Description

Posture maintaining device

[0001] The present invention relates to a posture maintaining device for maintaining an open-book posture of a booklet.

[0002] Generally, in many booklets, when an open-book posture is adopted in which the spine is positioned at the center and one half and the other half are positioned on both sides thereof, due to the elastic restoring force of the spine, one half and the other half tend to move in a direction in which they approach each other (that is, the direction in which the booklet closes). Against the user's intention, when the open-book posture of the booklet changes to the closed posture, there arises a problem that the user cannot appropriately view the portion to be viewed.

[0003] In order to suppress such problems, various devices for maintaining the open-book posture of a booklet have conventionally been considered (see, for example, Patent Document 1).

[0004] However, conventional devices have not only been difficult to suitably maintain the open-book posture of a booklet, but have also been difficult to adopt a compact form when not in use.

[0020] Here, for the sake of explanation, the front-to-back, left-to-right, and up-and-down directions in this embodiment will be based on the settings shown in Figure 1.

[0021] This embodiment applies the present invention to a posture-holding device A that maintains the open position of a book or notebook S.

[0022] Generally, in many booklets S, when a double-page spread is adopted with the spine s3 positioned in the center and one half s1 and the other half s2 positioned on either side thereof, the elastic restoring force of the spine s3 makes it easy for one half s1 and the other half s2 to move toward each other. The posture holder A is configured to stably maintain the double-page spread position of the booklet S by engaging with each of the two halves s1 and s2 that tend to move toward each other.

[0023] The posture-holding device A comprises a base body B, a first clip device C1 that is rotatably supported on the base body B and clamps one (left) half s1 of the booklet S in the thickness direction, and a second clip device C2 that is rotatably supported on the base body B and clamps the other (right) half s2 of the booklet S in the thickness direction.

[0024] The first and second clip devices C1 and C2 can be rotated relative to the base body B to selectively adopt a storage position (N) and a usage position (U).

[0025] A locking mechanism G is provided between the base body B and the first clip device C1 to lock the first clip device C1 in the stowed position (N) and the usage position (U). Furthermore, a locking mechanism G is provided between the base body B and the second clip device C2 to lock the second clip device C2 in the stowed position (N) and the usage position (U).

[0026] The following describes in detail each component of posture support device A.

[0030] The intermediate base 1 comprises a top wall 11 having an upward-facing surface 1m, and a peripheral wall 12 extending downward from the peripheral edge of the top wall 11.

[0031] The upward surface 1m of the top wall 11 is set to be substantially flush with the upper surface 4m of the clip member 4 when the first and second clip devices C1 and C2 are in the stowed position (N).

[0032] The edges of the booklet S, which is to be held in an open position, come into contact with the front-facing surface mf or the rear-facing surface mr of the peripheral wall 12.

[0033] The intermediate base 1 has a space sp surrounded by the top wall 11 and the surrounding wall 12. The space sp is open downwards.

[0034] The vertical dimension of the intermediate base 1 is set to be longer than the vertical dimension of the left and right side extensions 2 when viewed from the front or rear. In other words, the intermediate base 1 has a more rigid configuration than the left and right side extensions 2.

[0035] <Left and Right Side Extensions 2> The left and right side extensions 2 are projected outward from the lower part of the peripheral wall 12 at the intermediate base 1. The left and right side extensions 2 extend in the left-right direction.

[0036] The maximum width dimension in the front-to-back direction of the left and right side extensions 2 is set to be approximately the same as the maximum width dimension in the front-to-back direction of the intermediate base 1.

[0037] Each tip 2s of the left and right lateral extensions 2 is provided with a shaft holding portion 21, which is a connecting portion that connects to the first and second clip devices C1 and C2, and a spacer portion 22 that protrudes in a roughly donut shape on the lower side so as to surround the shaft holding portion 21.

[0038] The shaft holding portion 21 rotatably holds the shaft portion jk, which is a connecting portion provided in the first and second clip devices C1 and C2. In this embodiment, the shaft holding portion 21 is provided with protrusions and indentations on the inner circumferential surface of the through hole that can support the shaft portion jk in the vertical direction.

[0039] The spacer portion 22 is in sliding contact with the upward inner surface of the clip base 3 that constitutes the first and second clip devices C1 and C2, more specifically, the bottom surface of the substantially annular recess 3w provided around the shaft portion jk. The spacer portion 22 is for smoothly rotating the first and second clip devices C1 and C2 with respect to the base body B and for providing the locking mechanism G.

[0040] The lower part of the spacer portion 22 is arranged to be disposed within the recess 3w. An engaging convex portion g1 that constitutes the locking mechanism G is provided on the outer peripheral surface of the lower part of the spacer portion 22. The locking mechanism G will be described in detail later.

[0041] Further, at each tip portion 2s of the left and right side extending portions 2, an edge portion 2e that forms a substantially semi-circular arc shape in a plan view and extends outward is provided. The edge portion 2e forms a semi-arc shape with the shaft holding portion 21 as the center point.

[0042] <<First and Second Clip Devices C1 and C2>> The first and second clip devices C1 and C2 are configured to be able to sandwich one half portion s1 and the other half portion s2 of the booklet S in the open posture in the thickness direction.

[0043] The first and second clip devices C1 and C2 have substantially the same structure respectively. The first and second clip devices C1 and C2 are arranged in pairs on the left and right.

[0044] As shown in FIGS. 1, 4 to 8, etc., the first and second clip devices C1 and C2 can adopt a storage posture (N) in which their longitudinal directions are along the left-right direction, which is the longitudinal direction of the base body B.

[0045] Further, as shown in FIGS. 2, 3, 9 to 11, etc., the first and second clip devices C1 and C2 can adopt a use posture (U) in which their longitudinal directions are substantially orthogonal to the left-right direction, which is the longitudinal direction of the base body B.

[0046] The first and second clip devices C1 and C2 that constitute the posture maintaining device A are configured to be able to selectively adopt a storage posture (N) and a use posture (U) separately and independently.

[0047] Although the attachment positions of the first and second clip devices C1 and C2 to the base body B are different, since they have the same structure, the same reference numerals are used for each component for explanation.

[0048] As illustrated in FIGS. 20 and 21, the first and second clip devices C1 and C2 are configured to be able to flexibly sandwich one or the other half portions s1 and s2 of various thickness dimensions.

[0049] The first and second clip devices C1 and C2 include a clip base 3 rotatably connected to the base body B in the horizontal direction, a clip member 4 rotatably supported in the vertical direction with respect to the clip base 3 via a support shaft J, and a torsion coil spring 5 (hereinafter simply referred to as "spring 5") interposed between the clip base 3 and the clip member 4 to urge the front portions of the clip base 3 and the clip member 4 in the approaching direction.

[0050] In this embodiment, the first clip device C1 is connected to the left end portion, which is one end portion of the base body B, and the second clip device C2 is connected to the right end portion, which is the other end portion of the base body B.

[0051] <Clip Base 3> The clip base 3 includes a clip base body 31 extending in a predetermined direction, a lower shaft holding portion 32 standing upright at the longitudinal intermediate portion of the clip base body 31 and holding the support shaft J extending in the horizontal direction, a shaft portion jk which is a connecting portion standing upright on the tip side of the clip base body 31 with respect to the lower shaft holding portion 32, and a recessed portion 3w provided around the shaft portion jk and recessed downward so as to form a substantially annular shape.

[0052] The clip base body 31 is plate-shaped as a whole. The clip base body 31 has a longitudinal direction in the front-rear direction in the use posture (U) and has a longitudinal direction in the left-right direction in the storage posture (N).

[0053] The clip base body 31 includes a lower arm portion 31a located towards the tip of the support shaft J and receiving the biasing force of the spring 5 to press upward one and the other half portions s1 and s2 of the booklet S, and a lower base portion 31b located towards the base end of the support shaft J and biased downward by the spring 5.

[0054] The lower arm portion 31a has a protruding portion t3 at its tip that protrudes upward in a roughly semicircular shape compared to other parts. A shaft portion jk is provided at the base end of the lower arm portion 31a.

[0055] The lower base end portion 31b is the part that is pressed from the outside by the user's fingers when opening the first and second clip devices C1 and C2. A recess 3u is provided on the inner surface of the lower base end portion 31b, where the lower end portion 51 of the spring 5 is disposed.

[0056] The lower shaft holding portion 32 is composed of a pair of upright walls 32a, each of which is provided with a shaft holding hole h for holding the horizontally extending shaft J. The pair of upright walls 32a are arranged parallel to each other. The pair of upright walls 32a are positioned further inward than both ends in the width direction of the clip base body 31.

[0057] Multiple engagement recesses g2 are provided at various locations on the inner circumferential surface of the recessed portion 3w, and are recessed in the direction opposite to the axis portion jk. The engagement recesses g2 constitute a locking mechanism G that locks the first and second clip devices C1 and C2 into predetermined positions, namely the storage position (N) and the usage position (U).

[0058] <Clip Member 4> The clip member 4 comprises a clip member body 41 extending in a predetermined direction, and an upper shaft holding portion 42 protruding from the longitudinal middle portion of the clip member body 41 and holding the support shaft J.

[0059] The clip member body 41 is plate-shaped overall. The clip member body 41 is longitudinal in the front-to-back direction in the usage position (U) and longitudinal in the left-to-right direction in the storage position (N). The clip member body 41 is longitudinal in the same direction as the clip base body 31.

[0060] The clip member body 41 includes an upper arm portion 41a located on the tip side of the support shaft J and receiving the biasing force of the spring 5 to press one and the other half portions s1 and s2 of the booklet S downward, and an upper base portion 41b located on the base side of the support shaft J and being biased upward by the spring 5.

[0061] In this embodiment, the longitudinal dimension of the clip member 4 is set to be shorter than the longitudinal dimension of the clip base 3. More specifically, the longitudinal dimension of the upper arm portion 41a constituting the clip member 4 is set to be shorter than the longitudinal dimension of the lower arm portion 31a constituting the clip base 3. On the other hand, the longitudinal dimension of the upper base end portion 41b constituting the clip member 4 is set to be approximately the same length as the longitudinal dimension of the lower base end portion 31b constituting the clip base 3.

[0062] The upper arm portion 41a has a protruding portion P at its tip that protrudes downward in a substantially semicircular shape compared to other parts. Furthermore, a projection k is provided projecting downward from the central part of the protruding portion P on the upper arm portion 41a. The projection k is capable of locally contacting the upper surfaces of one and the other halves s1 and s2 of the booklet S.

[0063] The upper base end portion 41b is the part that is pressed from the outside by the user's fingers when opening the first and second clip devices C1 and C2. The upper surface side of the upper base end portion 41b is provided with a recess 4w suitable for resting fingers on. The inner surface side of the upper base end portion 41b is provided with a recess 4u where the upper end portion 52 of the spring 5 is disposed.

[0064] The upper shaft holding portion 42 is composed of a pair of hanging walls 42a, each of which is provided with a shaft holding hole v for holding a horizontally extending shaft J. In this embodiment, the pair of hanging walls 42a are positioned outside the pair of upright walls 32a provided on the clip base 3.

[0065] In this embodiment, the clip member 4 is made of a transparent synthetic resin material. Because the clip member 4 is transparent, it offers excellent readability and identifiability of articles (text, illustrations, colors, etc.). In other words, even if the upper arm portion 41a of the clip member 4, which is placed on one half s1 and the other half s2 of the booklet S, covers a particular article, it can still be viewed or identified to a certain extent through the transparent upper arm portion 41a.

[0066] <Spring 5> Spring 5 biases the front part of the clip base 3 and the front part of the clip member 4 to move toward each other at all times.

[0067] The coiled intermediate portion 53 of the spring 5 is supported by the support shaft J.

[0068] The lower end portion 51, which is one end of the spring 5, biases the inner surface of the lower base end portion 31b of the clip base body 31 outward (downward).

[0069] The other end of the spring 5, the upper end 52, biases the inner surface of the upper base end 41b of the clip member body 41 outward (upward).

[0070] <<Locking Mechanism G>> As shown in Figures 18 and 19, the locking mechanism G locks the first and second clip devices C1 and C2 into a predetermined position, i.e., the stored position (N) or the usage position (U), by engaging an engaging projection g1 provided on the base body B with an engaging recess g2 provided on the first and second clip devices C1 and C2.

[0071] The engaging projection g1 is provided at one point on the outer circumferential surface of the lower half of the spacer 22 formed on the left and right side extensions 2. The engaging projection g1 protrudes horizontally from the spacer 22. The engaging projection g1 protrudes toward the center of the base body B in the spacer 22.

[0072] The engaging recess g2 is provided on the front, rear, and inner parts of the inner circumferential surface of the recess 3w provided on the clip base body 31.

[0073] <<Regarding the storage position (N) and usage position (U) of the first and second clip devices C1 and C2>> The posture-holding device A, having the above configuration, has a substantially I-shaped appearance in plan view, formed by the base body B and the first and second clip devices C1 and C2 in the storage position (N).

[0074] Furthermore, when not in use, the posture holder A can take on a rod-like form that extends linearly in a predetermined direction, similar to a writing instrument, by setting the first and second clip devices C1 and C2 to the stored position (N). For this reason, when not in use, the posture holder A can be suitably stored in a general storage container having a storage space that extends in the first direction, such as a pen case.

[0075] Furthermore, the posture support device A, with its base body B and the first and second clip devices C1 and C2 for the usage posture (U), has a roughly H-shaped appearance that allows it to be stable on a mounting surface such as a tabletop when viewed from above.

[0076] The operating position (U) of the first and second clip devices C1 and C2 is any position that allows them to clip one and the other half s1 and s2 of the booklet S. The operating position (U) of the first and second clip devices C1 and C2 is not limited to the case where the tip is positioned in front or below, as shown in the illustrated example, but may also be positioned in the case where the tip is positioned behind or above, for example.

[0077] In other words, the posture-holding device A is not limited to being used in conjunction with the far end (upper end) of a booklet S in an open position as shown in the illustrated example. That is, the posture-holding device A may also be used in conjunction with the near end (lower end) of a booklet S in an open position.

[0078] The posture support device A is not limited to use with a booklet S in an open position lying flat on a surface such as a tabletop. In other words, the posture support device A can also be used with a booklet S in an open position standing upright on a surface such as a tabletop.

[0079] In this embodiment, the locking mechanism G is configured such that even when the front ends of the first and second clip devices C1 and C2 are positioned rearward or upward in the operating position (U), the engaging recesses g2 provided on the first and second clip devices C1 and C2 engage with the engaging projection g1 provided on the base body B, thereby enabling the initial function to be performed.

[0080] As described above, the posture holder A according to this embodiment is for holding the open position of the booklet S. The posture holder A comprises a base body B, a first clip device C1 which is rotatably supported on the base body B and clamps one half s1 of the booklet S in the thickness direction, and a second clip device C2 which is rotatably supported on the base body B and clamps the other half s2 of the booklet S in the thickness direction.

[0081] Therefore, this embodiment provides a posture-holding device A that can suitably maintain the open position of the booklet S, and also offers excellent design flexibility to adopt a compact form when not in use.

[0082] In other words, the posture-holding device A is equipped with two clip devices, the first and second C1 and C2, which are rotatably supported on the base body B. Therefore, even if the thickness of one half s1 and the other half s2 of the booklet S that is to be held open are significantly different, the first clip device C1 can appropriately grip the one half s1 and the second clip device C2 can appropriately grip the other half s2.

[0083] Furthermore, the posture-holding device A has two clip devices, the first and second clip devices C1 and C2, which are rotatably supported on the base body B. Therefore, when not in use, it can assume a compact form suitable for carrying and storage by aligning it with the base body B.

[0084] Each of the first and second clip devices C1 and C2 comprises a clip base 3 rotatably connected to a base body B, and a clip member 4 rotatably supported on the clip base 3.

[0085] Therefore, the first and second clip devices C1 and C2 are configured to be suitable for clamping one and the other halves s1 and s2 with a clip base 3 and a clip member 4 rotatably supported with respect to the clip base 3.

[0086] Furthermore, the clip base 3 is rotatably connected to the base body B. Therefore, in this embodiment, the relative position of the base body B and the clip base 3 is stable, and the clip member 4, which rotates relative to the clip base 3, performs a suitable operation for gripping one and the other halves s1 and s2.

[0087] The longitudinal dimension of the clip member 4 is set to be shorter than the longitudinal dimension of the clip base 3.

[0088] Therefore, the clip member 4 is designed not to excessively obscure the text, images, or colors displayed when the book is open.

[0089] A spring 5, which is a biasing means that biases the tip end of the clip member 4 toward the clip base 3, is interposed between the clip base 3 and the clip member 4.

[0090] Therefore, the first and second clip devices C1 and C2 are capable of suitably clipping one and the other half s1 and s2 of the booklet S by utilizing the biasing force of the spring 5.

[0091] The base body B has a longitudinal direction in the left-right direction, which is the first direction as a whole. The first and second clip devices C1 and C2 can selectively adopt a storage position (N) in which their longitudinal direction is along the left-right direction, which is the first direction, and a usage position (U) in which their longitudinal direction intersects the left-right direction, which is the first direction.

[0092] Therefore, the first and second clip devices C1 and C2 can adopt a suitable storage position (N) when not in use, and a suitable operating position (U) when in use.

[0093] The base body B and the first and second clip devices C1 and C2 in the operating position (U) form a roughly H-shaped appearance in plan view.

[0094] Therefore, the posture support device A has a suitable form that allows it to be stable on a mounting surface such as a tabletop in the usage posture (U).

[0095] The vertical dimension of the intermediate base portion 1, which is the longitudinal middle part of the base body B, is set to be longer than the vertical dimension of the left and right side extension portions 2, which are the longitudinal ends of the base body B, when viewed from the front or rear.

[0096] Therefore, the intermediate base portion 1 of the base body B has excellent rigidity. Moreover, the intermediate base portion 1 of the base body B is easily contacted by the end of the booklet S to be held during use, so that the positioning function of the booklet S relative to the entire posture holder A can be effectively performed.

[0097] A locking mechanism G is provided to lock the first and second clip devices C1 and C2 in the stowed position (N) and the operating position (U).

[0098] Therefore, in this embodiment, the first and second clip devices C1 and C2 are stable in both the stored position (N) and the operating position (U).

[0099] However, the present invention is not limited to the embodiments described in detail above.

[0100] The posture holder may comprise a base body, a clip device rotatably supported on the base body and clamping one half of the booklet in the thickness direction, and a movement restraining means provided on the base body that engages with the other half of the booklet and suppresses movement of the other half in the thickness direction.

[0101] In other words, the posture holder may consist of only one clip device that clamps one half of the booklet in the thickness direction. In this case, the base body will be provided with a movement-restricting means that engages with the other half of the booklet and restricts movement of that other half in the thickness direction. The movement-restricting means may be provided integrally with the base body, or it may be provided relative to the base body so as to be able to change the posture.

[0102] The shape of the base body can be appropriately set without departing from the spirit of the present invention. The base body as a whole may not have an elongated length in the first direction. Furthermore, the base body as a whole may have substantially the same thickness dimension.

[0103] The first and second clipping devices only need to be capable of clipping one and the other half of the booklet in the thickness direction, and their specific configuration is not limited to that shown in the embodiments described above.

[0104] For example, the first and second clipping devices may not be provided with biasing means.

[0105] The first clipping device and the second clipping device may have different configurations.

[0106] In the first and second clip devices, components other than the clip base may be rotatably connected to the base body. Note that components other than the clip base are not limited to clip members, but may include other components provided for connection to the base body.

[0107] The longitudinal dimension of the clip member and the longitudinal dimension of the clip base may be set to approximately the same length. Alternatively, the longitudinal dimension of the clip member may be set to be longer than the longitudinal dimension of the clip base.

[0108] The base body and the first and second clipping devices in the usage position may form a roughly U-shaped appearance in a plan view.

[0109] A locking mechanism may not be provided between the base body and the first and second clipping devices.

[0110] The locking mechanism can be any configuration that can lock the first and second clip devices in the stored position and / or the usage position, and is not limited to those shown in the embodiments described above.

[0111] The orientation in which the first and second clipping devices are used is not limited to an orientation approximately perpendicular to the longitudinal direction of the base body, i.e., the first direction.

[0112] The configuration of the connecting portion that rotatably connects the base body and the first and second clip devices can be varied without departing from the spirit of the present invention. For example, the connecting portion may be composed of a shaft portion protruding from the base body and shaft holding portions provided on the first and second clip devices so as to hold this shaft portion.

[0113] Furthermore, the specific configuration of each part is not limited to the above embodiments, and various modifications are possible without departing from the spirit of the present invention.

[0114] This invention can be used as a posture-holding device to maintain the open position of a booklet.
