Abstract

PURPOSE:To promote handling efficiency of a shackle lock and, at the same time, to facilitate the storage and carrying of the shackle lock by folding the approximately U-shaped shackle lock used for preventing a two wheeled vehicle from burglary compactly without separating a lock lever from a lock main body. CONSTITUTION:A lock main body 2 having an insertion port 2b inserting an insertion end 1b of one end of a lock lever 1 in an undrawable manner is connected to the other end 1c of the lock lever 1 formed in a U-shape with a connecting section 2a so that they can be bent each other. A bendable hinge section 1a is provided to the middle part of the lock lever 1.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock generally called U-shaped shackle lock which is mainly used for the prevention of theft of motorcycles such as motorcycles and bicycles.

[0002]

2. Description of the Related Art Conventionally, as a lock of this kind, as shown in FIG. 5, insertion ends 3a, 3a at both ends of a pipe 3 formed in a substantially U shape are connected to a lock body 4 formed in a straight rod shape. The pipe 3 is fixed to the lock body 4 by being inserted into the insertion ports 4a, 4a formed on one side, or the pipe 3 can be bent so that it can be bent by a connecting tool 6 as shown in FIG. The substantially U-shaped pipe 5 is provided with insertion ends 4a, 4a formed in the lock body 4 with insertion ends 5a, 5a at both ends thereof similarly.
There was a device in which the pipe 5 and the lock body 4 were connected by inserting the pipe 5 into the lock body 4.

[0003]

In the above-mentioned conventional lock, since the former is constructed such that the U-shaped pipe and the lock body are separated when unlocking, it is necessary to store them together in a bag or the like when carrying them. However, it is cumbersome and its size is regulated by the external dimensions of the U-shaped pipe, so that it has a problem of being bulky. In the latter, the U-shaped pipe is folded into about half size with a connecting tool so that it does not become bulky when stored, but the pipe and lock body are separated when unlocking. However, it has to be stored in a bag or the like, which causes a problem of troublesome handling. The present invention aims to solve the problems that these conventional locks have.

[0004]

According to the present invention, one end of a U-shaped locking rod is connected to one end of the locking rod via a pivotable connecting portion with which the other end of the locking rod is undetachably engaged. The above-mentioned problem is solved by providing the hinge part which is bendable in the middle of the lock rod while being attached.

[0005]

[Function] The connecting portion of the lock body and the lock rod functions to rotate the lock body with respect to the lock rod, and insert and remove the insertion end of the lock rod into and from the insertion opening of the lock body to perform the locking and unlocking operation. At the same time, it acts so as to bend the lock main body toward the lock rod during storage.
Further, the hinge portion of the lock rod functions to bend the lock rod formed in a substantially U shape so as to reduce the outer dimension thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the drawings. FIG. 1 is an explanatory view showing an unlocking operation according to the embodiment, and FIG. 2 shows its stored state. As shown in the figure, the folding lock of the present invention comprises a substantially U-shaped lock rod 1 which is bendably connected by a hinge portion 1a and a lock main body 2 which is pivotally attached to one end of the lock rod 1. Become.

The lock rod 1 is made of metal or synthetic resin and is formed into a solid or hollow pipe shape. One end of the lock rod 1 is inserted into an insertion port of a lock main body described later and is locked so as not to be removed. The insertion end portion 1b is used as the insertion end portion 1b.

The lock body 2 is made of metal or synthetic resin, and is pivotally attached to the other end 1c of the insertion end 1b of the lock rod 1 at the connecting portion 2a. An insertion port 2 into which the above-mentioned insertion end 1b can be inserted on the upper surface near the tip.
b is formed. A hook plate (not shown) that locks the insertion end 1b in the insertion opening 2b so that the insertion end 1b cannot be removed.
Is provided so as to be retractable, and the hook plate is fixed or driven by a cylinder mechanism (not shown). Two
Reference numeral c indicates a key hole into which a key for operating the cylinder mechanism is inserted.

The cylinder mechanism may be of a magnet type for locking and unlocking by utilizing the magnetic force of a magnet, or may be an ordinary key type cylinder or dial type cylinder.

Next, the folding procedure of the folding lock of the present invention having the above construction will be described. First, as shown by the solid line in FIG. 1, the insertion end portion 1b of the lock rod 1 is pulled out into the insertion opening 2b of the lock body 2. When the locked state in which the lock is impossible is released by driving a cylinder mechanism (not shown) installed in the lock body 2 with a key (not shown) inserted in the key hole 2c, the insertion end 1b and the lock are released. Since the engagement with the hook plate in the main body 2 is released, the lock main body 2 pivotally attached to the lock rod 1 has the connecting portion 2
It is possible to rotate the tip (left side in the figure) downward about the center of a. Therefore, first, when the lock body 2 is moved below the insertion end portion 1b as shown by the chain double-dashed line in FIG. 1, the insertion end portion 1b of the lock rod 1 is pulled out from the insertion opening 2b of the lock body 2. It will be possible to move freely. Therefore, the lock rod 1 that is bendably connected by the hinge portion 1a
To the position indicated by the chain double-dashed line so that the lower end of the lock rod 1 is expanded, and then the lock body 2 is rotated in the opposite direction to the above, and the lock rod 1 is likewise moved from the hinge portion 1a in the opposite direction. When folded, the folding lock of the present invention is compactly folded as shown in FIG.

In the above, after the lock is unlocked, the lock body is first rotated downward, but this operation is automatically performed by the urging force of the spring installed in the insertion opening along with the unlocking operation. Good as a matter.

FIG. 3 shows another embodiment of the present invention. In this example, the lock body 2 is attached to the mounting end surface of the lock rod 1 by the mounting shaft 2d inserted into the end 1c of the lock rod 1. 360
The lock rod 1 is attached so as to be freely rotatable, and is connected by a hinge portion 1a so that the lock rod 1 can be bent only inward from the locked state. Therefore, in this example, when the lock rod 1 is stored, the lower end of the lock rod 1 cannot be opened and the lock body 2 cannot be rotated in the direction in which the front end (left side in the drawing) of the lock rod 1 approaches the lock rod 1. After that, as shown in FIG. 4, the lock main body 2 rotated below the insertion end 1b is first rotated about the mounting shaft 2d to shift the relative position to the insertion end 1b, and then the tip thereof. The lock rod 1 is rotated in a direction approaching the lock rod 1. After rotating the lock body 2 in this manner, the lock rod 1
When inwardly bent from the hinge portion 1a, the folding lock of this embodiment is also compactly folded like the folding lock of the above-described embodiment shown in FIG.

As described above, in the folding lock of the present invention,
It is possible to store the lock rod and the lock main body compactly without separating the lock rod and the lock main body while unlocking the required external dimensions when locking.

[0014]

As described above, the folding tablet of the present invention is
Although it has the same dimensions as a conventional shackle lock when locked and is used in the same manner, it can be folded compactly as a unit without separating the lock body and the locking rod when storing, so it can be used as a lock. It has an excellent effect that it can be easily handled and stored and carried without impairing its original function.
