1 8. Claims. (01. 250-91 This invention relates to sterilizing apparatus and more particularly to a portable sterilizing unit for use in sterilizing rooms, such as bathrooms, or-the like; A
I An object of "the invention is to providea convenient, simple and effective apparatus of the type above indicatedr Another object is to provide a portable apparatus of the above type which may bereadily moved from room to room as in the case of hotels where a large number of bathrooms are to be Another objectis to provide an apparatus of the above-type'having novel and improved-details of construction-and features of operation. "Various other objects and advantages will be apparent as the natureof-the invention is more I fullydisclosed.
Although the novel features which are believed to be characteristic of this invention are more particularly pointed out in the claims appended hereto, the invention itself may be better understood by referring to the following description, taken in connection with the accompanying drawing in which a specific embodiment thereof has been set forth for purposes of illustration. v
In the drawing Fig. 1 is atopplan view of a portable sterilizing apparatus embodying the present, invention;
Fig. 2 is aside elevation thereof; Fig; 3isan end elevation of thesterilizing apparatusyand Fig. 4f is a sectional detail taken along the line 44-0: Fig. 2. 'In the following-description and in the claims these hand rails are formed as a part of opposite legs l4. It is to be understood, however, that the handrails may be made of any suitable construction or Shape and that a specific form has been shown'merely for purposes of illustration. A vertical cylinder 20 having a reflecting surface is mounted on the top plate II. This cylinder maybe made of glass, plastic, anodized aluminum or other suitable reflecting means or may be coated with such a reflecting means.
A plurality of spaced vertical tubes 2| suited to generate and radiate germicidal rays in the ultraviolet band are spa-cedaround the periphery certain specific terms are used for convenience in referring to various details of the invention.
These terms, however, are to be given as broad will permit.
Referring to the drawing more in detail, the
invention is shown a applied to a sterilizingunit comprising a portable carriage l having top,
sides and'end plates l2 and |3 respectively and-mounted upon legs I4 carrying wheels or casters I which facilitate the'movement of' the unit from place to place. 7
In the embodiment shown, two of the wheels or casters are mounted for rotation about a fixed axiswhile the other two wheelsor casters are mounted for rotation about a variable'axis' to facilitate-the-handling of the unit and .the steer- "ing thereof as it is moved from placeto'place.
A pair of hand rails I6 provide a convenient grip for the operator. In the embodiment shown,
of the cylinder 20. The tubes 2| are shown as mounted between upper and lower contact clips 22 and 23 respectively which may be of any standard type. In the embodiment shown, four such tubes are spaced around the periphery of the cylinder 2|]. It is to be understood, however,'that the number of tubes may be varied as desired, the essential consideration being to use a number of tubes suited to distribute and radiate germicidal rays to the various parts of the room.
, The cylinder is secured in place by vertical rods 25 which are spaced around the periphery of the cylinder and extend from a cover plate 26 of the cylinder to the top plate II of the carriage. The rods 25 are so spaced as to afford protection to the tubes 2| and to shield said tubes from accidental contact with an external object.
' The top plate I] of the carriage ||l may be provided with o'ne'or more apertures 21 registeringwith the cylinder 20. The cover plate 26 may also be-provided with one or more apertures 28 disposed to register with said cylinder so as to permit escape of the rising current of hot air which may be present in said cylinder. A pair of bafile plates 30 and 3| are mounted above the apertures 28 of the cover plate 26 to shield the same. The bafile plate-30 may be provided with a set of apertures 32 to facilitate escape of the hot air received from the interior of the cylinder 20. -'I'he baflle plates 30 and 3| are spaced apart and above the cover plate 26 to provide air passage therebetween. I
In the embodiment shown the carriage I0 is provided with a semi-cylindrical bottom plate 35 whichis also'made of a reflecting material similar to the cylinder 20 His coated with such ma-' terial.
Disposed about the periphery .of this bottom plate and extending axially thereof are a plurality 'of tubes 36 similar to the tubes 2| above mentioned. These-tubes 36' are mounted betweenst'andard brackets 3l'secured to the bottubes 2| and 36. as to radiate germicidal rays around the entire able leads for connecting with the various tubes 2| and 36 so as to supply electric current thereto and may be connected to an external outlet by a flexible cable 40. A suitable timing device indicated as a timer 4| may be included in the electrical circuit and mounted on the end plate I3 of the carriage ID. The timing device is preferably connected to cut off the current after a predetermined time interval.
.The carriage is further provided with side bumpers comprising rods 45, covered by a soft material, such .as rubber 46, said rods being mounted on the side plates [2 by suitable means shown as brackets 4! and extending between opposite legs l4 so as to prevent the unit from injuring any furniture with which it may come in contact. It is to be understood that such bumper means may be extended around the entire periphery of the unit if desired.
In the operation of this device, the carriage I0 is moved into th room tobe sterilized and positioned preferably at the center of such room. The timer 4| is set for the period of time required to sterilize the surfaces of the room and the current is turned on, thereby energizing all of the The tubes 2| are so arranged 360 of the wall surface of the room and accordingly cover the entire vertical wall area, in addition to radiating such waves to the ceiling and The'tubes 36.are arranged primarily to radiate the germicidal rays to the floor of the room and, by reason of the reflecting surface 35, cover substantially the entire floor area, particularly the area beneath the unit'which is shielded from the rays from the tubes 2| by the carriage itself.
It has been found in tests that the arrangement above shown efiects a complete coverage of the exposed wall, floor and ceiling areas of the room, and in the case of bathrooms covers exposed toiletseats or the like Which are to be sterilized. The unit is particularly adapted for hotel use and has been found to quickly and effectively sterilize the rooms in which it has been used. It is to be understood, however,-that it is not in any way restricted to use in hotels or in bathrooms and that such use has been set forth merely for purposes of illustration. The unit may be used in any room where sterilizing effect is required and may be applied to creameries, food factories, kitchens, hospital rooms or the like.
be made of any suitable length or the tubes may extend beyond the cylinder, if desired, or the cylinder and tubes may be tiltedfrom the vertical to facilitate coverage of certain areas. If the proper current is availabl for the unit so that largerectiflers, transformers or the like are not required, the size of the carriage may be greatly reduced to increase the coverage obtained from the unit. In such instances, the bottom units may be omitted if the upper unit is so mounted that shadows are eliminated.
Although a specific embodiment of the invention has been set forth for purposes of illustration, it is to be understood that the invention is not to be limited thereto, but that various changes and modifications may be made therein as will be readily apparent to a person skilled in the art. The invention is only to be limited in accordance with the scope of the following claims.
