Description

[Technical Field]

[0001] The present invention relates to a food stall that can be easily and quickly assembled and disassembled by one person. [Background technology]

[0002] In recent years, events such as flea markets, marches, garage sales, bazaars, and junk markets have become more frequent. People of all ages and genders participate in these events as exhibitors. At these events, stalls are often used to sell products to visitors. These stalls are equipped to display and sell food, small items, and other items.

[0003] The floats used in the events mentioned above are basically of very simple structure, consisting only of a top board and a sunshade awning, with poles to support them. Furthermore, the floats can be easily assembled and disassembled, and can be stored as is or transported to another event venue. Participants in the event often own such floats, or the organizers often lend them to participants. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2022-13085 [Patent Document 2] Patent No. 7396753 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0005] A simple stall is known from Patent Document 1 (JP Patent Publication No. 2022-13085A). Patent Document 1 describes a prefabricated stall in which a set of roof members are detachably arranged between a set of supports arranged opposite each other at a distance. The supports have a set of support posts connected to each other so that they can rotate freely left and right via a pivoting part provided at the top end. The set of support posts are assembled into a roof shape using connectors.

[0006] In other words, the support is assembled using two supports and connectors, but the two supports and connectors are separate components, and assembling them takes time and requires fasteners and tools such as bolts and nuts. In addition, shelves and coverings must be assembled, and assembling by one participant takes a considerable amount of time and effort.

[0007] Patent Document 2 (Patent Publication No. 7396753) is not a stall but a tent, but the pipe frames that make up the framework are configured in an X-shape. X-shaped supports are suitable for supporting stalls, but in Patent Document 2, the two pipe frames that make up the X-shaped framework can be folded by means of a pin that forms the intersection.

[0008] However, when two pipe frames are assembled in an X-shape, a link-like connecting member is required to maintain this state. Moreover, such pipe frames are made of metal. In other words, applying Patent Document 2 to a stall may result in high costs. Furthermore, in situations where stalls assembled almost entirely from wood are preferred, Patent Document 2, which includes metal members, is inappropriate.

[0009] Next, although there are no specific patent documents, there are conventional stalls that use a frame in which two square pillars a, a for supporting the top plate and awning are expanded in an X shape by a pivotal connection part b made of bolts and nuts, as shown in the conventional product in Figure 7.

[0010] This type of product consists of two long rectangular pillars of the same size and shape that form an X shape when in use and a straight line when folded. The pivotal joint b that forms the X shape uses bolts and nuts. Because of this configuration, when the two rectangular pillars a, a are expanded into an X shape via the pivotal joint b, they cannot be secured together to maintain the X shape unless the bolts and nuts of the pivotal joint b are tightened.

[0011] However, simply tightening the bolts and nuts at the pivot joint b does not create a stable X-shape, and pin material e is used to attach the top plate d to the through hole c formed in the square pillars a and a. The square pillars a, a are fixed in an X-shape only when the bolts are passed through the through-holes c. Therefore, assembling a stall using conventional products is difficult. Furthermore, assembling a stall with conventional products requires the use of bolts and nuts, which also requires tools such as screwdrivers and wrenches.

[0012] However, as mentioned above, even the simplest floats are made up of pillars, frames, a top board, and a tent, and assembling one requires at least two people. Therefore, if there is only one participant, it is often necessary to ask for help from other participants.

[0013] However, exhibitors are often busy and do not have time to help others, so they end up assembling and disassembling by themselves. For this reason, it is preferable for a stall to have an extremely simple structure and be extremely easy to assemble and disassemble in a short time, but the above-mentioned Patent Documents 1 and 2 and the conventional products are not suitable. Therefore, the object of the present invention is to provide a stall that is extremely simple in structure and can be easily and quickly assembled and disassembled by one person. [Means for solving the problem]

[0014] Therefore, the inventors have conducted extensive research to solve the above problems, and as a result, have found that the invention of claim 1 is a structure comprising a long, large-width rectangular pillar and a small-width rectangular pillar of the same length as the large-width rectangular pillar, the large-width rectangular pillar and the small-width rectangular pillar being overlapped with each other along the width direction so as to form an L-shaped cross section, and the large-width rectangular pillar and the small-width rectangular pillar are pivotally connected at their longitudinal intermediate points to form a pivotal support, and the large-width rectangular pillar and the small-width rectangular pillar are configured in an X-shape by intersecting with each other at an angle θ of 60 to 70 degrees, which is less than 90 degrees, from a straight line state, and in this X-shape, the large-width rectangular pillar and the small-width rectangular pillar are intersecting with each other at an angle θ of 60 to 70 degrees, which is less than 90 degrees. The above problem was solved by providing a stall characterized in that the square pillars and the vertical X pillars are fixed by inserting fixing devices into fixing holes provided near the pivot points, two vertical X pillars fixed in the X shape are provided facing each other with the narrow square pillar on the inside at a specified distance, a lower connecting rod is attached between the narrow square pillars and near the lower ends, and an upper connecting rod is attached near the upper ends, an awning is stretched between the upper ends of the vertical X pillars, and a top plate body is attached to both vertical X pillars below the pivot points.

[0015] The above problem was solved by the invention of claim 2, which is the stall described in claim 1, characterized in that the vertical X-shaped pillar is expanded into a predetermined X-shape, the fixing holes of the wide rectangular pillar and the fixing holes of the narrow rectangular pillar are each formed so that their distances from the pivot part are the same, and the axial fixing devices that pass through both fixing holes are inserted to fix the vertical X-shaped pillar.

[0016] The above problem is solved by the invention of claim 3, which is a stall described in claim 1 or 2, characterized in that the large and small rectangular pillars of the vertical X-shaped pillar body each have a long side along the width direction and a short side along the thickness direction when viewed in cross section, and the short sides of the large and small rectangular pillars are of equal dimensions, and the long side of the large rectangular pillar is larger than the long side of the small rectangular pillar, approximately twice as large.

[0017] The above problem is solved by the invention of claim 4, which is the stall described in claim 3, characterized in that the fixing holes are set lower than the pivot points. The above problem is solved by the invention of claim 5, which is the stall described in claim 1 or 2, characterized in that the lower connecting rod and the upper connecting rod are attached to the narrow square pillars by mounting screws with hand-turnable knobs on the screw shafts. The above problem is solved by the invention of claim 6, which is the stall described in claim 1 or 2, characterized in that rear curtains are provided at the rear upper ends of both of the upright X-pillars. [Effects of the Invention]

[0018] In the invention of claim 1, when the vertical X-pillar is placed horizontally, the large and small rectangular pillars are pivotally connected to each other at the pivot point, expanding into an X shape. This X-shape can then be maintained by a fixture. This allows the vertical X-pillar to be fixed at two points by the pivot point and the fixture. Furthermore, by attaching only the lower and upper connecting rods between a pair of vertical X-pillars, the two vertical X-pillars can maintain their X-shape. Furthermore, when assembling the two vertical X-pillars, the lower connecting rod connects the two small rectangular pillars to the lower ends and the upper connecting rod connect them to the upper ends. This allows the two small rectangular pillars to form a roughly rectangular frame, preventing the pillars from coming apart, allowing the stall to be assembled in a very stable manner.

[0019] The vertical X-pillar body can be placed horizontally and an awning or the like can be attached, allowing the stall to be assembled almost completely in a horizontal position. The top plate body can be attached by inverting the vertical X-pillar body and standing it up, allowing one person to complete the assembly of the stall extremely easily and in a short time. In some cases, the top plate body can also be assembled in a horizontal position.

[0020] For the reasons mentioned above, while multiple people were required as in the past, the stall of the present invention can be assembled and disassembled (dismantled) by one person by fixing the vertical X-pillar body in an X-shape in a horizontal position, and attaching the awning and the top plate body after inverting it.

[0021] The vertical X-shaped pillar is composed of a large rectangular pillar and a small rectangular pillar, and the use of the large rectangular pillar in particular improves the overall strength of the large rectangular pillar when the large rectangular pillar and the small rectangular pillar are expanded to form an X-shape. Furthermore, when the large rectangular pillar and the small rectangular pillar are folded in a straight line, the cross section perpendicular to the longitudinal direction is L-shaped, and by combining two vertical X-shaped pillars with the small rectangular pillars facing each other, one with an L-shaped cross section and the other with an inverted L-shaped cross section, it can be stored compactly, which has the advantage of being easy to carry.

[0022] As described above, the present invention allows the awning and top plate to be attached to the vertical X-pillar while maintaining the X-shaped position of the vertical X-pillar in the horizontal position. In other words, in the past, assembling a stall with supports that could be expanded into an X shape required at least two people, with one person holding the X-shaped support while the other attached the awning and top plate. However, with the present invention, the vertical X-pillar can be fixed in the X-shaped position in the horizontal position. Therefore, the awning can be attached to the vertical X-pillar at a low position due to the horizontal position, and the top plate can also be attached. The greatest advantage of the present invention is that these tasks can be performed by one person.

[0023] In the invention of claim 2, the fixing structure for maintaining the vertically placed X-shaped column can be constructed simply by fixing holes in the large-width square column, fixing holes in the small-width square column, and axial fixing devices inserted into both fixing holes, resulting in an extremely simple configuration.In the invention of claim 3, the large-width square column is made significantly wider in the width direction perpendicular to the longitudinal direction than the small-width square column, resulting in a stall with superior mechanical strength and stability compared to a stall consisting only of square columns equivalent to conventional small-width square columns.

[0024] In the invention of claim 4, when the upright X-pillars are placed upright in an X-shape, there is a fixing point below the pivot, further improving the stability of both upright X-pillars when the stall is in use. In the invention of claim 5, the lower connecting rod and the upper connecting rod are attached to the narrow rectangular pillar using mounting screws with a knob on the screw shaft that can be turned by hand, so the stall of this invention can be assembled without using any tools. In the invention of claim 6, a rear banner is provided at the upper rear end of both upright X-pillars, allowing food to be sold at the stall.

[0025] The pivot section is equipped with a pivot connector, which uses a low-head bolt with a flat head, which minimizes the protrusions from the vertical X-column. This makes it easy to bundle multiple folded vertical X-column units and makes it difficult for workers to get caught on them during transport, allowing for safe transport. Furthermore, because the low-head bolts are used when the vertical X-column units are folded, protrusions are kept to a minimum, and multiple bundled vertical X-column units (30 or more) can be loaded onto a van without interference from the protruding parts.

[0026] Other benefits include the fact that by reducing the cross angle in the vertical direction when the vertically placed X-shaped column is formed, the ceiling, or awning, can be made higher, making the seller's face more visible even when a pop-up or other sign is displayed in front of the store. It also makes the inside of the store brighter. It also has the effect of reducing the depth of the stall, making it more compact. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0028] The present invention will be described below with reference to the drawings. First, the stall of the present invention comprises two vertically-mounted X-pillar bodies A, A, a lower connecting rod 51, an upper connecting rod 52, an awning 61, a top plate 7, and mounting screws 8. FIG. 1(A) is a perspective view of the stall of the present invention, and FIGS. 2(B) and (C) are perspective views of the stall in a horizontal position during the assembly process. Two vertically-mounted X-pillar bodies A are required for one stall, and two vertically-mounted X-pillar bodies A, A are connected to each other by a lower connecting rod 51 and an upper connecting rod 52 to form a set (see FIGS. 1(A), 5, etc.). The lower connecting rod 51 and the upper connecting rod 52 will be explained after the explanation of the vertically-mounted X-pillar body A.

[0029] In the assembly process of the stall of the present invention, the vertical X-pillar body A is initially placed horizontally, and just before the assembly of the stall is nearly completed, it can be inverted from the horizontal position to become a usable stand. Inversion means rotating the stall approximately 90 degrees from the horizontal position, and standing up the stall together with the horizontally placed vertical X-pillar body A (see Figures 1, 2(C) and (D)).

[0030] The vertically-mounted X-pillar A is composed of a large-width rectangular pillar 1, a small-width rectangular pillar 2, a pivotal connector 3, and a fixing device 4. The large-width rectangular pillar 1 and the small-width rectangular pillar 2 are long and of equal length. The large-width rectangular pillar 1 and the small-width rectangular pillar 2 in the vertically-mounted X-pillar A are connected by the pivotal connector 3 at their respective midpoints in the longitudinal direction, and the point where they are pivotally connected by the pivotal connector 3 is called the pivot part P of the vertically-mounted X-pillar A.

[0031] The pivot part P is composed of a pivot connector 3 and pivot holes 11 and 21, which will be described later. The large and small rectangular pillars 1 and 2, which are adjacent in parallel, are folded in a generally straight line (see Figure 3(A)). The large and small rectangular pillars 1 and 2 are then rotated around the pivot part P as the center of rotation, spreading them out in a cross shape, and fixing devices 4 are attached near the pivot parts P of the large and small rectangular pillars 1 and 2, resulting in an X-shaped, upright X-pillar body A, which will serve as a pillar for a food stall (see Figures 1 and 4(A)). The upright X-pillar body A can be used as the main pillar of a food stall when configured in an X-shape.

[0032] A pair of vertical X-shaped pillars A, A are arranged symmetrically at a predetermined distance. Specifically, in both vertical X-shaped pillars A, A, the large rectangular pillars 1, 1 are located on the outer side of the stall, and the small rectangular pillars 2, 2 are located on the inner side of the stall (see Figures 1(A), 5(A), (B), etc.). In other words, when looking at the stall from the front, the left vertical X-shaped pillar A has the large rectangular pillar 1 on the left and the small rectangular pillar 2 on the right.

[0033] Furthermore, the vertical X-pillar A on the right side of the stall when viewed from the front has the wide rectangular pillar 1 on the right side and the narrow rectangular pillar 2 on the left side (see Figure 1(A)). The vertical X-pillar A shown in Figures 3 and 4 is the one on the left side when viewed from the front of the stall. The front side of the stall is the side where visitors mainly stand, and the rear side of the stall is the side where event participants who are staff stand.

[0034] Figure 5(A) is a plan view of two vertically-placed X-shaped pillars A, A placed horizontally in parallel with a predetermined distance between them. Figure 5(B) is a partial cross-sectional front view of two vertically-placed X-shaped pillars A, A placed horizontally in parallel with a predetermined distance between them. These figures show that the two vertically-placed X-shaped pillars A, A are arranged symmetrically.

[0035] The large-width rectangular pillar 1 and the small-width rectangular pillar 2 in each vertically placed X-pillar A are both long wooden timbers of the same length, with their long length direction being the longitudinal direction, and the cross section perpendicular to this longitudinal direction being rectangular. The longitudinal direction is shown in the main drawings. The cross section of the large-width rectangular pillar 1 is labeled with the long side 1a and the short side 1b. Similarly, the cross section of the small-width rectangular pillar 2 is labeled with the long side 2a and the short side 2b.

[0036] The dimensions of the short sides 1b and 2b of the large-width rectangular pillar 1 and the small-width rectangular pillar 2 are the same, but the dimensions of the long sides 1a and 2a of the large-width rectangular pillar 1 are larger than those of the small-width rectangular pillar 2. Specifically, the large-width rectangular pillar 1 is a square timber with the short side 1b and long side 1a of the cross section measuring approximately 30 mm x 90 mm, while the short side 2b and long side 2a of the cross section of the small-width rectangular pillar 2 is a square timber with the short side 2b and long side 2a of the cross section measuring approximately 30 mm x 40 mm. The longitudinal length of the large-width rectangular pillar 1 and the small-width rectangular pillar 2 is approximately 2430 mm. With these dimensions, the depth of the stall of the present invention is approximately 1260 mm.

[0037] The above values ​​are shown as examples, and are not limited to these values ​​and may be changed as appropriate depending on the size of the stall. In the present invention, it is preferable that the long side 1a of the cross section perpendicular to the longitudinal direction of the large-width rectangular pillar 1 in the upright X-pillar A and the long side 2a of the cross section perpendicular to the longitudinal direction of the small-width rectangular pillar 2 be approximately twice the size of the long side 1a of the large-width rectangular pillar 1 as compared to the long side 2a of the small-width rectangular pillar 2.

[0038] Furthermore, although the cross section of the narrow rectangular pillar 2 has been described as being rectangular, it may also be substantially square. In the description of the present invention, the long and short sides 1a and 1b of the wide rectangular pillar 1 also include the side surfaces along the longitudinal direction corresponding to each side. Similarly, the long and short sides 2a and 2b of the narrow rectangular pillar 2 also include the side surfaces along the longitudinal direction corresponding to each side. The direction along the long and short sides 1a and 2a of the wide rectangular pillar 1 and the narrow rectangular pillar 2, respectively, is defined as the width direction of the wide rectangular pillar 1 and the narrow rectangular pillar 2. The direction along the short sides 1b and 2b of the wide rectangular pillar 1 and the narrow rectangular pillar 2, respectively, is defined as the thickness direction of the wide rectangular pillar 1 and the narrow rectangular pillar 2.

[0039] As mentioned above, one stall requires two vertical X-shaped pillars A. Each vertical X-shaped pillar A is pivotally connected to one wide rectangular pillar 1 and one narrow rectangular pillar 2 at the midpoint in the longitudinal direction via a pivot connector 3. The pivotal connection point is called the pivot point P (see Figures 3(A), (B), 4(A), (B), etc.).

[0040] The pivot point P is located at the midpoint of the large-width rectangular column 1 and the small-width rectangular column 2 in the longitudinal direction, but it may also be located slightly closer to the bottom end of both the large-width rectangular column 1 and the small-width rectangular column 2 than the longitudinal center. This allows the vertically-mounted X-pillar A to become a narrower vertically-mounted X-pillar A, with its width approximately half its length when it is expanded into an X shape around the pivot point P.

[0041] Therefore, the distance between the upper ends of the large-width square pillar 1 and the small-width square pillar 2 is slightly wider than the distance between the lower ends of each pillar, and a larger area can be obtained for the awning 61 (described later) attached to the upper end side (see Figure 1(A)). In the present invention, positions slightly away from the longitudinal center of each of the large-width square pillar 1 and the small-width square pillar 2 are also considered to be included in the range of the longitudinal intermediate point.

[0042] The vertically-mounted X-pillar A is folded in a straight line with the large-width rectangular pillars 1 and the small-width rectangular pillars 2 arranged side by side, and then rotates about the pivot point P to open and form an X-shape (see Figs. 3(A) and 4(A)). Furthermore, when the vertically-mounted X-pillar A is opened and spread out in an X-shape, the large-width rectangular pillars 1 and the small-width rectangular pillars 2 are fixed to each other by fasteners 4. The means for opening and fixing the vertically-mounted X-pillar A in an X-shape will be described later.

[0043] First, the large-width rectangular column 1 has a pivot hole 11 formed at its longitudinal midpoint between the opposing long sides 1a, 1a, i.e., penetrating through its thickness (see Figures 3(C) and (D)). Similarly, the small-width rectangular column 2 has a pivot hole 21 formed at its longitudinal midpoint between the opposing long sides 2a, 2a, i.e., penetrating through its thickness (see Figures 3(C) and (D)).

[0044] To facilitate understanding of the pivot point P in the vertically-placed X-pillar body A, the large-width rectangular pillar 1 and the small-width rectangular pillar 2 are explained in a folded and horizontally placed state (see Figure 3(A)). In the horizontally placed state, the large-width rectangular pillar 1 and the small-width rectangular pillar 2 are arranged side by side so that their linear directions are aligned horizontally, and the cross sections of the large-width rectangular pillar 1 and the small-width rectangular pillar 2 perpendicular to their longitudinal directions form a roughly L-shape (see Figures 3(B), (F), 5(B), and (C)). Similarly, in another vertically-placed X-pillar body A, the cross sections of the large-width rectangular pillar 1 and the small-width rectangular pillar 2 perpendicular to their longitudinal directions form a roughly inverted L-shape (see Figures 5(B) and (C)).

[0045] In this state, the large-width rectangular column 1 and the small-width rectangular column 2 are pivotally connected at their longitudinal midpoints by a pivot connector 3, and a pivot point P is provided on the vertically-placed X-shaped column A. A specific example of the pivot connector 3 is made up of a bolt material 31 and a nut material 32 (see Figure 3(C)). The bolt material 31 and the nut material 32 are preferably low-head bolts and low-head nuts, that is, bolts with flat dish-shaped heads.

[0046] By using low-head bolts and low-head nuts for the bolt material 31 and nut material 32, when the stall is disassembled (dismantled) and transported to a predetermined location, large protrusions are prevented from being created by the pivot connector 3 when many vertically-mounted X-pillar bodies A, A, ... are bundled together, and many vertically-mounted X-pillar bodies A can be transported in the cargo bed of a car. Note that when the bolt material 31 and nut material 32 are low-head bolts and low-head nuts, what is called a joint connector bolt and joint connector nut may also be used.

[0047] The bolt material 31 has a head 31a that is approximately flat and dish-shaped, with a hexagonal hole in its center for a hexagonal wrench. The backside of the head 31a is a threaded shank 31b (see Figures 3(C) and (F)). The length of the threaded shank 31b of the bolt material 31 is approximately equal to or slightly longer than the overall thickness dimension of the large-width rectangular column 1 and the small-width rectangular column 2, which are adjacent and face each other with their opposing short sides 1b and 2b abutting against each other in the vertically-mounted X-shaped column A. The length of the tubular portion 32b of the nut material 32 can be set as appropriate and may conform to the standard for commercially available low-head nuts.

[0048] A pivot hole 11 is formed at the longitudinal middle (including approximately the middle) of the large-width rectangular column 1, and a pivot hole 21 is formed at the longitudinal middle (including approximately the middle) of the small-width rectangular column 2 (see Figures 3(C) and (D)). The pivot hole 11 of the large-width rectangular column 1 and the pivot hole 21 of the small-width rectangular column 2 have the same diameter.

[0049] When the large-width rectangular column 1 and the small-width rectangular column 2 are arranged in parallel and adjacent to each other, and when the cross sections perpendicular to the longitudinal direction of both are arranged in an L-shape, and the short sides 1b and 2b located at the lower ends of the long sides 1a and 2a, i.e., on the underside, are aligned at the same position, the centers of the diameters of the pivot holes 11 and 21 are at the same height [see Figure 3(F)].

[0050] The pivot hole 11 of the large-width rectangular column 1 and the pivot hole 21 of the small-width rectangular column 2 have an inner diameter large enough to insert the tubular portion 32b of the nut material 32, and naturally, the threaded shank 31b of the bolt material 31 can be inserted loosely into both holes (see Figure 3(D)). The pivot hole 11 of the large-width rectangular column 1 and the pivot hole 21 of the small-width rectangular column 2, together with the pivot connector 3, form the pivot part P of the vertically placed X-column body A.

[0051] Then, the tubular portion 32b of the nut material 32 is inserted into either the pivot hole 11 of the large-width rectangular pillar 1 or the pivot hole 21 of the small-width rectangular pillar 2, and the threaded shank 31b of the bolt material 31 is loosely inserted from the other side, and the threaded shank 31b of the bolt material 31 screws into the internal thread of the tubular portion 32b of the nut material 32, connecting the bolt material 31 and the nut material 32. Then, the head 31a of the bolt material 31 and the head 32a of the nut material 32 sandwich the side surfaces of the long sides 1a and 2a of the large-width rectangular pillar 1 and the small-width rectangular pillar 2 on the sides that are spaced apart in the thickness direction, thereby pivotally connecting the large-width rectangular pillar 1 and the small-width rectangular pillar 2 (see Figure 3(F)).

[0052] This allows the large-width rectangular column 1 and the small-width rectangular column 2 to be folded in a straight line in a parallel state (see Fig. 3(A)), or to be expanded into an X-shaped state (see Fig. 4(A)) with the pivot point P as the center of rotation. If necessary, a washer 33 may be added to the pivot connector 3 to clamp the long sides 1a and 2a of the large-width rectangular column 1 and the small-width rectangular column 2 together (see Fig. 3(C)).

[0053] Next, a fixing hole 12 is formed in the large-width rectangular pillar 1 of the vertically-placed X-pillar body A, and a fixing hole 22 is formed in the small-width rectangular pillar 2. The fixing holes 12 of the large-width rectangular pillar 1 and the fixing holes 22 of the small-width rectangular pillar 2 are formed near their respective pivot points P. In other words, the fixing hole 12 of the large-width rectangular pillar 1 is formed near the pivot hole 11, and the fixing hole 22 of the small-width rectangular pillar 2 is formed near the pivot hole 21.

[0054] The fixing holes 12 of the large-width rectangular pillar 1 and the fixing holes 22 of the small-width rectangular pillar 2 are formed at positions equidistant from the position of the pivot point P. The pivot hole 21 and the fixing holes 22 of the small-width rectangular pillar 2 are formed at a predetermined interval along the longitudinal direction. The line segment connecting the diametric center of the pivot hole 21 and the diametric center of the fixing hole 22 is formed on the center line T2 along the longitudinal direction of the long side 2a of the small-width rectangular pillar 2 (see Figure 3(D)).

[0055] Therefore, in the horizontally placed narrow rectangular column 2, the heights of the fixing holes 22 and the pivot holes 21 from the lower short side 2b are the same (see Fig. 3(D)). The fixing holes 12 of the wide rectangular column 1 are formed near the upper ends of the long sides 1a of the wide rectangular column 1 when placed horizontally. In other words, the fixing holes 12 are formed at positions above the center line T1 along the width and longitudinal directions of the wide rectangular column 1 (see Fig. 3(D)).

[0056] The distance L1 between the diametric center of the pivot hole 11 of the large-width rectangular column 1 and the diametric center of the fixing hole 12 is equal to the distance L2 between the diametric center of the pivot hole 21 of the small-width rectangular column 2 and the diametric center of the fixing hole 22. In other words, L1=L2.

[0057] Furthermore, because the distances L1 and L2 are equal, there is a state in which the positions of the fixing holes 12 of the large-width square column 1 and the fixing holes 22 of the small-width square column 2 coincide during the process of expanding the large-width square column 1 and the small-width square column 2 with the pivot point P as the center of rotation (see Figures 4(C) and (D)).

[0058] Furthermore, the positions of the fixing holes 12 in the large-width rectangular column 1 and the fixing holes 22 in the small-width rectangular column 2 must be within a range such that when the large-width rectangular column 1 and the small-width rectangular column 2 are expanded into an X shape around the pivot point P, the large-width rectangular column 1 and the small-width rectangular column 2 intersect and overlap. In other words, when the large-width rectangular column 1 and the small-width rectangular column 2 form an X shape, the fixing holes 12 and the fixing holes 22 must be aligned and overlapping (see Figures 4(C), (D), and (E)). When the fixing holes 12 in the large-width rectangular column 1 and the fixing holes 22 in the small-width rectangular column 2 are aligned and the shaft-shaped fasteners 4 can be inserted into the fixing holes 12 and 22, the X shape is suitable for use as the main column of a stall.

[0059] Furthermore, if the distance between the short side 1b of the lower end of the wide rectangular pillar 1 in the horizontal position and the pivot hole 11 is H1, and the distance between the short side 2b of the lower end of the narrow rectangular pillar 2 and the pivot hole 21 is H2, then the distance H1 and the distance H2 are equal. In other words, H1=H2.

[0060] As mentioned above, the distance H2 is equal to the distance from the short side 2b on the lower end side of the center line T2 along the longitudinal direction of the long side 2a of the narrow rectangular column 2. Therefore, the position of the pivot hole 11 of the wide rectangular column 1 in the horizontally placed state is at the same position as the center line T2 of the narrow rectangular column 2.

[0061] The positional relationship between the pivot hole 11 and the fixing hole 12 in the large rectangular column 1 of the vertically-mounted X-pillar A will be explained. The position of the fixing hole 12 in the large rectangular column 1 determines the angle θ at which the large rectangular column 1 intersects with the small rectangular column 2 when the vertically-mounted X-pillar A is configured as an X. This angle θ is the angle between the upper ends or lower ends of the large rectangular column 1 and the small rectangular column 2 when the vertically-mounted X-pillar A is in use as a stall, i.e., when it is placed upright (see Figures 2(D) and (E)).

[0062] The angle θ is set as follows. First, an imaginary line q1 is set starting from the diametric center of the pivot hole 11 of the large-width rectangular column 1 and running along the longitudinal direction of the long side 1a of the large-width rectangular column 1. This imaginary line q1 is parallel to the center line T1 along the longitudinal direction of the large-width rectangular column 1. Next, an imaginary line q2 is set connecting the diametric center of the pivot hole 11 and the diametric center of the fixing hole 12. The angle between the imaginary lines q1 and q2 is defined as θ (see Figure 3(D)). Note that when the large-width rectangular column 1 and the small-width rectangular column 2 are placed horizontally in a straight line parallel to each other, the imaginary line q1 is parallel to the center line T2 of the small-width rectangular column 2 and its line direction is horizontal.

[0063] As mentioned above, this angle θ determines the angle between the upper ends or lower ends of the large-width rectangular pillar 1 and the small-width rectangular pillar 2 when the vertically-positioned X-pillar A is set up on a stall, i.e., when it is placed upright (see Figures 2(D) and (E)). This angle θ is preferably between about 60 and 70 degrees, with about 65 degrees being particularly suitable, as this will optimize the shape and balance of the X-shaped vertically-positioned X-pillar A.

[0064] As mentioned above, in the parallel and straight arrangement of the large-width rectangular column 1 and the small-width rectangular column 2, the center line T2 along the longitudinal direction of the long side 2a of the small-width rectangular column 2 is set to pass through the pivot point P. Therefore, in the cross section of the large-width rectangular column 1, the position of the pivot point P is below the center line T1 of the large-width rectangular column 1 in the width direction of the long side 1a and coincides with the center line T2 of the small-width rectangular column 2.

[0065] Then, by rotating the large-width square pillar 1 and the small-width square pillar 2 around the pivot point P and expanding them into an X shape, the position of the fixing hole 12 in the large-width square pillar 1 and the position of the fixing hole 22 in the small-width square pillar 2 become aligned, and fixing device 4, which is a rod-shaped shaft member, can be inserted into fixing holes 12 and 22 (see Figure 4(C)). Then, by inserting fixing device 4 into fixing holes 12 and 22, the large-width square pillar 1 and the small-width square pillar 2 are fixed in an X-shaped cross state, and the upright X-pillar body A becomes ready to be used as the main pillar of a stall.

[0066] Fixing device 4 is a shaft-shaped member with a circular cross section, and its diameter is smaller than the diameter (which may be referred to as the inner diameter) of fixing hole 12 and fixing hole 12, making it possible to easily insert fixing device 4 into fixing hole 12 and fixing hole 22. Preferably, fixing hole 12 is slightly smaller than the diameter (which may be referred to as the inner diameter) of fixing hole 22, and it is preferable that fixing device 4 is difficult to remove even if some force is required when inserting it.

[0067] The axial length of the shaft-shaped fastener 4 is set to a dimension longer than the sum of the thicknesses of the short sides 1b and 2b of the large-width rectangular column 1 and the small-width rectangular column 2. Specifically, the length of the fastener 4 preferably has a protruding portion that allows the fastener 4 to be easily inserted into and removed from the consecutively adjacent fastener holes 12 and 22 (see Figures 4(B), (C), and (E)).

[0068] The fasteners 4 can be inserted and removed from either the fixing hole 12 side of the large-width rectangular pillar 1 or the fixing hole 22 side of the small-width rectangular pillar 2. By placing the two upright X-pillar bodies A, A horizontally while fixed in an X-shape, the two upright X-pillar bodies A, A are in a low state, which makes it easier to attach the awning 61, and it is also easy to attach the top plate body 7 to the upright X-pillar bodies A, A while they are left in a horizontal position.

[0069] As a result, when the vertically-mounted X-pillar A is placed in a straight line with its lengthwise direction on a flat ground or floor, if the short side of the narrow rectangular pillar 2 is in contact with the ground, the cross section of the vertically-mounted X-pillar A will be L-shaped, allowing it to be placed stably on the ground. A fixing hole 12 is formed in the large rectangular pillar 1 near the position of the pivot point P, and a fixing hole 12 is also formed in the small rectangular pillar 2 near the pivot point P. The fixing holes 12 of the large rectangular pillar 1 and the small rectangular pillar 2 are configured to coincide when the two pillars are opened and rotated in an X-shape around the pivot point P.

[0070] Next, we will explain the lower connecting rod 51 and the upper connecting rod 52. The lower connecting rod 51 and the upper connecting rod 52 are members that connect the two upright X-pillar bodies A, A in a parallel state with left-right symmetry. The lower connecting rod 51 is attached to the lower end or a position close to the lower end in the longitudinal direction of both narrow rectangular pillars 2, 2 of both upright X-pillar bodies A, A, and the upper connecting rod 52 is attached to the upper end or a position close to the upper end in the longitudinal direction.

[0071] A threaded hole 23 for a mounting screw 8 is formed at the lower longitudinal end of each of the narrow rectangular columns 2, 2 to attach the lower connecting rod 51, and a threaded hole 23 for a mounting screw 8 is formed at the upper longitudinal end of each of the narrow rectangular columns 2, 2 to attach the upper connecting rod 52 (see Figures 5(B) and (C)). The threaded hole 23 has an internal thread formed on the inner periphery of the hole, and is threadedly engaged with the screw shank 81 of the mounting screw 8 (see Figures 5(B) and (C)).

[0072] The lower connecting rod 51 is attached to the two narrow rectangular pillars 2, 2 located at the front and bottom ends of the two upright X-pillars A, A. The upper connecting rod 52 is attached to the two narrow rectangular pillars 2, 2 located at the rear and top ends of the two upright X-pillars A, A. The lower connecting rod 51 is formed from a roughly rectangular flat plate or flat strip material (see Figures 1(A), 5(A), (D), and (E)). The upper connecting rod 52 is made of the same material or a roughly equivalent rectangular material with the same cross-sectional shape as the narrow rectangular pillar 2. The lower connecting rod 51 and the upper connecting rod 52 may also be made of the same material with the same cross-sectional shape as the narrow rectangular pillar 2 (see Figure 6(D)). The longitudinal lengths of the lower connecting rod 51 and the upper connecting rod 52 are the same. Therefore, the lower connecting rod 51 and the upper connecting rod 52 also play a role in determining the distance between the two upright X-shaped pillars A, A arranged in parallel (see FIGS. 5(A) to 5(C)).

[0073] The lower connecting rod 51 and the upper connecting rod 52 have mounting holes 51a, 51a and mounting holes 52a, 52a formed near both longitudinal ends. The lower connecting rod 51 and the upper connecting rod 52 are arranged at the lower end positions of the narrow rectangular pillars 2, 2 of the parallel-arranged upright X-pillar bodies A, A, and are attached and fixed to the lower and upper ends of the narrow rectangular pillars 2, 2 by aligning the screw hole 23 of the narrow rectangular pillar 2 with the mounting holes 51a, 52a of the lower connecting rod 51 and the upper connecting rod 52 with mounting screws 8 (see Figures 5(A) to 5(C)). The lower connecting rod 51 is attached to the forward and downward protruding portions of the two narrow rectangular pillars 2, 2 of the two vertically-mounted X-pillar bodies A, A of the stall, and the upper connecting rod 52 is attached to the rear and upward protruding portions of the two narrow rectangular pillars 2, 2 (see Figures 1(A), 2(D), and (C)).

[0074] The mounting screw 8 has a relatively thick knob 82 provided on a screw shaft 81 (see FIG. 5(D)). The outer periphery of the knob 82 has a circumferential side surface with an uneven surface, allowing the worker to manually turn the knob 82 with the fingertips of the hand.

[0075] As a result, when assembling the stall and attaching the lower connecting rod 51 and the upper connecting rod 52 to the two narrow rectangular pillars 2, 2, the worker can insert and screw the screw shank 81 of the mounting screw 8 into the mounting holes 51a and 52a of the lower connecting rod 51 and the upper connecting rod 52 and into the screw hole 23 of the narrow rectangular pillar 2, by manually rotating the knob 82 of the mounting screw 8, and can secure the lower connecting rod 51 and the upper connecting rod 52 to the lower ends of the two narrow rectangular pillars 2, 2 without using any tools. When the two narrow rectangular pillars 2, 2 of the two upright X-pillar bodies A, A are connected to each other by the lower connecting rod 51 and the upper connecting rod 52, a substantially rectangular frame is formed (see Figures 5(A) and (D)).

[0076] The awning 61 has a sheet portion 61a and an attachment rod portion 61b, with the attachment rod portions 61b, 61b provided on both front and rear sides of the rectangular sheet portion 61a. The attachment rod portion 61b is a rod-shaped material with a circular cross section, and the front and rear ends of the rectangular sheet portion 61a are wrapped around the attachment rod portion 61b, with the ends of the sheet portion 61a sewn and attached to the attachment rod portion 61b.

[0077] Alternatively, the sheet portion 61a may be wrapped around the mounting rod portion 61b and attached to the mounting rod portion 61b with fasteners such as hooks, rivets, etc. In the case of the sheet portion 61a using hooks, the sheet portion 61a and the mounting rod portion 61b can be separated from each other, allowing only the sheet portion 61a to be cleaned, and even if the sheet portion 61a gets wet in the rain, it can be dried and maintained in a hygienic and clean state.

[0078] In addition, awning mounting holes 14 and 24 are formed at the upper ends of the large square pillars 1 and the small square pillars 2 of the vertically-mounted X-pillar bodies A, A. In the stall, the upper ends of the large square pillars 1, 1 of the vertically-mounted X-pillar bodies A, A protrude forward, and the upper ends of the small square pillars 2, 2 protrude backward.

[0079] Then, both axial ends of the mounting rod portion 61b on the front side of the awning 61 are inserted into the awning mounting holes 14, 14 at the upper ends of the two wide rectangular pillars 1, 1 of the two upright X-pillar bodies A, A, and both axial ends of the mounting rod portion 61b on the rear side of the awning 61 are inserted into the awning mounting holes 24, 24 at the upper ends of the two narrow rectangular pillars 2, 2, thereby attaching the awning 61 to the upper ends of the two upright X-pillar bodies A, A.

[0080] 6(A) shows the vertically-placed X-pillar A in an X-shape and then placed horizontally, with the upper end of the large-width rectangular pillar 1 positioned above and the upper end of the small-width rectangular pillar 2 positioned below. The figure shows the state in which the shaft end of the front mounting rod 61b of the awning 61 is about to be inserted into the awning mounting hole 14 at the upper end of the large-width rectangular pillar 1 on the upper side, and the state in which the shaft end of the rear mounting rod 61b of the awning 61 is about to be inserted into the awning mounting hole 24 at the upper end of the small-width rectangular pillar 2 on the lower side.

[0081] In addition to the awning 61, a rear curtain 62 may also be installed in the stall from the rear upper end of each of the upright X-pillars A, A toward the bottom of the stall (see Figures 6(C) and (D)). The rear curtain 62 has a hanging sheet portion 62a to which an attachment rod portion 62b is attached at the top end. The rear curtain 62 is required when food is handled at the stall. The attachment rod portion 62b at the top end of the hanging sheet portion 62a of the rear curtain 62 is attached to the attachment rod portion 61b on the rear side of the awning 61 by various means.

[0082] This can be achieved by attaching the mounting rod 62b of the rear curtain 62 to the mounting rod 61b of the awning 61 using a rubber ring, string, etc. Alternatively, it is also possible to form through-holes similar to the awning mounting holes 24 in the upper ends of the narrow rectangular pillars 2 of both upright X-pillars A, and insert both axial ends of the mounting rod 62b of the rear curtain 62 into the through-holes to attach the rear curtain 62 to both upright X-pillars A.

[0083] Furthermore, in a stall, side curtains 63, 63 may be provided on each of the two upright X-pillars A, A along with the awning 61 and rear hanging curtain 62 (see Fig. 6(D)). The side curtains 63 are provided on both sides of the width of the stall, and similarly to the rear hanging curtain 62, mounting rods 63b are attached to the upper ends of the side hanging sheet portions 63a. The longitudinal ends of the mounting rods 63b of the side curtains 63 are attached to the front and rear mounting rods 61b, 61b of the awning 61 by various means.

[0084] This is achieved by attaching the mounting rod 62b of the rear curtain 62 to the mounting rod 61b of the awning 61 using rubber rings, string, or the like. By providing side curtains 63, 63 on both sides of the width of the stall, the top, rear, and sides of the stall are covered except for the front side, which is particularly necessary when the stall handles food. Furthermore, an apron 64 may be attached to the front end of the top board 7 (see the two-dot chain line in Figure 6(D)). The apron 64 may be made of fabric, a resin plate, or the like, and may bear information such as the name of the product being sold, product advertisements and promotions, and the store name.

[0085] Next, the tabletop body 7 is made of wood and is composed of a tabletop portion 71 and an arm-shaped frame portion 72 (see Figures 1(A) and 6(B)). The tabletop portion 71 is a rectangular member and is composed of multiple wooden boards or a single veneer. In the present invention, the tabletop portion 71 is composed of three boards. The width direction of the tabletop portion 71 is set to be approximately equal to or slightly smaller than the distance between the opposing inner long sides 2a, 2a of the two narrow rectangular pillars 2, 2 located on the inner side of the two upright X-shaped pillars A, A of the stall.

[0086] Arm-shaped frame portions 72, 72 are arranged on both sides of the top panel portion 71 in the width direction. Both arm-shaped frame portions 72, 72 are formed on the underside of the top panel portion 71 so as to protrude rearward in the vertical width direction. Top panel through-holes 73 are formed in both arm-shaped frame portions 72, 72, and two top panel through-holes 73 are formed in each arm-shaped frame portion 72 at a predetermined interval along the longitudinal direction of the arm-shaped frame portion 72. In addition, a top panel mounting through-hole 15 is formed at a position below the pivot point P of the large-width rectangular column 1 of the upright X-pillar body A, and a top panel mounting through-hole 25 is formed at a position below the pivot point P of the small-width rectangular column 2.

[0087] When the stall is placed upright, the top plate mounting through-holes 15 and 25 of the vertically-placed X-pillars A, A are set to be the same height from the flat ground on which the stall is placed (see Figure 2(D)). The top plate mounting fixture 9 is a shaft-shaped member with the same diameter and length as the fixing fixture 4. In other words, the top plate mounting fixture 9 has the same shape as the fixing fixture 4 and can be used in common.

[0088] Furthermore, when the vertical X-pillar body A is placed upright in an X-shape and ready for use, the top plate mounting through-holes 15 and 25 are at the same height, so the top plate portion 71 of the top plate body 7 attached to both vertical X-pillar bodies A, A can be made horizontal (see Figures 1(A) and 2(E)). The front end of the top plate portion 71 of the top plate body 7 is configured to protrude further forward than the lower ends of the narrow rectangular pillars 2, 2 that protrude downward at the front side of the stall, and this protrusion amount is about 20 cm.

[0089] Next, we will explain the process for assembling the stall of the present invention. First, two vertical X-shaped pillars A, A are placed horizontally on the ground (see Figures 2(A) and 5(D)). At this time, the two vertical X-shaped pillars A, A are arranged parallel to each other with a predetermined distance between them, and the two vertical X-shaped pillars A, A are arranged symmetrically with the narrow rectangular pillars 2, 2 facing inward (see Figures 5(A), (B), and (C)).

[0090] Next, the lower connecting rod 51 and the upper connecting rod 52 are attached to the narrow rectangular columns 2, 2 of the two vertically placed X-shaped columns A, A with the mounting screws 8 (see Figures 5(B) and (C)). At this time, the two horizontally placed parallel vertically placed X-shaped columns A, A are arranged symmetrically so that the narrow rectangular columns 2, 2 are on the inside and the wide rectangular columns 1, 1 are on the outside (see Figures 5(A), (B) and (C)). Therefore, the cross sections perpendicular to the longitudinal direction of both vertically placed X-shaped pillars A, A are L-shaped and inverted L-shaped, and the lower connecting rod 51 and the upper connecting rod 52 are arranged at the lower and upper longitudinal ends of both narrow rectangular pillars 2, and both sides of the lower connecting rod 51 and the upper connecting rod 52 in the width direction are surrounded by the wide rectangular pillars 1, 1, making it easy to arrange the lower connecting rod 51 and the upper connecting rod 52 between both vertically placed X-shaped pillars A, A (see Figure 5(B)).

[0091] The head of the mounting screw 8 has a knob 82 (see Fig. 5(D)), and the mounting screw 8 can be manually screwed into the multiple screw holes 23, 23, ... formed in the narrow rectangular pillars 2, 2 (see Figs. 5(B) and (C)). By fastening the lower connecting rod 51 and the upper connecting rod 52 to the vertically-placed X-pillar bodies A, A with the mounting screw 8, the vertically-placed X-pillar bodies A, A are connected in a parallel state via the lower connecting rod 51 and the upper connecting rod 52, and the narrow rectangular pillars 2, 2, the lower connecting rod 51 and the upper connecting rod 52 form a substantially rectangular frame (see Fig. 5(A)).

[0092] Then, while both vertically-positioned X-pillar bodies A, A are left in a horizontal position, the large-width rectangular pillar 1 and the small-width rectangular pillar 2 are rotated around the pivot point P to spread them apart, forming an X shape with the large-width rectangular pillar 1 and the small-width rectangular pillar 2 at the pivot point P (see Figure 2(B)). Then, shaft-shaped fasteners 4 are inserted into the fixing holes 12 of the large-width rectangular pillar 1 and the fixing holes 22 of the small-width rectangular pillar 2 (see Figures 4(D) and (E)). This fixes the vertically-positioned X-pillar body A so that it maintains its X-shaped configuration (see Figures 1(B), 2(C), 4(A) and (B)).

[0093] Next, an awning 61 is attached to the upper ends of the large rectangular pillars 1 and the small rectangular pillars 2 of the two vertically-placed X-pillar bodies A, A. Then, the two horizontally-placed vertically-placed X-pillar bodies A, A are inverted to an upright position. That is, the horizontally-placed vertically-placed X-pillar bodies A, A are rotated 90 degrees around the lower ends of the large rectangular pillars 1, 1, and the two vertically-placed X-pillar bodies A, A are raised to an upright position, as shown in Figs. 1(C) to 1(A) and 2(C). When the two vertically-placed X-pillar bodies A, A are raised to an upright position, the small rectangular pillars 2, 2, the lower connecting rod 51, and the upper connecting rod 52 form a substantially rectangular frame, as described above. Therefore, the two small rectangular pillars 2, 2 do not shift, and the vertically-placed X-pillar bodies A, A can be raised to an upright position in a stable manner.

[0094] The arm-like frame portions 72, 72 of the top plate 7 are inserted between the narrow rectangular pillars 2, 2 of the vertically-placed X-pillar bodies A, A, and the top plate 7 is attached to the vertically-placed X-pillar bodies A, A with the top plate attachment fixtures 9, completing the assembly of the stall and making it complete. If necessary, rear curtains 62 may also be attached to the rear of the vertically-placed X-pillar bodies A, A of the stall. When disassembling or dismantling the stall, the above assembly process can be reversed.

[0095] That is, after removing the top plate 7 from both upright X-pillar bodies A, A, both upright X-pillar bodies A, A are laid down horizontally, the awnings 61 are removed from both upright X-pillar bodies A, A, both upright X-pillar bodies A, A are folded from their X-shape into a straight line, and the lower connecting rods 51 and upper connecting rods 52 are removed from both upright X-pillar bodies A, A, and this completes the disassembly (dismantling).

[0096] The outline of the configuration of the present invention is as follows: The device comprises a long, large-width rectangular pillar 1 and a small-width rectangular pillar 2 of the same length as the large-width rectangular pillar 1, the large-width rectangular pillar 1 and the small-width rectangular pillar 2 being overlapped with each other along the width direction so as to form an L-shaped cross section, and the large-width rectangular pillar 1 and the small-width rectangular pillar 2 are pivotally connected at their longitudinal intermediate points to form a pivot point P, the large-width rectangular pillar 1 and the small-width rectangular pillar 2 being configured in an X-shape by intersecting from a straight line with an angle θ of 60 to 70 degrees less than 90 degrees, and in this X-shape, the large-width rectangular pillar 1 and the small-width rectangular pillar 2 are connected to each other near the pivot point P. Fixing devices 4 are inserted into the fixing holes 12, 12 provided on each of the vertical X-pillar bodies A and fixed to each other, and two vertical X-pillar bodies A fixed in the X shape are provided facing each other at a specified interval with the narrow square pillar 2 on the inside, a lower connecting rod 51 is attached between the narrow square pillars 2, 2 near the lower end and an upper connecting rod 52 is attached near the upper end, an awning 61 is stretched between the upper ends of the vertical X-pillar bodies A, and a top plate body 7 is attached to both vertical X-pillar bodies A, A below the positions of the pivot points P, P.
