Description
FIELD OF THE INVENTION
The present invention relates to runners, more particularly the
present invention relates to a floor or ceiling runner for
accommodating panels of movable gypsum partitions.
DESCRIPTION OF THE PRIOR ART
Conventional gypsum partitions are erected using a ceiling runner
which is normally a channel-shaped member into which the top end of
the gypsum panel forming the partition is inserted and a floor
runner which is a channel member that embraces the bottom of the
partition panel. With these types of runners, it is necessary to
insert the panel into a top runner and then drop it in the bottom
runner necessitating that the top runner have flanges longer than
those of the bottom runner so that the board may be inserted and
dropped and still be retained by the top runner. This inherently
means that the panel must be considerably shorter than the spacing
between the ceiling and floor to permit erection.
It has also been proposed to use a two-piece floor runner so that
the partition panels can be substantially the same height as the
floor to ceiling dimension. Such runners are substantially channel
shape but one flange is considerably shorter than the other so that
the panel may be pivoted over the top of the shorter flange into
abutment with the longer flange. This particular type of
construction requires a filler strip to be inserted into the bottom
channel to occupy the height of the shorter flange. After the panel
is erected a closing strip is secured to the short flange to retain
the panel. This type of construction requires extra filler strips
and a further time consuming operation of securing the closing
strip to the short flange of the runner. Such an arrangement is
shown for example in Canadian Patent 670,417, issued Sept. 10,
1963, to Kaari and Canadian Patent 713,248 issued July 13, 1965, to
McGill.
It is the object of the present invention to provide a simple
runner structure permitting the use of substantially full height
panels while facilitating erection and locking of the panel in
position.
SUMMARY OF THE INVENTION
Broadly the present invention comprises a runner structure formed
of an elongated L-shaped member one arm of which has gripping means
adjacent its free end, a plurality of cooperating L-shaped locking
elements each having one arm provided with a gripping means adapted
to cooperate with the gripping means on the elongated L-shaped
member cooperate with the elongated member to secure a panel in
position.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
As shown in FIG. 1, the runner structure 10 basically includes a
continuous runner member 12 which generally will be sold in 8 or 10
foot lengths together with discrete locking elements 14 which
normally will be less than 1 foot and preferably about 2 to 4
inches in length and will be provided on the average about every 1
to 3 feet. More or fewer elements may be provided as required.
The continuous runner 12 is provided with a holding flange 16 and a
base flange 18. The flange 16 adjacent its connection to the basic
flange 18 is preferably provided with a curved section 20 which
curves inwardly toward the longitudinal axes of the panel. This
section 20 is adapted to resiliently press against the face of the
panel to better hold the panel in position. A curved projecting
section 22 curves outwardly from the section 20 and terminates at
the free end of the flange 16 and is adapted to cooperate with a
base board or the like member as will be described further
hereinbelow.
The base flange 18 preferably has a pair of spaced parallel ridges
24 and 26 located on opposite sides of the longitudinal centre line
of the partition and extending through the flange 18 are a
plurality of apertures 28 which are adapted to receive fastening
means for securing the continuous runner member 12 to thie floor or
ceiling. The free end of the base flange 18 of the continuous
runner member 12 is reverse folded so that the free edge 19 of the
flange 18 faces toward the centre line of the partition and is
located on the side of flange 18 remote from flange 16 thereby to
provide a gripping section 30. This gripping section 30 is bent
upwardly out of the plane of the flange 18 in the same direction as
the ridges 24 and 26 but does not extend above the height of the
ridges 24 and 26.
The discrete locking elements 14 each comprise a folding flange 32
formed with curvatures 20 and 22 equivalent to those described
hereinabove with respect to the flange 16 (see FIG. 3) and with a
locking flange 34 having a mating gripping section 36 adapted to
cooperate with the gripping section 30 on the flange 18. Gripping
section 36 in the illustrated arrangement simply takes the form of
a reverse fold adjacent the free edge of the flange 34 so that the
free edge 37 of the flange 34 faces the flange 32 and is located
between the flange 32 and 34.
In operation the elongated runner members 12 are first secured in
position by fastener elements 38 extending through the apertures 28
and then wall panels 40 are moved laterally into position (see FIG.
5). The panels 40 may be mounted in the conventional manner at the
top or at the bottom or both the top and bottom ends of the panel
may be mounted using the present invention. When the panel has been
positioned the locking elements 14 are moved into position and the
locking flange is forced under the panel 40 whereby the gripping
section 36 moves under the gripping section 30 until the free ends
19 and 37 snap into position in face-to-face relationship as shown
in FIG. 4.
In the preferred embodiment the holding flanges 16 and 32 are
resiliently deflected, i.e. the curved sections 20 engage the
opposite faces of the panel 40 and thus resiliently hold the panel
in position. This resilient engagement between the curved sections
20 and the faces of the panel 40 is not absolutely essential to the
operation particularly if a sealant such as that indicated at 42 is
provided in the runner member 12 (see FIG. 5).
After the locking elements 14 have been positioned in the manner
above described, suitable molding members such as the baseboards 50
are applied. As shown, each of the baseboards 50 is provided with a
downwardly projecting flange 52 that is received between the curved
sections 22 and the panels 40 and is resiliently held in this
position by the sections 22.
As above indicated, the ridges 24 and 26 are not absolutely
essential to the operation of the device but are preferred. In some
cases, depending on the thickness of the metal from which the wall
holder is made and the location of the screws 38, these ridges 24
and 26 may be omitted. Similarly, as above indicated, the curved
sections 20 are not absolutely essential. If desired, one could
replace the curved projecting section 22 with other suitable means
for mounting the baseboard or other molding.
The locking sections 30 and 36 have been shown as the reverse
folded sections adjacent the free ends of the flanges 18 and 34. It
will be apparent that one of these reverse folded sections 36 need
not be closed tightly, i.e. the bent-over flange could extend at an
acute angle from the flange 18 or 32 rather than being
substantially parallel thereto. It is believed to be important that
at least one of the gripping sections 30 or 36 be formed with a
tight fold so that the bent-over flange is in face-to-face
relationship with its respective flange 18 or 32.
Should it be necessary to dismantle the wall for one reason or
another, it is a relatively simple matter. First, the baseboard 50
held in position by the locking elements 14 is removed and then the
locking elements 14 are removed by simply inserting a screwdriver
or the like under the locking section 30 on the flange 18 and
lifting the section 30 so that the free edge 19 thereof clears at
least the adjacent corner of the free edge 37 of the section 36 so
that the element 14 may be twisted on a vertical and pulled out. In
some cases, it may be possible to lift the flange 18 and thus the
locking element 30 sufficiently to completely free the edges 19 and
37 and permit the element 14 to be withdrawn perpendicular to the
wall but normally it will be removed by a twisting action. After
the elements 14 have been removed the panels is free and may be
easily removed.
While the description has primarily dealt with a bottom runner,
obviously the structure could equally well apply to a top runner.
When used as the bottom runner the weight of the panel may press on
the locking sections 30 and 36 and help to maintain the lock.
Modifications may be made without departing from the spirit of the
invention as defined in the appended claims.
