The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
Such as Fig. 1 to anti-bow-backed seat shown in Figure 6, comprise the chair back 1 and two two chair legs 2 near the chair back 1 one sides, chair leg 2 comprises first leg 201, second leg 202, intermeshing the first tooth bar 203 and the first gear 204, first leg 201 is tubular structure, and a side is provided with rod slide groove 206, inside is fixed with the first tooth bar 203, second leg 202 inserts in first leg 201, and can be near vertical direction and first leg 201 mutual translations, also be connected with back-moving spring 205 between first leg 201 and second leg 202, be used for first leg 201 is strutted certain distance with second leg 202.
Should also comprise the sitting posture sensing cell by anti-bow-backed seat, it comprises, one side is provided with the backrest 302 of the second tooth bar 301, spring 303, and with the second gear 304 and the gear-box 305 of the second tooth bar 301 engagements.Backrest 302 is positioned at the on the lower side position of side of the chair back 1, can by allowing the user bend over, see that the contact point of its back and the chair back 1 is determined particular location.Backrest 302 is connected on the chair back 1 by spring 303, and the second tooth bar 301 is aimed at the chair back 1, and the hole from the chair back 1 passes, and backrest 302 can move relative to the chair back 1 when being under pressure, and band carry-over bar 301, and gear 304 is rotated.Gear 304 is installed in by gear-box 305 on the back side of the chair back 1, gear 304 be provided with can winding wire rotary gear shaft 306.Spring 303 is used for backrest 302 is resetted.
Should also comprise locking device by anti-bow-backed seat, and be used for locking the first tooth bar 203 and the first gear 204, it comprises, is provided with the connecting rod 402 of ratchet 401, the ratchet 403 that cooperates with ratchet 401 and for the line 404 of drive ratchet 403.One end of described line 404 is connected with ratchet 403, and the other end is wrapped on the rotary gear shaft 306, and can or unreel by rotary gear shaft 306 rotation rollings.(when suitable the length of line is) connecting rod 402 two ends are located at respectively in the rod slide groove 206 on the chair leg 2, and can slide therein, two ends of connecting rod 402 are fixedly connected with the first gear 204 respectively, so that two the first gears 204 are when moving simultaneously on the first tooth bar 203, but drivening rod 402 moves together.Ratchet 401 is fixed on the paracentral position of connecing of connecting rod 402.Locking device has two states, and during locking state, ratchet 403 snaps in ratchet 401, and connecting rod 402 can not rotate, and during released state, ratchet 403 breaks away from ratchet 401, and connecting rod 402 can rotate.
Operation principle that should anti-bow-backed seat is, during unmanned the use, backrest 302 under the support of spring 303 with the chair back 1 at a distance of setpoint distance.Ratchet 403 snaps in ratchet 401, and connecting rod 402 can not rotate, and the first gear 204 can not move mutually at the first tooth bar 203, keeps static between first leg 201 and second leg 202 thereby make.Line 404 is tightened and is wrapped on the rotary gear shaft 306, and first leg 201 and second leg 202 spring 205 that is reset struts certain distance.
During use, if people's sitting posture is correct, its back do not contact with backrest 302 or contact force very little, can not oppress backrest 302 and move, this moment, anti-bow-backed seat can not change.
If people's sitting posture is not rectified, contacting more energetically occurs in its back and backrest 302, then can oppress backrest 302 and move to the chair back 1, moves just can drive the second tooth bar 301, makes 304 rotations of the second gear.Line 404 by rolling, just can drag ratchet 403 and break away from from ratchet 401 when the second gear 304 rotates, and just can mutually move between such the first gear 204 and the first tooth bar 203.Because people's Action of Gravity Field, shorten downwards with first leg 201 relative second legs 202 of the first tooth bar 203, by to back-moving spring 205 elastic force adjusting, the contract by distance of first leg 201 can be adjusted to smaller amplitude.This moment, the people can be because being subject to the slight unbalance prompting of receiving, thus the change sitting posture.
When the answer of people's sitting posture was rectified, first leg 201 was returned to the starting position under the support of back-moving spring 205.Backrest 302 is returned to the starting position under the support of spring 303, the revolution of the second gear 304 unreels line 404, and ratchet 403 snaps in the ratchet 401 again, realizes firmly being connected between first leg 201 and second leg 202.
In other embodiments of the present invention, also wantonly one or more chair leg can be arranged to aforesaid first leg and second leg structure.
In other embodiments of the present invention, also can be that second leg is tubular structure, the first tooth bar is fixed in inside, and first leg inserts second leg near the translation on the vertical direction, but the first gear is fixed on first leg by connecting rod.
Of the present invention a kind of preferred embodiment in, the chair back 1 also is provided with folding chair back 101, folding chair back 101 upper ends are connected in the chair back 1 top, the lower end can rotate around the upper end, and can when pressurized, promote backrest 302, folding chair back 101 is used for supporting people's back, obtains comfort.
Of the present invention a kind of preferred embodiment in, locking device also comprises a fixed pulley 405, fixed pulley 405 is located on the chair back 1, line 404 is through fixed pulleys 405, and at its surface sliding, this line-transect 404 can drive ratchet 403 more smoothly.
Above embodiment only is used for explanation the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; in the situation that do not break away from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
