  In the stand panels (screen panels) described in Patent Documents 1 and 2, since the size of the legs to be in contact with the floor is large, the stand panel (screen panel) can be self-supporting. As a result, storage efficiency and transportation efficiency are reduced. In order to eliminate this problem, it is only necessary to disassemble the legs, but if this is done, it is necessary to reassemble the legs at the installation site, resulting in poor work efficiency.

  Since the stand panel (side screen) described in Patent Document 3 has a width at the lower end that is larger than that at the upper end so that it can stand on its own, as in the case described above, the packaging at the time of packaging becomes large, and storage and transportation There is a problem of inefficiency.

  The present invention has been made in view of the above-mentioned problems, and it is possible to reduce the front and rear dimensions when not in use without removing the legs, to improve storage and transportation efficiency, and to be excellent in assembly workability. The purpose is to provide.

According to the present invention, the above problem is solved as follows.
(1) At the lower ends of a pair of left and right side frames in the frame to which the panel material is attached, both end portions of the movable legs bent in a backward convex shape are brought into contact with the floor so as to be rotatable and facing rearward. It is attached so that it can be selectively fixed between the use state and the non-use state in which the side frame is substantially parallel to the vertical direction.

(2) In the above item (1), an engaged portion that prevents the movable leg from rotating between the use state and the non-use state on one of the opposing surfaces of the attachment portions of the side frame and the movable leg. On the other hand, an engaging portion that complements the engaged portion is provided.

(3) In the above item (2), a plurality of crests and troughs extending radially from the rotation center of the movable leg in the engaged part and the engaging part are alternately arranged in the circumferential direction. It shall be formed.

(4) In the above item (2) or (3), the connecting members are respectively fixed to the attachment portions of the side frames and the movable legs, and are inserted into the left and right insertion holes provided in one of the connecting members. Since the bolt is screwed into the screw hole to be provided on the other connecting member, the connecting members can be fixed to each other, and the engaged portion and the engaging portion are provided on the opposing surfaces of the connecting members.

(5) In any one of the above items (1) to (4), the panel material is made of a stretchable stretchable material, and this stretched material is stretched on a frame formed in a U-shape facing downward in a front view. .

(6) In the above item (5), the lower end of the panel material made of the upholstery is fixed to the movable leg.

(7) In the above item (6), a floor-contacting member that touches the floor in the use state is attached to the intermediate portion of the movable leg.

According to the first aspect of the present invention, the front-rear dimension of the stand panel is reduced by rotating and fixing the movable leg to the unused state substantially parallel to the left and right side frames without removing the movable leg. Therefore, when the stand panel is stored in a case or the like, it can be packed in a compact manner, and storage and transportation efficiency are improved.
In addition, since the stand panel can be formed immediately by simply rotating and fixing the movable leg from the non-use state to the use state, the assembling workability is extremely good.

  According to the second aspect of the present invention, when the engaging portion is engaged with the engaged portion, the movable leg is reliably prevented from rotating with respect to the side frame, so that the use state and the non-use state are obtained. Can be positioned and fixed.

  According to the third aspect of the present invention, the engaged portion and the engaging portion are formed by alternately forming a plurality of peaks and valleys in the circumferential direction, and the engagement area is large. , The effect of preventing the movable leg from rotating is increased.

According to the invention of claim 4, the side frame and the movable leg are attached via the connecting members fixed to the attaching portions, and both the connecting members can be directly fixed by the bolts. The strength of the attachment portion between the part frame and the movable leg increases, and there is no fear that the attachment portions will be deformed.
In addition, since the engaged portion and the engaging portion are provided on the opposing surfaces of both connecting members, for example, a high stand panel is formed, or the side frame and the movable leg are formed by narrow pipes. Even so, the movable leg can be firmly fixed to the side frame and prevented from rotating.

According to the fifth aspect of the present invention, it is possible to provide a stand panel having a lightweight and simple and inexpensive structure.
In addition, the panel material is made of a stretchable stretchable material. When the movable leg is not used, the stretchable material is pressed and stretched in the front-rear direction, and is recessed. It can be rotated until it is positioned between the opposed surfaces of the frame, and the front and rear dimensions of the stand panel when not in use are reduced.

According to the invention described in claim 6, since the lower end of the tension member is fixed to the movable leg, when the movable leg is rotated to the use state, tension is applied to the tension member, and the lower side thereof is The three-dimensional shape that bulges rearwardly is stretched nicely and the stability of the stand panel increases.
In addition, when the movable leg is not in use, the upholstery material sags. Therefore, the movable leg can be easily rotated to a position parallel to the opposite surfaces of the both side frames. The front and rear dimensions in use are reduced.
Furthermore, if the movable leg is not used, extra tension is not applied to the upholstery material, which lasts longer.

  According to the seventh aspect of the present invention, since a gap is formed between the lower surface of the upholstery material fixed to the movable leg and the floor surface, the lower surface of the upholstery material becomes dirty or damaged. Is prevented.

According to the eighth aspect of the present invention, the lower side of the upholstery material swells rearward in a three-dimensional curved shape in use, so that the appearance of the stand panel is further improved and the stability is also increased.
Moreover, since the movable leg is made of a bent pipe, it has a light feeling.

  According to the ninth aspect of the present invention, it is possible to easily form the stand panel by simply putting the movable leg in the use state and covering the tension material from above the frame, and removing the tension material to make it not in use. By covering the movable leg and the frame again from above, the longitudinal dimension of the entire stand panel can be reduced.

  According to the tenth aspect of the present invention, even if the floor surface is inclined or the stand panel is tilted backward so as not to fall forward, the floor contact plate swings around the pivot shaft. Since the lower surface always touches the floor, the stand panel can be stably installed on the floor surface.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a use state of the first embodiment of the stand panel of the present invention, FIG. 2 is a side view of the same, FIG. 3 is a perspective view of the non-use state, and FIG. FIG. 5 is a side view of the non-use state.

  The stand panel 1 has a substantially downward U-shape when viewed from the front (hereinafter described with the left side of FIG. 2 as the front) by an upper frame 2a facing left and right and a pair of left and right side frames 2b and 2b facing vertically. A pipe-shaped movable leg 3 in which a plane 2 in a use state forms a substantially backward convex arc shape, which connects a frame 2 formed of a pipe bent in a shape and opposed surfaces of lower ends of both side frames 2b. And.

  The upper frame 2a and both side frames 2b and the movable leg 3 in the frame 2 are formed on the peripheral edge of the panel material 4 made of a semi-translucent or translucent stretchable cloth or a tension material such as a sheet. The formed bag-like portion 4a is inserted, and the panel material 4 is stretched so as to bulge three-dimensionally toward the rear.

  7 to 9 show connecting members 5 and 6 for connecting the side frame 2b and the movable leg 3 (only the left one is shown in order to be symmetrical and have the same shape). The connecting shaft 5a that faces the upper side of the connecting member 5 that is perpendicular to is fixed to a lower end portion of the side frame 2b and fixed by a set screw 8 that is screwed into the female screw hole 7 of the connecting shaft 5a. A connecting shaft 6a facing inward in the use state of the other connecting member 6 having a square shape is fitted to a side end portion of the movable leg 3 and screwed into the female screw hole 7 of the connecting shaft 6a. It is fixed by screws 8.

As shown in FIG. 7, in the cylindrical protrusion 5 b protruding from the inner surface of the connecting member 5, a peak portion facing the radial direction around the bottomed shaft hole 9 facing the left-right direction is formed on the inner end surface. By forming the valleys and the valleys alternately at intervals of 90 degrees in the circumferential direction, the concave-convex anti-rotation engaged portions 10 are provided.
Further, the outer surface of the circular protrusion 6b, which has the same diameter as the cylindrical protrusion 5b and protrudes from the outer surface of the lower end portion of the connecting member 6 and has the bolt insertion hole 11 at the center, is connected to the engaged surface. An anti-rotation engaging portion 12 that is complementary to the portion 10 and can be fitted to the portion 10 is projected.

  When the engaging portion 12 is fitted to the engaged portion 10, the connecting member 6 is prevented from rotating with respect to the connecting member 5 in steps of 90 degrees. Therefore, the bolt 13 inserted from the inside into the bolt insertion hole 11 of the connecting member 6 is formed in the inner part of the shaft hole 9 of the connecting member 5 and screwed into a screw (not shown), thereby connecting the connecting member 6 and As shown in FIGS. 1, 2 and 8, the movable leg 3 connected to the movable leg 3 can be fixed by being prevented from rotating in a use state in which the movable body 3 is rearwardly horizontal. Similarly, as shown in FIGS. 3 to 5 and 9, the connecting member 6 and the movable leg 3 are parallel to the connecting member 5 and the inner side surface of the side frame 2 b connected to the connecting member 5. It can be fixed in a non-use state.

  In order to put the movable leg 3 in the use state and the non-use state, the bolt 13 is loosened and the lower end of the frame 2 is expanded outward, or the movable leg 3 is slightly bent inward, It is only necessary to rotate this, and it can be performed with the movable leg 3 connected to the side frame 2b.

  As described above, when the connecting member 6 and the movable leg 3 are rotated and fixed to the use state in which they are rearwardly horizontal, a tensile force acts on the entire panel member 4, and as shown in FIG. 1 and FIG. The lower side is stretched with a good appearance in a three-dimensional shape that bulges back in a convex curved shape, and the stand panel 1 can be made to stand on its own.

  An upward screw shaft 16 at the center of the circular floor contact plate 15 in the height adjustment adjuster 14 is screwed into a screw hole (not shown) formed at the lower end of the connecting member 5. As shown in FIG. 10, the screw shaft 16 also serves as a pivot shaft by press-fitting a spherical portion 16 a formed at the lower end portion thereof into a spherical concave hole 15 a on the upper surface of the circular floor contact plate 15. .

  As a result, the circular floor contact plate 15 can swing in multiple directions around the screw shaft 16, and the lower surface can always be in contact with the floor. Therefore, even if the floor surface is inclined or the stand panel 1 is tilted slightly rearward so that it does not easily fall forward, a gap is formed between the lower surface of the circular floor contact plate 15 and the floor surface. The stand panel 1 can be stably installed on the floor surface.

  The floor contact member 17 is screwed from below to the center of the movable leg 3 in the left-right direction, and the lower surface of the bag-like portion 4a of the panel material 4 inserted through the movable leg 3 is brought into contact with the floor. , It prevents the floor surface from getting dirty and damaged. The floor contact member 17 and the adjuster 14 may be omitted.

As described above, in the stand panel 1 of the first embodiment, the movable leg 3 is in a use state in which it is rearwardly horizontal and a non-use state in which the left and right side frames 2b face upward. Since it can be selectively fixed to the lower end of the side frame 2b, the form of the stand panel 1 can be easily changed between the use state and the non-use state.
Further, since the movable leg 3 and the side frame 2b are parallel to each other in the vertical direction when not in use, the front and rear (width) dimensions of the stand panel 1 are extremely large as shown in FIG. Get smaller. Therefore, as shown in FIG. 6, when the stand panel 1 is stored in a case 18 such as a cardboard box and packed with the adjuster 14 and the floor contact member 17 removed (they are separately packaged), the compact is compact. It can be packed in, and storage and transportation efficiency are improved.

  Further, the stand panel 1 has a simple structure with a small number of components and can be fixed by simply rotating the movable leg 3 connected in advance from a non-use state to a use state. Also, the assembly workability is very good.

FIG. 11 shows a second embodiment of the stand panel of the present invention.
In the second embodiment, a tension is applied to a bag-like panel material 19 made of a cloth having a lower end opened on a frame 2 having a downward U-shape similar to that of the first embodiment. In this way, the movable leg 3 similar to the above is left exposed from above.

When the stand panel is not used, as shown in FIG. 12, after removing the panel member 19, the movable leg 3 is fixed by rotating upward to a position parallel to the side frame 2b as in the above embodiment. Then, as indicated by a two-dot chain line, the panel material 19 is again covered on the frame 2 and the movable leg 3 from above.
Thereby, the front-back dimension of a stand panel becomes small and can be packed compactly similarly to 1st Embodiment. At this time, the adjuster 14 and the floor contact member 17 may be removed and packaged separately.

  In addition, when a cloth having a large stretchability is used for the panel material 19, the movable leg 3 is rotated upward with the panel material 19 mounted, and either one of the front and rear of the panel material 19 is used. The surface can also be recessed to make it unused.

The present invention is not limited to the above embodiment.
In the stand panel of the first embodiment, the bag-like portion 4a at the peripheral edge of the panel material 4 is inserted and stretched into the movable leg 3, but the upper frame 2a and the side portion of the frame 2 are stretched. The movable leg 3 may be exposed by being stretched only on the frame 2b.
Even in this case, the panel material 4 is made of a stretchable stretchable material, and when the movable leg 3 is not used, the panel material 4 is pressed and stretched in the front-rear direction and is recessed. The movable leg 3 can be positioned between the opposing surfaces of the both side frames 2b, and the front and rear dimensions of the stand panel when not in use are reduced.

  In the stand panels of the first and second embodiments, stretchable panel members 4 and 19 are stretched on the frame 2, and the movable leg 3 is used on the opposing surface at the lower end of the side frame 2b. It is assumed that it is attached so that it can be selectively fixed to an unused state. For example, a panel material such as a board or glass is attached to the upper part of a pair of left and right side frames, and both side frames The movable leg 3 as described above may be rotatably provided on the opposite surface of the lower end.
