For a fuller understanding of the nature of the present invention, reference should be made to the following detailed description taken in conjunction with the accompanying drawings in which:
Like reference numerals refer to like parts throughout the several views of the drawings.
The present invention is directed to a combined doorstop and door holder device, generally indicated as 10, that is particularly suited as a temporary aid during door installation and construction in a high-rise building to prevent interior doors from violently slamming closed as a result of wind forces (e.g., as a result of cross breeze ventilation).
The combined doorstop and holder device 10 is formed as a one-piece integral unit and includes a base 12 that is adapted for temporary mounting to a rough floor surface (e.g., concrete slab) with the use of a conventional fastener, such as a TAPCON concrete screw. A hole 14 is formed through the top side 16 of the base for passage of the fastener therethrough and into the underlying deck surface. When fully inserted and fastened, the head of the fastener becomes seated against the base, and preferably within a counter-sunk bore 18 that extends down into the base. The hole 14 is positioned to minimize the tendency of the base to turn or twist in response to external forces applied to the sides, such as when a swinging door strikes the base. The doorstop and holder further includes oppositely disposed arms 30 that extend outwardly and perpendicularly to opposite side faces 20, 22 of the base 12. An enlarged head 32 formed on the end of each arm has a tapered frontal surface 34 and a rear surface that forms an abrupt shoulder 36. The ends of the arms are reinforced with increased thickness to discourage cracking or breaking when the arms 30 flex and bend in yielding to the force of a door hitting the tapered frontal surfaces 34 of the heads 32. The proximal portions of the arms 30 are provided with increased height, extending to the bottom of the device 10. This further strengthens the arms 30.
The opposite side faces 20, 22 of the base 12 provide an abutment surface for stopping the door 100 before the door or door hardware hit an adjacent wall surface 110. As the door 100 swings open, the lower side edge of the door eventually approaches the doorstop and holder device 10 that is mounted to the floor. The first contact of the door 100 with the device 10 is against the tapered frontal surface 34 of the enlarged head 32 on one of the opposite arms. The tapered frontal surface 34 allows the door to continually swing open, as the lower side edge of the door brushes against the tapered surface on the end of the arm 30. The arms 30 are relatively rigid and resilient, but will flex slightly when yielding to the force of the door brushing against the tapered surface. Once the edge of the door 100 clears the tapered surface, the door continues to move open until it eventually hits the side abutment face 20 or 22 of the base. At this point, the door cannot return to the closed position due to abutting engagement with the abrupt shoulder 36 on the enlarged head. Accordingly, the door is releasably captivated in an open position between the abrupt shoulder 36 and the abutment face 20 or 22 of the base. The taller portion 15 of the base provides higher abutment side faces to accommodate for large clearances between the slab surface and the bottom of the door. This is a common situation that exists before marble or stone is installed on the slab floor surface. The higher abutment face allows the door to hit the base in this instance. The door can be released from the captivated open position by flexing the arm 30 until the shoulder on the rear side of the head is clear from the swinging path of the lower side edge of the door, thereby allowing the door to be swung closed.

The mounting adapter is also provided with male sleeves 44 that extend upwardly from the base plate 42. The male sleeves 44 are specifically sized, structured and configured for sliding receipt within congruently configured cavities on the underside of the doorstop and holder device 10. Thus, the male sleeves 44 insure that the doorstop and holder device 10 is placed squarely in position on the adapter 40 so that, once the device 10 is received on the adapter 40, the two components are held together as an integral unit. When received on the adapter 40, the doorstop and holder device 10 is prevented from twisting relative to the adapter 40. A screw post 46 extending upwardly from the base plate of the adapter is received within the lower portion of the bore 18 on the underside of the doorstop and holder device 10. A screw fastener can then be fitted through the top counter-sunk portion of bore 18 and fastened into the screw post 46 of the mounting adapter 40. This causes the screw post to expand within the lower portion of the counter-sunk bore 18, providing a tight friction fit. When the screw fastener is tightened down into the counter-sunk bore, the doorstop and holder device 10 is held tight onto the mounting adapter 40. Alternatively, screw fasteners can be fitted through the front and back ends of the device 10 and into the sleeves 44 of the adapter (see
When the doorstop and holder device 10 is no longer needed, the adapter 40 can be easily removed with a putty knife or other scraping tool which separates the adhesive without damaging the floor surface. A solvent can then be used on the floor surface to remove any adhesive residue.
While the present invention has been shown and described in accordance with preferred and practical embodiments thereof, it is recognized that departures from the instant disclosure are fully contemplated within the spirit and scope of the invention.
