Description
BACKGROUND OF THE INVENTION
For many years, closure members have been constructed with the
handle or bail of the pull being recessed into the closure member.
U.S. Pat. No. 856,214 is an example of such a construction. The
difficulty with the conventional mounting of such handles or bails
has been that the pull is assembled by a tedious attachment of the
bail in a pivotable manner to the closure member. For example, in
the aforesaid U.S. patent, the bail 3 is pivotally attached by a
bolt 12 to ears or lugs 13 mounted within the closure member (i.e.,
the door). Such bolting procedures delay the assembly and thereby
add to the cost of manufacturing.
A further disadvantage arises when such recessed handles are
utilized in connection with a remote control latch. That is, the
presence of a spring such as the spring 5 in the aforesaid U.S.
patent exerts a force either constantly or during actuation of the
type which could cause the handle to unseat if it is not securely
fastened. It will be readily appreciated that a design which
permits easy assembly without the use of bolts, etc., would also
tend to permit ready disassembly such as by accident. Accordingly,
construction of remote control latching mechanisms heretofore has
not featured a handle or bail assembled other than by pivotally
holding or otherwise restricting the movement of the handle or pull
within the closure member.
Recently, steps have been taken to partially alleviate the assembly
problem, at least in the case of a simple recessed bail or handle.
Thus, U.S. Pat. No. 3,451,590 illustrates a bail which is snapped
into the pivot openings 25 and 26. However, it will be appreciated
that even this assembly procedure takes time because of the
necessary alignment of the lugs or pintles with the openings.
Furthermore, U.S. Pat. No. 3,451,590 does not teach how such an
arrangement could be used with a remote control latch.
SUMMARY OF THE INVENTION
This disclosure relates to a recessed bail and a remote control
latching mechanism utilizing the same for use in a closure member
such as a drawer front, a door, a window frame, or the like.
Specifically, there is provided an improvement in a closure member
having a vertically extending panel with an opening for receiving a
recessed pull assembly which includes a pivotally supported bail
mounted in a manner to permit grasping the bail from a position in
front of the enclosure. The improvement comprises the recessed pull
assembly having a slot especially adapted for dropping the bail
thereinto from a position generally above the same, means being
provided for mounting the assembly in the opening so that the panel
blocks the bail from movement out of the slot.
This improved closure member makes possible a novel remote control
latching mechanism assembled so that a biasing means exerts a force
in a vertically upward direction which would normally tend to force
a bail upwardly out of the portion, but which is prevented from
doing so because of the assembly thus instead biasing the latch
into latch position.
Accordingly, it is an object of the invention to provide a closure
member having a recessed handle or bail and a remote control
latching mechanism using the same which is characterized by ease
and quickness of assembly of the handle within the closure
member.
It is a related object of the invention to provide such a recessed
pull assembly and a remote control latching mechanism wherein the
assembled bail or handle is prevented from disassembly either by
the user or by the remote control latching mechanism.
Still another object of the invention is to provide such a recessed
bail and operating mechanism for a closure member and remote
control latching mechanism which is inexpensive to manufacture and
assemble.
Other objects and advantages will become apparent upon reference to
the following drawings and detailed discussion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
The disclosure concerns a recessed pull for closure members, which
pull can be modified for use in a remote control latching
mechanism. By "closure member" as it is used throughout the
application, it is meant any member 10 (FIG. 1) which can be used
to close an opening, such member including a drawer front, a door,
a window frame, and the like. Referring specifically to FIGS. 1
through 3, the closure member 10 includes generally a vertically
extending panel 12 having an opening 16 forming a well-shaped
recess 14 therein. The recess can have an open top as shown in the
drawings, or it can be completely enclosed except for the opening
16. That opening is partly defined by the edge 18 formed by the
panel 12. The bottom of the recess is provided with holes 20 to
accommodate bolts as hereinafter explained.
In accordance with one aspect of the invention, there is provided a
pull assembly 30 which pivotally mounts a bail 50 in a manner
hereinafter described, the bail being assembled by dropping it
through a slot 38 in the top of the pull assembly. The pull
assembly 30 has an outwardly facing decorative edge 32 and a
recessed portion 34 designed to be recessed within the panel 12.
The recessed portion 34 has a top surface 36 which may be
completely open as indicated in FIG. 4, or which may be closed,
with the exception of the slot 38 which is especially adapted to
permit the bail 50 to be dropped into place within the pull 30 from
a position above the recessed portion 34. Shoulders 40 are provided
at the edges of the recessed portion 34 of the pull, the shoulders
serving to support the bail 50 on its pintles 52. (See FIG. 4.) The
back surface 42 of the recessed portion 34 is provided with
threaded holes 44 to accommodate bolts 46 by which the pull 30 is
mounted within the recess 14.
Turning now to the bail 50, the bail has pintle portions 52 at the
sides thereof preferably located near the top, the pintles resting
upon the shoulders 40 for permitting the bail to pivot outwardly
within the pull. The bottom edge 54 of the bail is the conventional
grasping portion by which the bail is pulled outwardly to open or
close the closure member.
As shown in FIG. 5, the pull and the bail are assembled in the
following fashion: the bail 50 is first dropped into the pull 30 by
positioning the bail above the pull. The bail simply drops through
the slot 38 so as to rest the pintles 52 upon the shoulders 40. The
assembled bail and pull are then slid into the well 14 from a
position in front of the panel 12. Bolts 46 hold the bail and pull
in this assembly recessed within the closure member 10, the edge 18
of the panel 12 serving to thereafter prevent the bail 50 from
being pushed upwardly out of the slot 38 of the pull 30 (FIG.
3).
FIGS. 6 through 11 illustrate an alternate embodiment wherein the
recessed pull is modified so as to act as a remote control latching
mechanism. Parts similar to those previously described bear the
same reference numeral to which the distinguishing suffix "a" has
been added. Thus, the same recessed pull 30a is mounted within a
closure member 10a (FIG. 6) with a bail 50a dropped into position
in the slot 38a in the top of the recessed portion 34a of the pull.
(See FIG. 10.) Unlike the previous embodiment, the bail 50a has
been modified so that one of the pintles 52a has an ear 60 (FIG. 9)
projecting outwardly from the bail as an extension of the pintle,
the ear being adapted to abut against a connecting means for
operating a latch 90 (FIG. 11). The connecting means comprises a
bell crank 62 (FIG. 7) having two arms 64 and 66, the arm 66 having
a portion 68 bent out of the plane of the crank 62 so as to contact
the ear 60 below the same. The arm 64 is pivotally attached near
one end 70 thereof to the latch 90, the attachment being by means
such as a bolt. To bias the portion 68 of the arm 66 against the
ear 60, a coil spring 72 is included, the spring having a leg 74
hooked over the arm 64 of the bell crank, and a leg 76 abutting
against a stop portion 78 on the back surface 42a of the pull 30a
(FIGS. 7 and 9). The stop 78 can take any form, the form shown
being a stud screwed into the surface 42a. Another form could be a
rib extending the full height of the back surface 42a.
Both the spring 72 and the bell crank 62 are mounted upon a stud 80
which is attached to a back plate 82 (FIGS. 7-9). The back plate in
turn is mounted on the back 42a of the pull 30a by screws 83. The
stud 80 has a shoulder 84 which holds the crank 62 in position,
while the spring 72 may be held on the stud 80 prior to assembly by
means such as a washer or the like (not shown). In addition to
mounting the bell crank 62 and the spring 72 as a unit, the back
plate 82 has an additional function. That is, the back plate can
take any shape except that it should be L-shaped with a leg 86
extending over the top of the recessed pull 30, thereby providing a
blocking surface 88 which prevents the bail 50a from being forced
upwardly out of the slot 38a (FIGS. 8-10) by the action of the
spring 72 biasing the arm 68 of the crank against the ear 60. This
function of the back plate 82 permits the entire recessed pull 30a
with the bail and the connecting means assembled therein to be
mounted within the closure member as a unit, the latch 90
thereafter being attached to the end 70 of the bell crank such as
by bolting as mentioned before. With regard to the latch 90, it
should be noted that it can take any shape, preferably having a lip
92 which engages the frame within which the closure member 10a is
positioned to latch the same.
The assembly of the remote control latching mechanism shown in
FIGS. 6 through 11 is accomplished in a manner similar to that of
the previous embodiment. That is, the pull and the bail assembled
together along with the contacting means and the back plate 82 are
slid into the opening in the closure member 10a from a position in
front thereof. The closure member 10a may have a U-shaped strap 100
(FIG. 8) or a well-shaped recess as shown in the previous
embodiment. In either case, there is provided an opening for
bolting the strap by means of the bolts 46a which bolts thread into
the threaded holes 44 of the recessed portion 34a (FIGS. 7 and
10).
The materials used in both of these embodiments can be varied,
synthetic plastics and metals being the most common forms. Thus,
the pull 30, the bail 50, and the back plate 82 can comprise a
plastic material such as ABS (acrylonitrile-butadiene-styrene)
plastic.
It will be readily appreciated that both of these embodiments
feature ease of assembly due to the slot in the top of the recessed
portion 34a which accommodates the bail by simply dropping the
latter into the pull. It is this ease of assembly which would also
permit easy accidental disassembly, which accidental disassembly is
prevented by, in the first embodiment, the edge 18 of the panel 12,
and in the second embodiment, also by the top portion 86 of the
back plate 82. The second embodiment has the additional advantage
of simplification by forming the ear 60 as an extension of one of
the pintles 52a. Such simplification in manufacturing reduces the
cost of the entire remote control latching mechanism.
Although the invention has been described in connection with
several preferred embodiments, it is not intended that it be
limited thereto. Rather, it is intended that it cover all
embodiments, equivalent arrangements, and alternate forms as may be
included within the scope of the following claims.
