Mobile device extension for training equipment

Abstract

The invention relates to a mobile device extension for training equipment that enables targeted intensification of the eccentric training phase. The extension consists of a base plate, a motor housing with drive shaft, motor and control unit mounted on it, and a belt or cable system. By manually operating a hand or foot switch, the user can increase the resistance during the downward movement while the exercise is in progress, as the weight is additionally pulled downwards by a motor. The design allows for flexible use on various training devices without permanent screw mounting, thereby increasing the training effect. The device extension is modular, portable, and allows for the operation of several devices in series via an integrated power outlet.

Description

Technical Field:In order to comprehensively train its body, there are concentric and eccentric training in the training science.Most training equipment and methods available carry out concentric training. The intensity of this movement is increased by the use of weights / weight stacks or other resistors such as rubber ropes or the like.In conventional training equipment with weight stacks or other resistors, the user must apply the same force to gradually raise the weight stack as to gradually lower it. During the weight stack lifting phase of a exercise, the involved muscles contract or contract, which entails concentric muscle movements; during the weight stack lowering phase, the involved muscles lengthen, which entails eccentric muscle movements.Therefore, such conventional training devices with weight stacks or other resistances are limited to providing eccentric muscle movements with the same resistance as concentric muscle movements. However, muscles can generate significantly more force in eccentric (muscle-lengthening) training movements than in concentric (muscle-shortening) training movements.This difference between concentric and eccentric movements was detected and different approaches were followed to produce increased resistance to eccentric movements.In order to perfect the training effect of the eccentric movement, when the training person drops / returns the weight, the training weight would have to be increased in the course of the training movement, so that the training person can work more strongly against the weight dropping and tries to hold it up temporarily.An increase in weight during a running training movement can hardly be achieved with the available training possibilities.Prior Art:In force training, the eccentric phase, i.e. the controlled lowering of the weight, is often neglected, although it plays an important role in muscle construction. Although previous training devices are designed to allow the sportian to control the weight manually, there is a lack of a device that specifically supports and reinforces the eccentric phase.There are already inventions / solutions which have to be screwed firmly to the respective training devices and a training weight change cannot be carried out manually by the training person when required during the ongoing training movement.It is usually intelligent, digital training systems with dynamic force modules which, with a plurality of sensors, monitor the training or the movement of the sports person and then adapt (increase or reduce) the training weight independently. The training person cannot automatically manually change the training weight as needed.Supplementary Illustration of the Known Prior Art• DE 10 2006 052 502 A1 describes a force training device with an additional module which generates an additional force when the weight stack is lowered. The force is transmitted via an electric motor and a cable drum and is increased in a central region of the movement path. The control is effected automatically via sensors. The additional module is mechanically connected to the training device, a free-standing or mobile use is not provided.• DE 10 2018 220 953 A1 discloses an auxiliary drive for training devices which makes possible a dynamic adaptation of the load by means of force sensors and a control unit. The load is automatically controlled and can be adapted to physiological parameters in real time. Manual control by the user is not provided. The assembly takes place integrally or as a conversion kit, wherein a fixed connection to the training device is necessary. A free-standing, flexible application is not described.• US 2010 / 0 279 821 A1 shows a training system with sensors for force and position measurement and a motor for moving training components. The control is effected via a central control device which automatically adjusts the training parameters. The components are fixedly installed in a frame which forms the entire training structure. A mobile extension or free-standing solution is not part of the disclosure.• US 5 328 429 A describes an apparatus for asymmetric force application in training devices with a weight stack. The device specifically increases the load in the eccentric phase by means of an electric motor and microcontroller. Control is automatic based on sensor data. The device is mechanically attached to the existing device, e.g. via cables or belts. The assembly is not free-standing, but requires a fixed integration into the training device• WO 2012 / 176 165 A2 discloses a modular exercise apparatus with variable resistance adjustment. The resistance is increased during the eccentric phase via a motor and a control system. The adaptation is automatic and cannot be controlled by the user. The modules are provided for fixed mounting on existing equipment. A free-standing, non-screwed application is not described.Object of the invention:The object of the invention is to provide a mobile extension for training devices which is not screwed to a training device and which makes the eccentric movement phase of a training more intensive by virtue of the resistance being able to be activated manually by the training person in a targeted manner during this phase and the training weight being able to be increased.Solution according to the invention:This is followed by the mobile device extension.The mobile device extension consists of a base plate (1), a motor crate (2) which is fastened on the base plate (1), a hand / foot switch (3) and a cable or belt (4) which is connected to the training device.Self-standing training devices with a weight block, on which the training weight can be adjusted by means of a locking pin or the like, as well as so-called flattened-loaded training devices and training banks with long-hungel rods, are placed on the floor plate ( 1) of the mobile device extension without any further screw connection.The respective training apparatus is not connected to the base plate (1) and stands completely freely on the plate.For visual reasons, the base plate (1) has exactly the dimensions of the upstanding training device in order not to protrude. However, large dimensions / protrusions can also be implemented.The floor panel (1) can be made of a wide variety of materials such as wood, metal, plastic, and the material thickness can also vary.In (2): the motor box consists of a drive shaft (2.1), a motor (2.2), a motor controller (2.3), optionally a motor cooling system (2.4), a mechanical end position switch (2.5), a switched-mode power supply and a separate socket (2.6). The motor box (2) is fixed on the bottom plate (1).In (2.1): To the drive shaft, which is made of metal and is connected to a (2.2) electric motor, pneumatic or hydraulic drive and is rotated by the latter, one or more belts or cables are fastened, which are drawn in / rolled in or rolled out by the rotation of the drive shaft. The drive shaft (2.1) is not fixedly and rigidly installed, but rather has a certain degree of mobility in order to be able to activate the end position switch (2.5)In (2.2): The drive / rotary motion for the drive shaft (2.1) generates an electric motor. Pneumatic or hydraulic drives are also possible.Referring to (2.3), the motor control consists of a changeover circuit with which the left and right rotations of the motor (2.2) can be controlled. In addition to the motor (2.2), a hand or foot switch is also connected to the control in order to control the motor (2.2) and an end position switch (2.5) in order to limit the rotational movement of the motor with an end position.In (2.4): The motor (2.2) is cooled for temperature regulation. For this purpose, the motor ( 2.2) is surrounded by an aluminum cooling body for the purpose of heat dissipation, to which a water cooling system is connected. The water cooling system consists of a water pump, a fan with cooling ribs and a temperature switch. For this purpose, the temperature switch switches on the water pump and the fan from a certain temperature and starts the cooling circuit. The cooling circuit functions by water flowing from the water pump to the aluminum cooling block of the engine (2.2) for cooling, absorbing heat generated there, transporting it to the fan, which cools the water via the cooling ribs with an air flow.For (2.6): The integrated socket (2.6) makes it possible to connect further devices one behind the other (series connection). It is thus possible to be able to operate a plurality of device extensions without requiring a separate socket on the wall for each device. This is therefore a solution which reduces the cabling outlay and facilitates the connections of a plurality of devices via a single power source.In (2.5): the mechanical end position switch controls the opposite rolling direction as the hand switch or foot switch. This functions by the training person using the training device, pulling the belt / s or cable / s to tension by the training movement, thus pressing the drive shaft (2.1) somewhat forwards and activating the mechanical end position switch. The motor (2.2) is then supplied with voltage. If the belt or cable tension subsides, the drive shaft (2.1) is pressed back somewhat again by a spring / rubber / foam material or the like, the end position switch is then no longer touched by the drive shaft (2.1) and the motor stops again.In (3): With the hand switch or foot switch, the rotational movement of the motor (2.2) is manually activated and controlled by the training person. As the foot switch is operated, the motor rotates in a predefined direction. If the hand switch is no longer pressed, the motor stops.In (4): The belt / s or cable / s used is made of textile, wire, plastic or the like and is surrounded by a flexible and stretchable protective tube for cable guidance.The protective hose is not connected to the drive shaft (2.1), but is fastened only to the base plate (1). This ensures that only the belt / s or cable / e is rolled up or pulled in by the drive shaft (2.1).Explanation of how the free-standing training device is connected to the mobile device extension:Training Equipment with Weight Block / Stack:In order to connect the training device with weight block / stack to the mobile device extension, the weight block is wound around with a belt / cable (4).Both belt / cable ends are connected to the drive shaft (2.1) and are guided from the motor box (2) over at least two deflection rollers integrated in the base plate (1) from below, coming from the front and back over the weight block / stack, so that the latter is surrounded by the belt / cable.For reasons of mobility for the mounting and dismantling of the mobile device extension, the belt / cable (4) is halved in length and both ends are connected via a belt buckle (FIG. 7).By means of this belt buckle, the belt / cable (4) which wraps around the weight block / stack can be quickly and easily released and the mobile device extension can be removed.Plated Loaded Training DevicesIn order to connect the flattened loaded training device to the mobile device extension, the two weight-receiving devices for dumbbell disks are each wrapped around by a belt / cable ( 4).Both belt / cable ends are connected to the drive shaft (2.1) and are guided from the motor box (2) via at least two deflection rollers integrated in the base plate (1) from below to the weight-receiving device, the belt / cable end is wound into a loop or the like and this loop is connected to the weight-receiving device.Dumbbell Banks with Langhantel Rod:In order to connect the dumbbell bench with the elongated bar to the mobile device extension, the elongated bar is wrapped around on the left and right with a belt / cable ( 4), respectively.Both belt / cable ends are connected to the drive shaft (2.1) and are guided from the motor box (2) via at least two deflection rollers integrated in the base plate (1) from below to the elongated bar, the belt / cable end is wound into a loop or the like and this is connected to the elongated bar.Mobile Device Extension Functionality:By manual actuation of a foot / or hand switch (3) by the training person, the cable / cable or belt / cable (4) can now be drawn in during a running training movement, in that, when the foot / hand switch (3) is actuated, the installed motor (2.2) rotates the drive shaft (2.1) and the belt / cable or cable / cable (4) is thus rolled up or drawn in.Since the weight block of the training device, the weight receiving devices for dumbbell disks or the elongated dumbbell bar is connected via the belt / -e or cable / -e (4) to the drive shaft (2.1) of the mobile device extension, the weight block, the weight receiving devices for dumbbell disks or the elongated dumbbell bar is pulled downward upon cable retraction and the training person must work against the pulling down and attempt to hold it against the pulling down for as long as possible.By the motorized retraction of the belt, the load in the eccentric phase is increased. This has the consequence that the sport person has to work more intensively in this phase, which leads to an improved muscular stress and an increased training effect. The training weight in the eccentric phase can be increased by up to 70 kg by the motorized support. The increase in the training weight takes place continuously and increases depending on how the training person is counter-holding.When the foot / hand switch ( 3) is released by the training person, the cable retraction is immediately stopped and the motor ( 2.2) remains stationary.A mechanical end position switch (2.5) controls the opposite direction of rotation of the motor (2.2) so as to unroll the belt / cable / cable again. For this purpose, the training person must use the respective training device again, carry out the respective training exercise and push up the weight block or the other weight or the elongated rod in order for the cable or the belt to be pulled to tension, the mechanical end position switch to be activated therewith and the motor starts to rotate.As soon as the cable or belt (4) is no longer sufficiently tensioned, the motor (2.2) stops this rotational movement again.This ensures that the required freedom of movement of the training device is always present, even if the function of the mobile device extension is not used by the training person.The freedom of movement of the training device is not restricted by the cable or the belt (4).Furthermore, the cable or belt ( 4) is not unrolled / unwound from the drive shaft ( 2.1) more than necessary.Advantages of the Invention:The intensity of the eccentric motion phase is increased by the targeted use of the motor, which leads to an improved training effect.The mobile design allows flexible application to different training devices, which makes the field of application of the invention versatile.Mobile is understood to mean that mobile device extension can be used quickly & easily by other training devices. For this purpose, only the desired training device needs to be placed on the base plate (1) and the belt / cable / cable (4) of the mobile device extension needs to be connected to the training device standing thereon.Also, instead of displacing the complete base plate, only the motor box can be removed from the base plate and screwed to another base plate.A further advantage of the invention is that the device is equipped with a separate socket, thereby providing the possibility of connecting several devices in series. This significantly reduces the cabling outlay, since only the first device has to be connected to a conventional socket and all further devices draw the required power supply from a device placed in the vicinity. This arrangement allows space-saving and resource-saving use of power connections and increases the flexibility of the installation.
