Description
BACKGROUND OF THE INVENTION
At the present time a substantial number of homes and other
buildings are provided with pairs of sliding panels or doors, each
of which comprises generally a frame in which is mounted plate
glass, sliding panels of this general character in many instances
open onto patios and the like.
In a closure arrangement comprising a pair of sliding panels where
one of said panels is in locked, closed position, substantial
difficulties have been encountered in providing easily accessible
and operable means for locking the other sliding panel in closed or
partly open position. It will be recognized that locking means of
some character is essential in order to bar unauthorized access to
the structure which is closed by the closure means.
A locking means of the character broadly outlined above must be so
constructed and designed that it is not only accessible and may be
operated with facility, but it must also be so configured and
constructed that it may be affixed with substantially no difficulty
on the panel of the pair of panels which is in closed locked
position.
SUMMARY OF THE INVENTION
While I have illustrated this invention combined with sliding panel
closure means which slide in a horizontal plane, it must be
appreciated that the invention is applicable to window sashes, and
the like, which slide in a vertical plane, and while I shall
describe this invention as providing locking means for the outer
panel of a pair of sliding panels it is within my contemplation to
adapt this locking means to the inner panel of a pair of sliding
panels, or sashes. In a pair of sliding panels within the purview
of my invention, the panel which may be either the outer or inner
panel and when in closed position is in abutment against a vertical
frame of the opening, is utilized for affixation thereto of the
locking mechanism which co-acts with the other panel, whether an
inner or an outer panel, to lock the same in closed or partly open
position.
One of the significant purposes of this invention is to simplify a
locking arrangement for one of a pair of sliding panels, and as the
description proceeds it will become apparent that the locking
mechanism which I have devised may function with equal facility on
either the inner sliding panel or the outer sliding panel. The
basic concept which enables me to use the same locking mechanism
for locking either the inner or the outer sliding panel, comprises
the utilization of the stationary or closed panel of the pair of
panels as the means which functions through the locking mechanism
to lock the other panel in fully closed or partly open
position.
Of further significance is the panel structure itself and the
operating arrangement of the locking mechanism which is designed
for relatively simple and easy mounting on the panel of a pair of
panels which is in closed or stationary position so that the
locking mechanism is co-active with the other panel and is manually
adjustable to lock the other panel in closed or partly open
position.
It is highly desirable that the locking mechanism be so affixed to
the closed or stationary panel as to be co-active with a certain
and specific area of the frame of the other panel which is to be
locked in fully closed or partly open position. This particular
positioning of the locking mechanism relative to the panel to be
locked is desirable and advantageous in the addition to the entire
arrangement of substantial strength characteristics. The
application of the locking mechanism to the sliding panels causes
no weakening of the entire combination.
As will become clear in the following detailed description of my
invention, certain structural characteristics of the sliding panels
have been taken into consideration in the particular structure and
configuration of the locking mechanism so that this structure of
the panels will not be damaged by the affixation thereto of the
locking mechanism, and yet the locking mechanism will co-act at the
desired positions on the panel to be locked in closed or in partly
open position.
With the foregoing general objects, features and results in view,
as well as certain others which will be apparent from the following
explanation, the invention consists of certain novel features in
design, construction, mounting and combination of elements as will
be more fully and particularly referred to and specified
hereinafter.

DESCRIPTION OF THE INVETION
In the accompanying drawings I have used the numeral 1 to designate
generally one panel of a pair of sliding panels and the numeral 3
to designate generally the other sliding panel of the pair of
sliding panels. Such panels 1 and 3 are slidably operable within
the usual horizontal frame 5 and vertical frame 7, both of which
are fixed members. Since in FIG. 1 of the drawings parts thereof
are broken away, only the upper section 5 of the frame is
illustrated and only one vertical section 7 thereof is illustrated.
As is conventional, the panels 1 and 3 slide in laterally spaced
guide tracks (not shown), which are provided in the horizontal or
upper and lower sections 5. The panel 3 is provided with a vertical
frame member 9 and an upper horizontal frame member 11 which is
fixed to the vertical frame member 9 by means of a screw or the
like 13. It will be recognized that there is also a rear vertical
frame in the panel 3 which is similar to the vertical frame 9 and a
lower horizontal frame which is similar to the upper horizontal
frame 11. The sliding panel 1 is also provided with a framework
generally similar to that provided for the panel 3, the upper
horizontal panel 15 being shown in the drawing. Plate glass or the
like 17 is mounted within the framework of each sliding panel.
Merely by way of example, and not as a limitation, I have
illustrated the sliding panel 1 as being the outer panel of the
pair of panels and the sliding panel 3 as comprising the inner
panel of the pair of panels.
The locking mechanism comprises a base designated in its entirety
by the numeral 19 and this base consists of a pair of plates 21 and
23 which are combined at substantially right angles to one another,
as is clearly illustrated in the drawings. The plates 21 and 23,
which form the base of the locking mechanism, may be integrally
formed or may be attached together in any suitable manner, as by
welding. The plates 21 and 23 are preferably though not necessarily
dimensionally similar. Fixed to the plate 23 of the base 19, in any
suitable manner, is a sleeve, barrel or the like 25, the sleeve 25
being provided with a bayonet slot 27 therein for a purpose which
will be hereinafter described. The sleeve 25 is mounted on the
exterior side of the plate 23 in position thereon with respect to
the upper edge 29 of the plate 23, so that the upper arcuate edge
31 of the sleeve 25 is slightly above a horizontal plane projected
from the edge 29 of the plate 23. The purpose of this relative
positioning of the sleeve on the plate will become apparent as this
description proceeds. Operatively mounted within the sleeve 25 is a
locking pin 33 which is of greater length than the length of the
sleeve so as to provide portions 35 and 37 extending beyond the
ends of the sleeve 25. Affixed to and extending radially from the
locking pin 33 is a pin 39 which, as will be explained, is operable
within the bayonet slot 27. Fixed to the extending portion 37 of
the locking pin 33 is a knurled operating head 41. The locking pin
33 is movable axially and is rotatable in the sleeve within the
limits defined by the bayonet slot.
The upper horizontal frame 15 of the openable panel 3 is provided
with a series of spaced-apart holes 43 therein. These holes, as
will be explained are provided to receive the extending locking
portion 35 of the pin 33. The openings 43 in the horizontal frame
15 do not extend entirely through said frame and it is important
for a variety of reasons that these openings 43 be positioned
substantially intermediately of the transverse dimension of the
frame 15.
The locking mechanism 19 is mounted on the vertical frame 9 of the
stationary panel 3, the plate 21 of the base of the locking
mechanism is attached to the vertical frame 9 by means of a screw
or the like 45. Consideration particularly of FIG. 1 of the
drawings indicates that the locking mechanism is affixed to the
vertical frame 9 in position below and not covering the screw 13
which is utilized in the construction of the panel 3. This
particular disposition of the locking means is of significance for
it is undesirable to cover the screw 13.
The other plate 23 of the locking mechanism is secured to the
vertical edge 47 of vertical frame 9 of panel 3 by means of a screw
49, and it will be observed that the width of the plate 23 is
substantially equal to the width of the edge 47 of the frame so
that no portion of the plate 23 extends beyond the edge 47.
With the locking mechanism mounted as described it will be
recognized that the extending locking portion 35 of the pin 33,
when the pin is projected extends beyond the edge of the frame 47
and is operable to be received in any one of the openings 43 in the
horizontal frame 15 of the panel 1. In order to withdraw or retract
the locking extension 35 into the sleeve 25 the knurled operating
head 41 is grasped and rotated to the right as FIG. 3 is viewed, so
that the pin 39 is moved from the transverse locking portion of the
bayonet slot, whereupon the operating head 41 is moved producing
axial movement in pin 33 until the pin 39 reaches the end of the
longitudinal portion of the bayonet slot. In this position the
locking portion 35 is retracted into the sleeve 25 and the sliding
panel 1 may be opened. When it is desired to lock the sliding panel
1 in closed position the reverse action is followed by using the
operating head and disposing the pin 39 in the transverse portion
of the bayonet slot to thereby project the locking extension 35
into the end hole of the holes 43. In this position the panel 1 is
soundly locked in closed position and may not be moved to open
position in the direction of the arrow since in order to accomplish
this the panel 3 would have to be moved in the direction of the
arrow on it, and this cannot be accomplished in view of the
abutment of a vertical edge of the panel 3 against the fixed
vertical frame member 7, making panel 3 immovable in the direction
of the arrow. In order to maintain and lock the panel 1 in certain
partly open positions, the locking extension 35 is retracted from
its hole 43 and the panel 1 is slid in the direction of the arrow
until one of the desired other holes 43 is in line with the
extending locking pin 35 so that it may be projected into such
hole.
Since the holes 43 must be positioned midway of the transverse
dimension of the frame 15 and since the extending locking pin 35
must be in line with these holes, and in order to position the base
of the locking mechanism so that the screw 13 is not covered, the
upper arcuate surface of the barrel 25 must be positioned slightly
above a projected horizontal plane of the upper edge 29 of the
plate 23.
It is within my contemplation to position the locking mechanism
which has been described above at the bottom rather than the top of
the frames of the sliding panels. It will also be appreciated since
the openings 43 are positioned intermediate the longitudinal edges
of the frame 15 that the locking pin 35 will operate not only in
the center of frame 15 but also in the center of frame 11.
