Description

The Invention relates to a pallet for the transport of trolleys, which at least laterally for receiving the trolley wheels one-sided limited raceways, which in the insertion direction on the back are provided with an insertion limit.

Pallets for the transport of so-called trolleys have been known for some time. To this is exemplary on the WO 2009/090309 A1 as well as the DE 20 2006 007 202 U1 directed. These constructions have in common that the pallet consists of a welded construction, in particular of different welded together sheet metal components and has for receiving or for inserting the rolling carriage wheels corresponding raceways. In particular in the field of these tracks, these pallets consist of correspondingly bent sheet metal components. Between these tracks, these pallets form a kind of tunnel, in which, for example, a low-lift truck can be retracted with his forks. By subsequently raising the forks, the pallet is thus lifted from the ground and can be transported accordingly for loading accordingly on the ground by means of Niederhubwagens.

At the subject of WO 2009/090309 A1 is a backup plate provided to secure the recorded trolley, which is arranged in the region of the tunnel. If two trolleys are to be taken in succession on the raceways, two such fuses are provided in this tunnel area, each of the fuses being assigned to one of the trolleys. The securing plate is here formed a sheet metal component and pivotable about a parallel to the raceways arranged pivot axis. Thus, this backup plate can be swung out of a neutral, approximately horizontal position with its free end up. In this free end region, this securing plate has a receiving groove which can be correspondingly brought into positive engagement with a component of the trolley. For this purpose, however, it is necessary to provide the trolley with a transverse strut or a crosspiece, so that the securing plate can be brought into positive engagement with its receiving groove with the trolley. An advantage of this construction is that each pallet truck can be secured individually. For actuating the bearing shaft of these locking plates, a hand lever is provided in an end region, which is rotatably connected to the bearing shaft of the locking plates. In order to perform a pivoting movement of this hand lever, it must first be "unlocked" in the axial direction to then drive the bearing shaft of the locking plates rotating. This is somewhat complicated, especially when the pallet is fully loaded, since, in particular, this hand lever is inevitably arranged in the area of the substrate and is thus difficult to access. In particular, the axial movement can only be performed by hand, so that the operator can handle this locking device only in kneeling or crouching working position. Furthermore, it is imperative that the trolley, as already mentioned above, a corresponding component, such as a cross bar or a cross bar, to be able to be brought into engagement with the receiving groove of the respectively associated locking plate.

At the subject of DE 20 2006 007 202 U1 a similar principle is applied. However, there is a pivot lever in the free, the insertion limit opposite end portion of the pallet manually pivoted into the track of the last recorded trolley. This pallet is, so the embodiment, for receiving a total of three successively arranged trolley, so that only the "last" trolley can be secured by this construction. If the number of rolling carriages to be accommodated is reduced, that is, if, for example, only two or only one carriage are received in succession, then these carriages can not be secured in their freedom of movement along the raceways for the rolling cart wheels. It should be noted that the two aforementioned constructions of pallets have in common that the raceways for the rolling cart wheels are provided on one side with a stop as insertion limit. Anyway, at the DE 20 2006 007 202 U1 is a backup of the individual trolleys not possible. Furthermore, the locking and unlocking can be made only in a kneeling or crouched working position of the staff, since no further easily accessible actuators are provided here.

Accordingly, lies The invention is based on the object, a range of the generic Art to design such that the recorded trolley in a simple Way can be secured.

The object is achieved in that at least one adjustable blocking device is provided transversely to the insertion direction in the region of at least one of the raceways, which is engageable with a component of the trolley for locking the respective trolley into engagement and that the respective blocking device is associated with an adjusting device, which is guided in the insertion direction of a trolley from a neutral starting position to an active end position adjustable in a guide track of the pallet and, in that the blocking device engages with the adjusting device via a slide guide effecting the adjusting movement of the blocking device and that a releasable locking device is provided by which the active end position of the adjusting device can be fixed.

By The inventive design is every trolley alone in his on the raceways Position securable. For this purpose, a blocking device is provided, which can be brought into engagement with a component of the trolley. This Blocking device is associated with an adjusting device, which in the insertion direction of the trolley from a neutral starting position in an active end position adjustable in a Füh of the track Pallet is guided. In particular, the backup of the trolley can by simply "pushing" this Stellvorrichtung be made. For this it is not necessary that the operator moves into a squat or kneeling position, because this actuator can also be operated with the foot is. Furthermore, this adjusting device is connected to the blocking device a link guide in conjunction, so that the adjusting movement of Actuator an adjusting movement of the blocking device across causes the insertion direction of the trolley. It moves the Blocking device from a neutral position transverse to the insertion direction in the range of the career of the rolling cart wheels. It will be the trolley wheels or their "bearing blocks" against blocked the insertion direction, since the blocking device this engages behind the insertion direction. Because every trolley one Such blocking device based on the respectively associated Track is assigned, can thus by a single actuator movement the adjusting device a simultaneous adjustment of the blocking devices be effected so that each trolley is on its own taken on the pallet can be secured.

Further advantageous embodiments are the further subclaims removable.

So can be provided according to claim 2, that the Adjusting device is plate-shaped and in her the insertion limit opposite end a transversely to the actuator up or down angled Actuating web has, and that the adjusting device in the end region of the actuating bar at least a first Breakthrough, with which a top side on the guideway projecting locking lug in the active end position of the adjusting device can be brought into engagement. This embodiment is in particular the active end position of the actuator in a simple manner secured the catch. Through the angled actuating bridge In particular, the risk of injury is significantly reduced. Furthermore is the operation, in particular for solving the Actuator, relieved.

Further can be provided according to claim 3, that the first breakthrough of the actuator associated with a second breakthrough is, which in the direction of insertion of a trolley behind the first Breakthrough is arranged in the adjusting device, and in which the locking lug of the guideway in the neutral starting position intervenes. By this configuration, in particular, the vertical position the actuator in both the active end position as well in the neutral starting position always identical, so that no Disabilities when inserting or pushing out a trolley may occur.

Further may be provided according to claim 4, that the Adjusting device at least in the end region of the first breakthrough is resilient, and that the adjusting device of the guideway lifted and thus with their first breakthrough with the latch can be disengaged and in their neutral Starting position is reset. This embodiment allows extremely easy operation the adjusting device, so that both the lock and the Unlocking the trolley is easy to carry out.

Equally advantageous is the embodiment according to claim 5, according to which the latching lug forms a latching stop in the insertion direction and a ramp in the opposite direction to the insertion direction. D. h. That when locking the actuator this slides with a located between the two breakthroughs securing ridge on the ramp of the locking lug until the first breakthrough with the locking lug or its latching stop overlaps. Then, the actuator moves with its first breakthrough again vertically downwards, so that it engages with this latching stop positively. Thus, the locking of the adjusting device and thus the blocking device is secured. By simply raising the adjusting device in the region of its two openings thus this backup can be canceled by the latch again. The return movement can be effected by a tension spring, which is effective between the actuator and the guideway for the actuator of the pallet. It can be seen that locking of the adjusting device can be carried out in a simple manner, in particular, by means of this special design of the latching lug with its latching stop and its ramp. For this purpose, it is only necessary to move the adjusting device in the direction of insertion, so that it automatically engages with its first breakthrough on the locking stop of the locking lug. By simply lifting the adjusting device with her first breakthrough with the latch or its latching stop are disengaged, so that by the spring force described, the adjusting device moves back to its neutral starting position. Thus, in particular a simple operability is achieved, since the adjusting device can be operated in a simple manner with the foot, so that it is not necessary for the operator to assume a kneeling or squatting position for locking or unlocking. In particular, this advantageous operability also ensures that during the locking the operator can safely monitor the erected trolley.

Further may be provided according to claim 6, that the Blocking device of two or more plate-shaped Bar plates consists, which at the same time by the adjusting device be assigned to their assigned career of the rolling cart wheels and that one of the latch plates with a first, completely up to the insertion limit inserted trolley and the other Lock plate with a second, zoom up to the first trolley pushed trolley in a form-fitting engageable is. This embodiment causes in particular an extremely secure locking of the trolley (s). The latch plates are doing transversely to the insertion direction in the career of the rolling cart wheels pushed in, so that about these dolly wheels or the bearing blocks of each trolley are secured individually can. Should more than two trolleys in the direction of insertion behind each other are recorded on the pallet, so are accordingly several this latch plates, according to the number of male Trolley to provide. There is no latching with the trolley An absolutely secure locking of each trolley is possible. By far ren make these latch plates an extremely simple backup, as this is extremely simple can be produced.

Further may be provided according to claim 7, that each the latch plates is arranged above the respective track and that the respective locking plate with one of the rolling wheels or Bearing blocks one of the rolling wheels of each associated trolley is engageable. This embodiment allows an absolutely secure locking of the respective Trolley, as the latch plates this in the range of his dolly wheels or behind the bearing blocks of the trolley wheels safely. On the other hand, an independent release is also not possible due to the provided safety catch. Due to the spring-loaded recoverability of the actuator On the other hand, it is also recognizable to the operator at any time. whether there is a lock or not. Because of the spring-loaded Provision is made that when not engaged a full return movement through the Return spring in the starting position of the adjusting device is effected. Thus, the trolleys are not secured, which of the operator is easily detected. Is however the adjusting device locked, so it is also ensured that the latch plate the respective trolley wheel or its bearing block engages behind, so that It is also ensured that the corresponding trolley securely locked is. This is not necessary for the operator to check if the fuse is actually was done completely by, for example visually checked whether the latch plates actually in an appropriate arrangement in the career of the rolling cart wheels have been pushed. This is inevitable after snapping the case. In a similar way finds the release This locking takes place by simply the adjusting device, such as already described above, is raised so that the locking connection is lifted to the guideway and the spring-loaded Actuator inevitably back to its neutral starting position emotional.

Accordingly may be further provided according to claim 8, that for resetting the actuator from its active End position in their neutral starting position one between the Actuator and the guideway effective tension spring is provided. This tension spring causes, as already described above, a forced unlocking, as soon as the locking connection between lifted the actuator and the pallet or the guideway is.

Of Further may be provided according to claim 9, that the adjusting device in their respective guideway secured by securing webs, which is the guideway cover each upper side at least partially. The design according to claim 9 causes on the one hand a stabilization the entire range and on the other hand a secure captive Holder of the adjustable adjusting device in the respectively associated Guideway.

It can further be provided according to claim 10, that the pallet is designed in size such that a total of four trolleys are receivable, and that the raceways and the guideways and thus the entire range consist of a single, multiple bent sheet metal component or exists. Through this Ausges planning the pallet receives a standard size with appropriate size of the trolley and is extremely simple and inexpensive to produce due to the design as a sheet metal component. Preferably, two raceways are always assigned in pairs to accommodate the trolley. In this case, two pairs of raceways can be provided side by side to accommodate the four trolleys, so that in each case a pair of raceways receives two trolleys in a row. the pairs of tracks are arranged side by side.

following is the example of the invention by way of example with reference to the drawing explained. It shows:

2 an enlarged section II of the range 1 ;

3 an enlarged section III of the range 1 ;

4 an enlarged section IV of the end portion of an adjusting device of the range 1 ;

5 a section V of the second actuator of the pallet 1 ;

6 a section VI-VI 5 by the latching device of the second setting device;

7 a partial perspective view of the palette 1 with a recorded trolley.

1 shows a perspective view of a pallet 1 which is formed in the present embodiment as a sheet metal component. This palette 1 has four tracks 2 . 3 . 4 and 5 on, with the raceways 2 and 3 and the tracks 4 and 5 are assigned to each other in pairs. These careers 2 . 3 respectively. 4 . 5 serve to accommodate the trolley wheels of a trolley.

How farther 1 It can be seen that these tracks are 2 . 3 and 4 . 5 on the back by a - preferably common - boundary wall 6 limited, which serves as a stop when inserting a trolley. Between the raceways 2 and 3 respectively. 4 and 5 forms the pallet 1 each a kind of "tunnel" 7 respectively. 8th in which, for example, the forks of a lift truck or a forklift are retractable. Accordingly, the pallet forms between the raceways 2 and 3 respectively. 4 and 5 a vertically elevated guideway 9 respectively. 10 , in each of which an adjusting device 11 respectively. 12 in the direction of the double arrow 13 is added adjustable. Here is the actuator 11 against the arrow 14 adjusted shown in their neutral starting position. The arrow direction 14 represents the insertion direction for a trolley, which from right to left either in the raceways 2 . 3 respectively. 4 . 5 in the palette 1 can be inserted.

The adjusting device 12 is in 1 in their direction of insertion of the arrow 14 adjusted, active end position shown.

Furthermore, it is off 1 recognizable that the adjusting devices 11 and 12 are plate-shaped and approximately over the entire length of the respective associated guideway 9 respectively. 10 and thus the pallet 1 extend. For limited sliding guide the respective actuator 11 respectively. 12 in the respective associated guideway 9 respectively. 10 have the adjusting devices 11 and 12 each guide slots 15 . 16 respectively. 17 . 18 into which corresponding guide pin 19 . 20 respectively. 21 . 22 intervention.

Through these guide pins 19 . 20 respectively. 21 and 22 are the two adjusting devices 11 and 12 captive in the associated guideway 9 respectively. 10 held displaceable.

Next is out 1 suggestively recognizable that the adjusting devices 11 and 12 each with a tension spring 23 respectively. 24 are provided, which corresponding tensile forces against the direction of insertion of the arrow 14 on the respective adjusting device 11 respectively. 12 muster. By these tension springs 23 and 24 Thus, restoring forces against the arrow 14 on the respective adjusting devices 11 respectively. 12 causes.

Next, the two adjusting devices 11 and 12 in its middle area setting-like adjusting slots 25 . 26 on, which at least partially obliquely to the direction of insertion of the arrow 14 run and in the respective adjusting device 11 respectively. 12 are arranged. In these adjusting slots 25 . 26 respectively. 27 . 28 each engages a setting pin 29 . 30 . 31 respectively. 32 one, each fixedly each with a locking plate serving as a blocking device 33 . 34 . 35 respectively. 36 keep in touch. The adjusting slots 25 . 26 . 27 and 28 form with the respectively associated adjusting pin 29 . 30 . 31 and 32 each type of slotted guide, so that in an adjusting movement of the adjusting devices 11 respectively. 12 in the direction of the double arrow 13 an adjusting movement of the locking plates 33 . 34 . 35 and 36 is effected. These latch plates move 33 to 35 during the adjusting movements of the adjusting devices 11 and 12 in the direction of the double arrow 37 transverse to the guideways 9 respectively. 10 ,

In the neutral starting position, as this for the actuator 11 is shown, are thus the associated latch plates 33 and 34 in her out of the running track 2 withdrawn position. In the active end position, as this for the actuator 12 is shown, however, are the latch plates 35 and 36 in one of the careers 5 protruding end position.

Thus, it can be seen that by an adjusting movement of the adjusting device 11 respectively. 12 in the direction of the double arrow 13 the two respectively associated latch plates 33 . 34 respectively. 35 . 36 together an adjusting movement in the direction of the double arrow 37 move back from a neutral, non-blocking position to an active blocking position.

For fixing, in particular the active end position of the respective adjusting device 11 respectively. 12 , In the present embodiment, in each case a detent 38 respectively. 39 provided, which in the active position, as this for the adjusting device 12 is shown in a first breakthrough 40 intervenes.

In the inactive position, as this for the actuator 11 is shown, the associated Rastna se 38 with a first breakthrough 41 the adjusting device 11 not engaged.

This first breakthrough 40 respectively. 41 is adjacent in the direction of the arrow 14 a second breakthrough 42 respectively. 43 provided, in which the respective locking lug 38 respectively. 39 in the neutral starting position of the respectively associated adjusting device 11 respectively. 12 intervenes. Through this second breakthrough 42 respectively. 43 is achieved that the respective spring-elastic adjusting device 11 respectively. 12 just in the respective guideway 9 respectively. 10 also runs in its neutral starting position, as for the adjusting device 11 out 1 is apparent.

It can also be seen that each of the adjusting devices 11 and 12 in their front right end, so the boundary wall 6 opposite, a vertically upwardly bent actuating web 44 respectively. 45 by which the handling or adjustment of the respective adjusting device 11 respectively. 12 is relieved. In particular, each of the adjusting devices 11 and 12 be moved with the foot from the neutral starting position to the active end position.

3 shows an enlarged section II of the pallet 1 , from which in particular the arrangement of the tension spring 23 as well as the guide slot 15 together with the associated guide pin 19 relative to the actuator 11 is apparent. The storage and arrangement of these components is for the actuator 12 identical, so that the following description also applies to the adjusting device 12 to read.

The adjusting device 11 forms for receiving the tension spring 23 a longitudinal breakthrough 50 , Below this breakthrough is in 2 a part of the career 9 recognizable, which has a vertically upwardly directed tow hook 51 forms. In the tow hook 51 is the mainspring 23 hung with her one end. The other end of the tension spring 23 stands with a through hole 52 with the adjusting device 11 in train connection, this through-hole 52 in axial extension to the breakthrough 50 in the actuator 11 is arranged.

By this tension spring 23 thus becomes a restoring force against the arrow 14 applied so that the adjusting device 11 by this tension spring 23 in the in 2 shown neutral initial position is held. Accordingly, there is the guide pin 19 in the left, rear end region of the guide groove 15 , To lift the actuator 11 out of the guideway 9 to prevent is on the guide pin 19 a sliding washer 53 intended. Furthermore, in 2 two more safety bars 54 and 55 recognizable, by which on the one hand the adjusting device 11 additionally in the guideway 9 is secured. On the other hand, by these securing webs 54 and 55 the pallet 1 in the area of this guideway 9 additionally stabilized.

Next is out 2 It can be seen that the illustrated neutral starting position of the adjusting device 11 through the axial length of the guide slot 15 (and also through the guide slot 16 out 1 ) is defined.

3 shows an enlarged section III of the pallet 1 out 1 in the area of the adjusting slots 25 and 26 , The following description is corresponding to the mirror symmetry obliquely to the adjusting slots 25 and 26 extending adjusting slots 27 and 28 the adjusting device 12 out 1 to read.

It can be seen that the two adjusting slots 25 and 26 obliquely inclined to the insertion direction of the arrow 14 and thus obliquely inclined to the direction of the double arrow 13 the adjusting device 11 run. Furthermore, it is off 3 another safety bar 56 recognizable. In the two adjusting slots 25 and 26 attacks, as already 1 mentioned, one adjusting pin each 29 respectively. 30 one. On this pin 29 and 30 is in turn a sliding washer 57 respectively. 58 provided so that the adjusting device 11 with their slots 25 and 26 with the associated adjusting pin 29 and 30 can not be disengaged.

Will now the actuator 11 against the arrow 14 moved, so the two adjusting pins 29 and 30 due to the oblique course of the associated adjusting slots 25 and 26 in the direction of the arrow 59 emotional. These adjusting pins are each stationary with the associated latch plate 33 respectively. 34 in the direction of the double arrow 37 adjustable in the pallet 1 are guided. Accordingly, due to the fixed connection, the adjusting pins 29 and 30 the respective associated latch plate 33 respectively. 34 the two latch plates 33 and 34 in an adjusting movement of the adjusting device 11 against the arrow 14 also an adjusting movement in the direction of the arrow 59 out.

This will get the two latch plates 33 and 34 in the field of career 2 ( 1 ), so that they can be brought into engagement with a trolley, in particular with a trolley wheel or with the bearing block of a trolley wheel. Thus, this is in the area, for example, between the latch plate 33 and the boundary wall 6 located trolley fixed on the pallet 1 fixed. The second latch plate 34 can be brought into engagement with a second trolley, which is located in the front region of the pallet. Thus, by the latch plates 33 and 34 each one on the pallet 1 or on the raceways 2 . 3 securely located separately.

Next shows 4 an enlarged section IV 1 in which the front end region of the adjusting device 11 is shown in its neutral starting position. In 4 is in particular also the vertically upwardly bent actuating web 44 recognizable. It can also be seen that in the area of the guideway 9 the upwardly projecting latch 38 another safety bar 60 located.

Next is out 4 recognizable that the catch 38 in the neutral starting position of the adjusting device 11 in the second breakthrough 43 the adjusting device 11 protrudes. The first breakthrough 41 is in this initial position of the actuator 11 out of the running track 9 , Will now the actuator 11 in the direction of the arrow 14 moved manually, so skips between the first breakthrough 41 and the second breakthrough 43 provided latching web 61 the catch 38 until the adjusting device 11 with her first breakthrough 41 latching with the catch 38 engaged.

This then reached active end position shows 5 for the second actuator 12 , It can be seen that the second breakthrough 43 in the direction of the arrow 14 has moved to the left and thus no longer with the latch 39 the second guideway 10 engaged. The first breakthrough 40 was adjusted so far that the catch 39 protrudes into this. Also in the area of this latch 39 is another security bridge 62 intended. Next is out 5 also the vertically upwardly bent actuating bar 45 the adjusting device 12 recognizable.

Like from the 4 and 5 it can be seen, the adjusting devices 11 and 12 identically formed, wherein the adjusting slots 25 and 26 respectively. 27 and 28 each mirror-symmetrically inclined to the longitudinal extent of the pallet 1 in the adjusting devices 11 and 12 are arranged. Thus, the two latch plates 33 and 34 on the one hand, upon activation of the adjusting device 11 in the direction of the arrow 59 in the area of the trajectory 2 moves while the latch plates 35 and 36 against the arrow 59 in the area of the guideway 5 be moved laterally outwards. This is in principle also off 1 recognizable.

6 shows a section VI-VI 5 , In this sectional view is the adjusting device 12 in her vertically upwardly bent actuating web 45 recognizable bar. Because this actuator 12 is in its active end position, the catch engages 39 according to the breakthrough 40 the adjusting device 12 one. It is off 6 it can be seen that this catch 39 to the right side a kind of ramp 63 forms, so when activating the actuator 12 in the direction of the arrow 14 which is between the two breakthroughs 40 and 42 located latching web 61 on this ramp 63 slips on, then into the in 6 to get shown position. In this position, the locking nose engages behind 39 this detent 61 with one in the breakthrough 40 protruding stop 64 , Next is out 6 still the securing bar 62 recognizable.

It is easy to imagine that by simply lifting the adjusting device 12 in the end of their actuating bar 45 in the direction of the arrow 65 the adjusting device 12 with her detent 61 with the catch 39 disengaged. Due to the spring force of the tension spring 24 out 1 Thus, after the latch 39 with the breakthrough 40 or the detent web 61 has been disengaged, an automatic return of the actuator 12 against the arrow 14 brought into their neutral starting position.

It can be seen that the pallet according to the invention 1 with its two adjusting devices 11 and 12 and the associated latch plates 33 . 34 respectively. 35 . 36 an extremely simple locking of one or more on the pallet 1 located trolley allowed.

This shows 7 a partial view of the pallet 1 in the area of their two careers 2 . 3 or in the area of the rear boundary wall 6 , On the pallet 1 Here is an example of a trolley 70 set up, which with his trolley wheels 71 on the one hand into the career 2 and with his trolley wheels 72 on the other hand into the career 3 is inserted. In 7 is the career path 3 only indicated by the Beugzeichenlinie. From the wheels 72 There are also two available, from but which only the front one is recognizable.

The trolley 70 is located in the rear end area of the pallet 1 and stands with his left trolley wheels 71 and 72 (not visible) on the boundary wall 6 at. Now should this trolley 70 in this position on the pallet 1 be secured, so now is the actuator 11 in the direction of the arrow 14 to move. This can be done, for example, by "counter-pressing" with the foot against the actuating bar 44 out 4 happen. During this adjusting movement, the two locking plates 33 and 34 simultaneously in the direction of the arrow 59 due to the engagement of the two adjusting pins 29 and 30 with the two adjusting slots 25 and 26 adjusted. At the end of the adjusting movement get the latch plates 33 and 34 in the in 7 shown in phantom lines locking position 73 respectively. 74 , It is in this bar position, as from 7 it can be seen, the right roller wheel 71 or its bearing block 75 blocked. This is the position of the trolley 70 defined and immovable on the pallet 1 between the latch plate 33 and the rear boundary wall 6 established.

Should several (two) trolleys 70 are recorded, so are first the latch plates 33 and 34 by Verstel development of the actuator 11 in their neutral starting position opposite to the arrow 14 in the in 7 shown to bring back position. Subsequently, a second trolley up to the in 7 illustrated trolley 70 be inserted into the pallet. If this second trolley is fully inserted into the pallet, the adjusting device 11 turn against the arrow 14 pressed, leaving the second latch plate 34 the left, in the running track 2 located rolling cart or its bearing block of the second trolley engages behind, so that this second trolley on the pallet 1 is securely fixed.

It can be seen that by the inventive design of the pallet 1 , In the present embodiment, a total of four trolleys can be secured in a simple manner.
