Description

Bed mattresses {MATTRESS FOR BED}

The present invention relates to a mattress for a bed, and more particularly, to a bed mattress that can suppress the vibration of the spring member to be transmitted to the adjacent spring member and to facilitate the replacement of parts.

In general, a bed mattress is arranged in a matrix form of the spring stretched in the vertical direction inside the frame woven with steel wire, laminated cushion cushioning agents such as palm rock, urethane or wool layer on the upper and lower sides and then the whole plastering It is comprised by covering.

However, in this conventional bed mattress, the springs arranged in a matrix are interconnected along the horizontal and vertical directions so that vibrations of adjacent springs are transmitted to other adjacent springs, and when the human body is moved on the mattress, they are integrally connected to each other. There is a problem that rocking occurs due to the chain action of the connected spring.

In addition, in such a conventional mattress for a bed, the spring disposed in a region that receives a relatively large load when the period of use has elapsed, the elastic force is lowered not only sag phenomenon occurs, but even if this sag phenomenon occurs, each spring is There is a problem that the maintenance is difficult because it is interconnected along the horizontal and / or longitudinal direction.

Accordingly, it is an object of the present invention to provide a bed mattress that can suppress the vibration of the spring member from being transmitted to an adjacent spring member and can facilitate the replacement of parts.

Radix grooves 24 are formed. The locking projection receiving groove 24 extends downwardly along the up and down direction from the inlet area and then bent along the circumferential direction so that the upper housing 32 and the lower housing 23 can be prevented from being separated from each other. The spring member 22 is formed to extend downward in a predetermined length so as to be movable downward along the axial direction so as to be compressed. Here, the section formed along the circumferential direction of the locking projection receiving groove 24 may be formed to be inclined a predetermined upward with respect to the insertion direction along the circumferential direction.

In the lower region of the lower housing 23, a sliding contact portion 26 having an arcuate cross section in which the central region protrudes downward is formed so as to enable pivoting with respect to the frame 11, and in the central region of the sliding contact portion 26, Through-holes 28 are formed to act as stoppers to limit the pivot range of the housing 23.

The lower side of the lower housing 23 is fixed to the base plate 13 with a support surface 54 of an arcuate cross section in which the central area is recessed downward to correspond to the sliding contact 26 so that the lower housing 23 can pivot. The support member 52 is installed to support it, and the bolt hole 56 penetrates to the center region of the support member 52 so that the fixing bolt 15 coupled to the base plate 13 can pass therethrough. It is.

Inside the lower housing 23 is arranged a pivot guide member 62 having an arcuate cross section corresponding to the shape of the sliding contact 26 and contacting the sliding contact 26 to guide the pivoting movement of the lower housing 23. The lubrication member 64 is provided between the lower housing 23 and the support member 52 to smooth the relative movement of the sliding contact portion 26 and the support member 52 and to prevent wear. Intervened. Bolt holes 63 and 65 are formed in the center regions of the pivot guide member 62 and the lubrication member 64 so that the fixing bolts 15 can be inserted therethrough.

By this configuration, the fixing bolt 15 is coupled to the male screw portion protrudes upward in each bolt hole 14 of the base plate 13. Here, the fixing bolt 15 is preferably configured to be integrally coupled to the base plate 13 by a method such as welding.

The support member 52 is coupled to each of the fixing bolts 15, and the lower housing 23 is coupled through the lubrication member 64. The pivot guide member 62 is coupled to the inside of the lower housing 23, and the nut 57 is fastened to the protruding male thread so that they are integrally fixed to the base plate 13, and to the interior of the lower housing 23. Insert and engage the spring member (22).

On the other hand, the fixing bolt 46 integrally formed in the housing coupling portion 44 of the soft member 42 is coupled to pass through the bolt hole 33 of the upper housing 32, and protrudes into the upper housing 32. The nut 47 is fastened to the male screw portion of the fixed bolt 46 so that the soft member 42 and the upper housing 32 are integrally coupled to each other.

When the locking projection 34 of the upper housing 32 is disposed to correspond to the inlet of the locking projection receiving groove 24 of the lower housing 23, when the upper housing 32 is pressed downward, the spring member 22 is pressed. The predetermined compression and the locking projection 34 is moved downward along the locking projection receiving groove (24). When the locking protrusion 34 reaches the bending area of the locking protrusion receiving groove 24 and stops, the locking protrusion 34 is rotated along the circumferential direction to complete the coupling.

On the other hand, when the period of use has elapsed, damage or breakdown of the parts or the elastic force of the spring member 22 is lowered, if the upper housing 32 is rotated relative to the lower housing 23 as opposed to when the separation is separated The parts can be replaced simply.
