Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a wire lock for preventing theft of the wheels by locking a wire that is laid across between the front and rear wheels of a bicycle, and for storing the lock in a bicycle frame. The present invention relates to a bicycle anti-theft lock in combination with the bracket.

[0002]

2. Description of the Related Art Even if a bicycle is locked with a wire lock on a tree, a utility pole, etc., in the case of a sports bicycle, the front and rear wheels can be separated from the main body with one touch, so that only the wheels are stolen. is there. Therefore, a wire lock including a long wire that can be stretched across both wheels has been proposed. The wire has a spiral curl,
When not in use, it shrinks naturally so that it does not bulge.

[0003]

When riding a bicycle, the long wire lock is passed through a proper position of the bicycle frame, and the tip fitting is locked to the lock body and stored on the frame.

However, the heavy lock body (4) and the terminal fitting
Since (5) is only engaged with each other and is not fixed on the frame, there is a problem that it swings while the bicycle is running and hits and damages the frame. The present invention, the lock body (4)
The purpose of this invention is to clarify a wire lock in which the terminal fitting (5) can be fixed and stored on the frame.

[0005]

The bicycle anti-theft lock of the present invention has a lock hole (43) at one end of a wire (6) wound in a spiral shape.
Attaching a lock body (4) having a wire lock formed by attaching a terminal metal fitting (5) to the other end of the wire (6) so as to lockably engage with the lock hole (43) of the lock body (4), Bicycle frame
The bracket (2) is formed in combination with the bracket (2) protruding from the (1), and the bracket (2) is fitted to the end of the terminal metal fitting (5) in a lockable manner and opened to the side edge of the bracket. A notch (25) and a protrusion (26) lockably engaged with and disengaged from the lock hole (43) of the lock body (4) located adjacent to the notch and closing the lateral opening of the notch. Cage, cutout (25) with terminal fittings
After fitting (5), insert the protruding piece (26) into the lock hole (43) of the lock body (4), lock the lock body (4) to the bracket (2), and install it. The side open portion of the notch (25) in which the () is fitted is closed by the lock body (4), and the terminal fitting (5) can be prevented from coming out.

[0006]

[Operation and effect] The wire (6) is laid across both wheels through the bicycle frame (1), and the terminal fitting (5) is locked to the lock body (4). As a result, even if the wheel (16) is removed from the frame (1), it is not possible to carry the wheel alone and it is possible to prevent the wheel from being stolen.

When riding a bicycle, remove the wire (6) from both wheels (16) (16) and the frame, fit the terminal fitting (5) into the terminal fitting fitting notch (25) of the bracket (2), and lock body. The projecting piece (26) of the bracket (2) is engaged with and locked in the lock hole (43) of (4).

The lock body (4) covers the terminal fitting (5) to prevent the terminal fitting from coming out of the fitting notch (25), that is, the lock body (4) and the terminal fitting on the bracket (2). (5) can be fixedly held. Since the wire (6) has a spiral curl, the wire (6) naturally spirals and shrinks, allowing for compact storage.

[0009]

[Embodiment] FIG. 1 shows a vertical pipe (11) of a bicycle frame (1).
Part of the wire lock (3) and the wire lock (3) as a frame
The bracket (2) for fixing and holding is shown in (1). FIG. 3 shows a use state of the wire lock, and FIG. 2 shows a stored state of the wire lock.

A vertical split groove hole (not shown) is formed in the rear portion of the upper end of the upright pipe (11), and a pair of fastening pieces (14) and (14) are provided on both sides of the groove. As is known, saddle (13)
Fit the seat post (12) attached to the vertical pipe (11), insert the bolt into the bolt insertion hole (15) (15) of the tightening piece (14) (14), tighten the nut and tighten the seat post (12). ) Can be fixed at any height.

In the embodiment, the above-mentioned tightening pieces (14) (14) are
It also serves as a mounting member for attaching the bracket (2) for fixing the wire lock, which will be described later.

The wire lock (3) is lockably engaged with and disengaged from the lock body (4) at one end of the wire (6) having a spiral winding tendency and the lock hole (43) of the lock body at the other end. It is constructed by attaching terminal fittings (5). The wire (6) is covered with a synthetic resin tube over the entire length.

The terminal fitting (5) has a taper portion (51) whose diameter is gradually reduced toward the front end side, and a retaining flange (52) is projected at the tip of the taper portion.

The lock body (4) is an oval-shaped flat case (41)
A boss (42) is provided at one end of the wire and the wire (6) is attached to the boss.
The base end of is inserted and fixed. Keyhole on the other end of the case (41)
(44) is provided, and the lock hole (4) into which the retaining flange (52) and the taper portion (51) of the terminal fitting (5) are fitted on the peripheral surface of the case.
3) has been formed.

In the lock hole (43), a lock claw (not shown) that engages and disengages with the retaining flange (52) of the terminal fitting (5) is capable of appearing and retracting in the insertion and removal passage of the terminal fitting and a spring (see FIG. It is deployed by urging it in the pop-out direction (not shown). Insert the key (not shown) into the keyhole (5) and turn it, the lock claw will
It sinks from the insertion / removal transition path of (5) and the terminal fittings from the lock hole (43)
(5) can be removed.

The bracket (2) has parallel wall plates (22) and (23) projecting from both side edges of the bottom plate (21) in the longitudinal direction, and one wall plate (23) is attached to the bicycle frame (1). The arm piece (28) is protruding.
A bolt insertion hole (29) is formed in the mounting arm piece (28), and the mounting arm piece (28) is tightened together with the tightening pieces (14) and (14) with bolts and nuts to the frame (1). Fixed.

A notch (20) into which the boss (42) of the lock body (4) is fitted is opened at the upper end of one wall plate (22) of the bracket (2),
The other wall plate (23) is provided with a lock body fitting notch (24) into which the case (41) of the lock body (4) fits.

The wall plate (23) is provided with a protruding piece (26) adjacent to the lock body fitting notch (24) and fitted in the lock hole (43) of the lock body (4). A claw piece (27) that engages and disengages with the claw piece in the lock hole (43) is formed at the tip of the (26). Notch for fitting the lock body
A notch (25) for fitting a terminal metal fitting is formed in the (24) by opening the bottom on the side of the projecting piece (26). The notch (25) is continuous with the lock body fitting notch (24) and is laterally open.

Then, through the bicycle frame (1),
The wire (6) is laid across the front and rear wheels (16) (16), and the terminal fitting (5) is engaged and locked in the lock hole (43) of the lock body (4). This allows the wheels from the frame (1)
Even if (16) is removed, the wheels cannot be carried around, and the wheels can be prevented from being stolen.

When riding a bicycle, remove the wire (6) from the wheels (16) (16) and the frame (1), and taper the terminal fitting (5) to the notch (25) for fitting the terminal fitting of the bracket (2). Fit the tip of the part (51) into the lock hole (43) of the lock body (4) and the bracket (2).
The projecting piece (26) is engaged and locked.

The end fitting (5) has a retaining flange (52) at the tip.
Is not caught in the edge of the notch (25) and does not come off in the axial direction, and the lock body (4) covers the terminal metal fitting (5) to prevent the terminal metal fitting from coming out upward from the fitting notch (25). That is,
The lock body (4) and the terminal fitting (5) can be fixedly held on the bracket (2).

Since the wire (6) has a spiral curl, the wire (6) naturally spirals and shrinks, and can be stored compactly.

The present invention is not limited to the configuration of the above embodiment, and various modifications can be made within the scope of the claims for utility model registration.
