Description

Chair.

The present invention relates to a chair.

Currently they are used types of chairs that they are usually constituted by a support mount for a seat that is optionally provided with a backrest and / or armrest

The saddle and seat are preferably interconnected when riveting or screwing or through interconnection of screws that cross the seat to be associated in holes with a complementary shape formed in the mount.

However, such types of known chairs, they have the disadvantage that they require the use of riveting machines or at least specialized personnel for carry out the assembly and interconnection of the pieces by means of the previously known types of mechanical means.

Consequently, these assembly operations are perform directly during production, so that the product final is the complete chair ready to use.

This known type of chair, directly pre-assembled at the factory, has the disadvantage of being very bulky, thereby causing operations to store and transport it difficult and heavy.

As a partial remedy, chairs are known which are provided so that they can be stacked together, thus allowing a considerable reduction of space.

However, this constructive solution has the inconvenience of causing a considerable limitation of creative possibilities of the engineer and the designer, since the aesthetic appearance of the chair is subordinated to the need for be stackable; In addition, the dimensions are still maintained signifiers

The object of the present invention is to solve the technical problems mentioned above, removed the drawbacks of the cited prior art, by providing a chair that allows quick and easy interconnection between the seat and the mount that does not require the availability of any type of machine.

Within this objective, an object of the invention is to provide a chair that allows optimal storage and transport from the point of production to the point of distribution or sale

Another object is to reduce production costs of said chairs by reducing both the number of machines used as of the use of labor.

Another object is to provide a chair that allows the adjustment of the mutual position of the saddle and the seat, ensuring that the user can adjust the chair to his liking.

Another object is to provide a chair that results structurally simple and has manufacturing costs low.

This goal and these and other objects that will be more evident from now on are achieved by a chair according to claim 1 attached.

Advantageously, there are additional means for lock said seat in a chosen position with respect to said mount.

Conveniently, there are means of limiting race to position said seat with respect to said mount.

Other features and advantages of the invention will be more evident from the following description detailed of a particular embodiment thereof, illustrated to non-limiting example mode in the accompanying drawings, in which:

Figure 1 is a view from under the chair according to the invention;

Figure 2 is a partially front view sectioned from the chair of figure 1;

Figure 3 is a perspective view from exploded down the chair;

Figures 4 and 5 are perspective views of two details of figure 3;

Figure 6 is a perspective view of a second embodiment of the saddle mount.

In reference to the figures, the reference numeral 1 designates a chair comprising a saddle, designated by reference number 2, which is advantageously made of a metallic material that is advantageously tubular and has, in this realization, four legs 3 protruding down.

Advantageously, the legs are mutually associated or rigidly coupled by two transverse elements 4a and by two longitudinal elements, designated by the reference numeric 4b, which constitute a quadrilateral that is arranged in an approximately horizontal plane.

Mount 2 acts as a support for a seat, designated by reference number 5, with which it is optionally associated with a backrest 6 and / or two armrests not shown in the figure.

Two approximately rectangular fins 7 protrude externally from the pair of longitudinal elements 4b of the mount 2 and constitute means to slide the coupling towards the complementary shaped media formed below said seat 5.

The media with complementary form are advantageously constituted by a pair of receptacles 8 formed through the spaces between the bottom surface of seat 5 and two tabs 9 protruding from it so that they are placed approximately in parallel with seat 5.

The tabs 9 are associated, or obtained from one piece, with the seat on at least one edge, designated by the numerical reference 10a.

In the example shown in the figures, the tabs 9 have a first edge 10a and a second edge 10b, which they are contiguous and provide a connection to seat 5, so that the second edge 10b constitutes career limitation means for the sliding of the pair of fins 7 in the respective seats 8.

The pair of fins 7 has advantageously first holes, designated by numerical reference 11, which are preferably threaded for optional interconnection of screws, not shown, running through slots 12a or second holes 12b formed in the tabs 9.

Advantageously, there are also suitable means for facilitate sliding in only one direction, such as by for example, the pins 13 that protrude inclined from the lower surfaces of the two fins 7 and may be optionally associated within said second holes 12b.

With reference to figure 3, note that it is possible to fit the seat in the saddle easily and very quickly: this assembly does not require knowledge or skills specials and therefore can optionally be performed even by the user

This allows to send the chairs in a condition disassembled, so that they occupy a very small space to be constituted by a saddle and a seat (with or without backrest) that they can be stacked separately on other mounts and seating.

The sliding and interlocking connection allows also save on the cost of the mechanical means used usually, avoiding in particular the use of screws and rivets

Even so, it is possible to use for example screws for connecting the fins 7 of the mount to the tabs 9.

In this way it has been observed that the chair of the invention has achieved the objective and intended objects, a chair which has been provided that allows interconnection once the components have been transported to the points of distribution or sale

In this way one not only reduces costs Production but also storage and shipping costs.

Figure 6 illustrates a different embodiment of the invention, in which reference numeral 101 designates a chair comprising a mount 102 appropriate to act as a support for a seat, designated by reference number 105, with which are optionally associated with a backrest 106 and / or two armrest, not shown in the figure.

The mount 102 is advantageously constituted by a plate 120, which is approximately rectangular and is provided with interconnection means 121 for one or more legs of ground support, which are not shown.

Interconnection means 121 are constituted, for example, by a hole that is appropriate for the interconnection for example with a plug, not shown, which is at in turn associated in a lower area with said one or more legs.

Plate 120 is provided laterally with two longitudinal edges, designated by numerical reference 104b, of which two approximately rectangular fins protrude 107 to constitute the means for sliding the coupling towards the complementary shaped means formed under the seat 105.

The media with complementary form are advantageously constituted by two receptacles 108 formed by the spaces provided between the bottom surface of the seat 105 and two tabs 109 protruding from the seat so that it placed approximately parallel to seat 105.

This embodiment achieves the same advantages as the previous one.

The materials used, as well as the dimensions that constitute the individual components of the chair of the invention, they may be naturally more relevant according With the specific needs.

Where the technical characteristics mentioned in any claim are followed with signs of reference, those reference signs have been included only with the purpose of increasing the readability of the claims and consequently, such reference signs have no effect of limitation in the interpretation of each of the elements identified in the example by said reference signs.
