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 protrusion 52 or the holding means 54 comprise elastic locking means 56 that can be displaced into an open position by bringing the protrusion 52 in the holding means 54 and that is elastically repositioned into a closed position when both components 53 and 55 are in their final mounted position.
  • the unidirectional click-system is provided of a groove 57 and of a conical free extremity 58.
  • the holding means 54 comprise a hole 59 in the second 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 a housing 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 the hole 59.
  • the balls 61 move back to a closed position of the holding means 54 and as a consequence, the protrusion 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 the first component 53 from the second component 55.
  • Figure 25 represents a similar unidirectional click-system which therein differs from the preceding click-system that the balls 61 are substituted by chamfered block elements 63.
  • the click-systems as represented in figures 26 and 27 are provided of holding means 54 made as one elastically deformable element 64.
  • protrusion 52 can be provided of two or more 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.
  • connection for the bearing plate 13 on the mounting plate 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.
  • the bearing plate 13 is provided with two protrusions 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.
  • the two openings have to be shaped so as to permit such a pivotment.
  • sectional gate 1 can be mounted by means of a unidirectional click-system.
  • the cone which is usually mounted on the bearing plate 13, more in particular on the opposite side from the reel 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.
  • the unidirectional click-system can also be applied to roller shutters for the same of similar reasons.
