This invention relates to hand-held, powered massaging devices.
In prior U.S. Pat. No. 5,097,822 of Francis et al, my co-inventors and I disclosed a hand-held reciprocating belt massager driven by an electric motor to massage sore muscles. The opposite ends of the belt are equipped with handles, one of which houses the motor and a drive train that reciprocates the belt longitudinally when the motor is in operation. The other hand grip connects flexibly with the belt through a resilient elastomer bar that accommodates the belt reciprocation. Hand-held percussion massagers with replaceable massaging heads of varying geometries for specific applications have become popular.
A hand-held body massager includes a powered handle having an electric motor and reciprocating assembly mounted therein, and a first mating coupler of a side-release buckle assembly connected to the reciprocating assembly to impart longitudinal, reciprocating movement of the first mating coupler relative to a hand grip of the powered handle. A plurality of massaging attachments incorporating a second mating coupler of the side-release buckle assembly are interchangeably securable to the powered handle. One of the massage attachments comprises a flexible belt with the second mating coupler connected to a first end and the second end, formed from a section of elastic material, connected to a passive handle. Other attachments include a plurality of massage head attachments each including a massage head of a different geometry and having a second mating coupler of a side-release buckle assembly projecting therefrom.

A first mating portion or a first mating coupler 40 of a side-release buckle assembly 42 is reciprocally mounted on the powered handle 12 and operably connected to or coupled with the reciprocating assembly 32 which imparts longitudinal, reciprocating movement of the first mating coupler 40 of buckle assembly 42 relative to the powered handle 12. The massage belt assembly 14 and each of the massage head attachments 16 each have a second mating portion or second mating coupler 44 of the buckle assembly 42 connected thereto. In the embodiment shown, the first mating coupler 40 comprises a receiver, socket or female coupler and the second mating coupler 44 comprises a male coupler with resilient prongs 50 which are compressed when inserted into the receiver and then expand into openings 52 in the side of the receiver to secure the male coupler 44 to the female coupler 40. To disconnect the male coupler 44 from the female coupler 40, the portions of the prongs 50 extending through the openings 52 in the sides of the female coupler 40 are compressed inward and the male coupler 44 is pulled away from the female coupler 40.
The buckle assembly 42 may be a side release buckle assembly of the type shown in U.S. Pat. No. 5,465,472. It is foreseen that other types of buckles or connectors could be used to connect the attachments to the powered handle 12. It is also foreseen that the male coupler 44 of the buckle assembly 42 could be secured in the end of the powered handle 12 and connected to the reciprocating assembly 32 and the female coupler 40 could be connected to the attachment.
In the embodiment of the buckle assembly 42 shown, the openings 52 formed through sides of the female coupler 40 are surrounded by or defined by a barb engaging portion 54 of a sidewall 56 of the female coupler 40 at a distal end of the opening 52. Each barb engaging portion 54 of the female coupler sidewall 56 may be described as facing rearward or toward the hand grip 18 of the powered handle 12.
Each prong 50 includes a barb 62 formed on an end of a stem 64 connected to and projecting outward from a base 66 of each massage head attachment 16 opposite a respective head 41a, 41b, 41c, 41d, 41e, and 41f. Each barb 62 slopes outwardly and toward the massage head attachment base 66 and forms an abutment surface 68 projecting outward relative to the stem 64. In a preferred embodiment, the abutment surface 68 slopes slightly toward the massage head attachment base 66 as it extends outward from the stem 64 to which it is attached. When the prongs 50 of a selected massage head attachment 16 are inserted into the female coupler 40, the prongs 50 initially compress as the outer surface of each barb 62 advances past a distal end of a respective female coupler sidewall 56. As the abutment surface 68 of each prong 50 is subsequently advanced just past the barb engaging portion 54 of the respective female coupler sidewall 56, the barbs 62 expand outward so that the abutment surface 68 of each barb 62 extends in overlapping relationship with a respective barb engaging portion 54 of the associated female coupler sidewall 56 to resist or prevent withdrawal of the prongs 50 of the male coupler 44 from the female coupler or socket 40 without first compressing the barbs 62 inward. Compressing the barbs 62 inward advances the abutment surface 68 of each barb 62 inward past the adjacent barb engaging portion 54 of the respective female coupler sidewall 56 to allow withdrawal of the prongs 50 from the female coupler or socket 40.
In the embodiment shown in
The interchangeable massage head attachments 16 each include a head 41a, 41b, 41c, 41d, 41e, and 41f of a different geometry with one of the second mating couplers 44 of the buckle assembly 42 fixed to and projecting away from the respective head 41a-41f. Each massage head attachment 16 is releasably securable to the first mating coupler 40 on the powered handle 12 by their respective second mating coupler 44 of the buckle assembly 42. Reciprocation of the first mating coupler 40 by the motor 30 and reciprocating assembly 32 in powered handle 12 causes percussive massage or longitudinal reciprocal motion of the massage head attachment 16 secured thereto. The heads 41a-41f of massage head attachments 16 include different geometries to enable directing of impacts from the head 41a-41f to different portions of a user's body and to vary the application of the impacts and the massaging effect. When the second mating coupler 44 of the buckle assembly 42 and attached belt 80 are removed from the first mating coupler 40 on powered handle 12, the selected massage head attachments 16 with the second mating coupler 44 of the buckle assembly 42 may be interchangeably inserted within the first mating coupler 40 of the buckle assembly 42 reciprocally mounted on the powered handle 12. An embodiment of the massaging assembly or apparatus 10 preferably includes at least one of the massage head attachments 16 and at least one massage belt assembly 14. In addition to multiple massage head attachments 16 of different geometries, it is foreseen that the apparatus could include multiple belt assemblies 14 with belts 80 of different materials or widths or other variations to vary the massaging action.
In the embodiments shown in
The massage belt assembly 14 and massage head attachments 16 are longitudinally reciprocated by the reciprocating assembly 32 and the electric motor 30 which are mounted within the hollow portion of the handle body 20 forming part of the powered handle 12. The electric motor 30 is preferably a multi-speed electric motor which has multiple speeds of operation. In the present embodiment the electric motor 30 is a four-speed electric motor which is mounted on a motor mount 140 and the motor mount 140 is mounted to projections extending internally on the interior surface of the handle body 20. When energized, the motor effects rotational motion of a an output shaft or drive shaft 142 extending from the electric motor 30 and the drive shaft 142 engages the reciprocating assembly 32, which in the embodiment shown comprises a slider-crank mechanism, to convert rotary motion of the drive shaft 142 into linear motion and effect the longitudinal reciprocating motion of the massage belt assembly 14 or massage head attachments 16.
In the embodiment shown, the drive shaft 142 includes a flattened side 146 to form a D-shaped cross-section adapted to mate with a D-shaped through-hole 148 formed on a crank base 160. The crank base 160 is secured to the drive shaft 142 by a set screw 162 extending laterally through a threaded set screw hole 164 in a notched section 166 on the side of the crank base 160 and intersecting with the flat surface 146 of the drive shaft 142 securing, through pressure and friction, the drive shaft 142 to the crank base 160.
As best shown in
The distal end 180 of the crank arm 172 is rotatably connected to a slider 182 through a distal end bearing assembly 184. The crank arm 172 is shown formed with a bend to facilitate connection of the distal end 180 of the crank arm 172 to the slider 182. The slider 182 is formed on an inner end of the first mating coupler 40 of the side-release buckle assembly 42. Longitudinally oriented flanges 186 and 188 project laterally outward from sides of the slider 182 and are received in longitudinally oriented slots 190 and 192 formed in slider guiding members or brackets 194 and 196 mounted within the handle body 20. The guiding brackets 194, 196 and slots 190, 192 limit the movement of the slider 182 to a longitudinal, reciprocating movement. The reciprocating assembly 32 imparts substantially longitudinal, reciprocating movement to the first mating coupler 40 of the side-release buckle assembly 42 relative to the powered handle 12.
