Description

SPECIFICATION Glass panel structure The present invention relates to glass panel structures for mounting in window frames, door frames or the like.
Glass panel structures of the glazed type include two or more glass panes spaced apart from one another by a spacer to provide an air space therebetween which acts as an insulator against heat and cold. These glass panes are mounted in a framework which is rigidly connected to the peripheral edges of the glass to form a unitary glass panel which is fixed, hinged or slidable in a door frame, window frame or the like. However, should one, or both, glass panes become defective or broken, the entire glass panel unit must be scrapped since the framework is so mounted to the glass panes that it cannot be dismantled for use in association with other glass panes.One example of such conventional structure may be found described in applicant's Belgium patent No. 861,815 issued March 31, 1978, in which a monoblock structure is disclosed asxincluding a framework consisting of permanently attached metallic members which are sealed to the outer marginal edges of the glass panes, and a series of border elements made of plastics material surrounding the metallic members.
It is an object of this invention to provide a glass panel structure for use in a window or door frame, whether sliding, hinged or fixed, wherein a series of border elements form of rigid vinyl plastics material are peripherally sealed to the outer marginal edges of the glass panes to form a self-contained glass pane unit and wherein at least the two opposite vertical sides of the unit consist of metallic members which are interlockingly engaged with its corresponding border element so that, should the glass pane unit become defective, the metallic members can be manually removed and mounted on a similarly constructed glass pane unit or should the metallic members themselves become defective, a new set of members may be installed to the pane unit.
The present invention therefore provides a glass panel structure for use in a window or door frame comprising: a hermetically sealed panel consisting of at least a pair of glass panes arranged in spaced parallel relationship and of a spacer disposed between the inner marginal edges of the panes and sealingly connected thereto to form a self-contained glass pane unit; a series of border elements, formed of rigid plastics material, e.g. a rigid vinyl plastics material, peripherally extending about the self-contained glass pane unit, the border elements being firmly attached to at least one of the glass panes along the outer marginal edge thereof; and a metallic member extending at least along the two opposite vertical sides of the pane unit, each metallic member being interlockingly engaged with a corresponding border element to form a structural unit with the glass panes, each metallic member being manually removable from the border element for substitution purposes.
In one preferred form of the invention, the engagement and disengagement of the metallic members onto and from the border elements may be accomplished by a snap-in engagement between cooperating means on the engaging faces of the metallic members and of the border elements.
In another form of the invention, engagement and disengagement are accomplished by relative longitudinal sliding movements of the metallic members to the border elements.
Other objects and scope of applicability of the present invention will become apparent from the detailed description given hereinafter; it should be understood, however, that this description, while indicating preferred embodiments of the invention, is given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art.
Referring to the drawings: Figure 1 is a cross-sectional elevation view of a glass panel structure made in accordance with the present invention in the form of a hingedly mounted window or door structure; Figure 2 is a cross-sectional elevational view of another embodiment of the present invention in the form of a sliding window or door; and Figure 3 is a cross-sectional plan view of another embodiment of the present invention.
Generally, the present invention relates to all kinds of window or door structures whether they are hingedly mounted, slidably mounted or fixedly mounted to a window or door frame; hence, the windows or doors given in the following description are only illustrative.
Referring to Fig. 1, there is shown a glass panel structure, generally defined as 10, which is the type of structure which can be hingedly mounted to a window or door frame 12. The structure of the window or door frame 12 not being an essential part of the present invention, a detailed description will not be given; however, it can be seen that the glass panel structure 10 is isolated from the frame 12 by means of a series of weatherstrips 14, 1 6, 1 8 and 20.
The glass panel structure 10 comprises a selfcontained glass pane unit 22 which consists of a pair of glass panes 24, 26 arranged in spaced parallel relationship to one another and of a spacer 28 which is disposed between the inner marginal edges of the panes. Spacer 28 is hollow and contains a weather desiccant 30 which is in communication with the air space between panes 24 and 26 by means of a suitable opening such as slit 32. One methods of securing the spacer 28 to the inner marginal edges of the glass panes is described in applicant's Canadian patent No.
833,267 issued February 3,1 970 or in applicant's Canadian patent No. 939,560 issued January 8, 1974, which method consists in applying a weather sealant between the two components, such as a high molecular weight hydrocarbon polymer produced by polymerizing isobutylene.
This dual pane glass unit 22 is self-contained in that it does not require an independent surrounding framework or sash for purpose of retaining and supporting the panes and giving rigidity to the structure.
A series of border elements peripherally extend about the self-contained glass pane unit 22. The border elements are formed of a rigid vinyl plastics material, such as a polyvinyl chloride known under the trademark GEON. These border elements are firmly attached to the glass panes; in the embodiment illustrated in Figures f and 3, the border elements are shown sealed to the glass panes whereas the border elements illustrated in Figure 2 are provided with a series of paneengaging longitudinal ridge projections on the inner faces of their upstanding arm portions.
Although not shown, a combination of both, ridge projections and sealant, is also possible.
An important feature of the present invention is that metallic members are provided in covering engagement with at least some of the border elements, the latter thus acting as an intermediate joining member between the glass panes and the metal; each metallic member thus forms a structural unit with the glass panes resulting in a sturdy assembly. In its simplest form, a window unit could only be made with the opposite vertical sides being covered with such metallic members; in other words, in some cases, the horizontal borders of a window unit would be formed of plastic extrusions only. However, is most preferred forms, all four borders of the glass unit will include plastic border elements covered with metallic members.
The border elements and their associated metallic members are so shaped so as to engage one another to provide a solid interlock when in engagement with one another; on the other hand, they must also be so shaped as to facilitate manual removal from one another when it is wished to disengage them by reason of a broken glass pane unit or of a defective metallic member.
The following description gives various forms of inter-engagement between border elements and metallic members.
In the embodiment illustrated in Fig. 1 , the border element is L-shaped with one upstanding portion 36 extending longitudinally along the outer marginal edge of glass pane 24 and a second horizontal portion 38 extending longitudinally adjacent the peripheral edges of glass panes 24,26. The border element 34 is sealingly joined to the unit 22 by means of an impervious sealant 39, such as a polysulphide polymer, which is laid between the outer marginal edge of glass pane 24 and the border element portions 36, 38. Portion 38 has two longitudinal projections 40 and 42 in alignment with the peripheral edges of the glass panes.
Extending over and engaged with the border element 34 is a metallic member 44 which includes two sections 46, 48 which are separated from one another by means of an insulating material 50, such as a solid urethane. Section 46 of the metallic member has an upstanding side portion with a flanged extremity 52 which fits in a correspondingly-shaped groove formed in the upper part of the border element portion 36.
Border element 34 being made of plastic material, engagement and disengagement of the metallic member to and from the border element can be effected by a snap-in or snap-out pivotal movement of the metallic member 44~ relative to the glass pane unit 22. The other section 48 of the metallic member has a tongue 54 which fits in a correspondingly-shaped groove of a flexible gasket 56 which is applied against the outer marginal edge of glass pane 26. One suitable material for gasket 56 is neoprene.
In this particular embodiment, should the glass pane unit 22 of the border elements 34 become damaged, defective or broken, the other components may still be used by manually pivoting outwardly the metallic member from the border element whereby tongue 52 may be disengaged from the groove of the border element.
Referring to Fig. 2, there is shown another embodiment of the present invention, in the case of a sliding door or window 60 mounted in an appropriate surrounding frame 62. Only one sliding window is shown; however, it is well known that there are usually two or more of these units 60 mounted in such a frame. The glass panel structure includes a self-contained unit 64 with glass panes 66, 68 and spacer 70 of identical construction to the glass pane unit 22 shown in Fig. 1. A series of border elements 72 peripherally extending about the outer marginal edges of glass panes 66, 68. The border elements 72 are made of the same material as border elements 34 of Fig. 1; however, in the present example, each element is U-shaped with two upstanding side portions 74, 76 interconnected by means of web portion 78.The inner faces of the upstanding arm portions of the border elements are provided with a series of parallel longitudinal ridge projections which serve to grasp the marginal edges of the glass panes 66, 68. In covering arrangement over the border elements 72 is a series of metallic members 82, again formed of two sections 84, 86 interconnected by means of a rigid insulating material 88 similar to material 50 of Fig. 1. Each metallic member has two upstanding portions 90, 92 in engagement with the outer face of side portions 74, 76 of the border elements. In this embodiment, the inner faces of the metallic members and the outer faces of the border elements have cooperative longitudinal ridges and grooves which tightly engage one another. Hence, in this embodiment, the engagement and disengagement of a metallic member to and from its associated border element is effected by a lengthwise sliding movement of the metallic member relative to the border element.
Referring to Fig. 3, there is shown another embodiment of the present invention which in this case could be the two jamb portions of the sliding window or door of Fig. 2. Border elements 100 are sealingly attached to a glass pane unit 101, similar to units 22 and 64 of Figs. 1 and 2, respectively. In this case, the border elements 100 have a U-shape with a web portion 102 and two side portions 104, 106, the side portions being sealed to the outer marginal edges of the glass panes by means of a sealant 108 similar to sealant 39 of Fig. 1. In covering engagement with the border elements 100 are metallic members 110 which are formed of two sections 116,188 interconnected by means of an insulating material 120, similar to elements 50 and 88 of Figures. 1 and 2, respectively. In this embodiment, the insulated metallic sections 116,118 have, at each extremity thereof, inwardly turned flanges 122, 124 which are respectively engagedly received in correspondingly shaped grooves extending in the upper portions 126, 128 of each border element.
In the embodiment illustrated in Fig. 3, the removal of a metallic member from its border element is similar to that in Fig. 2, i.e. by a lengthwise sliding movement.
It will be evident that there are many configurations which can be given to metallic member or to its means of engagement to the border element sealingly attached to the glass panes unit. It is therefore wished to have it understood, that the present invention should not be limited in interpretation except by terms of the following claims.
