Embodiment FIG. 1 is a side view showing a part of an embodiment of the stand device of the present invention, and FIG. 2 is a left side view of a bicycle equipped with the stand device of the present invention. In the present invention, similar and corresponding parts to those in the prior art are given the same reference numerals.

As shown in these figures, the stand device 20 of the present invention is installed, for example, on the left side of a bicycle, and has a leg 3 and a leg 3.
A spring 8 that elastically biases the legs in the opening direction (the direction in which the legs spring up backward), and a lock shaft 4 provided at a position offset from the swing axis (hereinafter referred to as the main axis) 2 of the legs 3. One end is connected to the locking member 5 which is angularly displaced around and prevents the leg portion 3 from swinging in the opening direction, and the mounting piece 22 provided at the free end of the locking member 5 via the mounting piece 22. The wire wire 21 includes a wire wire 21, an operating handle 23 to which the other end of the wire 21 is connected, and means 26 for keeping the operating handle 23 in a locked state.

The leg portion 3 is swingably attached via the main shaft 2 to the base body 1 which is fastened to the rear wheel axle 18 with a nut 19.

The spring 8 has one end anchored to a spring support protrusion 6 bent from the base 1 toward the side of the vehicle body, and the other end anchored to a locking member 5.
However, in this embodiment, the axis of the spring 8 is always at a position that biases the leg 3 in the opening direction. That is, the axis of the spring 8 is located behind the lock shaft 4 when the leg portion 3 is in the open state (the leg portion 3 is in the upright position L), and is located above the lock shaft 4 when the leg portion 3 is in the open state. The spring support protrusion 6 also serves as a regulating member for limiting the swing range of the leg 3 rearward.

A guide roll 24 is provided between the locking sheath portion 9 and the lock shaft 4 in the lock member 5, and the guide roll 24
is in contact with the downward guide portion 25 of the base 1 and is rotatable. This guide roll 24 makes the swinging of the leg portion 3 smooth, reduces the load applied to the main shaft 2, and prevents wear of the main shaft 2.

Further, as a means for smoothing the rocking of the leg portion 3, a locking groove 15 provided on the base body 1 and a locking pin protruding from the upper part of the leg portion 3 and sliding facing the locking groove 15 are provided. 17 are configured.

The attachment piece 22 has its blind end fixed to the distal end of the locking member 5, and one end of the visibility wire 21 is connected to the other end.

This wire 21 passes through a first kite pulley 33 supported at the rear of the rear lower frame 31 of the vehicle body, a second guide pulley 34 supported at the lower part of the rear upper frame 32 of the vehicle body, and swings to the upper part of the rear upper frame 32 of the vehicle body. The other end is connected to the free end of an operating handle 23 whose base end is movably attached.

The means 26 for keeping the operating handle 23 in a locked state includes:
As shown in the rear view of the vicinity of the bicycle saddle in FIG. 3 and the plan view of the saddle 27 in FIG. At the left end of the rod 38, the rod 3
8, a pair of thrusts 1 to 3 bearings are mounted across the operating handle 23, and a plate spring member 40 is mounted on the left end thereof. The operating handle 23 is raised forward as shown in the side view of FIG.
By moving forward in the direction of arrow A (FIG. 4), bypassing the lateral bulge 28 formed at the rear of the saddle 27, the operating handle 23 comes into contact with the lateral bulge 28. When they come into contact with each other, movement to the rear is prevented, resulting in a locked state. As the operating handle 23 is operated, the locking member 5 is pulled upward via the wire 21 and the attachment piece 22, as shown in FIG. abutting and the legs 3 are locked relative to the base body 1.

To move the operating handle 23 in the direction of arrow A,
By moving the operating handle 23 forward while pulling it towards the left of the bicycle, the operating handle 23 is displaced towards the left against the elastic force of the leaf spring member 40, and the front of the lateral overhang 28 is moved forward. It is possible to move to In addition, the operation handle 2
3 in the direction of arrow B, it may be operated in the same manner.

The operating mode of the stand device 20 described above will be explained.

While the bicycle is running, the lock member 5 is in an open state, as shown in FIGS. 1 and 2, and the leg portion 3 is flipped up rearward about the main shaft 2.

Next, when the legs 3 are placed in the closed state, by placing the tips of the legs on the ground and moving the bicycle backwards, the legs 3 stand and the chest contact portions 13 of the legs 3 The cutting and raising piece 11 of the base body 1 is brought into contact with the rear end surface 12, the operating handle 23 is raised forward from the horizontal state, and the operating handle 23 is further moved forward from the lateral projecting portion 28 of the saddle 27. By locking, the lock member 5 is angularly displaced forward around the lock shaft 4 in accordance with the arrow C (FIG. 6), and the leg portion 3 is placed in a locked state.

To release the locked state, move the operating handle 23 in the direction of arrow B in the reverse order to the above, and release the engagement of the operating handle 23 with the saddle 27. As a result, the locking of the leg portion 3 by the locking member 5 is released. The legs 3 are constantly biased by the elastic force of the spring 8, so just by lightly pushing the bicycle forward, the legs 3 can easily swing around the main shaft 2, allowing the bicycle to travel (111). The operation handle 23 returns to its original horizontal state. The locking member 5 is displaced rearward by an angle of l\, so that the lower end surface of the locking sheath portion 9 comes into contact with the front surface of the leg portion 3 and is locked. When the leg portion 3 operates as described above, the guide roll 24 slides on the guide portion 25 of the base body 1, and the locking pin 17 is guided by the locking groove 15, so that the leg portion 3 operates smoothly. In the negative state of the leg 3, the leg 3 is kept in place with its abutting surface 16 abutting against the spring support projection 6 of the base body 1.

The length of the operating handle 23 can be adjusted according to the height of the saddle 27, for example, by screwing.

Note that in the stand device for the right side of the bicycle, a leg (not shown) that is continuous and integrated with the left side is pivotally supported via a main shaft to a base for the right side that is symmetrical to the left side. There are no locking members, attachment pieces, wires, operating handles, etc., and the other end of the spring is supported on the side of the leg.

The stand device according to the present invention may be equipped with a locking member or the like on the right side of the bicycle.

The stand device according to the present invention is also applicable to two-wheeled vehicles other than bicycles.

Effects of the Invention As described above, the present invention allows the locking member to be locked by operating the operating handle that can be locked to the saddle, so it can be easily operated even from the side opposite to the side where the locking member is attached. Since there is no need to use the foot to lock the shoe as in the conventional method, there is no chance of soiling or damaging the footwear.

Since the legs are given elastic force by springs in the direction of opening, when the lock is released, the bicycle can be opened by simply pushing the bicycle forward, and the bicycle can be ridden.

As described above, according to the stand device of the present invention, the user can park or start the bicycle without using his or her feet at all.
