ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a utensil and, more particularly, to an improved kitchen utensil having an adjusting device so as to adjust a length thereof.
2. Brief Description of the Prior Art
Kitchen utensils involve many different types of forks, turners, lifters or spoons, each of the above mentioned kitchen utensils has a handle and a utility head fixedly connected to an end of the handle. However, the length of the whole utensil is unchanged so that it is often seen many kitchen utensils are equipped with many sizes in order to be used in different situations. Therefore, a kitchen has to leave a special room to keep these kitchen utensils. Even for a fork for example, a user has to buy more than one so as to have different lengths. In fact, some of the kitchen utensils are not used so often and they occupy a lot of space. This is troublesome for those who has a small kitchen.
The present invention intends to provide an improved kitchen utensil having a length adjusting device so as to adjust a length of the kitchen utensils according to users' needs.
SUMMARY OF THE INVENTION
In one aspect of the present invention, there is provided a kitchen utensil comprising a lower portion having at least two longitudinal first flanges extending upwardly from an upper side thereof and a tubular portion extending upwardly from the upper side of the lower portion so as to receive a spring and a ball therein. An upper portion has two longitudinal second flanges extending from an underside thereof and an aperture defined therethrough which is located between the two second flanges.
An elongated strip has a plurality of holes defined therethrough and a utility head formed to one of two ends thereof. The strip is disposed between the lower and the upper portions. An operation member is disposed between the upper portion and the strip, the operation member having a top extending from the aperture and a protrusion extending downwardly therefrom so as to extend through one of the holes and contact the ball. An arm extends from the operation member and has a tip so as to be inserted into another hole.
It is an object of the present invention to provide a kitchen utensil wherein a distance between a utility head and a handle is adjustable.
It is another object of the present invention to provide a kitchen utensil which utility head is replaceable.
Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
