Description

The present invention relates to a deadlift device.

It has long been known to train one's own physical performance and thus also one's own health in order to maintain or improve it. Physical performance is also referred to as fitness and the corresponding training as fitness training. The fitness training is assigned to the leisure sports activities. The exercises in fitness training, also called fitness exercises, can be used for endurance training, strength training, mobility training and coordination training, with one or more of these types of training being addressed depending on the fitness exercise.

One of the more popular strength training exercises is the deadlift. In this strength exercise, a person lifts a weight lying on the floor from a bent over, stable position. This exercise is usually performed with a barbell bar, which has weight plates fixed on the left and right ends of the barbell bar as weight plates.

The fitness exercise of the deadlift is popular because almost the entire body, i.e. many muscle groups at the same time, can be trained with just one exercise. In particular, the muscles in the back and in the legs are trained together. The deadlift can therefore also be viewed as a full-body exercise or compound exercise.

However, when using straight barbells with weights as described above for the deadlift, the disadvantage for the person is that the barbell must be lifted in front of the body and guided past the body, especially the knees and shins. This can possibly lead to injuries to the knees and shins.

In particular, this movement sequence of lifting is stressful for the back, since lifting from the squat does not have to be in a straight line in the vertical but initially at an angle in order to lift the barbell off the floor in front of the body and pass it.

The DE 298 17 999 U1 describes a training device, in particular in the form of a dumbbell, with a vertical top view of a substantially U-shaped, circular or frame-shaped, open, closed or closable carrier made of a solid material. Fastening means are provided on the carrier for carrying the training device, which consist of two carrying straps or shoulder straps mounted opposite one another on the carrier. Furthermore, holding elements are attached or attachable to the carrier on two opposite side sections, on which additional weights can be placed or attached. Using the training device DE 298 17 999 U1 For example, a person can lift the weights by crouching inside the carrier, placing the risers or shoulder straps over the shoulders, and then rising to standing.

The disadvantage here, however, is that the arms are not used in this exercise and are therefore not trained. This is structurally impossible. Thus, the training device of the DE 298 17 999 U1 not to be used for the fitness exercise of the deadlift.

An object of the present invention is to provide a deadlift apparatus of the kind described in the opening paragraph, which can improve the performance of the deadlift fitness exercise for the person. In particular, it should be possible for the person to carry out the deadlift fitness exercise without being able to come into contact with their own knees and/or shins. In particular, the deadlift device for the deadlift should be able to be gripped optimally by the person in addition or as an alternative. At least an alternative to the well-known possibilities of deadlifting should be created.

The object is achieved according to the invention by a cross lifting device with the features of the independent claim. Advantageous developments are described in the dependent claims.

Thus, the present invention relates to a deadlift device. A deadlift device is to be understood as a device which is specially designed for one person to carry out the fitness exercise of the deadlift, although this does not rule out the possibility that the deadlift device according to the invention can also be used for other fitness exercises.

The deadlift device has a frame with a frame box, which surrounds a frame interior at least essentially, preferably completely, in a closed manner. The frame can also be referred to as a frame. The frame box surrounds the frame interior in the horizontal at least in sections, ie open at one point in the horizontal, or completely closed. In any case, the area or the area in the horizontal, which is partially or completely enclosed by the frame box, can be referred to as the frame interior. In particular, the frame box can be rectangular, round or oval.

The interior of the frame is designed to accommodate a person performing the deadlift fitness exercise. Thus, the interior of the frame and thus also the frame box has a shape or an extent such that a person can stay in the interior of the frame and, being there, can carry out a deadlift process with the deadlift device. In particular, due to the shape or due to the extent of the frame box of the deadlift device, it can be avoided that the person can come into contact with the frame box when performing the fitness exercise of the deadlift. The deadlift device according to the invention can therefore also be referred to as a barrier-free deadlift device.

The deadlift includes a pair of gripping members that are configured to be gripped by one of the person's hands, respectively. The deadlift device can thus be grasped or held and lifted by the person by means of the handle elements when the person performs the deadlift operation. As a result, the arms can be involved in the execution of the deadlift fitness exercise in order to also train the arms using this fitness exercise.

The handle elements are each arranged in the longitudinal direction in the center of gravity of the deadlift device, preferably its frame, on the frame, preferably on the frame box. In other words, the handle elements of the deadlift device are positioned on its frame and preferably on its frame box in such a way that the person can enter the interior of the frame, grip the handle elements with their hands from above and lift the deadlift device from a squatting position to an upright position. Viewed in the longitudinal direction, the center of gravity of the deadlift device is always there where the handle elements are arranged in the longitudinal direction on the frame or its frame box. For this purpose, the handle elements can be arranged in the middle of the frame or its frame box in the longitudinal direction.

This can enable the person to at least substantially coincide their own center of gravity in the longitudinal direction with the center of gravity of the deadlift device, preferably its frame. Sitting in a crouch, the person can thus align the insides of the elbows parallel to the knees. Thus, the person can perform the deadlift fitness exercise in such a manner that the lifting of the deadlift device can be done accurately in the vertical direction, which can be easy on the person's back.

The deadlift device or its frame can preferably also be designed so that the center of gravity of the deadlift device, preferably its frame, is also arranged on the frame, preferably on the frame box, so that when the deadlift fitness exercise is carried out, the center of gravity of the deadlift device is also located , preferably its frame, in the transverse direction at least substantially in line with its own center of gravity can be brought. This can prevent the person from laterally skewing or uneven loading in the transverse direction when performing the deadlift fitness exercise.

In any case, the frame box extends in the transverse direction beyond the shoulders of the person on both sides, so that the handle elements can be gripped by the person from above and past the side of the body. Also, the frame box extended in the longitudinal direction in front of and behind the person's body enough to surely avoid contact of the frame box with the person when performing the fitness exercise of deadlift, especially when the person is crouching.

The fitness exercise of the deadlift can be carried out solely with the weight of the frame of the deadlift device according to the invention, which can be correspondingly structurally specified. However, it is preferable to be able to attach additional weights and in particular weight plates to the deadlift device in order to be able to increase the weight to be lifted for the fitness exercise of the deadlift and in particular to be able to adjust it as desired by the person.

Carrying out the deadlift fitness exercise by using a deadlift device according to the invention can support the natural movement sequence. The muscles of the person can react appropriately and be optimally challenged. According to the invention, the course of the exercise can thus be adapted to the musculature of the person and support the natural course. This can prevent the risk of injury. This applies to the lower back as well as to the muscles otherwise affected. Possible injuries from conventional equipment such as bruises, strains, compressions, tears, fractures and the like can be avoided.

In any case, the deadlift device according to the invention can be used for competitive sports, for leisure sports and for rehab, i.e. for rehabilitation.

According to one aspect of the invention, the handle elements can each be rotated about their vertical axis, which extends in the vertical direction, relative to the frame, preferably relative to the frame box. This can make it possible for the person to set the grip elements around their vertical axis in a desired orientation, rotational position or angular position. For this purpose, the handle elements can be held in the vertical direction on the frame and preferably on the frame box and rotated about their vertical axis.

This can make it possible, in particular, to align the grip elements with respect to the person in such a way that the palms of the hands and the elbows of the person point slightly outwards, which is important for the person Performing the deadlift fitness exercise can represent an optimal position of the hands or arms. This can also be preventative against injuries during training.

According to a further aspect of the invention, the grip elements can each be fixed in a rotational position. This can enable the person to fix a desired or specific orientation, rotational position or angular position in order to be able to securely maintain this orientation, in particular while performing the deadlift fitness exercise. The fixing can take place by means of suitable mechanical means in a form-fitting and/or force-fitting manner. This can be done, for example, by latching, clamping, tensioning and the like.

According to a further aspect of the invention, the handle elements each have a handle body, which is preferably essentially curved and open at the top, which is arranged vertically above the frame, preferably the frame box, and a pair of handle holders, which are each connected by a Through-opening of the frame, preferably the frame box, are connected through to one of the two handle elements. The handle holders are preferably each arranged vertically below the frame, preferably the frame box. This can enable a concrete implementation of the corresponding aspects according to the invention described above.

According to a further aspect of the invention, the handle holders are each designed to loosely or non-positively hold the respective handle element in the vertical direction on the frame, preferably on the frame box, about its vertical axis, which extends in each case in the vertical direction. This can enable a concrete implementation of the corresponding aspects according to the invention described above.

According to a further aspect of the invention, the handle holders are each designed to be rotated about their vertical axis together with the respective handle element relative to the frame, preferably relative to the frame box. This can enable a concrete implementation of the corresponding aspects according to the invention described above.

According to a further aspect of the invention, the handle holders are each designed to positively fix the respective handle element relative to the frame, preferably relative to the frame box. This can enable a concrete implementation of the corresponding aspects according to the invention described above.

According to a further aspect of the invention, the handle holders are each through the through-opening of the frame, preferably the frame box, through by means of an external thread with a Screwed internal thread of the respective handle element. This can enable a concrete implementation of the corresponding aspects according to the invention described above.

According to a further aspect of the invention, the handle holders each have a rotary handle which is designed to be gripped by one of the person's hands in order to rotate the handle holder relative to the respective handle element, preferably its handle body. This can enable a concrete implementation of the corresponding aspects according to the invention described above.

According to a further aspect of the invention, each handle element has a handle which is connected horizontally, preferably rotatably, to the handle body on both sides and is designed to be gripped by the person's hand, preferably enclosed. This can make gripping or holding the grip elements more comfortable for the person.

Preferably, the handles are contoured to fit fingers. This can also make gripping or holding the grip elements more comfortable for the person. The hold of the handle elements for the person can also be improved in this way.

The handles preferably have a profiled and/or rubberized surface which increases the friction between the person's fingers and the handles. The hold of the handle elements for the person can also be improved in this way.

According to a further aspect of the invention, the frame box is rectangular and is designed in such a way that the interior space of the frame can accommodate the person horizontally at a substantially even distance. Preferably, the frame box can be square. This can enable a specific implementation of the frame box as already described above.

According to a further aspect of the invention, the frame has a weight receptacle on both sides in the transverse direction for receiving at least one weight, preferably at least one weight plate. This may allow or make it easier to increase or adjust the weight of the deadlift.

According to a further aspect of the invention, the frame has a side bar in the transverse direction between the frame box and the weight holder, which in each case connects one of the weight holders to the frame box in a fixed manner. This can enable a specific implementation of the inclusion of additional weights as already described above.

According to a further aspect of the invention, the frame box and the weight mounts, preferably and the side bars, are designed in one piece as a frame. This can increase the stability of the frame and make it easier for the person to handle.

According to a further aspect of the invention, the frame is made of metal, preferably steel or aluminum. This can increase the stability of the frame.

The above figures are viewed in Cartesian coordinates. A longitudinal direction X, which can also be referred to as depth X or length X, extends. A transverse direction Y, which can also be referred to as width Y, extends perpendicularly to the longitudinal direction X. A vertical direction Z, which can also be referred to as the height Z and corresponds to the direction of gravity, extends perpendicularly both to the longitudinal direction X and to the transverse direction Y. The longitudinal direction X and the transverse direction Y together form the horizontal X, Y, which can also be referred to as the horizontal plane X, Y.

A cross lifting device 1 according to the invention has a frame 10 which can also be referred to as a frame 10 . The frame 10 is designed in one piece, ie integrally, and is made of metal, for example made of steel or aluminum. The frame 10 has a frame box 10a which is rectangular in shape with the longer edges extending in the transverse Y direction. The frame box 10a completely encloses a frame interior 11 in the horizontal X, Y, see for example figure 1 . The four struts (not numbered) of the frame box 10a have a square cross-section.

Centrally in the longitudinal direction X, a cylindrical side rod 10b extends in the transverse direction Y away from the frame box 10a. In the transition region from the frame box 10a to the side rod 10b, a through-opening 10d in the form of a bore 10d through the frame box 10a is provided in the vertical direction. The two side rods 10b each transition into cylindrical weight receptacles 10c, which each have a diameter or a cross section to accommodate commercially available weights 2 in the form of dumbbell plates 2 or weight plates 2. The weight plates 2 can each be pushed onto the weight receptacles 10c and held there by means of known weight retainers 3 in the form of disc retainers 3, as are customary and known for barbells and dumbbells, see for example Figures 3 and 4 .

A handle holder 13 extends through each of the bores 10d of the frame box 10a and is dimensioned to be elongated in the vertical direction Z relative to the frame box 10a such that an external thread 13a of the handle holder 13 protrudes upwards from the bore 10d. The lower end of the handle holder 13 is designed as a rotary handle 13b, which can also be referred to as a knob 13b. The rotary handle 13b can rest against the frame box 10a.

A grip body 12b of a grip element 12 is screwed onto the external thread 13a of the grip holder 13 from above by means of a through opening with an internal thread (not shown). The handle body 12b is arcuate and open at the top. A horizontally extending handle 12a is arranged between the two upper ends of the handle body 12b. The handle 12a is mounted between the ends of the handle body 12b so that it can rotate about its longitudinal axis, which can be done by means of a cylindrical body (not shown) which is arranged fixedly at the two ends of the handle body 12b and which passes through a corresponding through-opening (not shown) in the handle that is subject to play 12a passes through. Each handle 12a is designed to be gripped by a person's hand, see for example figures 2 and 4 . In order to prevent the person's hand from slipping off, the surface of the handle 12a is rubberized.

The person can now use the deadlift device 1 according to the invention to carry out the fitness exercise of deadlifting by pushing the desired weight plates 2 onto both sides of the deadlift device 1 onto its weight receptacles 10c and holding them in place by means of a disc retainer 3 . Prepared in this way, the dead lifting device 1 rests on a floor.

Now the person can enter the frame interior 11 of the cross lifting device 1 from above and crouch down. The person can then orient the two handle members 12 relative to the frame 10 as the person desires. For this purpose, the handle holder 13 can be unscrewed from the handle element 12 to such an extent that the handle elements 12 together with the handle holder 13 can each be rotated freely about their vertical axis. This can only be done to set the desired orientation, so that the handle holder 13 can be firmly screwed to the handle element 12 in the desired orientation of the respective handle element 12 in order to hold the handle element 12 in this orientation in a non-positive manner on the frame box 10a. In this way it can be achieved that the deadlift fitness exercise is carried out with the desired orientation of the respective grip element 12 . Alternatively, the freely movable rotatability of the handle elements 12 together with the handle holder 13 can also be maintained in order to perform the deadlift fitness exercise. In any case, it can be advisable to align the two grip elements 12 slightly inclined inwards towards the person, which can promote the performance of the deadlift fitness exercise.

The person can now grasp the corresponding handle element 12 or its handle 12a with one hand, so that the person stands or squats in the transverse direction Y between the handle elements 12 and in the longitudinal direction X, looking forward and bent over. Then the person can get up from the squat into an upright position and thereby lift the deadlift device 1 together with the weight plates 2 . This allows the deadlift fitness exercise to be performed.

By using the deadlift device 1 according to the invention compared to known barbell bars, it can be avoided that the person can hit the knees or shins on the barbell bar when standing up, as was previously known. Furthermore, the center of gravity of the deadlift device 1 in the longitudinal direction X lies exactly on the center of gravity of the weight plates 2 and the person, so that the fitness exercise of the deadlift can be carried out without straining the person's back.
