The angle can be adjusted constantly with convenient utilization as well as even and proper bearing. Besides, the utility model is free from discomfort and durable. Consumers can adjust the inclined angle of bed backrest in a larger scope according to private demands (such as watching TV, reading, rest and etc). The utility model has the advantages of simple structure, comfortable utilization, convenient adjustment and complete shape etc, assorted with the living environment well, and has a wide market expectation.

Description

The novel backrest bed of tilt adjustable formula

Technical field

The utility model relates to a kind of backrest bed, more precisely a kind of backrest bed of tilt adjustable.

Background technology

Though the backrest of present widely used bed has many distortion and decoration, citation form still is plane inclined uprightly or a little, and its angle can not change, if horizontally-inclined reads in bed or writes and can make the people feel very uncomfortable, and fatigue easily.To this, Chinese patent CN2044444U just discloses a kind of Back for reading, it mainly is made up of connecting axle, gripper shoe, handle, zigzag step etc., adjusting angle as required, but its structure is comparatively complicated, and backrest is being propped up time-out, and the backrest lower edge can produce a projection, withstand on people's back, still feel under the weather.Chinese patent CN92234904.5 disclosed " bed-rest of tilt adjustable " and for example, the structure of this backrest bed as shown in Figure 1, comprise fixedly backrest 6 and movable back 2, fixedly the backrest upper end is connected with an end of connecting rod 4 by hinge 5, the other end of connecting rod 4 connects movable back 2 by hinge 3, though advantage simple in structure, that the inclination angle can be regulated continuously that this backrest bed has, but movable back 2 will inevitably travel forward when regulating, thereby take effective usable floor area of bed, and human body must leave bed-rest when regulating, and brings inconvenience to the user.Chinese patent CN02261345.5 disclosed " bed use motorized adjustment back-rest means for chair " for another example, it is installed with worm type of reduction gearing in bed body base of frame, motor output shaft links to each other with reducer input shaft, the reducer output shaft connecting crank, the crank connecting rod that is rotationally connected, connecting rod backrest one end that is connected through the hinge, a backrest lower end body framework that is connected through the hinge, backrest, crank and connecting rod constitute the crank rocker reciprocating mechanism, promote bed-rest and do the angle variation with respect to the bed body, though this adjusting device has been expanded the function of use of head of a bed part, but its structure is too complicated, need a series of driving, drive disk assembly participates in motion, and operation is very much loaded down with trivial details, can not extensively popularize in average family.

The utility model content

At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of tilt adjustable formula simple in structure, that use is comfortable, easy to adjust, profile is complete novel backrest bed.

For achieving the above object, the technical solution adopted in the utility model is:

The novel backrest bed of a kind of tilt adjustable formula, comprise a body framework and movable bed-rest, the lower end of bed-rest inner support is rotationally connected with bed body framework at head of a bed place by adjustable self-positioning hinge, this hinge is provided with a fixed arm and a cursor, fixed arm fixes with bed body framework, and lever arm and bed-rest inner support fix.

Offer connecting hole on the fixed arm of described hinge, bed body framework is provided with corresponding with it contiguous block, also offers connecting hole on the contiguous block, interconnects by screw between the two.

Described bed-rest inner support is the irony support, and the cursor of hinge is welded to connect with it.

Described backrest bed is double backrest bed, and bed body framework is provided with two separate bed-rests.

Hinge by a plurality of coaxial settings between described bed-rest and the bed body framework interconnects.

Hinge by three coaxial settings between described bed-rest and the bed body framework interconnects.

Be coated with the Bed cushion bag on the described bed-rest, this Bed cushion bag is coated to the back from pile warp top, bed-rest front always, and ties up on bed-rest with the frenulum mode in both sides.

Be coated with removable lining on the outer surface of the support of described bed body framework and bed-rest.

Described bed body inside of frame is provided with multiple tracks and supports girder longitudinally, and suitable at interval distance is provided with the cross-brace plate that parallels equably between the girder.

Described horizontal gripper shoe is the arc that upwards arches upward.

Interconnect by adjustable self-positioning hinge between bed-rest of the present utility model and the bed body framework, its angle can be regulated continuously, not only easy to use but also stressing conditions is evenly reasonable, there is not sense of discomfort, heavily fortified point very is durable for a long time, the consumer can (as see TV according to self-demand, reading, rests etc.) angle of inclination to bed-rest in is in a big way regulated, need not extra operation, as long as lean against on the backrest and promptly be adjustable to satisfied level of comfort to after-applied certain pressure, and the location is reliable, profile is complete, can be harmonious with living environment well.
