Description

Massager

The invention relates to a massage device with a massage head and a handle that can be attached to it.

The invention has for its object to provide a universal massage device. This object is achieved by the massage device described in claim 1, which on the one hand has two opposite, different surface-profiled treatment surfaces and, on the other hand, an insertion shaft arranged between the treatment surfaces for the insertion end of a handle, which is connected to the massage head via a detachable snap connection. This embodiment allows the massage head to be used with or without a handle, the different treatment surfaces, with their design, making different massage variants possible.

Basically, all releasable snap connections known from the prior art can be used, but preferably the snap connection described according to claims 2 or 3 is used. In the first case, the massage head has an insertion shaft for an insertion end of the stem, which, with an elastic tongue, forms a locking shoulder for engaging behind a shaft-side counter-locking, which can be released by actuating a release pin, the release pin end projecting outward into the treatment area corresponding to the surface profile of the treatment area is modeled.

As an alternative to this, it is also possible to design the insertion shaft to be continuous in the massage head, so that the shaft forms an opening which completely penetrates the massage head. The insertion end of the handle also has an elastic tongue to form a locking shoulder, which engages behind the outer surface of the massage head when connected. This embodiment has advantages in terms of production technology, since a trigger pin and its storage in the Massage head can be dispensed with. The resilient tongue of the insertion end can be pressed together to release the stem and pushed in the direction of the insertion shaft, after which the insertion end of the stem can be pulled out. The counter detent can be formed by the outer circumferential surface of the massage head in the vicinity of the insertion end or in that a shoulder shaped shoulder is excluded shortly before the respective insertion shaft end, which then forms a counter detent surface. In any case, the end of the resilient tongue which projects out of the massage head when the handle is connected to the massage head must be able to be compressed manually to such an extent that the latching connection is released.

As a result of such a configuration, a massage device of the type in question with increased utility value is specified. The opposite, different surface-profiled treatment areas can be used with or without a handle. If the stick is in the shaft, it can only be removed from the massager with emphasis on the will, by actuating the elastic tongue or the relevant release pin, the release pin end of which protrudes into the treatment area and fulfills a double function: on the one hand, it is used by a finger to to bring the locking shoulder of the elastic tongue in question out of engagement with the shaft-side counter-locking. Only then can the handle be removed. On the other hand, the release pin end represents a section of the surface-profiled treatment area with unrestricted use of this treatment area during a massage.

An advantageous further development can be seen in the fact that the release pin end is dome-shaped and the treatment surface has a large number of similarly shaped domes. In order to distinguish the release pin end from the domes, for example, the outline of the release pin end can be smaller or larger than that of the domes. There is also a color distinction between the domes and the release donating possible. The domes themselves can be sections of rotatably mounted balls with the result of superimposed rolling and static friction during a massage. The assembly of the stem and massage head is facilitated by two symmetrically designed, fork-shaped tongues. It is therefore not necessary to pay attention to a specific insertion position of the handle. It is also possible to use a cranked handle so that it has the most favorable arrangement with respect to the massage head with regard to the treatment area used. The latter can be round or elliptical in plan. A polygonal shape would also be conceivable. Then the one treatment surface of the massage head can be the surface of a stone or a technical ceramic with non-abrasive smooth-wave micro-profiling that resembles orange peel. This can be produced in such a way that the rough surface of the stone or the technical ceramic is covered with glass dust and then heated, so that this orange-skin-like surface contour subsequently results.

As an alternative to the embodiment described above, a treatment surface can also consist of a plastic body with a rough, preferably elastic surface. The plastic body or at least its surface forming the treatment surface preferably consists of an elastomer (rubber).

Then it should be emphasized that the stone, the ceramic or the plastic body is framed by the massage head. This gives him a safe embedding. If the massage head is used without a handle, it proves advantageous to provide fastening buttons for a handle on the circumferential surface. The latter can therefore be assigned to the massage head so that either one or the other treatment area is used. Another advantageous embodiment is that one wall of the shaft is formed by a track bearing plate for the balls. The track bearing plate ensures that the balls protrude with their ball sections by the predetermined amount. This track bearing plate is then still used to form the shaft-side counter-latch. So that the trigger pin or its trigger pin end only protrudes beyond the massage head to a certain extent, the trigger pin has a collar that can be moved in a chamber with limited stops. When the handle is inserted, the resilient tongue acts on the release pin in such a way that the collar enters the chamber floor in the stop position. The trigger pin is acted upon by the end of the tongue. The ends of the tongues are otherwise designed so that they form insertion bevels. This allows the handle to be inserted easily into the shaft, the tongues inevitably deflecting. When the insert end position is reached, the tongue facing the track bearing plate can then act with its locking shoulder to counteract the track position, capturing the handle in its inserted position.

An embodiment of the invention is explained below with reference to the drawings. It shows

Fig. 5 is an illustration like Fig. 3, but with the trigger pin pressed and thereby released rest between the handle and massage head and Fig. 6 shows the massage head with the handle inserted in the inverted position.

The massage device designated as a whole by the number 1 has a massage head 2 and a stem 3 which can be fastened thereon. In the exemplary embodiment, an elliptical plan of the massage head 2 is selected such that the stem 3 extends in the extension of the longer axis of the ellipse.

The massage head 2 has a two-part, plugged-together housing, consisting of the housing parts 4 and 5. These can consist of a suitable plastic. The housing part 4 is provided with a stepped projection 6 which is elliptical in plan and which is enclosed in a form-fitting manner by a peripheral outer edge 7 of the housing part 5. A track bearing plate 8 lies flat on the projection 6 and is accordingly also gripped by the outer edge 7. Balls 9 rest on the side of the bearing plate 8 facing away from the projection 6. These are provided on the massage head 2 in a distributed manner and protrude beyond the outer broad surface with corresponding dome-like sections 9 ', which form a treatment surface B1. The balls 9 themselves are rotatably seated in bores 11 which are open towards the thrust bearing plate 8 and which taper in the direction of the wide surface 10, so that the balls 9 cannot fall out of the bores 11.

At the edge of the housing part 4, an insertion shaft 12 lying in the longitudinal axis of the ellipse has a rectangular cross section such that one shaft wall 12 'is formed by the track bearing plate 8. The stepped insertion end 13 of the handle 3 'provided with an offset 3' can be inserted into the insertion shaft 12. In particular, the insertion end 13 has two symmetrically designed, fork-shaped tongues 14, 15. Material with spring properties is selected for the handle 3, so that the tongues 14, 15 also have spring properties. Each tongue 14, 15 forms a locking shoulder 16 extending transversely to the direction of insertion. The two locking shoulders 16 are arranged at the ends of the tongues 14, 15 insertion bevels 17. Both run at an acute angle to one another such that when the handle 3 is pulled off, the smallest distance between the insertion bevels 17 is smaller than the width of the insertion shaft 12. In the area of the greatest width of the insertion bevels 17 there are the locking shoulders 16. There, the width of the insertion bevels 17 is greater than the width of the insertion shaft 12. Accordingly, the resilient tongues 14, 15 are moved against each other when the insertion end 13 is inserted into the insertion shaft 12. The free end of the locking shoulder 16 of one tongue 14 or 15 is supported on the shaft wall 12 ″ opposite the bearing plate 8. There is no locking there. The latching takes place on the tongue facing the track bearing plate 8 in such a way that the latching shoulder 16 engages behind a counter latch 18. This is formed by a recess 19 of the track bearing plate 8 and accordingly corresponds to the shaft wall 8 '. This means that in the inserted end position of the handle 3, the latching shoulder 16 of the tongue 14, 15 facing the track bearing plate 8, due to the resilient provision of this tongue, engages in counter-engagement 18.

At the level of the recess 19, the track bearing plate 8 has a bearing bore 20 for a release pin 21. The same is equipped with a collar 22 which can be moved in a chamber 23 of circular cross section of the housing part 5 with limited stops. When the insertion end 13 is inserted into the insertion shaft 12, the insertion bevel 17 of the tongue 14, 15 facing the track bearing plate 8 acts on the inner end of the release pin 21 and displaces it in the outward direction. The outward movement is limited by the chamber bottom in cooperation with the collar 22. In this position, the trigger pin end 25 guided in a bore 24 of the housing part 5 projects beyond the wide surface 10. The trigger pin end 25 there forms a dome 25 '. This lies at the same level as the spherical sections 9 and is therefore the surface profile of the treatment surface B1 modeled. In this outwardly displaced position, the trigger pin 21 is supported by the insertion bevel 17 of the tongue 14 or 15 facing the track bearing plate 8.

The insertion shaft 12 can also be designed as a penetration penetrating the entire massage head, so that there are two insertion openings on opposite sides of the massage head. In this case, the insertion shaft 12 is designed without a counter-catch 18. The insertion end 13 has a length which is greater than the length of the insertion shaft, so that the locking shoulder 16 of the resilient tongues 14, 15 protrudes from the insertion shaft in the connected state and the outer lateral surface of the massage head forms the counter-locking around the insertion opening. In this embodiment, the parts of the resilient tongue can be pressed together with the thumb and forefinger and inserted into the insertion shaft 12, after which the insertion end of the handle can be pulled out completely. Within the scope of the present invention, such embodiments are also detected in which the counter-catch 18 is provided at the end of a continuous opening 12, the ends of the elastic tongues projecting out of the massage head in the connected state to such an extent that they can still be actuated to release the catch connection.

The housing part 4 forms on its outer broad side an elliptical embedment trough 26 while leaving an edge 27. In the storage trough 26 there is a stone 28 projecting beyond the edge 27, with respect to which it is a technical ceramic. This edged stone 28 has an orange-skin-like, non-abrasive, smooth-wave-shaped micro-profiling. The same is formed by covering the rough surface of the stone 28 with glass dust and then heating it to form a thin micro-profiled layer 29, which represents the treatment area B2, see FIG. 4. In order to exclude injuries, the outer edge of the stone 28 is provided with a rounding 30.

1, 2, 3 and 4, the handle 3 is assigned to the massage head 2 in such a way that the treatment surface B1 is used.

If the orange peel-like treatment surface B2 formed by the stone 28 is to be used for a massage, the handle 3 is to be turned through 180 °, specifically after the insertion end 13 has been pulled out of the insertion shaft 12. This can be accomplished as shown in FIG. 5 is illustrated, a pressurization on the release pin end 25 'is connected with an inward displacement of the release pin 21. Its inward end acts on the tongue 15 and displaces the latching shoulder 16 from the effective area of the counter-latch 18. Now the handle 3 can be moved in the direction of the arrow y from Massage head 2 are removed. This is then to be turned through 180 ° and inserted with the insertion end 13 first into the insertion shaft 12 while bringing about the latching between the tongue 14 and the track bearing plate 8, see FIG. 6.

In Fig. 2 it is indicated by dash-dotted lines that two fastening buttons 31 protrude on the peripheral surface of the massage head 2 for a handle tab 32 shown in dash-dotted lines, which, due to the arrangement of the fastening buttons 31, extends transversely to the insertion shaft 12 and thus transversely to the longer ellipse axis. This grip tab 32 is provided when the massage head 2 is used without a handle 3.

Instead of the stone 28, a plastic body with a rough, preferably elastic surface, in particular made of an elastomer material, can also be selected. Variants of the shape that include hard material grains embedded in a plastic body, for example made of glass or a ceramic, which then determine the surface roughness. The grip tab 32 can be buttoned in such a way that either the B1 or another treatment surface B2 is used for massage.

All the features disclosed are essential to the invention. The disclosure of the associated priority documents (copy of the prior application) is hereby also included in full in the disclosure of the application, also for the purpose of including features of these documents in the claims of the present application.
