Abstract

The invention relates to a seat-back-linked dual-purposed seat comprising a supporting frame, a seat back, and a seat cushion. A gear is arranged on the side of the supporting frame. Locks used for fixing the seat cushion are arranged on the front of the supporting frame. The seat back surrounds the periphery of the seat cushion, such that an unenclosed fence is formed. A first rack is arranged on the inner side of the seat back. A spring is arranged on the bottom of the seat cushion. A second rack is arranged on the side of the cushion. Teeth on two sides of the gear are respectively engaged with the first rack and the second rack, such that two transmissions on opposite directions are formed. The seat provided by the invention has the advantages that the seat is dual-purposed. The seat can be used as a footstool or an armchair. A switching operation between the two states is simple, and space occupation is low.

Description

The dual-purpose thing to sit on of seat back of the body linkage type

Technical field

The present invention relates to a kind of the dual-purpose thing to sit on of back of the body linkage type.

Background technology

Thing to sit on is close is contacting having a rest and working of people, and different sitting and lying actions often need different things to sit on to match.When people lie on the leisure chaise longue, can wish to have a footstool to loosen legs and feet; And after standing for a long time, people more wish to have a bergere to loosen the back.

But modern's living space is mostly compact, is difficult to enough spaces and places these things to sit on.So one can have chair concurrently several variations, to satisfy the different demand of user, become the main flow of modern thing to sit on design.

Summary of the invention

The present invention is directed to present seat and can't have concurrently and shelve legs and feet and support the different demands in back, problem that placing space is large, the present invention proposes a kind of having concurrently and shelve legs and feet and support back function, the dual-purpose thing to sit on of seat back of the body linkage type that placing space is little.

The dual-purpose thing to sit on of seat back of the body linkage type of the present invention, it is characterized in that: comprise bracing frame, the chair back, cushion, gear is installed in the side of described bracing frame, and the front installs and fixes the snap close of cushion; The periphery that the described chair back is trapped among described cushion forms the fence that does not seal, and installed inside first tooth bar of the described chair back; The bottom mounting spring of described cushion, the second tooth bar is installed in the side, and the tooth of described gear both sides is intermeshing with described the first tooth bar, described the second tooth bar respectively, forms rightabout two transmissions.

Described the first tooth bar and described the second tooth bar are parallel to each other.

Not be placed on the bracing frame by the cushion under the external pressure state, snap close supports the cushion bottom, and the upper surface of described cushion equates with the height of the described chair back to the distance on ground.

Described cushion arranges draw-in groove with the position that described snap close contacts.

Be not subjected to when cushion under the state of external pressure, the chair back contacts with ground, and the top of the chair back is concordant with cushion, and at this moment, the dual-purpose thing to sit on of seat back of the body linkage type can be used as footstool and uses; Outwards open snap close, and when cushion is subject to certain pressure, the spring contraction of cushion bottom, cushion sinks, the rack synchronous of cushion side sinks, drive the gear rotation of bracing frame side, the first tooth bar that drives chair back medial surface after the gear rotation moves in the opposite direction, namely moves upward, so that chair back built on stilts, this moment is practical as bergere, and this moment, snap close blocked the draw-in groove on the cushion, fixedly cushion; When opening the disappearance of snap close and pressure, recoil of spring, cushion rises, and the chair back descends, and comes back to the state of footstool.

The invention has the beneficial effects as follows: dual-use material, both can be used as footstool and used, can be used as again bergere and use, and the conversion operations between two states is simple, placing space is little.

The specific embodiment

Further specify the present invention below in conjunction with accompanying drawing

With reference to accompanying drawing:

The dual-purpose thing to sit on of seat back of the body linkage type of the present invention comprises bracing frame 1, the chair back 2, cushion 3, and gear 11 is installed in the side of described bracing frame 1, and the front installs and fixes the snap close 12 of cushion 3; The periphery that the described chair back 2 is trapped among described cushion 3 forms the fence that does not seal, and installed inside first tooth bar 21 of the described chair back 2; The bottom mounting spring 31 of described cushion 3, side are installed the second tooth bar 32, and the tooth of described gear 11 both sides is intermeshing with described the first tooth bar 21, described the second tooth bar 32 respectively, forms rightabout two transmissions.

Described the first tooth bar 21 is parallel to each other with described the second tooth bar 32.

Not be placed on the bracing frame 1 by the cushion 3 under the external pressure state, snap close 12 closures, the bottom of support seat cushion 3, the upper surface of described cushion 3 equates with the height of the described chair back 2 to the distance on ground.

Described cushion 3 arranges draw-in groove 31 with the position that described snap close 12 contacts.

When snap close 12 closures, cushion 3 is not subjected under the state of external pressure, and the chair back 2 contacts with ground, and the top of the chair back 2 is concordant with cushion 3, and at this moment, the dual-purpose thing to sit on of seat back of the body linkage type can be used as footstool and uses; 12 of snap close is opened, when cushion 3 was subject to certain pressure, the spring 31 of cushion 3 bottoms shrank, and cushion 3 sinks, the tooth bar 32 of cushion 3 sides sinks synchronously, drive gear 11 rotations of bracing frame 1 side, the first tooth bar 21 that drives the chair back 2 medial surfaces after gear 11 rotations moves in the opposite direction, namely moves upward, so that the chair back 2 built on stilts, simultaneously, snap close 12 blocks the draw-in groove 31 on the cushion 3, and this moment is practical as bergere; When snap close 12 is opened, when pressure disappears, spring 31 resiliences, cushion 3 rises, and the chair back 2 descends, and comes back to the state of footstool.

The described content of this specification embodiment only is enumerating the way of realization of inventive concept; protection scope of the present invention should not be regarded as only limiting to the concrete form that embodiment states, protection scope of the present invention also reaches in those skilled in the art conceives the equivalent technologies means that can expect according to the present invention.
