The portable terminal device gripping tool according to the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is an overall perspective view of the front side of the portable terminal device gripping tool 1, and FIG. 2 is a plan view of the back side.
The portable terminal device gripping tool 1 includes a main body 11 attached along the back side surface of the mobile terminal device 2, and a grip portion constituting member 3 attached along the back side surface of the main body 11. As shown in FIG. 1, the main body 11 is attached to the back surface of the mobile terminal device 2 provided with the touch panel 22.

  The main body 11 is a thin plate member formed in substantially the same size and the same shape as the mobile terminal device 2 to be mounted in order to be mounted along the back side of the thin plate-shaped mobile terminal device 2. On the front surface side of the main body 11, a housing portion 12 that houses the mobile terminal device 2 is provided. The accommodating portion 12 includes a side wall portion 121 erected on the surface side along the peripheral edge of the main body 11, and a curved portion 122 formed to be curved inward at the upper end portion of the side wall portion 121. An accommodation space 120 for accommodating the mobile terminal device 2 is defined inside the side wall portion 121 and the curved portion 122. At least the side wall part 121 and the curved part 122 of the main body 11 are made of a flexible member such as silicon rubber. When the main body 11 is attached to the mobile terminal device 2, the side wall part 121 and the curved part 122 appropriately expand and contract. By doing so, the portable terminal device 2 can be accommodated in the accommodation space 120. Further, the side wall portion 121 and the curved portion 122 are in close contact with the peripheral end of the mobile terminal device 2 in the storage space 120, so that the mobile terminal device 2 is reliably held in the storage portion 12 of the main body 11. The housing portion 12 configured as described above functions as a mounting portion. Another configuration example of the mounting portion may be a configuration in which the mobile terminal device 2 is attached to the surface of the main body 11 with an adhesive without providing a space for storing the mobile terminal device 2 like the housing portion 12.

  As shown in FIGS. 2 and 3, a grip portion constituting member 3 is attached to the back surface side of the portable terminal device grip 1 of the present invention. The gripping member constituting member 3 is housed in a housing recess 13 as a housing portion formed on the back surface of the main body 11. The storage recess 13 is a recess formed in the same shape on the back surface of the main body 11 at a depth similar to the thickness of the gripping member constituting member 3, and a groove 131 a serving as a locking portion at the opposite end. -E, 132a-e. A plurality of grooves 131a to 131e and 132a to 132e are provided at predetermined intervals, and are provided at opposing positions on opposite edges. Also, as shown in FIGS. 3 and 4, the pair of opposed grooves 131b, 132b / 131c, 132c / 131d, and 132d are locking projections arranged on a line connecting the opposed grooves. Are provided with ridges 133a, 133b, 133c, and 133d.

  On the other hand, as shown in FIG. 2, the gripping member constituting member 3 is a substantially rectangular plate-like member, and protrusions 31a, 32a, 31b, and 32b are provided as engaging portions at four corners. . The gripping member constituting member 3 has a bent portion 33 at the center, and the two plate members 34 a and 34 b are connected via the bent portion 33, and the gripping portion constituting member 3 is bent at the bent portion 33. It has a configuration. The projecting portions 31 a, 32 a, 31 b, and 32 b are provided so as to project in the projecting direction from the end of the end side, that is, in the direction parallel to the folded portion 33, at the opposite end facing the bent portion 33. . As shown in FIG. 2, in the retracted state, the protrusions 31a, 32a, 31b, and 32b are engaged with the grooves 131a, 132a, 131e, and 132e, respectively. Thus, in the stored state, the gripping member constituting member 3 is stored in the main body 11 and is configured to have a flat plane without any protrusion on the back surface of the main body 11.

At one end of the gripping member constituting member 3 configured as described above, for example, as shown in FIG. 3, the protrusions 31a and 32a are removed from the grooves 131a and 132a, and the central grooves 131c and 132c are removed. Engage with. As a result, the gripping member constituting member 3 is configured such that the plate members 34 a and 34 b are separated from the main body 11 and are bent by the bending portion 33, thereby forming the gripping portion 4 having a triangular cross section. That is, it will be in a grasping part composition state. At this time, the ridge 133b contacts the end of the plate member 34a, and assists the engagement between the protrusions 31a, 32a and the grooves 131c, 132c. The protrusions 133a, 133b, 133c, and 133d may not be provided.
By providing a plurality of bent portions 33, the cross-sectional shape of the grip portion 4 can be a polygon other than a triangle. In this case, it is preferable that the bent portion 33 has a structure that bends only in the direction of the mountain shape (for example, a hinge structure).

  By configuring the gripping portion 4 as described above, as shown in FIG. 5, the gripping portion 4 is formed on the back side of the mobile terminal device 2, and the mobile terminal device 2 is easily and reliably held with one hand H0. be able to. In the case of holding with one hand, the end of the side of the touch panel of the mobile terminal device 2 is pressed with the thumb F1, and is gripped over the top of the grip portion 4 with the other fingers such as the index finger F2 and the middle finger F3. As described above, when the hand is held by one hand, since the holding portion 4 having a sufficient volume is provided, the force is easily transmitted from the palm to the portable terminal device 2 and can be firmly supported, and the finger of the other hand can be supported. The screen operation is easy.

  As shown in FIG. 6, the inclination angle of the side surface of each groove may be changed. For example, as shown in FIG. 3, the side surface inclination angles of the groove portions 131a to 131a and 132a to 132e may be adjusted to the angle along the inclination angle of the plate members 34a and 34b constituting the triangle. By setting it as such a structure, it is suppressed that a protrusion part remove | deviates from a groove part. Furthermore, by providing the cover member 134 that covers the grooves 131a to 132e and 132a to 132e, the effect of suppressing the protrusions from being further separated from the grooves is improved. For example, when the cover member 134 is made of a flexible material such as an elastic member, the protrusion 31a engaged with the groove 131a is removed from the groove 131a as shown in FIG. As shown in FIG. 6B, the cover member 134 of the portion to which the groove 131a moves is extended, and the protrusion 31a is pressed toward the main body 11 so as to fit into the desired groove 131c. Encourage Further, the cover member 134 suppresses the clogging of the groove portion due to the intrusion of dust.

As shown in FIG. 7, the elastic members 35 a and 35 b are pasted across the bent portion 33 of the gripping member constituting member 3. The surface to be attached may be the front surface or the back surface. By configuring in this way, the force for returning the bent portion 33 from the bent state to the flat state always works, so that it is possible to easily return from the grip portion configuration state to the stored state.
FIG. 8 is an overall perspective view showing another configuration example, and FIG. 9 is a sectional view of the same. In addition to the bent portion 33a at the center of the gripping member constituting member 3, bent portions 33b and 33c provided in parallel to the bent portion 33 are provided at both ends, and between each bent portion 33b and 33c and both ends. In addition, slide portions 36a and 36b are formed. Each slide part 36a, 36b is slidably provided in the folding direction (left and right direction in FIG. 8) in the storage recess 13, and is configured to be movable to an arbitrary position in the storage recess 13.

  Magnets 37a and 37b as engaging portions are embedded in the central portion of the slide portions 36a and 36b on the housing recess 13 side. On the other hand, on the bottom surface of the storage recess 13, a locking member 133 is embedded as a locking portion covered with a magnetic material at a position facing the magnets 37 a and 37 b of the stored gripping member constituting member 3. . The locking member 133 is continuously arranged along the bending direction of the gripping member constituting member 3, and the magnets 37a and 37b are detachably stopped at any position of the locking member 133 by magnetic force. With such a configuration, when one of the slide portions 36a and 36b is slid in the direction of the other slide portion 36b, the plate members 34a and 34b are separated from the inside of the storage recess 13 and the bent portion 33a is mountain-shaped. The bent portions 33c and 33b are bent in a valley shape, and as a result, the grip portion 4 is formed on one side. By moving the slide part 36b, the grip part 4 can be formed on the opposite side to the state of FIG.

  When the grip portion 4 is formed, the magnet 37a is fixed to the locking member 133 by a magnetic force, so that the disadvantage that the slide portion 36a moves unexpectedly when the grip portion 4 is formed is suppressed. In addition, by previously determining the positions of the slide portions 36a and 36b when the grip portion 4 is formed, it is possible to easily change to the grip portion configuration state. In other words, the ridges 133as, 133bs, 133cs, and 133ds may be provided similarly to the ridges 133a and the like in FIG. Among these, when the grip portion 4 is formed and the terminal is operated, the slide portions 36a and 36b are always attached to the same ridge portion, so that the grip portion 4 having the same size is always formed at the time of use. be able to.

The gripping member constituting member described above is composed of a member having a strength sufficient to withstand the gripping force of the hand, except for the bent portion 33, but as another structural example, a flat plate having no bent portion. The material of the flat plate may be an elastic member. With this configuration, when the projecting portions 31a and 32a are removed from the groove portions 131a and 132a and moved to the other groove portions 131c and 132c, the gripping portion constituting member 3A itself is greatly bent to greatly increase outward from the housing recess portion 13 of the main body 11. The grip portion 4A swelled in an arc shape is formed, and the grip portion is configured. Such a gripping part 4A is slightly deformed by the force of the index finger F2 or the middle finger F3, but the elastic coefficient of the elastic material constituting the gripping part constituting member 3A is adjusted so as to be an appropriate deformation according to the shape of the hand. By doing, it can be set as the grip part 4A which is easy to grip.
Further, by fixing both ends of the gripping part constituting member 3 and making the constituent member of the gripping part constituting member 3 a material having a small elastic coefficient and a large expansion / contraction rate, as shown by an imaginary line in FIG. Alternatively, the gripping portion 4A may be formed by hand-drawing with the fingertip of the middle finger F3 and moving toward one side while stretching the gripping portion constituting member 3.

FIG. 11 is a cross-sectional view of the portable terminal device gripping tool 1 of the present invention showing another configuration example. The storage recess 13B formed in the main body 11 is a rectangular recess formed on substantially the entire surface of the main body 11, similar to the storage recess 13 shown in FIG. It is formed to have substantially the same depth as 3B.
The gripping member constituting member 3B housed in the housing recess 13B is a rectangular plate-like member having the same shape and the same size as the housing recess 13B, and is along the longitudinal direction, that is, the long side direction of the main body 11. A plurality of bent portions 331, 332, 333,... 33n are provided in the direction. This 33n, 332, 333 ... 33n is arrange | positioned in parallel with the long side of the holding | grip part structural member 3B, respectively, and at equal intervals. Each of the folds 331, 332, 333,... 33n is a groove having a V-shaped cross section. At the bottom of the groove of the bent part, the thickness of the gripping part constituting member 3B becomes thinner than the other parts, so that bending at the groove part becomes cheaper.

  Magnets 35a and 35b serving as engaging portions are embedded on the surface of the bent portions 331, 332, 333,. ing. On the other hand, in the storage state of the gripping member constituting member 3B, magnetic bodies 135a and 135b as locking portions are provided in the storage recess 13B at positions facing the magnets 35a and 35b. In the storage state, the magnet 35a and the magnetic body 135a overlap, the magnet 35b and the magnetic body 135b overlap, and the gripping member constituting member 3B is held in the storage recess 13B by the respective magnetic forces. Then, when forming the grip portion 4B, the engagement of either one end (for example, the engagement between the magnet 35a and the magnetic body 135a) is peeled off against the magnetic force of the magnet and wound up. The wound gripping member constituting member 3B forms a gripping portion 4B at the other end. At this time, since the engagement between the magnet 35b at the other end and the magnetic body 135b is maintained, the gripping member constituting member 3B is held in the storage recess 13B.

  In the combination of the magnet and the magnetic body constituting the engaging portion and the locking portion in this embodiment, the magnet and the magnetic body may be provided in reverse. Moreover, the magnetic body which is a latching | locking part by the side of the accommodation recessed part 13B may provide a magnetic body in the whole surface of the accommodation recessed part 13B other than the structure provided in an edge part like FIG. By configuring in this way, the position where the engaging portion is fixed by the magnetic force can be arbitrarily changed, so that the grip portion 4B can be moved to an arbitrary position. Moreover, you may comprise an engaging part and a latching | locking part with a planar fastener other than the combination of a magnet and a magnetic body.

  On the other hand, the bent portion has a V-shaped cross section so that when the bent portion is bent, the inner side surface in the groove comes into contact and does not bend more than a predetermined bending angle. . By adjusting the crossing angle (opening angle of the V-shaped groove) of the V-shaped inner surface, the thickness of the grip portion 4B formed by the grip portion constituent member 3B can be adjusted. For example, by increasing the opening angle of the V-shaped groove, the bending angle at the bent portion increases, and as a result, the thickness (diameter in the cross section) of the grip portion 4B decreases. Further, by reducing the opening angle of the V-shaped groove, the bending angle at the bent portion is reduced, and as a result, the thickness (diameter in the cross section) of the grip portion 4B is increased.

  The configuration shown in FIG. 11 is a configuration in which the gripping member constituting member 3B has a bent portion, but in addition, as shown in FIGS. 12 to 15, it is a configuration without a bent portion. May be. In this case, the gripping member constituting member 3C may be made of a flexible thin plate-like member or other sheet material. Such a member can be curved on an arc as a whole without providing a bent portion, so that it can be rolled up from one end and a gripping portion can be formed at the other end.

  FIG. 12 is a plan view of the back surface of the portable terminal device gripping tool 1 according to the present invention, in which the gripping member constituting member 3 is formed of a flexible member that does not have a bent portion. A storage recess 13C as shown in FIGS. 3 and 11 is formed on the back surface of the main body 11, and a gripping member constituting member 3C having the same size and shape as the storage recess 13C is stored. . One end 31C serves as a winding-up end, and the other end 32C is always fixed to the main body 11 side. Guide members 51a and 51b are arranged on the side edges of the main body 11 along the winding direction of the gripping member constituting member 3C (the horizontal direction in FIGS. 12 and 13). A moving member 52 is installed between the guide members 51a and 51b.

  The moving member 52 is disposed so as to be in contact with the gripping member constituting member 3C, and the gripping member constituting member 3C is sandwiched between the main body 11 and the moving member 52. Both ends of the moving member 52 are positioned inside the guide members 51a and 51b, and are provided so as to reciprocate in the bending direction of the gripping member constituting member 3C. When the moving member 52 moves, the guide members 51 a and 51 b guide the moving member 52 so that the distance between the moving member 52 and the main body 11 is not separated.

  When the gripping part constituting member 3C is in the housed state, as shown in FIG. 12, the moving member 52 is positioned on the fixed end 32C side of the gripping part constituting member 3C. When the gripping portion constituting member 3C is returned to the retracted state after the winding end 31C is wound up to form the gripping portion, the moving member 52 is moved in the direction of the winding end 31C as shown in FIG. As a result, the gripping member constituting member 3C sandwiched between the main body 11 and the moving member 52 returns to the storage state while being housed in the storage recess 13C sequentially from the fixed end 32C side by the moving member 52. Thus, the winding end 31C is housed in the housing recess 13C.

  As shown in FIG. 15, shafts 522 a and 522 b are erected at both ends of the moving member 52, and pinions 521 a and 521 b are connected to the shafts 522 a and 522 b, respectively. On the other hand, pinions 521a and 521b are rotatably connected to each other. FIG. 14 is a cross section showing the relationship between the moving member 52 and the guide members 51a and 51b at both ends. Each pinion 521a, 521b meshes with a rack disposed inside each guide member 51a, 51b. Since the relationship between the pinion 521a and the guide member 51a is the same as the relationship between the pinion 521b and the guide member 51b, the relationship between the pinion 521a and the guide member 51a will be described below, and the relationship between the pinion 521b and the guide member 51b will be described. The description is omitted.

  The guide member 51 a is provided along the side edge of the main body 11, a guide plate 511 a disposed in parallel with the back surface of the main body 11 at a predetermined interval, and a rack disposed between the guide plate 511 a and the main body 11. 53a. A pinion 521a meshes with the rack 53a, and the pinion 521a is rotated by the rack 53a as the moving member 52 moves. Further, since the guide plate 511a guides the moving member 52 so as to suppress the moving member 52 toward the main body 11, the moving member 52 exerts an action of pushing the gripping member constituting member 3C into the housing recess 13C. By such a configuration of the rack and pinion and the action of the guide plate 511a, the action of returning the gripping part constituting member 3C to the housed state is smoothly exhibited.

  In addition to the configuration described above, the gripping device for mobile terminal device of the present invention may be provided in a book-like case that is folded in half and covers the front and back surfaces of the thin plate-like mobile terminal device. In this case, the cover part (back cover) fixed to the back surface of the mobile terminal device is the mounting part, and the back side (surface facing the display screen) of the cover (front cover) that protects the front surface (display screen side) The storage recess 13 and the gripping member constituting member 3 are provided. In use, when the front cover is folded back to the back side of the portable terminal device, the gripping part constituting member 3 is positioned outside, and the state is changed between the storage state along the back cover (mounting part) and the gripping part constituent state. It becomes possible.

As described above, the portable terminal device gripping device of the present invention forms a gripping portion with sufficient volume raised from the back surface of the device, so that the second joint is bent from the index finger to the ring finger (or little finger).
