Description

[Detailed description of the invention] (Field of industrial application) The invention is attached to one side of the bed body, and the bed body can be extended in the longitudinal direction, and the angle of the extended part can be adjusted according to the purpose of use. This invention relates to a bed extension device having the above-mentioned structure.

(Prior art and its problems) Beds commonly available on the market include types such as single beds, semi-double beds, and double beds, which have a fixed length and only a different width.

By the way, there is no particular problem with the above-mentioned beds used by adults, but there are many types of beds available on the market for children who are growing up, and they generally need to be replaced as the child grows. There is.

However, traditionally, there are problems with economical waste and waste when it comes to replacing them, so in many cases people continue to use them as they are. It is causing new problems.

Therefore, in recent years, due to the above-mentioned circumstances, there has been a demand for the development of a bed or a bed extension device that can extend the length of the bed body as the child grows.

(Purpose of the invention) The present invention was devised to meet the needs in view of the above-mentioned actual situation, and can be used as is without discarding the conventional bed, and can be easily attached to one side of the bed main body. To provide a bed extension tool which can be freely extended along the longitudinal extension line and which can freely and steplessly adjust the angle of the extension part according to the purpose of use, such as in the case of injury or illness. It was created as a.

(Structure of the invention) That is, the bed extension tool of the invention is attached to one side of a conventional bed main body, which holds the lower part of the bed base with a support member and maintains the bed base at a constant height. The extension tool includes a pair of left and right fixing tools provided respectively on both sides of the upper edge of one side of the base of the bed main body, and a base part is pivotally attached to each of the fixing tools, and the extension tool has a longitudinal axis. A pair of pipes are provided with a notched groove across the entire lower surface, a wire mesh is stretched over the entire surface between the upper surfaces of these two pipes, and one side is inserted into each of the bottom sides of each pipe to form an extension line of the pipes. A telescoping shaft capable of expanding and contracting in the direction, a wire mesh stretched over the entire surface between the lower surfaces of both of these telescoping shafts, and a reinforcing shaft between the other ends of each of the telescoping shafts, and the height of the shaft is It is characterized by being comprised of a height adjustment mechanism that is adjustable and supported.

(Function of the invention) The present invention, configured as described above, brings about the following effects.

That is, since each base of the pair of pipes is pivotally connected to a pair of left and right fixtures provided on both sides of the upper edge of one side of the base of the bed body, the pipes can be tilted freely. In addition, since a telescopic shaft is inserted into the bottom of each pipe, it is possible to further extend the length of the telescopic shaft, and a height adjustment mechanism is provided at the other end of both telescopic shafts. Since the height of the extension can be varied steplessly, the angle of the extension can be changed arbitrarily depending on the purpose of use.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the bed extension device of the present invention will be explained in detail based on an embodiment shown in the drawings.

(Example) Fig. 1 is an explanatory diagram showing a state in which the bed extender of the present invention is attached to a conventional bed body and extended, and Fig. 2 is a plan view of Fig. 1, and Fig. 3 2 is an enlarged view of the cut end taken along the line A-A' in FIG. 2.

The bed extension tool of the present invention is an extension tool that is attached to one side of a conventional bed main body, which holds the lower part of the bed base with a support member so that the bed base can be maintained at a constant height. The extension tool has a pair of pipes 1 pivoted to a pair of left and right fixing tools 2 provided on both sides of the upper edge of one side of the base of the bed body, and a telescopic shaft 5 is fitted to the bottom side of each pipe. Insert,
A telescoping shaft 5 is inserted into the bottom side of each pipe, and a reinforcing shaft 9 is installed between the other ends of each telescoping shaft 5, and the height is adjusted by supporting the shaft 9 in a variable height manner at the bottom of both sides of the shaft 9. A mechanism 6 is provided, and a wire mesh 3 is stretched over the upper surface between each pipe 1 and the lower surface between each telescopic shaft 5.

The pipe 1 is made of metal, hard resin, or the like and has a fixed length, and its base is fixed to the fixing device 2 with bolts, wooden screws, etc., on both sides of the upper edge of one side of the base of the bed body. The pair of pipes 1 can be freely tilted by being pivotally attached to the pipes 1 with pins or the like.

The pipe 1 is provided with a notched groove 4 having a cross section of a semicircle or less over the entire lower surface in the longitudinal direction. Second, the resistance during sliding is made as small as possible.

The wire mesh 3 is formed by combining thin metal rods in a lattice shape, and is stretched over the entire surface between the upper surfaces of both the pipes 1 and between the lower surfaces of both the telescopic shafts 4. The means may be any arbitrary method such as welding or bolting.

The telescopic shaft 5 is made of metal, hard resin, etc. and has a diameter slightly smaller than the diameter of the pipe 1 and a constant length so that it is fitted into the bottom side of each pipe 1 and slidably expands and contracts, as described above. By providing the telescopic shaft 5, it is possible to further extend the length of the telescopic shaft 5.

The height adjustment mechanism 6 is disposed at the lower portions on both sides of the reinforcing shaft 9 installed between the other ends of the respective telescoping shafts 5 to support the reinforcing shaft 9 in a variable height manner,
The height adjustment mechanism 6 includes, for example, the shaft 9 having threaded portions bored at both ends thereof, and a height adjustment mechanism having an upper end fixed to each side end of the shaft 9 with a nut 10 and a male threaded portion provided at the lower part. A height adjusting shaft 8, a leg 7 having a female screw threaded inside to support the height adjusting shaft 8, and a lower end of the leg 7 that does not damage the floor. The angle of the extended portion of the pipe 1 and the telescopic shaft 5 can be changed arbitrarily only by rotating the leg 7.

(Operation of the embodiment) When using the extension tool of the present invention configured as described above, the fixing tool 2 is attached to the conventional bed body.
, and after moving the telescopic shaft 5 forward and backward to a predetermined length with respect to the pipe 1, loosen the nut 10 and rotate the leg 7 until it reaches a predetermined length.
All you have to do is tighten the 0, and the bed extension of any height and angle is completed.

(Effects of the invention) The bed extender of the present invention is structured as described above and can be easily attached to the conventional bed body, so that the length of the bed body can be easily extended as the child grows. By using the small bed as is, it is possible to eliminate the conventional problem of curving the back and waist, and also eliminate the problem of wasteful purchase of a new expensive bed. Ru.

In addition, the bed extender of the present invention can be adjusted to be slightly higher than the height of the bed body using the height adjustment mechanism, for example, when the extender part is made to be the user's head. Just set the angle to
It can also be used as a bed with variable angles when reading or caring for a sick person.Furthermore, if the extension part is used as the foot of the user, the height adjustment mechanism can be used to adjust the height of the bed body. It has the added value of being able to be used as a hospital bed by simply setting the bed so that it is slightly higher than the bed, allowing patients with swelling such as nephritis to sleep with their legs elevated. Furthermore, if it can be easily disassembled or contracted when not in use, and if it does not disassemble,
It is a useful item that has many other uses, such as being able to be used as a storeroom.
