Abstract
Abstract Rolling closure guide means. The guide means comprise two vertical guide members for use in guiding the edges of a rolling closure during opening or closing operations. Two guide strips are mounted on each guide member for guiding the edge of the closure between them. In one embodiment, the guide strips are manufactured in different thicknesses so that strips of the appropriate thickness, depending on the thickness of the closure, can be mounted on the guide members to guide the closure. In another embodiment, guide strips of only one thickness are used, along with one or more spacers if needed, to guide closures of different thickness in the guide members.

Claim 1
Independent Claim
224 words
In a guide system for guiding one of two rolling closures of different thickness, the closures differing in thickness by an incremental thickness; the guide system having a minimum of at least four separate elements comprising: a guide member having a pair of opposing walls between which a side edge of a selected closure from the two closures is to be guided, and three guide strips for use with the guide member; the guide member having a size to accomodate the thickest closure, each guide strip having a guide surface for guiding a rolling closure and a mounting surface; co-operating structural means on the mounting surface of each guide strip and on the inner faces of the opposing walls of the guide member for detachably mounting each guide strip on either opposing wall with its mounting surface adjacent the inner face of the wall; at least two of the guide strips being of a different thickness, the difference in thickness equal to the incremental difference in thickness between the two closures; any two of the guide strips detachably mounted on the guide member at any one time with their guide surfaces facing each other to make the guide member operative, the two guide strips selected being of a thickness to accomodate the selected closure of the two closures of different thickness to be guided.

Dependent Claim

In a guide system for guiding one of two rolling closures of different thickness, the closures differing in thickness by an incremental thickness; the guide system having a minimum of at least four separate elements comprising: a guide member having a pair of opposing walls between which a side edge of a selected closure from the two closures is to be guided, and three guide strips for use with the guide member; the guide member having a size to accomodate the thickest closure, each guide strip having a guide surface for guiding a rolling closure and a mounting surface; co-operating structural means on the mounting surface of each guide strip and on the inner faces of the opposing walls of the guide member for detachably mounting each guide strip on either opposing wall with its mounting surface adjacent the inner face of the wall; at least two of the guide strips being of a different thickness, the difference in thickness equal to the incremental difference in thickness between the two closures; any two of the guide strips detachably mounted on the guide member at any one time with their guide surfaces facing each other to make the guide member operative, the two guide strips selected being of a thickness to accomodate the selected closure of the two closures of different thickness to be guided.
Claim 3
Dependent Claim

In a guide system for guiding one of two rolling closures of different thickness, the closures differing in thickness by an incremental thickness; the system having a minimum of at least four separate elements comprising: a guide member having a pair of opposing walls between which a side edge of a selected closure from the two closures is to be guided, two guide strips and one spacer strip for use with the guide member: and the guide member having a size to accomodate the thickest closure: each guide strip having a guiding surface and a mounting surface, the spacer strip having a first mounting surface and a second mounting surface; co-operating structural means on the mounting surfaces of the guide and spacer strips, and on the inner faces of the walls of the guide member so that the spacer strip can be detachably mounted to one of the walls and so that the guide strips can each be detachably mounted to a wall or to the spacer strip, the spacer strip having a thickness equal to the incremental difference in thickness between the closures; the two guide strips mounted on the guide member with their mounting surfaces so as to have their guide surfaces facing each other to make the guide member operative, at least one of the guide strips selectively mounted directly on the guide member, or indirectly on the guide member via the spacer strip so as to have the distance between the guide surfaces on the guide strips fit the thickness of the selected closure of the two closures of different thickness to be guided.
