In the embodiment as shown, erecting device 8a, b are the most attached with respect to the central shaft of seat part 4 Receiving framework, therefore fulcrum joint will be located in the usual side with the backrest placement towards chaise longue of parallel leg and back Between knee and the buttocks of the user that formula is taken a seat.Erecting device can be arranged in distance seat as an example towards backrest The distance of leading edge 1/3.It is intended that erecting device 8 to arrange in its this mode performing self-balancing inclination.Owing to this inclines Tiltedly by installing mechanism and combine its layout of balancing spring 14 and limit, therefore erecting device be preferably not provided with locking piece or Scalable brake component.But, chaise longue can be provided with the final retainer of certain swing limiting seat part.

Chaise longue is provided with balancing spring 14.In the accompanying drawing illustrated, balancing spring is arranged in below under(-)chassis and backrest Between sofa frame.But, balancing spring 14 can be along the side panel layout of sofa frame 2 rather than the sand below backrest Send out in frame facet.Structure is freely arranged spring assembly according to the technical staff of the alignment equipment of the present invention, there its It is best suitable for obtaining the desired balance in seat part and the sufficient resistance of opposing inclination, in order to make seat part Tilting is comfortable for the user.The most flat disc spring, leaf spring, rubber band device or layout, torsion spring can also be used Deng the spring assembly of other kind.Substituting the end that these are arranged in whippletree, spring can be relative to seat part and the end Rotatable erecting device between portion's framework is arranged.

Shutter member (shutter) or renovate (flap) 16 and be hinged on pin joint 17a, in b at the leading edge of seat part. Renovate also in rotatable installation site 18a, b is rotatably attached to sofa frame 2 in the opposite end being attached to seat part. When seat part 4 tilts along a direction, renovating 16 will tilt and thus shape with opposite to that state (phase) Become " bending " in seat plane or surface or fracture and the knee district once taken a seat in the chaise longue being provided with alignment equipment Rising in territory.This will increase the seat sense comfort level of the user being sitting in chaise longue.If user selects to lie down or not Only a people is sitting on chaise longue, and seat part will tilt in passive position to returning, therefore formed be suitable to accommodate a people lie down, More people take a seat and are partly hung in the straight continuous sitting face of the people on sofa.

Fig. 2 shows the chaise longue that seat part 4 is in the second position, and wherein seat part is downward-sloping towards backrest 3. When seat part tilts, downward-sloping near the cross bar 9 of backrest 3, and be inclined upwardly near the whippletree 9 renovating 16.Turn over Lid 16 is thus inclined upwardly near seat part 4, and will be around rotatable mountings 18a, and b rotates so that renovate 16 with Seat part 4 relative to each other forms the angle more than 0 °.

Compared with for other known arrangement of chaise longue or bench, the difference of the solution of the present invention is seat and renovates hinge It is connected at remote point, and has and make seat and renovate the additional pin joint 17 linked together.This layout allows for launching To allow seat relative to each other to bend with renovating.Here, this is by using longitudinally expansible pin joint 17 to obtain.Real first Executing in mode, this is hinged can be traditional, have common have two for the socket piece that is connected to framework to part (to-part) hinge.This hinge can be strongly attached to framework at first end and allow the other end at the pipe of framework simultaneously Son is internal freely to slide.Can also allow for two ends freely to slide at tube interior.Thus, in pin joint, work as seat When position is inclined upwardly, framework will separate to a certain extent.

Preferably, the elasticity that pin joint is embodied as shown in Fig. 3 a and figure b is connected.This by tubular form sleeve pipe or The socket piece 19 of elastic polymer material is made.Socket piece is cone towards two ends and is provided with cervical region in core Or axle ring 20.Socket piece preferably completely or partly in the centre of pipe seals with wall 21.In order to form joint, socket Part 19 slides in each tube end of two elements so that rotatably with the first pipe end more or less The mode covering an end of socket piece and the second end of second pipe end covering socket piece connects.

Owing to socket piece is only that in the tube end sliding into framework, therefore this connection is installed easily.It is with a discrete item Make and the most wear-resisting.Additionally, it will not send creak sound when deployed.The design of socket also allows for pipe end necessarily Longitudinally slide relative to socket piece in degree, to eliminate the tension force in framework constructs or stress riser.

Although the embodiment illustrated is hollow, it is also possible to manufacturing bulk socket piece, formation is had circle by it there Tapered end portion and the rounded longitudinal element of the axle ring in mid portion.But, owing to span centre is empty and bulk adapter piece cross section Different stress distribution, hollow design may be provided for adding in addition to the probability of motility the biggest in the design of element Strong element.Partition wall in the mid portion of socket piece can provide the further reinforcement of this element, thus provides durable Property and intensity.
