Description of the Invention

APPROACH TO THE PROBLEM: This involves designing an automatic back massager, particularly for the cervical and lumbar areas, which is easy to use and does not require the help of other people, given how difficult it is for a single person to massage their back. .

ADOPTED SOLUTION: The structure of the apparatus is basically composed of the sheath (3), the telescopic tubes (3.1), the connecting rod (6) - crank (7), and the casing (2), which houses the motor assembly (4 ), the pinion (4.3), and the sprocket (5).

Inside the box-shaped casing (2), made of plastic or aluminum, there is an electric motor (4) equipped with a frequency variator (4.1), which allows its rotation speed to be varied. Said motor (4) operates by means of a pinion (4.3), a toothed wheel (5) that by means of a connecting rod (6) - crank (7) mechanism transforms the rotary movement into a longitudinal movement.

The crank (7) moves vertically inside the guide (8) and has coupled at its upper part to a massage head (9), which is articulated by its central part on the axis of the head (9.2), and by its free end on the bolt (9.1) together with said crank (7). On the other hand, the crank (7) is articulated with the connecting rod (6) by means of the screw (7.1) whose butterfly-type nut (7.2), allows to disassemble the massager apparatus (1) and fold it.

The massage head (9) is easily removable, making it easy to use one, several, or change their position. As seen in Figure 1, up to three massage heads can be placed, or only one can be placed on any of the three head axes (9.2).

Due to the curvature of the back, the massage heads (9) have an extendable tube (9.4) that together with the spring (9.3), allow the massage ball (9.5) to adapt its position to the contour of the back of the user.

Furthermore, the apparatus allows folding by inserting the telescopic tube (3.1) into the sleeve (3), and for this it has buttons (3.2) that allow the telescopic tube (3.1) to be fixed in a certain position; either folded or fully or partially unfolded.

These characteristics make it easier for people of different sizes to use the massager apparatus (1).

The person using the massager (1), once the position of the heads (9) has been adjusted, must fix it to the back as if it were a backpack using the lower (11) and upper (12) harnesses.

The cushion (10) with its respective padding, makes it easier for the user to adjust to the massager apparatus (1), resting it on the lower part of the waist.

Finally, by means of the potentiometer (4.2), the motor (4) can be switched on or off and its rotation speed can also be regulated.

TECHNICAL CHARACTERISTICS: The back massager apparatus (1) is basically composed of two telescopic tubes (3.1), joined by a traverse (3.3) at its upper end. Said tubes slide along respective guides (3) which are embedded in their lower part, in the casing (2).

Parallel to the plane defined by the telescopic tubes (3), and at a distance of about 10 cm, there is a connecting rod (6) - crank (7) mechanism, arranged vertically, whose crank (7) slides inside the guide (8 ), which is linked to the telescopic tubes (3) by the fins (8.1).

Said connecting rod mechanism (6) - crank (7), is driven by the set consisting of an electric motor (4), a pinion (4.3) and a gear wheel (5). This set is arranged inside the casing (2).

At the upper end of the telescopic tubes (3.1), there are three horizontal equidistant axes (9.2), arranged in a vertical plane, on which the massage heads (9) pivot, which are articulated by their free end on the bolts ( 9.1) together with the handle (7), which when sliding vertically causes the circular movement of the massage balls (9.5).

The massage heads (9) have an extensible tube (9.4), retractable, by action of the spring (9.3).

The connecting rod (6) and the crank (7) are linked by means of a screw (7.1) and a wing nut (7.2).

The position of the telescopic tubes (3.1) and the crank (7) is determined by means of the retractable buttons (3.2) and the screw (7.1) placed in one of the holes (7.3), and therefore the height of the telescopic tube (7).

The toothed measure (5) rotates on the wheel axle (5.1), which is fixed to the inner walls of the casing (2).

The motor rotation speed (4) is controlled by the frequency variator (4.1) and the potentiometer (4.2).

On the front of the casing (2), there is a cushion (10), padded, with a rectangular shape. The set is completed with a lower harness (11) arranged on both sides of the housing and the upper harness (12), on the crossbar (3.3).

The housing is ABS plastic.

The metal tubes are aluminum.

The motor (4) of alternating current and 220 V, has an estimated power of 250 W. Its weight must be less than 1.5 Kg.

ADVANTAGE:

- The device performs an effective massage on the entire back, relieving any contracture.

- Allows the speed of the massage head to be varied by simply turning the motor potentiometer.

- You can place one, two or three heads, or place one head in any of the three positions.

- The massage balls can be changed to suit the user.

These can be both rigid and padded, and their surface can be smooth, rough, with frusto-conical spikes etc.

- The device is foldable, allowing it to be stored and transported easily.

ACRONYMS USED:

ABS: Acrylonitrile Butadiene Styrene.

V: Volt.

W: Watt.

Kg .: Kilogram.
