Description
BACKGROUND OF THE INVENTION
This invention relates in general to sheel metal enclosures for air
conditioning equipment and deals more particularly with an
enclosure system which provides dimensional installation
flexibility and which may be prefabricated in a factory to be
quickly and easily assembled on the job, and yet provide an
architecturally pleasing appearance.
Problems arise during the installation of prefabricated metal
enclosures in buildings due to normal building tolerances between,
the floor, ceiling and the wall mounting surfaces. Difficulties
invariably arise at the job site when panel sections must be cut to
fit. The neat installation envisioned by the architect may not be
achieved due to the lack of attention to these tolerances on the
part of the enclosure designer.
The general aim of the present invention is to provide an enclosure
which incorporates an adjustable mounting system which would absorb
building tolerances in the area of installation.
Another aim of the invention is to provide a unique panel joint
system of cover battens and structural mullions which form a
convenient panel joint capable of assembly in the field, while
giving a custom architectural appearance after assembly.
SUMMARY OF THE INVENTION
In accordance with the present invention an enclosure is provided
wherein structural mullions are adjustably fastened, at spaced
locations to floor, ceiling or wall mounted support brackets. Sheet
metal panels are then supported by and fastened to the mullions by
a unique system of cover battens and spring clips.
The panel joining system, by means of which the panels are secured
to the mullions with cover battens in accordance with the present
invention comprises battens having finished outer surfaces, and
structural mullions fastened to the battens by spring clips, which
clips are adapted to releasably engage channels defined by the
mullions.
An adjustable mounting system is also provided by means of which
one end of each mullion is attached to the floor or ceiling mounted
support bracket and the other end to a wall mounted support
bracket. The floor or ceiling system utilizes an angle plate and an
anchor plate through which the mullion and bracket are joined by a
bolt and nut. A vertical slot in the angle plate allows the
structure to be anchored at the desired height above the floor. An
oblique slot in the anchor plate facilitates and helps hold the
height adjustment.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Turning first to FIG. 1, a wall and floor mounted enclosure is
indicated generally at 10. This enclosure includes an extruded wall
support bracket 20 which is fastened to the wall W and a floor
support bracket 40 secured to the floor F. Structural mullions 30
are bolted to these support brackets at spaced locations along the
length of the structure. The enclosure panels 50, 51 are set in
place and secured to the mullions by means of cover battens 33. The
battens in turn are held to the mullions by a number of spring
clips 34. The juncture of two adjacent enclosure panels such as 50
and 52 and also 51 and 53 determines the location of the mullions.
In this way a panel may be cut to any desired length and securely
fastened at its ends to mullions.
An alternate type of enclosure is indicated generally at 12 in FIG.
2. This enclosure 12 utilizes two wall support brackets 20 as shown
and requires no floor mounted brackets as shown at 40 in FIG. 1.
Mullions 30a are then battened to these supports 20 and the
enclosure is formed in much the same manner as the structure of
FIG. 1.
FIG. 5 illustrates a detailed cross section of the wall and floor
mounted enclosure of FIG. 1. Considering FIG. 4 in greater detail,
the wall support bracket 20 is seen to be of extruded metal, and is
fastened to the wall W by a number of screws 22 which pass through
a row of regularly spaced holes provided at intervals along the
length of the bracket and adapted for this purpose.
The support bracket includes a integral slotted channel 20a along
its top edge in which may be trapped a number of mullion mounting
bolts 24. The shanks of the trapped bolts project upwardly through
the slot thus allowing the bolts 24 to be positioned along the
length of the bracket for securing one end of the mullion 30 to the
bracket 20. The bracket 20 also includes a groove 20b from which
air conditioning equipment (not shown) can be conveniently
mounted.
A detailed cross section of the enclosure panel joint assembly is
shown in FIG. 3. Two adjacent panels 50 and 52 are set in place
atop the mounting flanges 31 and 32 of the mullion 30. A cover
batten 33 is then supported into the mullion channel 30a by means
of spring clips 34 thereby anchoring the panels in position by
forcing them against the mullion flange.
The battens are more particularly joined to the mullions by these
spring clips 34, which spring clips are forced into and releasably
retained within the mullion channel 30a. A number of these clips
are fastened to each batten by bolt means in the form of threaded
screws and nuts, 36 and 37 respectively. The heads of these bolts
are retained within a channel 33a which is integral with the rear
wall of the batten and which extends the length of the batten. The
shanks of the bolts protrude through a slot in the rear wall of the
channel thus permitting the bolts to be moved within the channel
for positioning anywhere along the length of the batten. In this
way a suitable number of clips may be spaced as needed along the
length of the batten to insure a strong joint between it and the
mullion.
The above described enclosure joint construction is well suited for
joining panels of various geometric configurations. The enclosures
shown in FIGS. 1 and 2 illustrate two presently preferred
embodiments, but other enclosure shapes might also be devised to
take advantage of the joint shown in FIG. 3. In addition, the joint
structure of FIG. 3 may assume alternate configurations. Two such
configurations are shown in FIGS. 8 and 9. Both of these
configurations can utilize a mullion having a rectangular channel
and in the case of FIG. 8 the spring clip 34 has been eliminated
and the bolt 36a allowed to pass through the base of the mullion
channel and to be releasably retained by a wing nut 37a. The
configuration of FIG. 9 avoids the use of a bolt by directly
entrapping the head portion of the spring wire clip, the leg
portions of which pass through holes in the mullion channel to
secure the clip therein.
Referring more particularly to the FIG. 5 enclosure shape, the
mullion 30 is formed from several straight sections, or portions
which portions may be welded or otherwise connected at the corners
A and B to provide the generally L-shaped frame of FIG. 5. The
batten 33 is then bent to shape as required, and provided with the
spring clips 34 at selected locations to permit the final assembly
on site.
In the FIG. 5 enclosure the top mullion portion supports at least
one top panel 50, and said top panel may include a depending flange
50a for supporting a louvered insert panel (not shown). The
enclosure of FIG. 5 also includes at least a front panel 51 which
is bent at the corner A to provide a horizontally oriented top
segment 51a and a vertically oriented front segment 51b. The top
segment has a depending flange similar to that shown at 50a to
support the louvered insert panel.
FIGS. 6 and 7 illustrate the means by which the enclosure is
adjustably mounted on the floor support bracket 40. The extruded
floor support bracket 40 is fastened to the floor F by convenient
means as for example by the wood screws 41 which pass through
regularly spaced holes in the lower leg of the support. Thus
mounted the upper leg of the support is generally vertical with
respect to the floor and forms a base and kick-space under the
enclosure.
A slotted rearwardly opening channel 40a is integrally formed along
the top edge of the vertical support bracket leg. This channel 40a
is adapted to receive and retain the heads of a number of mullion
mounting bolts 46. The slot in the rear wall of the channel permits
the shanks of the bolts to protrude rearward and permits the bolts
to be moved within the channel to any desired location along the
length of the support bracket 40.
The lower end or return leg of the mullion 30 is oriented
horizontally and at right angles to the floor mounted support
bracket 40. This return leg is fastened to the floor support
bracket by means of an angle plate 44, and an anchor plate 42. The
angle plate is permanently joined, by one of its legs, to the end
of the mullion either by spot welding or other suitable means. The
other, or depending leg of the angle plate extends downwardly and
has a vertically elongated slot 44a. The slot 44, best shown in
FIG. 7, is adapted to permit the shank of the mounting bolt 46 to
pass through the angle plate and to be vertically adjustable
therein. The bolt is then secured by a nut 47.
The anchor plate 42, when installed, is trapped between the angle
plate 44 and the rear wall of the slotted channel 40a. The lower
edge of the anchor plate is set in a groove 40b which is integrally
formed in the lower leg of the floor support bracket 40 and which
extends along the length of the bracket. The entrapped upper
portion of the anchor plate includes an obliquely oriented slot 42a
adapted to allow the shank of the mounting bolt 46 to pass through
the anchor plate before passing through the vertical slot in the
angle plate 44.
The vertical slot 44a in the angle plate 44 allows the height of
the enclosure to the floor support bracket to be adjusted to
accommodate any building tolerances between the floor and wall. The
oblique slot in the anchor plate facilitates and holds this height
adjustment without having to overtorque the nut 47, or use lock
washers or the like.
The adjustable floor mounting system first described may also be
utilized in the ceiling mounted enclosure illustrated in FIG. 10.
As shown, the components of the ceiling mounted application are
identical as is the adjustment procedure.
Still another application of the adjustable mounting system is
shown in FIG. 11 which illustrates a free-standing floor mounted
enclosure. In this case two sets of components are utilized to
adjust the height of the structure above the floor. This also
allows the enclosure to compensate for a sloping floor by
maintaining a level appearance.
