DE1529320B - Device for the detachable fastening of a curtain rail that can be raised and lowered by means of a suspension cable - Google Patents

Description

In this situation, when the tension on the rail cords /, J ₁ , / _2, the upper crossbar O ₁ sits on the clamping cam b , as shown in FIG. 3 shows, so that the curtain rail α together with the curtain is held in an elevated position. If the weight d together with the clamping roller / and clamping cam b is pivoted upwards by pulling on the opening cord i , FIG. 4, the curtain rail α can be lowered _{by means of the rail cords Z 1} , / _2.

For easier assembly of the carnies, it can have one or more guides ri for the longitudinal displacement of the clamping cam b, the clamping jaw c and the like camies or retaining parts.

Device for releasably securing a borrowed displacements of the curtain rod without means of a suspension cable liftable and lowerable 5 special curtain rail to be attached outside the Carniese on a Carniese, which enables a via auxiliary parts because the locking bar actuated by the clamping cams an unlocking cable operated locking bar Extends over longer areas direction with a locking lug for engaging behind one of the curtain rod, the z. B. having a curtain rail latch, thereby ge side profile can be executed,
indicates that as a locking device 10 According to an advantageous development of the Ereine the carnies (s) traversing, at their find a weight is fixed to both ends rotatably mounted pinch roller (/) connected to the pinch roller, which when pulled up by means of the Entmit provided at its end clamping - Locking cable pull the clamping roller with the clamping cams (b) and the cams cooperating with them pivoted so far that the curtain rail stationary clamping jaws (c) as an abutment for the 15 or its locking bar moves out of the locked position curtain rail (α) whose locking bar (^ ₁ ) and when the release cable slackens, the clamping cams (b) grip under it. Adjusting weight the clamping roller or the clamping cams 2. Apparatus according to claim 1, thereby forcing GE into the blocking position. The pinch roller is characterized by the fact that a locked position with the pinch roller (/) is held in the connected control weight (d) when pulling up until the release by means of the unlocking cable (z) causes the clamping by the cable will. Additional mechanical roller (/) with the clamping cams (b) as narrow as springs, which swivels downwards in the event of breakage, so that the curtain rail (a) or their falling can guide the curtain rod, are locking strips (^ ₁ ) got out of the locked position and avoided. upon release of the Entriegelungsseilzuges _v (i) 25 The invention is the pinch roller (/) or illustrated in detail by Han, "uder drawings, the adjusting weight (d). In Forcing the clamping cam (b) into the locked position. F i g. 1 is an embodiment of the invention in side cut, in F i g. 5 shown in elevation; the
30 Figs. 2 to 4 show various in side elevation Positions of the curtain rail or its locking. In the usual way, the karnise has the curtain rail serving as a curtain support, which is horizontal Position can be raised and lowered. In the The invention relates to a device 35 Carnies is a clamping roller /, which extends over the for releasable attachment of a length of the carnies by means of a support cable, rotatably mounted. In addition, the curtain rail can be raised and lowered at one of the end regions of the pinch roller / is provided with a locking device with a locking lug that can be operated via an unlocking cable cam b to hold the rail α in the high position. Has a pull cord i or the like operator gripping a curtain rail latch. 40 adjustment device is used for opening adjustment In known devices of this type (USA.- de? Pinch roller for the purpose of releasing the curtain patents 3 005 557 and 3 120 895) are in the rail. Upper part of the karnise resilient locking hook or the curtain rail α is in the karnise η means Bolts provided, which in the upper end position of the cords J ₁ , / ₂ and their guides k _v m _v k ₂ , m ₂ engaging the curtain rod in locking slots on this 45 _m horizontal position can be raised and lowered "and hold them until the Locking position to the Ab- It has along its upper and lower edge each lowering of the curtain rail via a cable pull such as a crossbar a _v a _% - arranged from which the is released. However, in order to ensure a safe catch, the upper serves as a locking bar To ensure that the curtain rail shown is in the locked position, the upper web O ₁ protrudes only on one side and to prevent it from falling down, this must be 5 ° Clamping cams b protruding away, which are retained in guided guides or even pivoted with the guide direction to the curtain rail α , these devices are provided, which requires one against one another Side of the rail a at increased expenditure on parts and assembly costs, they press in an elevated position adjacent clamping jaw c, for example, for side 55 to be attached to the wall. This clamping pivoting movement full guide parts, the pinch roller / automatically through one of her. It is the object of the invention to avoid these disadvantages in the direction of the rail α protruding of the known devices and a weight d. For the opening pivoting in the counter-stable holder of the curtain rail in the blocking direction, an opening cord engages the latter to ensure the position. 60 by means of which, in some cases, the weight d with the die is achieved according to the invention in that the clamping roller / together with the clamping cam b are pivoted through as a locking device a the carnies. When lifting the curtain transverse end, the rail α rotatably mounted at both ends by means of the cords 7, J ₁ , / ₂ , the clamping cam b is swiveled up with the clamping roller with the upper transverse _{web Ct 1} provided at its end areas when the clamping cam and the 65 gear interacting with these are swiveled up As can be seen in FIG. 2, stationary clamping jaws as an abutment for the front Then the roller / is used by the weight d hanging rail, the locking bar of which is pivoted down again by the clamping, whereby the curtain cam is engaged below. rail α is pressed against the clamping block c.
