3,064,)33 SELF-LOCKHNQ POLE {IMP Joseph Brasty, Cleveland, Ohio, assignor to D. dc W. Manufacturing (10., line, lChicago, ill. Filed Apr. 25, 196i, Ser. No. P911468 Claims. (Ill. 248-230) This invention relates to a self-locking clip which may be readily applied and removed from a pole, and which may be used for the support of various objects therefrom.

An important feature of the clip of the invention resides in the fact that the gripping effect of the clip increases as the load to be supported by the clip is increased. Such a characteristic makes the clip especially useful since it can be used to support objects differing greatly in weight. Furthermore, the structure of the clip does not require that the pole to which the clip is'applied have any notching, machining, or attachments, the only requisite being that the pole be substantially round, strong and rigid enough to support whatever load is applied to the clip. Another attractive feature of the clip is that it may be easily applied at any vertical level of the pole, in any radial position, and will remain in applied position until removed. An additional feature is that the clip will not mar the pole, thus allowing the position of the clip to be changed whenever desired without leaving tell-tale, or unsightly marks on the pole. Finally, the clip of the invention is a single piece structure which can be readily produced in wire forming machinery, and at low cost.

The main object of this invention is to provide a selflocking clip which may be readily applied and removed from a pole, and which may be used for the support of various objects therefrom.

A more specific object is to provide a self-locking pole clip which has a gripping ef ect that increases as the load on the clip is increased.

Still another object is to provide a self-locking pole clip the structure of which does not require that the pole to which the clip is applied have any notching, machining, or attachments, the only requisite being that the pole be substantially round, strong and rigid enough to support whatever load is applied to the clip.

Another object of the invention is to provide a selflocking pole clip that may be easily applied at any vertical level of the pole, in any radial position, and will remain in applied position until removed.

Still another object is to provide a self-locking pole clip that will not mar the pole on which it has been applied.

A further object is to provide a self-locking pole clip which is a single piece structure that can be readily produced in wire forming machinery and at low cost.

These and further objects and features of the invention will become more apparent fro-m the following description and accompanying drawing wherein:

FIG. 1 is an elevation view showing a pole clip made in accordance with the principles of the invention, as applied to a vertical pole and supporting a potted plant;

FIG. 2 is an elevation view generally as seen from line 2--2 in FIG. 1; and

lFIG. 3 is a plan view of the clip of FIG. 1 in position upon the pole.

Referring now to the drawing, a pole 6 is shown, which pole is preferably made of metal tubing, and is normally supported in vertical position. The pole 6 may be of the type having expansible ends (not shown) whereby the pole may be removably positioned between the floor and ceiling in any desired location in a room. A clip 8 cmbodying the principles of the invention, and preferably made of steel wire, is illustrated in position upon the pole. The clip 8 includes a spiral body portion 10 which extends about the pole substantially one complete revolution, and an integral load supporting, or hook portion 12. The latice ter is formed at the end of an arm portion 14 extending substantially horizontal from the upper end of the body portion 10. The spiral angle of the body portion 10 is preferably within a range of 30 to 40 with the horizontal. While a right hand spiral is shown (viewed from the top of the pole) a left hand spiral would be equally satisfactory. A slight outward turn 16 is arranged at the lower end of the body portion 10. As best seen in FIG. 2, the arm portion 14 and the lower endof the clip are arranged to lie in approximately the same vertical plane.

With reference to FIG. 3, it will be seen that a vertical or axial projection of the body portion Ill, defines a generally elliptical curve, with a minimum inside diameter :1 extending normal to the vertical plane in which the arm portion 14 lays, while a maximum inside diameter 11 extends parallel with said plane. The minimum diameter a is slightly less in length than the outside diameter of the pole 6, so that a snug fit is provided between the clip and the pole.

The pole diameter may be any size desired with the clip being made for a given pole size.

It will be seen in MG. 1, that a load upon the clip, such as produced by a potted plant is suspended from the hook portion i2, will produce a turning moment causing clockwise rotation of the clip. Such clockwise rotation will result in internal diameters of progressively reduced length of the body portion to be brought into contact with the surface of the pole 6. As a result the clip will become clamped with progressively greater force upon the pole as the turning moment loads are increased. Such clamping will result in self-locking of the clip upon the pole to Withstand and support any load suspended from the clip.

It will be appreciated that, while one form of hook portion 12 has been shown, any other type or form may be used which may suspend an object at any desired disstance from the pole. Further, it is to be noted that the clip may be initially applied to the pole by a simple twisting movement, which involves lacing the body portion 1% around the pole with the arm portion in a generally vertical position following which the clip is rotated clockwise iuto final clamped position. Attention is directed to the fact that the clip 8 may be placed upon the pole 6 at any vertical position without the need for bringing the clip over the upper or lower extremities of the pole. Also, the clip will remain in any affixed position without application of a load thereto.

While the clip has been illustrated and described as applied to a vertically arranged pole, it should be obvious that the pole need not necessarily be so oriented. For example, if desired, it would be possible to place a clip 9 upon a horizontally arranged pole with a load force applied to the book 1?. extending in a direction generally parallel to the axis of the pole.

it will be realized that a clip made in accordance with the above description will satisfy the objectives of the invention set forth hereinbefore.

The foregoing description has been given in detail without thought of limitation since the inventive principles involved are capable of assuming other forms without departing from the spirit of the invention or the scope of the following claims.

What is claimed is:

1. A clip for use upon a pole which clip has a spiral body portion and a load supporting portion formed integral with one end of the body portion, said spiral portion being arranged so that an axial projection of the internal diameters thereof will define a generally elliptical curve.

2. A clip for use upon a pole which clip has a spiral I body portion and a load supporting portion formed integral with one end of the body portion, said load supporting portion including a hook means, said spiral portion being arranged so that an axial projection of the internal diameters thereof will define a generally elliptical curve.

3. A clip for use upon a pole which clip has a spiral body portion and a load supporting portion formed integral with one end of the body portion, said spiral portion being arranged to surround the pole substantially one revolution and having a spiral angle of between 30 and 40 relative to the horizontal, said spiral portion being further arranged so that a axial projection of the internal diameters thereof will define a generally elliptical curve.

4. A clip for use upon a pole which clip has a spiral body portion and a load supporting portion formed integral with one end of the body portion, said spiral portion being arranged to surround the pole substantially one revolution and having a spiral angle of between 30 and 40 relative to the horizontal, said spiral portion being further arranged so that an axial projection of the internal diameters thereof will define a generally elliptical curve, said load supporting portion having an arm portion, which lies in the same vertical plane as the lower end of the body portion.

5. A clip for use upon a pole which clip has a spiral body portion and a load supporting portion formed integral with one end of the body'portion, said spiral portion being arranged to surround the pole substantially one revolution and having a spiral angle of between 30 and 40 relative to the horizontal, said spiral portion being further arranged so that an axial projection of the internal diameters thereof will define a generally elliptical curve, said load supporting portion having an arm portion and a hook both of which lie in the same vertical plane as the lower end of the body portion, the minor axis or" said curve being normal to said palne while the major axis is parallel with said plane.
