In the drawings:
The guest connection assembly 10 comprises a grommet 12 and a grommet cap 14 coupled with an extension cord 16. As used herein, the term extension cord is used to refer to any cord capable of receiving electrical power and/or data from a source and transmitting it over a predetermined distance for delivery to an electronic device which is interconnected with the extension cord.
The guest connection assembly 10 of
The grommet 12 includes a generally circular upper edge 28 coupled with a generally circular lower edge 30 by a sleeve 32 such that the grommet 12 has a generally cylindrical shape defining a hollow channel 34. The grommet 12 can further include a lip 36 extending outwardly from the upper edge 28 for limiting the movement of the grommet 12 within a grommet hole (not shown) in which the grommet 12 is installed. While the grommet 12 is illustrated as having a generally circular shape, the grommet 12 can have any regular or irregular shape. For example, the grommet 12 can have an oval or rectangular shape. An inner dimension of the channel 34 can be selected such that the second end 22 of the extension cord 16 can be received by and pass through the channel 34.
The sleeve 32 can be formed so as to be retained within the grommet hole in which the grommet 12 is mounted. For example, as illustrated in
While the grommet 12 is described as being press-fit into the grommet hole, it is within the scope of the invention for the grommet 12 to be mounted within the grommet hole using any suitable mechanical or non-mechanical connectors, such as screws or adhesives, for example. The grommet 12 can be made from any suitable polymeric or metal material.
Referring now to
The diameter of the rim 46 of the grommet cap 14 is sized such that the rim 46 abuts the lip 36 of the grommet 12 when the grommet cap 14 is mounted to the grommet 12, as illustrated in
It is also within the scope of the invention for the guest connection assembly 10 to not include a seal 52. In another example, the maximum outer diameter of the circumferential wall 42 may be selected so as to frictionally engage the inner wall 56 of the sleeve 32 without a seal to prevent inadvertent un-mounting of the grommet cap 14 from the grommet 12.
The grommet cap 14 can also include a retaining device 57 for coupling the second end 22 of the extension cord 16 to the grommet cap 14. As illustrated in
The second end 22 of the extension cord 16 can be provided with a curved fastener 60, such as a hook or loop, for example, which can receive the rod 57 for coupling the extension cord 16 with the grommet cap 14. The upper surface 44 of the grommet cap 14 can also be provided with one or more grips, such as a handle, loop or tab, to facilitate grasping and un-mounting the grommet cap 14.
It is also within the scope of the invention for other retaining devices to be used to couple the grommet cap 14 with the extension cord 16. For example, the second end 22 can be coupled with an underside of the grommet cap 14 using an adhesive or weld. In another example, the grommet cap 14 can be provided with a clamp or spring clip for grasping the second end 22 of the extension cord 16. In yet another example, as illustrated in
Referring now to
To use the guest connection assembly 10, a user can grasp the grommet cap 14 by the rim 46 and un-mount the grommet cap 14 from the grommet 12 by pulling as described above with reference to
The guest connection assembly 10 mounted on the vertical surface 78 can be used in the same manner as that described above for the guest connection assembly 10 mounted on a horizontal surface. The user can un-mount the grommet cap 14 and pull the grommet cap 14 and extension cord 16 to a desired location, as illustrated in
The guest connection assembly 110 comprises a grommet 112 and a grommet cap 114 coupled with an extension cord 116 in a manner similar to that described above for the guest connection assembly 10. The grommet cap 114 can be moved between a mounted, stored position within the grommet 112 and an un-mounted, use position by pulling the grommet cap 114 away from the grommet 112 in the same manner as described above with respect to the guest connection assembly 10.
The extension cord 116 can have a second end 122 which includes a socket 124. In the embodiment illustrated in
The guest connection assembly 210 comprises a grommet 212 and a grommet cap 214 coupled with an extension cord 216 in a manner similar to that described above for the guest connection assembly 10. The grommet cap 214 can be moved between a mounted, stored position within the grommet 212 and an un-mounted, use position by pulling the grommet cap 214 away from the grommet 212 in the same manner as described above with respect to the guest connection assembly 10.
The extension cord 216 can have a second end 222 which includes a socket 224. In the embodiment illustrated in
While the guest connection assemblies 10, 110 and 210 have been illustrated as having an electrical socket, network plug socket and coaxial cable connector, respectively, the invention is not limited to only these types of connections. It is within the scope of the invention for the guest connection assembly to be configured to receive and transmit electrical power and/or data through any correspondingly suitable cord and to configure the socket to couple with any known coupling device provided for use with an electronic device. Non-limiting examples of sockets contemplated for use include an audio connector socket, a video connector socket, an audio visual socket and a high definition multimedia interface HDMI socket and the corresponding cords associated with each type of socket.
It is also within the scope of the invention for the second end 22, 122 and 222 to comprise one or more sockets 24, 124 and 224 and/or any combination of sockets. In addition, the cord 26, 126 and 226 can be provided at any desired length.
The guest connection assembly as described herein provides a compact, flexible, temporary connection which is relatively inexpensive to manufacture and easy to install and replace. The guest connection assembly is compact and takes up very little surface area in both the mounted and un-mounted position. The use of a grommet cap and grommet is simpler and less expensive to manufacture than systems which comprise complex slide and rotation mechanisms having multiple parts.
Because the extension cord is moveable relative to the grommet, the second end having the socket is flexible relative to the grommet and can be pulled in any desired direction away from the grommet to meet the needs of the user. The distance the user can pull the socket from the grommet is limited only by the length of the cord. This flexibility allows a single guest connection assembly to be utilized in a variety of locations, spaced from the grommet, to meet the needs of individual users.
Another advantage of the guest connection assembly is that when not in use, the extension cord is stored behind or underneath a surface, decreasing the chances that someone may step on or trip over the extension cord. In addition, when the guest connection assembly is in use, the grommet can be used for cord management of electronic devices and the extra cord length can be tucked into the grommet channel.
The seal on the guest connection assembly can be used to frictionally retain the grommet cap within the grommet such that the guest connection assembly can be mounted on both horizontal and vertical surfaces. In the case of a horizontal surface, the guest connection assembly can be mounted in a surface such that in the mounted position the extension cord extends down below the horizontal surface or alternatively, the guest connection assembly can be mounted such that the extension cord extends upwards from the horizontal surface. For example, the guest connection assembly can be mounted in a table such that the extension cord extends underneath the table in the mounted position or the guest connection assembly can be mounted within a lower surface of an overhead cabinet such that the extension cord extends upwards above the lower surface in the mounted position.
In addition, the seal can also provide a liquid tight seal between the grommet cap and the grommet to prevent liquid spilled on the surface in which the guest connection assembly is mounted from reaching the socket. In this manner, the socket can be protected from damage and, in the case of an electrical socket, can also help prevent electrical shock to a user.
To the extent not already described, the different features and structures of the various embodiments may be used in combination with each other as desired.
