Description

The present invention relates to furniture with translucent glass tops, and more particularly to leg furniture.

Conventionally, there has been little adhesion between glass that does not change shape due to changes in humidity and wood that changes due to changes in humidity such as wood.
Conventionally, a table in which a metal part is bonded to the lower surface of the translucent glass top and a leg is attached has been seen.
Patent Document 1 discloses a table having a convex or concave supported portion fixed to the lower surface of four corners of a glass top plate.

Japanese Patent No. 4740714

The characteristic of translucent glass is that the other side of the glass can be seen through, but the furniture with a translucent glass top that has a metal part bonded to the lower surface of the glass feels hard and cold. There is no wood texture, and neither warm nor natural soft images can be shown.
Even in the case of wood furniture with translucent glass top, cushioning material and non-slip rubber material sandwiched between the wood leg and the glass can not see the upper end face of the wood leg, and the warmth of wood grain and wood surface which are characteristic of wood , I did not fully utilize the soft image of nature.
In addition, although there was a translucent glass top placed directly on the wood leg, light was reflected from the lower surface of the glass top, and the upper end surface of the wood leg was difficult to see.
The present invention is a furniture made of wood utilizing the warm and natural soft image that is characteristic of wood by making translucent grain glass transparent so that wood grain, wood surface and shape of wood can be clearly seen. Aim to further enhance the goodness of

The upper surface of the wood leg is directly bonded to the lower surface of the translucent glass using a translucent adhesive. Thereby, the upper end surface of the wood leg becomes visible through the translucent glass and the translucent adhesive.
Translucent glass refers to see-through glass that can transmit light including colorless and transparent, smoked, colored or milky white, and can see the other side through glass. Silica glass, soda lime glass, borosilicate glass Besides mineral glass such as acid glass and quartz glass, organic glass such as acrylic resin, metallic glass, etc. are also included.
The glass top refers to the table top made of glass, the top of a desk, and the seat of a chair. Glass top furniture is furniture which is a glass top.
It is recommended to use wood that is sufficiently dried and that does not easily expand or contract due to changes in humidity, or that does not crack or chip.

The adhesion is preferably from the strength surface as the leg to the end face as the end face, but it is not limited to the end as long as the strength can be maintained. In addition, a mokuguchi side means the cross section of the direction perpendicular | vertical to the vertical axis of the trunk of a tree. A board surface and a grid surface refer to a cross section in a direction parallel to the longitudinal axis of the trunk of the tree.
The light-transmissive adhesive is an elastic adhesive that retains elasticity even after bonding and drying. Moreover, although a liquid adhesive may be used, a sheet-like adhesive may be used. The elastic adhesive refers to a material that exhibits rubber-like elasticity after curing and has the property of dispersing internal pressure from the adherend. There are those based on silicone and modified silicone polymers, etc. and also have the function of absorbing external stress of vibration and impact.

The present invention according to claim 2 is a glass top furniture in which the upper end surface of the wood leg having an annual ring is bonded with a light transmitting adhesive, and the adhesive surface of the upper end surface of the wood leg to be bonded is based on a log. Concentric rings appear on the surface of the upper end. Some tree species do not clearly show annual rings.
Hardwood logs are relatively resistant to cracking, so logs are often used as they are. Since conifers are relatively easy to be broken, logs may be manufactured by inserting and bonding another tree to the split or broken portion of the log, or by cutting out the center of the log and inserting another tree.
In addition, after the log is dried well, the log is divided into two or four or more sectors, and the cut surface is smoothed and then bonded to form a laminated material, which may be a wood leg having concentric annual rings. .
In addition, it is possible to make a round-shaped lumbering material by rounding a square laminated lumber, and an annual ring appears on the surface of the mokuguchi. However, they are not necessarily concentric.

  The present invention according to claim 3 is a glass top furniture using a tree branch in which a branch tip is divided into three or more branches in a leg, and the end face of the divided tree branch is adhered to the lower surface of the glass top It is.

By adhering the lower surface of the glass and the upper end surface of the wood leg with a translucent adhesive, the glass and the translucent adhesive are optically integrated, and an optical reflecting surface cannot be formed between the mouth and the upper surface of the glass. It looks as if the wood grain of the upper end of the leg floated on the.
Also, from the top surface of the glass top, through the translucent glass and translucent adhesive, you can clearly see the grain and the shape of the tree, while taking advantage of the features of wood, warmth and natural image, It also has a beautiful, attractive furniture structure with good contrast.
If you do not use translucent dressing and just place translucent glass on the legs, air will enter between the glass and the tree, and light from the glass surface will reflect the annual rings and the bark. .

  According to the present invention of claim 2, the annual rings on the upper end face of the wood leg look fine, giving a warmth and a natural feel. In particular, round-shaped lumber with concentric rings is reminiscent of standing trees and has a different image than previous furniture.

In the present invention using the tree branches divided into three or more parts according to claim 3, each leg is fixed to the glass surface at three or more points. Can maintain a sense of stability.
In addition, since the three branches are not sawn, the mouth has a rounded natural shape with annual rings, and a table or desk feels like a top plate on the tree. In addition, if you are sitting on a chair, you will feel as if you are sitting on a tree.

Embodiment 1 is shown to FIG. 1, FIG. Four log legs 2 are bonded to a square translucent glass top 1 with an elastic translucent adhesive 3.
The wood leg 2 uses wood that is sufficiently dried and has no cracks or chips, but it is better to use a moisture-proof coating or a paint that is resistant to moisture in order to minimize expansion and contraction due to changes in humidity.
When the thickness of the elastic translucent adhesive 3 when cured is 0.5 mm or more and 1 mm or less, it becomes easy to cope with expansion and contraction due to a change in the humidity of the wood legs. When it becomes 1 mm or more, it becomes unfavorably inferior in terms of strength and requires time for curing.

When a force is applied in the lateral direction at a position close to the floor surface of the wood leg 2, a considerable force is applied to the adhesion surface of the leg. Therefore, the adhesion area is squared the size of 1/10 of the leg length. That is, it is good to set it as 2 times or more of the area of (1/10 of leg length) x (1/10 of leg length).
The formula is (leg length / 10) × (leg length / 10) × 2 ≦ adhesion area.
For example, if the length of the leg is 30 cm, 3 cm × 3 cm × 2 = 18 square cm or more, and if the length is 40 cm, 4 cm × 4 cm × 2 = 32 square cm or more.

From the viewpoint of strength and beauty, the wood legs 2 should be integrated (one piece) from the adhesive surface to the floor (where the furniture is placed), but the legs cannot be removed. Take place.
Therefore, the legs may be cut at the bonded lower part of the wood leg 2-1 shown by the broken line in FIG. 2, and may be attached and removed by a metal screw or the like. At this time, by setting the length of the wood leg 2-2 bonded to the glass to a half of the diameter or the width, the dimension in which the metal screw is embedded can be secured.

The upper end surface of the embodiment of the processed wood leg is shown in FIG. 3, FIG. 4 and FIG.
In A of FIG. 3, the back split embedding material 4 of another tree is inserted and adhered to the back split of the log, and the change of the wood leg due to the humidity can be suppressed to a small value.
In B of FIG. 3, the center of the log is cut out and another wood insert 5 is cut out and inserted into the log 6 and adhered. Since coniferous logs such as cedar are easy to break, A and B are processed to prevent cracking and chipping.
C in FIG. 3 is a hardwood log, and is relatively difficult to crack, so it can often be used as it is.
Moreover, the adhesive strength can be increased by impregnating the upper end surface of the wood leg with a chemical solution or a resin to make it smooth.

In FIG. 4, after the log is dried well, D is divided into two, E is divided into four sectors, F is divided into six sectors, and the divided cut surfaces are smoothed and then bonded. It is hard to crack while leaving concentric tree rings with laminated wood that is made by bonding logs after drying.
When the entire leg is impregnated with chemicals or resin or injected under pressure, the strength increases, the expansion / contraction due to humidity decreases, and the possibility of peeling off the adhesive or removing the leg decreases.

G in FIG. 5 is an aggregate of square timber, but leaves a log shape of appearance. H and I of FIG. 5 are assembled lumbers.
Adhesive strength with the glass top can be increased by compressing and compressing, fixing the shape by heat treatment, and smoothing the adhesion end face. In addition, the expansion and contraction due to the humidity are reduced, and the possibility of peeling off of adhesion and removal of the legs is also reduced.

  FIG. 6 shows a cross-sectional view of the leg 2 of the first embodiment. The hollow leg 2-3 of the wood leg is to lighten the entire table and to reduce stress load when the leg is inclined.

FIG. 7 shows the second embodiment. The fork is attached to the glass surface, with the fork branch on the leg and the branch being split up as if the tree had grown. This broadens the range of bonding positions and is strong against lateral stress.
The total adhesion area of the three-tree end is approximately the diameter of the inscribed circle of the triangle with three points at the center of the junction of the three-way branch divided by "1/10 of the leg length" , “A bonded area in the case of one wooden leg” may be divided by the area.
The equation is ((leg length / 10) × (leg length / 10) × 2) ÷ (inscribed circle diameter ÷ (leg length / 10)) ≦ adhesion area.
For example, if the leg length is 30 cm and the inscribed circle diameter of the trifurcated branch is 12 cm, (3 cm × 3 cm × 2) ÷ 12/3 cm = 4.5 square cm.

  The present invention can be used not only as a table, a desk, a shelf, a chair, etc., but also as a table for audio equipment etc., a furniture such as a decoration wall, a floating floor etc.
