Definitions

  • the present disclosure generally relates to fire doors and, in particular, to: a retaining device for use in retaining an infill panel in a fire door; and a method of installing an infill panel in a fire door using said retaining device.
  • Fire-rated doors are doors constructed of materials that work together to slow or stop the spread of flames, smoke and, in certain applications, radiant and conductive heat transfer. Common materials utilised in fire-rated door construction include wood, steel, fiberglass, fire-rated glass, and combinations of these materials.
  • Fire-rated door assemblies are given a fire rating determined through standardised tests. Typically, fire-rated doors are subjected to a fire endurance test to determine their fire rating. This test is used to measure how long the door remains intact without failure under application of extreme heat, i.e., the fire resistance of the door.
  • each door leaf of a fire door comprises a frame and at least one infill panel retained within the frame. The quicker an infill panel breaks or fails to perform its function during a fire, the lower the fire resistance and thereby fire rating of the fire door.
  • One potential way in which a door leaf may fail during a fire is if an infill panel of the door leaf falls out of the frame of the door leaf: the fallen infill panel is no longer able to perform its function of preventing the spread of fire through the door leaf. Therefore, it would be advantageous to provide a fire door assembly wherein the infill panel or infill panels are retained more securely within each door leaf.
  • One way of improving the retention of an infill panel within a door leaf is attaching the infill panel to the frame of the door leaf using a retaining device.
  • a portion of the retaining device is generally bent against the infill panel, to thereby grip the infill panel, using a glazing tool.
  • the glazing tool tends to slip (e.g. away from the infill panel) while being used to apply a force to bend the retaining device.
  • the infill panel is therefore not gripped as tightly by the retaining device and is more prone to failure (i.e., falling out of the frame) during a fire.
  • the second issue is that the installation of the infill panel is more challenging and/or slower because the person installing the retaining device needs to be careful to avoid the glazing tool slipping.
  • the person installing the retaining device needs to reapply a force to bend the retaining device, further increasing the time and physical exertion required to complete installation and wearing out the person installing the retaining device more quickly.
  • An additional downside to slipping of the glazing tool is that the desired angle of bend cannot be achieved easily, safely, and without risk of infill panel damage.
  • document DE 10 2019 133 839 A1 discloses a fire door with a retaining device comprising two legs that are bent upwardly against the infill panel.
  • document DE 10 2005 057 389 B3 discloses a fire door with a retaining device made of two parts.
  • the present disclosure solves these problems by providing an improved retaining device, which can be positioned inside existing fire doors and facilitates easier and more consistent infill panel installation.

  • An angle of bend of 90° achieves the greatest contact area between the at least one leg 40A, 40B and the second side 230 of the infill panel 140. In other words, this desired angle allows the infill panel 140 to be held most securely within the frame, thereby reducing the likelihood of the infill panel 140 falling out of the frame, in particular in the event of a fire either side of the door.
  • the retaining device 1 of the present disclosure achieves, on average, an angle of bend of the at least one leg of between 85-90°.
  • a retaining device not comprising a protrusion 60 but otherwise identical to the retaining device 1 of the present disclosure achieves, on average, an angle of bend of the at least one leg of between 70-90°. Accordingly, the protrusion 60 helps to achieve a more consistent angle of bend.
  • the protrusion 60 also facilitates installation of the infill panel 140.
  • the protrusion 60 may increase the speed of installation of the infill panel 140 in the frame by up to 65 % when compared to installing an infill panel using a retaining device not comprising the protrusion 60 but otherwise identical.
  • the protrusion 60 acts as both a support and point of rotation for a glazing tool 190 when bending the at least one leg 40A, 40B.
  • the protrusion 60 also acts to indicate the location where the glazing tool 190 must be inserted in the retaining device 1, i.e., between the protrusion 60 and the side wall 510.
  • the protrusion 60 may add to the strength of the retaining device 1 by acting as a stiffening rib.
  • the present disclosure further provides a method of installing an infill panel 140 in a frame of a door leaf 100 of a fire door using at least one retaining device 1000 of the present disclosure.
  • the method of installing an infill panel 140 in a frame of a door leaf 100 of a fire door using at least one retaining device 1000 comprises attaching the first base 20 of the retaining device 1000 to the first frame member 120 and the second base 50 of the retaining device 1000 to the second frame member 130.
  • the additional piece 220 is attached to the second base 50.
  • the infill panel 140 is then placed in between the first frame member 120 and the second frame member 130.
  • a glazing tool 190 such as the glazing tool 190 of the present disclosure
  • the forward edge of a glazing tool 190 is placed in the corner joining the sidewall 510 of the middle portion 30 to the second base 50 of the retaining device 1000.
  • the at least one leg 40A, 40B is then bent by pivoting the glazing tool 190, while using the additional piece 220 as support, until the at least one leg 40A, 40B is pressed against the infill panel 140.
  • a glazing bead 110 is then attached to the second frame member 130.
  • the additional piece 220 is attached to the second base 50 at the same time as the second base 50 is attached to the second frame member 130.
  • the glazing tool 190 when the forward edge of a glazing tool 190 is placed in the corner joining the sidewall 510 to the second base 50, the glazing tool 190 is located between the second base 50 and the at least one leg 40A, 40B. As the glazing tool 190 is pivoted in the in direction of the infill panel 140, the glazing tool 190 contacts the at least one leg 40A, 40B. The force exerted on the at least one leg 40A, 40B by the glazing tool 190 cause the at least one leg 40A, 40B to bend in a direction towards the infill panel 140.
  • a front edge 700 of the additional piece 220 acts to prevent the glazing tool 190 from slipping backwards in a direction away from the sidewall 510 when being pivoted to bend the at least one leg 40A, 40B. Reducing slippage of the glazing tool 190 allows the desired angle of bend of the at least one leg 40A, 40B to be achieved more consistently, while also reducing the physical effort exerted by the installer.
  • the desired angle of bend is 90°, wherein the angle of bend is measured between the second base 50 and the at least one leg 40A, 40B.
  • An angle of bend of 90° achieves the greatest contact area between the at least one leg 40A, 40B and the second side 230 of the infill panel 140.
  • this desired angle allows the infill panel 140 to be held most securely within the frame, thereby reducing the likelihood of the infill panel 140 falling out of the frame, in particular in the event of a fire either side of the door.
  • the retaining device 1000 of the present disclosure like the retaining device 1, achieves, on average, an angle of bend of the at least one leg of between 85-90°.
  • a retaining device not comprising an additional piece 220 but otherwise identical to the retaining device 1000 of the present disclosure achieves, on average, an angle of bend of the at least one leg of between 70-90°. Accordingly, the additional piece 220 helps to achieve a more consistent angle of bend, while also reducing the physical effort exerted by the installer.
  • the additional piece 220 also facilitates installation of the infill panel 140.
  • the additional piece 220 may increase the speed of installation of the infill panel 140 in the frame by up to 65 % when compared to installing an infill panel using a retaining device not comprising the additional piece 220 but otherwise identical.
  • the front edge 700 of the additional piece acts as both a support and point of rotation for a glazing tool 190 when bending the at least one leg 40A, 40B.
  • the front edge 700 also acts to indicate the location where the glazing tool 190 must be inserted in the retaining device 1000, i.e., between the front edge 700 and the side wall 510.
  • the glazing tool 190 of the present disclosure is advantageous when used in the methods as described herein.
  • the glazing tool 190 comprises a gripping portion 290 having a longitudinal axis parallel to a forward edge 300 of the wedged portion 270.
