Abstract

A wall or room partition mountable modular rail rack component mounting system. The system includes wall racks shaped for interlocking engagement with each other at their opposite ends and cross stiffener members for placement between the wall rails to hold them in rigid space apart relationship. The wall rails each having a shaped opening at one end and a mating element at the other end thereof. The shaped opening and the mating element interlock with each other. The dimensions and spacings of openings and elements on the wall rails and rail racks for mounting thereon provide for rail racks mounted in vertically aligned closely space relationship that gives uninterrupted rail rack placement.

Claims

1. A wall mountable modular component mounting system comprising:

wall rails each made of rigid material having a thickness dimension "t" and configured for interlocking engagement with each other at opposite ends, each rail comprising an elongated central portion and an upstanding wall portion at each of the longitudinal edges of such elongated central portion, the upstanding wall portions extending away from the elongated central portion on the same side of the rail to maintain such central portion in spaced apart relationship with a wall on which the system is mounted, the central portion having opposing elongated major surfaces, the elongated major surface on the side of the rail opposite the upstanding wall portions being outwardly facing surface when the system is mounted on a wall and the other major surface being inwardly wall facing surface, the outwardly facing surface including a main surface portion, an end surface portion narrower in width than the main surface portion, and a transition surface portion, the end surface portion terminating one end of the rail, such end surface portion being parallel to and laterally offset from the main surface portion a distance substantially equal to the thickness dimension "t" in a direction placing the main surface portion further from a wall than the end surface portion when the system is mounted on a wall, the adjacent ends of the end surface portion and of the main surface portion being connected by the transition surface portion, such transition portion extending in inclined relationship with the main and end surface portions, the rail having a hanging/mounting opening through the rigid material at the end of the rail having the end surface portion, such opening being shaped to include a central space with a width dimension "w" and a generally rectangular hanging slot aligned with a mounting slot, the central space extending lengthwise of the rail in the end surface portion and across the transition surface portion, each of the aligned slots being defined by two generally parallel side edges separated by a distance "d" that is smaller in dimension than the width dimension "w" of the central space and an end edge, the aligned slots being in communication with the central space on opposite sides thereof and extending lengthwise of the elongated central portion with the mounting slot being located entirely in the main surface portion and the hanging slot being located entirely in the end surface portion, a pair of wings of rigid material having a thickness dimension "t" located at the other end of the rail, the wings being mounted on the rail in spaced apart parallel relationship with the inwardly wall facing surface to define two generally parallel channels extending lengthwise of the elongated central portion, the channels each having a height dimension "h" greater than the thickness dimension "t" and the wings having a span dimension "s" greater than the distance dimension "d", the end surface portion of each of the rails being sufficiently narrower in width than the width of the other end of each of the rails to allow the inwardly wall facing surface at the other end of a first rail to be placed in contact and in an interlocking position with the end surface portion of a second rail with the upstanding wall portions of the other end of the first rail having its wings located in an immediately outside adjacent relationship with the upstanding wall portions of the end surface portion of the second rail, the wing extending through the central opening of the second rail to the inwardly wall facing surface side of the first rail for movement of the rails relative to each other to establish an interlocking .relationship between the wings of the first rail and rigid material of the second rail defining the hanging slot.

2. The wall mountable modular component mounting system of claim 1 wherein the hanging slot and the mounting slot are different lengths.

3. The wall mountable modular component mounting system of claim 2 wherein the central space of the hanging/mounting opening is defined by slant edges at each of its of its corner regions.

4. The wall mountable modular component mounting system of claim 1 wherein the central space of the hanging/mounting opening is on the longitudinal axis of the rail.

5. The wall mountable modular component mounting system of claim 1 further including:

a mounting bracket at the other end of each of the rails, such bracket laterally extending from the rail and having formed thereon a pair of wings of rigid material having a thickness dimension "t", the wings being mounted in spaced apart parallel relationship with the inwardly facing surface of the bracket; and

a cross stiffener member including a longitudinal main portion and a lower channel portion comprising a lip and a bottom, the main portion having an opening at each end that includes a slot extending transverse of the main portion and an entrance slot in the bottom that is in communication with the slot in the main portion, the entrance slot being so dimensioned as to allow the wing on the mounting bracket to move therethrough and move into the slot in the main member, the span "s" of the wings is greater than the width of the slot in the main member so as to establish an interlocking relationship between the wings and rigid material of the rail at the edges of the rail defining the slot in the main member.

6. The wall mountable modular component mounting system of claim 1 further including a rail rack and wherein the main surface portion of each of the wall rails has a rack mounting opening in spaced apart relationship with the hanging/mounting opening, the rack mounting opening including a generally rectangular rack mounting slot in communication with a larger rack mounting space, the rack mounting slot being defined by parallel side edges separated by a distance "d" and an end edge, the rack mounting slot extending lengthwise of the main surface portion and aligned with the mounting slot of the hanging/mounting opening, the rail rack including a generally rectangular back member and side member, the back member having formed at each end thereon a pair of wings of rigid material having a thickness dimension "t", the wings of the back member being mounted in spaced apart parallel relationship with the inward wall facing surface of the back member when the system is mounted on a wall, the distance between the wings of the rail rack being equal to the distance on each wall rail between the hanging/mounting opening and rack mounting opening, the wings of the back member having a span "s" that is greater than the width of the rack mounting slot and the wall rail mounting slot so that when the wings of the back member and a wall rail are positioned with respect to each other with one of the wings of the back member extending through the central space of the hanging/mounting opening and the other of the wings of the back member extending through the larger rack mounting space of the rack mounting opening of the rail rack and a wall rail can move relative to each other to mount the rail rack on the wall rail by establishing an interlocking relationship between the wings of the back member and the slots of the wall rail.

7. The wall mountable modular component mounting system of claim 6 further including a second rail rack identical to the rail rack and wherein on each wall rail the location of the end edge of the mounting slot of the hanging/mounting opening and the location of the end edge of the rack mounting slot are such that when the wall rails are interlocked at opposite ends the distance between such slot end edges is equal to twice the distance between each pair of rail rack wings and its associated back member end so that when the rail racks are mounted on the interlocked wall rails the rail racks are vertically aligned in closely spaced relationship.
