Description

Versatile bed

The present invention relates to a bed, and more particularly to a multi-use bed that can be used efficiently and versatile.

In general, a bed refers to furniture that a person can sleep in. The bed has a basic configuration consisting of a mattress having an area that can accommodate a human body and a frame supporting the same. However, since the bed should be spread widely in its structure, it takes up a lot of living space compared to other furniture, and becomes a limitation in arranging additional furniture.

Therefore, there is a great demand for the development of a multi-use bed that can utilize space so as to secure a wider living space and use it with other furniture even in a narrow place. On the other hand, to solve this, it is possible to fold during the day to secure a living space, can be transformed into other furniture and utilized, a folding bed having a structure that can be used as a bed to be wide open only at night is widely used.

For example, Korean Patent Publication No. 10-2011-0113545 discloses a folding bed, which will be described below with reference to FIGS. 1A and 1B.

Figure 1a is a perspective view showing an open state of a conventional folding bed, Figure 1b is a perspective view showing a folded state of a conventional folding bed.

As shown in Figure 1a, the configuration of the folding bed 30 is a plurality of mattress (10, 11, 12) and the frame (1, 2, 3) for supporting it, the amount of the frame (1, 2, 3) It consists of transverse links (4, 5, 6) and longitudinal links (7, 8, 9) coupled to the side, respectively. In addition, the frame (1, 2, 3) connected by a plurality of the lateral link (4, 5, 6) and the longitudinal link (7, 8, 9) consists of a configuration that is folded and stacked in three stages. And, as shown in Figure 1b, folded in the stacked state in three stages is made of a structure that can be used as a desk by removing the desk plate 13 from the inside of the top mattress 10. Here, various types of links 4, 5, 6, 7, 8, and 9 required to fold the folding bed 30 in three stages are connected in a complicated manner. If any one of the connection structure is broken or broken, there is a disadvantage that it can not perform its function properly.

In addition, the more devices involved in the folding function, which is an essential function of the folding bed 30, the greater the risk of failure and the noise generated by each device during sleep may interfere with a good night's sleep. In conclusion, when the folding function becomes impossible due to a failure or breakage, the use of living space is difficult to expect since it is no different from the existing bulky general bed.

Meanwhile, in order to deform the folding bed 30 to secure a living space or to transform it into a folded structure for use as a desk, the mattresses 10, 11, and 12 must be lifted and stacked. However, this can be difficult for children, women and the elderly to use because of the considerable force. However, using a device such as a spring to solve this point, even if there is an effect to relieve the force by inducing the movement in the folding or unfolding direction, the link (4,5,6,7,8,9) during the folding process Not only is there a risk of a safety accident in which hands and parts of the body can be pinched between the frame and the frame (1, 2, 3), but the risk of a safety accident is also anticipated in the process of preventing the refolding due to lack of force during folding. Done.

On the other hand, when folding the folding bed 30 completely folded in three stages to use as a desk, by removing the desk plate 13 inserted into the top mattress 10 is transformed into a desk can be used, the desk plate ( 13) does not have a structure to support the lower side of the shear can cause the phenomenon to tilt below the ground. For this reason, it is unstable to use the hand on the desk plate 13 in a comfortable posture, and there is a risk that books, notebooks, cups, etc. placed on the desk plate 13 will spill toward the user, and if excessive load is applied. There is a problem that the inner and outer parts of the uppermost mattress 10 that accommodates the desk plate 13 may be deformed and cause a malfunction.
