DETAILED DESCRIPTION

[0016] With reference to the drawing figures, this section describes particular embodiments and their detailed construction and operation. Throughout the specification, reference to “one embodiment,” “an embodiment,” or “some embodiments” means that a particular described feature, structure, or characteristic may be included in at least one embodiment. Thus, appearances of the phrases “in one embodiment,” “in an embodiment,” or “in some embodiments” in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the described features, structures, and characteristics may be combined in any suitable manner in one or more embodiments. In view of the disclosure herein, those skilled in the art will recognize that the various embodiments can be practiced without one or more of the specific details or with other methods, components, materials, or the like. In some instances, well-known structures, materials, or operations are not shown or not described in detail to avoid obscuring aspects of the embodiments.

[0017] Referring first to FIG. 1, therein is shown a device 10 according to one embodiment of the present invention. The device 10, includes an elongated strap 12 which may be made of a high-strength webbing material, for example one-inch in width. At a first end of the strap 12 is an attachment means 14 which is used to secure the first end 16 of the strap 12 to one of the pivot-hinged arms of a door-closer device. The attachment means 14 may comprise, for example, mating hook-and-loop material surfaces that allow the first end 16 to be wrapped and fastened to a door-closer arm. FIG. 1A shows an alternate attachment means in the form of a ring 15 secured to the first end 16 such as by sewing. The first end 14 is secured to the arm buy looping the strap 12 around the arm and passing a second end 18 and remainder of the strap 12 through the ring 15. Other means of attachment, whether a snap or more permanent fastening, like a rivet, may be used as well. The second end 18 of the strap 12 may include a handle portion 20 to facilitate gripping with a hand. The handle 20 may be an extended end portion of the strap 12, a folded portion to add stiffness, or a loop. The handle 20 may be a contrasting and/or bright color to allow easy recognition. The strap 12 may be from 12 inches to 36 inches in length, for example.

[0018] According to the illustrated embodiment, substantially the entire length of one side of the strap 12 may be covered with hook-type fastener material 22 and the opposite side 24 covered with loop-type fastener material. If desired, the fastener material can be attached, such as by sewing or with an adhesive, in segments to facilitate folding of the strap 12. Alternatively, the strap may be made of a material that has mating hook-and-loop materials integrated into opposite sides thereof.

[0019] Referring now to FIG. 2, therein is shown the first end 16 of the strap 12 secured to one of the closer arms 26, 28 distal from the pivot connection 30 (not shown in FIG. 2).

[0020] Referring now to FIG. 3, therein is shown how the strap 12 of the device 10 may be folded while the first end 16 is attached to a closer arm 26 and ready to be deployed for use. The strap 12 may be held in the folded condition by an elastic or breakable band 32. Simply pulling downward on the handle 20 will cause the band 32 to dislocate or break, extending the strap 12 to its full length. By being folded, it extends rapidly and does not require unrolling or other preparation for use.

[0021] Referring now to FIG. 4, in order to secure the door against opening, the closer arms 26, 28 may be bound together by wrapping the strap 12 around the arms 26, 28 multiple times. By having mating hook-and loop-type fastener materials 22, 24 on opposite sides of the strap 12, the overlapping layers of the wound strap 12 adhere to each other with extraordinary tensile and sheer strength, and with virtually no stretch.

[0022] Referring now to FIG. 5, the device 10 is shown in a fully operational condition in which the closer arms 26, 28 are bound together distal to the pivot joint 30. By preventing the closer arms 26, 28 from moving apart, the door is secured against opening from the opposite side. Securing the strap 12 on the arms 26, 28 distal from the pivot joint 30, the leverage of moving the door in minimized and allows the door to be opened only a negligible amount.

[0023] While one or more embodiments of the present invention have been described in detail, it should be apparent that modifications and variations thereto are possible, all of which fall within the true spirit and scope of the invention. Therefore, the foregoing is intended only to be illustrative of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not intended to limit the invention to the exact construction and operation shown and described. Accordingly, all suitable modifications and equivalents may be included and considered to fall within the scope of the invention, defined by the following claim or claims.
