Description

[Detailed description of the invention] <Industrial field of application> The invention can be applied to padlocks, bolt locks, bag locks, etc., and can be applied to storage case doors,
This card lock has various uses such as opening bags and desks, and the lock member is moved by a sliding plate, and the sliding plate is moved by inserting a card.

<Prior Art> Various slide mechanisms for conventional push-button locks have been proposed, and the present applicant has also proposed one. For example, it is disclosed in Japanese Utility Model Application Publication No. 61-32465. The slide mechanism of this pushbutton lock consists of a plurality of pushbuttons, a plurality of engagement pins, a slide plate, and a locking member that directly or indirectly interlocks with the slide plate. By moving the engagement pin and maintaining or releasing the engagement between the engagement pin and the slide plate, movement of the slide plate is prevented or enabled, and the locking member is locked or unlocked in conjunction with the movement of the slide plate.

<Problem to be solved by the invention> However, in the slide mechanism of the push-button lock having the above structure, the push button that presses and operates the engagement pin that engages with the slide plate is always specified. As the frequency of use increases, the top of the pushbutton often becomes discolored or discolored compared to other pushbuttons that are not used. As a result, a third party could see through the operating procedure of the push button, and the mechanism lost its merit as a lock sliding mechanism. A card lock has also been proposed, but its mechanism is complicated and operation is troublesome.

<Means for solving the problems> The present invention has been devised in order to solve the above problems, and as a result, the operating procedure is structured so that it cannot be discovered from the outside even after long-term use, and it is easy to operate. This is how I discovered a unique card lock.

The structure includes a fixing plate having a plurality of pin-fitting holes arranged in parallel, a pin-fitting hole formed opposite to the pin-fitting hole of the fixing plate, and a card engaging part formed therein. A slide plate that is elastically supported so that it can be restored, and a plurality of different types of engagement that are rotatably elastically attached to the pin insertion hole of the fixed plate and that engage and disengage as appropriate with the pin insertion hole of the slide plate. A pin, a locking member that moves directly or indirectly by the slide plate, and a fitting hole into which the engagement pin is fitted, and the engagement pin is rotated as appropriate to engage with the slide plate. This card lock is characterized by comprising a card which is released and which moves the sliding plate by pushing the sliding plate. Further, the engagement pin is made of resin and integrally molded with a spring piece, and can be rotatably and elastically attached to the pin insertion hole of the fixing plate, and can be formed into various shapes. The design of other members can be changed in the same way.

<Function> In this invention, when a card is inserted into the card insertion gap, if the card is the desired one, the engagement pin and the slide plate are disengaged, that is, the card rotates the desired engagement pin and engages the engagement pin. By disengaging the slide plate, the slide plate can be slid, and by pushing the slide plate, the locking member interlocking with the slide plate moves and is unlocked, making the unlocking operation easy. be. When the card is removed, the slide plate and lock members return to their original state.

<Example> Figures A, B, and C show the fixing plate of the present invention;

-Y schematic cross-sectional view. The fixed plate 1 is a rectangular body made of resin, into which a slide plate and a locking member are attached. Reference numeral 2 denotes a pin insertion hole into which an engaging pin is elastically attached, and a plurality of pin fitting holes (four pins) are arranged in parallel. 2a is a pin bearing portion, 2b is a protrusion and spring body receiving portion, and 2c is a through hole. 1a is a peripheral protrusion, 1b is a guide protrusion of the locking member, and 1c is a screw hole. By providing many pin insertion holes, many different types of locks can be made.

Figure 2 A, B, and C show slide plates, A is a plan view, B is a schematic cross-sectional view of A along XX, and C is a Y-Y of A.
It is a schematic cross-sectional view. The slide plate 3 is a rectangular body molded with resin, and is provided so that it can be restored by sliding on the fixed plate.
The pin fitting holes 3a are formed as through holes. An engagement pin is inserted into this insertion hole. 4 indicated by a dotted line is an engagement pin. A protrusion is fitted into 3b. 3c is a protrusion formed on the left side and the rear excluding the front part, and the rear protrusion functions as a card engaging part.

3A, B and C show a plurality of different types of engagement pins of the present invention, A is one type of side view, B is various side views, and C is a plane of the engagement pin shown in A and B. It is a diagram. 4 and 5 are different types of engagement pins molded with resin. These engagement pins are a pair of left and right protrusions 4a, 5a.
are formed at different locations, and the shaft portions 4b, 5b and the spring bodies 4c, 5c have the same shape. Protrusion 4
A is formed on the upper part of the main body, and protrusion 5a is formed on the lower part of the main body. The shaft parts 4b, 5b are housed in the pin bearing part 2a of the fixed plate, and the spring bodies 4c,
5c is supported by the spring body receiving portion 2b, is rotatably elastically supported in the pin fitting hole of the fixed plate, and is appropriately engaged with and disengaged from the pin fitting hole of the sliding plate.

4A, B, and C show a lock member that is moved directly or indirectly by the slide plate in the same direction as the slide plate, and the metal plate is bent. A shows a plan view, B shows a XX sectional view of A, and C shows a YY sectional view of A.

The lock member 6 has downward bent portions 6a on both sides, and a key portion 6b in the center which is shorter than the bent portions 6a on both sides. 6c indicated by a dotted line is an engagement lock member that engages with the key portion 6b, and the engagement hole 6c' engages with the key portion 6b to represent a locked state. The locking member 6 is assisted in movement by the guide protrusion of the fixing plate and moves smoothly.

FIG. 5 shows a plan view of the card. The card 7 only needs to have the size and thickness of a cash card, business card, etc., and is made of resin with a certain degree of hardness. A hole 7a for fitting an engaging pin is formed in this card as appropriate. In other words, by pushing down one of the plurality of different types of engagement pins with a card, the engagement pin is rotated and pressed down, and the other types are kept in the same state without being pushed down. As a result, all the engagement pins are disengaged from the slide plate, and the slide plate becomes movable.Furthermore, by pushing the card engaging portion 3b of the slide plate with a card, the slide plate is locked. Move it to the 6th side. Then, push the lock member to move it. Therefore, if the combination of the card with the desired insertion hole 7a and the corresponding desired engagement pin is satisfactory, the engagement of the slide plate will be released and the slide plate can be slid. Cards cannot slide on the slide plate.

FIG. 6 shows a schematic cross-sectional view of the assembled state using the above-mentioned members. The fixed plate 1 incorporates a slide plate 3 locking member 6, a spring 8 for biasing the locking member toward the slide plate, and is provided with a lid 9. 10 is a card insertion slot. The slide plate 3 is elastically supported by a spring 8 via a locking member so that it can be restored. The slide plate 3 can also be restorably supported by directly attaching a spring. Reference numeral 9a is a hole into which the aforementioned engagement locking member 6c is inserted, for example. Since the protrusion 4a of the engagement pin 4 is located at the card insertion slot, the slide plate is movable. When the engaging pin is pushed down by the card and rotated down to the position indicated by the dotted line, the projection 4a is located in the pin insertion hole 3b, so that the slide plate cannot be moved.

FIG. 7 shows a difference from the one shown in FIG. 6 in that the engagement pin is different. Since the protrusion 5a of the engagement pin 5 is located at the position 3b of the pin insertion hole, the slide plate cannot be moved. When the engaging pin is pushed down by the card, it becomes the state shown by the dotted line, the projection 5a is removed from the position of the insertion hole 3b, and the slide plate is movable.

FIG. 8 shows a state in which the slide plate is moved by the card and the lock member is moved at the same time, with both members moving against the force of the spring 8. In this case, the lock member 6c and the lock member 6 inserted through the hole 9a remain in the unlocked state as shown in the figure.

FIG. 9 shows a case body 11 that houses the fixing plate and the like. 11a is a hole through which the engagement locking member 12 is inserted, for example. If the case body is made into a flat box shape, the lid 9 of the fixed plate 1 may be omitted. 12a is a key part. When this engaging lock member is unlocked by the spring body 12b, it is automatically separated from the lock member by the spring pressure.

The present invention is not limited to the above-mentioned embodiments and explanations of design change ideas, but also the technical idea of moving a sliding plate using a card and pushing the locking member with the sliding plate to release the locked state. Included in the modification.

<effect> The card lock of the present invention has the following effects.

(1) The lock can be unlocked by simply operating the slide plate using a card, making it easy to operate with one hand.
Easy to use even for children.

(2) Since the card, like a cash card, is always carried by the user, there is no need to worry about the code on a push-button lock being seen through.
