The specific embodiment
Provide the specific embodiment of the adjustable sofa of a kind of handrail of the utility model below in conjunction with accompanying drawing, still, enforcement of the present utility model is not limited to following embodiment.
Referring to accompanying drawing 1,2, the adjustable sofa of a kind of handrail contains underframe 1, sofa seat surface 2, right handrail 3, left handrail 5 and backrest 4.Described underframe 1 comprises underframe sill 101, underframe entablature 102, feet 103 and support column 104, can adopt timber or rigidity aluminium alloy pipe equal strength better, the material manufacturing of lighter weight.Be fixedly connected with two support columns 104 between described underframe sill 101 and the underframe entablature 102, primary structure for underframe 1, described underframe sill 101 is fixedly connected with four feets 103, form sofa ground structure (in the enforcement, a roller can respectively be set in the outer end of described four feets 103, the roller that adopts should be provided with brake structure, is convenient to movement, braking and the carrying of sofa).The outer end, both sides of described underframe sill 101 and underframe entablature 102 is the syndeton end.Affixed sofa seat surface 2 on described underframe entablature 102; In the rear end of described sofa seat surface backrest 4 is set.In the enforcement, sofa seat surface 2 and backrest 4 separately can be made, then be linked together.Also sofa seat surface 2 and backrest 4 can be made an integrative-structure, then attach it on the underframe entablature 102.Such firmness may be better.
Described sofa seat surface 2 can be made seat surfaces single or double or three people.Consider from the angle of result of use or area occupied, adopt double wide seat surface effect meeting better.
Right handrail 3 and left handrail 5 are set at the two ends of described sofa seat surface 2, connecting plate 7 at affixed two sheet metal structurals in the back of described right handrail 3, an affixed support bar 6 again on connecting plate 7, the lower end of described support bar 6 is hinged with an end of described underframe entablature 102 by the second rotational pin 12, the formation revolute pair connects, the upper end of described support bar 7 is hinged with the upper end of slip positioning pipe 6 by the first rotational pin 11, the formation revolute pair connects, length direction in described slip positioning pipe 8 outsides is provided with row's circular hole, the lower end of described slip positioning pipe 8 is actively socketed in the supporting and location pipe 9, outer upper at supporting and location pipe 9 is provided with a locating hole boss, be connected with dog screw 10 in described locating hole boss, described slip positioning pipe 8 passes through described circular hole and described locating hole dog screw 10 alternative interlockings with supporting and location pipe 9; The lower end of described supporting and location pipe 8 is hinged with an end of underframe sill 101 by the 3rd rotational pin 13, forms revolute pair and connects; That is, the adjustment of described right handrail 3 height and angle is finished by three revolute pair syndetons.
Above-mentioned slip positioning pipe 8, supporting and location pipe 9 employing pipe thicknesses equal the structural member greater than 5mm.Slip positioning pipe 8 and 9 sockets of supporting and location pipe, the gap of socket should be less than or equal to 3mm, with avoid fixing rear right handrail 3 can generation rocking by a relatively large margin, make the people produce sense of discomfort.The aperture design of circular hole in a row is 10mm on locating hole on the described locating hole boss and the described slip positioning pipe 8.In the enforcement, can be 10mm with the aperture design of described locating hole, with the aperture design of described circular hole in a row for equaling greater than 10mm; Inwall place at locating hole arranges screw thread, outer wall place at described dog screw 10 arranges screw thread, described dog screw 10 is connected by helicitic texture with described locating hole, and described dog screw 10 can embed in the hole in the circular hole in a row by described locating hole, plays spacing effect.
The setting of described left handrail 5 and syndeton can be carried out with reference to setting and the syndeton of described right handrail 3.Should note in the enforcement, to the level latch-up structure be set at described the second rotational pin 12, to guarantee when the right handrail 3 of sofa and left handrail 5 are horizontal, carrying out the locking of horizontal structure, guarantee that sofa of the present utility model can be used as simple and easy single bed use.
The adjustable sofa of a kind of handrail of the utility model is when needs are regulated, user's certain distance of dog screw 10 can being back-outed first makes it to break away from circular hole, slip positioning pipe 8 is lifted restrictions also can be in the 9 interior any movements of supporting and location pipe, when connecting by revolute pair when right handrail 3 or left handrail 5 be adjusted to desired location, with the link position of dog screw 10 by locating hole and circular hole locking slip positioning pipe 8 and supporting and location pipe 9, screwed in place screw 10 gets final product again.
When the right handrail 3 of sofa and left handrail 5 were in plumbness, the utility model can satisfy the instructions for use of general sitting posture.
The level latch-up structure that arranges on by the second rotational pin 12 as the right handrail 3 of sofa, left handrail 5() when being horizontal, the utility model can be used as easy single bed and uses.
When right handrail 3, the left handrail 5 of sofa is in other when arbitrarily angled, the instructions for use of posture that the utility model can satisfy that the user lies on one's side etc.
In addition, the user can be adjusted to right handrail 3 of the present utility model and left handrail 5 voluntarily the individual and feel that the most comfortable angle uses, and whole process is very simple and convenient.
