Bulb gripper for holding decorative lights

Abstract

A bulb gripper for decorative light holder has a U-shaped body with projections on the interior surface that enable the bulb gripper to securely hold many different sizes of decorative light bulbs. The interior surface of each arm of the body has an inward tooth near the opening followed by several three spaced apart projections. The projections may have a tab portion which is connected to the arm by a narrower connector. The projections and the teeth on the arms form a ledge which supports the decorative light. A smaller U-shaped projection or several projections which are sized and configured to hold a mini-light are provided at the base of the U-shaped body. The arms can flex outward so that the body can receive and securely hold the decorative light.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

(13) We provide a bulb gripper for a decorative light holder which has a U-shaped body with projections on the interior surface that enable the bulb gripper to securely hold a mini-light, or a C7 light or a C9 light as well as the newer C4, C5, C6, C12 and G28 sizes. This bulb gripper can be on a stake or attached to a housing that enables the bulb gripper to be attached to a gutter, siding, shingles or other structures.

(14) A first present preferred embodiment of our bulb gripper is shown in FIG. 1. The bulb gripper 10 has two arms 31, 32 attached to a base 33 that together form a U-shaped body 30. The U-shaped body is attached to a stake or housing which is used to place the decorative light at a desired location. The interior surface of each arm of the body has an inward tooth 34 near the opening followed by three spaced apart projections 35, 36, 37. A smaller U-shaped projection 38 is at the base of the body. This smaller U-shaped projection 38 is sized to hold a mini-light. Because a mini-light has a bulb which is straight, the U-shaped projection is intended to grip mini lights by the socket and C3, C4, C5, and some smaller diameter C6 lights at the neck. The flats 39 at the ends of the U-shaped projection, along with tooth 34 and three projections 35, 36, 37 on each arm 31, 32 define a circular opening that is sized to receive and securely hold the socket of a C7 light. The arms can flex outward so that the body can receive and securely hold the socket containing a C9, C12 or new G-sized decorative light.

(15) In recent years LED lights have become available that differ somewhat in size from their incandescent counterparts and are sold in new sizes called C4, C5 and C6. Furthermore, the socket can also vary in size depending upon the manufacturer. The bulb gripper disclosed here can be used to securely hold traditional decorative lights as well as the newer sizes of LED decorative lights. As can be seen in FIGS. 8 and 9, the bulb gripper 10 engages the decorative light 40 just above the top of the socket 41 and the neck of the bulb 42, except for mini-lights which do not have a narrower neck. The projections 35, 36, 37 on each arm 31, 32 that project inward from the U-shaped body of the bulb gripper are thin and form a ledge which supports the decorative light and prevents the light from moving up or down. The ledge helps the arms securely hold the light bulb in an upright vertical position shown in FIG. 7 and assures that all of the lights bulbs in a set are held the same position. The projections 35, 36, 37 that form the ledge may be mid-way between the top surfaces and the bottom surfaces of the arms or close to either the top surfaces or the bottom surfaces of the arms. Alternatively, the ledge may be formed by a single projection on each arm rather than multiple projections on each arm as shown in the drawings.

(16) A second present preferred embodiment 4 of the bulb gripper is shown in FIG. 2. This embodiment is similar to the first embodiment but has projections 33a and 33b at the base of the U-shaped body 30. These projections are sized and configured to hold a mini-light.

(17) As can be seen most clearly in FIG. 3, the projections 35, 36, and 37 as well as projections 33a seen in FIG. 2 each preferably consists of a tab portion T connected to the arm 31, 32 by a narrower connector portion C. When a decorative light bulb is inserted into the bulb gripper the narrower connector enables the tab to flex up or down without causing the arm to twist. This is a significant improvement over a bulb gripper in which the projections are replaced by a continuous ledge or a continuous ledge having spaced apart slots like the flanges disclosed in U.S. Pat. No. 5,469,344. The continuous ledge becomes essentially a support rib which makes it too hard for users to push a bulb into the gripper. Furthermore, the arms may twist as the light bulb is inserted. Putting slots in the ledge is only partially effective in reducing rigidity and will not eliminate the twisting or distortion problem that may be encountered when the bulb is inserted between the arms. Also, adding slots would create stress concentrations at the ends of the slots between the flanges.

(18) The bulb gripper can be attached to one of several mounting structures to enable the bulb gripper to be held at a desired location. FIGS. 4, 5 and 6 show the first embodiment of the bulb gripper attached to a stake 1. The stake shown in FIGS. 4, 5 and 6 has a top portion 15 attached to an elongated shaft 2 having a pointed end. The bulb gripper 10 is pivotably attached to the inner surface of the top 15 by a hinge 25 such that the bulb gripper can be moved from a position which is co-linear with a centerline through the stake shown in FIG. 4 to a position which is substantially perpendicular to the centerline through the stake shown in FIGS. 5, 6 and 7. The outer surface of the top portion 15 is curved and may have a series of parallel ribs that run across this surface. This configuration makes it easy to push the device into the ground.

(19) FIG. 10 shows the first embodiment 10 attached to a mounting structure 50 having a slot 52 that is sized to receive the head of a suction cup. The suction cup can be attached to a window or mirror.

(20) FIG. 11 shows the first embodiment 10 attached to a mounting structure 60 which can be attached to a gutter or shingles. The bulb gripper is attached to the mounting structure by a hinge 63. A tab on the top of the bulb gripper can engage a first arm 61 on the housing 60 to hold the bulb gripper in a first locked position. A second tab on the bottom of the bulb gripper can engage a second arm 62 on the housing 60 to hold the bulb gripper in a second locked position.

(21) FIG. 12 shows another embodiment of the bulb gripper 10a, which is similar to the first embodiment of the bulb gripper shown in FIG. 1, attached to another mounting structure 70 that can be attached to siding. In this embodiment the U-shaped mini-light holder 38a is connected to the base 33 of the U-shaped body 30 by a connector. The housing 70 has a hook 72 that can hold a rope light.

(22) Preferably the decorative light holder is made entirely of plastic. We prefer to use polypropylene. But the product could be made of a comparable plastic which permits the arms in the bulb gripper to flex.

(23) Although we have shown and described certain present preferred embodiments of our decorative light holder it should be distinctly understood that our invention is not limited thereto but may be variously embodied within the scope of the following claims.
