Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for removably holding a telephone number card in a telephone.

FIG. 1 is a bottom perspective view showing a conventional telephone number card holding structure.

Reference numeral 1 denotes a telephone number card, and locking protrusions 1a are provided on both sides of one end. Reference numeral 2 denotes a telephone bottom plate constituting the bottom of the telephone housing, and 3 denotes a card holding portion, which is a rectangular recess provided on the lower surface (in the figure, the upper surface) of the telephone bottom plate 2. Long guide holes 3a are provided on both sides of the concave portion of the card holding portion 3, into which the locking protrusions 1a engage and slide.

The width of the telephone number card 1 is equal to the width of the card holder 3, but the width including the locking protrusion 1a is larger than the width of the card holder 3, so the telephone number card 1 is inserted into the card holder 3. In this case, as shown in FIG. 2 (A-A cross section), by bending the telephone number card 1 and inserting the locking protrusion 1a into the guide hole 3a, the telephone number card 1 will be inserted into the card holder 3. is maintained.

However, bending the telephone number card 1 is not preferable since it is not only difficult to insert, but also may break.

When in use, most of the telephone number card 1 is hidden under the bottom plate 2 of the telephone, but if you pinch the knob 1b of the telephone number card 1 and pull it out, the locking protrusion 1 will be visible.
It can be pulled out until it hits the stopper 4 and is locked.

In this structure, the bottom plate 3b of the card holder 3 is separated from the phone bottom plate 2 by the guide holes 3a on both sides, and the front part 3
Since it is connected to the telephone bottom plate 2 only at the rear part 3d and the bottom plate 3b, there is a drawback that the strength of the bottom plate 3b is weak.

In addition, since the card holder 3 is a synthetic resin molded product together with the phone bottom plate 2, the flow of molding material during molding cannot pass through the guide hole 3a, but only from the front part 3c and rear part 3d. 3
There is a tendency for the molding material to flow sufficiently into the central portion b during molding.

In order to improve these drawbacks, the present invention provides a connecting part in the center of the card holding part to make it easier to insert the telephone number card, reinforces the bottom plate part, and has a structure that allows the molding material to flow easily during molding. This is what we are trying to do. The drawings will be explained in detail below.

FIG. 3 is a bottom perspective view of a telephone bottom plate showing an embodiment of the present invention.

5 is a telephone number card, 6 is a bottom plate of the phone, and 7 is a card holding portion, which is a substantially rectangular recess provided on the bottom surface of the bottom plate 6 of the phone.

Two guide holes 7a and 7b are provided on both sides of the concave portion of the card holding portion 7 with the connecting portion 8 in between. The bottom plate 7c of the card holder 7 has guide holes 7a, 7 on both the left and right sides.
Although the bottom plate 7c is connected to the phone bottom plate 6 by the connecting portion 8 provided in the center, the bottom plate 7c can have sufficient strength.

Furthermore, the flow of the molding material during molding also flows from the connecting part 8 to the outside of the front part 7d and rear part 7e of the card holding part, so the molding material is injected sufficiently uniformly into the bottom plate 7b of the mold, so that the molding process is completed. It's easy to do.

When inserting the telephone number card 5 into the card holder 7, turn over the telephone bottom plate 6 and insert the telephone number card 5 (C-C
Insert the telephone number card 5 diagonally from the rear of the card holder 7 as shown in the cross section). Since the width of the card holding part 7 is larger than the width including the locking protrusion 5a of the telephone number card 5 at the position of the connecting part 8, the locking protrusion 5a of the telephone number card 5 is placed at the position of the connecting part 8. When inserted, the telephone number card 5 is easily inserted into the card holder 7 as it is, and the locking protrusion 5a is inserted into and engaged with the guide hole 7a or 7b.

When pulling out the phone number card 5 from under the bottom plate 6 of the phone during use, place your fingertips on the knob 5b of the phone number card 5 and pull it out, and the locking protrusion 5a will slide into the guide holes 7b and 7a. When it is pulled out, it hits the stopper 9 at the end of the guide hole 7a and is locked so that it does not fall out.

As explained above, according to the present invention, the telephone number card can be easily inserted into the card holder as it is, and the bottom plate of the card holder can also have sufficient strength. There's no such thing as flopping.

Also, during molding, the structure allows the molding material to easily flow into the bottom plate portion, making it easy to mold.
