Description

[Detailed description of the invention] This invention relates to a car stop device used for a vehicle-mounted platform such as a parking pallet, and in particular, a wheel stopper that is pivotally connected to the vehicle-mounted platform and an operating arm that is pivoted at its midpoint to the vehicle-mounted platform. The operation arm can be raised and lowered by rotation, and the rotation of the operation arm is controlled by a tension spring installed between the top of the wheel stopper and the tip of the operation arm, and by resisting the bias of the tension spring when the vehicle platform is lowered. The wheel stopper automatically lies down only when the vehicle platform is lowered to a predetermined position on the floor by means of a protrusion on the floor that rotates the arm, and the wheel stopper automatically lies down to allow the vehicle to get on or off the vehicle platform. At all other times, the wheel stoppers are always upright and restrict the movement of the vehicle.

The applicant has proposed a type of parking equipment in which a large number of pre-prepared parking pallets are individually transported between the garage entrance and the parking space using an overhead crane to allow vehicles to enter and exit the garage. It has been proposed (Japanese Unexamined Patent Publication No. 158871/1983).

FIG. 1 shows a schematic plan view of this parking facility, and FIG. 2 shows a schematic front view thereof.
These are examples of parking facilities, but the garage 1 in FIG. 1 is surrounded by a side wall 2,
It has an entrance/exit 3, and parking pallets 5 are arranged on a floor 4. In this garage 1, as shown in FIG. 2, a guide rail 7 and a moving rail 8 are arranged on the ceiling 6, and a lifting machine 9 is attached to this moving rail 8, and an overhead crane is operated by these. Configure.

The vehicle then enters through the entrance 3 and gets onto the parking pallet 5 where it is waiting. this,
The pallet 5 on which the vehicle has been loaded is lifted by a hoisting machine 9 and transported to a predetermined parking position where it is placed. This is the parking state. Further, when leaving the warehouse, the pallet 5 is transported by a hoisting machine 9 to a position inside the entrance/exit 3, and at that position, the pallet 5 is placed on the floor 4.
The vehicle gets off the pallet 5 placed on top and exits the garage 1 through the entrance 3.

Now, in the case of the on-vehicle platform of the parking equipment as exemplified above, as a means of stabilizing the mounted vehicle when the on-vehicle platform is moved, there is a device that operates the parking brake of the vehicle or a vehicle stop device that is manually operated. It is possible to consider methods such as a method that protrudes and fixes the wheel stopper, but the problem with the means for operating the parking brake is that if the operation is not sufficient, the stability of the vehicle will be lost.
Means for manually operating the wheel stop device have the disadvantage that they are time-consuming to operate, and furthermore, means for protruding and fixing the wheel stopper have the disadvantage of interfering with getting on and off the vehicle.

The purpose of this invention is to eliminate the above-mentioned conventional problems, and the purpose of this invention is to prevent the movement of the mounted vehicle by the raised wheel stopper when the vehicle-mounted platform is moved or when the vehicle-mounted platform is left stationary at the parking position. ,
To provide a vehicle stop device for an on-vehicle platform in which a wheel stopper automatically lies down when getting on and off the vehicle so that the wheel stopper does not get in the way of getting on and off the vehicle.

The feature of this invention is that a hole is made on the top surface of the vehicle platform on which the vehicle is placed and moved, and a wheel stopper made of a plate-like member is movable up and down to cover this hole from above. The middle part of the operation arm is pivotally connected to the vehicle mounting base at a position below the top surface of the vehicle mounting base, and the tip of the arm hits the back side of the wheel stopper when the wheel stopper is raised to prevent the wheel stopper from lying down. The lower side of the wheel stopper is pivotally connected to the vehicle base, and a tension spring is installed on the lower side of the wheel stopper between the upper part of the wheel stopper and the tip of the operating arm, so that when the wheel stopper is raised, the tip of the operating arm An arm stopper that prevents the wheel from moving toward the upper part of the wheel stopper is provided on the wheel stopper at a position where the angle between the upper part of the wheel stopper and the tip of the operating arm is 90 degrees or more, and The present invention relates to a vehicle stop device for a vehicle platform in which a protrusion for rotating an operating arm is formed on the floor on which the vehicle platform is placed at a position where the vehicle is boarded or exited.

Next, this invention will be explained in detail based on the embodiments shown in FIG. 3 and below.

FIG. 3 is a plan view of the vehicle mounting base 15 according to the present invention. A pair of wheel stoppers 16 and a fixed stopper 16a are respectively arranged on the vehicle mounting base 15.
The fixed stopper 16a is a conventional device, and the fixed stopper 16a is a conventional device.
5 has a protruding car stopper fixed to it. The fixed stopper 16a and the wheel stopper 16 suppress the movement of the mounted vehicle when the vehicle mounting base 15 is moved. The two fixed stoppers 16a are arranged side by side on the left and right, but the two wheel stoppers 16 are shifted back and forth, so that one of the wheel stoppers 16 can be used depending on the wheel base of the vehicle.

4 to 7 are enlarged views of the wheel stopper 16, and the following description will be made based on these views.

Figures 4 and 5 (A-A' sectional view in Figure 4)
shows the state of the wheel stopper when it is raised.

The wheel stopper 16 is pivotally connected to the vehicle platform 15 by a hinge 17. This wheel stopper 16
There are three operating arms 19a, 19 in the middle of the lower surface of the
b, 19c are in contact with each other, and the wheel stopper 16
Two operating arms 19 located on one of the lower surfaces of the
A tension spring 20 is hung between the tips of the wheels a and 19b and the upper part of the lower surface of the wheel stopper 16. This tension spring 20 is connected to a guide pin 24 and a wheel stopper 16 fixed to the tips of two operating arms.
It is suspended under tension between the upper part of the body and is made of a coil spring. The force exerted by the tension spring 20 to move the upper portions of the two operating arms 19a and 19b above the wheel stopper 16 is blocked by the arm stopper 23, which will be described later.

Next, the middle parts of the two operating arms 19a and 19b and the middle part of the operating arm 19c arranged on the other side of the lower surface of the wheel stopper 16 are fixed through a shaft 21, and are integrated. 19
a, 19b, and 19c are configured to perform the same operation. Further, both ends of the shaft 21 are pivotally connected to side plates 22 that form part of the vehicle platform 15, respectively. As a result, the operating arms 19a, 19b, 19c fixed to the shaft 21 can be moved to the side plate 22.
It is rotatable relative to the The shaft 21 is
Also, it supports the load applied to the upper surface of the wheel stopper 16 via the operating arms 19a, 19b, 19c, and for this reason, the operating arms 19a, 19b,
Attach the arm stopper 1 to a position where the angle between the tip of the wheel stopper 19c and the top of the wheel stopper 16 is 90 degrees or more.
Place 6.

Figures 6 and 7 (BB' sectional view in Figure 6)
1 shows the state of the wheel stopper 16 when it is lying down.

A protrusion 26 is formed at a predetermined position on a predetermined floor 25 on which a vehicle mounting base 15 is placed, on which a vehicle gets on and off. The protrusion 26 is always located below the lower part of the operating arm 19 when the vehicle platform 15 is installed at a predetermined position on the floor 25 so that the wheel stopper 16 lies down.

The lower portions of the operating arms 19a, 19b, and 19c that contact the protrusion 26 are formed in an arc shape in order to smooth the undulations of the wheel stopper 16.

By configuring the vehicle stopper device for the vehicle platform as described above, the tension spring 20 disposed at the upper rear side of the wheel stopper 16 of the vehicle platform 15 is activated when the vehicle platform is moved and when the vehicle platform is left still at the parking position. ,
The tips of the operating arms 19a, 19b, and 19c are biased toward the top of the wheel stopper 16. The upper parts of the operating arms 19a, 19b, 19c whose tips abut against the back side of the wheel stopper 16 are connected to tension springs 2.
The arm stopper 23 prevents the wheel stopper 16 from moving upward due to the arm stopper 23. In addition, the upper part of the wheel stopper 16 and the operating arms 19a, 19
By configuring the upper portions of the operating arms 19a, 19b, 19c to be at an angle of 90 degrees or more with the arm stopper 23, the load of the vehicle applied to the wheel stopper 16 via the tire 18 is
Operating arms 19a, 19b, 1 from the top tip of c
The shaft 21 is attached to a shaft 21 which is fixed through the middle part of the wheel 9c, and since this shaft 21 is pivotally connected to a side plate 22 forming a part of the vehicle mounting base 15, it can support the load applied to the wheel stopper 16.

The wheel stopper 16 is automatically placed in a prone position by lowering the vehicle platform 15 onto a predetermined floor 25 on which a protrusion 26 is formed. That is, the operating arm 1
9a, 19b, 19c have a protrusion 26 at the bottom thereof.
It rotates in a direction approaching the upper plate of the vehicle platform 15. This rotation of the operating arm 19 is controlled by the side plate 22.
This is done around a shaft 21 which is pivotally connected to. This is because the tips of the operating arms 19a, 19b, 19c resist the biasing force received from the tension spring 20,
1 as a fulcrum. Therefore, by rotating the lower portions of the operating arms 19a, 19b, 19c in the direction approaching the upper plate of the vehicle mounting base 15, the tips of the operating arms 19a, 19b, 19c, that is, the back surface of the wheel stopper 16, Conversely, the abutting portion rotates downward of the vehicle platform 15. Then, the tension spring 20 stretches, and this tension spring 20
Due to the force (tensile force) that causes the wheel stopper 16 to contract downward, a downward force acts on the tip of the wheel stopper 16, causing the wheel stopper 16 to move toward the hinge 1.
7 as a fulcrum and rotates to the upper surface 15a of the upper plate of the vehicle platform 15. Thus, the wheel stopper 16 lies prone.

8 and 9 show another embodiment of the present invention, and the same reference numerals indicate the same components as in the previous embodiment. The difference in configuration from the above embodiment is that an operating arm 19d is newly arranged, and the operating arm 1
A roller 27 is provided at the lower tip between 9a and 19b and between 19c and 19d, and its operation is as follows.
The vehicle mounting base 15 is mounted on a predetermined floor 25 on which a protrusion 26 is formed.
When the roller 27 descends and lifts the protrusion 2
6 to move smoothly on the operating arm 19a, 1.
Smooth rotation of 9b, 19c, and 19d. And these operating arms 19a, 19b, 19c, 1
The rotation 9d is the rotation of the operating arm 19 of the first embodiment.
The lower portions of a, 19b, and 19c are smoother than if they were formed in an arc shape, and the undulations of the wheel stopper 16 are smoothed out.

As mentioned above, this invention relates to a wheel stop for a vehicle mounted on an on-vehicle platform, but the wheel stopper may be placed on either the front or rear side of the wheel or on the opposite side. Two of them may be placed on both sides. In this case, the effect of blocking the vehicle will be greater.
Further, it may be arranged on one of the left and right wheels on the front wheel side, and on the other of the left and right wheels on the rear wheel side. In addition, three or more wheel stoppers can be placed on the vehicle base to accommodate various types of vehicles with different wheelbases. One wheel stopper is formed long in the lateral direction and many operating arms are arranged. However, the left and right rear wheels may be blocked.

From the configuration described above, the following effects can be obtained from the present invention. In other words, when the vehicle platform carrying the vehicle is moved or when the vehicle platform is left still in the parking position, the upright wheel stopper prevents the vehicle from moving;
When getting on and off the vehicle, the car stop is automatically laid down by moving the vehicle platform onto a projection formed on a predetermined floor, so that the car stop does not interfere with getting on and off the vehicle. In particular, in the present invention, the wheel stopper is pivotally mounted on the top surface of the vehicle base so as to close the hole from above, and the pivot position is below the wheel stopper and below the top surface of the vehicle base. Because of that,
When the wheel stopper is lying down, the wheel stopper does not protrude significantly above the top surface of the vehicle mounting base. Therefore, since the wheel stopper does not get in the way when getting on and off the vehicle on the vehicle platform, getting on and off the vehicle can be done smoothly. In addition, in the present invention, the pivot position of the operating arm and the installation position of the tension spring are both located below the plate-shaped wheel stopper, so dirt and dust falling from the vehicle can be removed from the pivot position. This prevents it from adhering to the tension springs and ensures smooth operation at all times. Furthermore, in the present invention, only the operating arm, its pivot, the tension spring, and the arm stopper are disposed between the vehicle-mounted base and the wheel stopper, so the configuration is simple, and the parts and components are simple. It is possible to obtain a car locking device that reduces assembly costs, prevents the adhesion of dirt and dust, and has fewer failures.
