Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to locking of a steering wheel and a braking device of a vehicle.

[0002]

2. Description of the Related Art Conventionally, locking of a vehicle is mainly performed by individually attaching things such as a steering wheel and a spoke portion of a wheel, and a wire lock or the like is additionally used to enhance the prevention of theft.

[0003]

The locking of vehicles is often done externally, and bicycles and the like are mainly simple ones that lock through the spokes of the wheels, and usually only one wheel is used for locking. You have to lock it after getting off the bicycle,
It can be easily broken, stolen or neglected, but it is an object of the present invention to solve the problems at the forefront.

[0004]

A base cam (13) having lock grooves (15a) and (15b) is fixed to an upper portion of a frame handle portion (26), and a bearing (11) and a bearing receiver (12) are placed on the lower case ( A leaf spring (6) and a pair of knock pins (7) are provided in 4). Further, the movable cam (8) and the movable plate (10) are connected to the plate shaft (1).
4) Attach the manual lever (19) to the end which becomes a series by inserting, and attach the key cylinder (5a) and the oil pump (21) to the upper case (2) and pass the brake wires (1a) and (1b). By tightening and fixing the handle post (24) with the fixing nut (25), the brake and the handle are simultaneously double-locked to solve the problem.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Since the main body is provided at the lower part of the handle, turning on the key (5b) in the riding posture while the vehicle is in the riding position prepares for locking, and the handle is turned to contact and rotate, and the brake is pulled by the elliptical drop of the cam. Maintain pressure and lock. In places where there is no space, the lock can be arbitrarily locked by activating the manual lever (19), and the knock pin (7) can be inserted into one of the lock grooves (15a) and (15b) and locked at the same time. With it, you can safely park your bicycle on slopes and slopes.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A base cam (13) is press-fitted into a frame handle portion (26) and fixed integrally with a frame so as not to be knocked or welded, and a main body is fixed to an upper case (2) and a lower case (4). A strong material that can be integrated with the metal fitting (3) and is not easily broken is preferable. A key cylinder (5a) is attached to the upper case (2).

In the lower case (4), a cam spring (9) is inserted into a movable cam (8) and normally acts to push up so as not to interfere with the base cam (13). A series is formed through the shaft (14), but individually movable.

A knock pin (7) is mounted on a leaf spring (6) for locking a handle above the movable cam (8). Then, the brake wires (1a) and (1c) with the wire stopper (1c) attached are passed through the wire holes (16a) and (16b) passing through the upper case (2) the movable plate (10) and the lower case (4) to fix the case. It is fixed integrally with the bracket (3).

The bearing (11) and the bearing tray (12) are inserted between the integral body and the base cam (13) integral with the frame handle (26) in advance, and the handle post (24) is inserted. Tighten in (25). At this time, the handle post (24) is integrally fixed using a key groove, a knock pin, or the like, so that the movement is synchronized with the movement of the handle.

When the key (5b) is turned off by the above assembly, each part is in a free state without interfering with each other, but when the key (5b) is turned on, the key cylinder (5a) rotates and the leaf spring (6) is pressed down to knock the pin (5). 7) can be guided downward.

The movable cam (8) is also lowered by the knock pin (7) which is further pushed down, and comes to a position where it interferes with the base cam (13). At that time, the lower part of the movable cam (8) comes into contact with the movable plate (10) to form a series.

When the handle is turned from the above state, the movable cam (8) turns around the edge of the elliptical portion of the base cam (13), so that it is further pushed downward by the elliptical drop, and the plate shaft (14) faces the fulcrum. The movable plate (10) is pushed upward, and by raising the wire stopper (1c), the brake wire (1b) on the cantilever (30) side can be pulled up to lock the brake. In short, the lateral rotation of turning the steering wheel is arbitrarily changed to a vertical movement, and other methods such as gear driving may be used instead of the cam.

When there is no space for turning the handle, the manual lever (19) is lowered by the gear (17) of the movable cam (8) and the gear stopper (18) attached to the key cylinder (5a). It is also possible to engage the brake lock arbitrarily.

The handle is not locked when the brake is locked by the manual lever (19), but when the handle is turned, the saw-shaped lock groove (1) in the base cam (13) is provided.
Since 5a) and (15b) face left and right outwards, the steering wheel is turned but not returned and locked.

Further, in an example of use for a hydraulic brake which is seen with a motor or the like, an oil pump (21) is provided so that a brake hose (22) is pushed by pushing the pump.
The oil can be sent to the brake lock, and it can be used together with the front wheel oil and the rear wheel wire.

Further, after the handle is turned off and the brake is locked, a knock pin (7) attached to the leaf spring (6) being pushed downward is provided with a lock groove (15a), (15b) in the base cam (13). The handle can be locked either.

It is also possible to use a commercially available wire suspension fitting (20), and the joint (2) connected to the key cylinder (5a) when the key (5b) is turned off.
Through 7), the movable plate (28) is raised to push up the tip of the wire suspension fitting (20), so that it is in a free state. When the key (5b) is turned on, the movable plate (28) is lowered to be in a lockable state.

By pulling the brake lever (29) connected to the brake wire (1b) in the lockable state, the brake wire (1b) is pulled up and the brake can be locked. That is, the vehicle is in a one-way state and travels from the brake wire (1b) toward the brake wire (1a) but locks in the opposite direction. However, since the elongation of the wire is returned and the lock of the cantilever (30) is somewhat loose, it is necessary to maintain the lifting force at all times. By turning the handle, the knock pin (7) is lowered and the handle can be locked.

[0019]

According to the combination lock device of the present invention, the front and rear wheels and the steering wheel are locked by a single key operation at hand while riding the vehicle, so that theft prevention is enhanced and the same effect as that of the automobile side brake is achieved, thereby ensuring safety. It can park bicycles, and considerable demand is expected.
