INTEGRAL ANTISEISMIC DOOR FRAME

Abstract

The present invention relates to an integral antiseismic door frame or seismic shock dissipation door frame adaptable to climate changes, which controls movements for all types of vertical or horizontal communicational involvement on foot within a dwelling, either house or building for general use. The door frame is composed of a plurality of components having different geometrical shapes, masses, densities and elasticities, joined together to form an energy dissipater or force damper in an integral frame comprising one or more multidirectional energy dissipaters which are assembled perpendicularly thereto. During installation it can be adapted to variations in the parallelism of the side and top walls when anchoring thereto due to other elements made either of wood, plastic, iron or the like, which are installed lengthwise to increase its width and correct the parallelism of the walls, if necessary, without altering its energy dissipation properties. The components integrated in the integral door frame interact with each other, dissipating the energy exerted by the walls on the door, controlling loads, movements and deformations, maintaining normal operation of the door, preventing the obstruction thereof and at the same time jamming of the lock, such that it is possible to open the door during and after a seism or earthquake or when the door is affected by changes in the relative humidity of the environment.

DESCRIPTION OF THE INVENTION

[0019] FIGS. 1 to 8 describe an integral antiseismic door frame or seismic shock dissipation door frame, either in a dwelling, house or building. The present invention refers to an integral antiseismic door frame or seismic shock dissipation door frame comprised of a plurality of elements of different geometrical shapes, masses, densities and elasticities joined together. The door frame may also be configured as a single injected piece characterized by zones. The door frame is comprised of a head jamb (1) and two side jambs (2) of the same length which control the movements and loads exerted by the wall on the door (see FIG. 2).

[0020] In the door frame, the jambs (1, 2) have one or more parallelism correction elements (see FIG. 8).

[0021] In the integral door frame, there is inserted a multidirectional energy dissipater (9) at its longitudinal axis (see FIG. 5).

[0022] In the door frame, the jambs (1, 2) comprise a first rigid plate (6) which provides a support surface with the wall and which is mounted to an energy dissipation element (7) which in turn is mounted to a polygonal structural support (8), wherein one or more multidirectional energy dissipaters (9) are assembled perpendicularly to the elements (6), (7) and (8) (see FIG. 3).

[0023] In the integral door frame, the density of the energy dissipation element (7) is less than the density of the elements (6), (7) and (8) (see FIG. 3).

[0024] In the integral door frame, the polygonal structural support (8) has an angle of inclination greater than 90 at the contact area with the door (see FIG. 3).

[0025] In the integral door frame, the jambs (1, 2) are configured as single injected pieces where there can be distinguished a wall contact zone (11), which provides a support surface with the wall, a load and energy dissipation zone (12) with polygonal interstices and a polygonal structural zone (13), wherein one or more multidirectional energy dissipaters (9) enable assembly to the wall (see FIG. 6).

[0026] In the integral door frame, the polygonal structural zone (13) has an angle of inclination greater than 90 at the contact area with the door (see FIG. 6).

[0027] In the integral door frame, the rigid plate (6) is made of metal, a metal alloy or a natural or synthetic polymer.

[0028] In the integral door frame, the energy dissipation element (7) is made of a natural or synthetic rubber, polymer or elastomer.

[0029] In the integral door frame, the polygonal structural support element (8) is made of wood, metal, a metal alloy or a natural or synthetic polymer.

[0030] In the integral door frame, the multidirectional energy dissipater (9) is made of a natural or synthetic rubber or elastomer.

[0031] In the integral door frame, the jambs (1, 2) are configured as single injected pieces made of a natural or synthetic rubber, elastomer or polymer.

[0032] When the head jamb (1) and side jambs (2) of the same length plus the parallelism correction element (3) between the head jamb (1) or the side jambs (2) and the wall (4), if required, are assembled together, an integral frame configuration is produced, capable of dissipating deformation and thus preventing obstruction of the door (5) (see FIG. 1).

Head Jamb

[0033] The head jamb (1) is comprised by a first rigid plate (6), made either of wood, plastic, iron or a similar material, that provides a support surface with the wall and has some through-bores, equidistantly or irregularly spaced depending on the needs of its installation. The first rigid plate (6) is mounted to an energy dissipater (7) which has concentrically aligned bores with said latter bores. The head jamb (1) assembly then continues with a polygonal structural support element (8), made either of wood, plastic, iron or a similar material and which does not exclude curved configurations also, that provides rigidness to the assembly. Elements (6), (7) and (8) are physically joined together through chemical means, which can be an adhesive, thermo-chemical means such as vulcanization or a physical or mechanical means such as a screw, bushing or similar element in such a way as to maintain the joint for generating in this way proper functioning of energy dissipation altogether.

[0034] Further, the head jamb (1) can also be configured as a single injected piece, either made of a polymer, plastic or similar material, by making the densities, mechanical properties and bores of elements (6), (7) and (8) the same so as to form an energy dissipater or force damper. Such a head jamb (1) is comprised of: a first rigid zone (11), which is designed to provide a support surface with the wall, the same as element (6); while freedom of movement is allowed by means of a second zone (12) of polygonal geometric interstices designed to provide an even distribution of the stresses, the same as the energy dissipater (7), wherein the interstices contract or expand depending on the direction of the loads during an earthquake or due to seasonal climate changes or changes in relative humidity which expand or contract the door against the frame; and, the same as the polygonal structural support element (8), a third polygonal structural rigid zone (13), which in its shape can have or not an angle greater than 90 at the area of contact with the door to reduce direct friction.

[0035] The head jamb (1) carries a multidirectional energy dissipater (9) physically and perpendicularly joined to the polygonal structural support element (8) through chemical means, which can be an adhesive, or through thermo-chemical means such as vulcanization, or else joined to the polygonal structural rigid zone (13) through a bore of the same diameter and concentric with the other bores, enabling the multidirectional energy dissipater (9) to respectively make contact with the energy dissipating element (7) or the second zone (12) of polygonal geometric interstices and operate to dissipate structural deformations in other degrees. As a result it prevents loading on the attachment to the wall and gives the polygonal structural support element (8) or polygonal structural rigid zone (13) freedom to move 360 and in all the combinations of the X, Y and Z Cartesian planes. At its longitudinal axis the multidirectional energy dissipater (9) has a bushing (10) inserted, which is an essential central reinforcement that permits anchoring the head jamb (1) to the wall, enabling dissipation of the loads over the anchorage and not rigidizing the whole (See FIGS. 3, 5 and 6).

Side Jamb

[0036] The side jamb (2) is comprised by a first rigid plate (6), made either of wood, plastic, iron or a similar material, that provides a support surface with the wall and has some through-bores, equidistantly or irregularly spaced depending on the needs of its installation. The first rigid plate (6) is mounted to an energy dissipater (7) which has concentrically aligned bores with said latter bores. The head jamb (1) assembly then continues with a polygonal structural support element (8), made either of wood, plastic, iron or a similar material and which does not exclude curved configurations also, that provides rigidness to the assembly. Elements (6), (7) and (8) are physically joined together through chemical means, which can be an adhesive, thermo-chemical means such as vulcanization or a physical or mechanical means such as a screw, bushing or similar element in such a way as to maintain the joint for generating in this way proper functioning of energy dissipation altogether.

[0037] Further, the side jamb (2) can also be configured as a single injected piece, either made of a polymer, plastic or similar material, by making the densities, mechanical properties and bores of elements (6), (7) and (8) the same so as to form an energy dissipater or force damper. Such a side jamb (2) is comprised of: a first rigid zone (11), which is designed to provide a support surface with the wall, the same as element (6); while freedom of movement is allowed by means of a second zone (12) of polygonal geometric interstices designed to provide an even distribution of the stresses, the same as the energy dissipater (7), wherein the interstices contract or expand depending on the direction of the loads during an earthquake or due to seasonal climate changes or changes in the relative humidity which expand or contract the door against the frame; and, the same as the polygonal structural support element (8), a third polygonal structural rigid zone (13), which in its shape can have or not an angle greater than 90 at the area of contact with the door to reduce direct friction.

[0038] The side jamb (2) carries a multidirectional energy dissipater (9) physically and perpendicularly joined to the polygonal structural support element (8) through chemical means, which can be an adhesive, or through thermo-chemical means such as vulcanization, or else joined to the polygonal structural rigid zone (13) through a bore of the same diameter and concentric with the other bores, allowing the multidirectional energy dissipater (9) to respectively make contact with the energy dissipating element (7) or the second zone (12) of polygonal geometric interstices to and operate to dissipate structural deformations in other degrees. As a result it prevents loading on the attachment of the jamb to the wall and gives the polygonal structural support element (8) or polygonal structural rigid zone (13) freedom to move 360 and in all the combinations of the X, Y and Z Cartesian planes. At its longitudinal axis the multidirectional energy dissipater (9) has a bushing (10) inserted, which is an essential central reinforcement that permits anchoring the side jamb (2) to the wall, enabling dissipation of the loads over the anchorage and not rigidizing the whole (See FIGS. 4, 5 and 7).

Parallelism Correction Element

[0039] The wall parallelism correction element (3) is an independent element that is installed between the wall and the head jamb (1) or side jambs (2) of the same length and which can be made of wood, plastic, iron or similar material with guiding through-bores which are equidistantly or irregularly spaced, depending on the needs, and are concentrically aligned with the side jamb (1, 2) anchoring perforations. This allows correction of variations in the perpendicularity of the walls, providing a correct installation without affecting the aforementioned mechanical and energy dissipation properties. Another characteristic is that to correct larger variations several of these elements can be superimposed (see FIG. 8).
