1. Field of the Invention
The present invention relates to handle grip of luggage and more particularly to a seamless handle grip mounted in a single pulling rod of luggage case.
2. Description of Related Art
Some types of luggage (e.g., wheeled luggage) have only a single pulling rod. For a handle grip formed on top of such pulling rod, it typically comprises an upper portion, an equal lower portion, and a push button on the upper portion. A seam is formed between a joining edge of the portions. Such seam can adversely affect a degree of comfort while holding the handle grip due to its sharp edge. A solution to the above is to improve the molds so as to substantially eliminate the seam in the manufacturing process. However, it may greatly increase the manufacturing cost. Thus, it is desirable to provide a seamless handle grip in order to overcome the above drawback of the prior art.
It is an object of the present invention to provide a seamless handle grip assembly mounted on a single pulling rod of luggage case, comprising a tube including an intermediate top opening; a top grip section including a top curved surface, a top central opening, and two bottom posts having inner threads; a spring depressible push button including a spring biased against a bottom, a circumferential bottom flange having a periphery longer than a bottom periphery of the top opening of the tube for preventing the push button mounted in the top opening of the tube from disengaging; a hollow, cylindrical left member including an enclosed left end, a top cavity at an open right end, a first positioning member adjacent the right end wherein the left member is snugly inserted into a left portion of the tube; a hollow, cylindrical right member including an enclosed right end, a top cavity at an open left end, a second positioning member adjacent the left end wherein the right member is snugly inserted into a right portion of the tube with the first positioning member matingly engaged with the second positioning member so as to confine the spring between the left and right members; a bottom grip section including a bottom curved surface, an intermediate hollow neck, and a bottom hollow section coupled to a pulling rod wherein two fasteners are driven through the curved surface of the bottom grip section, the tube, and the left and the right members into the posts for coupling the bottom and the top grip sections together with the tube fastened therein; and a rod inserted upwardly through the bottom grip section into the tube and the spring to fixedly couple to the push button.
The present invention has the following advantages:
The joining edge of the top and bottom grip sections is seamless so as to provide a degree of comfort while holding the handle grip in towing a luggage case.
The structural strength is enhanced.
It has an aesthetic appearance.
Its manufacturing cost is greatly reduced.
Most importantly, it is trouble free for long period of time of use.
The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawings.

Referring to
Note that the tube 10 can have an oval section or any other section other than above in other embodiments.
It will be evident from the foregoing that the invention has the following advantages: The joining edge of the top and bottom grip sections 21 and 22 is seamless so as to provide a degree of comfort while holding the handle grip in towing a luggage case. Moreover, the structural strength is improved so as to be trouble free. In addition, it has an aesthetic appearance due to its metal (e.g., aluminum) characteristics. Additionally, its manufacturing cost is greatly reduced.
While the invention herein disclosed has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
