Stabilized ironing table
Abstract
An apparatus is provided for stabilizing an ironing table,
comprising a weight and a hollow base member that holds the weight.
The base member connects to the legs of an ironing table and
extends outwardly from the legs. The weight in the base member adds
mass to the lower portion of the ironing table, increasing the
table's resistance to tipping or wobbling. In one aspect of the
invention, the weight may be removed from the base member to
decrease the overall weight of the ironing table when the table is
being transported.

Description
FIELD OF THE INVENTION
[0001] The present invention relates to ironing tables and more
specifically to ironing tables with stabilizing components that
reduce the potential for tipping.
BACKGROUND
[0002] In the present state of the art, ordinary ironing tables
feature an ironing surface or board that is elevated above the
floor by two or more legs. The legs are supported by base members
or outriggers that extend outwardly from the legs to balance the
table in a standing position. In this standing position, the board
is elevated to allow an individual to iron clothing, linens and the
like while the person is standing. The elevated board also prevents
clothing and linens from contacting the floor when they are being
ironed. Common ironing tables feature a light weight design to
allow the table to be easily repositioned, transported and
stored.
[0003] The light weight construction of ironing boards frequently
makes them top heavy and creates problems with table stability and
safety. Much of the table's weight is concentrated at the top of
the table when the table is in a standing position. Top heaviness
is even more apparent when an iron, clothing, and other objects are
placed on the board, adding weight to the top of the table. Under
such weight, the table's stability is limited by the configuration
of the legs. In particular, the board is typically limited in width
to approximately 15 inches, and the legs do not extend far beyond
the perimeter of the board. Therefore, the weight of the board and
its contents are balanced over a relatively small area. This
arrangement makes the table very prone to tipping and rocking so
that the table can be easily knocked over through inadvertent
contact. If a hot iron is positioned on the table, tipping over the
ironing table can lead to serious burns and other injuries.
SUMMARY OF THE INVENTION
[0004] In light of the foregoing, the present invention provides a
more stable ironing table that offers the same utility and
advantages of ordinary light weight ironing tables. The invention
features a top board supported on a pair of legs. Base members or
outriggers extend outwardly from the legs. The density of the base
members is greater than the density of the legs. One way to
increase the density of the legs is by weights. When the table is
set up for use, the weights are inserted into cavities in the base
members to increase table stability and reduce the potential for
tipping or wobbling.
DESCRIPTION OF THE DRAWINGS
[0005] The foregoing summary as well as the following description
will be better understood when read in conjunction with the figures
in which:
[0006] FIG. 1 is a perspective view of a stabilized ironing table
in accordance with the present invention; and
[0007] FIG. 2 is an exploded perspective view of a stabilizer used
in the ironing table in FIG. 1.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0008] Referring to FIGS. 1-2 in general, and to FIG. 1
specifically, a stabilized ironing table 10 is shown. Table 10
includes a generally horizontal board 20 and a pair of legs 30 that
extend from the board. Legs 30 are pivotally connected with a pin
32. The pin connection 32 allows adjustment of the table between a
standing position, in which the legs extend outwardly from board
210 to elevate the board above a floor, and a folded position, in
which the legs collapse inwardly to allow the table to be stored.
Table 10 uses a conventional latch release mechanism to adjust the
table between the standing position and folded position. In FIG. 1,
table 10 is shown in a standing position. A plurality of base
members 40 extend from the lower end of legs 30. When table 10 is
placed in a standing position, base members 40 concentrate the
table's weight in the lower portion of the table to enhance
stability and counteract top heaviness in the table. Base members
40 can have a variety of geometric configurations. In FIG. 1, base
members 40 are illustrated as a pair of straight tubular members
having a cylindrical cross section. Base members 40 are bisected by
the lower ends of legs 30 and are connected to the legs by any
connecting means known in the art. In FIG. 1, the base members 40
and legs 30 are connected by welding. Base members 40 extend along
the floor in a direction generally perpendicular to the
longitudinal axis of the board.
[0009] The legs 30 comprise the vertical support for the table. The
legs are formed of a material that is sufficient to support the
weight of the ironing board 20 and the forces applied during
ironing. However, preferably the legs are as light as reasonably
possible to limit the weight of the table 10. Accordingly,
preferably the legs 30 are formed of hollow rigid tubing, such as
steel tube having approximately {fraction (1/16)}" thick walls.
[0010] As described above, the base members 40 comprise the lateral
supports for the table 10. The base members 40 are designed to
engage the floor surface when the table 10 is set up for use. In
contrast to the vertical support legs 30, preferably the base
members 40 are designed to have a relatively high density to lower
the center of gravity of the table 10, thereby increasing the
stability of the table. More specifically, preferably the base
members 40 have a greater density than the vertical legs 30.
[0011] The increased density of the base members 40 can be
accomplished in one of several ways. For instance, the base members
40 can be formed of steel tube having a thicker wall than the tube
used to form the vertical legs, or the base members can be formed
of solid metal. However, preferably, the base members 40 are formed
of steel tube that is substantially similar to the steel tube used
to form the legs. The density of the base members is then increased
by inserting weights 50 into the base members. Specifically, as
shown in FIG. 2, preferably the base members 40 are hollow forming
a cylindrical cavity 42, and the weights are configured to
cooperate with the interior cavities of the base members. More
specifically, preferably, the mass of each weight is greater then
the mass of the corresponding base member.
[0012] Base members 40 include open ends 44 adapted to receive
weights 50. Each open end 44 is covered by an end cap 46 that
retains the weight 50 within the respective base member 40 when the
base member is tilted or moved. End caps 46 are formed with
interior recesses 47 adapted to conform with the outer perimeters
of base members 40. The interior diameter of each recess 47 is
equal to or slightly larger than the exterior diameter of each base
member 40, such that the end cap forms an interference fit when
slipped over the end of the base member. Alternatively, end caps 46
include male threads in recesses 47 that cooperate with female
threads on the ends of base members 40. Where a threaded connection
is used, the end caps connect to base members 40 when the caps are
aligned with the ends of the base members and rotated. End caps 46
are preferably formed of a flexible material, such as synthetic
rubber, or a durable plastic. The end caps may be removably
connectable so that the weight can be removed as desired, such as
to lighten the ironing board to store it. However, preferably, the
end caps 46 are substantially permanently attached to the base
member.
[0013] The addition of weights 50 to the base of ironing table 10
will affect the balance of the table. If a significant amount of
weight is placed on one side of the base with respect to the
table's longitudinal axis, the table will resist tipping in only
one direction. Preferably, weights 50 are inserted in base members
40 in an arrangement that is substantially symmetric about the
longitudinal axis of table 10.
[0014] Operation of the ironing table 10 will now be described. The
table 10 is initially stored in the folded position. Using the
latch release mechanism, table 10 is opened so that legs 30 extend
outwardly from board 20. Once the legs 30 are fully extended, base
members 40 are positioned on a floor and the table is set in the
standing position. If weights 50 are not yet inserted into base
members 40, an end cap 46 is removed from each base member to
expose the interior cavities 42 in the base members. A weight 50 is
then aligned with each cavity 42, as shown in FIG. 2, and fully
inserted into the base member 40. End caps 46 are realigned with
the ends of base members 40 and secured back onto the base members.
Ironing table 10 is now stabilized and ready for use.
[0015] With weights 50 inserted into base members 40, the center of
gravity of the table 10 is moved downwardly so that the table is
more resistant to tipping or rocking. In particular, a greater
lateral force must act on table 10 to lift the ends of base members
40 off the floor. If the end caps 46 are removable, when the user
is finished ironing, the user can remove an end cap 46 from each
base member and remove the weights 50 from cavities 42. The end
caps 46 are then reattached to the base members 40. The latch
release mechanism is actuated to return table 10 to the folded
position so the table can be conveniently transported and stored.
Weights 50 may be left in or removed from base members 40 as
desired by the user.
[0016] The terms and expressions which have been employed are used
as terms of description and not of limitation. There is no
intention in the use of such terms and expressions of excluding any
equivalents of the features shown and described or portions
thereof. It is recognized, however, that various modifications are
possible within the scope and spirit of the invention. Accordingly,
the invention incorporates variations that fall within the scope of
the following claims.
