Abstract

A blower motor mounted in a housing with the use of two end supports which act as shock absorbers and positioning devices. Each end support is formed of relatively soft flexible material and comprises a cup shaped member adapted to be attached to an end of the motor. Extending radially outward from the cup shaped member are a plurality of spaced apart legs adapted to engage the wall of the housing. Each leg comprises two spaced apart leg members which diverge outward from each other and a flexible arcuate bridge portion connecting the outer ends of the leg members for engaging the wall of the housing.

Claims

1. A blower assembly comprising:

a. a blower housing having a longitudinal axis and made up of a top section and a bottom section which fit together generally in a plane parallel to said longitudinal axis;

b. a motor having shaft portions extending from opposite ends thereof, with a blower attached to each shaft portion, and a motor housing having a generally cylindrical portion coaxial with said shaft portions and end walls integral with the cylindrical portion and disposed generally transversely of said shaft portions;

c. an end support attached to each end wall of said motor housing for supporting said motor and blowers in said blower housing, each end support comprising;

i. a body portion having a generally cylindrical portion disposed coaxially with a respective said motor shaft portion and an end wall disposed generally transversely of said motor shaft portion,

ii. said body portion further having a concavity formed by interior surfaces of said cylindrical portion and said respective end wall, with said concavity shaped to conformingly fit the corresponding cylindrical portions and end walls of said motor housing,

iii. resilient support leg means integral with the cylindrical portion of said body portion and extending radially outwardly therefrom,

iv. said end supports being formed of a relatively soft flexible material and sized such that when said blower housing sections are joined, said end supports are clamped thereby to resiliently support said motor and blowers away from said blower housing.

2. The blower assembly of claim 1 wherein:

a. said resilient support leg means comprises a plurality of spaced apart support legs,

b. said cylindrical portion of each said end support body portion is provided a gap for each said support leg,

c. each said support leg comprises two spaced apart leg members each of which is integral with an end of a respective gap and which diverge outward from each other, and a flexible arcuate shaped bridge portion connecting the outer ends of said leg members of a said respective support leg.

3. An end support for attachment to the housing of a blower motor for supporting said motor in a blower housing, with said blower motor having shaft portions extending from opposite ends thereof, with said motor housing having a generally cylindrical portion coaxial with said shaft portions and end walls integral with the cylindrical portion and disposed generally transversely of said shaft portions, said end support comprising:

i. a body portion having a generally cylindrical portion disposed coaxially with a respective said motor shaft portion and an end wall disposed generally transversely of a respective said motor shaft portion,

ii. said body portion further having a concavity formed by interior surfaces of said cylindrical portion and said respective end wall, with said concavity shaped to conformingly fit the corresponding cylindrical and end wall portions of said motor housing,

iii. resilient support leg means comprising a plurality of spaced apart support legs integral with the cylindrical portion of said body portion and extending radially outwardly therefrom, with said cylindrical portion being provided a gap for each said support leg, and with each said support leg comprising two spaced apart leg members each of which is integral with an end of a respective said gap and which diverge outward from each other with a flexible arcuate shaped bridge portion connecting the outer ends of said leg members of a respective said support leg,

iv. said end support being formed of a relatively soft flexible material and sized such that said end support may be clamped by said blower housing so as to resiliently support said motor in said blower housing.
