Various embodiments of this invention relate, generally, to systems for cleaning devices; more particularly, to cleaning implement handle kits, which allow various cleaning implements and handles to be detachably attached to one another.
Conventional cleaning implement handles utilize a pole and implement attachment system in order to allow user to re-attachably connect cleaning implements to the pole. The related arts systems, however, suffer from several shortcomings and Various related art systems disclose such systems; for example: U.S. Pat. No. 1,483,435 to Hammer, U.S. Pat. No. 3,425,756, U.S. Pat. No. 4,466,377, U.S. Pat. No. 6,378,400 to Bogli, and U.S. Patent Application No. 2003/0135950 to Dove.
U.S. Pat. No. 1,483,435 to Hammer, for example, discloses a detachable handle that attaches to another implement by an aperture on the handle that engages with a fastener. Then, in order to remove Hammer's detachable handle, one loosens the fastener and releases the handle from the implement. In this manner, the handle may be added to and removed from other implements. The device, however, requires the use of additional tools, such as a screw driver or wrench in order to loosen the fastener, which may be undesirable in many circumstances.
Another such mechanism is disclosed by U.S. Pat. No. 3,425,756 to Hubbard. Hubbard's patent discloses a detachable extension handle that is also extensible. The extension handle uses a pin lock in order to connect the extension handle to an implement. The pin lock in Hubbard's device comprises a round symmetrical and generally cylindrically shaped button that is spring-loaded, such that when depressed, the button returns to its natural position. Like other pin locks, the button engages with an aperture in order to connect the extension handle to an implement. Hubbard improves upon other devices in the art by featuring a plurality of apertures at different distances along the implement. Thus, by selecting a given aperture, the user may select the desired length of the extension.
Like other pin lock mechanisms, however, the Hubbard's mechanism suffers from many shortcomings, making it undesirable to use in certain applications. First, in order to attach the extension handle to an implement, a user must depress the button, thereby requiring additional effort. The implement cannot be attached easily or with one hand. Also, in cases where the implement, such as a mop or paint brush, may be dirty or contaminated, it is often times undesirable to hold the implement because the dirt or contamination is transferred to the user's hands. Also, the circular shape of the pin lock is not conducive to easy attachment to and removal from the implement.
Another such mechanism is disclosed by U.S. Pat. No. 4,466,377 to Kolb et al. Kolb discloses a device for fastening handles to implements by a button activated locking insert. An extension is attached to a handle by, first, inserting the implement to an opening in the handle. Within the handle, a leaf spring engages with a hole in the implement in order to lock the handle onto the implement. The mechanism also features a push-button that is depressed from the outside of the handle in order to release the leaf spring and the implement from the handle.
A similar such mechanism is disclosed by U.S. Pat. No. 6,378,400 to Bogli. Bogli's patent discloses a detachable handle socket ratchet system that allows the user to change handles to suit the needs of the user. The coupling system, that attaches the handle to the ratchet, comprises a hinged and spring-loaded retaining pin at the handle that engages with a groove at the ratchet. The retaining pin disclosed by Bogli improves upon other related art systems by being generally sloped towards the distal end of the lever. In order to remove the handle from the ratchet, a button is pressed by the user, depressing the retaining pin from the groove, and allowing the handle to be removed.
Another such mechanism is disclosed by U.S. Patent Application No. 2003/0135950 to Dove. Dove's patent application discloses a mechanism for connecting a paint brush handle to an extension pole by a spring button device. Like the above patents, however, Dove fails to disclose a mechanism whereby the extension handle may easily be attached to the implement without the necessity of depressing the push-button. Further, like the above patents, Dove fails to disclose the use of an oval-shaped button, such that the extension is more easily attached to and removed from the implement.
In order to address the shortcomings of these and other related art systems, there remains a long felt need in the art for a combination handle and extension handle kit for cleaning implements, which allows various handles, extension handles, and cleaning implements to be easily attached and re-attached to one another.
Various embodiments of the invention are directed towards overcoming the shortcomings of the above and other related art systems by disclosing a combination cleaning implement handle and extension handle kit. Various embodiments of the invention comprise a kit with numerous parts that allow the cleaning implement handle to be variably attached and re-attached the cleaning implements.
Various embodiments of the invention comprise: one or more implement holders; a relatively short implement handle; and a relatively long implement handle that is telescoping and extendible.
Various embodiments of the invention further comprise an attachment system which may be used to attach the implement handles to one or more implement holders. In various embodiments of the invention, the attachment system comprises a pin lock system. The pin lock, in various embodiments of the invention, features a novel shape. First, the top side of the pin features a slope that angles toward the edge of the distal end of the extension handle. This sloped top configuration allows the pin lock mechanism to engage with the aperture of the implement handle without the need for the user to manually depress the pin. Also, the pin, in various embodiments of the invention, features a novel oval or rounded edge shape. The oval shaped pin allows the pin to engage with the aperture with a minimal effort by the user. Similarly, in various embodiments of the invention that use a generally rectangular-shaped pin that features rounded edges, the rounded edges allow the pin to smoothly, and relatively effortlessly, engage with the aperture. In this manner, the novel configuration of the pin allows the extension handle to be more easily coupled to the implement handle than other prior art devices.
The pin lock mechanism further features a spring mechanism that presses the pin outwards. In various embodiments of the invention, the spring mechanism comprises a pin that is located within the extension handle and serves to apply pressure on the pin upwards. The use of a novel shape for the pin and the spring allows the pin to engage with the aperture in order that the implement handle may be removably connected to the extension handle.
It remains within the contemplation of the invention that it to be used with varying types of cleaning implements. Implement handles of varying lengths, materials, and types remain within the contemplation of the invention. Telescoping handles of varying types also may be used with the various embodiments of the invention. Also, the principles of the invention may be practiced with various cleaning implements.
