Definitions

  • the invention relates to a movable parking plate for parking motor vehicles with a drive for moving the parking plate, which has a roller chain fixed to the plate or stationary and a chain tensioning device, the roller chain being guided over two deflecting elements and in the area between the deflecting elements, a drive gear encompassing loop.
  • a roller chain fixed to the plate or stationary and a chain tensioning device Such an arrangement is known from DE-A-27 55 419.
  • Parking plates of this type can be moved in various positions by this roller chain drive, so that, for example, access routes to other parking spaces are only temporarily released. This means that the access routes to fixed parking spaces can be better used.
  • roller chain in its area engaging in the drive gear is additionally guided via at least one lifting element which is radially displaceable relative to the axis of rotation of the drive gear and is inserted in a tensioned roller chain in a , Axis-close position, in which the roller chain meshes with the teeth of the drive gear, while it is displaced radially outwards when the chain tensioning device is released and thereby lifts the roller chain out of the teeth of the drive gear.
  • these lifting elements do not appear because they are in a position close to the axis, in which the roller chain engages around the drive gear in the usual way and meshes with its teeth.
  • the chain tensioner is released.
  • the lifting elements are displaced radially outwards and lift the roller chain out of the teeth of the drive gear, so that the roller chain no longer meshes with the teeth of the drive gear. In this position, the parking plate can be easily moved from the edge, since the roller chain is no longer in engagement with the drive gear.
  • the radially outward movement of the lifting elements can be brought about by a suitable mechanical transmission, for example by a lever linkage to be operated separately. It is also advantageous if this actuating device is coupled to the chain tensioning device, so that when the chain tensioning device is released, the mechanism which moves the lifting elements radially outward is also inevitably actuated.
  • the lifting element is acted upon radially outward by an elastic energy store, the force of which is dimensioned sufficiently large to lift the untensioned roller chain out of the teeth of the drive gearwheel, but which is only so large that the lifting element is removed by the means the chain tensioner roller chain is moved to the axis-near position.
  • an elastic energy store the force of which is dimensioned sufficiently large to lift the untensioned roller chain out of the teeth of the drive gearwheel, but which is only so large that the lifting element is removed by the means the chain tensioner roller chain is moved to the axis-near position.
  • the lifting elements are connected to the drive gearwheel in a rotationally fixed manner. As a result, there is no relative movement between the roller chain and lifting elements in normal operation, so that the wear is kept small.
  • the roller chain only moves relative to the lifting elements in the event of a malfunction.
  • the lifting elements form a sliding guide for the roller chain excavated from the teeth of the drive gearwheel in the extended state.
  • the lifting elements it would also be possible for the lifting elements to rest on the roller chain with rollers, so that the roller chain rolls on these rollers in the event of a malfunction.
  • the lifting elements form a closed ring in the retracted state.
  • the lifting elements are displaceably mounted on radial guides and if there are compression springs between adjacent lifting elements, which push the neighboring lifting elements apart in the circumferential direction.
  • the forces exerted by the compression springs on the lifting elements also have a radial component which, when the roller chain is released, shifts the lifting elements radially outwards and thus lifts the chain out of the teeth of the drive gear.
  • a guide body is arranged on the shaft of the drive gear, in which the lifting elements are mounted so as to be radially displaceable.
  • the lifting elements are arranged directly next to the plane of the drive gear and rest on the plates of the roller chain.
  • the lifting elements preferably have adjacent guideways for the inner and outer plates of the roller chain, which are stepped in accordance with the outer diameter of the plates. In the event of a malfunction, this results in exact guidance of the roller chain along the outwardly displaced lifting elements.
  • a parking plate which can for example be displaceable on rollers along a horizontal rail guide.
  • a chain running parallel to the direction of displacement engages on one side of the parking plate and is guided over various deflection rollers past the drive shown in FIG. 1 to the opposite side of the parking plate. If the roller chain is moved along the rail guide, the parking plate is also moved.
  • roller chain 1 In order to move the roller chain 1, it is guided around two closely spaced deflection rollers 2 and 3 with parallel axes of rotation so that it forms a loop 4 between the two deflection rollers 2. This is placed around a drive gear 5 and meshes with the teeth 6 of this drive gear 5.
  • the drive gear 5 is non-rotatably connected to a drive shaft 7 ( Figure 2), which in turn is rotated by a motor, not shown in the drawing, for example an electric motor can be.
  • a chain tensioning device which is not shown in the drawing, is provided for the roller chain 1.
  • Simple constructions are known to the person skilled in the art for this purpose, for example the roller chain can be passed between two rollers which can be pivoted relative to one another and whose distance from one another is adjustable. It is only essential in the context of the invention that this chain tensioning device can be transferred from the tensioned position into a released position in which the roller chain is loosened.
  • a guide body 8 is pushed onto the drive shaft 7 from the free side and is connected to it in a rotationally fixed manner by means of a spring 9 (FIGS. 2 and 3).
  • the guide body 8 is supported on a shoulder 10 of the drive shaft 7 and is fixed in the axial direction by the drive gear 5, which is held on the free end of the drive shaft 7 by means of a screw 11 screwed into the end face of the drive shaft 7.
  • the drive gear 5 is also non-rotatably connected to the drive shaft with a spline connection.
  • the guide body 8 has on its end face facing the drive gear wheel an annular groove-shaped recess 12 into which three radially directed guide bolts 13, each offset by 120 °, are inserted. These engage with their free end in a blind hole 14 in a hub 15 surrounding the drive shaft 7 and are screwed into radial threaded bores which are located in the wall 17 which delimits the recess 12 on the outside.
  • Each of the guide bolts passes through a guide bore 18 of a lifting element 19 which is in the form of a circular arc and extends over 120 °, which are located in the annular recess 12 and are radially displaceable along the guide bolt.
  • the lifting elements 19 are adapted in their inner circumference to the outer circumference of the hub 15, i.e. they lie with their inside against the outside of the hub when their mutually facing end faces touch (FIG. 3). The three lifting elements then form a ring that closely surrounds the hub.
  • Blind hole bores 20, which are aligned with one another, are machined in the circumferential direction in the mutually facing end faces of the lifting elements 19.
  • Two mutually aligned blind holes in adjacent lifting elements together hold a compression spring 21 which is supported on the bottom of the two blind holes. This compression spring is dimensioned such that it is compressed when the lifting elements 19 are in their position close to the axis in the manner shown in FIG.
  • the lifting elements On their side facing the drive gear 5, the lifting elements extend right up to it and there have two sliding surfaces 22 and 23 running in the circumferential direction and axially parallel.
  • the sliding surface 22 closest to the gear lies against the underside of an inner plate 24 of the roller chain 1
  • the sliding surface 23 which is offset somewhat outward in the radial direction and is somewhat further away from the drive gear lies against the inside of an outer plate 25 of the roller chain 1, as can be seen from the representation of the Figure 2 shows.
  • the radial dimensions of the slide guides 22 and 23 are chosen so that the roller chain engages in the teeth 6 of the drive gear 5 when the lifting elements are in their near-axis position (FIGS. 2 and 3).
  • the roller chain is expanded around the drive gear 5 and in the radial direction so far from the drive gear that the teeth 6 of the drive gear 5 no longer mesh with the roller chain 1 ( Figures 4 and 5).
  • roller chain 1 In normal operation, the roller chain 1 is tensioned by the chain tensioning device.
  • the loop 4 of the tensioned chain exerts a radially inward force on the lifting elements, which pushes them into their innermost position against the action of the compression springs 21.
  • the roller chain In operation, the roller chain can thus mesh with the drive gear 5, as shown in FIG. 6.
  • the lifting elements 19 can be displaced radially outwards under the action of the compression springs 21, since the released chain no longer displaces the lifting elements radially inwards.
  • the roller chain on the slide guides 22 and 23 is taken radially outwards, so that the roller chain finally surrounds the drive gear 5 at such a distance that there is no longer any engagement with the teeth 6 of the drive gear (FIG. 7).
  • the parking plate can be moved by hand without this displacement movement being hindered by the blocked drive gear.
  • the properties of the compression springs 21 must be adapted accordingly for this purpose. They must only be so strong that the roller chain tensioned by the chain tensioning device can move the lifting elements into the position lying in the radial direction on the inside; if the loose chain slides over the sliding guides 22 and 23 when the parking plate is moved manually.
  • the chain is attached to the platforms and the drive is mounted in a fixed position.
  • the drive is mounted in a fixed position.
