Dumbbell set suitcase and portable fitness apparatus employing the same

Abstract

There is provided a dumbbell set suitcase comprising a cover shell and a body shell connected with each other by a connecting means, the inner side of at least one of the body shell and the cover shell are provided a plurality of recess structures for receiving the various components of a dumbbell set, and the cover shell and the body shell are pivotable upon the connecting means so that the suitcase can be switched between a closed configuration and an opened configuration, characterized in that the dumbbell set suitcase further comprises a handle portion which extends outward from the body shell, and the handle portion constitutes an integral piece together with the body shell but has no direct connection with the cover shell. The suitcase thus is of high strength, long lifetime, high reliability and convenient carriage.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a packing case for a physical training or fitness apparatus set, more particularly, to a dumbbell set suitcase and a portable fitness apparatus employing the same. BACKGROUND OF THE RELATED ART [0002] In early days, the components of a dumbbell set are generally wrapped with thin film and paper first, and then directly rested within a packing paper-box. A packing paper-box is susceptible to wetting, deformation and destruction, which cause the components of the dumbbell set to press and rub against each other, therefore the surfaces of the components can be readily scratched or damaged. Moreover, a packing paper-box typically can be used only once, it is very inconvenient to carry a dumbbell set for daily use. [0003] The inventor of the present invention proposes two types of dumbbell set suitcases in Chinese Utility Model Patents No.99205057.X and No. 99205060.X. Each of the two types of dumbbell set suitcases comprises...

AI Technical Summary

Benefits of technology

[0005] One object of the present invention is to provide a novel dumbbell set suitcase, whose structure and strength are substantially enhanced so that the reliability, safety and lifetime thereof are improved.

[0007] The handle portion may have a shape, such as a bow or other handle shape known to the persons skilled in the art, extending outward from the side of the body shell opposite to the side of the connecting means. Preferably, the thickness of the handle portion at the transitional / conjoint location between the handle portion and the body shell substantively equals to the sum of the thickness of the cover shell and that of the body shell, so that when the suitcase 100 is closed, the handle portion 103, the body shell 101 and the cover shell 102 may collectively render a smooth integral profile.

[0015] The locking holes may be of various manners and structures known to the persons skilled in the art. With the locking holes, the body shell and the cover shell can be secured together by metal thread, disposable plastic buckle, screw bolt / nut and other various flexible or rigid locking means. The second locking devices can serve to assure the safety when the suitcase is subjected to jolt or impact during transportation, and further as a tamperproof, for instance, preventing theft during product quality control, warehouse entry, storage and sale, and evidencing an original sealed product package etc.

[0016] In accordance with another aspect of the invention, the suitcase further comprises a plurality of antiskid bulges provided on bottom surface of the body shell and a plurality of antiskid pits provided on top surface of the cover shell, and the positions and dimensions of the bulges and pits are corresponding with each other so that a plurality of the suitcases will not slide on each other and thus fall down when stacked up.

Problems solved by technology

A packing paper-box is susceptible to wetting, deformation and destruction, which cause the components of the dumbbell set to press and rub against each other, therefore the surfaces of the components can be readily scratched or damaged.

Moreover, a packing paper-box typically can be used only once, it is very inconvenient to carry a dumbbell set for daily use.

However, the handling holes in the cover shell and the body shell both consume significant storage space of the suitcase.

The handle consisting of upper and lower parts (two parts) results in more complex construction as well as more stringent strength requirement for the two parts.

Both the reliability and lifetime of the cover shell and the body shell connected by the ligament-like coupler are insufficient due to the heavy weight of the dumbbell set.

Additionally, since only one pair of clasps is used as the locking device, the suitcase readily opens accidently when subjected to jolt or impact during transportation.

At this time, the drop of any components thus resulted would be great jeopardous to a user.
