Abstract
Abstract The invention relates to a device for introducing and extracting drapery holding elements by hand or by means of an auxiliary rod in and out of an opening in the slideway of a drapery rod of a down-turned C-shaped cross-section, wherein the opening is closable by means of a removable insert piece and which comprises a channel for the drapery holding elements protruding from the channel through a slot formed between the angle portions of the C-form. The insert piece comprises a zone of C-shaped cross-section which is shorter than the opening, comprising at one end an extension insertable into the channel of the drapery rod under the angle portions thereof and comprising at the other end two elastic tongues extending the angle portions of the C zone and slidable under the angle portions of the drapery rod, the length of the C zone and tongues being greater than the length of the opening.

Claim 1
Independent Claim
229 words
The invention relates to a device for introducing and extracting drapery holding elements by hand or by means of an auxiliary rod having a C-shaped channel therein in and out of an opening in the slideway to a drapery rod of C-shaped cross-section, wherein the opening is closable by means of a movable insert piece and which comprises a channel for the drapery support elements protruding from the channel through a slot formed between the angle portions of the C-form, the insert piece comprising a zone of C-shaped cross-section which is shorter than the opening, comprising at one end an extrusion insertable into the channel of the drapery rod under the angle portions thereof and comprising at the other end two elastic tongues extending the angle portions of the C zone and slidable under the angle portions of the drapery rod, the length of the C zone and tongues being greater than the length of the opening, characterized in that at least one of the tongues (19) of the insert piece (10) carries on the outside, near its free end, a stop (22) which, when the extension (15) is pushed into the channel (6), bears against the edge (8)--associated with the tongues (19)--of the opening (7) of the C-shaped drapery rod (1) and is slidable with the tongues (19) under the angle portions (4) of the drapery rod (1).
