Description

  The present invention relates to a main body of a suspension unit movably supported in a rail for a curtain device comprising at least one rail. The suspension unit is formed as a roller unit or a sliding unit.

  For the installation of curtains, in many cases, the upper edge of the curtain is provided with a large number of suspension units, such as rollers or gliders, which are supported in a longitudinally movable manner in the rail. The rail can be attached to a ceiling or a wall, for example. Depending on the structure of the suspension unit, various problems can occur when pulling or pushing the suspension unit in the rail. For example, the friction between the individual components of the curtain device is too great, movement in the rails, for example, generation of noise due to shaking or vibration, rough movement when pulling or pushing the suspension unit, Noise due to the interaction between them.

  For example, a roller unit is known from US Pat. No. 6,057,049, in which case the body is made of a first material and the roller extending through the body is made of a second material. Thereby, the noise at the time of a roller unit moving on the sliding surface of a rail can be reduced. This roller is manufactured as one part by a two-component injection molding process. First, a shaft portion is manufactured from plastic, and subsequently, a running wheel is formed on the shaft portion, and a roller unit is mounted on the rail using this. The material for the running wheel is a plastic material that is elastic and therefore reduces noise. By injecting this material into the running wheel area outside the shaft part via an axial groove in the shaft part, the roller also has a filling part that reduces noise by filling this groove as well. It is not foreseen to suppress the generation of noise by the main body carrying the roller.

  Patent document 2 shows the glider provided with the base for inserting in a rail. This base has a one-piece elastic carrier element made with two-component technology. This elastic carrier element acts as a catch-snap connection between the glider and the rail. Two-component technology allows a specific design of the elastic bearing element so that it can be easily inserted into the rail. Such a structure does not take into account the problems mentioned above as examples when the suspension unit moves in the rail. On the contrary, this elastic material acts as a brake in the rail.

  An object of the present invention is to provide a suspension unit for a curtain device and a curtain device, which alleviates the above-mentioned problems and contributes particularly to noise reduction during the operation of the curtain device and facilitates the operation of the curtain device. It is to be.

  This object is achieved according to the invention by a suspension unit according to claim 1 and a curtain device according to claim 15. Advantageous embodiments and further examples are described in the dependent claims.

  A suspension unit for a curtain device according to the present invention has a main body for connecting a guide element to a first end and for connecting a curtain suspension to a second end. The guide element is provided for guiding the suspension unit in a curtain guide of the curtain device, for example a rail or a guide rail. The guide element can be pulled or pushed along the curtain guide. The curtain hanging unit is provided for attaching a curtain to the hanging unit, and is, for example, a ring, a hook, a string hole or the like. According to the invention, at least the body consists of at least two different material parts of different hardness. That is, at least a first hard material portion and a second soft material portion are provided, and the hard material portion is harder than the soft material portion. These different material portions may be made of materials having the same material but different material properties with respect to hardness. However, it is also possible to use different substances for the hard material part and the soft material part. The body of the suspension unit is preferably formed as a two-component body. However, it should not be excluded to use a third or further material part of the suspension unit that is different in hardness from the first and second material parts.

  By constructing the main body from two material parts of different hardness, the main body can be used, for example, when the hanging unit is activated, i.e. when opening or closing the curtain, for example by pulling the curtain in the curtain guide. Tensions and vibrations caused by movement of, or by interaction with the curtain guide or by force action by pulling can be at least partially absorbed or damped. Thereby, generation | occurrence | production of the noise at the time of the action | operation of a curtain is reduced, and the force effect | action required for curtain operation is reduced.

  The hanging unit is suitable for the installation of all types of curtains with curtain guides, e.g. suitable for fabric curtains or vertical blinds for sunshades and room partitions in windows and walls.

  The body of the suspension unit is formed as a frame with side posts or a kind of open housing. In essence, the body is preferably box-shaped and comprises the guide element at the upper first end and the curtain suspension device at the lower second end. The struts are preferably provided on the outer edge of the body and extend from the upper end to the lower end, and these ends form the end of the body. The frame is preferably made of a hard material, and at least the intermediate space between the struts on the opposite face of the body is covered or filled with a soft material. This hard material gives the frame a certain stiffness, while the soft material helps support and relax. The internal space between the struts can be covered with a soft material or at least approximately filled. That is, the inside of the frame or each support column and the inside of the terminal end can be covered with a soft material. The interior space can also be completely filled with a soft material. Preferably, the frame has an enclosed region of hard material in a circumferential direction surrounding the upper and lower ends and / or in a circumferential direction surrounding the side posts. Therefore, there is an uninterrupted region of hard material around at least one of these circumferential directions. This structure provides stability to the body.

  In order to hold the curtain, a large number of suspension units are generally arranged in the curtain guide of the curtain device. In one variant of the body in which the opposing surfaces are filled with a soft material, these opposing surfaces are preferably located in the pulling direction of the suspension unit, so that the front and rear surfaces of the body are also formed in the pulling direction. Is done. The front and rear surfaces of the main bodies of the individual suspension units are located facing each other and may collide with each other when moving in the curtain guide. Preferably, the soft material protrudes beyond the frame struts at least in the direction of impact. Therefore, the suspension units can collide with each other on the surface made of a soft material, thereby mitigating the collision and thus the noise caused by the collision.

  This relaxation characteristic depends on the one hand on the type of substance used and on the other hand on the volume fraction or mass fraction of the material part. These are tailored to the particular curtain device situation. In principle, the same substance with different hardness can be used for the hard material part and the soft material part. For example, polyoxymethylene (POM), polypropylene (PP), or polyamide (PA) can be used. However, different materials can be used. These substances are particularly suitable for hard material parts. Soft material parts are known, for example, under the names Santoprene (TM), polyether block amide or PEBA or Pebax (R), Hytrel (R), Crastin (R) PBT or ABS Novodur (R). Can be used.

  In the body according to the invention, for example, the intermediate space volume between two struts made of hard material can be filled with soft material. The internal space between the columns of the main body may be ausle-kleideted with a soft material. Preferably, the body has a soft material in the upper region between the struts to which the guide elements are connected. This soft end region can form a kind of relaxation cushion for the guide element. In this case, the soft material part is not exclusively located outside the body, but the body is terminated exclusively by the hard material. The hard material portion can, for example, surround the end of the frame and straddle between the struts of the frame.

  Said guide element has a connection (44) or a shaft (8) through a region (11) filled with a soft material of the body (1).

  In the first embodiment of the suspension unit according to the present invention, a roller device is provided as a guide element at the first upper end of the main body, and is the roller device supported so as to be able to roll on the curtain guide? Or put. The roller device has a shaft that passes through a portion of the body that is filled with a soft material. This portion may be, for example, the soft end region of the frame described above. As already known, the roller device preferably has two rollers which are connected to the shaft and project beyond the body on both sides so that they rest on the curtain guide of the curtain device. Can roll. The movement of the roller or shaft in the body can be mitigated by the soft area. Furthermore, when pulling or pushing the curtain, the operation of the suspension unit is relaxed and transmitted to the rollers. As a result, vibrations and vibrations generated when the suspension unit moves are hardly transmitted to the main body.

  Preferably, a bearing sleeve made of a hard material is provided in a region filled with a soft material at the end of the body, through which the shaft of the roller device extends. The bearing sleeve is relaxed and held in a soft material part. Alternatively, the bearing sleeve may be connected to the hard material of the body, for example by crossbars or ribs. On the other hand, the hard material of the bearing sleeve can reduce the friction when the shaft rotates in the bearing sleeve compared to the soft material. This makes it easy to pull or push the curtain. The bearing sleeve may be formed as a bearing bush and can reliably guide the roller device.

  The roller device itself can also be produced by a two-component molding method (Zweikomponen tenbauweise). Preferably, the shaft has a hard material on the outside, e.g. good sliding in the bearing sleeve, and the roller is a soft material at least on the outside so that rolling on the curtain guide is mitigated Have

  In the second embodiment of the suspension unit according to the present invention, a sliding element is provided as a guide element at the first upper end of the main body, and the sliding element is slidably supported on the curtain guide. The outside of the sliding element that contacts the curtain guide is made of a hard material. This outer hard material facilitates sliding on the surface of the curtain guide as compared to a soft material. Preferably, the sliding element has a soft material in the inner region. For example, the sliding element can be formed around a soft area at the end of the frame, as described above. The hard material outside the sliding element can be connected to the frame of the body. For example, the sliding element is formed as a terminal end of the body. However, the hard material of the sliding element can also be present away from the main body frame struts and can be connected to the main body via the soft inner region. Alternatively, the sliding element may be a separate element of the suspension unit and is supported in the body of the suspension element, for example in the soft end area of the frame, as described above for the roller device. May be. The material or substance used for the sliding element substantially corresponds to the material or substance of the body.

  In one variant, the suspension unit can receive the guide element in a floating state, so that the guide element can move slightly relative to the body. This floating support is preferably produced by receiving a guide element in the soft material part of the body. The guide element can be supported on the body, for example, by a connection or shaft extending through an area of the body filled with a soft material. This soft material is sufficiently flexible that it can flex slightly as the guide element moves. This allows the guide element to move slightly relative to the hard material part of the body. Such support is obtained, for example, by receiving the roller device or the shaft of the sliding element in a soft material part. In particular, acceptance in the floating state is obtained by supporting the bearing sleeve with a soft material part. As described above, the movement of the guide element can be mitigated by the floating support.

  In one embodiment of the suspension unit, the soft material portion of the body at the second end of the body has a support surface made of a soft material for the movable support of the curtain suspension device. This support surface can be provided, for example, by a slit or opening, through which an anchor-like widerlager of the curtain suspension device can extend, so that this support is soft material Firmly contact the top. Alternatively, the curtain hanging device can be fixed to the main body and integrally formed.

  A further aspect of the present invention is a curtain unit comprising a suspension unit and at least one curtain guide and at least one curtain, wherein the curtain guides the suspension unit within the curtain guide. An advantageous configuration of the main body for a curtain device suspended in a plurality of suspension units comprising: This suspension unit is formed by the above features.

  1 to 14 show different embodiments of a suspension unit for a curtain device according to the invention with different guide elements, the suspension unit comprising a body 1 and a curtain suspension for attaching a curtain to the body 1 It comprises a device 2 and a guide element 3 for guiding the suspension unit with a curtain guide of the curtain device. The guide element 3 is connected to the first upper end of the main body 1, and the curtain hanging device 2 is connected to the second lower end of the main body 1. The main body 1 consists of at least two different material parts with different hardness. For example, the main body is manufactured by an injection molding method. Materials or substances as described above are used. The same reference symbols are used for equivalent elements in different embodiments having equivalent functions. In particular, since the main body 1 of different embodiments has a similar structure, the description can be referred to for all the embodiments.

  FIG. 1 shows a first embodiment of a suspension unit for a curtain device according to the invention comprising a guide element in the form of a roller device. The structure of the main body 1 will be described with reference to FIG. The main body 1 includes a hard material portion 20, a soft material portion 30, and a bearing sleeve 12 made of a hard material. The hard material portion 20 and the soft material portion 30 can each be composed of hard or soft material, or multiple regions of such material. In the exploded view, the individual parts are shown as separate elements for clarity, but the body is formed as one piece.

  The hard material portion 20 is formed as a frame and has side posts on the four edges of the hard material portion. An open intermediate space in the form of a window-like opening 18 is formed between the support posts 4 on the front and rear surfaces. The frame is open on both sides. The struts 4 are connected to each other by an end 6 in the form of an arched bridge on the top and a bottom element 16 on the bottom. The bottom element 16 is provided with a slit or slot for inserting a curtain suspension device. An internal space 17 of the frame is formed between the columns 4.

  The soft material portion 30 is formed to fit snugly into the interior space 17 of the hard material portion 20 and abuts the inside of the hard material portion except in the region of the bottom element 16 without soft material. In particular, the soft material portion 30 has the intermediate space filling portion 5, the upper soft region 11, and the intermediate soft region 15 on the front and rear surfaces. The intermediate space filling portion 5 enters between the columns of the hard material portion 20. The upper soft region 11 has an axial passage 19 that extends at right angles to the direction of pulling or pushing the suspension unit from one side of the body to the other. The middle soft area 15 fills the interior space 17 in approximately the upper half of the body, so that the middle space 14 remains empty in the lower half of the body. An extension 13 protrudes downward from the middle soft region 15, and this extension 13 forms an inner lining of the column 4.

  The bearing sleeve 12 is formed from a sleeve having a length such that the sleeve projects outwardly slightly beyond the passage 19 of the soft material portion 30. This is also referred to in FIG. The bearing sleeve 12 has a large number of ribs 21 around it, and these ribs 21 are located in the grooves on the inner periphery of the passage portion 19.

  As can be seen from FIG. 1, the intermediate space filling portion 5 of the soft material portion protrudes beyond the support 4 of the hard material portion at the front and rear surfaces. In the remaining area surrounding the periphery of the body, the outside of the body is made of a hard material. On the front and rear surfaces of the main body, a soft material is exclusively on the outside.

  The curtain suspending device 2 is inserted into the bottom element 16 of the hard material part 20. This curtain hanging device has a ring-shaped curtain attachment 9 at the lower end. An anchor element 10 is provided at the upper end, which is suspended from the bottom element 16 and is located in the intermediate space 14 of the body 1. Instead, other forms of curtain hanging devices are possible, such as those shown in the embodiments of FIGS. 11-14, or those known from the prior art.

  The upper end of the body 1 is provided with a roller device which is a guide element 3, which has a roller 7 and a shaft 8. The shaft 8 extends through the bearing sleeve 12, and the rollers 7 are disposed at both ends of the shaft 8. Since the roller 7 protrudes beyond the side surface of the main body 1, it can be placed on the curtain guide of the curtain device and guided by the curtain guide. The roller 7 is rotatable with respect to the main body 1. The shaft 8 of the guide element 3 extends through a soft area 11 above the soft material part. Preferably, the soft material in the upper soft region 11 is flexible so that the shaft 8 can move slightly within the soft region 11. Therefore, a kind of floating support of the shaft can occur. Alternatively, the bearing sleeve can be fixed to the body and the bearing sleeve can be connected to the hard material part, for example by a rigid cross or rib, so that the bearing sleeve guides with the shaft 8 fixed.

  If a large number of suspension units for guiding the curtain are inserted into the curtain guide, these units can be moved in the usual way in the longitudinal direction of the curtain guide, for example by pulling on the curtain. However, the suspension unit preferably has a drawstring attachment 22 on the side of the hard material portion 20 of the main body 1 to which the drawstrings connecting the individual suspension units can be attached. By pulling the string in one direction or in the opposite direction, the suspension unit can be moved along the curtain guide. The drawstring attachment 22 can be obtained using, for example, a clamp.

  To position the curtain, the suspension unit is moved along the curtain guide. The tension, vibrations or vibrations that occur in this case are alleviated by the soft material of the body 2 as described at the outset. When the individual suspension units collide with each other, the internal space filling portions 5 made of soft materials of the individual suspension units collide with each other, and as a result, generation of noise is reduced.

  As can be seen from FIG. 2, the bearing sleeve 12 projects laterally beyond the upper soft region 11. Thus, the roller 7 on the shaft 8 is kept away from the soft material 11 above, so that the roller 8 is not braked by the soft material.

  FIG. 3 shows the suspension unit in a longitudinal section through the front and rear surfaces. As mentioned above, the curtain suspension device 2 is suspended on the bottom element 16 of the hard material part by means of the anchor element 10 and the shaft 8 of the roller device is located in the bearing sleeve 12 in the upper soft area 11. This region 11 is covered at the top by the end 6 of the hard material frame. The internal space filling portion 5 protrudes beyond the front and rear surfaces. The internal space of the hard material frame is filled with soft material at least in the upper half by the upper soft region 11 and the intermediate soft region 15. The intermediate soft region 15 moves to the internal space filling portion 5 and the extension portion 13. An intermediate space 14 is left below the middle soft area 15, and the anchor element 10 can be fitted into the middle space 14 to be movably supported. The body has sufficient rigidity due to the structure of the hard material part so that the curtain can be guided by the curtain guide regardless of the part of the soft material.

  FIG. 4 shows a longitudinal sectional view of the suspension unit passing through both side surfaces of the main body 1. The shaft 8 of the roller device extends through a bearing sleeve 12, which protrudes beyond the upper soft area 11 on both sides. The roller 7 is fixed by a shaft lid 23 at the end of the shaft 8. There is a gap between the surface located inside the roller 7 and the surface located outside the upper soft region 11 and the terminal end 6. As already explained, the roller is composed of a hard material on the outside and has a soft material on the inside, which can be adjacent to a shaft made of, for example, a hard material.

  FIG. 6 shows a second embodiment of a suspension unit according to the invention with a sliding element as a guide element. The main body 1 and the curtain suspending device 2 correspond to those of the first embodiment shown in FIGS. The sliding element has two gliders 40 which are arranged on the left and right sides of the body 1 and project beyond the body 1. The glider 40 is formed as an element with an oval or elliptical outer periphery by which the glider is placed on or abuts the curtain guide of the curtain device and slides on the curtain guide. Can do. The glider 40 preferably has a hard material portion on its outer periphery. The glider 40 can have a region of soft material on the inside.

  As can be seen from FIG. 7, the glider 40 is supported on the main body 1 in the same manner as the roller 7 of the first embodiment. Accordingly, reference is also made to the above description. The glider 40 is substantially disposed at both ends of the shaft 8 extending through the body 1. The shaft 8 is provided in the soft end region 11 of the main body 1. The soft end region 11 reduces the movement of the glider 40. As already explained above, the glider 40 is supported floating. Between the soft region 11 and the shaft 8, a bearing sleeve 12 made of a hard material is again provided, so that when the shaft 8 rotates in the bearing sleeve 12, the hard shaft 8 and the hard bearing sleeve 12 Good slip characteristics are imparted during

  The glider 40 of the present embodiment is supported movably with respect to the main body 1. When the suspension unit moves on the curtain guide, on the other hand, the glider 40 can roll on the curtain guide at its outer periphery, thereby taking an optimum posture for the sliding motion. On the other hand, the main body 1 provided with the curtain suspending device 2 is inclined with respect to the curtain guide, so that it can similarly take an optimum posture for the movement of the suspending unit. For this reason, the suspension unit can easily slide along the curtain guide, and the force required for this can be reduced.

  FIGS. 8 to 10 provide a third embodiment of a suspension unit according to the present invention comprising a sliding element as a guide element, which is fixed to the body. The main body 1 has an upper end formed by a method corresponding to the main body of the previous embodiment. As described above, the hard material portion 20 including the end portion 6 and the support column 4, the through-hole portion 19, And a soft material portion 30 with an intermediate space filling portion 5. In this embodiment, the soft material portion 30 of the body 1 extends from the upper end of the hard material portion 20 to the lower end. At the lower end of the main body 1 there is a flat bottom element 16 on which the curtain suspension device 2 is fixedly provided. The curtain suspending device 2 is preferably formed integrally with the main body 1 and thereby becomes part of the hard material part of the suspending unit. The curtain suspending device 2 has a curved portion protruding downward from the main body 1 as the curtain attachment 9, and this curved portion forms a passage portion. As a result, the curtain is hooked to the curved portion, for example, a clip Can be attached by fastening (Anklippsen) or sewing.

  As shown in FIG. 8, the sliding element has two gliders 40 ′, which protrude on both sides in the upper region of the main body 1 and can rest on the curtain guide. The shape of the glider 40 ′ substantially corresponds to the shape of the glider 40 of the second embodiment. As can be seen from FIG. 10, the glider 40 ′ is firmly connected to each other via the elongated connecting portion 44. The connecting portion 44 is, for example, cylindrical, and has a plurality of ribs 45 extending in the longitudinal direction on the outer periphery thereof. About this connection part, it is equivalent to the bearing sleeve 12 of previous embodiment. Alternatively, the connecting portion 44 may have an elongated shape having a cornered outer periphery.

  As shown in FIG. 9, the connecting portion 44 of the glider 40 ′ is arranged so as not to rotate in the passage portion 19 of the soft material portion 30. The rib 45 engages with a recess around the through portion 19 and prevents the connection portion 44 from rotating within the main body 1. The connecting portion 44 is preferably made of a hard material. By placing the connecting portion 44 on the soft material portion 30 of the main body 1, the glider 40 ′ is supported in a floating manner with respect to the main body 1. Along with the movement of the connecting portion 44 in the material portion 30, the soft material is deformed flexibly and relaxes the movement of the glider 40 '.

  The individual elements of the suspension unit in the form of the main body 1, the curtain suspension device 2 and the guide element 3 are fixed relative to each other in this embodiment. Preferably, the suspension unit is manufactured by a two-component injection molding method as described above.

  As the suspension unit moves along the curtain guide, the suspension unit can roll on the oval or elliptical contact surface of the glider 40 ', so that the suspension unit tilts with respect to the curtain guide. Can take a posture that can move smoothly. The movement of the suspending unit along the curtain guide of the curtain device is mitigated by the soft material part of the suspending unit, which can reduce the generation of noise and facilitate the adjustment of the curtain of the curtain device. it can.

  FIGS. 11 to 14 show a fourth embodiment of a suspension unit for a curtain device according to the invention, comprising a guide element in the form of a roller device equivalent to the first embodiment. Structural elements having the same function are given the same reference numerals. The main body 1 has a hard material portion 20 and a soft material portion 30. A bearing 50 is integrated into the hard material portion 20, and is integrally formed by a crosspiece 51 at the upper end of the hard material portion 20.

  The hard material part 20 acts as a frame and again has side posts 4 at the four edges of the hard material part. The frame is open on both sides. The front and rear window openings 18 are filled by the intermediate space filling portion 5. The struts 4 are connected to each other by a terminal end 6 on the upper side and a bottom element 16 on the lower side. The bottom element 16 is provided with a keyhole-shaped opening with a narrow inlet area 53 and a circular support area 54, the diameter of the support area 54 being larger than the width of the inlet area 53. An internal space 17 of the frame is formed between the columns 4. The hard material portion 20 has a drawstring attachment 22 to which the drawstring can be secured, which string connects the individual suspension units to each other.

  With the exception of the entry area 53 of the bottom element 16 and the area above the support area 54, the soft material portion 30 is formed to fit the inner space 17 of the hard material portion 20 and abuts on the inside thereof. The soft material portion 30 has a gap 55 in this embodiment, and this gap extends parallel to the bearing 50. The gap 55 extends somewhat beyond the middle of the soft material portion 30. However, the gap may be longer. However, the gap 55 does not completely divide the soft material portion 30. The gap 55 is located approximately between the upper soft region 11 and the intermediate soft region 15. Further, the soft material portion 30 has an axial passage portion 19. The gap 55 of the soft material portion 30 and the crosspiece 51 of the hard material portion 20 are best seen in FIG. The suspension unit is actually provided as only one part, and the crosspiece 51 is positioned in the gap 55. Thereby, the soft region 11 above the soft material portion 30 and the intermediate soft region 15 surround the bearing 50 of the hard material portion 20.

  As can be seen from FIG. 11, similar to the embodiment of FIG. 1, the intermediate space filling portion 5 of the soft material portion protrudes beyond the strut 4 of the hard material portion at the front and rear surfaces. In the remaining area surrounding the periphery of the body, the outside of the body is formed from a hard material. On the front and rear surfaces of the body, exclusively soft material is located on the outside.

  At the bottom element 16 of the hard material part 20, the curtain suspension device 2 is inserted into the support area 54. A ring-shaped curtain attachment 9 is supported at the lower end of the curtain hanging device. At the upper end, an anchor element 10 is provided, which is suspended from the support area 54. On the upper side of the ring-shaped fixture, there is a horizontal support surface 56 from which a vertical extension 57 projects upward, which ends in the anchor element 10. The extension 57 is round and has two flat portions 58 facing each other. The diameter of the extension 57 in the region of the flat part 58 corresponds to the width of the inlet region 53. The diameter of the extension 57 in the round area is larger and corresponds to the diameter of the support area 54. The diameter of the anchor element 10 is larger than the diameter of the support region 54.

  In order to insert the curtain suspension device 2 into the support area 54, the extension 57 is aligned with the entrance area 53 so that it can be pushed through the entrance area 53. In the support area 54, the extension 57 is rotated about 90 °, so that the extension 57 can no longer pass through the inlet area 53. As a result, the support surface 56 is positioned below the bottom element 16, and the anchor element 10 is positioned above the bottom element 16. The curtain suspending device 2 is securely held by the main body 1 at this position.

  The upper end of the body 1 is again provided with a roller device as a guide element 3, which has a roller 7 and a shaft 8. The shaft 8 extends through the bearing 50, and a roller 7 is disposed at each end of the shaft 8. The roller 7 protrudes beyond both sides of the main body 1 so that it rests on the curtain guide of the curtain device and can be guided by the curtain guide of the curtain device. The shaft 8 of the guide element 3 extends through the soft region 11 above the soft material portion 30 as already described with respect to the embodiment according to FIG.

  FIG. 12 shows a longitudinal section through the front and rear surfaces of the suspension unit. As already mentioned, the curtain suspension device 2 is held in the support area 54 of the bottom element 16 using the support surface 56, the extension 57 and the anchor element 10. The shaft 8 of the roller device is located in a bearing 50 located in the upper soft area 11. The intermediate space filling portion 5 protrudes beyond the front surface and the rear surface. The interior space of the hard material frame is filled with at least the upper half with a soft material. An intermediate space 14 is left below the middle soft area 15, and the anchor element 10 can be fitted into this space and supported movably.

  FIG. 13 shows the suspension unit in a longitudinal section passing through both side surfaces of the main body 1. The shaft 8 of the roller device extends through the bearing 50 and projects beyond the upper soft area 11 on both sides. The roller 7 is attached to the end of the shaft 8. As shown in FIG. 13, the soft material portion 30 is narrower than the hard material portion 20 in the direction of the shaft, so that the hard material protrudes beyond the upper soft material region 11 and the intermediate soft material region 15. Thus, the roller 7 faces the hard material on its inner surface and slides more easily when rolling than with a soft material.
