Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to the improvement of a support device for the upper part of a column used for partitions or display shelves, etc., and it fixes the column to the lower surface of the ceiling or horizontal rail, etc., and also connects wiring cords. The present invention relates to a support device for the upper part of a column that has a function for insertion.

[Conventional technology]

Conventionally, many support devices for the upper part of the pillar have been provided with an adjuster structure in which the distance between the upper end of the pillar and the lower surface of the ceiling or horizontal beam is different, and the support device has a vertical adjustment function to ensure secure fixation. In addition, there is also a device in which a wiring cord that degrades the appearance of the room is inserted into the pillar, and then inserted into the ceiling or horizontal rail from the upper end of the pillar. for example,
As disclosed in Japanese Utility Model Publication No. 56-19616, a device is provided in which a wiring cord is inserted through the inside of a support column, pulled out from the upper end of the support support, and then connected to a connector provided on the lower surface of the ceiling. However, between the top end of the pillar and the ceiling, the wiring cord is largely exposed to the side, and the connector or the hole in the ceiling is exposed, so the problem with appearance has not yet been resolved, and it is difficult to implement in practice. As disclosed in Publication No. 56-1849, a through hole penetrating in the axial direction of a vertically installed screw shaft is provided in the center of the mounting board, and the screw shaft is inserted into the upper end of the support column. A receiving metal fitting screwed onto the shaft is provided, which has a vertical adjustment function by abutting against the upper end of the support, and also allows a wiring cord to be inserted into the through hole of the screw shaft. Although no wiring cord is exposed between the top end and the ceiling, it takes time and effort to drill holes in the axial direction of the screw shaft, which not only hinders cost reduction, but also prevents the wiring cord inserted through the screw shaft from being exposed from the ceiling. If the positioning is not done accurately when drilling the hole for guiding the inside, there is a risk that the distance between the pillars will change, and once the pillar is fixed to the ceiling, the wiring cord cannot be If it becomes necessary to insert the support, the support must be removed, which takes time and effort, and even more labor is required if the support is used to assemble a structure such as a partition. It was hot.

[Problem that the invention attempts to solve]

In view of the above-mentioned situation, the present invention aims to solve the problem by making it possible to fix the upper end of the support to the ceiling or the lower surface of the horizontal beam in a vertically adjustable manner, and to connect the wiring cord inserted into the inside of the support to the ceiling. etc., the wiring cord does not protrude to the side of the support, the insertion hole opened in the ceiling etc. is not exposed to the outside, and the support is fixed to the underside of the top plate etc. It is an object of the present invention to provide a supporting device for the upper part of a support column, which allows the user to easily position and open an insertion hole in a top plate or the like while the support support is fixed.

[Means for solving problems]

In order to solve the above-mentioned problem, the present invention provides a support plate that can be fixed to the lower surface of a ceiling or a horizontal beam, and a screw shaft with an adjustment member screwed thereon installed at a position eccentric to one side from the center of the support plate. The lower end of the screw shaft is inserted into a support hole opened at a position eccentric to one side from the center of the upper end surface of the hollow support, the adjustment member is brought into contact with the upper end surface, and the upper end surface of the support plate and the support support is brought into contact with the upper end surface. A supporting device for the upper part of the pillar is constructed by providing a through hole communicating with the lower surface of the ceiling or the horizontal beam and the inside of the pillar, respectively, at positions eccentric to the other side.

The adjustment member screwed onto the screw shaft is inserted into a support hole opened at an eccentric position in the direction, and the adjustment member screwed onto the screw shaft is brought into contact with the upper end surface, and the support plate is pressed and fixed to the lower surface of the top plate or horizontal crosspiece. Attach the pillar to the other side of the upper end surface of the support plate and the pillar, that is, at a position eccentric to the opposite side from the screw shaft and the mounting hole, so that it communicates with the lower surface of the ceiling or horizontal beam, etc., and inside the pillar, respectively. The wiring cord passed through the pillar is inserted into the through hole provided in the support plate, and the wiring cord is inserted through the support plate at a position corresponding to the through hole in the support plate on the lower surface of the ceiling etc. The lower surface can be viewed directly from below through the through hole of the support plate so that the hole can be easily drilled.

〔Example〕

Next, the present invention will be further explained in detail based on the embodiments shown in the accompanying drawings.

FIG. 1 shows a typical embodiment of the present invention.
indicates a support device, and B indicates a support column. The support device A has a support plate 3 on the upper part that can be fixed in contact with the lower surface 2 of the top plate 1, and a locking member protruding outwardly at the lower edge of a flat cylindrical body 4 in the center of the support plate 3. An annular attachment part 6 forming an edge 5 is provided below, and a second
As shown in the figure, a screw shaft 8 on which an adjustment member 7 such as a nut is screwed is vertically provided at a position of the support plate 3 that is eccentric to one side from the center inside the annular mounting portion 6, and A through hole 9 penetrating upward is formed in the support plate 3 at a position eccentric to the other side from the center inside the mounting portion 6. Incidentally, in order to firmly attach the support plate 3 to the lower surface 2 of the top plate 1, and to firmly fix the screw shaft 8, the support plate 3 has a base plate 10 made of rope embedded therein. The substrate 1 is attached to both ends of the support plate 3.
A mounting hole 11 passing through the bottom surface 2 of the top plate 1 is provided.
The upper end of the screw shaft 8 is directly welded to the substrate 10.

The support column B has a structure in which the upper end of a hollow rod is closed by an upper end surface 13, and the upper end surface 13 has a rod located at a position eccentric to one side from the center according to the position of the eccentric screw shaft 8. A support hole 14 into which the lower end of the screw shaft 8 can be fitted is formed, and a through hole 15 facing the through hole 9 of the support plate 3 is formed at a position eccentric to the other side from the center. There is. Incidentally, the support column B may have various rod structures as long as it is a hollow rod whose upper portion is closed by the upper end surface 13. For example, as shown in FIG. 3, on the upper end of a hollow rod 16 having a structure in which two opposing surfaces are depressed inward in a stepped manner, a lid 17 which is separately formed and approximately matches the cross-sectional shape of the hollow rod 16 is attached. The lid body 17 has protrusions 19, which can be fitted into the recesses 18, formed at the upper end of the hollow rod 16, projecting downward. The same support holes 14 and through holes 15 formed in the upper end surface 13 are provided at the same positions. By constructing the support column B with the hollow rod 16 and the lid 17, the lid 17 can be removed from the hollow rod 16 by loosening the adjustment member 7, and the wiring can be routed into the hollow rod 16. This not only makes it easier to perform the work, but it is also convenient because the support device A can be removed while the support column B remains erected.

In addition, in this embodiment, a bellows 2 is provided between the support plate 3 and the upper end of the support column B for the purpose of improving the appearance.
I am trying to set it to 0. The bellows 20
is formed with a mounting portion 21 that fits externally into the annular mounting portion 6 at the upper end thereof, and a protrusion 22 that can be locked with the locking edge 5 on the inner periphery of the mounting portion 21, Furthermore, a bottom plate 23 is provided at the lower end as shown in FIG.
An engaging hole 24 is formed in the bottom plate 23 by partially overlapping openings having a shape corresponding to the shape of the adjusting member 7 in plan view so that the adjusting member 7 can be externally fitted therein. ing. That is, when a hexagonal nut is used as the adjustment member 7 as in this embodiment, the engagement hole 2
The shape No. 4 has an inner shape equal to the outer shape of two hexagons overlapped.

Thus, in the support device for the upper part of the column of the present invention, the adjustment member 7 is screwed onto the tip of the screw shaft 8 provided below the support plate 3 of the support device A, and the tip of the screw shaft 8 is attached to the top of the column. B is inserted into the support hole 14 opened in the upper end surface 13, and the adjustment member 7 is inserted into the upper end surface 13.
from above, and the support plate 3 is brought into contact with the top plate 1.
At the same time, the adjustment member 7 is rotated and moved downward, thereby pressing the lower surface 2 of the top plate 1 and the upper end surface 13 of the support column B to each other, thereby attaching the support support B. For more secure fixing, screws 12, 12 are inserted into the mounting holes 11, 11 of the support plate 3 and screwed onto the lower surface 2 of the top plate 1. Incidentally, the support plate 3 may be screwed before attaching the support column B. In that case, the support hole 14 in the upper end surface 13 is aligned with the lower end of the screw shaft 8 by tilting the support plate B. After insertion, the adjustment member 7 is rotated and pressed and fixed as described above. Then, the mounting portion 21 at the upper end of the bellows 20 is fitted onto the annular mounting portion 6 of the support plate 3, and
The protrusion 19 is engaged with the engagement edge 5, and one side of the engagement hole 24 formed in the bottom plate 23 at the lower end is fitted onto the adjustment member 7 to cover the screw shaft 8. It is.

In addition, a wiring cord 25 is installed inside the support column B from the top plate 1 or a wiring duct such as a horizontal beam (not shown).
When inserting the insertion hole 26 through the support plate 3, an insertion hole 26 is formed in the lower surface 2 of the top plate 1 corresponding to the through hole 9 of the support plate 3. With the plate 3 in contact with the lower surface 2, insert a scribing needle or punch through the through hole 9 and position it, then remove the support plate 3 and drill a hole, or fix the support plate B and place it in place. When the support column B is used to construct a structure such as a partition, the through hole 9 can be opened by lowering the mounting portion 21 of the bellows 20.
Since the lower surface 2 can be viewed from below through the hole, it is also possible to insert a drill through the through hole 9 and directly drill the hole in that state. Here, the shape of the through hole 9 is changed between the screw shaft 8 and the through hole 9.
If it is made into an ellipse extending in a direction perpendicular to the center line connecting the two, it is practical because the drill can be easily inserted at a slight angle from the side without being obstructed by the screw shaft 8. . In this way, the adjustment member 7 was inserted from the duct above the top plate 1 into the insertion hole 26 and the through hole 9 of the support plate 3, and was engaged inside the bellows 20 and within the engagement hole 24 of the bottom plate 23. It can be inserted into the remaining opening and the through hole 15 in the upper end surface 13 of the column B, and guided into the interior of the column B.

[Effect of idea]

According to the support device for the upper part of the column of the present invention as described above, the screw shaft to which the adjustment member is screwed is lowered at a position eccentric to one side from the center of the support plate that can be fixed to the lower surface of the ceiling or horizontal beam. At the same time, the lower end of the screw shaft is inserted into a support hole opened at a position eccentric to one side from the center of the upper end surface of the hollow support, and the adjustment member is brought into contact with the upper end surface, and the support plate and A through hole is provided at a position eccentric to the other side of the upper end surface of the support column, which communicates with the lower surface of the ceiling or horizontal beam, etc., and inside the support.
The support plate is inserted into a support hole opened in the upper end surface of the hollow support, and the adjustment member screwed onto the screw shaft is brought into contact with the upper end surface, and the support plate is pressed against the lower surface of the top plate or horizontal beam. The support plate can be firmly attached even when the distance between the lower surface and the upper end of the support plate is different, and a screw shaft is provided at a position eccentric to one side from the center of the support plate, and eccentric to the other side. By providing the support plate at a position eccentric to one side from the center of the upper end surface of the support and providing a through hole at a position eccentric to the other side, the top plate Pull out the wiring cord from the wiring duct, etc., through the insertion hole penetrating the bottom surface of the top plate, etc.
The wiring cord can be inserted into the support from the through hole in the support plate through the through hole in the upper end of the support, and the wiring cord can be routed along the spiral shaft between the upper end of the support and the lower surface of the top plate, etc. Not only does it have an excellent appearance, but it is also extremely easy to set the position for drilling the insertion hole because the lower surface can be viewed from below through the hole in the support plate. There is no need to remove the support plate from the bottom surface before doing this, and it can also be done directly by inserting a drill into the through hole from below with the support plate still attached. This is very convenient when assembling structures.
