Description

[Detailed Description of the Invention] This invention relates to the provision of an assembly table that is easy to assemble and disassemble, and is especially convenient to store and carry.

In the past, various improvements have been attempted in this type of assembly table for the purpose of compact storage or easy transportation, and in fact, the production and use of various products has been greatly improved. It is something that is being done.

However, in such prior precedents, the structure of the assembly fitting itself is complicated in order to ensure reliability of folding or assembly, or the installation of the assembly fitting or the legs is complicated. On the other hand, in the case of an assembly table having a particularly simple assembly structure, there is a problem in that the top plate may wobble.

The assembly table according to the present invention was specially devised in view of the inconveniences of the conventional tables, and it aims to simplify the assembly fittings themselves and at the same time reduce the complexity of assembly and disassembly. Also, the top plate to be assembled is linearly fixed using relatively long horizontal rods on the legs, which effectively prevents the top plate from wobbling. .

The assembled table of the present invention, in order to effectively utilize these various characteristics, is particularly characterized by its configuration comprising a pair of mounting fittings a, a' formed by pivotally connecting rising back plate portions 1a, 1a' of a pair of trough-shaped fittings 1, 1' having U-shaped side end surfaces at their side edges, a table top b...b' divided into a plurality of leaves, and a pair of leg frames 2, 2' each having a horizontal rod portion 2a bent on both sides to form leg rod portions 2b, 2b, which are attached to the frame 2,
A pair of mounting brackets a, a' are attached to the bottom surface of the divided table tops b, b' by attaching a bottom plate portion 1b of one of the brackets a, a'.
On the other hand, the metal fitting 1' is attached to the bottom plate 1'b.
The other two are attached to the underside of the top plate b' so that they face each other, and then the horizontal rods 2 on the legs c are
The fittings 1, 1' are fitted so that the fittings 2a, 2a' are respectively fitted between the fittings 1, 1', and the screw rod 3, which is screwed into the upper plate portions 1c, 1c' of the fittings 1, 1', is placed at a point where it is pressed against and engaged with the surfaces of the fitting rod portions 2a, 2'a. The following specific examples and corresponding design changes accompanying these examples are intended.
A typical embodiment of an assembly table according to the present invention will now be described with reference to the accompanying drawings, in which aa' denotes a pair of mounting brackets, bb'...b denote a tabletop divided into multiple leaves, and c denotes a leg, with the tabletop b typically being divided into two leaves and leg c in this case being one leg. When the tabletop b is divided into three leaves as in the embodiment in Fig. 3, leg c is made up of two legs, the central tabletop b' is the fixed part, and the left and right sides b, b" are configured to be folded onto the tabletop b'.

First, the mounting bracket a used for assembly.
is a pair of gutter-shaped metal fittings 1, 1' whose side end surfaces are U-shaped.
The joining edges of the respective upright back plate parts 1a, 1'a of these gutter-shaped metal fittings 1, 1', especially when the metal fittings 1, 1' are connected to form a series of gutter shapes. A pivot 4 is provided at the upper part of the joint edge (as shown in Fig. 4) to make it foldable, and holes for wooden screws 5 are provided in the mounting bottom plates 1b and 1'b, respectively. Threaded rods 3, 3 are provided on the plate parts 1c, 1'c, and the knobs of the screw rods 3, 3 are inserted into the holes 6, 6 in which the metal fittings 1, 1' are accommodated when folded. It was designed to be opened at c.

Next, the leg c is typically formed by bending both sides of the horizontal rod portion 2a in approximately the same direction to form the leg rod portions 2b, 2b.
It was separately planned that the ends b and 2b would be further continuous to form annular legs, and the leg frames 2 would be made into a pair with a pivot support 7 that could be folded freely in the leg rods 2b and 2'b. It was constructed as follows.

Mounting brackets a,
The metal fittings a' are mounted so as to span the top plates b and b', and are positioned facing each other on the sides of the top plate with the openings inside.First, the metal fittings a,
With the opening surface of a' on the inside, one metal fitting 1 is placed on the bottom surface of the top plate b, the other metal fitting 1' is placed on the bottom surface of the top plate b', and the bottom plates 1b and 1'b are placed on the top plate surface, respectively. By attaching them in close contact with each other with the wooden screws 5 to 5, the top plates b and b' can be folded freely at the four pivot positions of the metal fitting a, and there is no obstacle when folding the top plates b and b'. The knob portions of the screw rod 3 are designed to fit into the holes 6, 6 of the other metal fittings 1, 1', respectively.

In this way, the top plate b, which is integrally supported and connected,
While adjusting the expansion or contraction of the leg c at its pivot position 7 with respect to The metal fittings 1 and 1' are fitted into the U-shaped troughs, and the screw rods 3 are tightened to tighten the metal fittings 1 and 1', thereby integrating the metal fittings a and leg c.

The assembly table according to the present invention has a characteristic structure as described above, in which gutter-shaped metal fittings 1 and 1' whose middle side end surfaces are U-shaped are foldably supported, and these metal fittings 1 and 1' are mounted on a ceiling. By attaching them to the plates b and b' separately, the pivots of the top plates b and b' can be integrated, and the fixation of the top plates b and b' can be achieved by fitting the metal fittings 1 and 1' together. It is assumed that only the horizontal rod part 2a of the leg c to be
In addition, the leg c is attached only by fitting the horizontal rod portion 2a into the gutter-shaped metal fittings 1, 1' and tightening the screw rod 3, thereby achieving specific effects on the above-mentioned characteristics. It is.

That is, the metal fittings used for assembly and disassembly are simply the mounting metal fittings a, which simplifies the structure of the metal fittings, and also fixes the legs c using only the screw rod 3 and the gutter-shaped receiving part. By eliminating the use of any other support material, it is possible to reduce parts costs and assembly costs effectively.

Next, the attachment and detachment of the leg c is only performed by fitting the leg horizontal rod portion 2a into the gutter-shaped metal fitting receiving portion and screwing the screw rod 3, and therefore, easy and quick attachment and detachment are particularly guaranteed.

In addition, the metal fittings 1, which are relatively long for fixing the top plates b and b',
Since the leg horizontal rod part 2a is engaged and fixed in the gutter-like part at 1', the top plates b and b' receive relatively long linear support on both the left and right sides. , and leg c, any looseness in the installation is reliably prevented.

Furthermore, when folding for storage or carrying, the top plates b, b'...b can be folded freely, and the legs c can also be folded as separate pieces, minimizing the space required by these table parts. It could have been reduced.

Because of these features, the table is not only useful in everyday life, but is also particularly effective as an outdoor item in the mountains, fields, and beaches. This was considered to be a hole.
