Abstract
ABSTRACT OF THE DISCLOSURE
A folding barrier assembly has a guide track and floor structure comprising an elongated member of sheet material having a channel-shaped cross-section received and embedded within a floor. The guide track has a central basewall forming the bottom of the track and divergent sidewalls extending upwardly and outwardly from opposite side of the basewall. The sidewalls at the upper ends thereof merge into reversely bent downwardly and outwardly inclined and divergent securing flanges of which are fully embedded within the floor to anchor the track, the channel being upwardly open relation to receive the folding barrier therein. The securing flanges provide secure anchoring means embedded within the floor for extended service life of the guide track, the folding barrier being engaged with and slidable longitudinally of the guide track.

Description
~2;~7~3 This invention relates to a guide track for a folding barrier, such as a folding door comprising a plurality of vertically arranged pickets mounted for sliding movement transversely of the door opening and a plurality of door leaves hinged to such pickets and to each other. In addition such folding door conventionally is provided with a lattice structure extending between the door pickets and slid ably engaged therewith to slide in a direction longitudinally thereof. Conventionally also such a door is supported from the door frame structure so as to depend therefrom and the bottom ox such a door is guided in a guide track extending along the floor between the vertical members of the door frame. Such a guide track is generally of channel formation.
In many cases it is required -that vehicles and/or heavy equipment pass through a doorway to which such a door as described above is fitted. To facilitate such passage it is known -to dispose the channel-shaped guide track in a channel provided in the floor, thereby avoiding any step formation over which the vehicle or equipment must pass. Although such an arrangement is satisfactory in certain applications, in other applications particularly in the case of large and heavy doors and when large vehicles and/or very large, heavy equipment passes through a doorway at frequent intervals, the simple location of a guide track in a channel in the floor is inadequate. In such cases the loadings to which the track and surrounding floor are subjected by the door itself and by the vehicles and/or equipment can cause the guide track to become damaged and thereby loose and/or displaced from the channel in the floor. The provision of converttional fixing means such as bolts can interfere with the smooth and proper operation of the door.
It is an object of the present invention to provide a folding barrier which avoids or reduces to a substantial extent the disadvantages referred to above.
The inventiorl provides a folding barrier assembly including, a guide track and Floor structure comprising an elongate member of sheet material having an upwardly open chantlel-sh~ped cross-section received and embedded within a floor and a folding barrier having portions engaged with and slid able longitudinally of the guide track for controlling access to an area of the floor, the guide track including a central baseball forming the bottom of the track, and a pair of sidewalls lo extending upwardly and outwardly from respective sides of the baseball, the sidewalls diverging with respect to each other at a small angle to -the vertical for receiving therein and laterally confining -the portions of the folding barrier, the sidewalls at upper ends thereof merging respectively into reversely bent downwardly and outwardly inclined securing flanges extending longitudinally along the sidewalls and diverging with respect to each other along the length thereof, the entireties of the securing flanges from tile junctures with the sidewalls being fully embedded within the floor to anchor the track, and the diverging sidewalls providing clearance for the folding barrier portions while the diverging securing flanges provide secure anchoring means embedded within the floor for extended service life of the guide track.
Preferably, each securing flange terminates in a reversely curved upwardly and outwardly directed terminal lip along the length thereof. Each of said lips may extend in a direction away from the baseball and the sidewalls, and may be inclined to the respective securing flange at an external angle owe between 60 and 180, preferably between 130 and 140.
In a preferred embodiment, the junctures between the sidewalls and the securing flanges lie substantially I,, I' ~7~3 yin the laurel of the floor within which the guide track is embedded, and each securing melange is inclined at an angle of between lo and 80 to the respective sidewall.
Said sidewalls may diverge in a direction away from said baseball and may diverge at an included angle of between 3 and 15. Preferably said sidewalls are of substantially equal height.
The guide track may be of metal, for example mild steel and may have a protective treatment applied thereto, for example galvanizing.
The barrier may include a plurality of vertically arranged pickets mounted for sliding movement within the channel defined by the baseball and diverging sidewalls, a plurality of door leaves hinged to the pickets, and to each other, and a lattice structure extending between the pickets and slid ably engaged therewith whereby the pickets, leaves and lattice structure define a folding barrier movable in the guide track.
on embodiment owe the invention will now be further described with reference to the accompanying drawing, in which:-Figure 1 is a scrap perspective view, partly in section owe a guide track and folding door assembly, and Figure 2 is an enlarged cross-section of the guide track of Figure 1.
Referring now to the figures there is shown a folding door assembly 10 comprising a vertically disposed picket 11 and leaves 12 hingedly secured therein. Lattice bars 13 are slid ably secured to the picket 11 by means of a bolt 14 whose head is slid ably retained in a channel formation I of the picket 11.
The door structure 10 is supported at the top thereof by the door frame structure (not shown) and the bottom ends of the pickets 11 are guided in guide track 16. The guide track 16 is located in a recess 17 in the floor 18 so that it does not protrude above the floor :
I, surface lo. In coonskins, vehicles nor heavy equipment may readily pass through the doorway without having to rise up over the guide track 16, thereby reducing the risk of damage to the vehicle, equipment or S guide track 16.
The guide track 16 comprises a baseball 20 and two sidewalls 21 upstanding therefrom to form a channel 22 in which the bottom ends of pickets 11 are received. The sidewalls 21 diverge upwardly at an included ankle of approximately 7 so that only line contact occurs between the picket 11 and the sidewalls Al. By this means friction between the picket 11 and sidewalls 21 is minimized, thereby facilitating easy opening and closing ox the door structure 10.
The top edges 23 of sidewalls 21 are at the level of floor surface 19 and extending from each top edge 23 is a securing flange 24. The securing flange 24 is inclined at an angle of approximately 150 to the respective sidewall 21 and has a lip 25 at the edge 26 remote from that sidewall 21. The lips 25 extend at an angle of approximately 135 to the respective securing flange 24 and the edges 26 lie in the plane of baseball 20. The securing flanges 24 and the lips 25 are embedded in the floor I which may be for example of concrete, so that the floor material fills the spaces between the sidewalls Al and the securing flanges 24. This provides good support for the sidewalls 21 to resist deformation under loads applied thereto by misuse of the door, i.e.
under vehicular impact or the like. Since the lips 25 are effectively encased in the floor material, there is very high resistance to the guide track 16 being dislodged by such loads as aforementioned. Furthermore, the -top edges 23 of sidewalls 21 and securing flanges 24 provide a secure edge to the channel 22 which is resistant to damage by vehicles passing there over, providing protection for the concrete or the like which might otherwise chip or crumble in the region of the channel edge.
