Description

  The present invention relates to a partition for partitioning an indoor space, and more particularly, to a self-supporting partition that is easy to assemble and disassemble and is not easily toppled.

  As a means for easily partitioning an indoor space, a self-supporting partition is well known. This is composed of a flat panel having a predetermined height, a support leg that is connected to the lower end of the panel and vertically supports the panel, and a connecting means that connects the panels, and is fixed to a wall surface or a floor surface. It is possible to arrange a plurality of panels in a desired layout without changing the layout.

  Such partition is preferably used in, for example, Japanese Patent No. 4291869 because it can be easily assembled and disassembled when used in an office or factory where layout changes are performed at a relatively high frequency. As described above, there is known one that employs connection means for facilitating the connection and separation procedures between panels.

  However, in the partition described in this patent document, a ridge formed on the second vertical frame of the adjacent panel is inserted into the concave formed on the first vertical frame of the panel by the connecting means, and the frame is formed on the upper end side thereof. Since the cap is connected and connected, and it has a fine and complicated configuration, the labor involved in the connection is not fully eliminated, and the manufacturing cost tends to increase.

  In addition, in the conventional self-supporting partition including this partition, the means for supporting the panel in a vertical state is a support leg arranged on the floor surface, so that it does not have a bent portion or has a large linear portion. The stability (hardness of falling) of the panel is proportional to the weight of the support leg and the size in the direction perpendicular to the panel. For this reason, if the stability of the panel is emphasized, the weight and size of the support legs will increase, and in addition to being disturbed after installation, the safety will be impaired, and the portability will also be reduced, making assembly and disassembly work easier It leads to the loss of sex.

Japanese Patent No. 4291869

  An object of the present invention is to solve the above problems, and it is an object of the present invention to provide a self-supporting partition that is easy to assemble and disassemble and has excellent stability and safety.

  Accordingly, the present invention provides a self-supporting partition including a flat panel in a front view and a connecting means for connecting adjacent panels, and a weight is provided on a lower end side of the panel over a predetermined range in the width direction. A member is attached or built in and integrated with the panel, and the weight of the portion from the lower end of the panel to 1/20 of the height occupies 25% or more of the panel weight including the weight member. It was supposed to be.

  In this way, by providing a weight member on the lower end side of the panel in the self-supporting partition and significantly reducing the center of gravity of the panel, it becomes easier to stabilize against the urging force that tilts the panel, and the panel is tilted. However, the low center of gravity position makes it easy to return to the original vertical state by itself.

  Also, in this partition, the panel has a plurality of prismatic legs that are suspended downward from both ends of the lower end surface, and the side end sides are arranged close to each other where the panels are connected to each other. If the legs of the panel are fixed and connected to each other by being fitted into the connecting means from above, the lower ends of the continuous panels can be easily connected It becomes.

  In this partition, the connecting means includes a metal flat base portion arranged in close contact with the floor surface, and a plate material standing upright on the upper surface side of the base portion. If it is characterized in that it includes a support leg composed of a panel support part that sandwiches and supports the panel by inserting the part from above, the assembly work is facilitated. In this case, the panel support part A pin is interposed at a predetermined position on the inner side of the plate so that the inner surface side of the opposed plate member is passed in a right angle direction, and the leg inserted from above is held between the pin and a predetermined surface facing the peripheral surface. If the leg sandwiching means is formed, and the leg sandwiching means restricts the movement of the panel in the width direction and resists the movement of the leg in the removal direction, the simple structure can be obtained. Even with the configuration panel and support legs Connection-separation work is very easy, and, since the base portion of the support legs of the metal in close contact with the floor surface is further lowered center of gravity of the whole, and is excellent in more stability.

  Further, in the case where the leg sandwiching means is provided, the support leg of the part where the panels are linearly connected is the inner part of one panel support part, and the two pins are at the same height with a predetermined interval. If the two legs are inserted and sandwiched between the pair of pins with the outer surfaces in close contact with each other, the panel support portion of the support leg is used. It also serves as a panel connecting means, and a more robust connection state can be realized without increasing the time and labor of panel connection work.

  Furthermore, in the partition provided with the above-described support legs, the base portion has a foot plate extending at least in the width direction of the panel from the lower position of the panel support portion, and has a long side with a rectangular shape in plan view. As a whole, the weight plate whose length is equal to the width of the panel is placed so that both ends of the weight plate are placed on the upper surface of the foot plate so as to pass between the connecting means on both ends of the panel. If the center of gravity is realized, the weight of the panel itself can be set lighter, and the weight member can be arranged very easily.

  Alternatively, in the partition having the above-described support legs, if the base portion is circular in plan view, the floor surface is not easily damaged due to the absence of corner portions, and the outside It is easy to ensure the safety of the user in that the edge side is not easily caught.

  In addition, in the above-described partition, if the connecting means includes a connecting bracket for connecting the upper corners of the aligned panels, not only the lower end side of the panel but also the upper end side. However, since it is connected and fixed, the stability is further improved.

  According to the present invention in which a weight member is provided on the lower end side of the panel and the center of gravity is remarkably lowered, assembly and disassembly are facilitated with a simple configuration, and stability and safety are excellent.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  FIG. 1: has shown the front view of the linear part of the partition which is the 1st Embodiment in this invention. In the present embodiment, one of the connecting means for connecting the panels 2A, 2A, 2A,... That are square in front view and the lower ends of the connecting portions of the adjacent panels 2A, 2A in a state of being arranged on the floor surface. , And metal support legs 3A, 3A, 3A,... That vertically support at least a pair of panels 2A, and a connecting bracket 5 as a connecting means for connecting upper ends of connecting portions of adjacent panels 2A, 2A. , 5, 5,... Constitute a self-supporting partition.

  The structure of the panel 2A described above with reference to FIG. 2 will be described in detail. The panel 2A used in the present embodiment is a flat plate portion having a smooth surface with a vertically rectangular shape in front view formed by forming a plate of wood. Columnar portions 21 and 22 made of vertically long wooden members are provided on the left and right end sides of 20A, and the leg portions 21a and 22a are portions where these columnar portions 21 and 22 slightly protrude downward from the line of the bottom surface of the flat plate portion 20A. Is configured. The size of the flat plate portion 20A is assumed to be about 1000 mm in width and about 1000 to 1800 mm in the case of an office partition, for example, and the length of the legs 21a and 22a in this case is about 20 to 50 mm. Is preferred.

  In addition, on the lower end side of the flat plate portion 20A, as shown by broken lines, weight members 25, 26 having a horizontal prism shape are built in over a range that occupies most of the width direction. The weight of the portion from the body 21a, 22a tip surface) to 1/20 of the height of the panel 2A occupies 25% or more of the total weight of the panel 2A, and this is a characteristic part of the present invention. . This is because the weight member was provided on the lower end side of the panel under various conditions, and as a result, the panel was excellent in balance between stability (tilt resistance) and portability.

  For example, the flat plate portion 20A has a width of 920 mm, a height of 1475 mm, a length of the legs 21a and 22a of 25 mm, a wooden portion excluding the weight members 25 and 26 has a weight of 8 kg, and a prismatic iron material having a short side of 20 × 20 mm. (2 kg) When the weight members 25 and 26 (4 kg in total) stacked in the vertical direction in the horizontal direction are installed with the depth of 40 mm inserted from the lower surface of the flat plate portion 20A, the panel 2A from the front end surface of the legs 21a and 22a The total weight is 12 kg with a height of 1500 mm, but the weight of the part up to 75 mm, which is 1/20 of the height, occupies 25% or more of the total. In this case, the center of gravity of the panel 2A is remarkably low at about 500 mm from its lower end, so that it becomes easy to maintain a vertical state against the urging force in the direction of tilting it, and it is extremely stable and safe. It will be excellent.

  FIG. 3 shows the details of the support / connection portions of the continuous panels 2A, 2A by the support legs 3A in the partition of FIG. The support leg 3A stands with a base 30 made of a thin metal plate arranged with its back surface in close contact with the floor, and metal plates 31a and 31b (see FIG. 4) facing each other on the upper surface of the base 30. It is provided with a panel support part 31 that sandwiches and supports the lower end side corners of the panels 2A and 2A by inserting them from above, and one panel is arranged at a part connecting the panels 2A and 2A in a straight line. These are connected and supported.

  On the both ends of the inside of the panel support portion 31, at a height position of about one third from the bottom, a metal round bar-like pin 311 is provided so that the inner surfaces of the opposing plate members 31 a and 31 b are passed in a right angle direction. 311 are arranged side by side, and the pair of pins 311 and 311 constitute a leg sandwiching means 310, and the legs 22a and 21a of the panels 2A and 2A arranged in a straight line are arranged. By inserting them in a back-to-back state in which the outer surfaces are in close contact with each other, they are held while being sandwiched.

  In the present embodiment, the pins 311 and 311 are in close contact with the inner corner portions formed by the bottom surfaces of the flat plate portions 20A and 20A and the inner surfaces of the legs 22a and 21a that intersect with each other at right angles. In this state, the legs 22a and 21a are strongly sandwiched from the left and right while the bottom surfaces are in contact with the top surface of the base portion 30. Therefore, the movement of the panels 2A, 2A in the width direction is restricted, and the panel support portion 31 of the support leg 3A is maintained while maintaining the support / connection state against the movement of the legs 22a, 21a in the removal direction. By serving as a part of the connection means of the panels 2A and 2A, it becomes possible to realize a firm connection state without increasing the labor of the connection work.

  For example, when the weight of the support leg 3A is 1.2 kg, the diameter of the base part 30 is 250 mm, and the height of the pin 311 from the upper surface of the base part 30 is 25 mm, the center of gravity is connected and supported to the panel 2A. The position is 400 mm from the lower end, which is even lower. For this reason, in combination with the support force by the width (250 mm) of the panel 2A in the thickness direction of the base unit 30, even if it is tilted once up to a predetermined level of tilting angle, it is in a vertical state as in the case of rising up It also has the feature of returning to its own, and exhibits excellent strength (earthquake resistance) against earthquake shaking.

  4 shows a cross-sectional view taken along the line XX of FIG. 3, but the iron weight members 25 and 26 in the shape of a horizontal prism are vertically arranged at a predetermined depth position from the lower surface of the flat plate portion 20A of the panel 2A. It is in a state of being stacked and decorated. The weight members 25 and 26 may be fixed in a groove formed on the bottom surface of the flat plate portion 20A by fixing means such as screws from below, and thereby separate from the flat plate portion 20A at a stage before assembly. As a result, the portability of the panel 2A becomes extremely good. Needless to say, one weight member in which these two weight members 25 and 26 are integrated may be used.

  FIG. 5A shows a plan view of the support leg 3A, but the base portion 30 is circular in plan view and has no corners. For this reason, it is difficult to damage the floor surface to be arranged, and the outer edge side is not easily caught by a person or an object moving nearby, which is excellent in terms of safety. Further, the support leg 3A has a square base portion having the same size as the diameter and the length of one side where the size in the direction perpendicular to the width direction of the panel 2A by the base portion 30 corresponds to the diameter. Panel support and stability equivalent to the support legs can be achieved.

  FIG. 5B shows the support leg 3B used on the end side of the panel 2A on the end side in the partition of the present embodiment. A plate member 32a is erected on the upper surface of the base portion 30 that is circular in plan view, and a single pin 311 is disposed across the opening side of the base member 32a so as to be the end portion of the panel 2A. It is a panel support part 32 that inserts and supports a corner part, and constitutes a leg clamping means 320 that inserts and clamps either the leg 21a or the leg 22a.

  FIG. 6A shows a support leg 3C that supports the panels 2A and 2A while connecting them at the bent connection portion in the partition of the present embodiment. In this case, the panel support portion 33 erected on the upper surface of the base portion 30 having the same configuration as described above is a combination of plate members 33a and 33b bent at a right angle in plan view, and pins 311 are disposed on both opening sides. Thus, the panels 2A and 2A are supported while being connected in a perpendicular direction. In addition, by inserting a prismatic interposing member (not shown) into a portion defined by a one-dot chain line at a portion bent at a right angle inside the panel support portion 33, a leg sandwiching means 330 is configured, and the panels 2A and 2A are formed. It comes to be fixed firmly.

  FIG. 6B shows a support leg 3D that supports the panel 2A, 2A, 2A while connecting them at the T-shaped connecting portion in the partition of the present embodiment. In this case, the panel support portion 34 erected on the upper surface of the base portion 30 having the same configuration as described above has a T-shaped inner side by a combination of a plate material 34a having a linear shape in plan view and plate materials 34b and 34c bent at a right angle in plan view. The part 3 is comprised, and the pin 311 is each arrange | positioned at three opening parts, and it supports it, connecting panel 2A, 2A, 2A in T shape. As described above, the leg sandwiching means 340 is formed by inserting a prismatic interposing member (not shown) in a portion defined by a one-dot chain line at the center crossing portion inside the panel support portion 34. is there.

  By the way, in the partition, the bent part and the part where the panels are connected to each other in a T shape or cross shape, the panel constituting this can be self-supported even if there is no support leg, and the straight part following this part is short In this case, the straight part panel is also self-supporting without supporting legs.

  Therefore, as shown in FIG. 7, at the connecting portion of the self-supporting panels 2A and 2A, the lower end side corner portion is connected using the supporting leg 4 having a shape obtained by reducing the base portion 30 of the supporting leg 3A described above. You may do it. That is, as shown in the enlarged view of FIG. 8 and the cross-sectional view along the YY line, the support leg 4 is formed by bending a metal plate, and a base that is reduced instead of the disk-like base 30. The bottom plate 41c is a part that comes into contact with the floor surface as a part, and the vertical plates 41a and 41b are erected from the long side edge part so as to face each other, and the pins 411 and 411 are arranged sideways like the support legs 3A. These are arranged side by side, and these constitute the leg sandwiching means 410.

  If this support leg 4 is used, the linear connection part of the panel 2A which can stand independently can be firmly connected by using together with the connection metal fitting 5 used for the upper end side. In addition, in the bendable portion and the T-shaped connecting portion that can stand independently, the base portions 30 of the supporting legs 3C and 3D shown in FIGS. What is necessary is just to use the connection metal fitting of a structure.

  FIG. 10 shows a panel 2B as an application example of the panel 2A described above. In this example, instead of installing the iron weight members 25 and 26 from the bottom surface of the flat plate portion 20A to a predetermined depth, the flat plate portion 20B is formed by attaching a weight member 27 made of a prismatic stone material oriented laterally on the bottom surface side. It is characterized by the point. The weight member 27 may have a dimension exceeding the thickness of the panel portion in order to secure the same weight as the weight members 25 and 26, and the weight member 27 having a stone texture is the lower end of the panel 2B. A design accent is formed by being exposed to the side and protruding in the panel thickness direction.

  FIG. 11 shows a support leg 3E which is an application example of the support leg 4 and the weight members 25 and 26 shown in FIG. 8, and a weight plate 28 used in combination therewith. As in the case of FIG. 8, as in the case where the panel itself is self-supporting, such as a bent part, and the vicinity thereof, the panel is simply connected at a place where the size of the flat part of the support leg is unnecessary, The aim is to achieve a lower center of gravity.

  The support leg 3E is substantially the same in structure as the support leg 4, but the width of the base part 37 in the minor axis direction is equal to the width of the panel support part 35 in the minor axis direction. It differs in that it has foot plates 37a and 37b extending from the lower position of the support portion 35 in the width direction of the panel. On the other hand, the weight plate 28 used in combination is made of a material having a large specific gravity, such as iron, having a substantially rectangular shape in plan view, the length of the long side being substantially equal to the width of the panel, and the length of the short side being the thickness of the panel. And a connecting portion 28b, 28c made of a U-shaped fitting in plan view for connecting to the support legs 3E attached to both ends thereof.

  These usage methods will be described with reference to FIG. 12. First, as shown in the plan view of FIG. 12A, a plurality of support legs 3E are roughly spaced at intervals of about the width of the panel on the assumed line of the floor where the partition is provided. To place. Next, as shown in FIG. (B), both ends are placed on the foot plates 37a and 37b while engaging the concave portions of the connecting portions 28b and 28c on the short side of the panel support portion 35 of each support leg 3E. The weight plate 28 is placed so as to be placed, positioning and weight setting are completed, and then the lower end side corner portion of each panel indicated by the alternate long and short dash line as shown in the front view of FIG. The installation work is completed by inserting from above.

  As a result, the weight plate 28 is connected to the lower end side of the panel via the support legs 3E, thereby further reducing the center of gravity of the panel. In addition, since the base portion 37 does not protrude greatly from the width in the panel thickness direction, it is difficult to disturb the use, and the distance between the support legs 3E and 3E is equal to the width L of the panel only by arranging this. This also functions as a ruler for positioning so that the panel installation work can be accurately completed in a short time.

  FIG. 13A shows a plan view of the support leg 3E, and the other figures show variations of the support leg 3E in the same manner as those shown in FIGS. 5 and 6, and FIG. The support leg 3F used, FIG. (C) is a support leg 3G used for the bent part, and (D) is a plan view of the support leg 3H used when the panel is connected at a right angle to the linear connecting portion. Yes. In addition, in the case of FIGS. (C) and (D), in the bent portion / joint portion that gives the panel itself independence, in addition to being able to be easily connected, it is useful in that the center of gravity can be lowered very easily. It becomes. Note that the configuration shown in FIG. 4D may be a support leg having a cross shape in plan view that connects the panels in a cross shape.

  FIG. 14 shows a support leg 3J as a modification of the support leg 3E of FIG. In the support leg 3J, a pair of screw holes 36a, 36a are formed in the upper center position of the panel support portion 36 instead of the pair of pins 411, 411 constituting the leg sandwiching means in the support leg 3E. An auxiliary plate 39 having a screw hole 39a in the center of the plate and a pair of sandwiching plates 39b and 39c bent and projected in the perpendicular direction on the upper side is provided with two closely attached legs of the sandwiching plates 39b and 39c. The bolts 100 are mounted so as to be sandwiched therebetween, and the bolts 100 are inserted into the screw holes 39 a, 36 a, 36 a and screwed into the nuts 200 to be fixed.

  In this example, a notch for allowing the bolt 100 to pass is formed in the leg side end surface of the panel. By fixing the auxiliary plate 39 in a state where the two legs are inserted into the panel support portion 36, 2 In addition to being accurately positioned by sandwiching the leg of the book from the left and right by the sandwiching plates 39b and 39c, the panel is less likely to be loose after fixing. Although not shown in the drawings, if the notch having a predetermined shape is formed in the panel support portion 36 and a claw portion that engages with this is provided on the leg body side, and these are engaged when connected, the auxiliary plate 39 Even if the bolt 100 is omitted, a firm connection is realized. It should be noted that the above-described characteristic portions can be applied to all of the above-described support legs that are connected and supported in a state in which two panel legs are in close contact with each other.

  The partition shown in FIG. 1 was actually created and tested for its ability to tilt (seismic resistance). The panel has a height of 1500 mm, a width of 900 mm, a panel body weight of 8 kg, a weight of 4 kg, a total panel weight of 12 kg, a support leg weight of 1.2 kg, a base part diameter of 250 mm, and two support legs for each panel. Then, while pushing the upper side of the panel with the hand, the tilt angle immediately before falling down was measured.

(Result) It did not fall down to the state shown in the photograph of FIG. The tilt angle at this time was 20 degrees. On the other hand, in the control example in which other conditions were the same in the state where the weight was not inserted, the body fell about 14 degrees. From this experimental result, it was found that the partition according to the present embodiment has high anti-tilt ability and excellent stability.

  As described above, the partition according to the present embodiment has an extremely simple configuration and a small number of parts, and thus has an advantage of low manufacturing cost. In addition, since the structure of the portion that connects and supports the panels 2A is extremely simple and easy to handle, the assembling / disassembling work can be performed very easily. In addition to this, by providing a weight member on the lower end side of the panel, the position of the center of gravity is remarkably lowered and it is difficult to tilt, which is extremely excellent in stability and safety.

  As described above, the self-supporting partition can be easily assembled and disassembled according to the present invention, but has excellent stability and safety.
