[0001] The present invention relates to equipment for a user to simulate walking and running
on the spot.
[0002] Equipment of this type is normally costituted by moving belts (endless belts) and
are used in gymnasia and sports centres. They are also frequently used in the medical
field, in sports medicine centres and in centres for the rehabilitation of patients
suffering from motor disorders and injuries to the lower limbs.
[0003] Such equipment is normally motorised and is thus very expensive. In addition to this,
it often causes a certain sense of insecurity in the user, who must constantly adapt
his movements to the speed of movement of the motor-driven belt.
[0004] The present invention relates to equipment of the type specified above, characterised
in that it comprises a support structure with an inclined upper plane which can support
a user performing walking or running movements up the plane, and in that the surface
of the plane is substantially smooth so as to allow the user's feet to slide freely
whereby the movements occur without the user advancing relative to the support structure.
[0005] By virtue of this characteristic, equipment is provided which can be used effectively
and conveniently, both in terms of its functional capacity and in terms of economy,
for simulating walking and running on the spot.
[0006] Further characteristics and advantages of the invention will become apparent from
the description which follows, purely by way of non-limiting example, with reference
to the appended drawings, in which:
Figure 1 is a perspective view of equipment according to the invention, and
Figure 2 is a side elevational view showing schematically the manner of use of the
equipment of Figure 1.
[0007] In the drawings, equipment for simulating walking or running on the spot is generally
indicated 1. The equipment being dealt with may be used either as gymnastic apparatus,
for example home gymnastic apparatus, or as apparatus for the rehabilitation of patients
with motor difficulties.
[0008] The equipment 1 comprises a support structure 2 constituted by a shaped part (body)
of metal or, preferably, moulded plastics material.
[0009] The body 2 has a generally wedged shape and normally has a shell or box structure.
At the corners of its lower face 3, which is rectangular and open, the body 2 has
two pairs of feet 4, 5 which enable it to rest firmly on a support surface such as
a floor. More particularly, the feet 5 at that side of the face defining the thin
end of the wedge shape are fixed. The feet 4 on the opposite side, however, are screw
feet whose height can be varied selectively. Thus, the attitude at which the body
2 rests on the ground, and consequently the inclination of the upper side of the structure,
can be adjusted by turning the feet 4. The outer face of this upper side, indicated
6 in the drawings, defines an inclined plane and upper end or top of which is located
above the feet 4.
[0010] The face 6, the surface of which is smooth, has a generally concave profile with
the concavity facing upwardly, and has a longitudinal profile in the form of an arc
of a circle or a longitudinal profile defining an arc of a curve whose radii of curvature
vary from the top of the inclined plane towards the lower end of the plane in correspondence
with the feet 5. Different longitudinal profiles may be used according to the specific
application to walking or running.
[0011] Taken as a whole, the face 6, that is the plane 8 (Figure 2) which can be considered
as ideally connecting the top and the lower end of the face, preferably has an overall
inclination of about 20° to the surface P supporting the equipment.
[0012] The curvature of the face 6 and the attitude of the support structure 2 are normally
selected so that the portion of the face 6 adjacent the feet 5 has an inclination
opposite the general inclination of the face 6 itself. In other words, the portion
of the face 6 adjacent the feet 5 is slightly inclined towards the top region supported
by the feet 4.
[0013] The upper side of the body 2, the outer surface of which defines the face 6, is substantially
rigid, although it has a certain degree of resilient flexibility to forces exerted
thereon during use of the equipment.
[0014] Two bushes 7 are mounted in the body 2 at the upper end of the inclined face 6 and
define two vertical-axis apertures which allow a handhold or handlebar 8 to be fixed
to the body for supporting the user. The handhold 8 is constituted essentially by
a tubular metal element bent into a U shape, the straight limbs of which are slidably
engaged in the bushes 7 integral with the body 2.
[0015] The straight limbs defining the pillars of the handhold 8 are slidable vertically
in the bushes 7 and are locked in the assembled position by means of pins 9 which
engage holes 10 in the sides of the bushes 7. Each pillar of the handhold 8 is normally
provided with several holes 11 for receiving the pins 9. The locking position of the
handhold 8 in the body 2 can thus be adjusted selectively and adapted to the stature
and preference of the user.
[0016] It is also possible, of course, to use handholds 8 which, instead of being constituted
by a single rigid piece, comprise several elements which can be fixed together in
different positions depending on the requirements of the user.
[0017] The equipment according to the invention is used in the manner shown schematically
in Figure 2.
[0018] This drawing illustrates in broken outline the silhouette of a user A who, having
got onto the equipment 1, performs walking or running movements up the inclined plane
defined by the upper face 6 of the body 2, holding himself in an erect position with
the aid of the handhold 8.
[0019] The movements performed by the user do not cause him to advance relative to the structure
2 since the user's feet slide freely on the smooth surface of the face 6.
[0020] Preferably, the user wears socks, light footwear or overshoes, which facilitate the
sliding of the feet on the inclined plane defined by the face 6, while avoiding direct
contact with the surface of the plane.
[0021] Possibly, a coating layer (indicated 6a) may be applied to the face 6 to facilitate
the sliding of the user's feet or to render this more easily controllable.
[0022] The generally arcuate shape of the face 6 reproduces the approximately circular path
described by the user's feet. The lowermost portion of the face 6, which has an inclination
opposite the general inclination of the face itself, serves to brake the sliding movement
of the user's feet and acts to some extent as a rest surface, so that the user does
not have to exert excessive force with his arms to maintain his erect posture by resting
on the handhold 8. As described above, the overall inclination of the face 6 may be
varied and adjusted at will by means of the feet 4.
[0023] It should be noted that, as already described above, the handhold 8 illustrated here
is only one of the possible configurations of support elements which can be used in
the equipment of the invention.
[0024] For example, particularly during use for motor rehabilitation, it is possible to
use support elements extending in the form of handrails at the sides of the shaped
body 2 or a handhold shaped as a handlebar, the height and inclination of which may
be adjusted selectively by the user.
[0025] Finally, it must be noted that the use of support elements in the equipment according
to the invention, although preferred, is not strictly necessary. The user may in fact
provide himself with equipment constituted solely by the part or body 2 adjacent a
wall or piece of furniture and may rest on this wall or furniture during his simulation
of walking or running on'the equipment.
[0026] Naturally, the scope of the present invention also extends to embodiments which allow
equal utility to be achieved by using the same innovative concept and particularly
to embodiments in which the part or body 2, instead of being constituted by a pressed
metal or moulded plastics shell, is formed in a different manner, for example from
shaped metal elements connected together by welding.
