Definitions

  • the invention relates to a light bulb support assembly, particularly for use with strings of lights which are are used on christmas trees and the like.
  • the light strings have been widely used to decorate christmas trees and the like because it brings a warming feeling to the family and passers by. During this season, it brings joy to children as well as adults.
  • Inclement weather such as snow and wind can cause light bulbs on the christmas trees situated outside to drop down from the bulb sockets after dangling in the wind. Hence the warm atmosphere is likely to be harmed. The replacement and repair of said light bulbs is difficult in such cold weather. Hence, some improvements to decrease this problem have been proposed.
  • Taiwan Utility Patent No.78210590 the inventor provided a novel connecting mechanism for a light bulb and bulb socket.
  • the inventor used a clipping plate having a hole thereon provided on the light bulb which locks to a button equipped on the outer wall of the bulb socket. No doubt the locking engagement of clipping plate and button suitably prevent the drop down of the light bulb from the bulb socket.
  • Taiwan Utility Patent Application 79205791 now abandoned, the inventor provided another kind of locking mechanism for a light bulb and bulb socket. Again it has the difficulty like the above-mentioned proposal of the inability to easily separate the two elements. Its structure also can not find a fulcrum for applying a tool.
  • a light bulb assembly comprises a tubular socket having connecting wires extending therein; and a connector which can be removably inserted in the socket and which supports the light bulb in use, the light bulb being connected to the connecting wires when the connector is inserted in the socket, and the connector having an outwardly extending flange which, when the connector is fully received in a socket, is spaced from the socket whereby the connector can be separated from the socket by use of the flange.
  • the flange on the connector could be maintained at a preselected distance from the socket by means of a force fit between the two components.
  • an internal flange could be provided in the socket against which the connector locates, the internal flange being positioned such that the flange on the connector is spaced from the socket.
  • the socket and connector have one each of a cooperating projection and open ended slot which engage when the connector is inserted in the socket so as to maintain the flange at a preselected distance from the socket.
  • the slot will be provided on the socket and the projection on the connector. More than one pair of cooperating projections and slots could be provided.
  • FIG. 1 to 4 comprises a cylindrical bulb socket 20 of known type within which are provided electrical connecting wires 51 (Figure 4).
  • a pair of slots 22 are provided in the upper surface 23 of the socket 20 arranged opposite one another.
  • the upper section of each slot 22 includes inwardly projecting portions 222.
  • a light bulb connector 30 is provided having a tubular body 32 into which can be mounted a light bulb 50.
  • the connector 30 includes electrical connecting wires (not shown) which enable the bulb 50 to be electrically connected to the wires 51 mounted in the socket 20.
  • the connector 30 has a pair of outwardly projecting, cylindrical bosses 31 positioned on opposite sides of the body 32 which, when the connector is inserted into the socket 20 ( Figures 2-4) locate in respective slots 22 in the connector 20. During insertion, the bosses 31 will slightly force apart the projections 222 which then close around the bosses 31 so as to retain them within the slots 22.
  • the top surface of the connector 30 is defined by an outwardly projecting flange 33 formed of two arcuate segments 33A and 33B. Spaces 331 are defined between the ends of the segments 33A, 33B.
  • the user can either grasp the flange 33 with one hand and the socket 20 with the other and draw them apart or insert a tool or his fingers into the groove 40 which acts as a fulcrum in order to force the two components apart.
  • said grasping plate or flange 33 has a larger diameter than the bulb 50, during the replacement, the fingers will not contact on said bulb 50. Since most of the force is located on said grasping plate 33, the bulb 50 will not be broken by excess force. Besides, even if said bulb 50 is broken grasping plate 33 will still make the replacement of said light bulb 50 safely and easily.
  • FIG. 5 illustrates an alternative form of socket 20′ in which slots 22′ are provided having inwardly extending projections 222′ which are positioned spaced from the upper surface 23′ of the socket 20′. Between the upper surface 23′ and the projections 222′ is defined a V-shaped entry slot 224.
  • Figure 6 illustrates a third example which is similar to the Figure 1 example except that the socket 20 ⁇ has an internal and external generally tapered form, the connector 30′ having a body 32′ which is also tapered so as to cooperate with the internally tapered bore of the connector 20 ⁇ .
