  • the docking assembly 800 can snap into place when inserted a sufficient distance into the docking aperture 340a.
  • the docking assembly 800 can include a tubular body 830 having legs 836, a cup 810 having a cup aperture 812, and a docking base 860 having a base aperture 862.
  • the docking assembly 800 has a plenum end 833 and a cage end 831.
  • the cup 810, the tubular body 830, the docking base 860, and the spring 890 are arranged coaxially.
  • the cup 810 is supported on the tubular body 830 and is slidably engaged with the tubular body 830.
  • the spring 890 surrounds the tubular body 830.
  • the docking base 860 is slidably engaged with the tubular body 830 proximate the plenum end 833.
  • the tubular body 830 has apertures 870, a body channel 834, and a retaining mechanism as further described below.
  • Tubular body 830 can also have a circular cross-section with an outer diameter smaller than the inside diameter of the cup 810.
  • the tubular body 830 is aligned coaxially with the cup 810 and the docking base 860.
  • the tubular body 830 includes a plurality of apertures
  • the apertures 870 are sized, shaped and arranged to be in fluid connection with the apertures 340a in the plenum 310 to provide controlled airflow to the cage.
  • the body channel 834 of the tubular body 830 extends through the length of the tubular body 830.
  • the body channel 834 can be aligned with the cup aperture 812.
  • the outwardly extending flange 832 is disposed on the perimeter of the tubular body 830 proximate the cage end 831.
  • the tubular body 830 also includes a retaining mechanism for connecting the docking assembly 800 to an aperture 340a in the plenum 310 and retaining the docking assembly 800 in position.
  • the tubular body includes a plurality of deflectable extended legs 836 extending toward the plenum end 833. Legs 836 are constructed and arranged to be inserted into the docking aperture 340a of the plenum 310.
  • the extended legs 836 are flexible and are displaceable inward into the body channel 834 and are normally disposed outward away from the body channel 834. Accordingly, as the legs 836 are inserted into the docking aperture 340a, the legs 836 are displaced (bent) by pressure toward each other. The portions of the legs 836 that have been inserted through the docking aperture 340a will then return to the normal non-deflected position and away from each other to secure the body to the plenum.
  • each leg 836 can include a foot 838 extending outward, away from the axis of the tubular body 830. Therefore, the cross-section of the leg 836 can be greater proximate the foot 838.
  • the foot 838 can include an angled insertion surface 838a and an abutment surface 838b.
  • the plenum wall 310a defining the docking aperture 340a contacts the angled insertion surface 838a of the foot 838.
  • the legs 836 are displaced inward until the feet 836 can be inserted through the docking aperture 340a. Once inserted, the legs 836 return to their position, more preferably, until the outer wall of the leg 836 contacts the portion of the plenum wall 31 Oa that defines the docking aperture 340a.
  • the tubular body 830 can further include a stopping element for preventing the displacement of the docking base 860 beyond a certain distance from the foot 838 when the tubular body 830 is engaged with the docking base 860.
  • the stopping element can include a stopping surface 840 extending outward from the outer wall of the tubular body 830 proximate the legs 836.
  • the tubular body 830 has a wider portion 842 and a narrower portion 844 wherein the legs 836 are within the narrower portion 844.
  • the stopping surface 840 can be provided where the wider portion 842 and the narrower portion 844 meet.
  • the diameter of the wider portion 842 is greater than the inner diameter of the base aperture 862 of the docking base 860, thus preventing the displacement of the docking base 860 past the stopping surface 840.
  • alternate stopping elements are contemplated.
  • the tubular body 830 can have a single diameter or a gradual change in diameter without a defined stopping surface, wherein the stopping element can include one or more bumps or other mechanism to prevent the docking base 860 from being displaced beyond a specified distance.
  • FIGS. 8-10 illustrate an embodiment of the cup 810, which can have a tubular shape having a cup aperture 812 for receiving the tubular body 830.
  • the cup 810 is supported on the tubular body 830 proximate the cage end 831 and is slideably displaceable along the axis of the tubular body 830.
  • the cup 810 also includes an inner lip 814 or other element/member extending inward into the cup aperture 812.
  • the inner lip 814 of the cup 810 contacts the outwardly extending flange 832 of the tubular body 830 (Fig. 11-12) to prevent the cup 810 from being displaced in direction H past the flange 832.
  • the cup 810 can also include an outer lip 816 extending radially outward from the cup aperture 812. Preferably, the outer lip 816 is located proximate the cage end 831.
  • the outer Hp 816 preferably contacts the wall of the cage. As the cage is pushed toward the plenum 310 in direction I, the wall of the cage can push the cup 810 via the outer lip 816 toward the plenum 310 in direction I against the biasing force of the spring 890, forcing the spring 890 to contact, and thus increasing the force exerted by the spring 890.
  • the docking base 860 includes a base aperture 862, a base abutment wall 864, and a base abutment surface 865.
  • the tubular body 830 may be at least partially placed through the base aperture 862 of the docking base 860 and be slideably engaged therewith.
  • the stopping surface 840 of the tubular body 830 prevents the docking base 860 from moving too far upwards toward the cage end 831 of the docking assembly 800.
  • a spring 890 is provided between the cup 810 and the docking base 860 to urge the cup 810 away from the docking base 860.
  • the spring 890 as shown in FIG. 4-5 is provided outside the tubular body 830, and more preferably surrounds the tubular body 830. Spring 890 contacts the base abutment wall 864 to apply a force, which urges the cup 830 away from the plenum wall and toward the cage.
  • the tubular body is inserted, at least partially, into the docking aperture 340a in the plenum wall 310a until a locking mechanism secures the tubular body 830 in place with respect to the plenum wall 310a.
  • the docking assembly 800 can preferably be mounted onto the plenum 310 by inserting the legs 836 in the direction I into the docking aperture 340a of the plenum 310.
  • the legs 836 can be displaced inward until the foot 838 clears the plenum wall 310a. Thereafter, the legs 836 can be displaced outward such that the foot 838 extends beyond the diameter of the docking aperture 340a and substantially prevents the legs 836 from being withdrawn in direction H.
  • the abutment surface 865 of the docking base 860 contacts the outside of the plenum wall 310a while the abutment surface 838b of the foot 838 of the tubular body 830 contacts the inner surface of the plenum wall 310a.
  • the base abutment wall 864 is wider than the docking aperture 340a, which facilitates sealing the docking aperture 340a to prevent leakage of air from between the docking assembly 800 and the vertical plenum 310.
  • the docking base 860 preferably prevents the tubular body 830 from being inserted too far into the docking aperture 340a.
  • the spring 890 simultaneously urges the docking base 860 toward the plenum wall 31 Oa until the base abutment surface 865 contacts the plenum wall 31 Oa.
  • no additional steps are necessary to secure the docking assembly 800 or to seal the connection between the docking assembly 800 and the plenum 310. Therefore, the installation of the docking assembly 800 onto the plenum 310 is relatively simple.

Abstract

La présente invention concerne un ensemble amarrage destiné à un système de cages et de casiers ventilés pouvant faciliter l’installation et réduire la fuite d’air. L’ensemble amarrage peut être raccordé à des collecteurs d’air du système de casiers et comprend une coupelle et un corps tubulaire comportant une base d’amarrage. Le corps tubulaire est construit et agencé pour être déplaçable en coulissant entre la coupelle et la base d’amarrage lorsque le corps tubulaire est aligné de façon coaxiale sur la coupelle et la base d’amarrage. Un ressort peut également être utilisé à l’extérieur et entourer le corps tubulaire. Le corps tubulaire comprend une pluralité de montants déplaçables. Les montants sont de préférence poussés vers l’extérieur en l’absence de pression et peuvent être déplacés vers l’intérieur, les uns vers les autres, pour s’insérer dans une ouverture d’amarrage d’un collecteur. Une fois insérés, les montants reviennent à leur position normale non déplacée, afin de fixer l’ensemble amarrage au collecteur.
