Abstract
Description
- The object of the present invention is a sitting apparatus, such as a chair, an armchair, a deckchair, a rocking chair, a sofa and the like, suitable for the sitting of a user.
- In particular, the object of the present invention is a sitting apparatus of the type comprising a frame and a sheet, suitable stretched and associated to the frame for forming a portion of seat, suitable for supporting a sitting user, and/or a support portion, such as a back, suitable for supporting a sitting user resting thereon.
- In the reference field, the need of effectively stretching the sheet and associating it to the frame, keeping it stretched, is strongly felt, for forming the desired sitting apparatus.
- A known method, for example for making rocking chairs, provides for associating a first edge of the sheet to a first rod of the frame, suitably pulling a second edge, opposite the first one, for stretching the sheet, and associating the second edge to a second rod of the frame.
- As it can be understood, said method is difficult to effect and such as to considerably slow down the rocking chair manufacturing process and most of the times, such as to need the manual intervention of dedicated workers.
- A further method, for example used for making deckchairs, provides for providing an intermediate rod of the frame with a plurality of springs, attaching the unstretched sheet to two end rods of the frame, and then stretching the sheet coupling it, generally at its centre line, to said springs.
- Such method exhibits the disadvantage of having to provide for suitable springs coupled to the frame, of having to provide for a sheet provided with a coupling portion to which the springs must be associated. Very often, moreover, the springs used, of a small size, are subject to breakage, and the additional portion of the sheet, to which the springs are connected, is subject to breakage and tearing.
- The object of the present invention is to make a sitting apparatus comprising a frame and a sheet which should overcome the disadvantages mentioned with reference to the prior art while meeting the above requirements.
- Such object is achieved by a sitting apparatus in accordance with claim 1. The dependent claims describe further embodiments.
- The features and advantages of the sitting apparatus according to the present invention will appear more clearly from the following description, made with reference to the annexed figures, wherein:
- - figure 1 shows a perspective view of a frame of a sitting apparatus comprising a frame and a sheet, in a closed configuration;
- - figure 2 shows the frame of figure 1, in an open configuration; and
- - figures 3a to 3b show a sequence of passage of the frame of figures 1 and 2 from the closed configuration to the open configuration.
- For clarity of explanation, in the following description reference is made to a rocking chair. It is understood, however, that the described invention can be applied to a general sitting apparatus, such as a chair, an armchair, a deckchair and more.

- The upper longitudinal edge of the sheet is connected to the upper
longitudinal rod 20 of the frame portion for resting 4. For example, said edge is threaded on said rod. - In a closed configuration of the frame (figure 1), wherein the frame portion for resting is at least partly overlapped to the frame portion for sitting, the sheet, from the outer longitudinal edge towards the upper longitudinal edge, is connected by its outer longitudinal edge to the outer longitudinal rod 6 of the frame portion for sitting, and partly winds about the inner longitudinal rod 8, so as to go beyond the quadrangular structure of the frame portion for sitting.
- Moreover, the sheet partly winds about the lower
longitudinal rod 22 and is connected by its upper longitudinal edge to the upperlongitudinal rod 20 of the frame portion for resting, so as to go out of the quadrangular structure of the frame portion for resting. - In said closed configuration, it is possible to see a sheet portion between the outer longitudinal rod 6 and the inner longitudinal rod 8, called sheet portion for sitting 31; a sheet portion between the inner longitudinal rod 8 and the lower
longitudinal rod 22, calledactive portion 32; a sheet portion between the innerlongitudinal rod 22 and the upperlongitudinal rod 20, called sheet portion for resting 34. - In an open configuration, said frame portion for resting exhibits a rotated arrangement relative to the arrangement taken in said closed configuration.
