DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD OF THE INVENTION
THIS INVENTION relates to mountings for movable members, and it has more particular reference to a mounting connection between two members whereby one may be moved relative to the other. In its broadest applications, the connection may embrace both the hinged connection of members and also the sliding movement of one member relative to the other.
BACKGROUND ART
There is described and illustrated in our co-pending Australian Patent Application No. 656,040 entitled "SLIDING DOOR AND WINDOW SECURITY MEANS" an emergency exit grille developed to provide easy escape from inside premises in the case of fire, opening of the sliding window in a sliding action causing the emergency grille to swing hingedly open automatically to allow the occupant to exit. It is naturally desired that the grille be able to swing open to adequate extent, and we have accordingly sought to develop improved hinges usable in this application. At the same time, we have come to realize the need for improved hinging actions in other applications, particularly where basic constructions make it difficult to obtain a hinging action through a full quarter-circle or through greater than ninety degrees. We have also discovered that components used in certain hinge arrangements which we are developing can be expected to prove useful in other mounting connections.
Accordingly, our invention has been devised with the principal object of providing such novel features in relation to mounting connections generally that our new concepts can be applied to either mounting connections having hinging features or to mounting connections in which one member (such as a panel) is slidable. Since our "EXIGRIL" (Registered Trade Mark) emergency exit of the aforementioned patent application involves a hinged escape panel on a sliding window, it will be appreciated that the components of this invention will be found particularly applicable thereto. Other objects and advantages of this invention will become apparent from the descriptions herein.
DISCLOSURE OF THE INVENTION
With the foregoing and other objects in view, the invention resides broadly, according to one aspect, in means for connecting two elongate members in parallelism and so that one may be moved relative to the other, said other member being adapted to be rigidly mounted and having a neck portion extending longitudinally and terminating laterally in a longitudinal bead engageable in a longitudinal groove of a longitudinal edge flange of said one or movable member, there being provided anti-friction contact strip means between said members, said strip means being substantially tubular or arcuate in cross-section with longitudinal alit means through which paid neck portion of said other member extends when the two members are connected, the parts being so made and arranged that said strip means may be fitted by end-wise longitudinal sliding into and along said groove and about and along said bead, and the two elongate members and interposed contact strip means are then restrained against separation by forces applied transversely thereof.
While the anti-friction contact strip means could be made up of a number of end to end strips, there is preferably provided a single length of anti-friction material having said longitudinal slit means in the form of a continuous slit throughout its length. Thus, the invention can be expressed according to another aspect as a mounting connection between two members whereby one may be moved relative to the other, comprising a first rigidly mounted member and a second or movable member connected thereto with an anti-friction contact strip therebetween of partial sleeve-like or tubular form, said strip having a longitudinal slit through which the said one member extends to its rigid mounting.
In that event, the mounting connection can be between a movable member and a fixed member, wherein the part sleeve-like anti-friction strip is continuous along a sliding rail, panel or the like constituting the movable member and it has frictiona
