KR-20260065902-A - Adjustable weight dumbbell

Abstract

An adjustable weight dumbbell comprises a handle assembly having a handle and plates at both ends. The outer surface of each plate is configured to be detachably coupled to one or more outer weights so that the total weight of the dumbbell is adjusted according to the number of outer weights connected. Additionally, the inner surface of each plate is configured to be detachably coupled to an inner weight to further adjust the total weight of the dumbbell. The inner weight may have a weight smaller than the outer weight. The adjustable weight dumbbell is supported on a cradle that facilitates the attachment and removal of the outer and inner weights as needed or desired.

Description

Adjustable weight dumbbell Cross-reference regarding related applications This application claims priority to U.S. Provisional Application No. 63/582,717, titled “Adjustable Weight Dumbbell,” filed September 14, 2023, pursuant to 35 U.S.C. § 119(e), the full text of which is incorporated herein by reference. A dumbbell is a weight training device that generally comprises a cylindrical grip handle supporting a pair of weight plates at opposite ends. Since the weight plates have a fixed weight, different dumbbells have different weights, and dumbbell sets (e.g., discrete weights of 10 to 100 pounds or more) are generally provided to offer users a variety of dumbbell weights. At least some known dumbbells include a grip handle with a carriage at opposite ends, and the carriage is configured to be optionally attached to the weight plates via a locking cartridge, allowing the user to add or remove weight as needed or desired. Improvements are required for these adjustable weight dumbbells. The information contained in this introduction, including all references cited in this document and descriptions or discussions thereof, is included for technical reference purposes only and should not be construed as subject matter limiting the scope of the invention as defined by the claims. In an exemplary embodiment, an adjustable weight dumbbell comprises a handle assembly, a first inner weight, and a second inner weight. The handle assembly comprises a handle having a first end and a second end opposite. A first plate is mounted on the first end of the handle. The first plate has a first inner surface adjacent to the handle, a first outer surface, and a first inner weight mounting structure located on the first inner surface. A second plate is mounted on the second end of the handle. The second plate has a second inner surface adjacent to the handle and facing the first inner surface, a second outer surface, and a second inner weight mounting structure located on the second inner surface. The first inner weight is configured to be detachably coupled to the first inner weight mounting structure. The second inner weight is configured to be detachably coupled to the second inner weight mounting structure. In another exemplary embodiment, an adjustable weight dumbbell comprises a handle assembly, a first inner weight, a second inner weight, and a plurality of outer weights. The handle assembly comprises a handle having a first end and a second end opposite. A first plate is mounted on the first end of the handle. The first plate has a first inner surface and a first outer surface, a first inner weight bracket disposed on the first inner surface, and a first outer weight bracket disposed on the first outer surface. A second plate is mounted on the first end of the handle. The second plate has a second inner surface and a second outer surface facing the first inner surface of the first plate, a second inner weight bracket disposed on the second inner surface, and a second outer weight bracket disposed on the second outer surface. The first inner weight is configured to be detachably coupled to the first inner weight bracket. The second inner weight is configured to be detachably coupled to the second inner weight bracket. The first and second inner weights at least partially surround the handle when coupled to the handle assembly. A plurality of outer weights are configured to be detachably coupled to the first and second outer weight brackets and detachably coupled to each other to adjust the weight of the adjustable weight dumbbell.
