Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for a telephone number card case (hereinafter referred to as a card case) in which a telephone number card attached to a telephone set is inserted and used.

Conventionally, in this type of card case mounting structure, in order to provide a card case receiving groove on the side wall of the lower case on the back of the phone, a plurality of (generally two) approximately L-shaped cross sections are installed on the outside of the side wall of the lower case. It is common to have a protrusion molded into it.

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

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.

An embodiment of the present invention will be described below with reference to the drawings. Figure 1 shows an example of a desk phone, with the lower casing 1
The gap 3 formed at the joint between the upper housing 2 and the upper housing 2 (however,
The inside of the phone is covered with an invisible structure. )
Using the back of the phone, protrude a gap hole 10 (see Figure 4), and insert the card case 4 into the gap hole 10.
This figure shows a state in which the lower end of the lower end is bent and the lower projecting portion 5 is inserted and mounted. Note that 7 has the same shape as the lower protruding portion 5, which is provided by bending the upper end of the card case 4, and both are configured so that the bending angles of the bent portions are different, making it suitable for both tabletop and wall hanging types. It is designed to be compatible.

FIG. 2 shows an embodiment of a wall-mounted telephone, in which the upper protrusion 7 of the card case 4 is inserted into the above-mentioned clearance hole 10. Incidentally, by inserting and mounting the lower projecting portion 5 into the gap hole 10, the inclination angle of the card case 4 can be changed from the above state. Furthermore, depending on the mounting angle of the telephone with respect to the wall surface, the card case 4 can be mounted upside down in the same manner as described above, so there is an advantage that the selection range of the inclination angle of the card case 4 can be further widened.

FIG. 3 is a front view and a side view showing the shape of the card case 4. FIG. A partially protruding and bent lower extension part 5 is provided at the lower end, and a lower locking hole 6 is provided at the central tip thereof. Further, the upper end is also provided with an upper overhanging part 7 and an upper locking hole 8 similar to those on the lower end, and as mentioned above, the lower overhanging part 5 is mainly used for desk-type telephones, and the upper overhanging part 7 is mainly used for wall-mounted telephones. The respective bending angles are set to suit. Note that 6 is a telephone number card investigation section.

Next, the card case mounting structure will be explained in more detail with reference to the partially enlarged side sectional view of FIG. The lower protruding part 5 of the card case 4 is inserted in the direction of arrow A through the gap hole 10 provided at the joint of the casing, and the tip of the lower protruding part 5 is provided to protrude from the inner wall of the lower casing.
Elastic locking piece 11 having elasticity in the directions of arrows B and C
Since the head 12 of is pushed in the direction of arrow B, the lower projecting portion 5 further advances in the direction of arrow A and stops in the state shown. In this state, the semi-cylindrical protrusion 15 provided on the lower end surface 14 of the fixed locking piece 13 protruding from the inner wall of the upper housing is depressed into the lower locking hole 6 provided in the lower projecting portion 5. Since it is loosely fitted, the lower protruding portion 5 is held between the head 12 of the elastic locking piece 11 and the lower end surface 14, and is resistant to force in the card case removal direction (opposite direction of arrow A). It is a structure that cannot be easily removed. To remove the card case 4, move the lower protrusion 5 along the arrow A.
Just pull it out in the opposite direction. In other words, since the elastic locking piece 11 is a molded product, it has elasticity,
When the lower projecting portion 5 presses the head 12 of the elastic locking piece 11, the locking force in the pullout direction can be dispersed and reduced by utilizing the action of bending in the direction of arrow C, thereby reducing the pullout force. It has the effect of In addition, when inserting in the direction of arrow A, use the elastic locking piece 1.
1 is bent in the direction of arrow B, so it has the same effect as when it is pulled out.

FIG. 5a is a cutaway perspective view of the lower casing 1.
is formed by the aforementioned elastic locking piece 11, the left wall 19 and the right wall 20 of the inner circumferential rib 17 provided in front of the head 12, the edge 18, and the inner peripheral rib 17 extending around the edge 18. It has a recessed part. On the other hand, FIG. 5b is a cutaway inner perspective view of the upper casing 2, and as mentioned above, the upper casing 2 includes a fixed locking piece 13 protruding from the inner wall.
Its lower end surface 14 (the upper end shown is upside down),
It has a semi-cylindrical protrusion 15 and an outer peripheral rib 16 at the edge. The clearance hole 10 shown in FIG. 4 is formed as a horizontally elongated hole surrounded by the edge 18 in FIG. 4A, the left wall 19, the right wall 20, and the outer peripheral rib 16 in FIG. B.

FIG. 6 shows an embodiment related to claim (2) of the utility model registration, in which the inclination angle of the card case 4 can be changed. A stepped slope downward to the right is provided adjacent to the right end in the drawing of the lower end surface 14 of the fixed locking piece 13, and from that surface, the protrusion 15
By further providing a second protrusion 22 having the same shape, when the card case 4 is in the state shown in the figure, the lower protruding portion 5 can be pulled out approximately halfway in the opposite direction to the arrow A direction, and the card case 4 can be moved in the arrow D direction. By tilting it down (the card case is in the 4' position), the lower protruding portion 5 is in the 5' position, the aforementioned second protrusion 22 is loosely fitted into the lower locking hole 6, and the card case 4' is in the 5' position. It is understood that the card case 4' does not easily slide down the stepped slope 21 because the force that tends to cause it to fall in the direction D due to its own weight acts in the direction of the arrow E at the tip of the lower overhang 5'. .

As is clear from the above explanation, according to the present invention, the card case can be easily attached and detached, it can be applied to both tabletop and wall-mounted telephones, and the mounting angle of the card case can also be changed. Therefore, 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, the present invention is aesthetically superior and is therefore preferable.
