Abstract

The utility model relates to an automatic quilt covering bed. When a quilt is kicked away, an electric machine is caused to drive a stay bar by a contact switch, and a transmission belt which is fixed on the stay bar is caused to draw back the quilt. After the quilt is drawn back, the contact switch causes the electrical machine to realize reverse rotation, and the stay bar retracts and draws the transmission belt to cause the quilt to return the original place.

Description

Automatic quilt covering bed

The utility model belongs to daily necessities, is a kind of for the infant or provide special care to the bed that patient uses.

Infant or some are provided special care to patient, and be poor because of self-control, in bed, after often quilt being kicked open, can oneself not build, need the head of a family or nurse to help, and the head of a family's who has so just influenced rest has increased workload for nursing.Because after night, quilt was kicked open, often be difficult in time find again, cause child or patient flu to catch a cold.

The purpose of this utility model is a kind of bed that can be built automatically after kicking open at quilt of design.And pressed at some quilt some in particular cases, can sound the alarm.

The purpose of this utility model realizes by following scheme: on general bedstead a quilt strut is set, quilt is fixed on the conveyer belt, and conveyer belt is a tape loop, slidably reciprocates on strut by lasso.This can move up and down strut along the column of the head of a bed under motor and transmission cone gear-driven.The front end of conveyer belt is by a belt-driven wheel, and the rear end is passed through by two fixed pulleys and the pulley system that movable pulley is formed.Be equipped with the upper and lower contact switch behind the bedstead on the end support.

After quilt was kicked open, the conveyer belt of quilt rear end was blocked and can not move by a fixed pulley because of lasso, so the belt of endless conveyor top draws in, spring on the movable pulley elongates, movable pulley moves down to contact with lower contact and produces a signal and give motor, make on the strut and move, spring support with on move, support contacts with the upper contact switch, give motor a signal counter-rotating, strut moves down, simultaneously, the driving-belt driving wheel rotates and makes the driving-belt return, and the pulling quilt is return also.

Below in conjunction with accompanying drawing structure of the present utility model is elaborated.

Fig. 1 is the overall structure schematic diagram of the utility model automatic cover bed.

Fig. 2 is the strut and the driving-belt drives structure schematic diagram of the utility model automatic cover bed.

Fig. 3 is the overarm support structural representation of the utility model automatic cover bed.

Fig. 4 and Fig. 5 are that the utility model automatic cover bed strut promotes and quilt restoring action schematic diagram.

Whole automatic cover bed is the bedstead (17) by as shown in Figure 1, quilt strut (2), and driving-belt (3) and drives structure are formed.The basic structure of bedstead (17) is similar substantially with common bed, but two bedstead is suitably increased, above bed board, increased quilt strut (2), it partly is to be supported on the column (1) that strut (2) is positioned at the head of a bed, can slide up and down along column (1), pulley bracket (8) is equipped with in strut (2) other end, can slide up and down along the bedstead after-poppet.Be with driving-belt (3) on the strut (2), driving-belt (3) is a tape loop, walks around driving-belt driving wheel (15) at front end, in the rear end, walks around and decides slip (6), movable pulley (7) and fixed pulley (5).Driving-belt (3) is to be enclosed within on the strut (2) by lasso (18), and lasso (18) is fixed with belt and quilt.Lasso (18) can be slided along strut (2) by driving-belt (3) traction.Strut (2) partly also has support (12) at the head of a bed, support (12) also is sleeved on the column (1), and prop up strut (2), a side band tooth of column (1), and engagement in the small conical gear (11), large conical gear (16) and bevel pinion (11) external toothing, large conical gear is driven by motor (14), driving-belt driving wheel (15) is also driven by motor (14), and motor (14) is to be fixed on the electric machine support (13).Motor rotates, and drives driving-belt driving wheel (15), and large conical gear (16), makes driving-belt (3) cycle rotation, drives small conical gear simultaneously and rotates, and small conical gear (11) moves up and down along column (1), drives strut (2) simultaneously and moves up and down.

Can see the process of whole automatic cover from Fig. 4, Fig. 5.

When quilt is kicked open, lasso (18) is moved backward, spur driving-belt (3) simultaneously, driving-belt (3) is a tape loop, the top moves right, the below is to reach, by two fixed pulleys (5), (6), the pulling movable pulley (7), because of lasso (18) by fixed pulley (5) block can not after move, driving-belt (3) the first half is tightened up like this, pulling movable pulley (7) moves down, spring (19) draws back, and movable pulley (7) moves down into to a certain degree and contacts with lower contact switch (10), starter motor (14), make large conical gear (16) drive small conical gear (11) and go up rotation at column (1), small conical gear (11) and toothed column (1) are interior engagements, move so small conical gear drives on the support (12), make on the strut (2) and move, whole quilt is mentioned, reach position shown in Figure 5, because of driving-belt driving wheel (15) is a unidirectional drive, so driving wheel this moment (15) rotates.On strut (2), move, drive on the pulley bracket (8) and move, support (8) is contacted with upper contact switch (9), motor (14) counter-rotating, strut (2) is moved down, and driving-belt driving wheel (15) rotates simultaneously, and quilt is retracted original position, and the action that moves down of strut (2) cooperates, and quilt is built automatically.The effect of spring (19) can be played quilt, otherwise that child understands is fidgety, and simultaneously, after quilt was raised, the spring of stretching (19) helped the quilt return.

Be touched (10) if quilt is kicked open the lower contact switch, and after the motor action, strut (2) draws motionless quilt, at this moment may have been pushed down by health by quilt, and circuit will provide corresponding sound or visual alarm, reminds the head of a family or nurse to handle.

(4) among Fig. 1 are backplates, prevent to touch unintentionally driving-belt.
