Description

  The present invention relates to a table having high strength, and for example, relates to a table configured not only to have a strength that is not easily broken even in the event of an earthquake disaster, but also to have a light weight that can be used as normal furniture.

Most tables used for dining and the like in ordinary homes are made of wood, and some products use glass or the like for the top plate, but in any case, the strength is not so strong.
On the other hand, in Japan, the threat to the earthquake is increasing, and it has been conventionally recommended to hide under a table as a way of dealing with the disaster. The actual situation is that the table used in can't expect that much strength.

  As a method of increasing the strength, it is conceivable to configure the table with steel, but in general, steel furniture is very heavy. For example, many steel desks for business use have a weight of around 100 kg, and the table is made of steel. It is not suitable as a table used for dining etc. for general households.

Also, there is an idea to make a desk etc. with aluminum, but the aluminum itself is considerably weaker than steel, and when you assemble the aluminum top plate and the same aluminum leg using bolts etc., There is a problem in strength, and a conventional example in which a high-strength table is actually formed using aluminum is not known. .

  The present invention provides a table that has a weight that is easy to use as a home table, but has a much higher strength than a normal wooden table for home use, and is not easily broken even if it encounters an earthquake disaster or the like.

  The present invention constitutes a table by bending a single aluminum plate. This table is composed of a pair of opposed plate-like leg portions and a top plate portion, and this leg portion is formed by bending a portion corresponding to the edge of the top plate portion on the aluminum plate by 90 degrees. The leg portion comprises and comprises a bottom edge portion and a pair of opposing side edge portions.

  Here, each side edge part has a first side edge part formed by bending 90 degrees toward the other leg part facing each other, and a tip part of the first side edge part is connected to the inside of the table. The second side edge portion is formed by bending 90 degrees toward the head, and the tip end portion of the second side edge portion is bent 90 degrees in the direction opposite to the other leg portion. And a third side edge portion.

  Further, the bottom edge portion of the leg portion is formed by bending the first bottom edge portion by 90 degrees toward the inside of the table, and the front end portion of the first bottom edge portion is directed toward the top plate portion. And a second bottom edge portion formed by bending 90 degrees.

  Further, the top plate portion includes a pair of opposing side edge portions, and each side edge portion includes a first side edge portion formed by bending 90 degrees downward, and the first side. A second side edge portion formed by bending the tip portion of the edge portion 90 degrees toward the inside of the table, and by bending the tip portion of the second side edge portion 90 degrees toward the top plate portion. It is comprised from the comprised 3rd side edge part.

  An upper end portion of each side edge portion of the pair of leg portions is welded to a second side edge portion of the top plate portion, and a second bottom edge portion of each of the pair of leg portions. Are connected by one connecting bottom plate. As the aluminum plate, a material having a material of JIS standard A5052 and a thickness of about 3 mm is used.

  Reinforcing hardware is attached in the vicinity of the four corners inside the top plate portion, and a square pipe for reinforcing the top plate portion is attached to the back surface of the top plate portion, and the plywood for the top plate is further attached to the top plate. Attach to the front side of the part and strengthen it.

  Although the table of the present invention has a weight that is cheap to handle as household furniture, it has a much higher strength than a normal household table and is not easily broken even if it encounters an earthquake disaster or the like.

An embodiment of a table according to the present invention will be described below with reference to the drawings.
The table of this example is manufactured by bending a single aluminum plate cut into the shape shown in FIG. Here, in order to increase the strength of the table, the thickness of the aluminum plate is set to 3 mm, and an aluminum plate of JIS standard A5052 is adopted to prevent the occurrence of cracks during bending.

  In this figure, 1 corresponds to the top plate portion of the table, and 2 and 3 correspond to the leg portions. A table is formed by bending all the dotted lines in the figure at right angles. In addition, the size of each part in this figure is n = 1454mm, m = 617mm, h = 77mm, g = 712mm, k = 27mm, r = 37mm, s = 27mm.

Next, this bending process will be described with reference to FIG.
Each of the side edge portions 101 to 106 and 201 to 206 of the top plate portion 1 and the leg portion 2 in FIG. 12 is bent by 90 degrees inward as shown in FIG. In addition, the bottom edge portions 207 and 208 of the leg portion 2 in FIG. 12 are also formed by performing the operation of bending 90 degrees inward as shown in FIG. Next, the leg portion 2 and the top plate portion 1 are formed by bending the leg portion 2 by 90 degrees with respect to the top plate portion 1 as shown in FIG.

The side edge portions 301 to 306 and the bottom edge portions 307 and 308 of the leg portion 3 are also bent in the same manner as in the case of the leg portion 2, and then the leg portion 3 is bent 90 degrees with respect to the top plate portion 1. This forms the overall structure of the table. A perspective view of the table configured in this manner is shown in FIG.
In this way, since the table is formed by bending one thick aluminum plate, the table is manufactured by assembling the aluminum top plate member and the leg member using bolts or the like. Compared to the case, high strength can be obtained.

  In this figure, the upper end portions of the side edge portions 101 to 106 and 201 to 206 of the two leg portions abut against the side edge portions 102 and 105 of the top plate portion. Reinforcement is made by welding (for example, locations indicated by Y1 and Y2 in this figure), and a reinforcing bottom plate 4 is provided between the bottom edge portions 207 and 307 of the leg portions 2 and 3. Install. As a result, the strength of the table is higher.

  Here, this connecting bottom plate is also made of an aluminum plate having a thickness of 3 mm and JIS A5052. This manufacturing method will be described with reference to FIGS. A connecting bottom plate is manufactured by bending side edge portions 401 to 406 of the aluminum plate cut into the shape shown in FIG.

  FIG. 3 is a perspective view of the end portion of the manufactured bottom plate as seen from the back side. In this figure, the bottom edge portion 207 of the leg portion 2 of the table is inserted into the gap between the side edge portions 401 to 404 and 405 formed by bending, and the positions of the bolt holes 407 and 408 of the side edge portion 405 in FIG. Then, it is bolted to the bottom edge portion 207 of the leg portion 2. In such a state where the connecting bottom plate is attached, the side edge portions 401 and 404 of the connecting bottom plate are set so as to contact the floor surface.

  The connecting bottom plate also serves as a footrest when sitting on a chair and using a table. In this embodiment, although not explicitly shown in FIGS. 1 to 3, a striped plate having an infinite number of rough concavo-convex patterns formed on the surface is used as the aluminum plate for the connecting bottom plate. This makes it difficult for the foot to slip when the foot is placed.

When the load-bearing performance of the table configured as described above was examined, it was confirmed that no damage was caused even when an average load of 1200 kg was applied.
In addition, various reinforcement | strengthening means can be further provided with respect to the table of FIG. 1, and intensity | strength can be raised more. These reinforcing means will be described below.

First, as one method, the table can be greatly reinforced by attaching reinforcing hardware to the four corners on the inner side of the table and supporting the central portion of the back surface of the top plate portion with a square pipe. These reinforcing structures will be described with reference to FIGS.
FIG. 4 is a perspective view showing a state in which the reinforcing hardware is attached to one corner inside the table. The reinforcing hardware 5 is located at the positions of the screw holes 501 to 505 and the side edge portion 205 of the leg portion 2. And a side edge portion 105 of the top plate portion. The other three corners are similarly strengthened by attaching hardware.

  The reinforcing hardware is manufactured by bending a JIS standard A5052 aluminum plate shown in FIG. 5 at the dotted line. A perspective view of the manufactured reinforcing hardware is shown in FIG. When the reinforcing hardware is attached to the inner corner of the table, the bent piece at the top of the reinforcing hardware abuts on the back side of the top plate portion. From the front side of the top plate, fasten with a countersunk screw.

  Next, attachment of the aforementioned square pipe will be described. FIG. 7 is a plan view of the table to which the square pipe is attached as seen from directly above, and 6 indicated by a dotted line is a square pipe attached to the back side of the top plate portion 1. In this figure, reference numerals 601 to 604 denote countersunk screws that screw the square pipe 6 from the front side of the top plate portion 1. On the other hand, both ends of this square pipe are attached to the inside of the leg portion depending on the angle.

  This attachment method will be described with reference to FIG. This figure is a perspective view of a state in which one end portion of the square pipe is attached obliquely viewed from below, and by screwing with the screw holes 701 to 704 of the angle 7, the end portion of the square pipe 6 is attached to the leg portion. 2 firmly attached. In this embodiment, a stainless steel pipe having a diameter of 40 mm × 60 mm is used as the square pipe.

  As described above, the strength of the table is greatly increased by providing a plurality of reinforcing means, but the strength can be further increased by attaching a strong top plate to the front side of the top plate portion of the table. . FIG. 9 shows a front view of the table configured as described above. In this figure, 31 is a plywood for a top plate attached to the top plate portion, and is constituted by a plywood having a thickness of 25 mm.

  In FIG. 7, the attachment method is such that openings for inserting butterfly bolts are formed at positions 107 to 110 near the four corners on the front side of the top plate portion 1, and the back surface of the plywood for the top plate corresponding to this is formed. Embed nuts in four places. Then, the top plate plywood is attached by screwing the butterfly bolt from the back side of the top plate portion 1 to the nut embedded in the top plate plywood through the opening provided in the top plate portion. .

  By adopting the structure as described above, it is possible to realize a table that is not necessarily broken even if it encounters an earthquake or the like while using an aluminum plate that is not necessarily sufficiently strong. At present, an increasing number of homes are always equipped with emergency bags and emergency bags in case of a disaster. However, the table of this embodiment is equipped with a locking device for hanging such emergency bags. If it is provided inside, it is more convenient during disasters.

  A configuration example provided with such a locking tool is shown in FIG. This figure shows an example in which a horizontal bar is attached as a locking tool, and is a perspective view of a configuration example in which both ends of the horizontal bar are held by two opposing reinforcing hardwares inside the table. One end of the horizontal bar 8 is held on the reinforcing metal fitting 5 by a holding metal fitting 801, and this holding metal fitting 801 is attached to the reinforcing metal fitting 5 with three screws. As the horizontal bar, a stainless steel round pipe is used.

  In addition, it is not uncommon for a fire to occur at the time of a disaster, but in consideration of this, a fire extinguisher installation holder may be provided inside the table. FIG. 11 shows an example in which a fire extinguisher holder is attached to the inside of the leg portion 3 of the table. In this figure, the fire extinguisher holder 21 has four bolts attached to the leg portion 3 through bolt holes 211 to 214. It is attached by penetrating and tightening.

  As mentioned above, although the Example of this invention was described, this invention is not limited to this Example of course, Based on the technical idea of this invention, various structure modifications are possible. For example, the specific dimensions of the aluminum plate shown in FIG. 12 and the square pipe of FIG. 8 need not be limited to the numerical values described in the present specification, and may be changed according to the size of the table to be manufactured. is there. Also, the thickness of the aluminum plate need not be strictly 3 mm, and may of course be slightly increased or decreased.

  As for the reinforcing hardware attached to the inner corner of the table, as shown in FIG. 6, not only the upper bent piece is screwed, but also the bent piece contacting the leg portion 2 is screwed to the leg portion 2. Strength is increased. Further, the shape of the reinforcing hardware can be changed without being limited to the embodiment.

  For example, the upper part of the reinforcing hardware shown in FIG. 4 is elongated in the lateral direction along the side edge part 104 of the top plate part, and is fused with the reinforcing hardware attached to the side edge part 305 of the opposite leg part 3. Also good. That is, one reinforcing metal piece is screwed over the entire length of the side edge portions 205 and 305 of the two leg portions and the side edge portion 105 of the top plate portion. The upper bent piece of the reinforcing hardware is also screwed over the entire length of the upper bent piece on the front side of the top plate portion.

If it does in this way, the edge part of a top-plate part becomes a structure close | similar to a square pipe substantially, and intensity | strength increases very much.
In this embodiment, butterfly bolts are used to attach the top plywood, but bolts of other shapes can also be used. Moreover, although the horizontal bar is attached as a locking tool, it cannot be overemphasized that it is not limited to such a horizontal bar. Furthermore, the specific structure of the fire extinguisher holder is not limited to that of this embodiment.
