Each shell includes a shell body defining an accommodation chamber therein for containing liquid so as to increase the weight of the dumbbell, and a tubular portion defining an access port that provides access to the accommodation chamber. The access port is closed by the respective coupling end of the neck member. A light-related brightening member is disposed in one of the shells and the neck member for illumination and embellishment.
Description
- This application is a continuation-in-part of U.S. patent application Ser. No. 10/669,939, filed by the applicant on Sep. 24, 2003, the entire disclosure of which is incorporated herein by reference.
- 1. Field of the Invention
- This invention relates to a hollow dumbbell, more particularly to a hollow dumbbell with a detachable construction for convenient carrying.
- 2. Description of the Related Art
- In co-pending U.S. patent application Ser. No. 10/669,939, the applicant disclosed a hollow dumbbell that includes right and left shells respectively defining accommodation chambers for containing liquid therein so as to increase the weight of the dumbbell, and a hollow neck member for gripping purposes. The neck member defines a passage therein which is in fluid communication with the accommodation chambers. An access port is formed on one of the right and left shells and the neck member to provide access to the accommodation chambers and the passage, and is closed by a detachable plug. A light-related brightening member, such as a battery-powered lighting body, and fluorescent flakes, etc., is disposed on or in one of the shells and the neck member for enhancing the fun of exercising using the dumbbell.
- It is desirable to improve the aforesaid hollow dumbbell to facilitate carrying.
- An object of the present invention is to provide a hollow dumbbell which has an appealing appearance and which has a detachable construction to facilitate carrying.
- According to this invention, the hollow dumbbell includes left and right shells, each including a shell body which defines an accommodation chamber adapted for containing liquid therein so as to increase the weight of the dumbbell, and a tubular portion which extends along a longitudinal axis from the shell body and which defines an access port that provides access to the accommodation chamber. A neck member is elongated along the longitudinal axis, and has left and right coupling ends opposite to each other along the longitudinal axis. A left fastening member is disposed to detachably connect the tubular portion of the left shell to the left coupling end so as to close the access port in the tubular portion of the left shell. A right fastening member is disposed to detachably connect the tubular portion of the right shell to the right coupling end so as to close the access port in the tubular portion of the right shell. A light-related brightening member is disposed in one of the left and right shells and the neck member.
- Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments of the invention, with reference to the accompanying drawings, in which:
-
FIG. 1 is an exploded plan view of a preferred embodiment of a hollow dumbbell according to this invention; -
FIG. 2 is a sectional view of the preferred embodiment; and -
FIG. 3 is a sectional view of another preferred embodiment of a hollow dumbbell according to this invention. - Before the present invention is described in greater detail, it should be noted that same reference numerals have been used to denote like elements throughout the specification.
- Referring to
FIGS. 1 and 2 , the preferred embodiment of a hollow dumbbell according to the present invention is shown to comprise left andright shells 4, aneck member 3, left and right fastening members, a light-related brightening member. - The left and
right shells 4 and theneck member 3 are made from a transparent rubber or plastic material. Preferably, the transparent rubber or plastic material has incorporated therein a fluorescent substance. Each of the left andright shells 4 includes ashell body 41 which defines anaccommodation chamber 42 adapted for containing liquid, such aswater 7, and atubular portion 43 which extends along a longitudinal axis from theshell body 41 and which defines anaccess port 431 that provides access to theaccommodation chamber 42. Theneck member 3 is elongated along the longitudinal axis, and has left andright coupling ends right shells 4 are patterned onouter surfaces 411 thereof for enhancing the appearance of the dumbbell. - Each of the left and right fastening members includes internally and externally threaded
surfaces tubular portion 43 of a respective one of the left andright shells 4 and a respective one of the left andright coupling ends right coupling ends tubular portion 43 of a respective one of the left andright shells 4 and so as to close therespective access port 431. In addition, a water-tight ring 5 is sleeved on each of the left and right coupling ends 31,32, and engages thetubular portion 43 of the respective one of the left andright shells 4 so as to establish a water-tight engagement between the internally and externally threadedsurfaces neck member 3 defines apassage 33 therein which extends along the longitudinal axis and which has two ends that are respectively disposed in the left andright coupling ends accommodation chambers 42 in the left andright shells 4, respectively. In this embodiment, arecess 34 is formed in an outer surface of theneck member 3, and extends inwardly towards thepassage 33. The light-related brightening member includes a battery-poweredlighting body 6 received in therecess 34. Thelighting body 6 includes twoilluminating portions 61 and acontrol switch 62 connected electrically to theilluminating portions 61. Alternatively, afluorescent bar 6′ made from a fluorescent material may be used, as shown inFIG. 3 . - In use, the
lighting body 6 is first inserted into therecess 34. Then, one of the left andright shells 4 is connected to therespective coupling end neck member 3.Water 7 is introduced through theother coupling end passage 33 and theaccommodation chamber 42. If desired, a plurality offluorescent bodies 8, such as fluorescent pellets or flakes, can be disposed in thepassage 33 and theaccommodation chamber 42 to be mix with or to scatter in thewater 7. Finally, the other one of the left andright shells 4 is connected to theother coupling end lighting body 6 is retained in therecess 34 steadily. - Since the dumbbell of this invention includes left and
right shells 4 which are in a threaded engagement with theneck member 3, theshells 4 can be separated from theneck member 3 for convenient carrying and storage. Moreover, theaccess ports 431 in theshells 4 are closed by thecoupling ends neck member 3 without the need for a plug. - Referring to
FIG. 3 , another preferred embodiment of a hollow dumbbell according to this invention is shown to be similar to the previous embodiment in construction, except that theneck member 3′ is made from a metal material and is not formed with a passage. Aflexible strap 9 is fastened around theneck member 3′ to facilitate gripping. A plurality of battery-poweredlighting bodies 6 andfluorescent bars 6′ are received in a plurality ofrecesses 44 that are formed in outer surfaces of the left andright shells 4. The left and right coupling ends 31′ of theneck member 3′ have externally threadedsurfaces 311′,321′ in threaded engagement with the internally threadedsurfaces 432 of thetubular portions 43 of the left andright shells 4. Thus, the user can grip themetal neck member 3′ more steadily. - While the present invention has been described in connection with what is considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretations and equivalent arrangements.
