Definitions

  • the present invention relates to an actuation device for moving a slidable closing element between a closed position and an open position, the slidable closing element being a sliding window, a sliding door or the like, the actuation device including a slidable carrier member for engaging the slidable closing element, the slidable carrier member being biased for sliding movement by means of a spring element, and the movement of the slidable carrier member being damped by means of a piston assembly arranged displaceably in a cylinder between a first end of the cylinder and a second end of the cylinder in such a way that a difference in gas pressure may be created between a first side of the piston assembly and a second side of the piston assembly.
  • EP 0 589 822 B1 discloses an opening device for a sliding window or door.
  • the opening device includes a slider arranged slidably along the inside of a guide rail having a rectangular cross-section.
  • the slider is provided with two so-called constant force springs having free ends fixed to a first end of the guide rail, thereby urging the slider in the direction of said first end of the guide rail.
  • the slider is provided with a drive member extending out through a longitudinally extending slot provided in a wall of the guide rail so that the drive member may engage an edge of the window or door to be opened.
  • the opening device furthermore includes a dampening cylinder arranged at an end of the guide rail.
  • a piston arranged in the dampening cylinder is connected to the slider by means of a piston rod in order to dampen the movement of the slider.
  • a shorter device may be required.
  • US 4,004,372 discloses a coil spring type closer for sliding doors which is adapted to cushion and retard the final stages of the closing movement of the door by means of a dampening cylinder arranged on a door frame.
  • this closing arrangement is only able to dampen the final stages of the closing movement which may be insufficient in the case of large doors or windows or in the case of a number of successively arranged slidable elements adapted to be opened or closed sequentially by means of the device.
  • the device requires an installation length that is substantially longer than the stroke of sliding element to be opened or closed.
  • the object of the present invention is to provide an actuation device of the above-mentioned type that is more compact.
  • the spring element is arranged to extend inside the cylinder between the first or second end of the cylinder and the piston assembly, a first guide roller is arranged at the first end of the cylinder and a second guide roller is arranged at the second end of the cylinder, a first wire section extends inside the cylinder from the piston assembly, around the first guide roller, outside the cylinder to the slidable carrier member, and a second wire section extends outside the cylinder from the slidable carrier member, around the second guide roller, and inside the cylinder to the piston assembly, so that the slidable carrier member is displaceable together with the piston assembly.
  • the combined effect of arranging the spring element to extend inside the cylinder and arranging wire sections guided around guide rollers for displacing the slidable carrier member together with the piston assembly may provide an actuation device that is much more compact than known devices.
  • the spring element is adapted to bias the piston assembly towards a position at the second end of the cylinder
  • the first end of the cylinder is provided with a first end plug
  • the first end plug has a hole through which the first wire section extends
  • the difference between the outer diameter of the first wire section and the diameter of the hole is small enough in order to create a pressure reduction inside the cylinder between the first end plug and the piston assembly when the piston assembly travels in the direction against the second end of the cylinder.
  • the piston assembly or the first end plug is provided with a check valve allowing air to flow through the check valve out from the space in the cylinder between the first end plug and the piston assembly when the piston assembly travels in the direction against the first end of the cylinder, but preventing air from flowing through the check valve into the space in the cylinder between the first end plug and the piston assembly when the piston assembly travels in the direction against the second end of the cylinder.
  • the dampening effect may be obtained as the biased spring element is released to displace the slidable closing element in the direction against the second end of the cylinder, but the dampening effect may be avoided when the slidable closing element is returned in the direction against the first end of the cylinder. It may therefore be easier to return the slidable closing element, which may for instance be done manually.
  • the spring element is formed by one or more so-called constant force springs
  • each constant force spring includes a strip coiled on a drum, and the strip exerts an at least substantially constant restraining force to resist uncoiling.
  • the necessary force may be adapted to individual requirements by including a suitable number of constant force springs.
  • the drum is mounted on the piston assembly and the strip has a free end fixed to the cylinder at its second end.
  • the rolled-out part of the strip will not translate in relation to the cylinder as the piston assembly is displaced, and thereby sliding resistance and resulting wear may be prevented. Possible wear of the inside of the cylinder wall could result in that the piston assembly would not seal properly against the cylinder wall.
  • the piston assembly includes a first piston part connected to a second piston part by means of two spaced apart plates, the drum of the one or more so-called constant force springs is fixed between the two spaced apart plates, and at least the first piston part includes a cylindrical section sealed against the cylinder.
  • the first and second piston parts may thereby be spaced apart and therefore provide good guidance of the entire piston assembly in the cylinder so that it may be avoided that forces resulting from the constant force spring or springs may skew the piston assembly in the cylinder.
  • the second piston part is adapted to be guided along the inside of the cylinder and includes a recess, said recess being so formed and so arranged that the rolled-out part of the strips of the so-called constant force springs may extend through the recess when the piston assembly is displaced in the cylinder.
  • the strips may extend through a recess in the second piston part that does not necessarily need to be sealed but may be guided in order to steer the piston assembly in the cylinder. Thereby, a sealing mechanism between the strips and the piston assembly may be avoided.
  • the recess of the second piston part is formed in the periphery of the second piston part.
  • an even more compact actuation device may be provided, as the diameter of the cylinder may be so small that the rolled-up strips on their drums may just fit inside the cylinder.
  • friction between the strips and the second piston part may be minimized, as practically only an inner side of the innermost strip in the cylinder may slide against the recess of the second piston part; the outer side of the strips may at least substantially not translate in relation to the inside of the cylinder and therefore not contribute with any friction.
  • a first end plug has a recess in which the first guide roller is arranged partly extending from the recess
  • a second end plug has a recess in which the second guide roller is arranged partly extending from the recess.
  • each one of the first end plug and the second end plug is adjustably connected to a respective mounting bracket for the device, so that the first and second end plugs are rotatably adjustable in relation to the mounting bracket about a central axis of the cylinder.
  • the exact position of the part of the first and second wire sections extending outside the cylinder may be adapted to the desired position of the slidable carrier member according to tolerances and according to possible different configurations of a slidable closing element to be actuated.
  • the slidable carrier member is arranged to travel at least substantially in parallel with the travel direction of the piston assembly.
  • the axis of the cylinder of the actuation device may be arranged at least substantially in parallel with a slidable closing element to be actuated, and the slidable carrier member may easily be directly mounted on said slidable closing element.
  • the first or the second wire section is attached to the slidable carrier member via a tension spring. Thereby, it may be ensured that the first and second wire sections are maintained suitably tensioned.
  • the first or the second wire section is attached to the slidable carrier member by means of an adjustment mechanism allowing adjustment of the tension of the wire section, for instance by rotation of a screw.
  • the first and second wire sections may be manually tensioned upon installation of the actuation device or subsequently in the case that the wire sections should become too loose during operation.
  • the present invention further relates to a balcony closing arrangement including a number of successively arranged slidable window elements adapted to close a balcony and an actuation device as described above arranged to move the slidable window elements to open position upon actuation, wherein the slidable carrier member is adapted to engage a first slidable window element, wherein a second and possibly further slidable window elements each are provided with a protrusion for engagement with a neighbouring slidable window element, so that when the first slidable window element is moved from a first end of the balcony closing arrangement in an opening direction, the second and possibly further slidable window elements may subsequently be moved in the opening direction one after each other so that, finally, all slidable window elements will be positioned substantially behind each other at a second end of the balcony closing arrangement, and wherein the first slidable window element is provided with a coupling part adapted to engage an automatic release mechanism arranged at the first end of the balcony closing arrangement so that activation of the automatic release mechanism may
  • Fig. 1 shows a balcony closing arrangement 1 including four successively arranged slidable window elements 2A, 2B, 2C, 2D adapted to close a balcony in the position shown in Figs. 1 and 3 .
  • a first slidable window element 2A which in the closed position is positioned at a first end 6 of the balcony closing arrangement, at the right side in the figure, is automatically displaceable in the left direction by means of an actuation device 3 according to the present invention arranged along an upper edge of the balcony closing arrangement 1 or is manually displaceable by means of a handle 4.
  • the second, third and fourth slidable window elements 2B, 2C, 2D are each provided with a protrusion 5 for engagement with a left edge of a neighbouring slidable window element 2A, 2B, 2C, respectively, so that when the first slidable window element 2A is moved from the first end 6 of the balcony closing arrangement 1 in an opening direction, the second, third and fourth slidable window elements 2B, 2C, 2D may subsequently be moved in the opening direction one after each other so that, finally, all slidable window elements 2A, 2B, 2C, 2D are positioned substantially behind each other at a second end 7 of the balcony closing arrangement 1, as shown in Fig. 2 .
  • the protrusions 5 may furthermore be used as a handle for manually returning the second, third and fourth slidable window elements 2B, 2C, 2D to the initial position shown in Figs. 1 and 3 or for manually opening one of these elements by displacement in the left or right direction from the closed position show in
  • Figs. 1 and 3 upon displacement of the first slidable window element 2A, the other slidable window elements 2B, 2C, 2D may be in any possible position to which they have been previously moved manually. Regardless of the initial position of each of the other slidable window elements 2B, 2C, 2D, the position of the elements after automatic opening by the actuation device 3 will be as illustrated in Fig. 2 , whereby all slidable window elements 2A, 2B, 2C, 2D are positioned substantially behind each other at a second end 7 of the balcony closing arrangement 1.
  • each of the slidable window elements 2A, 2B, 2C, 2D is slidable in a separate corresponding track 8A, 8B, 8C, 8D in an upper horizontal balcony profile 9, as illustrated in Fig. 9 .
  • the lower edge of each of the slidable window elements 2A, 2B, 2C, 2D is slidably mounted on a lower horizontal profile 10 in a well-known manner by means of not shown rollers.
  • panel type filling elements 13 are arranged, further separated by an intermediate vertical profile 14.
  • filling elements may be arranged in any suitable way or they may be unnecessary, depending on the balcony to be covered.
  • the actuation device 3 is adapted to constantly bias the first slidable window element 2A in the opening direction, that is to the left in Fig. 1 , when the first slidable window element 2A is positioned at the first end 6 of the balcony closing arrangement, as discussed in further detail below. Therefore, the first slidable window element 2A is provided with a coupling part 15 adapted to engage an automatic release mechanism 16 arranged at the first end 6 of the balcony closing arrangement on a vertical profile 17 so that activation of the automatic release mechanism 16 may release the coupling part 15, whereupon the actuation device 3 may move the slidable window elements from the first to the second end of the balcony closing arrangement.
  • the automatic release mechanism 16 has the form of an electromagnetic coil adapted to attract an anchor plate 19 of the coupling part 15. Thereby, the opening of the balcony closing arrangement may be initiated electrically, for instance by means of a fire alarm, smoke detector or the like.
  • the automatic release mechanism 16 and the coupling part 15 may have any other suitable configuration depending on requirements.
  • the coupling part 15 is further provided with a roller 20 adapted to roll on an edge of the upper horizontal balcony profile 9; thereby it may be ensured that the first slidable window element 2A does not skew when it is pulled manually by the handle 4 or by the actuation device 3.
  • the roller 20 is mounted in a recess of a bracket 21 that is mounted to the first slidable window element 2A by means of screws 22; however, the roller 20 may also be mounted on the first slidable window element 2A by means of an element separate from the coupling part 15 in any suitable way.
  • the actuation device 3 is shown in cross-section in Figs. 5 and 6 , seen sideways and from the top, respectively.
  • the actuation device 3 is adapted for moving a slidable closing element between a closed position and an open position.
  • the slidable closing element may be a sliding window, a sliding door or the like.
  • it is illustrated how the actuation device 3 may be employed for the automatic opening of a balcony closing arrangement 1 including a number of successively arranged slidable window elements 2A, 2B, 2C, 2D as described above.
  • the actuation device 3 includes a slidable carrier member 23 for engaging the slidable closing element which in the embodiments illustrated has the form of the first slidable window element 2A of the balcony closing arrangement 1.
  • the slidable carrier member 23 is biased for sliding movement by means of a spring element 24, and the movement of the slidable carrier member 23 is damped by means of a piston assembly 25 arranged displaceably in a cylinder 26 between a first end 27 of the cylinder and a second end 28 of the cylinder in such a way that a difference in gas pressure may be created between a first side 29 of the piston assembly and a second side 30 of the piston assembly.
  • the spring element 24 is formed by one or more so-called constant force springs 35A, 35B and is arranged to extend inside the cylinder 26 between the second end 28 of the cylinder 26 and the piston assembly 25.

  • a compression spring could also be arranged to extend inside the cylinder 26 between the second end 28 of the cylinder 26 and the piston assembly 25 in the case that the actuation device 3 should be adapted to bias the first slidable window element 2A in the closing direction instead of in the opening direction or in the case that the actuation device 3 should be arranged with the first and second ends 27, 28 of the cylinder reversed in relation to the embodiment described with relation to the figures.
