Definitions

  • the invention is comprised in the field of chairs designed for their use in places such as auditoriums, cinemas, theaters, etc.
  • chairs of this type can be provided with means which allow tilting the back when a force is exerted thereon (for example, by means of the user's back) and which make the back recover its original (normally more vertical) position when this force is no longer exerted.
  • These means usually comprise metallic springs.
  • a drawback with this type of element is that it tends to generate noise, a great drawback especially when the chair is intended for a cinema, for a theater, etc.
  • a first aspect of the invention relates to a side module for a chair, comprising a side element, for example, made of plastic or the like, formed by a molded single body or by several molded parts attached to one another in a conventional manner;
  • WO-A-03/007758 and WO-A-2004/095985 reflect some known structures which could be useful as a base for the structure of the side element of the invention.
  • the side element can comprise a base part intended to be secured to the floor of an establishment, for example, by means of screws or bolts or by means of other fixing elements, and an upper part attached to said base part, for example, forming part of one and the same molded general body; types without the base part, for example, can also be contemplated in the case of seats which are directly fastened on steps of a room or on other support structures; furthermore, the side element can comprise an armrest, for example, an armrest attached in a tilting or hinged manner with respect to the rest of the side element.
  • the side module additionally comprises at least one support element attached to a side of the side element, said support element being provided with attachment means for attaching (for example, by means of screws) a seat and a back to the support element.
  • the support element is attached or fixed (for example, by means of a screw traversing a front part of the support element and which can pass through a bushing, through one or more washers, etc.) to the side of the side element (for example, to an upper part of the side element) such as to pivot between a first position corresponding to a non-reclined position of the back and a second position corresponding to a reclined position of the back (normally less vertical than the non-reclined position).
  • the support element is provided with a through hole through which a first fixing device or element (for example, the screw mentioned above) attached to said side of the side element extends.
  • a first fixing device or element for example, the screw mentioned above
  • a second fixing device or element attached to the support element.
  • the fixing elements can be independent elements (for example, screws, bolts or the like, as has been suggested above) fixed to the side of the side element and to the support element, or they can be integrally formed with the side element and with the support element, respectively.
  • the fixing elements can additionally comprise bushings, washers and/or other complementary elements conventionally used in this type of application.
  • the side module additionally comprises a non-metallic elastic element (for example, made of rubber or the like) attached to said fixing elements.
  • This elastic element is assembled so that it attracts the support element towards it first position and so that the support element can be pivoted towards its second position against a force exerted by said elastic element.
  • a non-metallic elastic element for example, made of rubber or the like, reduces the risk of annoying noise generated during the use of the chair. Furthermore, with the claimed arrangement, the elastic element can be easily replaced in the event that it breaks or when it starts to deteriorate. Furthermore, the possibility can be provided of offering different types of elastic elements, for example, with different elongation or elasticity characteristics, so that, for example, a chair buyer can decide the degree of hardness of the reclining mechanism and, therefore, the force necessary to tilt the back. This facilitates adapting the basic structure to the needs or wishes of the user.
  • the through hole can have larger dimensions that the first fixing element (i.e., the first fixing element can pass "very easily” through the through hole) and can be configured so that the first position and the second position of the support element are determined by means of respective points of contact or "stop” between an inner surface or edge of the through hole and the first fixing element.
  • the first fixing element is thus also useful to limit the pivoting of the back, so that it does not pass beyond said first and second position, respectively.
  • the central hole can have an oval or rectangular elongated shape and the points of contact or "stop” can correspond to the "shorter sides" of the rectangle. In such case, the pivoting or tilting angle is determined by the length of the rectangle, or by the larger diameter of the oval.
  • Other configurations are possible, for example, a curved elongated configuration, the width of which is adjusted to the dimensions of the first fixing element and the length of which corresponds to the pivoting angle.
  • the first fixing element can be provided with a stop element (for example, a washer) adjoined at least partially on a face of the support element farthest from the side element in correspondence with the through hole, so that it prevents the support element from separating from the side element in correspondence with the through hole.
  • the first fixing element thus establishes a second point of "anchoring" between the support element and the side element.
  • the support element can have, on the face farthest from the side element, a recessed area in correspondence with the through hole, said second fixing element being located in said recessed area and said elastic element extending between said first fixing element and said second fixing element, in said recessed area.
  • the fixing elements and the elastic element may or may not project with respect to the inner face of the support element, i.e., with respect to the face farthest from the side element.
  • the recessed area can have two broader sub-areas connected by a narrower sub-area, the elastic element extending through said narrower sub-area.
  • the narrower sub-area it is convenient for the narrower sub-area to be broader than the elastic element in its passage through said narrower sub-area to facilitate the pivoting.
  • the elastic element can comprise an elongated element made of elastic material configured to exert an attractive force between the first fixing element and the second fixing element, at least when the support element is not in the first position.
  • the elastic element can have two thicker or wider ends (in the plane of the face of the support element) connected by a less thick or wide (i.e., narrower) elongated central part, a first one of said ends being traversed by at least one part of the first fixing element, and a second one of said ends being traversed by at least one part of said second fixing element.
  • the configuration of the narrower part of the elastic element substantially determines the force that it will exert on the fixing elements.
  • the first fixing element and/or the second fixing element can comprise a screw (and, for example, additional element such as a bushing traversed by the screw, etc.), the elastic element being traversed by at least said screw or screws.
  • the side module can comprise two substantially identical support elements assembled in a substantially identical way, one on each side of the side element, so that the side module is suitable for forming an (inner) part of a row of chairs, i.e., for being shared by two chairs.
  • the attachment means for attaching a seat to the support element can include a bent plate (for example, with through holes which allow supporting a non-folding seat on said bent plate and then screwing the seat to the bent plate by means of screws passing through said through holes) or a "ball joint" element which can comprise a groove for receiving a pivot shaft of a folding seat.
  • Another aspect of the invention relates to a chair comprising two side modules according to what has been described above, with their respective support elements, and a seat and a back attached to said support elements.
  • the side module according to the invention can, according to a preferred embodiment of the invention, comprise a side element 1 which can have a conventional general configuration, for example, with a base part 11 with holes (not shown in Figures 1 and 2 ) to be attached to the floor, for example, by means of bolts, screws or the like.
  • An upper part 12 is attached to the base part 11 by means of a narrower transition section, which upper part has two substantially planar faces, although it can have holes, reinforcement ribs, etc.
  • An elevational view of the side element 1 can be observed in Figure 7 .
  • a fixed or lowerable armrest 13 configured in any suitable manner can be coupled to the upper part.
  • This support element 2 which is shown in a perspective view in Figure 8 , has fixing means 21 (in the form of threaded rods) for fixing a back to the support element at one side of the back, and fixing means 22 (which can include a type of bent plate with through holes, screwed to the support element 2) for fixing a seat to the support element on one side of the seat.
  • the support element 2 has a substantially planar general configuration and a bent general shape, with a part extending in correspondence with the seat and with another part extending substantially parallel to the extension of the back.
  • the support element 2 can be partially hollow and provided with reinforcement ribs, etc., in a conventional way.
  • the support element 2 has a recessed area 24 in the face farthest from the side element 1.
  • This recessed area has two broader sub-areas 24A, 24B connected by a narrower sub-area 24C (see Figure 3 ).
  • a through hole 23 through which a fixing element 100 attached to the upper part 12 of the side element 1 extends (and which therefore traverses the support element through the through hole).
  • Another fixing element is located in the other broader sub-area 24B.
  • the assembly comprises an elastic element made of rubber, with two broader or thicker ends 5A and 5B, traversed by the respective fixing elements 100 and 200, so that one of said thicker ends 5A is attached to the upper part 11 of the side element 1 (through the through hole), and so that the other thicker end 5B is attached to the support element 2, in the recessed area 24.
  • the two thicker ends 5A and 5B are connected by a narrower central section 5C, with dimensions chosen according to the characteristics of the rubber and the desired "elasticity".
  • a washer 101 has been provided in correspondence with the first fixing element 100, which prevents the support element from separating from the side element in the area of the through hole.
  • the substantially rectangular configuration and the dimensions of the through hole 23 are such that the support element 2 can tilt between the mentioned first position ( Figure 1 ) and second position ( Figure 2 ), the end positions being defined by respective positions of contact or stop between the first fixing element 100 and the inner surface of the through hole 23, specifically, in correspondence with the shorter sides of the rectangle.
  • the elastic element exerts an attractive force which pulls said support element 2 towards its first position, i.e., towards the "non-reclined" position illustrated in Figure 1 .
  • This force depends on the characteristics of the material and on the dimensions of the elastic element, therefore it is easy to modify the "reclining resistance" characteristics of a chair, replacing one elastic element with another one having different characteristics.
  • Figure 4 schematically illustrates how each of the first fixing element 100 and the second fixing element 200 comprises a screw 300, 310 traversing a bushing 301 and 311.
  • Figure 4A schematically illustrates how the second fixing element 200 comprises a screw 300 traversing a washer 302 and a bushing 301, and with an end screwed into a nut 303 located in a corresponding recess in the opposite face of the support element 2.
  • Figure 4B illustrates how the first fixing element comprises a screw 310 traversing a washer 312 to be screwed into a metallic socket 313 with an inner thread, traversing a bushing 311 and another washer 101.
  • This metallic socket 313 is located in the side element 1 and further traverses the bushing 311, the washer 101 and the end 5A of the elastic element, one end being supported against the washer 312, as can be seen in Figure 4B .
  • Figure 5 schematically illustrates a side module in which two support elements are attached to the side element.
  • Figure 9 shows an alternative embodiment, useful for chairs with a folding seat.
  • the structure instead of the bent plate 22 with through holes of the embodiment illustrated in Figure 1 (which can correspond to an embodiment with a non-folding seat, i.e., with the seat fixedly attached to the bent plate 22), the structure incorporates a ball joint 22A screwed to the support element 2, as illustrated in Figure 9 .
  • the seat can thus be coupled in said ball joint so that it can pivot about a shaft housed in a groove 22B in the ball joint, whereby the seat can be folded.
  • Figure 10 shows a possible embodiment of the ball joint 22A with the groove 22B in which the pivot shaft of the folding seat will be located, and a strip 22C which serves to retain said shaft in the groove.
  • Figure 6 shows a row of seats, with their backs 4 and seats 3 screwed to the support elements (not shown in the figure).
  • the invention is not limited to the specific embodiments which have been described but rather it also covers, for example, the variants which may be carried out by a person skilled in the art (for example, in relation to the choice of materials, dimensions, components, configuration, etc.), within what is deduced from the claims.
