Similarly, for the Y direction, the direction toward the one side (upper side in FIG. 3) in the longitudinal direction of the spine member 14 is referred to as the Y1 direction, and the direction toward the other side (lower side in FIG. 3) is referred to as the Y2 direction. There is also.

2. Description of Hinge Mechanism A configuration example of the hinge mechanism 19 that connects the housing members 12A and 12B will be described. FIG. 4 is an enlarged perspective view of a main part in a state where the spine member 14 is omitted from the portable information device 10 shown in FIG.

  As shown in FIG. 3, the hinge mechanism 19 is disposed at a position that overlaps both longitudinal ends of the spine member 14. Each hinge mechanism 19 is provided at a position outside the outer shape of the display 16 and has a line-symmetric structure. The hinge mechanism 19 includes a first hinge housing 28A, a second hinge housing 28B, a first arm 30, and a second arm 31.

  The first hinge housing 28A is a thin block-shaped component made of resin, metal, or the like. The first hinge housing 28A is fixed on the inner surface of the first housing member 12A using a fixing screw 32. The second hinge housing 28B is a thin block-shaped component made of resin, metal, or the like. The second hinge housing 28B is fixed on the inner surface of the second housing member 12B using the fixing screw 32.

  28 A of 1st hinge housing | casings have the concave-shaped part 34 in the back surface side which lands on the inner surface of 12 A of 1st housing members. The concave portion 34 is a concave shape that opens from the inner side surface of the first hinge housing 28A (the side surface on the Y2 side in the upper hinge mechanism 19 in FIG. 3) to the side surface on the bending center C side (side surface on the X2 side). (See also FIGS. 7A-8). The second hinge housing 28B has a concave portion 35 on the back surface side that lands on the inner surface of the second housing member 12B. The concave portion 35 is a concave shape that opens from the inner side surface of the second hinge housing 28B (the side surface on the Y2 side in the upper hinge mechanism 19 in FIG. 3) to the side surface on the bending center C side (side surface on the X1 side). (See also FIGS. 7A-8). The concave portions 34 and 35 communicate with each other across the bending center C (see FIGS. 3 and 7B).

  One end of the first arm 30 is rotatably connected to the first hinge housing 28A via the first hinge shaft 36a, while the other end is second to the second hinge housing 28B. It is connected via a hinge shaft 36b so as to be rotatable (see also FIGS. 7A and 7B). One end of the second arm 31 is rotatably connected to the second hinge housing 28B via the third hinge shaft 36c, while the other end is fourth with respect to the first hinge housing 28A. The hinge shaft 36d is pivotally connected (see also FIGS. 7A and 7B).

  The first arm 30 and the second arm 31 are arranged in parallel in the Y direction. The second hinge shaft 36b of the first arm 30 is located between the third hinge shaft 36c and the fourth hinge shaft 36d of the second arm 31. The third hinge shaft 36c of the second arm 31 is located between the first hinge shaft 36a and the second hinge shaft 36b of the first arm 30. Thereby, the 1st arm 30 and the 2nd arm 31 shift in position in the X direction and the Y direction, and are located in a line.

  In each hinge mechanism 19, when the space between the housing members 12A and 12B is folded around the bending center C, the arm members 30 and 31 rotate via the hinge shafts 36a to 36d (see FIG. 4). Thereby, the hinge mechanism 19 is connected so that rotation is possible from the state which folded between the housing | casing members 12A and 12B to the state opened in flat form.

3. Description of spine cover member The spine cover member 14 will be described. In the storage form shown in FIG. 1, the inner end surfaces 12Aa and 12Ba between the housing members 12A and 12B are largely separated to form a gap (see also FIG. 4). Therefore, in the portable information device 10, the spine member 14 is provided to prevent the elements such as the internal display 16, the main board 20, and the battery device 26 from being exposed by covering the gap. FIG. 5 is an exploded perspective view of the spine member 14. 6A is a cross-sectional view schematically showing a cross-sectional structure taken along the line VIA-VIA in FIG. 6B is a cross-sectional view schematically showing a cross-sectional structure along the line VIB-VIB in FIG.

  The spine member 14 is a member that becomes a spine when the portable information device 10 is folded, and is a thin plate member having flexibility. The spine cover member 14 is provided between the casing members 12A and 12B so as to cover the inner end surfaces 12Aa and 12Ba from the inside while straddling the inner end surfaces 12Aa and 12Ba (see FIGS. 3, 6A, and 6B).

  As shown in FIG. 5, the spine member 14 includes a sheet-like member (flexible sheet-like member) 40, a first support member 42, a second support member 43, and a plurality of reinforcement members 44a, 44b, 44c, 44d.

  The first support member 42 and the second support member 43 are thin plate-like members extending in the longitudinal direction (Y direction) of the spine member 14. The reinforcing members 44 a to 44 d are thin plate-like members extending in the longitudinal direction of the spine member 14, and are narrower in the X direction than the support members 42 and 43. The reinforcing members 44a to 44d are arranged between the support members 42 and 43 in the X2 direction from the first housing member 12A toward the second housing member 12B. The first support member 42, the second support member 43, and the reinforcing members 44a to 44d are thin plate members formed of resin, metal, or the like.

  The sheet-like member 40 is a fiber reinforced resin plate in which a reinforced fiber such as carbon fiber is impregnated with a thermosetting resin such as an epoxy resin. The sheet-like member 40 is a thin sheet-like member having a thickness of, for example, 0.3 mm or less, and has flexibility and high strength. Various materials such as metal fibers such as stainless steel fibers and inorganic fibers such as glass fibers may be used as the reinforcing fibers. The sheet-like member 40 may be formed of a resin film, a metal foil, or the like.

  Each support member 42 and 43 and each reinforcement member 44a-44d are fixed to the surface of the sheet-like member 40 using an adhesive agent or a double-sided tape. Each support member 42 and 43 and each reinforcement member 44a-44d and the sheet-like member 40 may be integrally molded. Thereby, the spine member 14 can be folded along with the folding operation of the housing members 12A and 12B. In the sheet-like member 40, a portion covering the inner end faces 12Aa and 12Ba of the housing members 12A and 12B becomes a bent portion 40a (see FIGS. 6A and 6B). The sheet-like member 40 has a plurality of notches 40b arranged in the Y direction at the edge on the second support member 43 side.

  The first support member 42 is provided on the inner surface side of the first housing member 12A so as to be slidable in the X direction between the housing members 12A and 12B along the inner surface. The first support members 42 have pressing surfaces 42a on the surfaces of both ends in the longitudinal direction. The pressing surface 42 a is a surface that is one step lower than the other surfaces of the first support member 42. The first support member 42 has a plurality of X-direction groove portions 42b on the surface of the portion between the pair of pressing surfaces 42a, 42a in the longitudinal direction. The side surface 42c on the X2 side facing the reinforcing member 44a of the first support member 42 is an inclined surface that recedes in the X1 direction from the reinforcing member 44a side in the direction from the back surface side (sheet-like member 40 side) to the front surface side. (See FIGS. 6A and 6B).

  The first support member 42 receives an urging force from a tension spring (elastic member) 45 along the X direction (see FIGS. 3 and 6A). The tension spring 45 constantly urges the spine member 14 along the X1 direction from the second housing member 12B toward the first housing member 12A.

  The second support member 43 is non-slidably attached and fixed to the inner surface of the second housing member 12B on the inner surface side using a fixing screw 46 (see FIGS. 6A and 6B). The 2nd support member 43 has the pressing surface 43a on the surface of both ends in the longitudinal direction, respectively. The pressing surface 43 a is a surface that is one step lower than the other surfaces of the second support member 43. The second support member 43 has a plurality of X-direction groove portions 43b on the surface between the pair of pressing surfaces 43a, 43a. A through hole 47 for inserting the screw portion of the fixing screw 46 is provided at an appropriate position in the longitudinal direction of the second support member 43. The fixing screw 46 is fastened and fixed to the second housing member 12B through the notch 40b of the sheet-like member 40. The side surface 43c on the X1 side facing the reinforcing member 44d of the second support member 43 is an inclined surface that recedes in the X2 direction from the reinforcing member 44d side in the direction from the back surface side (sheet-like member 40 side) to the front surface side. (See FIGS. 6A and 6B).

  Each of the reinforcing members 44a to 44d has a trapezoidal cross-sectional shape in which the upper base and the lower base are slightly curved. On the surface of each longitudinal end of each reinforcing member 44a to 44d, a pressing surface 44e, which is one step lower than the other surfaces, is provided (see FIG. 5). Each pressing surface 44e is formed at a height position substantially the same as the pressing surfaces 42a and 43a of the support members 42 and 43 (see FIG. 7B). The number of reinforcing members 44a to 44d can be changed as appropriate.

  Each of the reinforcing members 44a to 44d has a side surface 48a on the first support member 42 side (X1 side) and a side surface 48b on the second support member 43 side (X2 side) (see FIGS. 6A and 6B). The two reinforcing members 44a and 44b close to the first support member 42 side and the two reinforcing members 44c and 44d close to the second support member 43 side are mutually based on the boundary line between the central reinforcing members 44b and 44c. It is a substantially line-symmetric shape. The side surface 48a of the reinforcing member 44a is an inclined surface that recedes in the X2 direction from the first support member 42 side in a direction from the back surface side (sheet-like member 40 side) toward the front surface side. The side surface 48b of the reinforcing member 44d is an inclined surface that recedes in the X1 direction from the second support member 43 side in a direction from the back surface side (sheet-like member 40 side) to the front surface side. The other side surfaces 48a and 48b face the side surfaces 48b and 48a facing each other substantially in parallel, or are inclined surfaces in a direction slightly spaced from each other.

  In the storage configuration shown in FIG. 6A, the reinforcing members 44 a to 44 d are in contact with each other on the inner surface side of the bent portion 40 a of the sheet-like member 40 that is folded in half, and the plurality of teeth are gaps. An arch shape (arc shape) is formed as if they are arranged side by side. At this time, the outer side surfaces 48a and 48b of the reinforcing members 44a and 44d at both ends are in contact with the side surfaces 42c and 43c of the support members 42 and 43, respectively. With this arch shape, the reinforcing members 44a to 44d function as struts that firmly support the housing members 12A and 12B in the storage form in which the inner end surfaces 12Aa and 12Ba are separated from each other and the rigidity is reduced. That is, the back cover member 14 between the housing members 12A and 12B is in the storage form, and the hinge mechanisms 19 are provided at both ends in the Y direction, but the portions other than the both ends have no rigidity extending in the Y direction. Exists. Therefore, in the portable information device 10, the support members 42 and 43 and the reinforcing members 44 a to 44 b form arch-shaped columns extending in the Y direction, thereby ensuring the rigidity in the thickness direction in the storage form.

  In such a storage configuration, the inner end surfaces 12Aa and 12Ba of the housing members 12A and 12B are disposed at the most spaced positions. For this reason, the spine member 14 is in the retracted position where the first support member 42 side, which is the slide side, is drawn closest to the inner end surface 12Aa side (X2 direction) on the inner surface of the first housing member 12A. At that time, the first support member 42 slides toward the inner end face 12 </ b> Aa against the urging force of the tension spring 45.

  On the other hand, in a usage pattern in which the housing members 12A and 12B are opened in a flat plate shape, the reinforcing members 44a to 44d are arranged in a line with the support members 42 and 43 on the inner surface of the housing members 12A and 12B. The Therefore, the spine member 14 has a flat plate shape with a minimum thickness. In this usage pattern, the inner end surfaces 12Aa and 12Ba of the housing members 12A and 12B are disposed at positions closest to or in contact with each other. For this reason, the back cover member 14 is a forward position where the first support member 42 side which is the slide side has advanced to the outer end surface 12Ab side (X1 direction) opposite to the inner end surface 12Aa side on the inner surface of the first housing member 12A. It becomes. At that time, the first support member 42 smoothly slides to the outer end surface 12Ab side by the urging force of the tension spring 45, so that the spine member 14 does not float or get caught during sliding.

4). Description of the relationship between the spine member and the hinge mechanism The relationship between the spine member 14 and the hinge mechanism 19 will be described. FIG. 7A is a cross-sectional view schematically showing a cross-sectional structure taken along line VIIA-VIIA in FIG. FIG. 7B is a cross-sectional view schematically showing a cross-sectional structure along the line VIIB-VIIB in FIG. FIG. 8 is a cross-sectional view schematically showing a cross-sectional structure along the line VIII-VIII in FIG.

  As shown in FIGS. 1 and 4, the spine cover member 14 extends to a position covering the back side of each hinge mechanism 19, and the hinge mechanism 19 is exposed from between the inner end faces 12 </ b> Aa and 12 </ b> Ba of the housing members 12 </ b> A and 12 </ b> B. To prevent that.

  As shown in FIGS. 3, 7A, 7B, and 8, the spine member 14 has the pressing surfaces 42a, 43a, 44e at both ends in the longitudinal direction so that the back surface of each hinge housing 28A, 28B and the housing member 12A. , 12B. Specifically, the pressing surfaces 42a, 43a, 44e of the spine cover member 14 are inserted and disposed in the concave portions 34, 35 of the hinge housings 28A, 28B. At this time, at least the first support member 42 and the pressing surfaces 42a and 44e of the reinforcing members 44a to 44d are slidably held in the concave portion 34 of the first support member 42, and are concave with the inner surface of the first housing 12A. Guided between the top surface of the unit 34. That is, the concave portion 34 on the first hinge housing 28A side guides the spine cover member 14 so as to be slidable in the X direction, and prevents lifting or the like during sliding. The concave portion 34 has a length that can correspond to the sliding distance (sliding range) L of the spine member 14 (see FIG. 7A). Therefore, the recessed portion 34 is longer in the X direction than the recessed portion 35 on the second hinge housing 28B side.

  As shown in FIG. 8, the hinge mechanism 19 has fitting protrusions 50 on the outer surfaces of the hinge housings 28A and 28B. On the other hand, a fitting recess 52a is formed on the inner surface of the wall portion 52, which is a side wall extending along the X direction from the inner surface of each housing member 12A, 12B facing the fitting projection 50. The fitting concave portion 52a can be fitted with the fitting convex portion 50, and restricts at least the movement of the fitting convex portion 50 in the direction of rising from the inner surfaces of the housing members 12A and 12B.

  Accordingly, the first hinge housing 28A is sandwiched between the inner surface of the first housing member 12A and the top surface of the fitting recess 52a of the wall portion 52, and the lifting is prevented. The second hinge housing 28B is sandwiched between the inner surface of the second housing member 12B and the top surface of the fitting recess 52a of the wall portion 52, so that the floating is prevented. That is, since the hinge housings 28A and 28B are provided with the concave portions 34 and 35 for inserting the spine member 14 on the back surface side, the fixing screw 32 can be fastened only around the concave portions 34 and 35. For this reason, there is a concern that the hinge housings 28A and 28B may be lifted when the hinge mechanism 19 is movable. Therefore, in the portable information device 10, the hinge housings 28 </ b> A and 28 </ b> B are fitted and pressed against the wall portions 52 of the housing members 12 </ b> A and 12 </ b> B to prevent the floating. In addition, you may make each hinge housing | casing 28A, 28B fit to the fitting recessed part 52a, without providing the fitting convex part 50. FIG.

5. Description of Wiring Structure The wiring structure of the portable information device 10 will be described. The portable information device 10 employs a configuration that can be folded in half. For this reason, it is necessary to arrange electronic boards and electronic parts appropriately on the inner surfaces of the left and right housing members 12A and 12B, and to provide them through the inner surface side of the spine member 14 that bends the wirings connecting them. For this reason, there is a concern that the wiring is misaligned when the casing members 12A and 12B are opened and closed, and problems such as pinching and disconnection occur, and it is desirable to prevent the misalignment of the wiring. FIG. 9A is an enlarged cross-sectional view of a main part schematically showing a cross-sectional structure along the alignment direction (X direction) of the grooves 42b and 43b of the spine member 14. FIG. FIG. 9B is an enlarged cross-sectional view of a main part schematically showing a cross-sectional structure along the longitudinal direction (Y direction) of the spine member 14.

  As shown in FIGS. 3, 9A, and 9B, between the first housing member 12A and the second housing member 12B, for example, between the main board 20 and the sub board 24 is electrically connected. A plurality of wirings 54 are provided. The wiring 54 is routed across the housing members 12A and 12B across the inner surface side of the spine member 14. Therefore, the wiring 54 is inserted into the groove portions 42b and 43b in the X direction formed in the support members 42 and 43 of the spine member 14, respectively. In the spine member 14, the height positions of the surfaces of the reinforcing members 44a to 44b substantially coincide with the height positions of the bottom surfaces of the groove portions 42b and 43b (see FIG. 9A).

  Accordingly, since the wiring 54 is stably held in a state of being inserted through the groove portions 42b and 43b, it is possible to prevent problems such as displacement when the casing members 12A and 12B are opened and closed. That is, even when the spine member 14 slides along with the opening / closing operation of the housing members 12A and 12B, the wiring 54 slides in the groove portions 42b and 43b, thereby preventing problems such as misalignment and pinching. Is done. Note that the wiring 54 may be positioned and fixed to one of the housing members 12A and 12B, for example, outside one of the grooves 42b and 43b.

  As shown in FIGS. 9A and 9B, the upper openings of the grooves 42 b and 43 b are covered with the back surface of the support plate 18. For this reason, it is possible to prevent the wiring 54 from floating from the upper openings of the groove portions 42b and 43b and dropping out of the groove portions 42b and 43b. Furthermore, in this embodiment, as shown in FIGS. 9A and 9B, a lid member 56 that closes the openings of the groove portions 42b and 43b is provided to prevent the wiring 54 from falling off from the groove portions 42b and 43b more reliably.

  The lid member 56 is a thin film made of a flexible material such as a thin resin film or metal foil. The lid member 56 is provided over substantially the entire length excluding both ends of the spine cover member 14 in the Y direction and over the full width in the X direction, and is attached to the surface of the spine cover member 14. In the case of this embodiment, a stainless steel sheet-like member (stainless steel sheet) is used for the lid member 56. For example, the end portion (one end portion) on the X2 side is fixed to the surface of the second support member 43, and the end portion (other end portion) on the X1 side is movably mounted on the surface of the first support member 42. (See FIGS. 6A and 6B). For this reason, the lid member 56 follows the slide of the spine cover member 14 and slides on the spine cover member 14 and prevents the wiring 54 from dropping from the grooves 42b and 43b. The lid member 56 may be omitted, and the plate member 18a may be used in place of the lid member 56.

6). Description of Operational Effects of Portable Information Device As described above, the portable information device 10 according to this embodiment includes the one edge portion of the first casing member 12A and the second casing member 12B that are connected by the hinge mechanism 19. A spine provided between the inner surface of the one edge portion of the first housing member 12A and the inner surface of the one edge portion of the second housing member 12B so as to cover the gap between the edge portion of the first housing member 12A A member 14 is provided. The spine member 14 is slidable in the X direction from the second housing member 12B toward the first housing member 12A along the inner surface of the edge of the first housing member 12A. The inner surface of one edge of the second housing member 12B is fixed so as not to slide.

  Therefore, when the first housing member 12A and the second housing member 12B are folded in two via the hinge mechanism 19, the hinge-side edge portions (inner end surfaces 12Aa, 12A, 12 Ba) can be covered with the back cover member 14. For this reason, it is possible to prevent each element such as the internal main board 20 from being exposed from the gap, and to improve the appearance quality and durability of the product. Moreover, the spine member 14 is provided such that one edge portion is slidable with respect to the first housing member 12A, and the other edge portion is fixed to the second housing member 12B. As a result, the spine member 14 slides following the opening / closing operation of the first housing member 12A and the second housing member 12B by the hinge mechanism 19. For this reason, when the space between the two casing members 12A and 12B is opened to reduce the gap between the two casing members 12A and 12B, the spine cover member 14 is prevented from being lifted or displaced in the casing members 12A and 12B. it can.

  At this time, in the portable information device 10, the spine member 14 is fixed so as not to slide on the second housing member 12B side on which the battery device 26 is mounted. That is, among the elements mounted on the portable information device 10, the battery device 26 is particularly required to be as large as possible in order to cope with a high capacity, and has a special shape as compared with the main board 20 and the like. It ’s difficult. Therefore, the spine member 14 has the edge on the battery device 26 side as the fixed side, so that it is not necessary to secure the slide distance L on the battery device 26 side, and can contribute to the miniaturization of the entire device. Of course, the settings on the slide side and the fixed side of the spine member 14 can be changed as appropriate.

  The spine member 14 is fixed to the inner surface of the sheet-like member 40, which is a flexible sheet-like member that can be folded in half, and the first casing member 12A and the second casing member 12B. Reinforcing members 44a to 44b extending in the Y direction along one edge. Thereby, the spine member 14 can reinforce the part which covers the clearance gap between the housing members 12A and 12B folded in half with the reinforcement members 44a-44d. For this reason, it is possible to prevent the spine cover member 14 from being deformed by an external force and damaging each element such as the main board 20 inside. Moreover, since the reinforcing members 44a to 44d are fixed to the sheet-like member 40, it is possible to prevent the smooth folding operation of the spine member 14 from being hindered. Of course, even if the reinforcing members 44a to 44d are omitted and the spine cover member 14 is composed of only the sheet-like member 40, the effect of closing the gap between the housing members 12A and 12B can be ensured.

  The plurality of reinforcing members 44a to 44d form an arch shape in which the side surfaces 48a and 48b are in contact with each other on the inner surface side of the bent portion 40a of the sheet-like member 40 folded in half. Thereby, each reinforcement member 44a-44d functions as a support | pillar which supports firmly between housing | casing member 12A, 12B which folded. For this reason, the thickness of the portable information device 10 can be secured in the thickness direction, the casing members 12A and 12B folded by an external force are crushed, and each element such as the internal display 16 is damaged. Can be prevented.

  In the portable information device 10, the grooves 42 b and 43 b are closed by a lid member 56 made of a metal foil to prevent the wiring 54 from falling off. Therefore, for example, when changing from the storage configuration shown in FIG. 6A to the usage configuration shown in FIG. 6B, the lid member 56 also follows the folding operation of the pair of plate members 18 a, 18 a of the support plate 18. It can be folded together. As a result, the wiring 56 can be reliably prevented from coming into contact with the adjacent end (edge) between the plate members 18a, 18a, and the durability and reliability of the portable information device 10 are improved. Note that the end portion on the X1 side that is the end portion on the slide side of the lid member 56 may be configured to extend beyond the end portion on the X1 side of the first support member 42. Thereby, the wiring 54 can be protected in a wider range than the region where the wiring 54 overlaps the spine member 14.

  It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that the present invention can be freely changed without departing from the gist of the present invention.
