stationary member. The double-armed lever is adapted to be pivotally mounted on the steering column. One arm of the lever is in contact with the movable member and the other arm of the lever is pivotally connected to the lower end of the pulling member. The upper end of the pulling piece is pivotally connected with the carrying handle.

Furthermore, the double-armed lever can be made in a curved form to partially surround the steering column. The pulling member may be made in the form of a rigid rod or in the form of a flexible cord.

The carrying handle is preferably provided with a stopper for locking the carrying handle in a horizontal position and adapted to be mounted on the steering column by means of a cantilever.

Preferably, the carrying handle and the boom have coaxial horizontal through holes, the axis of which is the pivot axis of the carrying handle. Each bore has a partial radial groove. The stopper is made in the form of a cylindrical element, placed in the holes of the carrying handle and the boom, and has a radial projection placed in a recess of the carrying handle. The recesses of the carrying handle and the cantilever arm are arranged to provide the possibility of aligning the recesses when the carrying handle is in a horizontal position. The cylindrical member can be moved horizontally when the carry handle is in a horizontal position so that the protrusion enters the recess of the cantilever arm.

In order to fix the carrying handle in its pre-horizontal position for short periods of time when carrying the scooter, the cantilever arm has a rounded corner with two fixing recesses which are arranged on a circle about the pivot axis of the carrying handle. The carrying handle is provided with a horizontal rolling shaft, a pressure lever and a spring. The pressing rod is installed on the carrying handle and is contacted with the rolling shaft so as to vertically rotate. One end of the spring interacts with the free end of the strut to ensure constant pressing of the roller against the fillet and possible partial entry of the roller into the fixing recess when the carrying handle is in the fully lowered and pre-horizontal position, respectively.

Detailed Description

A typical scooter equipped with a handling device according to the invention comprises a steering column 1 mounted in a head tube 2, the head tube 2 being rigidly connected to a frame 3 of the scooter. The carrying apparatus has a carrying handle 4 mounted on the steering column 1 for rotation in a vertical plane, and a locking mechanism for preventing the frame 3 from rotating relative to the steering column 1 when the carrying handle 4 is in a pre-level or horizontal position for carrying or storing a scooter.

The locking mechanism comprises a fixed part 5, a movable part 6, a pulling part 7 and a double-arm lever 8 (fig. 4).

The fixing member 5 is fixed to the head pipe 2 by, for example, two diametrically arranged bolts 9, and has teeth 10 (fig. 6) arranged around the circumference of the head pipe 2. The movable member 6 is mounted on the steering column 1 and exerts a vertical spring force against the fixed member 5 by, for example, two radially arranged vertical compression springs 11. Furthermore, the movable member 6 has teeth 12 (fig. 8) arranged around the circumference of the head pipe 2 so that the teeth 12 can mesh with the teeth 10 of the fixed member 5. The movable member 6 is mounted on the steering column 1 coaxially with the fixed member 5 by means of an intermediate housing 13 (fig. 6), which intermediate housing 13 rests on a set of fastening nuts 14 (fig. 7) of the steering column 1. Since the inner shape of the intermediate housing 13 is similar to that of the nut 14, it is fixed so as not to rotate about the steering column 1.

On the side of the steering column 1, a horizontal through hole is defined in the intermediate housing 13. The double-armed lever 8 is mounted by means of a pivot inserted in a hole and fixed against horizontal movement by means of two screws 15 (fig. 4, 5). Thus, the double arm lever 8 is pivotally mounted on the steering column 1. The double-armed lever 8 has a curved shape partially surrounding the steering column 1. At the top of the intermediate housing 13, a clamping device 16 (fig. 4-7) is mounted around the steering column 1 and the intermediate housing 13 is secured against movement along the steering column 1 by a clamping screw 17 (fig. 4). Thus, the intermediate housing 13 is rigidly connected to the steering column 1.

The lower part of the compression spring 11 rests on an upward projection (not numbered in the figures) of the intermediate housing 13, while the top end of the compression spring 11 receives a downward projection 18 (fig. 8) on the inner surface of the movable member 6. Thus, the movable member 6 is vertically spring-loaded with respect to the fixed member 5, can rotate together with the steering column 1 about the longitudinal axis (not shown in the drawings) of the steering column 1, and can vertically move with respect to the steering column 1, the head pipe 2, and the fixed member 5.

One (short) arm of the double-arm lever 8 is in contact with the upper surface of the movable member 6, while the other (long) arm is pivotally connected to the lower end of the pulling member 7, and the upper end of the pulling member 7 is pivotally connected to the carrying handle 4.

The carrying handle 4 is mounted on the steering column 1 by means of a cantilever 19 (fig. 2, 3, 9-13), which cantilever 19 is rigidly fixed to the steering column 1 by means of a fastening clip 20. The carrying handle 4 and the cantilever arm 19 have coaxial horizontal through holes, the axis of which is the pivot axis 21 of the carrying handle 4 (fig. 9-13). Each of these through-holes of the carrying handle 4 and the cantilever arm 19 has a partial

radial recess

22 and 23, respectively (fig. 9, 10). The carrying handle 4 is provided with a stopper for locking the carrying handle 4 in a horizontal position. The stopper is made in the form of a cylindrical element 24, which cylindrical element 24 is placed in the through hole of the carrying handle 4 and the cantilever 19, and has a radial projection 25 which is constantly placed in the recess 22 of the carrying handle 4. The

recesses

22, 23 may be aligned with each other in the circumferential direction about the axis 21 when the carrying handle 4 is in a horizontal position. Thus, the

recesses

22, 23 are provided in the carrying handle 4 and the cantilever 19, respectively, such that the recesses are aligned only at the horizontal position of the carrying handle 4, and the

recesses

22, 23 are displaced relative to each other about the axis 21 when the carrying handle 4 is in any other position including the vertical position and the pre-horizontal position. The cylindrical member 24 is placed in the horizontal through hole of the carrying handle 4 and the cantilever 19, and the cylindrical member 24 is horizontally movable so that the projection 25 can enter the recess 22 when the carrying handle 4 is in the horizontal position. This horizontal movement is limited by a disc-shaped stop 26 formed at the end of the cylindrical member 24.

The cantilever 19 has a fillet 27 (fig. 11-13), the fillet 27 being in the form of, for example, a cylindrical surface with its center of rotation at the axis 21. The rounded portion 27 has two fixing

recesses

28, 29, which fixing recesses 28, 29 are arranged circumferentially around the axis 21 of the carrying handle 4. The carrying handle 4 is provided with a horizontal roller 30, a strut 31 and a spring 32, all of which are provided inside the carrying handle. The pressing lever 31 is vertically rotatable and is in constant contact with the roller 30. One end of the spring 32 continuously presses the free end of the plunger 31. Thus, a constant pressure of the roller 30 against the rounded portion 27 is ensured, so that the roller 30 can partially enter into the fixing

recess

28 or 29 at the fully lowered or pre-horizontal position of the handle 4, respectively. Thus, when the handle 4 is turned about the axis 21, the roller 30 rolls the fillet 27, the roller 30 partially enters the fixing recesses 28, 29 and, as a result of these entries, the handle 4 is fixed in the vertical position and in the pre-horizontal position, respectively. The spring 32 may be of the torsion or compression type.

In the present disclosure, the vertical or fully lowered position of the handle 4 (fig. 11) refers to a position where the handle 4 is maximally turned downward about the axis 21 and the free end of the handle 4 is fully lowered and maximally close to the steering column 1, and therefore, when skateboarding the rider, the handle 4 in this position does not become an obstacle to the rider. The horizontal position of the handle 4 (fig. 13) refers to a position where the handle 4 is maximally rotated upward about the axis 21 and the free end of the handle 4 is completely lifted up, thereby ensuring convenience in carrying the scooter. The pre-horizontal position of the handle 4 (fig. 12) refers to its intermediate position between the vertical position and the horizontal position, which is almost near the horizontal position and still facilitates short-term transport of the scooter. The angle of the handle 4 between its horizontal position and the longitudinal axis of the pre-horizontal position may be 15 ° to 20 °.

The handling device according to the invention operates by:

in the operating state of the scooter, i.e. during the sliding of the scooter, the handle 4 is in the vertical (fully lowered) position (fig. 2, 11), the lower end of the pull 7 and the long arm of the double-armed lever 8 (the right arm in fig. 4) are lowered to the maximum, and therefore the short arm of the double-armed lever 7 is raised to the maximum. In this state, the movable member 6 is in its uppermost position under the action of the compression spring 11, and the teeth 12 of the movable member 6 do not mesh with the teeth 10 of the fixed member 10. Therefore, when the movable member 6 is mounted on the steering column 1 through the intermediate housing 13, the movable member 6 can rotate about its longitudinal axis together with the steering column 1, thereby ensuring normal steering of the scooter. The handle 4 and the pull 7 occupy a minimum space behind the steering column 1 and therefore do not hinder steering.

When the handle 4 is in its vertical position, the cylindrical element 24 (stopper) is in its leftmost position (as shown in fig. 9), in which the radial projection 25 does not enter the radial groove 23 of the cantilever 19, because the

grooves

22, 23 move relative to each other about the axis 21, and therefore the cylindrical element 24 cannot fix any position of the handle 4. As described above, the handle 4 is fixed in its vertical position by partially entering the roller 30 into the fixing recess 28.

If the scooter is to be transported or stored by other means of transport, transported or stored manually for a long time, the handle 4 is switched from the vertical position to the horizontal position against the force of the compression spring 11 and the spring 32 (fig. 3, 13). As a result, the pulling member 7 rises with the handle 4, and the lower end of the pulling member 7 reaches its uppermost position together with the long arm of the two-arm lever 8. At the same time, the short arm of the double-arm lever 8 reaches its lowest position when it presses on the upper surface of the movable member 6 and overcomes the action of the compression spring 11. The movable member 6 connected to the steering column 1 in this way cannot rotate relative to the fixed member 5 and therefore relative to the frame 3 of the scooter about the longitudinal axis of the steering column 1, because of the pressure exerted by the short arm of the double-armed lever 8 on the movable member 6, the movable member 6 moves to its lowermost position and its teeth 12 engage with the teeth 10 of the fixed member 5. Therefore, the steering column 1 is stopped at the position where the handle 4, which is convenient for carrying the scooter, is in a horizontal position, and when carrying or storing the scooter, the unnecessary rotation of the scooter frame 3 with respect to the steering column 1 is prevented, thereby increasing the convenience of carrying or storing the scooter.

When the handle 4 is in its horizontal position, the radial recesses 22, 23 are aligned with each other, and by pressing the left disc-shaped stop 26 to the right, the cylindrical element 24 can be moved to its right position when the projection 25 enters the recess 23 (fig. 10), thereby preventing the lowering of the handle 4, i.e. the latter is locked in the horizontal position. By pressing the right disc stop 26 to the left, the cylindrical element 25 is moved to its left position (fig. 9), the projection 25 comes out of the groove 23, and the handle 4 is unlocked and can be lowered.

For short transport of the scooter, e.g. when transporting it over a curb, when going down stairs or going up stairs, etc., the handle 4 may not be brought to a limit level position in which the handle 4 should be locked by moving the cylindrical element 24. Instead, the handle 4 may be brought to its pre-horizontal position, as shown in fig. 12. In this position, the handle 4 is temporarily secured by the roller 30 partially entering the securing notch 29, as shown more clearly in fig. 11, 13. In this position of the handle 4, as the movable member 6 springs up relative to the fixed member 5, the

teeth

10, 12 also contact each other, and the steering column 1 is therefore also blocked and undesired rotation of the frame 3 relative to the steering column 1 is also prevented. The handle 4 can be easily moved from the pre-horizontal position to any other position simply by pressing or lifting the handle 4, so that the roller 30 rotates in the vertical plane about the axis 21 and comes out of the fixing recess 29 against the action of the spring 32. As a result, the position of the handle 4 is unlocked.

The handling device according to the invention can be mounted on a prefabricated and assembled scooter and sold as an accessory for the scooter, or can be mounted on the scooter during assembly of the scooter, after which the scooter is sold together with the loaded handling device.

As described above, the carrying apparatus of the present invention provides comfort in carrying the scooter for a short period and a long period, and convenience in storing it, and quick and convenient switching of the scooter from the working state (the sliding state) to the carrying or storing state.
