Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a parking device for a motor vehicle. More particularly, the invention comprises at least two pedestals spaced apart from one another at one end and movably supported on a machine frame or structural member;
The other end of the cradle is movable by a drive device to be selectively positioned adjacent to the doorway, and the lower cradle is held in the upper cradle by a traction member.

[Conventional technology]

A parking device of the above-mentioned type is known, for example, from German Patent Application No. 28 34 498.

In such conventional devices, driving devices such as hydraulic cylinders must be provided outside the pedestal on both sides to move the pedestal.

[Problem that the invention seeks to solve]

For this purpose, space is required for installing the drive between the pedestal and the structural wall or between adjacent pedestals. In addition, special means, such as torsion bars, toothed racks or articulated shafts, must be provided to ensure that the two supports are synchronized when loads are applied unevenly to the supports. be.

In view of the above points, it is an object of the present invention to provide a parking device of the type described above, which allows optimal use of the space available for the cradle of the parking device. do.

[Means for solving problems]

In the present invention, it comprises at least two cradle having one end spaced apart from each other and movably supported on the machine frame or a structural member,
The other end of the cradle is movable by a drive device so as to be selectively positioned adjacent to the doorway, and the lower cradle is held on the upper cradle by a traction member. an arm is provided above each lateral end of the cradle in a vertical plane parallel to the end, one end of the arm extending perpendicularly to the lateral end above the bearing end of the cradle; The cradle is supported on a machine frame or a structural member so as to be rotatable around a horizontal axis of rotation, and the arms disposed at both ends of the pedestal are rigidly connected to each other. , the upper cradle is held by a traction element at the free end of each arm, the drive being adapted to engage the arm and rotate it into various angular positions about said axis of rotation. The apparatus achieves the above objectives.

[Effect]

In this structure, all the drives are located above the upper pedestal and no space is required for the drives on the sides of the cradle.

Only a traction member, such as a cable or chain, connects the two superimposed cradle to each other or connects the upper cradle to the arm.
Moreover, these traction elements only require very limited space, so that as a practical matter no parking space is lost due to the installation of these traction elements. By tightly connecting the two arms to each other, the movement of the cradle is perfectly synchronized, even under uneven loads.
Therefore, no additional measures are required to stabilize the pedestal. This means that the available construction space can be used much more efficiently compared to arrangements that require additional equipment for synchronization.

Since the space above the upper cradle is required in each case for the storage of a motor vehicle parked on the upper cradle when the cradle is raised, the arm and its drive are additionally required. I try not to take up too much space.

It is particularly preferred that the two arms are connected to each other by a transverse member which is torsionally rigid and extends along the axis of rotation. This structure forms a U-shaped grazing element which is rotatably supported behind a pedestal, which is thereby suspended from the free end of the arm.
Therefore, the pedestal can be brought closer to the doorway as desired simply by rotating this U-shaped locking element.

It is preferable that the horizontal member is disposed above the upper cradle at a distance equal to or greater than the height of the engine cover of an automobile parked on the cradle. In this way, the entire space above the upper cradle is available for parking a motor vehicle. The laterally extending cross member is located above the engine cover of a parked motor vehicle and does not impinge on it.

Furthermore, it is preferable that the length of the arm is less than half the length of the pedestal. Thereby, no additional vertical space is required even when the arm swings at a relatively large swing angle.

The traction member may extend from the support member on the arm to the support member on the pedestal at an angle towards the free end of the pedestal. The attachment position of the traction member closest to the entrance/exit may be moved to the vicinity of the entrance/exit, and with this configuration, the pedestal is stably held at the attachment position of the support member and the traction member.

In the first embodiment, the pedestal is swingably supported around a fixed shaft extending parallel to the rotation axis. Therefore, the rotational movement of the arm is converted into a pure rotational movement of the pedestal. Due to the slope of the traction member, the angle of rotation of the arm is different from the angle of rotation of the pedestal. The rotation angle of the pedestal corresponding to the rotation angle of the arm is determined by the difference in distance from the rotation axis to the attachment position of the traction member. That is, by moving the cradle closer to the entrance/exit, it is possible to adapt to each structural condition.

In yet another preferred embodiment, the pedestal is supported on a movable stage so as to be rotatable about an axis extending parallel to the axis of rotation, and the movable base is movable in a vertical guideway. be. A second traction element is supported on the arm and engages the upper cradle between the support end of the upper cradle and the support member of the first traction element. The upper cradle is thus suspended from the arm by two traction elements which engage the cradle at a distance from each other. The moving platform only guides the cradle during its up and down movement.

In this embodiment, it is particularly preferred that the attachment positions of the first and second traction elements to the arm are spaced apart so that they are at different distances from the axis of rotation. With this configuration, when the arm is rotated, the attachment point of the traction member on the arm traces a different trajectory.
The cradle suspended from these arms is moved up and down and rotated. This allows the cradle located above to be lifted on the side facing the doorway, while the cradle located below can extend horizontally. Even if the entire length of the lower cradle does not reach the level of the entrance/exit, if you lift and tilt both cradle, the car is already mounted on the lower cradle, so the cradle can be moved. The path can be reduced as a whole.

It is preferable that the second traction element is a rigid rod, whose both ends are pivotally supported by an arm and an upper pedestal 9, and is capable of absorbing not only a pulling force but also a pressing force. With this configuration, the cradle is reliably and stably supported even when a load is applied only to the end facing the entrance/exit, such as when the cradle is being mounted on a cradle of an automobile, for example.

The drive arrangement of the cradle in the embodiment shown is particularly space-saving, and in particular makes it possible to advantageously install the cradle for one or more parking device spaces adjacent to one another. in this case having two or three adjacent parking device spaces;
It is also sufficient to provide a cradle with only two arms located above the lateral ends of the cradle. The transverse member connecting the arms then extends over the entire width of the pedestal. A simple construction of the drive device can be achieved by means of a unit in which the arm and the transverse member are constructed similarly and stably. However, at the same time, this drive device can handle loads acting unevenly on the pedestal, such as when only one car is mounted on the pedestal, without adding other additional structural elements. can be fully compensated. Of course, in this case it is necessary to design the structure to be stable as well, ie the arms and cross members must be resistant to bending and torsion. In arrangements with a number of adjacent parking spaces, it is also possible to provide arms arranged above the boundaries between adjacent spaces, so that the arms are connected to each other by transverse members to form a rigid unit. It is possible.

There is no need to install the drive device in the space directly above the arm, and therefore there is space for installing the control device and drive device such as a hydraulic unit at the top rear of the structure or space for installation in the building. Another advantage is that it can be taken.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The parking device shown in FIG. 1 is arranged in a special structure with a floor 1, a vertical rear wall 2, a front wall 3 and a horizontal entrance 4 located above the floor 1 and connected to the front wall 3. has been done. Ceiling 5 (Fig. 2, 3
) is connected to the upper end of the rear wall 2, and as a whole forms a space for accommodating a parking device that can enter only from the entrance/exit 4. This space is laterally limited by side walls, not shown, and the distance between them is large enough to accommodate a number of similar parking devices adjacent to each other. There is.

The parking device itself consists of two vertical machine frame parts 6, which stand up on the floor 1 and are held to the rear wall 2 by suitable attachment members 7. In the embodiment shown in FIGS. 1 to 3, the movable table 8 is guided by each machine frame member 6 so as to be movable up and down. Two vertically overlapping supports 9 and 10 are supported with a space between them between the movable bases 8 of adjacent machine frame members 6, and a horizontal shaft connecting the two machine frame members 6. It can be rotated around. The movable table 8 is mainly used to maintain a constant vertical distance between the ends adjacent to the rear wall of the cradle 9, 10, and to guide the cradle 9, 10 on the machine frame member 6. It is used for.

The cradle 9, 10 itself has at its lateral edge a reinforcing section 11, which at the same time forms the lateral boundary of the pedestal 9, 10.

A structural unit 12 is supported on the upper part of the machine frame member 6 so as to be rotatable around a horizontal axis of rotation connecting the two machine frame members 6. This structural unit 12
consists of two arms 13 and a transverse member 14 extending along said axis of rotation and rigidly connecting the arms 13 to one another. The arms 13 extend in a vertical plane extending above the lateral edges of the cradle 9, 10, their length being less than half the length of the cradle 9, 10. The structural unit 12 consists of an arm 13 and a cross member 14, which structural unit 12 is designed to be bend-resistant and torsionally rigid. This structural unit 12 is thus designed to be very robust and is therefore a rigid component.

A hydraulic piston cylinder unit 16 is rotatably supported on a protrusion 17 of an adjacent machine frame member 6, and a piston rod 15 of the hydraulic piston cylinder unit 16 is pivotally mounted on the lower surface of each arm 13. When the piston rod 15 is extended or retracted, the arm 13 pivots about its axis of rotation and, since the structural unit 12 is rigid against bending and torsion, both arms are thereby similarly Rotated.

The lifting cable 19 is attached at one end to the free end of the arm 13 and held at the other end to the side of the reinforcing section 11 of the upper cradle 9. The mounting position is chosen such that it slopes downward from the free end of the arm of the lifting cable 19 towards the upper cradle 9. Furthermore, another lifting cable 20 is attached to the upper cradle 9 of the first lifting cable 19 described above.
The other end is supported at the mounting position on the lower cradle 1.
0 reinforcement section 11 such that the lower cradle 10 is substantially parallel to the upper cradle 9.

A lift bar 21 is rotatably connected between the free end 18 of the arm 13 and the rotation axis. The other end of the lifting bar 21 is located between the attachment point of the lifting cable 19 and the support member of the moving platform 8,
It is pivoted to a reinforcing section 11 of the upper cradle 9. In this way, the upper cradle 9 is stably suspended from the arm 13 by the lifting cable 19 and the lifting bar 21. Lower cradle 10
is suspended from the upper cradle 9 by a cable 20 and a carriage 8, so that the cable 20 and carriage 8 act as a parallelogram guide bar.

Arm 13 is piston cylinder unit 16
When the arm 13 is rotated, the upper and lower cradle suspended from the arm 13 are raised (FIG. 2) or lowered (FIG. 3) as desired. In the raised position of the cradle 9, 10, the lower cradle 10 is aligned with the doorway as shown in FIG.
A car to be parked can be taken in and out from the entrance 4 to the lower cradle 10. In addition, in the lowered position, the upper cradle 9 is aligned with the doorway as shown in FIG.
A car to be parked can be taken in and out from the entrance 4 to the upper cradle 9. Therefore, the automobile can be taken in and out of the upper cradle 9 while the automobile is mounted on the lower cradle 10.

Due to the fact that the lifting cable 19 and the lifting bar 21 are attached to the arm 13 at different distances from the axis of rotation of the arm means, the cradle is not only moved up and down, but also rotated, so that in the raised position In this case, the doorway is raised at its free end, while in the lowered position the cradle extends substantially horizontally (see FIGS. 2 and 3). If such an additional rotational movement is not desired, it is also possible to provide the lifting cable 19 and the lifting bar 21 at the same point on the arm 13.

The embodiments shown in FIGS. 1 to 3 make it possible to use pedestals with one or more parking spaces relative to each other. In this case,
The entire structure remains unchanged, except for the width of the cradle and the width of the cross member connecting the two arms.

The parking device shown in FIGS. 4 and 5 is constructed similarly to the parking device shown in FIGS. 1 to 3. Therefore, the same parts are shown with the same numbers.

This embodiment differs from the embodiments shown in FIGS. 1 to 3 in that the pedestals 9 and 10 are rotatably supported on fixed horizontal fixed shafts 22 and 23. There is. Additionally, the lifting bar 21 is omitted.

The cradle 9, 10 of this embodiment is tilted downward in its lowered position and upwardly in its raised position. The floor surface 1 is also sloped to correspond to the slope of the lower pedestal 10 in the lowered position, but the end 24 in the immediate vicinity of the doorway is horizontal. For this purpose, a part of the lower pedestal 10 located very close to the entrance is rotatable upward relative to the other part of the pedestal 10, and this part is in the lowered position. It rests on a horizontal floor section 24 when located at .

In the illustrated embodiment, the machine frame part 6 is supported on the floor and is held on the rear wall 2 of the structure by means of mounting members 7. It is also possible to connect the machine frame part 6 to a horizontal, forwardly extending leg, so that the machine frame part, together with the leg and the cradle supported on the machine frame part, It is also possible to use it as a separate structural unit that is not supported and connected to the building. This independent structural unit can be installed inside a pre-constructed building without requiring any special installation work.
