Door mounted door position maintaining device

Abstract

This invention is directed to a door mounted door position maintaining device with an adhesive strip for mounting on a door surface. The doorstop has a hollow body for containment of the operational parts, namely the shaft, which travels along a vertical axis and provides a way of stopping and holding the door or releasing the door from its held position. The handle used for activation or deactivation is located at one end of the shaft proximal to the top and the gripping friction foot is located at the furthest most point from the top or at the bottom. The foot uses friction when in contact with the floor to hold the door in place. A spring is utilized for additional stopping force in order to compensate for the lack of leverage due to the straight up and down orientation of the shaft. Weights may also be utilized.

Description

BACKGROUND OF INVENTION

Doorstops have long been used to hold doors in position. Oftentimes door hinges weaken, and jambs shift or sag as do building foundations. Homes and buildings often settle over time after being constructed resulting in the need for some form of device, mechanism, or object to keep doors from swinging open or closing on their own.

Prior art consists of floor or ground placed wedges, or weighted objects that must be placed or removed by bending down or using a foot to kick or manipulate placement of such stops. This can pose a problem for amputees, paraparaplegics, those with lower limb difference, persons utilizing wheelchairs or those with back issues inhibiting bending.

Other prior art must be placed within or around pinch points such ad hinge housings or tops and bottoms of doors. The placement and removal of such units can result in pinching or crushing of digits or phalanges. Floor positioned stops pose a trip and fall hazard. Other types of stops, such as wall mounted or recessed floor stops require doors to be held wide open with no allowance for partial open or closed positions.

Other prior art of the door mounted type require mounting hardware that leaves permanent holes in the door surface to which it is mounted. Such stops also require maintenance such as oiling to maintain ideal function of said stops. Such stops also lack aesthetic appeal due to their form of construction which is essential and fundamental to their function.

SUMMARY OF INVENTION

The door mounted door position maintaining device quickly mounts and adheres to door surfaces without much effort or time. It virtually eliminates the pinching or crushing hazards of digits and phalanges associated with other certain types of stops during installation.

The door mounted door position maintaining device allows for the door to be positioned at any angle from fully closed to fully open. It is very low profile thusly eliminating the trip and fall hazard associated with many other common door stop types. It's sleek low profile appearance also helps lend to its aesthetic appeal. It's design allows for ease of use for lower limb amputees, paraplegics those with back pain problems or persons with lower limb difference. It also prevents easy access to operational parts to prevent chewing and ingestion of by domestic pets.

Said means of connection being composed of metal or high tensile strength fabric or polymer or chord and being a single strand or consisting of a plurality of such strands intertwined or braided.

One iteration of the invention also possessing 113; A ratcheting or rotating and holding type mechanism, similar to that of a retractable click pen, utilizing spring(s) a roller and/or cam to both retract and retain retraction or extend and retain extension of 102; the extending appendage. 110, 112, and 120; a series of brackets for retention of 113 and guidance of 102 thereby allowing the extending appendage to raise and lower according to a predetermined path.

Mode of operation is as follows: The user adjust the body mounting height as needed to provide necessary clearance between the body and floor and extending appendage foot. The user attaches the body of the device to the door using the adhesive strip or hook and loop fastener strip. The user then connects 117; the door handle/knob grip to the door knob by stretching it over the door knob where it is held in position by friction. At this point the unit is mounted and ready for usage. Mounting of the iteration with 107; the handle, is the same with the exception of connection of 117, as there is no door handle/knob grip with the iteration possessing 107; the handle.

To initiate usage the user grasps the door knob grip and twists. As the grip twists the means of connection between the grip and extending appendage is pulled taut thereby engaging and lifting the extending appendage either directly or via engagement of the ratchet/click type mechanism. When the extending appendage is lifted the device is disengaged and the door is free to move. When the device is engaged then the extending appendage is down and in contact with the floor thereby limiting or halting door movement. The device can also be activated by turning an opposing door handle or knob on the other side of the door, which does not house the invention's door handle/knob grip but which is connected to the door handle or knob housing the invention's handle/knob grip.

In one variant iteration the door stop can also be activated via its own handle moving within a groove which guides and maintains the position of the extending appendage. The manner of mounting remains the same. In this variation activation and deactivation is achieved by lifting and sliding the units handle from either the disengaged or engaged position within 104; the gated track. It is then held in its designated position by gravity or the ratchet/click type mechanism or through tension of a spring providing force for holding power and increase of friction.
