A socket for a light bulb having a socket housing to provide wired connection and an interior spring-clamp socket manufactured of a resilient material and having a notched separation extending longitudinally therethrough. The notch permits the deformation of the spring-clamp socket and expands when a light bulb is inserted and grasps it once therein. Removal of the bulb simply requires pulling the bulb straight out. Additionally the present invention is adaptable and replaceable for most existing lighting fixtures or applications.

Description:
BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates generally to electrical sockets and, more specifically, to a light bulb socket having an improved and expedient means of connection whereby the user may insert into place and establish electrical connection to a light bulb by simply inserting said light bulb into a spring-clamp socket with no rotational manipulation, furthermore the user may also remove a light bulb from the present invention by an opposed pulling action. 
   The present invention is a socket housing providing a base for electrical installation and wire contact and supplying power to a spring-clamp socket fabricated of a resilient material. The diameter of the spring-clamp socket is substantially similar to that of the threaded base of a conventional light bulb and includes a slot extending longitudinally through the side thereof. The slot gives the spring-clamp socket slightly deformable properties wherein insertion of the bulb base causes the socket to expand a bit to accept the bulb therein. This provides a frictional engagement that will maintain the light bulb in place without the need of threading or turning the bulb. The bulb will remain firmly therein until the user pulls it out.

   A compact lamp unit and associated socket for use in a projection system such as a slide projector, microfilm viewer, and so forth. The lamp unit includes a reflector molded from a plastic material and an electric lamp secured within the reflector. In order to decrease the axial dimension of the reflector and to avoid the use of pin connectors, electrical contacts for the lamp are pressed into recesses formed in the outer surface of the reflector. The reflector includes an opening at its apex through which electrical leads from the lamp extend outwardly of the reflector. The electrical leads are secured to the contacts by being forced into the recesses along with the contacts. This construction technique is fast and simple. The lamp unit also includes a handle to enable a heated lamp unit to be replaced by the user and a guide means to enable the lamp unit to be oriented quickly and accurately upon insertion into the socket. In their preferred forms, the handle and the guide means are identically configured and comprise fins extending outwardly of the convex surface of the reflector, the fins lying on opposite sides of the opening and in the same plane. The socket into which guide means is inserted includes a first upstanding member defining a reference plane against which a portion of the reflector is engaged in use. A second upstanding structure engages another portion of the reflector to securely retain the reflector when it is inserted into the socket. The socket includes a pair of flexible contacts engageable with the contacts carried by the lamp unit, the socket contacts being positioned in a plane substantially parallel with the reference plane. When the lamp unit is inserted into the socket, the socket contacts are flexed sufficiently to make good electrical contact with the contacts carried by the lamp unit. A retention mechanism in the form of a flexible bail may be used to prevent inadvertent displacement of the lamp unit from the socket. United States Patent

The terminals on the base of the light bulb are connected to conductor members extending from the terminals on the base of the light bulb to the terminal screws on the base of the holder with the conductor members being soldered to the terminals on the base of the light bulb thereby eliminating the necessity of the light bulb being inserted into and twisted in relation to a light bulb socket in order to mount the light bulb in the socket. In one embodiment of the invention, the holder includes a locking retainer for engagement with one of the bayonet pins which conventionally project radially from the base of the light bulb to mechanically lock the bulb in position. In another embodiment, the holder which snugly engages the base of the light bulb is provided with a slot enabling passage of one of the radially extending pins on the base of the light bulb. The positive soldered connection between the light bulb terminals and the conductor members eliminates points of corrosion which frequently result in the electrical energy supplied to the light bulb becoming interrupted. 
   While there are other light bulb sockets that may be suitable for the purposes for which they were designed, they would not be as suitable for the purposes of the present invention, as hereinafter described. 
   SUMMARY OF THE PRESENT INVENTION 
   A primary object of the present invention is to provide a light bulb socket that facilitates the easy and quick installation and removal of a light bulb. 
   Another object of the present invention is to provide a light bulb socket having a socket housing for connection to an electrical source and a spring-clamp socket residing therein. 
   Yet another object of the present invention is to provide a light bulb socket that has a notched spring-clamp socket that flexes for the insertion or removal of a light bulb 
   Still yet another object of the present invention is to provide light bulb socket that has a spring-clamp socket that is fabricated of a resilient material. 
   Yet another object of the present invention is to provide light bulb socket that is available in sizes to accommodate existing light bulb sockets. 
   Additional objects of the present invention will appear as the description proceeds. 
   The present invention overcomes the shortcomings of the prior art by providing a socket for a light bulb having a socket housing to provide wired connection and an interior spring-clamp socket manufactured of a resilient material and having a notched separation extending longitudinally therethrough. The notch permits the deformation of the spring-clamp socket and expands when a light bulb is inserted and grasps it once therein. Removal of the bulb simply requires pulling the bulb straight out. Additionally the present invention is adaptable and replaceable for most existing lighting fixtures or applications. 
   The foregoing and other objects and advantages will appear from the description to follow. In the description reference is made to the accompanying drawing, which forms a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
   The following discussion describes in detail one embodiment of the invention (and several variations of that embodiment). This discussion should not be construed, however, as limiting the invention to those particular embodiments, practitioners skilled in the art will recognize numerous other embodiments as well. For definition of the complete scope of the invention, the reader is directed to appended claims. 
     FIG. 1  is an illustrative view of the present invention in use  10 . The present invention  10  is a light bulb socket  12  having a substantially smoothbore bulb-receiver socket  12  with a longitudinally disposed notch  18  that enables the socket  12  to expand to grip the bulb therein thereby forming a spring clamp socket  12 . The socket  12  is retained within a housing  13 . The socket  12  frictionally engages the light bulb base  16  as the bulb  14  is pressed into socket interior  20  until seated. To remove the light bulb  14 , the light bulb  14  is pulled from the socket  12  without the need for twisting, turning, aligning or the use of tools. The present invention  10  provides a light bulb socket  12  where a user simply pushes a light bulb  14  into the resilient tension socket  12  and to replace the bulb  14 , the light bulb  14  is pulled out of the socket  12  and another bulb  14  is pressed into service. 
     FIG. 2  is a perspective view of the steps involved in installing and removing a light bulb  14  from the present invention  10 . Shown are the steps taken for the installation and removal of a light bulb  14  from the socket  12  being first the placement of slipping the threaded base  16  of the bulb  14  into the socket interior  20  where it is retained in electrical communication within the socket  12 , then to remove the bulb  14  the user simply pulls the bulb  14  till deformation of the socket  14  by separating the notch  18  is increased to a point where the bulb  14  may be dislodged. 
     FIG. 3  is an exploded perspective view of the present invention  10 . Shown is the present invention  10 , an electric socket  12  for a standard light bulb having a spring-clamp socket  12  within a socket housing  13  with a center contact  22  and two wire contacts  22  held in place by screws  24 . The spring clamp action of the socket  12  is provided by the notch disposed therein. 
     FIG. 4  is a rear perspective view of the present invention  10 . Shown is a rear perspective view of the socket of the present invention  10  having a spring-clamp socket  12  within a socket housing  13 . Also shown are the electrical contacts  22  held in place by screws  24 . Centrally disposed in the bottom is a threaded mounting recess  30  for securing the socket to a lighting fixture. The light bulb is frictionally held therein until selectively released simply by pulling it out.
