Description

Introduction

The invention is made for people with drip feet, where a strong pull is required for the calf muscle to be stretched.

The invention thus relates to a training apparatus for extending a rigid calf muscle, as stated in the preamble of claim 1.

The prior art

It is known to perform manual training of, for example, leg muscles, for example by extension, and descriptions of apparatus for use in the extension of, for example, leg muscles are found in the patent literature.

Known clamping devices for use in drop feet are made with a handle, as shown in WO 2005/089140 A2 and US 6,206,807 B1.

In principle, the construction known from US 6,206,807 B1 can achieve a partial extent. However, it requires hard and uncontrolled extension, for example, there does not appear to be the necessary stability in the form of support from the tibia and down to the foot, and because the entire construction of this known apparatus is built up so that the extension must take place by hand . Not because there is anything wrong with using hand power, but experience shows that an enormous amount of energy is needed to just have a small effect when it comes to stretching the calf muscle. Furthermore, when considering how strong an unstimulated calf muscle can be and how frequently the calf muscle needs to be stretched (4-5 times daily), it will be clear that the method alone by hand will not suffice.

In addition, the apparatus described in WO 2005/089140 A2 will be too complicated to use when lying down or otherwise unable to use the arms. In addition, a strain that will relax the calf muscle will be so demanding that you would not be able to maintain the stretch needed to get the necessary effect. Thus, a force of between approx. 98.07 N - 980.7 N (10 kg-100 kg) or alternatively a force of between approx. 98.07 N - 686.5 N (10 kg-70 kg).

In addition, there is known ffa US 2013/0040782 All a training apparatus for exercising muscle groups on the back of a person's leg to an extent, the training apparatus comprising a frame and a footplate, the footplate being pivotally attached to a bearing, positioned relative to the person's foot.

SUMMARY OF THE INVENTION It is an object of the invention to provide an apparatus which improves the known manual drip foot tensioning apparatus when hand force is not sufficient to obtain the necessary training.

This and other objects are achieved with the invention, as will be explained in more detail below.

The invention relates to

The invention, as set forth in claim 1, relates to a training apparatus for extending a rigid calf muscle, the training apparatus comprising a bottom plate rotatable relative to a pivot point. The invention is characterized in that the training apparatus further comprises - a vertical rail with a fastening at the top, and wherein the vertical rail and the base plate are rotatable relative to each other via said pivot point, - a fastening outermost on the base plate, - an electric motor mounted between the fastening at the top of the vertical rail and the fastening at the outermost of the base plate, where, upon activation, the electric motor will move the base plate about the pivot point, and where, at a given voltage, the electric motor exerts a force between the fastening at the top of the vertical rail and the fastening at the bottom of the pivot point. as well as - setting options for the electric motor migration in the form of a wattmeter, which should act as both safety and stop.

In the invention, with the electric motor, at a given voltage, a force will be exerted which can be, for example, between approx. 98.07 N - 2942 N (10 kg-300 kg). There must be set options for the electric motor migration in the form of a wattmeter, which should both act as safety and stop. The wattmeter is a safety measure and indicator for people who are not able to sense when the pressure is getting too great.

The clamping device is characterized by the use of an electric motor rather than hand power. In addition, the device maintains the tension in the calf muscle.

In the invention, a maximum drag in the foot is ensured by the electric motor, so that during the entire stretch of the calf muscle, the necessary pull will be provided until the desired effect of the stretch is achieved.

According to a convenient embodiment, as claimed in claim 2, whereby the apparatus is made more user-friendly, the electric motor can also be mounted on the rear of the vertical rail, so that the training apparatus / drip foot machine will be easier to get in and out of, since the attachment at the top of the vertical rail will not turn forward. The motor tension on the base plate will be relatively close to the pivot point. The base plate will be longer, ie. extend backwards and the vertical rail will not stop at the back of the base plate, but will be a distance inside the base plate. This will result in a greater exchange of the engine, since no much traveling is required to do the same work.

According to a further convenient embodiment, as claimed in claim 3, there may be two locking mechanisms for the foot. There should be one over the foot and one around the tibia. The locking mechanism around the foot must counteract the force applied through the electric motor so that the foot is held in the correct position during the entire stretch. This is done by attaching the locking mechanism close to the pivot point of the base plate, where the vertical rail meets the horizontal base plate. This is done to have the most support on the foot as a pressure is placed on the electric motor which will force the foot to lift. A locking mechanism is also mounted around the tibia. The locking mechanism must be mounted far down on the vertical rail in order for the leg and foot to be in the correct position during the stretching.

According to yet another suitable embodiment, as claimed in claim 4, the length of the vertical rail can be designed in 3 sizes (small, medium and large). The length of the vertical rail must be the correct height to get the desired power. Nonetheless, a pull / pressure is applied at the top of the vertical rail, so that the most stretch will be achieved if the top of the rail is as close to the kneecap as possible. It can, for example, be designed in 3 sizes, small, medium and large.

According to yet another convenient embodiment, as claimed in claim 5, there may be a support surface throughout the foot so that not only is pulled under the toes as, for example, the existing prior art as described in WO 2005/089140 A2.

According to a further convenient embodiment, as claimed in claim 6, the training apparatus may be made of hard plastic and carbon fiber.

According to a further convenient embodiment, as claimed in claim 7, the base plate may comprise a mechanical foot plate for adjusting the desired movement.

With such a mechanical footplate you can adjust how high the base plate, or rather the mechanical footplate that sits above the base plate can be raised. This is only necessary if the desired hike is not sufficient. Alternatively, wedges have been used to increase the migration to obtain the desired effect, ie. wedges located above the base plate.

It should be noted that when placing the electric motor at the rear of the vertical rail, the additional mechanical base plate will not be needed as an adjustment option, since the motor's stress on the foot plate will be relatively close to the pivot point. As mentioned above, this will result in a greater exchange of the engine.

According to yet another convenient embodiment, as claimed in claim 8, the training apparatus may be designed to exert a force via the electric motor that is - within a range between about 10 and about 50 degrees. 98.07 N - 2942 N (10 kg - 300 kg), - in an alternative embodiment within a range between approx. 98.07 N - 980.7 N (10 kg - 100 kg), and - in a further alternative embodiment within a range between approx. 98.07 N -686.5 N (10 kg-70 kg).

Detailed explanation of what is shown in the drawing In fig. 1, an embodiment of a training apparatus 10, also called a drip foot machine according to the invention, with a user's foot 16 and tibia 15 is shown, but without loading.

The drop foot machine or exercise apparatus 10 is of the type consisting of an electric motor 5 which grips the base plate 3. Via a pivot point 1 at the rear of the base plate 3 a vertical rail 9 is mounted to the leg 15. The top of the vertical rail 9 is seated. yet another bracket 7 which allows entry and exit of the apparatus 10 in the illustrated embodiment, the bracket 7 being designed as an openable hinge capable of enclosing the tibia 15. At the same time, the bracket 7 also acts as an attachment 6 for the electric motor 5 so that it holds as far as possible on the apparatus 10 and thereby achieves maximum torque.

FIG. 2 shows the same as FIG. 1, but at full load, i.e. that voltage is applied to the electric motor 5, which thus acts with a force between the fastener 4 on the base plate and the fastener 6 at the top of the vertical rail 9, so that the electric motor 5 will contract the mechanical connection 20.

The electric motor 5 is controlled by a switch 13 shown in FIG. 3, and with which one can control the smallest movement, for example by operating a control button 14. All the electronics receive power ffa an inverter 12 which converts the voltage from 220 V to 12 V.

The clamping apparatus / training apparatus 10 is characterized by the use of an electric motor 5 rather than by hand. In addition, the apparatus maintains the tension in the calf muscle and the contact 13, 14 makes it possible to increase the tension. In FIG. 4 is a sketch drawing corresponding to the training apparatus, as shown in FIG. 1. In FIG. 5 shows a corresponding sketch drawing corresponding to FIG. 4, but illustrating an example of mounting the electric motor 5 on the back of the vertical rail 9. It will be seen here that the training apparatus / drip foot machine 10 will be easier to enter and exit, with the fastening 6 at the top of the vertical rail 9 not being will face forward, and the bracket 7 need not be designed as a hinge which goes around the leg 15. The engine tension 4 on the base plate 3 will be relatively close to the pivot point 1. The base plate 3 will be longer, i. extend rearwardly, and the vertical rail 9 will not stop at the rear of the base plate 3, but will be a bit inside the base plate 3. This will also result in a greater exchange of the engine, as no large travel is required to perform the same occupation.

FIG. 6 is a schematic drawing similar to FIG. 4, but illustrating an example of using an adjustable mechanical footplate 23.

With such a mechanical footplate 23 it is possible to adjust how high the base plate, or rather the mechanical footplate 23, which sits above the base plate 3, can be raised. This is only necessary if the desired migration of the base plate 3 itself is not sufficient. Alternatively, wedges have been used to increase the migration to get the desired effect, ie. wedges (not shown in the drawing) located above the base plate 3.
