Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a ceiling board Cζ, and more particularly to a ceiling board used for tables, desks, etc.

[Conventional technology]

Tables and the like are usually manufactured by connecting legs to a top deck via a frame. And this sky deck is the first
As shown in Fig. It consists of a water core material 6, a back material 7, and a border material 8, which is an outer frame of Cζ, for fixing with screws, etc.The method for attaching the legs 4t to this roof deck is to use a frame 5, Connect the wooden core material 6 with screws, bolts,
A common method is to screw them together using a nut 9 or the like. For convenience of explanation, each component of these conventional tables and desks is shown in disassembled form as shown in FIG.

However, the sky deck used in conventional tables and desks Cζ has the following drawbacks. That is, (a) since the roof deck is screwed to the frame, it is necessary to use a core material made of wood or a material that has enough holding power to be screwed for the screwed part due to its holding power. There is. Since a wooden core material is usually used as the core material of this screwed part, warping is likely to occur due to the influence of humidity, temperature, etc. In addition, because different materials such as paper and wood are bonded to the surface material, the so-called "wavy" phenomenon is likely to occur, where the ridges of the core material appear floating, especially when the surface material is dark in color. There is a major drawback.

(b) Since the roof deck itself is mostly made of wood and paper, there are problems with water resistance, humidity resistance, heat resistance, etc., and in particular, its stability is incomplete.

(c) JLF manufacturing roof decks, surface materials, reinforcing materials,
Since it is manufactured from a large number of parts such as a core material such as a paper core, a backing material, etc., a lot of time and effort is required for adhering and assembling these parts.

In particular, when manufacturing tables and desks using this roof deck, it is also necessary to use frames, screw fastening parts such as bolts and nuts, etc.
It is necessary to assemble the legs, etc., which increases the effort and time.

) When using the special Cζ sky deck for assembling a table or desk,
Since the frame is installed under the roof deck, its aesthetic appearance is impaired.

[Purpose and outline of the invention]

The present inventor paid attention to the above-mentioned drawbacks of the top deck used for conventional tables and desks, and developed a top deck that does not have these drawbacks. We have continued to conduct intensive research to ensure that no table or desk is provided. In this research, we developed a core material made of synthetic resin, preferably foamed synthetic resin, in which a core material for screwing and a core material for screwing are integrated, instead of the conventional core material and core material for screwing. The inventors have discovered that the intended purpose can be achieved by using the core material and by embedding the frame integrally in this core material, and have completed the present invention in a string. That is, the present invention relates to a roof deck characterized by using a synthetic resin core material in which legs or a frame for connecting to the legs are integrally embedded.

[Structure of the invention]

The present invention will be explained below using the drawings. FIG. 8 is a drawing showing an example of a table using the top deck of the present invention.
0 is the sky deck, 11 is the frame embedded in the sky deck, 12
is the leg.

In this FIG. 8(a), the frame 11 and the leg portion 12 are
are expressed integrally, but in the present invention, the fourth
Separate the leg portion 12 and frame 11 as shown in the figure,
Only the frame 11 is buried in the sky deck 10, and this is the flea.
It is also possible to connect the leg portion 12t with a bolt, nut, screw 18, or the like.

Further, as shown in FIG. 8(b) Cζ, the leg portion 12t of Cζ may be embedded as it is without using a frame.

In the structure shown in FIG. 8, the legs 12 and the frame 11
However, in the structure shown in Fig. 4, the legs 12 and the frame 11 are separated, so the legs Only part 12 can be connected after the top deck 101ζ,
This is preferable because the inconvenience shown in FIG. 8 is eliminated.

In the sky deck 10f of the present invention, the shape of the frame can be changed to enable various connection methods depending on the connection method between the frame 11 and the leg portions 12.

For example, as shown in FIG. 5, a frame 14t having a shape as shown at 14 may be used to connect to the ζ leg (not shown) with bolts or nuts, or by welding or the like. In short, a frame with an appropriate shape to which various connection methods can be applied can be used.

Regarding the shape of the frame according to the present invention, not only can the shape be completely changed depending on the connection means with the legs, but also the adhesion between the frame and the synthetic resin, especially the foamed synthetic resin, can be adjusted. Therefore, it is desirable to use the frame by appropriately changing the shape of the frame by Cζ. That is, by changing the shape of the frame, the holding force for the core material of the synthetic resin, especially the foamed synthetic resin, is improved.An example of a preferable frame shape in the present invention is shown in FIG. That's right. To explain in more detail, in the structures shown in FIG. 6 (a) and G/→, the protrusions 15 and 16t are provided in the horizontal direction to increase the contact area between the frame and the synthetic resin, thereby increasing the contact area between the frame and the synthetic resin. It is intended to improve financial performance, and it is also shown in Figure 6 (
In (b), the angle of the frame is changed to disperse the stress applied to frame C. Turtle.

In Fig. 6), the contact surface between the frame and the synthetic resin is particularly large. In any case, it is preferable that the frame structure has as large a contact area with the synthetic resin as possible, and its shape is not particularly limited.

Synthetic resin core material f containing embedded frame of the present invention
, when preparing, it is sufficient to embed the Cζ frame at a predetermined position and mold it integrally with the synthetic resin.

The basic feature of the roof deck of the present invention is that it is formed integrally with a synthetic resin with a frame embedded in a predetermined position, and uses a core material. However, based on this feature, various forms as shown below are included.

First, in the case of a conventional sky deck, which consists of a surface material, reinforcing materials used as necessary, a core core material, a core material for screw fixing, a back surface material, and a border material that is an outer frame, the core core material and the screws are The above-mentioned core material of the present invention is used instead of the fastening core material (Fig. 7). In this case, the border material may be separately joined later [FIG. 7F], or the border material may be formed in advance integrally with the core material of the present invention [FIG. 7(B)]. Also, as shown in FIG. 8, there is a structure fζ, a structure in which only the reinforcing material is completely omitted from FIG. 7, a structure in which the backing material is further omitted from the structure in FIG. A structure in which the frame and back material are shared by changing the structure shown in the figure without using a separate back material, or a structure shown in FIG. 9 as shown in FIG. 11 (in which the surface material is also omitted) A specific example of this structure can be given as a concrete example.

More specifically, by appropriately changing the properties of the synthetic resin used as the core material of the present invention, such as its hardness, flexibility, degree of foaming, etc., or by changing the type of resin as appropriate according to the conditions in which it will be used. By changing the above, it is possible to obtain various forms of the roof board as shown in Figs. A structure as shown in FIG. 9 is preferable, and a structure as shown in FIG. 11 is preferable when a table or desk is covered with something like a cloth.

As mentioned above, the shape of the frame used in the present invention is not limited to the same extent, and the material of the frame must be sufficiently durable when used as a table or desk by integrally connecting the legs. There are no particular restrictions on the material as long as it is made of a material that exhibits strength; typical examples include steel frames, frames made of various metals such as aluminum, frames made of synthetic resin, and wooden frames. etc. can be mentioned.

Further, the synthetic resin is not particularly limited as long as it can be molded integrally with the frame, and various resins such as polyurethane, acrylic resin, and polyester can be used as specific examples. In the present invention, various foamed synthetic resins can be preferably used as the synthetic resin, and specific examples include foamed polyurethane.

In addition, the surface material, reinforcing material, border material, and back material used as necessary in the present invention have conventionally been used for the pilot deck.
All of the things that have been used can be used for beneficial effects.

〔Effect of the invention〕

In the present invention, since the frame is integrally buried and a synthetic resin core material is used instead of the conventional core material or wooden screw core material, The so-called "waving" phenomenon that occurs when using wood does not occur at all. In addition, in conventional sky decks, the core material and the screw-fixing material are made of paper or wood, which has caused problems, but in the present invention, synthetic resin is used, so this problem arises. No difficulties arise at all.

Furthermore, since a synthetic resin core material with a frame embedded therein is used, the number of individual members is reduced, and the time and labor required for assembling and connecting them are significantly reduced.
