DETAILED DESCRIPTION
(47) While the light module fastener assembly may be susceptible to embodiment in different forms, there are shown in the drawings, and herein will be described in detail, certain illustrative embodiments with the understanding that the present disclosure is to be considered an exemplification of the principles of the light module fastener assembly, and is not intended to limit the light module fastener assembly to those as illustrated and described herein. Additionally, features illustrated and described with respect to one embodiment could be used in connection with other embodiments.
(48) Referring to
(49) Referring to
(50) Each fastening assembly 18 includes a carrier receptacle 20 formed in or otherwise secured to the carrier bracket 16, wherein each carrier receptacle 20 is engaged with a respective snap wedge assembly that in turn is securable to the light module 14. The snap wedge assemblies can include both adjustable snap wedge assemblies 22 (securable to carrier receptacle 20) and non-adjustable snap wedge assemblies 22(securable to carrier receptacle 20), as discussed in detail below. Adjustable snap wedge assemblies 22 can be used to allow horizontal and vertical aiming for the light module 14, while non-adjustable snap wedge assemblies 22 can provide fixed length pivotable securement for the light module 14 where needed. For example, when secured to a light module 14 the snap wedge assembly 22 further identified with the letter H in
(51) Referring now to
(52) In at least some embodiments, the ball stud 32 includes a terminal end 60 and a ball end 62, wherein the ball end 62 is configured to interlock with a mating portion of the light module 14 to pivotably secure the light module 14 to the carrier bracket 16, and the terminal end 60, as well as the ball end 62, can include indentations or protrusions configured to engage an adjustment tool for rotating the ball stud 32 to perform an aiming adjustment for the light module 14. The ball end 62 can vary in size and shape to accommodate coupling to the light module 14.
(53) As noted above, the snap wedge assembly 22 is secured to the carrier bracket 16 by engagement with the carrier receptacles 20. Further referring to
(54) It is desirable for the snap wedge assembly 22 to be pushed into the carrier receptacle 20 without undue concern for over-insertion, which can comprise the security and functionality of the fastening assembly 18. In this regard, in addition to rotational securement, a wedge top surface 52 serves to prevent the insert 30 from being inserted into the receptacle passage 70 beyond a desired point, as the wedge top surface 52 fully abuts with the complementary top pocket wall 75, the insert 30 ceases to move further through the receptacle passage 70. In at least some embodiments, a wedge ledge 77 can also be utilized to provide an insertion limitation, wherein the wedge ledge 77 is formed on the wedge 50 and abuts a complementary passage stop wall 80 formed in the receptacle passage 70. The passage stop wall 80 extends, in at least some embodiments, substantially perpendicular to the top pocket wall 75 to provide a positive stop.
(55) In addition to addressing the desire for an insertion limit, it is also desirable to secure the insert 30 to the carrier receptacle 20 once installed therein. In at least some embodiments, this is accomplished via the snap fingers 42, which flex inwards against a bias when inserted through the receptacle passage 70, and flex outwards once the latching portions 46 have exited the receptacle passage 70. The latching portions 46 are then in abutment or in position to abut with a receptacle rear wall 78 (see also
(56) The wedge ledge 77 and the complementary passage stop wall 80 can be omitted from the fastening assembly 18 in at least some embodiments, as seen in
(57) Referring now to
(58) As shown in
(59) In certain applications it may be desirable to include lugs, tabs, or other protrusions on the insert 30 that engage complementary slots or grooves in the receptacle passage 70 so as to force a particular installation orientation or as a substitute means of providing anti-rotation securement. While the embodiments illustrated in
(60) Referring to
(61) As shown in
(62) The insert 98 further includes a rear wall 99 and front wall 101, as well as a plurality of snap fingers 120 each having an elongated flexible portion 122 and a latching portion 124. As discussed above, the snap fingers flex inwards when inserted into the receptacle passage 94 in an insert direction 95, and flex outwards when exiting the receptacle passage 94, to provide abutment of the latching portions 124 against a rear wall 126 of the carrier receptacle 90. In this manner the snap wedge assembly 92 can be laterally secured in the carrier bracket 16 and aiming adjustments can be made.
(63) While various embodiments illustrated in
(64) A fastener assembly 129 that includes a non-adjustable snap wedge assembly 150 is illustrated in
(65) This invention relates primarily to adjusters and mounts for LED light modules used in vehicle headlamps. It may also be used in other applications where similar performance characteristics are desired and the description herein of the invention used in automotive headlamps should not been interpreted as limiting use to such an environment. It is specifically intended that the fastener assembly not be limited to the specific embodiments and illustrations contained herein, but include modified forms of those embodiments including portions of the embodiments and combinations of elements of different embodiments as come within the scope of the following claims. Accordingly, the foregoing description is meant to be exemplary only, the invention is to be taken as including all reasonable equivalents to the subject matter of the invention, and should not limit the scope of the invention set forth in the following claims. The use of the term plurality is intended to include one or more.
