Description

[Detailed description of the invention] The invention is used as an accessory to a telephone. This invention relates to a mounting structure for a telephone number card case (hereinafter referred to as a card case) used to insert a telephone number card.

Conventionally, in this type of card case mounting structure, in order to provide a card case receiving groove on the side wall of the bottom plate on the back of the phone, a plurality of grooves (generally two) are installed on the outside of the side wall of the bottom plate.
) It is common to be equipped with a protrusion that is approximately L-shaped in cross section.

However, as mentioned above, this card case mounting structure is not desirable from the aesthetic point of view of the phone design because it is provided with a protrusion for receiving the groove on the outside of the phone case, and furthermore, the card case mounting angle is not fixed. Generally, the surface of card cases made of transparent synthetic resin plates generates reflected light from lighting, which often makes it difficult to read the characters written on the cards inside. .

The present invention eliminates the above-mentioned drawbacks, maintains the original beauty of the phone case, and provides a practically convenient structure because the mounting angle of the card case can be changed.

A detailed explanation will be given below with reference to the drawings. FIG. 1 is a side view of a card case attached to a telephone according to an embodiment of the present invention. 1 is a lower casing, 2 is an upper casing, and 3 is a gap formed at the joint between the upper casing 2 and the lower casing 1. (The inside of the phone is covered so that the inside of the phone is not visible) 4 is a card case which has a telephone number card insertion part 5 on the back side and an overhang part 8 (see Figure 2) in the center of the lower end of the card case 4. The projecting portion 8 is inserted and locked into the gap hole 13 (see FIG. 3) of the gap 3 described above, and the auxiliary pieces 12 provided at both lower ends of the card case 4
This figure shows a state in which the card case 4 is supported at a practical inclination angle by pressing the outer wall of the lower casing 1 with the members a and 12b (see FIG. 2).

FIG. 2 shows the shape of the card case 4, in which the protruding root portion 6 at the center of the lower end is bent upward in the figure at a first bent portion 7, and a narrower protruding portion 8 protrudes, and the tip 10 of the protruding portion is a second bending portion 7. Bent part 11
It is bent upward as shown. On the other hand, engagement holes 9a, 9b, and 9c are provided in the center of the overhanging portion 8, which are bored in parallel in the direction of insertion into the gap hole 13, and auxiliary pieces 12a are provided in both lower end pieces of the card case 4. , 12b are provided in a protruding manner.

FIG. 3 is a partially enlarged sectional view of the card case 4 inserted into and engaged with the gap hole 13 described above. First, the card case mounting structure will be explained with reference to FIG. 3a.

The protruding portion 8 of the card case 4 is inserted in the direction of arrow A through the gap hole 13 provided at the joint between the upper and lower casings, and the protrusion 15 provided on the outer peripheral rib 14 of the upper casing 2 (see Fig. 4b) For example, as shown in the figure, the card case 4 becomes depressed and engaged with the engagement hole 9c, and at the same time tries to fall down in the direction of arrow B, but the auxiliary pieces 12a and 12b (see FIG. 2) By pressing, it is raised in the direction of arrow C, and the projecting portion 8 also acts to press the outer circumferential rib 14 in the direction of arrow D, so that a more stable mounting structure can be obtained. Next, a method of adjusting the inclination angle of the card case 4 will be explained with reference to FIG.

First, as shown in FIG. A state maintained at α1 shown in the figure is shown. In Fig. b, the protruding portion 8 is pulled out from the gap hole 13 in the direction opposite to the direction of arrow A from the state shown in Fig. A, and as shown in the drawing, since the engagement hole 9a is engaged with the protrusion 15, the card case 4 is held rotated in the direction of arrow B, and the inclination angle is changed to α2.

Note that it is clear that the above-mentioned adjustment range of the inclination angle can be slightly changed depending on the length of the projecting portion 8 or the number of engagement holes 9. Further, the tip 10 of the overhanging portion of the card case 4 acts to prevent the overhanging portion 8 from being easily removed from the clearance hole 13 when the overhanging portion 8 is pulled out in the opposite direction to the direction of arrow A when adjusting the inclination angle. In order to achieve this, as described above, the second bending portion 11 (see FIG. 2) is bent upward in the drawing in advance.

FIG. 4a is a cutaway perspective view of the lower housing 1, showing the left wall 18 of the edge 16 and the inner circumferential rib 17 provided on the edge 16.
and a recess formed by the right wall 19. On the other hand, FIG. 4b is a perspective view of the broken inner surface of the upper housing 2.
A semi-cylindrical protrusion 15 is formed on the outer peripheral rib 14, and the gap hole 13 shown in FIG. 4a has an edge 16 in FIG.
Left wall 18, right wall 19, and outer peripheral rib 14 in figure b
The protrusion 15 is formed as a horizontally elongated hole surrounded by the gap hole 13, and the protrusion 15 is provided to protrude from the center of the gap hole 13.

Here, an example of imparting elasticity to the aforementioned protrusion 15 will be explained with reference to FIG. Notches 21a and 21b are provided in the outer wall of the upper housing 2, including the outer peripheral rib 14.
If a protruding piece 20 is formed with the above-mentioned protrusion 15 provided on both ends, and the aforementioned protrusion 15 is provided on the head of the protruding piece 20, since the protruding piece 20 is made of a synthetic resin molded product, the direction of insertion and removal of the protruding portion 8 of the card case 4 will be Since it has elasticity, the effect of smoothing the insertion and removal operation of the projecting portion 8 can also be obtained.

In place of the engaging holes 9a, 9b, 9c provided in the overhanging portion 8 of the card case 4 shown in FIG. 2, FIG. This shows an embodiment in which the projection 15 is individually provided and is engaged with the projection 15 described above.

As is clear from the above description, according to the present invention, the card case can be easily attached and detached, and the attachment angle of the card case can be changed, so it is extremely convenient in practice. Further, since there is no need to provide a protrusion for attaching a card case as in the conventional case on the outer wall of the phone case, it is aesthetically elegant.
