In conventional locks for desk drawers, etc., little consideration was given to the key insertion portion, and the device was generally exposed on the outside of the drawer. For this reason, there are security problems such as drawers with locks being easily targeted in the event of theft, regardless of whether they are locked or not, and it is desirable to simplify the drawer part of the desk and create a more streamlined design. Even if the key insertion part is conspicuous and has a negative impact on the design, or in an environment with a lot of fine dust, the oil film inside the lock will attract fine dust, making it difficult to operate smoothly.
Problems such as unlocking became difficult or impossible occurred.

In view of the above-mentioned problems, the present invention has been developed to make it possible to hide the key insertion part of a desk drawer, etc., and to convert between concealment and exposure with a single touch when locking and unlocking. The purpose of the present invention is to provide a cover device for a lock key insertion part, the gist of which is to provide a through hole for the key insertion part at one end in the length direction, and to provide a cover device that is continuous in the length direction at both ends in the remaining width direction. a convex piece protruding outward in the width direction, a convex locking piece integrally formed on the surface side and having a tip protruding obliquely in the direction of the through hole in the notch provided in the intermediate portion; a base plate having mounting legs protruding from the back surface; a frame portion having a size that can hide the base plate and forming a frame portion around the back surface except for one end corresponding to the through hole; A groove is formed on the inner surface of the linear portion of the frame portion in the longitudinal direction so as to be slidable in the length direction of the straight portion of the frame portion, and a groove is formed on the inner surface of the straight portion of the frame portion in the longitudinal direction so as to be slidable in the length direction of the straight portion of the frame portion. The cover plate has an abutting wall surface at the top thereof, and a recess in which a mountain-crossing slope is formed at a predetermined position in the middle of the cover plate.

Next, details of the present invention will be explained based on illustrated examples.
A typical implementation of the cover device for the lock key insertion part of a desk drawer according to the present invention, which is applied and attached to the key insertion part 1 of the lock H attached to the desk drawer G in the front view of the desk F in FIG. An example is shown in Fig. 2 showing a state in which the key insertion part 1 is exposed by sliding the cover plate C in the length direction of the base plate B, and Fig. 2 showing the back side of the cover plate C and base plate B in the disassembled state. As illustrated in FIG. 3, a through hole D for a key insertion part having an inner diameter through which the key insertion part 1 of the lock H can be inserted is formed at one end in the length direction, and a drawer is provided on the back side B'. The leg E for attaching to an object to be attached, such as the illustrated example, is a bottomed cylinder 2, and the inner circumference of the cylinder 2 is screwed with a wood screw 3 as shown in Fig. 4, an example of a fixing method. A base plate B having two mounting legs protruding from each other having a diameter and a surface that can be fixed to the base plate B, and a base plate B having a size that allows the base plate B to be concealed and located on the surface side of the base plate B. The base plate B is fitted externally or internally so as to be slidable in the length direction, and in the illustrated example, convex strips 4, 4 continuous in the length direction are fitted outward in the width direction of the base plate B at both ends in the width direction of the base plate B. Opposed grooves 5, 5 that are protruding from the projections 4, 4 and slidable by fitting with the protruding strips 4, 4.
are provided on the back side at both ends in the width direction, and by fitting and inserting the convex strips 4, 4 into the grooves 5, 5, the base plate B can be slidably removed in the length direction. Although not shown, protruding strips are provided in the longitudinal direction of both ends in the width direction so as to protrude outward in the width direction, and opposed grooves are provided on the surface of the base plate so that the protruding strips can fit and slide. It is constructed of a cover plate or the like in which the convex strip is fitted into the concave groove.

Therefore, the cover device A of the lock key insertion portion of a desk drawer according to the present invention is attached to the base plate B with respect to the key insertion portion 1 of the lock H attached to the drawer G to be attached as shown in FIG. 4, for example. A through hole 6 formed in the drawer front plate G' with the mounting leg E shown in FIG. If you insert the cover plate C into the base plate B and attach it with the wood screws 3 so that the back side B' of the base plate is in contact with the surface of the drawer front plate G' to be attached, the cover plate C will be the same length as the base plate B. Since it is fitted externally or internally so as to be slidable in the left and right directions in FIG. If it can be hidden and slid to the right, the key insertion part 1 can be exposed and a key can be inserted, and the mutual conversion between concealment and exposure can be achieved by simply sliding the cover plate C in the left and right direction. This makes it possible.

Here, it goes without saying that the front surface 1' of the key insertion part is installed in a desk drawer G or the like with a length that does not protrude forward from the surface of the base plate B. If the screw 3 is used also as the wood screw 3' for attaching the lock, the number of man-hours and the number of parts can be reduced. The mounting leg E shown as the cylindrical body 2 in the illustrated example may have another convex shape, and in this case, the convex leg is embedded in the front surface of the drawer, which is the mounting surface, by adhesive bonding, press-fitting, etc. It is extremely easy to install.

In this example, a notch 7 is provided between the mounting legs E and E of the base plate B, and the key is inserted into the notch 7 on the surface side of the base plate B, that is, on the cover plate C side. A convex shape is provided on the base plate B with the tip 8' protruding slightly from the surface of the base plate B obliquely in the direction of the through-hole D for use, and integrally molded with synthetic resin or the like and elastically biased due to the material properties. Locking piece 8
and a recess having an abutting wall surface 9 at a predetermined position on the back surface C' of the cover plate at least at both ends in the length direction, and a mountain-crossing slope 10 having a gently convex curved surface on both sides at a predetermined intermediate position inside the recess. It is said to be associated with place 11. That is, cover plate C
When the key insertion part 1 is slidably fitted onto the base plate B and the key insertion part 1 is exposed as shown in FIG. The concave flat surface 11' on the side contacts the tip 8' of the convex locking piece and applies a slight pressure to the base plate B side, and the slope 10 on the side of the key insertion hole D side contacts the tip 8' of the convex locking piece. By contacting the rear part 8'' of one side, the cover plate C is kept stationary and the rear surface of the cover plate C is kept stationary.
C' constitutes the recess wall forming the recess 11, and the abutment wall surface 9 on the key insertion hole D side is connected to the abutment wall surface 9 with the tip 8' of the convex locking piece. The positional relationship is such that when the key insertion part 1 is exposed by the abutment, it becomes a stopper that restricts the sliding of the cover plate to the right in the illustrated example. At the same time, when the cover plate C is slid to the left in the illustrated example to completely hide the key insertion part 1, the tip 8' of the convex locking piece is at the other end of the back surface C' of the cover plate. It is located at the starting end of the slope 10 on the side and is connected so as to come into contact with the recess plane 11'' on the other end side, and when the cover plate is in the concealed state, it is provided to protrude from the other end of the back surface C' of the cover plate. If the inner wall surface 13 of the frame portion 12 is made into a stopper that the other end portion 14 of the base plate abuts against the inner wall surface 13 and limits further sliding to the left in the illustrated example, the position of the cover plate C can be changed. Even if you do not visually check the cover plate and slide it so that it does not fall off the base plate B, for example, you can place your finger on the hook part shown as 15 in the figure for moving the cover plate provided on the surface of the cover plate. By applying pressure and pushing/pulling, it is possible to hide and expose the key insertion portion 1 without paying too much attention.Here, the elastically biased convex locking piece 8 and The locking and positioning function of the cover plate C in combination with the abutment wall surface 9 is the same even if the respective plates are reversed, that is, a convex locking piece is formed on the cover plate, and the abutment wall surface is formed on the base plate side. In addition, other means such as convex minute warts and grooves (not shown) may also be used to prevent slippage and position.
Base plate B through which the key insertion part 1 is inserted or exposed
If a projecting edge 16 is provided on the back side so as to be continuous with the periphery of the through-hole D for the key insertion section provided at one end of the key insertion section, positioning can be made easily by simply positioning the key insertion section 1 within the projecting edge 16. Therefore, the work of attaching the cover device A to the desk drawer G can also be streamlined.

In addition, if the brand name, manufacturer name, or model name is engraved or colored on the surface of the cover plate C, it will not only have an advertising effect, but depending on its form as an emblem, it can also have the effect of creating a sense of luxury. The cover plate and base plate shown above are each obtained by integral molding of synthetic resin or the like and can be manufactured extremely easily.

The cover device for the lock key insertion portion of a desk drawer according to the present invention as described above is such that the cover device for the key insertion portion that appears on the surface side of the front plate of the lock attached to the drawer front plate is provided at one end in the longitudinal direction. A through hole for the key insertion part is provided, and a convex piece that is continuous in the length direction is provided at both ends of the remaining width direction so as to protrude outward in the width direction. a base plate integrally formed with a convex locking piece whose tip protrudes obliquely in the direction of the through hole, and further provided with mounting legs protruding from the back surface; A frame portion is formed around the back surface except for one end corresponding to the hole, and a concave groove is positioned on the front surface side of the base plate and slidably engages with the convex piece so as to be slidable in the length direction of the base plate. A cover plate having a recess formed on the inner surface in the lengthwise direction of the straight portion of the frame portion, further having abutting wall surfaces at both ends in the lengthwise direction at a predetermined position on the back side, and a slope over a mountain formed at a predetermined intermediate position inside the cover plate. Therefore, it is possible to convert the lock insertion part of a lock installed in a desk drawer, etc. into a concealed state or an exposed state, and by keeping the key insertion part in a hidden state during normal times, it is preferable for crime prevention. In addition, the aesthetic appearance of the desk as a whole can be expected to be improved, and when the lock is locked or unlocked, the key insertion portion is exposed so that the key can be inserted, and the key insertion portion slides on the cover plate. It is possible to convert between the concealed state and the exposed state with a single touch by just moving the key, and since the through hole for the key insertion part and the mounting leg are integrally formed, installation is extremely easy. .

In addition, in the concealed state where the cover plate is slid along the length direction of the base plate to hide the front surface of the key insertion hole, the inner wall surface of the frame portion at the longitudinal end of the cover plate is hidden. Abuts on the other end of the base plate,
On the other hand, in the exposed state where the front surface of the key insertion hole is exposed, the tip of the convex locking piece of the base plate hits the abutting wall surface on the key insertion hole side in the recess of the cover plate, and the tip of the convex locking piece of the base plate hits the abutting wall surface on the key insertion hole side of the recess of the cover plate, In addition to regulating the sliding movement of the cover plate, the protruding tip of the convex locking piece passes through a slope provided in the middle part of the recess during the change between the two states, so that both states are reliably maintained. Can be maintained.

Furthermore, since a convex locking piece is integrally formed on the front side of the notch provided in the middle of the base plate and has a tip protruding obliquely toward the key insertion hole, the base plate can be easily disassembled. When assembling the cover plate, simply connect the end of the cover plate that does not have the frame part to the convex piece and concave part of the base plate, starting from the end opposite to the side where the through hole for the key insertion part is made. By slidingly engaging the grooves and pushing in, the rear end of the cover plate slides past the convex locking piece of the base plate, and the tip of the convex locking piece enters the recess of the cover plate. The assembly work is extremely easy.
