It is a further object and purpose of the present invention to provide an adjustable door stop system that may be readily and quickly adjusted to adjust the permissible opening of the door with respect to the doorway.
The present invention is directed to an adjustable door stop system. The system includes a hinge pin with a cylindrical barrel having an axis so that hinge leaves rotate around the axis.
A hinge pin cap extends from and is attached to a top end of the hinge pin. The hinge pin cap has a first portion extending radially from the top end of the hinge pin perpendicular to the axis of the hinge pin. The hinge pin cap also includes a second cylindrical portion extending from the first portion parallel to the axis of the hinge pin. The second portion does not completely encircle the hinge pin so that the edges form shoulders.
A control cap includes a central opening to receive the hinge pin therethrough. The control cap also includes a first portion radially extending from the central portion and a second portion extending cylindrically from the first portion wherein the second portion is substantially parallel to the axis of the hinge pin. The second portion does not completely encircle the hinge pin so that the edges form shoulders.
A mechanism is provided to prevent movement of the hinge pin cap with respect to the control cap. A plurality of teeth on the inside surface of the hinge pin cap second cylindrical portion engage and mate with a plurality of teeth on the exterior surface of the control cap cylindrical portion.
The hinge pin cap and the control cap operate together to stop and arrest movement of the door at a desired, selected position prior to either the door or an adjacent wall or doorway being marred.
The embodiments discussed herein are merely illustrative of specific manners in which to make and use the invention and are not to be interpreted as limiting the scope of the instant invention.
While the invention has been described with a certain degree of particularity, it is to be noted that many modifications may be made in the details of the invention's construction and the arrangement of its components without departing from the spirit and scope of this disclosure. It is understood that the invention is not limited to the embodiments set forth herein for purposes of exemplification.
One hinge leaf 12 would be connected to a door 14 in a known manner, such as with fasteners. Another hinge leaf 16 would be connected to a doorway 18 in a known manner, such as with fasteners. The present invention may be employed with a wide variety of doors and doorways.
The adjustable door stop system includes a hinge pin 22 with a cylindrical barrel having an axis (illustrated by dashed lines 24 in
The hinge pin cap 30 has a first portion 32 extending radially from the top end of the hinge pin. Accordingly, the first portion 32 is perpendicular to the axis 24 of the hinge pin. The hinge pin cap 30 also includes a second cylindrical portion extending from the first portion 32 parallel to the axis of the hinge pin 22. The second portion does not completely encircle the hinge pin 22 so that the edges form shoulders.
A control cap 40 includes a central opening to receive the hinge pin 22 therethrough. The control cap 40 also includes a first portion radially extending from the central opening and a second portion extending cylindrically from the first portion wherein the second portion is substantially parallel to the axis of the hinge pin 22. The second portion does not completely encircle the hinge pin 22 so that the edges form shoulders.
The diameter of the second portion of the hinge pin cap 30 is slightly larger than the diameter of the second portion of the control cap 40.
A mechanism is provided to prevent movement of the hinge pin cap 30 with respect to the control cap 40. A plurality of teeth on the inside surface of the hinge pin cap 30 second cylindrical portion are provided. A plurality of teeth are also provided on the exterior surface of the control cap 40 cylindrical portion so that the teeth engage and mate with each other.
The hinge pin cap 30 and the control cap 40 operate together to stop and arrest movement of the door 14 at a desired, selected position prior to either the door or the adjacent wall or doorway being marred.

It will be appreciated that in an alternate arrangement (not shown), the control cap 40 would engage the hinge leaf 16 connected to the doorway 18 while the hinge pin cap 32 would engage the hinge leaf 12 connected to the door 14.
Returning to a consideration of
A plurality of slots generally parallel to the axis 24 of the hinge pin 22 are provided in the bottom end of the hinge pin 22 extending through. The bottom end, accordingly, may be compressed to allow reduction of the enlarged portion during installation of the hinge pin 22 through the hinge leaves. The bottom end is resilient and, once installed, the radially enlarged portion returns to its normal diameter. Accordingly, the hinge pin 22 will resist being removed from the hinge leaves after installation.
In order to utilize the adjustable door stop system 10 of the present invention, the hinge pin 22 having the hinge pin cap 30 at the top thereof is inserted through the opening in the control cap 40 so that the barrel of the hinge pin 22 is received through the opening of the control cap 40. The teeth of the hinge pin cap will mate with the teeth of the control cap 40 in a selected position to allow the door 12 to open a desired distance.
The bottom end of the hinge pin 22 is then inserted through the hinge leaves 12 and 16.
One hinge leaf 52 would be connected to the door 54 while another hinge leaf 56 would be connected to a doorway 58.
