MASSAGE FIXTURE IN PARTICULAR FOR DRY-SHAVING APPARATUS Filed NOV. 4, 1963 INVENTOR.

KAREL Ni. TIEMES GEN United States Patent Ofificc 3,314,418 MASSAGE FIXTURE IN PARTICULAR FOR DRY-SHAVlNG APPARATUS Karel Martin Tiemes, Drachten, Netherlands, assignor to North American Philips Company, Inc., New York, N.Y., a corporation of Delaware Filed Nov. 4, 1963, Ser. No. 321,242 Claims priority, application Netherlands, Nov. 28, 1962, 286,073 1 Claim. (Cl. 128-36) The invention relates to a massage fixture for an apparatus housing having a shaft which is driven by a motor, in particular of a dry-shaving apparatus, which fixture is provided with means for connecting massage members to the apparatus and with a'member which can be coupled to the motor of the apparatus and causes the massage member to be vibrated.

It is known to use such fixtures as intermediate members between the housing which comprises the driving motor and the actual massage members. Such massage members which are of different types and shapes, can then be connected detachably, for example, in a projecting stump of the fixture which for that purpose is provided with a bore which has screw thread.

As is normal in dry-shaving apparatus, the housing in such apparatus, which comprises the motor, also forms the grip for the opera-tion and the housing generally is given a shape so that it can be readily held in the hand.

It is known to cause massage members to be vibrated with a high frequency directly by a vibration generator located in the housing, if desired through an intermediate driving arm. It is also known to vibrate the fixture itself through a vibrating part from a rotating motor with, for example, 8 to 9000 rpm.

It is an object of the invention to render the effect of the vibration on the massage member as large as possible and the damping by holding the housing in the hand as small as possible.

The invention is characterized in that the member in the fixture which can be coupled to the motor is formed by a shaft which extends through the fixture in the longitudinal direction and is pivotally journalled, the end of which facing the apparatus housing being constructed as a coupling member with the shaft driven in the apparatus housing by the motor, the other end in the head of the fixture carrying an eccentric vibrating body.

In this manner a strong vibration is obtained exactly in the head of the fixture, so as far remote as possible from the part of the apparatus housing which is held in the hand. As a result of this arrangement, the vibration is not only very powerful but also very effectively transmitted to the massage members which can be connected to the head of the fixture. In addition, the vibration in the hand is restricted, because the play of forces and reaction by the massage members mainly occurs in an area which is restricted to the end of the fixture, as a result of which the annoying vibration of the housing of the apparatus in the hand is restricted and also the damping by the hand is small so that consequently the energy substantially benefits the massage effect.

This is the case in particular in an embodiment which is 3 ,3 14,4 1 8 Patented Apr. 18, -1 967 characterized in that at the level of the massage member the side of the fixture is provided with a connection stump for a massage member so that the energy in the plane of vibration of the massage member is transmitted as directly as possible to the massage member.

For mass-production assembly a simple and inexpensive construction is obtained in an embodiment which is characterized in that in the hollow cap a sleeve is connected, for example by screw thread, in which the shaft is journalled centrally which carries an eccentric vibrating body in the cap chamber over the sleeve, the other end of the cap being provided with a collar for the connection to the housing of the apparatus.

In order that the invention may readily be carried into effect, an embodiment thereof will now be described more fully, by way of example, with reference to the accompanying drawing, in which FIG. 1 diagrammatically shows a longitudinal section through the central axis of an embodiment of a fixture according to the invention provided with a massage member.

FIG. 2 is a side elevation of another massage memher.

The assembly of the cap-shaped fixture is indicated by 1 and the connection member formed by a collar by 2. The latter is provided at its circumference with a ribbed edge 3 and with internal screw thread 4 with which the collar can be screwed to an upright edge of the housing of the motor which is provided with external screw thread.

It may be seen in the figure that the fixture comprises a laterally projecting stump 5 with a bore 6 with a screw thread in which the stem 7 of a massage brush 8 is screwed on the stump 5. The massage member shown in FIG. 2 is formed by a rubber-like block 9 in a holder 10 provided with an end 11 which can be screwed in the chamber 6.

The fixture comprises a central spindle 12, the lower end of which comprises a slot 13 for effecting a coupling to the rotating spindle of the apparatus motor when the fixture is connected to the dry-shaving apparatus. On the other end of the spindle 12 an eccentric vibrating body -14 is provided.

The central shaft of the spindle 12 is journalled in metal bearings 15 and 16 which are included in a sleeve 17 which, as well as the cap 1, may consist of synthetic material. The sleeve 17 is screwed in the hollow cap-shaped fixture 1 by means of screw thread 18 until the rib 19 engages a shoulder in the cap. For the rotatable enclosure of the shaft 12 at the upper end a bearing disc 21 is provided in the head 20 of the fixture.

The vibrating body 14 consists of iron or a heavy alloy. It is clear that the shaft of the massage member 8 is in the area of the largest vibration amplitude and the energy is transmitted to the massage member in the most effective manner.

What is claimed is:

A vibrating massage device adapted for coupling to a rotating drive shaft of an electric motor positioned in a housing comprising a hollow, round cap, a sleeve located in said cap, a rod journalled in said sleeve and extending along the longitudinal axis of said cap, one end of said rod being adapted for coupling to said rotating drive shaft and the other end of said rod being provided with an eccentric weight that provides vibration for said massage device, said cap having an internal shoulder and said sleeve being provided with a rib which is screwconnected to the interior of said cap whereby when said sleeve is screwed a certain distance in said cap said rib engages said internal shoulder to form a stop for the further upward movement of said sleeve, said other end of said rod also having a bearing member mounted in the upper portion of said cap for maintaining said rod substantially vertical in said housing, and said cap being prov 4 r vided with a collar at the bottom thereof having means for removable connection to said housing.
