Treadle assembly of an exercise equipment
Abstract
A treadle assembly of an exercise equipment including treadles
each with a pair of connection ears for pivotally attaching the
treadles to corresponding treadle planks of the exercise equipment.
A soft elastic element is fitted at the front and rear sides
between the treadles and the treadle planks, respectively.
Accordingly, the treadles are subject to an angle change with the
force acting on the treadles due to the effect of the soft elastic
elements.

Claims
1. A treadle assembly of an exercise equipment, comprising
treadles, the treadles each having a pair of connection ears for
pivotally attaching the treadles to corresponding treadle planks of
the exercise equipment, a soft elastic element being fitted at the
front and rear sides between the treadles and the treadle planks,
respectively, so that the treadles is subject to an angle change
with the force acting on the treadles due to the effect of the soft
elastic elements.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Fields of the Invention
[0002] 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.
[0003] 2. Description of the Related Art
[0004] 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.
[0005] 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
[0006] 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.
[0007] In order to achieve the above-mentioned object, a soft
filling material like rubber with ductile, compressional and
resilient elasticity is employed for producing a proper synchronic
deformation of the treadle by application of force to the treadle,
thereby resulting in proper angle change in adjustment of the soles
of the operator's feet. Of course, the filling material brings the
treadle in original position when the external force is removed. In
this way, the ankle joints of the operator can be properly
protected from injuries.
BRIEF DESCRIPTION OF THE DRAWINGS
[0008] The accomplishment of this and other objects of the
invention will become apparent from the following description and
its accompanying drawings of which:
[0009] FIG. 1 is a schematic drawing of a preferred embodiment of
the invention; and
[0010] FIG. 2 is a cutaway view of the preferred embodiment of FIG.
2.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0011] First of all, referring to FIGS. 1 and 2, each of the
treadles 10 includes a pair of connection ears 12 for pivotally
attaching the treadles 10 to corresponding treadle planks 22 of the
exercise equipment 20. A soft elastic element 30 is fitted at the
front and rear sides between the treadles 10 and the treadle planks
22, respectively. The treadles 10 are subject to an angle change
with the force acting on the treadles 10 due to the effect of the
soft elastic elements.
[0012] Based on the assembly of the above-mentioned components, as
shown in FIG. 2, the treadles 10 can swivel on the pivot of the
connection ears 12. Thus, the treadles 10 undergoes a proper angle
change with the up and down movement of the treadle plank 22 of the
exercise equipment 20 in adjustment to the soles of both feet of
the operator for protecting his ankle joints from injuries.
[0013] 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.
