NL8303162A - Door hinge finger guard - comprises one-piece strip of constant thickness and cross=section - Google Patents

Abstract

The door or window guard strip prevents fingers being trapped in the hinge on shutting. Each strip is preferably in one piece, of constant thickness and cross-section. It can comprise stiff and flexible parts extending parallel to each other in the lengthwise direction. The flexible parts are designed so that from the extended position they can fold to an acute angle in one direction only, preventing the strip penetrating into the hinge opening.

Finger protection strips for doors and windows on the hinge side.

The invention relates to protective strips to be used in hinged door and window constructions, to protect against fingers becoming trapped on the hinge side of the door or window, in the closing movement of the door panel or window. Especially with doors, there is a dangerous zone on the hinge side, because the space between the door and the frame created by the opened door often makes it possible to intervene here with the fingers or with part of the hand. If the door is closed in this situation, there is a risk of injury to the fingers or hand, because the lever action is considerable and the more so because the thicker finger joint is likely to get caught between the door edge and the usually present stop or stop bar. touch. Retraction of the fingers is then difficult to impossible. The combination of occurring tensile and shear loads can lead to serious injury or loss of the fingers.

The object of the invention is to eliminate the mentioned possible risk of injury with existing and new door and window constructions. This object is achieved by shielding said danger zones with preferably one-piece finger protection strips, which in the basic form have an even thickness and a constant cross-section, while the length of the strips is at least the part of the height of the door that is within reach of children. covers, or covers this entire height for aesthetic reasons and to utilize the additional draft-resistant property. According to the invention, the strips consist partly of rigid, partly of flexible areas which are situated parallel in the longitudinal direction of the strips 25, the flexible areas being able to reach the sharply folded state in one direction from the stretched state in one direction only. which prevents the strip from bending in the opposite direction from being pressed into the above-mentioned danger zone, so that the fingers cannot get into it either.

In this way, finger protection strips are obtained, which in a practical embodiment of the invention are preferably provided with rigid longitudinal edge strips, with which the strips are simply joined on both sides by gluing, stapling, nailing, screwing or otherwise of sufficient adhesion. from the dangerous hinge opening.

From the "Publication" 8003123 of German origin, a functionally comparable construction is known with this invention, wherein the

* - 2 - finger protection in the area of the door hinge on the hinge side is achieved by using a rib-shaped profile with circular arc-shaped cross section. This profile, with sealing elements against dust and draft, is attached to the specially designed door panel 5 and is stored when the door is closed in the hollow frame, which is also specially designed for this purpose. However, in comparison with the invention, the German construction is more complicated and the limitations that the door opening cannot be greater than 90 °, that the pivot axis must be very close to the outer surfaces of the door panel and the frame, that the construction 10 cannot be used. fit with swing doors and that the construction cannot simply be added to existing situations.

The invention will be elucidated with reference to drawings in which some exemplary embodiments are presented.

Fig. 1 shows the basic cross section of a finger protection strip. The central area 1 serves to shield the danger zone, the edge strips 2 and 3 serve to fix the strip. The arcuate arrows indicate the only possible bending direction. The flexible areas are in the center of the arrow arcs and are shown in arbitrary number and design for example.

Fig. 2 shows the strip shown in Fig. 1 in use. The door panel 4 pivots about the pivot axis 5 to approximately 100 ° opening relative to the frame 6. The strip attached at 7 and 8 is brought from the closed position 9 to the open position 10. The danger zone 11, as seen from the stop side of the door, is covered throughout the entire trajectory of the strip. It should also be noted that when the door is closed, apparently new danger zones arise at 12 and 13. These do not pose any danger to the fingers when the material is chosen and the strip is constructed, because the triangular area 14 is easily deformed.

Fig. 3 shows a variant of the strip shown in Fig. 1, in which the dimensions and the location of the flexible areas are chosen such that a door opening of up to 180 ° is possible.

Fig. 4 shows a variant of the strip shown in Fig. 1, applied here on the pivot axis side of the door, in those cases where the pivot axis is located so far outside the surfaces of the door and the frame that a Danger zone 15 exists, which is covered up to 180 ° door opening from the axis of rotation of the door in the entire travel path.

Fig. 5 shows a variant of the strip shown in Fig. 1, used here with a swing-through hinge construction, such as in use with swing doors.

Claims (6)

1. Finger protection strips for doors and windows on the hinge side, to protect against fingers getting trapped by the closing movement of the door panel or window, characterized in that the strips are preferably one-piece and have an even thickness in the basic form 5 and have a constant cross section. Finger protection strips according to claim 1, characterized in that the strips consist of partly rigid, partly flexible regions, which lie parallel in the longitudinal direction of the strips, the flexible regions from the stretched condition only in one direction up to 10 in. sharply folded condition can be achieved in that direction, thereby preventing the strip from being able to bend in the opposite direction in the danger-opening hinge opening. Finger protection strips according to claims 1 and 2, characterized in that the strips are provided in the longitudinal direction with rigid edge strips, with which the strips can be applied on both sides of the hinge opening by gluing, stapling, nailing or screwing, with which the strips in various designs can be installed by the user himself, in addition and without intervention on existing and new hinge, cover hinge and knock-through hinge constructions, whereby the 20 potentially hazardous hinge openings can be covered adequately, over the entire route from 180 ° opening to the closed situation. Finger protection strips according to claims 1, 2 and 3, characterized in that the length of the strips covers at least the part of the height of the door or window, which is within easy reach of 25 children, or the entire height in order to prevent the draft-resistant property of the to use strips, so that a draft strip on the present hinge side of the door or window is superfluous, so also to allow an imprint of, for example: a graduation in centimeters up to two meters, so also for aesthetic reasons in which the possible diversity of colors applies. Finger protection strips according to claims 1, 2, 3 and 4, characterized in that the strips are preferably manufactured by a thermoplastic process such as extrusion, from a plastic usable for the intended purpose, such as polypropylene, or from a composition of various others materials, depending on the chosen embodiment of the unidirectional flexible regions, as mentioned in claim 2 and in Pig. 1 is presented for example, in any possible effective material thickness. 8.
