BACKGROUND OF THE INVENTION
1. Fields of the Invention
[0001] The invention relates to a treadle assembly of an exercise equipment, and more particularly
to a treadle assembly that undergoes a proper angle change with the up and down movement
of the treadle plank of the exercise equipment in adjustment to the soles of both
feet of the operator for protecting his ankle joints from injuries.
2. Description of the Related Art
[0002] The soles of the feet of the operators are subject to a certain angle change with
the up and down movement of the treadle plank of the exercise equipment when an operator
takes exercise on a treadmill or an elliptical cross trainer. For example, the soles
of the feet tend to be raised while they rise, and they tend to be downwardly inclined
when they sink.
[0003] It's never seen that any means for adjusting the change of the treading angle is
fitted to the treadle of the conventional exercise equipment. Therefore, the operator
has to be forced to adjust himself to the angle change of the treadle. When the operator
only uses the exercise equipment for a short time, the aforementioned design may not
pose an injury risk to the operator. However, the ankle joints of the long-term operator
would be subjected to exercise injuries due to the mechanic compulsory force caused
by the unnatural positions for a long time. Most of the operators who do not realized
the potential hazard would get unknown injuries in the area of the ankle joints in
the future. If it's true, the manufacturers of the exercise equipment must be responsible
for it.
SUMMARY OF THE INVENTION
[0004] Therefore, it is a primary object of the invention to provide a treadle assembly
of an exercise equipment that protects the ankle joints of the long-term users from
potential injuries, thereby achieving more safety in operation.
[0005] By use of flexible material like rubber with ductility, compressibility und resilience,
the treadle can be simultaneously deformed according to the applied force. Therefore,
the treadle can adjust to the change of sole's angle during the whole exercise session.
When the external force is removed, the treadle can be restored to its original position
by use of a flexible connecting element. In this way, the ankle joints of the operator
can be sufficiently protected from injuries.
BRIEF DESCRIPTION OF THE DRAWINGS
[0006]
FIG. 1 is a schematic drawing of a preferred embodiment of the present invention;
FIG. 2 is a partial sectional view of another preferred embodiment of the present
invention; and
FIG. 3 is a schematic drawing of a further preferred embodiment of the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0007] The accomplishment of this and other objects of the invention will become apparent
from the following description and its accompanying drawings of which:
[0008] Referring to FIG. 1, a preferred embodiment in accordance with the invention is applied
to an elliptical cross trainer 10. It's apparent from FIG. 1 that a flexible connecting
element 20 is employed to connect a treadle 12 to a treadle plank 14 of an elliptical
cross trainer 10. In this way, a swinging and reciprocating motion can be imparted
to the treadle 12 according to the force applied by the operator. Meanwhile, the ankle
joints can be sufficiently protected from injuries by use of the flexible connecting
element 20.
[0009] Referring to FIGS. 2 and 3, other preferred embodiments of the invention are shown.
According to FIGS. 2 and 3, two or more flexible connecting elements 20 are employed
to connect the treadle 12 to the treadle plank 14 of a respective exercise apparatus
(not shown) for achieving the same expected effect. Meanwhile, the use of fixing elements
30 permits a tight attachment of the flexible connecting element 20 to the treadle
12 and the treadle plank 14.
[0010] Many changes and modifications in the above-described embodiment of the invention
can, of course, be carried out without departing from the scope thereof. Accordingly,
to promote the progress in science and the useful arts, the invention is disclosed
and is intended to be limited only by the scope of the appended claims.
1. A deflectable treadle of an exercise apparatus, comprising at least one flexible connecting
element (20) for attaching the treadle (12) to a treadle plank (14) of the exercise
apparatus.
2. A deflectable treadle according to claim 1 with two or more flexible connecting elements
(20) being employed to connect the treadle (12) to the treadle plank (14).
3. A deflectable treadle according to claim 1 or 2 with fixing elements (30) permiting
a tight attachment of the flexible connecting element (20) to the treadle (12) and
the treadle plank (14).
