Description

The structure of Chair with curved arms

＜one〉technical field:

The utility model provides a kind of structure of Chair with curved arms, refers to a kind of Chair with curved arms that can significantly improve load-bearing power and support strength and have the simplification process benefit especially, belongs to study, office chair tool.

＜two〉background technology:

In view of having the support force deficiency, traditional Chair with curved arms cause board to tilt and board can't the whole shortcoming of anteroposterior position transposition, the applicant has once applied for name being called " structural improvement of Chair with curved arms " novel patent application on April 18th, 2000, and (the Taiwan application number is 089206285 in Taiwan, it number is 457896 that platform is accused), see Fig. 1, shown in Figure 2, it mainly ties up on the chair tool support frame 104 and sets firmly outer tube 1, the interior pipe 2 that will be placed through again in the outer tube 1 is fixedly arranged on board 20 bottoms, with improve the support force of board 20 and in utilizing pipe 2 in outer tube 1 slippage and reach purpose and the effect that board 20 displacements are adjusted, but this structural design has the following improvement part that needs:

As shown in Figure 1, because this board 20 necessarily requires to lift smoothly and opens, be to reserve a gap (as shown in Figure 2) with outer tube 1 end face and skeleton 4 root edges, board 20 can lift like this, the support force of this board 20 is stronger with the side that forward and backward lug 41 is provided with, another opposite side then a little less than; For pipe 2 in making is fixedly arranged between two lugs 41, still need in the interior pipe 2 place a length surpass the screw rod 3 of interior pipe 2 ', utilize again nut 31 ', 32 ' spiral shell is solid, directly causes the inconvenience of assembling process;

The purpose of this utility model is to provide a kind of structure of new-type Chair with curved arms, mainly has the advantage and the effect that significantly improve load-bearing power and support strength and simplify manufacture process.

＜three〉summary of the invention:

A kind of structure of Chair with curved arms comprises a side and sets firmly the chair tool of support frame and an end and be arranged at board on the support frame; Wherein, set firmly an outer tube on the support frame, place a length in the outer tube and manage within the outer pipe range; The board bottom is installed with the shaped as frame skeleton, skeleton sets firmly two lugs near a side of support frame, between two lugs in suitable the appearance pipe insert therebetween, a perforation is offered at two lug lamellar body centers respectively, and wherein perforation one side and moulding one arc-shaped slot of a lug; It is characterized in that: interior Guan Yiduan end face center is convexly equipped with an axostylus axostyle, and axostylus axostyle one side and off-centre are convexly equipped with a latch, and other end face then sets firmly an inner bolt hole seat; Set firmly one the reinforcement bracing frame between the shaped as frame skeleton of board in addition, this road reinforcement bracing frame also extends a linking rib and connects a wherein lug, and shaped as frame skeleton one side then has together outwardly tube side to extending and at the reinforced ribs that is bent to form the inclination support chip near outer tunnel end; Use setting, interior pipe is placed through in the outer tube, one end axostylus axostyle and latch are inserted and to be pulled in the perforation and arc-shaped slot of a lug wherein, in the in addition then perforation and admittedly of corresponding another lug of screw seat of end of pipe for a bolt spiral shell, the support chip of board bottom then can support and outer tube wall supports to form, and strengthens the opposite end support force of board tool lug.

Wherein, interior Guan Yiduan axostylus axostyle can make it clip on lug in the slightly punching press of axostylus axostyle front end after inserting the lug perforation.

Wherein, the support frame inside of Chair with curved arms can set firmly several and be connected to vertical auxiliary pole on the skeleton.

Wherein, on the inner tube face with the board bottom surface before lug the eccentric latch and the arc-shaped slot of pair of opposing can be set.
