Benefits of technology

The present invention is an improved adjustable dumbbell system that allows users to safely and efficiently change the weight to be lifted. The system includes a safety lock that can be raised or lowered to restrict or allow full rotation of the dumbbell components. The system is durable, reliable, and economically viable, making it easily available to consumers. The technical effects of the invention include improved safety, convenience, and economics.

Problems solved by technology

While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe an adjustable dumbbell system that allows for selectively varying the weight to be lifted by a user, such selective varying being done in a safe, convenient and economical manner.

Embodiment Construction

[0076]With reference now to the drawings, and in particular to FIG. 1 thereof, an exemplary embodiment of the new and improved adjustable dumbbell system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

[0077]From a broad standpoint, the present invention is a dumbbell can realize different weight choices on a single piece of rod.

[0078]The dumbbell is characterized in that the dumbbell can regulate the capacities of different weights. In other words, the dumbbell can randomly regulate one pair of dumbbell handwheels to the mark of the scheduled weight when the dumbbell is positioned on a dumbbell tray. A double safety locks system is provided and realizes the following two effects: when the dumbbell is positioned on the dumbbell tray, the dumbbell handwheels can realize choosing of gears of different weights by undergoing rotation of 360 degrees to the most. When, however, the dumbbell is positioned...

Abstract

A handle has opposed ends and a central extent. A grip rotationally receives the central extent of the handle. An adjustment wheel is secured to each end of the handle. A side cover is fixedly secured to each end of the grip. A dowel disk is on the handle adjacent to one side cover with fingers and spaces. A plurality of cam bits are supported on the handle. A safety lock is within the side cover adjacent to the dowel disk. The safety lock has a first end extent and a second end extent with a radial recess and a central extent with an axial projection. A coil spring within the radial recess urges the safety lock radially outwardly. A safety indicator may be seen on one side cover that changes from red to green as the weight selection wheel is turned, indication proper weight selection when green and a potential unsafe condition when red.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an adjustable dumbbell system and more particularly pertains to selectively varying the weight to be lifted by a user, such selective varying being done in a safe, convenient and economical manner[0003]2. Description of the Prior Art[0004]The use of exercise weight systems of known designs and configurations is known in the prior art. More specifically, exercise weight systems of known designs and configurations previously devised and utilized for the purpose of varying weight through known methods and apparatuses are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.[0005]By way of example, U.S. Pat. No. 7,261,678 issued Aug. 28, 2007 to Crawford relates to an Adjustable Dumbbell System and...
