Push-flex attachment
A flexible attachment mechanism used in conjunction with a push broom or floor squeegee having a handle and a broom head or squeegee blade to provide a flexible attachment mechanism at the junction where the broom head or squeegee blade handle is connected to the broom head or squeegee blade support frame. The flexible attachment mechanism allows the broom head or squeegee blade to flex up and down causing the flexible attachment mechanism to be pre-loaded when pushing with the handle and upon releasing the downward movement during a normal sweeping action, the pre-loaded flexible attachment mechanism springs up, which in turn causes the broom head or squeegee blade to spring upwardly to kick the debris further away from the broom head or squeegee blade holder. Furthermore, the new innovation allows heavy equipment to run over the handle and/or cleaning head and flex thus reduce handle and/or cleaning head damage.
1. Background of the Invention
The present invention relates to a cleaning or a sweeping apparatus and in particular for brooms and floor squeegees or applications where material is being removed by an apparatus. The present invention further relates to a flexible insert apparatus which can enhance the ease of use and cleaning capability of brooms. In particular, the present invention relates to a cleaning apparatus or the like having the capability of up and down flexing for providing improved sweeping action and reduce damage when being run over by heavy objects along with flexing laterally when hitting objects reducing handle breakage.
2. Description of Prior Art
The standard brush broom has two primary components. The first component is the head that comprises a rectangular piece of material usually made of wood that supports therein a multiplicity of bristles of fibers that extend transversely to the head. The second primary component of the brush broom is the handle which is usually a cylindrical pole that is rigidly although sometimes removable affixed to the top of the head in the manner which permits the brush broom to be pushed and pulled by the exertion of a force on the handle.
One significant problem with brush brooms is longer length bristles are needed to create sufficient flick action to push the debris when sweeping, also they are usually laid down on the floor thus making the broom venerable to being run over by vehicles or walked over causing either or the handle and brush block to break. Also the broom handle can break when used in confined spaces is the rigid nature of the connection between the handle and head causes difficulty in sweeping adjacent, corners, tables, chairs and other areas where obstacles are placed on the floor. The edge of the broom head it's the obstacle straight on and then it is necessary to stop the sweeping action and reorient the push broom to avoid or go around the obstacle. In addition, if the force of the sweeping action is sufficiently strong, the head—on impact of the brush broom could cause damage to the object being hit, inflict injury to the operator or break the push broom handle and/or brush block. The reason for the damage is due to the moment between the handle and broom head length which causes a fulcrum effect. To overcome this problem prior art has been developed to allow the brush broom to be flexible at the joint between the brush broom and the pole handle. However, to effectively have a workable flexible brush broom, the flex mechanism needs to be somewhat rectangular in shape along the longitudinal axis to retain sufficient rigidity yet have enough flexibility to allow an up and down movement in the longitudinal axis while being flexible in the lateral axis.
Patent on mechanisms or attachments that allow for a flexible joint between the brush broom handle are simply cylindrical in shape thus allowing the connector to be threaded into a broom block. Such is the case of polymeric or polyurethane adapter U.S. Pat. Nos. 4,722,634 and 5,333,345. Since all known prior flexible adaptors are made to flex laterally to absorb impacts when hitting stationary objects. The present innovation optimizes the design of the flexible connector to flex up and down thus rendering it almost unbreakable when being run over by large vehicles that causes most of the broom handle block damage. Also, the flexible attachment mechanism allows the broom head to flex up and down causing the flexible attachment mechanism to be pre-loaded when pushing with the broom handle and upon releasing the downward movement during a normal seeping action, the pre-loaded flexible attachment mechanism springs up, which in turn causes the broom head to spring upwardly to kick the debris further away from the broom head.
Therefore, a significant need exists to improve upon the previous prior art patents and to provide a flexible attachment mechanism that can be adapted for controlling the up and down flexing of the cleaning head to push debris further reducing the bristle length of the bristles and lateral flexing to provide an improved sweeping action and to eliminate breakage when heavy loads, such as vehicles, are applied on top of the broom while being laid down on the floor.
SUMMARY OF THE PRESENT INVENTIONThe present invention is a mechanism that is affixed at the location between the brush handle and the head of the brush broom to provide a flexible member at the junction where the handle is attached to the head. Through use of the flexible member and the arc designed shape, the handle maintains sufficient rigidity in the direction in which it is moved when pushed lightly but when placing a sufficient load on the handle the attachment mechanism allows the broom head to flex up and down causing the flexible attachment mechanism to be pre-loaded when pushing the broom handle and upon releasing the downward movement during a normal sweeping action, the pre-loaded flexible attachment mechanism springs up, which in turn causes the broom head to spring upwardly to kick debris further way from the broom head thus shorter bristles can be used reducing cost. Through use of the flexible member the attachment is adequately flexible in the lateral direction. Therefore, when the brush broom comes in contact with a stationary object, the broom will flex and have sufficient enough movement to reduce hand injury to the operator and/or damage to the broom handle.
It is an object of the present invention to provide a flexible attachment mechanism which can be adapted for connecting a push broom head to a push broom and or floor squeegee handle and thereby forms a complete cleaning apparatus. It is an additional object of the present invention to provide a flexible attachment mechanism that can be adapted for controlling the up and down flexing of the cleaning head to provide an improved sweeping action and eliminate breakage when heavy loads are applied on top of the broom while being laid down on the floor.
Further novel features and other objects of the present invention will become apparent from the following detailed description, discussion and the appended claim, taken in conjunction with the drawings.
Referring particularly to the drawings for the purpose of illustration only and not limitation, there is illustrated:
Although specific embodiments of the invention will now be described with reference the drawings, it should be understood that such embodiments are by way of example only and merely illustrative of but a small number of the many possible specific embodiments which can represent applications of the principles of the invention. Various changes and modifications obvious to one skilled in the art to which the invention pertains are deemed to be within the spirit, scope and contemplation of the invention as further defined in the appended claims.
In the embodiment illustrated in
The flexible apparatus 10 is made of a flexible elastomeric rubber like material like polyurethane. The handle 120 is either press fit, screwed or riveted or any other means attached into the apparatus housing 140. When press fit, the flexible elastomer material expands and thus requires the hole diameter in the apparatus housing 140 to be a minimum 0.050″ less in diameter than the diameter of handle 120.
In the preferred embodiment, the insert member 10 is made of any flexible substance with memory such as rubber, plastic, titanium, polyurethane and polyvinyl. It is also within the spirit and scope of the present invention for the attachment to be made of flexible but strong plastic such as Mylar, polyethylene or any other flexible material exhibiting the required memory characteristics.
In the embodiment illustrated in
In the preferred embodiment, the insert member 10 is made of any flexible substance with memory such as rubber, plastic, titanium, polyurethane, polyvinyl. It is also within the spirit and scope of the present invention for the attachment to be made of flexible but strong plastic such as mylar, polypropylene or any other flexible material exhibiting the required characteristics.
The preferred embodiment of the present invention is shown in use on
In order to facilitate the ease of motion for the sweeper, the longitudinal section 14 (and flexible member 18) is offset at an angle relative to its respective lateral sections 26 and 16. As illustrated in
An alternate embodiment for the base of the attachment is illustrated in
Defined broadly, the present invention is a flexible insert member with and recess cavities to allow flexing around the y and x axis that is made from a one piece unitary molded flexible material that is attached to the end of a brush broom handle and attached to the head of the brush broom without stop limits that is attached to thereby provide a controlled flexible connection between the handle and head of the brush broom, the flexible insert being rigid in the longitudinal direction to permit the handle to cause the broom head to move back and forth yet flex along longitudinal x-axis in order for the broom head and handle to be flat with no arc when heavy equipment or vehicles weight is applied onto the handle and or brush broom. To allow for sufficient flexing motion the distance between the bottom side of the recess cavity 364 and lower base mount positions 26 and 16 as shown in
Therefore, through use of the present inversion, a flexible sweeper can be manufactured that is economical and durable and thus allow a person doing the sweeping to sweep liberally and freely without worry of nicking or denting other objects along with reducing hand injury due to sudden broom impact. At the same time, the brush broom has the rigidity to push and pull large loads without flexing beyond the predetermined degree via the stop limits and allow heavy equipment to run over the broom without damage. The life of the broom handle and broom brush is also increased.
Referring to
The flexible attachment mechanism 210 is molded from a unitary elastomer material and includes an inclined longitudinal section 214, a lateral mounting section 216 and an arcuate connecting section 218 (see
Referring to
In order to facilitate the ease of motion for the user, the longitudinal section 214 and the flexible connecting section 218 is offset at an angle of approximately 45 degrees, preferably a range between 15 degrees to 80 degrees can be used.
Referring to
The flexible attachment mechanism 210 allows the broom head 202 to move in a downward motion which causes the mechanism to be pre-loaded when a user pushes down on the broom handle 204 and upon releasing the downward pressure during a normal sweeping action, the pre-loaded flexible attachment mechanism 210 will spring up the broom head 202 causing the debris in front of the broom head to be lifted up and pushed further away from the broom head. The rectangular shaped connecting section 218 is wide enough approximately between 0.5″-12″ to allow for a controlled spring action and not cause excessive wobble effect of the broom head. The stop limit member 260 of the flexible attachment mechanism 210 controls the amount of flexing in the downward direction to ensure that the broom head 202 moves approximately 75 degrees when the user pushes down on the broom handle 204. If the downward flexing is not controlled, the broom head will flex too far causing the bristles to not make sufficient contact with the floor and debris being pushed. The limit stop member 260 engages with the rear aft end of the broom head 262, thereby stopping any further movement of the flexible attachment mechanism 210. Also, the downward pre-loaded flexing action of the flexible attachment member to push the debris will allow the length of the bristles to not be as long since the attachment will enhance the flicking action thus is a cost savings.
The present invention conforms to conventional forms of manufacture or any other conventional way known to one skilled in the art, and is of simple construction and is easy to use. The flexible attachment mechanism 210 can be made from several materials. The manufacturing process which could accommodate the construction of the flexible attachment mechanism may be injection, thermoform, etc. or other molding processes. By way of example, the flexible attachment mechanism 210 can be made of any flexible substance with memory such as rubber, plastic, titanium, santoprene, acetal, polyurethane, polypropylene or any other flexible material exhibiting the required memory characteristics.
Define in detail, the present invention is a floor squeegee or push broom, comprising: (a) an elongated laterally disposed broom head having a top surface and a bottom cleaning surface, the bottom cleaning surface having plurity of bristles or squeegee blade extending downwardly therefore; (b) a unitary flexible attachment mechanism having amounting section, an inclined longitudinal section, and a flexible connecting section integrally connecting the mounting section and the longitudinal section together, the mounting section centrally affixed to the top surface of the broom head such that the longitudinal section extends upwardly and outwardly to form an angle relative to the mounting section, the longitudinal section having an axial bore with an open end; (c) an elongated broom handle having one end press-fitting from the open end and secured with the axial bore of the longitudinal section of the flexible attachment mechanism; (d) the flexible connecting section having a pair of recesses located on opposite sides and extending pad and a lower stop limit pad, where the upper engagement pad and its respective lower stop limit pad form a predetermined gap for allowing lateral flexing of the longitudinal section and the broom handle; and (e) a downward stop limit member that engageable with a rear aft end of the broom head, where the downward stop limit member controls the amount of downward flexing of the connecting and longitudinal sections in the downward direction: (f) whereby the attachment mechanism is pre-loaded when a user pushes down on the broom handle causing the connecting and longitudinal sections to flex downward and upon releasing the downward pressure during a normal sweeping action, the pre-loaded flexible attachment mechanism springs up the broom head causing the debris in front of the broom head to be lifted up and pushed further away from the broom head.
