Description

Technical Field

[0001] The present invention relates to a cover device for an electronic device, and particularly to one that enables the main body of the electronic device to protrude externally as needed. Specifically, it relates to a cover device for an electronic device such as a notebook-type case that can protrude a part of a portable electronic device such as a portable information processing device like a smartphone equipped with a camera by a rotary slider to a state where the camera can be used while being held by the cover.

Background Art

[0002] In portable electronic devices such as mobile phones and portable information processing devices like smartphones, cases or covers that cover the main body of the electronic device are diversified for the purpose of preventing external obstacles, facilitating portability, and achieving a design effect as an accessory.

[0003] In this type of portable electronic device, generally, a small camera is installed, and when the user uses the camera, it is necessary to ensure that the case or cover provided to cover the main body of the electronic device does not obstruct the view of the camera.

[0004] In consideration of such a need, the inventors have proposed a cover device with a slider that slides in the vertical side direction, which can operate from a state where the entire electronic device is covered (notebook mode) to a state where the edges of the cover protrude outward to a state where the ends in the vertical side direction of the electronic device can use the camera (shooting mode) (Patent Document 1).

[0005] In recent years, a notebook-type case as a commercially available cover for an electronic device provided with a rotating part for flexibly using a smartphone by rotating it from a state where the entire electronic device is covered to a state where the camera part protrudes has also been developed.

[0006] However, with newer electronic devices such as smartphones equipped with multiple cameras (lenses), the size of the device itself can vary greatly depending on the model, and the size, position, and number of cameras can also differ. Some devices have a protruding camera section with a certain thickness, which may make them unsuitable for use with conventional electronic device covers (folio cases).

To protect the camera lens from contacting the inner surface of the surface sheet portion 4 of the cover sheet member 2 when the electronic device 45 is held in place by the cover, the upper surface of the rotating table 13, which serves as the base for the electronic device 45, is positioned at a predetermined height relative to the inner surface of the surface sheet portion 4.

[0010] In addition, preferably in the present invention, double-sided tape or gel material is used as a means for adhesively holding the electronic device 45, and a predetermined height of the upper surface of the rotary table 13 is adjusted according to the thickness of the double-sided tape or gel material. In addition, preferably in the present invention, the rotary table 13 is provided with a rib 13R on the opposite side of the circumference from the lock plate 31, and the lower guide case 12 is provided with stoppers 12S, 12S on the opposite side of the circumference from the non-protruding lock groove 46A and the protruding lock groove 46B of the upper guide case 11, respectively, and the range of sliding operation of the rotary table 13 is set by the rib 13R contacting the stoppers 12S, 12S. In addition, preferably in the present invention, the diameter of the circle on the upper surface of the rotary table 13 is at least 50% of the width length of the surface sheet portion 4. Furthermore, preferably in the present invention, the area of ​​the upper surface of the rotary table 13 is at least 10% of the entire surface sheet portion 4. [Effects of the Invention]

[0011] According to the present invention, a lock plate is provided between an upper guide case and a lower guide case so as to be slidable in the radial direction of the circular shape of the rotary table. A locking portion formed on the tip surface side of the lock plate is pressed and shifted by a pressing spring while sliding it from one edge of the upper guide case to the edge located at the position where the rotary table is rotated within the frame opening to an angle at which the electronic device protrudes outward from that edge, thereby locking it into a non-protruding lock groove or a protruding lock groove provided on one edge and the other edge.

Embodiments for Carrying Out the Invention

[0013] Hereinafter, an embodiment of the present invention will be described in detail while referring to the drawings.

[0014] The cover device 1 for an electronic device according to the present embodiment is made so that the central sheet portion 3 of the cover sheet member 2 made of a horizontally long rectangular sewing material as a whole can be folded in two in the left-right direction (see FIG. 9). Then, the cover device 1 for an electronic device folds the cover sheet member 2 in two and is made to cover and hold an electronic device on which a camera is mounted between the left back sheet portion 6 and the right front sheet portion 4.

[0015] An electronic device holding mechanism 5 is provided on the inner surface of the right front sheet portion 4, while a card storage mechanism 7 for temporarily holding cards that a user always uses is provided on the left back sheet portion 6.

[0016] As shown in FIGS. 1(A) and (B), the electronic device holding mechanism 5 includes an upper guide case 11 made of a circular plate-shaped frame body of a synthetic resin material, and a circular dish-shaped lower guide case 12 made of a synthetic resin material that is overlapped so as to close the frame opening 11A of the upper guide case 11 from below (not shown in the plan view of FIG. 1). These upper guide case 11 and lower guide case 12 function integrally as a guide case 10 that holds a rotary table 13 (rotary slider case) made of a circular synthetic resin material that can rotate so as to slide in the circumferential direction on one end side (the lower side in FIG. 1) of the inner surface of the surface sheet portion 4.

[0017] The circular peripheral edge portion of the upper guide case 11 is configured to be wide so as to project inside the circular peripheral edge portion of the lower guide case 12. Thereby, as shown in FIGS. 3(A) and 4, a sliding space 5A is formed between the bottom surface of the upper guide case 11 and the bottom plate portion 12A of the lower guide case 12 so that the rotary table 13 can slide in the circumferential direction.

[0018] As shown in FIGS. 3(B) and (C), a sliding projection portion 13E is formed on the peripheral edge portion of the rotary table 13 so as to project outward in the radial direction of the circle. The sliding projection portion 13E is guided so as to be sandwiched between the lower surface of the peripheral edge portion of the upper guide case 11 and the upper surface of the bottom plate portion 12A of the lower guide case 12, and can slide in the circumferential direction (clockwise direction or the reverse direction) between the upper guide case 11 and the lower guide case 12.

[0019] As shown in FIGS. 3(B) and (C) with the rotary table 13 turned upside down (reversed), and as shown in FIGS. 4 and 5 of the cross section in the A-A direction and the cross section in the B-B direction thereof, a recess 22 is formed that is surrounded by walls that form a space capable of accommodating a lock plate 31 and a pressing eccentric spring 41 described later and is open downward.

[0020] As shown in Figure 3(C), a sliding groove 23 is drilled in one edge of the rotary table 13 so as to communicate with the recess 22 from the outside, and guide members 24A and 24B are provided so as to connect the opposing guide surfaces 23A and 23B of the sliding groove 23 to the recess 22.

[0021] Thus, when the lock plate 31 is inserted from the outside through the sliding groove 23, the tip of the lock plate 31 can slide in and out of the recess 22 via the connecting surfaces of the guide surfaces 23A and 23B and the guide members 24A and 24B. As a result, as shown in Figures 3(B) and (C), when the lock plate 31 is inserted into the sliding groove 23, the insertion portion 31A of the lock plate 31 is guided and held on the bottom plate portion 12A of the lower guide case 12 by the guide surfaces 23A and 23B and the guide members 24A and 24B.

[0022] At this time, as shown in Figure 4, the rotary table 13 is placed on the surface of the bottom plate portion 12A of the lower guide case 12 with the cavity of the recess 22 facing downwards onto the bottom plate portion 12A of the lower guide case 12. At the same time, the sliding projection 13E is in contact with the circumferential edge of the upper guide case 11 and the lower guide case It is held in a state where it is slidably clamped between the bottom plate portion 12A of -12.

[0023] Furthermore, the lower guide case 12 has a cylindrical protrusion at the center of its circular shape, and this protrusion acts as a fixed axis 12C, engaging with a cylindrical central recess 22C at the center of the circular shape of the rotary table 13, allowing the rotary table 13 to rotate and slide.

[0024] As shown in Figure 3(B), the recess 22 of the rotary table 13 is equipped with a pair of pressure-shifting springs 41 and a lock plate 31, which are arranged parallel to each other with respect to the central recess 22C. In this state, as shown in Figures 5(A) and (B), the rotary table 13 is held between the upper guide case 11 and the lower guide case 12 by pressing the recess 22 against the bottom plate portion 12A of the lower guide case 12. The portion of the recess 22 where the lock plate 31 is provided is shallower than the portion of the recess 22 where the pair of pressure-shifting springs 41 are provided.

[0025] When the lock plate 31 is inserted into the deepest part of the sliding groove 23, the locking portion 31B provided on the rear end side of the lock plate 31 is inserted up to the front end surface of the recess 22, thereby causing the locking portion 31B to close the sliding groove 23.

[0026] In this embodiment, the locking portion 31B of the lock plate 31 has a greater thickness than the insertion portion 31A, and its rear end surface 31C has a shape that protrudes backward in an arc shape, while its front end surface 31D forms a plane that faces the rear end surface 22A of the recess 22. As a result, when the lock plate 31 is pushed to its deepest position, the front end surface 31D of the locking portion 31B is in close proximity to the rear end surface 22A of the recess 22, and at this time the rear end surface 31C of the locking portion 31B is maintained in contact with the inner surface of the periphery of the upper guide case 11.

[0027] In the recess 22 of the rotary table 13, a pressure-shifting spring is provided at a rear position opposite to the sliding groove 23. In this case, the spring that applies a pressure-shifting force to the lock plate 31 in the rotary table 13 consists of a pair of (two) coil springs 41, 41, and these two coil springs 41, 41 push the rotary table 13 toward the sliding groove 23.

[0028] The rear end 41A of the coil spring 41 is locked to the end of the recess 22 of the rotary table 13, thereby allowing the front end 41D of the coil spring 41 to move elastically in the front-rear direction relative to the sliding groove 23.

[0029] In this embodiment, a locking portion 31E is provided at the tip of the insertion portion 31A of the lock plate 31, as shown in Figure 3C, and the front end portion 41D of the coil spring 41 is locked by this locking portion 31E, as shown in Figure 3(B).

[0030] As a result, the lock plate 31 is always locked to the front end 41D of the coil spring 41, so that when the lock plate 31 slides within the sliding groove 23, the lock plate 31 moves in conjunction with the spring action of the coil spring 41 without separating from it.

[0031] In addition to the above configuration, two lock grooves, namely a non-protruding lock groove 46A and a protruding lock groove 46B, are formed on the inner surfaces of the upper edge 11U and the right edge 11R of the upper guide case 11, as shown in Figure 3(A).

[0032] When the electronic device 45 is bonded to the upper surface (planar side surface) of the rotary table 13 via the adhesive layer 44 (Figures 1(A) and 2), the non-protruding lock groove 46A and the protruding lock groove 46B are used to maintain a state in which the locking portion 31B of the lock plate 31 of the rotary table 13 is locked to the upper non-protruding lock groove 46A, in order to position the electronic device 45 within the surface sheet portion 4 of the cover sheet member 2 as shown in Figure 1(A).

[0033] In this case, the user using the electronic device cover device 1 will hold the electronic device 45 in a state where it is not subjected to external impact by holding the electronic device 45 inside the outer edge of the cover sheet member 2.

[0034] In contrast, when using the camera mounted on the electronic device 45, as shown in Figure 2, the rotary table 13 is rotated and slid 90° clockwise in the circumferential direction so that the locking portion 31B of its lock plate 31 is locked into the protruding lock groove 46B.

[0035] At this time, the electronic device 45 is maintained in a state where its upper edge protrudes to the right from the surface sheet portion 4 on the right side of the cover sheet member 2, thereby allowing the user to use the camera of the electronic device 45.

[0036] In the above configuration, when the user uses the electronic device cover device 1, except when using the camera of the electronic device 45, the lock plate 31 of the rotary table 13 is engaged with the non-protruding lock groove 46A of the upper guide case 11, as shown in Figure 1(A).

[0037] At this time, the electronic device 45 does not protrude beyond the surface sheet 4 of the cover sheet member 2, so the user can stably hold, operate, and use the electronic device 45.

[0038] In contrast, when using the camera of the electronic device 45, as shown in Figure 2, the user slides the rotary table 13 to the right, causing the electronic device 45 to protrude towards the right edge of the surface sheet portion 4 of the cover sheet member 2, thereby enabling the camera to be used (see Figures 2 and 8).

[0039] Thus, the electronic device cover device 1 can be easily used in a manner that suits the user's intended purpose.

[0040] In this manner, by clamping and holding the rotary table 13 between the upper guide case 11 and the lower guide case 12 so that the rotary table 13 can slide circumferentially while the recess 22 formed on the inside of the rotary table 13 is pressed against the bottom plate portion 12A of the lower guide case 12, an electronic device holding mechanism 5 can be realized in which the assembly work of the lock plate 31 and the pressure deflection spring 41 inside the rotary table 13 is simplified and the locking operation of the lock plate 31 into the non-protruding lock groove 46A and the protruding lock groove 46B is smooth.

[0041] The sliding motion of the rotary table 13 is performed based on the basic concept shown in Figures 6(A) and (B). In Figures 6(A) and (B), the basic concept is shown in two separate diagrams: one showing the rotary table 13 and the lower guide case 12 integrated into a single unit (left diagram), and the other showing only the upper guide case 11 (right diagram), for easier understanding of the basic concept.

[0042] Specifically, as shown in Figure 6(A), by first maintaining the lock plate 31 in a state where it is locked in the non-protruding lock groove 46A located on the upper edge 11U of the upper guide case 11, the electronic device 45 can be positioned in a state where the camera is not in use, as shown in Figure 1(A).

[0043] From this state, the user slides the rotary table 13 clockwise in a circumferential direction, thereby disengaging the lock plate 31 from the locked state of the unlock groove 46A, as shown in Figure 6(B).

[0044] At this time, the locking portion 31B of the lock plate 31 is released from its locking state with the non-locking groove 46A and comes into contact with the inner side surface of the frame opening 11A of the circumferential edge portion 11E of the upper guide case 11. The lock plate 31 remains pushed into the sliding groove 23 against the biasing force of the pressing biasing spring 41, and slides the rotary table 13 in the circumferential direction while sliding against the circumferential edge portion 11E.

[0045] This sliding motion is achieved by applying a biasing force from the pressure biasing spring 41 to the lock plate 31, allowing the user to feel a certain weight while the sliding motion is performed. This enables the rotary table 13, and therefore the electronic equipment 45, to slide circumferentially while maintaining a stable state.

[0046] In this state, if the user further slides the rotary table 13 in the circumferential direction, eventually the locking portion 31B of the lock plate 31 will be locked into the protruding lock groove 46B, as shown in Figure 6(B).

[0047] At this time, the lock plate 31 changes from a state in which it is sliding on the circumferential edge of the upper guide case 11 due to the biasing force of the pressing bias spring 41 to a state in which it falls into the protruding lock groove 46B and is locked (state shown in Figure 6(B)). This allows the user to slide the rotary table 13, and therefore the electronic equipment 45, with a firm sense of positional sliding.

[0048] Furthermore, as shown in the left diagrams of Figures 6(A) and (B), the rotary table 13 is provided with a rib 13R on the opposite side of the circumference from the lock plate 31. On the other hand, the lower guide case 12 is provided with two stoppers 12S, 12S at the bottom plate portion 12A, at positions on the opposite side of the circumference from the non-protruding lock groove 46A and the protruding lock groove 46B of the upper guide case 11, respectively, to stop rotational sliding by bringing the rib 13R of the rotary table 13 into contact with them. With this configuration, the rotary table 13 can slide within a 90° range from the non-protruding lock groove 46A to the protruding lock groove 46B of the upper guide case 11 via the locking portion 31B of the lock plate 31.

[0049] To ensure smooth rotational sliding when the lock plate 31 of the rotary table 13 begins to rotate from the start point P, a relief (rounded edge) is provided on the rotational direction side edge of the non-protruding lock groove 46A of the upper guide case 11. As a result, the rotary table 13 does not move abruptly and can slide smoothly. No relief is provided on the edge of the non-protruding lock groove 46A opposite to the rotational direction.

[0050] On the other hand, the protruding lock groove 46B of the upper guide case 11 has a relief (rounded edge) on the edge opposite to the direction of rotation. Therefore, when the rotary table 13 returns to the non-protruding locked state, it does not move abruptly, and smooth sliding is possible. The edge of the protruding lock groove 46B in the direction of rotation does not have a relief. The rotational sliding of the lock plate 31 of the rotary table 13 when it returns from the protruding locked state to the start point P can operate smoothly.

[0051] In this way, the user can selectively operate the electronic device 45, which is held in adhesive to the upper surface of the rotary table 13 in the electronic device cover device 1, between two operating states: one in which the electronic device 45 is entirely covered between the back sheet portion 6 and the front sheet portion 4 by the sliding motion of the rotary table 13, and another in which the upper and lower edges of the electronic device 45 protrude outward from the left and right edges of the back sheet portion 6 and the front sheet portion 4 (see Figures 7(A) to (C)).

[0052] Thus, when the rotary table 13 slides from a state in which the lock plate 31 is engaged with the non-protruding lock groove 46A (Figure 7(A)) to a state in which it is engaged with the protruding lock groove 46B (Figure 7(C)), the locking portion 31B of the lock plate 31 moves while sliding in contact with the circumferential edge of the rotary table 13 (Figure 7(B)), and the pressing force received by the lock plate 31 from the circumferential edge is stably supported by the two coil springs 41, 41.

[0053] In this embodiment, it is preferable to use two coil springs 41 when considering the centrifugal force involved in the rotational sliding of the rotary table 13, but other springs, such as bent springs, can also be used.

[0054] In this way, according to the configuration of this embodiment, the electronic device 45, which is supported on the rotary table 13 via the adhesive layer 44, can be slid more stably from the position of the non-protruding lock groove 46A to the position of the protruding lock groove 46B.

[0055] In this embodiment, in particular, even when using a camera lens that has thickness, such as the smartphone shown in Figures 1(B) and 8, the height (thickness) of the rotating table 13, which serves as the base for mounting the electronic device 45, is set to be large in order to protect the lens from contacting the inner surface of the cover sheet member 2. Note that a portion of the electronic device holding mechanism 5 is embedded in the cover sheet member 2, as shown in Figure 1(B). Taking this into consideration, it is preferable to set the height of the rotating table 13 in the electronic device holding mechanism 5 so that there is at least a gap between the smartphone camera lens and the cover sheet member 2.

[0056] Furthermore, using the electronic device cover device 1 of this embodiment makes it easier to take photos at a horizontal angle. Even when cards are placed in the card storage mechanism 7 as a notebook-type cover, the device 1 can be used while remaining vertical, so there is no risk of dropping cards.

[0057] The area of ​​the upper surface of the rotary table 13, which is the surface to which the rotary table 13 and the electronic equipment 45 adhere, is at least 10% of the entire surface sheet portion 4, and preferably 15-30%, and especially 20-25%. When the area of ​​the upper surface is within this range, the electronic equipment 45 can be stably adhered to the rotary table 13, and the sliding operation of the rotary table 13 can be made smooth. The rotary table 13 is preferably installed at a position on the lower half of the surface sheet portion 4.

[0058] Double-sided tape is used as the adhesive layer 44 for bonding and holding the electronic device 45, and the height of the upper surface of the rotary table 13 can be adjusted according to the thickness of the protrusion of the camera lens portion of the electronic device 45 and the thickness of the double-sided tape. In this embodiment, the rotary table 13 is sandwiched and slides between the upper guide case 11 and the lower guide case 12 and is not removable, but an embodiment can also be provided in which a detachable rotary table 13 can be configured so that an appropriate height can be selected from several types of rotary tables 13. In addition, a gel material such as urethane gel can be used as the adhesive layer 44.

[0059] The diameter of the circle on the top surface of the rotary table 13 is at least 50% of the width of the surface sheet portion 4, and is preferably 65-85%, and especially 70-80%. When the diameter of the circle on the top surface is within this range, the electronic equipment 45 can be stably adhered to the rotary table 13, and the sliding operation of the rotary table 13 can be made smooth. [Industrial applicability]

[0060] This invention can be used when carrying electronic devices. Furthermore, this invention can be used as a cover device for electronic devices that prevents the cover from obstructing the camera's field of view and has the functionality to be used flexibly regardless of the model of the electronic device.
