SHREDDER
A shredder including a shredder mechanism and a feed mechanism, wherein the feed mechanism includes a first rotatable roller and a second rotatable roller to advance a material therebetween to the shredder mechanism for shredding, wherein at least one of the first roller and the second roller contacts an intermediate portion of the material to facilitate a feeding of the intermediate portion therebetween.
1 . A shredder comprising:
a housing including a feed bed formed therein, wherein the feed bed receives a material to be shredded therein;
a shredder mechanism disposed in the housing, the shredder mechanism including at least one cutter element to convert the material to a shredded material; and
a feed mechanism disposed in the housing, the feed mechanism including a first roller and a second roller located adjacent an intermediate portion of the feed bed, the first roller and the second roller cooperating to advance an intermediate portion of the material in a direction towards the shredder mechanism.
2 . The shredder according to claim 1 , wherein one of the first roller and the second roller contacts the intermediate portion of the material to facilitate a feeding of the intermediate portion between the first roller and the second roller.
3 . The shredder according to claim 1 , wherein a direction of rotation of the first roller is opposite a direction of rotation of the second roller.
4 . The shredder according to claim 1 , further comprising a panel pivotally coupled to the housing to provide access to the feed bed.
5 . The shredder according to claim 4 , further comprising an advancement mechanism coupled to the panel, where the advancement mechanism causes the material to be pressed against at least one of the first roller and the second roller.
6 . The shredder according to claim 5 , wherein the advancement mechanism is a substantially planar plate.
7 . The shredder according to claim 5 , further comprising at least one urging member disposed between the panel and the advancement mechanism, wherein the at least one urging member exerts a force on the advancement mechanism.
8 . The shredder according to claim 5 , wherein the advancement mechanism includes a buckling member disposed thereon to facilitate a feeding of the material into the feed mechanism.
9 . The shredder according to claim 5 , wherein the advancement mechanism includes a low-friction zone abutting at least a portion of the material.
10 . The shredder according to claim 5 , wherein the advancement mechanism includes a high-friction zone abutting at least a portion of the material.
11 . The shredder according to claim 1 , further comprising at least one cross-member extending between side supports of a frame of the housing.
12 . The shredder according to claim 1 , further comprising at least one buckling guide disposed in the housing to direct the material between the first roller and the second roller.
13 . The shredder according to claim 1 , further comprising a third roller disposed in the housing to abut at least a portion of the material.
14 . The shredder according to claim 13 , wherein a direction of rotation of the third roller is the same as a direction of rotation of the second roller.
15 . A shredder comprising:
a housing including a feed bed formed therein, wherein the feed bed receives a material to be shredded therein;
a shredder mechanism disposed in the housing, the shredder mechanism including at least one cutter element to convert the material to a shredded material;
a feed mechanism disposed in the housing, the feed mechanism including a first roller and a second roller, wherein one of the first roller and the second roller contacts an intermediate portion of the material to advance the intermediate portion of the material therebetween in a direction towards the shredder mechanism; and
a panel coupled to the housing to provide access to the feed bed, the feed bed defined by an advancement mechanism coupled to the panel, wherein the advancement mechanism causes the material in the feed bed to be pressed against one of the first roller and the second roller.
16 . The shredder according to claim 15 , wherein the advancement mechanism includes a buckling member disposed thereon to facilitate a feeding of the material into the feed mechanism.
17 . The shredder according to claim 15 , wherein the advancement mechanism includes a low-friction zone abutting at least a portion of the material.
18 . A shredder according to claim 15 , wherein the advancement mechanism includes a high-friction zone abutting at least a portion of the material.
19 . A shredder comprising:
a housing including a feed bed formed therein, wherein the feed bed receives a material to be shredded therein;
a shredder mechanism disposed in a housing, the shredder mechanism including at least one cutter element to convert the material to a shredded material;
a feed mechanism disposed in the housing, the feed mechanism including a first roller, a second roller, and a third roller, wherein the first roller and the third roller contact an intermediate portion of the material to advance the intermediate portion of the material between the first roller and the second roller in a direction towards the shredder mechanism, and wherein a direction of rotation of the second roller is opposite a direction of rotation of the first roller and a direction of rotation of the third roller is the same as the direction of rotation of the second roller; and
a panel coupled to the housing to provide access to the feed bed, the feed bed defined by an advancement mechanism coupled to the panel, wherein the advancement mechanism causes the material in the feed bed to be pressed against the first roller and the third roller.
20 . The shredder according to claim 19 , wherein the first roller and the second roller are located adjacent an intermediate portion of the feed bed.
