〔Example〕

An embodiment of the present invention will be described below in detail based on the drawings.As shown in FIGS. 1 to 3, a bracket 1, a guide 2, and a stopper plate 3 are shown.
, an insertion rod 4 for holding the card, and springs 5 and 6.
It is composed of a few structural members.

At least one of the springs 5 and 6 is of a coil type.

The above-mentioned bracket 1 has a roughly shaped side surface and a front wall 1a.
The rear wall 1b and the top wall 1c connecting the upper ends of the front and rear walls 1a and 1b are integrally formed by bending a metal plate or the like, and the front wall 1a and the rear wall 1
b has a rectangular (hexagonal in the illustrated example) mounting hole 1d and a circular mounting hole 1e smaller in diameter than the mounting hole 1d on the same axis and passing through the front wall 1a. It is attached to the inner surface of the front side plate 9a of the card case 9 with screws (not shown).

Further, in the rear wall 1b, a mounting hole 1f for a guide rod 8 is penetrated below the mounting hole 1e, and at the front end of the top wall 1c,
An elongated hole 1g extending in the left-right direction and into which the stopper plate 3 is slidably inserted is penetrated above the mounting hole 1d.

Further, the guide 2 is designed to fit the front and rear dimensions of the bracket 1 and the front plate 9a of the card case 9.
The insertion rod 4 has a length approximately equal to the sum of the plate thicknesses, and the front and rear parts are formed into an irregular shape, and the insertion rod 4 is inserted through the insertion hole 2a through its axis. A tapered hole 2b is formed at the inner end so that it can be attached to the bracket 1 and the insertion rod 4 can be inserted smoothly.

That is, the outer shape of the guide 2 is formed such that the front part is a circular part 2c and the rear part is a square part 2d.
It is formed to have a length approximately equal to the distance between the front and rear walls 1a, 1b, and has a rectangular shape that fits into the mounting hole 1d of the front wall 1a, and the rectangular portion 2d
A fitting cylindrical portion 2e coaxially protrudes from the rear end of the rear wall 1b and has a diameter corresponding to the mounting hole 1e of the rear wall 1b.

Further, in the guide 2, a cut groove 2f for fitting the stopper plate is cut in the radial direction in the upper part of the front end side of the square portion 2d so as to communicate with the insertion hole 2a. The square part 2d is fitted into the mounting hole 1d of the front wall 1a, and the fitting cylindrical part 2e at the tip is fitted into the mounting hole 1d of the rear wall 1b.
By fitting the bracket 1 into the bracket 1, the circular part 2c is integrated into the bracket 1 with the circular part 2c protruding forward. It is fitted and supported in a hole 9b formed through it.

The insertion hole 2a is a large-diameter hole portion 2 through which a large-diameter knob portion (described later) of the insertion rod 4 is inserted.
a', and a small-diameter hole 2a'' which is coaxially connected to the rear end and through which a small-diameter rod portion (to be described later) is inserted, and the large-diameter hole 2a' and a small-diameter hole 2a''. A boundary portion of the portion 2a'' is formed by the upper tapered hole 2b.

The stopper plate 3 has a vertical plate portion 3a formed of a metal plate or the like so as to have a substantially L-shaped side surface.
This is integrally curved with a horizontal plate portion 3b at the lower end, and a window hole 3c is provided below the vertical plate portion 3a with a size that allows the polygonal portion 2d of the guide 2 and the guide rod 8 to be inserted therethrough. Thus, the stopper plate 3 has the rectangular portion 2d of the guide 2 and the guide rod 8 inserted into the window hole 3c, and the upper end thereof inserted into the elongated hole 1g of the bracket 1. A spring hook 3d is disposed so as to be able to slide vertically along the inner surface of the front wall 1a of the bracket 1, and is formed by cutting up from the vertical plate portion 3a in a substantially horizontal direction;
The stopper plate 3 is resiliently biased downward by having both ends supported by a spring hook 1h formed by cutting and raising the top wall 1c substantially vertically, and by interposing the spring 5 therebetween. As a result, the upper edge 3e of the window hole 3c fits into the cut groove 2f of the guide 2, thereby locking into the stopper plate locking groove 4d of the insertion rod 4, which will be described later. A locking mechanism is formed to prevent slippage.

Here, as clearly shown in FIG. 3, the upper edge 3e of the window hole 3c is preferably curved upward in an arc shape so that it can be reliably engaged with the groove 4d.

The insertion rod 4 has a small-diameter rod portion 4a for holding a large number of cards (not shown) by inserting them into holding holes drilled at predetermined positions, respectively, and the rod portion 4a. The guide 2 is integrally formed with a large-diameter knob 4b coaxially formed at the base end of the guide 2. A tapered portion 4c is provided for easy insertion into the insertion hole 2a, and an annular groove 4d for locking the stopper plate is provided on the front outer periphery of the tapered portion 4c.

In this way, the insertion rod 4 is inserted through the insertion hole 2a of the guide 2 and inserted up to the rear end of the card case 9, and the insertion rod 4 is inserted into the guide 2 with the spring 6 mounted on the rod portion 4a. The spring 6 is inserted into the insertion hole 2a of the guide 2, and both ends thereof are inserted into the taper hole 2b.
The insertion rod 4 is elastically biased in the withdrawal direction by being supported by the taper portion 4c of the knob portion 4b, and the insertion rod 4a is pressed and inserted to a predetermined position against this spring force. , the window hole 3 in the stopper plate 3 is placed in the groove 4d.
The upper edge 3e of c is locked, whereby the insertion rod 4a is held in a suspended state in the card case 9, and in this holding state, the stopper plate 3 is held against the elastic force of the spring 5. If the rod is then pushed up as shown in FIG. 2, it will be unlocked from the groove 4d, and the insertion rod 4 will be pushed forward from the guide 2 by the elastic force of the spring 6. It is configured such that the extraction operation can be performed by holding the portion 4b.

At the lower end of the front plate 9a of the card case 9, there is a notch 9c so that the lower end horizontal plate part 3b of the stopper plate 3 can be inserted into the lower end.
is formed, and a finger hook part 9d is formed in the front position thereof.
is provided.

If it is necessary to cover the device with a cover 10, the cover 10 has a width that matches the inner dimension in the width direction of the card case 9, and the cover 10 is bent into a substantially half-crank shape on the side, and the upper end of the cover 10 is secured with a screw. 11... It is preferable to arrange the brackets 1 in a stacked manner inside the bracket 1 by fixing them to the inner surface of the front side plate 9a with a stopper. In this case, the cover 10 also has the insertion rods 4 and It goes without saying that the insertion holes 10a and 10b for the guide rod 8 are formed respectively.

The guide rod 8 has its front end inserted through the insertion holes 10b, 1f and the window hole 3c and fitted into the blind hole 9e of the front plate 9a, and its rear end inserted into the rear plate 9f of the card case 9. By being fixed with screws 12, it is installed below and parallel to the insertion rod 4.

In FIG. 1, reference numerals 13 and 14 indicate a clip and a card holder, respectively, which are inserted through the guide rod 8 with a spring 15 interposed therebetween so as to be able to slide in the front-rear direction and hold it in any desired position. As is known, the rod portion 4a of the insertion rod 4 is inserted into and removed from the clip 13 and the card holder 14.

In the above structure, the insertion rod 4 is pressed and inserted as described above against the elastic force of the spring 6, and is inserted into the groove 4d at the upper edge of the window hole 3c in the stopper plate 3. 3e is locked, so that it is held in the inserted state shown in FIG. 1.

In this state, the stopper plate 3 is inserted into the insertion rod 4 through the cut groove 2f of the guide 2 by the spring 5.
As a result, the insertion rod 4 is held in such a way that it will not come out inadvertently, and a card (not shown) is inserted and held in the rod 4.

Next time you add or remove a card,
From the above state, by pushing up and sliding the stopper plate 3 against the elastic force of the spring 5,
The upper edge 3e of the window hole 3c also moves upward, thereby releasing the insertion rod 4 from the groove 4d.

Therefore, the knob 4b of the insertion rod 4, which is biased by the spring 6 in the withdrawal direction, is pushed outward according to the biasing force of the spring and protrudes outward from the guide 2, so that the knob 4b When the insertion rod 4 is held and pulled out, the insertion rod 4 becomes in the detached state as shown in FIG. 2, and thereby the card can be removed or refilled.

At this time, the spring 6 is taken out integrally with the insertion rod 4 in a state where it is sheathed on the insertion rod 4.

Next, when inserting the inserted rod 4 that has been removed, it is inserted into the insertion hole 2a of the guide 2 from the rod portion 4a side, but since a tapered hole 2b is provided at the inner end of the insertion hole 2a, The tip of the rod portion 4a is guided by the tapered hole 2b into the small diameter hole 2a'' at the tip, so that insertion can be easily performed.

By further inserting the insertion rod 4, the knob 4b is inserted into the insertion hole 2a of the guide 2, but since the end of the knob 4b is a tapered part 4c, When the tapered part 4c is inserted halfway without hitting the edge of the opening, the tapered part 4c hits the upper edge 3e of the window hole 3c of the stopper plate 3, but the insertion rod 4 is strongly pressed. By pushing in, the force acts on the stopper plate 3 as a pushing force on the stopper plate 3 by the tapered surface of the tapered portion 4c, and therefore the stopper plate 3 is pushed up against the spring force, and this As a result, the knob portion 4b is inserted to a predetermined position against the elastic force of the spring 6, and at this time, the stopper plate 3 returns to the lower position and engages with the groove 4d as described above, and the insertion rod is inserted. 4 is held in an inserted state.

Also, when inserting the insertion rod 4, first hold the stopper plate 3 in the pushed up position as described above, and after inserting it to a predetermined position, release the pushing up force and return it to the lower position. Good too.

[Effect of idea]

As described above, the present invention not only functions as a card holding device for a card case, but also provides the following effects when assembling the card holding device.

A guide 2 having an insertion hole 2a passes through the card case front plate 9a, the bracket front wall 1a, the stopper plate 3, and the bracket rear wall 1b, and opens from the card case front plate 9a to the bracket rear wall 1b. From, insert rod 4
Simply insert this into the card case 9 through the insertion hole 2a of the guide 2.
reaches inside the card case 9 without being disturbed on the way.

Since the coil-wound spring 6 is attached to the outer periphery of the rod portion 4a of the insertion rod 4, the spring 6 is attached at the same time as the insertion rod 4 is inserted.
fits into the insertion hole 2a of the guide 2, and
The tapered hole 2b is the rod part 4a of the insertion rod 4
Since only the coiled spring 6 is allowed to pass through and the coiled spring 6 is prevented from passing, the spring 6 naturally fits into the insertion hole 2a at a predetermined position.

Only a few main parts are required, such as the bracket 1, guide 2, stopper plate 3, and insertion rod 4. Based on the guide 2, the external bracket 1, stopper plate 3, and internal insertion rod 4 are Because they are distributed and combined three-dimensionally, the structure is simple and economical.
