Technical Field

The present invention relates to a curtain hanger for hanging a curtain on a rail, a system of components designed to be used together and a method of manufacturing a curtain hanger according to the claims.

Background

Curtain hangers are known from the prior art, which can be inserted and removed at any position on the curtain rail. For this purpose, a slide mechanism having a head with two support projections is inserted into a guide groove of a rail having two support shoulders and then rotated relative to the rail so that the support projections land on the support shoulders of the rail.

For example, DE202011000065 specifies that, in order to move the slider from the operating position to the removal position, the support projection must be spaced from the support shoulder and/or the detent must be overcome. A disadvantage of such a slider is that this design does not ensure a secure fit of the slider in the track.

DE102010021773 provides a curtain slider with a head which can be mounted on the curtain rail by a plug-in rotary movement, for which purpose the guide section must be of compressible and resilient design and must be compressed when the curtain slider is inserted into the receiving groove of the rail. Due to its construction, such curtain sliders also do not hold the slider securely in the track and are difficult to manipulate.

Disclosure of Invention

The object of the invention is to overcome the disadvantages of the prior art and to further develop a universal device which is easy to use.

This object is achieved by a curtain hanger according to the independent claim. In particular, a curtain hanger is provided which can be easily inserted and removed at any point of the track and ensures a secure retention in the track. Other embodiments will be apparent from the dependent claims.

A first aspect of the invention relates to a curtain hanger for a track having a guide channel flanked by two support shoulders surrounding a body. The body includes a sliding head, a suspension and/or grip, and a neck. The neck region is disposed between the sliding head and the hanging and/or grip region and has a central axis. The slider has a longitudinal extension perpendicular to the central axis and a transverse extension, the longitudinal extension being greater than the transverse extension. The curtain hanger is characterized in that it has a one-piece fastener that generally surrounds the neck region of the body. The fastener and the body are arranged to be rotatable with respect to each other about a central axis such that the curtain hanger can be moved from an insertion position to a use position against a latching resistance.

The combined design as a hanging and/or gripping area allows on the one hand the use of the hanging and/or gripping area for hanging curtains, since it is designed as a hook, eye or the like and thus has an entrance or passage opening to which the curtain can be connected. At the same time, it serves as a gripping area for the user. The user may hold the curtain hanger by the hanging and/or gripping area and insert the curtain hanger into the track in the insertion position and transfer the curtain hanger to the use position by rotating the body relative to the fastener, thereby securing the curtain hanger in the track. The engaging or passage area of the hanging and/or gripping area may alternatively be designed to be closed, without eyelets, hooks or the like, and thus without an entrance or passage opening, as will be explained further below.

The inventive design with a body and a securing element allows simple and intuitive handling, a secure mounting of the curtain hook in the rail and a relatively high load-bearing capacity of the curtain hook. Thus, the design also allows for the safe support of relatively heavy window coverings on relatively small window covering hooks. This arrangement also ensures that the curtain hangers can be easily inserted anywhere on the track and also easily removed without requiring special insertion points on the track. The curtain hook is inserted into the guide groove of the rail at the insertion position until the sliding head is positioned above the support shoulder of the rail. The curtain hanger is in the inserted position when the guide head is in the track and the longitudinally extending length of the sliding head is parallel to the guide slot of the track during intended use. Subsequent rotation of the body relative to the guide element brings the curtain hanger into the use position. Then, in the use position, the transverse extension of the slider is parallel to the guide groove of the rail. In the use position, the slider rests on the support shoulder of the rail. The latching resistance prevents the curtain hook from accidentally rotating back to the inserted position and accidentally disengaging the track.

In a preferred embodiment, the fastener and the body are arranged such that they can be rotated relative to each other about the central axis from an insertion position of the curtain hook to a use position, in particular about 90 degrees. The curtain hanger, which is typically inserted or removed from the overhead position on the track by the user, can be easily and quickly manipulated by rotating about the central axis through approximately 90 degrees. Thus, the transition of the curtain hanger from the insertion position to the use position can be performed from the user's wrist and vice versa without any further gripping.

In a preferred embodiment of the curtain hanger, the body has a cam parallel to the central axis on the side of the hanging and/or gripping area facing the sliding head, and the fastener has a recess on the side facing the hanging and/or gripping area, the recess being shaped complementarily to the cam. Alternatively, the body has a recess on a side of the hang and/or grip area facing the sliding head, and the fastener has a cam on a side facing the hang and/or grip area, the cam being parallel to the central axis, the recess being shaped to complement the cam. This allows for more accurate centering of the fastener relative to the body and for simple guided rotation.

It is particularly preferred that the recess is designed such that it describes a path having a first end position and a second end position which allows relative rotation of the fastener with respect to the body. The two end positions prevent the body from rotating accidentally, thereby simplifying the operation of the curtain hanger.

In a preferred embodiment, the cam is in a first end position when the curtain hanger is in the insertion position and in a second end position when the curtain hanger is in the use position. By reaching the respective end position, the operator is prompted when the desired use or insertion position is reached. This ensures a simple and intuitive operation of the curtain hook.

In a preferred embodiment, the latching resistance is produced by designing the end positions of the recesses such that they form a positive-fit connection with the cam which can only be overcome with force. This design allows a simple and precise adjustment of the latching resistance in the manufacture of the curtain hook.

In a preferred embodiment, the recess has an access area for mounting the locking element on the body. The access region allows for easy insertion of the cam into the groove during manufacture of the curtain hanger and thus easy assembly of the fastener with the body.

In a preferred embodiment, the fastener cannot be removed from the body in a non-destructive manner, both manually and without tools. This prevents the user from accidentally removing the fastener from the body.

In a preferred embodiment, the fastener has two parallel arranged shoulders which, in the inserted position, are arranged substantially parallel to the longitudinal extent of the sliding head. The shoulder is substantially formed by a side a and a side B, respectively, wherein the side a is arranged at an angle between 45 degrees and 120 degrees with respect to the side B. In a preferred embodiment, side a and side B are at an angle of between 70 degrees and 110 degrees to each other, and in a particularly preferred embodiment, the angle is between 85 degrees and 95 degrees. The shoulder portion can make the curtain hook obtain optimum guide in the track. The length of the shoulders may be different to ensure that the curtain hooks slide safely and easily in the track even with relatively heavy curtains. The particular basic shape of the fastener is preferably cuboid. Alternatively, the basic shape can also be circular or elliptical. In a preferred embodiment, the fastener is provided with a recess opening into the centre of the fastener parallel to the length of the shoulder, whereby the neck region of the body can be inserted during assembly of the fastener with the body. In a particularly preferred embodiment, the cut-outs are outwardly V-shaped to facilitate assembly. Preferably, the length of the shoulder exceeds the longitudinal extent of the sliding head, in particular in order to ensure an optimum sliding function.

In a preferred embodiment, in the insertion position of the curtain hook, the body is arranged such that the longitudinal extension of the sliding head is oriented substantially parallel to the shoulder of the fastener, while in the use position of the curtain hook, the body is arranged such that the longitudinal extension of the sliding head is oriented substantially perpendicular to the shoulder. This ensures that the curtain hooks are accurately inserted into the guide grooves of the rail. The shoulder also ensures that the body can be rotated relative to the fastener easily and without significant axial force, since the shoulder fits securely into the guide groove of the track. Thus, the curtain hanger can be easily moved from the insertion position to the use position.

In a preferred embodiment, both the body and the fastener are injection molded. The manufacturing process is mature, economical and efficient. It is particularly advantageous that both components can be produced using the same manufacturing process.

In a preferred embodiment, the height of the shoulder and the length of the neck region along the central axis are designed such that the curtain hook can slide in the guide groove of the rail in the position of use. The dimensions can be easily modified during manufacture to ensure that the curtain hanger can be manufactured to be compatible with a variety of track sizes. This allows the curtain hanger to slide perfectly in the track at any track size.

In a preferred embodiment, the height of the shoulder and the length of the neck along the central axis are designed such that the curtain hook can be connected to the support shoulder of the rail in a non-positive manner in the use position and the curtain hook in the guide groove of the rail can be substantially prevented from being moved manually. By appropriate sizing, the curtain hanger can be used as a locking device. The dimensions can be easily modified during the manufacturing process to ensure that the curtain hanger can be manufactured to be compatible with a variety of tracks. This ensures that the curtain hanger can be made compatible with a variety of tracks and thus can perfectly secure tracks of any size. In a preferred embodiment of the curtain hanger for fastening, the access or passage opening of the hanging and/or gripping area is not provided with eyelets, hooks or the like, but is closed, so that there is no access or passage opening; in such an embodiment, the curtain hanger is designed as a pure fastening device. This has the advantage that it can be more easily distinguished from curtain hangers having a sliding function.

Another aspect of the invention relates to a system of components intended for use together, the system comprising at least one curtain hook movable in a guide channel in its use position and at least one curtain hook substantially incapable of manual movement in a track guide channel in its use position (as described above). In fact, it is common to require a curtain hook to slide in the curtain rail and a curtain hook to perform the locking function together.

Another aspect of the invention relates to a method of manufacturing a curtain hanger comprising injection molding a body and a locking element and subsequently assembling the locking element to the body. Injection moulding processes known per se are well established and have proven suitable in practice. It ensures simple, accurate, economical and efficient manufacture of the curtain hanger.

Detailed Description

All curtain hangers 1, main body 2 and fastening members 6 discussed below are preferably made of plastic and may be injection molded from the same material.

Fig. 1 shows a curtain hanger 1, a main body (shown in fig. 11) and a fastener 6 according to the present invention. The body is composed of a sliding head 3, a neck region 5 and a hanging and/or grip region 4. The fastener 6 has two shoulders, each formed by a side a and a side B (shown in fig. 2 and 7) substantially perpendicular to the side a. The curtain hanger 1 is at the inserting position. The insertion position is characterized by a transverse extension Q of the sliding head 3 oriented perpendicular to the length of the shoulder of the fastener 6 (as shown in fig. 5). In the inserted position, the curtain hanger 1 can be inserted into any position on the track and can be removed again. The body may be rotated about the central axis of the neck region 5 by approximately 90 degrees relative to the fastener 6 (as shown in figure 12A). This transfers the curtain hanger 1 from the insertion position to the use position. In the position of use of the curtain hanger 1, the longitudinal extension L of the slider 3 is perpendicular to the length of the shoulder (as shown in fig. 3A). Preferably, the body is pre-assembled with the fastener 6 and cannot be manually removed from the body in a non-destructive manner without tools. In this embodiment, the fastener 6 is rectangular parallelepiped-shaped. Also shown is a hanging and/or gripping area 4, which is exemplarily designed with eyelets for hanging curtains. But may also be designed with hooks or clips or the like. In an alternative embodiment, as shown in fig. 12B, the area 4 is designed as a pure grip area and the entrance or passage opening is designed to be closed with a plastic surface 16, so that no entrance or passage opening is present.

Figure 2 shows a curtain hanger according to the invention in the inserted position (shown in figure 1). For the sake of clarity, the curtain hanger is shown in a track 10 with guide grooves and support shoulders 13, 13'. In the inserted position, the transverse extension Q of the slider 3 is aligned perpendicular to the track. Fasteners 6 are also shown. Fastener 6 has a shoulder formed with sides a11, 11 'and sides B12, 12' substantially perpendicular thereto (as shown in fig. 7). The bottom of the fastener 6 is wider than the guide groove of the rail 10. Therefore, the fastener 6 is only partially inserted into the guide groove, so that the side surfaces a11, 11' are inserted into the guide groove. Due to their size, the sides B12, 12' cannot be inserted into the guide slots of the track 10 and act as stops when the curtain hooks are inserted into the track 10.

Fig. 4 shows the curtain hanger 1 according to the invention from one side in the inserted position. A sliding head 3, an exemplary eyelet-formed hanging and/or gripping area 4, and a fastener 6 are shown.

Fig. 5 shows a fastener 6 with a V-shaped cut and length 14 and height H of the shoulders 9, 9'.

Fig. 6 and 9 show the bottom of a fastener 6 with a groove 8 having two end positions P1, P2 and an access zone Z.

Fig. 7 shows a fastener 6 having sides a11, 11 ' and sides B12, 12 ' substantially perpendicular thereto, which together form shoulders 9, 9 '. In addition, the height H of the shoulders 9, 9' is shown.

Fig. 8 shows a fastener 6 with a V-shaped cut and shoulder length 14.

Fig. 11 shows a body 2 with a sliding head 3, a neck region 5 and a suspension and/or grip region 4 formed with an aperture. The cam 8 is also evident.

Fig. 13 shows the positioning of the body 2, the cam 7. Compared to the illustration in fig. 12A, the main body 2 is rotated about the central axis M by about 90 degrees.

Fig. 14 shows the longitudinal extension L and the transverse extension Q of the body 2 and the slider 3.

Fig. 15 shows the body 2 from above or in section a-a of fig. 13. In particular, the preferred positioning of the cam 8 is evident.

The embodiments shown in fig. 3A and 3B, 10A and 10B, and 12A and 12B differ substantially from each other because of the height H of the shoulder (shown in fig. 7) or the height H of the side B (shown in fig. 7) and the length of the neck region (shown in fig. 1, for example). Depending on the particular dimensions, various embodiments allow for a curtain hanger with a sliding function or a locking function (as shown in FIG. 1).

Fig. 3A and 3B each show the curtain hanger in the use position (as shown in fig. 1). In the example of fig. 3B, the support shoulders 13, 13 ' of the rail 10 are frictionally clamped between the slider 3 and the shoulders of the fastener 6 (as shown in fig. 7) by contact between the sides B12, 12 ' and the underside of the support shoulders 13, 13 '. It is not possible to move the curtain hooks along the track 10 without sufficient force. In the embodiment shown in fig. 3A, the sliding head 3, the shoulder of the fastener 6 (shown in fig. 7), the sides B12, 12 'and the support shoulders 13, 13' of the rail 10 are shown. The support shoulders 13, 13 'of the rail 10 are spaced apart from the side faces B12, 12' due to the longer neck region 5 and the larger shoulder height H compared to the embodiment shown in fig. 3B. In actual use, the slider 3 will rest on the support shoulders 13, 13' of the track in the position of use of the curtain hanger due to gravity. The spacing of the shoulders from the support shoulders 13, 13' enables the curtain hanger to slide without any associated effort.

Fig. 10A and 10B show side views of the fastener 6 in two different embodiments. Fig. 10A shows a fastener 6 (shown, for example, in fig. 1, 2, 3A) of a curtain hook having a sliding function, and fig. 10B shows a fastener 6 (shown in fig. 3B) of a curtain hook (shown, for example, in fig. 1) having a locking function. In each case, the length 14 of the shoulder (shown in fig. 7) is apparent. The different heights H of the shoulders are shown by comparison.

Fig. 12A and 12B show two different examples of the main body 2. While fig. 12A shows the main body 2 mainly for a curtain hook (particularly shown in fig. 1) having a sliding function (such as shown in fig. 1), the embodiment in fig. 12B shows the main body 2 conventionally used for fixing the curtain hook. The different lengths of the neck region 5 and the neck region 15 can be seen. The central axis M is also shown in fig. 12A.
