Description

The invention relates to a fastening device for the expansion frame of a laundry screen according to the preamble of claim 1.

From DE-GM 1 699205 a fastening device for the spreading frame of a laundry screen is known, which is mounted for longitudinal displacement on a mast and can be locked in a locking device in locking holes of the mast. The arms of the expansion frame are each held between two adapter tabs arranged in pairs on a fastening star. The connection or the storage of the individual components takes place via hinge pins. Likewise, the rope pulley and the actuating handle of the locking device are rotatably mounted via pins. Such bearings are very labor intensive and require a lot of assembly. In addition, the required bores further weaken the cross-sections of the components, which are already very small due to space constraints.

The object of the invention is to provide a fastening device which largely eliminates the need to machine the individual components and is particularly easy to assemble.

This object is achieved according to the invention with the characterizing features of claim 1.

Through the spray as ⁱ tzgussteil executed fastening star mitangeformten axes and holding hooks of the arms as well as a pre-processing of the operating handle becomes unnecessary. No drilling is required. Since the parts only have to be plugged together, the assembly can be carried out quickly and, above all, in a manner that prevents confusion. In addition, by eliminating the holes weakening the cross sections, higher strength is achieved.

Further embodiments of the invention can be found in the subclaims. These features serve to further improve operational safety and strength.

An embodiment of the invention is explained below with reference to the drawings.

On a mast 1 2 arms 3 are mounted on a mounting star. These arms 3 are supported by struts 4 at the mast end 5. The articulation of the arms 3 on the fastening star 2 takes place via a joint piece 6. For this purpose, adapter lugs 7, which are connected in one piece to an axis 8, are arranged in pairs on the fastening star 1. The adapter tabs 7 are each provided with a stub 10 on the outer wall 9 in continuation of the axis 8. With these stubs 10, the joint piece 6, in which 11 blind holes 12 are provided in resilient walls, is held. The blind holes 12 are open at the top for better demolding of the injection molded part. The intermediate joint is also provided with a mounting bevel 13. In addition, two ribs 14 are formed on the base body of the fastening star 2 at a distance next to the adapter tabs for additional lateral guidance of the intermediate joint. In connection with the mounting slope 13 and these ribs 14, the mounting of the arms 3 is only possible at a predetermined angle. The actual arm 3 is held clamped in the intermediate joint. As an additional security, an opening 15 is provided, around the wall edge 16 of which a wall region 17 of the arm is bent.

Furthermore, the joint piece 6 is provided with a trough 18 for guiding an actuating device 19 for an automatic line retraction, not shown.

Furthermore, a retaining hook 21 is formed on the base body 20 of the fastening star 2. This had hook 21 receives an axis of rotation 23 formed on the actuating handle 22. The operating handle 22 is provided at the upper end with an elongated hole curve 24 through which an axis 25 of the guide 26 for a pulley 27 is inserted. The guide 26 consists of the axis 25, which is held in a chamber 28 molded onto the base body 20, two guide rollers 29 and a guide web 30-molded onto the base body 20. The upper part 31 with the elongated hole curve of the actuating handle serves as a cable guide.

The actuating handle 22 additionally receives a latching device 32 and a compression spring 33. Furthermore, a holder 34 for a cable pull handle 35 is formed.
