The present applications is related to pending U.S. application no. 29/268,719 filed Nov. 8, 2006 for Security Bar Brackets design.
The present invention is directed to security bar brackets for patio doors, basement windows, and sliding windows and the like.
Locks and security devices for sliding doors and window assemblies have taken many formats from locking pins, locking levers, door/window bars, and brackets.
Key plug locks, locking pins and locking levers have an obvious drawback in a panic or emergency situation such as with a hot fire or heavy smoke. These devices take concentration to operate and are not panic friendly.
Brackets and bars have become very popular because the strength of the locking function offered. These security bars and brackets have been offered in generally one of two types of confirmations. The first confirmation is a pair of upward-facing U-shaped type brackets, one mounted to each juxtaposed face of each door/window jamb to be inhibited from operating. The brackets are generally mounted in the middle of the door, i.e., at about mid-height. This confirmation presents two shortcomings. The first is that it is not “jimmy proof” from a jimmy tool inserted between the door/window seals and lifted upward. The second is that it requires the presence of mind by the occupant of the building, in a panic situation, to lift the bar upward to remove the bar and permit the door/window to be opened.
An alternate to the upward-facing U-brackets is to drop the security bar into the slider channel for the doors/windows. This provides a considerably more jimmy proof use, but creates a more dangerous lock in a panic situation, as the bar generally must be pried, by a flat object, out of the slider channel, in order to release the door/window to open. This is a much more dangerous situation in the presence of a fire, a gas leak emergency, or other panic situation.
The second confirmation offered has the bar secured to one door/window juxtaposed jamb, generally the middle, by a pinned pivot bracket. An upward-facing U-type bracket is mounted to the facing jamb to receive the free end of the security bar. The pinned pivot bracket end of the bar dissuades jimmying. However, the pinned pivot bracket presents an awkward release movement, especially in a panic situation.
What is desired is a security bar and brackets which hole the security bar in a relatively jimmy proof manner but which release the bar easily in a panic situation.
An objective of the present invention is to provide such desired security bar brackets to be easily mounted to juxtaposed patio door jambs or sliding window jambs in a proper orientation for optimum operation.
The objectives of the prevent invention are realized in a pair of brackets, of mirrored structure, which can be attached, one each, to juxtaposed sliding patio door or sliding window section jambs for holding a security bar there between, which held bar prevents said door or window from opening until removed by user from inside.
Security bar and brackets are fitted to the particular size of the sliding patio door or sliding window, wherein the brackets are mounted in a juxtaposed position on the face of the door or window section jamb, for holding and releasing the security bar.
A socket structure on each bracket holds the end of the security bar. Walls on each bracket define a slot in which the security bar ends move and guide the bar ends to the seated or removed positions.
Alignment surfaces make for ease of installation and concurrent alignment of the pair of brackets. Counter-sunk screw holes or other attachments are used in mounting each bracket to its respective jamb.
The slot in each bracket guides the security bar into and out of the brackets. The movement of the security bar is in-and-downward when being inserted and upward-and-outward toward the operator when being removed. The path of movement dissuades jimmying.
The brackets permit an “angled” or “arc-path” drop-in and pull-out operation of the security bar which presents a jimmy resistant structure, but one which is easily operable to release the security bar, in a panic situation.
The features, advantage and operation of the present invention will become readily apparent and further understood from a reading of the following detailed description with the accompanying drawings, in which like numerals refer to like elements, and in which:
The present invention is a security bar assembly for a sliding patio door and/or a sliding window. This security bar assembly includes a pair of brackets that are mountable, in juxtaposed position, on facing door or window section jambs. Usually the brackets 11, 13,
The brackets 11, 13 permit the installation of the security bar 23, by pushing it into the bracket openings and allowing it to drop down into the brackets 11, 13. Removal of the bar 23 is affected by pulling up and towards the operator. This is a natural motion in a panic situation.
The security bar 23 can be of any cross-sectional shape. However, a round bar or post is convenient. The security bar 23 can be made of any material, from a metal pipe, to a wooden bar, post or dowel, to a plastic or fiberglass post. The size of the bar 23 and the size of the brackets 11, 13 are chosen to be compatible to the sliding patio door and/or sliding window application. The bar 23 can be cut to length. With the bar 23 manually removed,
The security bar 23 brackets 11, 13 are shown in detail in
The curved walls 37, 37′ each form a respective socket area 39, 41 on the respective brackets 11, 13. Each wall 37, 37′ has a top portion, a rounded return portion and a bottom portion. The rounded return portion forms the bottom of a socket 39, 41 in which an end of the security bar 23 rests.
Each socket 39, 41 area provides an entrance opening wide enough to receive the bar 23 end. The top portion of a wall 37, 37′ has a curved section 43 where the socket area 39, 41 curves downward. This concave curved section 43 and the remainder of the top portion of a wall 37, 37′ forms a guide which controls the insertion and removal motions for a security bar 23.
When inserting a security bar 23, the ends thereof ride in each socket area 39, 41. As the bar 23 is inserted into each bracket with a horizontal motion, it is forced downward into the bottom of the socket area 39, 41 to rest on the rounded bottom portion.
When removing a security bar 23, it is pulled up and towards the operator and its travel motion within a bracket 11, 13 is guided by the walls 37, 37′.
If a burglar attempted to jimmy the security bar, he would have to lift the bar 23 which would then hang up on the top portion of the walls 37, 37′ and specifically the curved portion 43. This would then require the burglar to move the bar 23 into the room, which is a motion not presently capable with known jimmy tools.
Each back wall 29, 29′ has a pair of counter-sunk fastener holes 45, 47 for mounting the respective bracket to the inside of the sliding patio door sliding section and the edge of the door frame on the non-sliding section.
The insertion path of travel of a security bar into the brackets is first horizontally inward and then downward at about a 45 degree angle. The removal path of travel is upward at about a 45 degree angle and then outward horizontally.
Many changes can be made in the above-described invention without departing from the intent and scope thereof. It is therefore intended that the above description be read in the illustrative sense and not in the limiting sense. Substitutions and changes can be made while still being within the scope and intent of the invention and of the appended claims.
