Description
Background of the Invention
1. Field of the Invention
The instant invention relates generally to magnifying apparatuses and more specifically it relates to an improved lighted magnifier device.
2. Description of the Prior Art
Numerous magnifying apparatuses have been provided in prior art that are adapted to enlarge images for viewing so that people can see them more clearly. While these units may be suitable for the particular purpose to which they address, they would not be as suitable for the purposes of the present invention as heretofore described.
Summary of the Invention
A primary object of the present invention is to provide an improved lighted magnifier device that will overcome the shortcomings of the prior art devices.
Another object is to provide an improved lighted magnifier device which can be in one instance worn on the body of the user and in another instance be placed upon a flat surface so as to enlarge and illuminate various items to be better seen, especially for people with visual impairment.
An additional object is to provide an improved lighted magnifier device in which the magnifying lens can be replaced so that the magnification of the items can be enlarged and decreased as the need requires.
A further object is to provide an improved lighted magnifier device that is simple and easy to use.
A still further object is to provide an improved lighted magnifier device that is economical in cost to manufacture.
Further objects of the invention will appear as the description proceeds.
To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated and described within the scope of the appended claims.

Detailed Description of the Preferred Embodiments
Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, the Figures illustrate an improved lighted magnifier device 10 which consists of a housing 12, and a mechanism 14, within the housing for producing a light source, so that light from the light source producing mechanism 14 can be transmitted out from the housing 12. Another mechanism 16 is adjustably mounted to the housing, for enlarging an image of an object 18 being illuminated by the light from the light source producing mechanism 14.
The housing 12 is box shaped and includes a bottom wall 20, a pair of side walls 22, a top wall 24, a rear wall 26 and a front wall 28 having an aperture 30 therein. The light from the light source producing mechanism 16 within the housing 12, can be transmitted out through the aperture 30 in the front wall 28 of the housing 12.
The light source producing mechanism 14 includes a socket 32 carried within the housing 12 proximate the aperture 30 in the front wall 28 thereof. A power source 34 is carried within the housing an is electrically connected to the socket 32, while a light bulb 36 is mounted in the socket 32. The light bulb 36 is a halogen type light bulb. The light source producing mechanism 14 further includes a switch 38 mounted to the housing 12 and is electrically connected between the socket 32 and the power source 34, so that manual operation of the switch 38 can turn the light bulb 36 on and off when needed.
The image enlarging mechanism 16 includes a magnification lens 40 for enlarging the image of the object 18, a frame 42 in which the magnification lens 40 is mounted into and a pair of arms 44. Each arm 44 is pivotally mounted to one side of the frame 42 and the side wall 22 of the housing 12, so that the frame 42 with the magnification lens 40 can be adjustably positioned over the object 18 being illuminated.
The housing 12 further includes a mechanism 46 for angularly positioning the socket 32 with the light bulb 36 within the aperture 30 in the front wall 28 so that the light can be properly directed at the object 18 below the magnification lens 40.
The angularly positioning mechanism 46 includes the top wall 24 of the housing 12 having a recess 48 with a slide track 50 therein. A flip-up hood 52 is connected to the socket 32. The hood 52 has a guide member 54 so that the hood 52 can fit into the recess 48 while the guide member 54 can ride within the slide track 50 to angularly position the socket 32 with the light bulb 36.
Each arm 44 is flexible and is removably mounted to the one side of the frame 42 in a boss 56, so that the frame 42 can be removed and replaced with another frame 42 having a different sized magnification lens 4 therein. When the magnification lens 40 is changed the working distance will also be changed. The improved lighted magnifier device 10 can further include a mechanism 58, adjustably mounted to the housing 12, for enabling the device 10 to be worn on a body 60 of a user 62 of the device 10, thereby enabling the user 62 to freely utilize the hands 64.
The wearing enabling mechanism 58 includes an adjustable strap 66 extending from the side walls 22 of the housing 12 to be worn about the neck 68 of the user 62 and a pair of brackets 70. Each bracket 70 is adjustably mounted to one of the side wall 22 of the housing 12, to angular position and stabilize the housing 12 against the body 60 of the user 62.
The power source 34 is a battery 72. The power source 34 can further include an electric cord AC adaptor 74 extending from the housing 12. The electric cord 74 has a male plug 76 at its distal end 78 to connect to a wall socket (not shown).
The improved lighted magnifier device 10 can be worn on the user 62 as best shown in FIG. 1. The object 18 such as printed matter, can be held in the hands 64 of the user 64.
The improved lighted magnifier device 10 can be placed onto a flat surface 80, such as a table top or the like as shown in FIG. 4. The frame 40 with the magnification lens 42 can then be placed over the object 18, such as a watch or any other item to be viewed therefrom.
