Abstract
An adjustable, stowable, ballet bar exercise device, comprising: a free-standing frame carrying at least one ballet bar, and one or more rigid members coupled to the frame and lying on the floor in use.
Description




FIELD OF THE INVENTION




This invention relates to an adjustable-height ballet bar exercise device.




BACKGROUND OF THE INVENTION




Conventional ballet bars are permanently mounted to walls. They are thus limited to use around the perimeter of a room. This inefficient space utilization in commercial exercise rooms limits the size of classes, and so the income generated by the classes. For a home user, this limits the selection of rooms in which the device can be used, and also takes up valuable wall space.




Another drawback of conventional ballet bars is that they are mounted at a fixed height from the floor. However, the correct position of the bar is a function of the height of the user, a reality that is not addressed by conventional ballet bars.




SUMMARY OF THE INVENTION




It is therefore an object of this invention to provide a ballet bar that is portable.




It is a further object of this invention to provide a ballet bar of adjustable height.




It is a further object of this invention to provide a ballet bar exercise device that can carry either one or two bars.




It is a further object of this invention to provide such a device that allows the user to push down on the ballet bar as well as push up on the ballet bar in use.




It is a further object of this invention to provide such a device that can be used by either one or two people at the same time.




It is a further object of this invention to provide such a device that can be mounted to a wall.




It is a further object of this invention to provide such a device that accomplishes a greater density of users, thus increasing efficiency and income in commercial exercise classes.




It is a further object of this invention to provide such a device that is stable in use by either one or two people, but can be stowed in a small amount of space, for example in a closet or under a bed.




It is a further object of this invention to provide such a device that folds up into a relatively compact, flat package that can be easily carried and stowed away.




This invention features an adjustable, stowable, ballet bar exercise device, comprising: a free-standing frame carrying at least one ballet bar; and at least one mat member coupled to the frame. The frame may comprise at least two substantially vertical frame members. In the preferred embodiment, each of the vertical frame members comprises a collapsing construction (e.g., a telescoping device) of adjustable height. The collapsing construction may comprise a locking feature for releasably holding the ballet bar or bars at a plurality of heights.




The frame may further comprise at least two legs. At least one leg is preferably pivotably coupled to each substantially vertical frame member. There are preferably two legs pivoting on each vertical frame member. The frame may carry two ballet bars. The two bars may be coupled together in a ballet bar member. The ballet bar member is preferably pivotably coupled to the remainder of the frame.




Each mat member may comprise one mat, or two or more mats that lie on the floor in use, and are foldable one upon the other. The device may further comprise a substantially vertical backrest member coupled to the frame. The mat members preferably overlie the rigid planar members, and can each be folded up against the backrest into a stowed position.




In a more specific preferred embodiment, the invention features an adjustable, stowable, ballet bar exercise device, comprising: a free-standing frame carrying at least one ballet bar, wherein the frame comprises at least two substantially vertical frame members, each comprising a collapsing device of adjustable height, wherein each collapsing device comprises a locking feature for releasably holding at a plurality of heights, and wherein the frame further comprises at least two legs that are pivotably coupled to each vertical frame member; at least one ballet bar carried by the frame; a substantially vertical backrest member coupled to, or detachable from the frame; and at least one rigid member coupled to the backrest member or the frame, and which can be rotated to a horizontal position on the floor. Further included is at least one mat member, wherein each mat member comprises at least one mat that lies on the floor in use, and wherein each mat overlies a rigid member, so that it can be folded up against the backrest into a stowed position.




This invention also features a method of using an adjustable, stowable, ballet bar exercise device, comprising a free-standing frame carrying at least one ballet bar, and at least one rigid, planar member coupled to the frame and adapted to be placed on the floor proximate the frame, the method comprising a user placing at least a portion of the user's body on a rigid member, to apply a downward force on the rigid member and thus stabilize the frame, and the user placing another body portion on a ballet bar, to exercise by use of the device, wherein the user's body weight helps maintain the frame in position, to accomplish a free-standing ballet bar.

. Device


10


includes free-standing frame


8


comprising substantially vertical frame members


12


and


14


that are coupled to ballet bar construction


16


. Construction


16


in this embodiment comprises two ballet bars,


22


and


24


. However, this invention contemplates a device with only a single ballet bar as well. Construction


16


is designed to pivot about an axis defined by pivot pins


30




a


, as is more fully described below. Device


10


is made to be stable and free standing using pivoting leg members


40


-


43


. Leg members


40


and


41


pivot on vertical frame member


12


, and leg members


42


and


43


pivot on vertical frame member


14


. The leg members preferably include adjustable-height feet


44


, and a rubber, non-skid backing surface (not shown).




Ballet bar construction


16


is made so that the height of bars


22


and


24


are adjustable. This is preferably accomplished with adjustable-height members accomplished in any convenient mechanical means, such as collapsing with a sliding or telescoping action. In this embodiment, the collapsing action is accomplished with telescoping frame members


13


and


15


. Connecting bar


26


and connecting bar


28


join ballet bars


22


and


24


to telescoping frame members


13


and


15


. In this embodiment, the telescoping is accomplished by having telescoping members


13


and


15


that slide within vertical members


12


and


14


, respectively, and may be releasably locked in a number of height positions by any convenient mechanical means as would be apparent to those skilled in mechanical arts. Shown are friction knobs


34


and


36


that hold telescoping frame member


15


at a height indicated by scale


32


. This allows the ballet bar or bars to be collectively or individually set at a height that is comfortable for the user or users, while also allowing the device to be folded and stowed as described below. Individual height adjustment can be accomplished, for example, with two pairs of spaced telescoping members that slide within the vertical frame members, and each carry one bar.




The lower construction of frame


8


is shown in more detail in FIG.


3


. Vertical frame member


14


defines an opening that accepts telescoping frame member


15


. Knobs


34


and


36


are attached to stems, not visible in the drawing, that are tightened against the adjustable-height frame member to hold it tightly in place at the desired height, so that the bars are set at a comfortable height for the users. Channel


17


holds one edge of vertical planar member (a.k.a. backrest member)


52


, FIG.


4


. Pivoting legs


42


and


43


are shown in the deployed position that stabilizes the device so that it doesn't tip when weight is applied to the bars. These legs pivot on pivot pins that are held within vertical frame member


14


, not visible in the drawing, so that they can be folded up against the folded planar member and mat construction for storage, as further explained below. Caster wheels


48


and


49


allow the device to be wheeled in the stowed position so that it is easier to move into a storage closet or under a bed, for example. When deployed, adjustable-height feet


44


rest on the floor, and casters


49


and


48


are held off the floor.




In addition to frame


8


, device


10


comprises assembly


50


,

FIG. 4

, of rigid planar members


52


,


54


and


56


(e.g., plywood). Vertical rigid (backrest) member


52


is fixed to vertical frame members


12


and


14


. Vertical rigid (backrest) member


52


rigidly locks vertical frame members


12


and


14


in vertical alignment. In the use position shown in

FIG. 1

, one user would stand, sit or lie on one or both of mats


76


and


78


(

FIG. 5

) while using ballet bar


22


or


24


, while the other user would stand, sit or lie on one or both of mats


80


and


82


while using the other bar. Rigid planar members


54


and


56


located under mats


76


and


80


, respectively, are affixed to backrest member


52


. Since backrest member


52


is coupled to frame


8


of device


10


, the user's weight and applied force maintains device


10


in position during use. Also, when the user's weight is on one or more of the rigid planar members


54


,


56


, the user can push up against one of the ballet bars


22


,


24


, and not dislodge the bar or device from position. Thus, the rigid planar members


54


,


56


sitting on the floor and coupled to the frame


8


of the device allow the device to be used for exercises that apply force down, up or to the side of one or both ballet bars


22


,


24


. The mats sit on or are affixed to these rigid planar members


54


,


56


. The addition of an anti-skid surface to the bottom side of the rigid planar members


54


,


56


keeps the unit from slipping laterally.




Mat assembly


70


,

FIG. 5

, includes central mats


72


and


74


that are placed over backrest member


52


, FIG.


4


. Mat


76


and


78


extend to one side, and mats


80


and


82


to the other side. Preferably, these mats are hingedly connected together with living hinges or fabric hinges, for example, so that they can be folded together for storage, as explained below.




The device of

FIGS. 1-4

can be folded into a relatively flat structure for storage, as follows: Ballet bar construction


16


is designed to pivot on a horizontal axis passing through pivot points


30




a


,

FIG. 2

, so that it can be rotated to a vertical position in which bars


22


and


24


are one above the other. Ballet bar construction


16


can then be pushed down, causing telescoping frame members


13


and


15


to move down within vertical frame members


12


and


14


, respectively, to decrease the overall height of the device. The mats are arranged to allow a folding or pivoting action between them as follows. Mat


78


can be folded up and onto mat


76


. Similarly, mat


82


can be folded onto mat


80


. Rigid planar members


54


and


56


fold up to a vertical position containing the mats. The device in this stowed position thus presents a relatively flat package having a width about the width of vertical frame members


12


and


14


, and a height substantially less than shown in FIG.


1


. The device can carry wheels, preferably on the bottom of each of vertical frame members


12


and


14


, and preferably retractable and deployable so that, when the device is in use, the wheels do not touch the floor, and when the device is in the stowed position, the wheels can be moved out from their retracted position so that the device can be rolled. Alternatively, the stowed device can be carried by one of bars


22


or


24


.




The invention can be accomplished with alternative frame designs, as long as the device is portable, and carries one or more ballet bars of adjustable height. For example, the side frame members need not be vertical, or more than two supporting members could be used. Also, the bar or bars do not need to pivot relative to the frame. Also, the ballet bars do not have to rotate in order to be vertically adjustable.




Another embodiment of the invention comprising a wall-mounted ballet bar which is adjustable in height and removable for storage, is shown in FIG.


6


. Two vertically spaced holes are drilled in each of wall studs


112


and


114


, and an anchor assembly is inserted into each hole. Removable vertical bars


92


and


94


are placed over anchor assemblies


98


and


99


, and


100


and


101


, respectively. These vertical bars have a number of spaced holes so that ballet bar


110


can be held at a desired height. Mounting brackets


104


and


102


engage with bars


94


and


92


, respectively, and hold ballet bar


110


. Thus, the ballet bar and the vertical bars are easily removed from the wall when not in use.
