  • Publication number: 20020195510
    Abstract: A paper-guiding structure of a shredding apparatus is disclosed. The apparatus includes a first shaft, a second shaft disposed with the first shaft in parallel, wherein a channel is formed between the first shaft and the second shaft for a paper to pass therethrough. A plurality of cutters are staggeredly sleeved and fixed on the first and second shafts respectively and transmitted by the first and second shaft to rotate for cutting paper passing through the channel. A plurality of guiding plates are disposed in the space between every two adjacent cutters for each shaft, and movably sleeved on the first or second shaft. Each of the guiding plates is integrally formed and has a continuous surface facing the channel to eliminate slits through which shredded paper sneaks out of the guiding path.

  • Patent number: 5819890
    Abstract: A rigid frame garment bag travel case combination is formed in a rectilinear shaped case having opposed openable main compartments which share a common side. Each compartment is bounded by a partial rigid U-shaped frame. Between the openable compartments is a common wall provided with a separate planar frame which protects garments, especially suits or dresses, which may be hung from one compartment across the common side and into the other main compartment and secured by crossing straps. A small fold-out fabric panel attached to the lower edge of a lower main compartment is capable of holding dresses which are longer than both compartments. A larger fold-out panel is attached to one side of both main compartments and has a number of pockets for soft garments. The larger panel is folded over the openable compartments and the smaller panel. It is secured along its edge with a zipper.
