Abstract

PURPOSE:To levitate a tire from the ground without requiring another's hand by forming a vehicular jack stand in such a way that one end thereof is rotatably fitted at a vehicle body and the other end can be locked at the ground so as to levitate the vehicle body in association with the movement of a vehicle. CONSTITUTION:At the time of levitating the left rear wheel T of a vehicle V, the lock pin 23 of a jack stand 20 in the non-operated state is pulled out so as to pull an inner body 22 out of an outer body 21, and the lock pin 23 is engaged with a hole in the operated state so as to fix the inner body 22 at the outer body 21. The pin bolt 22 of the jack stand 20 is then fitted into the left rear fitting hole 12b of a body side frame 10, and the tip 24 of the inner body 22 is grounded in such a way as to be locked at the ground. When the vehicle V is moved backward in this state, the jack stand 20 is rotated around the pin bolt 22 as its axis, and the left rear wheel T of the vehicle V is placed in the levitated state. At this time, the jack stand 20 is in contact with stopper 14b so as to hold the left rear wheel T in the levitated state.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a jack stand for a vehicle.

(Prior Art) Conventionally, devices for lifting vehicle tires off the ground include:
A pantograph type jack as shown in FIG. 5 is known.

In FIG. 5, the engaging part 1a of the jack handle 1 is engaged with the retaining part 2a of the horizontal threaded part 2, and when the jack handle 1 is rotated by a human hand, the threaded part 2a rotates. However, the tray portion 3 of the receiver rises (or descends).

Therefore, by disposing this jack between the lower surface of the chassis of the vehicle (2) and the ground G, the tires (not shown) of the vehicle (2) can be lifted off the ground.

(Problems to be Solved by the Invention) However, in the conventional pantograph type jack described above, since the jack handle 1 is rotated by a human hand, there are problems in that the work load is large and the work time is long.

SUMMARY OF THE INVENTION In view of the above conventional problems, an object of the present invention is to provide a vehicle jack stand that can lift vehicle tires off the ground without relying on human hands.

(Means for Solving the Problems) In order to achieve the above object, the present invention has one end rotatably attached to the vehicle body, and the other end is formed so as to be latched to the ground, so that the vehicle body can be moved by the power of the vehicle. It was made to float.

(Function) According to the above configuration, when the vehicle moves, the other end is locked to the ground and rotated about the one end, so that the vehicle is in a floating state.

(Example) Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing one embodiment of a vehicle jack stand according to the present invention, FIG. 2(a) is a side view showing the side frame of FIG. 1, and FIG. 2(b) is a Line A- in Figure 2(a)
3(a) is a side view showing the jack stand of FIG. 1, and FIG. 3(b) is a top view of the same.

The side frame 10 has an opening formed upward and a substantially U-shaped cross section, and is formed longitudinally along between the front and rear tires T of the vehicle V.
A flange portion 11 for fixing to the lower surface of the chassis of the vehicle V is formed above the flange portion 11 . Note that this side frame 10 is fixed to both sides of the vehicle V, and the drawing shows
The left side frame 10 of the vehicle (2) is shown.

Holes 12a and 12b are formed in the outer side wall of the side frame 10 for rotatably attaching the jack stand 20 near the front and rear tires T of the vehicle V, respectively. Figure 2 (
As shown in b), the weld nut 13 is fixed. Also, on the lower wall of the side frame 10, stoppers 14a and 14 for restricting the rotation of the jack stand 20 are provided.
b is formed to protrude laterally.

The jack stand 20 is roughly composed of a longitudinal outer body 21 and an inner body 22 that is slidable along the inside of the outer body 21 in order to adjust the length of the jack stand 20. 22, the length when the inner body 22 is pulled out from the outer body 21 is the length between the mounting holes 12a, 12b and the ground G.
is formed so that it is longer than the distance between.

At one end of the outer body 21, there is a weld nut 3 in the mounting hole 12a (or 12b) of the side frame 10.
A pin bolt 22 that can be screwed into is attached to the outer body 21, and a lock pin 23 for fixing the inner body 22 to the outer body 21 is attached to the other end of the outer body 21.

The inner body 22 has a hole (not shown) that engages with a lock pin 23 when the inner body 22 is pulled out from the outer body 21 and the jack stand 20 is extended (in use). A hole (not shown) is formed that engages with the lock pin 23 when the jack stand 20 is shortened (not in use) when stored, and the tip 24 of the inner body 22 is configured to lock onto the ground. The side surface shape is approximately J-shaped.

Next, the operation of the above embodiment will be explained with reference to FIG.

FIG. 4 shows a case where the left rear wheel T of the vehicle V is lifted.
The inner body 22 is identified to the outer body 21 by removing the lock pin 23 and pulling out the inner body 22 from the outer body 21, and engaging the lock pin 23 in the hole in the used state.

Next, attach the bottle bolt 22 of the jack stand 20 to the left rear mounting hole 12b of the side frame 10, and then attach the inner body 22 as shown in FIG. 4(a).
The tip 24 of the terminal is grounded so that it is fixed to the ground.

In this state, when the vehicle (2) is moved backward, the jack stand 20 rotates around the pin bolt 22, and since the jack stand 20 is longer than the distance between the mounting hole 12b and the ground G, as shown in FIG. 4(b). As shown in , the left rear wheel T of the vehicle V is in a floating state.

In this case, the jack stand 20 comes into contact with the stopper 14b, so that the left rear wheel T is maintained in a floating state.

In addition, when the left rear wheel T is grounded on the ground G, the vehicle V
Or, if you want to lift the two rear wheels at the same time, attach the two jack stands 20 to the holes 12 at the rear of the side frame lO.
Just attach it to b. Furthermore, the same applies to the case where either or both of the front wheels of the vehicle (2) are lifted off the ground.

Although the above embodiment has been described using a four-wheel drive vehicle as an example, it is of course applicable to vehicles with other drive systems.

(Effects) As explained above, in the present invention, one end is rotatably attached to the vehicle body, and the other end is formed so as to be latched to the ground, so that the vehicle body can be floated by the power of the vehicle. It is possible to raise the vehicle's tires off the ground without relying on it.
