Abstract

A flexible door latch seal is disclosed for containing noise which emanates through door latches and machine covers. Noise is always a problem to contain when it emanates through cracks and openings between mechanical door latch handles and machine covers. Magnetic contact latches may solve this problem, but a mechanical latch provides a more positive latch force against the resisting force of seal strips in acoustical cover door joints. Fig. 1 represents a bottom view of a flexible door latch seal 10 of the present invention. Fig. 2 illustrates a front view of a cross section of the door latch seal 10 taken along section lines A-A of Fig. 1. Fig. 3 illustrates a left side view of the door latch seal 10. Fig. 4 illustrates a front view of the door latch seal 10 as in Fig.

Flexible Door Latch Seal

A flexible door latch seal is disclosed for containing noise which emanates through door latches and machine covers. Noise is always a problem to contain when it emanates through cracks and openings between mechanical door latch handles and machine covers. Magnetic contact latches may solve this problem, but a mechanical latch provides a more positive latch force against the resisting force of seal strips in acoustical cover door joints. Fig. 1 represents a bottom view of a flexible door latch seal 10 of the present invention. Fig. 2 illustrates a front view of a cross section of the door latch seal 10 taken along section lines A- A of Fig. 1. Fig. 3 illustrates a left side view of the door latch seal 10. Fig. 4 illustrates a front view of the door latch seal 10 as in Fig. 2 but including a door latch handle 12 inserted therein. Referring to Figs. 1-4, a flexible seal 10 consists essentially of an elastomer molding. It is fitted over a door latch handle 12, as in Fig. 4. The "cavity" shape of the molding includes a perimeter flange 14 (Fig. 4) which is fastened and sealed at the perimeter 16 of a cover door opening 18 using a known mechanical or adhesive bonding technique. An alternate method of fastening is shown which utilizes the stretch and resilient properties of the elastomer. With the seal installed, the door latch is activated by inserting fingers into the cavity and pulling on the door latch handle 12 in a conventional manner. In...
