Portioning device with interchangeable scoops
A portioning device includes an integrated handle, actuating lever, and rack with teeth, with the handle having an aperture at the top. The rack is formed to be easily placed, and retained, in an initial position for assembly. One or more scoops are provided which may each be detachably connected the handle top end. A wiping blade may be detachably connected to the scoop for free rotation within the scoop. The wiping blade includes a shaft having a number of gear teeth, together with a camming surface leading to the first tooth on the shaft. Insertion of the scoop and wiping blade shaft into the handle aperture results in the first rack tooth acting as a camming surface and rotating the wiping blade to the proper clocking position with the first tooth of the shaft engaged with the first tooth of the rack. In this manner the number of component parts is reduced significantly, while at the same time allowing for re-use of the handle with the various interchangeable scoops.
1. A portioning device, comprising:
a handle unit including a handle, a lever arm articulated to said handle, and a rack connected to said lever arm such that movement of said lever arm will cause movement of said rack relative to said handle between initial and final positions, and wherein said rack is biased toward said initial position;
a scoop head including a scoop bowl, said scoop head being secured to said handle;
a wiper unit including a wiper blade intended to oscillate within said scoop bowl between initial and final positions, and a wiper rod;
said rack and said wiper rod engaging each other such that movement of said rack between said initial and final positions will cause oscillation of said wiper rod between said initial and final positions, such engagement of said rack and said wiper rod in said initial positions being an initial engagement position;
the improvement comprising one of said handle unit and said wiper unit having a cam follower thereon, and the other of said handle unit and said wiper unit having a cam surface thereon, said cam follower and said cam surface arranged to engage each other during movement of said wiper unit toward said handle unit for assembly, causing said wiper unit to rotate with respect to said handle unit such that upon completed assembly of said wiper unit to said handle unit, said wiper rod and said rack are meshed for said initial engagement position.
2. A portioning device as in claim 1 , wherein said rack includes rack teeth, and said wiper rod includes rod teeth, and said engagement between said rack and said wiper rod is engagement of said rack teeth and said rod teeth.
3. A portioning device as in claim 2 , wherein said cam follower is on said handle unit, and said cam surface is on said wiper rod.
4. A portioning device as in claim 3 , wherein in said cam follower is one of said rack teeth, and wherein said cam surface leads to a bottom land between two of said rod teeth.
5. A portioning device as in claim 1 , wherein in said rack includes a detent, and said handle includes a stop edge, said detent and said stop edge being arranged such that when said detent is abutting said stop edge, said rack is in said initial position.
6. A portioning device as in claim 5 , wherein said rack includes rack teeth, and said wiper rod includes rod teeth, and said engagement between said rack and said wiper rod is engagement of said rack teeth and said rod teeth.
7. A portioning device as in claim 6 , wherein said cam follower is on said handle unit, and said cam surface is on said wiper rod.
8. A portioning device as in claim 7 , wherein in said cam follower is one of said rack teeth, and wherein said cam surface leads to a bottom land between two of said rod teeth.
9. A portioning device as in claim 8 , wherein said handle, lever arm, rack and rack teeth are formed as a monolithic unit.
10. A portioning device as in claim 1 , wherein said scoop head is releasably secured to said handle.
