Definitions
- the present invention concerns a sectional gate, in particular a gate comprising an articulated wall intended to extend substantially in vertical plane when said wall is in closed position.
- the panels of such sectional gate are mutually connected by means of articulating means which are also provided with roller means, which are meant to be guided by guide rails from a first position corresponding to the closed position of the sectional gate, to a second position corresponding to the open position of the sectional gate.
- the opening and closing of the gate is usually facilitated by an electric motor and/or a spring system.
- the spring system usually comprises a spiral spring wound around a shaft and mounted on the lintel beam or the wall portion above the gate opening, and connected with the actual gate.
- Another known sectional gate makes use of a more intelligent mounting system, whereby one component to be mounted on another component is provided of one or more hooks from which the curved or widened free end can cooperate with a hole in the second component.
- a problem though introduced by such mounting system comprising hook, consists of the fact that more space is required than the volume of both components.
- the hook should be brought through the hole and afterwards, the second component comprising the hook, or the first component comprising the hole, requires a secondary displacement as for example a downward movement.
- the required extra space is often critical as for example in the case of the spring system is to be mounted with such a hook mounting system.
- the available height between the top of the gate opening and the ceiling of a garage is often smaller than the required height for mounting such known spring system.
- US 5,964,268 discloses a sectional gate for closing at least partly a gate opening, said gate comprising :
- the vertical profile are provided with a bearing plate provided with a slot for receiving a cylindrical mounting portion of a gear housing, while the gear housing has two opposite flanges adapted for contacting two flange mounts of the bearing plate.
- Said bearing plate is attached to the profile by means of bolts.
- the spring system is quite heavy, especially in case of fire-resisting section gate.
- the place where the spring system has to be located is difficult of access, due to limited space and as the spring system has to be mounted well above the ground level. It is therefore quite difficult to move simultaneously several cylindrical mounting portion in the slots of the various bearing plate, such movement requiring simultaneous identical movement of the ends of the spring system. Any difference of movement between the ends of the spring system will not permit a correct attachment or any attachment of the ends of the spring system.
- this step is even rendered more complicated as it is necessary to ensure that simultaneously the various housings are correctly moved so that opposite flanges are directed so as to be able to move between the flange mounts of the bearing plate.
- the placement of the spring system is quite difficult.
- the placement of the spring system is even rendered more complicated, as in case the distance between the vertical profile is not correct, it is necessary to remove the possibly already attached end of the spring system and to lay back the spring system on the ground before adapting the position of the vertical profile. This is quite time consuming.
- the sectional gate of the invention has for aim to facilitate the placement of the spring system, which can possibly be operated by one single workman.
- a single workman can attach a first end portion of the spring system on a first mounting plate. After said attachment, the workman can pivot the spring system so as to place the second end portion at the place where it needs to be attached. The workman can thus easily attach said second end portion of the spring system, without any problem.
- substantially horizontal unidirectional click systems are used so as to further facilitate the mounting of the spring system.
- the invention relates to a sectional gate for closing at least partly a gate opening, said gate comprising :
- the weight to be lifted by the work man is reduced by a factor of about 2, while enabling an easy and quick attachment.
- the first connecting system while being connected to the first mounting plate supporting the first end portion of the spring system is adapted for enabling a pivotment of the elongated member of the spring system with respect to a substantially horizontal axis, when the second end portion of the elongated member of the spring system is not supported by said second mounting plate, while the second connecting system while being connected to the second mounting plate supporting the second end portion of the spring system is adapted for enabling a pivotment of the elongated member of the spring system with respect to a substantially horizontal axis, when the first end portion of the elongated member of the spring system is not supported by said first mounting plate.
- the workman can select the end portion of the spring system to be firstly be attached.
- At least the first connecting system is a horizontally unidirectional click system, said system being adapted for a unidirectional click in a direction perpendicular to the elongated axis of the spring system, said direction defining the substantially horizontal axis for the pivotment of the first connecting system while being connected to the first mounting plate supporting the first end portion of the spring system, when the second end portion of the elongated member of the spring system is not supported by said second mounting plate.
- Such an embodiment enables a very easy attachment of the first end portion of the spring system. There will thereafter be no problem for the workman to lift the second end portion of the spring system for pivoting it towards its substantially horizontal position for enabling the attachment thereof to the second mounting plate.
- Said second end portion can be attached to the second mounting plate by various connecting systems suitable for preventing a downwards pivotment of the second end.
- Such connecting systems are for example connecting systems using one or more hooks, connecting systems using one or more pins adapted to extend in hole(s) at least of the mounting plate for preventing a downwards pivotement, bolt(s), movable plates, profile, U-profile or corner plate(s) (for example movable towards a position acting as a support for the second end portion), one or more click system and combinations thereof.
- the first connecting system is a horizontally unidirectional click system, said system being adapted for a unidirectional click in a direction perpendicular to the elongated axis of the spring system, said direction defining the substantially horizontal axis for the pivotment of the first connecting system while being connected to the first mounting plate supporting the first end portion of the spring system, when the second end portion of the elongated member of the spring system is not supported by said second mounting plate, and in that the second connecting system is a horizontally unidirectional click system, said system being adapted for a unidirectional click in a direction perpendicular to the elongated axis of the spring system, said direction defining the substantially horizontal axis for the pivotment of the second connecting system while being connected to the second mounting plate supporting the second end portion of the spring system, when the first end portion of the elongated member of the spring system is not supported by said first mounting plate.

- the roller means 3A that are provided at the top of the upper panel 2A are guided by a separate mainly horizontal guide rail 9 which is slightly bent downwards near the gate opening.
- the sectional gate 1 further comprises a spring system 10 comprising for example two spiral springs 11 wound around a tubular shaft 12 (the axis of which defines the elongated axis of the spring system 10), each with one end connected to the shaft 12 and with the other end connected to a fixed bearing plate 13 supporting each an end portion of the shaft 12.
- a spring system 10 comprising for example two spiral springs 11 wound around a tubular shaft 12 (the axis of which defines the elongated axis of the spring system 10), each with one end connected to the shaft 12 and with the other end connected to a fixed bearing plate 13 supporting each an end portion of the shaft 12.
- an electric motor 14 is provided, in this case fixed to the ceiling of a garage and provided of a chain 15 connected to the upper panel 2A of the sectional gate 1.
- Figure 6 shows more in detail how the bearing plate 13 is provided of a hole 16 through which a free end of the shaft 12 is brought.
- the bearing plate 13 is connected to a mounting plate 17 by means of a horizontal unidirectional click-system.
- the mounting plate 17 is fixed by means of bolts 18 to the wall portion aside and above the gate opening.
- the portion of the shaft 12 extending through the opening 16 in the bearing plate 13 is provided with a reel 19 whereon a cable 20 is wound which is connected with the lower panel 2B of the sectional gate 1.
- the mounting plate 17 is interconnected with a vertical generally L-shaped profile 21 whereon the U-shaped profile of the vertical guide rail 6 is mounted. According to the invention, the interconnection is realised with a vertical unidirectional click-system.
- the mounting plate 17 can be further fixed by means of bolts 18 to the wall portion aside and above the gate opening. Said further fixing is easy as it is no more necessary to sustain the spring system 10.
- Figure 6 represents the downwardly oriented portion 22 of the second horizontal guide rail 9 near the gate opening, which is mounted on the generally L-shaped profile 21 by means of a unidirectional click-system.
- Figures 6 illustrates that the mounting plate 17 is generally L-shaped and comprises a first substantially vertical flank 23 (perpendicular to the mounting direction Z of the bolts 18, when bolts are required), and a second substantially vertical flank 24 which is substantially perpendicular to the first vertical flank 23 (and parallel to said direction Z of the bolts 18 when used).
- the first vertical flank 23 is provided of four holes 25 for possible bolts 18, two ribs 26 for fortifying the flank 23, and a protruding end portion 27 with U-shaped cross-section wherein two holes 28 are provided.
- first flank 23 is provided of a downwardly oriented projection 29 (vertical projection).
- the second flank 24 stretches out to well below the first flank 23, and is provided of a downward oriented hook 30, two protruding points 31, a hole 32 and an elastic lip 33.
- the bearing plate 13 mounted on the mounting plate 17 is composed of a plate portion 34 wherein the hole 16 is provided with an end portion 35 which form and shape are such that it can co-operate with the protruding end portion 27 of the mounting plate 17.
- the end portion 35 is provided with one single protrusion 36 adapted to co-operate with the hole 28 provided in the protruding end portion 27 of the mounting plate 17.
- the spring system 10 When the protrusion 36 of the end portion of the bearing plate 13 (bearing a first end portion of the spring system 10) is pressed into the hole 28 of the protruding end portion 27 of the mounting plate 17, while the protrusion of the other bearing plate (bearing the second end portion of the spring system) is not engaged in the hole 28 of the other mounting plate, the spring system 10 is able to pivot around the horizontal axis H1 which is the axis of the protrusion 36.
- the protrusion 36 connected to the bearing plate 13 is built up as a mainly conical portion 37 widening from its free end 38 up to its transition into a cylindrical portion 39 with a slightly smaller diameter as compared to the biggest diameter of the conical portion 37, which cylindrical portion 39 stretches out to a shoulder 40.
- a groove 41 is provided in the conical portion 37 and the cylindrical portion 39 that reaches up to the shoulder 40 and that provides the protrusion 36 of two flexibly movable legs.
- the cylindrical portion 39 of the protrusion 36 facilitates the pivotment of the spring system with respect to the horizontal axis of said cylindrical portion 39.
- the free end of the first flank 42 is folded such that an end portion 44 is parallely oriented to the second flank 43.
- the end portion 44 is near its upper free end 45 provided of a cut 46, and an upper portion 47 of this folded end portion 44 is further folded so that it is positioned parallel to the first flank 42 and forming a narrow space 48 in between. Said narrow space 48 acts as guiding means.
- the second flank 43 is provided of two square holes 49 and a round hole 50, which holes are positioned with respect to the upper portion 47 such that they can co-operate with the two protruding points 31 on the mounting plate 17, when the downwardly oriented projection 29 of the mounting plate 17 is slit in the narrow space 48.
- flanks 42 and 43 of the generally L-shaped profile 21 are further provided of a groove 51.
- the mounting plates 17 at both sides of the gate opening are mounted on the generally L-shaped profiles 21, more in particular by sliding the downwardly oriented projection 29 of the mounting plate 17 in the narrow space 48.
- the elastic lip 33 in the meantime co-operates with the free border of the generally L-shaped profile 21.
- the bearing plate 13 is assembled with the shaft 12 of the spring system 10.
- the spring system 10 is provided at least at one of its end portion, preferably at its two end portions 10A,10B with a removable protruding part 100 (see figure 7 ). Said protruding parts make extension of the shaft 12, whereby enabling to place easily the spring system 10 on the guide rails 9.
- the spring system 10 is thus supported by said guide rails 9 in the neighbourhood of the mounting plates 17. A single workman can then easily lift an end portion 10A of the spring system so that the protrusion 36 of the bearing plate 13 of said end portion is in front of the hole 28 of the mounting plate 17 (see figure 4 ).
- the spring system 10 pivotes (movement R1) around the axis H1 of the protrusion 36 connecting the first end portion 10A to the first mounting plate 17 (see figure 11 ) Thereafter, a horizontal movement of the protrusion 36 of the bearing plate 13 of the second end portion 10B is sufficient for engaging said protrusion into the hole 28 of the second mounting plate 17.
- the second end portion 10B of the spring system is then supported by the mounting plate 17. (see figures 12 to 14 )
- the protruding parts 100 (forming extension of the shaft 12) can be removed.
- the mounting plate 17 is advantageously provided with a spring wire 104 having substantially a U shape.
- the protrusion 36 has then advantageously a circular groove extending between the cylindrical part 39 and the frustoconical end 37, said groove being adapted to receive portions of the spring wire.
- the pivotment of the spring system 10 is quite limited, for example a few degrees, for example less than 10 degrees.
- the spring system is not first lifted for being supported by the guide rails 9.
- the shaft 12 is advantageously not provided with a protruding part.
- the workman clips the protrusion 36 of a first bearing plate of the first end portion of the spring system 10 on the first mounting plate 17, For said clipping the second end portion of the spring system contacts the ground, whereby less effort is required from the workman for achieving a correct position of the bearing plate with respect to the mounting plate intended to support the first end portion of the spring system.
- the workman has to lift the second end portion of the spring system.
- Such a lift movement is facilitated as the first end portion is already supported. Said movement generates a pivotment of the spring system 10.
- the distance between the bearing plates 13 of the spring system will be adjusted before attaching a first bearing plate on a first mounting plate for supporting the first end portion of the spring system, and thus before the pivotment step of the spring system.
- the distance between the bearing plates will thus be adapted in function of the distance between the mounting plates prior to the attachment of a first bearing plate on a first mounting plate.
- the spring system can possibly be mounted away from the opening to be closed.
- the sectional gate is advantageously provided with a supporting profile 110 away form the opening to be closed, said profile 110 acting advantageously as support for a portion or an end of the guide rails 7 and 9.
- the workman attaches two mounting plates 17, by means of screws or bolts, but advantageously at least by a clocking system.
- bolts 101 are engaged in holes 102,103 of the bearing plates and the mounting plates, holes which are located the one in front to another when the spring system is in horizontal position, ( figure 22 ).
- the protrusions / click systems 36 of the end portion 35 of the bearing plate are adapted to be clicked in the hole 28 of the end portion of the mounting plate 17, by a uni horizontal pushing movement.
- This unidirectional mounting is extremely easy and makes sure that the bearing plate 13 is firmly mounted on the mounting plate 17. Furthermore, such a connection can be undone by applying an external force, more in particular by squeezing a conical portion 37 and pulling back the spring system.
- the mounting of a sectional gate 1 according to the invention can be continued by applying the guide rails 5, the electric motor 14, eventually provided of one or more similar unidirectional click-systems in order to make it possible for one person to mount such a sectional gate 1 according to the invention.
- the panels 2 are mounted by bringing the roller means 4 in the guide rails 5 and by connecting these panels 2 mutually by means of the articulating means 3.
- the upper roller means 3A of the upper panel 2A are guided in the separate mainly horizontal guide rail 9 which is provided near the gate opening of the downwardly oriented portion 22.
- the chain 15 is connected to the upper panel 2A and the cable 20 from the reel 19 is connected to the lower panel 2B.
- some alternative unidirectional click-systems are represented which in each case comprises at least a protrusion 52 provided on a first component 53 and holding means 54 for holding said protrusion 52 provided on a second component 55.

Description
- The present invention concerns a sectional gate, in particular a gate comprising an articulated wall intended to extend substantially in vertical plane when said wall is in closed position.
- The panels of such sectional gate are mutually connected by means of articulating means which are also provided with roller means, which are meant to be guided by guide rails from a first position corresponding to the closed position of the sectional gate, to a second position corresponding to the open position of the sectional gate.
- The opening and closing of the gate is usually facilitated by an electric motor and/or a spring system. The spring system usually comprises a spiral spring wound around a shaft and mounted on the lintel beam or the wall portion above the gate opening, and connected with the actual gate.
- A problem that is known from such sectional gates is that the components of such gates are in general rather heavy and therefore, these gates are difficult to assemble and not suitable to be mounted by only one person.
- In the case of a fire-resisting section gate, the panel, the guiding means, the spring system, and the electric motor become heavier.
- It is known that, when bolts are used for mounting a sectional gate, at least two workmen, if not three, are required, one or two sustaining the pieces brought together while another screws the bolts in their fixed position. The placement of the spring system is time consuming.
- Another known sectional gate makes use of a more intelligent mounting system, whereby one component to be mounted on another component is provided of one or more hooks from which the curved or widened free end can cooperate with a hole in the second component.
- A problem though introduced by such mounting system comprising hook, consists of the fact that more space is required than the volume of both components.
- Indeed, the hook should be brought through the hole and afterwards, the second component comprising the hook, or the first component comprising the hole, requires a secondary displacement as for example a downward movement.
- It is clear that also sidewise secondary displacements require extra space.
- Another problem is that the spring system requires to be correctly maintained and displaced in horizontal direction, movement which is not easy even when made by two workmen.
- The required extra space is often critical as for example in the case of the spring system is to be mounted with such a hook mounting system.
- Indeed, the available height between the top of the gate opening and the ceiling of a garage is often smaller than the required height for mounting such known spring system.
- The same occurs when an electric motor is to be mounted to the ceiling.
-
US 5,964,268 discloses a sectional gate for closing at least partly a gate opening, said gate comprising : - an articulated wall comprising panels coupled together, whereby the gate extends in its closed position between a bottom edge of a bottom panel and an upper edge of an upper panel ;
- at least two guide rails adapted for guiding the movement of the panels between a closed position in which they are adapted for closing at least substantially an opening and an open position and an open position in which panels are not closing said opening ;
- at least one spring system with at least one flexible members attached to a panel, preferably to a bottom panel, said spring system being adapted for facilitating panels to move along the guide rails at least for the opening of the sectional gate, said spring system comprising an elongated member intended to extend substantially above the gate opening,
- at least two vertical profiles for supporting the spring system,
- at least two distinct connecting systems adapted for attaching the elongated member of the spring system to the vertical profiles so as to extend above the gate opening, whereby at least one of said connecting systems comprises a unidirectional click system,
- In the embodiment of
US 5,964,268 , the vertical profile are provided with a bearing plate provided with a slot for receiving a cylindrical mounting portion of a gear housing, while the gear housing has two opposite flanges adapted for contacting two flange mounts of the bearing plate. Said bearing plate is attached to the profile by means of bolts. - A major problem, when mounting such sectional gate, especially of the type disclosed in
US 5,964,268 , is that it is rather difficult to place safely, correctly and without risk of damages of pieces of the sectional gate or parts thereof, especially when mounting the spring system. - Indeed, the spring system is quite heavy, especially in case of fire-resisting section gate. Moreover, the place where the spring system has to be located is difficult of access, due to limited space and as the spring system has to be mounted well above the ground level. It is therefore quite difficult to move simultaneously several cylindrical mounting portion in the slots of the various bearing plate, such movement requiring simultaneous identical movement of the ends of the spring system. Any difference of movement between the ends of the spring system will not permit a correct attachment or any attachment of the ends of the spring system.
- Moreover, this step is even rendered more complicated as it is necessary to ensure that simultaneously the various housings are correctly moved so that opposite flanges are directed so as to be able to move between the flange mounts of the bearing plate. Even with two workmen, the placement of the spring system is quite difficult. The placement of the spring system is even rendered more complicated, as in case the distance between the vertical profile is not correct, it is necessary to remove the possibly already attached end of the spring system and to lay back the spring system on the ground before adapting the position of the vertical profile. This is quite time consuming.
- The sectional gate of the invention has for aim to facilitate the placement of the spring system, which can possibly be operated by one single workman. Indeed, in the sectional gate of the invention, a single workman can attach a first end portion of the spring system on a first mounting plate. After said attachment, the workman can pivot the spring system so as to place the second end portion at the place where it needs to be attached. The workman can thus easily attach said second end portion of the spring system, without any problem.
Advantageously, substantially horizontal unidirectional click systems are used so as to further facilitate the mounting of the spring system. - Furthermore, in advantageous embodiment, by using simple tool, it is also possible for a single workman to remove very easily the spring system, so as to replace it by a new one, or so as to repair it on the ground and to reclick it in place after repair or maintenance work.
- The invention relates to a sectional gate for closing at least partly a gate opening, said gate comprising :
- an articulated wall comprising panels coupled together, whereby the gate extends in its closed position between a bottom edge of a bottom panel and an upper panel;
- at least one substantially vertical profile ;
- at least two guide rails adapted for guiding the movement of the panels between a closed position in which they are adapted for closing at least substantially an opening and an open position and an open position in which panels are not closing said opening;
- possibly means adapted for driving the movement of panels at least between their closed position and their open position ;
- at least one spring system with at least one flexible members attached to a panel, preferably to a bottom panel, said spring system being adapted for facilitating panels to move along the guide rails at least for opening partly the sectional gate, said spring system comprising an elongated member intended to extend at a level substantially above the gate opening, said elongated member having an elongated axis,

Such an embodiment enables a very easy attachment of the first end portion of the spring system. There will thereafter be no problem for the workman to lift the second end portion of the spring system for pivoting it towards its substantially horizontal position for enabling the attachment thereof to the second mounting plate. Said second end portion can be attached to the second mounting plate by various connecting systems suitable for preventing a downwards pivotment of the second end. Such connecting systems are for example connecting systems using one or more hooks, connecting systems using one or more pins adapted to extend in hole(s) at least of the mounting plate for preventing a downwards pivotement, bolt(s), movable plates, profile, U-profile or corner plate(s) (for example movable towards a position acting as a support for the second end portion), one or more click system and combinations thereof.

Figures 1 and2 shows asectional gate 1 composed ofpanels 2 which are mutually connected forming an articulated wall by means of articulatingmeans 3 provided of roller means 4. - These roller means 4 can co-operate with
guide rails 5 at both sides of the gate opening, mainly composed of U-shaped profiles, from which infigure 2 only one side is represented. - Both
guide rails 5 are more in particular composed of avertical guide rail 6 and ahorizontal guide rail 7 which are interconnected by means of acurved portion 8. Saidvertical guide rail 6 is attached to a L-shapedvertical profile 21. - In order to guarantee that the upper panel 2A is positioned in line with the
other panels 2 when thesectional gate 1 is closed, the roller means 3A that are provided at the top of the upper panel 2A are guided by a separate mainlyhorizontal guide rail 9 which is slightly bent downwards near the gate opening. - The
sectional gate 1 further comprises aspring system 10 comprising for example two spiral springs 11 wound around a tubular shaft 12 (the axis of which defines the elongated axis of the spring system 10), each with one end connected to theshaft 12 and with the other end connected to a fixedbearing plate 13 supporting each an end portion of theshaft 12. - At a distance from the gate opening, an
electric motor 14 is provided, in this case fixed to the ceiling of a garage and provided of achain 15 connected to the upper panel 2A of thesectional gate 1. -
Figure 6 shows more in detail how the bearingplate 13 is provided of ahole 16 through which a free end of theshaft 12 is brought. - The bearing
plate 13 is connected to a mountingplate 17 by means of a horizontal unidirectional click-system. - The mounting
plate 17 is fixed by means ofbolts 18 to the wall portion aside and above the gate opening. - The portion of the
shaft 12 extending through theopening 16 in the bearingplate 13 is provided with areel 19 whereon a cable 20 is wound which is connected with the lower panel 2B of thesectional gate 1. - The mounting
plate 17 is interconnected with a vertical generally L-shapedprofile 21 whereon the U-shaped profile of thevertical guide rail 6 is mounted. According to the invention, the interconnection is realised with a vertical unidirectional click-system. - After said clicking, the mounting
plate 17 can be further fixed by means ofbolts 18 to the wall portion aside and above the gate opening. Said further fixing is easy as it is no more necessary to sustain thespring system 10. -
Figure 6 represents the downwardly orientedportion 22 of the secondhorizontal guide rail 9 near the gate opening, which is mounted on the generally L-shapedprofile 21 by means of a unidirectional click-system. -
Figures 6 illustrates that the mountingplate 17 is generally L-shaped and comprises a first substantially vertical flank 23 (perpendicular to the mounting direction Z of thebolts 18, when bolts are required), and a second substantiallyvertical flank 24 which is substantially perpendicular to the first vertical flank 23 (and parallel to said direction Z of thebolts 18 when used). - The first
vertical flank 23 is provided of fourholes 25 forpossible bolts 18, tworibs 26 for fortifying theflank 23, and aprotruding end portion 27 with U-shaped cross-section wherein twoholes 28 are provided. - Further, the
first flank 23 is provided of a downwardly oriented projection 29 (vertical projection). - The
second flank 24 stretches out to well below thefirst flank 23, and is provided of a downward orientedhook 30, two protrudingpoints 31, ahole 32 and anelastic lip 33. - The bearing
plate 13 mounted on the mountingplate 17 is composed of aplate portion 34 wherein thehole 16 is provided with anend portion 35 which form and shape are such that it can co-operate with theprotruding end portion 27 of the mountingplate 17. - The
end portion 35 is provided with onesingle protrusion 36 adapted to co-operate with thehole 28 provided in theprotruding end portion 27 of the mountingplate 17. - When the
protrusion 36 of the end portion of the bearing plate 13 (bearing a first end portion of the spring system 10) is pressed into thehole 28 of theprotruding end portion 27 of the mountingplate 17, while the protrusion of the other bearing plate (bearing the second end portion of the spring system) is not engaged in thehole 28 of the other mounting plate, thespring system 10 is able to pivot around the horizontal axis H1 which is the axis of theprotrusion 36. - In
figure 23 , theprotrusion 36 and the co-operation with itsrespective hole 28 is more in detail represented. - In this embodiment, the
protrusion 36 connected to the bearingplate 13 is built up as a mainlyconical portion 37 widening from itsfree end 38 up to its transition into acylindrical portion 39 with a slightly smaller diameter as compared to the biggest diameter of theconical portion 37, whichcylindrical portion 39 stretches out to a shoulder 40. In theconical portion 37 and the cylindrical portion 39 agroove 41 is provided that reaches up to the shoulder 40 and that provides theprotrusion 36 of two flexibly movable legs.
Thecylindrical portion 39 of theprotrusion 36 facilitates the pivotment of the spring system with respect to the horizontal axis of saidcylindrical portion 39. - The generally L-shaped
profile 21, represented in detail infigures 6A and6B , whereon the mountingplate 17 is to be mounted, is provided of afirst flank 42 and a perpendicularsecond flank 43. - The free end of the
first flank 42 is folded such that anend portion 44 is parallely oriented to thesecond flank 43. - The
end portion 44 is near its upperfree end 45 provided of acut 46, and anupper portion 47 of this foldedend portion 44 is further folded so that it is positioned parallel to thefirst flank 42 and forming anarrow space 48 in between. Saidnarrow space 48 acts as guiding means. - The
second flank 43 is provided of twosquare holes 49 and around hole 50, which holes are positioned with respect to theupper portion 47 such that they can co-operate with the twoprotruding points 31 on the mountingplate 17, when the downwardly orientedprojection 29 of the mountingplate 17 is slit in thenarrow space 48. - Both flanks 42 and 43 of the generally L-shaped
profile 21 are further provided of agroove 51. - The mounting of such
sectional gate 1 as described above is easy and as follows. - One could start by mounting, for example screwing, the L-shaped
profiles 21 to the reveals or the side walls, where the screws can be brought through thegrooves 51. - The mounting
plates 17 at both sides of the gate opening are mounted on the generally L-shapedprofiles 21, more in particular by sliding the downwardly orientedprojection 29 of the mountingplate 17 in thenarrow space 48. - At the same time, the two
protruding points 31 on the mountingplate 17 are moved towards the twosquare holes 49 and coincide therewith when thehook 30 comes in contact with the generally L-shapedprofile 21. - The
elastic lip 33 in the meantime co-operates with the free border of the generally L-shapedprofile 21. - According to an embodiment, the bearing
plate 13 is assembled with theshaft 12 of thespring system 10. Thespring system 10 is provided at least at one of its end portion, preferably at its twoend portions figure 7 ). Said protruding parts make extension of theshaft 12, whereby enabling to place easily thespring system 10 on the guide rails 9. Thespring system 10 is thus supported by saidguide rails 9 in the neighbourhood of the mountingplates 17.
A single workman can then easily lift anend portion 10A of the spring system so that theprotrusion 36 of the bearingplate 13 of said end portion is in front of thehole 28 of the mounting plate 17 (seefigure 4 ). By a horizontal movement of the bearingplate 13 towards the mountingplate 17, theprotrusion 36 enters into thehole 28, so that thefirst end portion 10A of the spring system is supported by the mounting plate 17 (seefigures 8 and9 ) Such a movement is quite easy as the workman has only to lift half of the weight of the spring system, said workman having furthermore only to correctly place asingle protrusion 36 in front of ahole 28.
The workman has then to lift theother end portion 10B of thespring system 10, so that theprotrusion 36 of the bearingplate 13 bearing thesecond end portion 10B of the spring system extends in front of thehole 28 of the mountingplate 17. During said lift movement, thespring system 10 pivotes (movement R1) around the axis H1 of theprotrusion 36 connecting thefirst end portion 10A to the first mounting plate 17 (seefigure 11 ) Thereafter, a horizontal movement of theprotrusion 36 of the bearingplate 13 of thesecond end portion 10B is sufficient for engaging said protrusion into thehole 28 of the second mountingplate 17. Thesecond end portion 10B of the spring system is then supported by the mountingplate 17. (seefigures 12 to 14 ) - After the placement of the
spring system 10 so as to be supported by the two mountingplates 17, the protruding parts 100 (forming extension of the shaft 12) can be removed. - In order to better attach the bearing
plates 13 on the mountingplates 17, it is possible to usebolts 101 which are engaged in holes 102,103 of the bearing plates and the mounting plates, holes which are located the one in front to another when the spring system is in horizontal position. - In order to prevent the removal of the
protrusion 36 of a bearing plate during a rotation or pivotment of saidbearing plate 13 with respect to the mountingplate 17, the mountingplate 17 is advantageously provided with aspring wire 104 having substantially a U shape. Theprotrusion 36 has then advantageously a circular groove extending between thecylindrical part 39 and thefrustoconical end 37, said groove being adapted to receive portions of the spring wire. When pressing the protrusion into thehole 28, the legs of the U shapedspring 104 are moved away from each other. When the said legs of the U shaped spring are in front of the groove said legs spring into said groove and act as holding means for preventing any accidental removal of theprotrusion 36 out of thehole 28 during a pivotment of thespring system 10. - In this method, the pivotment of the
spring system 10 is quite limited, for example a few degrees, for example less than 10 degrees. - In another method, the spring system is not first lifted for being supported by the guide rails 9. In such a method, the
shaft 12 is advantageously not provided with a protruding part.
In said method, the workman clips theprotrusion 36 of a first bearing plate of the first end portion of thespring system 10 on the first mountingplate 17, For said clipping the second end portion of the spring system contacts the ground, whereby less effort is required from the workman for achieving a correct position of the bearing plate with respect to the mounting plate intended to support the first end portion of the spring system.
After said clipping, the workman has to lift the second end portion of the spring system. Such a lift movement is facilitated as the first end portion is already supported. Said movement generates a pivotment of thespring system 10. Such a pivotment ensures that the bearingplate 13 of the second end portion of the spring system will be correctly placed with respect to the mounting plate, when the spring system is horizontal. A simple horizontal movement of the bearing plate towards the mountingplate 17, will then be sufficient for clipping the bearing plate and the mountingplate 17 together (seefigures 10 to 12 ). - Advantageously the distance between the bearing
plates 13 of the spring system will be adjusted before attaching a first bearing plate on a first mounting plate for supporting the first end portion of the spring system, and thus before the pivotment step of the spring system. The distance between the bearing plates will thus be adapted in function of the distance between the mounting plates prior to the attachment of a first bearing plate on a first mounting plate. - The spring system can possibly be mounted away from the opening to be closed.
- In such a case, the sectional gate is advantageously provided with a supporting
profile 110 away form the opening to be closed, saidprofile 110 acting advantageously as support for a portion or an end of theguide rails - On said supporting profile, the workman attaches two mounting
plates 17, by means of screws or bolts, but advantageously at least by a clocking system. - Thereafter, the workman lift a first end portion of the
spring system 10, while the other end portion still contacts the grounds. The lifting operation is so facilitated, whereby the correct positioning of the bearingplate 13 of said first end portion with respect to the first mountingplate 17 is also facilitated, as said positioning no more require the lifting of the spring system, but only a horizontal movement of the bearing plate towards the mountingplate 17, (seefigures 15 to 17 ). - When said first bearing plate is attached to the first mounting plate, the
spring system 10 is pivoted around the axis H1 of theprotrusion 36 of the first bearing plate. The upwards movement of the second bearing plate and the second end portion of the spring system is thus facilitated (figures 18 and19 ). - As the distance between the bearing
plates 13 was adapted to the distance between the mountingplates 17 prior to the fixation of the first bearing plate on the first mounting plate, when theshaft 12 of thespring system 10 is horizontal, theprotrusion 36 of the second bearing plate will extend in front of thehole 28 of the mountingplate 17, whereby a simple horizontal movement will be sufficient for clicking said protrusion into saidhole 28, (figure 20 and21 ). - Thereafter, as for the other embodiment,
bolts 101 are engaged in holes 102,103 of the bearing plates and the mounting plates, holes which are located the one in front to another when the spring system is in horizontal position, (figure 22 ). - The protrusions /
click systems 36 of theend portion 35 of the bearing plate are adapted to be clicked in thehole 28 of the end portion of the mountingplate 17, by a uni horizontal pushing movement. - Thanks to the narrow
free end 38 of theconical portion 37 of theprotrusions 36, the movement of the protrusions towards theholes 28 is further guided. Said conical end portions act as directing means integrated in the unidirectional click-system, whereby the relative positioning of the bearingplates 13 with respect to the mountingplates 17 is facilitated during said horizontal pushing (seefigure 23 ). - Further pushing causes an elastic deformation of the
conical portion 37, i.e. the legs created by thegroove 41 forming the locking means are pushed together. - The dimensions of the
protrusions 36 and the choice of the elastic material make it possible that such elastic deformation is reversed when the end position is reached. - Indeed, when the
conical portion 37 is completely brought through anopening 28, thecylindrical portion 39 having a smaller diameter than thehole 28 and the biggest diameter of the conical portion being bigger than the diameter of thehole 28, the legs of theprotrusion 36 are moved in their original position. - This unidirectional mounting is extremely easy and makes sure that the bearing
plate 13 is firmly mounted on the mountingplate 17. Furthermore, such a connection can be undone by applying an external force, more in particular by squeezing aconical portion 37 and pulling back the spring system. - After mounting the
spring system 10, the mounting of asectional gate 1 according to the invention can be continued by applying theguide rails 5, theelectric motor 14, eventually provided of one or more similar unidirectional click-systems in order to make it possible for one person to mount such asectional gate 1 according to the invention. - Further, the
panels 2 are mounted by bringing the roller means 4 in theguide rails 5 and by connecting thesepanels 2 mutually by means of the articulatingmeans 3. - The upper roller means 3A of the upper panel 2A are guided in the separate mainly
horizontal guide rail 9 which is provided near the gate opening of the downwardly orientedportion 22. - The
chain 15 is connected to the upper panel 2A and the cable 20 from thereel 19 is connected to the lower panel 2B. - It is clear that the unidirectional click-system can be realised in different manners.
- In
figures 24 to 27 , some alternative unidirectional click-systems are represented which in each case comprises at least aprotrusion 52 provided on afirst component 53 and holding means 54 for holding saidprotrusion 52 provided on asecond component 55. According to the invention, theprotrusion 52 or the holding means 54 comprise elastic locking means 56 that can be displaced into an open position by bringing theprotrusion 52 in the holding means 54 and that is elastically repositioned into a closed position when bothcomponents - In
figure 24 , the unidirectional click-system is provided of agroove 57 and of a conicalfree extremity 58. In this case, the holding means 54 comprise ahole 59 in thesecond component 55 and also the above mentioned elastic locking means 56, which in this case comprise two opposing springs 60, each acting on a ball 61 captured in ahousing 62. - The balls 61 are moved aside into an open position of the holding means 54, more in particular when the conical
free extremity 58 is pushed in thehole 59. When thegroove 57 coincides with the balls 61, the balls 61 move back to a closed position of the holding means 54 and as a consequence, theprotrusion 52 is captured and held by the holding means 54. A strong pulling force or a force pulling back the springs 60 may suffice to pull loose thefirst component 53 from thesecond component 55. -
Figure 25 represents a similar unidirectional click-system which therein differs from the preceding click-system that the balls 61 are substituted bychamfered block elements 63. - As opposed to the helical springs 60 of the preceding click-systems, the click-systems as represented in
figures 26 and 27 are provided of holding means 54 made as one elasticallydeformable element 64. - It is clear that such a
protrusion 52 can be provided of two ormore grooves 57, so that the components can be mounted according to at least two preferred mutual positions by simply pushing the components further in the mounting direction until the desired position is reached. - In
figure 28 such an alternative connection for the bearingplate 13 on the mountingplate 17 provided of two preferred mutual positions is represented. The connection is realised by sliding the surfaces of two components on top of each other. Further pushing the two components in that mounting direction will bring them in the second desired position. Such a clicking system can be used for attaching the second end portion of the spring system after having attached the first end portion by a connecting system enabling a rotation or pivotement of the spring system around a horizontal axis perpendicular to the axis of the spring system. - In this case and also in the unidirectional click-systems, as represented in the
figures 29 to 31 , it is theprotrusion 52 that is provided of the above mentioned elastic locking means 56. - Also in this case, it is clear that more than one preferred final mutual position can be obtained, for example by providing two recesses in line on the bearing plate for holding the movable protrusion.
- In case, the bearing
plate 13 is provided with twoprotrusions 36, the mounting plate has then to be provided with an opening for a first protrusion and a second opening adapted for enabling a movement of the other protrusion in and along the opening in case of a pivotment of the bearing plate. Possibly the two openings have to be shaped so as to permit such a pivotment. - It is clear from the discussed variants that a lot of variants for the unidirectional click-systems can be identified.
- It should also be clear that a lot of components of the
sectional gate 1, although all are not represented in the drawings, can be mounted by means of a unidirectional click-system. Indeed, it is clear that for example also the cone which is usually mounted on the bearingplate 13, more in particular on the opposite side from thereel 19, can be mounted thereon by means of a unidirectional click-system, for example existing of protrusions comprising sideways movable flanks which can elastically be moved in the body of the protrusion. - We also mention for reasons of completeness that a connection of components by means of a unidirectional click-system can be meant for facilitating the mounting, and that, after the mounting of two components by means of such a click-system, the components are often further connected by means of for example bolts.
- It is clear that a
sectional gate 1 with vertical panels can also be provided of such unidirectional click-systems, and that the advantages of the unidirectional click-system are even of more importance for the heavier components of fire resistantsectional gates 1. - Of course, the unidirectional click-system can also be applied to roller shutters for the same of similar reasons.
- The present invention is by no means limited to the embodiments given as examples and can be realised according to different variants while still remaining within the scope of the invention, as defined by the claims.
