THE EQUIPMENT FOR THE YARN BAG AND THE METHOD FOR MAKING IT - ANORDNING VID TRÄDBACK SAMT SÄTT FÖR DES S FRAMSTÄLLNING

The present invention relates to a device for a basket of yarns 5 comprising a base, sides, both front and rear members made of wire mesh, wherein a frame is provided along the top edges of both sides and front and rear members extending at least sideways outwardly. the sliding rails have downwardly bent portions along their outer edges.

The invention also relates to a method of making a wire basket, comprising the steps of: manufacturing a rectangular or square frame, manufacturing the base of the wire 15, the sides, both front and rear, and attaching it to the frame.

A yarn basket of the type mentioned at the beginning is known in the art. This wire basket has a frame profile plate, with downwardly bent portions arranged along opposite sides 20 of the frame which extend longitudinally from the corners of the frame.

first, after which the downward bent parts and the stop are made.

Also, this type of wire basket cannot be rotated a 105649 while maintaining its insertion and pull-out projectors. Similarly, such a basket cannot be pivoted for optional use in the "longitudinal" or "transverse" configuration so that it can be optionally mounted in a narrow and deep cabinet or chassis or a wide, shallow cabinet or chassis.

The known type of wire basket also has a limited carrying capacity over larger widths.

It is an object of the present invention to provide the device described above in order to eliminate the disadvantages of the prior art. It is thus an object of the invention to provide a device which is simple and inexpensive to manufacture, which provides a simple arrangement of an insertion stop and a pull-out stop which is aesthetically pleasing and provides improved load capacity, particularly at high widths of the body. It is also an object of the invention to provide a device which allows the basket 20 to be freely pivotable by maintaining operation with the insertion and withdrawal stops.

The objects underlying the invention are achieved with respect to the device, if known, that the downwardly bent portions extend around the corners of the frame, at least in part along the front and rear members.

• · l.l · For the method, the purpose is achieved if: the method is characterized in that the profile material 35 having an angular or L-shaped cross-section is cut • * i! . of fixed length and bent into a rectangular or square shape to form a frame i 3 105649 and that the ends of the profile material are joined together as a seam.

In the following, the invention will be described in detail with reference to the accompanying drawings, in which Fig. 1 shows a view of an embodiment of a wireframe according to the invention, viewed from a vertical front, Fig. 2 shows a slightly modified image corresponding to Fig. 4 for sliding support, Fig. 4 is a straight rail view of Fig. 3, Fig. 5 is a sectional view taken along line 15 - A - A in Fig. 3, Fig. 6 is sectional view taken along line B - B in Fig. 3, Fig. C in Fig. 3, and Fig. 8 is an enlarged cross-sectional view corresponding to that in Fig. 6, showing. . cooperation of the wire basket with the carrying rail.

Figure 1 is a vertical front view of a first embodiment of a wire basket according to the invention. The wire basket has a base 1, sides 2 and 3, both front and back pieces 4, all made of wire ::: lattice. Along the upper edges of both the front and rear pieces 4 on the sides 2 and 3, a frame 5 extends in the embodiment shown with the same length ···. 3 0 its full dimension. Seen from above, the frame is rectangular or possibly square and * 'has slightly rounded corners.

• · ·. · The frame has an upper dimension along its length,:: a horizontal tab 6, at the inner edge of which (threaded towards the center of the basket 35) threads • · ·: ___! . in the frame forming the sides 2 and 3 of the body both front and rear 4 is secured. At least along sides 2 105649 4 and 3, the frame has at its outer edges downwardly bent portions 7 which serve as slides when the yarn basket is supported on opposing carrying rails 8 in a cabinet, stand or the like.

According to the invention, the downwardly bent portions 7 of the frame 5 extend around the corners of the frame, at least in part along the front and rear portions. However, the bent portions preferably extend downwardly along the entire length of the frame so that the frame thus obtains the same cross-sectional shape along its entire length.

According to the invention, the frame is made by cutting an angular or L-shaped profile material to a suitable length and bending it to the required rectangle or square with slightly rounded corner portions. The length of the profile material is thus aligned so that its ends meet when folded into the correct shape so that they can be joined together to form a seam. Any other post-treatment of the Ke-20 than any possible deburring and surface treatment is hardly necessary.

By forming the frame 5 in this way, the yarn basket is freely pivotable. In addition, in an application with 25 frames along the entire length having the same cross-sectional shape, one and the same basket of yarns can be used in both narrow, deep, wide and low

The rails 8 used to support the wire basket 35 in a cabinet or stand are manufactured. : reversed with right and left slides • · «. The longitudinal groove 9 having a height such that both the horizontal edge 6 of the frame 5 and the part 7 bent downwards therefrom can be slidably received on most of its lengths. Thus, the lower edge 5 of the downwardly bent portion 7 acts as a sliding surface against the lower groove interface.

At a distance from the front end of the carrier rail 8, the carrier rail has an inwardly extending arm 10 with a free end having a downwardly directed projection 10 11. The length of the arm 10 extends over the entire width of the frame 5 so that the projection 11 may engage inside the frame. In this case, the projection 11 in the overhang of the wire basket engages the back of the frame and thus prevents the wire basket 15 from being continuously extended.

To allow the wire basket to be pulled out and inserted into the carrier rail pair 8, the carrier rails have a groove 12 extending downwardly on the bottom of the groove 9 opposite the projecting arm 10. under the projection 11 of the arm 10.

In order to prevent the passage of the wire basket in use when the cabinet or stand has no <r r 25, the groove 9 has a lower limiting surface * in its groove 9 at the forward end of the carrying rail 8, directed upwards, j .; pi 13. The end 13 of the ram 13 pivoted against the front end of the carrier rail 8 has a stop 14 which is transverse, preferably approximately perpendicular, to the longitudinal direction of the carrier rail 8. When inserting a wire basket • ♦ ·. · * ·. the bent portion 7 in the front piece 4 of the wire basket rests against the stop surface 14, whereby the basket; pushing in deeper is prevented. It may be mentioned that a groove 15 is also arranged between the ramp 13 and the bottom part (vertical side surface) of the longitudinally extending groove 35 9, with the downwardly bent part 7 of the frame. --- · for the side of the frame.

Figure 2 illustrates an embodiment in which the downwardly bent portion 7 extends only around corners of the frame and ends a short distance from the front and rear portions of the wire basket 4. These portions of downwardly or downwardly extending portions 7 at front 4 function as shown above 8 with a stop surface 14.

The invention may further be modified within the scope of the appended claims.
