Definitions

  • This invention relates to an assembly for sealing doors more particularly, but not exclusively to sealing refrigerated van doors.
  • a flexible seal of substantially 'U' shaped cross section is provided, the arms of the 'U' extend in a direction parallel to the plane of the door and co-operate with a door frame or pillar surrounding the door to be sealed.
  • the lengths of the arms are crucial because too short a length would not ensure a sufficient seal and too long a length would increase the resistance necessary to pull open the sealed door due to the tips of the arms becoming bent and catching the door frame or pillar.
  • Such seals are susceptible to wear and tear and therefore need replacing, this involves complete dismantling of the sealing arrangement. In addition to being unnecessarily expensive to replace it is also time consuming during which time the van is rendered inoperative and meanwhile losing I>business.
  • Hollow seals have previously been proposed having a circular cross-section but these have previously only been used as a compression seal and therefor extend in a direction transverse to the plane to the door.
  • the door 1 has parallel front and back panels 10 and 11 respectively.
  • the front panel 10 extends slightly beyond the back panel 11.
  • the sealing assembly is attached on each edge of the door between the front and back panels 10 and 11 and comprises a substantially rigid member 2 for attachment to the inside of the panels 10 and 11 in the region of the periphery thereof for closing the gap therebetween.
  • the rigid member 2 is preferably arranged to lie substantially flush with the periphery of the panels 10 and 11 and because the front panel 10 extends slightly beyond the back panel 11 the rigid member 2 tapers along a substantial length between one panel and the other.
  • the rigid member 2 has a recess 3 between the front and back panels for receiving a holder 4 which has a C-shaped cross section and may have serrated sides for additional grip with the recess 3 when the rigid member 2 is moulded around the holder 4.
  • a first sealing member 5 made from suitably flexible material such as P.V.C. capable of being compressed and advantageously capable of withstanding temperatures in the region of -40°c without degradation of its properties and having retaining means 14 extending from the base thereof for being removably located in said holder.
  • the sealing member 5 protrudes outwardly from the holder 4 in a direction parallel to the plane of the door and in use communicates in a compressed condition with a door frame or pillar 9 surrounding the door 1. Between the frame 9 and the door 1 there is provided a gap no less than the height of the seal when fully compressed so as to enable the seal to be inserted.
  • FIG. 1 One type of door frame to be sealed with the door including a sealing assembly as described above is shown in Figure 1 in which the door frame 9 may be provided with a tapping plate 13 preferably welded on the inside of the outer wall of the door frame similarly a tapping plate 13 may be provided on the inside of the front panel 10 of the door 1, for providing means to hinge the door 1 on either side of the frame 9.
  • the door frame 9 may be surrounded by a shield 12 as shown in Figures 1 and 2 but advantageously the part of the door frame 9 which co-operates with the seal 5 when in use should be heat insulative.
  • the shield 12 may be isolated from the intei-ioroof the container by providing a suitable heat break with which the sealing member 5 co-operates when the door is in position in the door frame 9 as shown in Figure 2.
  • shield 12 and the plate or wall 7 may be made of the same material and may be of one material moulded or bent around the heat break 6.
  • FIG. 3 Another variation of the door frame construction is shown in Figure 3 in which the door frame 9 has an edge which is of registering shape to the edge of the door 1 i.e. the door frame has a first portion extending substantially at right angles from the outer wall 12 for co-operation with the sealing member 8 and an angled portion which is arranged to be parallel to the tapered portion of the door when the door is in its closed position. This arrangement again caused compression and shearing forces to be exerted on the sealing member 5.
  • Figure 4 shows a preferred form of the sealing member 5 suitable for use in the above mentioned sealing assembly.
  • the sealing member has a pear shaped cross section and retaining means extending from the narrow part of the sealing member capable of being removably located in the holder 4.
  • the "pear" part of the upper part of the sealing member 5 projects from the holder and by virtue of its material and wall thickness is capable of being compressed by say 1/7th of its original height and when in a compressed condition is capable of shearing for providing a "rolling action".
  • the air trapped inside the upper part of the seal provides an insulator between the air on either side of the seals and in addition to the air trapped between the secondary seal and the part of the door frame 9 opposite the secondary seal which acts as an insulator between the atmosphere and the air between the secondary seal member and the first sealing member provides a substantially airtight, thermotight seal.
  • the sealing member 5 is longitudinal and the retaining means 14 preferably 'T' shaped whereby the bar of the T can be slid along the holder 4 on each side of the door 1. At the corners of the door 1 the sealing member 5 on one side is bonded with the sealing member 5 on the adjacent side to form a mitre edge.
