Description

The invention relates to a training device with a gripping body and a wrist attachment.

A wide variety of training devices are available today for exercising the hands, arms, and shoulders. For example, there are kneading balls that you can hold in your hand and knead. This trains the hand and arm muscles. They are also said to have a stress-relieving effect. Wrist weights are also available, which can be worn while hiking or jogging, for example, to provide additional training for the hands, arms, and shoulders. Poles are also known for use in Nordic walking and hiking. These serve not only as support, but also to engage the arms and associated muscles while hiking, thus providing an additional, positive training stimulus.

Based on this, the invention is based on the object of providing a training device with which in particular the hands, arms and shoulders can be trained in a simple manner at any time and in any place.

The object is achieved by a training device according to claim 1. Advantageous embodiments are specified in the dependent claims and the description, wherein different embodiments can be combined with one another.

The training device according to the invention comprises a gripping body which can be grasped with one hand and which has an upper and a lower end, and a wrist attachment which has a connecting section connected to the upper end of the gripping body, wherein the connecting section runs between the thumb and index finger and, when the hand is open, holds the upper end of the gripping body close to the palm of the hand, so that the gripping body hangs freely swinging on the connecting section and can be grasped by closing the hand, wherein the circumference of the gripping body at the upper end is smaller than the circumference of the gripping body at the lower end.

Unless otherwise stated, the following description refers to a state in which the wrist attachment is attached to the wrist of a user's hand and the palm is facing downwards at an angle. For example, the arm with the hand can be stretched out horizontally in front of the user. The gripping body is positioned between a floor on which the user is standing and the palm of the hand. The palm can, for example, be at an angle of 45 degrees to the floor. In this state, with the hand open, the gripping body is held close to the palm of the hand. Close to the palm of the hand means that the gripping body can be easily gripped when the hand is closed, which can be the case when there is a distance of a few centimeters, for example three centimeters or less, between the gripping body and the palm of the hand.

In principle, the gripping body can be any physical object that can be grasped with one hand and whose circumference is smaller at the upper end than at the lower end. In particular, the circumference of the lower end is at least twice as large as the circumference at the upper end, for example, at least 2.5 times or at least 4 times as large.

The shape of the connecting section between the thumb and index finger allows the gripping body attached to the connecting section to swing freely around the point where the connecting section no longer makes contact with the hand. In particular, the connecting section runs along a portion of the outer surface of the hand and can be located between the thumb and index finger in a transition area between the back of the hand and the palm of the hand.

The gripper body can be repeatedly grasped and released by hand. The wrist attachment prevents the gripper body from falling when not gripped. The path of the connecting element between the thumb and index finger also ensures a relatively defined position of the gripper body when not gripped, allowing it to be grasped again at any time.

By repeatedly grasping and releasing the gripping body, you can train your hand, arm, and shoulder in a simple and intuitive way. To increase the training effect, the training device can be moved with your arm, with the weight of the gripping body providing an additional training stimulus. It is also possible to use the training device while hiking or walking or while training on a treadmill – as well as anywhere indoors, at work, while sitting or lying down. Because the training device does not have to be placed on the ground, you can aim your arms and the held training device at treetops or similar landmarks to create an additional fun moment with the training device. The training device can therefore be used in a variety of ways. can be used in various locations, whereby the repeated grasping and releasing as well as the associated movement generally also serves to reduce stress.

In one embodiment, the circumference of the gripping body is so small at the upper end that it can be encircled by the thumb and index finger. This makes the gripping body particularly easy to grasp without cramping the hand, because it is in a natural position when holding the gripping body.

In one embodiment, the circumference of the gripping body at the lower end is large enough for the palm and little finger to enclose the gripping body over a circumferential area of 270° or less. This dimensioning allows the hand to be held in a natural position while gripping the gripping body, thus preventing cramping.

In one embodiment, the gripping body is conical.

On the one hand, a conical shape allows the gripper to be easily grasped, achieving a natural hand position that prevents cramping. On the other hand, a conical gripper is relatively easy to manufacture and offers an attractive design.

In one embodiment, the gripping body has a circular base at its lower end. The base can be designed to form a continuous, uninterrupted surface. The base seals off the gripping body at the bottom. A circular surface is conducive to a natural closed hand position, which prevents cramping. Furthermore, the training device can be easily placed on the base.

In one embodiment, the gripping body has a shell and a filling. The shell can be, for example, a natural latex bladder in which the filling is protected from moisture and encapsulated. The shell can be designed to be deformable. In particular, it can be bendable and/or stretchable. The shell and the filling can together have a weight of less than one kilogram, less than 750 grams, or even less than 500 g. The filling can be composed of a deformable material, whereby deformation can be caused by gripping with the hand. The material can have elastic properties. Starting from a deformed state, it can return to its original state within the framework of elastic deformation. It can be rubber, for example. However, it can also be a material that remains at least partially in the deformed state after deformation. For this purpose, it can also be supported by the shell. It can be, for example, modeling clay, a gel, or granules. The gripping body can be deformable as a whole. The deformability of the gripping body allows for particularly effective training because, when gripping the gripping body, the hand works against a resistance that is at least partially deformable and changes as it does so. This also increases the stress-reducing effect. The construction of a shell and a filling allows for the use of different fillings, so that the gripping body can be adapted to different preferences, for example, or simply provided in different versions.

In one embodiment, the shell consists of at least two parts, with an upper part forming the outer surface of the cone and a lower part forming the base surface of the cone. This makes it particularly easy to fill the shell with the filling by first inserting the filling into the upper part, and then the lower part sealing the upper part.

In one design, the upper and lower sections are sewn together. This allows for easy connection. The seam also provides a visually appealing design feature.

In one embodiment, the cover is made of leather, latex, especially natural latex, or a textile. These materials are characterized by high durability and a pleasant feel. Furthermore, they can be customized in various colors and with various prints or inscriptions. These materials also allow for deformability, which, as described above, can improve training success. The materials can also be selected to exhibit stretchability, which further supports the deformability of the gripping body.

In one embodiment, the filling is formed by metal balls and/or sand. The metal bodies can be smaller than two millimeters or even smaller than one millimeter. Metal balls and sand as a filling form a type of granulate. After deformation by gripping the gripping body, the gripping body remains deformed within a certain range, whereby the degree of deformation can be controlled by the material of the shell. This can produce particularly pleasant haptic properties that lead to This contributes to a particularly pleasant workout. Furthermore, these materials are readily available and can be processed without difficulty.

In one embodiment, the wrist attachment has a hand strap for attaching to the wrist. The hand strap can be at least partially designed as a strap or band. The hand strap allows for easy attachment to the wrist and removal. It also prevents the gripping body from falling off the wrist. Furthermore, the hand strap allows the connecting element to be easily guided over the area between the index finger and thumb, allowing the gripping body to swing freely in the correct position.

In one embodiment, the wrist strap features a pin buckle. Different holes can be provided for the pin buckle, resulting in different wrist strap circumferences when the pin buckle is closed. This allows for a selection of sizes and effectively prevents the gripping element from slipping off the wrist during training without compromising comfort due to cutting in. A pin buckle also allows for easy putting on and taking off.

In one embodiment, the connecting portion has an eyelet attached to the gripping body. The gripping body can have a connecting tab that is connected to the gripping body near its upper end and is guided through the eyelet. Attaching the gripping body with an eyelet allows the gripping body to move relative to the eyelet. This ensures that the gripping body, when released, swings freely, ensuring that it always hangs straight down and is conveniently positioned for easy access. The eyelet also prevents premature wear of the wrist attachment.

In one embodiment, the wrist strap is threaded through the eyelet. This makes attaching the wrist strap to the gripper body particularly simple, requiring only a single eyelet. A certain degree of relative movement between the wrist strap and the eyelet is also possible, supporting free swinging.

In one embodiment, the eyelet is designed as a D-ring with a straight and a curved section, with the straight part of the eyelet being attached to the gripping body. A D-ring describes a ring formed from a straight and a curved part, with the straight part being arranged between a first and second connection point of the curved part. The attachment of the gripping body to the straight part of the D-ring allows the gripping body to swing around the straight part, but is otherwise fixed. This makes the gripping body easy to grip, but still offers mobility to increase training success.

In one embodiment, the wrist strap is threaded through a tab that rests on the back of the hand. This tab allows the weight of the gripping body suspended from the wrist attachment to be better distributed across the back of the hand. It also allows the wrist strap to be guided in a targeted manner, making it comfortable to wear and ensuring the wrist attachment is securely attached to the wrist.

In one embodiment, the strap has two threading points for the wrist strap, whereby the strap can be positioned in the area between thumb and index finger so that the wrist strap forms a triangle with one corner facing the gripping body and two sides leading to the wrist. The wrist strap can be guided in two strands that form two sides of the triangle. This allows for targeted attachment of the gripping body. The wrist strap converges in the area of the eyelet attached to the gripping body, so that the gripping body is suspended approximately at only one point or in a narrowly defined area defined by the eyelet. This ensures that the gripping body swings freely only in a desired area, which improves the training effect. On the other hand, the two parts of the wrist strap are guided around the wrist, resulting in a particularly secure attachment. In addition, the guide prevents the strap from cutting in, and wearing comfort is increased.

In one embodiment, the wrist strap is held in a movable position at the threading points. The tab can be moved relative to the area between the thumb and index finger. This movable attachment allows the tab to be positioned precisely so that the strands of the wrist strap converge in the area between the thumb and index finger, enabling the desired positioning of the gripping body. The tab can be moved to accommodate individual hand sizes, thus increasing comfort.

In one embodiment, each threading point has two parallel slots through which a section of the hand strap is threaded. The hand strap can be threaded through both slots in one strand. The two parallel slots make it easy to hold the tab slidably relative to the hand strap.

In one design, the strap is trapezoidal. The trapezoidal shape mirrors the triangular guide of the wrist strap and thus supports the guidance of the strap's strands. It also offers an attractive design.

In one version, the wrist strap features a leather strap. Leather is characterized by its high durability, pleasant tactile properties, and attractive appearance.

The invention will be explained in more detail below with reference to an exemplary embodiment illustrated in the accompanying drawings. In the drawings, the following figures show:

• 1 a view of the training device in a non-wearing state,
• 2 another view of the training device in a non-wearing state, showing the tab from below,
• 3 how to position the training device correctly on the hand,
• 4 how the wrist strap is attached to the pin buckle,
• 5 a movement of the training device away from the body and
• 6 a movement of the training device towards the body.

1 shows a view of the training device 1 in a non-wearing state. The training device 1 comprises a gripping body 2, a wrist attachment 3, and a connecting section 4 with which the wrist attachment 3 is attached to the gripping body 2.

The gripping body 2 has an upper end 5 and a lower end 6, with the gripping body 2 having the shape of a cone between them, which has the outer surface 7 and the base surface 8. They form a shell filled with a granulate.

The wrist attachment 3 has a wrist strap 9 formed by a strap and attached to the connecting portion 4. The wrist strap 9 has a pin buckle 10 at one end and holes 11 at another end for attaching the pin buckle 10. Furthermore, a trapezoidal tab 12 is attached to the wrist strap 9. This tab has two threading points 13 (only one is provided with a reference symbol) through which the wrist strap 12 is threaded. The threading points 13 are each formed by two parallel slots 14 (only one is provided with a reference symbol). The tab 12 is movable relative to the wrist strap 9. The threading points 13 are arranged on the flap 12 such that the hand strap 9 extends in two strands away from the flap 12, the strands forming a triangle and the area of the hand strap 9 between the threading points 13 forming the tip of the triangle and the two strands forming the sides of the triangle.

The connecting section 4 has an eyelet 15 to which the gripping body 2 is attached by a connecting tab 16, the connecting tab 16 being placed around the eyelet 15 and attached with its two free ends to the gripping body 2. The hand strap 9 is also guided around the eyelet 15 in its section that runs between the two threading points 12.

2 shows another view of the training device 1 in a non-wearing state, viewed from below. It is clearly visible how the wrist strap 9 is guided through the threading points 12, each of which is formed by the two parallel slots 14.

3 shows how the training device 1 is correctly positioned on the hand 17. To do this, the tab 12 is positioned on the back of the hand so that the hand strap 9, in its section that runs between the threading points 13, is arranged between the thumb and index finger. The corresponding area is marked by the displayed arrow. As a result, the eyelet 15, with which the gripping body is attached to the hand strap 9, is also arranged in this area between the thumb and index finger. In this view, the eyelet 15 can be identified as a D-ring, with the connecting tab 16 being placed around a straight part of the D-ring. The holding body 2 is arranged on the inside of the hand. By positioning the eyelet 15 formed by the D-ring, the gripping body 2 can swing freely forwards and backwards in an imaginary extension of the arm when the hand is open.

4 shows how the wrist strap 9 is attached to the wrist with the pin buckle 10, whereby the positioning of the tab 12 (not visible in this view) remains unchanged, so that the gripping body 2 remains arranged on the inside of the hand 17. Using the pin buckle 10 and the holes 11, the circumference of the wrist strap 9 is adjusted to the wrist circumference, so that the training device 1 is attached to the hand 17 with the wrist attachment 2.

5 shows a movement of the training device 1 away from the body, with this direction of movement being indicated by the arrow. During this movement, the hand 17 is opened and the gripping body 2 is released. The gripping body 2 then hangs on the hand strap 9, which runs between thumb and index finger, so that the gripping body 2 also in the area which is in 3 This can be clearly seen, is suspended in a freely swinging manner. Such a movement of the training device 1 away from the body can be performed, for example, while walking, if the corresponding arm is moved in counter-clockwise direction to the opposite leg.

6 shows a movement of the training device 1 toward the body, with the direction of movement indicated by the arrow. When moving backward, the hand 17 is closed and the gripping body 2 is grasped. This movement can also be performed while walking if the arm is moved in the opposite direction to the walking direction.

This view also clearly shows that the index finger and thumb completely enclose the upper part 5 of the gripping body 2 and even overlap. The little finger, however, cannot completely enclose the lower part 6 of the holding body 2 and is partially positioned below the base 8. This allows the hand to remain in a natural position when gripping.

The 5 and 6 The movement shown represents a way of using the training device 1, which can be used, for example, while walking. However, these movements can also be performed during other activities, for example, while sitting or standing.
