Abstract

A door holder and release assembly that is adjustable to account for different differences between the door and where the door holder and release assembly will be installed (e.g., a wall, the floor, another support location). The door holder herein has a base member, a holder member, and a connector. The base member may be configured for operative coupling with a wall or a door. The holder member may be configured for operative coupling with a release assembly on the wall or the door opposite the base member. Moreover, the holder member may be configured to be telescopically operatively coupled with the base member through the connector to position the holder member at varied distances from base member to allow for the accommodation of varying distances between a wall and the door, as well as for minor adjustments that a user may want to make.

Claims (33)

1. A door holder comprising:

a base member having a proximal base end and a distal base end, wherein the proximal base end is configured to be operatively coupled with a wall or a door; and wherein the distal base end of the base member comprises a base aperture and external threads;

a holder member having a proximal holder end and a distal holder end, wherein the proximal holder end is a shaft with an internal threaded shaft aperture;

a shaft extender having a threaded extender projection at a distal extender end with a projection width that is less than a shaft extender width, wherein the shaft extender is operatively coupled to the shaft through the extender projection located completely within the internal threaded shaft aperture, and wherein an outer surface of the shaft extender and the outer surface of the shaft meet to increase a length of the shaft, wherein a proximal extender end is configured to define an internal threaded aperture for receiving an additional shaft extender when necessary;

a connector comprising a collar having internal threads for operatively coupling the proximal holder end of the holder member to the distal base end of the base member; and

a compression member, wherein the compression member is located at least partially around the shaft or the shaft extender when the shaft extender is used;

wherein the proximal holder end is configured to be telescopically operatively coupled with the base member through the connector by sliding the shaft or the shaft extender within the base aperture to position the distal holder end at different distances from the proximal base end of the base member; and

wherein the internal threads of the collar are operatively coupled to the external threads of the distal base end of the base member and configured to compress the compression member to operatively couple the shaft or shaft extender to the base member.

2. The door holder of claim 1 , wherein the distal holder end of the holder member is configured to be removably operatively coupled with a release member that is operatively coupled to the wall or the door opposite of the base member.

3. The door holder of claim 2 , wherein the release member is an electromechanical release.

4. The door holder of claim 1 , wherein the proximal holder end and the distal holder end are operatively coupled to each other with one or more degrees of freedom.

5. A door holder and release assembly comprising:

a release member that is operatively coupled to a wall or a door;

a base member having a proximal base end and a distal base end, wherein the proximal base end is operatively coupled with the wall or the door opposite the release member, and wherein the distal base end of the base member comprises a base aperture and external threads;

a holder member having a proximal holder end and a distal holder end, wherein the proximal holder end is a shaft with an internal threaded shaft aperture;

a shaft extender having a threaded extender projection at a distal extender end with a projection width that is less than a shaft extender width, wherein the shaft extender is operatively coupled to the shaft through the extender projection located completely within the internal threaded shaft aperture, and wherein an outer surface of the shaft extender and the outer surface of the shaft meet to increase a length of the shaft, wherein a proximal extender end is configured to define an internal threaded aperture for receiving an additional shaft extender when necessary;

a connector comprising a collar having internal threads for operatively coupling the proximal holder end of the holder member to the distal base end of the base member; and

a compression member, wherein the compression member is located at least partially around the shaft or the shaft extender when the shaft extender is used;

wherein the proximal holder end is telescopically operatively coupled with the base member through the connector by sliding the shaft or the shaft extender within the base aperture to position the distal holder end at different distances from the proximal base end of the base member;

wherein the internal threads of the collar are operatively coupled to the external threads of the distal base end of the base member to compresses the compression member to operatively couple the shaft or shaft extender to the base member; and

wherein the distal holder end of the holder member is removably operatively coupled with the release member.

6. The door holder and release assembly of claim 5 , wherein the release member is an electromechanical release.

7. The door holder and release assembly of claim 5 , wherein the proximal holder end and the distal holder end are operatively coupled to each other with one or more degrees of freedom.

8. A method of installing a door holder, the method comprising:

installing a base member having a proximal base end and a distal base end to a door or a wall, wherein the distal base end of the base member comprises a base aperture and external threads;

installing a shaft extender to a shaft of a holder member, wherein the holder member comprises a proximal holder end and a distal holder end, wherein the distal holder end is the shaft having an internal threaded shaft aperture, wherein the shaft extender has a threaded extender projection at a distal extender end with a projection width that is less than a shaft extender width, and wherein the shaft extender is operatively coupled to the shaft through the extender projection located completely within the internal threaded shaft aperture, and wherein an outer surface the shaft extender and the outer surface of the shaft meet to increase a length of the shaft, wherein a proximal extender end is configured to define an internal threaded aperture for receiving an additional shaft extender when necessary;

installing the holder member to the base member by telescopically sliding the shaft or the shaft extender within the base aperture to position the distal holder end at a distance from the proximal base end of the base member;

installing a compression member at least partially around the shaft or the shaft extender when the shaft extender is used; and

installing a connector comprising a collar having internal threads for operatively coupling the proximal holder end of the holder member to the distal base end of the base member;

wherein the internal threads of the collar are operatively coupled to the external threads of the distal base end of the base member to compress the compression member to operatively couple the shaft or shaft extender to the base member.

9. The method of claim 8 , wherein the distal holder end of the holder member is configured to be removably operatively coupled with a release member that is operatively coupled to the wall or the door opposite of the base member.

10. The method of claim 9 , wherein the release member is an electromechanical release.

11. The method of claim 8 , wherein the proximal holder end and the distal holder end are operatively coupled to each other with one or more degrees of freedom.
