FIELD OF INVENTION
The present invention relates to bed rails. More particularly the
present invention relates to a bed rail assembly which is held to
a child's bed in a manner so as to prevent dislodgement thereof.
Bed rails are typically utilized to protect children, elders, or
injured persons from falling off a bed. The current technology of
bed rails is quite basic in that most bed rails have either metal
or plastic parts which protrude from the bed rail and are placed
under the mattress and typically between the mattress and bedspring
or between the mattress and other support. Traditional bed rails
rely upon the friction between the mattress and the box spring to
keep the bedrail in place. Quite often this is insufficient to retain
the bed rail in place on the bed. It is therefore extremely advantageous
to provide a bed rail which substantially avoids if not eliminates
the danger of a bed rail slipping away from its intended position
An adjustable bed rail capable of squeezing a mattress either alone
or together with a bedspring to lock the protective side rail in
place. The locking means is adjustable to adjust for the height
of the mattress either alone or together with the bedspring. Friction
pads and/or surfaces mounted along surfaces of the bed rail engage
the mattress to further enhance the locking of the side rail to
the mattress. In one preferred embodiment the rail portion drops
down when unlocked the facilitate climbing onto or off of the bed.
The rail is adjustable in length to accommodate different bed lengths
and different occupants.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT(S)
FIG. 1 shows a bed rail assembly 10 embodying the principles of
the present invention, the upper rail portion protecting a person,
i.e., an adult or a child, from falling off the bed and is comprised
of two horizontal bars or tubes 11 and 12. Upper bar 11 is curved
at 11a and 11b to form vertically aligned portions 11c and 11d.
Tubular member 12 has its ends secured to the vertical portions
11c, 11d of member 11. If desired, additional horizontal bars may
be placed above and/or below member 12. Also, the length (i.e. "height")
of portions height 11c and 11d and the lengths of the bars 11 and
12 may be increased if desired without departing from the scope
and spirit of the present invention. Members 11 and 12 are preferably
formed of a suitable light-weight material such as tubular steel
or aluminum or a suitable plastic. If desired, the members 11 and
12 may also be formed of wood or other solid material which is preferably
light-weight and yet sturdy. Bar 11 also bends outwardly at 11e
and 11f and extends into assemblies 13 and 14 respectively.
Each of the assemblies 13 and 14 has a pair of elongated, bifurcated
arms 13a, 13b and 14a, 14b secured to the lower ends thereof. In
addition thereto, each of the assemblies 13 and 14 has a movable,
lockable end 16 17 which is vertically aligned, each receiving
one of the vertical arms 16a, 17a. These lockable arms 16a and 17a
may be hollow or solid.
FIG. 2 is an enlarged view of the mattress holding portion of the
bedrail of FIG. 1. FIG. 3 is a sectional view of FIG. 2 looking
in the direction of arrows 3--3 and FIG. 4 is partially sectionized
view of the structure of FIG. 2 looking in the directions of arrows
4--4 and further showing brackets B1 pivotally mounting locking
arm 15 by means of a pivot pin P, only one assembly being described
for purposes of simplicity. Hollow tubular member 16 has an opening
16b for receiving a projection 15a of the locking arm 15. As locking
arm 15 is moved to dotted line position 15', the forward tip 15b
of projection 15a moves away from opening 16b, enabling the arm
16a to be moved relative to tubular portion 16 to adjust to the
height of a mattress M.
The arm 16a is positioned relative to tubular member 16 preferably
so as to "squeeze" mattress M between the horizontal member
13c and bifurcated arms 13a, 13b. When the mattress M is adequately
"squeezed," locking arm 15 is moved to the dotted line
position 15''. In this position, projection 15a enters into opening
16b and tip 15b of projection 15a thereof presses against an adjacent
side of arm 16a. The tip 15b assumes an over-center position relative
to center line CL. This over-center position is retained by the
lower edge of the locking arm 15 to lock the arm 16a within hollow
tubular member 16.
The assembly 14 operates in a substantially identical manner.
In order to further enhance the holding force applied to the mattress
by the bed rail assembly 10 friction pads (not shown) may be placed
on the underside 13d, 14d of horizontal members 13c, 14c and/or
on the upper surface of arms 13a, 13b and 14a, 14b.
FIGS. 5 11 show a presently preferred embodiment 20 of the present
invention which is comprised of a rail portion 22 and a supporting
portion 24. The rail portion 22 is generally comprised of a pair
of side posts 25 26 and upper and lower cross pieces 27 and 28
coupled to the side posts at each corner thereof.
The supporting portion 24 is comprised of a pair of base members
33 and 34 which are substantially identical in design and function
to one another and only one of these base members will be described
herein for purposes of simplicity. The base member 33 has a portion
33a at its inner end extending into a hollow L-shaped bracket 35.
Fastening member 36 extends therethrough to hold base member 33
pivotably in place. The opposite end 33b of base member 33 is of
increased width and has an upper surface 33c provided with a V-shaped
or sawtooth configuration to facilitate providing a firm grip upon
The free-end of base member 33 is tapered as shown at 33d to facilitate
sliding of the base member beneath a mattress and typically between
a mattress and a boxspring. A rugged, flexible fabric or plastic
web 37 extends through an elongated slot 33e provided in the end
having a sloping surface 33d. Web 37 is provided with a locking
element 64 for snap-fitting within a cooperating locking element
65 coupled to one end of a web 62 the opposite end of which is
coupled to a preferably flat plate 63 which may be placed against
a sidewall of the mattress opposite the sidewall along which the
rail is mounted to provide additional means for holding the side
rail in place. Alternatively, as is shown in FIG. 11 a Y shaped
web 70 may be coupled at one end to base members 33 34 and at the
apex 70a to a web 71 provided with a locking member 64' similar
to locking member 64. A web 72 is threaded through plate 63' at
an end and is coupled to a locking member 65' similar to locking
member 65 for releasably locking with locking member 64.
L-shaped bracket 35 (and its mirror image 55) is hollow and has
a substantially rectangular-shaped cross-section. The upper end
35a telescopingly receives an elongated arm 38 whose upper end extends
into a hollow opening a second L-shaped bracket 39 the upper end
of member 38 being provided with an opening (not shown) that cooperates
with openings on opposite sides of member 39 for receiving fastener
40 to secure members 38 and 39 to one another.
Member 38 (and its mirror image 58) is also preferably hollow (as
shown in FIG. 9), and has a rectangular-shaped cross-section similar
to that of the upper end 35a of L-shaped bracket 35. Member 38 is
slideable within bracket 35. One side surface of member 38 is provided
with a plurality of step openings 38a. Bracket 35 is provided with
a spring loaded locking knob 41 in which an internal bias spring
(not shown) normally causes the locking knob 41 to be urged inwardly
into bracket 35 in the direction shown by arrow A. Although not
shown, the opposite end of locking knob 41 is provided with a tip
that mates with and engages an associated one of the openings 38a.
By lifting or lowering member 38 one of the openings 38a may be
selected to be aligned with the locking knob 41 which is normally
pulled out to permit the member 38 to freely slide with bracket
35. When the member 38 reaches the desired position, locking knob
41 is released, causing its tip to enter one of the openings 38a
and thereby lock the supporting structure in a selected position.
The arm portion 39a of L-shaped bracket 39 (and its mirror image
59), is provided with openings on opposite sides thereof which cooperate
with openings on opposite sides of a projecting portion 30a of corner
bracket 30. The fastening member 42 extends through the openings
in projecting portion 30a as well as through the opposite sidewalls
of bracket portion 39a of L-shaped bracket 39 to pivotally couple
these members together.
The projecting portion 30a has a locking/release button 44 shown
in FIGS. 6 9 and 10. When the rail portion 22 is in the upright
position as shown in FIGS. 5 and 7 a locking button 50 that is
spring loaded by internal spring bias means 51 (both shown in FIGS.
9 and 10) locks arms 39a and 30a in the upright position by engaging
hole 52 in arm 30a. In order to facilitate climbing onto and off
of the bed, buttons 44 (on both supporting portions) are pressed
in to remove button 50 from the opening 52 in corner bracket 30
to enable rail portion 22 to freely pivot about pivot pin 42 enabling
the rail portion to pivot in the counterclockwise direction shown
by arrow C in FIG. 5 so as to move the rail portion to a downward
position whereby the sides 25 and 26 are substantially aligned with
the slideable members 38. In this lowered position, the button 44
which is biased downward by an internal bias spring 45 engaged
an angled holding hole 47 that holds the rail in the lowered position.
The button 44 can be released from this holding hole 47 allowing
the rail portion to be raised by pivoting the rail assembly about
pivot members 42. When the rail assembly reaches the upright position,
the locking button 50 automatically locks into position through
hole 52 by pressing the button 44 back through hole 52. As can be
understood, the force exerted by spring 51 attached to the button
50 is greater than that exerted by spring 45 attached to button
As is best shown in FIG. 5 a lightweight and yet rugged netting
61 is placed across the opening in the rail frame formed by members
25 26 27 and 28. The netting 61 may be provided with upper and
lower sleeves 61a, 61b which receive the upper and lower crosspieces
27 and 28 the netting being placed upon members 27 and 28 before
assembly of the rail portion.
The netting 61 is also provided with side sleeves 61c, 61d for
slideably receiving the side frames 25 and 26. The netting may also
be provided with a storage pocket 61e, open at its upper end and
having a stretchable edge 61f for storage, for example, of bed clothing
or any other items which a user may desire to place in the pocket.
The upper and lower members 27 and 28 are preferably comprised
of a pair of tubular members 27 27a and 28 28a. Members 27 and
28 telescope int members 27a, 28a to adjust the length of the frame.
If desired, the frame members 25 26 may be similar in design to
adjust the height of the rail.
The bed rail is mounted to a bed by placing the base members 33
and 34 beneath a mattress and moving the base members further beneath
the mattress until the upright portions of L-shaped brackets 35
and 55 are either in engagement with or nearly in engagement with
an adjacent sidewall of the mattress. Each of the locking buttons
such as locking button 41 is released, enabling each of the slideable
members such as slideable member 38 to be moved downwardly until
the mattress is firmly gripped between the undersurface of bracket
portion 39a and the base member 33. The locking member 41 is released
whereby the pin-shaped free end of the locking member enters one
of the openings 38a to hold the assembly in the desired position
preferably at least slightly squeezing the mattress between the
undersurface of arm 39a and base member 33.
FIG. 7 shows a view of the underside of arm 39a of L-shaped bracket
39 as being provided with a pad 57 having a saw-tooth like pattern
of V-shaped grooves, further cooperating with base member 33 and
the V-shaped grooves, provided there-along to firmly grip the mattress
In the event that further holding forces are desired, the fastener
64 coupled to the free end of web 37 may be snapped-fitted into
a cooperating locking member 65 coupled to one end of the second
elongated web 62 whose opposite end is coupled to an elongated plate
63 which may be positioned to engage a sidewall of the mattress
M on the opposite side of the mattress from that along which the
rail is mounted. The lower end of member 63 engages a sidewall of
a box spring (not shown) thereby holding the bed rail assembly in
place. Either web 37 or web 62 or both, are adjustable to adjust
the distance between L-shaped bracket 35 engaging one side-wall
of the mattress and member 63 engaging the opposite side wall of
the mattress. Base member 34 may be provided with a similar structure.
