Reverse operating, when seat plate 222 rises towards horizontal position, end enters positioning device thereafter, and latch hook 21222 is in spring force
The V-shaped groove 2223 of seat plate rear end is caught under effect, seat plate is locked in this position, just takes class for student with standard gestures.
Embodiment two
The embodiment of the present invention two and example one are essentially identical, do not exist together and are only that the long pivot hinge of the radial type plate for sitting and leaning 22a of this example
2221 hinged shaft outer end is provided that guide sleeve 22212, and guide post 221a12 is arranged in the lower part frame 221a1, and guide sleeve 22212 and guide post are sliding
Cooperation, when tablet chair is used as seat, guide sleeve is up slided along guide post, is risen by the dynamic lower backup plate 221a3 of the hinged shaft with of long pivot hinge,
The back of backup plate 221a2 is overlapped, as shown in Figure 3.When tablet chair 20 is used as chaise longue, guide sleeve slides into its bottom along guide post down
Portion drops to bottom by the dynamic lower backup plate 221a3 of the hinged shaft with of long pivot hinge, and comes below backup plate 221a2, while seat plate
222 rear portion also drops to extreme lower position, constitutes obtuse angle with radial type backboard and intersects, forms chaise longue state.Fig. 3 is frame with
There is the partial view of the radial type plate for sitting and leaning 22a of guide post.
Embodiment three
The embodiment of the present invention three and example one are essentially identical, as shown in Fig. 4-6, do not exist together and are only that: the plate for sitting and leaning of the tablet chair 20
Component 22 is guide tracked plate for sitting and leaning 22b, and backboard 221 is guide tracked backboard 221b, and guide tracked backboard includes guide frame
212 upper end of backrest leg of frame 221b1 and back plate 221b2 fixed thereto, chair frame 21 are equipped with guide wheel 2121, guide tracked backrest
The top of plate is connect with the guide-track groove of 212 upper end of backrest leg guide rail frame with 2121 interaction of guide wheel, 222 rear portion of seat plate with
Guide tracked backboard 221b is hinged, and backrest leg 212 is equipped with positioning device 2122；When tablet chair is used as seat, guide tracked backrest
Plate is in abut backrest leg 212 close to vertical direction, is supported on the hinge of positioning device 2122 and chair leg 213 before and after seat plate 222,
Seat plate 222 is locked in close to horizontal position by positioning device 2122；When tablet chair 20 is used as chaise longue, positioning device 2122 is opened,
It is first rotated counterclockwise and then is moved down with the guide tracked backboard 221b of Manual-pushing and be turning finally to terminal, while forward by seat plate
Passage is allowed to intersect with backboard composition obtuse angle, forms chaise longue state.
Leg 213 be in " Π " font, vertical portion be angular cross section, with steel plate bending weld or with plastics,
Metal-molding molding；Chair leg top is fixed with handrail 2131, and this example handrail is the formula handrail 2131a that is connected, and rivet or weld is in chair
On leg.,
Example IV
The embodiment of the present invention four and example three are essentially identical, as shown in Figure 7,8, do not exist together and are only that:
Rack gear 221b11 is equipped in the guide rail frame 221b1, the guide wheel 2121 is gear type guide wheel 21211, and the two is mutual
Engagement, gear type guide wheel are equipped with crank 2123 fixed thereto;When tablet chair 20 is adjusted to chaise longue from seat, positioning is first opened
Then device 2122 rotates counterclockwise crank 2123, rotate counterclockwise guide tracked backboard 221b first and then move down most
After go to terminal, while seat plate being elapsed forward, is allowed to constitute obtuse angle with backboard and intersect, formation chaise longue state.Conversely, working as class
When chair 20 is restored to seat from chaise longue, above procedure is executed in reverse order.
Embodiment five
This example is to form the technical solution that array uses with the desk and chairs of the various embodiments described above, as shown in Figures 9 and 10, this example be
The simplification structure designed on the basis of above each example.The invention belongs to teaching facilities, be all tens people the same classroom simultaneously
It uses, a student uses a set of desk 10 and a set of tablet chair 20, constitutes a set of desk and chair assembly, independently can use and adjust
Section, to keep classroom neat appearance, multiple assemblys can be used with tandem forming array, and entire classroom can also seem neat
It is standardized, methodically.
When forming array, bearing support 1211 is set, table cabinet 11 is connected to bearing support 1211 on the vertical columns 121 of desk 10
On, a set of desk 10 and a set of tablet chair 20 constitute a set of sitting-lying double-purpose desk and chair assembly, and multiple assembly tandems are constituted
The table pedestal 13 of the bearing support 1211 of rear assembly and desk in use, is fixed on the backrest leg 212 of preceding assembly by array
On, so that preceding group of backrest leg 212 is merged into a single whole with the vertical columns 121 organized afterwards, thus by the vertical columns of intermediate combination
121 save and do not have to.When the present invention uses sitting and lying can unrestricted choice, it is non-interference, it is not necessary to impose it is consistent, with very big flexible
Property, as shown in Figure 10.It is completely compatible with existing product since outer dimension is identical as existing desk and chair, so part is left home very
Close student can still continue to use traditional desk and chair, after all cost or lower, and entire classroom can be partially using the present invention, this is right
Popularization and application of the invention provide a possibility that bigger.
In addition, in some biggish classrooms of desk and chair fore-and-aft clearance, as primary school's classroom desk chair fore-and-aft clearance reaches regulation
