Description

  The present invention relates to a support leg for a double floor panel, which is called a laying type. More specifically, the present invention relates to a support leg for a floor panel in which cushioning protrusions are provided on the upper surface of four support legs that support four corners of the floor panel so that no rattling noise is generated between the floor panel and the support leg. .

  With the recent progress of office automation in offices, etc., double floor panels that enable free underfloor wiring have been proposed as floor panels with a wide variety of structures and configurations, and are also being used in various fields. However, recently, a double floor called a so-called laying type construction that does not adjust the height of the panel support legs against some unevenness and unevenness on the floor of the building has been disclosed in Patent Documents 1 to 3. As it is, it has come to be used a lot.

  In this laying type double floor, it forms a single block that supports the collective corners of four floor panels (hereinafter also simply referred to as “panels”) with the corners gathered in one place. Some have been devised to use support legs and reduce the number of support legs to be used.

  However, support legs for floor-laying floor panels that do not have a height adjustment function can cause the following problems due to unevenness or unevenness of the floor slab to be installed, or warping of the panel itself. There are the following problems.

  That is, in the type in which the corners of a panel in which four corners are gathered at one place are supported by one support leg, each panel is provided in a support groove (or gap) formed in a planar cross shape on the support leg. A side wall-like side wall having a substantially bowl-like shape when viewed from the plane is supported by sandwiching the side wall in the support groove portion. In this support mode, the upper surface of the support leg and the panel corner portion corresponding to the upper surface are supported. If there is a small gap between the lower surface of the floor due to unevenness of the floor slab, unevenness, or warping of the panel itself, the minute gap between the upper surface of the leg and the lower surface of the panel will be rattled every time the user walks. In addition, there was a problem that a rattling sound was generated.

Conventionally, as a countermeasure against this rattling, a technique has been proposed in which another member such as a sheet is sandwiched or a different member is pasted in order to fill the gap. However, a countermeasure using such a separate member requires a lot of work. For this reason, the construction cost of the floor panel was increased.

  Therefore, an object of the present invention is to provide a support leg for a double floor panel that is particularly useful when applied to a panel for a double floor panel.

  The structure of the support leg of the present invention made for the purpose of solving the above-mentioned problems is a floor panel which is arranged on the lower surface side of the four corners of the floor panel and is supported by bringing the upper surface into contact with the lower surface of the corner of the panel. The support leg is characterized in that a convex portion having elasticity that abuts against the panel is provided on the upper surface of the support leg.

  The support leg of the present invention can be formed of a single material of a synthetic resin material or a metal material, or a structure using both of them, and the elastic convex portion provided on the upper surface of the support leg is integrated with the support leg. Alternatively, it can be formed separately. However, it is advantageous from the standpoint of manufacturing and durability of the support leg because the support leg and the cushioning convex part provided on the upper surface thereof are integrally molded, since the process of attaching the convex part and the mounting structure are not required. It is.

  In the support leg of the present invention, at least one or two or more cushioning convex portions provided on the upper surface may be provided. In addition, some support legs are formed in a hollow block shape, but some are solid block shapes. The hollow block-shaped support legs are provided with reinforcing ribs so as to withstand a longitudinal load. In addition, although this invention support leg can be formed also in a solid block shape, what was formed in the hollow block shape for reducing a weight is preferable.

  In the present invention, on the outer side in the left-right direction of the support leg, a support leg that supports the corner of the floor panel laid adjacent to the left and right of the panel supported by the support leg, between the support leg, It can be set as the structure formed in the state connected integrally through the support groove part for inserting and supporting the standing-wall-like side edge of two panels.

  In the present invention, in a support leg in which two support legs are integrally connected via a support groove part in between, the width of the support groove part is adjacent to a corner side edge of one floor panel. It is formed so that it can be inserted into the corner side edge of another floor panel that is laid down, and the bottom surface of the corner of the floor panel is formed so that it can abut on the cushioning protrusion provided on the top surface of each support leg. . As a result, each panel in which the side edge is inserted into the groove portion has its lower corner face always in contact with the buffering convex portion, so that no rattling noise is generated by the cushioning action of the convex portion. Further, even if a minute gap is generated between the lower surface of the panel and the upper surface of the support leg due to unevenness or the like, generation of rattling noise can be prevented by the cushioning action of the buffering convex portion.

  In the above-mentioned support leg in which two support legs are arranged side by side, the first panel side edge inserted therein is held in the groove portion and is deformed when the second panel side edge is inserted. Or what provided the structure provided with the holding | maintenance tongue piece which is cut off and the holding | maintenance force of the 1st panel side edge is cancelled | released is preferable. Further, in the present invention, there is a configuration in which a connecting portion for connecting another supporting leg in the front-rear direction is provided on the outer side surface of the supporting leg in the front-rear direction by a male or male fitting or engaging relationship. Furthermore, the support legs arranged at the four corners of the lower surface of the floor panel can be configured to be connected and integrated through a combined body having an X shape in a plan view.

  According to each of the above configurations, the support legs of the present invention can be laid together with the panels in the state of being set at the four corners of the floor panel. Therefore, labor and labor for arranging the support legs and the panels can be saved and arranged. If the support legs are laid while being connected in the front-rear direction, the arranged support legs are connected to each other, so that the support legs are less likely to be displaced, and the placement accuracy of the support legs is improved while saving labor. High floor panel construction can be realized.

  In the present invention, since the support leg that supports the floor panel from below at the four corner bottom surfaces is provided with a convex portion having elasticity that cushions against the panel on the top surface of the support leg, the floor to be installed It is possible to effectively prevent a rattling sound caused by unevenness of the slab, unevenness, or warping of the panel itself.

Next, embodiments of the present invention will be described with reference to the drawings.

It is a top view of the principal part of the example laid and installed.

  1 and 2, reference numeral 1 denotes four support legs of the present invention which are arranged at four corners on the lower surface side of one floor panel P (see also FIG. 9) and support the panel P from the lower surface at the four corners. It is an example. The support leg 1 of the present invention described in this example has two hollow block-shaped support legs 11 and 12 made of a synthetic resin having a substantially rectangular shape when viewed from the plane, and is opposed to the two legs 11 and 12 arranged side by side. It is integrally formed by a bottom 13 through a gap g formed as a support groove on the surface. The bottom portion 13 may be formed with a cutting recess line 13a or the like so that the legs 11 and 12 can be separated. The integrally formed support legs 11 and 12 are preferably made of a synthetic resin material from the viewpoint of productivity and handleability, but may be formed of a metal material or a combination of a synthetic resin material and a metal material. .

  1 and 2, reference numerals 11a and 12a are reinforcing ribs arranged in a plane X inside the legs 11, 12, and 11b and 12b are cylinders arranged at the centers of the ribs 11a and 12a. Reinforcing tube portions 14 and 15, which are reinforcing ribs having a shape, are central portions of the upper surfaces 11c and 12c of the support legs 11 and 12, and are circularly formed around the concentric inner sides of the tube portions 11b and 12b. This is a planar circular cushioning convex portion that is formed so as to form a shallow dome shape by providing the grooves 14a, 15a.

  The bumps 14 and 15 for cushioning have a minute gap between the upper surfaces of the support legs 11 and 12 and the lower surface of the panel P caused by unevenness of the floor surface on which the support legs 1 are installed or warpage of the floor panel P. This is provided to mitigate the rattling noise caused by the sound and the impact applied to the panel P that causes the sound.

1 and 2, the circular cushioning convex portions 14 and 15 have grooves 14a and 15a surrounding the outer periphery of the convex portion, so that the buffering action is secured. It is concentrically formed with a small outer shape. Thereby, the cushioning properties of the convex portions 14 and 15 are secured.
Therefore, if the flat cross-sectional shape of the reinforcing cylinder portions 11b and 12b is a polygonal shape such as a triangle or a quadrangle other than the above-mentioned circle, the planar shape of the buffer convex portions 14 and 15 and the surrounding grooves 14a and 15a Is a similar shape with a size that fits in the flat cross section of the reinforcing cylinder portions 11b, 12b, or a shape that fits in the flat cross section of the cylindrical portions 11b, 12b, such as a circular shape inscribed in the flat cross section of the reinforcing cylinder portions 11b, 12b. By doing so, the cushioning properties of the convex portions 14 and 15 are not impaired by the ribs such as the reinforcing cylinder portions 11b and 12b.

The two support legs 11 and 12 are arranged side by side through the bottom part 13, and a gap g is formed between the opposing surfaces of the both legs 11 and 12 as a groove part for supporting the side edge of the panel P.
In the support leg 1 of the present invention, in addition to the above configuration, as shown in FIGS. 1 and 2, no wall is provided on the lower side of the facing surface where the gap g is formed, and the left support leg in FIG. A sandwiching pocket 16 having a substantially U-shaped cross section is formed in the upper portion of the body 11 so as to tightly fit the standing wall-like side edges of the corners of one floor panel P so as to sandwich the side edges. As shown in FIG. 2, the wall that forms the outside of the U-shaped sandwiching pocket 16 has a thin, generally inverted L shape, and the side edge of the second panel P is inserted into the gap g. It is formed on the holding tongue 17 to be deformed or cut. Here, the upper end portion of the holding tongue piece 17 is formed between the upper portion of the support leg 12 to which it is connected and formed in a thin step portion 17a so that the tongue piece 17 can be easily cut or deformed. Yes.

  In the example of FIGS. 1 and 2 described above, the cushioning projections 14 and 15 provided on the upper surfaces 11c and 12c of the support legs 11 and 12 are substantially at the center of the legs 11 and 12 and In this example, one protrusion is provided inside the cross-sectional inner diameter of the portions 11b and 12b. However, in the present invention, the two protrusions 14 and 15 may be provided as illustrated in FIGS. The two convex portions 14 and 15 shown in FIGS. 3 and 4 are also provided so as to avoid the reinforcing ribs 11a and 12a (with the ribs 11a and 12a interposed therebetween in FIGS. 3 and 4). Although not shown, it is optional to provide three or more convex portions 14 and 15, but in any case, they are arranged on the reinforcing ribs 11 a and 12 a so as not to impair their cushioning properties. Further, the convex portions 14 and 15 provided on the upper surfaces 11c and 12c of the support leg 1 are thin around the convex portions 14 and 15 so that they can easily exhibit cushioning or cushioning properties regardless of the number of the installed portions. It is assumed that grooves 14a and 15a are provided (compared to the thickness of the upper surfaces 11c and 12c).

  In another example of the support leg 1 of the present invention shown in FIGS. 3 and 4, the pocket 16 for sandwiching the first panel side edge is formed by a J-shaped holding tongue piece 17 that is inverted from the upper part of the support leg 12. Is formed. The tongue piece 17 of FIG. 4 is also formed so that the base portion thereof is formed in a thin step portion 17a from the upper surface 12c of the support leg 12 and is easily deformed or cut by insertion of the second panel side edge. . In addition, the reinforcing ribs 11a and 12a have a configuration in which the insides of the support legs 11 and 12 are diagonally crossed when viewed from the plane. In the present invention, the reinforcing ribs 11a and 12a are configured as shown in FIGS. Or it is not restricted to the example of FIG. 3, FIG.

  In the above-described support leg 1 of the present invention, other supports lined up in the front and rear (up and down direction in the figure) on the outer surface orthogonal to the juxtaposed direction (left and right direction in the figure) of the two support legs 11 and 12 arranged in parallel. As a connecting part for connecting the leg bodies 11 and 12 of the legs, a male member 18a that looks convex in the figure and a holding piece that holds the male member 18a by fitting and holding it are inverted in the figure A female member 18b that looks substantially concave is formed.

  The above-described leg 1 of the present invention is an example in which the two support legs 11 and 12 are connected in parallel through the gap g as the support groove portion at the bottom 13. This is also true for one of the support legs 11 or 12. Further, the support legs 1 are not limited to a substantially rectangular shape when the legs 11 and 12 are seen from the plane, but may be a triangle, a quarter circle, or other plane shapes. In short, it is sufficient if the connecting portion (to be described later) with another support leg that supports the floor panel disposed adjacently can be formed on the outer surface.

1 and 2, the state in which the opposite corners of the two panels P are supported from the lower surface by the support legs 11 and 12 is shown in FIGS. It becomes the mode shown.
The side edges of the corners of the two panels P are inserted into the gap g of the support leg 1, but the holding tongue piece 17 is cut at the stepped portion 17a by the insertion of the side edges of the second panel P. And is bent downward by the lower end of the side edge. At this time, the corner lower surfaces facing the upper surfaces 11c and 12c of the support legs 11 and 12 of both panels P are in contact with the buffer convex portions 14 and 15 (see FIG. 7).

When a vertical load (such as a person walking or placing an article) is applied to each panel P supported in the state of FIG. 7, the convex portions 14 and 15 are elasticized by the action of the thin portions of the grooves 14a and 15a. It sinks a little downward. This elastic sinking of the protrusions 14 and 15 prevents the rattling noise that has occurred when there is a minute gap between the lower surface of the panel P and the support legs 11 or 12.
When the longitudinal load applied to the convex portions 14 and 15 disappears, the convex portions 14 and 15 that have been sunk by the elastic action of the thin portions of the grooves 14a and 15a return to their original positions.

  As shown in FIG. 8, the support leg 1 of the present invention of the present invention having two support legs described above, the support legs 11 and 12 positioned on the left and right sides of the panel P, includes a holding tongue. The pieces 17 are disposed symmetrically on the left and right support legs 11 and 12. That is, among the four support legs 1A, 1B, 1C, and 1D of FIG. 8, the support legs 1A and 1C and the support legs 1B and 1D are used by rotating the same thing 360 degrees, but the support legs 1A, 1C The arrangement of the holding tongue pieces 17 of 1B and 1D is symmetrical.

  In the present invention, four sets of support legs 11 and 12 (support legs 1A to 1D in FIG. 8) connected at the bottom 13 forming the support leg 1 are used as an example of a plane X-shaped band-like combined body 19. And can be used in this form. The connection body (see FIG. 8) of the four support legs 1A to 1D integrated by the combined body 3 is hereinafter referred to as a support leg unit. The combined body 19 may be a rod-like body including a pipe in addition to a band, or a flat body in which a middle portion of each side except for the four corners is recessed.

  In the present invention, the holding tongue piece 17 provided in each gap g in each support leg 1 of the support leg unit sandwiches the side edge of the panel P when the first panel P is inserted into the gap g. When the side edge of the eye panel is inserted into the gap g, the tongue piece 17 is deformed or cut into a side edge at the stepped portion 17a (see FIG. 6).

  Therefore, the support leg 1 of the present invention is sandwiched between the standing pocket-like side edges of the four corners of one panel P in the sandwiching pocket 16 of each gap g in the four support legs 11 and 12 located inside in FIG. The floor panel P, which is set on the floor panel P and holds four support legs (1A to 1D in FIG. 8) at the four corners of the lower surface, is skipped, that is, in a checkered pattern (or a staggered pattern) Shape). If it does so, the part with the panel P and the part without the panel P will be arrange | positioned on a floor surface so that checkered pattern shape or a staggered pattern may be made | formed.

  At this time, each support leg 1 is provided with the above-described configuration of the connecting portion (male and female members 18a, 18b), so that each support leg 1 in which the panels P arranged in a checkered pattern or a staggered pattern are set. The male members 18a and the female members 18b of the supporting legs 11 and 12 in one supporting leg 1 are connected to the female members 18b and the male members 18a of the supporting legs 11 and 12 in the other supporting leg 1 facing each other. The support legs 1 are connected (or connected) by engaging (or fitting) with each other from above. Accordingly, the support leg 1 of the present invention in which the panel P is set can realize a jumping arrangement in units of the panel P, that is, a connected checkered pattern or houndstooth arrangement. It is possible to lay the floor panel P on the floor surface by placing the panel P in the space where the panel P is not lined up and the support legs 11 and 12 are exposed. (See FIG. 9).

  Here, since the support legs 11 and 12 are all connected at the connecting portions (18a and 18b) in the arrangement of the above aspect, the arrangement accuracy can be easily increased and an arrangement deviation occurs. Nor. In the present invention, the male and female members 18a and 18b can be replaced with an inverted L-shaped locking portion that is vertically symmetrical with the L-shaped section, a male and female member with a flat fastener, or the like.

  An example of the laying mode is that the support legs 1 of the present invention are arranged in a checkered pattern or a staggered pattern with the floor panel P set, and support legs at four corners of the empty space. In this example, the floor panel P is placed on 11 or 12 to construct a double floor panel.

  In the laying of the double floor panel in the present invention, the facing connecting portions (male and female members 18a, 18b) on the support leg 1 on which the panel P is not set are connected to each other, and then correspond to the four corners of each panel P. It is also possible to adopt a construction method in which the floor panel P is placed on the respective support legs 11 and 12. In this case, if the support legs 1 are integrated with the combined body 19 such as an X shape, the workability is improved and the positional accuracy at the time of arrangement can be secured to prevent positional deviation.

  In the present invention, since the support leg that supports the floor panel from below at the four corner bottom surfaces is provided with a convex portion having elasticity that cushions against the panel on the top surface of the support leg, the floor to be installed It is possible to effectively prevent a rattling sound that has been generated due to unevenness of the slab, unevenness, or warping of the panel itself.
