Abstract

<P>PROBLEM TO BE SOLVED: To provide a gripper capable of enhancing operability and dignity in a hollow grip structure. <P>SOLUTION: Since only the forward end of a protrusion 19 abuts against a body frame 16 when a rib 15 gripped by a user bends to abut against the body frame 16, a grip 11 touches the body frame 16 only at the forward end of the protrusion 19 and the contact area decreases as compared with an arrangement 1 where the protrusion 19 does not exist. Consequently, the generation of strange sound unique to elastic resin can be reduced when the forward end of the rib 15 is separated from the body frame 16 by separating a finger 21 from the grip 11. <P>COPYRIGHT: (C)2006,JPO&NCIPI

This makes it possible to soften the feel of the part that hits the finger and improve the hold feeling.

  Also, when the user squeezes firmly and the rib is bent until it hits the main body frame, only the tip of the protrusion hits the main body frame, so the contact area of the main body frame and the gripping part is only the tip of the protrusion compared to when there is no protrusion. Therefore, the contact area is reduced, and it is possible to reduce the occurrence of abnormal noise peculiar to the elastic resin when the finger is separated from the gripping portion and the tip of the rib is separated from the main body frame.

  The invention according to claim 1 of the present invention is a grip device that is disposed in a housing of an electronic device and is gripped by a user. The grip device is made of an elastically deformable material, and is integrated with the grip means. And a protrusion disposed on the back side of the part gripped by the user. When the user grips the apparatus and the gripping part is elastically deformed, the protrusion comes into contact with the housing. Thus, the range of elastic deformation can be widened, so that the feel and operability when gripped can be improved.

  According to a second aspect of the present invention, there is provided a grip device that is disposed in a housing of an electronic device and is gripped by a user. The gripping device is made of an elastically deformable material, and the gripping device is integrated with the gripping device. A protrusion formed and disposed on the back side of the gripping portion by the user. A contact portion provided at a contact portion of the protrusion with the housing and partially contacting the housing; the user grips the apparatus and the grip portion is elastically deformed; In this case, when the contact portion comes into contact with the housing, the contact area with respect to the housing can be reduced, and abnormal noise generated when the contact portion is separated from the housing can be reduced. .
