fitting

The invention relates to a fitting for generating ground clearance for suitcases or the like. Suitcase fittings of the type mentioned are known and are referred to, for example, as fitting nails. They are rigid and captive on the arranged a long narrow side of the suitcase and serve above all "to vm to protect the trunk.

It is also known to provide suitcases on wheels that can take the place of the stud and not only create an even grCssere ground clearance, but also the transport ä »m suitcase ease.

The invention is based on the object of warehousing

and warehouse planning as well as the use of the suitcase bit den en known fittings to improve.

To solve this problem, the invention provides that on Case bottom holding parts are firmly arranged and that on these replaceable support parts are fastened, and these support parts can be either ground nails or rollers.

Due to the easily interchangeable attachment of the support parts, the manufacturer of suitcases has the option of each to be provided with the relevant hardware components only after the order has been placed. It used to be In contrast, a suitcase must be fitted with either ground nails or castors at the time of manufacture was provided, which led to a considerable additional burden in storage.

Furthermore, the retailer can better accommodate the wishes of the customers because he has the option of replacing floor pegs for rollers at any time.

The particular form of attachment, the only eraSglicht an easy replacement, it appears τ description in conjunction with the claims and the drawing from ά ".

grasps «in the holding part 2, which can be fixed captively to the bottom part 5 of a suitcase with the help of thorns 3 and 4 · The spikes 3 and 4 are inserted through corresponding openings in the base part 5 and then «bent ·

The holding part 2 consists of a bearing plate 6, the one centrally arranged "elongated opening 7 old one" insertion area 8 has a greater width. The opening 7 is used to fasten a rotating part 10 carrying a roller 9 or a soil nail 11, which can be fastened in the opening 7 with the aid of a retaining pin or 13. Serve yourself for this ta the circumference of the retaining pin 12 and 13 extending grooves and 15 », which are able to accommodate the edge 16 of the opening 7. Through the grooves 14 and 15 is on each retaining pin 12 and a head 16 or 17 has been created, at the »1» inserted State of a leaf spring 18 old at its free, concave end is present. The insertion area 8 of the opening 7 is used to insert the head 16 or 17, which then helps the grooves and 15 is held securely and firmly by the bearing plate 6, after the leaf spring 18 has applied to the head 16 and 17, respectively. It is clear from FIGS. 1 and 2 and 4 that the retaining pin 12 or 13 again from the without difficulty Opening 7 can be removed when the leaf spring 18 is moved in the direction of the arrow "a" in Flg.4. This can either by “going through it directly

- 5th

409884/0058

Insertion of a pin Ib pushes the area 8 away in the desired direction. If the opening 7 in the area 8 is covered, for example, by a “soil nail according to FIG. 2, suitable and aligned bores 20 and in the bearing plate 6 or in the soil nail 11 iss can enable a pin to be released to be inserted. These bores 20 and 21 are mounted so that the pin on the leaf spring 18 applies "the 1st indicated by means of arrow ^B Ö".

The cross-section of the grooves 14 and 15 is circular, but it can also be designed differently so that the Do not know how to rotate the pin pins 12 and 13 in the opening 7. For this it is only necessary that the grooves 14 and 15 at least one straight surface lying on the edge 1 & t exhibit. The rotating part 10 consists of an approximately U-shaped cross-section serving to accommodate the roller 9 Carrier 22, which is rotatable on the bearing plate 6 with the aid of the retaining pin 12 reaching through the web of the carrier is attached.

In the exemplary embodiment shown purely schematically in FIG the support 25 and the holding part 26 can be pushed into one another. In the embodiment shown, has the holding part has a groove 27 with undercut side winds

^ 09884/0058

while the support part 25 has an I- or swallowtail shape, Has projection 28 which can be pushed into the groove 27. The groove 27 is limited by three rare walls 29 »30 and 31 · so that the support part 25 on the side wall 30 a secure and finds a firm stop.

In Figs. 6 and 7 it is shown that the holding and Support part 30 or 31 kit can be releasably fastened to one another using a screw connection according to the invention. This kind the attachment is suitable both for the soil nail and for the rotary part 33 bit of the roller 34, as Fig.7 shows.

The Flg. 8 and 9 finally give a schematic representation, that also a bayonet lock 35 for connecting the fitting parts suitable is. The holding part 36, which is rigidly fastened to the bottom of the case, has an inner or outer one for this purpose Circumferential groove 37 into which the correspondingly shaped projections 38 and 39 on the support part 40 can engage. The projections 38 and 39 are through recesses 41 and ia the holding part 36 inserted »so that they are in the groove 37 able to slide. A compression spring 43 gives the required Tension, which can also be achieved in other ways by the special shape of the hat 37. Ultimately is it possible to provide recesses 44 in the grooves 37 into which the gate projections 38 and 39 are pressed, whereby the Support part 40 receives a firm lock.

Regardless of the illustrated and described examples, there are still many possibilities to attach a fitting nail or a roller to the bottom of a case in an easily replaceable manner. Ultimately, it is also conceivable to clip them together in the simplest way, »for which the plastic components that are widely used today are excellently suited. The invention is therefore not restricted to the exemplary embodiments described; rather, changes can be made without deviating from the basic concept of the invention.
