Compartment round magazine for slides

The invention relates to one with the changing device of a projector can be used together and ^ at the same time its longitudinal axis to be rotating compartment round magazine for slides, with a compartment space in the shape of a circular ring Cross-sectional.

Up to now, in order to view different slide formats, e.g. the Formats 70 χ 70 and 50 χ ^ O, to be able to demonstrate different also use appropriately designed magazines so that the slides function correctly in terms of length ρακsenden GM'Uchorn can be accommodated, Vi as is important for the change process, among other things. " This entails considerable additional effort and makes the entire projector and accessories more expensive.

The invention is based on the object of creating a slide magazine of the type mentioned at the beginning, which can be used in the demonstration of various diaforinates, and such an increase in price can be avoided. In particular, it is supposed to be an available one Reduction of tool costs and parts costs can be achieved by the new magazine, at the same time Guaranteed good functioning of the magazine to be created.

This object is achieved with the compartment round magazine according to the invention aurch removably arranged Means for dividing oer Gefächsr in their themselves in radial Direction between the outer and inner boundary wall of the compartment extending length.

Particularly advantageous is a variant of the invention, after the means for din Gefachlängenteilung from a detachably connected. The insert to be connected to the magazine base is formed, which includes a hub that can be inserted into the center hole of the base and a ring surrounding it concentrically at a distance, the jacket of which extends parallel to the inner and outer boundary wall of the compartment of the magazine base and engages in the area of this compartment Compartment space forms an intermediate wall that limits the size of the smaller slides.

A further development of this variant according to the invention is characterized in that the circular hollow cylindrical ring of the insert is arranged and dimensioned to limit the webs radially extending only over part of the compartment space from its outer boundary wall and thus forming the compartments inward in the radial direction . A structurally particularly simple and light construction is thus possible. The jacket of the hollow cylindrical cylindrical insert ring extends advantageously up to approaching the bottom of the compartment.

Another development of the invention, however, sees before that the circular hollow cylindrical ring of the insert into an annular groove which is adapted to it and which runs over all the shed-forming webs and is worked into this engages, the webs themselves - in the radial direction from the outer to the inner boundary wall running of the compartment space in the base body - attached to these boundary walls or molded onto them are. ,

This way of developing the invention enables a particularly stable design of the novel magazine, with in addition - in the sense of the good required according to the task Function - a good safeguard against unwanted mutual contact or rubbing of the slides is created, because these are always here, i.e. also as larger formats, over their entire length from the Surrounding walls of the vessels assigned to them.

According to a further advantageous feature of the invention, the compartment-forming webs of the magazine are the alignment of the slide inserted in the magazine compartments • forming knobs, which - immediately next to the annular groove arranged and facing the compartment part receiving the smaller and larger slides - to the Slide frames come to the system leading.

In the drawings are examples of the invention, partly greatly simplified, shown.

Fig. 1 initially shows a slide magazine in section A-B of Fig. 2 without an insert.

Fig. 2 shows the top view of this magazine. Fig. 5 shows a plan view of the insert.

FIG. 4 shows the magazine with the insert, in a section corresponding to FIG.

Fig. 5 shows another magazine, namely irr.,. Section C-D of Fig. 6, without insert.

Fig. 6 shows the top view of this magazine.

Fig. 7 brings a plan view of the insert to that in FIGS. 5 * 6 magazine shown.

Fig. 8 finally shows this magazine with insert, in a section corresponding to FIG.

In the drawings, 1 is the center of the magazine body located at the receiving hole for the Hub 2 of the insert denotes which can be detachably connected to the base body. The hub 2 forms the insert together with that which surrounds it at a distance and is integrally formed on it via ribs j5 Ring 4, which is in the form of a short circular hollow cylinder is designed, with parallel to the radially delimiting walls of the Gefachraumea of the magazine body and running in the area of this compartment Lateral surfaces 4a.

The insert described divides by means of its circular hollow cylinder Ring 4 the compartments of the magazine - in the inserted state, which in some of the FIGS. sign> is - in its length, which is - undivided - in the radial direction between the outer boundary wall 5 ' and inner boundary wall 6 of the compartment space extends. In FIGS. 2, 4 and 8 are marked with 7 slides of the large format 70 x 70, which fill in the length of the compartment in full. If you put it in, you can replace the large slides 7 smaller slides 9 e.g. in the format ^ O χ 50, in the same Magazine, i.e. without changing the magazine body, can be used. Figs. 2, 4, 6 and 8 show such inserted smaller slides 9

309831/0757

The slides are each drawn with dash-dotted lines, because they are partly due to the better clarity drawn in figures, which are not just necessary for the recording of the respective slides' Show the condition of the magazine (without insert - large slides; with insert - smaller slides). From the same 2 also shows two large slides, a smaller slide 9 * and part of the circular hollow cylinder 4 of the collectible stake.

In FIGS. 1, 2, k shows how the correspondingly dimensioned circular hollow cylindrical ring 4 of the insert radially delimits or can limit the webs formed on the magazine body and extending over only part of the compartment length, forming the compartments. The circular hollow cylindrical ring extends here approximately to the bottom of the compartment. With 8 a thickening is referred to in each case at the end of the web. In a known manner, it avoids that the slides have to rest along the entire length of the web wall in order to be guided.

Another embodiment in connection with the bar arrangement of the invention show the FIGS. 5 * 6, 8. The webs are here continuously executed and on two boundary walls 5 * 6 of the Gefachraumas molded. They are labeled 12. An annular groove 11 running over all the webs takes the circular hollow cylinder Ring 4 of the insert.

This design is characterized by its particular stability, as well as the fact that a friction of the larger slides together is impossible, because these are here in any case over their entire length of V / fertilize surrounded.

ßAD ORIGINAL 309831/0757

The knobs Ij5 molded onto the web walls facilitate the alignment, in particular, of the smaller slides 9 in the compartments. The knobs 1J> are arranged so that they grasp the smaller slides 9 in the inserted state in the region of one of their longitudinal ends.

For the use of smaller slides - in accordance with the embodiment according to FIGS. 1 to 4 - on the Magazine body of the insert 2, 4 attached, wobai its annular jacket 4 engages in the groove 11 and thus forms a solid partition of the magazine, which limits the MagazinfHoher to the 35mm slide format.
