Shanok, Brooklyn, N.Y., assignors toGlass Laboratories Company, a limited partnership of New York Filed Feb. 8, 1967, Ser. No. 614,712 2 Claims. (Cl. 248-115) ABSTRACT OF THE DISCLOSURE This invention is concerned with providing an improved clock supporting device adapted to be magnetically mounted upon a surface attracted by a magnetic field. Briey, the new device comprises a housing, a clock received within the housing, the housing being removably fitted in a base provided with magnetic means exposable against a magnetic surface.

Background of the invention (1) Field of the invention-This invention-relates generally to a mounting device and more particularly to an improved mounting device employable for the support of clocks or the like.

(2) Description of the prior en -The use of small permanent magnets of great strength in various mounting devices is of course well known. For example they have been employed for mounting such objects as change receptables in automobiles, or ash-trays, or for attaching messages to telephone receivers by the use of magnetized clips. It is also known to utilize such magnets in providing mounting means for supporting a portable clock. However, these have resulted in an assembly that left the clock permanently attached to the mounting means, so that while the entire assembly might be portable, the clock itself was no longer portable. This is an especially serious disadvantage if the entire assembly is bulky or cumbersome, or is not easily adaptable to small mounting spaces. Moreover, if just the clock were needed because there was no requirement for the magnetic mounting means, this was not possible to achieve absent a dismantling of the entire device.

Summary of the invention It is, therefore, an object of this invention to provide an improved magnetic mounting means for the support of such devices which will be readily detachable without the need for dismantling the assembly.

It is another object of the invention to provi-de an improved magnetic mounting means as above, for use in support of a portable clock.

It is a further object of the invention to provide an improved magnetic mounting means which may be used for support and incorporation in a portable clock.

It is a still further object to provide a portable clock having facilities for the reception of an improved magnetic mounting means which will render each readily detachable from the other.

In accordance with the present invention the above objectives are achieved by an improved clock supporting device which comprises in combination a housing,va clock received within the housing, the housing being'adapted to overlie and be slidingly and detachably engageable with oppositely disposed members provided on .a base, and the bottom portion of the base receiving magnetic means exposable against a magnetic surface. The invention is also further directed to an improved supporting device comprising a member provided with oppositely disposed holding means for the device to be supported, the holding means being integral with said member, and

the bottom of the said member receiving magnetic mounting means, as above.

the clock is attached to the base by an arrow at the top of the cutaway portion.

Description of the preferred embodiments Referring now to the iigures of the drawing, one embodiment of the invention comprises a clock having .a dial 10 and housing 11, the latter receiving a conventional clock mechanism 14. Said housing is provided with inwardly sloping sides 11a which are integral with face plate 11C forming a recess 11d with the housing bottom 11b. Inwardly sloping sides 11a can be further defined as being angularly disposed such that an imaginary line drawn from each of said sides in the direction of the bottom of the clock would intersect at some point below the plane of the bottom of the clock. For reasons that will be explained subsequently the degree of angular disposition of said sides 11a is not critical and will vary depending on the construction of the base 12. The base 12 generally conforms roughly to lan H shaped structure integrally formed as a single unit which can best be seen by referring to FIGS. 3 and 6. Said base 12 is provided with oppositely and angularly disposed flanges 12a corresponding to the oppositely disposed members of the H shaped structure aforementioned. Along the horizontal portion 18 of the H shaped base 12 connecting anges 12a are provided oppositely disposed retaining members 12b forming an inverted U-shaped member (with respect to flanges 12a). Flanges 12a as above mentioned are angularly disposed and such disposition may be defined by the fact that an imaginary l-ine drawn from each of said anges in the direction of members 12b would intersect at some point below the plane of said members 12b. It is this latter disposition (i.e., of said anges) that determines the angle (or angular disposition) of sides 11a since these are adapted to overlie flanges 12a, therefore the angular dispositions must, of necessity, correspond one to the other. Additionally, anges 12a are bevelled as denoted by reference numeral 19 and said bevels are also angularly disposed, such angular disposition being defined by the fact that an imaginary line drawn from each of said bevels in the direction of face plate 11c would intersect at some point below the plane of said face plate. This can best be seen by referring to FIG. 4. It can also be seen by referring to the figure that sides 11a have the same angular disposition as the bevels 19 since as already mentioned, sides 11a are adapted to overlie and thus sheath members 12a. Indeed, as can be seen from FIG. 3, sides 11a are adapted to overlie and sheath flanges 12a. Thus said housing is adapted to overlie and be sl-idingly (and detachably) engageable with base 12 provided with oppositely disposed flanges 12a. The overlie and sheath effect should be tight enough to prevent accidental jarring, yet be loose enough to be easily removable. This is of course controlled by coordinating the angular dispositions of the parts above as kmentioned and additionally by regulating the overall length of the base 12 extending along the line of the flanges 12a. By once again referring to FIG. 4 it will be observed that base 12 is tted snugly into position, with the entire clock assembly, abutting at face plate llc. The base is preferably made of steel or other suitable magnetic rigid material, while the housing may be composed of any rigid non-magnetic material, such as preferably plastic.

The base 12 is also mountable upon any surface attracted -by a magnetic field. Thus the base 12 may bn disposed upon the at surfaces of a steel cabinet or other such equipment or on the metal dashboard of a car or truck.

To provide the magnetic iield required for the mounting of said clock, the bottom of the base 12 is provided with oppositely disposed retaining members 12b, forming an inverted U-shaped member, which house a pair of rectangular shaped magnets 15. The magnets are of the ceramic type wherein the magnetic poles are located at the upper and lower faces of the magnet so that one face attaches to the base 12 and the other to the at surface 13 to which it is intended to dispose the magnetic clock.

In one embodiment of the invention the magnets 15 are provided with central apertures 15a, through which screws 16 or other fasteners may be inserted to provide for a more permanent type of mount, said screws being inserted in like aligned apertures bored through base 12, if desired (FIG. 6). Thus it can be seen by referring to FIG. 7 that the clock and housing (shown by phantom lines) would still be slidingly and detachably engageable with the fastened base 12 into suitable support 17.

While there have been shown and described and indicated the fundamental novel features of this invention, as applied to a specific embodiment, or embodiments, thereof, it is to be understood that various omissions,

substitut-ions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art, without departing from the spirit of the invention. Y
