Description
This invention relates to a weatherproof double door structure~ and an enclosure embodyinq such a structure. Particularly the invention is applicahle to housings and enclosures containinq equipment such as telecommunications equipment and similar electrical equipment.
nut~oor enclosures, particularly for electrical and electronic e~uiPment, need to be sealed against the environment9 when closed. ~lso, the enclosure should he resistant to vandalism. With larqe enclosures having double doors and no central vertical bar, providing a complete seal all round the periphery of the doors is extrernely difficult, particularly preventing ingress of water.
~utters can be formed alonq the top of the enclosure, with cooperatinq formations on the tops of -the doors. Anv water entering hetween th~ top of a door and the top of the enclosure is caused to fall into the qutter. However, the over'lapping of the doors to prevent ingress of water hetween the dools, prevents the formation of a continuous gutter a'lonq the top of the enclosure, and along the bottom, Normally the gutter is cut, leaving a qap into which the door edge formations fit, and some attempt is made to prevent water leakin~ through the gap between the glltter end and door edges. This is usually not fully effective.
The present invention provides an arrangement which qives overlappinq interengaqing formations at the mating edges of the doors and also a continuous gutter along the top edge, and also the hottom edge if desired. There is provided a continuous channel at matinq edqes of the doors and along the top, and bottom, so that water enterinq between the edges of the doors and between the tops of the doors and the enclosure, can drain away along the channels.
Similarly a channel along the bottom drains away water entering hetween the ~ottoms of the doors and the enclosure. Channels also extend down the sides of the enclosure for draina~e of water entering between the hinqed edges of the doors and the enclosure and also to provide a drainaqe path for water in the top channel. Gaskets are provided for sealing inward of the channels. In enclosures having access to back and front, with douhle doors, the drainaqe is provided hack and Front, and also the gasket sealing.
In A double door structure comprises a continuous channel along the top of a door opening of an enclosure, the channel having an open side facing towards the outside of the enclosure, the open si-le having a low wall extendinq the length of the channel; a channel at the inner edtle of a first door, the channel having an open si(le facing outward, the channel extending inward from the doors outer surface, the door also having an inturned upper edge; a second door having an inturned inner edge and inturned upper edge, the inturned inner edge entering the inner edge channel of the first door; a U-shaped recess extending into the inner edge channel of the ~n first door, from an inner surface, the recess aclmitting the low wall of the continuous channel along the top of the door opening on closinq of the first door; and a U-shaped slot in the inturned inner edqe of the second door, the slot fitting over the U-shaped recess in the inner edqe channel of the first door, on closing of the second door .
The channel formed along the top of the door opening can extend all round the door opening, with si~ilar interengaging recess and slot at the bottoms of the inner edqes of the doors~
~Jaskets can provide a positive seal between the low wall of the channel around the door opening and the doors, and Further gaskets provided at the interenga~inn recesses and slots -to provide positive sealinq at these rlositions. A qasket in the bottom of the channel at the inner edge of the first door provides positive sealing with the inturned inner edqe of the second door.
There is thus provided a controlled leakage or drainage path for water all round the doors, backed up by a positive seal.
1n The channel fnrmations and inturned edges provide very effective resistance to vandalism.
The invention will be readily understood by the following description of a particular embodiment, by way of example, in con~junction with the accompanyinq drawings, in which:-Ficiure 1 illustra-tes diagramatically the interengaqing top channel, first door channel and recess and second door inner edge and slot;

Figures 13 and 14 are enlarged front and side recesses of the latch, as illustrated in Fi~ures 5 and 6 in greater detail.
Figure 1 illustrates, in a very general and diagrammatic manner, the basic features of the invention. The area illustrated ~ the top center of a housing with the top inner corners of the doc,rs and the channel at the top of Ihe door opening. The area illustrated is as seen from the inside. In the Figure, at the left is the channel a-t the top of the door openin~, indicated lenerally at 10~ Surface 11 is the outer surface wh~ch surrounds the door opening, the channel formed by the walls 12, 13 and 14. The open side, at 15, has a low front wall 16. The cross-section of the channel is also seen in Figure 7~
The top inner edge of a first door 17 is indicated ~enerally at 18, havincl a U-shaped channel defined by walls 19, 20 and 21. The channel extends inward from the outer surface of the door 17 and has an open side 22 facing outwards. The door also has an inturnecl top edge 23. The door pivots on hinges at the side remote from that shown, as indicated by the arrows 25. To enable the door to close wi~h the upper part of wall 2n adjacent to the rear wall 13 of the toP channel 1n, a recess 26 is formed in the channel at the inner edge of the door 17, the recess being U-shaped, re-entrant into the door edqe channel. The recess 26 is positioned a distance down from the top of the doorS that the bottom wall 27 of the recess passes ~Inder the hottom wall 14 o~ the top channel 3 the top part of wall 2Q entering through the open side of the ~eet~Y.
The low front wall abuts -the rear wall 28 of the recess, which, dS
explaine-l in more detail later, has qasket material thereon, but not indicated in Fiqure 1.
3y this structure, the first door can be closed and still permits of an unbroken top channel. The second door, 30, has an inturned top ed~e 31 and an inturned inner edge 32. At a distance down from the top edge 31, generally equal to the positioning of the recess 26 in -the door 17, a slot 33 is formed in the inturned inner edge 32, The slot is of such dimensions thclt it passes over the recess 2fi in door 17. The edge 3~ of the wall 21 of the first door 17 abuts the inner surface of the second door 30, on which there a tlasket can be placed, not indicated in Figure 1. The inner edge 32 of door 3n can also be turned in, at 35 and arranged to abut wall 20 of door 17. Atlain a ~asket can be positioned on the inner surfac~ of wall 20.
Thus Fiqure 1 illustrates the general principle of the invention, whereby it is possible to provide a continuous channel~ or gutter, 10 and at the same time have two doors close, withollt cutting the channel. The doors are closed sequentially and complete closure is obtained against water without a central post.
7~
~!ater enterinq hetween the top of either door and the enclosure framinq the door will finish uP in ~he channel. At the closure position between the two doors, the water will run down to the top of recess 2fi forward and down the rear wall 2~ of the recess, and then skraiqht down the channel at the inner edge of the first door 17 to the bottom. ~ similar structure can be provided at the bottom, the arranqement inverted with a channel along the bottom of the door openinq. The water running down the inner edge channel will drain into this channel 9 as will water entering between the bottom edge of 1n either door and the hottom enclosure framing.
Fiqure 2 is a front view of an enclosure 40, with two doors, correspondinq to doors 17 and 30 of Figure 1. In many cases access to fhe rear is also required and in such cases two cloors are also provicled at the rear. The rear view would then be the same as the front view of Figure 2. A latchinq handle 41 is provicletl which actuates latches at top ancl hottom, and also in the middle, to exert a positive ~ressure aqainst a seal. The latches are describe(l later with respeck ~o Fi~ures 13 and 1~.
Fiqures 3 and 4 illustrate the inner surface or side of 2n the first door 17 and an end view on khe inner edge of the first door 1~ respectively. Recesses 2fi are showr, at top and bottom and also shown is a qasket ~2 which exkends alonq near the top and bottom of the door and near the hin~e edge of the door. The qasket provides a seal aqainst the low wall 16 of channels at top and bottom of the enclosure. A similar channel is provided down each side of the enclosure, hoth front ancl back if doors are in front and hack, and 4~-the side section of qasket~A1 seals against a similar low wall on the channel at the side. A typical gasket ~aterial is a neoprene rubber.
An inturned edqe can he provided at the hinged edge of the door, the inturned edqe entering the channel down the side of the enclosure or door opening. ~ short lenqth of gasket is applied to the rear wall 28 of the recess 26, at 43. A typical thickness for the gasket ~3 on wall 28 is .25" while the typical thickness for gasket 42 is .5".
This is to provide a com~on level surface of gasket 42 and gasket sections 43. This is illustrated in more detail in Figures 8 and 9.
Top and bottom latches 44, recessing in guides 46, are shown in 1n Figures 3 and 4. The latches 44 are connected by, in the exa~ple, a nylon rope 45, and are biased to a latched position by compression springs in the guides 46. The ends of the latches 44 engage behind the wall 13 of the channel at top and bottom and can have inclined ends to give a wedqing action to force the door edges against the gaskets. ~nce door 30 is open, door 17 can be opened by pulling on the rope 45.
Figures 5 and 6 are similar views of the second door 30, as Fi~ures 3 and ~ of door 17. The slots 33 are seen in F-igure 6, A sealing gasket extends round near the periphery of the door, comprised oF two sections. A first section 50 extends up near the inner edqe of the door, positioned for contact with the edge of the wall 21 of the channel formed at the inner edge of door 17, this edge of the wall identified at 34 in Figure 1. A second section 52 extends alon~ the top, down the hinqe side and along the bottom. In the exa~ple illustrated, the thickness of section 5n is .25" and the thickness of section 52 is .5". The end surface 51 of sections 52 abuts aqainst the end surface 54 of gasket 43. Section 52 is 3~7~
contacted hy the low wall 16 of -the channel which extends along the top of the ~oor openinq and also down the sides and alonq the bottom.
The two sections ~0 and 5~, at the top inner corner of the door, are illustrated in Fiqures 10 and 11. Again a typical material is neoprene rubher. As with door 17, an inturned edqe can be provided at the hinqed edge of the door, the inturned edc~e entering the channel down the side of the enclosure or door openinq.
Figure 12 is an illustration of a corner of a gasket, for example the top corner at the hinge side. The gasket material, 1n normally in strip form, is notched and bent round to form a corner ~3. A similar arranqement is used at other corners, such as with qasket 42, in Fiqure 3.
Conveniently, the enclosure 40 has a channel formation all rouncl the door openinq. When access is required at both back and front, a door o~eninq is provided in back an(i front, two doors in each oPeninq. Roth sets of doors9 and the surroundinq openintl are of the same form of structure, as illustrated in Figure 1 particularly.
Fiqure 7 illustrates channels at both front and back.
The overlappin~ structure, hetween the doors and the ~n enclosure at top, hottom and hinged sides of the doors, and the overlappinq structure at the mating door edges, in addition to providinq a closely controlled path for water, also is very ef-fective against vandalism. Ik is extremely difficult to get any form of bar or tool between door and frame, or between matin~ ed~es of doors, due to the channel at the edge of the door opening, and to the channel on one door edqe. In addition, should the inner walls be forced in, these will tend to interlock, thus hindering entry.
Fiqures 13 and 14 illustrate in more detail the latches and associated handle on cloor 30. The handle 41 is pivotally mounted on the front o-f the door 30, b,y means of a plate 60 attached by screws hl, A shaft 62 extends inward from the handle 41 and carries a flat Plate-like lever fi3 which has a tongue portion 64 extending towards the cloor edge 32 when the handle is in a latching position~
that is with the handle extencling downward as in Figures 2 and 14.
The pivotal axis of handle 41 and lever 63 is indicated at 65 in Fi~ure 13~ To the top and bottom of the lever 63, on the side of 1n axis h5 remote from the tonque 6~, two rods 66 and 67 are pivotally attached. Rod 6h extends upward and rod 67 downward.
At the ends of rods 66 and 67 remote from the lever 63 are attachecl rollers 6~, the rollers carriecl in brackets fi9 formed on or attached to the ends of the rods. The assembly of lever 63 rods hh~ 67 and rollers 6~ is also illustrated in Figure 5. The rollers h8 are arranqed to be in engagement with the inner surface of the wall 13 of the channel surroun(iin-l the door openinq. The rods h6 and 67 are hiased so as to produce a c'losing force on the door 30, and thus also on door 17 as the handle 41 is turned to a latched 2n position, the rollers rollinq up onto the wall 13. This closing Force forces the various door edges into firm contact with the ~askets 42, 43, 50, 52. The rods 66 and 67 can run in guides attached to the inner surface of the door 30. The tongue 64 engages hehind the wall 20 of the door 17.
A bracket 70 can he formed on the plate 60, extending outward and a 'luq 71 can extend inward from the handle 41. Holes in the bracket 7n and luq 71 provide for insertion of a padlock to lock the handle 4l in a latched position.
nut~oor enclosures, particularly for electrical and electronic e~uiPment, need to be sealed against the environment9 when closed. ~lso, the enclosure should he resistant to vandalism. With larqe enclosures having double doors and no central vertical bar, providing a complete seal all round the periphery of the doors is extrernely difficult, particularly preventing ingress of water.
~utters can be formed alonq the top of the enclosure, with cooperatinq formations on the tops of -the doors. Anv water entering hetween th~ top of a door and the top of the enclosure is caused to fall into the qutter. However, the over'lapping of the doors to prevent ingress of water hetween the dools, prevents the formation of a continuous gutter a'lonq the top of the enclosure, and along the bottom, Normally the gutter is cut, leaving a qap into which the door edge formations fit, and some attempt is made to prevent water leakin~ through the gap between the glltter end and door edges. This is usually not fully effective.
The present invention provides an arrangement which qives overlappinq interengaqing formations at the mating edges of the doors and also a continuous gutter along the top edge, and also the hottom edge if desired. There is provided a continuous channel at matinq edqes of the doors and along the top, and bottom, so that water enterinq between the edges of the doors and between the tops of the doors and the enclosure, can drain away along the channels.
Similarly a channel along the bottom drains away water entering hetween the ~ottoms of the doors and the enclosure. Channels also extend down the sides of the enclosure for draina~e of water entering between the hinqed edges of the doors and the enclosure and also to provide a drainaqe path for water in the top channel. Gaskets are provided for sealing inward of the channels. In enclosures having access to back and front, with douhle doors, the drainaqe is provided hack and Front, and also the gasket sealing.
In A double door structure comprises a continuous channel along the top of a door opening of an enclosure, the channel having an open side facing towards the outside of the enclosure, the open si-le having a low wall extendinq the length of the channel; a channel at the inner edtle of a first door, the channel having an open si(le facing outward, the channel extending inward from the doors outer surface, the door also having an inturned upper edge; a second door having an inturned inner edge and inturned upper edge, the inturned inner edge entering the inner edge channel of the first door; a U-shaped recess extending into the inner edge channel of the ~n first door, from an inner surface, the recess aclmitting the low wall of the continuous channel along the top of the door opening on closinq of the first door; and a U-shaped slot in the inturned inner edqe of the second door, the slot fitting over the U-shaped recess in the inner edqe channel of the first door, on closing of the second door .
The channel formed along the top of the door opening can extend all round the door opening, with si~ilar interengaging recess and slot at the bottoms of the inner edqes of the doors~
~Jaskets can provide a positive seal between the low wall of the channel around the door opening and the doors, and Further gaskets provided at the interenga~inn recesses and slots -to provide positive sealinq at these rlositions.

Figure 1 illustrates, in a very general and diagrammatic manner, the basic features of the invention. The area illustrated ~ the top center of a housing with the top inner corners of the doc,rs and the channel at the top of Ihe door opening. The area illustrated is as seen from the inside. In the Figure, at the left is the channel a-t the top of the door openin~, indicated lenerally at 10~ Surface 11 is the outer surface wh~ch surrounds the door opening, the channel formed by the walls 12, 13 and 14. The open side, at 15, has a low front wall 16. The cross-section of the channel is also seen in Figure 7~
The top inner edge of a first door 17 is indicated ~enerally at 18, havincl a U-shaped channel defined by walls 19, 20 and 21. The channel extends inward from the outer surface of the door 17 and has an open side 22 facing outwards. The door also has an inturnecl top edge 23. The door pivots on hinges at the side remote from that shown, as indicated by the arrows 25. To enable the door to close wi~h the upper part of wall 2n adjacent to the rear wall 13 of the toP channel 1n, a recess 26 is formed in the channel at the inner edge of the door 17, the recess being U-shaped, re-entrant into the door edqe channel. The recess 26 is positioned a distance down from the top of the doorS that the bottom wall 27 of the recess passes ~Inder the hottom wall 14 o~ the top channel 3 the top part of wall 2Q entering through the open side of the ~eet~Y.
The low front wall abuts -the rear wall 28 of the recess, which, dS
explaine-l in more detail later, has qasket material thereon, but not indicated in Fiqure 1.
3y this structure, the first door can be closed and still permits of an unbroken top channel. The second door, 30, has an inturned top ed~e 31 and an inturned inner edge 32. At a distance down from the top edge 31, generally equal to the positioning of the recess 26 in -the door 17, a slot 33 is formed in the inturned inner edge 32, The slot is of such dimensions thclt it passes over the recess 2fi in door 17. The edge 3~ of the wall 21 of the first door 17 abuts the inner surface of the second door 30, on which there a tlasket can be placed, not indicated in Figure 1. The inner edge 32 of door 3n can also be turned in, at 35 and arranged to abut wall 20 of door 17. Atlain a ~asket can be positioned on the inner surfac~ of wall 20.
Thus Fiqure 1 illustrates the general principle of the invention, whereby it is possible to provide a continuous channel~ or gutter, 10 and at the same time have two doors close, withollt cutting the channel. The doors are closed sequentially and complete closure is obtained against water without a central post.

The qasket provides a seal aqainst the low wall 16 of channels at top and bottom of the enclosure. A similar channel is provided down each side of the enclosure, hoth front ancl back if doors are in front and hack, and 4~-the side section of qasket~A1 seals against a similar low wall on the channel at the side.

Conveniently, the enclosure 40 has a channel formation all rouncl the door openinq. When access is required at both back and front, a door o~eninq is provided in back an(i front, two doors in each oPeninq. Roth sets of doors9 and the surroundinq openintl are of the same form of structure, as illustrated in Figure 1 particularly.
Fiqure 7 illustrates channels at both front and back.
The overlappin~ structure, hetween the doors and the ~n enclosure at top, hottom and hinged sides of the doors, and the overlappinq structure at the mating door edges, in addition to providinq a closely controlled path for water, also is very ef-fective against vandalism. Ik is extremely difficult to get any form of bar or tool between door and frame, or between matin~ ed~es of doors, due to the channel at the edge of the door opening, and to the channel on one door edqe. In addition, should the inner walls be forced in, these will tend to interlock, thus hindering entry.
Fiqures 13 and 14 illustrate in more detail the latches and associated handle on cloor 30. The handle 41 is pivotally mounted on the front o-f the door 30, b,y means of a plate 60 attached by screws hl, A shaft 62 extends inward from the handle 41 and carries a flat Plate-like lever fi3 which has a tongue portion 64 extending towards the cloor edge 32 when the handle is in a latching position~
that is with the handle extencling downward as in Figures 2 and 14.
The pivotal axis of handle 41 and lever 63 is indicated at 65 in Fi~ure 13~ To the top and bottom of the lever 63, on the side of 1n axis h5 remote from the tonque 6~, two rods 66 and 67 are pivotally attached. Rod 6h extends upward and rod 67 downward.
At the ends of rods 66 and 67 remote from the lever 63 are attachecl rollers 6~, the rollers carriecl in brackets fi9 formed on or attached to the ends of the rods. The assembly of lever 63 rods hh~ 67 and rollers 6~ is also illustrated in Figure 5. The rollers h8 are arranqed to be in engagement with the inner surface of the wall 13 of the channel surroun(iin-l the door openinq. The rods h6 and 67 are hiased so as to produce a c'losing force on the door 30, and thus also on door 17 as the handle 41 is turned to a latched 2n position, the rollers rollinq up onto the wall 13. This closing Force forces the various door edges into firm contact with the ~askets 42, 43, 50, 52. The rods 66 and 67 can run in guides attached to the inner surface of the door 30. The tongue 64 engages hehind the wall 20 of the door 17.
A bracket 70 can he formed on the plate 60, extending outward and a 'luq 71 can extend inward from the handle 41. Holes in the bracket 7n and luq 71 provide for insertion of a padlock to lock the handle 4l in a latched position.
