Description

Technical Field

[0001] The invention relates to a stackable, manually movable transport trolley having a frame, a sliding device, a brake and a storage area for goods, luggage or the like. The invention also relates to a basket for storing objects. Background Art

[0002] The transport trolley is known from the prior art in the form of a so-called luggage transport trolley. The transport trolley is usually equipped with three or four rollers and has a storage area. The following beam is provided, on which a push device is arranged. Most of the trolleys are provided with brakes, which can be released by pressing the push device downward. EP 1 590 224 B1, for example, proposes a trolley with a brake device. An L-shaped trigger component is provided on the lower side of the storage area. The trigger component enables the brake device of the trolley to be released when identical trolleys are stacked on top of each other, so that a train can be moved in a simple manner. The release of the brake device is carried out in particular by lifting a brake release device, which is implemented, for example, in the form of a tab. The tab is arranged to be operatively connected to the brake linkage and points into the inner side of the trolley.

[0003] The vehicle can also have a joint piece. The joint piece is disclosed, for example, in EP 0 722 846 B1. The joint piece is located on the back side of the vehicle frame. Two joint pieces are used to support the beam on the one hand. The beam is inserted into the joint piece from above. In addition, two walls are provided, which are designed to support the wheels. The joint piece is part of an extruded profile, wherein the fixing area of ​​the joint piece is hollow. A space for receiving parts of the brake device is provided outside each fixing area between the wall and the wheel.

[0004] The storage area for luggage, merchandise and the like is formed by rods which are part of an extruded profile. The beams of the vehicle are also part of an extruded profile. Alternatively, tubes or other hollow profiles are conceivable.

[0005] Typically at least the joint pieces, as well as the rods and beams are also made of aluminium material.

[0006] In addition, the cart is usually equipped with a basket made of wire, which is used to store hand luggage or other small items. The basket is arranged on the inner side of the beam and preferably has an additional floor-like cover, which can be replaced.

[0007] Furthermore, EP 2 230 150 B1 describes a transport trolley with a front clamp. The trolley is equipped with the clamp and prevents boxes, bags or other objects from unintentionally sliding off. Summary of the invention

[0008] The object of the present invention is to provide an improved transport trolley and an improved basket.

[0009] The invention achieves the object by the features of the following technical solution. Thus, a stackable, manually movable transport vehicle is provided with a vehicle frame, wherein rollers are arranged on the vehicle frame, wherein the vehicle frame is provided with an upwardly protruding beam which carries a displacement device, wherein a brake can also be triggered by the displacement device, wherein the vehicle frame has a storage area for goods, luggage or the like, wherein an upper basket is provided, wherein the vehicle is also provided with at least one connecting piece which has a fastening area for carrying the beam, wherein two walls are provided on the fastening area, which walls form a space for the brake device, wherein the space is protected by an upper cover which has an opening for receiving the beam and surrounds the beam.

[0010] This ensures a simplified arrangement of the beam and furthermore enables a reduction in the aluminum profile used as beam by the additional stabilization. The two parts, beam and the placement area as parts of the vehicle frame, are preferably additionally welded to one another.

[0011] The brake device can be protected by a cover on top to prevent damage or contamination.

[0012] The cover can consist of plastic and can be arranged on the wall in a replaceable or stationary manner.

[0013] Furthermore, the cover can have a predominantly horizontal region and a slightly inclined region, wherein the opening for receiving the beam can preferably be arranged in the predominantly horizontal region. The cover thus provides a surface sufficient for receiving the beam. Furthermore, the shape of the cover is not disturbingly affected neither during stacking nor when pushing the vehicle.

[0014] Furthermore, it is conceivable that the triggering element is arranged on the underside of the rod of the storage area.

[0015] Two different types of triggering components can be used here. A triggering component can be provided, which enables the lifting of the front, identical, stacked vehicle. However, a triggering component can also be provided, which actuates the brake release device and releases the brake of the front vehicle. In both embodiments, the vehicles can be moved in a simple manner stacked in a row.

[0016] It has proven to be useful to arrange the brake release device on the inner wall so that it acts without interfering with the movement process.

[0017] Furthermore, the brake release device can have a flat region which is provided for arranging the brake release device on the inner wall. The inner wall has an opening in order to enable the brake device to interact with the brake release device.

[0018] Here, the brake release device can have a region extending into the interior of the vehicle, which is directly operatively connected to the triggering member for releasing the brake. Thus, it can be ensured that the brake can be easily released in the state where two or more vehicles are stacked.

[0019] Furthermore, the vehicle can be equipped with a tilting clamp in the front area.

[0020] The invention further achieves the object by means of the features of a further embodiment. Therefore, a basket for a transport vehicle is provided.

[0021] The basket can be manufactured as easily connectable elements that can be plugged into one another or clamped. The use of extruded aluminum profiles on wide side walls allows for low weight and flexible basket sizes as required. In addition, the use of signs and / or advertising is conceivable. The signs or advertising can be arranged in a replaceable manner, for example glued on.

[0022] The side walls made of plastic, preferably PP, allow for easy assembly, favorable production and, if necessary, rapid replacement.

[0023] In order to ensure stability, it has proven useful to provide at least one reinforcing rib in the side part made of plastic.

[0024] An open bottom part is provided, which reduces the material usage and thus the weight. The bottom part is provided, for example, by a plastic, a sheet material or a wire part. In addition, contamination of the basket can be prevented thereby.

[0025] The basket can be provided cost-effectively by means of this more simplified product type. Additional reinforcement elements can be omitted. Different materials can also be used, such as, in particular, aluminum and plastic.

[0026] In particular, the support beam can be additionally fixed and stabilized in the receptacles provided in the narrow side parts.

[0027] Preferably, the components of the basket and here in particular the side parts are additionally fixed by means of fixing elements.

[0028] A size of the basket in the range of 18 to 20 litres is advantageous and provides sufficient space for storing smaller items. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Figure 1A stackable and manually movable transport trolley 10 is shown, which has a frame 20. The frame 20 is equipped with a beam 24 that stands upright. The beam 24 carries a displacement device 30. The brake 90 can be released by pressing the displacement device 30 downward. The frame 20 has a storage area 22 for goods, luggage and / or the like. Rollers 80 are arranged on the frame 20. The transport trolley 10 shown has three rollers 80. Other numbers of rollers, for example four or five rollers, are conceivable.

[0047] The triggering element 40 accordingly lifts the rollers of the vehicle moving ahead, so that a train can be moved in a simple manner.

[0048] The basket 70 is arranged in the upper region. It receives the beam 24 and surrounds it. The beam 24 extends into the connecting piece 60, which receives the rollers 80 and surrounds the brake device 92. The fastening region 62 is provided in particular for carrying the beam 24. Two walls 63 are arranged on the fastening region 62, which form a space 64 for the brake device 92.

[0049] The space 64 is protected by an upper cover 65. The cover 64 has an opening 69 for receiving the beam 24. In addition, the opening 69 surrounds the beam 24. The cover 65 is preferably made of plastic and is arranged on or at the wall 63 in a replaceable or fixed 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 arranged in the mainly horizontal area 66.

[0050] The trigger member 40 is arranged on the lower side of the rod 28 of the storage area 22. The rod 28 is preferably manufactured as an aluminum profile, which may have Fig. 9 The cross section shown in FIG. . Compared to conventional aluminum profiles, a material saving in the range of about 20 to 40% can be achieved. In particular, the wall thickness is reduced from 3 mm to 2 mm, for example. In addition, an opening is provided for the recess 110 , which can receive the crash profile 100 . This further reduces the material usage. By Fig. 9 The geometry shown in can increase the drag moment, so that the wall thickness can be reduced accordingly. The reduced material usage can reduce the weight of the vehicle, so that the mobility of the vehicle can be improved in an advantageous manner. In addition, the manufacturing costs can be reduced.

[0051] In the region of the connection piece 60, a crash profile 100 is arranged in the lower region. An identical crash profile 100 is preferred, which is inserted into the recess 110. The crash profile 100 preferably ends in the region of the connection piece 60 and is arranged on the connection piece in a fixed position. Rivets are provided for this purpose. Plastic, for example PU, is provided as the material for the crash profile 100. For the entire vehicle 10, 10', a length of approximately 1600 mm of the crash profile 100 is used.

[0052] exist Figure 2 and 3 4 shows a trigger component 40. The trigger component is L-shaped. The trigger component has a core 42, which is provided with a notch 41 to save material. The notch 41 is quadrangular in shape. Other shapes are conceivable. In addition, a cover 43 is provided, which is preferably made of an elastic material, such as plastic. The cover 43 can be plugged onto the trigger component 40 and fixed in a replaceable manner. Easy replacement is possible.

[0053] Figure 4 A further embodiment of a transport trolley 10 ′ is shown. The transport trolley has a tilting clamp 50. In addition, a triggering component 44 is provided, which is designed to be able to be operatively connected to a brake release device 94, whereby the brake device 92 or brake 90 can be released. The triggering component 44 is also arranged in a fixed position on the lower side of the rod 28 of the storage area 22.

[0054] Figure 5a , b, c show the specific working modes of the brake release device 94 and the trigger component 44. Figure 5a In the embodiment of the present invention, the vehicle 10' is braked. The brake release device 94 is arranged on the inner wall 63a. 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 supported so that it can move. The opening 68 is provided as a guide device.

[0055] Figure 5b It is shown that the brake 90 is released, for example, 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 triggering element 44 for releasing the brake 90.

[0056] The triggering member 44 is equipped with a stop which limits the movement of the vehicle 10' behind. Figure 5c The stop acts directly on the region 98 extending into the interior of the vehicle 10 ′ and lifts the brake 90 via a lever mechanism, thereby releasing the brake 90 and allowing the vehicle 10 ′ to move.

[0057] Figure 6a The braked vehicle 10' is shown again. Figure 6b The brake is released.

[0058] Figure 7 A basket 70 is shown having two wide side parts 72 and two narrow side parts 74. Receptacles 76 for the beams 24 are provided in the narrow side parts 74. Preferably, the wide side parts 72 are manufactured from an extruded aluminum profile and the narrow side parts 74 are made from plastic.

[0059] Figure 8 The same basket 70 is shown, broken down into individual components. All parts are plugged or clamped to each other and preferably fastened by screws. The bottom part 77 is provided with an opening 78. The opposite wide side parts 72 can be made of the same aluminum profile or, as shown, different aluminum profiles.

[0060] As in Figures 10 to 13 As shown in FIG. 1 , the car 10 ′ has a flip clamp 50. For use, the flip clamp is opened to an almost vertical position. In this position, the clamp 50 protects the items on the car 10 ′ from falling.

[0061] The clip 50 may also be used in the first vehicle 10 .

[0062] The clamp 50 is arranged in the front area of ​​the vehicle 10 '. For this purpose, a device 52 for receiving the clamp 50 is provided in the front area of ​​the vehicle 10 ' between two rods 29 inside the storage area 22. The clamp 50 can also be arranged later if necessary. The device 52 makes it possible for the clamp 50 to be supported in a rotatable manner. Fig.10 Shows the usage status.

[0063] The area between the two rods 29 is as Fig.11 As can be seen, sufficient space is provided for arranging the device 52 for receiving the clamp 50. A replaceable or fixed arrangement can be selected. In particular, the holding area of ​​the front roller 80, which is also arranged between the two rods 29, but below the storage area 22, also provides sufficient space to arrange the device 52 for receiving the clamp 50. The holding area 54 of the device 52 provides a sufficient horizontal surface to arrange the device 52 permanently and / or replaceably on the upper side of the roller receptacle.

[0064] The two rods 29 also serve to fasten the device 52. Based on the preferably oval embodiment of the rods 29, in particular the inner wall of the rods 29 is used accordingly. The device 52 can be arranged permanently and / or replaceably on the inner side of the rods 29 in a simple manner.

[0065] As by Fig.12 As can be seen, the two middle rods 29 are spaced apart so that the clip 50 can be securely held between the two rods 29 in the unused position. The clip 50 has a slight bend, see for example Fig.14The bend is preferably designed in such a way that the angled area is not above the upper edge of the rod 29 in the non-use state. As a result, the clamp 50 does not interfere with its function even when the storage area 22 of the vehicle 10' is loaded. Due to the slight bend, the lower area of ​​the clamp 50 acts like a stop. The lower area of ​​the clamp 50 can move until it strikes the holding area 54 of the device 52. As a result, the holding area 54 of the device 52 ultimately forms a stop for the clamp 50. This is caused by Fig.15 Conclude.

[0066] This prevents the clip 50 from reaching deeper into the vehicle interior or, in the worst case, from rubbing against the ground. The arrangement between the two rods 29 also provides a guide for the clip 50. Slippage can be avoided. The possibility of the clip 50 taking up an incorrect position can also be ruled out.

[0067] exist Fig.12 , 13 shows the unused position of the clamp 50. The clamp is supported between two rods 29. Due to the slight bend in the upper region of the clamp 50, the clamp is supported in the unused position in the upper region partially below the storage area 22 and below the rods 29. When identical carts 10, 10' are stacked, the clamp functions without interfering.

[0068] The function of the tilting clamp 50 is designed in this case so that the spring 56 arranged inside the shaft is preloaded with a torsion force. This achieves the desired effect, namely that there is always a clamp 50 standing up. When stacking identical vehicles 10, 10', the clamp 50 can then be easily tilted down in the direction of the center of the vehicle against the resistance of the spring 56. When the vehicle 10, 10' is removed from a row of identical vehicles 10, 10', the clamp 50 is then tilted back into the use position of the clamp due to the pre-set spring 56. Due to the described structure, there is no longer a pinching point when the clamp 50 is tilted upward.

[0069] The holding area 54 can be placed on a conventional frame of a vehicle 10, 10' in a simple manner. A horizontal embodiment of the holding area 54 has proven to be advantageous. Perforations are preferably provided here. The perforations are used to receive the holding device 52 of the clip 50 on the frame 20 of the vehicle 10', for example by means of a screw connection or a rivet connection. In addition to the holding area 54, a receiving portion and a protective device 58 for a spring 56 are also provided. The receiving portion 58 is a cylindrical cover for the spring 56, which provides sufficient protection for the spring 56. The holding area 54 is preferably constructed in a square shape and is fixedly arranged on the receiving portion 58.

[0070] Furthermore, an additional fastening device 59 is provided, which likewise serves to ensure a permanent and / or positionally fixed attachment of the device 52 to the frame 20 or to the roller receptacle.

[0071] As also seen Fig.14 , 15 and 16, the clamp 50 is made of round wire. The clamp is fixedly arranged on the receiving portion 58 and acts directly with the spring 56.

[0072] The device 52 is thus preferably formed at least from a holding region 54 , a receptacle 58 for a spring 56 , which is arranged on the device 52 , and a fastening device 59 which provides for arranging the device on the frame 20 of the vehicle 10 , 10 ′.

[0073] In addition, as Figures 14 to 16 As can be seen, two semicircular bends 53 are provided, which have circular through-holes 55. The two opposite through-holes 55 receive the receptacles 58 of the springs 56. The opposite through-holes 55 are of the same size and are designed so that the cylindrical receptacles 58 for the springs 56 can be received and the rotational movement of the receptacles 58 is ensured. The bends 53 also allow for an additional attachment to the rod 29.

[0074] As by Fig.16 As can be seen, the spring 56 is arranged on the end cap 51, which is operatively connected to the receptacle 58. The cylindrical pin 57 fixes the end cap 51 to the spring 56 in the receptacle 58 for the spring 56. For this purpose, the end cap 51 has a corresponding opening. In addition, the receptacle 58 also has a corresponding opening, which is also provided for inserting the pin 57 to fix the spring 56. The size of the pin 57, that is, the length and the cross section, are different here.
