Description
Priority
This application claims the benefit of U.S. patent application No. 15/208,901 filed on 7/13/2016.
Technical Field
The present application relates to, but is not limited to, retractable wall-mounted electrical plugs for charging communication devices.
Background
Portable handheld communication devices are powered by batteries whose power or charge is depleted over time due to the use of the batteries by the user. The handheld device has an access port or "jack" for receiving a USB (universal serial bus) plug. The insulated power cord has a USB plug at one end for connection to a port of the handheld device and a conventional wall plug at its other end for connection to a conventional wall outlet of a residence.
While such an arrangement appears convenient and useful, there are problems typically associated with conventional power cords, as a user of such a cord may wish to move the cord to other locations, such as in different rooms of a house or from one house to another, etc., or to a vehicle. As a result, the rechargeable power cord may be placed in a place that is not remembered at one time and is temporarily or permanently "lost" or unavailable to its owner. While this problem can be solved by keeping the power cord plugged into a single power outlet (outlet) and never moving it, there may be exceptions to trying to keep the power cord in a single location.
A lost power cord is likely to cause significant frustration to owners and other users of the power cord, and in many cases, the owner of the lost power cord may purchase an alternative power cord.
Another undesirable feature of the above-described power cord is that the insulated power cord typically has a length of about two feet and when the cord is not connected to a communication device, it extends out of its wall plug onto a counter, desktop, or other horizontal surface and presents an undesirable messy appearance.
For these and other reasons, it would be desirable to have a "docking station" for a communication power cord that is neat in appearance, in a fixed position, and conveniently used for the purpose of charging handheld communication devices and other devices having a plug receptacle for recharging.
Disclosure of Invention
Briefly, the present invention relates to a retractable wall-mounted electrical plug (retractable wall-mounted plug) for charging a battery of a communication device, such as a handheld communication device. Typically, an open face support box (open face support box) is provided for installation in the interior of a hollow wall of a building structure with its opening facing a room of the building structure. The panel is mounted to and closes the support box opening around the support box opening. The panel includes an outer surface that faces away from the support box and a back surface of the panel is exposed to an interior of the support box.
An outer surface of the panel defines a plug recess, and the electrical plug is sized and shaped to telescopically (telescopically) fit into the plug recess. The wire opening extends from the plug recess of the panel to the interior of the support box, provides a small passage between the outside and the inside of the panel, and extends into the support box.
The insulated electrical conductor wire includes an outer end portion connected to the plug and an intermediate portion extending between and through the wire opening of the plug recess and into the support box. The inner end of the wire in the support box is connected to a source of current.
A spring, such as a coil tension spring, is mounted between the interior of the support box and the inner end of the wire and is configured to bias the wire through the wire opening of the panel and into the support box. This causes the plug to be pushed toward the wall plate and into the plug recess of the wall plate to support the plug and insulated electrical conductor wire in an accessible, convenient and visually uncluttered configuration.
The electrical plug includes a plug main body, electrical contacts extending in a first direction away from the plug main body, finger grips extending from the plug main body in a direction orthogonal to the first direction of the electrical contacts, and insulated wires extending from the plug main body in a direction opposite the finger grips. The plug recess formed in the outer surface of the faceplate is configured to be compatible with the shape of the retractable electrical plug such that when the plug is inserted into the recess, the plug body and the electrical contacts may be received in and supported in the recess of the faceplate, with the electrical contacts thereof being shielded from inadvertent engagement by foreign objects.
When the plug is seated in the recess of the panel, the finger grip of the plug may extend from the plug support box in a direction away from the panel, preferably extending beyond the surface of the panel, and shaped to be grasped by the fingers of a user so that the user may grasp the plug and gently pull the plug away from the wall plate. This withdraws the plug from the panel and pulls the adjacent end of the insulated electrical conductor wire with the plug from the interior of the plug support box. This may also allow for flexible use of the communication device when the plug is connected to the communication device, and also allow for the communication device to be placed on a table surface or other horizontal surface adjacent the panel when the communication device is being charged.
When the communication device has been recharged and is ready for further use, the plug can be removed from the socket of the communication device and the spring behind the faceplate pulls the cord and thus pushes the plug back towards its plug recess formed in the outer surface of the faceplate.
This safely stores the electrical conductors of the plug out of the way and is ready for reuse.
The panel prevents the plug from deteriorating due to other objects and moisture, and the size of the opening through the material of the panel from the recess is so small that moisture or other contaminants will not be able to pass through the panel opening to the interior of the wall box.
Optionally, the electrical plug may also include other items, such as typical power ports for conventional electrical products (e.g., lamps and other devices that require continuous charging).
It is therefore an object of the present invention to provide a retractable electrical plug to be mounted in a hollow wall structure or the like for charging a portable communication device which is battery-charging.
Another object is to maintain a retractable charging plug in a retracted position and which includes an extendable and retractable plug for charging a communication device and which is easy to use and then stored in a safe state for later use.

Fig. 2 is a perspective view similar to fig. 1, but showing how a plug can be removed from the plug recess of the wall plate and inserted into a port of a communication device.
Fig. 3 and 4 are expanded views of the internal components of a retractable wall-mounted electrical plug.
Detailed Description
Referring now in more detail to the drawings in which like reference numerals refer to like parts throughout the several views, fig. 1 and 2 show a conventional wall-support box fitted into a hollow wall structure, a plug-support box 14 telescopically supportable by the wall-support box, and a panel 15 mounted to the plug-support box. If desired, a conventional plug and receptacle opening 16 may be formed through the panel outer surface 18 for alignment with a conventional jack (not shown).
As best shown in fig. 2, a plug recess 20 is formed in the panel 15, and a wire opening 27 extends from the recess 20, through the panel, and into the interior of the plug support box 14. The electrical plug 22 is sized and shaped to fit in the recess 20. The electrical plug 22 includes a plug body 24 and electrical contacts 28 thereof, the electrical contacts 28 extending from the plug body. The plug body 24 and the electrical contacts 28 are sized and shaped to fit telescopically within the plug recess 20 of the panel 15.
The enlarged finger grips 30 extend from the plug body at an angle, preferably a right angle, to the electrical contacts 28. This allows the enlarged finger grips 30 to project from the surface of the panel 15 when the plug body 24 and the electrical contacts 28 are inserted into the recess 20 for easy gripping by the fingers of a person, such as the fingers 32 and 33 of fig. 2.
The enlarged finger grips 30 project laterally around the stem (stem)23 so that the stem is positioned between the enlarged finger grips 30 and the plug body 24 and allows the electrical plug 22 to be easily pulled from the plug recess 20.
When the plug 22 has been used to charge an electrical communication device (electrical communication device) such as the product shown at 35 in figure 2, it may be pulled out and removed from the port 51 of the device 35 and then returned to its plug recess 20 in the panel where it is protected within the plug recess with the enlarged finger grips protruding out of the plane of the planar surface of the panel. When the plug is returned to its plug recess, the electrical wires 26 and their openings 27 are substantially covered by the plug 22, and the insulated electrical conductor wires 26 substantially fill the openings 27 so as to impede or prevent moisture transmission through the panel 15.
As shown in phantom in fig. 2, a magnet 37 is mounted to the inner surface of the panel 15. When the electrical plug 22 is inserted into its plug recess 20, the magnet exerts a magnetic force that tends to attract the metal of the plug main body 24 to its "nested" position within the plug recess 20, thereby ensuring that it will be possible to avoid the plug main body 24 being inadvertently removed from its plug recess.
A spring (not shown in fig. 1 and 2) is mounted in the plug support box 14 which applies a force to the insulated electrical conductor 26 to urge the electrical plug 22 towards its plug recess 20.
As shown in fig. 3 and 4, the plug support box 14 includes a support rod 46, the support rod 46 supporting a reel (reel)40, the reel 40 being spring biased and which retracts the insulated electrical conductor wire 26. A circular electrical conductor strip 41 is mounted to the spool 40 and makes contact with the conductor strip to impart current to the conductor strip. The electrical conductor wires 26 are also connected to the conductor strips 41 so that the current is transmitted through the wires 26 to the plug 22.
The gear 43, ratchet arm (ratchet arm)44 and disk 45 are mounted to the spool 40 on one side of the spool in a conventional manner with the conductor strip 41 on the opposite side of the spool 40. These items are rotatably mounted on the rod 46. The support web 48 of fig. 4 is configured for supporting the elements of fig. 3 by conventional hangers (hand loops) that are connected to the wall structure of the residence to which the electrical plug assembly is mounted.
Other prior art spring and spool configurations may be used as desired.
When the retractable wall-mounted electrical plug is attached to a conventional hollow wall structure, the insulated electrical conductor wire 26 will be live and ready to recharge the battery of a communications device such as the device 35 of fig. 2. The electrical plug 22 will be retained in its plug recess 20 of the panel 15 until it is used to recharge the battery of the device 35.
As shown in fig. 2, the operator will grasp the enlarged finger grips 30 of the plug main body 24 with his/her fingers 32 and 33 to pull the plug main body away from the plug recess 20 on the panel 15 and pull the plug main body out of the plug recess 20 on the panel 15. This gradually pulls the insulated conductor wire 26 from its spool 40 and through the opening 27 and plug recess 20 so that the plug 22 can reach the communication device 35. The operator inserts the electrical contacts 28 of the plug body 24 into the port 51 of the communication device to make contact with the battery of the communication device to recharge the battery.
When the battery has been recharged, the electrical plug 22 can be removed by applying a human finger to the protruding portion of the plug body 24 to withdraw the electrical contacts 28 of the plug from the communication device, and then allowing the spring of the spool to push the conductor wires toward the plug recess, through the wire opening 27 of the panel and into the plug support box 14 until the plug 22 nests in the plug recess or port 20 and the wires 26 retract into the plug support box.
Although preferred embodiments of the present invention have been disclosed in detail herein, variations and modifications may be made to the disclosed embodiments without departing from the spirit and scope of the invention as set forth in the following claims.
