Description

Convenient chair

The utility model relates to the convenient chair that the old man uses.

Existing convenient chair is made up of the back leg that connects together with the chair back, seat and chair foreleg with holes.Because this convenient chair can not fold, and promptly takes up room, inconvenience is carried again.

The purpose of this utility model provides a kind of convenient chair, and it is not only collapsible, and can be at folding back elder when the walking stick use.

The utility model is achieved in that convenient chair comprises the back leg that connects together with the chair back, seat and chair foreleg with holes, seat comprises an intermediate plate and two side panels, described hole is in intermediate plate central authorities, each side panel all links to each other with intermediate plate by hinge, torsion spring, spring movable lug, the seat intermediate plate links to each other with the chair back by hinge, the chair foreleg links to each other with above-mentioned side panel with bending pole by hinge, the seat intermediate plate back side has the slide rail that Bedpan is installed, the chair back and back leg are made of pole, and there is hook its upper end.When folding, at first foreleg is folded into the side panel back side, then side panel (containing foreleg) is folded into intermediate plate and be to tilt or vertical position, last, intermediate plate (containing side panel and foreleg) is folded on the chair back, utilize hook to fix.When opening, as long as anti-operation in tandem.After convenient chair is folding, can work as the walking stick use by elder.

Because seat of the present utility model can fold on the chair back, therefore both can take up space less, be convenient to the old man again and carry, because seat of the present utility model itself is also collapsible, thereby has reduced the width of seat, can work as walking stick and use.

Referring to Fig. 1,2,3,6, convenient chair comprises the back leg (2) that connects together with the chair back (1), seat (3) and chair foreleg (4) with holes.Seat (3) comprises an intermediate plate (5), two side panels (6).Each side panel (6) is all by hinge (7), torsion spring (8) and spring movable lug (9) link to each other with intermediate plate (5) (simultaneously referring to Fig. 6).Seat intermediate plate (5) links to each other with the chair back (1) by hinge (10).Chair back intermediate plate (5) back side has the slide rail (12) that Bedpan (11) is installed.The chair back (1) and back leg (2) are made of pole, and there is hook (13) upper end.The concrete structure of hook (13) is shown in Figure 14,15.Chair foreleg (4) links to each other with side panel (6) with bending pole (15) by hinge (14).The top in the hole (not drawing among the figure) of intermediate plate (5) is equipped with by hinge (17) and is renovated (18).Handle (19) is equipped with on chair back top.After the foreleg (14) of chair is folding, launch automatically in order to prevent foreleg (4), be provided with elastic projection (25) in the lower end of foreleg (4), play fixation (referring to Fig. 6) by the frictional force of itself and side panel (6) sidewall.

Referring to Fig. 4,5, bending pole (15) is combined by hinge (23) by two bars (21,22).Wherein a pole (21) has a block (20), its effect is after bending pole (15) expansion is crossed critical point (i.e. two poles point linearly), can prevent pole moving forward, bend pole (15) play a supportive role (referring to Fig. 2) this moment.The two ends of bending pole (15) are hinged on respectively on the side panel (6) of chair foreleg (4) and seat (3).

Referring to Figure 10,11, spring movable lug (9) is installed on the intermediate plate (5), has the hole (referring to Fig. 7) that holds movable lug on the side panel (6).When convenient chair launched, the movable lug head of Spring hinge (9) inserted in the above-mentioned hole and play supporting role.Spring movable lug (9) is a prior art, and its structure is drawn in Figure 10, needn't give unnecessary details.For control spring movable lug (9) easily, between every group of spring movable lug (9), be connected with a rope (24).Like this, when tension rope (24), just can make the withdrawal of two upper spring movable lugs (9) simultaneously.

Referring to Figure 12,13, the Bedpan (11) that the utility model slide rail (12) is installed comprises box body (26) and inserts lid (27).Inserting lid (27) mainly seals.There is the projection (28) that matches with slide rail (12) top in box body (26).During use, this projection (28) is installed in the groove of slide rail (12), and slidably.

Referring to Fig. 6,9, in the present embodiment, the intermediate plate (5) of seat (3) and side panel (6) all adopt " ㄇ " shape structure, can prevent that so relevant parts from exposing chair and influencing its outward appearance outward, also provide convenience for open the hole that holds spring movable lug (9) on side panel (6) simultaneously.

When present embodiment launches as shown in Figure 1, 2.When folding, at first will bend pole (15) along the bending of direction shown in the arrow, foreleg this moment (4) just is folded back onto in " ㄇ " shape structure of side panel (6).With the rope (24) that pulls moving seat (3) back side, make spring movable lug (9) withdrawal again, side panel this moment (6) is upwards dug under the effect of torsion spring (8), be state shown in Figure 9, at last, seat (3) is folded back onto on the chair back (1), tangles and get final product with hook (13).Convenient chair after folding is shown in Fig. 7,8.When this convenient chair is opened, as long as anti-operation in tandem.
