Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a frame member constituting a prefabricated structure such as furniture or Efsteria.

[Background technology]

There are many parts for Efsteria on the market, such as fences and garages with one gatepost, but because they require specialized skills and tools to assemble, they often require a contractor.

Furthermore, because the shape of the finished product is limited, it may not match well with the location conditions of the installation site or individual preferences.

[Purpose of the invention]

This invention was made in view of the above circumstances,
The object of the present invention is to provide a prefabricated frame member for Efsteria, etc., which can be easily assembled with simple tools, and which can be applied in a wide range of applications and allows the creativity of individuals to be utilized during assembly.

[Disclosure of the invention]

That is, the prefabricated frame member according to the present invention can be used for furniture,
A frame member constituting a prefabricated structure such as Efsteria, near the end thereof, the part from the center becomes a large diameter part, and the part communicating from this large diameter part to the end face becomes a groove-like small diameter part, and a frame member having a concave portion that opens on the side surface as a whole, and a bulge portion that fits into the large diameter portion at both ends, and a small diameter portion that has a middle portion longer than the small diameter portion and fits into the small diameter portion. It consists of a joint that serves as a shaft, and a set bolt that fixes the joint and the frame material in a state where the joint is fitted into a recess.

This will be explained below based on the embodiments shown in the drawings. Fig. 1 is an external view of a structure constructed using the prefabricated frame member according to the present invention, and Fig. 2 is an enlarged view of the main parts thereof. This is an explanatory diagram showing an example in which the prefabricated frame member 1 is used to assemble a fence. The prefabricated frame member 1 includes a frame material 2 made of resin concrete or cast iron, a joint 3 as a connecting tool, and a set as a fixing tool. Consists of 4 bolts. The frame member 2 is formed by integrally molding vertical members 7.7 with a semicircular cross section on both ends of a horizontal bar 6 with a circular cross section with the plane side facing outward. A recess 9 having a semicircular cross section and consisting of a large diameter part 9a and a small diameter part 9b is provided at both ends of the vertical member 7 on the plane side, with the small diameter part 9b opening at both ends of the vertical member 7. The joint 3 includes a bulge portion 3a that fits well into the large diameter portion 9a at both ends of the small diameter shaft portion 3b that fits into the small diameter portion 9b;
3a are integrally formed, and the shaft portion 3b is formed by connecting two parts of the small diameter part 9b.
It has been formed to double the length. That is, the recess 9 is
It has approximately the same shape as a 1/4 solid shape of the joint 3 obtained by cutting the joint 3, which has bulges 3a, 3a on both sides of the shaft portion 3b, along a plane passing through the central axis and a plane perpendicular to the central axis. .

Further, at the bottom of the large diameter recess 9a of the vertical member 7, there is a through hole 10 through which the set bolt 4 can be inserted toward the outer peripheral surface.
A through hole 11 having the same diameter is provided in the bulging portion 3a of the joint 3 at a position overlapping with the through hole 10. It is preferable that the through hole 10 of the vertical member 7 is formed as a stepped hole having a large diameter on the outside so that the head of a set bolt 4 and a nut 4a, which will be described later, are hidden therein.

To assemble this frame assembly type frame member 1, the recesses 9 and 9 of a pair of vertical members 7. , 11.10 and tighten with nut 4a. The remaining half of the joint 3 protruding upward or downward from the vertical members 7, 7 is also connected to the pair of vertical members 7, 7 in the same manner as above.
Fit into the recess 9°9 and tighten the frame members 2, 2 with the set bolt 4.
join. In this way, a pair of semicircular vertical members 7
．． At 7, a vertical support 13 having a circular cross section is formed. Further, the upper and lower vertical columns 13.13 are also connected to each other by joints 3.

In this way, by developing the horizontal joints and vertical joints of the frame members 2, the frame assembly type frame F can be assembled to any desired length and height.

The frame assembly type frame part jA1 is extremely easy to assemble,
Its bonding strength is high. Note that the frame material 2' used at the end of the frame assembly type frame F may have the vertical member 7 or the horizontal beam 6 protruding in only one direction. Also, as shown in Figure 3,
In the corner frame material 2, the horizontal crosspiece 6 may be formed with an angle θ inclined within the horizontal plane.

The panel 15 to be fitted into the frame assembly type frame has recesses 16 on the upper, lower, left and right end surfaces in which the horizontal bars 6 and the vertical members 7 of the frame material 2 engage.
, 1'7 are provided respectively. It would also be convenient to prepare optional materials with recesses similar to the recesses 9 of the frame material 2, such as a lighting unit 19 housing a lighting device and a special unit 2° equipped with a mailbox or intercom. .

Further, FIGS. 4 to 9 show examples of the garden set including a table, chairs, and lighting lamps. Reference numeral 22 denotes a mating material that matches the vertical members 7 of the frame material 2 to complete the legs. 23 and 24 are optional table tops, 25 is a chair base, and 2'7, 28 and 29 are lighting covers. It is convenient to prepare such various optional materials because the range of applications will be expanded.

It goes without saying that it can be used with the horizontal beams oriented vertically as shown above, or with the sewing members oriented horizontally.

〔Effect of the invention〕

As explained above, the prefabricated frame member according to the present invention can be easily assembled by simple fixing and used as a prefabricated frame for a structure, and can be made by using Mooffsion's accessories. Therefore, it can be applied to a wide variety of fields. Note that when this prefabricated frame member is used for furniture or indoor structures, it can be made suitable for indoor use by using wood, synthetic resin, or the like as the material.
