Description

Variable chair

Technical field

The utility model relates to field of furniture, and more particularly, it relates to a kind of variable chair.

Background technology

Chair is a kind of also armed thing to sit on having backrest, have.In general, armed chair is commonly referred to as elbowchair, and and be not armedly called chair.

In fact, because armchair can block right-hand man by lattice, more inconvenient in family's life process, so usually adopt chair in life a few days ago, but chair has lacked handrail for the elderly playing seat inconvenience, the elderly of legs and feet inconvenience does not prop up health by handrail, is again a large matter of regret; So need now the chair of a kind of comprehensive armchair and chair advantage, in use just as chair, when needs stand, there is again the armchair that handrail can support.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of variable chair can regarding again chair as armchair.

For achieving the above object, the utility model provides following technical scheme: a kind of variable chair, comprise chair body, described chair body comprises chair leg, seat and the chair back, and described chair leg is arranged on the bottom of seat, and the described chair back is arranged on seat, described seat is hinged with T-shaped handrail, the both sides, front and back of described T-shaped handrail are respectively arranged with clamping block, the described chair back are provided with the first lock slots matched with clamping block, and adjacent described chair leg is respectively arranged with the second lock slots coordinated with clamping block.

As preferably, described clamping block comprises the first projection and the second projection, and an end face of described first projection is fixedly connected with T-shaped handrail, and the other end of described first projection is fixedly connected with the second projection, and the diameter of described second projection is greater than the first projection.

As preferably, described lock slots comprises the first groove and the second groove that are interconnected, and described first groove matches with the first projection, and described second groove matches with the second projection.

As preferably, the left and right sides of described chair body offers groove, and the both sides of the lower end of described T-shaped handrail are provided with spill spin block, and the two side of described groove is provided with the swivelling chute coordinated with spill spin block.

As preferably, described swivelling chute is the oblong slots in vertically arranging, and described first groove and the second groove are extended with the 3rd lock slots downwards.

By adopting technique scheme, T-shaped handrail in the utility model is rotated down, then the clamping block inlay card of T-shaped handrail enters in the second lock slots, namely the locking between T-shaped handrail and adjacent chair leg is completed, strengthen the structural strength of chair leg, simultaneously when needs use handrail, T-shaped handrail is rotated up, when then the clamping block inlay card of T-shaped handrail being entered the first lock slots, namely T-shaped handrail is fixed with the chair back, now namely T-shaped handrail uses as handrail, change the T-shaped handrail of variable chair by rotating up and down, chair can be regarded again as armchair, easy to use, meet the demand in life.

Detailed description of the invention

Referring to figs. 1 through Fig. 7, embodiment of the present utility model is described further.

As shown in Figure 1, a kind of variable chair, comprise chair body 0, chair body 0 comprises chair leg 01, seat 02 and the chair back 03, chair leg 01 is arranged on the bottom of seat 02, the chair back 03 is arranged on seat 02, seat 02 is hinged with T-shaped handrail 1, the both sides, front and back of T-shaped handrail 1 are respectively arranged with clamping block 3, the chair back 03 is provided with the first lock slots 4 matched with clamping block 3, adjacent chair leg 01 is respectively arranged with the second lock slots 5 coordinated with clamping block 3, T-shaped handrail 1 is rotated down, then clamping block 3 inlay card of T-shaped handrail 1 enters in the second lock slots 5, namely the locking between T-shaped handrail 1 and adjacent chair leg 01 is completed, strengthen the structural strength of chair leg 01, simultaneously when needs use handrail, T-shaped handrail 1 is rotated up, when then clamping block 3 inlay card of T-shaped handrail 1 being entered the first lock slots 4, namely T-shaped handrail 1 is fixed with the chair back 03, now namely T-shaped handrail 1 uses as handrail, change the T-shaped handrail 1 of variable chair by rotating up and down, chair can be regarded again as armchair, easy to use, meet the demand in life.

As shown in Figure 7, the end face that clamping block 3 comprises the first projection 31 and the second projection 32, first projection 31 is fixedly connected with T-shaped handrail 1, and the other end of the first projection 31 is fixedly connected with the second projection 32, and the diameter of the second projection 32 is greater than the first projection 31.

As shown in Figure 4, first lock slots 4 and the second lock slots 5 comprise the first groove 412 and the second groove 422 be interconnected, first groove 412 matches with the first projection 31, second groove 422 matches with the second projection 32, when T-shaped handrail 1 is between chair leg 01, the side of the second groove 422 clamps by the second projection 32, prevents the structural strength between chair leg 01 not high.

As shown in Figure 2 and Figure 7, the left and right sides of chair body 0 offers groove 2, the both sides of the lower end of T-shaped handrail 1 are provided with spill spin block 11, the two side of described groove 2 is provided with the swivelling chute 21 coordinated with spill spin block 11, T-shaped handrail 1 coordinates by spill spin block 11 and swivelling chute 21 the rotation realizing T-shaped handrail 1, and T-shaped handrail 1 also can realize the rotation of T-shaped handrail 1 by the mode of hinge or hinge simultaneously.

As shown in Figure 5, swivelling chute 21 is the oblong slots in vertically arranging, second groove 422 is extended with the 3rd lock slots 6 downwards, in use, after clamping block 3 inlay card is entered the first lock slots 4 or the second lock slots 5 by T-shaped handrail 1, by T-shaped handrail 1 to pressing down, then clamping block 3 just enters in the 3rd lock slots 6, spill spin block 11 is also at swivelling chute 21 simultaneously, namely move down in oblong slots, now T-shaped handrail 1 cannot outwards rotate, namely the locking of T-shaped handrail 1 is completed, prevent T-shaped handrail 1 from locking unstable situation, prevent the T-shaped handrail 1 when body support from rotating the situation causing user's tumble injury to the left and right, when needing to change T-shaped handrail 1 simultaneously, only T-shaped handrail 1 upwards need be mentioned, namely rotatable.

The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
