The present invention relates to a parking device that utilizes the power of a motor vehicle by being connected to a drive shaft of a moving wheel which is mounted on a vehicle chassis via a gear mechanism such as a bevel gear, and which is connected to a drive shaft of a vehicle. It is arranged diagonally on one side of the chassis and divided,
The divided circumferential drive rotation shafts are linked via a forward gear mechanism, and the chassis can be freely turned and moved via a moving wheel mounted on each drive rotation shaft and a driven wheel disposed at the other diagonal position. This invention relates to a parking device.

<Prior art> Conventionally, cars have been parked in designated parking areas except in special cases, but all parking areas do not necessarily have sufficient space. However, as shown in Figure 1, when car 1 enters parking lot 3 from road 2, it is impossible due to the car's maneuverability without taking up extra space, and as a result, other cars There is also the disadvantage that it is difficult to turn into the parking lot when the parking space is limited to the road 2 as shown in Fig. 2.

On the other hand, special lateral movement devices and rotation devices have also been developed, but these have the disadvantage of being complicated and costly.

Further, as shown in FIGS. 3 and 4, the chassis 4 made of a suitable light material is made slightly larger than the planar size of the automobile 1,
A pair of driving rotation shafts 5 and a driven rotation shaft 5' are respectively mounted on bearings 6, 6' on both sides, and a pair of moving wheels 7 are mounted on each side.
, 7' are fixedly installed, and a bevel gear 8 is fixed to a predetermined portion of the drive rotation shaft 5.

A drive shaft 10 is loosely inserted into the bearings 9, 9 provided on the chassis 4, intersecting with the drive rotation shaft 5.
A bevel gear 11 that engages with the bevel gear 8 and a passive roller 13 that is integrated with the bevel gear 11 and faces a slit 12 formed in the chassis 4 are loosely inserted into the vehicle body 4.

Note that the passive roller 13 is provided at a position where it is engaged with only one of the rear driving wheels 14 of the automobile 1.

Further, reference numerals 15 and 15 are entry steps for the chassis 4, a stopper 16.16 is provided on one inside of the step 15 and the front frame of the chassis 4, and 17.17 is a manually operated grip.

In the above-mentioned parking device, when a car 1 enters a narrow road 2, the undercarriage 4 is manually pulled out from the garage 3' via the manual operation grips 17, 17, and the undercarriage 4 is set on the road. Car 1 enters step is, i at low speed
s, when one of the rear drive wheels 14 comes to a position where it locks on the passive roller 13, a differential gear (not shown) of the automobile 1 automatically locks the drive wheel on the passive roller 13 side. Only bevel gear 14 rotates, and bevel gear 11
．． The drive rotation shaft 5 is rotated via the shaft 8.

When the drive wheels 14 transmit power to the passive rollers 13, the car 1 will substantially automatically stop, and if there is a risk of it moving forward due to inertia, a small stopper 18 is attached for the front wheels that can be climbed over. Just do it.

When the drive rotation shaft 5 rotates as described above, the moving wheels 7,
1', the chassis 4 is moved laterally in the direction of the arrow with the automobile 1 placed thereon, and is stored in the garage 3' in parallel.

Then, the chassis 4 enters the garage 3' and the stopper 16.1
6 comes into contact with an appropriate stopper receiver (not shown), the chassis 4
stops moving, therefore, the moving wheels 7, 1' stop rotating, and as a result, the passive roller 13 also stops, and the differential gearing of the driving wheels 14, 14 of the automobile 1 is selected. Therefore, the circumferential drive wheels 14 and 14 also rotate and the car 1 moves forward, and as soon as it knows that it will leave the chassis 4 and park at a predetermined position in front of it or start, the engine is stopped and the car moves on the chassis 4. Stop and park 1.

Further, when leaving the vehicle 1, the vehicle 1 is easily and automatically returned to the road while being moved in parallel by performing the operation in reverse to the above-described operation.

<Problems with the prior art> However, in the conventional parking device described above, since the vehicle platform 4 is of a type that moves in parallel, it takes time to rotate the passive roller 13 via the vehicle 1. In addition, it requires a sufficient space for moving and placing the vehicle platform 4, and as a result, there is a disadvantage in that there is a loss of space.

<Purpose of the Invention> The purpose of the present invention is to solve the problems of the parking device based on the prior art described above, and to solve the problem by using the power of the automobile and its differential gear mechanism. It is an object of the present invention to provide an excellent parking device which can be easily turned and moved based on the above-mentioned structure to secure a sufficient parking space, and which is beneficial to the field of use of ancillary equipment in the housing industry.

<Structure of the Invention> In order to solve the above-mentioned problems, the structure of the present invention, which is based on the above-mentioned claims and in accordance with the above-mentioned object, is aimed at solving the above-mentioned problems by driving a car onto a parking chassis and one of the driving wheels of the vehicle When engaged with the rollers, the movement of the vehicle is slightly stopped by the action of the differential gear mechanism, and the passive rollers are rotated by the power of the vehicle, thereby rotating the moving wheels in a predetermined manner via the forward gear mechanism. Then, when the movable chassis is rotated and moved to a predetermined position, and the stopper stops the chassis, the passive roller also stops rotating, so that the engine of the vehicle is stopped and the vehicle is parked at that position or parked at the predetermined position. move forward,
Conversely, when leaving the warehouse, technical measures have been taken to allow the vehicle to easily retreat by performing the reverse operation described above.

<Embodiment - Configuration> Next, one embodiment of the present invention will be described below based on FIG. 5.

Similar to the conventional parking apparatus described above, a passive roller 13 is provided on the vehicle chassis 4', and a bevel gear 11 is coaxially and integrally fixed to the passive roller 13.

Further, one drive rotation shaft 51 and the other drive rotation shaft 51' are pivotally supported on the chassis 4' in a state in which they are connected to each other via a forward gear mechanism 19 at diagonal positions of the chassis 4'. A bevel gear 8' as a gear mechanism integrally mounted on the drive rotation shaft 51 meshes with the bevel gear 11 as the gear mechanism.

Moving wheels 71 and 71 are integrally attached to both ends of the drive rotation shafts 51 and 51', respectively.

Further, at other diagonal positions of the vehicle chassis 4' corresponding to the moving wheels 7L71, driven wheels 71', 71' whose shafts are pivotally supported by the vehicle chassis 4' on the diagonal are provided.

<Embodiment - Effect> In the above-described configuration, if turning is required when the automobile 1 enters the garage 3' under the narrow conditions shown in FIG. 2, the chassis 4' is installed on the road and the incoming automobile 1 is Similarly, when the vehicle 1 is driven onto the chassis 4' from the entry step 15.15 and the rear driving wheels 14 engage with the passive rollers 13, the vehicle 1 automatically stops, and at the same time the passive rollers 13 are given rotational force and the chassis 4' is It turns as shown by the arrow by the moving wheels 7L71 via the bevel gears i, a', the forward gear mechanism 19, and the drive rotating shafts si, si'.

When the stopper 16' abuts and engages the appropriately attached passive body, the vehicle platform 4' stops turning and the passive roller 13 stops, so that if the automobile 1 is subsequently stopped or moved forward, good.

During this time, the space occupied by the vehicle platform 4' after the movement is smaller than that of the type in which the vehicle platform 4' is moved in parallel.

Further, depending on the design, a stopper may be attached to the front wheel, the stopper may be used to stop the vehicle, and one of the drive wheels may be used to perform the above-mentioned movement.

<Effects of the Invention> As described above, according to the present invention, the drive rotation shafts to which the passive rollers that engage with the drive wheels of an automobile are linked via the gear mechanism are connected to one drive rotation shaft and the other drive rotation shaft, respectively. By arranging and dividing the vehicle chassis in one diagonal direction, the axial length of the divided two-part drive rotation shaft is shortened, which extends the life of the shaft against rotational bending loads and increases the strength. A more reliable effect can be achieved in terms of gender.

In addition, by linking the rotation shafts of both parts through a forward gear mechanism, the vehicle chassis can be rotated by rotating the driving wheels of the automobile, and the vehicle chassis can be moved in parallel. Compared to this, less space is required after the vehicle is moved, resulting in an excellent effect of increasing the number of parking spaces per unit area.

In addition, compared to the type that moves the chassis in parallel, the number of rotations of the passive rollers can be reduced to achieve rotation, so the driving time of the vehicle can be shortened, and the amount of exhaust gas emitted from the vehicle is accordingly reduced. This results in excellent economical and environmental health benefits.
