Abstract
Encircling clamps of a flexible elongated body fitted at a first end with a pair of parallel arms encircling a bay open at their extremities, and at the other end with a tongue that is insertable into the bay. One arm of the bay is a spring having restoring force when flexed away from the other arm, and ratchet teeth on its inner surface extending only part way from the opening to the interior of the bay. The tongue has mating ratchet teeth extending a longer distance so that when the tongue is inserted into the bay it can be adjustably positioned therein while engaging all the ratchet teeth of the spring arm. The closed device can be opened by lifting the spring arm away from the tongue. Means are provided to pull the tongue into the bay.
Claims14
An encircling device for clamping a hose or the like comprising a flexible elongated body having first and second ends which interlock adjustably to close the device, the first end having a bay formed of two arms extending a first distance substantially parallel to each other from that end, one arm located radially outward of the other when the device is closed having tooth means oriented radially inward toward the other arm and extending from the extremity of said one arm back toward said first end a limited distance which is substantially less than said first distance, the remainder of said one arm being without tooth means and substantially smooth providing a region in said bay for freely receiving said second end, means resiliently urging said one arm with said tooth means toward the other arm of said bay, the second end having substantially exclusively a tongue fitted with tooth means oriented radially outwardly when the device is closed and extending along one side of said tongue a third distance longer than said limited distance for adjustably interlocking with all of the teeth in said bay.
In an encircling device having a flexible elongated body fitted at its first and second ends with respective first and second interlocking means for closing the device around an article or articles to be encircled, the improvement wherein the first interlocking means comprises first and second arms extending substantially parallel to each other from said first end to form a bay having an opening between extremities of said arms remote from said first end, the second arm being a spring for developing a restoring force if its extremity is moved away from the first arm so as to widen said opening, the second arm having on a surface confronting the second arm a first row of interlocking elements extending only part way into the bay from said extremity leaving an inner region of said bay free of interlocking elements, and the second interlocking means comprising a tongue extending from said second end and having along one side a second row of interlocking elements running from the extremity of said tongue toward said second end for engaging with the interlocking elements of said first row when said tongue is moved into said bay through said opening, said second row being substantially longer than said first row so that interlocking elements of said second row nearer to said extremity of said tongue will be in said inner region when interlocking elements of said second row nearer to said second end are engaged with interlocking elements of said first row, said second arm being disposed outward of said first arm when said device is closed, whereby said device when closed can be opened by moving the extremity of said second arm further outward to widen said opening and disengage all the interlocking elements of said first row from the interlocking elements of said second row.
