Description

Electric chairbed

The utility model relates to a kind of bed that can make the people sit up automatically and play and couch, and is fit to family and hospital and uses.

Existing various beds for domestic use mainly is made up of bed head frame, tailstock frame, bed board etc., when becoming sitting posture by couching, to the residual person of the old and the weak Epileptic difficulty relatively often.Though medical Epileptic bed function is different, complex structure is difficult to promote the use of.As DRP DE3103922 " lifting apparatus of hospital bed first half ", " hospital (changes the gradient of a foot part with regulating bed to U.S. Pat 4183109 with motor, change people's sitting posture) " all be the structure more complicated, the manufacturing cost height, no

Promote, more be difficult to enter family and use.

The purpose of this utility model be to provide a kind of stressed reasonable, simple in structure, function is moderate, easy to operate, cheap and electronic of safety and comfort mounts the throne.Be fit to the residual person of the old and the weak Epileptic and transfer sitting posture and often book or newspaper reading and people's use of televiewing in bed automatically to by sleeping position in bed.

The utility model is to rotate De Ku back of the body bed board (2), rotating seat bed board (3), rotating shank bed board (4), motor (5), belt pulley (6), leading screw (7), nut (8), pull bar (9), rotating support (10), block (11), lever (12) and limit switch (13), buffering usefulness by dismountable bedstead (1), Ke

The property pad (14), sheet anti-curling device (15) form.

Fig. 1 is just of the present utility model

View.

Fig. 2 is motor, belt pulley, leading screw, nut portion structure chart (seeing Fig. 1: analyse and observe along A-A).

Fig. 3 is welded support figure.

Fig. 4 is the rod foundry goods support figure in tape spool hole.

Shown in Figure 5 is block (11).

Down Reaching embodiment in conjunction with the accompanying drawings describes in further detail.

Action of the present utility model is that push button is pressed in realization (seeing Fig. 1, Fig. 2) like this, the power of motor (5) makes silk shoulder (7) after belt pulley (6) transmission is slowed down and rotates, drive rotating support (10) through nut (8), pull bar (9) again and rotate, ask Ku back of the body bed board (2) to rise and taken office

Angle makes the people become sitting posture by couching.When needs bend one's legs action, rotary block (11) in advance, make block (11) be in the position that can promote lever (12), like this when support (10) Tuo Qi Ku back of the body bed board (2) inserts to 30 °～40 °, the block (11) that links together with nut drives lever (12) rotation simultaneously, support the seat part (3) of bed board, and shank bed board (4) is rotated naturally.Leading screw bears pulling force in the course of the work, and is flat with assurance work

Support shown in Figure 3 (10) be with the garden steel be welded into four

The body framing component also can be the rod foundry goods that adopts the tape spool hole as shown in Figure 4.

Block shown in Figure 5 (11) can rotate around self axis, is in operating position or off-position with decision.Block (11) promotes lever (12) when the operating position, realize the rotation of seat bed board (3), if need not bend one's legs the time, only needs make it be in off-position in advance with 90 ° of block (11) transpositions.

For guaranteeing safe handling, the extreme position that the utility model rotates with limit switch (13) restriction bed board (2).When Wu Dianyuan, can shake by one handle, make bed can carry out manual control with the hand rotating pulley or at axle head.

The utility model is equipped with in the bottom of bed board (2), (3), (4)

The property element (as The property plastics Rubber cushion or Spring) buffer unit of Gou Chenging (14) is flat when guaranteeing that bed board is set level

, comfortable.When staff is put into accidentally, the also unlikely staff that crushes.

Sheet is unlikely to be rolled in order to make, and is fixed with sheet anti-curling device (as wood clamp, plastic clip or velcro) (15) in the both sides of bed board pivotable parts.

When the utility model was used for double bed, counting of corresponding increase bed board transposition part (2), (3) was two, becomes two-side supporting (seeing shown in Figure 4) by intermediate support.Remainder and single bed are identical, so both can be used for the wooden structure bed, also can be used for single, double people's bed of steel construction bed or steel wood mixed structure.

Claims (5)

1. one by dismountable bedstead (1), Ke rotates De Ku back of the body bed board (2), rotating seat bed board (3), rotating shank bed board (4), motor (5), belt pulley (6), leading screw (7), nut (8), pull bar (9), the bed that lever (12) is formed, it is characterized in that having rotating support (10), block (11), limit switch (13), buffer unit (14), sheet anti-curling device (15), press the rotation of push button operated motor and after pulley decelerates, reach feed screw nut drive pull bar, rotating support (10), block (11), make the bed the corresponding rotation of pivotable parts, allow the people with Sit and crouch.

2. sell bed according to claim 1, it is characterized in that the plate extreme position of rotating with limit switch (13) control bed board (2).
