2 Claims. (Cl. 12S-24.1)

This invention relates to stroking-massage apparatus.

There are already known some apparatus for stroking massage in which, in a casing, a heating resistancee. g. a filament-lamp (incandescent lamp)-is placed behind a cap or lens, consisting of a material permeable to light and heat, the position of which can be adjusted in relation to this lamp. Massage is effected with these apparatus by holding the casing and stroking with its cap or lens the part of the body to be treated.

In the case of the stroking-massage apparatus forming the object of this invention an improvement of these, already known types is achieved by screwing the cap, designed preferably as a convexe-concave lens with its concave side turned outward, on a detachable jacket made of a heat-retaining material, favorably of asbestos-Bakelite.

The casing may likewise be made of asbestos-Bakelite, in which case the casing should be constructed so as to consist of two parts.

By this construction of the casing the energy emitted by the lament lamp undergoes a directing effect whereby, on the one hand, radial emission of energy is prevented by the heat-retaining jacket and, on the other hand, a concentration of the emitted light and heat rays is achieved by the lens-like form of the cap. The concave outside face of the cap provides, at the same time, the sucking action which is of beneficial effect for the massage.

A further object of the invention consists of making the cap of synthetic resin, preferably methyhnethacrylate :also known as Plexiglas (safety glass, toughened glass) of blue color.

The surfaces of the concave side of the lens may show various radii of curvature. The edge of the hood may be bulged in order to enable treatment of cavities in the surface of the human body. A groove may also be machined into the inner surface of the hood for puttying.

According to the invention provision has been made to unite the cap or lens with the jacket intoone single piece by means of a warm pressing process.

The directive eiect brought about by the use of a casing of asbestos-Bakelite can still further be agumented by providing the sides of the lament lamp bulb with a metallic coating, preferably on the inside, silver being particularly suitable for this purpose.

The jacket bearing the cap may be fastened to the casing, in the way of a bayonet fastening, by means of a pin gliding in an angular slot.

Preferably the bottom of the casing bearing the lament-lamp, is, according to the invention, pierced through by an opening running parallel to the sockets for the insertion of the contact plugs of the lament-lamp; into this opening a pin or the like is inserted which allows the lament-lamp to be adjusted within the casing or to be removed from it.

The socket of the lamp may be provided with a separating rib reaching through between the sockets serving for the insertion of the contact plugs, and preventing both sparking over and inserting the lamp too deeply.

These and other characteristics of the subject matter of the invention come forth from the drawings which illustrate by way of examples three constructional forms thereof, Figs. l and 2 show axial sections of the rst constructional form, on planes perpendicular to one another. Fig. 3 is a top view of Fig. l, with the lamp, jacket and hood removed. Figs. 4 and 5 visualize the plug associated with the apparatus, in two axial sections perpendicular to one another. Fig. 6 is a top view of Fig. 4, with the casing removed. Axial sections of the second and third constructional forms are shown in Figs. 7 and 8, respectively. Fig. 9 is a schematic diagram of a switchbox fitted in the cord.

According to the rst constructional form the casing 1 consisting of Bakelite or the like preferably of blue colour bears at its base a socket 2 into which the plug-sockets 3 and 4 are pressed; they are separated spark-proof by a rib 2a of the base-socket. In between them and the screwed plug-sockets 5 and 6 .which are inserted into them

contact blades

7 and 8 are clamped; the leads-in 9 and 10 of a cable 11 which leave the casing through the ring 12 are connected to these contact blades.

The

plugs

13, 14 of the holder 15 of a filament lamp 16 are inserted into the sockets 3, 4 or into the screwed sockets 5, 6 until the lamp rests on the insulating rib 2a.

The base of the casing is pierced within this rib by an axial opening (or bore) 17.

The ilament lamp is surrounded by a jacket 18; this jacket has an angular slot 19 catching with the pin 20 of the casing.

The jacket 18 has at its outer end a screw-thread 21 serving for the screwing on of a cap 22 of blue synthetic resin, also known as Plexiglass, or the like. By an outer, concave face 23 and an inner, somewhat more bent face 24 the front of this cap is shaped in the way of a convexoconcave lens. Each face of the lens has varying radii of curvature. Between casingl and jacket 18 or cap 22 is placed a packing ring 25.

The jacket together with the cap may easily be connected to the casing or separated therefrom by means of the bayonet-lock-like fastening consisting of the slot 19 and the pin 20.

The filament-lamp may be easily shifted within the casing or removed from it by inserting from without a pin, a knitting needle or the like into the opening 17 and shifting or removing thereby the lamp.

By screwing the cap 22 on the jacket 18 a focal adjustment of the lens consisting of the

faces

23 and 24 is made possible; thereby the apparatus may be used either as a point-irradiating device for deep-treatment, or as a surface-irradiating device with a greater dispersive action.

It is preferable to make the thermic jacket 13 of asbestos-Bakelite which will screen olf heat emission in a radial direction.

With the second constructional form the edge 48 of the hood 47 is provided with a bulge which enables treatment of cavities in the surface of the body. A groove 49 is provided inside the hood for puttying 50. The side walls of the lament lamp 51 are coated with silver, on the inside of the bulb, which prevents radiation of energy toward the sides.

According to the third constructional form the casing consists of a bottom part 53 and top part 54, the latter is in the form of a jacket made of asbestos Bakelite. This jacket is screwed to part 53 by means of a screw thread 55. The hood 56 is screwed to the jacket 54, and may also be secured in place by spreading a layer of putty 50 (see Fig. 8, at right). When

parts

54 and 56 are unscrewed together from the base 53, the lament lamp 51 may readily be removed.

The plug which is to be used preferably for the strokingmassage apparatus according to the invention consists of a base plate 26 made of Bakelite or the like into which the

pins

27 and 28 are pressed in. Their back

square end

29 and 30 have axial thread-bores into which the fastening-screws 31 for the casing 32 can be screwed. In ordei to prevent the fingers of the person operating the plug from touching the screws 31 the hollows of the casing 32 which .accommodate the screw-heads are Vclosed lby screwed-in plugs 33 made of an insulating material.

The cable 11 with the lines 9 and 16 enters the casing through the ring 34. The line 9 is connected to a contact blade 35 which is assembled with the square 29 by the screw 36. The line 10 is in connection with a small plate 37 clamped between two nuts 33 of a bolt 39; this bolt and also the

pins

27 and 28 are pressed into the base plate.

The switch lever 40 can be turned round the pin 39. A contact blade 41 and the projection of a socket of the resistance 43 are fastened to the square 30 with a screw. The other socket 45 of the resistance is connected with the small plate 37 by means of a wire connection 46.

In the position of the lever 40 which is drawn with full lines in Fig. 6 the electrical current entering for instance through the pin 28 takes its way through the resistance 43 into the line it) while, when the lever is turned into the position as shown in Fig. 6 by dot-and dash lines, the lever touches the contact plate 4l and the resistance 43 is short-circuited. Fig. 5 shows the lever 4) in its middle position.

Instead of placing the switch in the plug, a switchcasing 61 with lever 52 can be mounted in the

cable

59, 60 leading from the plug 57 to the filament-lamp 58 (Fig. 9). By turning the same the switch 63 is either in open or closed position. When the switch is opened the current iows over the resistance 64, so that the lamp 58 then lights with reduced tension.

Normally the stroking-massage apparatus is used with short-circuitcd resistance and then the filament-lamp produces, as an example, ten lux. When that temperature is reached which gives the body the most pleasant feeling the resistance 43 is switched in whereupon the current will only compensate the radiation losses and the temperature will remain constant.

By suitably adjusting the form and the dimensions of the apparatus it can be used also for all cavities of the body, e. g. throat, ears, intestine, urinary passage, and female cavities. In this cases it will generally be necessary to build in a still greater resistance than for the treatment of the surface of the body.

If three sockets are provided instead of two the apparatus according to the invention may be tted with a lamp giving light at option with two different outputs (Bilux lamp).
