Abstract
A socket device with an off-center slot for loosening and tightening connectors positioned in confined locations. The socket includes a socket body, a slot to allow a tube or pipe to pass there through and a nut retaining region. The nut retaining region positioned adjacent to a first face of the socket has a centerline that is offset from the centerline of the socket body. A socket driver port located in the opposing second face of the socket has a centerline that is offset from the centerline of the socket body but remains within the dimensions of the socket body. That arrangement allows socket rotation within a confined area with maximum possible mechanical advantage. The socket may have different receiving region configurations to accommodate different nut connector designs.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to sockets. More particularly, the present invention relates to sockets for use in loosening and tightening nuts and washers in difficult to reach locations. Still more particularly, the present invention relates to devices for loosening and tightening nuts and washers used to connect pipes and tubing to basin faucet connections.




2. Description of the Prior Art




In a variety of situations, it is a common problem for individuals seeking to connect or disconnect a coupling to gain access to such a coupling in a manner that enables reasonable loosening or tightening of the coupling. The coupling may be in a remote location or movement may be restricted by the particular surroundings. For example, a fitting associated with an engine may be in an awkward location with little lateral movement possible, or it may be adjacent to other relatively immovable objects. The individual must therefore have a very specialized tool to contact the fitting and rotate it. More often, the individual must use a relatively standard tool, such as a wrench, and go through a series of contortions to access the fitting and rotate it in a limited manner such as by making very short movements and resetting the tool on the fitting.




The situations in which an individual can find himself or herself in need of a specialized tool to gain access to a fitting, coupling or connection may be endless. One such situation that generated the conception of the present invention relates to the connection of supply and return pipes and tubes to the faucet of a basin or sink. That connection comprises one or more coupling nuts that removably join the supply and return pipes/tubes to the faucet mechanism. The connection is ordinarily located on the underside of the basin, where the space is confined and the tubes and pipes restrict the ability to move laterally. That confinement and restriction on lateral movement make difficult the use of a standard open-ended or box-end wrench to loosen or tighten the coupling nut. Moreover, the tube/pipe is substantially aligned on center with the center of the connecting device. That alignment prevents use of any inline device, such as a close-ended socket on a ratchet with extension, because the pipe/tube restricts access as well as rotational movement.




There are several limitations associated with devices that would otherwise be used for loosening and tightening connections in confined areas and with tube/pipe alignment restrictions. One such limitation is having the opening used to contact and retain the connector being centered on the body of the device. A device with an opening that is centered on the device body, such as an open-ended socket, will be adversely restricted by the alignment of the tube or pipe with the connecting nut. Another limitation is having the component of the device used to cause device rotation—such as a socket driver—centered on the body of the device. A device with such a restriction may also be adversely affected by the alignment of the tube or pipe with the connecting nut. Yet another limitation is having the component of the device used to cause rotation positioned adjacent to the body of the device. Placing the driver substantially away from the center of the body significantly reduces the mechanical advantage required to force connector rotation. A further undesired limitation is having a substantially long device body relative to the height of the connector. That limitation may cause binding of the device on the connector under any misalignment condition.




Therefore, what is needed is a device for loosening and tightening connections located in confined spaces. The device must include a body member for retaining the connector and designed to allow its rotation by a rotation-causing element such as a socket driver. The opening of the body member for retaining the connector is preferably not centered on the body. What is also needed is such a device designed to position the component that causes rotation of the body member off center from the center of the body member.




SUMMARY OF THE INVENTION




It is an object of the present invention to provide a socket for loosening and tightening connectors located in confined spaces. It is also an object of the present invention to provide such a socket having a body member with an off-center connector retention space and an off-center port for receiving a socket driver. It is therefore an object of the present invention to enable leveraged movement of a confined connector element with reduced impedance to that element caused by the positioning of tubes or pipes connected therewith.




These and other objects are achieved by the present invention, which is an improved socket. The socket is a socket body having a slot running its length and, in one face, a driver port for receiving a socket driver. The driver port is offset from the centerline of the socket body. The opposing face of the socket body and that portion of the slot adjacent to that face are configured to grab a connector nut to be loosened or tightened. Having a slot through the length of the socket allows a user to comfortably fit the socket around any tubing or piping that terminates in or passes through the nut to be loosened or tightened. Having the driver port off center of the body but still part of the socket body allows the user to comfortably manipulate the socket at a distance and with leverage. The opposing face of the socket may also include face slots spaced to accommodate the wings of a plastic nut should one have to be loosened or tightened.




A single socket body of the present invention may be configured to accept connector nuts of varied sizes. That capability may be achieved by forming a portion of the slotted space of the socket body with a plurality of stepped regions varying in dimensions that comform to the dimensions of connector nut sizes in use. Alternatively, the socket body may be configured with only one nut-retaining space configuration. A plurality of socket bodies each with a different slot space configuration may be assembled in a kit to allow a user to employ separate sockets for differing nut dimensions.




The nut-receiving space is established by forming in the socket body an annulus, the center of which is off the centerline of the socket body. The socket body may be cylindrical or polygonal. A portion of the circumference of the wall of the annulus is removed through the entire length and through the thinner portion of the annulus wall to form a slot therein. The width of the slot is selectable but of a size sufficient to allow a pipe or tube to pass there through. A nut capturing region is established adjacent to a first face of the socket body. The nut capturing region is formed in the thicker portion of the annulus wall adjacent to that first face. The opposing face of the socket body includes a driver port for receiving a socket driver. The driver port is located in the thicker portion of the annulus wall.




The present invention is a socket with an off-center slot at one end thereof and an off-center socket driver port in an opposing end thereof. That design enables the user to loosen and tighten connectors in confined spaces by permitting access and maintaining mechanical leverage. These and other advantages of the invention will become apparent upon review of the following detailed description, the accompanying drawings and the appended claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




As illustrated in

FIG. 1

, the present invention is an improved socket


10


having a first face


11


and an opposing second face


12


. In the figure, the socket


10


is shown in use as a device to loosen and tighten nuts employed to secure supply water to the faucets of a basin. However, it is to be understood that the socket


10


may be employed to loosen and tighten connectors in non-plumbing applications. With continuing reference to

FIG. 1

, the socket


10


is shown in position on the underside of a basin enclosure


13


. The socket


10


may be rotated by a socket driver, such as a ratchet


14


. An extension


15


may be used to space the ratchet


14


from the socket


10


. The socket


10


includes a socket driver port


16


in the opposing second face


12


for receiving and removably retaining therein the extension


15


or the ratchet


14


.




The socket


10


includes a socket body with a receiving slot


17


through the socket body. The receiving slot


17


permits a supply tube


18


to pass there through without inhibiting the interior of the socket body adjacent to the first face


11


from contacting one or more nuts associated with securing the supply tube


18


to a faucet stem


19


of a faucet


20


at the underside of the basin enclosure


13


. In particular and as to be described with respect to the other figures, the interior of the socket body is configured to: 1) capture and rotate a supply tube nut


21


associated with securing the supply tube


18


to the faucet stem


19


; 2) capture and rotate a faucet stem retaining nut


22


associated with securing the faucet


20


to the underside of the basin enclosure


13


; or 3) a combination of the two. Thus, the socket


10


may be employed to cause rotation of the faucet stem retaining nut


22


and/or the supply tube nut


21


without interference from the supply tube


18


and within the confined space associated with an area such as the basin enclosure


13


. The arrangement of the interior of the socket


10


including the receiving slot


17


and the position of the socket driver port


16


as described herein enable that capability.




As illustrated in

FIGS. 2 and 3

, a first embodiment of a socket


30


of the present invention includes first face


31


, an opposing second face


32


, a receiving slot


33


, a receiving region


34


for receiving and capturing therein a nut to be loosened or tightened, and a plurality of wing slots


35


. The opposing second face


32


includes a socket driver port that is designed substantially the same way for all of the socket embodiments described with respect to

FIGS. 2-3

and


5


-


10


, and will be described with reference to FIG.


4


. The receiving slot


33


extends from the first face


31


through to the second face


32


. It includes an entry


37


through which a supply tube may pass when setting the socket


30


in position, and a tube positioning region


38


in which the tube remains while the socket


30


is being rotated. Of course, the socket


30


may be rotated without a tube in place under the basin. For example, when only the faucet stem retention nut


22


is being rotated.




With continuing reference to

FIGS. 2 and 3

, the receiving region


34


is adjacent to the first face


31


of the socket


30


and includes a step


36


that acts as a stop against which the face of the nut rests during socket rotation. The receiving region


34


is configured in a polygonal configuration for retaining therein nuts of polygonal shape. The receiving region


34


includes a receiving region centerline


39


that is offset from a socket body centerline


40


. In that way, the nut may be retained in the receiving region


34


while the socket driver port remains within the dimensions of the socket body. That ensures maximum mechanical advantage when using the socket


30


without compromising device flexibility in confined spaces. In effect, the socket


30


is an offset annulus, with the relatively thinner portion of the wall of the socket body being the location for the receiving slot


33


and the receiving region


34


.




In the embodiment of the present invention shown in

FIGS. 2 and 3

, the first face


31


includes the plurality of wing slots


35


for retaining therein the wings of a nut that may be a plastic faucet stem retention nut of the type having wings for ease of rotation. A multipurpose version of the socket of the present invention would include such wing slots


35


in the event the user must loosen or tighten such plastic nuts. Alternatively, a version of the socket as shown herein does not include such wing slots


35


.




As illustrated in

FIG. 4

, the opposing second face


12


includes the socket driver port


16


for receiving a socket driver or other device suitable for causing rotation of any of the opposing face socket configurations of the present invention. The port


16


includes a port centerline


41


that is offline from the socket body centerline


40


. That positioning permits formation and positioning of the slot


17


for retaining a supply tube and for location of the nut receiving region without placing the socket driver port


16


outside of the dimensions or footprint of the socket body itself. That allows nut retention within the socket body without reducing significantly the mechanical advantage otherwise achieved by positioning the rotational device directly inline with the socket body centerline


40


. Prior socketed wrench devices having the rotational component outside of the dimensions or footprint of the socket suffer loss of rotational leverage.




As illustrated in

FIGS. 5 and 6

, a second embodiment of a socket


50


of the present invention includes first face


51


, an opposing second face


52


, a receiving slot


53


, a receiving region


54


for receiving and capturing therein a nut to be loosened or tightened, and a plurality of wing slots


55


. The opposing second face


52


includes a socket driver port that is designed substantially the same way as illustrated in FIG.


4


. The receiving slot


53


extends from the first face


51


through to the second face


52


. It includes an entry


56


through which a supply tube may pass when setting the socket


50


in position, and a tube positioning region


57


in which the tube remains while the socket


50


is being rotated. Of course, the socket


50


may be rotated without a tube in place under the basin. For example, when only the faucet stem retention nut


22


is being rotated.




With continuing reference to

FIGS. 5 and 6

, the receiving region


54


is adjacent to the first face


51


of the socket


50


and includes a first step


58


that acts as a stop against which the face of a nut of first dimensions rests during socket rotation. The receiving region


54


includes a second step


59


that acts as a stop against which the face of a nut of second dimensions smaller than the dimensions of the nut associated with the first step


58


rests during socket rotation. In this way, the socket


50


alone may be employed to loosen or tighten a plurality of nuts of differing dimensions. Of course, additional steps may be added if additional nut dimensions are to be covered. The receiving region


54


is configured in a polygonal configuration for retaining therein nuts of polygonal shape. Alternatively, the first step


58


may be of a rounded configuration to retain thereon the head of a rounded plastic nut having wings. The receiving region


54


includes a receiving region centerline


60


that is offset from a socket body centerline


61


. In that way, the nut may be retained in the receiving region


54


while the socket driver port remains within the dimensions of the socket body. That ensures maximum mechanical advantage when using the socket


50


without compromising device flexibility in confined spaces. In effect, the socket


50


is an offset annulus, with the relatively thinner portion of the wall of the socket body being the location for the receiving slot


53


and the receiving region


54


.




In the embodiment of the present invention shown in

FIGS. 5 and 6

, the first face


51


includes the plurality of wing slots


55


for retaining therein the wings of a nut that may be a plastic faucet stem retention nut of the type having wings for ease of rotation. A multipurpose version of the socket of the present invention would include such wing slots


55


in the event the user must loosen or tighten such plastic nuts. Alternatively, a version of the socket as shown herein does not include such wing slots


55


.

71


, an opposing second face


72


, a receiving slot


73


and a receiving region


74


for receiving and capturing therein a nut to be loosened or tightened. The opposing second face


72


includes a socket driver port that is designed substantially the same way as illustrated in FIG.


4


. The receiving slot


73


extends from the first face


71


through to the second face


72


. It includes an entry


75


through which a supply tube may pass when setting the socket


70


in position, and a tube positioning region


76


in which the tube remains while the socket


70


is being rotated. Of course, the socket


70


may be rotated without a tube in place under the basin. For example, when only the faucet stem retention nut


22


is being rotated.




With continuing reference to

FIGS. 7 and 8

, the receiving region


74


is adjacent to the first face


71


of the socket


70


and includes a first step


77


that acts as a stop against which the face of a nut of first dimensions rests during socket rotation. The receiving region


74


includes a second step


78


that acts as a stop against which the face of a nut of second dimensions smaller than the dimensions of the nut associated with the first step


77


rests during socket rotation. In this way, the socket


70


alone may be employed to loosen or tighten a plurality of nuts of differing dimensions. Of course, additional steps may be added if additional nut dimensions are to be covered. The receiving region


74


is configured in a polygonal configuration for retaining therein nuts of polygonal shape. The receiving region


74


includes a receiving region centerline


79


that is offset from a socket body centerline


80


. In that way, the nut may be retained in the receiving region


74


while the socket driver port remains within the dimensions of the socket body. That ensures maximum mechanical advantage when using the socket


70


without compromising device flexibility in confined spaces. In effect, the socket


70


is an offset annulus, with the relatively thinner portion of the wall of the socket body being the location for the receiving slot


73


and the receiving region


74


.
