CN2140660Y - Head of bed with self-adjustable inclination - Google Patents

Abstract

The utility model discloses the head of a bed with self-adjustable inclination, which is characterized in that the head of a bed comprises support frames whose upper ends are mutually connected together of the head of a bed and an inclined backrest; the lower end of the support frame of the head of a bed is arranged in the sliding chute of the foot of the bed on one end of the head of a bed; a pulley and a driving rope are used for adjusting. When the support frame of the head of a bed slides downwards, the included angle between the inclined backrest and the support frame of the head of a bed is enlarged; on the contrary, when the support frame of the head of a bed slides upwards, the included angle between the inclined backrest and the support frame of the head of a bed is diminished; the inclined backrest and the bedstead can be overlapped together. The user who lies on a bed can automatically operate the adjustment. The utility model has the advantages of convenient operation, simple structure and low cost.

Description

Head of bed with self-adjustable inclination

The utility model belongs to a kind of and uses the headstock, is meant the head of a bed of regulating the inclination angle with transmission device especially.

In the prior art, though the head of a bed of medical adjustable inclination is arranged, the medical adjustable head of a bed of this class is complex structure often, and cost is higher, and needs other people to regulate operation, therefore can't promote as a kind of family expenses head of a bed.

The purpose of this utility model provides a kind of simple and reasonable, can be regulated the head of a bed at inclination angle by end user oneself.

Embodiment of the present utility model is that the head of a bed is designed to the head of a bed support that is interconnected by the upper end and leans to constitute.The roller that can move is equipped with in the lower end that leans on bedstead, the upper and lower side of head of a bed support is respectively installed a top sheave and lower sheave, one worm and wormwheel speed change gear is installed at the back side that leans to, coaxial installation one worm gear coupled wheel on this worm gear, the worm screw crank is housed on this worm screw, be fixedly connected on the worm gear coupled wheel and walk around worm gear coupled wheel, top sheave and lower sheave successively with an end of a transmission rope, the other end with transmission rope is fixed on the bedstead then.

Accompanying drawing is the utility model example structure schematic diagram.

The drawing explanation:

The 1-cabinet base, the 2-lower sheave, 3-head of a bed support, the 4-transmission rope, the 5-top sheave, 6-leans to, 7-worm gear coupled wheel, 8-worm and wormwheel speed change gear, 9-worm screw crank, 10-roller, 11-bedstead.

The utility model has the advantages that: the end user can regulate voluntarily to the angle of inclination of the head of a bed, and is freely easy to use, the head of a bed of this self-adjustable inclination, and simple and reasonable, cost is cheap, is a kind of novel furniture of promoting future that has.

Embodiment:

Accompanying drawing is the structural representation of the utility model embodiment.This head of a bed is the head of a bed support 3 that is interconnected by the upper end and leans to 6 and constitute, the lower end of head of a bed support 3 is installed in the chute of the head of a bed one end cabinet base 1, lean to 6 lower end the roller 10 that can move on bedstead 11 is housed, the upper and lower side of head of a bed support 3 is respectively installed a top sheave 5 and lower sheave 2, one worm and wormwheel speed change gear 8 is installed at the back side that leans to 6, coaxial installation one worm gear coupled wheel 7 on this worm gear, worm screw crank 9 is housed on this worm screw, be fixedly connected on the worm gear coupled wheel 7 and walk around worm gear coupled wheel 7 successively with an end of a transmission rope 4, top sheave 5 and lower sheave 2, the other end with transmission rope is fixed on the bedstead 11 then.When shaking worm screw crank 9, the end user does the clockwise direction rotation, transmission rope 4 is on worm gear interlock pulley 7, make effective use contraction in length of transmission rope 4, thereby upwards 3 liftings of head of a bed support, and make lean to 6 and the angle of head of a bed support 3 diminish, rotation can reach always and lean to 6 and head of a bed support 3 is overlapping substantially and perpendicular to the position of bedstead in the direction of the clock.When the end user shook worm screw crank 9 counter clockwise, then the transmission rope 4 on the worm gear coupled wheel 7 was loosened, and head of a bed support 3 is because of gravity glides, strengthened lean to 6 and head of a bed support 3 between angle.

Claims (1)

1, a kind of head of a bed that can regulate the inclination angle automatically, it is characterized in that: this head of a bed is the head of a bed support 3 that is interconnected by the upper end and leans to 6 and constitute, the lower end of head of a bed support 3 is installed in the chute of the head of a bed one end cabinet base 1, lean to 6 lower end the roller 10 that can move on bedstead 11 is housed, the upper and lower side of head of a bed support 3 is respectively installed a top sheave 5 and lower sheave 2, one worm and wormwheel speed change gear 8 is installed at the back side that leans to 6, coaxial installation one worm gear coupled wheel 7 on this worm gear, worm screw crank 9 is housed on this worm screw, be fixedly connected on the worm gear coupled wheel 7 and walk around worm gear coupled wheel 7 successively with an end of a transmission rope 4, top sheave 5 and lower sheave 2, the other end with transmission rope is fixed on the bedstead 11 then.
