Abstract
A retaining pin with self biasing keeping means has a head and a tubular pin that has a plurality of detent fingers on its end. The detent fingers are formed by slitting and deforming the ends of the pin. The detent fingers are bent to extend beyond the outside diameter of the pin with the forward ends terminating in a diameter smaller than that diameter. As the pin is inserted in a matched opening, the detent fingers compress to allow the pin to penetrate the opening and then return to their original position to retain them therein. To remove the pin, the process is reversed. The instant retaining pin with self biasing keeping means is conducive to modern mass production methods of production such as cold heading.
Description
- Almost as soon as tools were invented, it became apparent that having a means to keep one part connected to another was very important. Throughout history many solutions to this problem have been found such as pins with cotter pins, retaining rings, clevis pins with cotter pins or detent balls. One of the problems with both cotter pins and retaining rings is that they require an additional part. Additionally, because of this, it is easy to lose the pin or ring requiring obtaining a new one. The clevis pin with detent balls overcomes this limitation since the detent balls are self contained, they are more complex and require a spring and retaining means to keep the detent balls contained.
- There is a need for a simple, easily manufactured retaining pin that solves the problem of securing a connecting pin without the limitation of the prior art.
- A retaining pin with self biasing keeping means has a head and a tubular pin that has a plurality of detent fingers on its end. The detent fingers are formed by slitting and deforming the ends of the pin. The detent fingers are bent to extend beyond the outside diameter of the pin with the forward ends terminating in a diameter smaller than that diameter. As the pin is inserted in a matched opening, the detent fingers compress to allow the pin to penetrate the opening and then return to their original position to retain them therein. To remove the pin, the process is reversed. The instant retaining pin with self biasing keeping means is conducive to modern mass production methods of production such as cold heading.
- Other features and advantages of the instant invention will become apparent from the following description of the invention which refers to the accompanying drawings.
-
FIG. 1 is a side view of a retaining pin with self biasing keeping means according to an embodiment of the invention. -
FIG. 2 is an end view of the retaining pin shown inFIG. 1 according to an embodiment of the invention. -
FIG. 3 is an end view of an alternative embodiment of the pin shown inFIG. 1 . -
FIG. 4 is a side view of a retaining pin with self biasing keeping means according to another embodiment of the invention. -
FIG. 5A is a side view of a retaining pin with self biasing keeping means as it is inserted in a typical part. -
FIG. 5B is a side view of a retaining pin with self biasing keeping means as it is inserted in a typical part showing compression of the detent fingers. -
FIG. 5C is a side view of a retaining pin with self biasing keeping means as it is inserted in a typical part showing the detent fingers returning to a normal position. - In the following detailed description of the invention, reference is made to the drawings in which reference numerals refer to like elements, and which are intended to show by way of illustration specific embodiments in which the invention may be practiced. It is understood that other embodiments may be utilized and that structural changes may be made without departing from the scope and spirit of the invention.
- Referring to
FIG. 1 , a retaining pin with selfbiasing keeping means 100 is shown having apin portion 110 that is a hollow cylinder having an outside diameter and an inside diameter. Ahead 130 is formed at one end to keeppin 110 from moving past a desired position. A plurality ofdetent fingers 120 are provided to provide the biasing means to retainingpin 110 without the need for cotter pins, retaining rings or other detents. - As shown in
FIG. 2 , fourdetent fingers 120 are formed in the end ofpin 110 by slitting and then deforming the ends so that a portion ofdetent fingers 125 extend past the outside diameter ofpin 110. Similarly, fivedetent fingers 120 are shown inFIG. 3 . Of course other numbers of detent fingers can be used depending on the particular application. In general, the smaller the fingers, the less force required to deform them to fit within the selected opening. - Referring now to
FIG. 4 , a retaining pin with self biasing retainer means is shown having ahead 130 andtubular pin 110. In this embodiment, a plurality ofdetent fingers 125 is shown having a profile terminating in a smaller diameter to aid insertion into a part. Again, different profiles may be used without departing from the spirit of the invention and should be realized to be within the scope of this disclosure. - Now referring to
FIGS. 5A through 5C , retainingpin 110 is pressed against an opening 150 in apart 140. As force is applied,detent fingers 125 compress thus reducing the effectivediameter allowing pin 110 to fit within opening 150. Aspin 110 passes through opening 150,detent fingers 125 return to their original non-compressed state and provide biasing to retainpin 110 without further means. To removepin 110, the process is reversed. - Retaining
pin 110 is made of a resilient metal that allows forming such as aluminum or steel. The entire pin may be heat treated to provide the needed flexibility as is known in the art. Additionally, the pin may be heat treated after forming to allow easier manufacturing. Of course other materials may be used such as nylon, etc. as is known in the art as long as the detent fingers are compressible and then return to their original position. Additionally, the detent fingers could be a separate piece or pieces that are attached using a suitable method such as welding. One of the advantages of the present invention is that is can be inexpensively produced in mass production using a process such as cold forging (also known as cold heading). This greatly reduces the cost over many of the prior art retaining pins. - Although the instant invention has been described in relation to particular embodiments thereof, many other variations and modifications and other uses will become apparent to those skilled in the art.
