Seat attachment apparatus

Abstract

An apparatus for attaching a seat to a seat post comprises a cylindrical housing with oppositely oriented openings on the side of the housing. Top and bottom clamping pieces are positioned through the openings. Mating grooves on the ends of the clamps are adapted for placement and securing of a pair of rails affixed to the underside of the seat. A bottom block is disposed beneath the clamps and adapted for abutment against the clamps. The interior bottom portion of the housing is threaded, and the exterior top portion of the seat post is threaded for engagement with the threads of the housing, so that the seat post itself is tightened against the bottom piece, thus securing the seat rails within the clamps without need for tools or small components.

Description

FIELD OF THE INVENTIONThe present invention relates to an apparatus for attaching a seat to a seat post or frame, particularly bicycle seat posts and frames.BACKGROUND OF THE INVENTIONMost bicycle seat assemblies have two rails extending underneath the seat from back to front, to which the post attaches and tightens by means of variously shaped housings and tightening bolts. The post in turn is placed in the bicycle frame, and adjusted vertically by sliding the post up or down within the frame. It is adjusted forwardly and rearwardly by loosening the attachment of the post to the rails and moving the rails through the post attachment forwardly or rearwardly as desired.Prior art seat / post attachments, especially those with tilting capability, often employ numerous small parts which constitute a weakness in construction. Besides making the apparatus more complex and thus expensive, small parts such as bolts can and often do fail due to improper assembly, e.g. overtightening, poor main...

AI Technical Summary

Benefits of technology

It is an object of the invention to provide a seat / post attachment apparatus whose construction is relatively simple and which is relatively quick and easy to adjust.

It is a further object of the invention to provide a seat / post attachment apparatus which minimizes or eliminates the need for small bolts or other hardware for securing the attachment apparatus to the seat.

It is an additional object of the invention to provide a seat / post attachment apparatus which minimizes or eliminates the need to use tools for position adjustment.

It is still another object of the invention to provide a seat / post attachment apparatus which minimizes or eliminates the risk of accidental rotation while the seat is in use.

Problems solved by technology

Prior art seat / post attachments, especially those with tilting capability, often employ numerous small parts which constitute a weakness in construction.

Besides making the apparatus more complex and thus expensive, small parts such as bolts can and often do fail due to improper assembly, e.g. overtightening, poor maintenance, or simply fatigue induced through work hardening.

Another problem with seat / post attachment apparatus is complexity of adjustment.

Since the seat / post attachments are difficult to adjust, many customers take delivery of bicycles that are not correctly adjusted for their physiques, resulting in inefficient and uncomfortable riding, and this increases the likelihood of fatigue and failure of small parts.
