1. Field of the Invention
The present invention relates to safety devices. More particularly the disclosed device relates to door-engageable guards for preventing injuries such as those occurring when fingers are injured between a closing door and the jamb.
2. Description of the Related Technology
It is a sad fact of modern living that most children and even adults have at some point in their life injured a finger in the jamb of a closing door. For large and heavy doors, the closing door can become an almost unstoppable swinging lever arm with immense crushing power. These accidents can be extremely painful and can break bones and can actually sever fingers.
Conventional guards are known to help prevent fingers from entering the gap between the hinged edge of the door and the door jamb. However, efforts to date to prevent the crushing of fingers positioned between the door on the latch side, and the jamb have been less than successful. Often, if in a hurry, one will close a door by simply grabbing the edge of the door and swinging it closed behind them as they pass through. This inattention to a common task greatly increases the chance of a finger getting caught between the closing door and the jamb.
Similarly, for sliding doors with no knob present, one may similarly grab the edge of the door and slide the door into the closed position with fingers directly in the path of the crushing force of the sliding door.
As such, there is a continuing unmet need for a cost effective and easily engaged device that provides protection for fingers positioned between the jamb and the latch side of closing doors. Such a device should be easily mounted and if disengageable, should preferably default to a protective position.
The device and method herein disclosed and described achieves the above-mentioned goals through the provision of a resilient member component that is adapted to absorb and dissipate the force of a door impacting the jamb when mounted to a closing door where one of two side edges of the door, is approaching a vertical face of a door jamb, sliding door frame, or another sliding door. Preferred materials include, but are not limited to, a group of compressible materials including one or a combination of polyethylene, polyurethane, polypropylene or the like. The resilient member is of desired durometer to withstand the force of a closing door. Currently a desirable durometer is between 30 a-75 d with a particularly favored range of 45 a to 55 d.
The resilient member is pivotally engaged to a base component by a rotational engagement means such as a hinge. The base component is adapted for engagement at or near a door's edge, for example by means of adhesive or screws. In one preferred embodiment, the hinge or rotational engagement means is located substantially centered on the base component. This affords the resilient member the ability to be adjusted from an as-used position where the resilient member is extended over the edge of the door at a distance greater than the thickness of a human finger, to a stored position. Preferably the resilient member is biased into the as-used position by a biasing means such as a spring, or held by a positioning means such as hook and loop fasteners. In a biased positioning the hinge or similar pivotal engagement means may be spring loaded to bias the resilient member to this as-used position, making it the default position. This is preferred since as a safety device in most instances the preferable position is to protect users. In the as-used position, as the door approaches the closed position and the resilient member is positioned proximate to the jamb, the resilient member impedes the doors edge from translating past the door jamb thereby providing a means for preventing anything in between, such as fingers, from getting crushed.
Should closure of the door be desired such as in the evening when it is to be locked, the resilient member is positionable to a stored position. Movement to the stored position is provided by a rotation of the resilient member on a hinge mechanism which allows the resilient member to rotate considerably away from the door's edge. This position allows the door to close as usual.
Should the resilient member be biased toward the as-used position, a means to hold the resilient member in the stored position may be provided such as hook and loop type fasteners or some frictional biasing means of engagement. Removal from the stored position is thereafter a simple exercise by user action of pushing upon the resilient member to disengage the hook and loop fabric (or to overcome frictional biasing) and thereby allow a rotation to the as-used position. Of course the resilient member can also be provided without the biasing toward the as-used position if desired.
With respect to the above description, before explaining at least one preferred embodiment of the herein disclosed invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangement of the components in the following description or illustrated in the drawings. The invention herein described is capable of other embodiments and of being practiced and carried out in various ways which will be obvious to those skilled in the art. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting. As such, those skilled in the art will appreciate that the conception upon which this disclosure is based may readily be utilized as a basis for designing of other structures, methods and systems for carrying out the several purposes of the present disclosed device in the protection fingers and the like from closing doors. It is important, therefore, that the claims be regarded as including such equivalent construction and methodology insofar as they do not depart from the spirit and scope of the present invention.
It is an object of this invention to provide a means to prevent fingers from being crushed in the latch side, or hinge side, of a closing door through the provision of a pliable spacing component.
It is another object of this invention to provide a means to position the resilient member from an as-used position preventing full door-closure, to a stored position allowing closure, thereby encouraging use on doors where closure might be required periodically.
It is yet another object of the current invention to encourage use by the provision of a removable means of engagement such as adhesive or a peel and stick mounting component to minimize concerns regarding marring.
It is yet another object to provide a pinch prevention device which may be employed both upon a hinged door and a sliding door, and on other closing components such as sliding drawers or cupboards to prevent pinching of fingers.
It is yet another object of the invention, to provide such a pinch protection component which also has a shock-absorption ability to help prevent door and jamb dings and potential hinge damage from slammed doors.
It is yet a further object of the invention, to provide such shock-absorption which also protects the mount of the device to the door and a stress or force disconnection thereof.
These together with other objects and advantages which become subsequently apparent reside in the details of the door pinching protection device and method herein as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part thereof, wherein like numerals refer to like parts throughout.

As seen in
The removable means of attachment employed currently is adhesive between the base component 20 and the door 30.
Currently a peel and stick two-sided tape is employed but other adhesive means may be employed. Hook and loop fabric may also be employed to hold the base component 20 to the door 30. As noted, adhesive or hook and loop are preferred as they provide a margin of “give” should the force on the resilient member 12 be sufficient to communicate along the arm 24 to the base component 20 and this provides means for slight lateral translation as a shock absorber against excessive force.
If no means for biasing is employed at the first ends of the resilient member 12, it may be held in the as-used position, or the retracted position (
In the mode of the device 10 of
Upon an impact between the resilient member 12 so mounted, force vector “A” is directed into the resilient member 12 by a compression between the vertical side edge or leading edge 29 of the door 30, and the vertical face of another sliding door or sliding door track threshold depicted as jamb 40. This force is dampened by the compression of the resilient member 12 which is formed of compressible material such as polyethylene, nylon, or polyethylene, or the like. The compression does work and dissipates some of the force before being absorbed into the door 30 by force vectors B and C as depicted. Because the force vector “A” is perpendicular to the tangent at the point of contact with the curved surface of the resilient member 12, a slight rotational force may also be imparted and absorbed by the resilient member 12.
Seen in
The tabs 23 formed by an angled inner surface of the rotational engagement 22 impart a force to maintain the arm 24 in either the as-used or stored positions. Changing between the positions require user action to rotate the support arm 24 from one position to the other, and past a tipping point in the tabs 23 which is the narrowest separation between the two rotational engagements. Once past this tipping point, the support arm 24 is continually biased to stay in its respective position.
Another mode of biased rotational engagement is shown as base component 20, rotational engagement 22, and support arm 24 is seen in
An additional mode of the resilient member 12 is seen in

The force from the rotation upon the engagement of the support arm 24 is dampened by the translation of the ends of the support arm 24 along the slot 31.
