Definitions
- Object of this invention is to provide a pressure-hooking structure for seal and back stop gaskets and for the connection of accessory to various sections, particularly suited for extruded metal sections, such as hollow sections from aluminium and its alloys, utilized for door- and window frames and the like.
- the full-height seats for the stable housing of a gasket are obtained during the extrusion of the section in various positions, i. e. either on the walls of the quadrangular hollow body of the section or on the usual flange normally protruding coplanary from the opposing walls. shorter than the through-section of the section.
- said seats are constituted by grooves or throats having a substantially constant C-shaped through-section, which protrudes from the wall or flanges of the section and which develops for the whole height of the section. Therefore, the various continuous gaskets are fitted in the "C"-shaped seats, starting from an end of the section, and the restraint is ensured by the part enclosed in the seat, while the part which protrudes outside it is the real gasket which may have different shapes and sizes according to the function required.
- CH-A-406592 discloses a gasket made of elastic material having a peduncle provided with lateral longitudinal protrusions fitted in a channel-shaped seat, said channel seat having a rectangular or a dovetail or similar shaped section.
- US-A-3229332 discloses a window construction incorporating a sash which exhibits two ribs directed towards a frame; the spacing between the frame and the sash is bridged by two protruding strips of an elastic flexible material, e.g. rubber or plastic, and inserted and held into rectangular groves of the frame by means of a peduncle provided with lateral longitudinal protrusions.
- an elastic flexible material e.g. rubber or plastic
- FR-A-2166486 discloses a gasket for wood works inserted and held into rectangular groves by means of a peduncle provided with longitudinal protrusions (saw-toothed); the peduncle inserted into the grove is realized less elastic than the protruding part of the gasket which constitutes the sealant part.
- object of this invention is to provide a hooking structure for various types of continuous gaskets for metal sections and the like, so designed as to allow the hooking and the removal of the gasket from its seat, without having to disassemble the frame or the shutter or any composite structure composed by metal sections, should it be necessary.
- Another object of this invention is to provide a hooking structure of the aforementioned type, so designed as to be obtainable during the extrusion of the section, with no need for particular operations nor additional costs.
- a further object of this invention is to provide a set of continuous gaskets easily and quickly anchorable in the relevant seats and easily removable and replaceable.
- a further not least object of this invention is to provide a hooking structure so designed as to constitute also an efficacious restraint and locking means for accessories of door- and window frames, for various types of sections, for glass stops, for various type of hinges and the like.
- a door- and window frame composed by extruded hollow sections from alluminium and its alloys comprising a hooking and gasket restraining as well as connecting metal sections (2, 3) and/or accessories structure constituted by a continuous channel-shaped seat (1) having a constant substantially "U"-shaped through-section and comprising also a set of continuous gaskets, characterized in that said channel- "U"-shaped seat (1) positioned on the sides and on the flanges of said sections (2, 3) is provided with a flange (1a, 1b) shaped at right angle in respect of the wings of said seat (1) protruding externally towards the outside of the seat (1) and running longitudinally along the edge of at least one of said wings, the channel-shaped cavity of said seat (1) being suitable to pressure-house the peduncle or stem (4) of said continuous gaskets whose part outside the seat is variously shaped so as to provide a set of seal and back stop gaskets, said pro
- the peduncle of said gasket which has to be pressure-inserted in the seat, is provided peripherally with protrusions having a substantially rounded shape, or a saw-teeth shape or a dovetail shape or the like.
- these gaskets are partly made from polyvinylchloride (PVC), polyethylene, polypropylene, ABS, fluorinated rubbers and the like, and partly constituted by a peduncle from PVC or the like, coextruded, for the external bent part, with flexible rubber or the like.
- PVC polyvinylchloride
- ABS polypropylene
- fluorinated rubbers and the like are partly made from polyvinylchloride (PVC), polyethylene, polypropylene, ABS, fluorinated rubbers and the like, and partly constituted by a peduncle from PVC or the like, coextruded, for the external bent part, with flexible rubber or the like.
- the pressure-hooking structure subject matter of this invention is substantially constituted by the combination of a particular continuous seat with a set of gaskets also continuous and differently shaped as concerns their external part, i.e. the part that protrudes from said seat.
- the restraint seat obtained, for instance, on the various sides and flanges of the two sections 2 and 3 to be hooked with one another to form, for instance, a frame made up by two hollow sections from alluminium or its alloys, is constituted, according to the invention, by a groove or throat 1 developed along the full-height of the section, and having a substantially "U"-shaped through-section, whose side flanges are parallel to one another; therefore the stem or peduncle of a gasket can be inserted into said "U"-shaped channel by simple lateral pressure-insertion and stably kept therein by the particular conformation of the stem or peduncle of said gasket, as will be better explained further on.
- each "U"-shaped seat 1 The free ends of the opposing flanges of each "U"-shaped seat 1 are provided with at least a flange 1a (or with two flanges 1a and 1b), bent towards the outside or having a substantially triangular through-section.
- Said external flanges are as many useful means for snap-hooking and restraining a section with another section, provided with corresponding protrusions or with an accessory, for instance a hinge, to form door- and window frames, as shown by way of example on Fig. 1 (and on Fig. 9).
- the gaskets shown in through-view on Figs. 2 through 8, have all a same stem or peduncle 4, whose size allows it to be stably housed in the "U"-shaped seat by lateral pressure plug-in; to ensure the stability of the plug, stem 4 is provided with transversal protrusions or ribs 5, having a rounded shape, a saw teeth shape, a dovetail shape, a spiral shape or the like, suitable to prevent the risk of the gasket coming out from the relevant seat.
- gasket 6 of Fig. 2 has a flat part 6a integral with stem 4, which rests against the edge of the "U"-shaped seat and then a continuous bent part 6a, elastically yielding under pressure, whose function is to constitute an efficacious back stop between the various sections matching with one another, as indicated, for instance, on Fig. 1 in the space between section 2 and section 3, mobile around hinge C, and also a sealing means in the space Y between said sections.
- Gasket 11 of Fig. 7 has the same function as the gasket of Fig. 6, i.e. that of constituting a ledge between sections matching with one another, and has the flat part 11a, which rests against the Edge of the "U"-shaped seat, and the tubular part 11a, which is a sealing element yielding under pressure and provided also with a recess 11a suitable to help the squashing of the tubular part in the wished direction and the relevant sealing, as shown on Fig. 9.
- Gasket 7, shown on Fig. 3 is provided with two angle-flanges 7a-7b, integral with stem 4, which rest on the external inclined surfaces of flanges 1a-1b of the "U"-shaped seat, as shown in the middle of Fig. 1, and a tail 7c ending with a hook-bent part 7d. Its function is that of constituting a seal against another gasket, as illustrated, for instance, also in the middle region of Fig. 1.
- Gasket 12 shown on Fig. 8 has a flat part 12a, integral with stem 4, which rests against the edge of the "U"-shaped seat, and then an extended part 12b elastically yielding and ending with the inclined part 12c, which forms a seal against part 12b of a similar gasket positioned in opposing position within the matching section, as shown on Fig. 9, or against a special protrusion, not shown on Fig. 9, obtained on the extruded section.
- two gaskets 12, equal and in combination with one another may be used instead of the combination of gaskets 7 and 8, with obvious advantages of cost and installation simplicity.
- Gasket 8, shown on Fig. 4 has a flat rest surface 8a, integral with stem 4, having the function of a levelled back stop or the like against a section, a glass pan or the like.
- Gasket 9 of Fig. 5 is provided with a tail 9a integral with stem 4, which tail is bent according to a wide bending radius and rests as a seal against a glass pan or also against a wide section surface; besides, its part 9b, bent parallelly to the stem, seats astride a flange 1a or 1b of the "U"-shaped seat, to ensure the plug stabiity of the gasket, when it is mounted.
- Gasket 10, shown on Fig. 6, is a composite gasket, i.e. constituted by the coextrusion of a rigid plastic material, for instance PVC, for stem 4 and the external part 10a, and by a bent part 10b from flexible plastic material, for instance flexible rubber; part 10b has substantially a function of seal against air infiltrations or the like in a structure of sections, as shown by way of example in the middle part of Fig. 1.
