ATTORNEYS Patented Mar. 9, 1954 UNITED STATES PATENT OFFICE 2,671,243 CURTAIN TRACK Claim priority, application Sweden August 29, 1949 6 Claims.

The present invention is in respect of an arrangement for curtain runner boards of the kind which has one or more channels running in the longitudinal direction of the board and in the board itself, these channels being open towards one side of the board by means of a slit and in which are arranged running members for the fastening of curtains or the kind, the channels also being supplied with one or more locking instruments, in one position enabling the running members to be led into and removed from the channels and in another position prevent the running members to leave the channels.

It has heretofore been suggested to place the locking instruments at the ends of the channels. However, such an arrangement has certain disadvantages that render it unsuitable for use with cornices and it also is unsuitable for us when a curtain mantle or the kind is fastened to the edge of the board.

The above mentioned disadvantages are eliminated according to the present invention, which is characterized in that in one or mor cavities, extending into at least one channel slit, a disk which is turnable around an axle being at right angles to the plane of the board, serves as the locking instrument. This disk being shaped and dimensioned in such a way as to render it possible for the running members to be led into and removed from the channels and to enable them to pass by the disk in the longitudinal direction of the channel, and also to prevent the running members from leaving the channels at other angle positions to the disk.

The invention is further made apparent in connection with the drawing, where Fig. 1 is a bottom plan view of one form of construction according to the invention;

Fig. 2 is a cross-section taken on line AA in Fig. 1;

Fig. 3 shows a longitudinal section of a modified construction according to the invention, and

Fig. 4 is a top view of th locking member mounted in the board as shown in Fig. 3;

Fig. 5 is a bottom view of the locking member;

Fig. 6 is a cross-section taken on line B-B in Fig. 3;

Fig. '7 shows a third form of construction as seen from the bottom of the runner board, and

Fig. 8 shows a cross-section taken on line AA in Fig. '7.

The board I has two channels 2 each having a C-cross section and running in the longitudinal direction of the board with a slit open towards one side of the board. In these channels there are running members in the shape of balls 6 with books I attached to them. Curtains or 2 the like are fastened onto the hooks of these running members.

With regard to the form of construction according to Figs. 1 and 2 a disk 4 rotatably mounted on a screw 5 is positioned in a cavity 3 of the board between the channels 2. The disk 4 has semi-circular recesses 4 formed in opposite sides thereof. In Figs. 1 and 2 the disk is shown when closed. When the disk is turned at 90, the cavities 4 are brought to lie facing the channels 2, thus rendering it possible to remove the balls from the channels or to lead them into the channels through the opening thus formed. As shown in Fig. 2 slots are formed at 8, whereby the openings for inserting or removing th balls become larger.

In regard to the method of construction as per Figs. 3-6 the axle l5 of the disk 4 extends through a plate 9 which lies in a cavity 3 between the two slits 2 of the channels of a board I As will be noticed said disk is fastened to the axle IE on the inside of plate 9 and rests in a cavity H in plate 9. An operating button I3 is fastened to the axle on the exterior of plate 9. The plate 9 is in its turn fastened to the board I by means of two screws Ill. The plate has two semi-circular side recesses l6 which, when the disk is placed so as to be open makes it possible for the balls 8 to, be inserted or removed from.

the channels. In Figs. 3-6, however, the disk 4 is shown when in closed position. The axl l5 has at its inner end a head l4 positioned in a cavity I2 of board l According to the forms of construction as per Figs. 78 the thickness of the disk 4 is such that it extends down to such depth of the channel 2' that the insertion or removal of the running members 6 from the channel is simplified without special measures having to be taken.

Further, in accordance .with the form of construction disclosed, the side or sides of th disk 4 that are turned towards a channel, when the position of the disk is for preventing the running members escape from the channels 2 are lying contiguous with the wall of said channel, which facilitates the passing-by of the disk by th running members in the longitudinal direction of the channel and prevents the turning of the disk when the running members pass by.

The curtain running board l has two channels 2*, in which are placed the running member 6 with hooks 1 for hanging up curtains or the kind. A disk 4* is turnable around an axle, consisting of a screw 5 The thickness of said disk, i. e. the cavity for the disk is so deep, that it reaches down to the widest part of the circular channels 2 The disk 0 is shown when in locked position.

When it is turned to 90, the cavities 4 in the disk will lie turned towards the channels 2 These cavities 4 make it possible for the running members 6 to be inserted or removed from the channels 2 When the disk according to the designs is in such a position that it prevents the running members from leaving th channels, both sides of the disk that are turned towards the channels 2 extend contiguous with the wall of the channel 2 Naturally the method of construction shown can be made to vary within the frame of theinvention.
