Abstract

A motherboard is secured in a chassis by a spring loaded plunger. An anchor member is mounted in the chassis. The anchor member includes a ramp and a receiver. The motherboard has an opening formed therein. A first member is secured to the motherboard. A second member is resiliently mounted on the first member so that the second member extends through the opening. The motherboard is moved on the chassis so that the second member is moved in a first direction by engaging the ramp, and the resilient mounting of the second member urges the second member in a second direction into the receiver.

Claims (62)

1. A computer chassis comprising:

a motherboard having an opening formed therein;

a first member secured to the motherboard, the first member including a base and a guide having a plurality of spaced sections;

a second member carried by the first member and extending through the opening, the second member including a receiver for receiving the guide, the receiver having at least one slot formed therein and at least one retainer extending therefrom; and

a resilient member movably interconnecting the first and second members for urging the second member through the opening.

2. The chassis as defined in claim 1 wherein the motherboard is slidably mounted in the chassis.

3. The chassis as defined in claim 2 wherein the chassis includes an anchor member.

4. The chassis as defined in claim 3 wherein the anchor member includes a ramp and a receiver.

5. The chassis as defined in claim 4 wherein in response to sliding engagement with the ramp, the second member moves relative to the first member in a first direction, and in response to alignment with the receiver the second member moves in a second direction opposite the first direction and into engagement with the receiver.

6. The chassis as defined in claim 1 wherein at least two of the sections have a radially extending stop.

7. The chassis as defined in claim 1 wherein the guide defines a tubular passage.

8. The chassis as defined in claim 1 wherein the guide extends into the motherboard.

9. The chassis as defined in claim 8 wherein the guide includes an anti-rotation member extending into the motherboard.

10. The chassis as defined in claim 1 wherein the second member includes a dowel member extending through the guide.

11. The chassis as defined in claim 1 wherein the resilient member is supported on the at least one retainer and includes an extension extending through the motherboard.

12. The chassis as defined in claim 1 wherein the first member is secured to the motherboard by soldering.

13. An information handling system comprising:

a chassis;

a microprocessor mounted in the chassis;

a storage coupled to the microprocessor;

a motherboard mounted in the chassis and having an opening formed therein;

a first member secured to the motherboard, the first member including a base and a guide having a plurality of spaced sections;

a second member carried by the first member, the second member including a receiver for receiving the guide, the receiver having a slot formed therein and a retainer extending therefrom; and

a resilient member movably interconnecting the first and second members for urging the second member through the opening.

14. The system as defined in claim 13 wherein the second member includes a dowel member extending through the guide.

15. The system as defined in claim 13 wherein the resilient member is supported on the at least one retainer and includes an extension through the motherboard.

16. A method of securing a chassis component in a computer chassis comprising:

providing a computer chassis;

mounting an anchor member in the chassis, the anchor member including a ramp and a receiver;

providing a motherboard having an opening formed therein;

securing a first member to the motherboard, the first member including a guide;

resiliently mounting a second member on the first member so that the second member extends through the opening, the second member including a receiver for receiving the guide, the receiver including a slot formed therein and a retainer extending therefrom; and

moving the motherboard on the chassis so that the second member is moved in a first direction by engaging the ramp and the resilient mounting of the second member urges the second member in a second direction into the receiver.

17. The method as defined in claim 16 wherein the securing is provided by soldering.

18. A computer system comprising:

a chassis;

an anchor member mounted in the chassis, the anchor member including a ramp and a receiver;

a motherboard movable on the chassis and having an opening formed therein;

a first member secured to the motherboard, the first member including a guide; and

a second member resiliently mounted on the first member and extending through the opening, the second member including a receiver for receiving the guide, the receiver including a slot formed therein and a retainer extending therefrom, whereby movement of the motherboard on the chassis, moves the second member in a first direction by engaging the ramp, and the resilient mounting urges the second member in a second direction into the receiver.

19. A computer system comprising:

a chassis;

a microprocessor mounted in the chassis;

a motherboard mounted in the chassis and having an opening formed therein;

a first member secured to the motherboard, the first member including a guide;

a second member carried by the first member, the second member including a receiver for receiving the guide, the receiver including a slot formed therein and a retainer extending therefrom; and

a resilient member movably interconnecting the first and second members for urging the second member through the opening.

20. A computer system comprising:

a chassis;

a microprocessor mounted in the chassis;

a motherboard mounted in the chassis and having an opening formed therein;

a first member secured to the motherboard, the first member including a guide;

a second member carried by the first member and extending through the opening, the second member including a receiver for receiving the guide, the receiver including a slot formed therein and a retainer extending therefrom; and

a resilient member movably interconnecting the first and second members for urging the second member through the opening.

21. A computer system comprising:

a chassis;

a microprocessor mounted in the chassis;

a storage coupled to the microprocessor;

an anchor member mounted in the chassis, the anchor member including a ramp and a receiver;

a motherboard movable on the chassis and having an opening formed therein;

a first member secured to the motherboard, the first member including a guide; and

a second member resiliently mounted on the first member and extending through the opening, the second member including a receiver for receiving the guide, the receiver including a slot formed therein and a retainer extending therefrom, whereby movement of the motherboard on the chassis, moves the second member in a first direction by engaging the ramp, and the resilient mounting urges the second member in a second direction into the receiver.
