Description

[0015] The invention will be further elucidated with reference to the following figures, in which:

[0016] FIG. 1A is an isometric view of the first preferred embodiment of the assembly according to the invention in operation;

[0017] FIG. 1B is an exploded view of the first preferred embodiment of the assembly according to FIG. 1A;

[0018] FIG. 2A is an isometric view of the second preferred embodiment of the assembly according to the invention in operation;

[0019] FIG. 2B is an exploded view of the second preferred embodiment of the assembly according to the invention according to FIG. 2A;

[0020] FIG. 3A is an isometric view of the third preferred embodiment of the assembly according to the invention in operation; and FIG. 3B is an exploded view of the third preferred embodiment of the assembly according to the invention according to FIG. 3A.

[0021] The same numerals in the shown figures designate the same components.

[0022] FIG. 1A is an isometric view of the first preferred embodiment of assembly 1 according to the invention during operation. Assembly 1 comprises a tassel 10 and a wall element 20. Assembly 1 is shown in operation, wherein tassel 10 is connected to control loop 3 and wall element 20 is fixed to a wall (not shown). Because tassel 10 can move in vertical direction relative to wall element 20, tassel 10 can tension the control loop 3 of a screen (not shown) with its own weight.

[0023] FIG. 1B is an exploded view of the first preferred embodiment of assembly 1 according to FIG. 1A. Tassel 10 is substantially constructed from a body 11 and control loop guide means 12 for the control loop. The control loop guide means 12 are connected to body 11 by means of known connecting techniques, such as a screw shown in FIG. 2. Wall element 20 and tassel 10 are configured to guide at least a part of body 11. Body 11 comprises for this purpose a guide slot 13 on the longitudinal side thereof, and wall element 20 is provided with four guide elements 21. After fixing of wall element 20 to the wall (not shown), tassel 10 can be attached to wall element 20 by sliding the body 11 in guide elements 21 by means of guide slot 13. A limiting element or base 14 is then connected to body 11, after which the control loop guide means 12 are arranged on body 11.

[0024] FIG. 2A is an isometric view of the second preferred embodiment of assembly 100 according to the invention in operation. Assembly 100 comprises a tassel 110 and a wall element 120. Assembly 100 is shown during operation, wherein tassel 110 is connected to control loop 3 and wall element 120 is fixed to a wall (not shown). Because tassel 110 can move in vertical direction relative to wall element 120, tassel 110 can tension control loop 3 of a screen (not shown) with its own weight.

[0025] FIG. 2B is an exploded view of the first preferred embodiment of the assembly according to the invention. Tassel 110 is substantially constructed from a body 111 and control loop guide means 112 for the control loop. The control loop guide means 112 are connected to body 111 by means of known connecting techniques, such as a screw shown in FIG. 2. Wall element 120 and tassel 110 are configured to guide at least a part of body 111. Wall element 120 is provided for this purpose with an opening 121. The peripheral shape of opening 121 corresponds to the peripheral shape of body 111. After fixing of wall element 120 to the wall (not shown), body 111 is slid into opening 121. A limiting element or base 113 is then connected to body 111, after which the control loop guide means 112 are arranged on body 111.

[0026] FIG. 3A is an isometric view of the third preferred embodiment of assembly 200 according to the invention in operation and FIG. 3B is an exploded view of assembly 200. Assembly 200 has many similarities to assembly 1 of FIGS. 1A and 1B. The reference numerals of corresponding components are increased by the number 200.

[0027] Wall element 220 and tassel 210 are configured to guide at least a part of body 211. Body 211 comprises for this purpose a guide slot 213 on the longitudinal side thereof and wall element 220 is provided with a guide element 221. As in the first preferred embodiment, the form of the guide element is adapted to the form of the guide slot. The guide slot comprises an opening and an adjacent cavity or recess lying in the interior of the tassel body. In the third preferred embodiment the guide element 221 is generally spherical and the cross-section of guide slot 213 is generally circular. In the first preferred embodiment the guide elements are protrusions 21 which are arranged on either side of a plate element forming part of the wall element, and the cross-section of guide slot 13 is T-shaped or cross-shaped.

[0028] When assembly 200 is supplied the tassel 210 has already been provided with the limiting element or base 214 and has preferably already been mounted on wall element 220. The assembled assembly has to be fixed to a wall and the control loop guide means 212 have to be arranged on body 211.

[0029] The shown preferred embodiment is provided with a chain tensioner 216 which operates by means of a spring 215 and which is optional.

[0030] The invention is expressly not limited to the shown embodiments. All combinations and kinematic reversals of the described technical measures fall expressly within the invention. It is therefore also possible for the guide slot to be arranged on the wall element, and one or more guide elements on the body. The body can also take a conical or tapering form. The cross-section of the body need not be round but can take other forms, such as square. The invention therefore extends to any embodiment falling within the scope of protection as defined in the claims and as seen in the light of the foregoing description and accompanying drawings.
