说明书全文 | The invention relates to the furniture sector, in particular but not exclusively to furniture used mainly as outdoor equipment, characterised by simple structures, made with materials having prolonged resistance to weathering and ageing. In particular, it refers to chairs, armchairs and sun loungers, which facilitate a short or longer period of rest for the user. More specifically, the invention relates to equipment for supporting a person at rest, comprising a rigid supporting frame, variously shaped, and a plurality of supporting elements, to support the weight of the person resting on said elements, advantageously secured to said frame. In the present description, the term support equipment is meant to indicate all those items of furniture, or parts of items of furniture, such as chairs, armchairs, their seats, sun loungers, springs for sun loungers, backrests, headrests and all those parts of items of furniture that support the weight of the person sitting, lying or resting thereon, making their use comfortable. Such support equipment is known from However, the critical point of these items of furniture lies not only in the preparation of the supporting elements, but also when it becomes necessary to replace elements that have broken or deteriorated through time and with use, i.e. during the steps of assembling and disassembling these elements on and from the supporting structure: in fact, the relevant operation is technically difficult and economically costly, so that often it is not worthwhile, even if the supporting structure, equipped with new elements, could still be used for a long time. All this being stated, the Applicant has found that the problems described can be overcome with a new type of equipment, provided with particular means for securing the supporting elements to the structure, that make the assembly and disassembly operations of said elements, on and from the structure, easy, fast and inexpensive and that provide a totally reliably product. Therefore, the object of the invention is support equipment for supporting a person at rest, which comprises a new system for securing the supporting element to the aforesaid frame. Therefore, the invention relates to support equipment for supporting a person at rest according to the subject-matter of claim 1. Further features and advantages of the invention will be more apparent from the detailed description of a particular, but not exclusive, embodiment of the equipment, provided purely to facilitate the description and understanding of the invention. This description will be set forth below with reference to said embodiment, conveniently represented by a chair, of which there are provided, purely for nonlimiting explanatory purposes, the accompanying drawings, wherein:
In at least one point of said slot, or of each portion of slot not connected with the adjacent portions, the slot is enlarged into a window 4 of considerably larger amplitude than the width of the slot. In a preferred embodiment of the invention ( According to the invention, the supporting structure comprises at least one strip 6, but preferably a plurality of strips 5 made of a suitable material, the ends of which are secured in said slots in axially opposite positions. These strips can be made of any suitable material, such as rubber or leather straps, but are preferably elastic strips made by weaving polyethylene fibres and synthetic rubber yarns. Preferably, the strips secured in opposite portions of tube are alternately crossed over with strips secured to adjacent portions of tube, as shown in Securing as above is performed as follows. At least one end flap 61, but preferably both end flaps, of each strip are folded over themselves ( There is inserted in the aforesaid eyelet a pin 7, preferably made of plastic material, having a central portion 71, with a width substantially the same as the width of the strip, and two expansions 72 at opposed ends, having at least a transverse dimension of greater amplitude than the transverse dimension present in the central portion of the pin, so as to block longitudinal sliding of the strip along the pin. The method of constraining the strips to the frame will be apparent. After having inserted a pin into an eyelet of the strip, an expansion of said pin is inserted in the tube through the window 4. The pin is made to slide longitudinally inside the tube, taking care that the strip is housed inside the slot, so as also to insert the expansion at the opposite end of the pin inside the tube. In this way, the weight of the person resting or sitting or lying on the equipment can only put the strip under tensile stress but cannot cause its removal from the tube as the expansions of the pin, through interference, retain the loop of the strip wrapped around the pin inside the tube. Preferably, a large number of strips are used, each wrapped at both ends around a corresponding pin. Assembly of the strips on the equipment is performed by inserting the various pins in succession through the window 4 inside the tube, making them slide along said tube to make room for the subsequent insertion. It can be immediately observed how the length of the central portion 71 of the pin controls the width of the strip 6 the length of the expansions 72 controls the distance between adjacent strips and the total length of the pin 7, together with any flexibility of the material of which it is formed, controls the radius of curvature of the arc C-D ( It must be noted that the length of the lateral expansions of the pin is not necessarily identical for both the expansions; for example, at least one pin can have a lateral expansion of different length from that of the expansion at the opposite end. With reference to the prototype produced by the Applicant, the frame is constructed with extruded aluminium tubular elements ( The material of the frame is preferable selected in the group comprising aluminium, that of the pin is preferably selected in the group comprising PE, HDPE, nylon, ABS, PP (polymers in general) while the textile material of the elastic strips is preferably selected in the group comprising suitable treated natural fibres, such as cotton, flax, hemp, etc, or synthetic fibres, such as polyethylene, acrylic fibre or textilene. The invention solves the problem stated and obtains various advantages. In fact, the production of the supporting strips and of the securing pins is advantageously inexpensive and, at the same time, assembly of the strips on the supporting structure is also fast, inexpensive and easy to perform, as is disassembly of the strips no longer usable or of the related securing pins. In the present description, all the possible structural and dimensional alternatives to the embodiments of the invention specifically described have not as a rule been illustrated: in fact, it seemed unnecessary to expand the construction details of the system of the invention as, after the instructions provided herein, no person skilled in the art will have difficulty in designing, choosing the appropriate materials and sizes, the most advantageous technical solution. However, these variants are all intended to fall within the scope of protection of the present patent, as these alternative embodiments are easily attainable from the description provided herein of the relation that links each embodiment with the result that the invention aims to achieve. |
