Description

MOUNTING BRACKET FOR A SUN V SOR

Technical Field

This invention relates to sun visors for motor vehicles, and in particular to a mounting bracket assembly that allows a sun visor to be installed in and removed from the vehicle without the use of tools or fasteners .

Background Art

Sun visors for motor vehicles are normally mounted to the roof of a motor vehicle by a bracket and arm assembly that allows the visor blade to pivot horizontally between a storage and a use position. Often, the mounting assembly also provides a vertical axis about which the visor blade may pivot between a position proximate the front windshield and a position proximate the driver's side or passenger's side window.

For example, U.S. Patent No. 5,031,954 discloses a mounting bracket and arm assembly for a sunshade including an inner bracket having an integrally formed square boss that is inserted into a corresponding hole in the sheet metal roof of a vehicle . A bracket arm is snapped into the inner bracket, and includes a key that fits within an arcuate keyway in the inner bracket to initially lock the inner bracket in place, and thereafter limit the range through which the sunshade may pivot about a vertical axis. However, a tool is required to remove the sunshade after it has been mounted.

Summary Of The Invention

The present invention is a fastener for mounting a member such as a sun visor pivot arm to a wall such as the roof of a motor vehicle. The fastener comprises a frame, a receiver, a torque key and an arm. The frame has an opening and at least one leg disposed proximate the opening. The receiver has a projection and a pocket in which the torque key is disposable. The arm is connected to the member and includes a band shaped to engage a hole in the torque key. In a first position, the torque key hole engages the band such that rotation of the arm causes the receiver projection to engage the frame leg. In a second position, the torque key hole does not engage the band.

In an alternate embodiment, the frame has at least one frame slot disposed in the leg, the receiver has at least one passage, and the torque key has at least one interlock tang which is movable through the receiver passage. In a first position, the arm extends through the torque key hole, the receiver and the frame opening, and the band engages the torque key hole such that rotation of the arm causes the receiver projection to engage the frame leg and the interlock tang to align with the frame slot. In a second position, the arm extends through the torque key hole, the receiver and the frame opening, and the band does not engage the torque key hole while the interlock tang engages the frame slot such that the torque key, the receiver and the frame are locked together.

Accordingly, it is an object of the present invention to provide a fastener of the type described above which allows a sun visor to be mounted in and removed from a motor vehicle without the use of tools.

Another object of the present invention is to provide a fastener of the type described above that does not have a key and keyway arrangement limiting the horizontal sweep of the sun visor.

It is yet another object of the present invention to provide a fastener of the type described above that cannot become inadvertently disassembled.

These and other objects, features, and advantages of the present invention are readily apparent from the following detailed description of the best mode for carrying out the invention when taken in connection with the accompanying drawings .

Best Mode For Carrying Out The Invention

With reference to the drawings, the preferred embodiments of the present invention will be described. Figures 1 through 3 show a fastener 10 according to the present invention for fastening a sun visor 12 to the inner sheet metal roof 14 of a motor vehicle. The assembly comprises a frame 16, an arm receiver 18 and a torque key 20.

The frame 16 is preferably generally circular, and has a coaxially aligned, preferably generally round opening 22 therethrough. A plurality of closely spaced legs 24 are disposed proximate the opening 22, and are movable from an initial insertion position shown in Figure 3 to an operational position shown in Figure 2 to lock the frame 16 against the sheet metal 14. A plurality of anti-rotation retainer tabs 26 disposed around the perimeter of the frame 16 project generally upwardly, and are adapted to snap fit into a series of matching holes cut through the sheet metal 1 .

The arm receiver 18 has a projection 28, a pocket 30, and a pair of molded-in springs 32 disposed in the pocket. The projection 28 extends from the upper surface of the arm receiver, and includes a preferably square boss 34 sized and shaped closely to the frame opening 22 so as to just be insertable through a generally matching shape defined by interior portions 35 of the frame legs 24. The pocket 30 preferably has a generally oval shape, and is formed as a recess on the lower surface of the arm receiver 18.

The torque key 20 is also preferably formed with an oval periphery, but it should be appreciated that the torque key may have any shape in which at least a portion of the periphery is adapted to non-rotationally mate with the border of the pocket 30 when the torque key is disposed in the pocket. Likewise, the torque key 20 includes an axially splined hole 36 for non- rotational engagement with a splined, circumferential band 38 formed on an end 40 of a pivot arm 42 of the sun visor 12. It should be appreciated that the springs 32 may be incorporated on the upper surface of the torque key instead of on the lower surface of the receiver 18, or provided separately from either the torque key or the receiver.

To assemble the fastener 10, the torque key 20 and receiver 18 are fit over the end 40 of the visor pivot arm until resilient, displacable fingers 44 on the distal end of the projection 28 snap back to trap ball 46 on the end of the pivot arm. The end 40 of the pivot arm is then manually or otherwise inserted into the frame 16, with the square boss 34 aligned with the opening defined by the interior leg portions 35.

Next, the torque key 20 is depressed against the bias of the springs 30 to engage the torque key splines 36 with the visor arm splines 38. When the pivot arm 42 is thereafter rotated either clockwise or counterclockwise, the torque key 20 and the receiver 18 similarly rotate and the boss 34 radially deflects the frame legs 24 against the back side of the sheet metal 14. Because the pivot arm 42 acts as a lever to facilitate this procedure, only a minimal effort is required.

After the receiver 18 rotates about 45 degrees, the corners of the square boss 34 are aligned with notches 48 formed in adjacent pairs of the legs 24. The bias of the legs 24 draws the legs snugly against the corners of the boss and, because the dimensions of the square defined by the notches 48 are on the order of 1 millimeter smaller than the sides of the boss 34, the legs 24 are held at a slight angle over the sheet metal to prevent the direct withdrawal of any of the components .

The upward force compressing the torque key 20 against the springs 32 is then relaxed, which allows the boss 34 to assume an operational position holding the frame legs 24 apart. At the same time, the springs 32 bias the torque key 20 away from the circumferential band 38 and against a circumferential stop 50 on the end 40 of the visor arm. The torque key 20 remains within the pocket 30, but the torque key hole 36 generally faces a clearance channel 52 formed on the pivot arm end 40 just below the band 38. Because there is little or no interference between the torque key 20 and the channel 52, the visor arm 42 is free to rotate about the visor pivot axis in a conventional manner.

The boss 34 is held in the operational position to prevent the arm receiver 18 from being withdrawn directly through the frame opening 22. However, the arm receiver can be removed from the roof of the vehicle by simply depressing the torque key 20 against the springs 32 and reversing the installation process, again without the aid of tools. This result is similar to that accomplished by the mounting bracket disclosed in U.S. Patent No. 5,451,022, assigned to the assignee of the present invention and hereby incorporated by reference.

Figures 4 and 5 show an alternative embodiment 100 of the fastener for mounting the sun visor 12 to the roof 14 of the vehicle. The fastener 100 includes a frame 102 and a receiver 104. The frame 102 has a generally circular opening 106, a plurality of legs 108 circumferentially disposed proximate the opening, and a series of inwardly projecting lifter pegs 110. The legs 108 are inwardly flexible but pre-stressed so as to be normally biased radially outwardly from the opening 106, and include sloped faces 112 to facilitate insertion of the legs through a center circular hole in the sheet metal 14. Like the fastener 10, a plurality of anti- rotation retainer tabs 114 disposed around the perimeter of the frame 102 project generally upwardly, and are adapted to snap fit into a series of matching holes cut through the sheet metal 14.

The receiver 104 is preassembled on a visor pivot arm 116, which in turn is connected to the visor 12 by any conventional method. The receiver 104 has a generally circular base 118, a frusto-conical projection 120 extending upwardly from the base, and preferably four downwardly sloping tracks 122 evenly spaced around the outside of the base. After the frame 102 has been installed, the tracks 122 are adapted to engage corresponding lifter pegs 110 when the receiver 104 is brought next to the frame. Upon subsequent rotation of the receiver, the pegs 110 ride deeper into the tracks 122, and draw the receiver projection 120 toward the sheet metal and into the frame opening 106 to radially displace the frame legs 108.

After a predetermined amount of rotation, preferably 45 degrees, the pegs 110 reach the ends of the tracks 122 and the projection 120 is at the point of maximum penetration. At this point, flanges 124 on the legs 108 retract to engage a snap ring groove 126 formed in the projection 120, locking the visor 12 to the frame 102 and the sheet metal roof.

Subsequent to installation, the visor pivot arm 116 is free to rotate 360 degrees in either the clockwise or counterclockwise direction. To remove the fastener 100, a pre-situated service key 128 may be wedged up into a keyway 130 formed in the pivot arm 116 to rotationally lock the arm relative to the receiver 104.

Figures 6 through 8 show another alternative embodiment 210 of the fastener for mounting the sun visor 12 to the inner sheet metal roof 14 of a motor vehicle. The assembly comprises a frame 216, an arm receiver 218 and a torque key 220.

The frame 216 is preferably generally circular, and has a coaxially aligned, preferably generally round opening 222 therethrough. A plurality of closely spaced movable legs 224 are disposed proximate the opening 222. The legs 224 include sloped faces 226 to facilitate insertion of the legs through a circular hole in the sheet metal 14. Alternating legs 224' are provided with a grooved extension 228 and a generally vertical frame slot 230. A plurality of anti-rotation retainer tabs 232 disposed around the perimeter of the frame 216 project generally upwardly, and are adapted to snap fit into a series of matching holes cut through the sheet metal 14.

The arm receiver 218 has a projection 234, a plurality of passages 236 disposed in the projection, a pocket 238, and a pair of molded-in springs 240 disposed in the pocket. The projection 234 extends from the upper surface of the arm receiver, and includes a plurality of threaded extensions 242 sized and shaped to engage the grooved extensions 228 on the alternating frame legs 224'. Threaded extension as used herein means a member extending from the projection 234 and including one or more helical or spiral ridges. Alternative means of engaging the receiver projection 234 with the frame 216 may be used, such as a groove and peg arrangement or any other means understood by those skilled in the art. The pocket 238 preferably has a generally circular shape, and is formed as a recess on the lower surface of the arm receiver 218.

The torque key 220 is also preferably formed with a circular periphery. The torque key 220 includes an axially splined hole 244 for non-rotational engagement with a splined, circumferential band 246 formed on an end 248 of a pivot arm 250 of the sun visor 12. The torque key is also provided with a plurality of interlock tangs 252 which are insertable through the receiver passages 236. It should be appreciated that the springs 240 may be incorporated on the upper surface of the torque key instead of on the lower surface of the receiver 218, or provided separately from either the torque key or the receiver. To assemble the fastener 210, the torque key 220 is inserted into the receiver 218 by biasing the interlock tangs 252 inwardly so that they are movable through the receiver passages 236. The torque key 220 is inserted into the receiver until horizontal portions 253 of the interlock tangs 252 snap back to their original position and above the threaded extensions 242. Alternatively, interlock tangs without the horizontal portions may be completely inserted through the receiver passages 236 without forcing the tangs inwardly, and then the horizontal portions 253 of the tangs may be attached to the vertical portions of the tangs by any known method such that they extend over the extensions 242.

The torque key 220 and receiver 218 are then fit over the end 248 of the visor pivot arm and a fitting, such as a conventional snap ring 258 as shown in Figures 7 and 8, is placed over the end of the pivot arm to secure the pivot arm to the receiver. A spring, such as a spring washer 260, may be placed between the snap ring 258 and the receiver 218 to ensure a close fit between the receiver 218 and the pivot arm 250. Alternatively, the receiver 218 may be secured to the pivot arm 250 in a manner similar to that described with respect to the embodiment shown in Figures 2-3, or by any other means as understood by those skilled in the art. The projection 234 may extend further from the upper surface of the receiver 218 than shown, in order to eliminate potential interference between the snap ring 258, or other fitting, and the interlock tangs 252. The end 248 of the pivot arm is then manually or otherwise inserted into the frame 216, with the threaded extensions 242 of the receiver 218 aligned with the opening defined by the interior leg portions 243 of the frame 216. Next, the torque key 220 is depressed against the bias of the springs 240 to engage the torque key splines 244 with the splined, circumferential band 246 and to raise the horizontal portions 253 of the interlock tangs 252 above the frame 216. When the pivot arm 250 is thereafter rotated clockwise, the torque key 220 and the receiver 218 similarly rotate and the threaded extensions 242 radially deflect the frame legs 224' against the back side of the sheet metal 14. Because the pivot arm 250 acts as a lever to facilitate this procedure, only a minimal effort is required.

After the receiver 218 rotates about 45 degrees, the threaded extensions 242 are aligned with the mating grooved extensions 228 of the frame legs 224' and the interlock tangs 252 are aligned with the frame slots 230 as shown in Figure 7. The bias of the legs 224' draws the legs closely against the threaded extensions 242 and, because the diameter of the opening defined by the frame legs 224' with grooved extensions 228 is on the order of 1 millimeter smaller than the diameter of the projection 234 including the threaded extensions 242, the legs 224' are held at a slight angle over the sheet metal to prevent the direct withdrawal of any of the components .

The upward force compressing the torque key 220 against the springs 240 is then relaxed, which allows the interlock tangs 252 to assume an operational position engaging the frame slots 230, such that the torque key 220, the receiver 218 and the frame 216 are locked together as shown in Figure 8. At the same time, the springs 240 bias the torque key 220 away from the circumferential band 246 and against a circumferential stop 254 on the end 248 of the visor pivot arm. The torque key 220 remains within the pocket 238, but the torque key hole 244 generally faces a clearance channel 256 formed on the pivot arm end 248 just below the band 246. Because there is little or no interference between the torque key 220 and the channel 256, the visor arm 250 is free to rotate about the visor pivot axis in a conventional manner.

The torque key 220, the receiver 218 and the frame 216 are locked together in the operational position by the interlock tangs 252 to prevent the arm receiver 218 from being withdrawn directly through the frame opening 222. However, the arm receiver can be removed from the roof of the vehicle by simply depressing the torque key 220 against the springs 240 and reversing the installation process, again without the aid of tools.

Figures 9 and 10 show another alternative embodiment 310 of the fastener for mounting the sun visor 12 to the roof 14 of the vehicle. Fastener 310 includes a frame 316, a receiver 318 and a torque key 320. The frame 316 is of sheet metal construction and is made by preforming the sheet metal roof 14 of the motor vehicle. The frame 316 preferably has a generally round opening 322 therethrough. A plurality of spaced apart legs 324 are disposed proximate the opening 322 and each leg has a generally vertical frame slot 326.

The arm receiver 318 has a projection 328, a plurality of passages 332, a pocket 334 and a pair of molded-in springs 336 disposed in the pocket. The projection 328 extends from the upper surface of the arm receiver, and includes a plurality of extensions 338. Each extension has a sloped groove 340 disposed therein to engage one of the frame legs 324. The pocket 334 preferably has a generally circular shape, and is formed as a recess on the lower surface of the arm receiver 318.

The torque key 320 is also preferably formed with a circular periphery. The torque key 320 includes an axially splined hole 342 for non-rotational engagement with a splined, circumferential band 344 formed on an end 346 of a pivot arm 348 of the sun visor 12. The torque key also includes a plurality of interlock tangs 350 which are insertable through the receiver passages 332. It should be appreciated that the springs 336 may be incorporated on the upper surface of the torque key 320 instead of on the lower surface of the receiver 318, or provided separately from either the torque key or the receiver.

To assemble the fastener 310, the torque key 320 is inserted into the receiver 318 by biasing the interlock tangs 350 inwardly so that they are movable through the receiver passages 332. The torque key 320 is inserted into the receiver until horizontal portions 351 of the interlock tangs 350 snap back to their original position and above the sloped grooves 340. Alternatively, interlock tangs without the horizontal portions may be completely inserted through the receiver passages 332 without forcing the tangs inwardly, and then the horizontal portions 351 of the tangs may be attached to the vertical portions of the tangs by any known method such that they extend over the sloped groves 340. The torque key 320 and receiver 318 are then fit over the end 346 of the visor pivot arm and a fitting, such as a conventional snap ring 352 as shown in Figure 10, is placed over the end of the pivot arm to secure the pivot arm to the receiver 318. A spring, such as a spring washer 354, may be laced between the snap ring 352 and the receiver 318 to ensure a snug fit between the receiver 318 and the pivot arm 348. Alternatively, the receiver 318 may be secured to the pivot arm 348 in a manner similar to that described with respect to the embodiment shown in Figures 2-3, or by any other means as understood by those skilled in the art. The projection 328 may extend further from the upper surface of the receiver 318 than shown, in order to eliminate potential interference between the snap ring 352, or other fitting, and the interlock tangs 350. The end 346 of the pivot arm is then manually or otherwise inserted into the frame 316, with the extensions 338 aligned with the spaces between the legs 324.

Next, the torque key 320 is depressed against the bias of the springs 336 to engage the torque key splines 342 with the splined, circumferential band 344 and to raise the horizontal portions 351 of the interlock tangs 350 above the frame 316. When the pivot arm 348 is thereafter rotated clockwise, the torque key 320 and the receiver 318 similarly rotate and the sloped grooves 340 engage the frame legs 324. Since the grooves 340 are sloped downward, rotation of the torque key 320 and the receiver 318 about the frame legs 324 draws the receiver 318 closely against the frame 316. After the torque key 320 and the receiver 318 rotate about 45°, the interlock tangs 350 are aligned with the frame slots 326. The upward force compressing the torque key 320 against the springs 336 is then relaxed, which allows the interlock tangs 350 to assume an operational position engaging the frame slots 326, such that the torque key 320, the receiver 318 and the frame 316 are locked together as shown in Figure 10. At the same time, the springs 336 bias the torque key 320 away from the circumferential band 344 and against a circumferential stop 354 on the end 346 of the visor pivot arm. The torque key 320 remains within the pocket 334, but the torque key hole 342 generally faces a clearance channel 356 formed on the pivot arm end 346 just below the band 344. Because there is little or no interference between the torque key 320 and the channel 356, the visor arm 348 is free to rotate about the visor pivot axis in a conventional manner.

The torque key 320, the receiver 318 and the frame 316 are locked together in the operational position by the interlock tangs 350 to prevent the arm receiver 318 from being withdrawn directly through the frame opening 322. However, the arm receiver can be removed from the roof of the vehicle by simply depressing the torque key 320 against the springs 336 and reversing the installation process, again without the aid of tools.
