Description
Technical field
The seat that the utility model relates to take for people, in particular to a kind of folding seat.
Background technique
Seat (seat when especially baby child feeds) is widely used among daily life, in normal use situation
Under, seat needs to occupy biggish spatial position, and for the ease of the storage and transport of seat, some seats are set as superposed type
Structure reduces the needs of space hold by stacking for multiple seats, and other seats then use accordion structure, pass through
By the parts thereof rotation on seat and with other components mutually close to and reduce volume.
Due to needing to avoid interfering and stopping for different components, the structure of tilting seat is generally all more simple
It is single, it usually only include the seat of support human buttock and the chair leg of support seat, this kind of seat is due to lacking backrest and handrail
Cause its comfort level poor；There are also the tilting seats for being provided with backrest or handrail, but backrest can not effectively be rolled over
It is folded, and handrail is then generally only one piece of hinged plate in one end, either structural strength or comfort is all lower.
Utility model content
The main purpose of the utility model is to propose a kind of folding volume is small and structural strength is high rumble seat, to improve
The convenience of comfort and storage, transport.
To achieve the above object, the utility model proposes a kind of rumble seats, including seat, chair leg, backrest and handrail, separately
There is the strut for supporting armrests；One end of chair leg is articulated with the bottom of seat, and the bottom of backrest is articulated with the rear portion of seat, support
The lower end of bar is articulated with the side in the middle part of seat, and upper end of the both ends of handrail respectively with the middle part of backrest and strut is hinged, chair
Seat in the hinged place of the hinged place of backrest, the hinged place of backrest and handrail, handrail and strut or the hinged place of strut and seat
Any one be provided with the link lever locking devices that two parts that are hinged are fixed.
Technical solutions of the utility model, chair leg are rotated when in use with the hinged place of itself and seat bottom, when
It is rotated backward when being folded to seat bottom；In addition, mutually being cut with scissors two-by-two between seat and backrest, handrail and strut
It connects, constitutes the link mechanism of quadrangle, four angles of the quadrangle are the hinge joint between adjacent components, in these hinges
Locking device is set either one or two of among contact, the two of them side of quadrangle is fixed to each other positioning by locking device, i.e.,
Entire quadrangle can be fixed on setting state, so that it is fixed on backrest, handrail and strut all on seat with particular state, shape
At the seat taken under general state for people；And when needing to fold seat, unlock device, will be hinged with seat
Backrest and strut turn to and seat is close to handrail is also just close on seat simultaneously, is similar to four of parallelogram
While being deformed into straight line section around four angle rotations.The rumble seat passes through the company between backrest, handrail and strut and seat
Relationship is connect, both made rumble seat that backrest and handrail are smoothly set, the comfort used is greatly improved, further through strut
The structural strength for improving handrail and entire seat is set, while also making the compact-sized of the seat, folded state lower
There are minimum space hold needs, greatly improves the convenience of storage and transport.
