JP 2014-187586 A (paragraph [0021], FIG. 2 etc.)

  In Patent Document 1, in order to pull out the ring portion from the concave portion, it is necessary to put a finger between the concave portion and the ring portion.

  The case for a mobile terminal according to the present invention includes a ring movably attached to the case body, a recess that accommodates the ring, and an operation unit that is disposed inside the ring accommodated in the recess and is pushed by the user. Have. A part of the operation unit is connected to the bottom surface of the recess, and the operation unit protrudes from the bottom surface of the recess. Further, a claw portion is provided on the operation portion that applies a force toward the outside of the concave portion to the ring by elastic deformation of the operation portion due to pushing.

  According to the present invention, the ring accommodated in the concave portion can be moved to the outside of the concave portion by pushing the operating portion. Specifically, when the operating portion is pushed in, the ring is pressed against the bottom surface of the recess by the claw portion, so that the ring receives a reaction force from the bottom surface of the recess. When the operation portion is continuously pushed in, the pressing of the ring by the claw portion is released, and the ring moves toward the outside of the concave portion by the reaction force described above. Thereby, since a part of ring can be protruded from a recessed part, the user can pull out a ring easily from a recessed part.

  A nail | claw part can be provided in an operation part on the opposite side to the connection part of an operation part and a bottom face. When the operation part is pushed in, the connection part between the operation part and the bottom surface becomes the base point, and the operation part is elastically deformed.However, by providing a claw part on the opposite side to this base point, the claw part is pushed by pushing the operation part. It becomes easier to secure the amount of movement. By securing the amount of movement of the claw portion, the claw portion can be moved to a position where it does not come into contact with the ring after the pressing of the ring by the claw portion is released. Thereby, when a ring moves toward the outer side of a recessed part, it can prevent that a nail | claw part remains in contact with a ring, and it can suppress that the movement of a ring is prevented.

  A spherical portion can be provided on the ring, and the spherical portion can be slidably attached to the case body. Thereby, a ring can be moved to a predetermined direction centering on a spherical part, or the direction of a ring can be changed freely.

  By bringing the friction material into contact with the spherical portion, frictional resistance can be generated between the spherical portion and the friction material. Thus, after the ring is moved to the outside of the recess by pushing the operating portion, a part of the ring can be left protruding from the recess by the frictional resistance between the spherical portion and the friction material. That is, it is possible to prevent the ring protruding outside the recess from returning to the inside of the recess.

  Hereinafter, a case which is an embodiment of the present invention will be described. The case of this embodiment is used by being attached to a mobile terminal such as a smartphone.

  FIG. 1 is a diagram (front view) showing the front surface of the case, and FIG. 2 is a diagram (rear view) showing the back surface of the case. 3 is a view (left side view) when the case is seen from the direction of the arrow D1 shown in FIGS. 1 and 2, and FIG. 4 is a view when the case is seen from the direction of the arrow D2 shown in FIGS. It is a figure (right view).

  5 is a view (top view) when the case is viewed from the direction of the arrow D3 shown in FIGS. 1 and 2, and FIG. 6 is a view when the case is viewed from the direction of the arrow D4 shown in FIGS. It is a figure (bottom view). 7 is a cross-sectional view along AA (vertical cross-sectional view) in FIG. 1, and FIG. 8 is a cross-sectional view along BB (transverse cross-sectional view) in FIG.

  The case 1 has a case body 10 made of a resin such as polycarbonate, and the case body 10 has an opening 11 formed therein. The opening 11 is formed so as not to block the photographing lens provided in the portable terminal when the case 1 is attached to the portable terminal. The position, size, and shape of the opening 11 can be determined as appropriate.

  The opening 11 may not be formed. In this case, the photographing lens of the mobile terminal is covered by the case 1, but for example, if the case 1 is provided with a structure that relatively slides the case 1 and the mobile terminal, the case 1 is not covered with the photographing lens. 1 can be moved.

  The case 1 has four holding portions 12 a to 12 d, and each holding portion 12 a to 12 d protrudes from the case body 10 to the back side of the case 1. The holding parts 12a to 12d are used for holding the portable terminal when the case 1 is mounted on the portable terminal. The holding portions 12a to 12d are provided at positions that do not cover the buttons and terminals provided on the side surface of the mobile terminal. Since the holding parts (12a to 12d) formed on the case body 10 need only hold the portable terminal without covering the buttons of the portable terminal, in consideration of this point, the number of holding parts, The position where the holding portion is provided can be determined as appropriate.

  As shown in FIG. 2, six ribs 13 a to 13 f are integrally formed on the back surface of the case body 10. The ribs 13a to 13f are formed to suppress deformation of the case main body 10. In the present embodiment, a recess 10 a is formed on the front side of the case body 10, and the recess 10 a protrudes on the back side of the case body 10. Here, when the case 1 is attached to the mobile terminal, the bottom surface 10a1 of the recess 10a is closest to the mobile terminal, and the region of the case body 10 excluding the recess 10a is separated from the mobile terminal.

  For this reason, the case main body 10 is easily deformed in a region away from the mobile terminal. Therefore, in the present embodiment, the deformation of the case body 10 is suppressed by forming the ribs 13a to 13f in the region of the case body 10 excluding the recess 10a.

  Here, since the dimension of the case main body 10 in the vertical direction of FIG. 2 is longer than the dimension of the case main body 10 in the horizontal direction of FIG. 2, the case main body 10 is easily deformed (curved) in the vertical direction of FIG. . Therefore, in the present embodiment, as shown in FIG. 2, the above-described deformation (curvature) of the case body 10 is formed by forming ribs 13 a to 13 f extending in the longitudinal direction of the case body 10 (vertical direction in FIG. 2). I try to suppress it.

  Note that the ribs (13a to 13f) formed on the case main body 10 need only be able to suppress deformation of the case main body 10. Therefore, in consideration of this point, the number of ribs and the positions where the ribs are formed are appropriately determined. it can.

  As shown in FIG. 1, a ring 20 is disposed in the recess 10 a of the case body 10. The ring 20 includes a ring main body 21, a spherical portion 22, and a connecting portion 23 that connects the ring main body 21 and the spherical portion 22. Both end surfaces of the ring main body 21 in the left-right direction in FIG. 7 are constituted by flat surfaces 21a.

  In the present embodiment, the ring body 21 is formed in an annular shape, but may be formed in other shapes. For example, the ring body 21 can be formed in a polygonal ring shape, or the ring body 21 can be provided with ends separated from each other without forming the entire ring body 21 into a continuous ring shape. Here, the recessed part 10a should just be formed along the shape of the ring main body 21 so that the ring main body 21 can be accommodated.

  As shown in FIG. 1, a part of the spherical portion 22 is covered with the case main body 10 so that the spherical portion 22 does not come out of the case main body 10. In FIG. 1, the outer shape of the spherical portion 22 is indicated by a dotted line. The spherical portion 22 is slidably attached to the case body 10.

  As shown in FIG. 1, the operation part 30 is provided inside the recessed part 10a. The operation unit 30 is pushed by the user in order to cause the ring main body 21 accommodated in the recess 10a to protrude outside the recess 10a. The operation method of the operation unit 30 will be described later.

  The operation unit 30 protrudes from the bottom surface 10a1 of the recess 10a to the surface side of the case body 10, and the ring body 21 is accommodated in a space formed between the operation unit 30 and the recess 10a. Further, the operation unit 30 is formed integrally with the bottom surface 10a1 of the recess 10a only in the region R shown in FIG. This point will be described in detail with reference to FIG. FIG. 9 is a diagram in which the ring 20 is omitted from the structure shown in FIG.

  As shown in FIG. 9, except for the region R, the operation unit 30 is not connected to the bottom surface 10a1 of the recess 10a. And the notch C is formed in the bottom face 10a1 of the recessed part 10a. Thereby, when the operation part 30 is pushed in from the surface side of the case body 10, a part of the operation part 30 can enter the inside of the notch C while elastically deforming the connection part of the operation part 30 and the recess 10 a. it can. Here, the notch C is formed so that the operation unit 30 does not interfere with the recess 10a when the operation unit 30 is pushed.

  The operation part 30 is provided with a claw part 31. As can be seen from FIG. 9, the claw portion 31 is provided on the operation portion 30 on the side opposite to the connection portion (region R) between the operation portion 30 and the recess 10 a. The position where the claw portion 31 is provided is not limited to the position shown in FIG. That is, it is only necessary that the claw portion 31 can move in the pushing direction when the operation portion 30 is pushed in, and the position where the claw portion 31 is provided can be determined in consideration of this point. Specifically, the claw portion 31 can be provided at a position different from the connection portion (region R) between the operation portion 30 and the recess 10a.

  As shown in FIG. 1, when the ring body 21 is accommodated in the recess 10 a, the claw portion 31 contacts a part of the ring body 21. As described above, when the operation unit 30 is pushed in from the surface side of the case body 10, the claw portion 31 moves toward the inside of the ring body 21.

  As shown in FIG. 2, a sheet-like stopper 41 is disposed on the back side of the case body 10. Here, the two pins 42 provided on the case body 10 are used to fix the stopper 41 to the case body 10. The pin 42 can be omitted.

  As shown in FIG. 7, the stopper 41 is disposed at a position corresponding to the spherical portion 22. The spherical portion 22 is incorporated into the case main body 10 from the back side of the case main body 10, but the stopper 41 is arranged so that the spherical portion 22 does not come out to the back side of the case main body 10.

  A friction material 43 is disposed between the spherical portion 22 and the stopper 41. A part of the friction material 43 is formed in a shape along the spherical portion 22 in contact with the spherical portion 22. The friction material 43 is used to give a frictional resistance to the contact surface of the spherical portion 22. As the friction material 43, for example, rubber can be used. As shown in FIG. 7, a part of the friction material 43 is inserted into a hole 41 a formed in the stopper 41. Thereby, the friction material 43 can be positioned with respect to the stopper 41.

  In the present embodiment, the spherical portion 22 is incorporated in the case body 10 and the ring 20 is moved with the spherical portion 22 as a reference, but the present invention is not limited to this. That is, a part of the ring 20 is slidably attached to the case body 10 so that the ring body 21 can move between the position accommodated in the recess 10a and the position pulled out from the recess 10a. It only has to be done. For example, similarly to the ring part described in Patent Document 1, two legs can be provided on the ring 20 and these legs can be inserted into holes provided in the case body 10. Thereby, the ring main body 21 can be rotated between the position accommodated in the recessed part 10a and the position pulled out from the recessed part 10a centering on the leg part.

  Next, an operation method of the operation unit 30 will be described with reference to FIGS. 10 and 11. 10 and 11 correspond to enlarged views of a part of FIG.

  When the operation unit 30 is pushed in the direction of the arrow F1 shown in FIG. 10 by a user's finger or the like, a part of the operation unit 30 (portion connected to the recess 10a) is elastically deformed, so that the claw portion 31 is moved to the direction indicated by the arrow F1. Try to move in the direction. Since the nail | claw part 31 is located above the ring main body 21, if it tries to move to the direction of arrow F1, the ring main body 21 will be pressed on the bottom face 10a1 of the recessed part 10a. At this time, the ring body 21 receives a reaction force in the direction of the arrow F2 from the bottom surface 10a1 of the recess 10a.

  When the operation unit 30 is continuously pushed, the claw portion 31 slides along the outer surface of the ring body 21 and moves to the inside of the ring body 21. Thereby, the pressing of the ring main body 21 by the claw portion 31 is released. However, since the ring main body 21 receives the reaction force in the direction of the arrow F2 as described above, as shown in FIG. Move outward. That is, the ring body 21 protrudes from the surface of the case body 10. Here, since the spherical portion 22 is in contact with the friction material 43, the ring body 21 is maintained at a position protruding from the surface of the case body 10 by the frictional resistance between the spherical portion 22 and the friction material 43. . That is, it is possible to prevent the ring body 21 protruding outside the recess 10a from returning to the inside of the recess 10a.

  In this embodiment, since the claw part 31 is provided in the operation part 30 on the opposite side to the connection part (area | region R) of the operation part 30 and the recessed part 10a as mentioned above, when the operation part 30 is pushed in It becomes easy to secure the movement amount of the claw portion 31. Specifically, when the operation unit 30 is pushed in, the operation unit 30 is elastically deformed with the connection portion (region R) between the operation unit 30 and the recess 10a as a base point. By providing the claw portion 31 on the side opposite to the base point, it becomes easy to secure the amount of movement of the claw portion due to the pressing of the operation portion 30.

  This makes it easier to move the claw portion 31 located above the ring body 21 to a position below the ring body 21. If the claw portion 31 is moved in this way, it can be prevented that the claw portion 31 remains in contact with the ring main body 21. When the ring main body 21 tries to move in response to the reaction force in the direction of the arrow F2, if the claw portion 31 remains in contact with the ring main body 21, the ring main body 21 is prevented from moving, and the ring main body 21 is prevented from moving from the surface of the case main body 10. It becomes difficult to make the main body 21 protrude. In the present embodiment, after the claw portion 31 moves to the inside of the ring main body 21, the claw portion 31 can be moved to a position where it does not contact the ring main body 21. Thereby, it can suppress that the movement of the ring main body 21 is prevented, and it becomes easy to make the ring main body 21 protrude on the surface of the case main body 10.

  The user can easily put a finger on the ring main body 21 protruding from the surface of the case main body 10, and can easily pull out the ring main body 21 to the outside of the recess 10a. When the ring body 21 is pulled out, the ring body 21 can be moved to a position where the connecting portion 23 contacts the case body 10.

  After pulling out the ring body 21 to the outside of the recess 10 a, the user can support the case 1 through the ring body 21 by passing a finger inside the ring body 21. The user can operate the portable terminal to which the case 1 is attached while supporting the case 1 via the ring body 21. Here, since the spherical portion 22 of the ring 20 is slidably attached to the case main body 10, the ring main body 21 can be moved in a predetermined direction with the spherical portion 22 as a reference (center), or the ring main body 21. You can change the orientation.

  On the other hand, as shown in FIG. 12, the ring main body 21 can be used as a support for the case 1 when the case 1 attached to the portable terminal 100 is placed on a placement surface S such as a table. That is, the ring main body 21 is protruded from the surface of the case main body 10, and a part of the ring main body 21 is brought into contact with the mounting surface S, whereby the portable terminal with the case 1 mounted on the mounting surface S. 100 can stand up diagonally. Thereby, the user can use the mobile terminal 100 in a state where the mobile terminal 100 is tilted with respect to the placement surface S.
