Adjustable bristle broom

Abstract

The adjustable bristle broom is a broom of which the bristles (32) are vertically, up or down, adjustable. The broom is comprised of an elongated handle (12) that connects the bristle housing (16), the connection is made through an upper lip (26) and a lower lip (28) located at the bottom of broom handle (12). The lips of the broom handle snap fits with the semi-circular lip (30) located within the top of the bristle housing (16). The adjustment means is a spring loaded push button (20) that works in accordance with the broom handle (12) and bristle rod (14). When the bristles (32) are adjusted outward from the bristle housing (16), bristle tensile strength decreases. When the bristles (32) located within the bristle housing (16) are shortened or adjusted inward, the bristle tensile strength increases allowing for a broom that can be used on several different surfaces indoors and outdoors.

BACKGROUND OF THE INVENTION—FIELD OF THE INVENTION

This device relates to sweep brooms, those of which are commonly used in households.

BACKGROUND OF THE INVENTION

Brooms have been in use for thousands of years. In todays modern society the most common broom is the sweep broom used in a majority of households through out the modern world. In certain factory settings the most common broom in use is the push broom made in various sizes with varying bristle tensile strengths as well as varying bristle lengths. The push brooms are used to push debris rather than sweep debris as is the function of the sweep broom commonly used in households

In certain office complex settings a certain type of broom that is often in use is the dust broom, whose primary function is to keep dust and other debris off of the none carpeted areas of the office complex floors. Another type of broom in use is named the hand held broom, which is used to facilitate the placement of debris into a dust pan. This type of broom is often found in the industrial or office building settings.

All of the brooms mentioned are made from a variety of materials such as from plastic, plastic type material such as teflon, wood, light weight metals and perhaps in the future as technology advances, materials yet to be formulated or discovered.

1. Discussion of Prior Art

Of the several types of brooms mentioned one thing is common that is that the tensile strengths are different in all of the brooms mentioned. Besides the tensile strength of brooms, in some brooms or devices having bristles; varying tensile strengths are reached through an adjustment of the device its self; such as U.S. Pat. No. 4,149,293 Raaf et al, U.S. Pat. No. 5,142,726 Mann., and U.S. Pat. No. 6,202,248 B1 Faires. These patents show tooth brushes that obtain varying tensile strengths through or by adjustment of the tooth brush its self. U.S. Pat. No. 6,076,221 Bradshaw and patent application No. US 2003/0031510 A1 Suriano show brooms with adjustable bristles although, these brooms are not trying to achieve a different tensile strength. U.S. Pat. No. 5,027,838 Iaia et al shows a cosmetic applicator with varying bristle lengths, achieved through the adjustment of the device its self.

OBJECT AND ADVANTAGES

It is the object of the device referred to as the adjustable bristle broom to provide one single broom that has varying bristle tensile strengths; so that more than one sweeping task can be accomplished. With the adjustable broom in one setting the sweeping of a varnished hard wood floor can be accomplished. With the adjustable broom in a different setting the clean up of a less than smooth surface, such as a patio walk way is possible. Of the brooms mentioned earlier the clean up of different surfaces can be accomplished, but not with out using more than one broom. The advantage is that clean up of a vast area can be accomplished in less time using the adjustable bristle broom, another advantage is that a person can go from an indoor to outdoor sweeping task using only one broom. One more advantage of the adjustable bristle broom is that the perfect setting can be made concerning the task at hand; such as finding the perfect setting for sweeping a pound of sugar off the floor, or finding the perfect setting for sweeping moist sand off of a stone driveway.

Further objects and advantages of the device referred to as the adjustable bristle broom will become apparent from a consideration of the drawings and ensuing description.

SUMMARY

The adjustable bristle broom is a broom that has vertically adjustable, up or down, bristles. Allowing for different tensile strengths of the bristles. When the bristles of the adjustable bristle broom, located with in the bristle housing are adjusted vertically upward, there is a minimal amount of bristles protruding from the bristle housing, allowing for the broom to have a stronger bristle tensile strength. When the bristles of the broom are adjusted downward or outward there is a longer length of bristles coming from the bristle housing allowing for a broom with a softer bristle tensile strength.
