Description

[Detailed description of the invention] [Technical field to which the invention belongs]

 The present invention relates to a bed that is adjustable in elevation so that a user can lean on it comfortably, and that is light and convenient.

[Prior art]

 The conventional elevation support structure of a bed is mainly composed of a connecting table 1 ', an active table 2', a locking unit 3 'and a separating sheet 4' as shown in FIGS. One side of the base 1 'is provided with a joint 11' for assembling with the bed frame, and the other side is provided with a fitting and connecting part 12 '. Is installed on the other side, an adjusting part 22 'is installed on the other side, and several stop teeth 221' are installed on the outer edge of the adjusting part 22 ', and one side of the adjusting part 22' The contact sheet 222 'is set. Also, a locking portion 31 ′ corresponding to the pawl 221 ′ is projected from one side of the locking unit 3 ′, and a spring 32 ′ is further connected to the locking unit 3 ′ so that the locking portion 31 ′ has elasticity of the spring 32 ′. To engage with the pawl 221 '. The separation sheet 4 ′ is installed on the adjustment unit 22 ′ of the activity table 2 ′, a contact part 41 ′ leaning on the contact sheet 222 ′ is installed on one side, and a stop tooth 221 ′ is provided on the outer edge. A pusher 42 'is provided which slightly exposes the outer edge and abuts against the top edge of the locking portion 31' of the locking unit 3 '. As shown in FIG. 13, when used, the coupling table 1 'and the activity table 2' are assembled on the bed frame 5 'and the activity frame 6' of the bed, respectively. The activator 2 'is actuated, and the pawl 221' at an appropriate position and the locking portion 31 'of the locking unit 3' are locked and positioned, thereby raising the bed frame 5 'above the front part. The angle is adjusted, and the pawl 221 'and the locking portion 31' are locked to support the weight when the user leans. When the activity table 2 'is largely moved in the direction of the coupling table 1', the contact sheet 222 'comes into contact with the contact section 41', and the separating sheet 4 'corresponds to the operation of the activity table 2'. The pushing part 42 'is brought into contact with the top edge of the locking part 31' of the locking unit 3 ', and the tip of the locking part 31' is pushed down to operate the activity table 2 'in the opposite direction.

[Problem to be Solved by the Invention] However, the above-described conventional structure is a multi-stage adjustment in which the positioning is performed after the locking, so that the adjusted elevation angle of the bed frame 5 'cannot be applied to each user. In addition, it is inconvenient for an elderly person or a physically handicapped person to adjust the elevation angle of the bed frame 5 'after getting out of the bed, and when adjusting the bed frame 5' to return to a horizontal state. Since the front teeth of the bed frame 5 'must be largely bent and the set teeth 221' must be disengaged from the locked state with the locking portions 31 ', the operation becomes more difficult. In addition, a general bed has a motor structure (not shown in the figure) installed under the bed, and a telescopic rod is connected to the motor and the length of the telescopic rod is extended by the motor to increase the elevation angle of the bed. I am adjusting. However, the above-mentioned structure and the motor cannot be operated without power, so that the place where the bed is used is limited. Also, since the motor has a large volume, a large weight and a high cost, the bed has the disadvantage that it is not lightweight and economical. Therefore, an object of the present invention is to provide a bed which can easily adjust the elevation angle when a user leans on the bed and has excellent usability, operability and light weight.
