In the drawings, the same reference numerals as those in the drawing described in Patent Document 1 denote the same components, and the basic configuration is patented. The conventional case shown in Document 1, that is, the case 2 forming the terminal device body 1 is divided into an upper case 2a as a first case and a lower case 2b as a second case, Are similar to a foldable terminal device having a configuration in which the two are connected to each other so as to be openable and closable via a hinge module 3. The joint surface of the key-side case 2b1 and the back-side case 2b2 in which a large number of keys 5 are arranged in the housing 2b is shifted to the back side from the lower case 2b shown in Patent Document 1, and the key-side case 2b1 On the side of the key side case 2b1 The deletion is provided are so as to form an opening 7.

  Then, as shown in FIGS. 2 (a) to 2 (d), 3 and 4, the hinge 8c is extended from the one end side to the cover body 8a covering the opening 7 so as to have flexibility, A first protrusion 8e1 that protrudes at an acute angle (angle α) with respect to the hinge 8c at the tip of the hinge 8c, and an obtuse angle with respect to the hinge 8c on the opposite side of the first protrusion 8e1 A projecting piece 8e having a second projecting piece 8e2 that projects at an angle (angle β) is provided to constitute the cover member 8, and a first engagement that can lock the first projecting piece 8e1. A locking portion 11e having a locking portion 11e1 and a second locking portion 11e2 capable of locking the second protruding piece portion 8e2 is provided at the entrance portion on the opening 7 side of the hinge storage gap portion 9. is there.

  2A to 2D, the cover body 8a of the cover member 8 is provided with claw portions 8d at a plurality of required positions on the outer periphery thereof, and the corresponding in the opening 7 of the terminal device body 1. The claw portion 8d can be engaged and disengaged with respect to an engaging portion (not shown) provided at a location.

  The cover member 8 is made of a hard resin such as an ABS resin or a PC resin as the cover body 8a, and the hinge portion 8c, the projecting piece portion 8e, and the claw portion 8d are elastic and have excellent flexibility. These two different kinds of resin materials can be formed by resin molding, and here, the hinge portion 8c of the cover member 8 is simply extended straight from the cover body 8a. Instead, the protrusion 8e extends in a direction substantially perpendicular to the cover body 8a so as to warp the surface side of the cover body 8a. The line is set as a line L-L shown in FIG. 3 so that the base portion of the first projecting piece 8e1 protruding at an acute angle with respect to the hinge 8c can be molded without being undercut. The Further, by forming the hinge portion 8c to warp the surface side of the cover body 8a, when the cover member 8 is fitted to the key side case 2b1, the hinge portion 8c and the protruding piece portion 8e are It is positioned on the outer peripheral side inside the key side case 2b1, so that the storage space of the hinge portion 8c can be made compact.

  On the other hand, the first locking portion 11e1 is formed at an acute angle (angle γ) so as to be inclined with respect to the hinge portion 8c inserted in the direction of the one-dot chain line in FIG. The acute inclination angle (angle α) of the projecting piece 8e1 and the acute inclination angle (angle γ) of the first locking portion 11e1 with respect to the hinge portion 8c are substantially the same.

  Further, as shown in FIG. 4, the projecting piece 8e is formed such that the width t in the thickness direction of the hinge 8c is longer than the minimum clearance c of the hinge storage gap 9, so that the hinge When the hinge 8c is inserted into the storage gap 9, the acute angle of inclination of the first protrusion 8e1 with respect to the hinge 8c is reduced and the obtuse angle of the second protrusion 8e2 with respect to the hinge 8c. The angle is configured to be large.

  Further, as shown in FIGS. 3 and 4, a relief portion 8f having a reduced thickness is formed at the position of the hinge portion 8c where the first projecting piece portion 8e1 is opposed to the hinge housing gap portion 9. When inserting the protruding piece 8e and the hinge 8c, the first protruding piece 8e1 is easily bent and the first protruding piece 8e1 is inserted into the escape portion 8f so that the protruding portion in the thickness direction of the hinge 8c. The width of the piece 8e can be reduced.

  Further, as shown in FIG. 3 and FIG. 4, in order to facilitate the insertion of the protruding piece portion 8 e and the hinge portion 8 c, a concave portion that is smoothly recessed is formed on the opening portion 7 side of the first locking portion 11 e 1. 12 is provided.

  Incidentally, the cross-sectional shape of the entrance portion having the minimum gap interval c of the hinge storage gap portion 9 is a U-shape opened to the back side as shown in FIG. At the time of insertion into the gap portion 9, the U-shaped portion is elastically deformed in the width direction of the lower housing 2b (left and right direction in FIG. 5), the minimum gap interval c is widened, and the protruding piece portion 8e is inserted. It is designed to be easy. Further, the rear case 2b2 is provided with a protrusion 13 that protrudes toward the hinge storage gap 9 when joined to the key case 2b1, and the hinge 8c is connected to the hinge storage gap 9. When positioned, movement in the thickness direction (upward direction in FIG. 5) is restricted by the protrusion 13.

  Next, the operation of the illustrated example will be described.

  In the terminal device manufacturing process, after various inspections are performed using the interface connector, the cover member 8 is attached to the opening 7 formed in the lower housing 2b of the terminal device body 1 in the final process. In this case, a hinge portion 8c formed with a protruding piece portion 8e having a first protruding piece portion 8e1 and a second protruding piece portion 8e2 is inserted into the hinge storage gap portion 9, and the first protruding piece portion 8e1 and the second protruding piece portion 8e1 The tip shape of the hinge portion 8c formed with the protruding piece portion 8e having the two protruding piece portions 8e2 is a shape in which the T-shape is inclined in an I-shape, and thus is easily deformed in the insertion direction. .

  In addition, when the hinge 8c formed with the protruding piece 8e is inserted into the hinge housing gap 9, the acute inclination angle of the first protruding piece 8e1 with respect to the hinge 8c is reduced, and the hinge The projecting piece 8e bends so that the obtuse inclination angle of the second projecting piece 8e2 with respect to the portion 8c is increased, and the first projecting piece 8e1 bends and enters the escape portion 8f, so that the thickness of the hinge 8c is increased. The width t of the projecting piece 8e in the vertical direction can be reduced, and in addition to this, the opening 7 side of the first locking portion 11e1 has a shape that is smoothly recessed as shown in FIGS. Further, as shown in FIG. 5, the concave portion 12 is provided, and the entrance portion having the minimum gap interval c of the hinge storage gap portion 9 having a U-shaped cross section opened to the back side is elastic in the direction in which the inlet portion is widened. Because it deforms, Even hinge 8c width in the thickness direction t of the part 8e are longer than the minimum gap spacing c of the hinge housing gap portion 9, it is easy to insert the hinge portion 8c in the hinge housing gap portion 9.

  And after inserting the hinge part 8c in which the said protruding piece part 8e was formed in the hinge accommodation clearance part 9, the 1st protruding piece part 8e1 and the 2nd protruding piece part 8e2 return to the original form, but here Since the hinge portion 8c is shaped to warp the surface of the cover body 8a, when the cover member 8 is fitted to the key side case 2b1, the hinge portion 8c and the protruding piece portion 8e are It is located on the outer peripheral side inside the key side case 2b1, and it is not necessary to expand the storage space of the hinge portion 8c, and it is possible to make it compact.

  On the other hand, while the cover body 8a is slid in the direction in which the hinge portion 8c is pulled out along the hinge housing gap 9 to the opening 7 side, the cover body 8a is bent so as to bend the hinge portion 8c. When the opening 7 is opened by being separated from the lower housing 2b of the main body 1, the first projecting piece 8e1 and the second projecting piece 8e2 are first locked as shown in FIG. It is latched by the portion 11e1 and the second latching portion 11e2.

  From this state, when the cover member 8 is pulled in the pulling direction, the first projecting piece 8e1 is in pressure contact with the first locking portion 11e1, and receives a counterclockwise reaction force in FIG. A force in the counterclockwise direction in FIG. 4 also acts on the second protrusion piece 8e2, and the second protrusion piece 8e2 is pressed against the second locking portion 11e2.

  As a result, even if the cover member 8 is pulled in the pulling direction, the first protruding piece 8e1 and the second protruding piece 8e2 bite into the first locking portion 11e1 and the second locking portion 11e2, respectively. The cover member 8 is strongly hooked in a direction that prevents the cover member 8 from being pulled out, and cannot easily be removed.

  In this way, the hinge portion 8c can be easily inserted into the hinge storage gap portion 9 and can be made difficult to be pulled out without being affected by design restrictions, the position of the opening portion 7, and the like.

  It should be noted that the cover structure of the terminal device and the terminal device of the present invention are not limited to the illustrated examples described above, and it is needless to say that various modifications can be made without departing from the gist of the present invention.

  For example, the first locking portion 11e1 that locks the first protruding piece portion 8e1 is formed to be inclined at an acute angle with respect to the hinge portion 8c, and has an acute angle with respect to the hinge portion 8c of the first protruding piece portion 8e1. Although it is configured to have an acute inclination angle (angle γ) that is substantially the same as the inclination angle (angle α), the first locking portion 11e1 is not limited to this configuration. Any configuration may be used as long as the first projecting piece 8e1 is locked when the hinge 8c is slid in the direction of being pulled out toward the opening 7 along the hinge housing gap 9 and pulled in the direction of extraction. Moreover, the 2nd latching | locking part 11e2 should just be the structure which latches the 2nd protrusion piece part 8e2 when it pulls in the direction which pulls out the cover member 8. FIG. Furthermore, for example, the second locking portion 11e2 may be shaped along the hinge portion 8c and the second protruding piece portion 8e2.

  In addition, when the cover member 8 is pulled in the pulling direction, the first protruding piece 8e1 and the second protruding piece 8e2 are simultaneously locked to the first locking portion 11e1 and the second locking portion 11e2. However, before the second protruding piece 8e2 is locked to the second locking portion 11e2, the first protruding piece 8e1 is first locked to the first locking portion 11e1, and the first protruding piece 8e1. After the cover member 8 is further pulled out from the state of being pressed against the first locking portion 11e1 and a counterclockwise force is applied to the second protruding piece portion 8e2, the second protruding piece portion 8e2 is locked into the second locking portion. You may comprise so that it may press-contact to the part 11e2.
