Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is a movable wall installed on the floor with its upper end opened, and is used as a simple partition such as an office called a low partition. It relates to a movable partition wall.

[Prior Art] Conventionally, as a movable partition wall of this type, a pillar portion having an engaging hole is integrally provided at one joint end of a panel, and an engaging claw that bends downward is provided at the other end. It is known that the engaging claws are engaged with the engaging holes provided in the pillars of the adjacent panels to join the adjacent panels.

However, in such a conventional one, a plurality of panels can be sequentially joined by engaging the engaging claws with the engaging holes of the adjacent panels, and a wall having a required length can be formed. You can

[Problems to be Solved by the Invention] However, in such a configuration, if there is an error in the engagement depth of the engagement claws with respect to the engagement holes, the heights of one panel and the other panel are slightly different. It becomes a thing. Then, when a large number of panels are connected, the error is accumulated in the same direction. If this is forcibly corrected by an adjuster provided at the lower end of the pillar of each panel, the panel may be tilted in the left-right direction, which may cause distortion of a shape that cannot be ignored.

Further, in such a device, the specifications are completely different between the one in which the pillar portion is provided on the right side of the panel and the one in which the pillar portion is provided on the left side. Therefore, when the one surface side and the other surface side of the panel have different colors, there is also a problem that the degree of freedom when assembling or changing the specifications is greatly limited.

In order to eliminate such inconvenience, a pillar having engaging holes on the left and right joint surfaces and a height adjusting adjuster provided at the lower end, and a left and right joint surfaces formed separately from the pillar. And a panel provided with an engaging claw that bends downward,
It is conceivable that the engaging claws are engaged with the engaging holes so that adjacent panels are joined to each other through the columns.

However, in this type of movable partition wall, it is not uncommon for a bracket hole to be provided on the outward surface orthogonal to the joint surface of the pillar, and for the bracket hole to be used to hang a shelf board or desk top board, etc. . In particular, in recent offices and the like, heavy objects such as so-called OA equipment are often used by placing them on a desk top plate that is hooked to one side of such a movable partition wall, and a large fall on the pillar. Moments may act. In such a case, if sufficient connection strength is not secured at the joint part of the panel with the column interposed,
The upper edge of the movable partition wall formed by linearly connecting a plurality of panels corresponding to the inclination of each pillar is curved toward the load side. This type of movable partition wall is often a mode in which a large number of panels are connected in a straight line and orthogonal panels are attached only to both ends to prevent them from collapsing, so such a problem becomes a serious problem.

An object of the present invention is to solve such problems while simplifying the assembly.

[Means for Solving Problems] The present invention adopts the following configurations in order to achieve the above objects.

That is, the movable partition wall according to the present invention includes a pillar having engaging holes on the left and right joint surfaces, a bracket hole on the outward surface orthogonal to the joint surface, and an adjuster at the lower end, and the pillar. And a panel having separate left and right joint surfaces provided with engaging claws that are bent downward, the engaging claws engaging the engaging holes, and adjoining panels through the pillars. And a concave groove extending to the left and right along the panel joining direction, which is formed on the upper end surface of the adjacent panel and has an inner side surface that forms a tapered surface that expands upward, A connecting metal fitting, in which a taper portion bridged between the upper end surfaces and formed on the lower surface side is directly and closely engaged with the concave groove of each panel by ensuring an engaging length equal to or larger than the width dimension of the concave groove, Align one point on each end of the bracket. A fastener for fastening to the panel, a nut held near the upper end of the column, and a nut that is threaded into the nut through the central portion of the coupling fitting and is tightened to the coupling fitting in the pillar direction. It is characterized in that it is provided with a bolt to be pulled down to.

[Operation] According to the present invention, since the panel and the pillar are separately configured, the engaging claws of the panel engage with the engaging hole on the right side and the engaging hole on the left side of the pillar, respectively. It will be. for that reason,
Even if there is an error in the engagement depth between the engaging claw and the engaging hole, the error will not be accumulated in the same direction.

In addition, since the bolt is used to pull up the pillar toward the connecting metal fitting, in other words, the bolt is used to pull down the connecting fitting toward the pillar, so that the error is extremely small. It will be possible. That is, even if the pillar is pulled by the tightening force of the bolt toward the connecting fitting, if a gap is left between the upper surface of the pillar and the connecting fitting, the panel with the upper end abutting against the connecting fitting Will be pushed down relative to the pillar, and the engaging claw provided on the panel will be engaged to the deepest position of the engaging hole of the pillar. Therefore, the assembly dimensional error due to the insufficient engagement depth of the engagement claw with respect to the engagement hole can be reduced by an order of magnitude. On the other hand, as a result of pulling the pillar by the bolt, when the upper surface of the pillar comes into contact with the lower surface of the connecting fitting, both panels joined through the pillar are attached to the respective fasteners. It is positioned so as to come into close contact with the connecting fitting by the fastening force. Therefore, in this case as well, the upper ends of the adjacent panels are accurately aligned at the same level, and the engagement error of the engagement claws with respect to the engagement holes is not accumulated.

Further, with such a structure, the adjacent panels can be firmly connected to each other through the pillars. Therefore, the wall formed by connecting a plurality of panels is a rigid one piece as a whole. Therefore, only the pillars at both ends should be brought into contact with the floor to adjust the level, and then the adjuster provided at the lower end of the intermediate pillar should be adjusted so that these intermediate pillars also come into contact with the floor. Can also be adopted.

Further, in this case, the tapered portion of the connecting fitting is pushed between the tapered surfaces of the concave grooves of both panels adjacent to each other with the column interposed therebetween. Therefore, both panels are connected with their postures corrected by the wedge-like pushing action of the connecting fitting. In particular,
In the present invention, since the tapered portion of the connecting metal fitting is directly brought into close contact with the concave groove of each panel without interposing a cloth or the like, loosening is unlikely to occur in the tapered engaging portion, and moreover,
The tapered portion is engaged with the groove extending leftward and rightward along the panel joining direction while ensuring an engagement length equal to or larger than the width dimension of the groove, so that a highly rigid and reliable posture forcing function is provided. It is possible to exert the effect, and it is possible to firmly connect the upper end portions of the adjacent panels to each other via the connecting fitting.

Therefore, with such a movable partition wall, not only will all panels be flush with each other, but it will also be possible to attach the bracket to the bracket hole of the pillar and attach it to the desk top plate supported by the bracket. Even if a large load is applied, the problem that the column tilts toward the load side and the wall upper edge is curved does not occur. Therefore, even if many panels are linearly connected, it is possible to provide a movable partition wall having high rigidity and shape retention as a whole. Moreover, if it is such a connecting bracket,
If one end of each end is fastened to the upper end surface of the panel by using a fastener, the tapered portion of the connecting metal fitting is pushed between the tapered surfaces of the concave groove of the panel and the above-described posture configuring function is exerted. To be done. Therefore, contrary to the conventional wisdom, it is possible to construct a linear partition wall without distortion in the thickness direction using a small number of fasteners. That is, in order to bridge a normal plate-like connecting member between the upper end surfaces of adjacent panels so that the joint portion of those panels is not deformed in the thickness direction, at least two positions of each end of the connecting member are respectively Since it is necessary to fix the panel to the corresponding panel, four or more fasteners such as bolts are required.
It is possible to connect the panels to each other in an appropriate posture correction state by using only one fastener on each of the left and right sides.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 to 6.

This movable partition wall has a pillar 1 in which the left and right joint surfaces 1a and 1b are provided with engaging holes 2, respectively, and a pillar 1 that is formed separately from the pillar 1 and has engaging claws 4 on the left and right joint surfaces 3a and 3b. The panel 3 is provided, and the engaging claws 4 are engaged with the engaging holes 2 so that adjacent panels 3 are joined to each other via the pillar 1.

As shown in FIGS. 1 and 2, the pillar 1 is a prismatic pipe having an adjuster 11 at its lower end, and a plurality of engagement holes 2 are vertically provided in the left and right joint surfaces 1a and 1b. Are drilled at intervals. As shown in FIG. 2, each engagement hole 2 has an inverted trapezoidal shape in which the length dimension of the lower edge opening edge 21 is slightly shorter than the length dimension of the upper edge opening edge 22,
A through hole is formed to connect the inside and the outside of the pillar 1. Also, the fourth
As shown in FIGS. 5 and 5, the joint surface 1 of the pillar 1 is shown.
A plurality of bracket holes 15 are formed at a predetermined pitch in the up-down direction in the central portion in the left-right direction of the outward surfaces 1m, 1n orthogonal to a and 1b.

As shown in FIGS. 1 and 3 to 5, the panel 3 has an aluminum upper frame member 31, a side frame member 32, and a lower frame member 33 joined in a frame shape, and has face plates 34 on both sides thereof. Is attached using an epoxy adhesive or the like, and a core material 35 is housed inside. The left and right side frame members 32 have wide outer grooves 32a on the outer surfaces to be the joint surfaces 1a and 1b of the panel 3.
And a columnar pipe having a narrow inner groove 32b, and the pillar 1 is fitted between the inner surfaces of the outer groove 32a. Then, the engaging claws 4 are fixedly provided in the portions corresponding to the engaging holes 2 in the inner groove 32b. The engaging claw 4 includes a board 41 fixed to the bottom surface of the inner groove 32b, and a pair of claw bodies 42 extending outward from both side edges of the board 41. The claw body 42 has an inverted L shape that bends downward. The distance between the outer surfaces of the pair of claw bodies 42 formed from each substrate 41 is set to be the same as the length dimension of the lower end opening edge 21 of the engagement hole 2.

Then, as shown in FIGS. 4 and 6, a connecting fitting 5 is bridged between the upper end surfaces 3c of the adjacent panels 3, and each end 5a of the connecting fitting 5 is connected to a single fastener, for example, The upper frame member 31 of the corresponding panel 3 using one bolt 6
The pillar 1 is moved in the direction of the connecting metal fitting 5 by screwing a bolt 7 penetrating through the center of the connecting metal fitting 5 into a nut 8 held near the upper end of the pillar 1 and tightening it. I'm trying to attract.

As shown in FIG. 3 and FIG. 4, the connecting fitting 5 is made of a strip having a U-shaped cross section, and has a V-shaped bulge at the center of the bottom wall thereof. The lower surface side of the portion 51 is a tapered portion 52. On the other hand, a concave groove 36 having a V-shaped cross section is formed on the upper surface of the upper frame member 31 of the panel 3, and an inner side surface of the concave groove 36 is formed as a tapered surface 37 expanding upward. Then, the taper portion 52 is engaged with the concave groove 36 by bridging the connecting fitting 5 between the upper end surfaces 3c of the panel 3. Connection fitting 5
The bolts 6 for fastening the panel 3 to the panels 3 are screwed into the plate nuts 38 held inside the upper frame member 31. As clearly shown in the drawing, the groove 36 is formed so as to extend to the left and right along the panel joining direction, and the engagement length of the tapered portion 52 of the connecting fitting 5 with the groove 36 of each panel 3 is determined. L is the groove 36
It is set to be larger than the width dimension W of. The tapered portion 52 of each connecting fitting 5 is directly and closely engaged with the tapered surface 37 of the groove 36, as shown in FIGS. 3 and 4.

Reference numeral 91 denotes an upper end cover that covers the upper end surface of the panel 3, and 92
Is a side edge cover that covers the opposite panel side of the endmost pillar 1. Further, 93 is a skirting board that covers a space formed between the lower end of each panel 3 and the floor surface 10. The skirting board 93 is detachably attached to the pillar 1 by using a claw 93a.

With such a configuration, since the pillar 1 and the panel 3 are separate bodies, the pillar 1 and the panel 3 can be formed in a bilaterally symmetrical shape. for that reason,
The versatility is higher than that of the conventional panel whose left and right are asymmetrical. For example, even if the color of the one side of the panel 3 is different from that of the other side, the front and back of one type of panel 3 can be freely selected and desired. It is possible to assemble in the form of.

Further, when the pillar 1 and the panel 3 are completely separated from each other and the engaging claws 4 of the panels 3 bent downward are engaged with the engaging holes 2 of the pillar 1, The phenomenon that the assembly error due to the insufficient engagement depth of the engagement claws 4 accumulates in the same direction as the number of panels increases does not occur. In particular,
In this structure, the pillar 1 is pulled to the connecting fitting 5 by the tension of the bolt 7. As a result, the connecting fitting 5 and the pillar 1
When a gap is left between the upper surface 1c and the upper surface 1c, the panel 3 whose upper end surface 3c is pressed by the connecting metal fitting 5 is pushed down relative to the pillar 1, and the panel 3 is provided. The engaging claw 4 is engaged even at the deepest position of the engaging hole 2. That is, the bent portion of the claw body 42 of the engaging claw 4 comes into contact with the lower end opening edge 21 of the engaging hole 2. Therefore, the assembling dimensional error due to the insufficient engagement of the engaging claw 4 with the engaging hole 2 can be minimized. On the other hand, when the upper surface 1c of the pillar 1 comes into contact with the lower surface of the connecting fitting 5 as a result of pulling the pillar 1 toward the connecting fitting 5 with the bolt 7, the joining is performed via the pillar 1. Both panels 3 are positioned so as to be in close contact with the connecting fitting 5 by the fastening force of each bolt 6. Therefore, in this case as well, the upper ends of the adjacent panels 3 are accurately aligned at the same level, and the accumulation of the engagement error of the engagement claws 4 with respect to the engagement holes 2 is prevented.

Moreover, if it is such a thing, the adjacent panels 3 can be firmly connected via the pillar 1. Therefore, the wall itself configured by connecting the plurality of panels 3 together becomes a highly rigid integrated body as a whole. Therefore, the pillars 1 at both ends
Only the adjuster 11 of the intermediate column 1 is brought into contact with the floor surface 10 to adjust the level, and then the intermediate column 1 is adjusted to the floor surface 10 by adjusting the adjuster 11 provided at the lower end of the intermediate column 1.
It is also possible to adopt an assembling mode in which the device is loaded on. Therefore, as compared with the case where the adjusters of a plurality of columns are adjusted by trial and error to adjust the level, the assembly and installation work can be significantly speeded up.

Further, in this one, the connecting metal fitting 5 having the V-shaped taper portion 52 is pushed between the tapered surfaces 37 of the concave grooves 36 of both the panels 3 which are also V-shaped, and the column 1 is pulled upward. For example, the connecting fitting 5 and the panel 3 are brought into close contact with each other. Therefore, both panels 3 which are adjacent to each other with the pillar 1 in between are connected in a state in which the posture is corrected by the wedge-like pushing action of the connecting fitting 5. Therefore,
As long as the connecting fitting 5 and the concave groove 36 of each panel 3 are linearly manufactured, all the panels 3 are flush with each other. Therefore, the appearance is very good, and for example, it is possible to obtain an excellent partition wall in which the entrance and exit of the panel 3 is not noticeable even when the light is emitted at a shallow angle for performing the indirect illumination. it can. And if it is such a thing, since the taper part 52 of the said connection metal fitting 5 has penetrated into the recessed groove 36 of each panel 3,
Each end 5a of the connecting fitting 5 has a single bolt 6
Despite being fixed to panel 3 by
The connection strength is extremely high, and in particular, it is difficult for the panel 3 to be deformed even when an external force acts in the thickness direction. That is, to secure the strength in the thickness direction by connecting the upper end surfaces of both panels with a normal flat plate-like connecting fitting, as described above, four or more bolts are required. Since the tapered portion 52 of the connecting fitting 5 is joined and tightened between the tapered surfaces 37 of the panel 3, the strength in the thickness direction can be increased simply by tightening each end 5a of the connecting fitting 5 with one bolt 6. Can be demonstrated. Therefore, with such a structure, not only can the number of parts be reduced, but also the number of bolt tightening operations during assembly can be reduced. Therefore, when assembling a long partition wall, the number of assembling steps can be significantly reduced.

In addition, the shape of the connecting fitting may be, for example, as shown in FIGS. That is, the connecting fitting 105 shown in FIG. 7 is formed by bending the center of a flat plate into a V shape to form a tapered portion 152.
Are engaged between the tapered surfaces 137 of the panel 103. In the connecting fitting 205 shown in FIG. 8, both side edges of the flat plate are bent obliquely upward, and the lower surface thereof is tapered 252.
The taper portion 252 is attached to the panel 2
The taper surfaces 237 of No. 03 are engaged with each other.
The connecting fitting 305 shown in FIG. 9 is one in which a thick portion is provided on the lower surface of a flat plate, and the tapered portion 352 is formed by inclining both sides of the thick portion.
No. 03 taper surface 337 is engaged.

EFFECTS OF THE INVENTION Since the present invention is configured as described above, it is possible to effectively eliminate the inconvenience that distortions occur in the overall shape due to the accumulation of engagement errors between the engagement claws and the engagement holes. As a result, it is possible to secure the assembling accuracy, and it is possible to obtain an effect that the rigidity of the entire wall is improved and the level can be easily adjusted.

In addition, since the tapered part of the connecting metal fitting is pushed between the tapered surfaces of the panel and tightened, each panel can be connected flush with each other, and the appearance of the entire wall can be further improved and the thickness can be improved. Even if an external force acts in the direction, it is possible to construct a strong wall that does not largely bend in the direction. In particular, in the present invention,
Since the taper part of the connecting fitting is secured in the groove of each panel with a sufficient engagement length and is directly and closely engaged,
It is possible to cause the connecting fitting to exert a reliable posture-forced function, and it is possible to firmly connect the upper end portions of the adjacent panels to each other via the connecting fitting. Therefore, not only all the panels are flush with each other, but also when the bracket is hooked on the pillar bracket hole and a large load is applied to the desk top plate etc. supported by the bracket, the pillar is not It does not cause a problem that the upper edge of the wall is curved by inclining to the load side. Therefore, even if many panels are linearly connected, it is possible to provide a movable partition wall having high rigidity and shape retention as a whole. Moreover, according to the configuration of the present invention, this effect can be obtained only by fixing one fastening member on each of the left and right sides and fixing the central bolt. Therefore, a sturdy partition wall can be quickly assembled without any trouble.

In addition, since the pillars and the panels can be made bilaterally symmetrical, there is an effect that the degree of freedom in arrangement and assembly can be greatly expanded.
