[0070] In particular, said plates (1 ) are also provided with a semi-curved lateral slot (2) which constitutes the sliding cone system; nine transpassed holes (3) equidistant of 18mm in diameter, arranged on the back of said plates (1 ) intendedto accommodate nine transverse bars (4) equidistant of 100mm in length and 25mm in diameter; two fillets of EVA rubber (5) in rectangular format, one accommodated at the upper end (6) and the other at the lower end (7) of its inner face (8), given greater adherence and stability of the device to the side faces of the door (103).

[0071] Said semi-curved side slot (2) has at its upper end a domed diameter reduction (9) dedicated to the perfect fit and coupling of the portable device (100) in the door handle (102) (103).

[0072] Preferably, the slots (2) are arranged on the front of the plates (1 ) so that when coupling the device (100) to the handle (102) of the door (103) the transverse bars (4) are arranged on the back of the aforementioned plate (2) rest against the front face of the door (103) to provide the device (100) with total stability both horizontally and vertically.

[0073] In one of the modalities of the device (100) the transverse bars (4) are solid and when passing through the holes (3) the fixation plates (1 ) are welded, extending for 70mm on each side.

[0074] In one of the modalities of the apparatus (100) the crossbars (4) consist of three detachable parts, the first being characterized by a central bushing (10) equipped with internal threads (1 1 ) at both ends (12), the second and third characterized by pins (13) provided with an external thread (14) at their internal ends (15).

[0075] In the modality where the transverse bars (4) are made up of parts (1 1 / 13), the anchoring and locking of the same in the fixation plates (1 ) is carried out by an opposite threading system.

[0076] In both of the aforementioned modalities, the transverse bars (4) extend for 70mm on each side of the fixation plates (1 ) at intervals of 100mm along the vertical axis, to attach resistance exercise products, such as elastic bands (101 ) and others.

[0077] The locking system of the aforementioned device (100) to the door (103) is characterized by the fact that the central crossbar (16) rests under the retractable latch (104) of the door (103) which in turn prevents the uncoupling the device while performing any exercises.
