Description

[Technical field]

[0001] The present technology relates to a document stand for storing documents. [Background technology]

[0002] A document storage shelf has been proposed that includes a support rod extending laterally and multiple locking bodies. The support rod has multiple pivot parts, and each locking body has an axle. The axle parts are rotatably inserted into the pivot parts, from which the multiple locking bodies hang. When a locking body is pressed by a document, such as a book or file, the locking body rotates, and the document is sandwiched between the non-rotating locking bodies located on either side of the rotated locking body. In other words, the document can be locked in an upright position even if there is no board or other document next to it (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Publication number 04-029807 Summary of the Invention [Problem to be solved by the invention]

[0004] The locking body is supported only by the shaft portion, and when an external force is applied, stress is concentrated on the shaft portion, making it prone to breakage.

[0005] The present disclosure has been made in consideration of the above circumstances, and has an object to provide a document stand that can prevent damage. [Means for solving the problem]

[0006] A document stand according to one embodiment of the present disclosure has either a pivot or a bearing that rotatably supports the pivot, and is equipped with a plurality of locking portions for locking documents and a holding portion for rotatably holding each locking portion, the holding portion having a plate portion, the other of the pivot or the bearing provided on one side of the plate portion, and a support portion provided on the plate portion at a position away from the other of the pivot or the bearing and supporting the locking portion.

[0007] In one embodiment of the present disclosure, the engaging portion is supported at a plurality of points by providing a supporting portion.

[0008] In one embodiment of the document stand of the present disclosure, the bearing is J-shaped, one end of the bearing is connected to one of the plate portion or the locking portion, and the other end of the bearing faces the other of the plate portion or the locking portion with a gap therebetween, the dimension of the gap being smaller than the diameter of the pivot axis.

[0009] In one embodiment of the present disclosure, the pivot is unlikely to slip out of the gap between the bearing and the plate portion.

[0010] A document stand according to one embodiment of the present disclosure comprises a first side panel protruding from a first edge of the plate portion, a second side panel protruding from a second edge of the plate portion opposite the first edge, a first connecting portion formed on the first side panel, and a second connecting portion formed on the second side panel and connectable to the first connecting portion.

[0011] In one embodiment of the present disclosure, for example, when a plurality of document stands are used, the document stands are lined up by connecting the first connecting portion of one document stand to the second connecting portion of the other document stand.

[0012] In one embodiment of the document stand disclosed herein, the first connecting portion has a first inclined groove inclined with respect to the plate portion and a first protruding portion protruding inwardly from the first inclined groove, and the second connecting portion has a second inclined groove inclined with respect to the plate portion and a second protruding portion protruding inwardly from the second inclined groove, the first connecting portion and the second connecting portion are configured so that the first protruding portion moves along the second inclined groove and is clamped between the second protruding portion and a bottom surface of the second inclined groove, and the second protruding portion moves along the first inclined groove and is clamped between the first protruding portion and the bottom surface of the first inclined groove.

[0013] In one embodiment of the present disclosure, for example, by inclining the first and second inclined grooves so as to descend toward the rear side, even if an external force acts on the connected first and second connecting parts, the first and second connecting parts are unlikely to shift in position in the front-rear and up-down directions. Furthermore, the first and second overhanging parts can be inserted into the first and second inclined grooves from both the front and rear directions. That is, they can be inserted from two directions.

[0014] In one embodiment of the document stand of the present disclosure, the multiple locking portions include a plurality of first locking portions arranged in a direction parallel to the plate portion, and a plurality of second locking portions arranged in a direction parallel to the plate portion below the first locking portions.

[0015] In one embodiment of the present disclosure, a first locking portion is provided on the upper side and a second locking portion is provided on the lower side, making it easier to lock vertically long documents. Effect of the Invention

[0016] In the document stand according to the embodiment of the present disclosure, the support portion is provided so that the locking portion is supported at multiple points, thereby preventing stress from concentrating at one point and causing damage to the locking portion.

The upper bearing 5 is J-shaped and has a straight portion that extends linearly and an arc-shaped curved portion. The straight portion extends in the front-rear direction. The curved portion has both ends positioned above and below, and is curved so as to protrude forward. The rear end of the straight portion is connected to the plate portion 4, and the front end of the straight portion is connected to the lower end of the curved portion. The rear end of the curved portion faces the plate portion 4 with a gap therebetween.

[0027] An opening 4a penetrating from the front to the rear is formed in the plate portion 4 at a portion facing the curved portion of the upper bearing 5. A rib 5a is formed on the upper surface of the straight portion and the inner peripheral surface of the curved portion, in the left-right center of the upper bearing 5. The rib 5a extends from the straight portion of the upper bearing 5 to the inside of the opening 4a.

[0028] The dimension of the gap between the rear end of the curved portion and the plate portion 4 is D. Dimension D is, for example, the dimension of the shortest distance among the dimensions of the gap. Upper bearing 5 is designed to pass through passage 49c (see FIG. 15), which will be described later. Note that upper bearing 5 only needs to be designed to pass through passage 49c, and its shape is not limited to a J-shape.

[0029] The first upper support part 6 is rod-shaped and extends forward and backward. The first upper support part 6 protrudes forward from the plate part 4. The first upper support part 6 protrudes forward further than the upper bearing 5.

[0035] A protrusion 26 that protrudes to the right is formed between the upper guide groove 22 and the lower guide groove 24 in the vertical direction. The protrusion 26 extends in the front-rear direction along the upper guide groove 22 and the lower guide groove 24. The central portion of the protrusion 26 in the front-rear direction is inclined downward toward the rear. The front and rear ends of the protrusion 26 extend linearly in the front-rear direction.

[0036] The first protruding portion 23 protrudes toward the first inclined groove 22a from the upper side of the first inclined groove 22a of the upper guide groove 22. The first protruding portion 23 covers approximately the upper half of the first inclined groove 22a. The first protruding portion 23 has a rectangular shape extending along the first inclined groove 22a when viewed from the right side. A gap is formed between the first protruding portion 23 and the bottom surface of the first inclined groove 22a.

[0037] The first protrusion 25 protrudes toward the first inclined groove 24a from the lower side of the first inclined groove 24a of the lower guide groove 24. The first protrusion 25 covers approximately the lower half of the first inclined groove 24a. The first protrusion 25 has a rectangular shape extending along the first inclined groove 24a when viewed from the right side. A gap is formed between the first protrusion 25 and the bottom surface of the first inclined groove 24a.

[0038] Fig. 10 is a partially enlarged right side view showing the second side plate 30 and the second connecting portion 31, and Fig. 11 is a schematic cross-sectional view taken along line XI-XI in Fig. 10. The second connecting portion 31 includes an upper guide groove 32 formed on the right side surface of the second side plate 30, and a lower guide groove 34 formed on the right side surface of the second side plate 30 and positioned lower than the upper guide groove 32.

[0039] The upper guide groove 32 extends in the front-rear direction. The central portion of the upper guide groove 32 in the front-rear direction forms a second inclined groove 32a that is inclined downward toward the rear. The front end portion of the upper guide groove 32 forms an end groove 32b that extends linearly in the front-rear direction. The rear end portion of the upper guide groove 32 forms an end groove 32c whose upper side surface extends linearly in the front-rear direction and whose lower side surface is inclined downward toward the rear.

[0040] The lower guide groove 34 extends in the front-rear direction. The central portion of the lower guide groove 34 in the front-rear direction forms a second inclined groove 34a that is inclined downward toward the rear. The front end portion of the lower guide groove 34 forms an end groove 34b whose lower side extends linearly in the front-rear direction and whose upper side is inclined downward toward the rear. The rear end portion of the lower guide groove 34 forms an end groove 34c that extends linearly in the front-rear direction.

[0041] A protrusion 36 protruding to the left side is formed between the upper guide groove 32 and the lower guide groove 34 in the vertical direction.

The second protruding portion 35 covers approximately the upper half of the second inclined groove 34a. The second protruding portion 35 has a rectangular shape extending along the second inclined groove 34a when viewed from the right side. A gap is formed between the second protruding portion 35 and the bottom surface of the second inclined groove 34a.

[0044] Since the spaces formed in the first connecting portion 21 and the second connecting portion 31 extend in the front-rear direction, when a mold is used, it can be manufactured using a split mold that is divided into two parts, front and rear, which reduces manufacturing costs compared to when it is divided into three or more parts. The bottom plate 2, plate portion 4, the plurality of upper bearings 5, the plurality of first upper support portions 6, the plurality of second upper support portions 7, the plurality of lower bearings 8, the plurality of first lower support portions 9, the plurality of second lower support portions 10, the horizontal plate 11, the first side plate 20, the first connecting portion 21, the second side plate 30 and the second connecting portion 31 are integrally molded using a two-part split mold.

[0045] 1, a plurality of locking portions 40 are held by the holding portion 3. The plurality of locking portions 40 include an upper locking portion 40 supported by a plurality of upper bearings 5, a plurality of first upper support portions 6, and a plurality of second upper support portions 7, and a lower locking portion 40 supported by a plurality of lower bearings 8, a plurality of first lower support portions 9, and a plurality of second lower support portions 10. The upper locking portion 40 constitutes a plurality of first locking portions, and the lower locking portion 40 constitutes a plurality of second locking portions.

[0046] 12 is a schematic side view of the locking portion 40, FIG. 13 is a schematic plan view of the locking portion 40, FIG. 14 is a schematic bottom view of the locking portion 40, and FIG. 15 is a schematic cross-sectional view taken along line XV-XV in FIG. 13. The locking portion 40 has a first side 41 and a second side 42 that form a horizontally elongated triangular shape. The first side 41 and the second side 42 have the same shape and face each other. The first side 41 and the second side 42 each have a base and two oblique sides. One of the two oblique sides is longer than the other. Hereinafter, one oblique side is also referred to as a long oblique side, and the other oblique side is also referred to as a short oblique side.

[0047] The locking portion 40 has a first inclined surface 43 that is substantially perpendicular to the first side surface 41 and the second side surface 42. The first inclined surface 43 is formed between the long oblique sides of the first side surface 41 and the second side surface 42, and is continuous with the entire long oblique side.

[0048] The locking portion 40 has a second inclined surface 44 that is substantially perpendicular to the first side surface 41 and the second side surface 42. The second inclined surface 44 is formed between the short oblique sides of the first side surface 41 and the second side surface 42, and is continuous with the entire short oblique side.

[0049] A recess 47 formed in a J-shape in side view is formed at the apex where the first inclined surface 43 and the second inclined surface 44 intersect. The recess 47 has a straight portion and a curved portion. The curved portion is located on the first inclined surface 43 side, and the straight portion is located on the second inclined surface side. The curved portion curves so as to protrude toward the base. The portion where the straight portion of the recess 47 intersects with the second inclined surface 44 forms the apex. The recess 47 restricts the movement of the engagement portion 40.

[0050] An opening 48 is formed in the entire second inclined surface 44 and the recess 47. The locking portion 40 has a contact surface 45 that is approximately perpendicular to the first side surface 41 and the second side surface 42. The contact surface 45 is formed between the bases of the first side surface 41 and the second side surface 42 and continues to the entire bases. An opening 45a is formed in the contact surface 45. The opening 45a is formed between a portion where the contact surface 45 and the first inclined surface 43 intersect and a portion slightly closer to the first inclined surface 43 than a portion where the contact surface 45 and the second inclined surface 44 intersect. A plurality of ribs 43a extend from the first inclined surface 43 toward the contact surface 45. The plurality of ribs 43a are aligned along the bases of the first side surface 41 and the second side surface 42 and do not protrude from the opening 45a.

[0051] The locking portion 40 includes a pivot 46. The pivot 46 is formed so as to be sandwiched between the first side surface 41 and the second side surface 42 at the apex portion where the straight portion of the recess 47 and the second inclined surface 44 intersect. The pivot 46 is disposed inside the opening 48.

[0052] A first chamber 49a is formed between the recess 47 and the contact surface 45. The first chamber 49a is connected to the opening 48 and the opening 45a, and is formed to penetrate the locking portion 40. The first chamber 49a includes a guide surface 49d and a stopper surface 49e. The guide surface 49d and the stopper surface 49e are disposed closer to the first inclined surface 43 than the pivot 46. The guide surface 49d is curved so that one end portion is connected to the connecting portion between the first inclined surface 43 and the recess 47 and protrudes toward the connecting portion between the first inclined surface 43 and the contact surface 45. The stopper surface 49e protrudes from the other end portion of the guide surface 49d approximately parallel to the contact surface 45. A rib extending toward the opening 45a is formed on the protruding end portion of the stopper surface 49e. The guide surface 49d cooperates with the first upper support portion 6 or the first lower support portion 9 to guide the locking portion 40, and the stopper surface 49e restricts the movement of the locking portion 40.

[0053] A second chamber 49b is formed between the second inclined surface 44 and the contact surface 45. The second chamber 49b is formed at a corner where the second inclined surface 44 and the contact surface 45 intersect. The second upper support part 7 or the second lower support part 10 is inserted into the second chamber 49b. The second chamber 49b restricts the movement of the locking part 40. The second chamber 49b has a rib 49f perpendicular to the contact surface 45. The rib 49f protrudes from an end of the contact surface 45 (an end opposite to the part intersecting with the second inclined surface 44) toward the opening 48. The rib 49f is disposed on the second inclined surface 44 side of the pivot 46. A passage 49c is formed between the protruding end of the rib 49f and the pivot 46. The passage 49c connects the first chamber 49a and a part of the opening 48 on the second inclined surface 44 side. The upper bearing 5 or the lower bearing 8 is inserted into the passage 49c.

[0054] Fig. 16 is a partially enlarged right side view showing locking portion 40 in the first position, Fig. 17 is a partially enlarged right side view showing locking portion 40 in the second position, and Fig. 18 is a schematic cross-sectional view taken along line XVIII-XVIII in Fig. 16. Here, the locking portion 40 supported by the upper bearing 5, the first upper support portion 6, and the second upper support portion 7 will be described.

[0055] Pivot 46 of locking portion 40 is rotatably fitted inside upper bearing 5 with the left-right direction as the rotation axis direction. Rib 5a of upper bearing 5 is inserted into groove 46a of pivot 46. Diameter R (see FIG. 18) of pivot 46 is larger than dimension D (see FIG. 6). Diameter R is, for example, the diameter of a portion of pivot 46 where groove 46a is not formed. Therefore, pivot 46 is unlikely to slip out of the gap between upper bearing 5 and plate portion 4, and is unlikely to come off upper bearing 5.

[0056] When no document 50 is in contact with the contact surface 45 and no external force is acting, the locking portion 40 is in the first position, as shown in FIG. 16. The upper bearing 5 is inserted into the passage 49c from the opening 48 on the second inclined surface 44 side, and reaches the first chamber 49a. The second upper support portion 7 is inserted into the second chamber 49b. The shape of the second chamber 49b follows the shape of the second upper support portion 7. The second upper support portion 7 fits into the second chamber 49b and supports the locking portion 40. The first upper support portion 6 is positioned in the curved portion of the recess 47. In the first position, the locking portion 40 is supported by at least the upper bearing 5 and the second upper support portion 7.

[0057] When a document 50 comes into contact with the contact surface 45 and an external force acts on it, the posture of the locking portion 40 becomes the second posture as shown in FIG. 17. The locking portion 40 rotates clockwise from the first posture as viewed from the right side. The second upper support portion 7 comes out of the second chamber 49b. The locking portion 40 is guided by the first upper support portion 6 and the guide surface 49d. The movement of the locking portion 40 is restricted by the stopper surface 49e. In addition, the locking portion 40 is positioned in the left-right direction by the first side surface 41, the second side surface 42, and the first upper support portion 6, and moves in the positioned state. The first upper support portion 6 moves counterclockwise as viewed from the right side relative to the locking portion 40, and is disposed inside the first chamber 49a. The upper bearing 5 is inserted into the passage 49c from the opening 48 on the second inclined surface 44 side. The tip of the upper bearing 5 is disposed in the first chamber 49a. In the second position, the locking portion 40 is supported by at least the upper bearing 5 and the first upper support portion 6.

[0058] In the second position, contact surface 45 is oriented at a substantially right angle to bottom plate 2. Therefore, the contact area between contact surface 45 and the edge of document 50 tends to be large, making it easy to support document 50. The shape of the front side of the upper edge of plate portion 4 follows the curved portion of recess 47. Therefore, in the second position, recess 47 fits into the upper edge of plate portion 4, making it easy for contact surface 45 to maintain its position.

[0059] The case where the locking portion 40 is supported by the lower bearing 8, the first lower support portion 9, and the second lower support portion 10 is similar to the case where the locking portion 40 is supported by the upper bearing 5, the first upper support portion 6, and the second upper support portion 7, so a detailed description thereof will be omitted. A member extending left and right is provided in the vertical center of the plate portion 4, and the first lower support portion 9 protrudes forward from this member. The shape of the front side of the member follows the curved portion of the recess 47. Therefore, in the second position, the recess 47 fits into the member, and the contact surface 45 easily maintains its position.

[0060] 19 is a schematic perspective view of the document stand 1 supporting a document 50. When the contact surface 45 is pressed by the document 50, the locking portion 40 rotates. The user can push the document 50 in as the locking portion 40 rotates. Both sides of the document 50 are located on either side of the rotated locking portion 40, and are sandwiched and supported by the locking portion 40 that has not rotated. Therefore, even if there is no board or other document 50 next to the document 50, the document 50 can be locked in an upright position.

[0061] Fig. 20 is an explanatory right side view illustrating a state in which the first connecting portion 21 and the second connecting portion 31 of the first and second document stands 1 are connected. For example, when the first connecting portion 21 of the first document stand 1 and the second connecting portion 31 of the second document stand 1 are connected, as shown in Fig. 19, the second overhanging portion 33 is inserted into the upper guide groove 22 from the front side or the rear side, moves along the first inclined groove 22a, and is sandwiched between the first overhanging portion 23 and the bottom surface of the first inclined groove 22a. The second overhanging portion 35 is inserted into the lower guide groove 24 from the front side or the rear side, moves along the first inclined groove 24a, and is sandwiched between the first overhanging portion 25 and the bottom surface of the first inclined groove 24a.

[0062] Moreover, the first overhanging portion 23 is inserted into the upper guide groove 32 from the front or rear side, moves along the second inclined groove 32a, and is sandwiched between the second overhanging portion 33 and the bottom surface of the second inclined groove 32a. Moreover, the first overhanging portion 25 is inserted into the lower guide groove 34 from the front or rear side, moves along the second inclined groove 34a, and is sandwiched between the second overhanging portion 35 and the bottom surface of the second inclined groove 34a.

[0063] For example, when the right side of a first document stand 1 and the left side of a second document stand 1 are connected and the locking portion 40 at the right end of the first document stand 1 is pushed by a document 50 and rotated, the document 50 is clamped between the second locking portion 40 from the right end of the document stand 1 and the locking portion 40 at the left end of the second document stand 1. In the case of a single document stand 1, it is difficult to support the document 50 even if the locking portion 40 at the right or left end is pushed, since there is nothing to support one side of the document 50. By connecting multiple document stands 1, the locking portion 40 at the right or left end can be pushed at the connected portion to support the document 50.

[0064] The first connecting portion 21 or the second connecting portion 31 may be formed on the side of an article other than the document stand 1, such as a pen stand or a small item holder, to connect the document stand 1 to an article other than the document stand 1, or to connect articles other than the document stand 1 to each other. The first connecting portion 21 and the second connecting portion 31 can be formed on various articles.

[0065] Fig. 21 is a schematic perspective view of a document stand 1A with a partially modified configuration. The document stand 1 described above has a plurality of locking portions 40 lined up on the upper side and a plurality of locking portions 40 lined up on the lower side. That is, the locking portions 40 are arranged in two rows, one above the other, but as shown in the document stand 1A in Fig. 20, the locking portions 40 may be arranged in a single row. The locking portions 40 may be arranged in three or more rows. The vertical dimension of the plate portion 4A of the document stand 1A is shorter than that of the plate portion 4.

[0066] In the document stand 1 according to the embodiment, the locking portion 40 is supported at multiple points by providing the first upper support portion 6 and the second upper support portion 7, and the first lower support portion 9 and the second lower support portion 10. This makes it possible to prevent the locking portion 40 from being damaged due to stress being concentrated at one point.

[0067] In addition, the pivot 46 is unlikely to come out of the gap between the upper bearing 5 or the lower bearing 8 and the plate portion 4. In addition, for example, when multiple document stands 1 are used, the first connecting portion 21 of one document stand 1 and the second connecting portion 31 of the other document stand 1 can be connected and lined up.

[0068] Furthermore, for example, by inclining the first inclined grooves 22a, 24a and the second inclined grooves 32a, 34a so as to descend toward the rear, even if an external force acts on the connected first connecting portion 21 and second connecting portion 31, the first connecting portion 21 and the second connecting portion 31 are less likely to shift position in the front-rear and up-down directions. Furthermore, the first overhanging portions 23, 25 and the second overhanging portions 33, 35 can be inserted into the first inclined grooves 22a, 24a and the second inclined grooves 32a, 34a from both the front and rear directions. That is, they can be inserted from two directions.

[0069] Furthermore, by providing the locking portion 40 (first locking portion) on the upper side and the locking portion 40 (second locking portion) on the lower side, it is possible to easily lock the vertically long document 50. Furthermore, since the contact surface 45 is perpendicular to the bottom plate 2, the contact area between the contact surface 45 and the document 50 tends to be large, making it easier to support the document 50. In the above-described embodiment, the upper bearing 5 and the lower bearing 8 are provided on the plate portion 4, and the pivot 46 is provided on the locking portion 40, but the pivot may be provided on the plate portion 4, and the bearing may be provided on the locking portion 40. In this case, for example, two opposing support plates protrude forward from the plate portion 4, a pivot is provided between the protruding ends of the two support plates, a J-shaped bearing is provided between the first side surface 41 and the second side surface 42, and with the pivot inserted into the opening 48, the pivot and the bearing are rotatably connected.
