Description

[Detailed Description of the Invention] The present invention relates to a key chain storage case suitable for use as a security device for managing each room of a general building, tenant building, hotel, various exhibition halls, etc. using respective keys.

Conventionally, various systems have been proposed for this type of security device, and generally a centralized control system is used.

In other words, the keys for each room are collected in a control room, and the alarm device is automatically turned on using a fixed arrival key or a manual operation to indicate the absence.

Therefore, as an example of a method using the key itself, a magnet is embedded in the key chain, and a detection element such as a reed relay is provided for each key on the key suspension panel, and the detection element is activated by each key chain. There is something I did.

However, in the case of such means, depending on the correspondence between the magnet of the key chain and the detection element, that is, the orientation of the key chain, the detection element may not operate properly, or there are various other problems including maintenance issues. Some shortcomings have been recognized.

The purpose of the present invention is to propose a new and rational key chain storage case that can overcome the above-mentioned drawbacks.

A specific example of the present invention will be explained below with reference to the drawings.

FIG. 1 is a perspective view for explaining a key chain that is inserted into and removed from the storage case.

In the figure, 1 indicates a key, and 2 indicates a holder, which is made of a rectangular plate made of synthetic resin, for example, and the key 1 is connected to one end of the plate via a wire ring 3, at a predetermined position from the other end, that is, the free end. A recess 4 having a depth of, for example, an ellipse in the width direction is formed on the front and back surfaces.

Fig. 2 is a partially cross-sectional plan view showing an example of the key chain storage 7-s according to the present invention; Fig. 3 is a partially longitudinal side view;
The figure is also a front view, and in the figure, 5 is the storage case as a whole, 6a and 6b are side plates facing each other and have a U-shaped cross section, and Ta and 7b are the upper and lower plates installed between the side plates. The upper and lower plates 7a and 7b form a holder insertion part 8 (slot part) at a predetermined interval, and the key chain 2 is inserted through the right opening 9 of this insertion part 8. facing the opening 9, the upper and lower plates ra, 7
b is provided with a symmetrical sloped surface 9' that opens upward and downward, making it easy to insert the key chain 2.

The upper and lower plates 7a and 7b are each provided with side plates 10, and are attached vertically facing each other, and bent pieces 11 are formed on both sides of each right end.

As is clearer from the illustration, this storage case 5 has a rectangular outline that is wider in the plane than in the upper and lower sides, and has the above-mentioned side plates 6a.
, 6b and the upper and lower plates 7a=7b are all made of pressed sheet metal parts and have the same shape, and are assembled as a pair.

In this example, the L-shaped mounting plate 12 is fixed to the upper and lower outer surfaces of the bent piece 11 on one side formed at the right end of the upper plate 7a and the lower plate 1b. For example, a microswitch 13 is installed as a detection means, and its actuator 14 is pushed into the right end notch 15 of the upper and lower plates 7am 7b, facing the slot portion 8, and inserted, as indicated by the two-dot chain line 14' in FIG. The end of the holder 2 is pressed against it in the operating state shown by the solid line, and at the end of this pressing, one end of the holder is brought into contact with one surface of the plate 12. There is.

That is, after obtaining this state, the key chain 2 is placed inside the storage case 5.
The presence of the microswitch 13 is detected, and the various setting circuits connected to the microswitch 13 are also turned on at the same time, as in the past.

However, this is more than just an example of a microswitch detection element.

By the way, it goes without saying that such a detection state must be stably maintained.

Therefore, in this embodiment, the holder 2 is placed on the side of the upper plate 1a.
Retaining means are provided which engage the recess 4 (see FIG. 1).

This means that shaft grooves 16 are formed at predetermined positions on both side plates 10 of the upper plate 7a from the respective upper edges.Since the lower plate is also made of the same material, the grooves are preliminarily formed in the same way as the upper plate. Both ends of the roller shaft 18, which rotatably supports a row 217 made of a resin material, are loosely fitted into the shaft groove 16, and the spring support shaft 1 is inserted into the both side plates 10 at the left position, for example.
9 is inserted into the support shaft 19, and a coil banner 20 having a pressing part 20' extended in a U-shape is wound around the support shaft 19, and the pressing part 20' moves the roller shaft 18 toward the slot part side. The roller 17 is biased so that the recess 4 on one surface of the holder 2 and the roller 17 are engaged within a recess 21 formed in the upper plate 7a corresponding to the roller 17.

In this way, the keychain can be inserted and removed against the pressing force of the two-metal rod 217, that is, the biasing force of the coil spring 20,
The halter can be stably held in the above-mentioned detection state.

The same is true when the button or key chain 2 is inserted upside down.

The above is an explanation of an example of a single key chain storage case 5. If the central management system for each room mentioned at the beginning is adopted, a large number of such storage cases 5 would be required as a unit even in the past. However, the preferred method for arranging them is to arrange them in multiple stages on the panel surface.

Therefore, in the case of the present invention, as a means for arranging the storage case units in parallel with the panel, T-shaped barriers 22, which are well-known connectors, are attached to both sides of the storage coove 5 near the opening, and a large number of storage cases are arranged in a parallel direction. The storage case 5 is made so that it can be connected to each other, and the left wide portion 22a (upper and lower protrusions) of the barrier 22 and the plate springs 22b that are attached opposite to the stepped portions of both protrusions 22a. The entire body is inserted into the communication port 23 of the panel P (Figs. 3 and 4).

That is, the panel P is designed to arrange a large number of storage case units in parallel in multiple stages, and the communication port 23 is a so-called elongated hole of a constant width formed in the horizontal direction of the panel P.
The upper and lower edges of this communication port 23 are sandwiched between the projecting piece 22a of the barrier 22 and the bent portion of the free end of the leaf spring 22b.

Therefore, a large number of connected storage cases 5 are arranged in parallel along the communication port 23.

By the way, the means to attach the barrier to the storage case 5 is by using the side plates 6.
Fix the L-shaped thin plate metal fittings 24 at the predetermined positions of a * 6b, and attach the outward protruding pieces of each metal fitting to the barrier 22.
22c and 22. d, so the fixing position of the metal fittings 24 of the storage case 5 to be connected is Slin) 22
c and 22d are alternately shifted.

As mentioned above, the storage case of this invention has a clever structure that allows reliable detection to be obtained simply by inserting the key chain, and this state is maintained, so there are almost no drawbacks like the conventional ones, and it is suitable for this type of key management system. You can expect excellent results.

Further, since the storage cases are made into units that can be connected to each other, it is easy to increase or decrease the number of key chains or to perform maintenance.

Furthermore, the practical benefits are significant, such as the appearance of the panel surface on which the storage case is arranged.

Note that the above-mentioned detection means may be of a magnetic type or a photoelectric conversion type other than those illustrated, and in short, the present invention can be implemented in various ways within the scope of its gist.
