1. Field of the Invention:
The present invention relates to a grinder, especially to a grinder having features of manually operated and labor saving.
2. Description of Related Art:
In cooking, spices in a powder shape or particle shape are commonly used, such as pepper powders, sesame powders or coffee powders (hereinafter all referred as spice), the particle-shaped or sheet-like solid member is ground into powders for being easily dissolved and evenly distributed in foods or liquid.
A conventional grinding means is to dispose the particle-shaped or sheet-like spice in a grinder then directly grind manually or electrically the particle-shaped or sheet-like spice into powders such as sesame powders or pepper powders for being added in foods, soup or coffee powders for being brewed. The Taiwan Patent NO.367805 and the Taiwan Patent NO.415215 (corresponding to the U.S. Pat. No. 5,865,384) both granted to the applicant of the present invention have respectively disclosed an electrical grinder and a manual grinder, in which the interior of a hollow housing formed in the grinder is served to accommodate the objects to be ground, e.g. pepper particles, and the top of the housing is provided with a driven device, e.g. an electrically powered device or a manual rotating seat.
Take the Taiwan Patent NO.415215 for example, when the manual grinder is in use, the users holds the housing with one hand, and the other hand holds a rotating seat for the purpose of rotation, so a spindle and a rotating grinding disk relative to a fixed grinding base are driven to rotate, the particle-shaped or sheet-like spice received between the grinding disk and the grinding base is ground by grinding teeth of the grinding base and disk teeth of the grinding disk thereby obtaining powders, then discharged from a base disk of an adjusting device so as to be sprinkled on foods.
The above-mention manual grinder requires a hand to directly hold the rotating seat for the purpose of rotation, because the force arm of the rotating seat is relatively shorter, the labor and time required for operation become relatively greater. As such, the skilled people in the art have developed a design of additionally installing a rotatable handgrip on a coffee bean grinder for driving a spindle and a rotating disk relative to a fixed grinding base to rotate, the installation of the rotatable handgrip allows the force arm at the force applying end to be longer thereby saving labor in operation; however, the rotatable handgrip is formed in a horizontal status which cannot be folded and the length thereof is fixed, in other words the length of the rotatable handgrip cannot be greater than the maximum outer diameter of the coffee bean grinder for preventing the package volume from increasing, but it is well known that the longer the force applying end, the less labor in operation, so how to additionally install a rotatable handgrip on a grinder and having a length greater than the maximum outer diameter of the grinder without increasing the package volume shall be seriously concerned.
One primary objective of the present invention is to provide an improvement for a grinder, in which a rotatable handgrip capable of being automatically folded and upwardly lifted is installed, so the length of the rotatable handgrip is allowed to be greater than the maximum outer diameter of the grinder without increasing the package volume, thereby providing advantages of labor saving, time saving and easy operation.
For achieving the objective, the present invention provides an improvement for a grinder, which includes: a grinder, the top thereof is formed with a top cover; and a rotatable handgrip, the inner side thereof is swingably pivoted with the radial periphery of the top cover, the outer side thereof is provided with a holding button, the outer side of the rotatable handgrip and the bottom of the holding button are respectively and oppositely formed with an arc-shaped convex part and an arc-shaped concave part, a pin rod of a shaft pin is allowed to pass a shaft hole formed on the arc-shaped convex part or the arc-shaped concave part and having a diameter greater than the pin rod then be inserted in a pin hole axially formed on the arc-shaped concave part or the arc-shaped convex part of the holding button, so the arc-shaped concave part or the arc-shaped convex part of the holding button is able to be moved along the arc-shaped convex part or the arc-shaped concave part of the rotatable handgrip, the up/down swinging angle generated during the inner side of the rotatable handgrip being rotated is able to be absorbed, thereby enabling the holding button to be constantly vertical to the rotatable handgrip.
The present invention will be apparent to those skilled in the art by reading the following detailed description of a preferred embodiment thereof, with reference to the attached drawings, in which:
a is a perspective exploded view illustrating the grinder according to the present invention;
