Abstract
Description
- This invention relates to a synthetic plastics material window-frame for windows and the like applications, of a type which comprises a frame and at least one wing supported on the frame, sides of said frame and said at least one wing including respective box-type moldings.
- As is known, window-frames made of a synthetic plastics material, such as polyvinylchloride, have met with widespread acceptance on the market, both on account of their affording durability and stability over time and of their limited cost and virtual freedom from maintenance problems even in severe environmental conditions.
- Such window-frame are usually comprised of box-type moldings or profile members wherein longitudinally extended chambers are formed. In addition, metal inserts are provided within said chambers to form a reinforcement of sort as is required to ensure that the window-frame has adequate strength and stability to withstand the static and dynamic loads anticipated therefor, pursuant to the provisions of well-known and specified safety regulations. One of such frames is disclosed by DE-A-2117397, according to which rib formations are provided extending along at least a part of the moldings, the rib formations being formed integrally with the respective moldings.
- However, conventional window-frames of synthetic plastics do not generally lend themselves for large-size windows and the like applications. In fact, owing to the low strength and inherent stiffness of such materials, conventional large-size window-frames would be subjected to unacceptable bending and deforming stresses.
- It is the object of this invention to provide a synthetic plastics material window-frame which has such constructional and performance characteristics as to be also usable for large-size windows and the like, in conformity with enforced safety regulations, and can obviate the cited drawbacks in connection with the background art.
- This object is achieved according to the invention by a window-frame as specified in claim 1.
- The window-frame of this invention advantageously includes a chamber formed longitudinally within said rib formation, and a stiffening insert of metal fitted in said chamber.
- The features and advantages of a synthetic plastics material window-frame according to the invention will become apparent from the following detailed description of a preferred embodiment thereof, to be taken in conjunction with the accompanying illustrative and non-limitative drawings.
- In the drawings:
- Figure 1 is a perspective view showing in diagramatic form a window-frame according to the invention;
- Figure 2 is a fragmentary, sectional plan view of the window-frame of Figure 1, taken along the line II-II therein; and
- Figures 3, 4, and 5 are enlarged scale sectional views of respective details of the inventive window-frame.
- With reference to the drawing figures, the numeral 1 generally designates a window-frame for a large-size window of the two-winged variety, made of a synthetic plastics material such as a rigid shock-resistant polyvinylchloride.
- The window-frame 1 has an
outward front 1a and an oppositeinward front 1b, and comprises aframe 2 adapted for installation tomasonry work 3 in a manner known per se. - Upper 2a and lower 2b major sides, and oppositely located
minor sides frame 2. - The window-frame 1 further comprises first and second wings, respectively designated 4 and 5, which are supported on the
frame 2 by means ofhinges 6. - More specifically, upper 4a and lower 4b minor sides, and oppositely located
major sides first wing 4, whilst indicated at 5a and 5b are the upper and lower minor sides of thesecond wing 5, and at 5c and 5d the oppositely located major sides thereof. Furthermore, thehinges 6 are mounted between thesides 2c of theframe first wing 4, as well as between theside 2d and theside 5d of thesecond wing 5. - The sides of the
frame 2 and thewings - Indicated at 7 is an additional box-type PVC molding extending along, and being attached to, the
molding 5c so as to form an abutment center upright for theside 4d of thefirst wing 4. - A plurality of
chambers molding 2a-2d, 4a-4d, 5a-5d, and 7, extending longitudinally therethrough. Arespective metal insert 9 is provided in thechambers 8a which comprises a steel sectional member of C-shaped cross-section. - The
moldings 4a-4d and 5a-5d of thewings respective seats 10 providing holder cappings forglass panes 11 to be mounted in said seats, two on eachwing - In accordance with the invention, the window-frame 1 has on its
outward front 1a respectivetubular rib formations 12 extending along themoldings 2a-2b, 4a-4b, 5a-5b, and 7. Eachtubular rib formation 12 is formed integrally with its related molding and has a relatively large size which is substantially proportionate with that of the molding itself, i.e. dimensions of the order of the moulding. - It is important to observe that each
tubular rib formation 12 has a substantially semicircular cross-sectional shape, and achamber 13, also substantially semicircular in cross-section, formed longitudinally therethrough. - The
chambers 13 accommodate respectivestiffening metal inserts 14 of tubular shape which are supported onspacer lugs 15 extending into thechambers 13 and a unitary construction with thetubular rib formations 12. - The window-frame 1 further includes a
respective groove 16 formed longitudinally in eachtubular rib formation 12 near an outermost generatrix line thereof and being open outwardly. Snap fitted into thegrooves 16 are respectivedecorative trimmings 17. - The synthetic plastics material window-frame of this invention has shown to be significantly stronger, stiffer, and stabler than the conventional window-frame and lends itself, therefore, advantageously for use with large-size windows and the like, in particular of dwelling and office buildings, as well as for the restoration of historical buildings.
- Of special advantage has shown to be, moreover, the provision of tubular rib formations semicircular in shape which, while being compact in size, can accommodate tubular stiffening inserts of metal. Furthermore, the very shape and framing arrangement of such tubular rib formations are suitable to confer substantial aesthetic value on the window-frame.
- A further advantage of the window-frame is that the grooves provided along the tubular rib formations may be readily utilized to support dimming and radiation attenuating arrangements for the glass panes.
