  • Joint structure for synthetic resin structural members
    Patent number: 5503493
    Abstract: Synthetic resin structural members are inserted into a hollow joint member to abut each other in the joint member. A bearing-pressure damping member is fitted into each of bolt holes on the members, axes of bolts extend alternately in two mutually perpendicular directions. The structural members and the hollow joint member are secured with bolts and nuts. Due to damping action resulting from elastic deformations of the damping members, a load is substantially evenly distributed over the whole bolts to prevent concentration of the load to some of the bolts. The arrangement of the bolts with their axes extending alternately in two mutually perpendicular directions will shorten the length of the joint member.
