Description

Improved chair cushion regulator

The utility model is a kind of chair cushion adjuster of improvement, is refer to a kind of user's of being convenient to operation, and part exchanging cost reduction person during fault.

In daily life, seat is upward closely bound up with the mankind's relation, through constantly exploitation and improvement, seat is to go improvement design towards the aspect of convenience, comfortableness mostly at present, and have more to height of seat adjustment and chair back angle of inclination designer, as shown in Figure 5, be the structure of at present general chair cushion adjuster, wherein mainly include wind 6, adjust seat 7, base 8 wherein:

Wind 6 tops are provided with a pivoted hole 61, and outer rim is shaped to off-centre operation, and wind 6 is adjusted on the seat 7 one side engagement grooves 71 in aftermentioned by a bolt pivot;

Adjust seat 7, mainly be provided with an engaging groove 71, and be provided with spring 72, axostylus axostyle 73 in this engaging groove 71, and axostylus axostyle 72 runs through by the central perforation 711 of engaging groove 71 and adjust seat 7, and an end is resisted by sheathed spring 73 in a side; Be respectively equipped with some trimmers 74, pad 75, cylinder 76, nut 77 to adjust seat 7 middle positions, wherein the two ends of each trimmer 74 are respectively equipped with perforation, and the end pad 75 that joins respectively, one end of each trimmer 74 is socketed on the axostylus axostyle 73 by perforation is arranged in parallel, other end perforation then is socketed on the bolt 81 of aftermentioned base 8 with 8 actions of control base; On trimmer 74 1 sides, be provided with cylinder 76 and the hold-doun nut 77 that is socketed on axostylus axostyle 73 in addition again, make cylinder 76, nut 77, trimmer 74 be the interlock state;

Base 8 is to be articulated in an end of adjusting seat 7, and is provided with in base 8 and articulates a side on bolt 81 and the bolt and be resisted against the torque spring 82 of adjusting seat 7, and is provided with bolt 83 again with the aforementioned trimmer 74 of winding on base 8, and by trimmer 74 controls;

When wind A composition surface, 6 top and axostylus axostyle 73 conflicts, then axostylus axostyle 73 is not compressed, make each trimmer 74 be closed state, base 8 can't be moved by trimmer 74 constraints;

And for example shown in Figure 6, when wind 6 being moved a little angle B composition surface and axostylus axostyle 73 are conflicted, then will compress spring 72 and interlock cylinder 76 simultaneously, nut 77 moves to right, each trimmer 74 can be removed because of the elastic force restraining force be relaxation state, and the user can adjust base 8 and the angle of adjusting seat 7 again, after adjusting, again wind 8 is adjusted to A composition surface and axostylus axostyle 73 applyings, can reaches the effect of adjustment.

The person adjusts comfortable chair cushion angle though right aforementioned structure utilizes the action of wind 6 to make things convenient for the seat, be to close face and 73 displacements of axostylus axostyle 73 conflict control axostylus axostyles only by the front end retaining because of wind 6, so after using a period of time, because of the long-term friction of composition surface and axostylus axostyle 73, make the composition surface to be worn and the axostylus axostyle 73 suitable displacements of can't conflicting, whole wind 6 promptly must be changed the waste that causes on the material;

Because of the extremely strong back stretch of spring 72 tools, make the seat person must take big strength beginning stretchy wind 6 again, it is inconvenient to cause use to go up.

The creator is after being engaged in seat design production many years of experience, because the disappearance situation in above-mentioned cost of parts and the use, be to give design improved again, generation of the present utility model is arranged eventually, its purpose promptly combines design at the drive block that wind is located in utilization with the linked block that designs in adjusting seat, make wind more easy to operate, and part exchanging cost reduction person.

Below, promptly cooperate the utility model description of drawings in the back:

Fig. 1 is an exploded view of the present utility model;

Fig. 2 is an assembled sectional view of the present utility model;

Fig. 3 is an enforcement illustration of the present utility model;

Fig. 4 is an enforcement illustration of the present utility model;

Fig. 5 system commonly uses product combination and implements schematic diagram;

Fig. 6 system commonly uses product combination and implements schematic diagram.

At first, see also Fig. 1, the utility model mainly comprises wind 1, drive block 2, linked block 3, adjusting seat 4, wherein:

Wind 1, lie in an end that is assembled in adjusting seat 4 and be provided with two joint fasteners 11, and the diameter of two joint fasteners 11 is less than drive block 2 diameters, and drive block 2 just can be inserted in the interval, the perforation 21 of corresponding

aftermentioned drive block

2,22 positions are provided with perforation 111 and bore a hole 112 on joint fastener 11 again, so that assembling drive block 2;

Drive block 2 is the circular block of being made by the high rigidity material, and central authorities and appropriate location, both sides be provided with

perforation

21,22, and making can be by affixed element assembling drive block 2 on wind 1; Be provided with the driving groove 23 of the some latches of tool again in drive block 2 one sides, to drive linked block 3 actions;

Linked block 3, the eccentric block that system is made by the high rigidity material, and establish the corresponding aforementioned groove of a pivoted hole 31, one sides 23 positions in central authorities and be provided with groove 32 with groove 23 equal number latches, linked block 3 opposite sides are established the suitably arc limit of half off-centre of tool again, and the projection that makes this arc limit is a press section 33;

Adjust seat 4, system includes engaging groove 41, axostylus axostyle 42, spring 43, trimmer 44, pad 45, sleeve 46, nut 47, and wherein the combining structure of axostylus axostyle 42, spring 43, trimmer 44, pad 45, sleeve 46, nut 47 is commonly used structure because of being analogous to, so will not state more, wherein:

Engaging groove 41, be that slightly larger in diameter is in aforementioned drive block 2 diameters, and the perforation 411,413 of slightly larger in diameter in pivot 412,414 arranged in the side appropriate location, make the central perforation 21 that pivot 12 can run through perforation 411, drive block 2 articulate drive block 2, and pivot 414 can run through perforation 413, the perforation of linked block 3 31 articulates linked blocks 3, and the groove 32 of the groove 23 of combination back drive block 2 and linked block 3 is to be engagement; The bottom group of engaging groove 4 is provided with axostylus axostyle 42, spring 43 in addition, and the end face of axostylus axostyle 42 system conflicts with the outer rim of linked block 3.

When the utility model combination is implemented, system is shown in Fig. 2,3, wherein drive block 2 is to be fixed on the joint fastener 11 of wind, and linked block 3, drive block 2 are to arrange to be hubbed on the engaging groove 41 of adjusting seat 4 and to be an interlock state, when the press section 33 of linked block 3 is not conflicted axostylus axostyle 42, then the trimmer 44 of adjusting seat 4 does not loosen, and base 5 can't move;

When spurring wind 1 again, can make that drive block 2 is corresponding to rotate, and drive piece 3 and rotate and make press section 33 compress axostylus axostyle 42, then will trimmer 42 be loosened because of axle 42 is extruded, pad 5 be removable.

For another shown in Figure 4, linked block 3 outer rims of the present utility model are protruding can be provided with inclined-plane 34 with crimping section, makes that linked block 3 can be the location when inclined-plane 34 conflict axostylus axostyles 42, makes base 5 can be swinging condition.

In sum, the design that combines of the utility model drive block 2 and linked block 3, make that the operator can mobile easily wind 1, easy to operate, and, need only change linked block 3 if use when worn and torn in linked block 3 surfaces long afterwards, must not change whole wind, cost of parts reduces, and it is good that its practicality is commonly used product in fact.
