Description

Detailed explanation of the device

The present invention is a table for a chair with a relatively narrow top used in a small room, etc., the legs can be folded and moved to obtain space if necessary, and the storage is not bulky. It's about tables.

A so-called folding leg table is widely used in which the legs on the back surface of the top plate are raised to be used as needed, and when the legs are not used, the legs are put along the back surface of the top plate for storage.
In a place where a large number of people gather, for example, in a folding leg table used in a meeting place such as a public hall, a conference room, etc., a considerable number are used at the same time, and the legs are used as a top plate in order to reduce the total volume for storage. It is designed to fold in the same plane on the back side without unevenness and to stably respond to stacking multiple layers. Therefore, there were restrictions such as the leg length being less than half of the top plate length.

On the other hand, the folding table for chairs used in ordinary households is smaller than that for conferences and has rounded corners at the four corners of the top plate for aesthetics and safety, and the legs are the same as the top plate. It is made of wood and has a character as a furniture, and the position of its top plate is configured to be high with the life of a modern chair. The legs are longer in order to make the top higher, and if the dimensions of the top are small, that is, in the case of a top with a small area, the folded legs do not fit within the length of the top and overlap with the back side of the top. It is conceivable that the tip part of the lever protrudes. The folding legs are provided on the back surface of the four corners of the top plate, and they fold in the length direction of the top plate or in the center direction of the top plate on a diagonal line, so that the folded legs do not overlap. Each leg is limited to being within about half the length of the top. In the case where four legs are folded diagonally toward the center of the square top plate, the four legs are erected independently, but each leg is firmly attached in consideration of the rotation during folding. It is not practical because it requires a structure and wobbles in the legs after long-term use. Therefore, here, two legs on one side of the top board are connected to increase rigidity and the folding leg table has a strong structure. Therefore, a 4-fold independent folding type is not considered. Since such a folding leg table is for home use, it does not need to be considered for accommodating and stacking several similar tables, but when storing it upright, one leg part can be stored. However, it is aesthetically unpleasant to open and close without going over the top plate, and it is possible that it takes up space and is caught when walking. Various techniques have been proposed (Patent Document 1) in which the legs of the folding leg table are changed to be long when in use and short when not in use in order to accommodate the legs in the range of the top plate (Patent Document 1), but the structure is complicated. However, if the frequency of use is low, an excessive mechanism is adopted, which is not practical. The technology applied to the folding leg table of the present invention is to use it as a general table at all times, and to fold it only when it is necessary to remove it and move it with minimal volume without touching interior furniture. In addition, it is a structure that has a relatively small appearance at the distribution stage, when purchasing and bringing it back, etc. It is considered that the structure disclosed in the present invention can solve the problem in consideration of the necessity of providing the function which is not always used in such a complicated manner as in the prior art and the economical efficiency.

JP, 2013-248318, A

With a general square top plate, the two legs on the short side of the square have an integrated structure. When moving or storing the table, when the top plate is wide, that is, the long side of the top plate There is no problem if the length is more than twice the length, but in the case of a small table used in a narrow space, the long side of the top plate is provided to face the back side of the short side of the top plate. It may be less than twice the length of the leg, and in this case, when the leg is folded due to the necessity of movement and storage, the leg tips may overlap. One leg is along the top plate, but the tip of the leg folded afterwards overlaps with the previous leg, and the tip projects at an angle. Even if it is stored in this state, there is no big problem just by taking a little space, but if you leave it close to you and store it, you will touch the protruding legs during walking and the table will collapse, and other furniture, floors, etc. There is a concern that it will hurt you or strike your foot.

According to the present invention, the folding legs are provided at the four corners of the back surface of the tabletop used at home, and the two legs located on one side of the rectangular tabletop are connected to form an integral leg structure for moving or storing the table. In the case of, each of the opposite folding legs is folded and put on the back of the top plate, even if the length of the folding leg on one side is more than half the length side of the top plate, it is folded first. Disclosed is a structure for accommodating the tip of the other leg on the one leg so as to overlap the tip of the other leg to eliminate the protrusion. There are two methods for this leg overlapping structure. One is for folding the other by folding the position of the pivot hinge axis of one side folding leg base by the thickness of the folding leg. The height of the rotation base point changes, which solves the problem. That is, the rotation axis of one leg is near the back surface of the top plate, and the rotation axis of the other leg is farther from the back surface of the top plate by the thickness of the leg. The leg which is pivoted by a hinge near the top is placed near the back of the top, and the tip of the other leg overlaps on it. The hinge for pivoting the legs is composed of a top plate metal fitting fixed to the back surface of the top plate and a leg metal fitting fixed to the leg part rotatably connected by a rotary shaft. For the hinge of the other leg apart from the back surface, use the one with a long top plate metal fitting, that is, the state that it is installed upright on the back surface of the top plate so that the position of the rotation axis is Will be farther away. Therefore, both legs can be superposed in parallel with the top plate. This rotation of the legs requires a sequence of operations, and it is necessary to first rotate the legs having a rotation axis close to the top plate. Also, by lengthening the top plate metal fitting, when the legs rotate to support the top plate in a right angle state, when the legs are rotated, a gap is created between the leg ends and the top plate, so that the hinge When fixing the leg fittings and legs, it is necessary to shift the fixing position by this gap.

The second method is that the position of the rotating hinge shaft is the same, and the leg fitting on one side is fixed by arranging and fixing the auxiliary material for the thickness of the leg between the leg fitting to be fixed and the leg. Even if the hinge shafts of both legs are in the same position, by rotating the leg on which this auxiliary material is placed later, the thickness of the auxiliary material eliminates the height of the previous leg and Is a polymerization of. Further, the same effect can be obtained by lengthening the length of the leg fitting of the rotating hinge by the amount of the auxiliary material described above. This rotation of the legs also requires a sequence of operations, and it is necessary to first lay out the auxiliary material or fold the legs without using long leg fittings.

As described above, by adopting the connection configuration of the top plate and the leg portion having the configuration disclosed in the present invention, the folding leg table can be stored safely and easily. The hinge metal fittings have the same mechanism, and it is easy to prepare two types with different dimensions, and no new member is designed and prepared. It is also easy to use plywood, which is a material used for the top plate, legs, etc., as an auxiliary material, and the same effect can be obtained without selecting a new material.

1 is a perspective view showing an embodiment of a folding leg table according to the present invention. 1 is a side view of a first embodiment of the present invention. It is a perspective view showing the details which lengthened the top plate metal fitting of the 1st example of the present invention. FIG. 5 is a perspective view showing details of the auxiliary material of the second embodiment of the present invention.

Embodiments of the present invention will be described below. The present invention is a folding leg table, which is roughly composed of a top plate 1, legs 2, and a hinge part 3 that rotatably connects the top plate 1 and the legs 2. The top plate is a substantially square or elliptical shape with rounded corners. Four legs are arranged on the back surface of the top plate 1 in an upright state, but the bases of the two legs on the side of the top plate 1 substantially square side are connected by a leg connecting plate 22 to be integrated. The leg portion 2 is formed in a substantially gate shape. The top plate 1 and the legs 2 are connected by a hinge 3. Two hinges 3 are arranged on each leg 2 at both ends of the gate shape close to the legs 21. Further, the configuration is such that the top plate metal fitting 31 attached to the top plate 1 and the leg metal fitting 32 attached to the leg portion 2 and the rotating shaft 33 serving as a pivot shaft for connecting the both, and a state in which the legs support the top plate, That is, the fixed shaft 34 is arranged to maintain and fix the hinge portion 3 in the state of being opened at a right angle. If the fixed shaft 34 is attached to one of the two hinge portions 3 arranged on the one leg portion 2, the purpose will be sufficiently achieved. The top plate fitting 31 that constitutes the hinge part 3 is bent to have a substantially U-shaped cross section, and one end and one end of both sides of the U-shape are bent outward at right angles to the top plate. 1 Screw holes for mounting are arranged. Further, the other end of each side is provided with a hole through which a rotary shaft 33 for connection with the leg fitting 32 is inserted, and the central part is provided with a perforation for bridging support of the fixed shaft 34. The attachment to the top plate is to place the folds at one end of the U-shape and one end of both sides on the top plate and fix them with screws.

The leg fitting 32 has a bottom side wider than the U-shaped width of the top plate fitting 31 described above, and its side has a substantially U-shaped cross section that overlaps the outside of the side of the top board fitting 31. A plurality of screw holes for mounting the leg portion 2 are arranged, holes are formed in the central portions on both sides, and the hinge portion 3 is rotatably coupled by the rotating shaft 33 through the connecting holes at both side edges of the top plate fitting 31. Make up. Further, the tip ends of both sides are arcuate, and the fixed shaft receiving groove 35 is cut out in a U shape at the tip of one side, and the top plate fitting 31 described above is inserted into the groove in a bridging state. , The end of the fixed shaft 34 protruding toward the fixed shaft receiving groove 35 is received. The attachment to the leg portion 2 is performed with a screw hole at the bottom.

The top plate 1 and the legs 2 connected by the hinge part 3 having the above-described structure are used. However, when the table is used normally, that is, when the two legs 2 support the top plate 1, both of the hinge parts 3 are supported. The metal fittings 31 and 32 are in a state where their U-shaped bottoms face each other, and the tip of the fixed shaft 34 is fitted into the fixed shaft receiving groove 35 of the leg metal fitting 32 to control the free rotation of both metal fittings 31 and 32. Is what you are doing.

The Example of this invention is shown. In the first embodiment, two of the four hinges to be used have long top metal fittings 31 of the hinge portion 3, that is, both side edges and U-shaped metal fittings fixed to the top board 1. Use a leg whose bottom is as long as the thickness of the leg. This long top plate fitting 31 is used only for the leg portion 2 on one side. Therefore, when the leg fitting 32 and the pivot shaft 33 are connected and assembled as the hinge part 3, the position of the pivot shaft 33 is different. That is, the distance from the back surface of the top plate 1 is separated from the position of the pivot shaft 33 of the hinge 3 of the other leg 2 by the thickness of the leg. Therefore, if the legs 2 using the short top metal fittings 31 are first folded, and then the legs 2 using the long top metal fittings 31 are folded, the legs are parallel to the back surface of the top 1 without contacting each other's legs. , It is possible to systematically stack the legs. By lengthening the top plate fitting 31, when the legs 2 rotate to support the top 1 at a right angle, a gap is left between the ends of the legs 2 and the top 1 as it is. Therefore, when fixing the leg fitting 32 of the hinge part 3 and the leg part 2, it is necessary to shift the fixing position by the gap. The same effect can be obtained by using four hinges having the same specifications and incorporating an auxiliary material or the like for the thickness of the leg between the top plate fitting 31 of one leg 2 and the top plate 1. ..

In the second embodiment, the same four hinges 3 are used, and the auxiliary member 4 is interposed between the leg fitting 32 and the leg connecting plate 22 of the leg 2. The auxiliary member 4 is made of plywood or the like like the top plate and legs, and has the same thickness as the legs. Therefore, when the two legs 2 are folded, parallel stacking thereof is possible. For the same purpose as this method, the same effect can be obtained by using the leg fitting 32 which is made longer by the thickness thereof instead of the auxiliary member 4.

No matter which of the above configurations is adopted, since the legs overlap each other when the legs are folded, there is no protruding portion when the legs are stored, and the furniture is not damaged or the walking is disturbed.
