ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a decorative lamp, and particularly to a figurative structure for clamping a decorative lamp string.
2. Description of the Prior Art
In the conventional decorative lamp string for Christmas season, a plurality of sockets are mounted therein by using two or more than two power wires twisted together to connect such sockets in series; such a lamp string is subject to swinging or hanging in the air because of the sockets thereof not being fastened in place.
In the conventional decorative lamp string for a given festival, the figurative lamp-mounting frame is usually made of a metal, on which a plurality of socket assemblies connected in series with twisted power wires are mounted thereon. The power wires and the figurative lamp-mounting frame are usually not fastened together; as a result, the lamp string and the lamp-mounting frame are subject to separating from each other. Some of such lamp strings may be fastened in place with fastening cord; however, the sockets and the power wires are also subject to swinging and hanging in the air.
In the conventional decorative lamp string for Christmas season, please reference the U.S. Pat. No. 4,802,072, it is a direction fixture for decorative lamp series comprising a socket for a bulb, wires connected to said socket and a retaining ring attached to said socket, said retaining ring being provided with a notch extending longitudinally of the socket with the wires that are connected to said socket being positioned and retained in said socket so as to fixed said socket in a desired orientation and wherein said retaining ring has an outer face which is in registry with an end rim of said socket. In the aforesaid invention, the socket assemblies and the power wires are fastened in place with fastening slips, but the socket assemblies and the power wires appear to be out of order; therefore, the lamp string has to be fastened to a lamp-mounting frame with fastening cords.
In another conventional lamp string for Christmas season, please reference the U.S. Pat. No. 5,526,246, the front part of the figurative structure is provided with a fastening base, which is furnished with a plurality of hooks for clamping sockets respectively; then, the sockets are fastened to the figurative structure. When the bulbs wink, the figurative structure will be shown vividly. The back of the figurative structure is provided with a connection plate; as a result, such figurative structure can only be used for one-side decoration.
In still another conventional lamp string for Christmas season, such as U.S. Pat. No. 5,727,872, the bulb-plugging end of the socket assembly has two curved surfaces on both sides thereof, and one side thereof has two symmetrical arm plates extended out; the tail ends of such arm plates have two curved hooks respectively; the inner surface of the hooks each have a curved surface to fit to the figurative lamp-mounting frame. The outer ends of the two hooks form into an opening; each socket assembly has two arm plates to form into an opening so as to click to the metal rod of the figurative lamp-mounting frame, i.e., to have the socket assembly clamped to the metal rod of the figurative lamp-mounting frame.
SUMMARY OF THE INVENTION
The prime object of the present invention is to provide a figurative lamp-mounting frame, in which every lighting point is furnished with a fastening base, and each fastening base has an open end for plugging a decorative lamp; the open ends of every two adjacent fastening bases face opposite direction; the two adjacent fastening bases are connected together with single arms. Each of the fastening bases of the figurative lamp-mounting frame enables one of the socket assemblies to be clicked in place. The front and rear sides of each bulb mounted on the lamp-mounting frame are exposed to the air so as to have the winking of every bulb shown to form a vivid figurative structure.
Another object of the present invention is to provide a figurative lamp-mounting frame, in which every fastening base for clamping a socket assembly has two arm plates; one side of the two arm plates are furnished with two symmetrical hooks; a positioning plate is furnished above the hooks and on one side of the arm plates; the inner surface of the positioning plate is furnished with a concave surface to fit to a curved surface of the socket. Another positioning plate is furnished under the hooks and on one side of the arm plates, and the inner surface of the positioning plate is furnished with two symmetrical flat surfaces and a concave surface for positioning the lower part of the socket. When a socket assembly is plugging into the open end of the fastening base on the lamp-mounting frame, the upper and lower parts of the socket will be in close contact with the inner surface of the positioning plate for positioning so as to have the socket clamped in place by means of the symmetrical hooks.
Still another object of the present invention is to provide a figurative lamp-mounting frame, in which the open ends of two adjacent fastening bases face different directions for receiving sockets respectively; the bulb on each socket is not covered, i.e., the winking light of each bulb can be shown from the front and rear sides thereof; the mounting condition of each socket assembly can be seen clearly from the front and rear sides of the lamp-mounting frame.
A further object of the present invention is to provide a figurative lamp-mounting frame, in which connection arm plates are furnished between two adjacent fastening bases; the connection arm plates arranged in parallel extend through all the fastening bases.
A still further object of the present invention is to provide a figurative lamp-mounting frame, in which the connection arm plates between two adjacent arm plates have a suitable decorative side extended there-from.
Yet another object of the present invention is to provide a figurative lamp-mounting frame, in which the open end of every fastening base has two symmetrical hooks, which have a given flexibility for clicking a socket therein; also, the socket can be plugged in through the space formed with the two symmetrical flat surfaces so as to have the symmetrical flat surfaces of the lower part of the socket fastened in the positioning groove, and then the curved surfaces of the hooks will hold the curved surface of the upper part of the socket so as to have the socket assembly fastened in place without moving out.
