Description
[0001] This invention relates to exercise apparatus and, more
especially, this invention relates to apparatus for exercising a
person's legs.
[0002] There are many different types of known apparatus for
exercising a person's legs. A first known type of apparatus is free
standing in the form of a bar, stands for each end of the bar, and
loose weights for placing on the bar. A second type of known
apparatus is in the form of a floor mounted machine. Both of these
first and second types of apparatus are usually best suited for use
in a gym. If they are used in a home, they tend to be too bulky
and/or too heavy for easy storage when not in use. A third type of
known apparatus attempts to meet these problems of the apparatus
being too bulky and/or too heavy for easy storage when not in use.
However this third type of known apparatus does not function
effectively and/or is of complicated manufacture.
[0003] It is an aim of the present invention to avoid or reduce the
above mentioned problems.
[0004] Accordingly, in one non-limiting embodiment of the present
invention there is provided apparatus for exercising a person's
legs, which apparatus comprises: [0005] (i) a platform on which the
person stands in use of the apparatus; [0006] (ii) a bar for
extending across the person's upper body such that the person is
able to exercise their legs by performing a leg exercise; [0007]
(iii) at least one length of stretchable material which in use
extends upwardly from the platform; [0008] (iv) first and second
lengths of non-stretchable material which in use extend downwardly
from the bar; [0009] (v) first connecting means for connecting the
length of stretchable material to the first and second lengths of
non-stretchable material; and [0010] (vi) first and second
length-adjusting means for respectively adjusting the first and
second lengths of non-stretchable material such that the length of
stretchable material gives a desired resistance when the person is
performing the leg exercise and is moving from a first position to
a second position, with the second position being higher than the
first position, and wherein: [0011] (vii) the length of stretchable
material has first and second end portions and a central portion
between the first and second end portions; [0012] (viii) the
platform comprises at least one first aperture for the first end
portion of the length of stretchable material, and at least one
second aperture for the second end portion of the length of
stretchable material; [0013] (ix) there is a first roller formation
which is on an underside of the platform and which is adjacent the
first aperture for facilitating movement of the length of
stretchable material relative to the platform; [0014] (x) there is
a second roller formation which is on the underside of the platform
and which is adjacent the second aperture for facilitating movement
of the length of stretchable material relative to the platform;
[0015] (xi) in use the central portion of the length of stretchable
material passes underneath the platform, the first and second end
portions of the length of stretchable material respectively extend
upwardly through the first and second apertures in the platform and
away from the platform, and the person is positioned over the
central portion and between the first and second end portions of
the length of stretchable material; [0016] (xii) the first and
second lengths of non-stretchable material are spaced apart such
that in use the person is positioned between the first and second
lengths of non-stretchable material; [0017] (xiii) the bar
comprises first position-securing means for the first length of
non-stretchable material; [0018] (xiv) the bar comprises second
position-securing means for the second length of non-stretchable
material; and [0019] (xv) in use the first and second
position-securing means respectively secure the first and second
lengths of non-stretchable material to the bar such that from a
front view: [0020] (a) the first position-securing means is
vertically above the first aperture in the platform, whereby the
first length of non-stretchable material and the first end portion
of the length of stretchable material extend in a straight vertical
line between the first aperture in the platform and the first
position-securing means; and [0021] (b) the second
position-securing means is vertically above the second aperture in
the platform, whereby the second length of the non-stretchable
material and the second end portion of the length of stretchable
material extend in a straight vertical line between the second
aperture in the platform and the second position-securing
means.
[0022] The apparatus of the present invention is ideally suited for
home use. More specifically, the apparatus is easy to use. Also,
the apparatus is able to be produced to be much lighter than known
apparatus, and this facilitates storage and movement of the
apparatus in the home. Furthermore, the light weight of the
apparatus facilitates the sale of the apparatus by mail order. The
first and second lengths of non-stretchable material are able to be
adjusted in length by the first and second length adjusting means.
This enables a person using the apparatus to be in the first
position, for example in a squat position, with zero resistance
from the length of stretchable material. This in turn enables the
person to position the bar comfortably across their upper body
prior to moving from the first position to the second position and
thereby encountering the desired resistance from the length of
stretchable material.
[0023] Advantageously, the desired resistance from the length of
stretchable material is equally transferred to the first and second
lengths of non-stretchable material extending downwardly from the
bar. This equal apportionment of the resistance from the length of
stretchable material to the first and second lengths of
non-stretchable material remains constant even if the length of
stretchable material stretches with use and thus provides a varying
resistance. If a first length of stretchable material were to be
provided for the first length of non-stretchable material, and a
second and separate length of stretchable material were to be
provided for the second length of non-stretchable material, then
any wear occurring on the two lengths of stretchable material could
be unequal. This could provide different resistances through the
first and second lengths of non-stretchable material to the bar,
where the different resistances would be felt by the person using
the apparatus and which could adversely affect their concentration
or other use of the apparatus.
[0024] Also advantageously, if a person is in the first position,
for example in a squat position, and the person is unable to move
to the second position, for example an erect position, the person
is easily able to hold the bar in their hands and move out from
underneath the bar. This is because, in the first position, the
length of the stretchable material is at its weakest strength. This
provides a safety feature for the person, and compares favourably
with many known types of apparatus where there is maximum load at
the first position, making it difficult to move out from underneath
the bar and/or requiring one or two extra persons in attendance for
the purpose of helping to lift the bar if the person performing the
exercise cannot rise from the first position.
[0025] The apparatus may be one in which the first and second
position-securing means are loop formations which are connected to
the bar, and in which the first and second lengths of
non-stretchable material are configured to pass respectively
through the first and second position-securing means.
Alternatively, if desired, the first and second lengths of the
non-stretchable material may be provided with fastener means, for
example clips to fasten to the first and second position-securing
means.
[0026] The apparatus may be one in which there is a plurality of
the lengths of stretchable material, in which there is a plurality
of the first apertures in the platform, in which there is a
plurality of the second apertures in the platform, and in which
there is at least one of the lengths of stretchable material for
extending through opposite pairs of the first and second apertures
in the platform. Increasing the number of lengths of stretchable
material employed increases the resistance felt by the person when
performing the leg exercise. For example, the apparatus may be one
in which there are three of the first apertures in the platform,
and three of the second apertures in the platform. Two or more than
three of the first apertures and two or more than three of the
second apertures may be employed if desired. Each aperture may be
of such a size that it is able to receive the relevant parts of two
or more, for example three, of the lengths of stretchable
material.
[0027] The apparatus may be one in which the bar is a solid bar of
circular cross section, or it may be one in which the bar is a
hollow tube of circular cross section. The bar will usually be a
straight bar but it may be of a non-straight configuration if
desired. The bar may be made of a metal or a plastics material. The
plastics material may be, for example, polypropylene.
[0028] The apparatus may be one in which the first connecting means
comprises a clip connecting means. The clip connecting means may be
a quick release clip connecting means having an openable portion
which is biased to a closed position. Other types of first
connecting means may be employed.
[0029] The apparatus may be one in which the length of the
stretchable material has the clip connecting means, and in which
the length of the non-stretchable material has ring members which
receive the clip connecting means. Other configurations may be
employed so that, for example, the reverse arrangement may be
employed in which the clip connecting means is on the length of the
non-stretchable material, and the ring members are on the length of
the stretchable material. Connecting members other than ring
members may be employed.
[0030] The length-adjusting means may be a clamp device through
which the length of non-stretchable material passes. The clamp
device may employ a clamping cam. The clamping cam may be part of a
clamping lever. The length adjusting means may be the type of
device which is employed for seatbelts in cars and aircraft. Any
suitable and appropriate type of length-adjusting means may be
employed.
[0031] The length of non-stretchable material may be a strap. The
strap will typically be of a thin flat construction. The length of
the non-stretchable material may alternatively be in the form of a
cord or a cable.
[0032] The length of stretchable material may be a length of an
elastic material. The length of stretchable material, for example
the length of the elastic material, may be rectangular in cross
section. Alternatively, the length of the stretchable material may
be a tube. The tube may be solid or rigid. Typically, the tube will
be of a circular cross section.
[0033] Advantageously, the apparatus is such that the platform, the
bar, the length of the stretchable material, and the length of the
non-stretchable material are separable from each other. This
facilitates selling of the apparatus by mail order. It also
facilitates storage of the apparatus at home. Alternatively, one or
more of the component parts of the apparatus may be permanently
secured together.
[0034] The platform member may be of any suitable and appropriate
construction. The platform member may thus be made of a plastics
material which enables the platform member to be light for ease of
handling. When the platform member is made of a plastics material,
then the platform member may be moulded to the required shape. The
underneath of the platform member may be provided with
strengthening ribs.
[0035] The apparatus of the present invention is advantageously
such that it enables the person to do various leg exercises. The
main leg exercise would be a back squat, with the bar extending
across the person's shoulders. If desired however the person may
conduct a leg exercise in the form of a front squat with the bar
extending across the person's upper chest. For leg exercises in the
form of back squats or front squats, the desired resistance from
the length of the stretchable material will usually be obtained by
adjusting the length of the non-stretchable material with the
person in the squat position. If an alternative leg exercise were
to be required, for example calf raises for exercising the person's
calves, then the resistance required of the length of the
stretchable material would typically be that required for a rear
squat or a front squat when the person is in an upright
position.
[0036] Embodiments of invention will now be described solely by way

[0055] FIG. 19 shows a length of stretchable material; and
[0056] FIG. 20 is an enlarged view of one end portion of the length
of stretchable material shown in FIG. 19.
[0057] Referring to FIGS. 1-4, there is shown apparatus 2 for use
by a person 4 for exercising their legs 6. The apparatus 2
comprises a platform 8 on which the person 4 stands in use of the
apparatus 2. The apparatus 2 also comprises a bar 10 for extending
across the person's upper body 12 such that the person 4 is able to
exercise their legs 6 by performing a leg exercise.
[0058] The apparatus 2 comprises at least one length of stretchable
material 14 which in use extends upwardly from the platform 8. The
apparatus 2 also comprises first and second lengths of
non-stretchable material 16 which in use extend downwardly from the
bar 10. First connecting means 18 is provided for connecting the
length of stretchable material 14 to the first and second lengths
of non-stretchable material 16.
[0059] The apparatus 2 further comprises first and second
length-adjusting means 20 for respectively adjusting the first and
second lengths of non-stretchable material 16 such the length of
stretchable material 14 gives a desired resistance when the person
4 is performing the leg exercise and is moving from a first
position as shown in FIG. 1 to a second position as shown in FIG.
2. As can be appreciated from a comparison of FIGS. 1 and 2, the
second position is higher than the first position.
[0060] The apparatus 2 is such that there is one length of the
stretchable material 14. The length of the stretchable material 14
has a first end portion 22, a second end portion 24, and a central
portion 26 which is between the first end portion 22 and the second
end portion 24. The central portion 26 passes underneath the
platform 8. In use, the first and second end portions 22, 24 extend
upwardly away from the platform 8. In use, the person 4 is
positioned over the central portion 26 and between the first and
second end portions 22, 24.
[0061] As shown in FIGS. 1 and 2, the two lengths of
non-stretchable material 16 are spaced apart. In use, the person 4
is positioned between the two lengths of the non-stretchable
material 16.
[0062] The two lengths of the non-stretchable material 16 slideably
extend transversely over the bar 10. Each of the two lengths of
non-stretchable material 16 has one of the length-adjusting means
20 for enabling the adjustment of the length of the non-stretchable
material 16.
[0063] The bar 10 includes first and second position-securing means
30, 32 respectively. The two lengths of the non-stretchable
material 16 pass one through each of the first and second
position-securing means 30, 32. The first and second
position-securing means 30, 32 are loop formations which are
connected to the bar 10.
[0064] The bar 12 may be a solid rod of circular cross section, or
it may be a hollow tube of circular cross section. A hollow tube
may be preferred in cases where it is desired to keep the weight of
the apparatus 2 to a minimum.
[0065] The various component parts of the apparatus 2 may be made
from any suitable and appropriate materials. Thus, for example, the
lengths of stretchable material 4 may typically be made of a rubber
material. The lengths of the non-stretchable material 16 may
typically be a webbing material. The platform 8 may be made of
wood, a plastics material or a metal. The bar 10 may be made of a
metal. The first connecting means 18 will typically be made of a
metal.
[0066] FIG. 4 is a top view of the platform 8 and shows how the
platform 8 is provided with two sets of three apertures 34. The
apertures 34 in use are opposite pairs of first and second
apertures 34. FIG. 5 is an underneath view of the platform 8 and
shows the apertures 34. The length of stretchable material 14 is
shown passing underneath the platform 8 and through the central
aperture 34 in the two sets of apertures 34. FIG. 6 is a side view
of the platform 4 as shown in FIGS. 4 and 5. It will be seen from
the side view that the platform 8 is formed of a top portion 36 and
spaced apart bottom portions 38, 40. The spacing of the bottom
portions 38, 40 creates a space 42 in which the length of
stretchable material 14 can run. In FIG. 6, the length of
stretchable material 14 has not been shown.
[0067] In use the first and second position-securing means 30, 32
respectively secure the first and second lengths of non-stretchable
material 16 to the bar such that from a front view, the first
position-securing means 30 is vertically above the first aperture
in the platform 8, whereby the first length of non-stretchable
material 16 and the first end portion of the length of stretchable
material 14 extend in a straight vertical line between the first
aperture in the platform 8 and the first position-securing means
30. Also in use the second position-securing means 32 is vertically
above the second aperture in the platform 8, whereby the second
length of the non-stretchable material 16 and the second end
portion of the length of stretchable material 14 extend in a
straight vertical line between the second aperture in the platform
8 and the second position-securing means 32.
[0068] As can be appreciated from FIGS. 5 and 6, the length of
stretchable material 14 passes over roller formations 44 on either
side of the platform 8. The roller formations 4 facilitate movement
of the length of stretchable material 14 relative to the platform
8.
[0069] FIGS. 4 and 5 show that there are three of the apertures 34
in each set. More or less than three of the apertures 34 can be
provided. The apertures 34 can be of varying shapes. Each aperture
34 may receive one, two or more lengths of the stretchable material
14. Also, lengths of the stretchable material 14 in different ones
of the apertures 34 can be used together. Generally, increasing the
number of lengths of stretchable material 14 that are used will
increase resistance and will require more effort from the person 4
when performing an exercise.
[0070] Referring to FIG. 7, there is shown a top view of the
platform 8 but with apertures 46 which are of a different shape to
the apertures 34. More specifically, the apertures 34 are closed
apertures through which the lengths of stretchable material 14 are
threaded. The apertures 46 are open apertures with entrance slots
47 for receiving the lengths of stretchable material 14, and this
facilitates the sideways locating of the lengths of stretchable
material 14 in their apertures 46.
[0071] FIG. 8 is a top view of the platform 8 but with apertures 48
which are of a different shape to the apertures 34 and the
apertures 46. The apertures 48 are in the form of open slots for
receiving longitudinal edges of the length of flexible material 14
in the same manner as the entrance slots 47 of the apertures 46.
The use of entrance formations may facilitate the location of
relatively thick lengths of stretchable material 14 in the
apertures 46, 48.
[0072] FIGS. 9, 10 and 11 show the bar 10 with the first and second
position-securing means 30, 32. The position-securing means 30, 32
are shown as being open rectangular formations which extend from a
top part of the bar 10 when the apparatus is in use. The
position-securing 30, 32 have ends 63 which are able to be inserted
into apertures (not shown) in the bar 10. The apertures may be
drilled or otherwise provided in the bar 10.
[0073] In alternative embodiments of the invention, the first and
second position-securing means 30, 32 may be replaced by other
position-securing formations including position-securing formations
which extend from the periphery of the bar 10, and
position-securing formations in the form of recesses which extend
into the bar 10. The position-securing means, for example the first
and second position-securing means 30, 32, may advantageously help
to keep the lengths of non-stretchable material 16 and their
attached lengths of stretchable material 14 in line and correctly
positioned with respect to the platform 8. The position-securing
means 30, 32 may also advantageously act to stop the lengths of
non-stretchable material 16 from sliding off the ends of the bar
10.
[0074] FIGS. 12, 13 and 14 show the length of non-stretchable
material 16. FIG. 12 shows the length of non-stretchable material
16 in a rolled non-use position. FIG. 13 shows the length of
non-stretchable material in a use position, and with one end
portion 64 passing through the length adjusting means 20. FIG. 13
also shows the length of non-stretchable material 16 being provided
with a ring connector 66 which forms part of the first connecting
means 18. FIG. 14 shows the ring connector 66.
[0075] FIG. 15-18 are various view of a preferred length-adjusting
means 20. It will be seen that the length-adjusting means 20 is of
a general lever and cam operated construction of the type employed
in seat belts for aircraft. Thus the length-adjusting means 20
comprises a body 70 and a lever 72. The lever 72 pivots about a
pivot 74 relative to the body. The lever 72 comprises a cam portion
76 which operates against a formation 78 to lock the length of
stretchable material 16 in position.
[0076] FIG. 19 shows the length of stretchable material 14 as used
in the apparatus 2. The length of stretchable material 14 is shown
in FIGS. 19 and 20 as being provided with first connecting means 18
at each of its end portions 22, 24. The first connecting means 18
is a clip connecting means. The clip connecting means 18 is a
quick-release clip connecting means 18 having a body 80 and an
openable portion 82. The openable portion 82 is biased to the
closed position shown in FIGS. 19 and 20.
[0077] It is to be appreciated that the embodiments of the
invention described above with reference to the accompanying
drawings have been given by way of example only and that
modifications may be effected. Thus, for example, other types of
first connecting means 18 may be employed. Other types of lengths
of stretchable material 14 and non-stretchable material 16 may also
be employed. The apparatus 2 is shown with the person 4 forming a
back squat. The person 4 may alternatively perform a leg exercise
in the form of a front squat by placing the bar 10 across the upper
part of their chest. The person 4 may alternatively perform a leg
exercise in the form of a calf exercise by standing in the position
shown in FIG. 2 and then repeatedly raising on their toes and then
lowering back down again. Individual components shown in the
drawings are not limited to use in their drawings and they may be
used in other drawings and in all aspects of the invention. The
invention also extends to the individual components mentioned
and/or shown above, taken singly or in any combination.
