3 Claims. (CI. 88—77)
The present invention relates generally to rear vision mirrors for use on vehicles, such as automobiles. More particularly the invention relates to that type of rear vision mirror which enables the user, by selective manipulation or adjustment thereof, to have complete or brilliant reflection under daylight driving conditions or non-glare reflection against following illuminated headlights during night time driving and its principal parts or components comprises: (Da support with an adjustable bracket whereby it may be mounted in the proper position with respect to the driver's seat of the vehicle to which the mirror as a whole is applied; (2) a mirror structure which embodies angularly disposed reflecting surfaces of different power or intensity and is tiltably mounted on the support in such manner that when it is tilted in one direction one of the reflecting surfaces is brought into the line of vision of the user and when tilted in the opposite direction to a limited extent the other reflecting surface is brought into an operative position; (3) means for limiting tilting of the mirror structure to a predetermined acute angle relatively to the support; and (4) a spring arrangement for yieldingly retaining the mirror structure in either of its tilted positions.
One object of the invention is to provide a rear vision mirror of this type which is an improvement upon, and has certain inherent advantages over, previously designed mirrors of the same general character and is characterized by high efficiency, simplicity of design, and low cost of manufacture.
Another object of the invention is to provide a rear vision mirror of the type under consideration in which the support is in the form of a two-part box-like case which houses and protects the mirror structure and has at the front thereof a substantially full sized opening which exposes the mirror structure to the user and faces towards the rear of the vehicle, and the mirror structure is in the form of an assembly which consists of a substantially rectangular frame, a conventional mirror in the rear portion of the frame and a plain glass panel in the front portion of the frame and at a small acute angle with respect to the conventional mirror.
Another object of the invention is to provide a vehicle variety rear vision mirror of the last mentioned type and character in which the assembly constituting the mirror structure is characterized by the fact that the conventional mirror and the plain glass panel are supported by the assembly frame so that the lower edges are
in abutment with one another and their upper edges are spaced apart and the frame has its upper portion in hinged or pivoted relation with the upper portion of the case.
Another object of the invention is to provide a rear vision mirror of the type and character under consideration in which the frame of the assembly constituting the mirror structure is provided at the lower margin thereof with an integral depending tongue which extends through a longitudinal slot in the bottom portion of the case, coacts with the slot defining portions of the case to limit back and forth tilting movement of the assembly relatively to the case and forms a handle whereby the user of the mirror proper may tilt the assembly back and forth in order to bring into the line of vision either the conventional mirror which affords complete or brilliant reflection or the plain glass panel which affords non-glare reflection in connection with night time driving.
Another object of the invention is to provide a rear vision mirror of the character under consideration in which the tiltably mounted assembly within the case has associated with it a one-piece stamped metal clip which is horizontally elongated, extends across the rear face of the handle forming tongue on the frame of the assembly and embodies at its ends upwardly extending hooks which extend around, and serve to hold together, the lower margins of the conventional mirror and the plain glass panel.
A further object of the invention is to provide a vehicle variety rear vision mirror of the aforementioned type and character in which the spring arrangement for yieldingly holding the assembly in either of its tilted positions consists of an inverted U-shaped wire, the lower ends of the side pieces of which are pivotally mounted and the central portion of the crosspiece of which is in interfltting relation with a downwardly facing hook on the central portion of the aforementioned clip. A still further object of the invention is to pro45 vide a rear vision mirror which is generally of new and improved construction, embodies a novel arrangement of parts and is so constructed and designed that the various components or parts thereof may be assembled with facility. 50 other objects of the invention and the various advantages and characteristics of the present rear vision mirror will be apparent from a consideration of the following detailed description. The invention consists in the several novel fea55 tures which are hereinafter set forth and are
more particularly defined by claims at the conclusion hereof.

Figure 5 is a front perspective of the rear part of the case illustrating in detail the construction, design and manner of mounting of the inverted U-shaped wire constituting the spring arrange
front compartment. The open front of the compartment faces towards the rear of the vehicle to which the mirror as a whole is applied. The top portion of the side wall 16 of the rear part of the case is provided inwards of its ends with two down-struck hinge forming spherical bosses 17. The bottom portion of the continuous side wall 16 is provided in its central portion with a longitudinally extending slot 18. The mounting bracket 12 is in the form of an arm and has at its rear end a screw thread 19 and a nut 20 whereby it may be fixedly connected to the vehicle at a point adjacent the upper portion of the windshield. The rear end of the mounting bracket is connected to the central portion of the rear wall 15 of the rear part of the case 10 by a conventional universal joint 21. The latter permits the 2o mirror as a whole to be tilted laterally or up and down into different angular positions and includes a plate 22. Such plate is riveted or otherwise fixedly secured to the front inner face of the rear wall 15 of the case rear part 13 and has 25 at the lower corners thereof a pair of vertically extending and forwardly projecting lugs 23. Such lugs project towards the front of the case, i. e., toward the rear of the vehicle and are located above and slightly outwards of the longitudinally
ment for yieldingly retaining the assembly in 30 extending slot 18 in the bottom portion of the
either of its tilted positions;

The rear vision mirror which is shown in the drawings constitutes the preferred form or embodiment of the invention. It is designed for use on a vehicle such as an automobile and serves in connection with selective manipulation or adjustment to afford the driver of the vehicle complete or full rearward vision during daylight driving or low power or non-glare rearward vision during night time driving. It is contemplated that the mirror as a whole will be positioned adjacent the upper portion of the windshield of the vehicle to which it is applied. As its main or principal components the mirror comprises a case 10 and an assembly 11 within the case.
The case 10 is of two-part design or construction and constitutes both a housing and a support for the assembly It. It is provided with a mounting bracket 12 and consists of a rear part 13 and a front part 14. Generally speaking, the case is of box-like design or configuration and possesses but a small amount of depth. The rear part of the case is preferably in the form of a one-piece sheet metal stamping. It is horizontally elongated and consists of a substantially rectangular rear wall 15 and a continuous side wall 16. The side wall is formed integrally with, and projects forwards from, the margin of the rear wall 15, and defines with the latter an open
continuous side wall 16. The universal joint 21 permits the mirror as a whole to be adjusted so that it is in the range of vision of the driver or operator of the vehicle. The front part 14 of the
35 two-part case 10, like the rear part 13, is preferably in the form of a one-piece sheet metal stamping. It consists of a continuous substantially rectangular side wall 24 and this closely surrounds, and corresponds in shape to, the con
40 tinuous side wall 16 of the rear part 13. The front margin of the continuous side wall 24 is provided with an integral inwardly extending flange 25 which engages the front edge of the continuous side wall 16 of the rear part 13 and
45 defines a substantially rectangular opening 26. Such opening is at the front of the case 10 and faces towards the rear of the vehicle. It exposes and provides access to the interior of the case 10. The rear margin of the side wall 24 is bent
50 inwards into interlocked relation with the juncture of the rear wall 15 and the rear margin of the continuous side wall 16 in order to hold the front part 14 of the case in fixed relation with the rear part 13. The bottom portion of the
55 continuous side wall 24 of the front part 14 is provided in the central portion thereof with an open sided slot 27. Such slot is the same in size as, and in registry with, the longitudinally extending slot 18 in the bottom portion of the con
CO tinuous side wall 16 of the rear part 13.
The assembly 11 is disposed for the most part within the interior of the case 10 and consists of a substantially rectangular frame 28, a conventional mirror 29 and a plain glass panel 30. The
65 frame 28 is preferably in the form of a onepiece sheet metal stamping and is shaped conformably to, but is of less size than, the interior of the case 10. It serves as a support or retainer for the conventional mirror 29 and the plain
70 glass panel 30 and consists of a substantially rectangular rear wall 31 and an inverted U-shaped side wall 32. The side wall is formed integrally with, and projects forwards from, the top and side margins of the rear wall 31 and has
75 at the lower ends of its side portions inwardly
