Wastebasket or bin having rocking springs at bottom

Abstract

The paper shredder of this invention includes a machine body having cutting blades therein and a wastebasket or bin for containing paper chips, including a base provided beneath a wastebasket or bin; at least one support spring provided between the base and the wastebasket or bin to form an appropriate gap between the wastebasket or bin and the base, whereby when the user rocks the wastebasket or bin forwards and backwards, or sideways, chips in a chip mountain accumulated beneath the discharge port at the cutting blades can be spread outwards, to increase the space for receiving the paper chips in the wastebasket or bin, to prevent the “chip mountain” from impeding smooth falling of subsequent paper chips, thereby affecting overall operative functions of the paper shredders.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

These and other modifications and advantages will become even more apparent from the following detained description of a preferred embodiment of the invention and from the drawings in which:

FIG. 1 is a perspective view illustrating the appearance of a first embodiment of this invention, where the wastebasket or bin uses four support springs;

FIG. 2 is a cross-sectional view illustrating the relationship among the support springs, the wastebasket or bin and the base according to this invention;

FIG. 3 is a perspective view illustrating the appearance of a second embodiment of this invention, where the wastebasket or bin uses three support spring; and

FIG. 4 is a perspective view illustrating the appearance of a second embodiment of this invention, where the wastebasket or bin uses a single support springs.

DETAILED DESCRIPTION OF THE INVENTION (PREFERRED EMBODIMENTS)

With reference to FIGS. 1 to 4, the paper shredder 1 of this invention includes a machine body 12 having cutting blades 11 therein and a wastebasket or bin 13 for containing paper chips. The cutting blades engage over a rotary shaft, and the shearing force that two parallel and opposite rotary shafts produce by a motor and a gear box serve to transfer and cut the paper-to-be-cut along a longitudinal direction into strips, or further shredded in chips. The machine body 12 is provided at its surface with a paper inlet 121 parallel to the cutting blades, so as to guide the paper into the rotary shafts of the cutting blades 11 for shredding the paper.

The wastebasket or bin 13 is provided therebeneath with a base 14. At least one support spring 13 is provided between the base 14 and the wastebasket or bin 13. The support spring 13 is mounted between an upward-projecting post 141 of the base 141, and an indent 131 at the bottom of the wastebasket or bin 13 indenting inwards, so as to form an appropriate gap between the wastebasket or bin 13 and the base 14, to serve as a space where the rocking wastebasket or bin 13 may move about.

When the user rocks the wastebasket or bin forwards and backwards, or sideways, the chips in the chip mountain accumulated beneath the discharge port at the cutting blades 11 can be spread outwards, so as to increase the space for receiving the paper chips in the wastebasket or bin, and to prevent the “chip mountain” from impeding smooth falling of subsequent paper chips, thereby eliminating the defects of affecting overall operative functions of the paper shredders.

Since the paper shredder 1 and the wastebasket or bin 13 are supported by springs 15, rocking of the springs will directly affect steadiness of the wastebasket or bin 13. Accordingly, appropriate number for and locations of arranging the springs can be adjusted in accordance with the different spring characteristics. For example, in FIG. 1, four springs 15 are arranged at four corners of the wastebasket or bin 13; in FIG. 3, three springs 15 are arranged at bottom of the wastebasket or bin 13 in a triangular configuration; or in FIG. 4, a single spring 15 is arranged at a bottom center of the wastebasket or bin 13, where all arrangements can achieve the object of featuring the wastebasket or bin with rocking capability.

Accordingly, the user can rock the wastebasket or bin 13 at appropriate timing to rock the wastebasket or bin forwards and backwards, or sideways, for spreading the chips accumulated beneath the discharge port at the cutting blades outwards, so as to increase the space for receiving the paper chips in the wastebasket or bin, and to prevent the “chip mountain” from impeding smooth falling of subsequent paper chips, thereby eliminating the defects of affecting overall operative functions of the paper shredder.

In summary, this invention provides an improved paper shredder wastebasket that may not only serve as a wastebasket for containing paper shreds after the paper shredder shreds paper, but also be lifted outwards to serve as a conventional garbage bin, so as to improve the market competitiveness of the paper shredder by enhancing the functions of the wastebasket.

Claims

1. A wastebasket or bin having rocking springs at bottom, including a base provided beneath a wastebasket or bin; at least one support spring provided between the base and the wastebasket or bin to form an appropriate gap between the wastebasket or bin and the base, whereby when the user rocks the wastebasket or bin forwards and backwards, or sideways, chips in a chip mountain accumulated beneath the discharge port at the cutting blades can be spread outwards.

2. The wastebasket or bin having rocking springs at bottom of claim 1, wherein the support spring is mounted between an upward-projecting post of the base, and an indent at the bottom of the wastebasket or bin indenting inwards.
