Abstract

PURPOSE: To variably use a piece of furniture according to the using purpose by providing burr-like projections on wood screw fitting holes to be kept in contact with a top plate, hooks at three-face corners, and leg fitting screws on the back side of a top plate fitting face, and boring wood screw fitting holes on two side plate fitting faces erected by 90 deg. from the top plate fitting face. CONSTITUTION: When three-way fasteners 1 are permanently fastened at four corners of a top plate 2 while gaps A are set between the side plate fastening faces of three- way fasteners 1 and the cut faces of the top plate 2, burr-like projections 3 around the fitting holes of the top plate 2 bite into the top plate 2, and the top plate 2 is fixed. When four side plates 6 cut to 45 deg. at both ends are fastened by wood screws, the side plates 6 are pulled inward, the connection face gaps between the top plate 2 and the side plates 6 become the minimum because there are gaps A between the side plate fastening faces of the three-way fasteners 1 and the side plates 6. When an adhesive is concurrently used, a dedicated tool such as a clamp is required. Legs and a heater are fitted on the back side of the top plate 2 as required to form a desk with the heater. When a curtain is stretched by hooks 4 and a magic tape, it can be used as a kotatsu (foot warmer).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a furniture using a three-way fastener according to claim 1 and using a three-way fastener that changes according to a desk kotatsu and a purpose of use while a floor is freely installed at a place of installation. is there.

[0002]

2. Description of the Related Art Conventionally, there has been a method of mounting a leg mounting metal fitting only on a top plate and a three-way fastening metal fitting, a top plate, a side plate, and a leg, which are mainly mounted from the outside of a corner. Between the floors
The desk and kotatsu are special items.

[0003]

[Problems to be Solved by the Invention]

(A) Assembling furniture required skill and nobody could easily assemble it. It took time to assemble it. (B) Many households have no floor space due to housing conditions. (C) The kotatsu futon is dusty and has a problem in storage. (D) Furniture is exclusive. The present invention has been made to solve the above drawbacks.

[0004]

[Means for solving the problem] Anti-slip protrusion (3)
After fully tightening the three-way clamp (1) with the top plate (2), surround the four side plates (6) with both ends cut at 45 degrees in the cut edge of the top plate (2), and tighten with wood screws. After the final tightening, secure a clearance between the side plate tightening surface of the three-way clamp (1) and the side plate (6), and attach the velcro tape ^{▲ R ▼} (10) on the back side of the side plate (6).
It is a furniture using a three-way fastener, characterized in that a hook (4) can be hooked (9) and a curtain (8) and a heater (11) can be retrofitted.

[0005]

Operation: As shown in FIG. 1, there is a gap A of about 0.7 mm between the side plate tightening surface of the three-way clamp (1) and the cut surface of the top plate (2).
After setting, tighten all four corners of the top plate (2). The burr-shaped protrusions (3) intentionally provided on the circumference of the mounting hole of the top plate (2) by fully tightening are difficult to insert into the top plate (2), and the side plates (6)
When tightening, the three-way clamp (1) is fixed to the top plate (2) without moving. When the four side plates (6), both ends of which are cut at 45 degrees, are tightened with wood screws, the side plates (6) are drawn inward. After the main tightening is completed, the side plate tightening surface of the three-way clamp (1) and the side plate (6) The gap A between the top plate (2) and the four side plates (6) minimizes the gap between the joint surfaces, which is effective for clamping with an adhesive and is a dedicated tool such as a clamp. Becomes unnecessary. Attach the legs (7) as needed, attach the heater (11) to the back side of the top plate (2) to make a desk with a heater, hook (4) and Velcro ^{▲ R ▼} (10) to curtain (8) Used as a kotatsu.

[0006]

EXAMPLES Examples of the present invention will be described below. By setting a gap A between the side plate tightening surface of the three-way fastening member (1) and the side plate (6), the joint surface gap of each wood is minimized. The size of the top plate (2) is four pieces of decorative plywood (45 cm x 90).
cm) or (60 cm x 90 cm) surrounds each side with four side plates (6) cut at 45 degrees so that each cut is invisible.
The top plate (2) and the side plate (6) have no dimensional error and are assembled by the three-way clamp (1).
It maintains the flatness of and becomes sturdy. (A) The one assembled with the top plate (2) and the four side plates (6) is
Use as a free floor between the installation locations. (B) Select the long leg or short leg for the leg (7) and use it as a chair or a writing desk. (C) Attach the heater (11) to make a desk with a heater. (D) Attach the curtain (8) and use it as kotatsu. Hook four hooks (9) attached to the curtain (8) on the hook (4). Velcro ^{▲ R} pasted to the back side of the curtain (8) intermediate part is plate (6) of the latch (9) ^▼
Stop at (10). The curtain (8) fits between the side plate (6) and the leg (7), and since the adhesive surface of the curtain (8) is inside the side plate (6), it will not come off or be disturbed even if the limbs are touched.

[0007]

[Effect of the Invention] A single family such as a student or a newlywed family does not have a space to put many kinds of furniture. It is also disadvantageous financially. There is no waste by selecting the necessary parts. You can not concentrate on learning in the atmosphere of conventional kotatsu, it is not seasonal like kotatsu, you can use it all year round and you do not need to store it
The curtain is dusty like a futon and not bulky when stored. By using the three-way fastener of claim 1 of the present invention,
Assembling does not require skill and can be assembled in a short time. Since the cut surface of the top plate cannot be seen, even if cheap decorative plywood is used, there is a sense of quality. The top plate and side plate are integrated to make it sturdy.
