length of the handle on the reverse side the narrow portion of the clamp is placed behind the handle and over top of the raised portion on the rear edge of the handle there is sufficient tension on the clamp to keep the clamp attached to the handle during the pull the spring tension is sufficient in almost all cases to prevent the clamp from sliding over the raised edge of the handle and disengaging the larger rounded portion of the clamp provides a larger surface friction on the front of the handle surface and helps keep the clamp from sliding or twisting during normal pulls the pull is kept substantially perpendicular to the door handle since it is only the substantial spring tension which holds the clamp in place 0073 fig3 and 33 illustrate a locking car door pull which is designed as a universal hinged car door handle attachment which can be manually locked on the handle by turning the threaded eye bolt on the end there are instances where there is a misalignment of the car door on its frame which makes it difficult to open the door by pulling even after the door mechanism has functioned correctly this misalignment can cause the clamp of fig3 and 31 to break away from the door handle when the pull is particularly difficult since it is only held in place by the spring tension in these situations the clamp of fig3 and 33 can be forcefully attached so that it will not slide off during the pull the flat portion of the clamp is placed behind the door handle taking advantage of the raised portion of the handle this raised edge is present on the reverse side edge of all door handles of this type.
