BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention concerns a container device for a plurality of toothed key blades placed side by side and which can be selected and pushed outside the container one by one. The container is carried about in a pocket or the like with minimum encumbrance. Also, the container is arranged such that various different keys may be selected very quickly.
BACKGROUND DISCUSSION
It is already well known that the less encumbering and most used keys are of the YALE kind, and that those keys, even being each very small and light, once assembled in a group of four or five or more, become a heavy and irregular encumbrance, being particularly inconvenient for carrying in the pockets of clothes.
SUMMARY OF THE INVENTION
It is therefore the aim of the present invention to provide a container device of minimum dimension, for the housing of seven or more YALE-keys. The container device is dimensioned and arranged such that individual keys can be selected and moved one by one into operationable position external to the housing.
BRIEF DESCRIPTION OF THE DRAWINGS
The present invention will be described in more detail hereinbelow according to the attached drawings in which a preferred embodiment of the object of the present invention is shown.
FIG. 1 shows a planar view of a of a YALE key that may be housed, together with a plurality of other keys, in the device according to the present invention.
FIG. 2 shows a perspective view of the device according to the present invention.
FIG. 3 shows a perspective view similar to that of FIG. 2 except with the cover removed to illustrate the internal details of the device.
FIG. 4 shows the internal side of the cover.
FIG. 5 shows the internal spring mechanism.
FIG. 6 shows, in detail, a possible selection and output mechanism for the keys.
FIG. 7 shows a cross-sectional view taken along cross-section line VII--VII in FIG. 3.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)
Relating to the details of the figures, the device according to the present invention comprises a container, preferably in the shape of a rectangular parallelepiped, having on one of the sides transverse to the major axis, a small rectangular opening 4. By means of a sliding tab 5, sliding inside the cover along a small longitudinal opening 6, the toothed part of the key passes through the opening 4 when it is pushed out or taken back after use.
The choice of the key to be used is performed by counting the number of clicks created upon rotation of the knurled selection wheel 7, placed on the wall opposite to the opening for the keys outlet. Each click corresponds to the outlet position of a determined key. Thus, it is sufficient to memorize the various keys according to the clicks for finding them without having to look at them. Once the key has been chosen and the toothed blade pushed out of the container, said container is used as a handle for making the key turn in the lock.
Inside the container, a slide 8, movable transversely between the elongated sides of the container, may house seven or more blades in side-by-side contact with each other. In the transversal run, said slide 8 is guided by a track 9, interrupted at a center portion 22 (FIG. 6) for the width of a blade. Each key includes, at the top of the toothed part, a part of a guide 1, with two opposite grooves: on the plane of the slide, gets inserted on the guide track, repeating the shape of the transversal section. Through said groove, that gets hooked to the track, the keys follow the transverse movement of slide 8, becoming one in the same with slide 8. interrupted at its center like the preceding track and track 14 is formed on the internal wall of the cover. Pin 15 is provided within groove 16 for the dragging of the key, and is an extension of sliding tab 5. A key that is in correspondence with the pin is free from engagement with the upper track and with the guide track of the slide due to the central notch formed in the tracks. The centered key may therefore be slid or dragged by the pin of the sliding tab,
