Abstract
The utility model relates to a row chair with automatic turnover seat. At present, the stationary-type row chair utilized in the most meeting places, the bracket is very heavy, and the transport, the installation and the maintenance of the chair are very inconvenient; When the seat board rotating shaft is arranged on the bracket, the stability of the rotating shaft is bad; the reversal of the seat board is not under-control, the impact sound between the seat board and the backing plate is loud. The utility model is characterized in that: a rotating shaft is formed by the central thimble and the fixed principal axis, the central thimble is arranged on the mounting bracket of the seat board, and the fixed principal axis is suited in the side sleeve of the end of the cross-arm; an end of the offsetting spring which is suited on the central thimble is caught on the stationary shaft in the sleeve, The other end of the offsetting spring is caught on the spring stationary shaft of the mounting bracket of the seat board, and the spring stationary shaft in the sleeve is inserted in the slider of the mounting bracket. By utilizing the utility model, the seat board is on the horizontal position and the center of gravity is fell on the rotating shaft, with the control from the slider of the mounting bracket of the seat board and the built-in spring stationary shaft of the sleeve, the seat is maintained stable; with the effect of the offsetting spring and the control from the slider and the built-in spring stationary shaft, the seat board does not impact with the seat back when the seat board is up turned for 90 DEG, and no sound generates during the reversal. The utility model has the advantages of simple structure and low production, etc.
Description
Technical field
The utility model relates to a kind of row's chair, definitely says so to relate to a kind of fixedly row chair that is suitable for setting in the convention Rooms such as meeting-place, cinema, school, lecture theater, music hall, the performance Room.
Background technology
At present, fixed row's chair of use is set in cinema, the convention Room, the performance Room, has following shortcoming: 1. arrange the chair support overwhelming majority and be the solid casting of cast iron, Heavy Weight, transportation, installation, maintenance are very inconvenient; 2. arrange the left and right sides rotating fulcrum of chair seat board, rack-mount, not on the symmetrical centre axis of the front and back of seat board, but in the relatively front portion installation of seat board central axis, cause seat board long at the lower part of rotating shaft seat surface, the top seat surface is short, owing to be that seat board is blocked in the backboard lower end, need when taking one's seat to keep the seat board balance by human body, so this structural stability extreme difference, human body leaves seat surface, seat board will upwards overturn, because center of gravity is or not the center of seat board but after leaning on, during the human body leans back, the center of gravity disequilibrium, turn over the human body tenesmus on the seat board, seat gets up extremely uncomfortable; 3. for keeping seat board stability preferably, seat board plate face must extend, and not only waste material causes with front-seat narrow at interval the seat inconvenience of coming in and going out again; 4. because rotating shaft is rack-mount, owing to turn on the seat board and backboard bumps against, the sound is very big when leaving the seat, hinders peripheral people and pays attention to the class or watch performance.
Summary of the invention
Goal of the invention of the present utility model is: overcome the present shortcoming that exists at above-mentioned row's chair of usefulness, for the user provides a kind of, transportation in light weight by having of making of hollow sting, installation, maintenance convenient, take one's seat good stability, the seat comfortable, disseating automatically, the no sound of upset does not influence other people, wide with front-seat spacing, the convenient automatic convertible row's chair of portable and stable of coming in and going out.
Goal of the invention of the present utility model realizes by implementing following technical proposals:
The automatic convertible row's chair of a kind of portable and stable, form by the single chair that is connected into a row, each single chair all is by a left side, support on the right two foundation seats, be loaded on the handrail on the support upper armrest frame, be installed in a left side, backboard on the right two stands medial branch fagging, be installed in a left side, seat board on the distolateral rotating mechanism of right two stands bottom crossbearer constitutes, every two adjacent single chairs, all has a shared base support, the left side, crossbearer termination of this support, right both sides, the rotating mechanism that an installation seat plate is respectively arranged, it is characterized in that: the rotating mechanism of installation seat plate on the crossbearer termination, support bottom, be by being fixed on the crossbearer front end side wall, by outer sleeve, be positioned at the fixed main shaft at its center, and the fixation kit that constituted of a termination fixed axis that is in the back-moving spring at fixed main shaft rear portion and the runner assembly adaptive with it are formed; This runner assembly is a seat board fixed mount with center sleeve, spring fixed axis and chute, its center sleeve is positioned at the fixedly middle and lower part of frame plate, when cooperating with fixation kit, this sleeve pipe is adorned on the fixed main shaft that is inserted in the letter of fixation kit overcoat, and sleeve pipe is set with back-moving spring outward; This spring fixed axis be positioned at center sleeve below, its cover stick back-moving spring another the compression termination; Chute is positioned at the center sleeve back upper place, and the back-moving spring fixed hub in the fixation kit outer sleeve inserts in it; Seat board is installed on the gripper shoe on the seat board fixed mount; Runner assembly matches with fixation kit, and spring is compressed when human body is taken one's seat, and seat board keeps level, when disseating, under the effect of spring restoring force seat board is upwards overturn 90 ° from horizontal plane.
Additional technical feature of the present utility model is: 1. constitute the support of row's chair, be the column support of hollow ellipse shape for a kind of cross section.2. on the axostylus axostyle of back-moving spring termination fixed axis, be set with in the time of can preventing effectively that chute from sliding in outer sleeve, cover inserts in the yielding rubber cover of this axostylus axostyle bump chute termination generation sound in it.
Advantage of the present utility model is:
1. owing to change the solid support of cast iron into plastics or the hollow pylon of steel, the row's of making chair main member weight alleviates greatly, is convenient to transportation, I﹠M;
When 2. taking one's seat owing to human body, the center of gravity of seat board is in the rotating shaft of seat board fixed mount, promptly be set with on the center sleeve of seat board fixed mount of fixed main shaft, the while seat board is the following rear end of frame plate face upper hopper chute fixedly, firmly blocked by the back-moving spring fixed axis in the outer sleeve of crossbearer end, thus the seat stable be seated comfortable;
3. because seat board when being in level, its center of gravity drops in the rotating shaft, and good stability can suitably dwindle seat board plate face, promptly economizes material and makes again with front-seat and suitably relax at interval, is convenient to come in and go out;
4. because the turning cylinder of seat board is mounted in the crossbearer end of support, directly be not contained on the support, when human body left seat board, under the effect of rotating shaft back-moving spring restoring force, seat board is upset upwards, the fixing preceding upper end of chute on the frame plate face of seat board simultaneously, the spring fixed axis that firmly is reset blocks, and can only overturn 90 °, and can not clash into backboard, thereby the no sound of seat board upset, do not influence peripheral people.In addition, but that the utility model also has is simple in structure, the one-shot forming of main part support is made, outstanding advantages such as cost of manufacture is low, structural strength is big, handsome in appearance, convenient installation.
