  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a side view of the portable device 1 according to the present embodiment in a normal time (when the housing is not released). The portable device 1 is, for example, a wireless key that is carried by a user of the vehicle and remotely controls locking and unlocking of the door of the vehicle. That is, the portable device 1 has a push-type button (not shown) that instructs to lock or unlock the door so as to be exposed from the housing 2, and when the user presses the button, A signal for instructing locking or unlocking is wirelessly transmitted.

  The portable device 1 includes a housing 2, and a battery such as a substrate on which various electronic components are mounted and a button battery for supplying power to the electronic components is housed in an internal space 22 (see FIG. 2) of the housing 2. ing. The battery is fixed to, for example, the inner surface of the substrate or the housing 2.

  As shown in FIG. 1, the housing 2 is formed in an oval shape having an elliptical shape in a side view and an elliptical shape in a plan view. Also good. The housing 2 is formed by fitting an upper case 3 and a lower case 4 having the same shape. Specifically, in FIG. 1, the upper half of the housing 2 is the upper case 3 and the lower half is the lower case 4. Each of the cases 3 and 4 is formed in a bowl shape having an elliptical opening. As shown in FIG. 2, a claw portion 11 extending toward the upper case 3 is formed on the inner surface of the lower case 4, and a groove portion 12 that is hooked on the claw portion 11 is formed on the inner surface of the upper case 3. Has been. And when the opening of each case 3 and 4 is faced | matched, the housing | casing 2 is formed by the nail | claw part 11 and the groove part 12 (fitting part) fitting. That is, the upper case 3 and the lower case 4 are coupled to each other by snap fitting by the fitting portions 11 and 12. The fitting portions 11 and 12 are formed over the entire circumference in the circumferential direction of the butting portion 7 (see FIG. 1) of the cases 3 and 4 or at a plurality of locations.

  As shown in FIG. 2, each of the upper case 3 and the lower case 4 includes a rigid body 5 and an elastic body 6 provided so as to cover the entire surface of the rigid body 5 (provided on the appearance design side). It has a layer structure. The rigid body 5 and the elastic body 6 are integrated by insert molding or two-color molding. That is, the cases 3 and 4 are configured as a combined body of the rigid body 5 and the elastic body 6.

  The rigid body 5 is formed of the same material as that for forming a general casing, and specifically, is formed of a resin such as polycarbonate, ABS, or polyamide. The rigid body 5 has such a hardness and thickness that it will not be deformed even if it receives a certain amount of impact so that the parts accommodated in the internal space 22 can be protected even when the portable device 1 receives an impact such as dropping. ing.

  Further, a concave portion 8 (forced portion) for unlocking the fitting of the housing 2 (cases 3 and 4) is formed on the surface of the rigid body 5 at the position of the butting portion 7 of the cases 3 and 4. Yes. In a normal state (in the case of FIG. 1), the concave portion 8 is concealed, but in FIG. 1, the concave portion 8 is indicated by a hidden line. The rigid body 5 of the upper case 3 is formed with an upper concave portion 9 that is recessed upward (upper case 3 side) when viewed from the direction of FIG. Further, the rigid body 5 of the lower case 4 is formed with a lower concave portion 10 that is recessed downward (lower case 4 side) when viewed from the direction of FIG. The upper concave portion 9 and the lower concave portion 10 are combined to form a rectangular concave portion 8 when viewed from the direction of FIG.

  In addition, as shown in FIG. 2, the recess 8 is formed in a bottomed shape having a certain depth in the thickness direction of the rigid body 5, but may be formed in a shape penetrating to the internal space 22. The concave portion 8 has a size such that a plate-like object such as a coin or a flat-blade screwdriver can be inserted. Furthermore, the recessed part 8 is formed in the position of the non-joining parts 13 and 14 mentioned later.

  The elastic body 6 is formed of an elastic material such as silicon, elastomer, EPDM, or butyl rubber that undergoes elastic deformation when a force is applied and returns to the original state when the force is released. The hardness and thickness of the elastic body 6 are adjusted so that unbonded elastic portions 15 and 18 described later can be bent by a user's force (without using a special instrument). The surface of the elastic body 6 constitutes the appearance design of the portable device 1.

  The cases 3 and 4 are combined bodies of the rigid body 5 and the elastic body 6 but have unbonded portions 13 and 14 (see FIG. 2) where the rigid body 5 and the elastic body 6 are not partially coupled. The non-bonding portion 13 of the upper case 3 is provided so as to surround the upper recess 9 (including the upper recess 9) at the position where the upper recess 9 is formed. Similarly, the non-bonding portion 14 of the lower case 4 is provided so as to surround the lower recess 10 (including the lower recess 10) at the position where the lower recess 10 is formed. In FIG. 1, the range surrounded by the dotted line A and the butting portion 7 indicates the range of the upper non-coupling portion 13, and the range surrounded by the dotted line B and the butting portion 7 is the range of the lower non-coupling portion 14. Is shown. These non-bonding parts 13 and 14 are formed symmetrically with respect to the line of the butting part 7 when viewed from the direction of FIG. Thus, the recessed part 8 (the upper recessed part 9 and the lower recessed part 10) is formed in the position of the non-bonding parts 13 and 14.

  Further, the upper non-bonding portion 13 is formed at a position including a part of the peripheral edge portion (butting portion 7) of the upper case 3. Therefore, the non-bonded elastic part 15 located in the non-bonded part 13 of the elastic body 6 has a non-constrained edge 17 that is not constrained by the combined elastic part 16 coupled to the rigid body 5 of the elastic body 6 ( (See FIG. 2). Similarly, the lower non-bonding portion 14 is formed at a position including a part of the peripheral edge portion (butting portion 7) of the lower case 4. Therefore, the non-bonded elastic part 18 located in the non-bonded part 14 of the elastic body 6 has a non-constrained edge 20 that is not constrained by the combined elastic part 19 of the elastic body 6 that is bonded to the rigid body 5 ( (See FIG. 2). As shown in FIG. 2, the non-restraining edge portions 17 and 20 are aligned at the same position in a normal state.

  As described above, the non-bonded elastic portions 15 and 18 are not coupled to the rigid body 5 and have the unconstrained edge portions 17 and 20, so that when a force is applied to the surface of the rigid body 5. It is possible to bend (flexible deformation is possible) until the formed recess 8 is exposed (see FIGS. 3 and 4).

  As shown in FIGS. 1 and 2, in a normal state, the recess 8 is concealed by the elastic body 6 (non-bonded elastic portions 15 and 18) that is a component of the cases 3 and 4. That is, the concave portion 8 can be concealed without providing any parts separately from the cases 3 and 4. Thereby, the recessed part 8 cannot be visually observed from a user, and the design property of the portable device 1 is not impaired (a design property can be ensured). Moreover, since the recessed part 8 can be installed in any place in the vicinity of the boundary (butting part 7) between the cases 3 and 4, the degree of freedom of design (design) increases.

  On the other hand, with conventional mechanical key-attached portable devices, in order to ensure design, a concave part (forced part) is provided near the mechanical key and the concave part is hidden by the mechanical key. There were restrictions on the location. According to the present invention, the concave portion can be concealed even in a portable device without a mechanical key.

  As shown in FIGS. 3 and 4, when replacing the battery, the user applies a force to the non-bonded elastic portions 15 and 18, and the upper non-bonded elastic portion 15 is bent upward in FIGS. 3 and 4. The lower unbonded elastic portion 18 is bent downward in FIGS. 3 and 4, that is, the unbonded elastic portions 15 and 18 are bent in opposite directions to expose the entire recess 8. Can do. In this state, the fitting of the casing 2 (fitting of the fitting portions 11 and 12) can be released by inserting and twisting a plate-like object such as a coin or a flat-blade screwdriver into the recess 8. When the force applied to the non-bonded elastic portions 15 and 18 is released from the state shown in FIGS. 3 and 4, the state returns to the state shown in FIGS.

  As described above, according to the present embodiment, since the force application portion (concave portion) is provided in the non-joining portion of the case, the force application portion can be concealed at normal times without increasing the number of parts. This ensures design. In addition, since the entire surface of the rigid body is covered with an elastic body, it is possible to reduce an impact such as a drop of the portable device, and it is possible to prevent the portable device from being damaged and the housing from being fitted open.

  In addition, both the upper case and the lower case are configured as a combination of a rigid body and an elastic body, and both are provided with a non-bonded portion. Therefore, when the non-bonded elastic portion is bent (case release) The exposure range of the rigid body surface can be increased and the force applied portion can be easily exposed.

  In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from description of a claim. For example, in the above embodiment, both the upper case and the lower case are provided with recesses for releasing the engagement (upper concave portion, lower concave portion). However, as shown in FIGS. You may provide a recessed part in one side of a case. In the example of FIGS. 5 and 6, the recess 21 is provided only in the lower case 4. The concave portion 21 is formed in a quadrangular shape when viewed from the direction of FIG. 5, and the upper side of the quadrangle is constituted by the peripheral portion of the upper case 3, and the remaining three sides are constituted by the lower case 4.

  5 and 6, the non-bonding portion 13 of the upper case 3 may be eliminated, and the entire upper case 3 may be configured by a combination of a rigid body and an elastic body. Also by this, since the recess 21 is provided in the lower case 3, the entire recess 21 can be exposed by bending the lower unbonded elastic portion 18. 5 and 6, the elastic body of the upper case 3 may be eliminated, and the upper case 3 may be configured with only a rigid body.

  In the above embodiment, an example in which the entire surface of the rigid body is covered with the elastic body has been described. However, only a part around the force applying portion is a combined body of the rigid body and the elastic body, and the other parts are configured only with the rigid body. May be. Moreover, although the said embodiment demonstrated the example which formed the housing | casing with two cases, an upper case and a lower case, you may form a housing | casing by fitting three or more cases. In the above embodiment, the example in which the present invention is applied to the wireless key (portable device) for remotely controlling the locking / unlocking of the vehicle door has been described. However, the portable device responds to the request signal from the vehicle. This signal is transmitted to the portable device other than the wireless key, such as a smart entry system portable device (smart key) that sends a signal and the vehicle side locks and unlocks the door or allows the engine to start based on the response signal. The invention may be applied.

  Moreover, in the said embodiment, although the example which used the recessed part as the force application part was demonstrated, as long as the fitting of a housing | casing can be unlocked by applying force, any force application part may be in any form. good. Moreover, although the example which provided the applied part in the position of the butt | matching part of an upper case and a lower case was demonstrated, you may provide in positions other than a butt | matching part. In this case, for example, an extended contact portion extending to a position other than the abutting portion is provided from one side to the other side of the upper case and the lower case, and the distal end portion is used as the force application portion. The fitting may be unlocked by applying a force to the base side of the extended contact portion.
