Description

[Detailed description of the invention] [Industrial field of application] The invention is a movable wall that is installed on the floor with the top end open, and is called a low partition and is used for simple partitions in offices, etc. This relates to a movable partition wall.

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

However, in such conventional devices, by engaging the engaging claw with the engaging hole of the adjacent panel,
Multiple panels can be joined one after the other to form a wall of the required length.

Note that this type of partition wall is required to have various specifications with different heights, and conventional partition walls meet this demand by preparing a variety of panels with different heights.

[Problems to be solved by the invention] However, with the structure described above, if there is an error in the engagement depth of the engagement claw with the engagement hole, the height of one panel and the other panel may be slightly different. It will be different. When a large number of panels are connected, the errors will accumulate in the same direction.
If this is forcibly corrected using the adjuster provided at the lower end of the pillar portion of each panel, problems such as tilting of the panel in the left-right direction may occur, which may result in non-negligible distortion of the shape.

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

Furthermore, if panels of various heights were prepared to accommodate the increasing number of height specifications for partition walls, the number of panel types would increase significantly, making production equipment more complex and This tends to lead to an increase in man-hours. Moreover, with such a device, once it is selected and used, its height cannot be changed. Therefore, if a change in height is unavoidable, the entire partition wall must be replaced with a new one, which is uneconomical.

The present invention aims to eliminate all such problems.

[Means for Solving the Problems] In order to achieve the above objectives, the present invention employs the following configuration.

That is, the movable partition wall according to the present invention includes a main pillar having engagement holes provided on the left and right joint surfaces, respectively;
A main panel is constructed separately from the main column and has engaging claws bent downward on the left and right joining surfaces, and a main panel is removably connected to the upper end of the main column and engages the left and right joining surfaces, respectively. An auxiliary column with a matching hole,
an auxiliary panel that is removably mounted on the upper end of the main panel and has engaging claws bent downward on the left and right joining surfaces, the engaging claws being engaged with the engaging holes, Adjacent main panels are connected to each other through the main pillar, and adjacent auxiliary panels are connected to each other through the auxiliary pillar, and the upper end surfaces of the adjacent auxiliary panels are removably attached. A bridged connecting fitting, a nut held near the upper end of the main column, and a nut that penetrates through the center of the connecting fitting and is screwed onto the nut, and its tightening force connects the main column and the auxiliary column. It is characterized by comprising a bolt that is pulled up in the direction of the metal fitting.

[Function] According to this configuration, since the panel and the column are constructed separately, the engagement claws of the panel engage equally with the engagement hole on the right side and the engagement hole on the left side of the column. I will do it. Therefore, even if there is an error in the engagement depth between the engagement claw and the engagement hole, the error will not accumulate in the same direction.

Furthermore, since the main column and the auxiliary column are pulled up in the direction of the connecting fittings using bolts, the error itself can be made very small. In other words, when the main column is pulled toward the connecting fittings by the tightening force of the bolts, the main panel and auxiliary panel, whose upper ends are held down by the connecting fittings, are pushed down relative to the main column and auxiliary columns. As a result, the engaging claws provided on each panel engage with the deepest position of the engaging hole of each column. Therefore, the assembly dimensional error caused by insufficient engagement depth of the engagement claw with the engagement hole can be reduced by an order of magnitude.

Further, with such a structure, adjacent main panels and auxiliary panels can be firmly connected via the main pillar and the auxiliary pillar. Therefore, the entire wall constructed by connecting a plurality of main panels and auxiliary panels becomes a rigid integral body as a whole. Therefore, the level is adjusted by bringing only the pillars at both ends into contact with the floor, and then by adjusting the adjuster etc. installed at the lower end of the middle pillar, the middle pillars are also brought into contact with the floor. It is also possible to adopt a different assembly method.

Since these main panels and auxiliary panels can be shaped laterally symmetrically, the front and back sides can be freely selected and used.

Moreover, if it becomes necessary to reduce the height of the entire wall, the auxiliary columns and auxiliary panels can be removed from the main columns and the main panels, and the connecting fittings can be bridged between the upper ends of the main panels. This requirement can be met by threading and tightening a bolt passed through the center of the connecting fitting into a nut provided near the upper end of the main column. On the other hand, if it is necessary to increase the height of the entire wall, install more auxiliary columns on top of the auxiliary columns, place another auxiliary panel on top of the auxiliary panel, and increase the height of the topmost auxiliary panel. This requirement can also be met by bridging a connecting fitting between the upper end surfaces and tightening a bolt passed through the center of the connecting fitting to a nut provided on the main pillar.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

The distance between the outer surfaces of the pair of pawl bodies 42 drilled from 1 is set to be the same as the length of the lower opening edge 21 of the engagement hole 2.

The auxiliary panel 103 includes an upper frame member 131, a side frame member 132, and a lower frame member 13 also made of aluminum.
3 are joined into a frame shape, and a face plate 134 is attached to both sides of the frame using an epoxy adhesive or the like, and a core material 135 is housed inside. The left and right side frame members 132 have a wide outer groove 132a and a narrow inner groove 132b like the side frame member 32, and the auxiliary column 101 is formed between the inner surfaces of the outer groove 132a. are designed to fit together. Further, an engaging claw 104 having a base plate 141 and a claw body 142, similar to the engaging claw 4, is fixedly provided at a portion corresponding to the engaging hole 102 in the inner groove 132b.

As shown in FIGS. 2 to 4 and 6, the upper end surface 103 of the adjacent auxiliary panel 103
A connecting metal fitting 5 is bridged between the connecting metal fittings 5 and c, and each end portion 5a of this connecting metal fitting 5 is fixed to the upper frame member 131 of the corresponding auxiliary panel 103 using two bolts 6, and the connecting metal fitting 5 is By screwing the lower end of the bolt 7 penetrated through the center into the nut 8 held near the upper end of the main column 1, and tightening the external nut 7a screwed onto the upper end of the bolt 7. , the main pillar 1 and the auxiliary pillar 101 are pulled toward the connecting fitting 5.

As shown in FIGS. 2 and 3, the connecting fitting 5 is made of a strip plate and has a U-shaped cross section.
The center portion of the bottom wall is bulged in a V shape, and the lower surface side of the bulged portion 51 is a tapered portion 52. On the other hand, the upper frame material 3 of the auxiliary panel 3, 103
1,131 has a concave groove 3 with a V-shaped cross section.
6,136 are formed, and the concave grooves 36,13
Tapered surfaces 37, 13 that expand the inner surface of 6 upward
7. In the illustrated case, the connecting fitting 5 is connected to the upper end surface 10 of the auxiliary panel 103.
By bridging between 3c, the tapered part 5
2 is engaged with the groove 136. Each bolt 6 for fixing the connecting fitting 5 to each panel 3
is adapted to be screwed into a plate-like nut 138 held inside the upper frame member 131.

Note that 91 is an upper end cover that covers the upper end surface of the panel 103, and 92 is a side end cover that covers the opposite side of the end pillar 1, 101 from the panel. Moreover, 93 is a baseboard that covers the space formed between the lower end of each panel 3 and the floor surface 10. This baseboard 93 is removably attached to the pillar 1 using claws 93a.

If the structure is like this, pillars 1 and 101
Since the pillars 1, 101 and the panels 3, 103 are separate bodies, the pillars 1, 101 and the panels 3, 103 can have symmetrical shapes. Therefore, it is more versatile than conventional panels that are asymmetrical in left and right sides.For example, even if one side of the panel 3,103 is different in color from the other side, one type of panel 3,103 can be used to cover both sides. It becomes possible to freely select and assemble into a desired form.

Also, like this, pillars 1, 101 and panels 3, 1
03 is completely separate, and the engaging claws 4, 104 of each panel 3, 103 that bends downward are connected to the pillars 1, 1.
01, assembly errors due to insufficient engagement depth of the engaging claws 4, 104 accumulate in the same direction as the number of panels increases. This phenomenon does not occur. Moreover, the tension force of the bolt 7 draws the columns 1, 101 toward the connecting fitting 5. As a result, the auxiliary panel 103 whose upper end surface 103c is pressed by the connecting fitting 5 and the main panel 3 whose upper end surface 3c is pressed by this panel 103 are pushed down relative to the main column 1 and the auxiliary column 101. As a result, the engaging claws 4, 104 provided on the panels 3, 103 engage with the deepest positions of the engaging holes 2, 102. That is,
The bent portion of the claw body 42, 142 of the engagement claw 4, 104 is the lower end opening edge 21 of the engagement hole 2, 102,
121 or comes very close to it. Therefore, assembly dimensional errors caused by insufficient depth of engagement of the engagement claws 4, 104 with the engagement holes 2, 102 can be made as small as possible.

Further, with such a structure, adjacent panels 3 and 103 can be firmly connected to each other via pillars 1 and 101. Therefore, the wall itself, which is constructed by connecting the plurality of panels 3, 103, becomes a single piece with high rigidity as a whole. Therefore, level adjustment is performed by bringing only the adjusters 11 of the columns 1 at both ends into contact with the floor surface 10, and then by adjusting the adjusters 11 provided at the lower ends of the intermediate columns 1, the intermediate columns 1 are also adjusted. It is also possible to adopt an assembly mode in which the load is placed on the floor surface 10. Therefore,
Compared to the case where level adjustment is performed by adjusting the adjusters of a plurality of pillars by trial and error, assembly and installation work can be significantly speeded up.

Furthermore, when it becomes necessary to reduce the height of the entire wall, first remove the bolts 6 from the plate-like nuts 138, remove the bolts 7 from the nuts 8, and remove the connecting fittings 5 from above the auxiliary panel 103. Thereafter, the auxiliary column 101 and the auxiliary panel 103 are removed from the main column 1 and the main panel 3, and the connecting fitting 5 is bridged between the upper end surfaces 3c of the main panel 3. At this time, the tapered portion 52 of the connecting fitting 5 is engaged with the tapered surface 37 of the groove 36 provided on the upper end surface 3c. Then, a bolt (not shown) shorter than the bolt 7 is passed through the center of the connecting fitting 5, and the bolt is screwed into the nut 8 provided near the upper end of the main column 1 and tightened. . Thereafter, by mounting the upper end cover 91 on the main panel 3, a short partition wall can be obtained. On the other hand, if it is necessary to increase the height of the entire wall, an auxiliary column (not shown) is further installed on top of the auxiliary column 101, and
An auxiliary panel (not shown) is further provided on the auxiliary panel 103, a connecting fitting 5 is bridged between the upper end surfaces of the uppermost auxiliary panel, and a bolt (not shown) is passed through the center of the connecting fitting 5. This requirement can also be met by tightening the nut 8 provided on the main pillar 1. Therefore, if it is like this, as long as the main panel 3 and the auxiliary panel 103 are standardized and a small number of types are prepared,
By appropriately combining them, partition walls of various heights can be constructed. and,
If it becomes necessary to change the height during use, this can be easily done by attaching and detaching the auxiliary panel 103, and there is no need to replace the entire partition wall with a new one.

Note that the present invention also includes an embodiment in which the connecting fitting is a simple plate-like member and no groove is formed in the upper end surface of the panel.

[Effects of the invention] Since the present invention has the above-described configuration, the following effects can be obtained.

As the main and auxiliary columns are still pulled up using bolts passed through the center of the connecting fittings, errors in engagement between the engagement claws and the engagement holes accumulate, causing distortion in the overall shape. It is possible to effectively eliminate the inconvenience and improve assembly accuracy, and it is also possible to improve the overall rigidity and facilitate level adjustment.

Moreover, the height of the entire wall can be selected and changed as appropriate by attaching and removing auxiliary columns and panels, making it possible to reduce the number of types of columns and panels, simplifying production, and making it easier to purchase. A superior practical effect can be obtained by being able to easily and economically deal with subsequent changes in specifications.

Further, since it is possible to make the pillars and panels bilaterally symmetrical, the degree of freedom in use can be increased. Furthermore, since the main panel and the auxiliary panel are separate, it is possible to create a variety of forms that were not previously available by making the two panels different colors or preparing a auxiliary panel with a window. Another advantage is that it can be developed into something with functions.
