US Classification:

401046000, 401045000

Abstract:

A writing instrument comprises: a writing tip for spreading writing fluid on surface of written media, a first reservoir chamber having a fluid outlet for supplying the writing tip with writhing fluid, a connecting sleeve for connecting the writing tip and the first reservoir chamber, in characterized that said instrument further comprises at least one additional reservoir chamber inside or outside of the first reservoir chamber, wherein each additional reservoir chamber comprises a fluid outlet, and wherein, with relative rotation between the fluid outlet of the at least one additional reservoir chamber and the connecting sleeve, the writing fluid of the at least one additional reservoir chamber is conducted to the writing tip via the fluid outlet to supply the writing tip with the writing fluid continually. The chambers are switched by way of relative rotation to supply the writing fluid continually. The writing instrument has a reasonable structure and low cost and eliminates the leakage due to the pressure and attractive force generated by internal shock or longitudinal movement of the reservoir chambers in the prior art. The writing instrument of the present invention has the advantages of simple structure, low cast and long working life.

Abstract:

A marking instrument comprising: a marking tip for applying marking fluid on surface of written media, a first reservoir chamber having a fluid supply outlet for supplying the marking tip with marking fluid, in characterized that said instrument further comprises at least one additional reservoir chamber located inside or outside of the first reservoir chamber, the additional reservoir chamber is provided with a fluid supply outlet for supplying marking fluid to the first reservoir chamber, the first reservoir chamber comprises a fluid core having absorptive capacity, and the fluid core comprises an inlet and an outlet, wherein the inlet of the fluid core communicates with the fluid supply outlet of the additional reservoir chamber and the outlet of the fluid core communicates with the marking tip, and wherein a first exhaust outlet is formed on the first reservoir chamber and communicates with the fluid core such that the marking fluid in the additional reservoir chamber is conducted to the marking tip via the fluid core of the first reservoir chamber so as to supply marking fluid continually to the marking tip. The marking instrument of the present invention not only increases the volume for marking fluid but also effectively prevents and avoids leakage. It also extends writing time and has fluent writing and even handwriting in dark or light. The marking instrument of the present invention has a simple and reasonable structure, low cost and long working life and is convenient for wholesale manufacture.

Abstract:

A balancing board may include a first and a second platform section. Each platform section may include a housing formed of a bottom housing member and a top housing member. The top housing members may have a foot placement section or area formed integrally therewith. In one embodiment, the balancing board may include a water jet that includes a water receiving space and a water fog generating unit. More specifically, when the user stands on the balancing board, the weight of the user can trigger the water jet, wherein the water can be transported to the water fog generating unit from the water receiving space and the water fog can then be generated, so there is more entertainment effect when the user stands on the balancing board.
