Bed device with mattress slippage prevention function

Abstract

PROBLEM TO BE SOLVED: To provide a bed apparatus having a mattress slip preventing function. SOLUTION: A projecting surface section 15 is integrally formed on the side of a head board 14 on which is formed so that the end of a mattress 12 on a back bottom 11a abuts. A side slip preventing member 16 on which a side surface of the mattress 12 abuts is provided at the center of the bed apparatus 6. The inclination angles of the back bottom 11a and a knee bottom 11c can be grasped by angle scales of inclination angle indicating concave sections 20 provided along arcuate edges 16E and 16E of the side slip preventing member 16. A first locking groove 22 to lock an abutment section 21a at a position to be capable of abutting on a foot side end surface of the mattress 12 and a second locking groove 23 to lock the abutment section 21a in a laid state on the bottom 11 are provided at a vertical section V and a horizontal section H of a leg section 21b of a foot side mattress guard 21 provided at a foot bottom 11d of the bed apparatus 6.

Description

technical field [0001] The invention relates to a bed device capable of supporting a mattress on a bed device base plate so as not to slip no matter the base plate is flat or tilted, and has the function of preventing the mattress from slipping. Background technique [0002] Conventionally, a mattress placed on the bottom plate of a bed has a structure in which a U-shape and a hook-shaped mattress stopper bent on the foot side are inserted into a through hole in the bottom plate ( illustration omitted). That is, the mattress stopper is held so as not to fall off by the weight of the mattress placed on the base plate. [0003] Therefore, because the mattress stopper is easy to fall off, the applicant has previously proposed a mattress stopper 1 shown in Patent Document 1 (Patent No. 3516338) (see Figure 12 ), as a mattress stop with simple non-shedding structure. [0004] The mattress stopper 1 is formed by bending a rod-shaped member, and has a U-shaped abutting portion 1...

Problems solved by technology

[0007] However, if the U-shaped abutting portion 1a abutting against the end face in the longitudinal direction of the mattress stands on the bottom plate 3, and the mattress stopper 1 is packaged and transported while still maintaining the installed state, then the During the process, the mattress barrier 1 may collide with something outside and be damaged, and there is a problem that the mattress barrier 1 and the bottom plate 3 cannot be transported without being separated.

[0008] Also, even if the mattress stopper 1 as described above is provided on the side of the sole plate 3, no member having a function of preventing slippage can be found on the side of the bed.
