Description

FIELD OF THE INVENTION

The invention relates to a multifunctional, multipositional hand, mechanical rivet setting device which accomplishes precision setting of aluminum, brass, steel and stainless steel; tubular, semi-tubular and solid rivets having truss, dome and flat rivet heads.

BACKGROUND OF INVENTION

Thousands of products and assemblies, especially those in the consumer durable market, have their components fabricated together with various types of rivets, such as, tubular, semi-tubular and solid rivets made from aluminum, brass steel and stainless steel and having various types of rivet heads, such as, truss, dome and flat heads. Servicing these products and assemblies most often requires drilling out the existing rivets that hold the components together in order to gain access to the areas that need servicing. Primary examples of such products and assemblies are found in the automobile market, especially in the area of classic or historic automobiles dating up through the mid 1980's. Automotive fiberglass heater boxes; metal and felt window channels; metal and plastic air ventilation flaps; and metal and nylon rear axle rebound straps are some examples. After servicing, the components of the assembly must be riveted back together. Hand impact and lever type rivet setting tools are typically single stroke or single motion tools and typically can only function with one type of rivet, such as, tubular or solid; made of only one type of material, such as, aluminum or steel; having only one type of rivet head, such as, truss or flat. In addition, on a functional basis, these tools can only set a rivet from one position within the tool and have difficulty functioning or are unable to function within limited space areas. These riveting tools often mis-set the rivet, damage the rivet shaft or head and most significantly damage the component(s) being riveted together, such as in the case of riveting fiberglass or plastic components. This can result in major repairs to the component(s) or completely discarding the component(s), in turn, resulting in a significant expense. Accordingly, it would be very desirable and extremely beneficial to provide a unique hand, mechanical rivet setting device that would be multifunctional in that it would be able to set various types of rivets, such as, tubular, semi-tubular and solid; being made entirely or in part of aluminum, brass, steel or stainless steel and having various types of heads, such as, truss, dome and flat; that would be multipositional in that it can set rivets from more than one position within the device; that would be able to function within limited space areas; and that would allow the operator to fully control the device so that the rivet would be set with precision, thus eliminating any damage to the rivet or the component(s) being riveted.

SUMMARY OF THE INVENTION

The invention is a hand, mechanical precision rivet setting device uniquely designed and configured to set tubular, semi-tubular and solid rivet types made entirely or in part of aluminum, brass, steel or stainless steel material and having either a truss, dome, or flat rivet head. The device provides for the precision setting of rivets in such a manner so as not to damage or adversely distort the rivet or the components being riveted together. The device is light in weight, of a compact design and can function within restricted space areas. The device comprises a body which has a driveshaft end containing a threaded aperture and a base end containing a threaded aperture; a specially designed driveshaft having a non- threaded aperture for the insertion of one of a multiple number of different tips; a uniquely designed and configured set of non-threaded driveshaft tips for setting rivet shafts and holding rivet heads; and a uniquely designed and configured set of threaded bases for the body providing for setting rivet shafts and holding rivet heads. The device is multipositional in its ability to set rivets, in that a rivet can be set from either the driveshaft end or the base end of the body of the device. The driveshaft is inserted into the threaded aperture of the driveshaft end of the body of the device and partially rotated down. Depending whether the rivet is to be set from the driveshaft end or the base end of the body of the device, either a rivet shaft setting tip or a rivet head holding tip is inserted into the non-threaded aperture of the drive shaft. Correspondingly, either a rivet setting base or a rivet head holding base is inserted into the threaded aperture in the base end of the body of the device and rotated down to a desired position. A rivet is placed into the component to be riveted and the rivet setting device is appropriately placed over the rivet and component so that the rivet head is in position to be held and the rivet shaft is in position to be set. The device driveshaft is rotated down using a socket and ratchet wrench until the rivet shaft is set to the desired configuration. Since the rivet setting process is not dependent on a single impact stroke or lever action, but rather controlled rotation, the device can be removed, multiple times if needed, from the rivet and the rivet can be examined to see if the desired setting configuration has been achieved, and if it has not, the device can be re-positioned over the rivet and component and the rivet setting process can continue until the precise rivet setting configuration is obtained.
