Description

[Technical field]

[0001] The present disclosure relates to a height adjustable display stand. [Background technology]

[0002] When displaying models such as architectural models, an exhibition stand is usually used. Since the height of the exhibition stand is fixed, in order to observe the size and characteristic parts of the model from an appropriate viewpoint, it is necessary to use multiple exhibition stands of different heights. It is also possible to use an exhibition stand with adjustable height. Although not related to a model exhibition stand, Patent Document 1 discloses a height-adjustable table in which a pair of legs intersecting in an X-shape provided on the underside of the top plate are formed of upper and lower members that are slidable in a nested manner, and the sliding between the upper and lower members is locked at a predetermined height adjustment position by a locking mechanism.

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 5-53528 Summary of the Invention [Problem to be solved by the invention]

[0004] Preparing multiple exhibition stands of different heights places a large burden on exhibitors and is not realistic. In addition, existing height-adjustable exhibition stands have complicated height adjustment mechanisms that can be seen by observers at the exhibition venue, giving the impression of clutter. For this reason, it is desirable for an exhibition stand for displaying models such as architectural models to be inconspicuous in itself, have a relatively simple structure that allows height adjustment, and can stably support the top plate. In addition, in order to reduce the burden of transporting and bringing them to the exhibition venue, it is preferable that they can be folded when not in use, be easy to carry, and be stacked for storage.

[0005] An object of the present disclosure is to provide an exhibition stand that can stably support a top plate with a relatively simple configuration and that allows the height of the top plate to be adjusted. [Means for solving the problem]

[0006] The present disclosure relates to a height-adjustable display stand including first and second legs intersecting in an X-shape, a top plate disposed on upper ends of the first and second legs, and a rotation restricting portion that restricts rotation about an intersection between the first and second legs, wherein the first leg includes a pair of first leg members disposed in parallel, the second leg includes a pair of second leg members disposed in parallel, one and the other of the pair of first leg members and one and the other of the pair of second leg members are respectively coupled to be rotatable about the intersection, and the rotation restricting portion extends between the pair of first leg members and restricts rotation of the pair of first leg members. a fixing member fixed to the first leg portion, a locking member extending between the pair of second leg members and locking to the pair of second leg members, and a connecting member connecting the fixing member and the locking member, wherein the pair of second leg members are each provided with a plurality of height adjustment locking holes, and the locking member has a pair of locking protrusions that lock into the plurality of height adjustment locking holes provided in the pair of second leg members, and the locking protrusions of the locking member are locked into any of the plurality of height adjustment locking holes of the second leg member, thereby restricting rotation of the first leg portion and the second leg portion, and the top plate can be adjusted to a predetermined height.

[0007] According to the present disclosure, the display stand includes a first leg and a second leg intersecting in an X-shape, a top plate, and a rotation restricting part that restricts rotation between the first leg and the second leg. The rotation restricting part includes a fixing member that extends between the pair of first leg members of the first leg, a locking member that extends between the pair of second leg members of the second leg, and a connecting member that connects the fixing member and the locking member. The locking projection of the locking member is locked into any one of a plurality of height-adjusting locking holes of the second leg member, thereby restricting rotation between the first leg and the second leg, and the top plate can be adjusted to a predetermined height. As a result, the top plate is supported by the pair of first leg members of the first leg and the pair of second leg members of the second leg, and therefore the top plate can be stably supported. The height of the tabletop can be adjusted by engaging the locking protrusion of the locking member connected to the fixing member by the connecting member with the height-adjustment locking hole of the second leg member, so that the height of the tabletop can be adjusted with a relatively simple configuration. Therefore, the tabletop can be stably supported and the height of the tabletop can be adjusted with a relatively simple configuration. In addition, since the first leg and the second leg rotate around the intersection, the tabletop can be folded, making it easy to carry and stackable for storage. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0010] FIG. 1 is a perspective view of an exhibition stand according to an embodiment of the present disclosure. The exhibition stand according to an embodiment of the present disclosure is a height-adjustable exhibition stand for displaying models such as architectural models as exhibits. As shown in FIG. 1, the exhibition stand 1 includes a first leg 10 and a second leg 20 intersecting in an X-shape, a top plate 30 disposed on the upper ends of the first leg 10 and the second leg 20, and a rotation restriction part 40 for restricting rotation about an intersection 2 between the first leg 10 and the second leg 20. The exhibition stand 1 is configured such that the lower ends of the first leg 10 and the second leg 20 are grounded, and an exhibit is placed on the top plate 30.

[0011] Fig. 2 is a front view of the display stand, Fig. 3 is a side view of the display stand, and Fig. 4 is a plan view of the display stand. Fig. 5 is a cross-sectional view of the display stand taken along line Y5-Y5 in Fig. 3, Fig. 6 is a cross-sectional view of the display stand taken along line Y6-Y6 in Fig. 3, and Fig. 7 is a cross-sectional view of the display stand taken along line Y7-Y7 in Fig. 3. In the following description, for convenience, the longitudinal direction along the surface of the top plate 30 is the left-right direction, the short side direction along the surface of the top plate 30 is the front-rear direction, and the thickness direction of the top plate 30 is the up-down direction, as shown in Fig. 1.

[0012] As shown in Fig. 1 to Fig. 3, the first leg 10 and the second leg 20 are connected to be rotatable about an intersection 2 that intersects in an X-shape when viewed from the front. The first leg 10 includes a pair of first leg members 11 arranged parallel to each other in the front-rear direction, and a first reinforcing member 12 fixed to the pair of first leg members 11 and extending in the front-rear direction between the pair of first leg members 11, which is a direction perpendicular to the pair of first leg members 11. The pair of first leg members 11 are formed in a quadrangular prism shape. The first reinforcing member 12 is formed in a cylindrical shape.

[0013] As shown in Fig. 5, a rectangular prism-shaped fixing recess 15 is formed on the lower surface 14 of the pair of first leg members 11 at the same height and extends in a direction perpendicular to the lower surface 14. A rectangular prism-shaped fixing protrusion 12a is formed on both ends of the first reinforcing member 12 and protrudes radially. The fixing protrusion 12a is press-fitted into the fixing recess 15 to fix the first reinforcing member 12 to the pair of first leg members 11. The upper surface 13 and the lower surface 14 of the first leg member 11 are surfaces that face upward and downward of the first leg member 11, respectively, when the first leg 10 and the second leg 20 are arranged in an X-shape.

[0014] 1 to 3, the second leg portion 20 includes a pair of second leg members 21 arranged parallel to each other in the front-rear direction, and a second reinforcing member 22 fixed to the pair of second leg members 21 and extending in the front-rear direction, which is a direction perpendicular to the pair of second leg members 21, across the pair of second leg members 21. The pair of second leg members 21 are formed in a rectangular prism shape. The second reinforcing member 22 is formed in a cylindrical shape.

[0015] As shown in Fig. 6, a rectangular prism-shaped fixing recess 25 is formed on the lower surface 24 of the pair of second leg members 21 at the same height so as to extend in a direction perpendicular to the lower surface 24. A rectangular prism-shaped fixing protrusion 22a is formed on both ends of the second reinforcing member 22 and protrudes radially. The second reinforcing member 22 is fixed to the pair of second leg members 21 by press-fitting the fixing protrusion 22a into the fixing recess 25. The upper surface 23 and the lower surface 24 of the second leg member 21 are surfaces that face upward and downward of the second leg member 21, respectively, when the first leg 10 and the second leg 20 are arranged in an X-shape.

[0016] The first reinforcing member 12 is fixed to a lower surface 14 of the first leg member 11 above the intersection 2 between the first leg portion 10 and the second leg portion 20, specifically, the intersection 2 between the first leg member 11 and the second leg member 21. The second reinforcing member 22 is fixed to a lower surface 24 of the second leg member 21 above the intersection 2 between the first leg portion 10 and the second leg portion 20, specifically, the intersection 2 between the first leg member 11 and the second leg member 21.

[0017] The first leg 10 and the second leg 20 are rotatably connected at an intersection 2 where they intersect in an X-shape by one (11a) and the other (11b) of a pair of first leg members 11 and one (21a) and the other (21b) of a pair of second leg members 21 being rotatably connected at intersections 2a, 2b, respectively, where the first leg members 10 and the second leg members 20 intersect in an X-shape.

[0018] 7, at the intersection 2a, a bolt insertion hole 26 is formed in one of the second leg members 21a, and a bolt accommodating hole 26a for accommodating the bolt head is also formed. An insert nut 17 is press-fitted into one of the first leg members 11a. The first leg member 11a and the second leg member 21a are rotatably coupled by screwing a bolt B1 into the insert nut 17 through the bolt insertion hole 26 until it contacts the bottom surface 17a.

[0019] At the intersecting portion 2b, a bolt insertion hole 16 is formed in the other first leg member 11b, and a bolt accommodating hole 16a for accommodating the bolt head is formed. An insert nut 27 is press-fitted into the other second leg member 21b. The first leg member 11b and the second leg member 21b are rotatably connected by screwing the bolt B1 through the bolt insertion hole 16 into the insert nut 27 until it contacts the bottom surface 27a.

[0020] The intersection 2a is formed so that the intersection 2b and the central axis C1 of the bolt B1 are coaxial. The bolt B1 extends from the inside to the outside of the first leg 10 and the second leg 20 in the front-rear direction and is arranged so as not to be exposed to the outside in the front-rear direction. As shown in FIG. 3, the pair of first leg members 11 and the pair of second leg members 21 are alternately arranged in a direction perpendicular to the extending direction of the pair of first leg members 11 and the pair of second leg members 21. One second leg member 21 is arranged between the pair of first leg members 11, and the other first leg member 11 is arranged between the pair of second leg members 21.

[0021] 1 to 3, the rotation restricting portion 40 includes a fixed member 41 extending between the pair of first leg members 11 in a direction perpendicular to the pair of first leg members 11 and fixed to the pair of first leg members 11, a locking member 42 extending between the pair of second leg members 21 in a direction perpendicular to the pair of second leg members 21 and locked to the pair of second leg members 21, and a connecting member 43 connecting the fixed member 41 and the locking member 42. The fixed member 41 and the locking member 42 are each formed in a cylindrical shape. The connecting member 43 is formed by a string.

[0022] 5, a rectangular prism-shaped fixing recess 18 is formed on the upper surface 13 of the pair of first leg members 11 at the same height below the intersection 2 so as to extend in a direction perpendicular to the upper surface 13. A rectangular prism-shaped fixing protrusion 41a protruding in the radial direction is formed on both ends of the fixing member 41. The fixing member 41 is fixed to the pair of first leg members 11 by pressing the fixing protrusion 41a into the fixing recess 18.

[0023] 6, a plurality of cylindrical height adjustment locking holes 28, specifically seven height adjustment locking holes 28, are formed on the upper surface 23 of the pair of second leg members 21 at the same height below the intersection 2 so as to extend in a direction perpendicular to the upper surface 23. The seven height adjustment locking holes 28 are first to seventh height adjustment locking holes 28a to 28g, which are spaced apart in order along the longitudinal direction of the second leg members 21 in a direction away from the intersection 2.

[0024] The locking member 42 has cylindrical locking projections 42a that protrude in the radial direction formed on both ends. The locking projections 42a are formed to have a diameter slightly smaller than the height adjustment locking holes 28 so as to be detachably locked in the height adjustment locking holes 28.

[0025] The connecting member 43 connects the fixed member 41 and the locking member 42, thereby restricting the rotation of the first leg 10 to which the fixed member 41 is fixed and the second leg 20 to which the locking member 42 is locked, about the intersection 2. The height of the tabletop 30 can be adjusted by restricting the angle between the first leg 10 and the second leg 20 according to the height adjustment locking hole 28 to which the locking protrusion 42a of the locking member 42 is locked. Specifically, as shown in FIG. 3, the string 43, which is the connecting member 43, extends along the central axis C2 perpendicular to the pair of first leg members 11 and the pair of second leg members 21 to connect the fixed member 41 and the locking member 42. As shown in FIG. 2, the fixed member 41 is formed with a through hole 41b extending in the diametric direction for passing one end of the string 43 through. The locking member 42 is formed with a through hole 42b extending in the diametric direction for passing the other end of the string 43 through. One end of the string 43 is passed through the through hole 41b of the fixing member 41 and then tied with a stopper knot, and the other end of the string 43 is passed through the through hole 42b of the locking member 42 and then tied with a stopper knot, connecting the fixing member 41 and the locking member 42.

[0026] The string 43, which is the connecting member 43, may be wound once around the outer periphery of the fixed member 41, crossed, and tied with a single knot in which the end of the one end is passed through the wound string, and the other end of the string may be wound once around the outer periphery of the locking member 42, crossed, and tied with a single knot in which the end of the other end is passed through the wound string, thereby connecting the fixed member 41 and the locking member 42. In this case, by finely adjusting the position of the knot, it is possible to make fine adjustments when a shape error occurs in the first leg 10 and the second leg 20. Specifically, as described later, when the display stand 1 is connected to another display stand 1', the heights of the adjacent display stands can be finely adjusted to eliminate any step.

[0027] In the display stand 1, when the lower ends of the first leg 10 and the second leg 20 are grounded and the locking protrusion 42a of the locking member 42 is locked in the fourth height adjustment locking hole 28d which is located in the center of the first to seventh height adjustment locking holes 28a to 28g, the fixing member 41 and the locking member 42 are positioned horizontally at the same height position, and the connecting member 43 is positioned horizontally.

[0028] In the display stand 1, the first leg 10 and the second leg 20 are connected by a connecting member 43 between a fixed member 41 and an engaging member 42, and when the fixed member 41 is fixed to the pair of first leg members 11, the engaging protrusion 42a of the engaging member 42 is engaged with one of a plurality of height-adjustment engaging holes 28 of the second leg member 21, thereby restricting the rotation of the first leg 10 and the second leg 20.

[0029] The top plate 30 is formed of a plate-like member having a rectangular shape in plan view, with the dimensions in the left-right direction being larger than those in the front-rear direction. Examples of the size of the top plate 30 include 600 mm in the front-rear direction, 1200 mm in the left-right direction, and a thickness of 24 mm. The bottom surface 32 of the top plate 30 is formed with a first groove portion 37 into which the upper end portion of the first leg portion 10 is fitted, as shown in FIG. 5, and a second groove portion 38 into which the upper end portion of the second leg portion 20 is fitted, as shown in FIG. 6. The bottom surface 32 of the top plate 30 is formed with a pair of first groove portions 37 recessed in the shape of a rectangular prism into which the upper ends of the pair of first leg members 11 are respectively fitted, as shown in FIG. 4, and a pair of second groove portions 38 recessed in the shape of a rectangular prism into which the upper ends of the pair of second leg members 21 are respectively fitted.

[0030] The width of the first groove 37 and the second groove 38 in the front-rear direction is slightly larger than the width of the first leg member 11 and the second leg member 21 in the front-rear direction, and the upper ends of the first leg member 11 and the second leg member 21 are detachably fitted into the first groove 37 and the second groove 38. The first groove 37 and the second groove 38 are formed longer in the left-right direction than in the front-rear direction so that the first leg member 11 and the second leg member 21 can be fitted into the first groove 37 and the second groove 38 regardless of which of the height adjustment locking holes 28 the locking member 42 is locked into. The pair of first grooves 37 and the pair of second grooves 38 are arranged point-symmetrically with respect to the center P1 of the tabletop 30 in a plan view.

[0031] As shown in Figures 5 and 6, the first leg member 11 and the second leg member 21 have corners 19a and 29a at their upper ends that are formed in an arc shape when viewed from the front, and corners 19b and 29b at their lower ends that are grounded are formed in an arc shape when viewed from the front.

[0032] The top plate 30 is removably disposed on the lower surface of the top plate 30 at the upper ends of the first leg portion 10 and the second leg portion 20 by fitting the upper ends of the first leg member 11 and the second leg member 21 into the first groove portion 37 and the second groove portion 38, respectively. The height of the top plate 30 can be adjusted to a predetermined height by engaging the locking projection 42a of the locking member 42 with any of a plurality of height adjustment locking holes 28 of the second leg member 21, thereby restricting the rotation of the first leg portion 10 and the second leg portion 20.

[0033] Fig. 8 is a front view of the display stand adjusted to another height. The display stand 1 shown in Fig. 1 shows a state in which the locking projection 42a of the locking member 42 is locked in the third height adjustment locking hole 28c, but for example, as shown in Fig. 8, the locking projection 42a of the locking member 42 can be locked in the fourth height adjustment locking hole 28d to adjust the top plate 30 to another height. For example, the height of the top plate 30 can be adjusted from 600 mm to 1200 mm.

[0034] When adjusting the tabletop 30 to a different height, the tabletop 30 is first removed, the intersecting angle between the first leg 10 and the second leg 20 is reduced so as to reduce the distance between the fixed member 41 and the locking member 42, the locking protrusion 42a of the locking member 42 is removed from the locking hole 28 for adjusting the specified height and moved from top to bottom into another locking hole 28 for adjusting the height, and then the intersecting angle between the first leg 10 and the second leg 20 is increased so as to increase the distance between the fixed member 41 and the locking member 42 to a distance at which the connecting member 43 does not bend, and the tabletop 30 is then lifted up again and the first groove portion 37 and the second groove portion 38 of the tabletop 30 are engaged with the upper ends of the first leg 10 and the second leg 20, respectively, to adjust to a different height.

[0035] As shown in FIG. 4, the top plate 30 has dowel holes 35 recessed cylindrically from the end faces 34 on both ends in the front-rear direction of the end faces 34 on both sides in the left-right direction. The dowel holes 35 are provided at the center of the top plate 30 in the up-down direction on the end faces 34. The dowel holes 35 provided on one end face 34 of the top plate 30 and the dowel holes 35 provided on the other end face 34 of the top plate 30 are disposed equidistant from the end face 33 in the front-rear direction of the top plate 30. The dowels 36 can be attached to the dowel holes 35 provided on both ends in the front-rear direction of the end faces 34 of the top plate 30. In FIG. 4, two dowel holes 35 are formed on each of the end faces 34 on both sides in the left-right direction of the top plate 30, and a dowel 36 is attached to one of the dowel holes 35. 4, the two dowel holes 35 provided in one end surface 34 of the top plate 30 and the two dowel holes 35 provided in the other end surface 34 of the top plate 30 are arranged symmetrically in a plan view. Note that two or more dowel holes may be provided in each of the end surfaces 34 on both left and right sides of the top plate 30.

[0036] Fig. 9 is a diagram showing the state in which the exhibition stands are connected. As shown in Fig. 9, the exhibition stand 1 can be connected to another exhibition stand 1' and arranged. By fitting the dowel hole and dowel provided on one end surface 34 of the top plate 30 of the exhibition stand 1 into the dowel and dowel hole provided on the other end surface 34 of the top plate 30 of the other exhibition stand 1', respectively, the two top plates 30 can be connected to connect the exhibition stand 1 and the exhibition stand 1'.

[0037] The dowel holes 35 provided on one end surface 34 of the top plate 30 and the dowel holes 35 provided on the other end surface 34 of the top plate 30 are arranged at equal distances from the end surface 33 in the front-rear direction of the top plate 30, so that a plurality of exhibition stands 1 can be connected by connecting another top plate 30 to either one end surface 34 or the other end surface 34 of the top plate 30 using a dowel 36. When connecting a plurality of exhibition stands 1, a pair of first leg members 11 and a pair of second leg members 21 are alternately arranged in the extension direction of the fixing member 41 perpendicular to the first leg member 11 and the second leg member 21, so that it is possible to prevent the first leg parts 10 and the second leg parts 20 of two adjacent exhibition stands 1 from colliding with each other. In addition, two or more dowel holes 35 may be provided on each of the end surfaces 33 on both sides in the front-rear direction of the top plate 30.

[0038] 1, in the unfolded state of the display stand 1, a first reinforcing member 12 is attached to the underside 14 above the intersection 2 of the first leg 10, and a fixing member 41 is attached to the upper side 13 below the intersection 2. A second reinforcing member 22 is attached to the underside 24 of the second leg 20 above the intersection 2, and a locking member 42 is disposed on the upper side 23 below the intersection 2.

[0039] The first leg member 11 and the second leg member 21 are formed in substantially the same shape when viewed from the front, except for the shape of the corners. The first reinforcing member 12 and the second reinforcing member 22, the fixing member 41 and the locking member 42 are formed in a cylindrical shape having the same diameter, and are formed in substantially the same shape when viewed from the front. The first reinforcing member 12 and the second reinforcing member 22 are disposed on the first leg member 11 and the second leg member 21 at the same distance from the intersection 2. The fixing member 41 and the locking member 42 are disposed on the first leg member 11 and the second leg member 21 at the same distance from the central axis C1 of the intersection 2 when the locking projection 42a is locked in the fourth height adjustment locking hole 28d.

[0040] Fig. 10 is a diagram showing a state in which two display stands 1 are folded and stored. When the first leg section 10 and the second leg section 20 are folded and stored, as shown in Fig. 10, the first leg section 10 and the second leg section 20 can be rotated so that the first leg member 11 and the second leg member 21 are overlapped when viewed from the front, and the first leg member 11 and the second leg member 21 can be folded by disposing them between the first reinforcing member 12 and the second reinforcing member 22 and between the fixing member 41 and the locking member 42.

[0041] 10, by arranging the first leg members 11 and second leg members 21 of multiple display stands 1 so that their left-right directions are in the opposite directions, the first leg portion 10 and the second leg portion 20 can be folded and stacked. Also, the top plates 30 of multiple display stands 1 can be stacked on the first leg portions 10 and second leg portions 20 of multiple display stands 1 for storage. Although FIG. 10 shows a case in which two display stands 1 are stored with the top plates stacked on top of the legs, it is also possible to store only the legs and only the top plates together.

[0042] Examples of materials for the top plate 30, the first leg 10, the second leg 20, the fixing member 41 and the locking member 42 of the rotation restriction part 40 of the display stand 1 include resin, metal, and laminated bamboo wood, and are preferably made of wood. For example, lauan plywood coated with clear urethane is used as the top plate 30, and for example, ash wood is used as the first leg 10, the second leg 20, the fixing member 41 and the locking member 42, the first reinforcing member 12, and the second reinforcing member 22. The string 43 as the connecting member 43 is preferably made of a material with little stretch, and from the viewpoint of strength, it is preferable to use a thin rope used for mountaineering equipment. Other materials may be used as the connecting member 43.

[0043] In the display stand 1, the first leg member 11 and the second leg member 21 are rotatably connected at the intersection 2 using a bolt B1 and an insert nut 27, but the first leg member and the second leg member may also be rotatably connected by other means, such as by providing a protruding pin on one of the first leg member 11 and the second leg member 21 and providing a pinhole on the other of the first leg member 11 and the second leg member 21 for rotatably receiving the protruding pin.

[0044] Thus, the display stand 1 according to this embodiment includes the first leg 10 and the second leg 20 intersecting in an X-shape, the top plate 30, and a rotation restricting section 40 that restricts the rotation of the first leg 10 and the second leg 20. The rotation restricting section 40 includes a fixing member 41 extending between the pair of first leg members 11 of the first leg 10, a locking member 42 extending between the pair of second leg members 21 of the second leg 20, and a connecting member 43 that connects the fixing member 41 and the locking member 42. The locking projection 42a of the locking member 42 is locked in any one of the multiple height-adjusting locking holes 28 of the second leg member 21, thereby restricting the rotation of the first leg 10 and the second leg 20, and the top plate 30 can be adjusted to a predetermined height.

[0045] As a result, the top plate 30 is supported by the pair of first leg members 11 of the first leg section 10 and the pair of second leg members 21 of the second leg section 20, so that the top plate 30 can be stably supported. The height of the top plate 30 can be adjusted by engaging the locking projection 42a of the locking member 42 connected to the fixing member 41 by the connecting member 43 with the height adjustment locking hole 28 of the second leg member 21, so that the height of the top plate 30 can be adjusted with a relatively simple configuration. Therefore, the top plate 30 can be stably supported and the height of the top plate 30 can be adjusted with a relatively simple configuration. In addition, since the first leg section 10 and the second leg section 20 rotate around the intersection 2, the top plate 30 can be folded, easily carried, and stored in layers.

[0046] Furthermore, the fixing member 41 is fixed to the first leg 10 below the intersection 2 between the first leg 10 and the second leg 20, and the locking member 42 is locked to the second leg 20 below the intersection 2 between the first leg 10 and the second leg 20. This makes it possible to move the locking member 42 to another height-adjustment locking hole 28 of the second leg 20 and lock it there.

[0047] Moreover, the height adjustment locking hole 28 is formed in the upper surface 23 of the second leg member 21. This allows the locking protrusion 42a of the locking member 42 to be locked in the height adjustment locking hole 28 of the second leg member 21 from above, making it relatively easy to adjust the height.

[0048] Furthermore, since the fixing member 41 is fixed to the upper surface 13 of the first leg member 11 and the locking member 42 is not fixed to either the first leg portion 10 or the second leg portion 20, the first leg member 11 and the second leg member 21 can be folded by stacking them together with the locking member 42 locked to the second leg member 21.

[0049] Moreover, the first leg 10 includes a first reinforcing member 12 extending between the pair of first leg members 11 and fixed to the pair of first leg members 11, and the second leg 20 includes a second reinforcing member 22 extending between the pair of second leg members 21 and fixed to the pair of second leg members 21. This allows the first leg 10 and the second leg 20 to be reinforced by the first reinforcing member 12 and the second reinforcing member 22.

[0050] Furthermore, the first reinforcing member 12 is fixed to the underside 14 of the first leg member 11 above the intersection 2 between the first leg portion 10 and the second leg portion 20, and the second reinforcing member 22 is fixed to the underside 24 of the second leg member 21 above the intersection 2 between the first leg portion 10 and the second leg portion 20. This allows the first leg member 11 and the second leg member 21 to be folded by overlapping them between the fixing member 41 and the second reinforcing member 22 and the locking member 42 and the first reinforcing member 12.

[0051] Further, the underside 32 of the tabletop 30 is provided with a first groove 37 into which the upper end of the first leg 10 is fitted, and a second groove 38 into which the upper end of the second leg 20 is fitted. This prevents the tabletop 30 from coming off the first leg 10 and the second leg 20, and allows the tabletop 30 to be stably supported by the first leg 10 and the second leg 20.

[0052] Furthermore, the top plate 30 has two or more dowel holes 35 recessed from the end faces 34 on both sides in a direction perpendicular to the extending direction of the fixing member 41, and the two or more dowel holes 35 provided in one end face 34 of the top plate 30 and the two or more dowel holes 35 provided in the other end face 34 of the top plate 30 are arranged symmetrically in a plan view. This makes it possible to relatively easily connect and arrange the top plates 30 of multiple display stands 1 using the two or more dowel holes 35 provided in one end face 34 and the other end face 34 of the top plate 30.

[0053] Moreover, the pair of first leg members 11 and the pair of second leg members 21 are arranged alternately in the extending direction of the fixing member 41. This makes it possible to prevent the first leg parts 10 and the second leg parts 20 of adjacent display stands 1 from colliding with each other when multiple display stands 1 are connected in a direction perpendicular to the extending direction of the fixing member 41.

[0054] Additionally, the top board 30, the first leg 10, the second leg 20, and the fixing member 41 and the locking member 42 of the rotation restricting portion 40 are made of wood. This allows for lighter weight and easier manufacturing than when they are made of metal. Furthermore, since the display stand 1 is made of wooden members with a natural color, it is possible to prevent the display stand 1 from standing out from exhibits such as architectural models.

[0055] Moreover, the connecting member 43 of the rotation restricting portion 40 is a string. As a result, the fixed member 41 and the locking member 42 are connected by the string 43, so that the height of the display stand 1 can be adjusted by relatively easily locking the locking protrusion 42a of the locking member 42 detachably to any one of the multiple height adjustment locking holes 28 of the second leg member 21 while maintaining a substantially constant separation distance between the fixed member 41 and the locking member 42.

[0056] The present disclosure is not limited to the exemplified embodiments, and various improvements and design modifications are possible without departing from the gist of the present disclosure.
