"The lower lock rod and the upper lock rod are superposed on the center of the lock box, and a roller is arranged at the lower end of the upper lock rod so that the lock lever can be moved up and down. The L-shaped steel plate to be pushed is pressed by a spring so that one end of the steel plate slides on the central cutout of the lower lock rod and the cutout arranged on the upper part of the lower lock rod intersects at right angles. Immediately after being fitted into the recessed part of the hook support rod to be equipped, the hook support rod should be automatically slid and fixed to the left outer side by the spring, and at the same time, the upper lock rod and the lower lock rod should be connected to each other. An automatic bicycle having a protrusion for pushing up a steel plate so that the husband can automatically move independently, and a U-shaped locking claw that can be bent in a horseshoe shape at the lower end of the lower locking rod so as to engage with it. If you insert the key into the lock housing and rotate it half way to the right in the locked state with the lock claws engaged, the hook support rod will be on the right. Sliding down to fit the recessed part of the hook support rod into the recessed part of the lower locking rod, and the lower locking rod moves downward and restores independently of the lower locking rod, and the locking claw is opened to remove the bicycle. According to the above, the upper lock rod is restored and polymerized again with the lower lock rod.

As described above, the automatic bicycle antitheft device has a complicated and diverse mechanism inside the lock casing.

“Problems to be solved by the invention” By the way, recently, in order to park many bicycles in a parking lot for bicycles, etc. in order to park a lot of bicycles indoors in an orderly manner In many cases, wheel mounting bases and wheel fixing locks are provided at equal intervals along the wall to regulate the parking position. In order to frequently access many bicycles, it is necessary to avoid the inconvenience of operating the wheel lock with the husband and wife's key to lock and unlock it, and speed up the access operation. Since the lock is provided for each bicycle, the wheel lock that is installed in the parking lot does not require a lock key, and it only needs to have the function of fixing the wheels in place. is there.

In view of this, the present invention has been devised to provide a wheel lock that has a simple mechanism that allows the front wheels to be easily inserted and removed when the bicycle comes in and out, and that is easily attached to the rear wall portion.

"Means for solving the problem" As a means for achieving the above-mentioned object, in order to perform the opening and closing operation of both locking claws that mesh the front wheel from the left and right by the impact force that presses the lock plate with the front wheel of the motorcycle, The lock plates, which pivotally support the base ends of both lock pawls to both sides, are inserted into the lock box, and both lock pawls are pressed from the outside by the both side walls of the lock box to rotate to cause a closed engagement. The lock plate is inserted and retracted by being urged by an ammunition machine that is intruded into the bottom of the lock box, and the bottom of the triangular groove in plan view is bent to form a recess on the upper surface of the base of the lock plate. The recessed portion, the groove bottom surface at the four sides of the groove is formed in a stepwise upward slope inclined surface, and a step is provided at each of the apex angle portion, both bottom corner portions and the recessed portion, and the locking step portion is formed. A circular guide groove with a hole is formed, the rear end hook of the hook is connected to the center of the bottom wall of the lock box, and the front hook is engaged with the circulation guide groove of the lock plate. The slide lock is circulated along with the circulation guide groove in response to the lock plate moving in and out, and the front end hook is locked at each locking step of the recess and the apex corner to stop sliding. There is a leaf spring attached to the top wall of the lock box that presses the front end hook of the connecting hook from the circulation guide groove so that it does not separate from the circulation guide groove. A wheel lock configured to open and close.

[Operation] In the wheel lock according to the present invention, the lock box and the lock plate are connected to each other by connecting hooks so that they can be retracted, and both lock claws pivotally supported on both sides of the lock plate are retracted. It is an interlocking open / close in response to the operation, and it is performed by the engaging position of the front end hook part of the hook bar and the triangular guide groove on the upper surface of the lock plate that connects the locking means of the lock plate in the retracted state and the protruding state. The movement of the engagement position is performed by guiding the triangular guide groove,
Further, a low step portion for locking the front end hook portion is formed at a predetermined position of the guide groove, and the lock box and the lock plate are fitted by locking the front end hook portion at the low step portion at the predetermined position. The degree is fixed, and the open state and the meshed state of both lock claws are fixed.

The mechanism of interlocking the lock box, the lock plate, and both lock claws will be described below.

When the wheel lock is not parked, the lock plate protrudes forward from the lock box and both lock pawls are open so that the front wheel of the motorcycle can be inserted. When the front wheel is pressed against, the lock plate will immerse into the lock box, and at the same time, both lock claws will squeeze inward toward each other by pressing the outside of both lock claws to rotate and close them. Then, both tips mesh with each other to clamp the front wheel.

At that time, the front hook of the connecting hook, which was located at the top corner of the triangular guide groove, slides along the left side of the guide groove and moves to the left bottom corner. The locking force of the machine causes the lock plate to move a little forward, and at the same time, the front end hook moves to the recess and falls to the lower step of the groove to stop catching, so the locking state of both lock claws is maintained and locking is performed. Be seen.

Next, when unlocking to pull out the two-wheeled vehicle, pressing the front end of the lock plate with the front wheel moves the lock plate slightly into the lock box,
The front end hook moves from the depression to the right bottom corner. Then, when the front wheel is retracted, the lock plate projects from the lock box due to the accumulated force of the ammunition, both lock claws open, and at the same time the front end hook slides along the right side of the guide groove and at the apex corner. Stops and the tip falls into the low step and engages. In the open state of both lock claws, the connecting hook bar pulls and supports the lock plate by resisting the accumulating force of the ammunition, and prevents the lock plate from further projecting. The inserted state of is maintained.

At the time of this operation, the front end hook of the connecting hook is formed on both sides of the triangular guide groove on the four sides (there are recesses in the bottom side, so that the groove has four sides). In addition, since the formation of the low step portions at the four points of the apex angle portion, both bottom corner portions and the depression portion prevents the backward movement, the sliding direction is limited to the same advancing direction. Therefore, cyclic sliding in the same direction is repeated.
