Definitions

  • the present invention relates to a sectional door, suitable for installation in garage doors, industrial warehouses or docking bays, amongst others.
  • the sectional door described herein includes a coupling mechanism which allows said door to be completely or partially lowered, wherein when it is partially lowered, a lower section of the door is grounded on the floor whereas an upper section of the door is in a raised position, leaving an opening between said sections of the door for ventilation, safety and/or illumination reasons.
  • sectional doors are widespread in industrial warehouses, docking or loading bay areas and garage openings of private households, amongst other similar locations. Furthermore, there are have been certain improvements of sectional doors which allow independent sections of the door, basically an upper section and a lower section (each section comprising one or more panels), to be moved independently from one another, usually when the door has already been grounded and disconnecting the upper section from the lower section, raising it to a preferred position. This improves lighting, temperature and air circulation inside the property where it is installed, whilst still providing certain safety measures as the lower section is still grounded in a closed position.
  • patent EP 1825093 B1 discloses a vertically movable door, made up of an upper and a lower section, which is movable between an open and a closed position. When the door is in a closed position, the lower section can be released from the upper section by means of a disconnectable joint, enabling the upper section to be lifted whilst leaving the lower section in a barrier position, providing an opening between the upper and lower sections of the door.
  • the different disconnectable joints described herein are either manually operated or use an electromechanical actuator.
  • Patent US 7726378 B1 discloses a similar door configuration, wherein upper door panels of the door may be partially raised with regards to lower panels of the door, when said lower panels of the door are resting on the ground, leaving a space between the upper and lower panels.
  • The includes split hinges arranged on both the left and right-hand door edge as well as a central location of the door, so that said split hinges may connect or disconnect adjacent panels of the door, through the use of quick-release pins.
  • US patent application 2016/265582 A1 discloses an automatic or manually operated sectional door hinge system which enables a sectional door to change between a single door section rollable as a single unit, to a separated configuration having a plurality of rollable door sections.
  • the sectional door has an upper section which may be moved to an elevated or raised position independently from a lower door section adjacent to the ground.
  • the invention disclosed herein aims to improve existing coupling mechanisms used in sectional doors, by using a mechanical solution which doesn't require the use of either a person to manually operate a component of said mechanism or the use of electronic or electromechanical control systems, in order to couple or uncouple the upper and lower sections of a door.
  • the present invention discloses a sectional door which can be used for industrial applications (warehouse doors, cargo or loading bay areas, etc.) as well as household applications (garage doors of private households) which is capable of being completely opened, completely closed or partially opened.
  • These sectional doors are made up of:
  • said one or more panels that make up each section of the door are joined or fastened together in an articulated configuration in order to allow both sections of the door to be guided adequately along different possible frame designs.
  • the present invention differs from other similar doors in that the one or more coupling units it has installed on the door make use of a coupling mechanism which is purely mechanical, and doesn't require the use of additional electronic control systems or manual labour in order to couple or uncouple the upper section of the door from the lower section of the door.
  • the first housing is attached to an inner side of the upper section of the door adjacent to the lower end thereof
  • the second housing is attached to an inner side of the lower section of the door adjacent to the upper end thereof.

If it is symmetrical, the clamping connector comprises two cylindrical rods, opposite one another, arranged inside respective symmetrical guiding grooves, whereas if it is asymmetrical, then the clamping connector would suffice with one cylindrical rod arranged inside a respective guiding groove.
  • the number of coupling units used and their positioning on either section of the door changes according to a width of the door onto which they are installed, as well as a weight they must be capable of withstanding, in order to operate in optimum working conditions. For example, if the width of the door is equal to or lower than 4600mm the number of coupling units used in comparison to doors with a width larger than 4600mm, is smaller, wherein each coupling unit can include one or more coupling mechanisms each.
  • the elongated appendix further comprises a latch movable between an active position and a passive position.

  • the second housing 6 is also partially inserted in the lower cavity 50b of the first housing 5.
  • the actuator 4 proceeds to raise the upper section 2a of the door 2 up to a prearranged position (see Fig. 4 ), such as completely or partially raised, whilst the lower section 2b of the door 2 remains grounded.
  • the width of the adjustable opening 9a of the clamping connector 9 is at least as wide as that of the base portion 8a, it can be removed easily as both the thickened end portion 8c and the intermediate portion 8b of the elongated appendix 8 are both narrower than its base portion 8a, and the retaining devices 10 are also at a sufficient distance when in their final standby positions 13 in order to avoid collisions with the elongated appendix 8 whilst the upper section 2a of the door 2 is being raised.

  • transversal wall 6b of the second housing 6 is attached or fixed to an upper end of the lower section 2b of the door 2.
  • the coupling mechanism 7 is primarily made up of a clamping connector 9, arranged inside cavity 50 of the first housing 5, fixed to its wall 5b, and an elongated appendix 8 arranged inside cavity 60 of the second housing 6, also fixed to its wall 6b.
  • the elongated appendix 8 is asymmetrical having a wall or side which is substantially flat whilst the other wall or side varies in width throughout its extension.
  • FIGs. 1a to 1d The explanation used in FIGs. 1a to 1d is also valid for FIGs. 2a to 2d , with the only difference that the elongated appendix 8 is asymmetrical, as stated previously, and therefore it only uses one of its two retaining devices 10 in its respective groove 100 to block the different positions of the coupling mechanism 7, using the remaining retaining device 10' and groove 100' as a guiding element, granting the coupling mechanism 7 more stability.
  • the clamping connector 9 has two retaining devices 10, 10', preferably cylindrical rods, located inside respective guiding grooves 100, 100', one of the retaining devices 10' is only used as guiding element as it has a groove 100' which only allows the cylindrical rod to move longitudinally against the flat side of the elongated appendix 8.
  • the remaining retaining device 10 has a guiding groove 100 which allows it to transition from an initial standby position 11 to a final standby position 13, when the elongated appendix 8 is inserted or removed from inside the clamping connector 9, in a similar fashion as described previously in FIGs. 1a to 1d .
  • the final standby position 13 is at a different height with reference to that of the initial standby position 11.
  • FIG. 3a illustrates a sectional door 2, according to the present invention, in a specific position in which the upper section 2a of the door 2 has been uncoupled and elevated from the lower section 2b of the door 2 which is grounded.
  • This is possible through the use of one or more coupling units 7, installed in the door 2 and which are currently in an uncoupled configuration so that the upper section 2a of the door 2 can be uncoupled and elevated independently from the lower section 2b of the door 2, which remains grounded acting as a barrier.
  • This allows the inside of a building, where the door 2 has been installed, to be ventilated adequately as well as improving lighting of the areas near the door 2, whilst simultaneously using the lower section 2b of the door as a safety measure.
  • An actuator or motor (not shown in this figure) is connected to the upper section 2a of the door 2. It should be noted that even though no figure illustrates it, both sections 2a, 2b of the door 2 can also be moved as a single unit when the coupling unit 3 is in a coupling configuration.
  • FIG. 3a also shows the first housing 5 and the second housing 6 attached, respectively, to a lower end of the upper section 2a of the door 2 and to an upper end of the lower section 2b of the door, which together form the coupling unit 3.
  • FIG. 3a also shows:
  • the second brake device 15 is shown in great detail in FIGs. 4a to 4c , wherein its main components are: a mounting or support plate 151 which is fastened or attached to a panel of the upper section 2a of the door 2, in a position adjacent to the guiding rail or track of the frame 1, so that a first guiding wheel 153a, fastened to said mounting or support plate 151, can be positioned in said guiding rail or track of the frame 1.
  • the first guiding wheel 153a is designed to include a recess or cavity into which a transmission cable (not shown) is arranged, with one of its distal ends fastened to a hook 157 of the second brake device 15 and the remaining distal end connected to an actuator or motor of the sectional door 2.
  • a main plate 156 is fastened to the support plate 151 through the use of a first cylindrical dowel pin 152a, which defines a rotation axis or pivoting point for the main plate 156 to shift position with regards to the support plate 151.
  • the main plate 156 has a clamping device 155 fastened to it through the use of a second cylindrical dowel pin 152b which allows said clamping device 155 to vary its position between an active and a passive arrangement, wherein the hook 157 is fastened to a lower portion of the clamping device 155.
  • a distal end of the second cylindrical dowel pin 152b has a second guiding wheel 153b which is positioned or inserted inside the guiding track or rail of frame 1 of the door 2.
  • the second brake device 15 includes an adjusting mechanism 154 made up of a bolt and a nut, whereby the position of the nut along the thread of the bolt defines an angle, a, between the main plate 156 and the mounting plate 151, rotating or pivoting around a rotation axis defined by the first cylindrical dowel pin 152a, as seen in FIG. 4c .
  • This is necessary due to a gradual increase in an inclination of the frame 1 for these types of doors, from the ground upwards, and therefore the adjusting mechanism 154 allows a user to regulate a distance between the second brake device 15 and the guiding rail of frame 1, so that the second guiding wheel 153b is in an optimum position.
  • the clamping device 155 shifts from a passive arrangement, as seen in these figures, to an active arrangement upon failure of the transmission cable connected to the actuator of door 2, whereupon the clamping device 155 automatically rotates around an axis of rotation defined by the second cylindrical dowel pin 152b, as a result of a slackening of the transmission cable fastened to the hook 157, resulting in the clamping device 155 exerting a force or pressure against frame 1, which stops the upper section 2a of the door 2 from falling.
  • FIGs. 5a and 5b shows two positions of a safety device 16 installed on either side of the coupling unit 3, adjacent to the guiding rails or tracks of frame 1.
  • This safety device 16 is necessary mainly for two reasons:
  • the safety device 16 (see Figs. 5a and 5b ) is made up of a static protruding element 161, facing downwards, mechanically fastened to the upper housing 5 of the coupling unit 3, and a mobile protruding element 163 fastened to the lower housing 6 of the coupling unit 3.
  • the mobile protruding element 163 has a cable connecting it to a far end of a piston 164, said piston being mounted on a support 167 comprising to parallel walls with orifices through which the piston 164 is guided.
  • the piston 164 has a coaxial spring 165 mounted on a shaft and set between both walls of the support 167.
  • the mobile protruding element 163 has a transmission cable 166 connected to a first brake device 14, using a guiding wheel 168, arranged on the lowermost panel or portion of the lower section 2b of the door 2, adjacent to the guiding rail of frame 1.
  • the first brake device 14 is used to stop the lower section of the door from falling or collapsing in the event of transmission cable 166 failing.
  • the static protruding element 161 has a wheel 162, or other equivalent rotating device, fastened to it, so that when it is lowered, the wheel 162 moves along a surface of mobile protruding element 163, and forcing it to move laterally (see arrow C of FIG. 5b ) , counteracting a force exerted by the spring 165, which also causes a head of the piston 164 (seen in FIG. 5b ) to exit the guiding rail of frame 1, as well as changing the configuration of the first break device 14 to a passive or inactive arrangement, thus allowing the lower section 2b of the door 2 to be raised, together with the upper section 2a of the door 2, as a single unit.
  • the safety device 16 operates synergistically with the coupling mechanism 7 included in the coupling unit 3, which allows both sections 2a, 2b of the door 2 to be either coupled or uncoupled.
  • FIG. 5a it can be observed that a portion of the piston 164, specifically the head of the piston 164, is located inside the guiding rail or track of frame 1 of the door 2, so that the lower section 2b is kept in a fixed position. Furthermore, even though it isn't seen in these figures, when the upper section 2a of the door 2 is uncoupled from the lower section 2b, the first brake device 14 is in an active position, meaning that its clamp or retention element is exerting a force against frame 1, even when in a grounded position.
  • the elongated appendix 8 further comprises a latch 8d which can be moved parallel and adjacent to the intermediate portion 8b, said latch 8d having a thickness equal or bigger than the thickness difference between the intermediate portion 8b and the thickened end portion 8c of the elongated appendix 8.
  • the door includes one first housing 5 and one second housing 6 on each lateral side of the door 2 adjacent to the frame 1, each first housing 5 containing two clamping connectors 9 and each second housing containing two elongated appendix 8.
  • the second housing further comprises a manual actuator which is connected to the latches 8d of both elongated appendix 8 to produce its movement to the active position manually.
  • the movement of the latches 8d is also cinematically connected to a Bowden cable or a tensioned cable 70 which transmits the movement of the latches 8d housed in the second housing 6 of one side of the door 2 to the latches 8d contained in the second housing 6 placed on the opposed lateral side of the door 2, producing the simultaneous movement of all the latches 8d of the door 2 to produce the simultaneously releasing of the lower portion 2b.
  • This solution also permits the used to indistinctly activate the manual actuator integrated in any of the second housings 6 integrated in the door 2.
  • the coordination between the latches 8d is achieved through a first wheel integrated on each second housing 6 and cinematically connected to the latches 8d integrated in said second housing 6 to produce the rotation of said wheel in coordination with the movement of the latches 8d from the passive position to the active position or vice-versa.
  • the first wheels of both second housings 6 are connected to each other through a Bowden cable or a tensioned cable 70 which transmits the rotational movement of one first wheel to the other first wheel, mirroring the latch 8d movement from one second housing 6 to the latches 8d of the other second housing 6.
  • the elongated appendix 8 is movable in a vertical direction between a hanging position shown in Fig. 7c in which the lower portion 2b is hanging from the upper portion 2a through the elongated appendix 8, and an unhanging position in which the lower portion 2b is not hanging from the upper portion 2a.
  • This movement of the elongated appendix 8 is also in coordination with the first braking device 14 through a Bowden cable or a tensioned cable 71, to activate the braking of the first braking device 14 when the elongated appendix 8 are in the unhanging position, and to release the braking of the first braking device 14 when the elongated appendix 8 are in the hanging position.
  • said coordination is produced through a second wheel integrated on each second housing 6 and cinematically connected to the elongated appendix 8 integrated on said second housing 6 to produce the rotation of said second wheel in coordination with the movement of the elongated appendix 8 from the hanging position to the unhanging position or vice-versa.
  • the Bowden cable or tensioned cable 71 is connected to the periphery of said second wheel and to the first braking device 14, producing a coordination between said two connected elements, determining the activation or deactivation of the first braking device depending on the position of the elongated appendix 8.
