Shaft device use for tape dispenser stands

Abstract

A shaft device used for tape dispenser stands so that a roll of tape may be retained and dispensed. The shaft device comprises two shaft casings, two springs and two covers. Each of the two shaft casings is a hollow body. The closed end of each shaft casing has an angled upper surface and an angled lower surface. The flange of each shaft casing is provided with a transverse groove. Each cover is positioned at the end opposing the corresponding casing, and each spring is retained in the space between a shaft casing and the corresponding cover. Each of the two covers is disposed at an outer end, and each of the two shaft casings is fixedly disposed into the corresponding inner surface of the space between the two supports. With the two springs and the two covers in place, each shaft casing can compress outwards towards the corresponding cover to allow a user to insert a roll of tape into or remove it from the dispenser stand. Also, after a roll of tape is properly inserted, the two shaft casings can extend inwards to hold the roll of tape in place and then can allow the dispensation of the tape.

What is claimed is:  
     
         1 . A shaft device used for tape dispenser stands, comprising two shaft casings, two covers and two springs, wherein: 
 Each of the two shaft casings being a hollow body with an open end and a closed end, the closed end forming a protrusion, the closed end of each shaft casing having an angled upper surface and an angled lower surface, the open end has a flange;    Each of the two covers having a closed end and an open end, the open end being provided with a multiple of engagement legs; and    Each shaft device being disposed in a side support, a hollow portion being provided in each of the two supports, each shaft casing extending beyond the space between the two supports, each of the two covers being fixedly disposed at an outer end, each spring being retained in the space between a shaft casing and the corresponding cover.    
     
     
         2 . The shaft device of  claim 1 , wherein the flange of each shaft casing has a transverse groove.  
     
     
         3 . The shaft device of  claim 2 , wherein a small protrusion which can mate with the said groove is provided on the inner surface of the corresponding hollow portion.
