Abstract

An assembly that includes first and second housing members, a gasket and a plurality of bolts that exert a clamp force to clamp the gasket between the first and second housing members. The gasket includes a plurality of tab members that engage the interior of one or both of the first and second housing members. The gasket tabs can resist a force exerted by a pressurized fluid within one or both of the first and second housing members. A method for assembling and operating an article is also provided.

Claims

1. An assembly comprising:

a housing assembly having a housing and a nosepiece;

a driver received in the nosepiece;

a motor assembly disposed in the housing assembly, the motor assembly being coupled to the driver and being operable for translating the driver in a driving direction;

a trigger coupled to the housing assembly and operable for selectively activating the motor assembly to translate the driver; and

a magazine assembly coupled to the housing assembly, the magazine assembly being adapted to store a plurality of fasteners and sequentially feed the fasteners into the nosepiece;

wherein the housing includes a first housing member, a second housing member and a gasket, the first housing member including a first inner surface, a first outer surface, and a first end face, wherein the first inner surface at least partly defines a first cavity, and wherein the first end face extends between the first inner surface and the first outer surface, the second housing member including a second inner surface, a second outer surface, and a second end face, wherein the second inner surface at least partly defines a second cavity, and wherein the second end face extends between the second inner surface and the second outer surface, the gasket being received axially between the first and second housing members and sealingly engaging the first and second end faces, the gasket including a plurality of gasket bosses and including at least one projecting portion that is located between two consecutive ones of the plurality of gasket bosses, wherein the at least one projecting portion extends into the first and second cavities, wherein the at least one projecting portion contacts the first and second inner surfaces, and wherein the at least one projecting portion is configured to limit laterally outward movement of the gasket between the first and second end faces relative to the first and second housing members; and

wherein the at least one projecting portion is preformed prior to compression of the gasket between the first and second housing members.

2. The assembly of claim 1, wherein the gasket is at least partially formed of an elastomer.

3. The assembly of claim 2, wherein the elastomer is a thermoplastic elastomer.

4. The assembly of claim 1, wherein the housing further comprises a plurality of bolts that apply a clamp force to the first housing member, the gasket and the second housing member.

5. The assembly of claim 4, wherein the at least one projection is disposed in a region in which a magnitude of the clamp force transmitted through the first housing member, the gasket and the second housing member is relatively lower than surrounding regions.

6. The assembly of claim 1 wherein the at least one projecting portion extends perpendicular to the first and second end faces.

7. An assembly comprising:

a housing assembly having a housing and a nosepiece;

a driver received in the nosepiece;

a motor assembly disposed in the housing assembly, the motor assembly being coupled to the driver and being operable for translating the driver in a driving direction;

a trigger coupled to the housing assembly and operable for selectively activating the motor assembly to translate the driver; and

a magazine assembly coupled to the housing assembly, the magazine assembly being adapted to store a plurality of fasteners and sequentially feed the fasteners into the nosepiece;

wherein the housing includes a first housing member, a second housing member and a gasket, the first housing member including a first inner surface, a first outer surface, and a first end face, wherein the first inner surface at least partly defines a first cavity, and wherein the first end face is disposed between the first inner surface and the first outer surface, the second housing member including a second inner surface, a second outer surface, and a second end face, wherein the second inner surface at least partly defines a second cavity, and wherein the second end face is disposed between the second inner surface and the second outer surface, the gasket being received axially between the first and second housing members and sealingly engaging the first and second end faces, the at least one projecting portion being configured to limit outward movement of the gasket between the first and second end faces relative to the first and second housing members;

wherein each of the at least one projecting portions is received into a corresponding recess that is formed in the midst of first end face, the second end face or both the first and second end faces, and

wherein the at least one projecting portion is preformed prior to compression of the gasket between the first and second housing members.

8. The assembly of claim 7, wherein the gasket is at least partially formed of an elastomer.

9. The assembly of claim 8, wherein the elastomer is a thermoplastic elastomer.

10. The assembly of claim 7, wherein the housing further comprises a plurality of bolts that apply a clamp force to the first housing member, the gasket and the second housing member.

11. The assembly of claim 10, wherein the at least one projection is disposed in a region in which a magnitude of the clamp force transmitted through the first housing member, the gasket and the second housing member is relatively lower than surrounding regions.

12. The assembly of claim 7, wherein each corresponding recess is disposed in the middle of the first end face, the middle of the second end face or in the middle of the first end face and the middle of the second end face.

13. An assembly comprising:

a housing assembly having a housing and a nosepiece;

a driver received in the nosepiece;

a motor assembly disposed in the housing assembly, the motor assembly being coupled to the driver and being operable for translating the driver in a driving direction;

a trigger coupled to the housing assembly and operable for selectively activating the motor assembly to translate the driver; and

a magazine assembly coupled to the housing assembly, the magazine assembly being adapted to store a plurality of fasteners and sequentially feed the fasteners into the nosepiece;

wherein the housing includes a first housing member, a second housing member and a gasket, the first housing member including a first inner surface, a first outer surface, and a first end face, wherein the first inner surface defines a first cavity, and wherein the first inner and outer surfaces define the first end face, the second housing member including a second inner surface, a second outer surface, and a second end face, wherein the second inner surface defines a second cavity, and wherein the second inner and outer surfaces define the second end face, the gasket being received axially between the first and second housing members and sealingly engaging the first and second end faces, the gasket including at least one gasket tab that extends perpendicular to the first and second end faces and into the first and second cavities, the at least one gasket tab limiting laterally outward movement of the gasket between the first and second end faces relative to the first and second housing members;

wherein the at least one gasket tab is preformed prior to compression of the gasket between the first and second housing members.

14. The assembly of claim 13, wherein the housing further comprises a plurality of bolts that apply a clamp force to the first housing member, the gasket and the second housing member, and wherein the at least one gasket tab is located between two consecutive ones of the plurality of bolts.

15. The assembly of claim 13, wherein the gasket is at least partially formed of an elastomer.
