Lateral pull roll-up blind

An elongated lateral pull roll-up blind using only a minimum number of interchangeable connectable parts compared to that of similar prior art comprising

• two carriers forming respective end portions thereof,
• an aperture member cooperating with one of said carriers,
• a drive including
• a take-up shaft;
• a driving wheel;
• an elongated, pulling ellement trained about said driving wheel;
• a housing member having an internal space for receiving said driving wheel, and being formed with outlet openings for the passage of said pulling element,
• an end face facing in the direction of said aperture member, and
• a pin extending from the remainder of said housing oppositely to said direction, so as to face the other of said carriers;
• said aperture member supporting an end of said take-up shaft facing said one of said carriers, said aperture member also having an end face;
• means for respectively releasably mounting one and the other of said housing and aperture members on one and the other of said carriers, including
• first connecting formations provided at said end faces of said members, and
• second connecting formations compatibly engageable with said first connecting formations provided at said carriers,
• said first and second connecting formations being distributed at respective equal angular distances each along respective distribution circles of said member which are commensurate with other distribution circles of said carriers and are situated within the outline of said driving wheel at said housing member for connecting said members with said carriers against angular displacement relative thereto about the axes of the respective distribution circles in a number of different angular positions corresponding to the distribution of said connecting formations;
• clamping means releasable by pulling on said pulling element and including a clamping winding spring arranged around said pin of said housing member to releasably engage the same and having actuating portions;
• and
• plug-in entrainment means for releasably connecting said driving wheel with said take-up shaft, including an entraining disc connected to the other end of said take-up shaft for joint rotation therewith, rotatably mounted on said pin of said housing member, and drivingly connected with said driving wheel through said actuating portions of said spring,
• wherein said pin of said housing member bounds an internal bore;
• and
• wherein said entraining disc has a disc portion and a bearing pin which rotatably mounts said disc portion in said bore of said pin of said housing member, and which is constituted by a plurality of individual segments that have free ends remote from said disc portion and provided with respective bulges for snap-action arresting in said pin of said housing member,
• whereby said carriers can be mounted in installation locations extremely close to walls, ceilings,
• other upright blocking arrangements and in niches, but said drive can be located either on the right or on the left of said roll-up blind, and said drive and said take-up shaft can be replaced without having to dismount said carriers from said installation locations.
