Abstract

A fan receiver assembly (1200) includes a fan receiver (101). The fan receiver includes a rear wall (128) and at least one sidewall (112). At least one deformable clasp (105) is coupled to, and translatable along, the sidewall. The deformable clasp includes at least one latching arm (142) that is pivotable between an axially displaced open position occurring when the latching arm extends beyond a terminal end sidewall and a parallel position occurring when the latching arm is situated between the terminal end and the rear wall. The sidewall defines a d-track (111) having a terminal end (125) and an outward notch (126). A follower situates within the d-track between the deformable clasp and the sidewall. A fan module (102) latches to the fan receiver assembly when the follower situates within the outward notch.

First claim

What is claimed is:

1. A fan receiver assembly, comprising:
a fan receiver comprising a rear wall and at least one sidewall; and
at least one deformable clasp coupled to, and translatable along, the at least one sidewall, and one or more coiled springs biasing the at least one deformable clasp away from the sidewall, the at least one deformable clasp comprising at least one latching arm pivotable relative to the at least one deformable clasp between an axially displaced open position occurring when the at least one latching arm extends beyond a terminal end of the at least one sidewall and a parallel position occurring when the at least one latching arm is situated between the terminal end and the rear wall, where the at least one sidewall defines a d-track comprising a terminal end and an outward notch, further comprising a follower situated within the d-track between the at least one deformable clasp and the at least one sidewall.

2. The fan receiver assembly of claim 1 , the at least one latching arm comprising a living hinge, the at least one latching arm pivotable between the axially displaced open position and the parallel position about the living hinge.

3. The fan receiver assembly of claim 1 , the at least one deformable clasp defining a blind slot, further comprising a flat spring situated in the blind slot and biasing the follower into the d-track.

4. The fan receiver assembly of claim 3 , the terminal end and the outward notch defining stoppage stations for the follower when the at least one latching arm pivotable is in the axially displaced open position and the parallel position, respectively.

5. The fan receiver assembly of claim 1 , the at least one latching arm pivoting to the axially displaced open position when the follower situates in the terminal end, and pivoting to the parallel position when the follower situated in the outward notch.

6. The fan receiver assembly of claim 3 , the at least one sidewall comprising a pair of oppositely facing L-shaped rails defining a translation slot, the at least one deformable clasp comprising wings situated in, and translatable along, the translation slot.

7. The fan receiver assembly of claim 6 , the at least one deformable clasp comprising one or more L-shaped feet extending distally from the at least one deformable clasp in a direction opposite that of the at least one latching arm.

8. The fan receiver assembly of claim 6 , further comprising at least one deformable clasp deformer/retainer retaining the wings of the at least one deformable clasp within the translation slot.

9. The fan receiver assembly of claim 8 , the at least one deformable clasp deformer/retainer defining one or more recesses, the at least one sidewall comprising one or more snap fit protrusions situated within the one or more recesses.

10. The fan receiver assembly of claim 9 , the at least one deformable clasp deformer/retainer comprising at least one arm deformer causing the at least one latching arm the at least one deformable clasp to pivot from the axially displaced open position to the parallel position when the wings translate within the translation slot toward the rear wall.

11. The fan receiver assembly of claim 10 , further comprising one or more bosses extending distally from the rear wall from a base at the rear wall a distal end defining an inward taper.

12. A method of assembling a fan receiver assembly, the method comprising:
providing a fan receiver comprising a first sidewall, a second sidewall, and a rear wall interspacing the first sidewall and the second sidewall, each of the first sidewall and the second sidewall comprising:
a raised platform and a d-track recessed into the raised platform; and
a pair of L-shaped rails defining a translation slot;

placing one or more coiled springs into a cavity defined by the rear wall, the first sidewall, and the second sidewall;
placing a first follower and a first flat spring a blind slot of a first deformable clasp and a second follower and second flat spring another blind slot of a second deformable clasp; and
coupling the first deformable clasp and the second deformable clasp to the fan receiver by inserting wings of the first deformable clasp into the translation slot of the first sidewall and wings of the second deformable clasp in the translation slot of the second sidewall, thereby causing the first follower to be biased in the d-track of the raised platform of the first sidewall and the second follower to be biased in the d-track of the raised platform of the second sidewall.

13. The method of claim 12 , further comprising coupling a first deformable clasp deformer/retainer to the first sidewall and a second deformable clasp deformer/retainer to the second sidewall by passing recesses defined in the rear sides of the first deformable clasp deformer/retainer and the second deformable clasp deformer/retainer over snap fit protrusions disposed along interiors of the first sidewall and the second sidewall.

14. The method of claim 13 , further comprising coupling one or more spring-biased electrical connectors to the rear wall.

15. A fan receiver assembly, comprising:
a rear wall, a first sidewall extending distally from a first end the rear wall, and a second sidewall extending distally from a second, opposite end of the rear wall;
a first deformable clasp coupled to, and translatable along, the first sidewall;
a second deformable clasp coupled to, and translatable along, the second sidewall;
one or more coiled springs biasing the first deformable clasp away from the rear wall;
one or more other coiled springs biasing the second deformable clasp away from the rear wall;
one or more spring-biased electrical connectors coupled to the rear wall; and
a fan module, latched to the fan receiver assembly, and comprising one or more complementary electrical connectors;

the first deformable clasp and the second deformable clasp each comprising one or more latching arms pivotable between an axially displaced open position when the one or more latching arms extend beyond terminal ends of the first sidewall and the second sidewall and a parallel position when the one or more latching arms are situated between the first side wall and the second sidewall.

16. The fan receiver assembly of claim 15 , each of the first sidewall and the second sidewall comprising a d-track comprising a terminal end and an outward notch, further comprising a first follower biased from the first deformable latch into the d-track of the first sidewall and a second follower biased from the second deformable latch into the d-track of the second sidewall.

17. The fan receiver assembly of claim 16 , the one or more latching arms each comprising at least one latch and at least one L-shaped foot latching the fan module to the fan receiver assembly when the first follower and the second follower situate within the outward notch of the d-track of the first sidewall and the second sidewall, respectively, with the one or more complementary electrical connectors electrically coupled to the one or more spring-biased electrical connectors.
