The present disclosure relates generally to protective devices for entranceways for example, for a building and, more particularly, to protective devices for a door assembly for a residence/facility and to door assembly frame members.
Frame components, such as jambs and mullions, along with thresholds and door panels, are assembled and installed as entranceways in buildings and residences. Door systems are often pre-assembled (pre-hung) in a factory prior to delivery to a job site. Pre-assembly of the frame members is often attempted without the use of guides for location of attachment fasteners. This manual assembly can lead to location errors of fasteners which can compromise joint integrity.
Further, the pre-hung door assembly can be shipped to and stored in multiple locations prior to arrival at the job site. This leads to handling of the door assembly multiple times. The shipping, multiple relocations, and storage of the pre-hung door assembly renders it subject to damage, particularly the bottom-most components which include side jambs.
Some efforts have been made to provide protective devices for the bottom-most components, however, such efforts have been directed toward permanently attached structures for placement during installation, protective devices that do not adequately protect the frame parts, create unacceptable expense, or hinder installation and cause excessively long processing times. Conventional devices, by way of example, strips of wood and/or, heavy duty cardboard do not assist with proper placement of components during the assembly process.
Thus, Applicant recognized there remains a need for a new and improved protective device for door assemblies and frame members and it is to these and other challenges that the inventions of the present disclosure are directed.
The present disclosure is directed in one embodiment to a protective support for a door frame member. One embodiment may include a protective support device for attachment to the bottom of a door frame member including a body portion and an adjoining flange portion. The body portion may include a free side and a corner side running parallel to each other and to an Axis A. The body portion may adjoin the flange portion along the corner side. One example may include at least one longitudinal guide slot spanning from a back of the flange through to a front of the flange. An opening in the flange may be provided and configured to serve as a guide for placement of a fastener through the openings. The support device in some embodiments is configured to mate with the door frame member at a corner and is removed prior to installation.
In some examples, the protective support device body portion may include a top and a bottom. The top may include a substantially planar surface. The bottom may include a substantially curved surface. The substantially planar surface may include recesses. The recesses may recess into the substantially planar surface. The substantially curved surface may also include recesses into the inside of the substantially curved bottom.
The bottom may include a first ramped end and a second ramped end. The bottom may extend longitudinally between the first and second ramped ends. The bottom may extend away from the substantially planar surface to form an apex along the most distal part of the substantially curved bottom.
The first and second ramped ends may be tapered toward each other and away from a respective first bottom end and a second bottom end.
In some embodiments, the support device may form an L-shaped support sized to mate with the bottom end of a side jamb. The support deice body may include a planar top portion and an arced bottom portion with a set of tapered ends that taper inwardly toward one another.
Other embodiments may include a protective support device for attachment to the bottom of a door frame side jamb including a body portion and an adjoining flange portion. The body portion may include a free side, a corner side, a first end, a second end, a top and a bottom. The free side and the corner side may run parallel to each other and to an Axis A. The body portion may adjoin the flange portion along the corner side. The top may have a substantially planar surface. The bottom may include ramped ends at the first end and at the second end. There may be a radiused surface between the ramped ends. The flange portion may include at least one guide slot spanning from a back of the flange through to a front of the flange. There may be an opening in the flange configured to serve as a guide for placement of a fastener through the openings.
Inward recesses in the radiused surface may form an attachment area for temporarily securing the support device to the door frame side jamb. The recesses may be a reduced portion. The attachment area may include a flat surface between the top and the bottom on which fasteners may be secured and the fasteners may pass through to secure the support device to the door frame side jamb.
Examples may include a protective device for a door assembly. The protective device for a door assembly may include any of the embodiments disclosed herein. The protective device may be fitted with the bottom-most components of a pre-hung door system to protect the frame members and assembly during shipping, transport and storage.
Inventions of the present disclosure may also be considered a method for protection of a door frame member by way of any of the embodiments disclosed. By way of example, a method for protection of a door frame member may include mating an L-shaped protective support device having a body portion and an adjoining flange portion to a bottom end of a door frame member, aligning the flange portion with an outside end of frame member, aligning the body portion with a lower end of the frame member, securing the support device to the door frame member with a detachable fastener, leaving the protective support device affixed during transport of a pre-hung door assembly, and removing the support device prior to installation of the door assembly into a rough opening.
A guide slot may be used to position fasteners to attach the frame member to a threshold prior to removal of the support device. The lower end of the frame member may be covered with a curved bottom of the body portion.
These and other aspects of the inventions of the present disclosure will become apparent to those skilled in the art after a reading of the following description of embodiments when considered with the drawings.

One embodiment may include the protective support device 10 for attachment to the bottom of a door frame member including a body portion 12 and an adjoining flange portion 22. The body portion 12 may include a free side 17 and a corner side 19 running parallel to each other and to an Axis A (see
Some embodiments may include more than one guide slot. Guide slots may include, by way of example, a mid-guide slot 28 and/or one or more end guide slot 26. One example includes an elongated end guide slot 26 providing an opening toward one end of the flange, an elongated end guide slot 26 toward a distal end of the flange and a mid-guide slot 28 arranged in line with and between the two end guide slots 26, with each of the guide slots 26, 28, 26 spaced apart from each other by portions of the flange 22. The support device 10 in some embodiments is configured to mate with the door frame member at a frame member corner and is removed from the frame member corner prior to installation.
The flange 22 guide slots 26, 28 may indicate proper position for fasteners used to attach side jambs to a sill/threshold. Fasteners may typically include crown-type staples, by way of example, but could also include screws, and/or nails. Fasteners may be used through the flange 22 and/or through the guide slots 26, 28 to attach the support device 10 to a jamb side face prior to door unit assembly. The support device 10 may be sized for accurate placement and coverage on the bottom end of a door jamb.
Embodiments may include where the protective support device body portion 12 may include a top 12A and a bottom 12B. The top 12A may include a substantially planar surface. The bottom 12B may include a substantially curved surface. The substantially planar surface may include recesses 25. The recesses 25 may recess into the substantially planar surface. The substantially planar surface may be a framework including a frame having recesses 25 inlaid in the frame.
The substantially curved surface may also include recesses into the inside of the substantially curved bottom 12B. The recesses in the substantially curved bottom may be considered reduced portions 20. The reduced portions 20 may include openings and/or may be portions reduced and recessed into the substantially curved bottom. The reduced portions 20 may include cutaways recessed into the substantially curved bottom at approximately a 90 degree angle. The cutaways may be at between an 85 degree and 95 degree angle in some examples. The reduced portions 20 may be recessed on the bottom 12B and may form planar faces 27 on the top 12A to be apart of the planar surface.
The bottom 12B may include a first ramped end 14 and a second ramped end 14. The ramped ends may terminate the bottom 12B on each end. The ramped ends 14 may face away from each other at distal ends of the bottom 12B. The bottom 12B may extend longitudinally between the first and second ramped ends 14. The bottom 12B may extend away from the substantially planar surface to form an apex along the most distal part of the substantially curved bottom. An axis A may run along the apex.
The first and second ramped ends may be tapered toward each other and away from a respective first bottom end and a second bottom end. The ramped ends and substantially curved surface of bottom 12B facilitate ease of overcoming encountered obstacles, reduced friction against obstacles and encourage the frame member to slide smoothly across encountered obstacles without damage to the frame member during door assembly transportation, handling prior to installation.
In some embodiments, the support device 10 may form an L-shaped support sized to mate with the bottom end of a side jamb frame member 40 as seen in

The body portion may include a free side 17, a corner side 19, a first end, a second end, a top 12A and a bottom 12B. The free side 17 and the corner side 19 may run parallel to each other and to an Axis A. The body portion 12 may adjoin the flange portion 22 along the corner side 19. The top 12A may have a substantially planar surface. The bottom 12B may include ramped ends 14 at the first end and at the second end. There may be a radiused surface 16 between the ramped ends. The flange portion 22 may include at least one guide slot 28 spanning from a back 22B of the flange 22 through to a front 22A of the flange. There may be an opening in the flange configured to serve as a guide for placement of a fastener through the openings.
Inward recesses in the radiused surface 16 may form an attachment area 20 for temporarily securing the support device 10 to a door frame side jamb. The attachment area 20 may be a reduced portion. The attachment area 20 may include a flat surface between the top 12A and the bottom 12B on which fasteners may be secured and the fasteners may pass through to secure the support device 10 to a door frame side jamb.
The radiused surface 16 may be divided by the reduced portions 20. There may be a middle radiused surface 18 and end radiused surfaces 16. The radiused surfaces 16, 18 may be separated by the reduced portions 20 in some examples.
An embodiment may be considered a protective device 10 for a door assembly. The protective device 10 for a door assembly may include any of the embodiments disclosed herein. The protective device may be fitted with the bottom-most components of a pre-hung door system to protect the frame members and assembly during shipping, transport and storage.
Inventions of the present disclosure may also be considered a method for protection of a door frame member by way of any of the embodiments disclosed. By way of example, a method for protection of a door frame member may include mating an L-shaped protective support device having a body portion 10 and an adjoining flange portion 22 to a bottom end of a door frame member, aligning the flange portion 22 with an outside end of frame member, aligning the body portion 12 with a lower end of the frame member, securing the support device 10 to the door frame member with a detachable fastener, leaving the protective support device affixed during transport of the door assembly, and removing the support device 10 prior to installation of the door frame member into a rough opening.
