Abstract

The invention relates to a retractable physical-training apparatus with pulleys and counterweights for working muscles isotonically. The apparatus has an open door for support. It consists of two parts A and B. The part A is fastened to the top of a door in the open position by clamping the brackets 2 and 7. It has three pulleys 5, 6 and 33. The part B is fastened to the bottom of the door by clamping the brackets 18 and 19 and with the aid of the strap 30, 31. The part B has a single pulley 28. The apparatus according to the invention, which is entirely retractable and does not damage its support, in this instance a door, is intended for working muscles isotonically, for persons not able to attend a gymnasium (fitness centre).

Description

 The present invention relates to an entirely retractable physical training apparatus, to an apartment, to pulleys and counterweights for muscular work in isotonic.

 Isotonic muscular work is that carried out in a physical training room using dumbbells, long or short bars, and polishing and counterweight devices.

 In the physical training rooms, the pulley and counterweight devices are either fixed to the wall using dowels and screws, which makes them removable after use, or placed directly on the ground with a minimum footprint of one square meter. of floor space.

 The device according to the invention is fully retractable and this for the same muscular work. A door is used in the open position as a support for the device.

 The device consists of two separate and unmated parts.

Figure I shows the device fully mounted on its support, an open door (II).

 The first part (A) figure I has three pulleys and is fixed by pinching the door (II) at its top by the brackets (2) and (7). The second part (B) has a single pulley and is fixed to the bottom of the door (II) by pinching the brackets (they) and (I9) had using the strap (30) and (31) Figure 3 and 4.

 The apparatus makes it possible to carry out all the exercises of physical culture usually carried out in physical training room. It is used either in the so-called "High" position using the pulleys (5) and (6) of the cable (34) and counterweight (35), or in position.dite "low" with additional pulleys (33) and (28).

 The part (A), allowing work in the so-called "high" position, consists of a support-in square tube (I) of section 30/24 and 75 centimeters long. On this tube is welded an iron bracket flat (2) of 30 X 5 sec tion.l) years another square of identical section (7) is made an oblong opening (8) allowing the passage of the screws (9) and (IO) whose heads are welded on the square tube (I). This square slides horizontally on the tube (I) thanks to the oblong opening (8) and is pressed against the door (II) - We use the screws (I2) and (I3) in the tapped holes made in the parts (I4) and (I5) welded on the bracket (7), then the nuts (I6) and (I7) are used. The part (A) of the device is then in place by the screws (I2) and (I3) acting only on the metal parts of the device, bracket (2), excluding its support, the door (II) Two other brackets of section 30 X 5 ( 3) and (4) are welded to the end of the square tube support (I) and are used to fix the lugs lees (5) and (6).

The third pulley (33) is fixed in the part (I5).

 The part (B) attaching to the bottom of the door (II) Figures 1,3 and 4 consists of two brackets (I8) and (I9) sliding against each other until pinching the door (II) An oblong opening (23) made in the square (I8) allows the passage of the screws (21) and '(22) whose heads are welded on the square (19). The nuts (24) and (25) tighten the brackets (I8) and (I9) one against the other while pressing each other against the door (II), pinching it. The strap in two parts (30) and (31) as well as the loop joining them (32) hold the assembly against the door (II). A metal plate (20) welded on the bracket (I8) passes under the door (here) prevents the assembly from going up in certain exercises The pulley (28) is fixed to the bracket (I8) by means of two other brackets (26) and (27 welded to each other and (26) welded to (I8).

 For exercises in the so-called "high" position, only the pulleys (5) and (6) are essential. For the exercises in the so-called "low" position, the pulleys (28) and (33) come into action, the latter being fixed on the part (I5).

 The device according to the invention is particularly intended for people who cannot go to a physical training room and who wish to work their muscles in åo O4Qii only.

 The device according to the invention is easily assembled and disassembled without any deterioration by a single person.
