Definitions
- the invention relates to a process for the manufacture of armchair frames for cinemas, theaters and / or the like based on a small number of molded plastic parts, which allows to obtain variable aesthetic seats and support feet suitable for the desired height for the armchair and the inclined plane of the room in which they are to be located.
- the frame obtained by the process described in this invention in addition to being cheaper to manufacture than the traditional metal ones, is extremely simple to assemble, has less weight and what is also very important, receives the injection of the metal frames polyurethane dough in which it should be embedded.
- the seats for cinemas, theaters and the like are made up of two metal frames constituting the seat and the backrest, of adequate dimensions and configuration to those of the armchair to be obtained.
- Said metal frames are in turn constituted from a metal frame to which they find welded a plurality of rods as springs.
- the metal frames thus constituted are introduced and positioned in a mold and on them a mass of polyurethane is injected which, when cooled, adopts the shape of the mold that logically corresponds to that of the backrest and / or seat. Obviously, the metal frame is embedded in the polyurethane mass.
- the next operation consists of upholstering molded parts, that is, seat and backrest.
- the constituent parts of the seat and the backrest, once upholstered, are mounted, articulated to each other, to which at the same time the support legs and anchoring shoes of the armchair are attached to the floor.
- the assembly that integrates the sides, legs and anchoring shoes, normally, as indicated above, is made up of independent pieces welded or screwed together.
- the process object of the invention allows to obtain frames for cinema seats, theaters and the like from a small number of pieces, since it eliminates the classic metal frames and replaces them with plastic pieces that can have variable dimensions and configuration. Likewise, the expensive and complicated sides, legs and metal shoes are eliminated, since they are obtained integrated in a single piece of plastic, of variable configuration.
- the plastic parts that constitute the backrests and seats have a resistant frame or structure, transverse bands or slats, as springs that, at the same time, allow the passage of polyurethane foam from one part to the other of the piece , when injected on them.
- the plastic frame object of the invention is constituted by the combination of the following parts:
- a fundamental characteristic of the process object of the invention refers to the fact that in order to obtain the basic parts of the frame, that is to say, sides and backrests, one starts from a mold that has a fixed part, in which the invariable part of the piece, and an interchangeable complementary part, in which the different aesthetic variations are formed. In this way, keeping in common the most voluminous part of the mold, it is possible to obtain variable configurations in these parts, seat back and sides.
- the fixed part of the mold corresponds to the body of the side that is common to all of them, while the leg and the shoe will be obtained according to the configuration of the part interchangeable mold.
- backups with different lengths and / or configurations can be achieved with a single mold, that is, without having to have a different mold for each different type of backrest, thus greatly reducing the cost of obtaining the backups.
- the lower part of the backrests which is common to all of them, will correspond to the fixed part of the mold while the upper part will have a variable configuration according to the interchangeable part of mold used.
- the seats these usually present a configuration common to all the seats but, if it were necessary to obtain seats with various aesthetic configurations, a mold with a fixed part and another interchangeable could be used, as for backrests and sides. .
- all the constituent parts of the frame incorporate ribs and reinforcements capable of providing the frame with a resistance similar to that of a frame consisting of metal parts.
- the plastic frame obtained with the process object of the invention has numerous advantages over those currently used, such as the following:
- Figure 1. Shows an exploded perspective of all the pieces that constitute the frame, including the accessory elements.
- Figure 2. It shows a side in which different possibilities of height of the leg and inclination of the shoes are illustrated, which can be obtained with the process object of the invention.
- Figure 3. Shows a schematic representation of the mold used to obtain sides, formed by a fixed part and an interchangeable part
- Figure 4. Shows a series of various configurations for the interchangeable part of the mold for obtaining the sides.
- Figure 5. It shows two possible final configurations of the backrest, obtainable with the method of the invention, backrests that integrate the elastic bands that make springs and the fixing means of the different accessories.
- Figure 6. It shows a seat obtained in a single piece according to the method object of the invention, integrating the elastic bands that act as springs, as well as the boxes and other elements for the integration of the tilting axis and folding springs.
- Figure 7. Shows a perspective of a finished armchair, observing in a cut for this purpose the layers of polyurethane in which the pieces of the frame constituting the backrest and the seat are embedded.
- the frame object of the invention is constituted essentially by a pair of sides (1), a seat (2) and a backrest (3), the frame being completed with the corresponding closing caps (4) (5) (6) and (7), as well as other auxiliary elements, such as armrests (8).
- the sides (2), backrests (3) and seats (4) are each obtained from a single mold, consisting of a fixed part (9), which corresponds to most of the piece to be obtained, and on an interchangeable part (10), so that depending on the configuration of this interchangeable part (10) pieces with different shapes and / or dimensions are finally obtained.
- the side for Armchairs object of the invention is constituted by a single piece body obtained by molding, entirely in plastic, and in which three distinct parts are distinguished, and which correspond to: a body or side proper (11), a leg (12 ) and a support shoe
- the support shoe (13) is of trapezoidal configuration and widened with respect to the intermediate part or leg (12), with holes (14), slightly inclined for mooring to the floor of the armchair and which are closed by the classic plugs .
- the intermediate part or leg (12) is approximately straight and is provided on both sides with a plurality of stiffening ribs (15) of the structure.
- the upper part or body (11) of the side determines a perimeter profile (16) with an internal soul (17), in which a large window or emptying (18) is established, approximately concentric with the contour general body (11), which provides a lightening of the side.
- the body (11) also has a series of holes (18) for quick coupling of the covers (4) and (5) that will have some lugs
- the body (11) on the side has housings (21) for anchoring the corresponding backrest (3), these housings being distributed to allow the mounting of the backrest (3) with different inclinations, as desired . It also has housings (22) through which the tilting shafts for the seats (2) are introduced transversely, a series of holes (23), arranged in the area, being also provided. front of the body (11), and offset in height and distance, ' to allow the assembly of the seat (2) in a fixed position (without the possibility of tilting), but with the possibility that it is arranged with different inclinations with respect to the ground.
- the described side is obtained by molding in one piece, using for this purpose, as shown in Figure 3, a single mold that is composed of a fixed part (9) and an interchangeable part (10), so that the fixed part (9) will configure the body (11) of the side that is common to all of them, while the interchangeable part
- leg (12) will correspond to the leg (12) and anchor shoe (13), so that depending on the configuration of the interchangeable part (10), the leg (12) will have a greater or lesser length and the shoe (13 ) a greater or lesser inclination, with which with the same mold it is possible to obtain directly sides with different inclinations to adapt to the different inclinations of the ground, as well as with a greater or lesser height to allow the seat to be at the required distance from the I usually.
- Figure 5 shows a backrest (3), also made entirely of plastic and obtained in single-piece molding, which is composed of a support or perimeter frame (24) and a series of longitudinal bands or strips ( 25), which provide the backrest with the elasticity provided by the springs of conventional frames.
- the perimeter frame (24) has a series of longitudinal ribs (26), that is, concentric and perimetral, designed to provide the required stiffness and resistance to the backrest, while the transverse bands (25) are provided with ribs (27). ), both transverse and longitudinal, to provide the aforementioned bands (25) with sufficient rigidity but maintaining the necessary elasticity.
- the backrest (3) is obtained from a single mold, which is constituted by a fixed part and an interchangeable part, the fixed part corresponding to the lower and central section of the backrest that is common to all of them, while the interchangeable part It is intended to obtain the upper part of the backrest, which can therefore have various lengths and / or configurations, as seen in the dashed lines of Figure 5.
