The specific embodiment

For purpose, characteristic and effect to the utility model can have further understanding and understanding, following conjunction with figs. is enumerated embodiment, and detailed description is as back:

At first, to shown in Figure 4, it includes: a seat body (10), a fixed mount (20), an adjustable shelf (30), two bolts (40), two knobs (50) and a chair back (60) like Fig. 1; Wherein, seat body (10) has a base (11), and base (11) rear is extended with a column (12) toward tilting; Column (12) is provided with first Coupling (14) of accepting seat cushion (13) and second Coupling (15) of accepting the chair back (60), and first and second Coupling (14) (15) is gone up and is provided with quick detach (16), with loosening and packing of this quick detach (16); Can reach seat cushion (13) and the upper and lower adjusted location of the chair back (60), base (11) is provided with extended several legs (17) again, and leg (17) below respectively is provided with a pulley (18); Fixed mount (20) is to establish to be " ㄇ " shape, makes this fixed mount (20) have a top board (21) and two side plates (22), and two side plates (22) are gone up preset place and respectively provided a through hole (23); The terminal past interior a bit of bottom bracing sheet (24) that respectively is bent with encloses with the frame of bottom bracing sheet (24) through this top board (21), side plate (22), and military order fixed mount (20) inside can become a conduit (25); And this fixed mount (20) is combined on second Coupling (15), and in order to do extending toward second Coupling (15) the place ahead, adjustable shelf (30) has one first pivot seat (31); First pivot seat (31) rear is equipped with one and cooperates external member (32); This cooperation external member (32) is to establish to be " ㄈ " shape, makes it have two parallel Extendible flakes of being separated by (33), and two Extendible flakes (33) are gone up and each level is provided with an elongated slot (34); Adjustable shelf (30) is placed in the conduit (25) of fixed mount (20) with two Extendible flakes (33) that cooperate external member (32) again; Make adjustable shelf (30) go up the forward and backward slippage of generation with the cover group of conduit (25) at fixed mount (20), and when adjustable shelf (30) was placed in the conduit (25) with two Extendible flakes (33), military order elongated slot (34) can keep relatively with through hole (23) to cooperate external member (32); Bolt (40) has the retaining edge (42) that a keying rod (41) and enlarges; Fixture block (43) with a cubic shape between keying rod (41) and retaining edge (42) joins, and this two bolt (40) promptly is placed in the conduit (25) of fixed mount (20), and the elongated slot (34) that passes both sides with keying rod (41) in regular turn stretches out with through hole (23) more outward; Should be after stretching out; Fixture block (43) can be taken advantage of a situation inlay card in elongated slot (34), and in order to do the stop that bolt (40) is formed rotation, knob (50) inner face is extended with the combined hole post (51) of a tool internal thread; The keying rod (41) outer with stretching out in fixed mount (20) with this combined hole post (51) produces screw lock; Military order adjustable shelf (30) can be clamped be fixed between retaining edge (42) and side plate (22), the chair back (60) rear be provided with one with the second pivot seat (61) of adjustable shelf (30) first pivot seats (31) generation pivot group, the second pivot seat (61) is provided with a protuberance (62); Through this protuberance (62) location is provided, can between the chair back (60) and adjustable shelf (30), presss from both sides if with a spring (70) is arranged.

The use of its structure is when desire is adjusted the forward and backward position of the chair back (60), through the rotation of knob (50); Drive bolt (40) pine and move back, two Extendible flakes (33) of adjustable shelf (30) can be loosened do not clamp, in order to do directly utilizing the slippage of cooperation external member (32) in fixed mount (20) conduit (25); Drive the chair back (60) and advance or retreat (please consulting Fig. 5 and Fig. 6 simultaneously), visual user's build is different, and cooperates; To obtain best position, when the adjustment translation, because bolt (40) is to be fixed in the through hole (23); So bolt (40) can be in the transfixion state, and adjustable shelf (30) utilizes elongated slot (34) when slippage, to provide fixture block (43) to dodge, then visual elongated slot (34) is offered the length of distance; Come the maximum of the chair back (60) adjustment shift motion is carried out standard, avoiding adjustable shelf (30) unrestricted, and directly slippage goes out fixed mount (20); And after the chair back (60) adjustment finishes, utilize the reverse rotation of knob (50) again, drive bolt (40) and lock again; Let Extendible flake (33) can be in clamped state once again, the adjusted state of the chair back (60) then can obtain to keep.

Again; Utilize the first pivot seat (31) and the second pivot seat (61) relation of pivot group mutually; Make the chair back (60) on adjustable shelf (30), carry out swing by a small margin; To make the chair back (60) can be obedient to user's back fully, should when swing, can also utilize spring (70) resilient support, reach the effect (please consulting Fig. 7 simultaneously) of bumper and absorbing shock.

In addition, respectively be provided with depressed part (26) (35) on the fixed mount (20) and the first pivot seat (31), to be used for cooperating two bands (80) and a baffle (90) to use; This two band (80) is tightened respectively in the depressed part (26) (35) that is fastened on the fixed mount (20) and the first pivot seat (31); Let baffle (90) one ends can see through tightening of band (80), and by clamping between band (80) and fixed mount (20), baffle (90) other end then extends toward the chair back (60) direction; With by clamping between another band (80) and the first pivot seat (31); Through this design, will let baffle (90) can be located at fixed mount (20) and adjustable shelf (30) foreign side fully, expose to avoid internals; And influence attractive in appearance, and this baffle (90) on be formed with continuous fold (as shown in Figure 8).

The structure of the above-mentioned specific embodiment of mat can obtain following technique effect: (one) its chair back (60) can carry out forward and backward adjustment, so will more suit measures to different persons in the use, it is best by putting effect that the chair back (60) can be brought into play; (2) its chair back (60) can carry out forward and backward adjustment, so even if child's height, build constantly change, this chair back (60) also can be adjusted cooperation in real time, lets the child can form good reading posture; (3) it only needs turning knob (50) just can accomplish the adjustment action of the chair back (60) rapidly, and difficulty effectively simplifies the operation.

Only the above person is merely the preferred embodiment of the utility model, when can not with the scope implemented of qualification the utility model; The equalization of promptly being done according to the utility model claim generally changes and modifies, and all should still belong in the scope that the utility model patent contains.
