The present invention is directed to a door stop device, preferably a portable door stop device.
There exist a number of different types of door stops configured to maintain a door in an open position. For example, there exists a stand alone rubber wedge-shaped door stop that can be wedged between the floor and the lower edge of the door to maintain the door open. Further, there exists a door stop that is permanently mounted to the bottom of the door (i.e. not portable), and stays with the door throughout the life of the door.
There exists a need for an improved door stop device, in particular a portable door stop device to facilitate cleaning and maintenance of commercial or institutional buildings. In a preferred embodiment, the door stop device can be easily and conveniently installed prior to cleaning, and then later removed after cleaning. Further, it is desirable that such a door stop can be installed and removed in a manner to minimize the user bending over during installation or removal. Even further, it is even more desirable that such a door stop can be installed and removed in a manner to eliminate the user bending over during installation or removal.
The first object of the present invention is to provide an improved door stop device.
A second object of the present invention is to provide an improved portable door stop device.
A third object of the present invention is to provide a door stop device having a substantially long handle to minimize the user bending over to install or remove the door stop device.
A fourth object of the present invention is to provide a door stop device having a substantially long handle to eliminate the user bending over to install or remove the door stop device.
A fifth object of the present invention is to provide a door stop device including a handle having a lower door gripping finger, and a pivotable leg portion configured to secure the door stop device from movement with the floor.
A sixth object of the present invention is to provide a door stop device including a handle having a lower door gripping finger combined with a pivotable leg portion, the leg portion being adjustable in length.
A seventh object of the present invention is to provide a door stop device including a bent handle portion having a lower door gripping finger, and a pivoting leg portion, the pivoting leg portion being a telescoping leg portion.
The present invention is directed to an improved door stop device, preferably an improved portable door stop device.
A preferred embodiment of the door stop device according to the present invention includes a handle portion provided with a pivoting leg. The handle portion is preferably an elongated (i.e. long) handle portion having an upper handle portion and a lower handle portion. The lower handle portion is provided with a lower door edge gripping portion (e.g. door gripping finger). In a preferred embodiment, the handle portion is bent so that the lower handle portion can be positioned flat against the side of the door, and the upper handle portion bends away from the door to facilitate gripping by a user. The lower door gripping portion of the handle, for example, can be a door gripping finger or extension provided at the lower end of the handle portion. For example, the handle portion is made of a flat metal strip, and a short finger portion (e.g. one-quarter inch to two inch) is made by bending the metal strip near the bottom thereof. The finger portion can be provided with a resilient plastic or rubber cover to enhance the frictional engagement with the lower edge of the door.
In a preferred embodiment, the upper handle portion is provide with or defines a hand grip for the user. The hand grip is preferable configured to allow a user's hand to grab the hand grip (e.g. user's hand wraps around the hand grip). For example, a user grips the hand grip with the user's thumb located on one side of the hand grip and the user's fingers on the opposite side of the hand grip. The upper handle portion can be configured to provide a hand grip, or a separate hand grip can be attached to the upper handle portion (e.g. rubber or plastic hand grip fitted over end of the upper handle portion).
The door stop device includes a pivoting leg connected to the handle portion. The pivoting leg is preferably adjustable in length so that the door stop device can accommodate different doors throughout a building having different size doors or different size gaps between the floor and a lower edge of the various door. A lower end of the pivoting leg is preferably provided with a rubber stop or cover to enhance the frictional grip of the lower end of the pivoting leg with the floor, for example, to facilitate locking the door stop device in place against the face of a door. In a preferred embodiment, the pivoting leg includes an upper U-shaped bracket connected to the back of the plate handle (e.g. by welding), and a pin passing through an upper end of the pivoting leg and the bracket to provide a pivoting connection therebetween. The leg portion can be made as to be telescoping to make it adjustable in length. For example, the leg portion can be made of a lower tubular section slidably disposed within an upper tubular section. The upper tubular section can be provided with a series of vertical through holes and the lower tubular section can be provided with a spring biased pin configured so as to lock in one of the through holes in the upper tubular section. In this manner, the length of the pivoting arm can be adjusted and then lock in place.
The door stop device according to the present invention can be made of metal, plastic, fiberglass, graphite, carbon, wood, wood filled, glass filled, composite, or other suitable material. In one preferred embodiment, the handle portion is made of a flat strip of aluminum plate.
In a preferred embodiment, a lower end of the aluminum strip is bent at approximately ninety degrees (90°) to form the door gripping finger or portion, and the metal strip is bent approximately ten degrees to forty-five degrees (10° to 45°) at or near the center thereof so that the upper handle portion of the metal strip extends away from the door when the door stop is installed up against the face of the door to facilitate a user gripping the upper handle portion of the handle portion. The upper handle portion is provided with at least one through hole for hanging the door stop from a wall or custodian cart. Further, to lighten the handle, the upper portion of the aluminum plate can be drilled with a plurality of through holes to reduce material and weight while still being sufficiently strong to serve as a handle. In this same embodiment, the pivoting leg can be made of an aluminum bracket, an upper aluminum tubing section, and a lower aluminum tubing section slidably disposed within the upper aluminum tubing section. A rubber foot can be provided at the bottom of the lower aluminum tubing section. The movable locking pin is preferably made of steel to increase the strength of the pivot connection.
Another preferred embodiment of the door stop device according to the present invention can be made of plastic material, in particular plastic resin. This embodiment can be made by injection molding a portion, or the entire door stop device. For example, the handle portion can be plastic injection molded as one piece, and the pivoting leg can be molded as two (2) separate piece assembled together as a telescoping leg. The assembled pivoting leg can then be assembled to the handle portion.
A preferred embodiment of a door stop device 10 according to the present invention is shown in
The door stop device 10 includes a handle 12 provide with a pivoting leg 14. The handle 12 includes an upper handle portion 12a connected to a lower handle portion 12b. The pivoting leg 14 is configured to be a telescoping leg, and includes an upper leg section 14a and a lower leg section 14b. The lower leg section 14b is slidably disposed within the upper leg section 14a.
An upper portion of the upper handle portion 12a provides a hand grip for a user, as shown in
The handle 12 is provided with a door gripping finger 16 located at the bottom of the lower handle portion 12b. Further, the handle 12 is bent at axis or point 18 so that the upper handle portion 12a bends away from the door when the lower handle portion is placed against the door (See
The handle 12 can be made of metal, plastic, fiberglass, carbon fiber, composite or other suitable material. For example, the handle 12 is made from a flat plate of aluminum cut to shape (e.g. aluminum strip), and bent at axis or point 18 so that the upper handle portion 12a bends away from the lower handle portion 12b. The aluminum plate is also bent at axis or point 20 (e.g. 90 degrees) to form the door gripping finger 16. Alternatively, the handle 12 is injection molded from plastic resin, in particular glass filled plastic resin to enhance strength, durability, and performance of the handle 12.
The pivoting leg 14 is connected to the handle 12 by a bracket 24 and pin 26 (
For example, the pivoting leg 14 is made out of sections of aluminum tubing with the upper leg portion 14a having a larger diameter than the lower leg section 14b (
Alternatively, the bracket 24 is injection molded with plastic resin as part of the handle 12, and the pivoting leg sections 14a, 14b are injection with plastic resin as separate pieces, and then assembled together. The assembled pivoting leg is then assembled to the handle 12.
As shown in
During use, the user installs the door stop device 10 against the door D to be maintained open, as shown in
The length of the handle 12, in particular the upper hand portion 12a, is sufficiently long so that the user preferably minimally bend, or more preferably does not have to bend, to install or remove the door stop device from the door D. In this manner, the door stop device 10 can be easily and quickly installed or removed with minimal effort and time by the user greatly increasing the convenience of the door stop device 10.
