Abstract:
1. A support assembly comprising: a.) a vertical track component having a back side structure, a generally planar first front structure and a generally planar second front structure, the first front structure and the second front structure being spaced from the back side structure as viewed in a depth direction perpendicular to a vertical direction and the first front structure and the second front structure being spaced from one another as viewed in a width direction perpendicular to both the depth direction and the vertical direction, the back side structure, the first front structure, and the second front structure together delimiting a guide groove, the guide groove having an inlet slot that is delimited by the spacing between the first front structure and the second front structure, and the second front structure extending partially over the guide groove in the width direction so as to form an undercut between the second front structure and the back side structure; b.) a plurality of inter-engagement steps, each inter-engagement step being formed with a curved upwardly facing trough and extending in the depth direction into the undercut, the inter-engagement steps being arranged each at a vertical offset from the preceding inter-engagement step such that the inter-engagement steps are vertically staggered from one another with the inter-engagement steps each having a lower side that extends obliquely upwardly toward the back side structure; c.) a rod for supporting the inter-engagement steps, the rod and a separate sidewall each extending between the second front structure and the back side structure with the inter-engagement steps extending laterally from the rod; d.) a horizontal support component releasably engageable with the inter-engagement steps such that the horizontal support component can be releasably secured at selected vertical locations along the vertical track component to extend horizontally relative thereto, the horizontal support component having a body portion having a first generally planar contact surface and a second generally planar contact surface extending obliquely away from the first generally planar contact surface, and a single vertically elongate engagement projection generally oval in cross section with a curved bottom portion for mated receipt in the trough of the inter-engagement step, a portion of the engagement projection being adjacent to and flush with the second generally planar contact surface, the body portion extending horizontally outwardly relative to the vertical track component, the engagement projection extending perpendicularly from the body portion in the width direction and extending into the undercut of the guide groove and, in an engaged position of the horizontal support component, the engagement projection engaging a respective one of the inter-engagement steps in an engagement manner wherein the curved portion of the projection is received in the trough of the inter-engagement step and pressing against a surface of the second front structure, and the contact surface of the horizontal support component pressing a surface of the back side structure, whereby the engagement of the engagement projection with the inter-engagement step and the pressing contacts of the engagement projection with the second front structure, and of the contact surface of the horizontal support component against the back side structure together releasably secure the horizontal support component to the vertical track component, and, at each respective vertical position at which the horizontal support component is releasably secured to the vertical track component, the contact surface of the horizontal support component makes pressing contact against the surface of the back side structure at a location that is offset in the width direction from the locations of the inter-engagement steps of the vertical track component; wherein the contact surface is formed by the endmost surface of the horizontal support component and wherein the engagement projection of the horizontal support component and the contact surface of the horizontal support component are formed at a spacing from one another as viewed in the depth direction with the contact surface of the horizontal support component being in abutment with the back side support of the vertical track component in an engaged position of the horizontal support component, and the engagement projection of the horizontal support component is in abutment with the second front structure and the inter-engagement steps; and wherein during vertical adjustment of the horizontal support component the obliquely extending surface of the inter-engagement step leads the engagement projection toward the back side structure for contact of the engagement projection and the second planar contact surface with the back side structure for stability during vertical movement of the horizontal support component.
