Description

MOUNTING CLAMP FOR AN ANTISOL VISOR Technical Field This invention relates to anti-sun visors for motor vehicles, and in particular to a mounting bracket assembly that allows an anti-sun visor to be installed on and removed from the vehicle without the use of tools or fasteners.

Anti-sun visors for motor vehicles are usually mounted on the roof of a motor vehicle by means of a clamp and arm assembly that allows the visor blade to rotate horizontally between a storage position and a use position. Frequently, the mounting assembly also provides a vertical axis around which the visor blade can rotate between a position close to the front windshield and a position close to the driver's or passenger's side window. For example, the North American Patent No. ,031,954 discloses a mounting and assembly clamp of arm for a screen including a REF: 23015 internal clamp having a square projection flange formed in an integrated manner that is inserted into a corresponding hole in the sheet metal roof of a vehicle. An arm of the clamp is caught in the inner clamp 5, and includes a key that fits inside an arched keyhole in the internal clamp to initially lock the internal clamp in place, and subsequently limit the interval through which the screen Can you rotate around an axis? - vertical However, a tool is required to remove the screen after it has been mounted.

Summary of the Invention The present invention is a mounting for mounting an anti-sun visor to the roof of a motor vehicle. The assembly comprises a frame, an arm receiver, and a spring. The frame has an opening therethrough, at least one anchor placed around the perimeter of the opening of the frame and adapted to be coupled to the ceiling, and at least one tab of rotation stop, placed around the perimeter of the opening of the frame. The arm receiver has a top flange adapted to be inserted through the opening of the frame, a channel adapted to receive the rotation stop tab, and a bottom flange. Finally, the spring is placed between the frame and the arm receiver so that after the insertion of the upper flange of the arm receiver through the opening of the frame and the rotation of the arm receiver about a central axis, the rotation of the stop tab enters the channel and is held therein to prevent the arm receiver from being extracted directly through the opening of the frame. The arm of the anti-sun visor can be mounted to the arm receiver either before or after insertion of the arm receiver. Accordingly, an object of the present invention is to provide an assembly of the type described above, which allows to mount an anti-sun visor on and be removed from a motor vehicle without the use of tools. Another object of the present invention is to provide an assembly of the type described above that does not have a key and keyhole arrangement that limits the horizontal displacement of the anti-sun visor. These and other objects, features and advantages of the present invention will be readily apparent from the following detailed description of the best mode of carrying out the invention, when placed in connection with the accompanying drawings.

Best Way to Carry Out The Invention With reference to the drawings, the preferred embodiments of the present invention will be described. Figures 1 to 3 show an assembly 10 according to the present invention for mounting an anti-sun visor 12 to the roof 14 of a motor vehicle. The assembly comprises a frame 16, an arm receiver 18, and a coil compression spring 20. The frame 16 is preferably generally triangular, and has a generally triangular, coaxially aligned aperture 22 therethrough defined by a perimeter elevated internal 24. A lf "plurality of anti-rotation anchors 26 are placed around the perimeter 24 of the opening of the frame 22, preferably arranged with an anchor in each of the three corners of the perimeter. The anti-rotation anchors 26 are generally projected upwards from the perimeter of the opening of the frame 22, and are adapted to be coupled with a quick fitting to the edge of a corresponding triangular perforation cut through the inner metal sheet 28 of the roof of the vehicle 14. Additionally, the anchors 26 serve as means for holding an upper liner 29 in place against the inner metal sheet 28. A plurality of rotation stop tabs 30 are likewise placed around the perimeter 24 of the opening of the frame 22, preferably arranged with a stop tab in the middle part of each of the three sides of the perimeter. The rotation stop tabs 30 project towards the opening of the frame 22 to cooperate with the channels in the arm receiver 18, as described below. The arm receiver 18 has an upper flange or sheet metal latch 32, a plurality of channels 34 formed therein, and a lower flange or spring seat 36. The upper flange 32 is dimensioned and conformed closely to the opening of the frame. 22 so that it is insertable through it. Each of the channels 34 includes a tab portion 38 open through the top flange 32, a side slot portion 40, which is preferably partially defined by an intermediate flange 42, and a tongue stop portion 44. Each channel 34 is adapted to receive a corresponding rotation stop tab 30 when the upper flange 32 is inserted through the opening of the frame 22. The spring 20 is positioned between the frame 16 and the lower flange 36 of the arm receiver 18 to divert those components from each other. After manual or other insertion of the upper flange 32 of the arm receiver through the opening of the frame 22, against the force of the spring 20, the stop or rotation tabs 30 enter a receiving portion of the corresponding tongue preferably aligned 38. When the arm receiver 18 is subsequently rotated in a counterclockwise direction as will be seen below about a central axis extending generally perpendicular to the upper face of the upper flange 32, preferably about 60 ° of As the three points of the upper flange 32 are exactly offset from the corners of the opening of the frame 22, the stop tabs 30 move through the side slot portions 40 until they come into contact with the tongue stops 44. After the upward force and compresses the spring 20 is relaxed, the stop tabs 30 are pulled upwards in the stops of tab 44 and are held there against the underside of the upper flange 32 to prevent the arm receiver 18 from being extracted directly through the opening of the frame 22. However, the arm receiver can be removed from the roof of the vehicle simply by inverting the installation process, also without the help of tools. A bore 46 is provided in the arm receiver 18 to receive with an interference fit a shorter vertical arm 48 of a rotating rod of the visor 50 of the anti-sun visor 12. An irregularly shaped projection 54 placed on the upper end of the vertical arm 48 extends, when the visor arm is fully inserted in the hole 46, through a similarly shaped opening 56 and outside the upper part of the arm receiver 18. The projection 54 is preferably formed in a "D" shape. modified that has four flat sides 58 so that the arm can rotate against only the friction produced by the adjustment with the bore 46 through the 360 degrees of a complete cycle, or at least a significant portion of a complete circle, without returning to a point where the rotating rod 50 is at risk of falling out of the arm receiver 18. Within the wide range of motion, only about 90 to 120 degrees need to be allocated to allow the visor to rotate between the practical limits of the front windshield and the driver's side window or the passenger. Alternative means for retaining the arm 48 of the rotating rod 50 in bore 56 can easily be replaced by this arrangement, such as the writing described in the above US Pat. No. 5,031,954, the description of which is incorporated herein by reference. An optional backing plate 60 may be provided coupled with the anchors 26 of the frame 16 for shipping the clamp subassembly, or for adding rigidity when the frame is sub-assembled with the top liner 29 prior to installation in the vehicle. The frame 16 preassembled in this way, the arm receiver 18 and the rotating rod of the visor 5 50 can be mounted separately and installed on the visor as received by the user before joining with the frame. The support plate 60 is therefore preferably of a generally triangular shape and is formed of rigid plastic or cardboard. Typically, without ] * -. However, the support plate 60 is not necessary when the frame is installed in a vehicle to which the upper lining has already been integrated. Figure 4 shows an alternative embodiment of the apparatus 10, which is adapted to be mounted upper lining in a place not parallel to the horizontal. For this purpose, the flanges and channels of the arm receiver 18 are positioned in the anticipated angle of the upper liner so that the arm 48 of the rotating rod of the visor 50 will nevertheless roll generally vertically. This embodiment also shows a modified design of the projection 54 having only a single flattened surface 58, as well as the hidden channel 62, which is optionally provided on the rotating rod 50 through which it can run to provide electrical power to the components of the visor such as an illuminated vanity mirror. Although the best mode for carrying out the invention in detail has been described, those familiar with the technique to which this invention relates will recognize various alternative designs and embodiments for practicing the invention as defined in the following claims. It is noted that in relation to this date, l < . The best method known by the applicant to carry out said invention is the conventional one for the manufacture of the objects referred to therein. Having described the invention as above, property is claimed as contained in the following:
