Description
1 163~ 1 ~
This invention relates to a mullion member and an assembly and relates particularly to such for use in connection with adja-cent roller shutter doors in a doorway.
Hitherto in the roller shutter door art, which is also re-ferred to as the roller curtain door art, where two roller shutter doors are placed side by side it has been common practice to pro-vide a removable mullion member between the two roller shutter doors. A problem with such prior art mullions was that in order to fasten the mullion member to the floor and to the top of the door opening it was necessary to provide mounting bracket means which were held to the mullion member by bolts which pass through the outer face of the mullion member. The mounting bracket means, in turn, carried two fastening means which engaged respectively with the top and the bottom of the door opening. One or both of the fastening means was releasable so that the mullion could be re-moved. In the prior art the heads of the bolts are very unsightly on the front face of the mullion and additionally the fastening means is not entirely satisfactory.
Accordingly the present invention has been devised with the object of providing an improved mullion member whereby fastening can be made without boltheads or the like being visible from the outside of the door opening and whereby a better releasable con-nection can be made to the top and bottom of the door opening.
According to one aspect of the invention there is provided a mullion member for fitting between a pair of adjacent roller shut-ter or roller curtain doors in a door opening, the mullion member being of a suitable length and having opposed channels at opposite sides each for slidably receiving the edge of the curtain of a res-116331~

Figure 5 is a close-up detail of the mullion member and tongue means therein for engaging the one portion, and Figure 6 is a side cross-sectional view taken along the lines 6-6 of Figure 5.
Referring firstly to Figure 1 there is shown a door open-
3 -~ 1~3~ 1 4 ing 1 and a mullion member assembly 3 therebetween. Two roller shuttered doors 5 and 6 bridge the door opening 1. Door frame means 7 are provided on each side of the opening for slidably receiving the outer sides of the curtains of the roller shutter doors 5 and 6. The section of the mullion assembly 3 is shown in Figure 2 and comprises opposed channels 11 in which the edges of the curtains of the roller shuttered doors 5 and 6 are receiv-ed. The mullion member has a portion 13 bridging the two channels 11 and behind said portion 13 on the inside face of the mullion member are two flange means 15 which define a recess 17 between said flange means 15 and the bridging portion 13. The recess 17 receives a tongue member 19 so it can slide in a direction along the length of the mullion member in the recess 17. The tongue 19 will be referred to later. The flange means 15 extends substan-tially parallel with the outermost face of the mullion member.
The mullion member assembly 3 includes one piece 21 for fixing at the door opening 1 so as to extend downwardly from the top of the opening 1. The piece 21 can be of any desired length provided it has sufficiant length to enable its uppermost end to be fastened to frame means surrounding the opening 1 such as by bolts passing into brickwork or the like or alternatively by being boltèd directly onto the frame 7 which can be brought around to extend across the top of the opening 1. The other piece 23 of the mullion member assembly 3 is desirably made of a stand-ard length such as 7'6", which is the usual opening height of a doorway. The position of the one piece 21 is selected to be fastened so that the piece 23 can fit neatly thereunder and cen-trally between the doors6 and 6.

Referring now to Figures 3 and 4 there is shown a means whereby the lower end of piece 23 can be fastened to the floor.
A plate member 25 of the width equal to the width between the re-cess 17 and of a thickness e~ual to the depth of the recess 17 is screwed to the bottom of the piece 23 so that a portion 27 extends below the bottom of the piece 23. The plate 25 is screwed to the piece 23 by screws 29 which pass through the flanges 15 and screw into the plate 25. A further platle 31 is embedded into the floor and held thereto by bolts 33 in thle floor. The plate 31 has a slot 35 therein in which the portion 27 of the plate 25 can be received.
The tongue 19 which is slidably received in the recess 17 is made from a piece of steel plate of a width equal to the width between the channels 11 and of a thickness equal to the depth of the recess 17. The tongue 19 is fastened to a bolt 43 which is slidably retained to the piece 23 by a retaining member 45 which has a generally "top hat" sectional shape. The side flanges 47 o~
retaining member 45 locate underneath flanges 15 in the recess 17.
Screws 49 hold the retaining member 45 to the piece 23 by passing through the ~langes 15 and screw into the flanges 47. The bolt 43 has a handle 51 thereon for enabling manual movement of the tongue 19 up and down the recess 17 within limits defined by stops 53 and 55 provided in the position shown on the bolt 43 in Figures 5 and 6. The tongue 19 is in the extended position so that it extends past the top 57 of the piece 23. Thus by inspecting Figures 5 and 6 it can be seen that in this position the tongue 19 extends into the corresponding mating recess 17 in the piece 21 thus holding piece 23 in place between the two doors 5 and 6. The rearmost .
~ 1~3gl 4 flanges 61 which define part of the opposed channels 11 are cut, in the piece 21, at regions 63 and bent rearwardly as shown in Figure 6 so as to provide for a smooth entry of the curtain of the doors 5 and 6 into the channels 11.
Thus, to remove the piece 23 from between the doors 5 and 6, the doors 5 and 6 are both raised fully, bolt 43 is moved downwardly retracting the tongue 19 from the recess 17 in the piece 21. The piece 23 is then swung either forwardly or back-wardly and lifted so that the lower tongue 25 is removed from the slot 35 in the floor.
A mounting bracket 100 for mounting axle supports of the roller shutter doors 5 and 6 is fastened to the piece 21 at the required height. Two mounting brackets 100 may be provided one above the other if the heights of the roller shutter doors 5 and 6 are respectively at different floor heights. In each case the mounting brackets 100 may be of identical construction. The mounting brackets 100 comprise a plate member 101 which neatly slidably fits into the recess 17 so as it can slide longitudinalIy up and down the length of piece 21. The plate 101 has a right-angle arm 103 extending therefrom which is suitably braced bywebs 105. The arm 103 has a width which enables it to pass between the opposed channels 11 and between the flanges lS. It then sweils outwardly to a greater width at its free end to pro-vide a sufficient width for mounting of the axles thereto. The mounting bracket 100 is secured to the piece 21 by bolts 109 which pass through the flanges 15 and are screwed into the plate 101 .

A stop 110 for the roller shutter doors 5 and 6 is pro-vided on the piece 21. The stop 110 has buffers 111 at each side thereof which extend past the sides of the piece 21 so as to lo-cate with lugs 113 which are an integral part of the bottom of the roller shutter doors 5 and 6. The stop 110 is fitted to the piece 21 by an angle bracket 115 with a downturned rear portion 117. A bracket 115 connects with a plate 120 which in turn is of a size to be slidably received in the recess 17 in the same manner as the supporting bracket 100 and the tongue 19. The plate 120 is in turn fastened to the piece 21 by bolts 121 which pass through the flanges 15 and screw into the plate 120.
It will be appreciated that the front face 130 of the mullion member assembly 3 can have decorative grooves or pro-trudences moulded thereon. Desirably the pieces 21 and 23 are made from an extruded aluminium section.

A modification of the tongue 19' is shown in Figures 7 and 8.
The modified tongue 19' is slidably received in the re~
cess 17 and is made from a p~ece of metal such as aluminium or steel plate of a ~dth equal to t:he width ~etween the channels 11 and o~ a thickness su~stantially equal to the depth of the recess 17 so that it can slide therein along the length of the mull~on.
The tongue 19' has a stepped upper portion 31 of a width just narrower than the width between the sides o flanges 15 and it has a hand gripping portion 33 at its lower end. The portion 33 is made by ~ending a planar ~lank of the tongue 19' so that it extends at right angles from the plane of the major part of the tongue 1~'.
The tongue 19' also has a cut-out 35 at one side thereof.
The cut-out 35 ;~s marg~nally longer in length than the intended distance that the tongue 19~ is to extend past the end of the piece 23 and of a depth sufficient to hold a compression spring 37 therein. The compress~on spr~ng 37 bears against the upper end o~ the cut-out 35 at one end and against a retaining screw 39 screw thre~ded into the recess 17 t~rough one side of the channels 11 ~see Figs~ 2, 7 and 8) of piece 23. Thus the spring 37 acts by its bias t~ push the tongue 19 t outwaxdly from the end of the piece 23.

1163~4 the shoulders 41 of the stepped port;:on 31 are flush with the top of the piece 23 thus leaving the stepped portion 31 exposed.
Th.erefoxe, when in this positon the portion 31 is in the recesses 17 of piece 21 and can fie removed therefrom by merely swinging piece 23 away from piece 21, If t~e tongue 19' is released by an operator th.bn it will extend to the position shown in Figures 7 and 8 by the act~on of thb spring 37 and thus it will secure the piece 23 to piece 21 as the tongue 19' will then be positively located behind the flanges 15 o~ portion 21. .
~o ~t will be apprec.~ated that the mullion member described herei`n provides an easy "on site' installation as in the construction proposed here~n, if the door opening height is not precisel~ the` same as the mullion piece 23 (~ 7'6" -), then that piece 23 can be s~mply cut to the required length -preferably at the bottom ~ and the plate member 25 refitted. This does not require special tool~ or sk~lls by the installer.
Similarly, the exact locatin~ position of the mounting brackets 100 may be correctly positioned, on-site, so that the axles of each of the roller shutter doors are correctly positioned in height reIative to the floor and then the plate member 101 fastened at the correct position by the screws 109 passing through suita~le holes which may then ~e drilled on-site in the flange 15.
Further the stops 110 can ~e suitably positioned on-site by sliding the plate means 120 along the recess 17 to the required position and then the plate means 120 fastened to the flanges 15 by the screw~ 121 paSS~ng throuqh sui~able holes which may then be drilled ~n-s~te in the 1anges 15~
