Transporter and Basket

technical field

The invention relates to a stackable, hand-movable transport vehicle having a frame, a pusher, a brake and a storage area for goods, luggage or the like. Furthermore, the present invention relates to a basket for storing items.

Background technique

Such trolleys are known from the prior art in the form of so-called luggage trolleys. The transporter is usually equipped with three or four rollers and has a storage area. A beam as described below is provided on which the pusher is arranged. Most of the vehicles are provided with brakes which can be released by pressing down on the pusher. For example, EP 1 590 224 B1 proposes a vehicle with a braking device. An L-shaped trigger part is arranged on the lower side of the storage area. Said triggering means makes it possible to release the brakes of identical cars when they are stacked on top of each other, thereby enabling a train to be moved in a simple manner. The release of the brake device takes place, in particular, by raising the brake release device, which is embodied, for example, in the form of a web. The tabs are arranged in operative connection with the brake link and point into the inside of the vehicle.

The vehicle can additionally have connectors. Such connectors are disclosed, for example, in EP 0 722 846 B1. The connector is located on the back side of the frame. Two joint pieces are used to carry the beam on the one hand. The beam is inserted into the joint from above. Furthermore, two walls are provided which are intended to carry the wheels. The joint piece is part of an extruded profile, wherein the fastening region of the joint piece is hollow. A space is provided between the wall and the wheel outside each fixing area for receiving a portion of the braking device.

The storage area for luggage, merchandise and the like consists of rods which are part of an extruded profile. The beams of the car are also part of the extruded profiles. Alternatively, tubes or other hollow profiles are conceivable.

Usually at least the joint pieces, as well as the rods and beams, are also made of aluminium material.

In addition, the carts are typically equipped with wire baskets for storing hand luggage or other smaller items. The basket is arranged on the inner side of the beam and preferably has an additional floor-like protective panel, which can be installed replaceably.

Furthermore, EP 2 230 150 B1 describes a transport vehicle with front clips. The cart is equipped with the clips and prevents undesired slipping of boxes, bags or other items.

SUMMARY OF THE INVENTION

The object of the present invention is to propose an improved transport vehicle and an improved basket.

The invention solves this task by means of the features of claim 1 . Therefore, the stackable hand-movable transport vehicle is equipped with a carriage, wherein rollers are arranged on the carriage, wherein the carriage is provided with upwardly standing beams, which carry the pusher, wherein, in addition, by means of the pusher Brakes can be activated, wherein the frame has a storage area for goods, luggage or the like, wherein an upper basket is provided, wherein the vehicle is additionally equipped with at least one joint with a bearing for carrying The fixing area of the beam, wherein two walls are provided on the fixing area, which walls form a space for the braking device, wherein the space is protected by an upper cover, which has a space for receiving the brake. opening of the beam and surrounding the beam.

As a result, a simplified arrangement of the beams can be ensured and a reduction in the use of aluminium profiles as beams is also achieved through the additional stabilization. The two parts, namely the beam and the rest area, are preferably additionally welded to each other as part of the frame.

The braking device can be protected by an upper cover. Damage or contamination can be prevented.

The cover can consist of plastic here and be arranged on the wall in a replaceable or stationary manner.

Furthermore, the cover may have a predominantly horizontal area and a slightly inclined area, wherein the opening for receiving the beam may preferably be provided in the predominantly horizontal area. The cover thus provides a face sufficient for receiving the beam. The shape of the cover is furthermore disturbed neither during the stacking process nor when the cart is pushed.

Furthermore, it is conceivable that the trigger element is arranged on the underside of the lever in the storage area.

Two different types of trigger elements can be used here. A trigger element can be provided, which enables the lifting of the preceding identical, stacked carts. However, a trigger element can also be provided, which actuates the brake release and releases the brakes of the vehicle ahead. In both embodiments, the carts can be moved in a simple manner stacked in rows.

It may prove useful if the brake release device is arranged on the inner wall. The brake release device thus functions undisturbed during movement.

Furthermore, the brake release device can have a flat area which is provided for arranging the brake release device on the inner wall. The inner wall has openings for enabling the interaction of the brake device with the brake release device.

In this case, the brake release device can have a region extending into the interior of the vehicle, which region is directly operatively connected to the trigger element for releasing the brake. This ensures easy release of the brakes in a state where two or more vehicles are stacked.

In addition, the vehicle can be equipped with a flip clip in the front area.

The invention further solves the object by the features of claim 10 . A kind of basket for transport vehicles is therefore provided.

The basket can be manufactured as easily engageable elements that can be plugged into each other or clamped. Extruded aluminium profiles are used on wide side walls to achieve low weight and flexible basket size as required. Also consider the use of signage and/or advertising. The identification plates or advertisements can be arranged in a replaceable manner, for example glued.

The side walls made of plastic, preferably PP, allow easy assembly, an advantageous product and, if necessary, a quick replacement.

In order to ensure stability, it may prove useful to provide at least one reinforcing rib in the side part made of plastic.

Provided with an open bottom portion, the bottom portion reduces material usage and thus weight. The bottom part is provided, for example, by a plastic, sheet or wire part. In addition, contamination of the basket can thus be prevented.

Baskets can be provided cost-effectively through the more simplified product type. Additional reinforcement elements can be eliminated. Different materials can also be used, such as in particular aluminium and plastic.

In particular, the beam can be additionally fixed and stabilized in receptacles provided in the narrow side parts.

Preferably, the components of the basket and here in particular the side parts are additionally fastened by means of fastening elements.

A basket size in the range of 18 to 20 liters is advantageous and provides sufficient space for storing smaller items.

Detailed ways

FIG. 1 shows a stackable and hand-movable transport cart 10 having a carriage 20 . The frame 20 is equipped with beams 24 that stand up. The beam 24 carries the pusher 30 . The brake 90 can be released by pressing down on the pusher 30 . The frame 20 has a storage area 22 for merchandise, luggage and/or the like. The rollers 80 are arranged on the frame 20 . The illustrated transport cart 10 has three rollers 80 . Other numbers of rollers, such as four or five rollers, are contemplated.

The trigger element 40 correspondingly lifts the rollers of the preceding moving vehicle, so that a train can be moved in a simple manner.

The basket 70 is arranged in the upper area. The basket receives beams 24 and surrounds the beams. The beam 24 extends into the joint piece 60 which receives the roller 80 and surrounds the braking device 92 . The fastening region 62 is provided in particular for the support beam 24 . Two walls 63 are provided on the fastening region 62 , which walls form a space 64 for the braking device 92 .

The space 64 is protected by the upper cover 65 . The cover 64 has an opening 69 for receiving the beam 24 . Furthermore, the opening 69 surrounds the beam 24 . The cover 65 preferably consists of plastic and is arranged on or at the wall 63 in a replaceable or stationary manner. The cover 65 consists of a mainly horizontal area and a slightly inclined area ( 66 , 67 ), wherein the opening 69 for receiving the beam 24 is provided in the mainly horizontal area 66 .

The trigger member 40 is arranged on the underside of the rod 28 of the rest area 22 . Said rod 28 is preferably manufactured as an aluminium profile, which can have the cross-section shown in FIG. 9 . Material savings in the range of about 20 to 40% can be achieved compared to conventional aluminium profiles. In particular the wall thickness is reduced eg from 3 mm to 2 mm. Furthermore, openings for the grooves 110 are provided, which openings can receive the crash profile 100 . This further reduces material usage. The resistive moment can be increased by the geometry shown in FIG. 9 so that the wall thickness can be correspondingly reduced. The weight of the vehicle can be reduced due to the reduced material usage, so that the movement of the vehicle can be improved in an advantageous manner. Furthermore, manufacturing costs can be reduced.

A crash profile 100 is arranged in the lower region in the region of the joint part 60 . The same crash profile 100 is preferred, which is inserted into the groove 110 . The crash profile 100 preferably ends in the region of the joint part 60 and is arranged thereon in a stationary manner. Rivets are provided for this purpose. Plastic, for example PU, is provided as the material for the crash profile 100 . A length of approximately 1600 mm of crash profile 100 is used for the entire vehicle 10, 10'.

Trigger member 40 is shown in FIGS. 2 and 3 . The trigger element is L-shaped. The trigger element has a core 42 which is provided with a cutout 41 in order to save material. The recesses 41 are formed in a quadrangular shape. Other shapes can be considered. Furthermore, a cover 43 is provided, which is preferably made of an elastic material, for example plastic. The cover 43 can be plugged onto the trigger part 40 in an exchangeable manner and fastened. Easy replacement is possible.

FIG. 4 shows an additional embodiment of a transporter 10'. The transport cart has a flip clip 50 . Furthermore, a trigger element 44 is provided, which is designed to be operatively connected to the brake release device 94 , as a result of which the brake device 92 or the brake 90 can be released. The trigger element 44 is likewise arranged in a fixed position on the underside of the lever 28 of the rest area 22 .

FIGS. 5 a , b, c show the specific mode of action of the brake release device 94 and the trigger element 44 . In Figure 5a, the vehicle 10' is braked. A brake release device 94 is arranged on the inner wall 63a. In particular, the inner wall has a flat region 96 which is provided for arranging the brake release device 94 on the inner wall 63a. The flat region 96 is mounted such that it can move. The opening 68 is provided as a guide.

Figure 5b shows, for example, that the brake 90 is released when the second vehicle 10' is pushed in. For this purpose, the brake release device 94 has a region 98 extending into the interior of the vehicle 10 ′. This region is directly operatively connected to the trigger element 44 for releasing the brake 90 .

The trigger member 44 is equipped with stops which limit the movement of the vehicle 10' behind. This is shown in Figure 5c. The stop acts directly on the area 98 extending into the interior of the vehicle 10' and lifts the brake 90 through a lever mechanism, thereby releasing the brake 90 and moving the vehicle 10'.

Figure 6a again shows the braked vehicle 10'. In Figure 6b, the brake is released.

FIG. 7 shows a basket 70 having two wide side portions 72 and two narrow side portions 74 . Receptacles 76 for the beams 24 are provided in the narrow side portions 74 . Preferably, the wide side portions 72 are fabricated from extruded aluminum profiles, and the narrow side portions 74 are fabricated from plastic.

Figure 8 shows the same basket 70 broken down into individual components. All parts are plugged or clamped to each other and preferably screwed. The bottom part 77 is provided with an opening 78 . The opposite wide side sections 72 can be formed from the same aluminium profile or from different aluminium profiles as shown.

As shown in FIGS. 10 to 13 , the cart 10 ′ has a flip clip 50 . For use, the flip clip opens into a nearly vertical position. In this position, clip 50 protects items located on cart 10' from falling.

The clip 50 may also be used in the first cart 10 .

The clip 50 is placed in the area in front of the vehicle 10'. For this purpose, a device 52 for receiving the clip 50 is provided in the area in front of the vehicle 10 ′ between the two bars 29 inside the resting area 22 . The clip 50 can also be placed after the fact if desired. The device 52 realizes that the clip 50 is mounted so as to be rotatable. Fig. 10 shows the usage position.

The area between the two rods 29 provides, as can be seen from FIG. 11 , sufficient space for arranging the means 52 for receiving the clip 50 . Replaceable or fixed-position arrangements can be selected. In particular, the holding area of the front roller 80 , which is likewise arranged between the two rods 29 , but below the rest area 22 , also provides sufficient space for arranging the device 52 for receiving the clip 50 . . The holding area 54 of the device 52 provides a sufficient level for the permanent and/or replaceable arrangement of the device 52 on the upper side of the roller receptacle.

The two rods 29 are also used for the fixing means 52 . The preferably elliptical embodiment of the rod 29 is based here, in particular using the inner wall of the rod 29 accordingly. The device 52 can be permanently and/or replaceably arranged on the inside of the rod 29 in a simple manner.

As can be seen from FIG. 12 , the two intermediate rods 29 are spaced apart so that the clip 50 can be securely retained between the two rods 29 in the unused position. The clip 50 has slightly curved corners, see eg FIG. 14 . The angled portion is preferably designed such that the angular region does not lie above the upper edge of the rod 29 in the unused state. The clip 50 thus functions without interference even when the storage area 22 of the vehicle 10' is loaded. The lower region of the clip 50 acts as a stop due to the slight bend. The lower region of the clip 50 can be moved until it hits the holding region 54 of the device 52 . The holding region 54 of the device 52 thus ultimately forms a stop for the clip 50 . This is derived from Figure 15.

This prevents the clip 50 from reaching deeper into the vehicle interior or, in the worst case, rubbing against the ground. The arrangement between the two rods 29 furthermore provides guide means for the clip 50 . Slippage can be avoided. It is also possible to exclude the possibility that the clip 50 occupies the wrong position.

The clip 50 is shown in its unused position in FIGS. 12, 13 . The clip is supported between two rods 29 . Due to the slight bend in the upper region of the clip 50, the clip is partially supported below the resting area 22 and below the rod 29 in the unused position. The clips function without interference when the same carts 10, 10' are stacked.

The function of the flip clip 50 is designed in such a way that the spring 56 arranged inside the shaft is preloaded with a torsion force. This achieves the desired effect that the upwardly standing clip 50 is always present. When stacking identical carts 10 , 10 ′, the clip 50 can then be flipped down against the resistance of the spring 56 in a simple manner towards the center of the cart. When the carts 10 , 10 ′ are removed from a row of identical carts 10 , 10 ′, the clips 50 are then flipped back into their use position on the basis of the preset springs 56 . Due to this configuration, there is no longer a crush point when the clip 50 is turned upwards.

The holding area 54 can be mounted on a conventional frame of the vehicle 10 , 10 ′ in a simple manner. Embodiments that maintain the level of region 54 have been shown to be advantageous. Perforations are preferably provided here. Said perforations serve to receive the holding means 52 of the clip 50 on the frame 20 of the vehicle 10', eg by means of a bolted or rivetted connection. In addition to the holding region 54 , a receptacle for the spring 56 and a protective device 58 are provided. The receptacle 58 is a cylindrical cover for the spring 56 which provides sufficient protection for the spring 56 . The holding area 54 is preferably formed in a square shape and is mounted on the receptacle 58 in a fixed position.

Furthermore, additional securing devices 59 are provided, which also serve to ensure a permanent and/or positionally fixed mounting of the device 52 on the vehicle frame 20 or the roller receptacle.

As can also be seen from views 14, 15 and 16, clip 50 is made of round wire. The clips are mounted stationary on the receptacle 58 and act directly on the spring 56 .

The device 52 thus preferably consists of at least the holding area 54 , the receptacle 58 for the spring 56 and the fixing device 59 , which is attached to the device 52 and which is provided for arranging the device on the vehicle 10 . , 10' on the frame 20.

Furthermore, as can be seen from FIGS. 14 to 16 , two semicircular bends 53 are provided, which have circular perforations 55 . The two opposing bores 55 receive the receptacles 58 of the spring 56 . The opposite perforations 55 are of the same size and are designed in such a way that they can be used for the cylindrical receptacle 58 received by the spring 56 and ensure a rotational movement of the receptacle 58 . The bend 53 also enables an additional attachment to the rod 29 .

As can be seen from FIG. 16 , the spring 56 is arranged on the end cap 51 which is operatively connected to the receptacle 58 . A cylindrical pin 57 secures the end cap 51 to the spring 56 in the receptacle 58 for the spring 56 . For this purpose, the end caps 51 have corresponding openings. Furthermore, the receptacles 58 also have corresponding openings, which are likewise provided for inserting the pins 57 for fixing the springs 56 . The dimensions, ie the length and the cross section, of the pins 57 are different here.
