  The present invention provides a bending regulation surface material that can regulate the curvature at the time of bending without a complicated mechanism, or a substantially rectangular planar object covering cover and a support base using the bending regulation surface material. With the goal.

  According to the present invention, a plurality of convex members arranged side by side and a connecting member that connects the convex members to each other so as to be bendable are formed into a planar shape, and at least the convex members protrude inside the bending direction. In the bent state of a desired curvature, the convex member on the inner side in the bending direction is in contact with each other, and is a bending regulating surface material that regulates the curvature.

  The plurality of convex members arranged side by side are arranged in parallel in the width direction orthogonal to the longitudinal direction, or in the longitudinal direction as compared to the rod-shaped or belt-shaped member. It is a concept including arranging a block-like member having a short length in the longitudinal direction in addition to the width direction.

The bending is a concept including bending, bending, winding, or bending.
The connecting member that connects the above-described convex members so as to be able to bend is formed by connecting the non-flexible connecting member to the convex member when the connecting member itself is a flexible member having flexibility. This is a concept including a case where the connection is made to be bendable, or a case where the connecting member itself is made of a flexible member having flexibility and is connected to the convex member so as to be bendable.

  The above-mentioned convex members are in contact with each other, for example, the side surfaces of the convex members are in direct contact with each other, or the convex member coverings that cover the convex members are in direct contact with each other, and the convex members are indirect contact with each other. It is a concept that includes touching.

  By this invention, the curvature at the time of bending can be controlled without a complicated mechanism. Specifically, since a plurality of convex members arranged side by side and a connecting member that connects the convex members so as to be bendable are formed in a planar shape, the bending direction with respect to the planar bending-regulated planar material By applying this force, the planar bending regulating planar material can be bent.

  Further, when the convex members are bent so as to protrude inward in the bending direction, the contact portions of the convex members oppose the force in the bending direction by the contact of the convex members with each other. Bending, that is, bending with a curvature equal to or lower than the curvature of the bent state can be regulated.

  In this way, the bending-regulating planar material is configured in a planar shape with a plurality of convex members arranged side by side and a connecting member that couples the convex members to each other without being provided with complicated curvature regulating means. And only by bending so that the said convex member may protrude inside a bending direction, convex members can contact | abut and the bending state of a desired curvature can be controlled.

As an aspect of the present invention, the convex members can be configured in a block shape and arranged in a plane.
In the block shape, the length in the width direction and the longitudinal direction of the bending regulation surface material are both short, and a plurality of the bending regulation surface materials are arranged in parallel in the width direction and the longitudinal direction, so that It is a shape that constitutes a length and has a predetermined height.

It can be set as the arrangement arranged based on predetermined regularity along two directions. The predetermined rule is the same in all two directions, a linear function that increases or decreases in a predetermined ratio from one direction to multiple directions, and increases (decreases after increasing in a predetermined ratio from one direction to multiple directions). Various rules from one direction to many directions such as a quadratic function such as a quadratic function can be used.
According to the present invention, it is possible to bend in the two directions in which the block shape is arranged and to restrict the bending in the two directions with a desired curvature.

  As an aspect of the present invention, in the bent state, the shape of the contact surface where the convex members contact each other and / or the distance between the contact surfaces in the planar state is set according to the desired curvature to be regulated. Can do.

The shape of the contact surface on which the convex members set according to the desired curvature described above contact each other can be any one of the angle, height, unevenness, or the like of the contact surface, or a combination thereof. In addition, setting the shape of the contact surface where the convex members are in contact with each other and / or the distance between the contact surfaces in a planar state according to the desired curvature to be controlled means that the shape of the contact surface And at least one of the intervals is set based on predetermined regularity along two directions such as a width direction and a longitudinal direction, or a direction intersecting the width direction and the longitudinal direction.

  Further, as an aspect of the present invention, at least a part of the outer side surface in the bending direction can be configured with a high friction coefficient surface having a high friction coefficient and low slipperiness.

  The above-mentioned high friction coefficient surface with high friction coefficient and low slipperiness is composed of rubber or resin with high friction coefficient, or the surface of other material with low friction coefficient is coated, etc. It can be formed by coating with rubber or resin having a high coefficient.

  According to the present invention, for example, by placing on the placement surface in a bent state, the outer side surface in the bending direction can be placed while maintaining a state in which the bending is restricted without sliding on the placement surface.

Further, as an aspect of the present invention, the convex member may be configured to protrude on both surfaces of the planar shape.
According to the present invention, it is possible to regulate the bending with a desired curvature even if the bending-regulating planar material is bent on both the front side and the back side. When the convex members on the front side and the back side are set according to different curvatures, it is possible to regulate the bending of the bending regulating planar material with different curvatures depending on the bending directions on the front side and the back side.

  In addition, since the surface side cover is connected to the covering object by the connecting portion so as to be pivotable, the inclination angle in the supine state can be set to an arbitrary angle by adjusting the pivot angle.

  Moreover, although the above-mentioned substantially rectangular planar object covering cover may connect a surface side cover to a covering target object by a connection part, it is provided with the back surface side cover which coat | covers at least one part of the back surface side of a covering target object. The front side cover is pivotally connected to the back side cover at the connecting part, and the back side cover is fixed to the back side of the object to be covered, and the front side cover is covered by the connecting part via the back side cover. The structure fixed to a target object so that a pivot is possible may be sufficient.

  As an aspect of the present invention, the surface side cover portion is configured to be foldable into a pedestal portion and a height support portion at a position spaced from the connecting portion side by a predetermined distance, and the surface side cover portion is covered with the covering object.

An embodiment of the present invention will be described below with reference to the drawings.
1 and 2 are explanatory views of the unidirectional bending plate 10 on one side. Specifically, FIG. 1 (a) shows a perspective view of the one-sided unidirectional bending plate 10, FIG. 1 (b) shows a perspective view of the bent one-sided unidirectional bending plate 10, and FIG. An enlarged side view of the unidirectional bending plate 10 is shown, and FIG. 2B shows an enlarged side view of the one-side unidirectional bending plate 10 in a bent state.

  The unidirectional bending plate 10 on one side is long in the width direction W and has a trapezoidal cross-section trapezoidal bar member 11 and a sheet-like shape adhered to the bottom surface 11b (FIG. 2A) of the trapezoidal bar member 11 arranged in parallel in the longitudinal direction L. It is comprised with the connection sheet | seat 12 of this.

  More specifically, the trapezoidal bar member 11 has a double inclined trapezoidal shape in which the upper surface 11a and the bottom surface 11b are parallel and the both side surfaces 11c are inclined surfaces, and is made of a resin bar member having resilience.

  The connecting sheet 12 has flexibility and resilience, that is, has a firmness, and further comprises a resin sheet material having a high friction coefficient surface with a low slip property. You may comprise the leather etc. which have property.

  The connecting sheet 12 is bonded and fixed to the bottom surface 11b of the trapezoidal bar member 11 arranged in parallel so that the ends in the longitudinal direction L of the bottom surface 11b of the trapezoidal bar member 11 are in close contact with each other. It is connected.

  The one-side unidirectional bending plate 10 configured as described above has a force for bending in the longitudinal direction L with respect to the one-side unidirectional bending plate 10 (FIG. 1 (b). ), When the arrow A) is applied, the connecting sheet 12 bends in a direction that eliminates the gap S between the side surfaces 11c of the adjacent trapezoidal bar members 11 (see the enlarged view of the part a in FIG. 2 (a)). The bent plate 10 is curved. When the gap S disappears and the side surface 11c of the trapezoidal bar member 11 comes into contact, the one-side unidirectional bending plate 10 is not bent any more and is bent.

The mechanism of the bending restriction of such a one-sided unidirectional bending plate 10 will be described in detail below.
As described above, when the connecting sheet 12 is bent by the force in the bending direction and the side surfaces 11c of the adjacent trapezoidal bar members 11 come into contact with each other, the force in the further bending direction (see the arrow N in FIG. 2B). Even if it acts on the unidirectional bending plate 10 on one side, the reaction force n acts on the contact surfaces of the side surfaces 11c. In addition, the connecting sheet 12 is a stiff sheet state having flexibility and resilience, but since it does not have elasticity, it is balanced with the reaction force n acting on the side surface 11c, and the unidirectional bending plate 10 on one side is balanced. A bending regulation function will occur.

  In addition, since the trapezoidal bar member 11 protrudes only from the one side of the connection sheet 12 with respect to the connection sheet 12, the one-side unidirectional bending plate 10 is the side where the trapezoidal bar member 11 does not protrude, that is, FIG. ) Can be bent without being restricted by the flexibility of the connecting sheet 12.

  Moreover, when the one-side unidirectional bending plate 10 releases the force in the bending direction from the bent state on the upper surface side or the bottom surface side, it can be restored to the planar shape shown in FIG. it can.

  In the above description regarding the one-side unidirectional bending plate 10, the trapezoidal bar members 11 are juxtaposed in a state where the ends in the longitudinal direction L of the bottom surface 11 b of the trapezoidal bar member 11 are in close contact with each other, and connected by the connecting sheet 12. (See FIGS. 3 (a) and 3 (b)), as shown in FIGS. 3 (c) and 3 (d), rectangular rod members 11A having a rectangular cross section are arranged side by side with a predetermined gap S and are connected by a connecting sheet 12. However, the one-side unidirectional bending plate 10A may be configured.

  Thereby, as shown in FIG.3 (d), in the bending state, although the upper part of side surface 11Ac in adjacent rectangular rod member 11A contact | abuts and carries out bending control, the curvature different from the above-mentioned one side unidirectional bending plate 10 is different. Bending will be restricted at. Further, it may be a one-side unidirectional bent plate 10B having a rectangular bar member 11B having a height different from that of the rectangular bar member 11A in the one-side unidirectional bent plate 10A. However, since the height of the side surface 11Bc with which the upper part abuts is different, the curvature to be bent is different.

  More specifically, in the latter case, the one-sided one-way bent plate 10A in which the rectangular bar members 11A are arranged side by side with the same gap S and the one-sided one-way bent plate 10B in which the rectangular bar members 11B having a low height are arranged side by side. The one-side unidirectional bending plate 10B can be bent with a smaller curvature.

  As described above, the one-side unidirectional bent plates 10, 10A, 10B are configured so that the trapezoidal bar member 11 and the shape of the side surfaces 11Ac, 11Bc of the rectangular bar members 11A, 11B and the gap S between the trapezoidal bar member 11 and the rectangular bar members 11A, 11B. By setting the above, it is possible to realize bending regulation with a desired curvature.

  Further, in the above description, the one-side unidirectional bent plates 10, 10A, 10B having the trapezoidal cross-section trapezoidal bar member 11 and the rectangular cross-section rectangular bar members 11A, 11B have been described, but the trapezoidal bar member 11 and the rectangular bar member 11A. , 11B is not limited to this, and may be a semi-elliptical cross-section, a semi-circular cross-section, a triangular cross-section, or a substantially trapezoidal cross section in which the side surfaces 11c, 11Ac, 11Bc are configured with outwardly projecting curved surfaces, Even in that case, by setting the distance between the side surfaces 11c, 11Ac, 11Bc of the adjacent trapezoidal bar member 11 and the rectangular bar members 11A, 11B and the shape of the side surfaces 11c, 11Ac, 11Bc, the bending regulation with a desired curvature is realized. can do.

  Furthermore, as shown to Fig.4 (a), the trapezoidal bar member 21 may be provided in both surfaces of the connection sheet | seat 22, and you may comprise the both-sides unidirectional bending plate 20. As shown in FIG. In the case of the unidirectional bending plate 20 on both sides, as shown in FIG. 4B, the upper surface side and the bottom surface side can be bent so as to be able to be bent with respect to the force in the bending direction.

  Moreover, even if it is the both-sides unidirectional bending plate 20 provided with the trapezoidal rod member 21 on both surfaces of the connection sheet 22, the shape of the side surface 21c differs between the trapezoidal rod member 21 on the upper surface side and the trapezoidal rod member 21 on the bottom surface side. With the configuration (see FIG. 4C), as shown in FIG. 4D, the curvature of the bending restriction in the bent state toward the upper surface side and the curvature of the bending restriction in the bent state toward the bottom surface side are obtained. Can be different.

  In addition, in the one-sided one-way bent plates 10, 10A, 10B and the two-sided one-way bent plate 20, all the trapezoidal bar members 11, 21 and the rectangular bar members 11A, 11B are integrally and closely covered with a covering material. Also good. In this case, the side surfaces 11c, 11Ac, 11Bc, and 21c of the trapezoidal bar member 11, the rectangular bar members 11A and 11B, and the trapezoidal bar member 21 are in contact with each other through the covering material in a bent state, and the bending is restricted.

  Next, the one-side two-way bending plate 30 will be described with FIG. 5 showing a perspective view of the one-side two-way bending plate 30 and FIG. 6 showing a perspective view explaining the bending of the one-side two-way bending plate 30.

  The one-sided bi-directional bending plate 30 includes a quadrangular frustum-shaped block member 31 and a bottom surface 31b of the quadrangular frustum block members 31 arranged in parallel in the longitudinal direction L and the width direction W, that is, in a lattice shape (FIG. 2 ( The sheet-like connecting sheet 32 adhered to a)).

  More specifically, the quadrangular pyramid block member 31 has a quadrangular frustum shape in which the upper surface 31a and the bottom surface 31b are parallel and the side surface 31c is an inclined surface, and is made of a resin block member having resilience. .

  The connection sheet 32 has the same flexibility and resilience as the connection sheet 12 of the above-described one-side unidirectional bending plate 10, that is, is composed of a solid resin sheet material. You may comprise the leather etc. which have.

  The connecting sheet 32 is adhesively fixed to the bottom surface 31b of the quadrangular frustum block member 31 in a state where the end portions in the longitudinal direction L and the width direction W of the bottom surface 31b of the quadrangular frustum block member 31 are in close contact with each other. And the square frustum block members 31 are connected.

  The one-sided bi-directional bending plate 30 configured in this way is acted on the one-sided bi-directional bending plate 30 in a longitudinal direction L as shown by an arrow A in FIG. In the same manner as described above, the bending can be restricted not only by bending in the longitudinal direction L but also by bending a force in the width direction W by bending it in the width direction W.

  In addition, since the mechanism of the bending control in the one-sided two-way bending plate 30 is the same as the mechanism of the bending control in the longitudinal direction L in the one-sided one-way bending plate 10, detailed description is omitted.

  In addition, the above-described one-sided bi-directional bending plate 30 has the square frustum-shaped square frustum block members 31 arranged side by side in a lattice shape, but as shown in FIGS. 7 (a) and 7 (b), it has a truncated cone shape. You may comprise, and as shown to FIG.7 (c), (d), you may arrange staggered. Of course, as described above for the one-sided one-way bent plate 10, the one-sided two-way bent plate 30 can be realized by setting the interval between the trapezoidal bar members 11 and the shape of the side surface 11c so as to realize the bending restriction with a desired curvature. The interval between the quadrangular pyramid block members 31 and the shape of the side surface 31c can be set, and the bending can be regulated with desired curvatures in the longitudinal direction L and the width direction W.

  Furthermore, by setting the interval between the truncated pyramidal block members 31 and the shape of the side surface 31c in the longitudinal direction L and the width direction W, the bending is regulated with desired curvatures in the longitudinal direction L and the width direction W, respectively. Can do.

  Of course, similarly to the bilateral unidirectional bending plate 20, the bilateral bilateral bending plate can be configured by providing the truncated pyramid block members 31 on both surfaces of the connecting sheet 32.

  Further, in the one-sided bi-directional bending plate 30, all of the quadrangular pyramid block members 31 may be integrally and closely covered with a covering material. In this case, the side surface 31c of the quadrangular frustum block member 31 comes into contact with the covering material in a bent state, and the bending is restricted.

  Next, the tablet cover (100, 200) using the above-described one-side one-way bent plate 10 or one-side two-way bent plate 30 will be described. First, the one-way tablet cover 100 using the one-side one-way bending plate 10 will be described with reference to FIGS.

  8 shows an explanatory view of the one-way tablet cover 100, and FIG. 9 shows an explanatory view of a stand function of the one-way tablet cover 100. Specifically, FIG. 8A shows a perspective view of the unidirectional tablet cover 100 in the open state, and FIG. 8B shows a perspective view of the unidirectional tablet cover 100 in the closed state.

FIG. 9 (d) shows a side view of the second tilt state, and FIG. 9 (e) shows a side view of the screen operation tilt state.

  The one-way tablet cover 100 includes a touch panel 401 on the surface, as indicated by a dotted line in FIG. 8A, and the surface of the tablet-type mobile terminal 400 having a substantially rectangular shape in plan view, which is configured by a long side 402 and a short side 403. The cover body covers the back surface.

  The one-way tablet cover 100 includes a front cover portion 110 that covers the touch panel 401 in the closed state illustrated in FIG. 8B and a back cover portion that is fixed to the back surface of the tablet mobile terminal 400 and covers the back surface of the tablet mobile terminal 400. 120 and a bending connection portion 130 that bendably connects the front cover portion 110 and the rear cover portion 120 at the side of the long side 402 of the tablet-type mobile terminal 400 having a substantially rectangular shape in plan view. Yes.

  The front cover part 110 and the back cover part 120 have a rectangular shape in plan view that is slightly larger than the planar size of the tablet-type mobile terminal 400 having a substantially rectangular shape in plan view. The length in the longitudinal direction L is slightly longer than the thickness.

  The front cover portion 110 includes, in order from the opposite side in the longitudinal direction L to the bending connection portion 130, the first flat plate portion 111, the one-sided one-way bent plate portion 112 having the same configuration as the one-sided one-way bent plate 20, and the second The flat plate portion 113 is used.

  In addition, the 1st plane plate part 111 and the 2nd plane plate part 113 are plate parts which have the shape retainability which does not curve in the front and back direction in a normal use state, and the 1st plane plate part 111 is the 2nd plane plate part. The length 113 is about half the length in the longitudinal direction L.

  Further, the first flat plate portion 111 and the one-sided one-way bent plate portion 112, and the one-sided one-way bent plate portion 112 and the second flat plate portion 113 are integrated so as to be bendable in the front and back directions.

  Further, the surface of the front cover part 110 (the surface in the closed state shown in FIG. 8A) is coated with a non-slip function, and the rear surface of the front cover part 110 (on the side facing the touch panel 401 in the closed state). The bar-shaped convex part 112a corresponding to the trapezoidal bar member 11 of the unidirectional bending plate 10 on one side protrudes on the surface).

  As shown in FIG. 8A, the unidirectional tablet cover 100 configured as described above fixes the back cover portion 120 to the back surface of the tablet-type mobile terminal 400, and the front cover portion 110 is attached to the tablet by the bent connection portion 130. By pivoting in a direction away from the mobile phone 400, the touch panel 401 of the tablet mobile device 400 can be opened.

  Further, by pivoting the front cover 110 to the touch panel 401 side of the tablet-type mobile terminal 400 from the above-described open state, the back cover 120 and the front cover are formed as shown in FIG. The tablet portable terminal 400 can be sandwiched and covered with the cover part 110.

  In addition, when placed on the placement surface 410 such as the upper surface of the table in the above-described open state, the tablet portable terminal 400 can be operated by performing an operation input on the touch panel 401. However, such a tablet-type portable terminal 400 has a usage method in which, for example, video is output on the touch panel 401 for viewing, but as shown in FIG. It is necessary to look into the image displayed on the touch panel 401 from above, and it is not a suitable placement state at the time of viewing the image, for example.

Therefore, as shown in FIG. 9, the one-way tablet cover 100 can hold the tilted posture of the tablet portable terminal 400 according to use.
Specifically, since the one-way tablet cover 100 has the above-described configuration, it is in an upright posture in the closed state as shown in FIG. Further, as shown in FIG. 9B, the above-described upright posture can be maintained even if the front cover part 110 is pivoted to the back side of the back cover part 120 by the bent connection part 130.
