Description
BACKGROUND OF THE INVENTION
The present invention relates to a stackable chair kneeler and more
particularly to a kneeler mounted on a chair which may be stored
with other chairs of similar construction in vertical stacks.
Church kneelers are used to provide a raised cushion for members of
the congregation when kneeling during certain portions of the
services. Such kneelers are usually mounted with freedom of
swinging movement between an active horizontal position and an
inactive upright position. During the church services, it becomes
necessary from time to time to swing the kneelers from one position
to the other, and vice versa. Such devices are typically in the
form of cushioned benches provided with arms arranged to be
pivotally connected to vertical supports mounted on the backs of
pews to permit their being easily moved to a lower position of use
and to an out-of-the-way position of nonuse so as to provide
walking space between the pews.
It has often become necessary and convenient in modern churches to
use individual stackable chairs rather than long pews for services.
Such chairs may be moved from a sanctuary to other portions of the
church and used for non-ecclasiastical purposes. When not in use,
such chairs may be vertically stacked for convenient storage. In
order to use stackable chairs for services, it has become necessary
to provide kneelers mounted on the backs of the chairs. Prior art
kneelers for individual chairs have typically proven not to be
adapted for use on stackable chairs because of interference with
the stacking configuration. Furthermore the complexity of such
previously known kneeler constructions does not lend itself to
chairs which are permanent in shape and vertically stackable.
SUMMARY OF THE INVENTION
The general purpose of the present invention is to provide a
kneeler for a stackable chair having a padded horizontal portion
mounted on a kneeler frame. The kneeler frame is pivotally attached
to a U-shaped subframe and is swingable between a down position
wherein the padded portion may be knelt upon and a retracted
position wherein it is releasably held by detents in coplanar
alignment with the U-shaped subframe.
In the preferred embodiment, the kneeler frame is also U-shaped.
The subframe is provided with spring loaded retractable studs
engageable in suitable holes drilled in the frame. In this
embodiment, therefore, the subframe may be secured in an operative
position in coplanar alignment with the rear legs of the chair, or
in a storage position lying just beneath the seat of the chair. The
studs are slidable in the cross bar of the subframe and are
retracted by means of upstanding members which protrude through
suitable slots formed in the cross bar.
In an alternative embodiment, the kneeler frame is rectagular in
shape. The spring loaded retractable studs are mounted on a cross
bar of the kneeler frame and through both sides bars of the
U-shaped subframe to hold the subframe in coplanar alignment with
the rear legs of the chair. In this embodiment, the subframe may be
held in the storage position by suitable detents.
A pair of short legs project at an angle from the kneeler frame in
either embodiment. These legs provide support when the frame is in
the down position. The legs do not interfere with ordinary use of
the chair either when the kneeler is retracted or when the entire
assembly is swung up into the storage position. Ears are mounted on
the subframe to limit the upward swinging movement of the kneeler
frame so that it will halt at the retracted position.
Accordingly, an object of the present invention is to provide a
kneeler for stackable chairs.
Another object of the present invention is the provision of spring
loaded retractable studs mounted on a chair kneeler apparatus for
retaining the kneeler in a desired position.
A further object is to provide a U-shaped kneeler for stackable
chairs having a subframe with spring loaded retractable studs for
selectively retaining the subframe in an operative position in
coplanar alignment with the rear legs of the chair or in a storage
position just beneath the seat.
Still another object is the provision of a rectangular shaped
kneeler for stackable chairs having spring loaded retractable studs
mounted through the side bars of a U-shaped subframe for releasably
retaining the subframe in coplanar alignment with the rear legs of
the chair.
Yet another object of the present invention is the provision of
detent means formed on a subframe operative in conjunction with a
rectangular shaped kneeler frame for retaining the kneeler and
subframe in a storage position.
Other objects, advantages and novel features of the present
invention will become apparent from the following detailed
description of the invention when considered in junction with the
accompanying drawings.

SUMMARY OF THE INVENTION
Referring now to FIG. 1, there is shown a stackable chair kneeler
10 constructed in accordance with the present invention having a
kneeler frame 11 swingably mounted on a subframe 12 which is held
by spring loaded retractable studs 13 and 14 in either an operative
position in coplanar alignment with rear legs 16 and 17 of
stackable chair 10 or in a storage position (shown in phantom in
FIG. 3) just beneath the chair seat 18.
In the embodiment shown in FIG. 1, the kneeler frame 11 is
U-shaped, having crossbars 21 and 22 and a padded horizontal
portion 19. The kneeler frame further has short legs 23 and 24
which project at an angle from the plane of the kneeler frame 11 to
provide supports therefor when the frame is in the down position as
shown in FIGS. 1 and 3. When the kneeler frame 11 is retracted into
coplanar alignment with rear legs 16 and 17 as shown in FIG. 4, the
short legs 23 and 24 are out of the way and do not interfere with
ordinary use of the chair. When the kneeler frame is swung up to
the storage position, the short legs 23 and 24 are in coplanar
alignment with the rear legs 16 and 17 as shown in FIG. 2. The
short legs are therefore out of the way in the storage position as
well.
The kneeler 11 is connected to subframe 12 for swinging movement
between its operative and storage positions, by pivot pins 26 and
27 and here is releasably held in coplanar alignment with the
subframe 12 by suitable detents 28 and 29 engageable in holes or
recesses suitably placed on the subframe. The kneeler frame may
thereby be held in either coplanar alignment with the rear legs 16
and 17 of the stackable chair 10 as shown in FIG. 4 or in the
storage position lying just underneath the seat 18 as shown in
phantom in FIG. 3.
The U-shaped subframe 12 is swingably connected to the chair legs
16 and 17 by pivot pins 33 and 34 as shown in FIG. 4. The
retractable studs 13 and 14 engage in suitable holes, drilled in
the rear legs 16 and 17 respectively, to hold the subframe in
coplanar alignment with the rear legs 16 and 17. The studs 13 and
14 are advanced and retracted by upstanding members 31 and 32 which
protrude through suitable slots in the crossbar 35 of U-shaped
subframe 12 to permit the subframe to be swung into the storage
position shown in phantom lines in FIG. 3. Studs 13 and 14 are
urged outwardly by a spring 35 contained in crossbar 35 for
selective engagement in suitable recesses formed in the front legs
of the chair 10 to retain the subframe 12 in the storage
position.
Shoulder members 36 and 37 mounted on subframe 12 limit the upward
swinging movement of the kneeler frame 11 to halt it in the
retracted position where it is releasably held by detents 28 and 29
which engage holes 25 and 30 respectively. the kneeler frame 11 is
thereby retained in coplanar alignment with the subframe 12 when
the subframe is either in coplanar alignment with the rear legs 16
or 17 or in the storage position directly beneath the seat 18. The
subframe 12 has shoulders 40 and 45 mounted thereon to limit the
downward swinging movement of the subframe so that it will halt in
coplanar alignment with the rear legs 16 and 17.
In the embodiment shown in FIG. 5, the kneeler frame 38 is
rectangular in shape and has spring loaded retractable studs 39 and
41 held through a crossbar 42 on the kneeler frame 38. The studs
are mounted through the side members of a U-shaped subframe 43 and
urged in the expanded position by a spring 44 which loads the studs
as shown in FIG. 6.
The subframe 43 is halted from swinging outwardly beyond coplanar
alignment with the rear legs by shoulders 66 and 67. Studs 39 and
41 with mating holes 46 and 47 respectively hold the subframe 43 in
coplanar alignment with the rear legs of the chair. The subframe is
pivotally connected with rear legs 48 and 49 by pivot pins 51 and
52 respectively. The kneeler frame 38 may be retracted into
coplanar alignment with the subframe 43 as shown in FIG. 6 and
retained in that position by detents 53 and 54 mounted on opposite
sides of the U-shaped subframe 43 as shown. Shoulder members 56 and
57 on the U-shaped subframe 43 limit the upward swinging movement
of the kneeler frame 38 to halt it in the retracted position.
The studs 39 and 41 are each connected to protruding members 58 and
59 which may be urged together to retract the studs. The subframe
43 may be released from coplanar alignment with the rear legs 48
and 49 by squeezing the protruding members together against spring
44. The subframe 44 with the kneeler frame held in coplanar
alignment therewith by detents 53 and 54 may then be swung around
pivot pins 51 and 52 into the storage position lying just under the
seat of the chair.
Detents 61 and 62 mounted on subframe 43, as shown in FIG. 6,
engage holes 63 and 64 respectively on the chair to retain the
subframe 43, with the kneeler frame 38 held in coplanar alignment
therewith, in the storage position just underneath the seat of the
chair.
The short legs which project from the kneeler frame 38 at an angle
provide support for the frame in the down position. When the
kneeler is not in use it may be swung into coplanar alignment with
the subframe as shown in FIG. 6. The short legs are therefore
out-of-the-way and do not interfere with ordinary use of the chair
either when the kneeler frame is retracted as shown in FIG. 6, or
when the entire assembly is swung up to the storage position.
Obviously many modifications and variations of the present
invention are possible in the light of the above teachings. It is
therefore to be understood that within the scope of the appended
claims, the invention may be practiced otherwise or as specifically
described.
