Description
Z2~0 ELECTRI CAL PLUG AND OUTLET P ROTE CTOR
This invention relates to a device for removing without damage an electrical plug from an electrical outlet by application of force on t~e connecting electrical cord when such force is applied fram a direction not normal to the outlet face. More specifically, it relates to such a device that is easily transferable between appliances, that is inexpensive, and that is easily manufactured.
Operators of portable electrical appliances, such as vacuum cleaners and rug shampooers, or portable electrical tools, often must move the electrical plugs on their equipment from one electrical outlet to another. Usually, this action is only taken after the electrical equipment is as distant from the powering electrical outlet as the length of the electrical power cord will allow. Commonly, in such circumstances, the electrical equipment is not generally perpendicular to the plane extending through the face of the outlet; indeed, it may be nearly parallel to such plane.
Tenæion applied to the power cord at a point distant from and not generally perpendicular to the plane of the outlet face will result in a lateral force being experienced by its connected plug at the outlet. Since electrical plugs are designed to separate at a perpendicular or generally perpendicular angle from outlets, such lateral force on the plug may result in damage to the outlet, the plug, and the cord connected to the plug.
Means have been suggested for transforming power cord tension, acting non-perpendicularly to the plane of an outlet face, into a force on a connected plug acting generally -- perpendicular to the outlet fa oe. Such means involve an arm or arms extending laterally from a specially-configured plug, or from an attachment secured to the plug, which arm ~lZZZ90 or arms contact the outlet sur~ace or a wall surface surroundlng the outlet. Upon a lateral force being applied to the axially-outward end of the plug or its attachment ~y tension on the power cord, the most lateral extension of the arm or arms on that side of the plug to which such force is applied acts as a point of pivot for the force. The greater the distance of the point of pivot from the plug prongs, the more axial is the force disengaging the plug from the outlet. The plug or the attachment to which it is secured should have a length sufficient to transform the lateral force acting thereon into an axial force sufficient to disengage the plug from the outlet.
Devices as described above which allow disengagement without damage of plugs from outlets by application of tangential force to the outward end of the plug or an attachment to the plug, are well-known. However, such devices described in the prior art have been either specially-configured plugs, permanently attached to power cords, or permanent attachments for such plugs.
Besides allowing for disengagement between an electrical plug and outlet without damage when a force, not generally perpendicular to the outlet face, is applied to a connected power cord, the device of the subject invention is quickly and easily connected to and disconnected from the plug and power cord, is adaptable to various shape plugs, is inexpensive to manufacture, and is durable. The device of the subject invention also gives support to plugs with deformed prongs so that they can maintain better mechanical and electrical connection. The device of this invention is comprised of a thin, non-conducting plate member, a lever member, and a flexible retaining means. The plate member l~ZZZ90 is adapted to be mounted between a plug and an outlet and has apertures therein so that the prongs of the plug can extend therethrough into the outlet. The distance between the apertures and the perimeter of the plate member at all points along the perimeter of the plate member are sufficiently great that pivotal motion of the plate member about any point on its perimeter results in separation of the plug from the outlet by causing the plate to move outwardly from the face of the outlet in a direction generally perpendicular to the outlet face. The lever member is rigid and has one end rigidly attached to the plate member, and extends outward from the plate member. The plate member and lever member are adapted to rotate together as a unitary body about a point on the perimeter of the plate member. A retention means is mounted to the other end of the lever member for flexibly retaining thereon a power cord connected to the plug, the flexible retention means having adjacent resilient members adapted to flex to permit facile, ready retention of the cord and connected plug on the device while also permitting facile, ready detachment therefrom. The lever member is sufficiently long that a tension force applied to the power cord in a direction generally transverse to that in which the lever member extends acts to pivot the plate member about a point on its perimeter to pull the prongs of the plug out of the outlet. In another form of the invention, the plate member is circular and the apertures are centred therein. In yet another form of the invention, the flexible retaining means is a flexible, resilient second plate member having intersecting cuts therein defining resilient segments which yieldably deflect to allow the plug to be passed therethrough in directions toward or away from said plate member.
In still another form of the invention, the inner tips of the segments of the second plate member are removed to allow a power cord extending through the second plate member to slidably move therethrough. In still yet another form of the invention, the lever member is a shroud connecting the perimeter of the plate .....
1~2Z~90 member to the perimeter of the second plate member, the shroud having an aperture therein sufficient to allow the plug to be grasped and inserted through the plate member apertures. In another form of the invention, the device of the invention is formed from a non-conducting plastic. In a final form of the invention, the perimeter of the plate member is limited in size such that, when the device is in use, the plate member does not extend to cover any electrical openings in the outlet, except those openings corresponding to the apertures in the plate member.
Unlike prior art devices, an electrical plug and connected power cord may very quickly and easily be connected to or disconnected from the device of the subject invention.
Suitability of the device ~o mass production techniques results in a low cost. Simple but effective design results in the device being durable.
The instant specification sets forth the best mode known to the inventor of carrying out the invention, but it is pointed out that the specific instruction and method shown herein are for illustxative purposes and for purposes of example only. Various minor changes and modifications may obviously be needed without departing from the spirit and scope of this invention.
The invention will now be more fully described by reference to the zccompanying drawings which are made a part of the specification. In the drawings:
Figure 1 is a side view of the plug protector device.
Figure 2 is a top view of the plug protector device.
Figure 3 is a back view of the plug protector device.
Figure 4 is a front view of the plug protector device.
Figure 5 is a perspective view of the plug protector device.
Referring now to the preferred form of the plug protector device, as set forth in the drawings, a hollow frustroconical 7;~ an in~rn~l ~ize sufficient to housean electrical 112Z~90 plug 12, is injection molded from a non-conducting, flexible, resilient, plastic. T~e ~ody 11 has a side opening 13 with dimensions- sufficient to allow hand manipulation of a plug 12 within the body. The body further has a larger end 14 in the approximate center of which is a circular opening with diameter slightly larger than that found on a household appliance electrical power cord 16. In the smaller end 17 are centrally located two rectangular openings 18 and a circular opening 19 with relative spacing therebetween corresponding to that between the two powered prongs and the safety prong of a standard electrical plug. Openings 18 and 19 are located relative to smaller end 17 such that with plug prongs 21 inserted therethrough, plug 12 is centrally located against smaller end 17. The smaller end 17 is sufficiently thin that its interposition between a plug and an outlet will not affect either their mechanical or electrical connection. The diameter of the smaller end 17 of the body is as large as is possible within the constraint of maintaining access to the neighbouring set of openings in the outlet. Within that constraint, the diameter has sufficient size than when the body is pivoted at a position on the smaller end perimeter 20, the prongs 21 extending from plug i2 through openings 18 and 19 of the smaller end 17 will disengage the openings in the under-lying electrical outlet by motion generally perpendicular to the face of the outlet. The length of body 11 is such that a tensile force on connected power cord 16 is sufficient to result in such disengagement. Body 11 has approximately four cuts 22 extending radially from the larger end opening _ 15 to the vicinity of the larger end perimeter 23. The larger end 14 ~and the remainder of body 11 of the device) is formed from material of sufficient flexibility and resiliency llZ2290 that th~ quarters of larger end 14 ~if four cuts are used~ j will separate sufficiently to allow an electrical plug 12 to pass therethrough but will return to a near planar configuration after such passage. Larger end opening 15 is of sufficient diameter to allow slippage of power cord 16 therethrough.
In operation, an electrical plug 12 having an attached power cord 16 is pushed through larger end 14 of body 11.
After such entry, power cord 16 is slidably constrained within larger end opening 15. The prongs 21 of plug 12 are then directed through the corresponding openings 18 and 19 in the smaller end 17 by manipulation through side opening 13. With the prongs 21 of plug 12 extending through openings 18 and 19 in smaller end 17 and being maintained in such position by a manual force applied through side opening 13, and with power cord 16 extending through larger end opening 15, body 11 is brought adjacent to an electrical outlet and the prong 21 rotated as required for insertion in the outlet. An operator can then commence to utilize the electrical equ~pment to which the power cord 16 is connected. If the electrical equipment is being operated at a position not generally perpendicular to the outlet face when power cord 16 becomes fully extended, power cord 16 will act at a position on the circumference of larger end opening 15 to create a lateral force on body 11. Body 11 will then pivot at the angularly-corresponding position on smaller end perimeter 20. Such pivotal movement creates a generally outward displacement of prongs 21 from the outlet openings, thus avoiding damage to both the prongs and the outlet. After disengagement of the plug and ~ody from t~e outlet, prongs 21 of plug 12 are pulled back through openings 18 and 1~ and plug 12 is pulled back throug~ t~e larger end 14. If desired -plug 12 may remain llZZ290 ~ithin th~ body 11 to f acilitate the rapid re-use of the tr ~
