Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet car stop device in a mechanical parking lot. More specifically, a pallet is used for transporting and storing a car in a pallet type mechanical parking lot, but when the car is loaded and moved by an elevator or a trolley, the car is prevented from jumping out of the pallet. For this reason, a car stop device is attached to the pallet. The present invention relates to such a car stop device.

[0002]

2. Description of the Related Art As shown in FIG. 10, a conventional car stopping device is a fixed type in which car stopping members 51 and 52 are fixed on a pallet. Therefore, in order to enable parking regardless of the size of the tire diameter and to ensure the ease of getting in the vehicle, it is necessary to provide a gap between the car stop members 51, 52 and the tire W. For this reason, when the side brakes are not effective or when the user forgets to pull the side brakes, the car may get over the car stop members 51, 52 and jump out of the pallet. Further, when the front wheel of the automobile is used as a reference, the front end position and the rear end position of the automobile vary depending on the vehicle type, but it suffices if the variation can be absorbed by the gap.
In general, it cannot be absorbed, so the length of the pallet is increased so that the car does not extend beyond the pallet. Therefore, the pallet generally has an extra length, which reduces the volumetric efficiency of the parking lot.

Therefore, as a movable car stop member, Japanese Patent Laid-Open No. 6-240913 (conventional example I) and Japanese Utility Model Laid-Open No. 5-60 are used.
No. 42 (conventional example II) was proposed. In Conventional Example I, when an automobile is placed on a pallet, a pair of rod-shaped detent members pivot horizontally to sandwich the tire of the automobile from both sides. Therefore, the tires of the vehicle are held between the pair of vehicle stop members even if they are located slightly back and forth. In the conventional example II, the car stop member is configured such that two plate members are pin-connected to each other so as to stand up in a triangular shape or be folded flat.

[0004]

The wheel stop member of the pallet is more effective in stopping the wheels when it comes into contact with the tread surface of the tire in parallel. In the conventional example I, the wheel stop member is parallel to the tread surface of the tire. Only one of the pair of car stop members hits, and both of the car stop members may incline and contact the tire depending on the stop position of the tire. Moreover, since the wheel base differs depending on the car model,
The above-mentioned positional relationship is rare. Further, the tire is usually elastic, and if the car stop member comes into contact with the tire, it may bite into the tire. When the car stop member is retracted with the car stop member digging into the tire, a large bending force is applied to the car stop member, and sometimes the member may be deformed and the tire may be damaged. Also,
There are various drawbacks such as the need for a large output drive device for the vehicle stop member.

In Conventional Example II, since the pallet side pivotal support portion of the car stop member is fixed, if the stop position of the vehicle deviates from the center of the car stop, the wheel cannot be reliably sandwiched from the front-rear direction, and the gap is left. Will occur. Therefore, the automobile moves back and forth within the gap, which is inferior in safety. Moreover,
Since the distance between one wheel stopper member and the other wheel stopper member is constant, it is necessary to consider the diameter of the wheel.

In view of the above-mentioned circumstances, the present invention allows a car stop member to be brought into contact with a tread surface of a tire in parallel with the tire tread regardless of the size of the tire diameter or the length of the wheel base of the automobile, without forming a gap with the tire. Prevents the vehicle from jumping out, and the car stop member does not bite into the tire. When the car stop member is retracted, it can be released smoothly without deforming the car stop member or damaging the tire. Therefore, it is an object of the present invention to provide a car stop device capable of shortening the length of a pallet.

[0007]

According to a first aspect of the present invention, there is provided a car stop device for a pallet for transporting an automobile in a mechanical parking lot, wherein a pair of car stop members are slidably arranged in front of and behind the center of the car stop on the pallet. In addition, the sliding motion of each car stop member can be operated independently of the sliding motion of the other car stop member, and the pair of car stop members are moved forward to clamp the wheels of the vehicle from the front and rear, and the wheels are moved backward to retreat to each other. The feature is that the pinching of the wheel of is released. The car stop device according to claim 2 is characterized in that elastic means for urging the pair of car stop members in a direction of advancing each other is provided between the pallet and the car stop member, and a retraction drive device for retracting the pair of car stop members to each other is provided. It is characterized in that it is provided on the passenger compartment side. According to a third aspect of the present invention, the elastic means is a gas damper, one end of the gas damper is connected to the vehicle stop member, and the other end is connected to the pallet. A car stop device according to claim 4, wherein the car stop member is a slide plate biased by the resilient means, and a car stop main body fitted to the slide plate with some play in the sliding direction.
A car stop stopper rotatably attached to the tip of the car stop body for holding the car stop stopper in a laid-down posture with a small undulation angle with respect to the pallet upper surface.
A holding table attached to the tip of the car stop body, and a push-up tool formed at the tip of the slide plate to hold the car stop stopper in a standing posture with a large undulation angle with respect to the upper surface of the pallet. To do. The vehicle stopping device according to claim 5, wherein the reversing drive device includes an endless chain wound between a drive sprocket driven by a motor and a driven sprocket, and a pusher attached at a proper position of the chain. The tool is moved to push the engaging portion provided on the slide plate of the car stop member to retract the pair of car stop members against the elastic means.

[0008]

According to the invention of claim 1, the pair of front and rear car stop members independently slide in the front-rear direction to sandwich the wheel of the vehicle without interlocking with each other. Therefore, regardless of the stop position of the vehicle,
The wheels of the vehicle can be sandwiched from the front and rear regardless of the length of the wheel base of the vehicle and the size of the wheels of the vehicle. In this case, since the car stop member is in close contact with and parallel to the wheel, even if the side brake is forgotten, the vehicle is reliably prevented from jumping out. In the invention of claim 2, the elastic means for sliding the car stop member is a component that does not require a power source or a control device, and the reverse drive device for retracting the car stop member is provided on the side of the passenger compartment. The configuration is simple. Further, since it is not necessary to provide the backward drive device for all the pallets, the facility cost of the entire parking lot can be reduced. According to the invention of claim 3,
Since the elastic means is composed of a gas damper, a large output can be obtained with a compact structure. For this reason, the thickness of the pallet can be reduced, and the vertical height of the parking lot need not be increased. According to the invention of claim 4, when the slide plate is biased in the direction in which the wheel is clamped by the elastic means, the car stop body fitted to the slide plate also moves in the clamp direction with a delay of the play distance, and the slide plate is stopped. The vehicle stops a little forward from the body toward the wheels, and the car stop stopper hits the wheels. At this time, the push-up tool at the tip of the slide plate pushes up and holds the car stop stopper in a standing posture with a large undulation angle, so that the tire is sandwiched between the standing car stop stoppers, and the effect of preventing the vehicle from jumping out is further enhanced. Further, since the car stop stopper is prevented from being caught in the tire, the reverse operation can be performed smoothly and the power of the reverse drive device can be small. Then, when the slide plate is retracted by the reversing drive device, the car stop body fitted to the slide plate also moves backward with a distance of play, but at this time, since the push-up tool is separated from the car stop stopper, The car stop stopper falls down on the holding table of the car stop body, and the stilt angle is kept small. As a result, the riding height when the vehicle enters and leaves the pallet is lowered, and the vehicle can be smoothly loaded and unloaded. According to the fifth aspect of the present invention, a simple reverse drive device having a motor, a sprocket, and an endless chain as main components can be obtained.

In the forward state (shown by the solid line), the rod-side mounting portion 39 of the gas damper 40 has a hole 38 (see FIG. 2) formed in the rear portion 13a of the top plate 13.
However, since it is hidden by the lower surface of the top plate 13 in the retracted state (shown in phantom line), the mounting portion 39 and the tires are not damaged even when the wheels of the automobile pass through. When the slide plate 30 is advanced by the gas damper 40, the push-up surface 36 keeps the car stop stopper 20 in a standing posture with a large standing angle θ1 with respect to the upper surface of the pallet P, and the car drive vehicle body 10 is driven by the reverse drive device. When the vehicle is retracted, the holding surface 22 of the holding table 21 holds the car stop stopper 20 in the laid posture in which the undulation angle θ2 with respect to the upper surface of the pallet P is small. Further, if the pusher 48 is retracted to the side of the sprocket 45, it will not hinder the movement of the pallet P.

Next, the advantages of the car stop device 4 will be described. FIG. 8A shows a state in which the car stop members 5 and 6 are retracted in the direction of arrow R by the retract drive devices 7 and 8. In this case, since the car stop stopper 20 is in the laid-down posture, the tires of the automobile can easily get over and the automobile can smoothly enter and leave the pallet P.

In FIG. 8B, when the pusher 48 is moved toward the center 6 of the car stop, the car stop stopper 20 or the like is moved to the gas damper 40.
Indicates a state in which the vehicle is moving forward in the direction of the arrow and holding the wheel W of the automobile. In this case, the car stop stopper 20 comes into contact with the tread surface of the tire in parallel, and since the standing angle thereof is large, it is possible to reliably prevent the vehicle from running out. Further, since the car stop stopper 20 stands up and comes into contact with it, it does not bite into the tire so that the tire is not damaged. Also, when the vehicle is retracted, the vehicle stopper 20 is laid down and then retracted, so that the vehicle stoppers 20 can be retracted with a small force, and no unreasonable force is applied to the vehicle stopper members 5 and 6 so that inconvenience such as deformation does not occur. Furthermore, car stop stopper
The forward movement of 20 is performed by the gas dampers 40 that each has, and since they operate independently of each other without being interlocked with each other, even if the wheels stop at a position deviating from the wheel stop center b, the wheels can be reliably pinched and the tires The wheels can be reliably clamped regardless of the size of the diameter and the length of the automobile wheel base. Further, in this car stop device 4, the length of the pallet P can be shortened. That is, when the automobile stops on the pallet, the wheels are less likely to deviate from the car stop center b, and the car stop stopper 20 tightly sandwiches the wheels from the front and the rear, so that an extra gap is provided like a fixed car stop device. Since it is not necessary, the total length of the pallet can be shortened by the amount corresponding to the gap. Therefore, the entire length of the parking lot can be shortened, space can be saved, and a large number of cars can be accommodated in the same size parking lot.

Next, another embodiment of the present invention will be described.
In the above-described embodiment, the car stop devices 4 are provided on the left and right sides of the car stop center b in front of the pallet P, but the car stop devices may be provided on the left and right behind the pallet P.
Further, the car stop device of the present invention can be applied to any pallet type parking lot and any pallet. Further, as the elastic means of the car stop device, a tension spring may be used instead of the gas damper 40. For example, a tension spring may be interposed between the slide plate 30 and the car stop center side of the pallet P to slide. The plate 30 may be biased in the forward direction, and the slide plates 30 of the front and rear car stop members 5, 6 may be connected to each other by long tension springs so as to attract each other. Also, the pusher 48 of the reverse drive device 7
May be moved by a cylinder device, a screw jack, or the like. In this case, it is necessary to project the engaging projection 37 a little further downward so that the upper end of the pressing tool 48 has a slight gap with respect to the lower surface of the pallet P.

[0021]

According to the present invention, regardless of the size of the tire diameter and the length of the wheel base of the automobile, the car stop member is brought into contact with the tread surface of the tire in parallel with the gap between the tire and the tire, and Prevents the vehicle from jumping out, prevents the car stop member from biting into the tire, and when the car stop member is retracted, it can be released smoothly without deforming the car stop member or damaging the tire. It is possible to provide a car stopping device that is sufficient for output.
