Abstract

The utility model discloses an adjustable chair for use on the bed which is composed of a chair base and a backrest frame. A wavy block is designed on the base and the backrest frame is provided with a movable support, so the slope angle of the upper body of the human body can be adjusted, and the slope angle can be 40 DEG, 47 DEG, 54 DEG, 60 DEG, 66 DEG, and 72 DEG which is suitable for various needs. A backrest cushion made of the textile is comfortable. The entire utensil adopts a movable structure. The used material is less, the process is simple, and the cost is lower.

Description

Adjustable chair for use on the bed

The utility model relates to arm-chair on a kind of adjustable angle formula bed, can be widely used in hospital, family.

In daily life, hospital's sick bed at adjustable angle of inclination is arranged at present, the barbed chair on automobile, the aircraft, home-use adjustable chaise longue etc., popular to people deeply.But we observe, and they all are to be supported on the ground, or are fixed in ground, and are not removable, more can not put in bed, can not satisfy the patient or the uncomfortable person's of clinotherapy, rest demand.

The purpose of this utility model is to avoid the weak point in the above-mentioned existing product, provides a kind of inclination angle easy to adjust, moves, easily folding, and the simple bed of processing and manufacturing is gone up arm-chair.

The purpose of this utility model can reach by following measure: arm-chair has been discarded the seat surface of common chair stool on the bed, and by bed surface, replacements such as bed clothes, put a support in the backrest back, it is base of the present utility model, base ［ 1 ］ can be put in bed, be connected with a back rest ［ 3 ］ above, make with metal, be with the back cushion ［ 4 ］ that yarn fabric is made on the back rest, on back rest, be connected with a travel(l)ing rest ［ 5 ］, it can prop up a certain the blocking of the wavy retaining ［ 2 ］ on base, just can regulate the angle of inclination of backrest with different retainings, lies by demand to adapt to the various of people.

The drawing of accompanying drawing is described as follows: go up the arm-chair structural representation for the inclination angle is adjustable bed among the figure.The 1--base, the wavy retaining of 2--, the 3--back rest, the 4--back cushion, the 5--travel(l)ing rest, α--be the angle between back rest and the base (acute angle).

Below in conjunction with accompanying drawing embodiment is done progressive a detailed description in detail: will to be narrower than general bed surface wide for the base of arm-chair ［ 1 ］ width on the bed, can be designed to wide about 40CM, the about 50CM of length; Two limits of base respectively are welded with wavy retaining ［ 2 ］, make with reinforcing bar, can establish 6 retainings, keeping off wide 5.4CM, is 5.4CM also between retaining, keeps off high 5CM, first retaining starting point and base, back rest near the end prop up intersection point apart from being about 19CM, and the wavy retaining in both sides wants symmetry to weld.The both ends of base ［ 1 ］ use a metal shaft ［ 6 ］ to be connected respectively with the both ends of back rest ［ 3 ］, be out of shape to prevent arm-chair, but two junctions can be relatively rotated, and open in use, and the time spent does not close, so that carry.The material selection steel pipe, diameter of steel tube is greater than 1CM.The length and width of back rest ［ 3 ］ is designed to be about 55CM than the wide diameter of steel tube of base, and wide about 43CM is so that carry time folding on the same plane of base.In use, the back rest both sides put yarn fabric, and for example canvas, chemical fabric etc. are born the human body upper body weight, to adapt to the needs that human body leans on, make to lean against and feel comfortable on the arm-chair, and back cushion ［ 4 ］ will design widelyer up and down.At distance base, back rest tie point 30CM place, one travel(l)ing rest ［ 5 ］ is installed, become U type structure, be connected on the back rest, its free position can be inserted in each wavy retaining with the need, can regulate the inclination angle of backrest and bed surface, angle is about 40 degree, 47 degree, 54 degree, 60 degree, 66 degree, 72 degree, appoints and selects one.Angle α is too big, supports and owes firmly and not too suitable body shape, and too little then travel(l)ing rest tie point is stressed too big, also inapplicable.The about 30CM of the length of support, width goes out a diameter of steel tube than back rest is wide again, and about 46CM also is to be convenient to harvesting in order rolling over together or to carry.

Solids such as all supports, finished surface all need be covered with paint, lacquer, colour wash, etc., and as the plating Lip river, paint, be coated with organic coating etc., makes it attractive in appearance, antirust, durable, and with the bedding style that is consistent.

The utility model has following advantage compared to existing technology: can place on the bed, comfortable, light, durable, it is simple and easy to do to regulate the inclination angle, not collapsible harvesting of time spent, and floor space is little, is the standing apparatus of hospital, family, and higher popularization practicality is arranged. Because simple for production, materials are few, and are therefore cheap.
