Description
STATE OF ART TO WHICH THE INVENTION APPLIES
[0001] The invention pertains to the field of equipment and devices
for the development and exercise of musculature or joints by force
of resistance with or without measuring devices. The invention is
classified in A63B 21/00 according to the International Patent
Classification.
TECHNICAL PROBLEM
[0002] Exercise, functional diagnostics and rehabilitation can in
principle be performed by means of two types of load, namely by
means of a free load (e.g. weight lifting or rope pulling) wherein
the load enables the movement of the extremity or the body in all
directions, or by means of a lever of the exercising
device/appliance wherein the movement of the extremity is limited
by means of a set rotational axis of the device or any other form
of leading. In exercising or diagnostics my means of moving a
lever, the extremity can move only in a way and in the direction in
which the device lever itself moves. When performing a movement
with a free load, the extremity moves along an arbitrary trajectory
of the person exercising. However, during the exercise, functional
diagnostics or rehabilitation of the extremity on the appliances
and devices on which users exercise so that their extremity causes
a semicircular movement of the appliance/device lever, or when the
appliance/device by means of a lever moves the extremity of the
user in a semicircular manner, the extremity movements on such
devices are performed in a way so that the lever which moves due to
the force of the extremity or the force produced by the device
itself is rotated around a particular axis, consisting of the
fixture point of the exercising, rehabilitation or diagnostics
appliance/device lever. The extremity mainly moves by means of a
mechanical rotation around the joint which is a fixed point of the
extremities fixture. In this case there are two axes of rotation,
one represented by the lever axis of the device and the other
represented by the axis consisting of the extremity joint which is
fixed on the lever.
[0003] However, considering that the axis around which the
extremity is rotated and the axis around which the device lever is
rotated do not necessarily, at every moment, go through the same
imaginary line in space, there is a gap during the movement of the
extremity fixed on the device lever wherein the point of connection
of the extremity and the device lever cannot disclose the same
curve in relation to these two axes of rotation. On the existing
levers of such devices, considering that the same levers are fixed
without the possibility of rotation on the point where the
extremity s attached or the impossibility that the extremity
attachment can slide parallel to the extremity, the user can suffer
extremities load due to mechanical laws stating that every point
which rotates around a certain axis will try to retain such
movement in a way so that it is equidistant from the centre of
rotation. This form of movement reduces efficiency, affects the
measurement accuracy and can lead to unnatural load and
consequently injuries.
STATE OF THE ART
[0004] Searching the state of the art, specifically searching the
PATENTOSCOPE and ESPACENET patent databases shows that levers as
parts of the exercising, training and functional diagnostics
devices, similar to this lever which is the subject of the
invention, are not subject to patent protection nor do they exist
in commercial use. Namely, it is a lever ensuring so far the most
trustworthy tracking of the extremities movements in relation to
the power, speed and moment parameters measurement and representing
a significant departure from the state of the art and the current
knowledge about the possibilities of registering the actual moment
of the extremities muscles on the registration devices, thereby
increasing the exercising efficiency and reducing the risk of
injuries.
BRIEF SUMMARY OF THE INVENTION
[0005] The present invention refers to a lever containing a slider
which solves the primary problem of ensuring a trustworthy
measurement of the extremity movement and power parameters, whether
the extremity performs isokinetic, isotonic, isometric exercises,
in a concentric or eccentric manner, or the combinations
thereof.
[0006] A secondary problem the present invention solves is taking
the pressure off the extremity joint that underwent
training/testing/diagnostics because the lever attachment adjusts
to the extremity during the entire time that the extremities moves
in a way so that it moves on a trajectory on which the extremity
also moves. In this process there is no resistance overcoming nor
is there any tension, as opposed to the situation when the
extremity moves on one trajectory and the extremity attachment on a
close, but completely different trajectory.
[0007] A lever with a slider that is installed into the extremities
exercising, rehabilitation and functional diagnosis appliances and
devices consists of: [0008] attachment onto the axle of the
appliance or the device onto which it is installed [0009] one or
more slider guides, [0010] guides limiter, [0011] a slider which is
composed of a slider carrier and a slider axle fixed onto it,
wherein there is, on the slider axle, a slider limiter and the key
of the slider axle among which there is the extremities attachment
movably positioned onto the slider axle; wherein the slider, using
a slider carrier is movably positioned on the slider guides; and
wherein the said slider lever enables the movement of the point of
contact of the extremities and the extremities attachment around
the extremities joints axis.
[0012] The key of the slider axle prevents the extremities
attachment from falling out of the slider axle, whereas the slider
limiter ensures the extremity's necessary functional distance from
the slider lever. Furthermore, the function of the key of the
slider axis is to prevent that the extremity attachment rotates
around the slider axle more than it is necessary and that, when
doing so, does not hinder the use of the same.
[0013] On one end, one or more slider guides are connected to the
appliance or device axle attachment onto which the slider lever is
fixed, whereas on the other end the slider guides are embedded into
the guides limiter in order to ensure the stiffness of the slider
guides and to prevent the falling out of the slider from the
guides. It is preferable that the guides are profiled in a way so
that only linear slider movement on the guides is enabled and that
the profile of the guides does not allow the rotation of the slider
around the guides axis.
[0014] Furthermore, it is preferable that the slider lever consists
of two guides.
[0015] The attachment to the axle can rounded, partially in form of
an arc or in any other embodiment which most closely reflects the
parallel with the extremity line as best suits the designer,
preserving thus during the process of design the functionality of
the slider lever attachment onto the axle of the device/appliance
for exercising, rehabilitation or functional diagnostics.
[0016] In an embodiment of the invention, the slider carrier can
contain one or more linear bearings that are installed along the
guides for better movement purposes.
[0017] Also, the extremities attachment may have a built-in linear
bearing so that it can slide better, that is, rotate better around
the slider axis.
[0018] Fixing the extremities into the extremities attachment can
be performed in different ways--in the preferred embodiment by
means of a "velcro" tape wherein the extremities are fixed at both
ends of the extremities attachment wherein the tape, if the
extremities are attached from the front, reinforces the extremities
from the back and vice versa. Another possible way of fixing the
extremities is by means of a system for fixing and adjusting the
length of the rope in sailing equipment, as for example Cam Matic
system developed by the company Harken.
[0019] The present invention can solve the mentioned problems in a
way so that the extremity moves around the joint as its axis,
whereas the point of contact of the extremity and the extremity
attachment of the device for rehabilitation, training and
functional diagnostics with regard to performed mobility elements
also moves around the joint axis and not around the axis onto which
the device lever is fixed. Therefore, the curves in space
describing the points of contact of the extremity and the extremity
attachment, wherein one point is on the extremity and the other one
on the extremity attachment, are identical. For this reason, the
most correct transmission of the extremity movement onto the lever
occurs and therefore also the most correct display of the measured
characteristics of the extremity musculature is created.
[0020] On the other side, the extremity joint is relieved from
pressure which is put on the joint by the lever which was firmly
fixed onto the extremity. This ensures that the device for moment
registration will register the actual moment created by the
extremity muscle.
[0021] The slider lever is mainly intended for use in highly
sophisticated devices for training, rehabilitation and functional
diagnostics, but it can also be used in other, less sophisticated,
devices when the user wishes to use the advantages of the present
invention.
[0022] Thus, the present invention can be applied to appliances and
devices for exercising, rehabilitation and functional diagnostics
such as, for example, devices of the manufacturers CON-TREX,
BIODEX, CSMI or ISOMED2000 and it specifically addresses the
problem of the extremity musculature movement transfer onto the
device in a way so that the influence on joints and skeletal system
supporting the muscles which perform the exercise (or which are the
subject of rehabilitation, that is, functional diagnostics) is
minimized.

DETAILED DESCRIPTION OF AT LEAST ONE OF THE WAYS OF INVENTION
PERFORMANCE
[0040] The invention is performed in such a way so that the axle
attachment (10), made by machine processing from the piece of a
steel plate, is permanently and suitably fixed onto the axle of the
exercising device which is also the servomotor axle. The axle
attachment (10) can be rounded, partially in form of an arc, so
that it most closely reflects the line of the lower extremities as
shown on FIG. 1, wherein the forming preserves the functionality of
the slider lever attachment (30) onto the exercising,
rehabilitation or functional diagnostics device/appliance.
[0041] Two round steel slider guides (12) of a high degree surface
processing are fixed at the lower end of the axle attachment (10)
and are also, at the lower end, firmly attached into the guides
limiter (14) which is made of steel, thereby forming a lever (30).
The slider (35) is performed by interconnecting, by means of a
detachable connection, the following steel elements produced by
machine processing, namely the slider carrier (16), slider limiter
(18), extremities attachment (20), key of the slider axle (22) and
the slider axle (24) wherein the said elements are interconnected
in such a way so that the slider carrier (16) is fixed on one side
of the slider axle (24) whereas the slider limiter (18) is fixed
right next to it, and then the extremities attachment is attached
on the axle and the same attachment slides over the slider axle and
can rotate around it, provided that the free end of the slider is
locked and fixed by means of a key of the slider axle. Once put
together, the slider (35) is then attached onto the slider guides
(12) which are fixed from the bottom by means of a guides limiter
(14) so that the slider does not fall out from the slider guides.
The slider axle (24) is then firmly and vertically fixed on the
slider carrier and the key of the slider axle (22) is installed on
the side of the slider axle which is most far apart from the slider
guide, whereas the slider limiter (18) is installed on the side
closer to the slider carrier. The slider (35) can move along the
guides from the place of connection of the guides and the axle
attachment to the place of connection of the guides and the guides
limiter. The slider carrier (16) consists of embedded linear
bearings, one for each slider guide.
[0042] The extremities attachment (20) moves along the slider axle
(24) linearly in the direction of the attachment carrier axis with
the possibility partially rotating around the attachment carrier
axis, as much as it is allowed by the key of the slider axle (22).
The extremities attachment has an embedded linear bearing for
better sliding, that is, better rotation around the attachment
carrier axis.
[0043] The fixing of the extremities into the extremities
attachment (20) is performed by means of a "VELCRO.RTM." tape
wherein the tape is fixed on the two sides of the extremity
attachment.
[0044] One of the ways of how to use the slider lever is shown in
FIG. 2. The lever with slider, shown in this case for
exercising/rehabilitation of the left knee is fixed onto the
servomotor (40) axle (50), that is, the actuator/dynamometer axle
which is a constituent part of the exercising device/appliance. It
can be fixed onto a chair on which a person is seated, that is, it
can be a separate part of the device. The left lower leg is fixed
into the extremities attachment.
[0045] In the second possible embodiment used for training
exercises of the right lower leg, the slider lever is performed as
if it was a mirror reflection in relation to the slider lever for
exercising the left lower leg.
[0046] In the third possible embodiment for pelvic muscles
exercising/rehabilitation, the slider lever which is installed on
the servomotor (40), wherein the person exercising is standing up,
is fixed on the extremity attachment from the upper side of the
upper leg.
[0047] In the fourth possible embodiment, when the person
exercising is lying face down, the extremity attachment of the
slider lever is fixed on the extremity (lower leg) in a way so that
it is, from the back of the lower leg, almost always from the side
on which the person exercising must overcome higher resistance.
[0048] In the fifth possible performance, the extremity attachment
can be fixed also laterally on the extremity depending on the group
of muscle performing the exercise.
[0049] In other embodiments, the lever with slider can be carried
out accordingly so that hand rehabilitation/exercises can be
performed, especially when it comes to persons who cannot form a
grip (for example due to loss of hands, fingers, etc.).
