The disclosure relates generally to restraining items from moving, and specifically to devices that restrain a door.
Some doors are biased toward a closed position where the door will automatically close once a user no longer exerts an opening force on the door. When a user desires to restrain the door in an open position, the user may select a door prop that rests on the floor. However, ingress and egress through the doorway may result in inadvertently moving the door prop, resulting in undesirably permitting the door to close. If the door closes while a user or cargo is in the path of the door swing, the door, and/or cargo may be damaged. Examples of cargo that may be particularly sensitive to an inadvertent door impact include wedding cakes and glassware. Further, a user may be injured.
What is needed is a device to restrict movement of a door toward a closed position. A desirable device would allow workers to be more efficient by being able to quickly and effortlessly control the door. Other doors that do not have a mechanism to urge the door to a closed position may also be desired to have a device that will restrict door movement toward the closed position.
The drawings are illustrative embodiments. The drawings are not necessarily to scale and certain features may be removed, exaggerated, moved, or partially sectioned for clearer illustration. The embodiments illustrated herein are not intended to limit or restrict the claims.
The hinge 26 includes a door member 50, a jamb member 52, and a shaft 54 generally defining an axis A-A. As is known, the door 22 rotates in a first rotational direction C and in a second rotational direction D relative the hinge jamb 24 generally about the axis A-A.
As best seen in
In the embodiment illustrated, the doorprop 60 also includes a first extending portion 82 a second extending portion 84, a door inner edge 86, and a jamb inner edge 88. In the embodiment illustrated, the doorprop 60 further includes an aperture 90 formed therein generally defined by an inside surface 92 and an axis B-B (
In an embodiment, the door face surface 68 is generally parallel to the jamb trim face surface 78, and the door contacting surface 70 is generally parallel to the jamb trim edge surface 76. In the embodiment illustrated, the first door transition surface 72 is curved to reduce the occurrences of an item inadvertently contacting the doorprop 60 as a user goes through the doorway.
As best seen in
When the door 22 is urged in the first rotational direction C, the first door side surface 30 is moved toward the door edge abutting surface 40. As the door 22 is urged in the first rotational direction C, a portion of the body 62 is compressed between the first door side surface 30 and the door edge abutting surface 40. In the embodiment illustrated, the body 62 of the doorprop 60 will deform such that the door contacting surface 70 will move toward the jamb trim face surface 78.
When the door 22 is urged in the second rotational direction D, the first door side surface 30 is moved away from the door edge abutting surface 40. As the door 22 is urged in the second rotational direction D, the first extending portion 82 of the body 62 may be compressed between the first door face 32 and the hinge jamb edge 46.
In one embodiment, the doorprop 60 is injection molded of a recycled vulcanized rubber, although other materials may be used as desired. The doorprop 60 may be illustrated in
In another embodiment, the doorprop 60 is constructed of a recycled vulcanized rubber and the door 22 is biased to move in the first direction C by a spring or other mechanism. This biasing of the door 22 will compress the body 62, thereby retaining the doorprop 60 in position.
In the embodiment illustrated, the doorprop 120 also includes a first extending portion 142 a second extending portion 144, a door inner edge 146, and a jamb inner edge 148. In the embodiment illustrated, the doorprop 120 further includes an aperture 150 formed therein generally defined by an inside surface 152 and an axis E-E. The aperture 150 may be oval, elliptical circular, or any desired shape. As best seen in

When the door 22 is urged in the first rotational direction C, the first door side surface 30 is moved toward the door edge abutting surface 40. As the door 22 is urged in the first rotational direction C, a portion of the body 122 is compressed between the first door side surface 30 and the door edge abutting surface 40. In the embodiment illustrated, the body 122 of the doorprop 120 will deform such that the door contacting surface 130 will move toward the jamb trim face surface 138.
When the door 22 is urged in the second rotational direction D, the first door side surface 30 is moved away from the door edge abutting surface 40. As the door 22 is urged in the second rotational direction D, the first extending portion 142 of the body 122 may be compressed between the first door face 32 and the hinge jamb edge 46.
To install the doorprop 120, a user may interpose the first extending portion 142 between the door 22 and the hinge jamb 24 and then lower the doorprop 120 until the doorprop 120 contacts a hinge 26.
The apertures may permit the doorprop to compress such that damage to the door assembly is avoided. Further, the apertures, friction between the doorprop and the door assembly, and resilient construction of the doorprops permit the contacting surfaces between the doorprop and the doorway to remain in contact when the door is moved, thereby preventing the doorprop from falling from position. Further, dimensions of the doorprop, such as the thickness (distance between the upper surface and lower surface) and the dimensions of the aperture may be varied, as desired, to accommodate differing door assemblies. Still further, the rigidity of the doorprop may be varied as desired.
While in the embodiments illustrated above the apertures have ambient air therein, the apertures 90, 150 may have a resilient member interposed therein. In an embodiment, the resilient member completely fills the aperture. Further, the resilient member may be formed of a material that is more resistant to compression that the material of the doorprop, or may be formed of a material that is less resistant to compression that the material of the doorprop. When a resilient material such as rubber is used for the doorprops, the apertures may be filled with air or any material that is less dense than the rubber.
The preceding description has been presented only to illustrate and describe exemplary embodiments of the methods and systems of the present invention. It is not intended to be exhaustive or to limit the invention to any precise form disclosed. It will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the claims. The invention may be practiced otherwise than is specifically explained and illustrated without departing from its spirit or scope. The scope of the invention is limited solely by the following claims.
This application claims priority to U.S. Provisional Application 61/143,479, filed on, 9 Jan. 2009, the disclosure of which is hereby incorporated by reference in its entirety.
