Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to shaving devices. 
     Shaving devices of different types are known in the art. Usually, during the use of a shaving device with razor blades, first the user applies a shaving cream on the skin and distribute it over the skin and then the shaving device with the razor is used to shave the hair. The known shaving devices possess several disadvantages. First of all, they are not used for applying and distributing the shaving cream on the skin. It is necessary to apply to distribute the shaving cream on the skin by an additional device or by hand which is inconvenient and unpleasant. The known shaving devices with razor blades do not massage the user&#39;s skin during shaving. These and other disadvantages make desirable to improve the construction of existing shaving devices. 
     SUMMARY OF THE INVENTION 
     Accordingly, it is an object of the present invention to provide a new and improved shaving device, which avoids the disadvantages of the prior art. 
     In keeping with these objects and with others which will become apparent hereinafter, one feature of the present invention resides, briefly stated, in a shaving device which has a hollow handle with an inner chamber, a head, means for supplying the shaving cream from the inner chamber of the handle through the head onto the user&#39;s skin, bruch means for distributing the shaving cream on the user&#39;s skin, and shaving means for shaving the user&#39;s hair. 
     When the shaving device is designed in accordance with the present invention, it simultaneously applies and distributes the shaving cream and shaves the hair on the user&#39;s skin. When the shaving device is provided with additional massaging means, it also massages the skin which further improves the quality of the shaving. The inventive device is easy to wash, much more convenient to sue since it simultaneously performs several operations. 
     The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     As can be seen from FIGS. 1 and 2, the device in accordance with the present invention has a handle which is identified as a whole with reference numeral 1. The handle has an inner hollow with a wider part 2 provided with a thread 3 closeable by a plug 4 provided with a further thread 5. The handle 1 also has a narrow part 6 of an oval cross-section. 
     A head 7 is mounted on the handle 1. The head has longitudinal passages 8 with outlet openings 9 which are offset radially from the axes of the passages 8. Balls 10 are retained in the recesses 9 and provided with a plurality of very small depressions 11. The balls 10 are retained in the recesses 9 by shoulders 12 projecting slightly beyond the maximum radius of the balls forwardly. 
     A central unit 13 is connectable with the head 7 by interengagement of a projection 14 provided in the head with the projections 15 provided in the central unit. Cylinders 16 in which the passages 8 are formed engage in a recess 17 provided at the front end of the central unit 13. A bush 18 projecting forwardly from the center unit 13 engages between the cylinders 16. Bushes 19 are located in the interior of the central unit 13 and can carry springs 20 in the assembled condition. Projections 21 of a push button 22 extend into the interior of the bushes 19 and have arresting formations 23 which are arrested pistons 24 movable in the passages 8. Arresting formations 25 fix the button 22 in the interior of the central unit 13. The elements 16, 24, 20, 23, 21 and 22 form together a pump for sucking water preferably warm water into the passages 8 and then expelling warm water from the passages 8 toward the balls 10. Openings 25 provided on the front surface of the head serve for passing the water therethrough into the passages 8 and from the passages 8. The openings 25 communicate by connecting passages 26 with the passages 8. 
     A pump for supplying a shaving cream 2 to the central area of the head between the balls 10 includes an inlet pipe 27, a housing 28 located in the handle and having cylinder portions 29, 30 and 31, valve members 32 and 33 located in the cylinders 29 and 30, a push button 34 provided with a spring 35 and a rod 36 which is connected with a piston 37 movable in the cylinder 38. A bush 39 is located rearwardly of the piston 37 and has a central opening 40 through which the projections 36 extend to engage the piston 37. 
     The head 7 is provided with a guide 41 formed for example with a dove-tail shaped groove 42. A shaving element 43 is movable in the groove 42. The shaving element includes a holder 44 with a front end on which a shaving cartridge 45 is fittable. The shaving element has a rear part 46 provided with a passage 47 for receiving a spring 48 and a ball 49. The bottom wall of the groove 42 is provided with two depressions 50 and 51. The shaving element 43 can move along the groove 42 and be fixed in its rear position shown in FIG. 3 in a solid line or a front position shown in a broken line. 
     Brushes 52 are insertable in recesses 53 formed at the sides of the head 7. The brushes 52 project forwardly somewhat beyond the front surface of the balls 10. 
     The head has openings 54 for supply water into the cylinders 8. The head also has a central passage 55 communicating with an outlet opening 56 for supplying the shaving cream. 
     The device operates in the following manner: 
     First of all, the button 22 is pushed forwardly toward the front end of the head or toward the balls 10 so that the pistons 24 are brought actually in contact with the rear surface of the ball 10. Then the head is immersed into a warm water and the button 22 is released. Under the action of the spring the button is moved to the right in an opposite direction and pulls the pistons 24 away from the balls so that the warm water is aspirated into the passages 8 through the openings 54. Then the push button 34 is pushed inwardly and released several times so that it moves back under the action of the spring. During the rearward movement of the piston 37 the shaving cream is aspirated through the pipe 27 from the inner hollow of the handle into a chamber formed between the balls 32 and 33. During subsequent push of the button 34 inwardly, the dose of the shaving cream is pressed through the cylinder 30 into the pipe 30&#39; and then exits through the tubular element 18 through the central opening 56. When the head is applied on the skin of the user, the paste is expelled on the skin and the head is moved along the skin, the shaving cream is applied to the skin, the balls then rotate and entrain a thin film of water from the passages 8 so as to apply it on the layer of the shaving cream on the skin, and the brushes 53 uniformly distribute the shaving cream and water and make a foam on the skin. When the skin of the user is covered with the foam the shaving element 43 is moved from its rear position to its front position, and the user shaves the hair on the skin by the razor 45 of the shaving element 43. It is however possible to apply the shaving cream on the skin without supplying additional water. 
     The invention is not limited to the details shown since various modifications and structural changes are possible without departing in any way from the spirit of the present invention.
