Description
[0001] The present invention relates to an exercise device for at
least parts of the back musculature of the human body, including a
back-rest against which the user can rest at least part of his back
during the exercise.
[0002] An exercise device of the aforementioned type is known from
the German laid-open specification DE 40 03 537 A1. In the exercise
device described therein, the back-rest is immediately above the
seat area and, in an area a little way above the seat area, has a
portion that extends convexly forward. Above this convex portion
there is a bar against which the upper part of the user's back can
be rested. This bar can be moved backward against the weight of a
number of weight elements. On top of the thigh and in front of the
lower leg there is an L-shaped holding element which can hold the
user's pelvis in place in the space between the seat area and the
convex portion of the back-rest. When the user's upper back moves
backward against the weight, the spine is strengthened in the
lumbar area. The disadvantage of this is that the holding of the
pelvis in place prevents active straightening of the user's pelvis.
As a result there can, in particular, be no segmental movement in
the kyphosis of the lumbar spine, which is considered important for
the treatment of backpain patients.
[0003] The object of the present invention is to create an exercise
device of the kind mentioned at the start which can be used more
effectively in the treatment of backpain patients.
[0004] According to the invention, this is achieved by an exercise
device of the kind mentioned at the start with the characterizing
features of claim 1 or of claim 16 or of claim 18 or of claim 21.
The subordinate claims relate to preferred embodiments of the
invention.
[0005] Claim 1 provides that the exercise device also has operating
elements which the user can hold during the exercise, wherein the
user can move or hold the operating elements against a restoring
force in such a way that pelvic straightening and/or pelvic tilting
of the user is effected at least in part against the restoring
force. In the exercise device according to the invention, unlike in
the described prior art, the pelvis is not held in place, but can
rather be straightened and/or tilted against the restoring force,
allowing exercise of the pelvic musculature and the postural
musculature (multifidus muscle) of the lumbar spine. Backpain
patients can be treated effectively in this manner. This involves,
in particular, the activation of the multifidus muscle and the
transverse muscle, which should be activated in co-contraction.
[0006] It is possible for the operating elements to be designed
and/or arranged in the exercise device in such a way that the
restoring force can operate in the direction of the arms of the
user outstretched forward at shoulder or hip level. During the
exercise the user can hold the operating elements in a front
horizontal position, which generates considerable innervation of
the extensor muscles of the back, in particular the postural
musculature in the vicinity of the areas moved, i.e. in the
vicinity of the motion segments of the lumbar spine.
[0007] It may be provided that the exercise device includes at
least one pulling element which has one of the operating elements
at its user end. A pulling element can transfer the restoring force
by simple means.
[0008] It is also possible for the exercise device to include at
least one weight element whose weight can produce the restoring
force. As an alternative or in addition, it is possible for the
exercise device to include electromotor, hydraulic, or pneumatic
restoring elements which can produce the restoring force. The at
least one pulling element may be connected to the at least one
weight element and/or to the restoring elements. Such arrangements
have proved their worth in exercise devices.
[0009] As an alternative or in addition, it is possible for the at
least one pulling element to be an elastic pulling element against
whose elastic restoring force the operating elements can be moved.
In such an embodiment, the provision of one or more weight elements
and/or of electromotor, hydraulic, or pneumatic restoring elements
may be dispensed with if need be. It is possible, for example, to
provide a number of elastic bands of differing strengths, which may
be selected according to the strength of the restoring force
required.
[0010] It is also possible for the exercise device to include
movement-limiting elements which can limit the movement of the
pelvis of the user during the exercise. By this limiting of the
movement of the pelvis, particularly during straightening of the
pelvis, it is possible to ensure that in backpain patients exercise
to strengthen the muscles is carried out gradually and without
risk.
[0011] The movement-limiting elements can be arranged behind the
lumbar spine of the user during the exercise. The movement-limiting
elements can, for example, be arranged at the level of the third or
fourth lumbar vertebra and in this way limit the amplitude of the
movement of the lumbar spine.
[0012] It may be provided that the movement-limiting elements are
arranged between the seat area and the back-rest.
[0013] In particular, it is possible for the height of the
movement-limiting elements and/or their distance from the lumbar
spine area of the user to be able to be adjusted. This
adjustability allows the exercise device to be adapted to different
users.
[0014] It may also be provided that the exercise device includes
measuring elements which can register the movement of the lumbar
spine. The exercise device can include display elements which can
show movements registered by the measuring elements. The movement
of the lumbar spine of the user can be monitored very well in this
way. The integration of a display unit allows kinesthetic
perception of the exercise sequences. The user thus gets continuous
feedback on the current position of the spine.
[0015] It is also possible for the seat area to slant forward, in
particular at an angle of between 5.degree. and 20.degree.,
preferably at an angle of about 10.degree., to the horizontal. Such
a seat position takes the weight off the lumbar area, allowing more
effective exercise of the postural musculature of the lumbar
spine.
[0016] It is also possible for the exercise device to include a
foot-rest which, in particular, is height-adjustable.
[0017] In claim 16, it is provided that the exercise device
includes measuring elements which can register pelvic straightening
and/or pelvic tilting of the user.
[0018] In claim 18, it is provided that the exercise device
includes movement-limiting elements which can limit the amplitude
of a movement of the lumbar spine area of the user.
[0019] In the case of the embodiments in claim 16 and claim 18, it
is also possible to place the exercise device near an exercise
station that allows cables to be pulled out against a restoring
force. Here, too, the pelvis can be straightened and/or tilted
against such a restoring force.
[0020] In the embodiment in claim 21, it is provided that the user
performs pelvic straightening in a standing position. Thanks to the
measuring elements, the user gets continuous feedback on the
current position of the spine, allowing particularly effective
exercise.
[0021] Other features and advantages of the present invention are
made clear with the aid of the following description of preferred
embodiments, reference being made to the enclosed figures, in
which
[0022] FIG. 1 shows a lateral view of a first embodiment of an
exercise device according to the invention, including a user, whose
lumbar spine is in a first position;
[0023] FIG. 2 shows a view which corresponds to that in FIG. 1, but
in which the lumbar spine of the user is in a second position;
[0024] FIG. 3 shows a perspective view of a second embodiment of an
exercise device according to the invention;
[0025] FIG. 4 shows another perspective view of the embodiment of
the exercise device shown in FIG. 3;
[0026] FIG. 5 shows a perspective view of a detail of the
embodiment of the exercise device shown in FIG. 3;
[0027] FIG. 6 shows a sectional view of the detail shown in FIG.
5.
[0028] It can be seen from FIG. 1 and FIG. 2 that the depicted
embodiment of an exercise device according to the invention
includes a base plate 1, attached to which are a seat unit 2, a
holding unit 3, and a weight tower 4.
[0029] The weight tower 4 includes, in the usual manner, a number
of weight elements (not shown) whose weight, individually or in
combination, can operate as a restoring force. The weight tower 4
has a pulling unit 5 which allows the weight elements to be raised
by means of two cables that serve as pulling elements 6. At the
user ends of the cables there are handles which respectively serve
as operating elements 7. The pulling unit 5 also includes guide
pulleys 8 which are height-adjustably mounted on the weight tower 4
such that the height of the cable ends which can be held by the
schematically depicted user 9 can be adjusted. It is thus perfectly
possible to move the guide pulleys 8 upward such that the user 9
can hold the handles at shoulder level. Preferably, however, the
guide pulleys 8 may be moved to a height that allows the operating
elements 7 to be held by the user at the hip level of the user.
[0030] It is possible for there to be mounts (not shown) starting
at the guide pulleys 8 and extending in the direction of the user.
These make it easier for the user to get hold of the operating
elements 7. One of these mounts can be formed in such a manner that
it can be swung up or down out of the way to make it easier for the
user to get into the exercise position.
[0031] The holding unit 3 includes a horizontally adjustable and
lockable pad 10 which serves as a holding element. This pad 10 can
sit against the front of the lower leg and/or of the knee of the
user during the exercise. There is a height-adjustable foot-rest 11
which is mounted either on the holding unit 3 or on the seat unit
2.
[0032] The seat unit 2 includes a seat area 12 which slants forward
at an angle of about 10.degree. to the horizontal. The seat unit 2
also includes a height-adjustable back-rest 13 against which the
upper part of the back of the user 9 rests during the exercise. The
seat area 12 and the back-rest 13 are connected to each other by a
support element 14. In an alternative embodiment, the back-rest 13
is not height-adjustable.
[0033] The seat unit 2 also includes measuring elements which can
register the movement of the lumbar spine. These measuring elements
include a vertically and horizontally adjustable pad 15 which can
be placed against the lumbar spine area 16 of the user 9. The pad
15 is mounted on a pivotable carrying element 17. The carrying
element 17 is mounted on the support element 14 such that it can
pivot about a pin 18. Since the pad 15 lies against the lumbar
spine area 16, the movement of the pelvis of the user 9 from the
first position (FIG. 1), in which the pelvis is straight upright,
to the second position (FIG. 2), in which the pelvis is tilted,
thus causes the carrying element 17 to pivot backward, i.e.
leftward in FIG. 2. This movement of the carrying element 17 is
registered by a sensor 19, which is part of the measuring elements,
is attached to the support element 14, and is connected to the
carrying element 17 by means of a cable 20.
[0034] The movement of the lumbar spine 16 of the user 9 registered
by the measuring elements, i.e. the sensor 19, can be shown by
display elements 21 which are attached to the weight tower 4. By
means of these display elements 21, it is also possible, for
example, to present the user 9 with a movement--in the form of a
spot that moves over the screen or suchlike--which he should as far
as possible imitate with his lumbar spine area 16. It is also
perfectly possible for the display elements to be formed as a
mechanical display. For example, an arrow-shaped display element
may be moved over a scale by a cable which may be directly
connected to the sensor 19 or to the carrying element 17.
[0035] It is also possible for the pad 15 to serve as a
movement-limiting element. The pivoting movement of the carrying
element 17 can be prevented for this purpose, for example. If the
pad 15 is then locked in place at a preselectable distance from the
lumbar spine area 16 of the user 9 in the first position of the
pelvis, the pelvis, during tilting, can only be moved as far as the
point at which the lumbar spine area 16 is in contact with the pad
15.
[0036] For this, the pad can be arranged at the user end of a rod
22 which can be moved within a casing 23. The rod 22 can be locked
in place in the casing 23 by means of a turning knob 24. A scale 25
enabling the therapist for example to set the starting position for
the exercise can be provided on the top of the casing 23.
[0037] In the embodiment of an exercise device in FIG. 3 to FIG. 6,
parts that are the same as in FIG. 1 and FIG. 2 are given the same
reference numbers.
[0038] Extending upward from a base plate 1 is a vertical bearer
26. The vertical bearer 26, on its side which faces the middle of
the base plate 1, has two elongate pads 27 and 28, which extend
vertically over a considerable distance, e.g. about a meter. The
pads 27, 28 are some distance apart from each other transversally.
During an exercise in a standing position, a user can rest parts of
his back, in particular parts of the upper back, and also the
buttocks against the pads 27, 28. The pads 27, 28 thus serve both
as a back-rest and as rests for part of the user's buttocks.
[0039] The embodiment in FIG. 3 to FIG. 6 likewise includes
measuring elements which can register the movement of the lumbar
spine. These measuring elements likewise include a vertically and
horizontally adjustable pad 15 which can be placed against the
lumbar spine area of the user (not shown in FIG. 3 to FIG. 6). The
pad 15 is part of a movement-registering unit 29, which is shown in
detail in FIG. 5 and FIG. 6.
[0040] It can be seen from FIG. 6 in particular that the pad 15 is
mounted on a horizontal rod 30 which can be moved in the direction
of the arrow 31. The movement-registering unit 29 also includes a
sliding carriage 32 which can be moved on a rail 33 in a casing 34
in the direction of the arrow 35. The rod 30 can be locked in
position in the sliding carriage 32 by means of a locking element
36 which can engage with the sliding carriage 32 via a slotted hole
37 in the casing 34. The sliding carriage 32 is connected to a
cable 38.
[0041] Since the pad 15 lies against the lumbar spine area, the
movement of the pelvis of the user, e.g. from the first position,
in which the pelvis is straight upright, to the second position, in
which the pelvis is tilted, thus causes the rod 30 and hence the
sliding carriage 32 to move leftward in FIG. 6. This movement of
the sliding carriage 32 is transferred to the cable 38.
[0042] The movement-registering unit 29 also includes a vertical
rod 39 which is vertically adjustable in a casing 40 that is
connected in a stationary manner to the vertical bearer 26. For
this, a locking element 41 which can engage with openings 42 formed
in the vertical rod 39 is provided on the casing 40, for example.
The casing 40 is arranged on the vertical bearer 26 in such a way
that the rod 30 carrying the pad 15 projects between the two
elongate pads 27, 28 toward the user. The top of the rod 39 is
attached to the casing 34.
[0043] The exercise device in FIG. 3 to FIG. 6 also includes a
display column 43 with display elements 44. The cable 38 ends in
these display elements 44. For example, an arrow-shaped display
element may be moved over a scale by the cable 38. The cable 38 may
be connected to a spring, e.g. attached to a torsion spring (not
shown), in the display elements 44 such that the sliding carriage
32 can be moved leftward in FIG. 6 against the force of the spring.
The effect of this is that, after a movement of the lumbar spine
area of the user toward the right in FIG. 6, the sliding carriage
32 and thus the pad 15 is automatically moved back toward the
right.
[0044] The integration of the display elements 44 allows
kinesthetic perception of the exercise sequences. The user thus
gets continuous feedback on the current position of the spine.
[0045] In the embodiment in FIG. 3 to FIG. 6 too it is possible to
have a sensor that is connected to display elements formed as a
screen for example.
[0046] In the area of the vertical bearer 26 there may be a
dumb-bell rack. From this the user can take dumb-bells, which he
can hold during the exercise with the result that straightening
and/or tilting of the pelvis can be effected at least in part
against the weight of the dumb-bells.
[0047] It is also possible for the display column 43 to have
attached to it one or two elastic pulling elements the ends of
which can be held by means of suitable operating elements for
example. Straightening and/or tilting of the pelvis can then be
effected against the elastic restoring force of the pulling element
or elements.
[0048] It is also possible for there to be a weight tower 4 as in
the first embodiment shown in FIG. 1 and FIG. 2 instead of or in
addition to the display column 43. This allows users exercising in
a standing position to pull the cables out against the restoring
force of the weight elements of the weight tower 4. The pelvis can
thus be straightened and/or tilted against such a restoring force
when exercising in a standing position also.
[0049] Alternatively, it is possible for the embodiment of the
exercise device in FIG. 3 to FIG. 6 to be placed near an exercise
station that allows cables to be pulled out against a restoring
force. Here, too, the pelvis can be straightened and/or tilted
against such a restoring force.
[0050] It is also possible for the embodiment of an exercise device
in FIG. 1 and FIG. 2 to be provided with a movement-registering
unit 29 as per FIG. 5 and FIG. 6. The weight tower 4 can then also
be provided with mechanical display elements 44, for example.
