Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lock device used as a lock for closing a sliding glass surface such as a show window.

[0002]

[Prior art]

 Conventionally, a lock device as shown in the present invention has been generally used as a lock for closing a sliding glass surface such as a show window. However, the conventional device is of a type in which the protrusion protruding from one end of the lock body to the outside is short, and the engagement width between the lock body of the lock device and the base body that engages is also short, so that the glass surface is completely closed. In particular, when locking the sliding glass door, pulling the sliding glass door forward from the front sliding part creates a space where you can insert your hand. There was a problem that something inside the case was stolen.

[0003]

[Problems to be solved by the device]

 The present invention has been devised to solve the above-mentioned conventional problems.For example, when locking a sliding glass door or the like, one side of the glass door is moved from the front sliding part. It is an object of the present invention to provide a locking device that can be locked properly by creating a space for inserting a hand by pulling it forward and preventing things inside the case from being stolen from the space. .

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is configured as follows. That is, both ends in the width direction are each bent inward to form a rail portion 2, and the rail portion 2 has a saw-toothed blade-shaped locking portion 3, and the locking portion 3 is engaged with the base body 1. Locking / unlocking portion 5 that can be locked / unlocked, a lock main body 4 that is regulated by the rail portion and guides the movement of the locking / unlocking portion 5 in the longitudinal direction of the base body 1, and rises from one end of the lock main body 4 and further outside And a projecting piece 6 protruding to the side.

[0005]

[Action]

 According to the present invention, a protrusion 6 is provided which rises from one end of the lock body 4 and further extends outward. Therefore, the protrusion 6 can be prevented from moving not only in the pulling direction but also in the direction orthogonal to the pulling direction, so that an appropriate locked state can be achieved.

[0006]

【Example】

 The present invention will be described below based on a preferred embodiment. In the figure, reference numeral 1 indicates a substrate. As shown in FIG. 1, the base body 1 is formed in a long and thin substantially rectangular shape, and both ends thereof are bent inward in the width direction, whereby rail portions 2 and 2 are formed. Has been formed.

At one end side or both end sides of the rail portions 2 and 2, a saw-toothed engagement portion 3 is provided over substantially the entire direction of the rail portions 2 and 2. Next, reference numeral 4 indicates a lock body. The lock body 4 has an engaging portion (not shown) that engages with the locking portion 3 and can be locked and unlocked, and the locking and unlocking is a substantially cylindrical shape that is operated by a key to lock and unlock. It has a part 5.

From the lower end of the locking / unlocking part 5, the locking / unlocking part 5 fitted in the rail parts 2, 2 of the base body 1 and having the engaging part moves in the longitudinal direction of the rail part 2. A guide portion 9 having a substantially rectangular shape for guiding the operation is provided integrally with the locking / unlocking portion 5. Further, on one end side of the lock main body 4, there is provided a substantially semicircular projecting piece 6 which rises from this one end and further largely projects outward from the upper end of the rising portion 14 in the horizontal direction.

The rising portion 14 is covered with a covering material 15 such as a rubber member because the contact surface such as a sliding door collides with the rising portion 14. In the above, the use state of the lock device according to the present invention will be described. First, the base 1 is attached to an installation place such as a sliding door to be locked. Next, the lock body 4 is inserted between the rail portions 2 and 2 from one side of the attached base body 1 and slid in the longitudinal direction of the base body 1.

Then, the engaging portion of the locking / unlocking portion 5 provided on the lock body 4 is brought into a state capable of engaging with the engaging portion 3 of the base body 1. Then, the locking positions of the guide part 9 and the locking / unlocking part 5 fitted into the rail parts 2 and 2 of the base body 1 are determined, and the final locking condition is obtained in this state. The unlocking operation of the lock device according to the present invention can be performed by inserting a key into the keyhole 7 and rotating the key.

FIG. 2 shows another embodiment of the present invention. That is, the present invention is used for the sliding sash 10 as understood from FIG. When attached to the sliding sash 10 in this manner, the protrusion 6 of the lock body 4 is formed with a notch 8 on the surface of the sliding sash 10 that faces the vertical frame 11, and the protrusion 8 is projected into the notch 8. By inserting the piece 6, it is possible to obtain a strong closed state.

That is, it is impossible to easily remove the pull-back sash 10 by inserting the protruding piece 6 of the lock body 4 into the notch 8 of the vertical frame 11. Next, FIG. 3 shows still another embodiment. For example, the locking device according to the present invention is attached to a door that opposes the single swing door 12 in order to lock the open side end of the single swing door 12.

Then, the lock body 4 fitted in the base body 1 is moved to the side of the single swing door 12 as much as possible, and the projecting piece 6 is extended to the outside of the end portion of the single swing door 12, whereby the single swing door 12 is opened. The operation can be closed and locked. The present invention is also characterized in that such a locked state (locked state in a direction orthogonal to the mounting direction) can be obtained.

Further, FIG. 4 shows another embodiment of the present invention, in which the locking device of the present invention can be attached to the lock of the glass door 13 of the show window case. Thus, the so-called sliding glass door 13 of the show window case can be locked tightly. That is, in the lock device of the present invention, the protruding piece 6 is formed so as to project greatly outward, and therefore, even if the person in the show window case is to be stolen, the glass door 13 in the shape of a fold is pulled toward you. Even so, the structure is such that it is not possible to secure a space enough to allow a hand to be inserted into the case because it is obstructed by the projecting piece 6.

As can be seen from FIG. 1 and the like, in the lock device according to the present invention, the saw blade-like locking portion 3 is formed on the rail portions 2 and 2 in a considerable length in the longitudinal direction of the base body 1. Therefore, the lock body 4 is moved rightward in FIG. 1 so as to be flush with the end surface of the base body 1, and the protrusion 6 is made to have a considerable length so as to project outward. Is something that can be done.

Such a configuration is also a major feature of the present invention.

[0017]

As described above, the present invention has the above-mentioned configuration. In the case of the lock device according to the present invention, the protrusion provided on the lock body is formed so as to largely project outward, so that when the lock device is used as a lock on the window of a window as shown in FIG. 1 or 4. However, even if the protruding piece is not in the direction of the sliding direction and is in a direction orthogonal to the sliding direction, that is, even if the sliding door of the show window is forcibly pulled forward, it does not slide in the sliding portion of the sliding glass door. I can't make a void.

Therefore, the hand cannot be put in the window case. Further, the present invention can also be used for a sliding sash, and in such a case, a notch is provided on the facing surface of the vertical frame of the sliding sash, and the protrusion is inserted in the notch. By doing so, stronger locking can be expected.
