DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] An embodiment of the present invention will be described with reference to the drawings. In the following description, in a state where the display stand 10 is freestanding as shown in Fig. 1, the front direction of the display stand 10 (the horizontal direction in which the display surface faces) is referred to as "front", the opposite direction to the front is referred to as "rear", the up and down directions are respectively referred to as "up" and "down", and the left and right directions when the display surface of the display stand 10 is viewed from the front are respectively referred to as "left" and "right".

[0011] The foldable display stand 10 according to this embodiment is suitable for displaying a tire wheel 60, as shown in FIG. 4. In this embodiment, an example of displaying a tire wheel 60 will be described, but items other than the tire wheel 60 (such as tires) may be displayed. The display stand 10 can be unfolded as shown in FIG. 1 to be in a displayable state. In addition, the display stand 10 can be folded compactly as shown in FIG. 2, and is convenient to carry and store when folded. As shown in FIG. 1 and FIG. 3, the display stand 10 includes a support frame 11, legs 15, a grounding portion 30, an upper support piece 40, a lower support piece 45, and a leg opening and fixing portion 50. It is preferable that these parts are formed of a metal material (such as aluminum or stainless steel) that is resistant to corrosion and lightweight.

[0012] The support frame 11 is a frame body configured to be able to hold a tire wheel 60 along the front surface, as shown in Fig. 4. The support frame 11 according to this embodiment includes two vertical frames 12 on the left and right, and a horizontal member 13 installed between the two vertical frames 12.

[0013] The vertical frame 12 is a rectangular prism-shaped member. When the display stand 10 is made to stand on its own, the vertical frame 12 is used in a state in which the longitudinal direction is inclined with respect to the ground as shown in FIG. 1. The lower end surface of the vertical frame 12 is cut obliquely in accordance with the inclination of the vertical frame 12. That is, the lower end surface of the vertical frame 12 is a surface that is inclined with respect to the longitudinal direction, and is formed so as to be parallel to the ground when the display stand 10 is made to stand on its own. The lower end surface of the vertical frame 12 is adapted to abut against the upper surface of the bottom surface portion 31 of the grounding portion 30 in a state of use described later. In addition, the vicinity of the lower end of the vertical frame 12 is an attachment portion 20 for attaching the grounding portion 30 described later. The vertical frames 12 are provided in a pair on the left and right sides, and are provided with a first engagement portion 12a, a second engagement portion 12b, and a support piece receiving portion 12c on their inner surfaces facing each other.

[0014] The first engaging portion 12a and the second engaging portion 12b are protrusions for hooking the hook portion 52 of the leg opening fixing portion 50 described later. The first engaging portion 12a and the second engaging portion 12b according to this embodiment are pin-shaped portions protruding horizontally from the surface of the vertical frame 12. As will be described in detail later, as shown in FIG. 2, the support frame 11 and the leg portion 15 can be fixed in a closed state by hooking the hook portion 52 to the first engaging portion 12a. Also, as shown in FIG. 1, the support frame 11 and the leg portion 15 can be fixed in an open state by hooking the hook portion 52 to the second engaging portion 12b.

[0015] The support piece receiving portion 12c is a protrusion for supporting the lower support piece 45 described later in an open state. The support piece receiving portion 12c according to this embodiment is a pin-shaped portion protruding horizontally from the surface of the vertical frame 12. As will be described in detail later, when the lower support piece 45 is rotated forward, the lower surface of the lower support piece 45 abuts against the support piece receiving portion 12c. As a result, the support piece receiving portion 12c functions as a positioning portion when the lower support piece 45 is opened, and supports the load of the lower support piece 45. The support piece receiving portion 12c is provided for each lower support piece 45 so as to correspond one-to-one with the lower support piece 45. Since the display stand 10 according to this embodiment has six lower support pieces 45, six support piece receiving portions 12c are provided corresponding to the six lower support pieces 45. Note that the number of lower support pieces 45 increases or decreases depending on the number of items to be displayed, and the number of support piece receiving portions 12c also increases or decreases accordingly.

[0016] The horizontal members 13 are plate-shaped members that are installed horizontally between the vertical frames 12. The horizontal members 13 according to this embodiment are fixed to the rear surface of the vertical frames 12. The horizontal members 13 are provided in the same number as the number of tire wheels 60 that are held. The display stand 10 according to this embodiment is capable of holding three tire wheels 60, and therefore includes three horizontal members 13. An upper support piece 40, which will be described later, is attached to each horizontal member 13. In addition, a guide pin 13a for guiding the sliding of the upper support piece 40 is provided on each horizontal member 13. The head of this guide pin 13a engages with a slit 41a of the upper support piece 40, which will be described later. As a result, the upper support piece 40 is slidably attached to the horizontal members 13, and the upper support piece 40 can slide up and down along the longitudinal direction of the slit 41a. In addition, by providing this horizontal member 13, it is possible to suppress the wobbling of the vertical frame 12.

[0017] The leg 15 is a portion that is rotatably connected to the back surface of the support frame 11. The leg 15 is rotatably attached to the support frame 11 via a connection member 18 (such as a hinge or link) disposed at the upper end. By rotating the leg 15 relative to the support frame 11, the leg 15 and the support frame 11 can be opened in an inverted V-shape as viewed from the side as shown in Fig. 1, and the leg 15 and the support frame 11 can be closed in an I-shape as viewed from the side as shown in Fig. 2. The leg portion 15 according to this embodiment includes two vertical members 16 on the left and right and a reinforcing member 17 arranged between the two vertical members 16.

[0018] The vertical member 16 is a rectangular column-shaped member similar to the vertical frame 12 of the support frame 11. When the display stand 10 is made to stand on its own, the vertical member 16 is inclined so that its longitudinal direction is inclined with respect to the ground as shown in FIG. 1. The lower end surface of the vertical member 16 is cut obliquely in accordance with the inclination of the vertical member 16. That is, the lower end surface of the vertical member 16 is formed obliquely with respect to the longitudinal direction, and is formed so as to be parallel to the ground when the display stand 10 is made to stand on its own. The lower end surface of the vertical member 16 is adapted to abut against the upper surface of the bottom surface portion 31 of the ground contact portion 30 in a usage state described later. The vicinity of the lower end of the vertical member 16 serves as an attachment portion 20 for attaching the ground contact portion 30 described later.

[0019] The reinforcing member 17 is a plate-like member that is horizontally installed between the vertical members 16. The reinforcing member 17 according to this embodiment is fixed to the rear surface of the vertical member 16. By providing this reinforcing member 17, it is possible to suppress wobbling of the vertical member 16.

[0020] The grounding portion 30 is a portion that is grounded when the display stand 10 is made to stand on its own. The grounding portion 30 is provided rotatably with respect to the mounting portion 20 provided at the lower end of the support frame 11 and the leg portion 15. The display stand 10 according to this embodiment has a total of four mounting portions 20 at the lower ends of the two vertical frames 12 and the lower ends of the two vertical members 16, and therefore has a total of four grounding portions 30 provided at the mounting portions 20. By rotating the grounding portion 30 with respect to the mounting portions 20, it is possible to switch between a usage state in which the display stand 10 is grounded substantially horizontally on the ground as shown in FIG. 1 and FIG. 7(b) and a folded state in which the display stand 10 is folded to a state substantially parallel to the support frame 11 and the leg portion 15 as shown in FIG. 2 and FIG. 6(a). The grounding portion 30 according to this embodiment has a shape in which a plate material is bent into a generally U-shaped cross section, and includes a bottom surface portion 31, a first standing portion 32, and a second standing portion .

[0021] The bottom surface portion 31 is a flat plate-like portion. The surface of the bottom surface portion 31 (the lower surface when in use) is the surface that comes into contact with the ground. As shown in FIG. 2, this surface is provided with an anti-slip portion 37 made of rubber, resin, or the like. Providing this anti-slip portion 37 increases the stability of the display stand 10 when it is standing on its own. Note that the bottom surface portion 31 may be directly in contact with the ground without providing the anti-slip portion 37.

[0022] The first upright portion 32 is a flat plate-like portion extending from one end of the bottom portion 31 when viewed in the short direction. The first upright portion 32 is continuous with the end of the bottom portion 31 so as to form an obtuse angle with the bottom portion 31. The inclination angle of the first upright portion 32 with respect to the bottom portion 31 is set to be equal to the inclination angle of the support frame 11 (vertical frame 12) or the leg portion 15 (vertical member 16) with respect to the ground when the display stand 10 is freestanding.

[0023] The second upright portion 35 is a flat plate-like portion extending from the other end (the end opposite to where the first upright portion 32 is provided) of the bottom surface portion 31 when viewed in the short direction. The second upright portion 35 is continuous with the end of the bottom surface portion 31 so as to form an acute angle with the bottom surface portion 31. The second upright portion 35 is provided parallel to the first upright portion 32.

[0024] The grounding part 30 has a distorted U-shape in side view due to the above-mentioned configuration. The opening of this U-shape opens upward in the use state, that is, the intermediate groove part 36 opens between the first standing part 32 and the second standing part 35. The mounting part 20 is formed with a width slightly smaller than the intermediate groove part 36, and is attached to the grounding part 30 in a state where it is inserted into the intermediate groove part 36. At this time, the inner surface of the first standing part 32 faces the surface (front or rear surface) of the mounting part 20. Therefore, when the grounding part 30 is rotated, the inner surface of the first standing part 32 and the surface of the mounting part 20 play the role of a guide surface (sliding surface), and the grounding part 30 can be rotated smoothly.

[0025] Meanwhile, as shown in Fig. 5, two guide grooves (first guide groove 33, second guide groove 34) are formed in first standing portion 32. These guide grooves are provided to respectively accommodate two pin members (first pin member 21, second pin member 22) provided in mounting portion 20 and to guide the rotation of ground contact portion 30. In other words, ground contact portion 30 is configured to rotate as the two guide grooves move along the two pin members.

[0026] Two pin members (first pin member 21, second pin member 22) are provided so as to protrude from the surface of the mounting portion 20 facing the first standing portion 32. In this embodiment, as shown in FIG. 10(a), the pin members are fixed to the vertical frame 12 via a spacer 25 so as to protrude from the surface of the mounting portion 20. The spacer 25 is a cylindrical member through which the pin members can be inserted, and one end face of the spacer 25 abuts against the surface of the mounting portion 20, and the other end face of the spacer 25 abuts against the head 23 of the pin member. The spacer 25 through which the pin members are inserted penetrates the guide groove of the grounding portion 30, so that the guide groove moves on the spacer 25. The axial length of the spacer 25 is set to be larger than the plate thickness of the first standing portion 32 of the grounding portion 30, so that the head 23 of the pin member does not press the first standing portion 32 against the mounting portion 20, and a play is formed for rotating the grounding portion 30. The diameter of the head 23 of the pin member is set larger than the guide groove so that the pin member does not come off the guide groove. As shown in FIG. 5, the two pin members are arranged such that the second pin member 22 is disposed directly below the first pin member 21.

[0027] In addition, the pin members are not limited to those described above, and one or both of the pin members may have fastening means. That is, as shown in FIG. 10(b), a first pin member 21 equipped with a handle 24 and capable of fastening may be used. If such a pin member is used, the pin member can be fastened by rotating the handle 24, so that the first standing portion 32 of the ground contact portion 30 can be fixed so as not to move, and the ground contact portion 30 can be reliably held when in use or folded. In addition, the second pin member 22 may have fastening means instead of the first pin member 21, or both the first pin member 21 and the second pin member 22 may have fastening means. In the example shown in FIG. 10(b), the spacer 25 is not attached to the pin member capable of fastening, but the spacer 25 may be attached.

[0028] The first guide groove 33 is for guiding the movement of the first pin member 21. The first guide groove 33 according to this embodiment is an irregular long hole, and is formed in a substantially L-shape. Specifically, the first guide groove 33 according to this embodiment is a shape that combines a first parallel portion 33a extending in the vertical direction and a second parallel portion 33b extending in the horizontal direction from the upper end of the first parallel portion 33a. In addition, a corner portion 33c where the first parallel portion 33a and the second parallel portion 33b are connected is R-shaped, and when the grounding portion 30 rotates, the first pin member 21 engaged with this corner portion 33c becomes a rotation fulcrum.

[0029] The second guide groove 34 is for guiding the movement of the second pin member 22. The second guide groove 34 according to this embodiment is an irregular long hole, and has a shape that combines straight lines and curved lines. Specifically, the second guide groove 34 according to this embodiment has a shape that combines a first parallel portion 34a that extends in a substantially vertical direction, a 1 / 4 arc-shaped arc portion 34c that extends upward from the upper end of the first parallel portion 34a, and a second parallel portion 34b that extends in a horizontal direction from the upper end of the arc portion 34c. The arc portion 34c is a section through which the second pin member 22 moves when the ground contact portion 30 rotates. The center of the arc portion 34c is formed to be the same as the center of the R-shape of the corner portion 33c.

[0030] The first parallel portion 33a of the first guide groove 33 and the first parallel portion 34a of the second guide groove 34 are formed almost parallel to each other. The second parallel portion 33b of the first guide groove 33 and the second parallel portion 34b of the second guide groove 34 are formed almost parallel to each other. The term "almost parallel to each other" means that the two guide grooves are parallel to the extent that they can move in the same direction along the two pin members. That is, the two guide grooves may be completely parallel, or may be inclined within a range that does not exceed the clearance width between the pin members and the guide grooves. In this embodiment, the first parallel portion 34a of the second guide groove 34 is formed with a slight inclination, and therefore the first parallel portion 33a of the first guide groove 33 and the first parallel portion 34a of the second guide groove 34 are not strictly parallel. The purpose of this configuration is to prevent the freestanding display stand 10 from "wobbling". That is, by slightly inclining the first parallel portion 34a of the second guide groove 34, the clearance width is made different between the left and right sides of the second pin member 22 when the leg 15 is deployed as shown in FIG. 5. In the example of FIG. 5, the clearance is small (or there is no clearance) on the left side of the second pin member 22, so that the "wobble" that moves the leg 15 to the right can be suppressed. In addition, the opposite leg 15 that is paired with this leg 15 is configured symmetrically to this leg 15, so that the "wobble" in the opposite direction (the "wobble" that moves the leg 15 to the left in FIG. 5) can be suppressed, and the pair of legs suppresses the "wobble" to the left and right. In this way, the "wobble" may be suppressed by providing a slight angle to the two parallel portions. The procedure for rotating the ground contact portion 30 using this pin member and guide groove is as follows.

[0031] As shown in FIG. 6(a), in the folded state, the first pin member 21 is engaged with the second parallel portion 33b of the first guide groove 33, and the second pin member 22 is engaged with the second parallel portion 34b of the second guide groove 34. At this time, when the support frame 11 and the leg portion 15 are folded and the lower end of the vertical frame 12 of the support frame 11 or the vertical member 16 of the leg portion 15 is placed vertically on the ground, the ground contact portion 30 is suspended in the air, and the pin member is engaged with the back (upper end) of the second parallel portion 33b, 34b due to the weight of the ground contact portion 30. In this way, the two pin members are accommodated in the second parallel portions 33b, 34b that are parallel to each other and provided at the ends of the two guide grooves, so that the ground contact portion 30 can maintain the folded state. Therefore, it is convenient because the ground contact portion 30 does not open when carrying it.

[0032] When it is desired to rotate the ground contact portion 30 from this state, as shown in Fig. 6(b), the ground contact portion 30 is lifted upward so that the two pin members are disposed at the exits (lower ends) of the second parallel portions 33b, 34b. Thereafter, as shown in Fig. 7(a), when the ground contact portion 30 is rotated around the first pin member 21 engaged with the corner portion 33c as a rotation fulcrum, the arc portion 34c of the second guide groove 34 moves along the second pin member 22. At this time, in order to rotate the ground contact portion 30 to below the mounting portion 20, it is necessary to lift the support frame 11 and the legs 15 slightly.

[0033] Finally, as shown in Fig. 7(b), when the support frame 11 and the legs 15 are lowered, the first pin member 21 engages with the first parallel portion 33a of the first guide groove 33, and the second pin member 22 engages with the first parallel portion 34a of the second guide groove 34. In this way, the two pin members are accommodated in the first parallel portions 33a, 34a that are parallel to each other and provided at the ends of the two guide grooves, so that the grounding portion 30 can be maintained in a usable state. Therefore, when the display stand 10 is made to stand on its own, the grounding portion 30 can be opened and used without any rattling.

[0034] Furthermore, in the state shown in Figure 7 (b), if the lower end of the mounting portion 20 (vertical frame 12 or vertical member 16) is placed on the bottom surface portion 31 of the ground contact portion 30, the free-standing state of the display stand 10 can be further stabilized.

[0035] Conversely, when it is desired to rotate the ground contact portion 30 to fold it, the procedure described above can be carried out in reverse. That is, the attachment portion 20 (support frame 11 and leg portion 15) is lifted slightly, the ground contact portion 30 is rotated in the closing direction, and the ground contact portion 30 is lowered so that the two pin members engage with the second parallel portions 33b and 34b.

[0036] In this way, by providing the first parallel parts 33a, 34a and the second parallel parts 33b, 34b, it is possible to stabilize the use state or the folded state of the ground contact part 30. This makes it possible to prevent rattling during use, and also prevents the ground contact part 30 from rotating unintentionally, allowing for safe use.

[0037] In this embodiment, the mounting portion 20 is provided with a pin member, and the grounding portion 30 is formed with a guide groove, but this may be reversed. That is, the mounting portion 20 may be formed with a guide groove, and the pin member may be provided in the grounding portion 30.

[0038] The upper support piece 40 is for holding the upper part of an exhibit such as a tire wheel 60. As shown in FIG. 1, the upper support piece 40 according to this embodiment includes a front plate portion 41 and side plate portions 42 bent backward from both sides of the front plate portion 41.

[0039] The front plate 41 is a portion that is attached along the rear surface of the cross member 13. A slit 41a is formed in the front plate 41 in the up-down direction. A guide pin 13a attached to the cross member 13 is engaged with the slit 41a. By engaging the guide pin 13a with the slit 41a, the upper support piece 40 is attached so as not to fall off the cross member 13, and is movable along the longitudinal direction of the slit 41a. A screw member (not shown) can be attached from the rear side of the front plate 41. The screw member passes through the slit 41a and is screwed into the cross member 13. By fastening the screw member, the upper support piece 40 that has been slid to an arbitrary position can be fixed at that position.

[0040] A holding piece 41b protruding forward is provided on the upper end of the front plate portion 41. The front end of this holding piece 41b is bent downward in a substantially L-shape, so that the upper end of the tire wheel 60 can be held, as shown in FIG.

[0041] When displaying the tire wheel 60 on the display stand 10, the upper support piece 40 can be slid upward as shown in Fig. 8(b), making the work easy. Then, after placing the tire wheel 60 on the lower support piece 45 described below, the position of the upper support piece 40 is adjusted to match the size of the tire wheel 60, and the tire wheel 60 is pressed down by the holding piece 41b as shown in Fig. 8(a).

[0042] The lower support piece 45 is for placing display items such as tire wheels 60. The lower support piece 45 according to this embodiment is a plate-shaped part attached to the inner surface of the vertical frame 12. The lower support pieces 45 are attached to the left and right vertical frames 12, respectively, and are arranged at the same height as a pair on the left and right. In this embodiment, three pairs (six in total) of lower support pieces 45 are provided. The lower support piece 45 according to this embodiment includes a pivot connection portion 46 and an arm portion 47, as shown in FIG. 9.

[0043] The pivotal connection part 46 is a part that is fixed to the inner surface of the vertical frame 12. This pivotal connection part 46 is attached to the vertical frame 12 by a pivot pin 46a and is capable of pivoting about the pivot pin 46a.

[0044] The arm portion 47 is a portion extending from the pivot connection portion 46. The tip of the arm portion 47 forms a holding portion 48 that is bent into a substantial J-shape in side view. The holding portion 48 is covered with a covering portion 49 made of rubber, resin, or the like. By providing the covering portion 49, it is possible to obtain the effects of preventing slipping and scratches.

[0045] When the tire wheel 60 is to be held by this lower support piece 45, as shown in Fig. 9(a), the arm portion 47 is rotated forward until the lower end of the arm portion 47 abuts against the support piece receiving portion 12c. This causes the holding portion 48 to protrude forward from the vertical frame 12. The tire wheel 60 can be placed on this protruding holding portion 48.

[0046] When the lower support piece 45 is not in use, the arm portion 47 is rotated upward as shown in Fig. 9(b). As a result, the lower support piece 45 is rotated backward to a position where it does not protrude forward from the vertical frame 12, so that it does not get in the way.

[0047] The leg-opening fixing part 50 is a rod-shaped member for fixing the opening angle between the support frame 11 and the leg 15. The leg-opening fixing part 50 is attached to each of the left and right vertical members 16 constituting the leg 15. A rotation support part 51 is provided at one end of the leg-opening fixing part 50, and a hook part 52 is provided at the other end. The rotation support part 51 is a part that is rotatably fixed to the leg 15, and the leg-opening fixing part 50 is freely rotatable around the rotation support part 51. The hook part 52 is a part that engages with the support frame 11. As already described, the support frame 11 (vertical frame 12) has a first engagement part 12a and a second engagement part 12b to which the hook part 52 can be hooked.

[0048] Of these, the first engagement portion 12a is for fixing the support frame 11 and the legs 15 in a closed state, as shown in Fig. 2. When the support frame 11 and the legs 15 are in a closed state and the hook portion 52 is hooked onto the first engagement portion 12a, the support frame 11 and the legs 15 can be locked so that they do not open.

[0049] 1, the second engagement portion 12b is for fixing the support frame 11 and the legs 15 in an open state. When the support frame 11 and the legs 15 are opened in an inverted V shape and the hook portion 52 is hooked onto the second engagement portion 12b, the support frame 11 and the legs 15 can be fixed at a predetermined open angle.

[0050] Furthermore, the hook portion 52 hooked onto the first engagement portion 12a or the second engagement portion 12b cannot be removed unless it is operated upward, so it is not easily removed even if a force is applied to close (or open) the support frame 11 or the legs 15.

[0051] As described above, according to this embodiment, the ground contact portion 30 is rotatably provided at the lower end of the support frame 11 and the legs 15. This ground contact portion 30 can be switched between a usage state in which it is in contact with the ground substantially horizontally and a folded state in which it is folded up to a state parallel to the support frame 11 and the legs 15. With this configuration, in the usage state, the ground contact portion 30 can stably stand on its own. In addition, in the folded state, the ground contact portion 30 can be folded up to a state parallel to the support frame 11 and the legs 15, so that the ground contact portion 30 does not protrude to the left or right, and the width can be folded compactly.

[0052] In addition, since the vertical frame 12 constituting the support frame 11 is a single column-shaped member that is continuous in the longitudinal direction, the number of parts and the weight can be minimized. This makes it possible to provide a display stand that can be manufactured inexpensively and is easy to carry.

[0053] In addition, the tire wheel 60 is provided with an upper support piece 40 capable of holding an upper portion thereof, and the upper support piece 40 is attached to the support frame 11 so as to be slidable up and down. This makes it possible to hold tire wheels 60 of different diameters. Furthermore, the holding force can be increased by adjusting the position of the upper support piece 40.

[0054] The tire wheel 60 can be placed on the lower support piece 45, which is attached to each of the left and right vertical frames 12 constituting the support frame 11 and can be rotated backward to a position where it does not protrude forward from the vertical frames 12. This configuration makes it possible to prevent unintentional contact with or getting caught on the unused lower support piece 45. Also, by rotating the lower support piece 45 backward when carrying the tire wheel 60, it is possible to prevent injury.

[0055] The support frame 11 also includes a leg opening fixing part 50 for fixing the opening angle between the support frame 11 and the legs 15. One end of the leg opening fixing part 50 is rotatably fixed to the legs 15, and the other end of the leg opening fixing part 50 includes a hook part 52 that engages with the support frame 11. The support frame 11 includes a first engagement part 12a and a second engagement part 12b on which the hook part 52 can be hooked. The support frame 11 and the legs 15 can be fixed in a closed state by hooking the hook part 52 to the first engagement part 12a, and the support frame 11 and the legs 15 can be fixed in an open state by hooking the hook part 52 to the second engagement part 12b. This prevents the legs 15 from opening or closing unintentionally, allowing for safe use.

[0056] The support frame 11 and the leg 15 are provided with an attachment portion 20 for attaching the grounding portion 30, and one of the attachment portion 20 and the grounding portion 30 is provided with two pin members, and the other is formed with two guide grooves for accommodating the two pin members. The grounding portion 30 is configured to rotate as the two guide grooves move along the two pin members, and first parallel portions 33a and 34a are provided at the ends of the two guide grooves, and the grounding portion 30 is held in a usable state by accommodating the two pin members in the first parallel portions 33a and 34a. According to this configuration, the grounding portion 30 in a usable state is fixed by the two pin members, so that the grounding portion 30 can be stabilized when the display stand 10 is made to stand on its own.

[0057] Further, second parallel portions 33b, 34b parallel to each other are provided at the ends of the two guide grooves opposite to the first parallel portions 33a, 34a, and two pin members are housed in the second parallel portions 33b, 34b, thereby holding the ground contact portion 30 in the folded state. With this configuration, the ground contact portion 30 in the folded state is fixed by the two pin members, so that it is possible to prevent the ground contact portion 30 from opening unintentionally when stored or carried.

[0058] In addition, if the grounding part 30 is fixed by the pin member and the guide groove as described above, no tools are required to open and close the grounding part 30, which is convenient to use. In addition, there is no risk of parts being installed incorrectly, and there is no risk of parts being lost. [Explanation of symbols]
