CASING FOR LIGHTING DEVICE Filed June 18. v 1956 IN V EN TORs JZMss R. Buxosxy //a mm M IA/DRE BY ROBERT C. MILLER United States Patent Paul, Minn.,, assignors to Penta Incorporated; Minneapolis, Minn, a corporation of Minnesota Application June is; 1956, Serial No. 591,955.. 4 Claims. 01. Moi-16.65)

This. invention relates to animprovement in the structure. of a, casing for a lighting device. While said casing may be used in connection with various types of fighting devices; it is. here. considered with particular reference. to a dry cell' type of lighting device. commonly known as a-rflasblight.

It very often happens that inusing a flashlight the Operator wishes to direct thev beam of light ata particular angle. More often than not both of the. operators. hands will be occupied and he will attempt in some way to prop up the casingof the flashlight, hold it between his knees or attempt to squeeze it between anand his. body. These are all. very unsatisfactory ways of attempting to direct a beam of light from a flashlight. It is desirable to have a. flashlight casing so constructed that the body of the casing itself may be easily positioned to. direct itsbeam of light in one of. various different angles in relation to the. surface upon which it is resting.

It is. an. object therefore of this invention to: provide a casing for a lighting device, such as a flashlight,. adapted to be positioned to direct its. beam of light at various different angles in relation tothe surface. uponwhich it is resting.

I-tis also an object of this invention to provide a casing for a flashlight comprising a member polygonal. in form having some of its. sides respectively in planes at different angles to the planes of the other sides of said member.

It is another object of this invention to provide a casing for a flashlight having aside with. a lens mounted therein and having each of its. other sides respectively in planes which are at an angle to the. plane. of said first mentioned side.

It is another object of this invention to. provide a casing for a flashlight having a side with a lens mounted therein and having each of its other sides respectively in planes which. are. at an angle to. the. plane. of said first: mentioned side.

It is. still another object of this invention to provide a casing for a flashlight comprising a member polygonal in form having one. side. of the. lens. mounted therein and having the sides remote from said. side. each in. a plane at a diflerent angle than the plane of said side.

It isa further objectv of this invention to provide a, casing' for a flashlight comprising a member polygonal in form having a side having. a lens mounted therein having its top and end sides in planes at right angles to the planes of said side and having its remaining sides each in a plane at a different angle to the plane of said side.

It is also an object of this invention to provide a casing for a flashlight comprising a member polygonal in form having a side having a lens mounted therein having a top and bottom side in planes at right angles to the plane of said first mentioned side and having its ends respectively in planes at acute angles to the plane of said first mentioned side and having its remaining sides in planes at different obtuse angles to the plane of said first mentioned side.

These and other objects and advantages of the in- Patented June 2, 1959 2 ventionwill be fully set forthin.the.following. description made in connection with the. accompanying drawings in which like reference. characters refer to similar. parts throughout: the several views and in which:

Fig. l is a view in front elevation of applieants device;

Fig; 2. is a view in side elevation of applicantis device;

Fig. 3: is atop plan view of applicants device;

Fig. 4 is. a. view in side elevation of a modification of applicants device;

Fig. 5 is a top plan view of a modification of applicants device;

Fig, 6 is a view in side elevation of. the modification shown in. Fig. 5;. and

Fig.7 is a top plan view of a modificationof applicantls device.

Referring to Figs. l-3, applicants device. is shown comprising a casing 10. Said casingv may be. made of any suitable sheet material and is here indicated as being made of a plastic material; While said casing: 10. may take on. variousv forms, it is here. illustrated as being of. ageneral polygonal form having a face side. 10a, a. top side 101)., a bottom side 10c, ends 10 andv 10g, and sides. 10d and. 102. remote from said. face side 10a.

In the. embodiment of applicants devicehere. illustrated said remote sides 10d and10e and end. 10-1 are shown to be. respectively in planes at; angles acute. to the plane of said face side 10a. Said end 10g; isv in a plane at an. angle obtuse totheplane of said side-10a. Said other sides are shown to be in planes at right angles to the plane. of said face. side.v

Alens 11 is, mounted. in said face side 10a. Said lens will be. formed of a transparent. sheet material, such as glass or plastic. A switch 12 of a type. commonly used in flashlights will be secured to. said top side. 10b. Said lens and switch will be identical in structure, in each of the modifications of applicants device to be hereinafter described.

Said. side. 10e. will be detachablysecured in. a suitable manner to said casing 10, as by clips or other well-known means. This structure is not here. illustrated and forms no part of this. invention.

In the use of applicants device, when said casing 10 is placed in a resting position on its bottom side. 10s,, it will direct a beam of light. in a line parallel to the surface upon which it is resting. To direct a. beam of light at. an. angle tothe surface supporting said casing, said casing need only be positioned.- torest on. any one. of the sides except 10a or, 10b whereby said beam of light may quickly be directed at different angles as; desired. Thus the operator can quickly and easily change the elevation of the beam of light by merely resting" said device on diflerent of its sides. As here illustrated, said beam of light may be directed at four different angles in. relation to. theplane upon which said device. is resting. It is understood that the center of gravity of applicants device is positioned therein so that. said device may rest on and. be supported. by each of the. sides thereof as i-ndicated.

Referring to Fig. 4,. a. modification of. applicants; device showncomprising a. casing: 15. having a. face. side 15a having lens: 11 mounted therein. Said. casing has a top side 15b, a bottom side, 15c; ends 15f; and remote from said face side 15a are sides 15d and 15e. Said side 15e will be detachably secured to said casing 15 in any suitable manner as previously discussed above. Switch 12 will be mounted in said side 15b.

Sides 15b and ends 15 are shown to be in planes at right angles to the plane of said face side 15a. Said bottom side 15c is in a plane at an acute angle to the plane of said face side 15a and sides 15d and 15e are respectively in planes at angles obtuse to the plane of said face side 15a.

In the use of applicants device as illustrated in Fig. 4, a beam of light may be directed either in a line parallel to the surface upon which said device is resting, or in any one of three different angles in relation to said surface by resting said device on either its bottom side 150 or its sides 15d or 152.

Referring to-Figs. 5 and 6, another modification of applicants device is shown comprising a casing 20 having a face side 20a having lens 11 mounted therein. Said casing 20 also has a top side 20b having switch 12 mounted therein, a bottom side 2110, ends 203 and sides 20 20g, and 20h remote from said face side 2011. Said side 20g forms an inclined portion of the top of said casing and side 2011 forms the back of said casing and will be removably secured to said casing in any well known manner. The means for securing said side 20h to said casing 20 does not form a part of this invention. Said sides 20g and 2011 are respectively in planes at different angles to the plane of said face side 20a. Said sides 20 are inclined toward each other and are in planes at angles identical to the plane of said face side 20a.

In the use of applicants device as shown in Figs. 5 and 6, the operator may direct the beam of light therefrom at various different angles to the surface upon which said device is resting. This modification differs from that shown in Fig. 4 in that some of its sides are in planes at different angles in relation to the face side.

With reference to Fig. 7, another modification is shown comprising a casing 25 having a face side 25a having a lens 11 mounted therein. Said casing 25 is shown having a top side 25b having a' switch 12 mounted therein,

having ends 25c and having sides 25d and 25e remote from said face side 25a. The bottom side of said casing 25 not here shown is in a plane at right angles to the plane of the face side 2511.

The modlfication here shown in Fig. 7 is similar to I that shown in Figs. 5 and 6 with the exception that the sides 250 are inclined rearwardly toward each other directly from the face side 25:: instead of being so inclined from points remote from said face side, as shown in the modification in Figs. 5 and 6.

Thus it is seen that I have provided an efficient and very practical flashlight casing which permits the operator thereof to quickly and easily direct a beam of light in different angles to the plane of surface upon which the device is resting by merely resting the casing of said device on one or another of its sides.

It will of course be understood that various changes may be made in the form, details, arrangement and proportions of the parts, without departing from the scope of applicants invention, which, generally stated, consists in a device capable of carrying out the objects above set forth, in the parts and combinations of parts disclosed and defined in the appended claims.
