| 1. | A curtain hanging fixture comprising of a carrier slide part (2), movable on a curtain supporting track such as an Ibeam track, and made of plastic or like material, incor¬ porating a bifurcated claw construction or a roller suspen¬ sion structure, in which the lower part is provided with a wedge (9) and a bifurcated section (3), whose upper ends (12, 13) are seated against the wedge (9) and whose lower ends have grasping jaws (7, 8), which grip the curtain material under the force exerted by the wedge (9) , located between the upper ends (12, 13), c h a r a c t e r i z e d in that the wedge (9) has a toothed structure such as to prevent the upper ends (12, 13) of the bifurcated section from slipping upwards when in the grasping position and that connecting bands (14, 15), are used to join the glide carrier (2) with the bifurcated section (3). |
| 2. | A curtain hanging fixture in accordance with claim 1, c h a r a c t e r i z e d in that one pair of the ends of the bands (14, 15) is located close to the upper ends (12, 13) of the bifurcated section while the other pair is located close to the top of the wedge (9). |
| 3. | A curtain hanging fixture in accordance with claim 1 or 2, c h a r a c t e r i z e d in that the upper ends (12, 13) of the bifurcated section are locked in a direc¬ tion perpendicular to the tightening direction in relation to the wedge (9) by means of providing the wedge and the upper part of the bifurcated section with a lateral step, e.g., an intentional seam displacement of the mold (refer to Figure 3) . |
| 4. | A curtain hanging fixture in accordance with any of claims 1...3, c h a r a c t e r i z e d in that grasping jaws (7, 8) are flexibly joined at their stems to the lower ends of the lever arms (4, 5) and have such a shaping that results in a tightening effect as they approach each other by their downwardly deflection under the weight of the curtain. |
| 5. | A curtain hanging fixture in accordance with any of claims 1...4, c h a r a c t e r i z e d in that the curtain hanging fixture is capable of being manufactured with the exception of possible support rollers as an integral piece by, e.g., molding from plastic. |
The present invention relates to a curtain hanging fixture comprising a carrier slide part, which is movable on a curtain supporting track such as a standard I-beam track, and made of plastic or like material, incorporating either a bifurcated claw construction or a roller-type suspension structure, in which the lower part consists of a wedge and a bifurcated section, whose upper ends are seated against the wedge and whose lower ends have grasping jaws, which grip the curtain material under the force exerted by the wedge.
The object of the invention is to disclose a novel con¬ struction for a simple and, consequently, cost-effective curtain hanging fixture featuring both easy placement onto the curtain track as well as an uncomplicated method for securing the curtain. The curtain hanging fixture in accordance with the invention is characterized by having a wedge with a toothed construction such that it prevents the upper ends of the bifurcated section from slipping upwards along the wedge, and having bands which connect the glide carrier part of the fixture with the bifurcated part. By means of the invention, the curtain material is firmly secured between the jaws of the fixture. If the curtain is pulled downward while being moved along the track, the wedge is respectively driven deeper between the upper ends of the bifurcated lever arms, thus effecting a tighter grip on the curtain by the jaws.
The tapering surfaces of the wedge are provided with toothing and the upper ends of the bifurcated lever arms have correspondingly shaped sharp ends, capable of mating
with the toothing. Consequently, the wedge seated between the upper ends of the arms cannot slip free from its driven position during curtain use or mounting into the fixture.
The glide carrier part of the fixture is joined by thin, flexible connecting bands to the lever arms. Thus, the glide carrier part and the bifurcated part (curtain secur¬ ing section) are integrally held together, which allows for a straightforward manufacturing process of the fixture by use of a single tool.
An advantageous embodiment of the invention includes a lateral step or mold seam displacement on the internal gripping surfaces of the wedge and the upper ends of the lever arms that prevents the parts from slipping laterally in relation to each other. Consequently, even in the lateral direction, the wedge will remain firmly seated between the upper ends of the lever arms, regardless of lateral forces.
The invention is next examined in detail with help of an exemplifying embodiment illustrated in the attached set of figures, where
Figure 1 shows a curtain hanging fixture.
Figure 2 shows the same curtain hanging fixture as Fig. 1 with the wedge partly driven between the upper ends of the lever arms.
Figure 3 is a sectional view of Fig. 2 taken along line III-III.
The curtain hanging fixture comprises a carrier slide part 2 movable on a curtain supporting track 1 and having a bifurcated claw section, which may be provided with
rollers and whose lower part contains a wedge 9 and bifur¬ cated section 3, in which the lower ends of lever arms 4 and 5 are closed together by the force exerted by the wedge 9 as a curtain 6, gripped between the arms, is gravi- tationally pulled downward. The bifurcated part 4, 5 com¬ prises two lever arms with grasping claws 7, 8 at the lower ends of the arms and a flexible joint connecting the centers of the lever arms. The tapering surfaces of the wedge 9 are provided with toothing 10, 11, while the upper ends of the lever arms 4, 5 have correspondingly shaped sharp edges 12, 13, capable of mating with the toothing. The carrier slide part 2 is joined to the lever arms A , 5 by means of thin, flexible connecting bands 14, 15. The grasping jaws 7, 8 are flexibly joined at their stems to the lower ends of the lever arms 4 and 5 with such a shaping that results in a tightening effect from their downwardly deflection under the load, i.e., the weight of the curtain. The internal gripping surfaces of the wedge 9 and the upper ends of the lever arms 4, 5 are provided with a lateral step or mold seam displacement, whose shape is achievable by the use of a plastic molding tool as is evident from the illustration presented in Figure 3.
For those skilled in the art, it is evident that the scope of the invention is not only limited to the exemplifying example described above, but instead can be varied within the context? of the claims presented hereinafter. Thus, the curtain hanging fixture construction need not necessarily be restricted to only what is illustrated in the example, but can equally as well employ any conventionally used con¬ struction such as, e.g., bifurcated sections provided with small rollers or even a totally different embodiment for different types of supporting tracks.
