Abstract
Hinges between panels of an overhead door for an opening of industrial premises are defined by configurations (6,7, 14) which form integral parts of the panel edges, if desired in conjunction with inserted auxiliary members (15).
The panel edges may be defined by rigid aluminium extrusions (1,2) and these may have parallel slots to receive and retain panel facing sheets (18,19). Thermally insulating material (21) may be packed between the facing sheets.
Description
- This invention relates to a closure structure of the kind, hereinafter referred to as the kind described, which has a plurality of panels joined in edge-to-edge disposition by hinges and which, in use, is movable across an opening, such as a doorway of industrial premises, towards and away from a closed position at which the opening is covered by the structure, the hinges permitting flexing of the structure during such movement to accommodate, for example, negotiation of a curved path.
- With a known closure structure of the kind described which is an overhead door, opposite ends of the panels have rollers thereat which run in tracks having straight portions extending substantially vertically at opposite sides of the opening and linking via curved portions with straight substantially horizontally extending overhead portions. With this arrangement'it is known to join each pair of adjacent panels with a number of separate hinges which are individually riveted to the panel edges. This involves however time-consuming and expensive manufacturing procedures and an object of the present invention is to provide a hinge joint for a closure structure of the kind described which can be assembled in a simpler and more convenient manner.
- According to the invention therefore there is provided a closure structure of the kind described wherein the hinges joining the panels are defined at least partially by configurations extending longitudinally and constituting integral parts of the panel edges.
- With this arrangement it will be appreciated that multiple riveting operations can be obviated whereby it is possible to effect assembly of the hinge joints of the closure structure in a simple convenient and inexpensive manner.
- Most preferably, the panel edges are defined by elongate rigid members, particularly extruded aluminium sections, and these are adapted to support and retain one or more plates or sheets, such as aluminium facing sheets. Such elongate members may extend wholly or substantially wholly across the panels between opposite ends thereof and may be shaped such that the members of adjacent panel edges have complementary configurations and interfit with each other to define the pertaining hinge joint. Alternatively, an auxiliary elongate element may be provided which in combination with the members of the adjacent panel edges forms an arrangement of complementary configurations which interfit to define the hinge joint. Such element may be secured as by screws or the like to one such member and may comprise for example a D-section hollow structure.
- Said members may have a slot or slots therein to receive at least one sheet or plate as aforesaid. Preferably the arrangement is such that a pair of sheets can be mounted in spaced-apart parallel disposition in each panel and the space between the sheets may be filled with a rigid plastics foam material (preferably formed in situ) to impart structural strength and also good thermal insulation properties. Also with a view to providing good thermal insulation properties, a sealing member may be provided between abutting surfaces of adjacent panel edges, and the said elongate members may have barrier portions which are formed to restrict thermal conductivity through the members without unduly adversely affecting the structural strength thereof.
- The closure structure of the invention may take any suitable form and may be used for any suitable purpose although it is anticipated that it will find particular application as an overhead door for industrial premises as hereinbefore described.
- The invention will now be described further by way of example only and with reference to the accompanying drawings in which:-
- Fig. 1 is a sectional view of one form of a closure structure according to the invention;
- Fig. 2 is a diagrammatic perspective view of one panel of the structure of Fig. 1 together with an associated track as used therewith;
- Fig. 3 is a sectional view showing a modification of the arrangement of Fig. 1.
- The closure structure is an overhead door as used in a doorway of industrial premises and. comprises a plurality of panels of rectangular form each having the two long edges thereof defined by extruded alum- . inium sections 1, 2..
- As shown in Fig. 1, the section 1 at the top edge of each panel is in the form of a channel having a
bottom wall 3 and two side walls 4 withslots 5 therein. Thebottom wall 3 has an integral flange 6 on its outer face and the flange 6 and thebottom wall 3 are shaped to define an elongate part-cylindrical socket 7 extending throughout substantially the entire length of the panel between opposite short end edges thereof. The opening of the socket 7 is on the inside of the panel (i.e. it faces towards the inside of the industrial premises). Between the socket 7 and the outside of the panel there'is a barrier section 8 on the inner face of thewall 3, that is a section providing a long narrow path and therefore poor thermal conductivity between the inside and the outside of the member 1. On the outer face of thebottom wall 3 there is a groove at the location of the barrier section 8 and aneoprene insert 9 is retained therein. - The section 2 at the bottom end of each panel (except the bottom panel as described later) is also in the form of a channel having two
side walls 10 withslots 11 therein and ashaped bottom wall 12. Thebottom wall 12 contains on its inner face abarrier section 13 like the section 8 and on the outer face of thebottom wall 12 at the inner side of the member 2 there is a projectingflange 14. - The socket 7 of each member contains a D-
section aluminium extrusion 15 which is of complementary configuration to the socket 7 and is free to swivel therein, and theflat face 16 of thisextrusion 15 is fixed byscrews 17 to theflange 14 of the adjacent member 2. In this way a hinge joint is defined between the long edges of adjacent panels. It will be noted that thebottom wall 12 of each member 2 is shaped to provide a longitudinally extending recess or channel to receive the flange 6 of the associated member 1 whilst permitting engagement of an adjacent flat portion of thewall 12 of the member 2 with theinsert 9 of such member 1. - Each panel has two
plates slots plates channel sections 20 is filled by injection with a rigidplastics foam material 21 which imparts structural rigidity and also thermal insulating properties to the panel. Thechannel sections 20 may be of similar construction to the sections 1 and 2 in that they have bottom walls, slotted side walls and barrier sections, although the bottom walls thereof are flat (i.e. they have no projecting flanges or recesses or inserts). - The top section of the top panel may be of like construction to the
sections 20 rather than the sections 1. - The bottom panel of the closure structure, as shown in Fig. 1, has at the bottom edge thereof, an
aluminium extrusion 22 which is similar to the bottom extrusions 2 in that it is in the form of a channel having abottom wall 23, slotted side walls 23a and a barrier section 23b but, on the outer face of thebottom wall 23, there is a groove 24 in which is mounted a flange of a resilient rubber orplastics tube 25. - At the opposite short ends of each panel,
rollers 26 are secured to the ends of the top sections 1 and project from the panel for engagement withtracks 27 which run vertically at opposite sides of the door opening and link viacurved portions 28 with overhead horizontal portions 29 (only the track at one side is shown in Fig. 2). - A
drive mechanism 30 of suitable form, for example a motor-driven drum above the doorway around which is wrapped acable 31 connected to the bottom edge of the bottom panel, is provided to effect powered lifting of the door from a closed position at which the door is located between the vertical portions of thetrack 27 and covers the doorway, and an open position at which the door is located between thehorizontal portions 29 of thetrack 27 and the doorway is not covered. Provision may be made for ready upward movement of the door by hand as for example by using a spring or the like to counterbalance the weight of the door; and the door may be movable from the open position to the closed position by hand and/or by reverse powered action of thedrive mechanism 30 as desired. - With the embodiment described the hinge, joints between the panels can be manufactured and assembled in a particularly simple, convenient and inexpensive manner. It is not necessary to perform multiple riveting or other time-consuming fixing operations: the D-
section elements 15 are simply inserted into the sockets 7, adjacent members 1, 2 are interengaged with each other, and theflanges 14 are screwed to theelements 15. Advantageously, theelements 15 can be inserted into the sockets 7 through the open longitudinal sides thereof with the elements at 900 to the position shown in Fig. 3, such elements then being rotated axially through 900 to complete the insertion. Thus, it is not necessary to have access to the ends of the sockets 7 and this facilitates assembly, particularly in the case where, for example, a damaged panel is to be replaced in situ'on an installed door. - Further, the resulting door structure can ensure good protection against heat loss through the doorway. This protection arises as a consequence of the
thermal insulation material 21 between thesheets sections 8, 13 due to theinserts 9 which effect sealing between adjacent panels, and due to thetube 25 which engages the ground surface at the bottom of the doorway and seals the door relative thereto. - It is of course to be understood that the invention is not intended to be restricted to the details of the above embodiment which are described by way of example only.
- Thus, for example, if desired the barrier sections may be omitted from all channel sections and, as shown in Fig. 3, the
bottom walls 12 of the sections 2 may be shaped to provide curved rather than angular recesses, and theinserts 9 may be omitted from the sections 1. Thetube 25 on the bottom section may be particularly advantageous in the case of electrically operated doors in so far as the interior of the tube can be used as a pneumatic actuator for a safety switch which reverses the downward movement of the door in the event that the tube engages and is compressed by a person or object trapped beneath the door. In this case a limit switch would be provided to de-actuate the safety switch when the door is at its normal limit of downward motion and the tube engages the ground surface. - Where the door is manually operated, or in the case where the
tube 25 is not required for use to actuate a safety switch, it may be preferable to use a pair of (inboard and outboard) rubber or plastics skirts for sealing engagement with the ground surface. Such skirts may have beads at their top edges which are inserted into so as to be retained within circular or other cross-section grooves set into the base of thesection 23. Conveniently, thebottom section 23 may be provided with the groove 24 centrally thereof and the above-mentioned bead-receiving grooves may be provided on opposite sides of this groove, whereby thesection 23 can then be used with either kind of sealing arrangement as desired.
