DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor panel support for supporting a floor panel on a concrete floor or the like.

[0002]

2. Description of the Related Art Conventionally, a tubular member and a panel receiving portion are provided, and the tubular member is inserted into a hole provided in the floor panel so that the floor panel is placed on the panel receiving portion. On the other hand, a floor panel is supported on the base floor surface by screwing a male screw portion of a screw post vertically set on a concrete floor surface or the like to a female screw portion provided on the inner periphery of the tubular material. Floor panel supports are known.

[0003]

In this type of conventional floor panel support, in order to prevent rotation and detachment of the tubular member with respect to the floor panel, the panel receiving portion is bonded to the floor panel with an adhesive. It was necessary to fix the panel receiving portion to the floor panel with screws and the like.

[0004] The present invention has been made in view of such circumstances, and provides a floor panel support in which rotation and detachment from the floor panel are suppressed only by inserting a tubular member into a hole in the floor panel. The purpose is to:

[0005]

According to a first aspect of the present invention, there is provided a floor panel support, comprising: a tubular member inserted into a hole provided in a floor panel; and a screw support provided on an inner periphery of the tubular member. A floor panel support comprising: a female screw portion to which a male screw portion provided on the outer periphery of the female member is screwed; and a panel receiving portion provided on the cylindrical member and on which the floor panel is placed. At the portion of the floor material to be inserted into the hole of the floor panel, the cylindrical member was axially compressed so as to expand outward over the entire circumference to form a bulging portion that was pressed into the hole. Things.

A floor panel support according to a second aspect of the present invention includes a tubular member inserted into a hole provided in the floor panel, an inner peripheral portion of the tubular member, and an outer peripheral portion of the screw post. A female screw portion to which the male screw portion is screwed, and a panel receiving portion provided on the tubular material and having a panel receiving portion on which the floor panel is placed. A portion that is inserted into the hole of the floor panel is provided with a cut-and-raised portion that is cut and raised outward.

[0007]

According to the first aspect of the present invention, when the bulging portion of the panel support is pressed into the hole of the floor panel, the bulge bites into the wall surface of the hole of the floor panel. Rotation and detachment are suppressed.

If a groove is formed in the surface of the bulging portion in the vertical or oblique direction, the wall surface of the hole in the floor panel will bite into the groove, and the rotation of the floor panel support relative to the floor panel will be more effective. Can be prevented.

In the second aspect of the present invention, when the floor panel is made of a relatively hard material, if the amount of protrusion of the cut-and-raised portion to the outside is appropriately set, the tubular member of the panel support can be placed on the floor. When the cut-and-raised portion is inserted into the hole of the panel, the cut-and-raised portion is pushed back inside by the wall surface of the hole of the floor panel, and the cut-and-raised portion cuts into the wall surface, so that the rotation and detachment of the floor panel support with respect to the floor panel are suppressed.

[0010] Conventionally, the panel receiving portion is a separate member from the tubular member. However, in the first and second aspects of the present invention, the panel receiving portion is formed by compressing the tubular member in the axial direction. If the peripheral wall of the cylindrical member is formed by being bent so as to be double folded and spread outwardly in a brim shape, the panel receiving portion can be integrally formed with the cylindrical member. Since it is not necessary to attach the portion to the tubular member, cost can be reduced.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the embodiments shown in the drawings. 1 to 4 show a first embodiment of the present invention. In the present embodiment, the entire panel holder 1 is constituted by a single tubular member 2 made of metal such as steel. A panel receiving portion 3 is provided at a portion near the upper end of the tubular member 2. The panel receiving portion 3 compresses the tubular member 2 in the axial direction in a state where it is restrained so as not to be deformed in the radial direction except for the portion where the panel receiving portion 3 is to be formed.
It is formed by plastically deforming the peripheral wall of the portion where the panel receiving portion 3 is to be formed so as to be double-folded over the entire circumference and spread radially outward in a brim shape.

The panel support 1 includes a panel receiving portion 3.
Above, a bulging portion 4 is provided. The bulging portion 4 compresses the tubular member 2 in the axial direction while constraining the cylindrical member 2 so as not to be deformed in the radial direction except for the portion where the bulging portion 4 is to be formed. Is formed by swelling the peripheral wall of the portion where the is to be formed outwardly over the entire circumference. In terms of the processing surface, the difference between the shapes of the panel receiving portion 3 and the bulging portion 4 is mainly caused by the difference in the timing of ending the compression in the axial direction. In other words, when the tubular material 2 is compressed, it first bulges outward like a bulging portion 4, and when it is further compressed, it is folded twice like a panel receiving portion 3 and overlaps radially. Deforms so as to spread outward in a brim shape.

A portion near the lower end of the panel support 1 is narrowed to a small diameter to form a small diameter portion 5, and a female screw portion 6 is provided on the inner periphery of the small diameter portion 5.

FIG. 4 shows an example of a use state of the panel support 1. A hole 8 is vertically penetrated through a floor panel 7 made of a relatively soft material such as wood or plastic, so that the floor panel 7 is placed on the panel receiving portion 3 and a panel support is provided on the hole 8. The bulging part 4 of the tool 1 is press-fitted. A male screw portion 10 provided on a screw post 9 is screwed into the female screw portion 6 of the panel support 1, and the screw post 9 is set up on a foundation floor surface 11 such as a concrete floor surface in the vertical direction.

In the panel support 1, the bulge 4
Is pressed into the hole 8 of the floor panel 7, the bulging portion 4 bites into the wall surface of the hole 8 of the floor panel 7, so that rotation and detachment of the floor panel support 1 with respect to the floor panel 7 are suppressed.

Conventionally, the panel receiving portion 3 is made of a cylindrical material 2.
However, in the present embodiment, the cylindrical member 2
Is compressed in the axial direction to deform the peripheral wall of the cylindrical member 2 so that the peripheral wall is double-folded and spread outwardly in a brim shape, so that the panel receiving portion 3 is formed. Since the receiving portion 3 can be formed integrally, there is no need to attach a separate panel receiving portion to the tubular member 2 as in the related art.
Cost can be reduced.

FIG. 5 shows a second embodiment of the present invention.
In this embodiment, the panel receiving portion 3 of the panel support 1 is used.
The portions other than the bulging portion 4 have the same diameter, and a female screw portion 6 is provided on the entire inner periphery of these portions. Other configurations are the same as in the first embodiment. In this embodiment, the same effects as those of the first embodiment shown in FIGS. 1 to 4 can be obtained.

FIG. 6 shows a third embodiment of the present invention.
In the present embodiment, the panel receiving portion 3 is the panel support 1
At the bottom. The other configuration is the same as that of the second embodiment shown in FIG. In this embodiment, the same effects as in the case of the first embodiment can be obtained.

FIG. 7 shows a fourth embodiment of the present invention.
In this embodiment, the panel receiving portion 3 is a separate member from the tubular member 2 and has a disc shape with a central portion depressed and a hole 12 provided in the central portion. A part of the peripheral wall of the tubular member 2 is applied to the tubular member 2 over the entire circumference by a method similar to the method of forming the panel receiving portion 3 in each of the above embodiments.
A plastically deformed portion 13 is provided which is plastically deformed so as to be heavily folded and spread radially outward in a brim shape. The cylindrical member 2 is inserted into the hole 12 of the panel receiving portion 3 and the plastic deformation portion 13 is brought into contact with the panel receiving portion 3. Similarly to the deformed portion 13, the plastically deformed portion 14 is formed by being double-folded over the entire circumference and plastically deformed so as to spread radially outward in a brim-like shape, thereby forming the plastically deformed portion 14 and the plastically deformed portion 1.
3 crimps the panel receiving portion 3 by sandwiching the panel receiving portion 3. Thereby, the tubular member 2 is fixed to the panel receiving portion 3 (the plastic deformation portions 13 and 14).
May be reversed, or the cylindrical member 2 is inserted into the hole without any plastic deformation portion, and two plastic deformation portions corresponding to the plastic deformation portions 13 and 14 are simultaneously formed. By doing so, the panel receiving portion 3 may be swaged with the tubular member 2). Other configurations are the same as those of the first embodiment shown in FIGS.

Also in this embodiment, the swelling portion 4
Is provided, the same effect as in the first embodiment can be obtained except that the panel receiving portion 3 cannot be formed integrally with the tubular member 2.

FIGS. 8 to 10 show a fifth embodiment of the present invention. In this embodiment, the groove 16 is formed on the surface of the bulging portion 4.
Are provided in the vertical direction. Other configurations are shown in FIGS.
Is the same as in the first embodiment. In the present embodiment, when the bulging portion 4 is pressed into the hole 8 of the floor panel 7, the wall surface of the hole 8 bites into the groove 16, so that the effect of preventing the floor panel support 1 from rotating with respect to the floor panel 7 can be improved. it can. In addition,
The groove 16 may be provided in an oblique direction.

FIGS. 11 to 15 show a sixth embodiment of the present invention. This embodiment is suitable when the floor panel 7 is made of a relatively hard material such as concrete reinforced with an iron plate. FIG. 11 shows a state before the bulging portion 4 is formed at the stage of the manufacturing process of the present embodiment, and the cylindrical member 2 is formed.
An appropriate number of cut-and-raised portions 15 is formed in a portion where the bulging portion 4 is to be formed. This cut-and-raised portion 15 is cut and raised so that only its upper end is left uncut, and the lower end side protrudes outward largely. Other configurations are the same as those of the first embodiment shown in FIGS.

FIGS. 12 to 15 show the completed state of the present embodiment, in which the bulging portion 4 is formed after the cut-and-raised portion 15 is formed. FIG. 15 shows an example of a use state of the panel support 1. In this embodiment, if the amount of protrusion of the cut-and-raised portion 15 to the outside is set appropriately, when the bulging portion 4 is inserted into the hole 8 of the floor panel 7, the cut-and-raised portion 15
The wall is pushed inward by the wall and the cut-and-raised portion 15 cuts into the wall, so that the rotation and detachment of the floor panel support 1 with respect to the floor panel 7 are suppressed.

The bulging portion 4 is not necessarily provided, but if the bulging portion 4 is provided with the cut-and-raised portion 15 as in this embodiment, the cylindrical member 2 is tapered and the hole 8 of the floor panel 7 is formed. In addition, the cut-and-raised portion 15 can be more strongly cut into the wall surface of the hole 8 of the floor panel 7 by the elastic effect of the bulging portion 4.
