Abstract

A container 1, 2 for a transparency projector (not shown) is mounted for movement on a guide 3 attached vertically to a wall. The container 1, 2 has an aperture 8' through which projection may be carried out, and further apertures 8 for cooling and electrical connections. The container 1, 2 can be attached to a part 5 sliding in the guide by a bracket 6, and fixed at the required vertical position by means of a screw 4. <IMAGE>

Description

SPECIFICATION Container means for a rotating transparency projector fixable at the required height on a suitable vertical guide The present invention relates to a container system for a projector, in particular a rotating transparency projector of a type known per se.

According to the invention there is provided a container system for a projector, said system comprising a container, a guide on which the container can be displaced and means for immobilising the container at a required height.

The projector can be used in a particularly convenient manner since it is displaceable with the aid of devices fitted along the vertical guide and can be immobilised thereon at the required height.

Furthermore, the container system is distinguished by a shape having particularly functional proportions as well as a pleasing appearance.

In order that the invention may be better understood, an embodiment thereof will now be described by way of example only and with reference to the accompanying drawing in which: Figure 1 shows a front view of an embodiment of a container system according to the invention; Figure 2 is a side view of the container system of Fig. 1; Figure 3 is a plan view of the container system of Fig. 1; Figure 4 is an exploded view of the container system of Fig. 1; and Figures 5 and 6 are sectional views along the lines A-A and B-B respectively of Fig. 2.

Referring to the drawings, the container system consists mainly of a container proper 1, 2, which is of preferably oviodal shape as illustrated, so that it is particularly functional and at the same time of pleasing appearance, and a vertical guide 3, on which the container 1, 2 can be displaced and secured at the required height by means of suitable devices.

The container itself comprises a lower hemispherical part 1 and an upper hemispherical part 2, these parts being interconnected by a preferably cylindrical part which, together with those parts, forms a single assembly and which contains an orifice 8' for a projector (not shown).

The upper part 2 can be raised; this part and the cylindrical part together have three orifices 8 for cooling the container and for admitting electrical leads for supplying current to the projector, which later can be mounted on a flat support 10.

As shown in particular in Fig. 4 in which the container system is illustrated in an exploded view, said system also comprises vertical guide 3 which can be secured to a wall by lugs 9 or other equivalent means.

The container proper 1, 2 is secured, preferably by means of screws, to a bracket 6 and the latter is welded to a slide 5 displaceable in a C-section channel 5' provided in the guide 3. The channel 5' terminates at a certain point above the ground at 7 and advantageously contains a number of small equidistantly spaced orifices, in each of which a knob 4 can be secured. The container 1, 2, secured to the slide 5 by means of the bracket 6 can therefore be secured, with the aid of the knob 4, at the most convenient distance from the ground depending upon the surrounding conditions and the requirements of the operator.

Persons familiar with the commercially available rotating transparency projectors will appreciate the particular functionability and ease of use provided by the container means concerned.

1. A container system for a projector, said system comprising a container, a guide on which the container can be displaced and means for immobilising the container at a required height.

2. A container system according to claim 1 wherein the container consists of two hemispheres, the upper one of which can be raised for the introduction of transparencies and the projector into the interior of the container, these hemispheres being interconnected by a cylindrical connecting part having an aperture at the front through which projection may be carried out.

3. A container system according to claim 2 wherein the container accommodates, centrally, in its interior, a disc for supporting the projector, and has, both at the top and at the side, a number of further apertures for the purpose of ventilating the container and also for admitting leads for supplying electrical energy to the projector, and for introducing a control device, if provided.

4. A container system as claimed in any one of claims 1 to 3 wherein the container is displaceably attached to the guide by a lug to which the container is secured by means of screws, said lug being of T-section and being soldered to a slide which in turn is adapted to be displaced, within a channel having a corresponding section and provided in the guide, as far as a predetermined point on the guide, said slide being adapted to be secured, by means of a knob, at a height corresponding to any one of several orifices formed equidistantly along said guide, in such a way that the container can be positioned at any required distance along the guide.

65. A container system according to any one of the preceding claims, further including means for securing the guide vertically to a wall.
