Abstract

PROBLEM TO BE SOLVED: To prevent the parts contained in the main body of a portable telephone set and the casing of the telephone set from being affected by the impacts caused by dropping or the like, of the main body and also to prevent the faulty operations or failures of the telephone set due to its breakage or impacts by adding an absorbing member to the casing to absorb the impacts which affect the telephone set. SOLUTION: A weight 8 is attached on the inner side face of the bottom part 1a of a mainbody 1 to set the position of centroid of the body 1 toward the part 1a. An impact absorbing member 7 is prepared on the circumference surface of the part 1a. The other circumference surface of the member 7 is continuous to that of the body 1, so that no undesired projection exist and the external appearance of the body 1 is never impaired. The member 7 has a small reaction coefficient against the floor surface or the like and therefore no rebounding impact is virtually caused. Furthermore, the member 7 has large internal friction and accordingly the impacts are not substantially transmitted to the body 1 or its inside. Then the member 7 uses an elastomer of synthetic rubber or the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A portable telephone according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing a mobile phone according to an embodiment of the present invention. FIG.
FIG. 2 is a front view of a main part of the mobile phone shown in FIG.
FIG. 3 is a side view of the mobile phone of FIG.

As shown in FIG. 1, a speaker 2 serving as a receiving section is provided on the front side of the main body 1 of the portable telephone at the upper end side in FIG. (Hereinafter, referred to as a bottom side) is provided with a microphone 32 which is a transmitting section. Below the speaker 2, an LCD (liquid crystal) display unit 4 for displaying characters and the like is provided. LCD
An operation unit 5 on which operation keys such as numeric keys are arranged is provided between the display unit 4 and the microphone 32. Also, the main body 1
Antenna 6 for transmitting and receiving radio waves related to telephone calls, etc.
Is provided. Also, as shown in FIG. 3, a battery pack 9 is provided on the back of the main body.

FIG. 2 shows a partial cross-sectional view of the bottom of the main body 1. A weight 8 is attached to the inner side surface of the bottom 1a of the main body 1, and the weight 8 causes the center of gravity of the main body 1 to be positioned near the bottom 1a. Also, the main body 1
The shock absorbing member 7 is provided on the bottom peripheral surface of the bottom 1a. The outer peripheral surface of the shock absorbing member 7 and the outer peripheral surface of the main body 1 are continuous, so that unnecessary projections are eliminated and the appearance is not impaired.

As the shock absorbing member 7, a member having a small coefficient of restitution with a floor or the like is used. Thus, the main body 1 that has once fallen on the floor or the like hardly rebounds. Therefore, there is almost no impact due to the rebound of the main body 1. Further, as the shock absorbing member 7, a member having a large internal friction is used. Accordingly, the impact between the main body 1 and the floor surface or the like at the time of the fall is reliably attenuated by the shock absorbing member 7, and the impact is hardly transmitted to the main body 1 or the inside thereof. For example, a synthetic rubber elastomer is used as the shock absorbing member 7.

Next, the operation of the main body 1 configured as described above will be described. For example, if the body 1 has fallen from the top of the main body 1 to the floor, the weight 8
As a result, the posture changes from the bottom of the main body 1 toward the floor. Then, the shock absorbing member 7 provided at the bottom of the main body 1 collides with the floor surface. The impact between the main body 1 and the floor surface or the like at that time is attenuated by the impact absorbing member 7. Therefore, the impact is hardly transmitted to the housing 1a or the electronic components in the main body 1. In addition, the impact absorbing member 7 suppresses the rebound of the main body 1 once dropped on the floor surface or the like, and almost no impact due to the rebound is caused.

In the above embodiment, the case where the shock absorbing member is provided on the bottom is described. However, the shock absorbing member may be provided on the entire circumference of the main body. At this time, it is possible to improve the holdability such as a hand grip, and also to achieve excellent waterproofness.

Further, in the above embodiment, the case where the shock absorbing member is provided on the bottom portion has been described, but it goes without saying that the shock absorbing member is provided on the back surface if the center of gravity is near the back surface.

Further, in the above-described embodiment, the case where the telephone is a telephone that talks with the base station has been described. However, the present invention can be applied to a telephone that is carried indoors such as a PHS or a handset of a parent-child telephone. The same can be applied.

[0014]

As described above, according to the first aspect of the present invention,
Even when the main body is accidentally dropped on the floor or the like, the impact between the main body and the floor or the like is reliably absorbed by the shock absorbing member. For this reason, it is possible to prevent a problem that the housing is damaged and a problem that the internal electronic components and the like are subjected to an impact to cause a malfunction and a failure. In addition, when the shock absorbing member is provided on the entire circumference of the main body, it is possible to improve the holdability such as a hand grip and to have excellent waterproofness.

According to the second aspect of the present invention, when the main body falls, it always falls from the shock absorbing member side. Therefore, the shock absorbing member always collides with the floor or the like, breaking the antenna,
Problems such as breaking the CD display section or disabling the key are prevented. Furthermore, since it is not provided on the entire circumference of the main body, a small amount of the shock absorbing member can reliably absorb the shock.

According to the third aspect of the present invention, components for attaching the shock absorbing member to the housing, members such as an adhesive and a double-sided tape are not required, and the number of components does not need to be increased. Thereby, the assembling property and productivity are not impaired.
