Definitions

  • This invention relates to improvements in self-massage apparatus of the belt type, that is in which a rapidly reciprocating belt embraces the body of the user who leans or pulls against it.
  • Fig. 1 is an end elevation, partly in section to illustrate the construction of the crank and related parts of a preferred embodiment of the invention
  • Fig. 2 is a rear elevation of the apparatus shown in Fig. l with parts broken away for purposesrof clarity
  • Fig. 3 is a plan view with the upper portions of the housings in section
  • Fig. 4 is a plan view of the entire apparatus.
  • M designates an electric motor which constitutes a prime mover for giving consta-nt motion to the massaging apparatus.
  • Y This motor is secured bymeans of a plurality of bolts B to a base plate l? made of metal. in order to form a weighty base for vthe device and to give stability thereto.
  • Underneath the base plate a cushion C of felt, rubber or like frictional material may be secured to dampen movement of the machine aswell as tol prevent injury to the supporting surface upon which the device may be placed during operation and reduce noise. It is not necessary to utilize the cushion C but in place thereof thev base plate may rest directly upon a bath towel T or other absorbing surface which is equally as eilicient as the cushion C.
  • the electric motor has shaft extensions S projecting at each end thereof and upon each of which shaft ends'is mounted a disk crankand arm 1 with which a counterweight 2 is integrally cast.
  • Each counterweight 2 is positioned opposite its companion crank and the crank arms are arranged 180 apart.
  • the crank arms and counterweights are ⁇ secured to the shafts S by the set screws 20.
  • the crank arms 1 are .operatively connected by the connecting rods 3 to actuate plungers 4 by means of the wrist pins 6 and crank pins 6.
  • the plungers 4 are made of thin wall steel tubing within which is forced an aluminum block 4 to afford support for the wrist pins 6.
  • the plungers 4 slide in and out of the housings H, which housings are preferably made of cast iron and mounted on the base plate P by means of Aal plurality ofbolts 7.
  • the portions 5 of the housings Hare suitably shaped to constitute bearings to support the plungers 4 and the parts which the housing enclose constitute the transmission mechanism by means of which the motor reciprocates the massage belt, such mechanism being thus disposed onv opposite sides of the motor and in horizontally adjacent positions with relation thereto.
  • the cast iron housings H are also designed with oil sumps 8 of lsuch a size as to contain a suliicient amount of oil to lubricate all of themoving parts for a long period of time.
  • the oil scoops 18 carried by the armsB dip into the oil contained in the sumps and splash oill to all of the parts requiring lubrication. Oil may b e introduced into the sumps through the oil fillers O.
  • the ends'13 of the plungers 4 are provided with suitable clamps 14 for attaching the ends 15 of a massaging'device or applicator belt 16 thereto.
  • felt washers are provided around the shafts S and next to the ends of the motor.
  • Surplus oil, carried by the scoop 18 to the surfaces of the plungers 4, is wiped therefrom by the bearing surface 5.
  • Such surplus oil drains 4back into the oil sump 8 through channels lland ducts 11a which are preferably cast directly in the housing.
  • the apparatus can be made to operate practically in complete mechanical balance by suitably proportioning the weight of the plungers and the counterweight on the crank arms.
  • each housing acts like an air compressor.
  • a tube or pipe 19 I neutralize the pressure iuctuations in the two housings so as to reduce the tendency for the oil to escape past the washers.
  • This pipe also serves as a very convenient handle for carrying the device or for putting it away when not in use.
  • a hold-back strap 21 or equivalent device may be fastened to my apparatus and then secured to any convenient fixture in a room, such as a radiator, door knob, or a hook fastened in the wall or floor as shown in Figures land 4.
  • the adjunctive restraints are not made to'prevent such movement, but merely to dampen it, for it is important to this invention that the machine shall have freedom to move to some extent under the effect of its own reaction forces.
  • the hold-back device is a non-rigid form of connection designed to permit such movement while at the same time sustaining the users pull on the machine so that he may not displace it from its working position or pull it off the table.
  • the hold-back may also serve to dampen or limit the reaction movement under heavier loads as later described.
  • ythe reaction movement or tendency of the machine to vmove on its support is a tendency to oscillate about its center of mass, which is substantially its geometric center and, in thisV preferred form, the organization of the machine with considerable and preferably equal portions of its mass on opposite sides of the median plane between the belt connectors and at substantially equal distances therefrom, constitutes the most effective wayof ⁇ utilizing its. inertia and suiices to keep the machine nearly stationary under ordinary user load, while imparting the least vibration to the part ofthe building to which the hold-back means has been fixed, which is to say that the least duty is thus imposed on the holdback means so far as absorbing the reaction is concerned.
  • crank housings at the opposite ends of the base together with the end portions of the latter constitute adequate masses for this purpose.
  • my invention contemplates providing a massage apparatus of thereducer or exerciser type which is completely enclosed to form a unitary, simple, and compact device, which has all of the moving parts thereof and the lubricantcontained in a housing, which requires no special room or place but may be placed on an ordinary table or bed in a bed-room, library, or dining room, etc. or may be suspended from a hook in a ceiling, which needs no oiling or other attention for a long period of time; which Weighs only about one third or one fourth of the weight of machines now on the market and costs much less than known machines; and which is absolutely safe for the lay users.
  • a machine comprising a base, an electric motor and belt connector means driven thereby to reciprocate the belt, the total weicht of said machine being correlated to the reciprocating speed to produce an inertia effect so proportioned to the massage resistance that the belt reciprocates and the machine bodily vibrates through an appreciable amplitude when at work, supporting means for said machine permitting such movement, a hold-back device to sustain the users pull also permitting such movement, and a massage belt connected by its ends to said belt-reciprocating means.
