Definitions

  • the invention pertains to food processors and more particularly to a blade assembly having multiple blades in multiple cutting planes.
  • the performance of a food processor is determined, in part, by the configuration or geometry of the rotating blades. In most cases, the cutting blades of a food processor are interchangeable with other blades or other accessories.
  • a blade assembly for a food processor comprising a cylindrical hub.
  • a double ended blade is sandwiched between the upper hub portion and the lower hub portion.
  • a junction between the upper portion and lower portion is at least partially inclined with respect to a vertical axis.
  • the central double ended blade may be formed from a single blank and is retained between the upper portion and the lower portion.
  • Figure l illustrates a perspective view of a blade assembly for a food processor
  • Figure 2 is a side elevation of the assembly depicted in Figure 1;
  • Figure 3 is a top plan view of the assembly depicted in Figures 1 and 2;
  • Figure 4 is an exploded perspective illustrating the arrangement of the cutting blades
  • Figure 5 is an exploded perspective of the assembly depicted in Figures 1-3.
  • a blade assembly for a food processor 10 comprises at least one central double ended blade comprising a pair of opposed blade portions 11, 12 that are integral or formed from a single blank and which in this example occupy two distinct planes.
  • the central blade portions 11, 12 are accompanied by an upper single ended blade 13 and a lower single ended blade 14.
  • the upper and lower blades 13, 14 are diametrically opposed to one another.
  • the upper blade 13 is in vertical alignment with the lower of the two central blade portions 12 and thus forms a vertically aligned set.
  • the lower blade 14 is in alignment with the upper of the two central blade portions 11 and thus forms a second vertically aligned set.
  • four curved cutting edges are presented in four distinct cutting planes, in two vertically aligned sets using only three blanks.
  • the two sets are diametrically opposed from one another.
  • the top blade 13 and the bottom blade 14 are inverted versions of the same chamfered blade structure, both chamfers facing inwardly, e.g. toward each other.
  • the central blade portions 11, 12 are generally parallel with one another and formed from a single, bent blank.
  • the central blade portions 11, 12 extend from diametrically opposite sides of a central rim.
  • the finished blade structure incorporating the two blade portions 11, 12 thus takes on a "Z" shaped appearance.
  • the top and bottom blades 13, 14 are both parallel to one another and generally parallel with the central blade portions 11, 12.
  • Figure 3 demonstrates the vertical alignment between the upper blade
  • Figure 4 illustrates that the top blade 13 and the bottom blade 14 may be provided optionally, as identical blades, inverted with respect to one another. Each has a central opening 49.
  • the upper blade comprises a downward facing chamfer.
  • the lower blade incorporates an upward facing chamfer.
  • Figure 4 also illustrates the generally "Z" shaped configuration of the central blank 40.
  • the finished double ended blade blank 40 comprises an inclined rim or central portion 41 in which are formed a pair of fastener openings 42, 43.
  • the rim is inclined with respect to the rotational axis of the assembly 10.
  • the blank includes parallel bend lines 44, 45 where the rim joins the flat cutting blade portions 11, 12.
  • the blade portions thus extend from the rim parallel to one another but in different planes and in opposite directions.
  • the flat portions include optional fastener openings 46, 47. Note that in order to assemble the device, the fastener openings (42, 43, 45, 46) in the blank 40 must be in alignment with corresponding fastener openings in the top and bottom blades 48.
  • the hub comprises the aforementioned upper portion 51 and lower portion 52 as well as end caps, being a top end cap 53 and a lower end cap 54.
  • the top and bottom portions of the hub may be identical.
  • Each of the end caps has a flange 55, 56 that fits into the open ends of the top and bottom portions 51, 52.
  • each of the upper and lower portions 51, 52 comprise an outer wall 57 as well as an inner wall 58.
  • Each of the top and bottom portions 51, 52 of the hub have an optional peripheral rim 70 in the area where they join together to sandwich the central blank 40.
  • top and bottom end caps 53, 54 also incorporate inner and outer rims or flanges 56, 59 that preferably fit between the inner and outer walls 57, 58 of the hub top and hub bottom portions.
  • the upper end cap 53 includes a central spindle 60 and an upward facing pilot flange 61 which is used to position the inside diameter 62 of the upper blade 13. Similar structures may be found on the lower end cap 54.
  • the fasteners 50 thus pass through fastener openings in the lower blade, the lower end cap 54, the lower hub portion 52, the blank forming the central double ended blade 40, the upper hub portion 51, the upper end cap 53 and the upper blade 13.
  • the upper and lower hub portions 51, 52 together comprise a single moulded unit with the central blade 40 moulded in place at the time of manufacture.

Abstract

L'invention porte sur un ensemble à lames pour un robot ménager (10) équipé d'un moyeu cylindrique. Une lame à double extrémité (11, 12) est prise en sandwich entre une partie de moyeu supérieure (51) et une partie de moyeu inférieure (52). Dans des modes de réalisation préférés, une jonction entre la partie supérieure est au moins en partie inclinée par rapport à un axe vertical. Cette lame à double extrémité centrale (11, 12) peut être formée à partir d'une seule ébauche et est retenue entre la partie supérieure (51) et la partie inférieure (52), le moyeu pouvant aussi soutenir les lames supérieures (13) et inférieures (14) supplémentaires.
