Definitions

  • the present invention relates generally to security devices for doors having handles, including single and double doors.
  • Dual doors are sometimes also referred to as "double doors.” Dual doors may be used in the interior of a building as well in its exterior. Exterior dual doors improve accessibility to the building and enhance the outward aesthetic appearance of the building. Interior dual doors are often used for larger passageways in non-residential buildings, and often are used to control access to or through interior spaces. Despite the benefit of convenience, dual doors present higher security risks than single doors.
  • Each of the doors in a dual door system are hinged to a respective peripheral door jamb along the outer edge of each door. Each door closes such that the respective inner edges of the doors meet at a their juncture in the middle of the doorway. Because dual doors rarely have a middle jamb member, the inner edges of the two doors must secure to each other. Some type of lock typically holds the two doors together, both to keep the doors from gliding open accidentally and to provide some measure of security.
  • the typical lock is integrated with the doors, wherein a bolt retractably extends from one door into a lock plate on the other door. The bolt has a beveled side to allow it to be forced inward when the door is closed.
  • a second retractable bolt known as a deadbolt
  • the doors can be forced open by applying enough pressure from the outside.
  • each door typically has two handles - one on each side of the door - for a total of four handles.
  • Most doors swing in one direction only, and building codes require that exterior doors swing out
  • the basic door lock comprises rounded door knobs on the interior side of the doors, and either door knobs or pull handles on the outside
  • the doors' interior side typically have exit bars and the exterior side have pull handles.
  • a security apparatus for door handles comprising two members, a first member to engage a first door handle and a second member to engage a second door handle.
  • the members each include a leg which respectively slide together to provide strength and thus resistance against the door opening.
  • the members may be connected using any of a number of attachment mechanisms, include a J-pin attached to one of the members, which permit the security apparatus to be used with a range of double door configurations.
  • the attachment mechanism is engaged in no more than one motion to firmly hold the two members together.
  • the attachment mechanism permits the two members to be detached by hand in a single movement.
  • the engagement portions include semicircular surfaces for engaging door knobs and door handles.
  • the attachment mechanism is attached to one of the two members so that it cannot be separated from the members and get lost. The attachment mechanism is easily removed to permit the members to be separated and the security apparatus easily removed in an emergency.
  • Figure 1 is a planar side view of a security apparatus for door handles in accordance with the invention.
  • Figure 2 is an elevated cutaway top view of a double door having installed thereon a security apparatus for door handles in accordance with the invention.

  • the second member 120 preferably slides into and out of the hollow in the first member 1 10 along the direction 150, and the attachment mechanism 130 is used to hold the first member 1 10 and the second member 120 together.
  • the members 110, 120 are preferably cross- sectionally round for ease of manufacturing and low cost, though other cross-sectional shapes such as square and triangular are also within the scope of the invention.
  • the first member 110, the second member 120 and the pin 133 are comprised of a strong, rigid material, such as forged aluminum, stainless steel, brass, Teflon, fiberglass or ABS. Other materials are within the scope of the invention, and may be selected if providing sufficient strength while taking into consideration their weight, cost, longevity and ease of manufacture.
  • the first member 110, the second member 120 and the pin 133 may be made of different materials, and each may themselves have components of different materials.
  • the first member 110 and the second member 120 are quite similar and may be considered analogs.
  • the first member 110 may be considered to have three functional sections — a handle engagement portion 110a, a top leg 110b and a bottom leg 1 10c.

  • the top leg 1 10b defines the holes 131a, 131b having a diameter less than the outer diameter of the top leg 110b to maintain the structural integrity of the log leg 110b.
  • the holes 131a, 131b extend through at least the top of the top leg 1 10b, near the end of the top leg 110b.
  • the top leg 110b defines the holes 131a, 131b having a diameter less than the outer diameter of the top leg 110b to maintain the structural integrity of the log leg 110b.
  • the holes 132a, 132b extend through at least the top of the top leg 120b, near the end of the top leg 120b.
  • the pin 133 comprises legs 133a, 133b and 133c.
  • the leg 133c can be variously inserted into holes 131a, 131b to provide a close fit of the 110a, 120 against the knobs 250, 260 or handles 350, 360.
  • the hole 134 is wide enough to allow the leg 133b to slide but not so large as to endanger the structural integrity of the top leg 120b.
  • the leg 133a has a length which accommodates the spacing of the holes 131 a, 132a, 131b, 132b.
  • the holes 131a, 132a, 131b, 132b need not extend completely through the respective legs 1 10b, 120b.
  • the leg 133b is preferably long enough to permit the pin 133 to be raised relative to the top leg 120b so that the leg 133c can be removed from and reinserted into the holes 131a, 131b. If the leg 133c is made shorter, then the holes 131a, 132a, 131b, 132b need not be as deep.
  • the pin 133 may be easily moved into or out of the holes 131a, 131b, 132a, 132b by hand in a single motion.

  • the first member 110 and second member 120 are preferably cylindrical and have circular cross sections. However, other cross-sectional shapes are within the scope of the invention. With respect to the legs 110b, 120b, 110c, 120c, their cross-sectional shapes are preferably complementary in those portions where they respectively engage and slide.
  • the attachment mechanism 130 functions to keep the first member 110 and second member 120 together. In early testing, the inventor found that the first member 110 and the second member 120 could be installed without an attachment mechanism and stay together. However, if force were applied to the double doors upon which the security apparatus was installed, the static friction between the first member 110 and the second member 120 was insufficient to maintain their union. The attachment mechanism 130 is therefor provided to overcome this problem. It was found that, because the first member 110 and the second member 120 effectively redirect forces applied to double doors, the attachment mechanism 130 need not be as strong as the first member 1 10 or the second member 120.
  • the various components preferably have the following dimensions:
  • FIG. 4 there is shown a planar side view of another security apparatus 400 for door handles in accordance with the invention.
  • the security apparatus 400 essentially comprises the security apparatus 100 of Figure 1 doubled-over, with two first members 110, two attachment mechanisms 130, and a central portion 450.
  • the descriptions of Figure 1 are equivalent to like representations in Figure 4.
  • FIG. 5 Another alternative embodiments of the security apparatus is shown in Figure 5.
  • the security apparatus of Figure 5 is similar to that of Figure 4.
  • the central member 450 is rod-like, and members 110 slide onto the central member 450.
  • the central member 550 is tube-like, and members 120 slide into the central member 550.
  • the members 1 10, 120 have been described as formed of tubes and rods, respectively, they may alternatively be formed if other shapes.
  • the important features are: (1 ) the engagement portions include semicircular surfaces for engaging door knobs and door handles; (2) each member includes a leg which respectively slide together to provide strength and thus resistance against the door opening; (3) the attachment mechanism is attached to one of the two members so that it cannot be separated from the members and get lost; (3) the attachment mechanism is easily removed to permit the members to be separated and the security apparatus easily removed in an emergency.
  • the engagement portions may be formed of a plate defining a semicircular region.
  • the attachment mechanism may be improved through the inclusion of a spring around the leg 133b, disposed between the flattened end 133d and the leg 120b.
  • the spring provides supplementary forces to keep the pin in the holes 131a, 132a, 131b, 132b, and this may be particularly useful if the security apparatus is installed where the pin 133 might otherwise slip out of the holes 131 a, 132a, 131b, 132b.
  • the leg 120b may be provided with a spring loaded pin or ball in the position of the hole 132a which can engage and hold the leg 1 10b at the position of the holes 131a, 131b until pressed aside by a human hand.

Abstract

Un dispositif de sécurité pour des poignées de portes comprend deux éléments. Le premier élément (110) est associé à une première poignée de porte et le deuxième élément (120) est associé à une deuxième poignée de porte. Les éléments (110, 120) comprennent chacun une partie (110b, 120b), ces mêmes parties coulissant respectivement l'une dans l'autre pour former une structure résistante qui s'oppose à l'ouverture de la porte. Les éléments peuvent être couplés au moyen d'un nombre quelconque de mécanismes de liaison (130), comprenant une cheville en forme de J (133) fixée à un des éléments qui permet d'utiliser le dispositif de sécurité dans une grande diversité de configurations de portes à deux battants. Le mécanisme de fixation (130) est en prise dans une seule configuration pour retenir solidement les deux éléments (110, 120) ensemble. Le mécanisme de fixation (130) permet de détacher les deux éléments à l'aide d'un seul mouvement de la main. Les parties de liaison comportent des surfaces semi-circulaires prévues pour bloquer des boutons et des poignées de porte. Le mécanisme de fixation (130) est fixé à un des deux éléments (110, 120) pour qu'il ne puisse être séparé des éléments et par suite perdu. Ledit mécanisme de fixation (130) peut s'enlever facilement pour permettre de séparer les éléments (110, 120) et d'enlever facilement le dispositif de sécurité en cas d'urgence.
