[Industrial application field]

The present invention relates to a mounting structure for mounting a display piece on a surface of a synthetic resin molded product that is inclined with respect to the mold drawing direction.

The housing of the synthetic resin molded product incorporates an electronic / communication device inside for the purpose of external appearance and protection.
Functions for various displays are provided. The display is a luminous body or a character display. In particular, the display of characters and the like, which does not change the display, is provided on the surface of the housing by printing, integral molding, or engraving, but a removable display is adopted for an object that needs to be changed or changed.

[Conventional technology]

FIG. 6 shows a perspective view of the main part of the housing 1. A rectangular recess 2 is provided on the surface of the housing 1, rectangular holes 3 and 3 are provided at both ends, and a round hole 4 is provided in the middle. Reference numeral 5 is a paper piece which is a display piece, 6 is a display piece retainer, and locking pieces 7, 7 are integrally formed at both ends thereof so as to project from left to right. The display piece retainer 6 is a colorless and transparent synthetic resin molded product.

The necessary items are described in the display piece 5, and one of the locking pieces 7 of the display piece presser 6 is attached to the back surface of the display piece presser 6 and the locking piece 7 is attached to the housing 1.
The display piece retainer 6 is fitted into the recessed portion 2 by making the display piece retainer 6 curved and the other locking piece engages with the other rectangular hole 3 of the above. And the locking pieces 7 at both ends are inserted into the back surface of the housing 1. This state is shown in FIG. 7 of the AA cross section and FIG. 8 of the BB cross section.

The display piece 5 is sandwiched between the bottom surface of the recess 2 and the back surface of the display piece retainer 6, and the display piece retainer 6 is fitted in the recess 2 with almost no gap, and the surfaces thereof are flush with each other. Locking piece 7
Is locked so that it can enter the back surface of the housing 1 and the display pressing member 6 cannot be removed. As is apparent from FIG. 8, the recess 2 and the display piece retainer 6 are correct rectangles. This is a molded product which is a resin mold in all cases, and the molding die is formed as a separation mold perpendicular to the plane.

In order to insert or replace the display piece 5, the display piece retainer 6 must be removed, but it is extremely difficult to remove it from the surface. Therefore, by inserting a rod, a pin, or the like from the back surface into the round hole 4 to bend the display piece 5 so as to push it out, the display piece 5 can be removed by the reverse procedure of the attachment.

[Problems to be solved by the invention]

The above-mentioned prior art has no problem because the molding dies can be combined and separated in the direction orthogonal to the surface, but the handset 11 and 12 in the handset 10 of the telephone in FIG. 9 are convenient for operation. The whole is appropriately curved and inclined with respect to each other.

The display piece 5 provided in the vicinity of the mouthpiece 11 can be attached by using the same structure as shown in FIGS. 6 to 8 described above, but as shown in FIG. Since the surface 13 is inclined with respect to the detaching direction C-C ', in order to mold the concave portion 2, it is necessary to form the mold of this part as a split mold which is combined in the DD' direction. FIG. 10 is a cross section corresponding to FIG. Therefore, when the conventional technique is applied, there is a problem that the molding die becomes complicated and the molding efficiency is not good.

[Means for Solving Problems] An object of the present invention is to solve the problems by applying the above-mentioned conventional technique and to improve the efficiency of moldability by simplifying the molding die.

According to the present invention, a means for this purpose is to provide a concave portion on a surface inclined with respect to the drawing direction of the molding die of the synthetic resin molded product,
It has a structure in which the display piece and the display piece retainer are embedded so that the locking pieces at both ends in the lengthwise direction are inserted and locked into the back surface of the molded product to attach them in a detachable manner. As the height direction of the inclined surface, one side face and side end face of the width direction are aligned with the drawing direction of the molding die, and the cross section is inclined with respect to the surface, and the other side face and side end face are symmetrical with the one side face and side end face. And a small hole is provided at the end of the display retainer in the lengthwise direction.

[Action]

Since the cross section of the display piece retainer is inclined so as to be open with respect to the combination separating direction together with the concave portion, the above-mentioned constituting means can be formed as an integral type instead of as a split type.
Also, since both ends are symmetrical, the display presser does not have left-right directionality and can be mounted in either direction.
Further, since the small hole is provided at the end, it can be easily removed by inserting a pin or the like.

〔Example〕

 Hereinafter, the present invention will be described in detail with reference to the drawings.

1 to 5 show an embodiment of the present invention. In FIG. 2, as an embodiment corresponding to FIGS. 9 and 10, a recess 20 is formed in the inclined surface 13 near the mouthpiece of the handset, and the display piece 3 is formed.
0 is shown in the cross section in a state where the display piece pressing member 40 is separated.

The combination separating direction of resin molds (not shown) is C-
A plane 13 is formed with respect to a plane E which is the direction of C'and is orthogonal to this.
Is inclined. The recess 20 has an inverted trapezoidal shape such that the opening width thereof is maximum on the surface 13 side and narrows on the back surface side. The side end surface 21 of the recess 20 coincides with the direction CC ′. This is orthogonal to the plane E. Then, the center line F of the recess 20 is orthogonal to the face 13 and the other side end face 22 is symmetrical to 21. As shown in the plan view of FIG. 3, through holes 24, 24 penetrating the back surface are formed at both ends of the recess 20 in the longitudinal direction.

The width of the display piece 30 is equal to the width of the bottom surface 23 of the recess 20, and the length is equal to the length of the back surface of the display piece retainer 40 described later.

As shown in FIG. 1, the display piece presser 40 has a concave section 20.
Both side surfaces 41, 42 in the width direction are symmetrical trapezoids and have an inverted trapezoidal shape so as to be fitted exactly in. Both ends in the length direction further incline and extend downward, and the locking pieces 43, 4 project in both left and right directions.
3 is integrally molded and is made of transparent synthetic resin. Four
6 is a small hole. As shown in the side view of FIG. 5, a flat surface portion corresponding to the length of the display piece 30 is secured on the back surface 44, and from the end thereof to the lower surface of the locking piece 43. Slopes 45, 45 are formed.

With the above configuration, necessary items such as a telephone number are written on the display piece 30, the front surface is brought into contact with the back surface 44 of the display piece presser 40, and one of the locking pieces 43 is inserted into the hole 24 of the recess and curved to the other. When the locking piece 43 is inserted into the hole 24 of the other concave portion so as to be engaged therewith, the display piece pressing member 40 is restored to a flat state by the elasticity of itself, and is fitted in the concave portion 20. Since the length l of the surface portion is equal to the length L of the concave portion 20, the upper surface of the concave portion 20 is the same flat surface as the surface 13.

Since the recess 20 and the end surface in the width direction of the display piece presser 40 are both symmetrically inclined, the display piece presser 40 has no left-right directionality and can be mounted in any direction.

When the display piece retainer 40 is to be removed because it is necessary to insert or replace the display piece 30, a pin or the like is inserted into the small hole 46 at the end and a force is applied in the length direction. As the central portion of the display piece presser 40 is bent and deformed so as to be lifted, the slope 45 comes in contact with the step 25 of the through hole 24 and rides up to the outside. Still further, when the deformation is added, the locking piece 43 comes out of the through hole 24, so that it can be pulled out, and the other locking piece 43 can be pulled out and removed.

[Advantages of Advantage] As described above, according to the present invention, the molding die can be a simple mating die without forming a complicated split die, so that the molding efficiency can be improved and the display pressing plate can be pressed. It has a remarkable practical effect such that it can be attached and detached from the surface. The invention is not limited to the telephone set of the embodiment and can be applied to various fields.
