Description
Technical field
The present invention relates to medical instruments, more specifically, it relates to a kind of pull-alongs chaise longue.
Background technique
Chaise longue is the chair for lying down, and is a kind of essential medical instruments in dental care field, and is wherein folded
Chaise longue is the most commonly used.
Folding deck chair is a kind of using joint motion principle progress foldover design, can fold receipts by various folding modes
The chaise longue put.It is convenient and practical, and storage is convenient.Folding deck chair is by seat frame, back frame, front foot frame with rear foot frame
Frame, arm rest cross bar are constituted, and the rotation of Folding deck chair back frame is actively socketed on behind seat frame, and arm rest cross bar both ends are fixed on seat
On frame, front foot frame ends are rotatably connected on seat frame, and braced frame is equipped between rear foot frame and preceding foot frame,
The end of braced frame is rotatably connected under seat frame.
Folding deck chair possesses many places rotating joint compared with common chaise longue, has volume after folding inner wrapping readily excellent
Point, but its back frame and preceding foot frame need individually to adjust, and can not link, when adjusting, need repeatedly front and back adjustment, step
It is cumbersome.
Summary of the invention
It needs individually to adjust for existing Folding deck chair back frame and preceding foot frame, the technical issues of can not linking, this
Invention provides a kind of pull-alongs chaise longue, has the advantages that its back frame and preceding foot frame linkage are adjusted.
To achieve the above object, the present invention provides the following technical scheme that
A kind of pull-alongs chaise longue, be rotatably connected on including base support and respectively the back-supporteds of the base support two sides with
Thigh support, there are two support leg, the back-supported, the thigh support and the branch for the base support rotation connection
The rotational axis line of support foot is parallel, is hinged with first between the support leg and the back-supported of the back-supported
Elastic telescopic part；
The base support sliding is connected with leg strut, and one end of the leg strut abuts the thigh support, another
The second elastic telescopic part is hinged between end and the first elastic telescopic part.
Through the above technical solutions, back-supported and thigh support are rotated in the two sides of base support, the first elastic telescopic
Resistance when part can allow back-supported to rotate constantly changes to adapt to the posture of people, and back-supported drives the first elastic telescopic part to turn
Dynamic, elasticity connection is realized in the transmission between the first elastic telescopic part and thigh support by the second elastic telescopic part and leg strut
Dynamic, when being laid flat back-supported, thigh support can decline automatically, and when holding up back-supported, thigh support can rise automatically, and second
Resistance when elastic telescopic part can allow thigh support to rotate also constantly changes to adapt to the posture of people.
Further, the base support is fixedly connected with position-limiting tube, and the leg strut slides in the position-limiting tube,
And the position-limiting tube is stretched out at both ends, one end of the leg strut is abutted with the thigh support, the other end and described the
Two elastic telescopic parts are hinged.
Through the above technical solutions, leg strut is driven between the second elastic telescopic part and thigh support, position-limiting tube is then
The zone of action for limiting leg strut, enables its transmission effect to stablize performance.
Further, the position-limiting tube is long tube, and internal diameter is equal to the maximum outside diameter size of the thigh support.
Through the above technical solutions, leg strut realizes the second elasticity with regard between part and thigh support in sliding in position-limiting tube
Linkage.
Further, the position-limiting tube is annulus, and its internal diameter is greater than the maximum outside diameter size of the leg strut.
Through the above technical solutions, leg strut can be limited in certain area coverage by circular position-limiting tube, allow
Leg strut changes its posture in the regional scope, and it is cleverer to realize that the linkage between back rest supports and thigh support is adjusted
It is living.
Further, the base support and the support leg are rotatablely connected by angle demodulator.
Through the above technical solutions, angle demodulator can change angle of the support leg on base support, and it is able to maintain
The angle is constant, conducive to the posture for keeping chaise longue.
Further, one end of the leg strut abuts the thigh support, and slides and connect with the thigh support,
The glide direction of the leg strut is vertical with the rotational axis line of the thigh support.
Through the above technical solutions, the first elastic telescopic part is driven, the first elastic telescopic part band after back-supported rotation
Dynamic second elastic telescopic part, the second elastic telescopic part drive leg strut to slide in thigh support, finally change thigh support
Posture.
Further, the back-supported is fixedly connected with the support frame protruded between the support leg, and support frame as described above turns
It is dynamic to be connected with multiple idler wheels.
Through the above technical solutions, drive support frame rotation to change the position of idler wheel after back-supported rotation, rolling is allowed
Wheel can contact ground, to reduce the frictional force between chaise longue and ground, facilitate dragging chaise longue.
Further, support frame as described above is fixedly connected with the apical grafting bar for abutting the thigh support.
Through the above technical solutions, apical grafting bar can limit the extreme lower position of thigh support, thigh support is avoided to be forced outside
Ground posture is too low.
Compared with prior art, the beneficial effects of the present invention are: unlock angle demodulator, back-supported pass through the first elasticity
Extensible member drives support leg, passes through the biography of the second elastic telescopic part and leg strut between the first elastic telescopic part and thigh support
It moves and realizes elasticity linkage, when being laid flat back-supported, thigh support can decline automatically, and when holding up back-supported, thigh support can be certainly
Dynamic to rise, back-supported drives the rotation of the first elastic telescopic part, resistance when the first elastic telescopic part can allow back-supported to rotate
To adapt to the posture of people, the first elastic telescopic part drives the second elastic telescopic part for constantly variation, and the second elastic telescopic part can allow leg
Resistance when portion's support rotating also constantly changes to adapt to the posture of people.
