DE2437053A1 - Vibrating massage device with large axial movement - has internal coil-up system and compression spring tensioned by this process - Google Patents

Abstract

A massaging device with axial vibration direction is constructed to allow length axial movements and has its inner diameter smaller than the length of axial motion produced. The axial motion is produced by the coiling up of a traction cable on a blade rim or by means of the action of a gearwheel on a gear rack. The extent of the motion is given by d PI. Coil up of the traction cable tensions a compression spring which is mounted within the housing and which is released by a device which senses when the cable has been fully coiled, and allows the compression spring to force the end of the massage device outwards. This process is repeated rapidly.

Description

Re: Axial massage stick It is used for body massages of all kinds mechanical aids used The most common ones are hand-held massagers with vibration effect.

The visual vibrations with high frequencies are electromagnetic Way or by a radial imbalance of an eccentric on the motor shaft (Shaker effect) The well-known massage devices only have short-stroke Vibrations0 The need for a long-stroke massage device, which is axially Direction works, could not be covered so far. Developed for this reason I use the "Achsial-Eassagestab" and make a patent claim on it.

Description: The axial massage stick according to the accompanying drawing shown, achieves the following performance due to its construction The housing, which is made of lightweight plastic houses a inside mechanical transmission, which is coupled to a weak drum motor.

This gear is built into the housing with guide rollers in such a way that that it can slide back and forth 60 - 70 mm.

The resulting stroke of approx. 60 - 70 mm takes place in the axial direction and caused by the mass persistence of the relatively heavy gear - in proportion for a light outer shell - an axial impact effect.

The function of the gearbox which enables it with an inside diameter of the housing of approx. 30 mm to generate a stroke of 70 mm is described below Hand of the drawing Figs. 1, 2 and 3 explained and described.

The housing (a) is made of plastic and weighs only a few grams.

Guide grooves and 2 built-in busbars are built into the housing (b).

In this housing there is a mounted on guide rollers (d) Low-voltage motor (c).

The power supply for this motor is obtained via the power supply line (1) as well as the pantograph (s) In front of the engine is a worm and gear transmission (f), which has the function of revolving up to approx. loo To reduce RPM and to increase the pulling force accordingly.

Next to the front gear wheel is a roller with built-in Coupling (h) o On this roller there is a tread (g) The tread (g) has a diameter of approx. 25 mm and the task of a pull rope (i), which on one side on the running ring (g) and on the other side on the housing (a) Unwind the rope fastening eyelet (k) with a partial turn.

While the pull rope is being wound up by the running ring (g), it moves the gearbox and the motor in the direction of the front part of the housing.

A compression spring (J) is located between the housing and the gearbox is compressed and tensioned during this process.

When the tread has completed a partial revolution, it becomes more specific Disengage the coupling (h) so that the running ring is on the roller can move freely.

The cocked peder (j) then pushes the engine and transmission back in the rear part of the housing back until the pull rope (i) is taut.

At this point the clutch (h) re-engages the running ring and repeats this process, which continues until the engine switches off will.

Through the function of the tensioned peder and the pushing apart The following effect is caused by the gear and housing by approx. 60 - 70 mm: Motor and gears have 4 - 5 times the weight of the housing.

By winding up a pull rope or similar object a wheel, this is 3.14 times the wheel diameter. Instead of a tread and rope can also be a gear and a rack with the same importance Find use.

The winding takes place continuously and evenly.

After releasing the clutch, however, the tensioned compression spring pushes both of them Parts apart. Since the motor and gearbox are 4 - 5 times the weight, move According to the law of inertia, they differ less from theirs due to the inertia of the masses Space than the case, which is only 1/5 of the aforementioned weight. Consequently the housing exerts a movement in the axial direction.

The thrust generated by this massage device is different from the previous massage devices.

This is the value of the invention.

Attachment devices can be used for various types of massage which, however, do not contribute to the meaning of the actual invention.

The characteristic of the device of the axial shock movement also enables use in the building trade.

By tapping it non-destructively, it is used for acoustic detection of concealed plumbing, heating, ventilation and electrical installation lines.

Claims (1)

PATENT CLAIM Massage stick acting in the axial direction, characterized by that this device makes it possible to carry out axially directed impacts in long strokes. The inside diameter is smaller than the executed stroke. The lift is created by winding a traction rope onto a running ring or transferring a gear to a rack. The stroke is calculated from: d x pi When the pull rope is wound up, a compression spring is tensioned, which is located between the gear and the movable housing is located. After a partial rotation, a clutch interrupts the clamping process, so that the spring abruptly pushes the housing back into its starting position. After completing a full turn, the clutch engages automatically and the process described above begins again. According to the law of inertia, the 4 - 5 times heavier gear remains in the same proportion as the lighter case. The consequence is this movement derived outward via the lighter housing, which actually p Identifies the purpose of the invention. 7th
