Description

LOCKING MECHANISM FOR AIR HANDLER (AHU) CABINET
Field of the Invention
This invention relates generally to an air handling unit having ducting which is made by a plurality of interconnected components or modules, and more specifically to a locking mechanism for connecting the modules.
Background of the Invention
Many air handling units found in the prior art are simply fabricated from sheet metal ducts that are brought together in the field to establish an enclosed flow path, through which air is conducted. The sheet metal walls of the ducts readily conduct heat and provide little in the way of a thermal barrier so that energy can flow into or out of the duct work. When the air handling unit is conducting conditioned air, this flow of energy into or out of the duct work can be costly and places an unwanted load on the air conditioning equipment.
In addition, when the air handling unit is installed in an unconditioned space and is carrying cooled air, the outer casing of the unit will "sweat". The moisture so developed will run off the unit onto the floor or equipment contained in the unconditioned space. This, in turn, will lead to a safety hazard for people working in the area and can cause damage to the equipment.
When conventional ducting of this type is installed and/or modified, the assembly or disassembly can be very costly. If this work is done improperly, it can lead to operational problems and warranty issues. This type of conventional ducting utilizes loose fasteners and/or the requirement for internal unit access. Typically the prior art ducting includes stand-off flanges which require separate hardware attachment. The numerous required pieces of hardware increase the probability for mistakes and errors in assembly and modifying ducting in the field, and has been a long standing problem in the field. Summary of the Invention
It is therefore an object of the present invention to provide a system for assembling and disassembling air ducts which overcomes the problems of the prior art described above. It is another object of the present invention to provide an improved ducting system for conducting air along a desired flow path.
It is a further object of the present invention to provide an improved locking mechanism for connecting modules which made up a duct carrying conditioned air.
It is another object of the present invention is to provide an improved locking mechanism for connecting components of a duct system which obviates the need for loose fasteners and associated hardware.
Yet another object of the present invention is to provide a simple external locking system for connecting components of a duct system for an air handling unit.
These and other objects of the present invention are accomplished by an air handling duct system for conducting air along an enclosed path of travel which utilizes a specially designed panel. The panel is used to form attachable sections and includes a rectangular frame made of a material having a high R value. The frame is closed by a top cover and a bottom cover so that a cavity is established within the panel. The cavity is filled with a curable material that sets inside the panel to bond the walls of the frame together and the covers to the frame.
The air handling duct system is made up of a plurality of rectangular sections or modules which are connected to each other by the locking mechanism of the present invention. The locking mechanism is in the form of mechanical latch which includes a male and a female retainer. The male and female retainers are installed separately into two adjoining (section) frame members. The latch is designed to be actuated from the outside of the frame with a common tool such as a hex wrench. The locking action joins the two sections together without the need for loose fasteners or the necessity for access to the inside of the unit. Brief Description of the Drawing
For a better understanding of these and other objects of the invention, reference will be made to the following detailed description of the invention which is to be read in association with the accompanying drawings, wherein: Fig. 1 is a perspective view showing a section of ductwork for conducting air along a desired flow path.
Fig. 2 is a partial perspective view of two modules illustrated in Fig. 1 positioned in interlocking engagement using the latch mechanism of the present invention. Fig. 3 is a view of the two modules of Fig. 2 in the open or unlocked position showing the relative position of the latch mechanism.
Fig. 4 is an enlarged sectional view of the latching mechanism taken along line 4-4 in Fig. 2.
Fig. 5 is an enlarged perspective view of two beam or rail sections of two adjacent modules aligned for locking engagement.
Fig. 6 is a perceptive view of Fig. 5 with a breakaway view of the rails in locking engagement.
Detailed Description of the Invention Referring to Fig. 1 of the drawings there is illustrated a portion of an air handling unit (AHU), generally referenced 10. The air handling unit is made up of a series of rectangular shaped modules each of which has its own superstructure made up of a pair of end frames 13 and 14 that are connected at the corners by horizontally disposed upper beams 15 and lower beams 16. Each end frame includes two opposed side rails 17 and 18 and an upper rail 20 and a lower rail 21. In assembly, the rails and the beams are retained slidably in corner pieces 23. The rails and the beams in assembly thus establish an open support structure or skeleton with the opening being closed by wall panels 12.
Each wall panel 12 is designed to be placed in the skeleton openings to close desired openings in the sections. Each panel is constructed to have an outer frame which defines an internal cavity 43. The panels are closed by a top cover and a bottom cover and the cavity is filled with a setable polyurethane foam 44 which when cured bond the panels together and forms a thermal barrier that impedes the flow of heat through the panel. Each panel is sized so that the panel frame can be slipped into an opening in one of the unit sections. A close sliding fit is provided between panel frame walls and the side rails and upper and lower beams that form the receiving opening. Seals are provided to prevent air from passing around the panels as well as through an addition thermal barrier between the inside of the unit and the surrounding ambient. When a panel has been locked into each of the openings, the designed air duct configuration such as that illustrated in FIG. 1 has been completed.
Fig. 2 illustrates a partial sectional view of two modular sections 30 and 40 joined together in locked engagement at their upper rails 32 and 42 to form adjacent sections in the air handling duct. In Fig. 3 the two modules are shown in the open or unlocked position with upper rail 32 containing one of a series of a locking mechanisms 50 used to lock the panels together as will be described in further detail below. The mechanism contains a male retainer which is designed to mate in locking engagement with open keyway 44 located in upper rail 42.
As shown in more detail in Figs. 4-6, the rails and beams are held in a closed or locked position by a series of locking or latching mechanisms. Each male retainer includes an internal sealed housing 52 that is mounted by a snap fit inside the rails and the beams surrounding each opening (Fig. 4). Preferably, the rails and beams are square metal tubes that are slidably retained in corner pieces 23. Each locking mechanism includes a male retainer which includes a drive arm 54 having a stub shaft latching member 56 at its free end and a fixed rotatable end being attached a camming unit made up of a rotor 58 and a cam 60 that provides prescribed motion to the free end of the drive arm as the arm moves between an unlocked stored position within the housing to a locked position in which the drive arm of the retainer has moved into the keyway 44 of a rail or beam 42 of an adjacent module, and the shaft has been placed in locking engagement against the surface of the beam or rail. When a pair of modules are properly positioned for locking, the T-shaped keyways of both modules are aligned to provide free travel for the moving stub shaft end of drive arm 54 from keyway 34 of rail 32 into keyway 44 of rail 42. Fig. 5 shows the two keyways in alignment prior to moving the two rails in contact for locking engagement. Fig. 6 shows the rails in locking alignment with the stub shaft 56 positioned in the narrow portion of the keyway 44 of rail 42.
Fig. 4 illustrates the locking mechanism in greater detail in the locked position in which the stub shaft 56 is exerting a compressive force on the internal inside wall of rail 42 of module 40 to draw the two adjacent rails into tight locking alignment.
In operation, the rotor 58 is turned by a suitable tool, such as an alien wrench 62, which activates a camming unit 60 contained within housing 52. The camming unit provides a prescribed motion to drive arm 54 when moved from the unlocked stored position within the housing 52. initially the stub shaft is raised out of its stored position into the guide opening in the adjacent keyway 44 and then laterally over the narrow section of the keyway. When fully positioned over the narrow section of the keyway, the shaft is drawn downward against the inside surface 43 of the rail on each side of the keyway to apply a high latching force to draw the two rails tightly together. The rotor/cam mechanism for the prescribed motion is readily commercially available in the art.
In order to avoid unwanted metal to metal contact between abutting modules, resilient seal means 64 are positioned between rails 32 and 42 which also aids in providing a tight seal when the modules are locked together. Compressible hollow seals 45 are mounted around the panel receiving opening. At panel closure, of the panel compresses the seals as shown in Fig. 4 to prevent air being conducted inside the unit from escaping around the panel.
While the present invention has been particularly shown and described with reference to the preferred mode as illustrated in the drawing, it will be understood by one skilled in the art that various changes in detail may be effected therein without departing from the spirit and scope of the invention as defined by the claims.
