8 Claims, 4 Drawing Figures SHOCK ABSORBING RAIL ASSEMBLY BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to protective rails and hand rails and more particularly, to rails adapted to extend horizontally in spaced relation to walls to be protected and including a flexible resilient material constituting a portion thereof and forming a contact surface to absorb the impact of articles inadvertently moved thereagainst.
2. Brief Description of the Prior Art Various types of chair rails, hand rails, protective bumper elements and similar devices have heretofore been provided to protect walls and other surfaces from damage resulting from contact therewith of chairs, portable carts and other types of articles, and to provide a support which may be gripped with the hand for stability and aid in walking. Generally, such chair rail and protective bumper elements have been designed primarily to provide the protective function sought, and shield the wall from impact with articles of the type described. Secondarily, these devices have been designed to be aesthetic in appearance, since they are generally mounted in an exposed location within a room or hallway. Chair rail assemblies of the general type described are disclosed in my co-pending US. patent application Ser. No. 179,277, now US. Pat. No. 3,775,926 filed Sept. 10, 1971 and entitled Shock Absorbing Chair Rail Assembly.
Various structures have been provided for mounting such chair rails, hand rails, or protective bumper elements to a wall, and in general, function to space the impact absorbing surface, and a rail upon which it is mounted, horizontally from the wall in a cantilevered fashion. With this type of mounting arrangement, it is important that the mounting structure be sturdy and retain the chair rail or other protective, impact absorbing structure in a stationary position where damage is not sustained by such structure as a result of heavy impact forces delivered to any portion thereof.
BRIEF DESCRIPTION OF THE PRESENT INVENTION The present invention proposes an improved combination shock absorbing chair rail assembly or hand rail assembly which can be quickly and easily mounted to a wall or other vertical surface by means of a plurality of brackets. The rail assembly, when mounted to a wall, is sturdy and able to withstand high impact forces without damage. Moreover, the manner in which the wall mounting brackets are attached to the elongated rail facilitates and expedites installation.
Broadly described, the present invention comprises an elongated, rigid supporting member or rail having at least one bumper strip receiving channel extending over the length thereof. A flexible and resilient bumper strip is mounted in the channel. The rigid supporting member is mounted to a wall in spaced relation thereto by a plurality of mounting brackets. Each of the mounting brackets includes a base portion adapted for securement to the wall by suitable fasteners, a mounting portion secured to the elongated supporting member or rail, and a web portion interconnecting'the base portion and the mounting portion.
The mounting portion of each mounting bracket is secured to the elongated, rigid supporting member or rail by means of bolts extended through a flange fonning part of the mounting portion, and through a slot formed in one side of the rail and communicating with a channel defined by the rail. A nut slidably mounted in the channel threadedly engages the bolt. Engagement of the mounting bracket with the supporting member or rail is also effected by means of registering or interlocking tongue-and-groove type surfaces.
An important object of the invention is to provide a shock absorbing rail assembly which functions effectively to protect a wall from damage resulting from chairs, mobile carts or other objects striking the wall.
Another object of the invention is to provide a hand rail or shock absorbing rail assembly which can be quickly and easily mounted to a wall in cantilevered fashion without the use of complicated tools.
Afurther object of the invention is to provide a protective rail structure which can be mounted to substantially any wall in an expeditious fashion, and can be quickly and easily demounted from the wall.
Yet another object of the invention is to provide a mechanically strong shock absorbing rail assembly which, in use, is cantilevered from the wall, yet is stable and able to withstand severe impacts without damage.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION Referring initially to FIG. 1 of the drawings, shown therein is a rail assembly constructed in accordance with the present invention. The assembly includes an elongated, rigid supporting member or rail 10 which, in the illustrated embodiment, is a metal extrusion. As depicted in FIG. 2, the elongated rigid supporting member'10 includes a front wall 12, a back wall 14, a top wall 16 and a bottom wall 18. The front wall 12 is configured to define a pair of elongated channels 20 and 22. Each of the channels 20 and 22 has undercut lips 24 and 26, and each of the channels receives an elongated bumper strip 28 which is constructed of a flexible, resilient material, such as rubber or synthetic resin. Each of the bumper strips 28 defines a space between the bumper strip and the portion of the front wall 12 which defines the bumper strip channel 20 or 22. This void or air space functions in conjunction with the bumper strip 28 to absorb impact forces delivered to the shock absorbing rail assembly upon impact therewith by a chair or other object moved against the rail assembly.
The back wall 14 of the elongated, rigid supporting member or rail is slotted or grooved about midway of its transverse dimension, as indicated by reference numeral 30, to provide an elongated groove of V- shaped cross section which extends over the length of the elongated rigid supporting member. At the intersection of the back wall 14 with the lower wall 18 of the elongated supporting member 10, a slot 32 is formed along the length of the rigid supporting member 10 and functions to receive the shank of fastening bolts 34 for a purpose hereinafter described. The slot 32 opens into an elongated channel 36 which extends the entire length of the rigid supporting member 10 and is completely enclosed except for the opening thereinto of the slot 32. A pair of terminal caps 38 are secured to the elongated, rigid supporting member 10 at its opposite ends.
A second major subassembly of the rail assembly 10 is a mounting bracket designated generally by reference numeral 40. In general usage, a plurality of the mounting brackets 40 will be employed for supporting the elongated, rigid supporting member 10 in spaced relation to a wall 42 in the manner depicted in FIG. 2. The mounting bracket 40 in the embodiment of the invention illustrated in FIGS. 1 and 2 is a generally U- shaped member which includes a base portion 44 having a bolt hole or bolt aperture formed therethrough for the purpose of receiving the shank of a bolt 46 or other suitable fastening member. Extending from the base portion 44 in parallel relation to each other are a pair of legs or webs 48 and 50. The upper leg 48 is provided at its free outer end with a generally triangularly shaped tongue portion 52 which is configured to register with and engage the groove 30 formed in the back wall 14 of the elongated, rigid supporting member 10. The mounting bracket 40 further includes a flange 54 which projects downwardly from the leg or web 50 and is apertured to accommodate the shank of the bolt 32. The threaded end of the bolt shank engages a hexagonally shaped nut 56 which is slidably received in the channel 36. The channel 36 is dimensioned to slidably receive a plurality of the nuts 56, but the hexagonally shaped nuts cannot rotate in the channel. The open ends of the channel 36 are closed by the terminal caps 38 when these caps are secured to opposite ends of the rail 10.
In mounting the shock absorbing or hand rail assembly to a wall, a plurality of the mounting brackets 40 are first bolted to the wall by means of bolts 46 which are extended through the base portions 44 of the mounting brackets and into the wall upon which the assembly is to be supported. The elongated rigid supporting member 10 is then fitted to the several mounting brackets by engaging the tongue portion 52 with the groove 30. When such engagement has been effected, the lower portion of the back wall 14 of the rigid supporting member 10 rests flatly against the flange 54, and the bolts 34 may be extended through the bolt openings or apertures which are provided through these flanges. Prior to the extension of the bolts through the openings in the flanges 54 of the mounting brackets 40, however, the requisite number of nuts 56 are slid longitudinally within the channel 36 until alignment of the nuts with the apertures through the flanges 54 is achieved. In this way, the threaded portion of the shan ks of the bolts 34 may be threaded into the nuts 56, and the lower portion of the elongated rigid supporting member 10 can be drawin tightly against the flanges 54 of the brackets 40.
With the described mounting arrangement, the elongated rigid supporting member 10 is held securely in position in horizontally spaced relation to the wall 42. The protective bumper strips 28 are exposed and project outwardly in a position to receive and absorb impact forces delivered by chairs or other objects which may be inadvertently moved against the shock absorbing rail assembly. The interlocking fit between the mounting brackets 40 and the elongated rigid supporting member or rail 10 is such that the supporting member can be quickly and easily detached from the brackets if it should be desired to remove the shock absorbing rail assembly from the wall. Moreover, the provision of the channel 36 and slot 32 in the lower portion of the elongated rigid supporting member 10 makes the shock absorbing rail assembly quickly and easily mountable in substantially any location, ragardless of where it is necessary to place the mounting brackets 40 on the wall.
A second or alternate embodiment of the invention is depicted in FIG. 4 of the drawings. In this embodiment of the invention, an elongated, rigid supporting member or rail is designated generally by reference numeral 60. The rigid supporting member 60 is a hollow structure which includes a front wall 62, a back wall 64, a top wall 66 and a bottom wall 68. Formed in the front wall 62 is a bumper strip channel 70 configured similarly to the bumper strip channels 20 and 22 of the embodiment of the invention hereinbefore described. The bumper strip channel 70 is defined in part by a pair of undercut toe portions 72 and 74 formed integrally with the front wall 62. A flexible and resilient bumper strip 76 formed of a flexible or resilient material is mounted in the bumper strip channel 70 in the manner illus trated, and performs a shock absorbing function as hereinbefore described.
Formed through the bottom wall 68 of the elongated, rigid supporting member 60 is an elongated, longitudinally extending slot 80 which extends over the length of the rigid supporting member 60 and opens into a channel 82 formed above the bottom wall 68. The channel 82 is completely enclosed except for the opening thereinto of the slot 80 and slidably receives a plurality of threaded nuts 84. A groove 86 is formed in the bottom surface of the bottom wall 68 for the accommodation of a tongue portion of a mounting bracket as hereinafter described.
The elongated, rigid supporting member 60 is supported in horizontally spaced relation to a wall 90 by means of a plurality of mounting brackets designated generally by reference numeral 92. Each of the mounting brackets 92 includes a base portion 94 having formed therethrough, a screw receiving aperture or opening to permit a screw 96 or other suitable fastening member to be extended through the base portion 94 into the wall 90. Projecting outwardly from the base portion 94 in a direction substantially normal thereto is a web portion 98. At its outer end, the web portion 98 carries a flange 100 which has a bolt opening or aperture formed therethrough to accommodate the shank of a bolt 102. The threaded end of the shank or bolt 102 is engaged with one of the nuts 84. It will be noted in referring to FIG. 4 that the flange 100 of the mounting bracket 92 is configured and dimensioned so as to mate with, and engage, the groove 86 formed in the lower surface of the bottom wall 68 of the elongated rigid supporting member 60.
In the use of the shock absorbing rail assembly embodiment of the invention which is depicted in FIGS. 3 and 4, the mounting brackets 92 are first secured to the wall by means of the screws 96 or other fastening means. The elongated, rigid supporting member 60 is then secured in position on the mounting brackets with the groove 86 engaging the complimentary shaped flange 100 forming a portion of each of the mounting brackets. The nuts 84 are slid longitudinally in the channel 82 until they are aligned with the bolt apertures formed through the flanges 100 in the several mounting brackets 92 which are utilized. Bolts 102 may then be engaged with the nuts 84 in the manner depicted in FIG. 4 to firmly secure the elongated, rigid supporting member 60 in position on the mounting brackets.
From the foregoing description of the invention, it will be perceived that the present invention provides a mechanically sturdy, easily installed rail assembly which functions equally well for both shock absorption and hand rail purposes. Although certain preferred embodiments of the invention have been herein illustrated in order to explain and define the basic principles upon which the invention is based, it will be understood that various changes and innovations can be effected in the illustrated and described structure without departure from such basic principles.
