Description:
FIELD OF THE INVENTION 
   The present invention relates to a sealing member for window and door openings in buildings, through which an electrical cord passes from a portable electrical generator located on the outside of the building, which provides weather proofing and prevents the entry of carbon monoxide into the building through the openings. 
   BACKGROUND OF THE INVENTION 
   There are large numbers of portable electric generators which are used by private individuals, home owners and businesses as temporary emergency sources of electrical power during electrical power outages in different geographical regions of the world. These power outages have many causes such as snow, hail and ice storms, tornadoes, sandstorms, tropical storms, hurricanes, flooding, etc. In addition power outages occur during excessively prolonged periods of hot or cold weather as a result of failure of a regional or national power grid. Power outages caused by severe weather can last for days and sometimes weeks. During this time weather proofing the opening through which the electrical cord passes is a problem. This opening is usually a window, door or garage door. Most homes and businesses do not have any existing permanently installed outdoor electrical boxes or generator sub panels. Nor do they have any permanently installed transfer switches or other electrical power inlet boxes for the purpose of temporary connection to a portable external generator as a source of electrical power. Therefore the lack of permanently installed outdoor electrical connection capabilities for conveying electrical power into a building are usually associated with electrical power cords being run from an electrical generator through an opening in the building to the interior of the building to wherever the electrical power is required. The usual openings are windows, doors and/or garage doors. Running the electrical power cords through these openings leaves a gap in the openings which permits the entry of generator fuel and exhaust fumes, toxic carbon monoxide, rain, snow ice, sand and other additional adverse weather conditions. In addition, insects and/or small animals, such as rodents, can enter the building. These insects and animals can carry human diseases such as malaria, encephalitis, etc. The problem of them entering the building increases during wet conditions such as after tropical storms or hurricanes. Further, driving rain can enter the building through the opening and cause damage to the occupants or contents of the building. 
   DESCRIPTION OF THE PRIOR ART 
   U.S. Pat. No. 5,803,764, discloses a method and apparatus for weather proofing an opening through which an electrical cord passes. A truncated conical sealing element is formed from rubber or plastic and surrounds an end portion of the electrical cord in a manner that precludes the passage of water thereby. A truncated conical opening is provided in an element into which the electrical cord passes. The truncated conical sealing element cooperates with and engages the truncated conical opening in an interference fit to weather proof the conical opening and preclude the entry of water and insects. As a result, the truncated sealing element must be positioned within the truncated conical opening to provide a weather proof seal for the electrical cord entering a building. Since the truncated conical sealing element is normally sealed to the electrical cord, it cannot be easily repositioned on the cord. Therefore the portion of the electrical cord at which it enters the building cannot be easily changed. 
   U.S. Pat. No. 6,564,512, discloses a temporary panel which can be mounted in a window to allow air to be exhausted from a building while preventing reentry of evacuated dust and fumes. The panel has a large aperture therein for connection to an air moving system. This aperture is substantially larger than the diameter of an electrical cord and there is no provision to seal the aperture around the electrical cord to prevent the entry of water and insects. 
   U.S. Pat. No. 1,125,015, discloses a window ventilator. The ventilator includes a substantially rectangular bar having sufficient length to extend across a window sill and having its diagonally opposed edges cut away to form recesses. The upper edge of the ventilator is adapted to receive the lower edge of a window while the lower edge is hingedly connected to the window sill. The ventilator includes openings formed transversely and diagonally therethrough to allow air to flow through the apertures. However, if an electrical cord were passed through the apertures there are no provisions to seal the aperture around the cord to prevent the entry of water and insects. 
   SUMMARY OF THE INVENTION 
   Portable electrical generators are used to temporarily supply electrical power to homes and business in times of emergency and severe weather. The portable generators are normally located outside of the home or business for safety reasons. An electrical cord or wire must then be run from the generator to the inside of the home or business to supply electricity to the appliances in the building. The most convenient point of entry into a building is through an open window or door. The present invention provides a device which permits the passage of an electrical cord or wire through an open window or door while providing a weather proof seal for the opening and prevents the entry of carbon monoxide, adverse weather conditions, insects and small animals into the building. The device also prevents damage to the electrical cord or wire by not permitting the window or door to close directly onto the cord. A provision is made in the device to allow the passage of the electrical cord therethrough while maintaining the integrity of the sealed opening. The length of the electrical cord may be adjusted while it is protected by the device. The device may be formed from a number of different materials, closed cell foam being a preferred material. The device is preferably an elongate member with a provision for one or more electrical cords to pass transversely therethrough. The opening for the electrical cord can be adjusted to accommodate different size cords of varying diameters. 
   Accordingly, it is an objective of the instant invention to provide a device which permits the passage of electrical cords through an open window or door and also provide weather proofing for the opening. 
   It is a further objective of the instant invention to provide a device which permits the passage of electrical cords through an opening in a building while preventing the entry of carbon monoxide and other fumes into the building. 
   It is another further objective of the invention to provide a device which permits the passage of electrical cords through an opening in a building while preventing the entry of insects and small animals. 
   It is a still a further objective of the instant invention to provide an adjustable transverse opening through the device for the passage of electrical cords therethrough of varying diameters, sizes and shapes. 
   It is yet another objective of the instant invention to allow the device to be readily sized to accommodate different size window and/or door openings. 
   It is a still yet a further objective of the invention to provide protection of the electrical cords from damage caused by closing the window or door.

   DETAILED DESCRIPTION OF THE INVENTION 
   Referring now in detail to the drawings wherein like parts have like reference numerals, a new and improved window seal and electrical conduit retainer embodying the principles and concepts of the present invention and generally described by reference numeral  10  will be described.  FIG. 1  is a perspective view of the window seal of the present invention. A seal  12 , preferably made from resilient closed cell foam, is constructed and arranged to be placed in an opening in a window and prevent the entry of moisture, insects and hot or cold air into the building. Other materials from which the seal  12  may be formed include plastics, organic materials, foams, and resins. When organic materials are used they should be protected from moisture by encasing them with moisture resistant materials or coating them with moisture resistant materials. The seal could be formed as one continuous piece of material or a plurality of pieces of material encased within an envelope or enclosure. The seal could be manufactured in certain standard sized and then cut by the user to fit specific window or door openings. 
   The elongate seal  12  is provided with a passage or raceway  14  which allows an electrical cord or conduit  15  to pass through the seal from a front face  16  to a rear face  18 . An electrical cord  15  is usually provided with a male electrical connector on one end and a female electrical connector on the other end. In certain applications a male electrical connector  20  is provided on both ends as illustrated in  FIG. 1 . This particular electrical cord is normally employed to connect a portable electrical generator (not shown) to special electrical panel (not shown) in a home or business. The special electrical panel in turn is connected to the main electrical panel which supplies electrical power from the power company to the electrical appliances in the home or business. The special electrical panel disconnects the electrical power from the power company and substitutes the electrical power from the electrical generator. The passageway or raceway  14  is preferably sized to accommodate a particular electrical cord and prevent the entry of moisture and/or insects into the building. In an alternative and more conventional setting the electrical cord has a male connector on one end and a female connector on the other end. This is usually the setting found in buildings under construction prior to the installation of electrical power by an electrical utility. 
   Male and female electrical connectors are substantially larger in diameter than the electrical cord to which they are attached and as a result it would be impossible to thread an electrical connector through the passage or raceway  14  from one side of the seal to the other side. Therefore a slit  22 ,  FIG. 2 , is provided in the seal between the passageway  14  and an exterior surface thereof. In the embodiments illustrated in  FIGS. 2 and 3  the silt  22  extends between the passageway  14  and the bottom surface  24  of the seal. When the resilient and flexible seal  12  is bent, as illustrated in  FIG. 3 , the silt  22  separates and allows an electrical cord  15  to be inserted into passageway  14 . After the electrical cord has been inserted, the seal is then returned to its original position. Both sides  23  of the slit  22  are returned together in an abutting relationship thereby confining the electrical cord in the passageway and effectively sealing the passageway  14  to prevent the entry of moisture and/or insects into the building. In the embodiments of the invention illustrated in  FIGS. 2 ,  3 ,  5  and  9  the passageway is located approximately in the middle of the depth of the seal  12 . The slit  22  extends from the passageway  14  to the bottom surface  24  of the seal. In the embodiment illustrated in  FIG. 4 , the passageway is located adjacent the bottom surface of the seal and the slit  22  is just a line which extends along the junction of the passageway and the bottom surface of the seal. 
   The seal illustrated in  FIG. 5  is provided with a passageway  14  which is noncircular in cross section. This shape is designed to accommodate electrical cords which are substantially flat or noncircular in cross section. 
     FIGS. 6 and 7  are directed to another embodiment of the invention. The passageway  14  has an aperture  26  open to the exterior of the seal for insertion of an electrical cord into the passageway. After the electrical cord has been inserted into the passageway a flap  28  is positioned over the aperture  26  thereby closing the passageway and securing the electrical cord therein. The flap  28  may be a separate member hingedly secured to the bottom  24  of the seal, as illustrated in  FIG. 7 . The flap  28  may be held in position closing aperture  26  by frictional engagement of the seal material forming aperture  30 , by securing means not shown, by the weight of the window or door bearing down on the seal, or by forming the flap  28  of a “plastic memory” material. This is defined as a material which will return to its original shape after it is deformed. Alternatively, the flap  28  may be formed from a portion of the seal  12 , as illustrated in  FIG. 6 . When it is desired to insert the electrical cord into the seal the flap  28  is removed from a recessed aperture  30 , a portion of the flap is hingedly connected to the seal  12 . The electrical cord is inserted into the passageway and the flap  28  is returned to the recessed aperture. The flap is normally held in the recessed aperture by friction. However, additional securing means could be employed to retain the flap in the recessed aperture. In an alternative embodiment, the flap  28  is completely removed from the recessed aperture and returned thereto after the electrical cord has been inserted into the passageway. 
     FIG. 8  is directed to an additional embodiment of the invention. A portion of the seal  12  adjacent the passageway is formed as a flexible, adjustable sealing member  32  for the passageway  14 . The sealing member  32  comprises a portion of the bottom  24  of the seal and a portion of the periphery of the passageway  14 . The sealing member  32  is formed so as to have a tendency to curl towards the interior of the passageway  14 . This allows different size electrical cords  15  to be placed into the passageway and then have the sealing member  32  close the passageway to the exterior, thereby maintaining a moisture and insect resistant seal. 
     FIG. 9  illustrates an embodiment wherein two passageways are provided for the passage of two electrical cords from the exterior of a building to the interior thereof. Any number of passageways could be provided in the seal. It is common for portable electrical generators which have an output above a certain level to have multiple electrical outputs thereby requiring multiple electrical cords passing into a building. Lager electrical generators also provide both 220 volt and 110 volt outputs. 
     FIG. 10  illustrates the seal of the instant invention positioned in a conventional double hung window  34  located in a wall  36  of a building. The seal has two grooves  38  and  40  extending lengthwise along a top and bottom portion thereof. These grooves allow the seal  12  to engage the window sill  42  and lower window  44  and establish a sealing relationship between these members so as to prevent the entry of moisture and/or insects into the building. An additional seal  45  is located between the upper and lower windows to prevent the entry of moisture and/or insects into the building. The combination of seals  12  and  45  provide a sealing relationship which also prevents the hot or cold air on the exterior of the building from entering into the building. 
     FIG. 11  illustrates an embodiment of the seal wherein a flange  44  extends downwardly, lengthwise along a bottom edge portion of the seal. This flange is designed to engage a specific window or door opening and provide a seal for the opening. A layer of material  47 , such as vinyl for example, encases the seal and acts as a protective barrier for the seal material against the elements of the weather. 
     FIG. 12  illustrates an embodiment wherein a single groove  38  is provided which extends lengthwise along a top or bottom portion of seal  12 .  FIG. 12  also illustrates an embodiment wherein the seal  12  is formed as an expandable, hollow bladder  52 . The interior of the bladder  52  is filled with a gel or a fluid. The fluid can be a gas, such as air, or a liquid, such as water. A gauge and pressure regulator  56  is connected to the interior of the bladder  52 . The gauge allows the pressure of the fluid inside of the bladder to be monitored and the pressure regulator allows removal of and introduction of fluid into the bladder to maintain a desired pressure. 
     FIG. 13  illustrates an embodiment wherein a groove  38  is provided on one side of the seal  12  and a flange  44  is provided on an opposite side of the seal.  FIG. 14  illustrates an embodiment wherein two V-shaped grooves  46  are provided which extend lengthwise along a top and bottom portion of the seal  12 . 
     FIG. 15  illustrates the seal of the present invention installed in a gliding window  48  which includes a frame  50 . Gliding windows  48  move horizontally between open and closed positions and the frame  50  holds the window in the wall  36  of the building. The seal  12  is installed vertically along a side of the gilding window between a window portion and the frame  50 . A passageway  14  is provided in the seal  12  for the passage of an electrical cord through the seal from the exterior to the interior of the building. An additional seal (not shown), similar to seal  45  if  FIG. 10  is installed between windows  48  to prevent entry of moisture, weather, fumes, insects, etc. into the building. 
     FIG. 16  illustrates an embodiment of the seal of the instant invention wherein reinforcement members  60  are installed in the seal and extend parallel to the raceways  14 . These reinforcement members preferably extend along both sides of each raceway  14  from the front face  16  to the rear face  18  of the seal and prevent the seal and raceway from being crushed by an extreme force being applied to the seal. An example of this force would be a heavy garage door lowered onto the seal and electrical cords. In another embodiment, not illustrated, the reinforcement members  60  would extent longitudinally of the seal, substantially parallel to the front and rear faces of the seal, substantially the entire length of the seal. There would be a sufficient number of reinforcement members  60  to prevent the raceways  14  from being crushed. The reinforcement members  60  are preferably made from metal, but could also be made from any material which is stiff and incompressible and would prevent an exterior force from crushing the seal  12 . 
     FIG. 17  illustrates a plug  62  which could be placed around an electrical cord and inserted into an end of the passageway or raceway  14  in the event that the electrical cord is smaller in diameter than the passageway. Each end of the passageway  14  would have a plug  62  surrounding the electrical cord. The plug is provided with a slit  64  so that is can be opened and placed around the electrical cord in a manner similar to the seal  12 . The interior portion  66  of the plug  62  can be different shapes. For example, the interior  66  could be substantially flat so as to accommodate a flat electrical extension cord and the exterior portion  68  could be circular in cross section to conform to the shape of the passageway  14  in the seal. Utilizing these plugs different size and shaped electrical cords could be used with a substantially standard size seal  12 . Also, if there is a size difference between the electrical cord and the passageway  14  the ends of the passageways could be plugged with cut up pieces of foam or seal material.
