Description

The present invention relates to a connection concept for platforms and handles in exercise equipment, in particular vibration exercise equipment.

Vibration training devices have become increasingly popular in recent years, as they can be used for sports exercises such as push-ups, and the vibration, which is transmitted from the vibration training device to the user via the handles, can further increase muscle stimulation, creating a increased fat burning and improved muscle building can be achieved.

Until recently, vibration training equipment was only available in professional sports facilities such as gyms, but recently it has become more and more compact and can therefore also be used at home.

In the state of the art is the document DE 20 2020 102 479 U1 known, which includes a connector with a socket and a plug.
The bushing includes a recess in the bottom surface of which a locating pin is provided.
Furthermore, at least one groove is provided on the inner lateral surface of the depression or on the outer lateral surface of the positioning mandrel. The corresponding connector includes a base plate to which a hollow body is connected. The hollow body is intended to be inserted into the recess of the socket, with the outer lateral surface of the hollow body lying against the inner lateral surface of the recess and the inner lateral surface of the hollow body being in engagement with the positioning mandrel. At least one connecting element is provided on the hollow body, and the depression of the socket comprises one or more grooves. In the mated condition, the connecting element of the plug is adapted to engage a complementarily shaped groove of the socket, and the inner surface of the hollow body is adapted to engage the locating pin of the socket.

Also from the state of the art is the document DE 20 2017 004 115 U1 known, in which a vibration training device is disclosed. At this
Vibration training device training handles are disclosed in particular, which can be attached to an upper plate or housing part of the vibration training device. For this purpose, holding devices are provided in the surface of the vibration training device, which are designed as recesses, and the handles have complementary fastening devices that are designed in such a way that the handles can be used firmly for safe use of the vibration training device, but can still be used in the recess.
In this vibration training device, a handle has two feet which can be inserted into a pair of corresponding recesses on the surface of the vibration training device. It is also disclosed that there are various recesses on the surface of the vibration training device, and the handles can be inserted into two associated recesses for different applications.

Also known in the prior art is a platform for push-ups with different hand positions, which is shown in document CA 2,873,493.
Various embodiments are disclosed in this document, here too there are plug-in handles which can be plugged into a combination of two holes with two feet. There are different combinations of holes on the surface of the training platform, so that plug-in handles can be inserted parallel to the short side, parallel to the long side or at an angle. Various areas of application are revealed on the surface of the vibration training device, which are transferred to the hole combinations with color codes - for example, suggested plug-in grip positions for training the shoulders, chest, triceps and back.
As a further embodiment, document CA 2 873 493 also discloses the possibility that the handles have only one foot, which in this case is polygonal, ie hexagonal. In this case, it is enough to insert a foot into a hole on the surface of the vibration training device.
However, this solution is not necessarily safe, since one plug-in handle can easily fall out of the hole or be lifted out of it by vibrations. This possibility harbors a certain risk of injury, since the handle can easily slip out during an exercise due to tensile forces and the user could thus injure himself.

It is therefore the object of the present invention to provide a connecting device, for example for the surface of a vibrating board and plug-in handles, which eliminates the disadvantages mentioned above and which enables a firm and secure, but nevertheless detachable connection between the handle and the vibrating board. in which multiple positions and positions of a plug-in handle are easily possible, and whose production is simple, efficient and inexpensive.

This object is achieved by a plug connection according to claim 1 and by a training platform according to claim 21. Further advantageous configurations are the subject matter of the dependent claims.

A plug connection according to the invention comprises a socket and a plug. The bush comprises a recess in the center of which a fixing device is provided. The fixing device preferably sits on the bottom of the recess or is attached to it. Furthermore, the indentation comprises a groove which is provided in an inner lateral surface of the indentation or on an outer lateral surface of the fixing device. The plug includes a base plate to which a hollow body is attached, on which at least one feather key is provided. The cavity of the socket is adapted to receive the hollow body of the plug. When mated, the at least one key of the plug is adapted to engage a respective complementary shaped groove of the socket or recess, and at least a portion of the hollow body is adapted to engage at least a portion of the fixture or touching the fuser. If the groove is provided on the inner lateral surface of the recess, the at least one feather key is provided on the outer lateral surface of the hollow body. If the groove is provided on an outer lateral surface of the fixing device, the at least one feather key is provided on the inner lateral surface of the hollow body.

A plug connection designed in this way enables a plug and a socket to be securely connected so that the connection can withstand greater forces without loosening, namely both tensile forces and torsional forces. At the same time, however, it is possible for a plug to be pulled out of the socket again and for a person with the appropriate strength to separate the socket and plug.

The groove is preferably provided on the inner lateral surface of the recess, and the at least one feather key is provided on the outer lateral surface of the hollow body. In the state in which the hollow body is inserted into the recess, the fixing device then presses the hollow body and the feather key outwards, so that the latter is pressed into the groove. This type of connection has an advantageous stability.

The at least one groove preferably extends downwards from the upper edge of the indentation to at least the middle of the height of the indentation, preferably up to a maximum of 70° of the height of the indentation. The groove thus extends from the top edge of the recess into the recess towards the bottom of the recess.

This makes it possible that the groove does not have to be formed over the entire height of the recess, which leads to increased stability - at the same time the plug, which is plugged into the socket, is still secured against torsion.

The fixing device preferably extends upwards from the bottom of the depression to at least the middle of the height of the depression, preferably up to a maximum of 70% of the height of the depression. As a result, the fixing device does not reach all the way to the surface or upper edge of the depression, which allows the plug to be inserted more easily into the socket. Top in this case means the top of the well, which is the opposite side from the bottom of the well.

The fixing device is preferably provided in the form of a cylinder, a truncated cone or a cone. Preferably, the inside of the hollow body is also provided correspondingly cylindrical, truncated cone-shaped or conical. As a result, the inside of the hollow body is preferably formed in each case in a complementary manner to the fixing device.

The fixing device preferably has a recess on its upper face, which is preferably designed in the form of a bore. As a result, dirt such as dust entering the recess would not impair the stability of the connection between plug and socket.

More preferably, a plurality of grooves are provided on the recess - this protects a plug in the socket even better against torsion, i.e. a plug cannot rotate when it is plugged into the socket. If several, for example two, feather keys are also provided on the hollow body, several feather keys absorb any torsional forces; this reduces the risk of a feather key breaking.

An even number of grooves is preferably provided on the recess, which can be, for example, two or eight grooves.

It has been found that such a number of grooves is optimal for the application of connecting a connector to an exercise machine and further for production. If two feather keys are provided on the hollow body, a socket with two grooves would have one plug-in position, a socket with eight grooves would have four plug-in positions - with such a socket, the plug with the handle for a training device in the different Positions can be plugged in, whereby several different muscle groups can be trained.

The fixing device preferably has a first section, which is provided at the bottom of the recess, and a second section, which is placed on the first section. The two-part configuration of the fixing device results in advantages in terms of manufacturing technology, since a second section can be manufactured separately and attached later. Furthermore, if the second section breaks, it can be easily replaced without having to replace the entire training device.

The second section of the fixing device preferably has a recess on its upper side.

More preferably, the first portion and the second portion of the fixation device are connected to each other by a fastener - this can be easily assembled, and the second portion of the fixation device can be manufactured separately, for example by injection molding.

More preferably, the fastener is a screw - a screw is a very simple form of fastener and is also inexpensive.

Preferably, the second portion of the fixing device has a pressing portion adapted to press against the inside of the hollow body when the hollow body is inserted into the recess. The pressing section can also be prestressed so that it presses against the inside of the hollow body and thus fixes the hollow body in the recess (and possibly the at least one key in a complementary groove).

More preferably, the hollow body comprises a first section, and in the lower region of the hollow body, more preferably, an annular cap is used, on the end face of which at least one recess is optionally provided.

The pressing portion of the fixing device is then adapted to press against the inside of the cap when the hollow body is inserted into the recess - this is a very simple and safe way of fixing the plug in the socket, which also keeps it stable. The cap is, so to speak, a smaller hollow body (with a correspondingly smaller diameter) which is provided concentrically in the actual hollow body.

In a further embodiment, the second section of the fixing device preferably has at least one fixing tab on the side, which protrudes from the fixing device and extends downward in the direction of the bottom of the recess.

More preferably, this extends obliquely downwards in the direction of the bottom of the depression, even more preferably, a plurality of fixing tabs are provided on the fixing device, more preferably an even number of fixing tabs.

The at least one fixing tab is used to better fix the hollow body in the depression.

The hollow body further preferably has a first section and, on its lower region, a projection which extends toward the central axis of the hollow body. This projection is adapted to engage (preferably prestressed) with the at least one fixing tab of the fixing device when the hollow body is inserted into the recess. By having the projection engage a locating tab, the plug is held securely in the socket, but at the same time is somewhat flexible and thus bendable, and this still allows the plug to be removed from the recess by the application of suitable forces.

A training platform according to the invention has a plate or surface on which one or more plug-in connection(s) according to the present invention are provided, with one or more sockets then being integrated into the surface. These bushings can contain a different number of grooves. Furthermore, the training platform comprises at least one plug-in handle, which has a plug, and the plug-in handle with the plug is preferably adapted to be plugged into the at least one socket.

More preferably, individual or all grooves of the sockets are marked in color. This allows a user to more easily insert and position the plug-in handles for specific exercises.

More preferably, the training platform is designed as a vibration training device. Especially with such a vibration training device, it is important that plug-in handles with plugs are held securely in corresponding sockets without this connection being able to be loosened by vibrations.
