Abstract
A remote controlled vibration imparting device for a concrete finishing tool includes a case that attaches to a float using standard bolt layouts. A motor housing is suspended in and attached to the case, and the motor housing partly surrounds a vibrator with a support, a rotor with a shaft and weighted body, a bi-directional motor, and a coupler between the shaft and the motor. Also in the case are a variable speed controller and a remote switch, both of which are electrically connected to the motor and a battery located on or in the case. The case further includes a removable lid that attaches to a concrete finishing tool.
Claims20
A vibrator mechanism usable with a concrete finishing tool and a float having industry standard float adaptor bolt layout, the vibrator mechanism comprising:
- a. a case comprising a lid and defining a case chamber, wherein the case is configured to cooperate with the float's industry standard float adaptor bolt layout and the lid is configured to cooperate with the concrete finishing tool;
- b. a motor housing removably attached to and positioned within the case chamber wherein the motor housing defines a housing chamber;
- and
- c. a vibrator positioned at least partly within the housing chamber of the motor housing wherein the vibrator comprises:
- i. a bi-directional motor comprising an output shaft;
- ii. a support, wherein the support defines a bore therethrough;
- iii. a rotor located at least partly within the bore of the support and being adapted to turn relative to the support, wherein the rotor comprises a shaft extending outwardly from the rotor and a weighted body connected to the shaft;
- and
- iv. a resilient link connecting the output shaft of the motor to the rotor shaft.
A vibrator mechanism usable with a concrete finishing tool and a float having industry standard float adaptor bolt layout, the vibrator mechanism comprising:
- a. a case comprising:
- i. a substantially rectangular bottom section defining a plurality of pillars and configured to cooperate with the float's industry standard float adaptor bolt layout;
- ii. opposing front and back sides and opposing first and second ends fixedly attached to the bottom section around its perimeter to define a case chamber;
- and
- iii. a lid removably attached to the front and back sides and first and second ends at a spaced distance from the bottom section, wherein the lid is configured to cooperate with the concrete finishing tool;
- b. a motor housing comprising an inner surface and a plurality of protrusions, wherein the motor housing inner surface defines a housing chamber and wherein the motor housing protrusions removably attached to the case bottom section pillars with fasteners;
- c. a vibrator positioned at least partly within the housing chamber of the motor housing wherein the vibrator comprises:
- i. a bi-directional motor attached to the motor housing at a spaced relationship from the motor housing inner surface with a plurality of set screws, the bi-directional motor comprising an output shaft;
- ii. a support, wherein the support defines a bore therethrough;
- iii. a rotor located at least partly within the bore of the support and being adapted to turn relative to the support, wherein the rotor comprises a shaft extending outwardly from the rotor and a weighted body connected to the shaft;
- iv. a coupler connecting the output shaft of the motor to the rotor shaft;
- and
- v. a bearing positioned between the support and the rotor;
- d. a variable speed controller positioned in the case chamber and in electrical communication with the motor;
- and
- e. a variable speed input positioned on the case and in electrical communication with the variable speed controller.
