OBJECT OF THE INVENTION
[0001] The present invention refers to a device which has been especially designed for carrying
out physical exercises, specifically at the level of the upper extremities of the
users, achieving rotating motions in shoulders, shoulder blades, clavicles, elbows
and wrists, mainly in rehabilitation processes, although it is also usable in prevention
exercises.
[0002] The device is especially suitable for being used in rehabilitation centers, but it
is likewise usable in gymnasiums or at the individual level.
BACKGROUND OF THE INVENTION
[0003] Certain physical problems such as tendinitis, among others, have as a consequence
a limitation of mobility at the level of certain joints, such as at the level of the
shoulder, elbow or wrist, which is necessary to recover by means of rehabilitation
exercises.
[0004] It is also known that many problems in the joints are the result of a certain muscular
weakness, specifically in the muscles surrounding a certain joint.
[0005] Consequently, both for preventing this type of problems and for the rehabilitation
once they have occurred, physical exercises are carried out in rehabilitation centers
and in gymnasiums, which obviously can also be carried out at the individual level,
i.e. in the home of each individual and with suitable instructions from a professional,
it having been proven that a plane motion provided to the hands, within an imaginary
plane and with a circumferential trajectory, is especially suitable for rehabilitation
and prevention of problems in any of the mentioned joints, i.e., shoulder, shoulder
blade, clavicle, elbow or wrist. In fact, the mobility of the upper extremities in
exercises similar to those carried out while cleaning windows is recommended as a
therapy for these cases.
[0006] Recognition is given to document
DE 3726825, comprising a training device for the strengthening of the back and the neck and
back joint, comprising a type of stretcher on which the user must lie facedowrn, said
stretcher having at its sides crooked handles the position of which can be regulated
allowing the user to perform an exercise similar to that of swimming.
[0007] While the aforementioned movement may be favourable in treating physical problems
such as the aforementioned tendonitis, said device is extremely bulky, and thus takes
up considerable space, thereby also considerably limiting its possibilities for practical
usage, and furthermore the exercise performed, specifically the type of movement,
is not the most appropriate in light of the intended aim of the invention, namely
that of treating or preventing complaints in which the movement of the arms must be
performed from a fixed position for the body with planetary movements of the hands
within a single plane, since what is achieved by the aforementioned German patent
is a movement similar to that of a crawl-type swimming stroke.
DESCRIPTION OF THE INVENTION
[0008] The device proposed by the invention fills in this technological gap, constituting
a simple and effective solution for carrying out the previously mentioned exercises.
[0009] To that end and more specifically, said device is constituted of a pair of supports
which are intended for being fixed to a wall or the like in their simplest version,
but which can form part of an autonomous apparatus in which said supports are carried
out in columns projecting from a base platform, which grants to said columns the suitable
stability, above all taking into account that the user is intended to be located thereon
while doing the exercise.
[0010] In any case, each one of these supports, vertically elongated and with the possibility
of adjustment regarding the mutual spacing thereof, is arranged with a kind of guide
for adjusting it to the body width of the user, for example based on an alignment
of likewise vertical openings, such that these openings are selectively usable for
the articulated connection of a connecting rod which, according to the selected opening
of the guide, will adopt a determined height, also according to the body size of the
user.
[0011] Each one of these connecting rods is finished off at its free end with a kind of
mitten, connected also in an articulated manner thereto, a mitten which can include
a belt in order to improve the fixing of the former to the hand of the user, a hand
which must be maintained outstretched since the efficacy of the exercise is greater
in this position.
[0012] According to another feature of the invention, it has been provided that both the
articulated connection of each connecting rod to the corresponding support, and of
the mitten to the corresponding connecting rod are carried out by means of conical
bearings which, according to a greater or lesser axial tightness, oblige a greater
or lesser effort in the rotating motion both of the connecting rods and of the mittens,
in order to intensify the exercise to be carried out or not.
[0013] The possibility that the pivot shafts of the connecting rods are finished off with
respective pinions at their rear ends, i.e. behind the supports or support columns,
has also been provided for, especially when it is an autonomous device, such that
with the help of a crank and a transmission chain, the therapist is the one providing
the motion to the upper extremities of the patient, which are fixed to the mittens
by means of corresponding belts, with the speed which the therapist considers suitable.
[0014] Each connecting rod will additionally incorporate a longitudinal alignment of openings
for the selective use in the coupling of the corresponding mitten, also for the purpose
of regulating at will the plane motion of the latter by means of a greater or smaller
spacing with regard to the pivot shaft of the connecting rod on the support, i.e.
with a greater or smaller effective length of the connecting rod.
DESCRIPTION OF THE DRAWINGS
[0015] To complement the description being made and for the purpose of helping to better
understand the features of the invention, a set of drawings is attached as an integral
part of said description, according to a preferred practical embodiment example thereof,
in which the following has been shown in an illustrative and non-limiting manner:
Figure 1 shows a front elevational view of a device for rehabilitation of upper extremity
joints, carried out according to the object of the present invention and according
to the embodiment variant thereof in which the latter is fixed to a wall.
Figure 2 shows a side elevational view of the device of the previous Figure.
Figure 3 shows a plan view of the same device.
Figure 4 finally shows a schematic perspective view of the support of the device when
it is an autonomous apparatus not requiring a wall for its fixing.
PREFERRED EMBODIMENT OF THE INVENTION
[0016] In view of the described Figures, it can be observed how the device proposed by the
invention is constituted of two vertical supports which, according to the embodiment
variant shown in Figures 1. to 3, are carried out in respective approximately Z-shaped
section profiles (1), such that by means of one of the branches thereof, the one corresponding
to reference number (1), and with the collaboration of openings (2), its fixing to
the wall is carried out by means of screwing, whereas its other branch (3) has a longitudinal
alignment of openings (4) and is markedly distant from the wall (5) for the purpose
of allowing the necessary manipulations for fixing and changing the position of the
rotating shaft (6) for a connecting rod (7), which will be described below.
[0017] However, the device can be autonomous, i.e. the wall (5) not being necessary for
the fixing of the former, in which case the supports (1) are carried out in columns
(1') extending to the floor, as is observed in Figure 4, specifically the columns
are fixed with the possibility of adjusting the spacing thereof on a platform (8),
granting the columns (1') the suitable stability, above all during the exercise, in
which the user is standing on said platform (8), loading it with his or her body weight,
these columns (1') having respective longitudinal alignments of openings (4) for the
same purpose of adjusting the height level for the connecting rods (7).
[0018] On the end opposite to the hinge pin (6) with regard to the supports (1-1'), these
connecting rods (7) incorporate in turn an alignment of openings (9) allowing for
selective coupling for the shaft (10) of respective mittens (11), preferably provided
with belts (12) for fixing of the hand which, outstretched, perfectly adapts to the
mittens (11).
[0019] Each connecting rod (7) rotates around its shaft (6) with interposition of a conical
bearing, such that according to a greater or lesser tightness of said bearing, it
is achieved that the turn of each connecting rod (7) requires a greater or lesser
physical effort, and the same occurs with the rotating shaft (10) of each mitten (11)
with regard to the corresponding connecting rod (7).
[0020] The front offset of the branch (3) of the supports (1) with regard to the wall (5)
allows for the necessary manipulations on the rear side of said branch in order to
carry out the fixing of the shafts (6), as is especially observed in Figure 3, whereas
when an autonomous support such as that in Figure 4 is used, there is no problem whatsoever
in manipulating the locking screws of the shafts (6) on the rear side of the columns
(1'), said shafts (6) in this case, as has already been stated previously, being able
to be finished off on the rear side of the support with respective pinions which,
with the collaboration of a third pinion, a chain and a crank, not shown in said Figure
4, allow the physical therapist to provide motion to said crank, and, by means of
the connecting rods (7), to the mittens (11), in order for the physical therapist
to be the one who moves the arms of the patient with the suitable speed.

height, each connecting rod (7) furthermore having, at the end opposite that which
rotates on the corresponding support (1) a further line of openings (9) for the selective
coupling of a rotating shaft (10) of a mitten (11), properly configured in order to
