SAFETY MECHANISM ADAPTED FOR A LIGHT BULB SOCKET SO AS TO SECURELY RECEIVE THEREIN AN ENERGY SAVING BULB
First Claim
1. A safety mechanism in a light bulb socket having a socket plate and a pair of holes diagonally defined in the socket plate, each hole being composed of an insertion hole and a positioning hole, the safety mechanism comprising:
- at least one sliding block adapted to be movably received in the socket plate and having a body, a wedged head formed on a distal end of the body to be adapted to be extending into a joint between the insertion hole and the positioning hole, an abutting block formed on a side of the body and composed of an inclined first abutting face, a positioning recess and a first plane formed between the first abutting face and the positioning recess; and
a releasing block adapted to be movably mounted in the socket plate and having an elongated body and provided with, on at least one side face thereof, an inclined second abutting face corresponding to and engaged with the first abutting face of the at least one sliding block, a boss adjacent to a distal end of the inclined second abutting face to correspond to and be received in the positioning recess and a second plane to correspond to the first plane such that when an insertion head is inserted into the insertion hole, the insertion head is easily extend over the wedged head of the sliding block to be securely received in the positioning hole and when the insertion head is to be away from the hole, movement of the releasing block toward the at least one sliding block allows the boss to be received in the positioning recess and forces the at least one sliding block to move away from the hole to free the insertion head from the wedged head and movement of the insertion head releases limitation to the boss from the positioning recess as a result of engagement between the insertion head and the wedged head.

Abstract
A safety mechanism includes a pair of sliding blocks each movably received inside the light bulb socket and a releasing block operably connected to each of the pair of sliding blocks to activate movement of the sliding blocks for releasing an energy saving light bulb. Each of the sliding blocks is provided with a first spring received in a first receiving compartment, an inclined first abutting face and a positioning recess so that when the insertion head of the energy saving light bulb passes over the wedged head of the sliding block, the sliding block is moved to allow the insertion head of the energy saving light bulb to be moved from the insertion hole to the positioning hole.

-
at least one sliding block adapted to be movably received in the socket plate and having a body, a wedged head formed on a distal end of the body to be adapted to be extending into a joint between the insertion hole and the positioning hole, an abutting block formed on a side of the body and composed of an inclined first abutting face, a positioning recess and a first plane formed between the first abutting face and the positioning recess; and a releasing block adapted to be movably mounted in the socket plate and having an elongated body and provided with, on at least one side face thereof, an inclined second abutting face corresponding to and engaged with the first abutting face of the at least one sliding block, a boss adjacent to a distal end of the inclined second abutting face to correspond to and be received in the positioning recess and a second plane to correspond to the first plane such that when an insertion head is inserted into the insertion hole, the insertion head is easily extend over the wedged head of the sliding block to be securely received in the positioning hole and when the insertion head is to be away from the hole, movement of the releasing block toward the at least one sliding block allows the boss to be received in the positioning recess and forces the at least one sliding block to move away from the hole to free the insertion head from the wedged head and movement of the insertion head releases limitation to the boss from the positioning recess as a result of engagement between the insertion head and the wedged head. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9)

10. In a light bulb socket having a socket plate and a pair of holes diagonally defined in the socket plate for receiving therein a pair of insertion heads of a light bulb, wherein the improvements comprise:
-
at least one sliding block adapted to be movably received in the socket plate and having a body, a wedged head formed on a distal end of the body to be adapted to be extending into a joint between the insertion hole and the positioning hole, an abutting block formed on a side of the body and composed of an inclined first abutting face, a positioning recess and a first plane formed between the first abutting face and the positioning recess; and a releasing block adapted to be movably mounted in the socket plate and having an elongated body and provided with, on at least one side face thereof, an inclined second abutting face corresponding to and engaged with the first abutting face of the at least one sliding block, a boss adjacent to a distal end of the inclined second abutting face to correspond to and be received in the positioning recess and a second plane to correspond to the first plane such that when an insertion head is inserted into the insertion hole, the insertion head is easily extend over the wedged head of the sliding block to be securely received in the positioning hole and when the insertion head is to be away from the hole, movement of the releasing block toward the at least one sliding block allows the boss to be received in the positioning recess and forces the at least one sliding block to move away from the hole to free the insertion head from the wedged head and movement of the insertion head releases limitation to the boss from the positioning recess as a result of engagement between the insertion head and the wedged head. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
