ARRANGEMENT FOR A MOULDING

Abstract: The present invention relates to an arrangement for filler bodies (8, 9) for filling cavities (11) inside a casing. Filler bodies (8, 9) consisting of rubber or a similar elastic material exhibit a number of non-rigid movable counter-pressure devices (12, 13), which, when in the extended position, are so arranged as to be capable of interacting with stops. Effective retention, amongst other things, is permitted in this way.

Description: Arrangement for a moulding The present invention relates to an arrangement for a filler body for filling cavities inside casings. The efficient production of, amongst other things, profiles which are designed to accommodate a filling of some kind internally inside cavities has not proved easy to achieve until now. Production by craftsmen involving the introduction of the filler bodies in question by hand has been found to take a long time, to be very costly, and not to have functioned entirely satisfactorily without the need to use special metal reinforcement inserts in the filler bodies. In the case of frame profiles in particular, which are designed to be assembled in conjunction with other constituent parts of a structure with the help of fastening elements introduced into said frame profile, it is important for production to meet all the essential production requirements, i.e. it must be rapid, effective, reliable and acceptable from the point of view of cost. The principal object of the present invention is thus first and foremost to solve the aforementioned problems by simple and financially acceptable means. Said object is achieved by means of an arrangement in accordance with the present invention, which is characterized essentially- in that a filler body consisting of rubber or a similar elastic material exhibits a number of .non-rigid movable counter-pressure devices, which, when in the extended position, are so arranged as to be capable of interacting with stops. The invention is described below as a preferred illustrative embodiment, in conjunction with which reference is made to the accompanying drawings, in which: Fig. 1 shows a sectional view through part of a window to which arrangements in accordance with the present invention have been applied; Figs. 2 and 2A show a sectional view and a longitudinal view respectively of the arrangement accommodated in a profile moulding; Figs. 3 and 3A show a sectional view and a longitudinal view respectively of a connecting device; Figs. 4 and 4A show a sectional view and a longitudinal view respectively of joining devices interacting between filler bodies; Fig. 5 shows a perspective view of a filler body; Fig. 6 shows a perspective view of filler bodies accommodated in a profile channel. An arrangement in accordance with the present invention can be applied in many different areas, although for the sake of simplicity the invention is described below in relation to mouldings designed to be applied in the production of windows. In a window of the kind shown in the drawings in Fig. 1, the joining of the window profile sections 1, 2; 3, 4 to one another in pairs is effected with the help of filler bodies 8, 9 and joining devices 7, which have connecting devices 5, 6 capable of interacting with the filler bodies 8, 9. It is thus possible for all the casement elements and sill elements of a window to be provided with an arrangement 10 in accordance with the present invention. Said filler bodies 8, 9, which are preferably so arranged as to interact with one another in pairs when accommodated as a filling inside a cavity 11 in a casing, consist in accordance with the present invention of rubber or some other similar elastic material or materials. They also exhibit a number of non-rigid movable counter-pressure devices 12, which, when in the extended position, are so arranged as to be capable of interacting with stops 13. The counter-pressure device 12 and the stop 13 preferably consist of non-rigid resilient body parts arranged in separate filler bodies 8, 9- Filler bodies 8, 9 arranged opposite one another in pairs in such a way as to be capable of being introduced in a removable fashion into a profile 1 , which filler bodies exhibit counter-pressure devices 12, 13 arranged in the respective filler body 8, 9 in a direction facing towards the opposing filler body 8, 9, are able to interact in pairs with the help of said counter-pressure devices 12, 13 so as to force the filler bodies 8, 9 in a direction 15, 16 away from one another. Counter-pressure devices 12, 13 preferably executed as tongues extend together along one lateral surface 8A, 9A of the filler body in question, preferably situated at separate levels from one another on a common filler body 8, 9. Cavities executed as a profile moulding 14 have gripping devices 19, 20 projecting inwards towards the cavity 11 inside the casing at the respective side wall parts 17, 18, which gripping devices are preferably formed by flanges on the profile moulding facing one another. Said filler bodies 8, 9 exhibit recesses 21, 22 so arranged as to be capable of accommodating the gripping devices 19, 20, which are situated in the moulding 14. The overall internal width 2 x B of tightly compressed filler bodies 8, 9, which are capable of being accommodated turned with their sides bearing counter- pressure devices facing towards one another, preferably exceeds the width V of a profile leati-in opening 40. The lateral surfaces 8A, 9A of the filler bodies 8, 9 intended for connecting purposes, which exhibit counter-pressure devices 12, 13 extending preferably for the whole length of the filler bodies 8, 9 in the form of resilient elastic wings, are designed to make contact along and to be capable of interacting with joining devices 7 capable of being introduced between them in the connected securing position. Connecting devices 5, 6 preferably of arrow- shaped cross-sectional form arranged on the joining device 7 are so arranged aε to be accommodated by a groove or grooves 23, 24 adapted with an essentially congruent form arranged along the longitudinal extent L of said filler bodies. In pairs of combined filler bodies 8, 9 said grooves 23, 24 form accommodating spaces 25, 26 with a preferably arrow-shaped cross-sectional form between them at the grooves 23, 24, so designed, after introduction of the joining device 7 into a gap 27 formed between the -filler bodies 8, 9, as to be capable of accommodating its own connecting device 5, 6 in the joining device 7. Said counter-pressure device 12, 13 executed as a long tongue or flap on the respective filler body 8, 9 is so arranged, when in the retracted position, as to be accommodated in a suitable cavity 28, 29 so as to permit sufficient space for a centrally located shaft 30 on the joining device 7 to be accommodated in the gap 27 formed between the filler bodies 8, 9. Effective retention of the filler bodies 8, 9 a ter they have been introduced into the moulding 14, which is preferably made of metal, plastic or some other suitable material, without the risk of the filler bodies 8, 9 falling out of the cavity 11 inside the casing in which they are accommodated, is now permitted by the fact that the counter-pressure devices 12, 13 interact with one another in pairs from filler body 8 to filler body 9, or individually against some other suitable stop which attempts to prevent further 'deflection of said counter- pressure devices 12, 13 in the direction of deflection 31. They attempt instead to be forced back in the direction of deflection 32 before the joining device 7, for example, or some other device which it is wished to retain has been introduced into the remaining part of the cavity 11 in which said filling body 8, 9 is accommodated. Any vibrations occurring in elements joined together using the invention are also absorbed effectively by the damping function of the filler bodies 8, 9. Thermal bridges from the outside and inwards, for example a window, as shown in the illustrative embodiment presented in the drawings in Fig. 1, are now -effectively avoided thanks to the invention. The connection of, for example, the window components 2, 4 to the components 1, 3 takes place by means of, for example, the joining devices 7 which are integrated with or in some other way joined to the outer components 2, 4, which joining devices are introduced in the direction of the arrows 33, . 34 between the filler bodies 8, 9 introduced beforehand into the respective window profiles 35, 36, which filler bodies are of the kind described above and are retained in position in the components 1, 3 by means . of associated counter-pressure devices 12, 13. The introduction of the joining device 7 between the filler bodies 8, 9 causes said counter-pressure devices 12, 13 to be deflected into associated adjacent cavities 28, 29 in the filling bodies 8, 9. The filling bodies 8, 9 are forced sideways 15, 16 in this way against the lateral flanges 17, 18 of the profiles 35, 36. The connecting devices 5, 6, which can be arranged with ' an arrow-shaped cross-sectional profile suitable to be accommodated in associated accommodating spaces 25, 26, are introduced into them, when effective and secure retention of the components 1, 2; 3, 4 is achieved. The components 2, 4 are effectively prevented from being pulled out, partly by the excellent frictional interaction between the bodies 8, 9, the lateral flanges 17, 18 and the joining device 7, and partly because the bodies 8, 9 act both laterally 15, 16 and in the direction 33, 34 in order to hold the components 2, 4 effectively to the components 1, 3. The invention is utilized here in the form of the illustrative example for the purpose of joining together various components, although it is equally well suited for other applications. Mention may be made, for example, of its use for the reinforcement of structural elements to which it is wished to impart characteristics of angular stability, for example the frames of buildings, vehicles, cabinets and containers, etc. , but without having to use reinforcing elements made of metal or other cost- increasing and weight-increasing inserts. The possibility of using resilient materials other than rubber in the present invention may arise, although rubber materials (both natural rubber and synthetic rubber) exhibit so many advantageous properties, such as high internal damping, good sound absorption, good elastic formability, resistance to chemicals, good wear characteristics, and high flexibility, etc., for -all of which reasons said material is to be preferred, although plastic materials or a combination of various materials could also be used. The filler bodies 8, 9 are introduced into the profile moulding 14 via the longitudinal opening 40 of the moulding, with one filler body 8 slightly in front of the other 9, such that the first filler body 8 will have been displaced laterally into the intended accommodating position before the second filler body 9 is introduced via the opening 40. The invention is not restricted to the illustrative embodiment described above and shown in the drawings, but may be varied within the scope of the patent claims without departing from the idea of invention. For example, the function of the counter- pressure devices 12, 13 may be doubled, with the joining devices 7 accommodated in the cavity 11 inside the casing, by arranging these devices 12, 13 in such a way that they make contact with the connecting devices 5, 6 of said joining device 7, and preferably with the rear side of the thickened area which is preferably in the form of an arrow point. Said devices 12, 13 are dimensioned in this case so as to be capable of performing both the aforementioned functions.
