DENTKE MIRROR. AN RETRACTOR Herman.v S's Harvey, Minersville, Pa...
Applicatibnseptember 15, 1950', SerialN'o. 1853020" 1 The present: 1113181131011 relates'to'. improvements in: dental mirrors and retractors: and more; particularly. to the type: wherein the: mirrors are. replaceable: and. the handles are of conventional structure.
An: object of the present invention is toiprovide being provided for preventing the seepage of water to the back side: of the mirrors in order that deterioration: may be. prevented.
A still further object of the present invention is to providean improved arrangement, which is smoothly contoured andprovides no sharp edges :1.
thatwould injure the tissues of the mouth- Various other objects oi the present invention include the-provisionoi means: that are simple in construction, economical, of. manufacture and of general superiority.
Still further objects of. the; present invention will. become: apparent from the detailed? description to: follow.
The best form in which I have contemplated applying my invention is clearly illustrated in the accompanying drawings, wherein:
Figure 1 is a perspective view of the entire structure of the present invention;
Figure 2 is a top plan view with the handle detached;
Figure 3 is a side elevational view showing the handle in dotted lines;
Figure 4 is a vertical longitudinal sectional view taken substantially along the plane of line 4-4 of Figure 2; I
Figure 5 is a vertical transverse sectional view taken substantially along the plane of line 5-5 of Figure 2;
Figure 6 is a top plan view of the clamping means of the present invention;
Figure '7 is a side elevational view of the clamping means of Figure 6;
Figure 8 is a top plan view of the first means of the present invention which is adapted to embrace the mirrors and disk of the present invention;
Figure 9'is' a sideelevational view of Figure 8; Figure l oi'sa detailed perspective view of the disk and angulated rod which is adapted to be positioned between the pair of mirrors in the instrument; and;
Figure I1 isone of" the mirrors to beemployed with: the present invention.
Referring more particularly to thedrawings, wherein. like numerals designate like parts throughout, the numeral IO designates generally the handle means of the present invention; the numeral t2 designates generally the diskand mirror combination, the numeral i=4 designates generally" the first means which are adapted to embracethe. mirrors and" disk combination t2 and the: numeral I6 designates generally the clamping means which is adapted to clampthe first means I4 011* the mirrors" and disk combinatiOlL The handle member l0 may be of any desired form: butsmust ofi necessity have a recessed portion. [8 whichisinternally threaded for receiving thezthreade'diend of'the angulated rod of the disk. The handle isxpreferably formed with a longitudinally grooved surface providing a firm hand; grip. I
The: handle. member l0. is formed with a reduced? diameter; and tapered portion 21 toeliminate; any sharp shoulders whichmight contact the; tissuesof the mouth and injure themthereby;
The mirrors. and disk combination 1 2-- includes therfirst el'ementlfi which isformed ofasubstantially circular and flat disk 26 to which is integrally formed the angulated rod 28. The angulated rod 28 is externally threaded at 30 whereby it may be threadedly inserted into the internally threaded recess 18 of the handle ID. A pair ui mirrors 32 and 34 are provided for positioning on either side of the disk 26. Each of the mirrors 32 and 34 is provided with a beveled peripheral portion 36.
The first means M which is best shown in Figures 8 and 9 will now be described. The first means l4 includes an arcuated rim portion 38 which is internally grooved at 40 for receiving the beveled surfaces 36 of the mirrors 32 and 34 along with the disk portion 26 which is positioned between the mirrors. The free ends 42 and 44 of the first means M are in parallel relation and radially extending from the rim portion 38, being of channel form similar to the rim portion 38.
The clamping means It, shown best in Figures 6 and 7, includes a pair of elements 46 and 48 which are of substantially flat form and are provided with arcuately cut edges 50 and 52 which form sectors of a, circle. Integrally formed at the arcuate edges 50 and 52 are a pair of arcuate channeled elements 54 and 56 which are adapted to embrace corresponding portions of the rim portion 38 of the first means I4. The plates 46 and 48 are provided with angulated portions 58 and 60 which are joined together by the conically shaped tubular element 62 which is internally threaded at 54. The major portion of the conical element 62 is provided with a conical interior which is adapted to embrace the outer angulated ends 43 and 45 of the free ends 42 and 44 of the firstmeans l4. Y Y
When it is desired to assemble a pair of mirrors 32 and 34 into the instrument of the present invention, the mirrors are positioned on either side of the disk 26 and the first means i4 is positioned therearound with the free ends 42 and 44 embracing the angulated rod 28. Next, the clamping means I6 is positioned With the threaded end 30 of the angulated rod 28 received in the tubular element 62 and the arcuate elements 54 and 56 embracing the arcuate portions of the rim 38 of the first means 14. Also, the angulated ends 43 and 45 will be positioned within the conical portion of the tubular element 62. The handie 10 may then be threadedly engaged on the outer angulated end 30 and is threaded downwardly to abutment with the outer end of the tubular element 62. Thus it will be seen that the clamping means will embrace this first means and the mirrors will be firmly held thereby. Of course the replacement of the mirrors may readily be accomplished by the reverse procedure.
From the foregoing, it is believed that an instrument has been provided which'will accomplish all of the objects hereinabove set forth.
Having described the invention, what is claimed as new is:
1. A dental mirror and retractor comprising a disk having an angulated rod extending therefrom with a threaded outer end for attachment to a handle, a pair of mirrors positionable on the faces of said disk, first means for engaging the periphery of said disk and mirrors for holding the same from displacement relative to each other, and clamping means engageable with said first means for holding the same in clamping engagement with said disk and mirrors, said first means including a channeled and substantially circular-shaped split rim portion havin the free ends thereof angulated in form and in parallel 4 relation and radially extending from said rim portion, the disk and mirrors being positionable within said rim portion and said clamping means engageable with said free ends, said clamping means including a pair of arcuately grooved elements for clamping engagement with the rim portion of said first means, a tubular element joining said arcuately grooved elements and having a conical portion thereon adapted to receive the angulated portions of said free ends of the first means and said angulated rod.
2. A dental mirror and retractor comprising a disk having an angulated rod extending therefrom with a threaded outer end for attachment to a handle, a pair of mirrors positionable on the faces of said disk, first means for engaging the periphery of said disk and mirrors for holding the same from displacement relative to each other, and clamping means engageable with said first means for holding the same in clamping engagement with said disk and mirrors, said first means including a channeled and substantially circular-shape split rim portion having the free ends thereof angulated in form and in parallel re lation and radially extending from said rim portion, the disk and mirrors being positionable within said rim portion and said clamping means engageable with said free ends, said clamping means including a pair of arcuately grooved elements for clamping engagement with the rim portion of said first means, a tubular element Joining said arcuately grooved elements and having a conical portion thereon adapted to receive the angulated' portions of said free ends of the first means and said angulated rod, and a' handle threadedly engageable 0n the threaded outer end of said rod and adapted to abut the outer end of said tubular element.
