Definitions
- a common tool is a pull rod that can be attached to a wall.
- One disadvantage of this instrument is that raising the body is too heavy an exercise to perform once or repeatedly for many.
- Another common tool is a frame to enable horizontal pull-ups.
- the body is pulled up from a wholly or partly horizontal body position, during which the feet continue to rest on the ground whilst lying on your back.
- the frame is fitted with handles above the user's upper body in order to perform a pull-up. Because the feet continue to rest on the ground during this exercise, the body weight is distributed across the arms and legs, making this less of a strenuous exercise than the one in which the entire body weight is pulled up.
- One disadvantage of the frame for horizontal pull-ups is that, if the exercise is performed with the legs stretched out, a horizontally directed force is exerted onto the feet, with this force working in opposite direction when pulling up and lowering the body. This horizontal force is caused due to the distance between the point at which the feet rest on the ground, and the handles of the frame remaining the same, while the distance between the hands and the feet becomes smaller, as the arms are moved towards the body from a position stretched out in front of the body. The horizontal force causes the feet to want to slide over the ground, as a result of which the exercise cannot be performed smoothly.
- a known solution is to perform the exercise with bent legs, during which the soles of the feet rest on the ground.
- one disadvantage of this form is that the body's center of gravity is closer to the feet compared to when the legs are stretched out, making the pull-ups less strenuous.
- the present invention aims to provide a training device that is suitable for pulling up your own body from a fully or partially horizontal body position, whilst not too strenuous for a person of average physical fitness and strength in order to repeat the exercise multiple times and not too easy to be tiring after a limited number of repetitions.
- the present invention makes it possible to pull up with legs stretched out from a fully or partially horizontal body position, without an alternating forward and rearward horizontal force being exerted onto the feet.
- a training device for pulling up your own body weight from a fully or partially horizontal body position, consisting of at least one or multiple uprights with at least two handles attached to it for the user's hands, a footrest where the feet can be pressed against, and a connecting piece between the uprights and the footrest, in which construction the handles can rotate towards the footrest with the center of rotation located below or close to the user's upper body, in such a way that the user can perform a pull-up while the feet remain pressed against the rest.
- the training device offers the option of making further adjustments so that the body can be pulled up in different ways. A number of such adjustments will be discussed later on in this document.
- the operating principle of the present invention is based on the rotation of the handles as described above, so that the user's feet remain pressed against the footrest whilst performing the pull-ups.
- the advantage of this principle is that the user's body is well-positioned, allowing the user to concentrate on the pull-up exercise.

- the preferred design in accordance with the present invention allows the connecting piece between the uprights and footrest to be adjusted in length, so that the distance between the uprights and the footrest can be adjusted to the user's height, or to the manner in which the user wants to perform the exercise.
- various tools known in the prior art which can serve as an adjustable connecting piece between the uprights and footrest. Examples of such known tools are: plates, pipes, tubes, ropes, belts, chains, rails, linear bearings, spindles and hydraulic or pneumatic cylinders.
- the connecting piece between the uprights and the footrest consists of a baseplate and ropes, chains or belts that can be adjusted in length, connecting the baseplate and footrest.
- the rotatability of the uprights is achieved by attaching the uprights to the baseplate by means of hinges. Since the feet are pressed against the footrest during the entire exercise, the connection between baseplate and footrest is acted on in one direction only, making it possible to use ropes, chains or belts.
- the advantages of ropes, chains or belts are that the dimensions of the baseplate and footrest can remain limited so that the training device takes up little space when not in use. Its limited volume is particularly important when the training device is used in a living environment. Another advantage of ropes, chains or belts is that the connection that has been established can be adjusted in length using basic tools.
- the footrest is connected to the baseplate at the same height as where the feet are supported. This prevents torque forces acting on the construction of the footrest so that the footrest can be constructed with a limited amount of material.
- two uprights are connected at the top by a rod, which is fitted with at least two handles.

Abstract
A training device for pulling up your own body weight from a fully or partially horizontal body position of which the operating principle is based on the rotation of the handles so that the user's feet remain pressed against the footrest whilst performing the pull-ups.
Description

- There are several tools known for body pull-ups. A common tool is a pull rod that can be attached to a wall. One disadvantage of this instrument is that raising the body is too heavy an exercise to perform once or repeatedly for many.
- Another common tool is a frame to enable horizontal pull-ups. In this exercise, the body is pulled up from a wholly or partly horizontal body position, during which the feet continue to rest on the ground whilst lying on your back. The frame is fitted with handles above the user's upper body in order to perform a pull-up. Because the feet continue to rest on the ground during this exercise, the body weight is distributed across the arms and legs, making this less of a strenuous exercise than the one in which the entire body weight is pulled up.
- One disadvantage of the frame for horizontal pull-ups is that, if the exercise is performed with the legs stretched out, a horizontally directed force is exerted onto the feet, with this force working in opposite direction when pulling up and lowering the body. This horizontal force is caused due to the distance between the point at which the feet rest on the ground, and the handles of the frame remaining the same, while the distance between the hands and the feet becomes smaller, as the arms are moved towards the body from a position stretched out in front of the body. The horizontal force causes the feet to want to slide over the ground, as a result of which the exercise cannot be performed smoothly. A known solution is to perform the exercise with bent legs, during which the soles of the feet rest on the ground. However, one disadvantage of this form is that the body's center of gravity is closer to the feet compared to when the legs are stretched out, making the pull-ups less strenuous.
- The present invention aims to provide a training device that is suitable for pulling up your own body from a fully or partially horizontal body position, whilst not too strenuous for a person of average physical fitness and strength in order to repeat the exercise multiple times and not too easy to be tiring after a limited number of repetitions. To this end, the present invention makes it possible to pull up with legs stretched out from a fully or partially horizontal body position, without an alternating forward and rearward horizontal force being exerted onto the feet. This objective is achieved by the present invention in the form of a training device for pulling up your own body weight from a fully or partially horizontal body position, consisting of at least one or multiple uprights with at least two handles attached to it for the user's hands, a footrest where the feet can be pressed against, and a connecting piece between the uprights and the footrest, in which construction the handles can rotate towards the footrest with the center of rotation located below or close to the user's upper body, in such a way that the user can perform a pull-up while the feet remain pressed against the rest.
- Furthermore, the training device, thanks to the present invention, offers the option of making further adjustments so that the body can be pulled up in different ways. A number of such adjustments will be discussed later on in this document.
- As such, the aim of the present invention has been achieved. The operating principle of the present invention is based on the rotation of the handles as described above, so that the user's feet remain pressed against the footrest whilst performing the pull-ups. The advantage of this principle is that the user's body is well-positioned, allowing the user to concentrate on the pull-up exercise.
- Example embodiments of the present invention will become more fully understood from the detailed description given herein below and the accompanying drawings, wherein like elements are represented by like reference numerals, which are given by way of illustration only and thus do not limit the example embodiments.

FIG. 12A andFIG. 12B are two side views of an alternative to the preferred design to illustrate a user performing a pull-up. - The preferred design in accordance with the present invention allows the connecting piece between the uprights and footrest to be adjusted in length, so that the distance between the uprights and the footrest can be adjusted to the user's height, or to the manner in which the user wants to perform the exercise. There are various tools known in the prior art which can serve as an adjustable connecting piece between the uprights and footrest. Examples of such known tools are: plates, pipes, tubes, ropes, belts, chains, rails, linear bearings, spindles and hydraulic or pneumatic cylinders.
- In the preferred design in accordance with the present invention, the connecting piece between the uprights and the footrest consists of a baseplate and ropes, chains or belts that can be adjusted in length, connecting the baseplate and footrest. The rotatability of the uprights is achieved by attaching the uprights to the baseplate by means of hinges. Since the feet are pressed against the footrest during the entire exercise, the connection between baseplate and footrest is acted on in one direction only, making it possible to use ropes, chains or belts. The advantages of ropes, chains or belts are that the dimensions of the baseplate and footrest can remain limited so that the training device takes up little space when not in use. Its limited volume is particularly important when the training device is used in a living environment. Another advantage of ropes, chains or belts is that the connection that has been established can be adjusted in length using basic tools.
- In the preferred design in accordance with the present invention, the footrest is connected to the baseplate at the same height as where the feet are supported. This prevents torque forces acting on the construction of the footrest so that the footrest can be constructed with a limited amount of material.
- In the preferred design in accordance with the present invention, two uprights are connected at the top by a rod, which is fitted with at least two handles. It prevents torque forces acting on the uprights and baseplate, partly thanks to the uprights having been hinged to the baseplate, so that the uprights and baseplate of the footrest can be constructed with a limited amount of material.
- In the preferred design in accordance with the present invention, the footrest is designed in such a manner that the feet are pressed against the rest whilst the heels are resting on the ground so that the exercise can be performed comfortably.

FIG. 8A andFIG. 8B show an alternative to the preferred design of the footrest of the present invention from two different perspective views.FIG. 8A shows a footrest with arotatable part 81 against which the user's feet can be pressed in two different random positions. The surface of themovable part 81 inFIG. 8A is ribbed so that the user's feet cannot slip.FIG. 8B shows the other side of the footrest from which it is clear that therotatable part 81 is connected to ashaft 83 by means of twobearings 82. Theshaft 83 is connected to either side of theuprights 22, which are attached to abaseplate 21.FIG. 8A andFIG. 8B partially show thecords 16 which are connected to the footrest by twoeye bolts 17 andknots 18. - Alternatively, or additionally, a training device in accordance with the present invention can be fitted with a footrest with a part against which the user's feet can be pressed and which consists of a cushion filled with a gas (mixture), liquid (mixture) or elastic material. An example of an elastic material as referred to in the preceding sentence is foam rubber. This cushion enables the user's feet to rotate with the movement of the body whilst pulling up.
- Alternatively, or additionally, a training device in accordance with the present invention can be fitted with uprights which, by means of one or multiple tools, enable the user to change the distance between the handles and their center of rotation, i.e. the height of the handles. There are various tools known in the prior art which make it possible to change the height of the handles. One example of a common tool is for each upright to be composed of two telescoping tubes or pipes, which can be fixed at different positions in relation to each other. Another example of a common tool involves a number of holes at different heights in each upright, in which a locking pin can be inserted at the desired height. Subsequently, a bracket can be attached to this locking pin, which serves as handle. One advantage of changing the height of the handles is that this allows the training device to be adjusted to the user's physical dimensions, or to the manner in which the user wishes to perform the exercise.
