Abstract

The invention discloses a baby chair which comprises an arch backrest, the two ends of which are respectively connected with a retaining arm by joints. The retaining arms can be folded inwards around the joints. The lower part of the connecting end of the retaining arm is connected with a sway brace by joints; the sway brace can support the underside of a desktop and be folded inwards around the joints. The baby chair with reduced size is obtained after folding twice. The baby chair has the advantages of being foldable and firmly positioned, thereby being convenient to transport and store, besides, a support frame composed of special pipes is used, thereby being more comfortable and more applicable to the physiological characteristics of babies.

Description

Baby table chair

Technical field

The present invention relates to baby table chair, be specifically related to a kind of passing through and fold, thus the baby table chair of realization reduced volume.

Background technology

Known baby table chair as shown in Figure 1, comprise backrest 1` for baby's seating, with two the arm shape part 2`s of described chair partial fixing on desk, by described arm shape part on the table clamping limb 3` and the support arm 4` under the desktop be stuck on the desk, the shortcoming of this desktop chair is: clamping limb 3` on the desktop and the support arm 4` under the desktop do not have folder function; There is not stopping means on the horizontal level, locate firm inadequately, support arm 4` under clamping limb 3` and the desktop is fixedly connected on the backrest, can not fold, when transporting and depositing, take bigger space, in addition, for active and realize poor baby, the danger that also exists desktop chair to fall; And because the chair of chair part leans on and the handrail sustained height, the lines of whole chair part are single stiff, are not suitable for the tender infant sitting of health and lean on;

Summary of the invention

The objective of the invention is to, overcome deficiency of the prior art, provide a kind of backrest and wall shape part to fold, collapsible between clamping limb on the desktop and the support arm under the desktop, be provided with collapsible and dismountable support arm in the support arm inboard, be fit to the desktop chair of infant's physilogical characteristics.

Purpose of the present invention is achieved by following technical proposals: construct a kind of baby table chair, comprise arcuate backrest, the two ends of described arcuate backrest respectively are connected with a clamping limb by the joint, and described clamping limb can be inwardly folding around the joint; Bottom at the clamping limb link is connected with a support arm that can be supported on the table bottom surface by the joint, and described support arm can be inwardly folding around the joint, but by twice folding baby table chair that obtains a reduced volume.

Described folding clamp arm comprises upper arm and the underarm that is articulated by an articulation mechanism, described upper arm upper end is by the screw rod with flat head that is threaded, described underarm lower end has the deep-slotted chip breaker that cooperates described support arm, is provided with some trip bolts on the sidewall of described deep-slotted chip breaker.

Described articulation mechanism comprises a button, upper arm lower end, a clip, a spring, underarm upper end from outside to inside successively, described button bilateral symmetry respectively is provided with a flexible strip, this flexible strip end has outwards outstanding hook portion, described upper arm lower end has the through hole that allows described flexible strip to pass through and engage, and inboard, upper arm lower end has the groove of ccontaining clip; Described clip is the circular clip with breach, and the clip center has through hole, and described underarm upper end has the groove that cooperates described clip.

Clamping limb on the described desktop and the support arm under the desktop articulate by an articulation structure.

Described articulation mechanism comprises a button from outside to inside successively, the support arm upper end, one fixes sheet, one clip, one spring, the clamping limb lower end, described button bilateral symmetry respectively is provided with a flexible strip, this flexible strip end has outwards outstanding hook portion, described support arm upper end has the through hole that allows described flexible strip to pass through, described fixing sheet has the through hole and that allows described flexible strip to pass through and is installed in shank in the support arm, described clip on circumference, have lug within it side have the circular clip of annular groove, the clip center has through hole, described spring is contained in the annular groove of clip inboard, and described clamping limb lower end has the groove that cooperates described clip.

Described clamping limb comprises the first half and the latter half that connects by screw, the first half and the latter half form the space of ccontaining backrest connector at the inner end of clamping limb, and described backrest forms articulation structure by the clamping limb inner end on a connection piece and the described desktop.

Described articulation structure is realized in such a way: have on described backrest connector by the formed fin of twice arcuate socket, on this fin, be provided with a hemispherical projections, correspondingly, have at least two circular holes that cooperate described hemispherical projections in described clamping limb the first half.

Described articulation structure is provided with dust plug, and described dust plug is one to have the plunger of decorative pattern face, and its both sides are provided with in order to the back-off structure that fixes, and correspondingly, is provided with the through hole that fastens for described back-off structure in the first half of clamping limb.

The present invention has following advantage: be connected by the articulation structure that can fold between backrest and the clamping limb; Also be connected between clamping limb and the support arm, thereby make that the volume of the baby table chair after folding is littler, conveniently transport and deposit, also be provided with articulation structure between clamping limb on the desktop and the support arm under the desktop by the articulation structure that can fold; Also be provided with collapsible and dismountable support arm in the support arm inboard, whole baby table chair has been realized good folder function, has increased collapsible and dismountable support arm, has increased the fastness of location.
