Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a casing structure of a communication device used with a handset such as a wall-mounted desk phone.

[0002]

[Prior art]

 As is well known, in communication devices that are sometimes used in so-called portrait orientation (for example, a wall-mounted desk phone), a wall hook that can be hooked in the recess of the handset is provided in the communication device main body. When using the same communication device body, the handset recess may be used by hanging it on the wall hook, but if the wall hanging hook is left horizontal, the wall hook will not fit in the handset recess. You may accidentally get caught and drop your handset.

For this reason, conventionally, the above-mentioned wall-mounted hook is formed separately from the communication device housing, and a mounting groove into which the same wall-mounted hook can be inserted / removed is formed in the communication device housing so as to face the same mounting groove. A structure in which an elastic claw for preventing the falling is provided is proposed in Japanese Utility Model Publication No. 3-9410 (Japanese Utility Model Publication No. 61-57736). In other words, in the case structure of this communication device, by changing the wall-hanging hook with respect to the communication device body depending on the direction of use of the communication device body, the wall-hanging hook can be used only when the communication device is hung on the wall. To exert the function of.

[0004]

[Problems to be solved by the device]

 However, even with such a replacement wall hook, there is a problem that noise is generated in recent communication devices. That is, in recent communication equipment, a speaker is often built in the communication equipment body and the received sound is amplified by this speaker. Therefore, a slight vibration occurs in the communication equipment housing at the output of the speaker. And a lightweight wall hook that is not sufficiently restrained with respect to the communication device housing vibrates, causing "chattering noise".

The object of the present invention is to take advantage of the structure in which the wall hook can be replaced and used depending on the direction of use in view of the current state of the conventional housing structure of communication equipment as described above. It is to obtain a housing structure of a communication device that does not generate a vibration sound of a wall hanging hook even when vibration is applied to the communication device housing.

[0006]

[Means for Solving the Problems]

 In order to achieve this object, the present invention forms a mounting groove formed facing a recess for a receiver formed on a panel surface of a communication device housing, and has a hook piece hooked in a recess of a receiver of a handset. In a housing structure of a communication device in which a detachable wall hook is inserted / locked in the mounting groove, a pair of finger hooks having the hook piece on one side are formed on both sides, and a connecting portion of the wall hook is formed on the mounting groove. An elastic claw is integrally formed on one of the pair of guide walls of the communication device housing that is slidably positioned and forms the mounting groove, and engages with the locking groove on the side surface of the connecting portion to The two-dimensional protrusion for urging the wall hanging hook in a plane parallel to the panel surface and the thickness direction protrusion for urging the wall hanging hook in the thickness direction by contacting the opposing surface of the wall hanging hook for finger hanging of the elastic claw. Communication equipment formed on the tip It is intended to propose a housing structure

【Example】

 The embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a front view of a desk-top telephone for wall-mounted type according to the present invention. A dial button 2 and various functions are provided on a panel surface 1a of a telephone housing 1 (communication equipment housing) which is a master unit of a cordless telephone. Button 3 is arranged.

On the left side of the panel surface 1a, there are formed a speaker hole 4, and a recess 6 for the receiver and a recess 7 for the receiver for receiving the receiver and transmitter of the handset 5 shown by phantom lines, respectively. It Further, on the surface of the telephone housing 1 facing the dent 6 for the handset, there is formed a mounting groove 9 into which a wall hook 8 shown in detail in FIGS. 2 to 5 can be mounted.

That is, in FIGS. 2 and 4, a pair of guide walls 10L and 10R facing each other in the left-right direction of FIG. 2 are located inside the edging formed on the panel surface 1a. Between 10L and 10R, a mounting groove 9 is formed which extends in the vertical direction in FIG. 2 and is opened inside the recess 6 for the receiver. The groove side surface 10a and the upper surface 10b of the right guide wall 10R are used as positioning reference planes for the wall hooks 8 to be described later, and the tips of the left guide walls 10L and 10R have the tips in the left and right directions in FIG. The base of the elastic claw 11 that can be deformed in a direction perpendicular to is integrally molded.

As shown in FIG. 4, the wall hook 8 that can be inserted and removed along the guide walls 10L and 10R is provided with a pair of finger hooks 8a and 8b having a triangular cross-section on which fingertips can be hooked, and these finger hooks 8a and 8b are provided. Are connected by a connecting portion 8c having a width L ₁ corresponding to the mounting groove 9 and a thickness L ₂ corresponding to the thickness of the guide walls 10L and 10R. Further, a locking groove 12 is formed on the side surface of the connecting portion 8c facing the elastic claw 11, and, as can be understood from FIGS. 2 and 3, the elastic groove is formed on the edge of the locking groove 12. The circular arc-shaped two-dimensional projection 11a at the tip of the claw 11 can be pressed. On the other hand, as understood from FIG. 4, the tip end of the elastic claw 11 has an arcuate thickness direction protrusion 11b protruding toward the side opposite to the panel surface 1a. The wall hooks 8 can be pressed against the facing surfaces 8d of the finger hooks 8a and 8b.

A hook piece 8e that can be inserted into the earpiece recess 5a formed in the handset 5 is integrally formed at the end of the finger hook 8a on one side. Therefore, the telephone housing 1 is used by hanging on the wall. At this time, when the wall-mounted hook 8 is mounted in the mounting groove 9 in the orientation as shown in FIG. 5, the hook piece 8e of the wall-mounted hook 8 prevents the handset 5 from falling off from the telephone housing 1.

Since the illustrated embodiment has the above-described structure, when the telephone housing 1 is used on a desk, the wall hook 8 should be mounted in the mounting groove 9 in the orientation as shown in FIGS. 2 and 4. To be That is, in this state, since the hook piece 8e of the wall-mounted hook 8 is on the opposite side of the handset depression 6, the hook piece 8e is prevented from being caught by the handset 5. To hang the telephone case 1 on a wall, remove the wall hook 8 from the mounting groove 9 and reverse the direction of the wall hook 8 to mount the wall hook 8 on the mounting groove 9 again as shown in FIG. When attached, the hook piece 8e of the wall-mounted hook 8 is projected into the recess 6 for the handset, and the state where the earpiece recess 5a of the handset 5 is hooked on the hook piece 8e is obtained.

In any of the above-described portrait orientation and landscape orientation, the wall-mounted hook 8 is held in a state in which it is in close contact with the telephone casing 1, so that even if the telephone casing 1 vibrates due to a speaker, etc. It is prevented that the wall hook 8 vibrates with respect to the housing 1 and a "chattering noise" is generated. That is, in any usage state, as shown in FIG. 3, the arc-shaped two-dimensional projection 11a is pressed against the end edge of the locking groove 12, so that the wall-hanging hook 8 does not move in the vertical direction of FIG. The pressing forces F ₁ and F ₂ act in the right direction. Therefore, the wall hook 8 is pressed against the groove end surface 9a (shown in FIG. 2) of the mounting groove 9 by the pressing force F _{1 and} against the groove side surface 10a of the right guide wall 10R by the pressing force F ₂ . Further, as shown in FIGS. 4 and 5, since the protrusion 11b in the thickness direction of the elastic claw 11 elastically contacts the facing surface 8d of the finger hooks 8a, 8b, the pressing force F ₃ opposes the finger hooks 8a, 8b. The opposite surface 8d is always pressed against the upper surface 10b of the right guide wall 10R. Eventually, the wall hooks 8 are restrained by the telephone case 1 in all directions within the three-dimensional plane by the action of the elastic claws 11, and the wall hooks 8 are lifted from the telephone case 1 to cause the lift. It is possible to prevent “chattering noise”.
