Hand brake locking system

Abstract

A rail car hand brake locking system utilizes a connection member and a securing body. The connection member has an aperture near each distal end. The securing body has a head end capable of securing around a portion of an actuating wheel of the hand brake and a connection end capable of securing to the connection member, which is then affixed to the hand brake housing. The system prevents unauthorized usage of the hand brake.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(12) The best mode for carrying out the invention is presented in terms of its preferred embodiment, herein depicted within FIGS. 1 through 9. However, the invention is not limited to the described embodiment, and a person skilled in the art will appreciate that many other embodiments of the invention are possible without deviating from the basic concept of the invention and that any such work around will also fall under scope of this invention. It is envisioned that other styles and configurations of the present invention can be easily incorporated into the teachings of the present invention, and only one (1) particular configuration shall be shown and described for purposes of clarity and disclosure and not by way of limitation of scope.

(13) The terms a and an herein do not denote a limitation of quantity, but rather denote the presence of at least one (1) of the referenced items.

(14) The present invention is directed to a hand brake locking system (herein described as the system) 10, particularly suited for rail cars.

(15) Referring now to the drawings, there is shown in FIG. 1 a system 10 during an in-use condition, showing the securing body 20 and connection member 30 secured and locked to an actuation wheel 40 of a hand brake 60, according to an embodiment of the present invention.

(16) A preferred embodiment of the system 10 comprises a securing body 20 and a connection member 10. The securing body 20 may comprise a head end 22, an extension portion 28, 29, and a connection end 26. The head end 22 may comprise a wrench-head extending from the securing body shaft 24. The connection end 26 is opposite the head end 22 and may be manufactured with a securing body aperture 25. The head end 22 may virtually take on a similar shape to that of a conventional one-sided open ended wrench. The purpose of the head end 22 and an extension portion 28, 29 provided by the securing body 20 may be to prevent an unauthorized user from turning the actuation wheel 40 of a rail car hand brake 60, as shown The head end 22 engages a portion of the nut on the actuation wheel 40 and cannot be slid off.

(17) The extension portion 28, 29 may be structured and arranged such that it may extend away from a side of the securing body shaft 24. The extension portion 28, 29 may structurally embody a relatively L-shaped member, having an extension first member 28 extending away from a first side of the securing body shaft 24, at a minimal angle from perpendicular, and an extension second member 29 extending generally perpendicular from the extension first member 28 and rearwardly relative to the securing body shaft 24. This shape is configured as such in order to provide clearance of the extension member 28, 29 around a corner of the rail car hand brake housing 60. As shown, the extension portion 28, 29 may abut on top of a release arm 61 of a rail car hand brake 60 to add stability to the system 10 when in-use and restrain upward movement of the release arm 61. The securing body shaft 24 may act as a unitary rigid unit in order to prevent malfunction of the system 10 when properly attached to a rail car hand brake 60.

(18) The connection member 30 may comprise a separate component structured and arranged in a relatively L-shaped member, comprising a connection member first end 31 and a connection member second end 32. A connection member first aperture 33 is located adjacent a distal end of the connection member first end 31 and similarly, a connection member second aperture 34 is located adjacent a distal end of the connection member second end 32. The connection member second aperture 34 may be of a design to allow a fastener, such as a bolt, to mount the connection member 30 to a top section of the rail car hand brake 60. Alternatively, the connection member 30 may be welded to a rail car hand brake 60. Other fastening means may be used.

(19) The connection member first aperture 33 and the securing body aperture 25 may be of adequate size to allow a shackle of a lock 50 to penetrate therethrough when the connection member 30 and securing member 20 are placed adjacent to each other. The connection member 30 may be fixedly attached to a rail car hand brake 60, and may provide a secure connection between the securing body 20 and rail car hand brake 60.

(20) In other embodiments of the system 10 the connection member 30 may not be provided, and may instead be obtained separately. The exact specifications, materials used, and method of use of the system 10 may vary upon manufacturing.

(21) The foregoing descriptions of specific embodiments of the present invention have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention and method of use to the precise forms disclosed. Obviously many modifications and variations are possible in light of the above teaching. The embodiment was chosen and described in order to best explain the principles of the invention and its practical application, and to thereby enable others skilled in the art to best utilize the invention and various embodiments with various modifications as are suited to the particular use contemplated. It is understood that various omissions or substitutions of equivalents are contemplated as circumstance may suggest or render expedient, but is intended to cover the application or implementation without departing from the spirit or scope of the claims of the present invention.
