[0002]

[Prior art]

 Conventionally, this type of drawer lock device is generally formed by a lock lock having a keyhole on the front plate surface of the drawer.

[0003]

[Problems to be solved by the device]

 However, with such a structure, since the keyhole is arranged on the surface of the front plate of the drawer, there is a problem that the keyhole inevitably interferes with the design of the front plate of the drawer.

[0004] Also, conventionally, it has been thought that the keyhole of the lock device of the drawer is located on the front plate surface, but I tried to break that image, but I have provided the one that has broken the image so far. The current situation is that it has not been done.

In view of the above-mentioned inconveniences and the like, the present invention proposes, in a drawer that at least the upper end surface of the front plate is exposed to the outside and is movably mounted back and forth inside the drawer housing, the drawer lock. It was devised to overcome the image that the keyhole of the device is located on the front plate surface, and to provide a lock device for the drawer formed to have a sufficient degree of design freedom.

[0006]

[Means for Solving the Problems]

 This invention relates to a drawer in which at least an upper end surface or a side surface of a front plate is exposed to the outside and which is mounted inside a drawer storage body so as to be movable back and forth. By providing the lock lock of the drawer having the keyhole on the end surface or the side surface, the above-mentioned problem is solved.

Further, in the structure, the lock lock is formed to prevent the latch of the drawer from being released by locking the lock, thereby solving the above-mentioned problems.

[0008]

[Action]

 In the drawer lock device according to the present invention, at least the upper end surface or the side surface of the front plate is exposed to the outside, and the drawer is mounted in the drawer housing so as to be movable back and forth. To operate the lock provided on the front part, insert the key into the keyhole on the top or side of the front plate.

The operation can be performed without any problem because at least the upper end surface or the side end surface of the front plate is exposed to the outside, and the front plate has no keyhole on its surface.

In that case, since the lock lock is formed so as to perform the lock operation by blocking the release of the drawer latch, if the lock lock has a latch mechanism, the lock is locked at that portion. The lock device can be configured only by attaching a lock, and it is not necessary to particularly form a locking portion for locking the drawer storage body on which the drawer is mounted.

【Example】

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

That is, reference numeral 1 shown in the drawing is a front plate of the drawer H, and the front plate 1 is made of, for example, a steel plate and has a hollow inside.

This drawer H is, as shown in FIG. 1, a drawer storage in the form of a horizontal box in which at least the upper end surface 1c and the back surface 1b of the front plate 1 are exposed to the outside and the opening is provided horizontally. It is formed so that it can be moved back and forth inside the body B, and the upper edge of the opening of this drawer storage body B is made into a large chamfered notch-shaped finger insertion recess B1. When the drawer H is pulled out from the mounted state, a finger is inserted into the finger insertion escape portion B1 and the upper end portion of the front plate 1 is picked up to perform the pulling out work.

An operation recess 2 is formed at the center of the front plate 1 in the lateral direction from the upper end surface 1c to the upper end of the back surface 1b, and the drawer H is inserted into the drawer storage B in the operation recess 2. A latch operation body 3 for releasing a latch that locks the front plate 1 in a mounted state is arranged.

A key hole 22 of a lock lock 21 housed in the upper end of the front plate 1 is exposed in the vicinity of the operation recess 2 on the upper end surface 1c of the front plate 1.

The latch operating body 3 is formed of a plate material that is bent so that its longitudinal cross section is substantially hat-shaped, and is substantially attached to a shaft 4 that is horizontally installed in the front plate 1. An intermediate portion is axially supported and is arranged so as to be swingable in a seesaw shape in the vertical direction. An upper end portion thereof is an operating portion 3a and a lower end portion thereof is an operating portion 3b.

The operation portion 3a of the latch operation body 3 is arranged so as to be exposed at the bottom portion 2a of the operation recessed portion 2, and is bent in a substantially crank shape and pivotally supported toward the operation portion 3b. The lever 5 is held by sandwiching the operating portion of the lever 5.

Further, the operating portion of the lever rod 5 is formed so as to contact the latch operating rod 6.

Therefore, when the operating portion 3a of the latch operating body 3 is pressed toward the surface 1a in the plate thickness direction of the front plate 1, the latch operating body 3 swings to swing the lever rod 5, and thereby the latch lever 5 is swung. The operating rod 6 moves to unlock the latch.

Then, when the pressing of the operating portion 3a is released, the operating portion 3a is also operated by utilizing the force that the latch operating rod 6 returns to its original position by the spring (not shown) provided on the latch side. It returns to the original position.

On the other hand, the lock lock 21 is formed so as to perform its locking operation by preventing the release of the latch of the drawer H. In practice, as shown in FIG. 2 and FIG. In order to prevent the swinging of the body 3, it is formed by advancing the blocking rod 23 of the lock lock 21 between the operating portion 3b and the steel plate forming the back surface 1b of the front plate 1. The blocking rod 23 is configured to be moved forward and backward by inserting a key (not shown) into the key hole of the key hole portion 22 and turning the key.

The positions of the lock locks 21 may be provided on the side end surfaces of the front plate 1 when the side end surfaces and the back surface side end portions are exposed to the outside.

On the other hand, in the latch operating body 3, the operating portion 3a is coated with a flexible material such as a rubber material, or a covering material 11 made of a material having a surface feeling with the surface plate material of the drawer H. Are formed by coating. As a result, the operating portion 3a of the latch operating body 3 can be pressed from the surface of the covering material 11, and the surface shape of the covering material 11 is formed to have a wavy shape with small unevenness in the cross section. It is mounted by fitting it into the front plate 1 as appropriate.

Further, the covering material 11 of the latch operating body 3 is also arranged along the cross-sectional shape of the upper end portion of the front plate 1 of the drawer H.

Needless to say, the lock device for the drawer according to the present invention is not limited to the above-described embodiment, and may be provided on the side end surface of the front plate 1 or any type of device. Even if it is a latch mechanism, it may have a structure in which the blocking rod 23 is advanced so as to prevent the latch release operation, and it has a latch release blocking function by being installed along with the latch mechanism. Anything will do as long as it is.

[Effect of device]

 According to the present invention thus formed, at least the upper end surface 1c or the side surface of the front plate 1 is exposed to the outside and the drawer H is movably mounted in the inside B of the drawer housing so as to be movable back and forth. By providing the lock lock 21 of the drawer H having the key hole on the upper end face 1c or the side face at the upper end or the side end, the operation of the lock lock 21 provided at the upper end of the front plate 1 can be performed in the front direction. Since the key can be inserted by inserting the key into the upper end surface 1c of the plate 1 or the keyhole arranged on the side surface, the operation can be performed without any problem because at least the upper end surface of the front plate 1 is exposed to the outside. Since there is no keyhole on the surface 1a of the front plate 1, the image that the keyhole of the lock device of the drawer H is located on the front plate surface can be overcome, and sufficient design freedom can be obtained. it can.

In that case, since the lock lock 21 is formed so as to perform the lock operation by blocking the release of the latch of the drawer H, if the lock lock 21 has a latch mechanism, the lock lock 21 is provided in that portion. The lock device can be configured only by attaching the lock lock 21, and it is not necessary to particularly form a locking portion for locking the drawer housing B on which the drawer H is mounted, and the structure is very simple. be able to.

As described above, according to the present invention, it is possible to break the conventional image that the keyhole of the drawer lock device is located on the front plate surface, and to obtain a sufficient degree of design freedom.
