In this conventional panel receiving component, a panel receiving body serving as a panel support member and a cover member serving as a panel lock receiving member are connected to each other using a locking hole and a connecting hook provided in each as a connecting means. . And the mounting surface area | region where the corner | angular part of a floor panel is mounted has spread on the radial direction outer side of the connection location in which this connection means was provided.
[0004]
[Problems to be solved by the invention]
The panel receiving part is preferably compact on the assumption that it has a sufficient panel support function. The compactness is not only advantageous in terms of inventory and transportation of parts, but is also important from the viewpoint of ensuring a wide space under the floor panel in which electrical wiring and the like are accommodated. On the other hand, in order to perform a sufficient panel support function, it is necessary to secure a sufficiently large mounting surface area, and the panel support member must be capable of withstanding the required bending load. Don't be.
[0005]
Accordingly, the problem to be solved by the present invention is to make the entire panel receiving component compact while ensuring a sufficiently wide mounting surface area and load bearing performance.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a view showing a state in which a floor panel 3 is supported by a floor panel support device composed of a combination of a panel receiving component 1 and a column 2 according to an embodiment of the present invention. (A) is a plan view and (b) is a longitudinal sectional view. In the plan view (a), the area occupied by the panel lock receiving member 4 of the panel receiving component 1 on the panel support member 5 will be described in an easy-to-understand manner. Therefore, the panel lock receiving member 4 shows only the outer contour.
[0011]
The support column 2 on which the panel receiving component 1 is mounted has a support plate 7 that abuts against a base surface 6 such as a concrete slab and spreads in the lateral direction, and a lower end portion is assembled to the center hole of the support plate 7 so It consists of an upright bolt 8 that extends.
[0012]
The panel support member 5 of the panel receiving component 1 is screwed onto the bolt 8 of the support column 2 at an adjustable height position and fixed with a nut 9. A panel lock receiving member 4 is connected on the panel support member 5 in a manner as will be described later. Four connecting points spaced apart from one another along the circumferential direction are denoted by reference numeral 10.
[0013]
Of the peripheral edge of the panel support member 5, the surface of the portion not covered by the panel lock receiving member 4 is provided as a placement surface region 11 for placing the corner of the floor panel 3 (in practice, As will be described later, a cushioning sheet is placed on the upper surface of the panel support member 5. However, it can be said that the placement surface region 11 is provided by the peripheral edge of the panel support member 5 in terms of the essence of the panel support. In the illustrated embodiment, it can be recognized that four placement surface regions 11 are provided between the four connecting portions 10 to support the corners of the four floor panels 3.
[0014]
The floor panel 3 having the corners placed on the placement surface area 11 is supported at an adjustable height position spaced upward from the base surface 6. In order to sandwich and fix each corner of the floor panel 3, the panel lock 12 is locked to the panel lock receiving member 4.
[0015]
Each member will be described. First, the panel support member 5 is shown in FIG. The panel support member 5 includes a base portion 14 in which a screw hole 13 for screwing with the bolt 8 of the support column 2 is formed, and a cup-shaped peripheral wall 15 extending from the base portion 14 so as to expand radially outward. And a mounting wall 16 that spreads outward in the horizontal direction from the upper end of the peripheral wall 15 to form the peripheral edge of the panel receiving component and defines the mounting surface region 11 described above. The placement wall 16 is formed with an opening 17 as a locking means. Recesses 29 are formed at the four corners of the mounting wall 16. In the recess 29, a protrusion formed on the lower surface of the corner of the floor panel 3 is fitted, whereby the placement panel is positioned.
[0016]
FIG. 3 shows a panel lock receiving member 4 connected to the panel support member 5. The panel lock receiving member 4 has an annular upper wall 19 that defines a central opening 18, and four locking claws 20 that extend from the upper wall 19 so as to spread radially outward. ing. The panel lock receiving member 4 can be manufactured by press molding using a surface-treated steel plate. The locking claw 20 is formed at an angular position that aligns with the opening 17 of the panel support member 5, and functions as locking means that interlocks with the opening 17. Specifically, the hook 21 formed by cutting and raising at the distal end portion of the locking claw 20 is engaged with the lower surface of the radially inner edge of the opening 17 to perform locking.
[0017]
The manner in which such locking is performed is shown in FIG. The panel lock receiving member 4 shown in the upper part of FIG. 4 is replaced with the panel support member 5 (mounting part) shown in the middle part under such a relative positional relationship that the locking claw 20 and the opening 17 are in an angular position where they align with each other. When the cushioning sheet 22 made of a soft resin is placed on the mounting wall 16), the hook 21 of the locking claw 20 is moved in the radial inner edge of the opening 17. It hits. When the relative movement is further advanced, the locking claw 20 is elastically deformed radially outward by the cam action of the hook 21 inclined radially inward. When the relative movement is further advanced and the hook 21 completely passes through the opening 17, the locking claw 20 is elastically restored inward in the radial direction, and as shown in the lower stage of FIG. Engage with the lower surface of the edge of the. Such a resilient engagement between the locking claw 20 and the opening 17 not only facilitates the assembly of the panel receiving part 1 in the factory, but also due to its quickness and simplicity, the panel receiving part 1 can be assembled in the field. Allows assembly.
[0018]
The locking between the locking claw 20 and the opening 17 does not necessarily eliminate play between the two. Therefore, when walking on the floor panel 3, rattling occurs between the panel lock receiving member 4 and the panel support member 5, which may generate an annoying sound. The elastic legs 23 formed on the panel lock receiving member 4 solve this problem.
[0019]
As shown in FIG. 3, the elastic leg 23 extends at the angular position between the locking claws 20 so as to spread radially outward from the upper wall 19 in the same manner as the locking claws 20. Yes. However, the length is shorter than the locking claw 20. As shown in FIG. 4, when the panel lock receiving member 4 is assembled to the panel support member 5, the lower end 24 of the elastic leg portion 23 bent outward in the radial direction is placed on the panel support member 5 via the buffer sheet 22. It contacts the upper surface of the wall 16. Until the hook 21 of the locking claw 20 completely passes through the opening 17, the lower end 24 of the elastic leg 23 continues to be pressed against the upper surface of the mounting wall 16 and elastically deforms. When the hook 21 of the locking claw 20 passes through the opening 17 and engages with the lower surface of the radially inner edge of the opening 17, the elastic restoring force of the elastic leg 23 is applied to the panel lock receiving member 4 and the panel support member. 5 are urged away from each other in the vertical direction. As a result, the locking between the hook 21 and the opening 17 becomes tight, and there is no backlash. FIG. 5 shows a side view corresponding to the sectional view of the lower part of FIG.
[0020]
The lower surface of the corner portion of the floor panel 3 supported by the panel receiving component is shaped so as not to interfere with the locking claw 20 and the elastic leg portion 23. Further, the outer slope of the elastic leg 23 functions as a guide when the panel is placed.
[0021]
The panel lock 12 is shown in FIG. As can be easily understood by referring to FIGS. 6, 3, and 1 together, the corners of the floor panel 3 are placed on the placement surface region 11 of the placement wall 16 of the panel support member 5, and then the panel lock 12. The four projections 25 formed in the lower part of the panel lock 12 are aligned with the four recesses 26 formed in the upper wall 19 of the panel lock receiving member 4, and the lower part of the panel lock 12 is placed in the central opening of the panel lock receiving member 4. By inserting it into 18 and rotating the panel lock 12 by 45 degrees, the corners of the floor panel 3 are fixed by the clamping action.
[0022]
An inclined piece 27 formed by cutting and raising a part of the upper wall 19 of the panel lock receiving member 4 and a protruding piece 28 formed by bending a part of the upper wall 19 downward are formed in front of and behind the recess 26. Are provided respectively. The inclined piece 27 plays a role of smoothly guiding the insertion from the lower part of the panel lock 12 to the rotation, and the projecting piece 28 plays a role of preventing excessive rotation of the panel lock 12.
[0023]
As can be understood with reference to FIG. 1 again, the placement surface area 11 for placing the corners of the floor panel 3 is located between the connecting portions 10 between the locking claws 20 and the openings 17. It spreads inward rather than the radial direction position of the connection location 10. Therefore, even if the outer dimension of the mounting wall 16 of the panel support member 5 is not increased so much, the mounting surface area 11 having a sufficiently large width is secured. Accordingly, the panel support member 5 and thus the panel receiving component 1 as a whole can be made compact. In the panel receiving component of the prior art described above, considering that the placement surface area is positioned completely outside the connecting portion in the radial direction, the effect of compactness is that the placement surface region 11 is connected to the connecting portion 10. It is sufficiently exerted by spreading inward to at least the radial position of the connecting portion 10 between the two. Such embodiments are also within the scope of the present invention.
[0024]
In order to place the floor panel 3 as shown in FIG. 1B, first, the installation position of the column 2 is determined on the base surface 6 to support the column 2 with the panel receiving component 1 assembled thereto. The lower surface of the plate 7 is bonded to the base surface 6. The height of the panel receiving component 1 is adjusted on the bolt 8, and the corner of the floor panel 3 is placed on the placement surface region 11. The panel receiving component 1 is fixed by screwing the nut 9 onto the bolt 8 from above and tightening. Thereafter, the corners of the floor panel 3 are fixed with the panel lock 12.
[0025]
【The invention's effect】
According to the panel receiving component of the present invention, the mounting surface area for mounting the corner of the floor panel has at least a radius of the connecting portion between the plurality of connecting portions of the panel support member and the panel lock receiving member. Since it spreads inward to the directional position, the entire panel receiving component can be made compact while ensuring a sufficiently large placement surface area. Moreover, since the length of the moment arm on which the bending load applied to the panel support member from the panel end portion is reduced, the load bearing performance is also improved.
[0026]
If the connection between the panel support member and the panel lock receiving member is performed by the locking between the both locking means, the operation becomes much easier than the connection by welding or screwing. Therefore, on-site assembly becomes possible, and parts can be stocked and transported. Needless to say, the effects of downsizing described above are also advantageous with regard to inventory and transportation.
[0027]
Further, if one of the locking means is a locking claw and the other locking means is an opening that is elastically engaged with the locking claw, an extremely easy and quick connection can be achieved.
[0028]
If the panel lock receiving member is provided with an elastic leg portion extending downward, and the lower end of the elastic leg portion is elastically deformed by being pressed by the panel support member during assembly of the panel receiving component, the panel lock Play (backlash) between the receiving member and the panel support member is eliminated, and generation of an annoying sound when walking on the panel can be prevented.
