Abstract
A coolant hose clamp, in which an outer ring is provided with an inner cam surface configured for radial displacement of a plurality of arcuately configured clamping shoes, positioned within a retaining ring assembly. Rotation of the cam ring by a simple turning motion through a small angle relative to the retaining ring assembly actuates the clamping shoes radially inwards into clamping engagement with a flexible hose on a rigid fitting.
Claims18
A hose clamping device comprising:
- a pluraliy of clamping means, each of said clamping means including a piston portion and a shoe portion configured for clampingly engaging a portion of the periphery of a hose;
- means including slot means for receiving said piston portions therein for retaining said clamping means with said shoe portions in contiguous relation, with said shoe portions generally defining a circular hose receiving opening;
- a cam member having a plurality of cam edges generally equal in number to said plurality of clamping means;
- and
- cam follower means on each of said clamping means responsive to angular displacement of said cam member relative to said retaining means for radially displacing said shoe portions of said clamping means relative to the periphery of a hose within said hose receiving opening.
2 more elements
A hose clamping device comprising:
- an outer ring member of generally circular cross-section configured for hand grasping and having cam means on the interior thereof;
- retaining means assembled relative to said ring member for rotational displacement relative thereto, said retaining means includes hub means having radially extending slots therein;
- a plurality of clamping means, each of said clamping means including a shoe portion configured for clampingly engaging a portion of the periphery of a hose, and each of said clamping means including a portion within a corresponding slot of said hub means;
- means for assembling said clamping means to said retaining means for limited radial displacement relative thereto, with said shoe portions in contiguous relation and defining a generally circular hose receiving opening;
- and
- cam follower means in coacting engagement with said cam means and responsive to angular displacement of said outer ring member relative to said retaining means for radially displacing said shoe portions of said clamping means relative to the periphery of a hose within said hose receiving opening.
3 more elements
A hose clamping device comprising:
- a plurality of clamping means, each of said clamping means having a piston portion, a lobe portion and a shoe portion, said shoe portion being configured for clamping engaging a portion of the periphery of a hose,
- retaining means including hub means hub having radially extending slots therein, the piston portion of each of said clamping means being positioned within a corresponding slot of said hub means for limited radial displacement relative thereto, with said shoe portions in contiguous relation and defining a generally circular hose receiving opening;
- an outer ring member of generally circular cross-section configured for hand grasping assembled relative to said retaining means for rotational displacement related thereto, said ring member including means for coacting engagement with said lobe portions and responsive to angular displacement of said outer ring member relative to said retaining means for radially displacing said shoe portions of said clamping means relative to the periphery of a hose within said hose receiving opening.
