Definitions

  • Retaining device for the wheels of a vehicle
  • the subject of the innovation is a holding device for the wheels of vehicles with the features of claim 1.
  • EP-B 0452519 and EP-0548633 show a hook that holds the underrun protection of the vehicle.
  • the disadvantage of these systems is that not all vehicles have an underrun protection or the space that is required to turn the hook up is too small.
  • EP-A 0609049 has the disadvantage that weather influences such as ice and snow can easily impair the effectiveness of the device.
  • EP-A 0580415 has the disadvantage that it has to be installed in the ground, which entails high costs.
  • the aim of the innovation is to create a system that securely holds the vehicles in place, that does not require an expensive drive or foundation. This goal is achieved by the innovation with the features of claim 1.
  • the device consists of two support plates standing vertically next to the vehicle wheels, which have a recess in which two pipes connecting the support plates roll, which are connected to one another by elastic elements.
  • the rearmost wheels of a vehicle approaching the ramp backwards roll over the pipe facing away from the ramp, which is initially on the ground, and then press against the second pipe.
  • This second tube now rolls in front of the wheels in the direction of the ramp and takes the first tube behind the wheels in a rolling manner by means of the elastic elements that are more or less tensioned depending on the wheel diameter.
  • This first tube is connected on both sides to a continuous endless chain that can be locked, or lifting the lower support plate part leads to locking.
  • the lock is activated and the two rearmost wheels are now held.
  • the lock is released again, the vehicle drives away and pushes the pipe that is turned away from the ramp in front of it again, the second pipe is carried along again by the elastic elements.
  • the first tube is in the rest position on the ground, the vehicle wheels drive over it again and the vehicle can leave the ramp.
  • the most diverse wheel diameters can be locked by a suitable choice of the elastic elements. Since the entire system is mounted on plates on which the wheels to be locked are located, these hold the entire device in place due to its own weight, expensive anchoring and foundations are unnecessary.
  • the fastening of the elastic elements to the tube facing the ramp can be easily released by hand. If snow has to be cleared, one loosens these fastenings and pushes this pipe towards the ramp until it is also on the ground. Now the snow plow can work undisturbed.
  • the opening in the steel plate facing the ramp is designed in such a way that a vehicle that goes beyond the device with the rearmost wheel and hits the pipe turned away from the ramp with the next wheel also rolls it onto the floor of the device and thus prevents damage .
  • FIG. 1 shows an oblique view with the vehicle just starting
  • FIG. 2 shows an oblique view with the locked vehicle standing on the ramp
  • FIG. 3 shows a section along A-A of Figure 4
  • FIG. 4 shows a side view of the right plate with an endless chain
  • Figures 11, 12 and 13 show a special embodiment of the tube (8)
  • FIG. 14 shows an oblique view of a preferred embodiment
  • FIG. 15 shows a section along the line AA from FIG. 16, FIG. 16 the front piece of the preferred embodiment when starting off,
  • FIG. 17 shows the preferred embodiment before locking
  • FIG. 18 the preferred embodiment in the locked position
  • Figure 19 shows a detail of the guidance of the preferred embodiment
  • Figure 20 shows a clamping detail of the preferred embodiment.
  • FIG. 1 shows the rearmost wheels (4) just moving onto the device of a vehicle approaching backwards on ramp (1) with a possibly installed dock leveler (2) and buffers (3).
  • the holding device is symmetrical about axis x-x, that is, it consists of a left part, a right part symmetrical to it, which are connected to one another by connecting strips (16), and the tubes (8) and (9).
  • Each of the symmetrical parts consists of a base plate (5), which is chosen so wide that the vehicle wheels always drive over this base plate, and a vertical support plate (6) arranged on this base plate, which has a slot (7).
  • This slot (7) - see Figure 4 - begins on the base plate (5) rises at an angle () and merges with a circular arc into a line running parallel to the base plate (5). The possible working area is only determined by the length of this line.
  • the top line of the slot runs through on the side facing the ramp, while the bottom line again runs over a circular arc and obliquely at an angle () to the base plate (5) leads.
  • Each of these symmetrical parts further comprises a continuous endless chain (13) which is connected to the tube (9) and runs over chain wheels (14) and can be locked by means of a suitable lock (15).
  • the device has a front tube facing the ramp and located in the horizontal region of the slots (7)
  • the front tube (8) and the rear tube (9) are connected to one another on both sides by elastic means (10), the connection to the front tube (8) being detachable by hand.
  • the arm (12) is designed to prevent damage to the device when the vehicle wants to drive away when the endless chain is locked, designed as a predetermined breaking point, so that the pipe (9) can be moved away from the ramp by the moving vehicle if necessary.
  • Figure 2 shows the same device with wheels (4) in the locked state.
  • Figure 3 shows that the endless chain is preferably a round steel chain.
  • the front tube (8) and the rear tube (9) each consist of an axis (50), the tubes (8) or (9) themselves, conically shaped rollers (53), connecting tube (52) for the connecting tension element (10 ) and connecting tube (51) which is connected to the endless chain (13) in the rear tube (9) via the arm (12).
  • FIGS. 5, 6 and 7 show how the front tube (8) and rear tube (9) and the elastic element (10) behave, when a small diameter wheel (4) drives in or out of the device.
  • Figures 8, 9 and 10 show the same situation with a large diameter wheel.
  • FIGS. 11, 12 and 13 Since the space up to the vehicle floor on the rear is often very small, a preferred embodiment of the front tube (8) is proposed, which is shown in FIGS. 11, 12 and 13.
  • the axis (50) in the vicinity of the conically shaped rollers (53) is cut through, two spacers (8c) generating the height (H) are inserted, on which the operating axis (8b) to which can rotate the operating tube (8a), is preferably releasably attached.
  • the rotary movement of the operating axis (8b) with the operating tube (8a) about the axis (50) can be seen from FIGS. 11 and 12 and is caused by the force (P) applied by the vehicle wheel.
  • the diameter of the operating axis (8b) and the operating tube (8a) can be significantly smaller than the diameter of the axis (50) and the rollers (51, 52, 53).
  • the operating axis (8b) is attached to the spacers (8c) in such a way that this connection can easily be released by hand without the use of tools.
  • the height of the slot (7) is variable and at least one of the surfaces of the support plate parts (6a, 6b) forming the slot has circular cutouts that look like sawtooth.
  • the previously described support plates (6) consist of an upper plate part (6a) which is firmly connected on both sides to the guides (6c), a lower plate part (6b) which has a running rail (6f) and not through this
  • the means shown is adjustable in height and runs when it is raised in the guides (6c), and the connecting piece (6d) connected to the base plate (5), in which the guides (6c) are slidably mounted, the force of the springs (6e) being shifted must be overcome.
  • FIG. 14 shows one side of this preferred embodiment, lifting elements and the vehicle wheel not being shown.
  • the rollers (8) and (9) run over rollers (53) on the spring rail (6f) which is resiliently mounted on the lower support plate (6b) and are connected to one another in the connecting tubes (52) via a tension element (10).
  • Figure 19 shows the detail of how the roller (53) rolls over the rail (6f), which is fastened to the abutment (6h) of the lower support plate (6b) via the spring element (6g).
  • a guide (50a) with a roller or sliding element (50b) is attached to the axis (50).
  • the arm (61) is used to attach the lifting element (HU), not shown.
  • FIGS. 15 and 16 show how the tubes (8) and (9) are positioned when the vehicle starts up.
  • the springs (6g) hold the running rail (6f) up and allow rolling the rollers (53).
  • the spring force of the springs (6g) must be so great that the track (6f) is not pressed in when the vehicle is started.
  • the guide (6c) is mounted on the supports (6d).
  • Spring elements (6e) allow the guides (6c) to move horizontally. This is necessary for locking, since only then can the tube (9) be securely clamped by the support plates (6a) and (6b) in every vehicle position.
  • Figure 17 shows the wheel (4) when the locking process begins.
  • the lower support plate is raised in the direction of the arrow (K), the rollers (8) and (9) roll up over the wheel (4) and the tension element (10) is stretched.
  • Figure 18 shows the position when the tube (9) is clamped and the vehicle is secured.
  • the circular recesses in the upper and lower support plate (6a, 6b) are designed so that their diameter is slightly smaller than the diameter of the tube (9). This creates a gap (d) when the pipe (9) is clamped, which prevents pinching between the upper (6a) and lower support plate (6b).
  • Figure 20 shows a design of the preferred embodiment, in which only the upper support plate has circular recesses, while the lower support plate (6b) is designed as a smooth running rail (6f).
