Encircling devices

Claim 2

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.

Claim 3

An encircling device according to claim 1 including means to pull said tongue into said bay.

Claim 4

An encircling device according to claim 2 wherein said means to pull said tongue are located substantially at the extremity of said tongue.

Claim 5

An encircling device according to claim 3 including pulling members extending laterally from said tongue for enabling said tongue to be grasped at both sides at said extremity and pulled into said bay.

Claim 6

An encircling device according to claim 1 including means to guide said tongue into said bay.

Claim 7

An encircling device according to claim 5 including means forming a channel for guiding said tongue into said bay.

Claim 8

An encircling device according to claim 6 wherein said channel is formed on said tongue and embraces said one arm with tooth means when said tongue is inserted into said bay.

Claim 9

An encircling device according to claim 7 including means to pull said tongue into said bay, comprising shoulder means provided by said means forming said channel.

Claim 10

An encircling device according to claim 4 including additional pulling members extending laterally from substantially said first end for enabling said device to be pulled at said end toward said extremity of said tongue.

Claim 11

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.

Claim 12

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.

Claim 13

An encircling device according to claim 10 including first and second closure pads extending outwardly from the extremity of said second arm and from the region of juncture of said tongue and said second end, respectively.

Claim 14

An encircling device according to claim 10 including means to pull said tongue into said bay.

Claim 15

An encircling device according to claim 10 including means to guide said tongue into said bay.

Claim 16

An encircling device according to claim 12 including means substantially at said first end of said elongated body providing a reference toward which to pull said tongue into said bay.
