Abstract
The utility model discloses chair armrest regulating mechanisms which comprise gear position blocks arranged on armrests and regulating blocks matched with the gear position blocks, wherein each gear position block is an inverted U-shaped frame body of which both ends are provided with short U-shaped inner folding edges; the gap between the two inner folding edges is slightly greater than the thickness of each regulating block penetrating through the gap; a main body part of each gear position block is arranged at the inner part of each armrest, and the bottom of the inner side of each gear position block is provided with the left and the right rows of a plurality of limit stops which are distributed in a parallel mode. A main body of each gear position block of each chair armrest regulating mechanism is arranged at the inner part of each armrest, exposed parts are the short U-shaped inner folding edges, and thus, the utility model avoids that fingers, clothing, etc. are clamped in the regulating mechanisms of the armrests. The utility model has the advantages of high safety, simple structure, less material consumption, low cost and beautiful appearance, and simultaneously, the utility model reduces the body shape of each entire armrest regulating mechanism.
Description
Technical field
The utility model relates to a kind of chair, is specifically related to the armrest adjustment mechanism of chair.
Background technology
At present, the adjustable chair of handrail on the market, its handrail is regulated part and generally is designed to the flute profile governor motion that opens wide, promptly on handrail, be provided with the gear piece of some grooves and the regulating block that cooperates with the gear piece, in the outside unshielded measure of flute profile piece, its maximum deficiency of this structure be when people regulating the chair back and open or folding process in, be easy to folders such as finger or coat-sleeve are advanced in the groove of governor motion, cause the injury of human body or the damage of clothing; Improved, a simple protective cover is set, and existing protective cover is located at all and is connected the handrail outside outside the gear piece, its profile is bigger, and it is big, also not attractive in appearance to take up room.
The utility model content
In order to make people in regulating the handrail process, avoiding pointing clothing etc. is snapped in the governor motion of handrail, reducing it takes up space, the utility model discloses a kind of armrests governor motion, can avoid pointing clothing etc. and be snapped in the governor motion of handrail, profile is less, occupies little space, simple in structure, safety easy to use.
To achieve these goals, the technical solution adopted in the utility model is: a kind of armrests governor motion, comprise gear piece of being located on the handrail and the regulating block that cooperates therewith, the regulating block top is provided with stop block, it is characterized in that: the main part of described gear piece is located at handrail inside.
As of the present utility model a kind of preferred, described gear piece is the inverted U-shaped framework of flanging in the band of two ends, and the space between the described two interior flangings is slightly larger than the thickness that passes regulating block wherein, is provided with some blocks in gear piece inside.
For when operation more safety and finger do not have discomfort when running into, flangings are short U-shaped flanging or horizontal flanging in described two.
As of the present utility model a kind of preferred, described stop block is located at the front side on regulating block top, and the rear side on regulating block top is provided with the projection that is higher than stop block, is provided with like this, and it is more easy and convenient that gear is regulated.
As of the present utility model a kind of preferred, described some blocks and gear piece are structure as a whole, and block forms for punching out on the gear piece, and this structure is simpler, and processing and fabricating is convenient.
As of the present utility model a kind of preferred, described stop block and regulating block are structure as a whole, and stop block is for bending forms in the regulating block end, and this structure is simpler, and processing and fabricating is convenient.
As a kind of improvement of the present utility model, some blocks of the parallel distribution of two rows about establish described gear piece inside.
The utility model is owing to adopt technique scheme, the gear piece main body of armrests governor motion is located at handrail inside, and exposed parts is short U type invagination, avoided finger clothing etc. to be snapped in the governor motion of handrail, safe and reliable, very simple of structure, consumptive material is few, cost is low, and the bodily form and the institute that have also dwindled whole armrest adjustment mechanism simultaneously take up space, and make it more attractive in appearance.

The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation;
Fig. 2 is an A-A cutaway view among Fig. 1;
Fig. 3 is handrail partial structurtes schematic diagrames;
Fig. 4 is the utility model gear block structure schematic diagram;
Fig. 5 is Fig. 4 upward view;
Fig. 6 is the utility model regulating block structural representation;
Fig. 7 is that the C of Fig. 6 is to view.
The specific embodiment
As depicted in figs. 1 and 2, be the embodiment of the utility model armrests governor motion, 1 is handrail among the figure, and 2 is the gear piece, and 3 is regulating block, and 4 is the chair foreleg, and 5 is the chair back leg.
As Fig. 3, handrail 1 inside is provided with the mounting groove 11 corresponding with gear piece 2, and the main part of gear piece 2 promptly is embedded in the mounting groove 11 of handrail 1.
As Fig. 4 and Fig. 5, gear piece 2 is slightly larger than the thickness d of the regulating block 3 that passes wherein for the inverted U-shaped framework of flanging 21 in the short U-shaped of two ends band, the space 22 in this two short U-shaped between the flanging 21, as shown in Figure 6.The interior flanging 21 of gear piece 2 is short U-shaped, can be safer when operation, and finger does not have discomfort yet when running into, flanging also can be the horizontal flanging parallel with the handrail lower surface in this.The two bottom sides of gear piece 2 inside also respectively is provided with the block 23 of 3 parallel distributions, and the direct punching out on gear piece 2 of these 6 blocks 23 is come out, and is simple in structure like this, processes easier for installation.
As Fig. 5 and Fig. 6, the front side on regulating block 3 tops is provided with stop block 31, and rear side is provided with the projection 32 that is higher than stop block 31.Described stop block 31 is structure as a whole with regulating block 3, and stop block 31 is for bending forms in regulating block 3 ends, and this structure is simpler, and processing and fabricating is convenient.
As Fig. 1, regulating block 3 bottoms are installed on chair foreleg 4 and the chair back leg 5 by bolt 6, the space 22 that regulating block 3 tops are passed on the gear piece 2 cooperates with block 23, stop block 31 is stuck on the block 23, projection 32 withstands on gear piece 2 tops, like this, can be more easy and convenient when regulating the armrests gear.
