Description

A kind of brace

The utility model relates to a kind of furniture brace, especially a kind of brace that is used for the office chair handrail.

At present combining between the main body of general office chair and the handrail is to be fixed on office chair main body side in advance by a stator, by screwing togather of screw handrail is fixed on the office chair side again, known stator structure such as Fig. 4 and shown in Figure 5, comprise that mainly one is the stator 60 of L type, all be provided with a pair of pivot hole 611,631 on the faying face 61,63 of this stator 60, be provided with a pair of sleeve piece 62 in addition, these sleeve piece 62 adapter rings are provided with a retaining edge 621, and screw togather for screw at the sleeve piece 62 middle screws 623 that are provided with.

During assembling, utilize riveted way 62 rivetings of sleeve piece to be gone in the pivot hole 611 of stator 60 faying faces 61 (as shown in Figure 5) earlier, and make sleeve piece 62 1 ends form a flange 622, and the flange 622 that utilize to form blocks faying face 61 with as the strength of fixing, cooperate screw that handrail is fixed on the stator 60 at last again, after finishing assembling, flange 622 and faying face 61 combines strength as main fixed strength during by riveted, so these flange 622 suffered strength also are maximum, and the load major part that handrail bore also all is applied on the flange 622 of this sleeve piece 62, when this flange 622 through long-term stressed after, because of it does not have fixed strength, so make sleeve piece 62 produce rotation quite easily, and then have influence on the steadiness and the concreteness of handrail, even handrail situation about also can rock.

Shown in annex 1, a kind of " armrests is constructed with conjunction " disclosed in the Taiwan number of patent application 86207602, it is to utilize the volution external diameter to be with a sleeve, form to pivot between the two or fixing, prevents the purpose of rotating and reach, but, this technique known does not break through on assembling and manufacturing cost, and all structure is many and complicated regardless of structurally reaching fit on for it, and relative manufacturing cost just increases many, therefore, this technology still can't reach and solve above-mentioned shortcoming simultaneously.

The purpose of this utility model is that a kind of above-mentioned defective that overcomes will be provided, and can prevent from effectively that handrail from producing to rock or unsettled brace.

The purpose of this utility model is achieved in that a kind of brace comprises: a firm joint device, this device are provided with first brace and second brace, one-body molded formation engaging body on first brace wherein, also one-body molded formation rivet clasp body on second brace.

The utility model has the advantages that:

1, the brace that the utility model proposes, be to utilize integrated firm joint device as the integrated structure between handrail and the seat, the engaging body of one-body molded setting can increase many fixed strength on first brace of described firm joint device, mean forced because of this engaging body, even and when making handrail bear load, still can be completely fixed on the seat, difficult generation is rocked or unsettled situation.In addition, form in integrated mode between firm joint device and the engaging body, can prevent from effectively to produce rotation between the two, so the utility model has overcome the problem that exists in the known technology fully.

2, the brace that the utility model proposes, wherein set apical margin auxiliary sleeve zoarium and the location between the handrail on the engaging body make between engaging body and the handrail except the locking of screw, also have apical margin that the combined hole of handrail is produced dual location.

3, the brace that the utility model proposes, the location between auxiliary rivet clasp body of set engaging piece and the seat on the rivet clasp body wherein, make between rivet clasp body and the seat except the affixed location of punch riveting, also have engaging piece that seat is produced packing interaction and has dual positioning function.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the stereogram according to a kind of brace that the utility model proposes;

Fig. 2 is the cutaway view of A-A section among Fig. 1;

Fig. 3 is the cutaway view of B-B section among Fig. 1;

Fig. 4 is the perspective exploded view of known technology;

Fig. 5 is the cutaway view of known technology.

Below in conjunction with accompanying drawing and most preferred embodiment thereof the concrete structure that the utility model proposes is further described.

As shown in Figure 1, the brace that the utility model proposes includes: one is the firm joint device 100 of L type, this firm joint device 100 is made up of first brace 10 and second brace 20, wherein first brace 10 is fixed on the handrail 30 of seat one side, these first brace, 10 epireliefs set out integrated engaging body 11, wherein engaging body 11 is provided with an apical margin 12 with the wall that links to each other that first brace 10 is joined along the wall edge, the protrusion ora terminalis formation one of this engaging body 11 has the guiding position 13 of lead angle, and engaging body 11 inside are equipped with a screw 14; Second brace 20 is on the seat affixed, and the outer side surface of this second brace 20 convexes with integrated rivet clasp body 21, and this rivet clasp body 21 is provided with an engaging piece 22 with the wall that links to each other that second brace 20 is joined along the wall edge.

The assembling mode of described firm joint device 100 and position are please respectively referring to Fig. 2, shown in 3, please earlier referring among Fig. 2 shown in the A-A cutaway view, wherein first brace 10 of firm joint device 100 is fixed in handrail 30 inboards of plastic material, this handrail 30 is provided with combined hole 31, and bury a metal material spacer 32 with through hole 321 underground in handrail 30 inside, and first brace 10 of firm joint device 100 is stretched in the combined hole 31 by handrail 30 inboards by the one-body molded engaging body that is convexly equipped with 11 on it, wherein the inner edge at combined hole 31 is replaced in engaging body 11 set apical margin 12 packings, and has the function of location, the ora terminalis of engaging body 11 withstands on the spacer 32 of handrail 30 in addition, stretch into the through hole 321 that combined hole 31 passes spacer 32 by a screw 40 by handrail 30 outsides, again in the screw 14 that the guiding position 13 by engaging body 11 imports screw 40 in order to screw connecting sheath zoarium 11, and first brace 10 is fixed with handrail 30.

See also shown in Figure 3 again, wherein second brace 20 connects solid on the seat 50 of bent plank material, this seat 50 is provided with combined hole 51, this second brace 20 utilizes its one-body molded rivet clasp body 21 that is convexly equipped with to stretch in the combined hole 51 of seat 50 of bent plank material, make engaging piece 22 set on this rivet clasp body 21 can embed bent plank seat 50 inside, with impact style rivet clasp body 21 is protruded ora terminalis riveted at combined hole 31 in the outside of seat 50 again, can finish the integrated structure of handrail 30 and office seating 50 like this.

Can one-body molded formation engaging body 11 on above-mentioned first brace 10 and second brace 20.

Can one-body molded formation rivet clasp body 21 on above-mentioned first brace 10 and second brace 20.

Because firm joint device 100 of the present utility model forms engaging body 11 and rivet clasp body 21 in integrated mode, formality and cost when this mode not only can be saved assembling, more can improve the solid ability of knot between firm joint device 100 and handrail 30 and the seat 50 greatly, through long-term use, this spacer 32 still can quite firmly be fixed on handrail 30 on the office seating 50, rocks or unsettled situation and be difficult for producing.
