Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a folding bed having a simple structure that can be folded into a mountain shape when not in use.

[0002]

[Prior art]

 As the folding bed as described above, there is a folding bed as shown in FIG. 10 which is made of a metal pipe (refer to registered utility model No. 300385). In this folding bed 101, an upper bed half 102 and a lower bed half 103 are pivotally attached in front of and behind a support leg 104, and these bed halves 102 and 103 are bent in a chevron shape to form a bed half 102. , 103, the horizontal base frames 105 are arranged so as to be parallel to each other with the supporting leg 104 interposed therebetween.

At the time of this folding, the lengthwise intermediate portion of the folding bed 101 is pulled up, and the upper half bed 102 is operated so as to approach the lower half bed 103. For pulling up the intermediate portion, the base portion of each base frame 105 is mainly held and a force is applied in the bending direction. This is because it is difficult for a woman, in particular, to exert a sufficient force required for bending, only by holding the U-shaped frame 106 attached to the side surface of the base frame 105 to prevent the futon from slipping off. However, in this type of folding bed 101, a spring is attached to the back surface to urge the folding bed 101 in the folding direction so that the folding operation can be performed easily, so that the folding operation is accelerated in a geometric progression. It's done quickly. For this reason, there is a risk that a hand may be caught between the base frame 105 and the support leg 104.

[0004]

[Problems to be solved and means for solving them]

 Therefore, the main object of this invention is to form a handle on the support leg so that the folding operation can be performed without loss and a small force can be sufficiently exerted, and the operation can be performed safely and easily. .

A means for this is a folding bed in which two bed halves are pivotally attached to the front and rear of a support leg so that they can be folded in a mountain shape, and the support leg is pulled up to the support leg to fold it. It is a folding bed formed with a handle for use in.

It should be noted that, in order not to get in the way when not in use, it is preferable that the handle can be folded into a storage state that does not project outward. For that purpose, for example, the handle may be formed by bending a hollow round pipe, and may be formed so as to rotate between two positions, that is, a storage state along the side surface of the bed and a use state in which the bed protrudes outward.

In addition, the handle is formed by bending a hollow round pipe into an inverted U shape, and one end of the handle is inserted into a holding pipe to hold the handle vertically slidably and rotatably. The fixing pin is inserted and fixed from the outside of the holding pipe into the L-shaped cut groove formed on the peripheral surface of the handle, and the handle is prevented from pulling out upward, and the holding state along the side surface of the bed and the outward direction. It is also possible to rotate between the two postures of the projecting use state.

Further, in order to enable the attachment of other necessary members and to improve the usability, the handle is attached to the upper part of the support leg via the attachment plate, and the table or the attachment plate is attached. It is advisable to form a mounting part for selectively mounting the futon slip-off prevention fence.

[0009]

[Action and effect]

 That is, according to the above configuration, the folding operation can be directly performed on the support leg via the handle. Therefore, even if the bed half has no base, the pulling force can be effectively exerted without loss. Further, since the handle is located outside the bed half, it is possible to prevent the risk of pinching the hand during operation, and ensure safety. In addition, if a spring is attached to the back of the bed to urge it in the folding direction so that the bed can be folded smoothly, the configuration can be utilized. In addition, the pulling force can be used efficiently, so the operation is simple.

When the handle can be folded into the retracted state as in the second aspect, it can be prevented from becoming an obstacle when it is not necessary.

If the structure therefor is carried out by rotating the handle as in claim 3, the operation is simple.

That is, according to the present invention, when the handle is folded, for example, when the handle is pushed down, the fixing pin is relatively moved at a portion extending in the vertical direction of the kerf, and then the handle is moved to the left or right. It is sufficient that the fixing pin is rotated to one side and the fixing pin is relatively moved at the portion extending in the left-right direction of the kerf. In this way, the handle does not rotate in the use state where the pulling operation is possible, and a simple and reliable operation can be expected.

Further, when the handle is attached through the mounting plate and the mounting portion for selectively mounting the table or the futon slipping-off prevention fence is formed on the mounting plate, the table or the futon slippage may be increased. It is not necessary to form a separate mounting part just for the fall prevention fence, and it is possible to obtain a folding bed that has a simple appearance and a good design, and is multifunctional.

【Example】

 One embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view of a folding bed 1. This folding bed 1 is formed by using a metal pipe, and two bed halves 2 and 3 are pivotally attached to the front and rear of the upper end of a support leg 4, I can fold it into a mountain shape. 2 is a partially cutaway side view showing the structure, and FIG. 3 is a side view in a folded state.

Each of the bed halves 2 and 3 is attached to the free end (the end in the length direction of the folding bed) of the base frame 5 having a U-shape in a plan view in the height direction of the leg frame 6 also having a U-shape. The middle part is abutted to form a T-shape in side view. Mats 7 and 8 are fixed on the base frame 5 of the bed halves 2 and 3. For the bed half 2 on the upper body side, a mat 7 having a built-in reclining mechanism is used. The above-mentioned leg frames 6 are made to engage with each other at the time of folding by varying the width dimension or shifting the mounting position with respect to the base frame 5.

In addition, at the lower end of the leg frame 6 of each of the bed halves 2 and 3, there is formed a first support means 9 which makes contact with the ground during folding so as to facilitate the folding operation. Second supporting means 10 is formed on the upper part to support the load by being grounded when folded. The first support means 9 and the second support means 10 may be casters or rollers.

In addition, each of the bed halves 2 and 3 is biased by the biasing springs 11 and 11 from the intermediate position in the longitudinal direction of the lower surface of the base frame 5 to the lower end portion of the support leg 4 in order to facilitate the folding operation. Is suspended. In FIG. 2, 12 is a V-shaped spring mounting member in plan view, and 13 is a bracket for fixing this to the inside of the base frame 5. Also, a set of holding rails 14 is attached to the base end side of the base frame 5 of the bed half 2 on the upper body side, and a tray 15 on which small items can be placed is held in a retractable manner. It is also possible to pivotally attach one point on the outer peripheral edge of the tray and hold it so that it can be pulled out and inserted freely by rotation.

The support leg 4 has a pivotal attachment portion 4 a at the upper end thereof, and as described above, pivotally attaches the base end portions of the bed halves 2 and 3 to the front and rear, and at least one side of the support leg 4 is provided. , The handle 16 is attached. The handle 16 is used for folding the folding bed 1, and is for applying (pulling up) force in the direction of the white arrow shown in FIG.

The handle 16 is constructed and attached as shown in FIG. That is, the handle 16 is formed by bending a hollow round pipe into an inverted U shape, and inserting and holding one end side thereof into a holding pipe 18 integrally fixed to a mounting plate 17. The mounting plate 17 is formed by bending a rectangular metal plate along the up-down direction and fixes the holding pipe 18 to one side in the left-right direction. The same pipe member 19 is fixed to the other side, and the pipe member 19 is formed by inserting the columns 20a and 21a of the rotary table 20 (see FIG. 1) and the futon slip-off prevention fence 21 (see FIG. 6). It is a mounting part for mounting. It should be noted that the mounting plate 17 may be curved in a circular shape without forming the holding pipe 18 or the pipe member 19 to form a holding hole into which the handle 16, the rotary table 20, and the futon falling-off prevention fence 21 can be inserted. In particular, when attaching the handle 16, a large force is applied during use, and therefore it is preferable to interpose the holding pipe 18 because the effect of reinforcement can be exerted. The support leg 4 may be fixed with a screw 22 through a through hole 17a formed in an intermediate portion of the mounting plate 17 in the left-right direction.

The handle 16 can be slid up and down and rotated in the holding pipe 18, and can be folded out of the way shown in phantom in FIG. FIG. 5 shows the configuration thereof. The fixing pin 23 is inserted and fixed toward the handle 16 from one point on the outside of the holding pipe 18, and the fixing pin 23 moves relative to the handle 16 which receives the insertion of the fixing pin 23. An inverted L-shaped cutting groove 16a is formed. As a result, as shown by the solid line in FIG. 4, the handle 16 in the used state protruding outward is pushed down and rotated to the left, so that the handle 16 can be folded into a storage state along the side surface of the bed. .

By setting the dimensions so that the handle 16 fits inside the mounting plate 17 as shown in the storage state, the rotary table 20 and the futon slip-off prevention fence 21 can be mounted on the pipe member 19 which is the mounting portion. This is convenient because it can be performed regardless of the posture of the handle 16.

FIGS. 7 and 8 are side views showing the first supporting means 9 formed on the leg frames 6 of the bed halves 2 and 3 described above. FIG. 7 shows the leg frames 6 of the bed half 2 on the upper body side. FIG. 8 shows the leg frame 6 of the bed half 3 on the lower body side. The first supporting means 9 of the bed half 2 on the upper body side is composed of rollers 24 and casters 25 which are mounted side by side in order from the bottom. The lower end of the leg frame 6 is located on the floor F when the bed half 2 is extended. A ground plane 6a for grounding is formed. The roller 24 does not turn, and it touches the floor surface F when the bed half 2 is extended and during folding, and does not touch when folding. On the other hand, the caster 25 is in contact with the floor surface F at the time of folding from the end of the folding operation. That is, the rollers 24 and the casters 25, which are arranged and fixed in order from the bottom on the same outer surface of the leg frame 6, are provided with a step on a plane parallel to the surface of the leg frame 6.

The first support means 9 of the bed half 3 on the lower body side is composed of a roller 26 that comes into contact with the floor surface F only when the bed half 3 is extended, and is attached to the lower end of the leg frame 6. The support shaft 26a of the roller 26 is moved outward.

The second support means 10 of each of the bed halves 2 and 3 is composed of one caster 27 and, as already shown in FIG. It is installed toward.

When the folding bed 1 is folded, each leg frame 6 is in a state as shown in FIG. 9, and the two leg frames 6 forming the first supporting means 9 attached to the leg frame 6 of the bed half 2 on the upper body side. A load is stably supported by the casters 25, 25 and the two casters 27, which are the second support means 10 attached to the leg frames 6 of the respective bed halves 2, 3.

In the folding bed 1 configured as described above, the folding operation can be performed directly on the support leg 4 via the handle 16. Therefore, even if the bed halves 2 and 3 do not have a base, the pulling force can be effectively exerted without loss. Further, since the handle 16 is located outside the bed halves 2 and 3, it is possible to prevent the risk of pinching the hand during operation and to ensure safety. As a result, the structure in which the biasing spring 11 is attached to the back surface of the bed so that the folding can be smoothly performed can be utilized. Moreover, the pulling force can be used efficiently, so operation is simple.

Further, since the handle 16 can be folded into the stored state, it can be kept out of the way when it is not necessary. Moreover, since the folding is performed by rotating the handle 16, the operation is easy. Further, the kerf 16a formed in the handle 16 is L-shaped, and the handle is prevented from rotating in the use state where the pulling operation is possible, so that a simple and reliable operation can be expected.

Further, since the mounting plate 17 for mounting the handle 16 is formed with the mounting portion (pipe member 19) for selectively mounting the rotary table 20 and the futon slipping prevention fence 21, the rotary table 20 and the futon slipping down It is not necessary to form a separate mounting portion only for the prevention fence 21, and it is possible to obtain the folding bed 1 which has a simple appearance and a good design, and which is multifunctional.
