Definitions

  • the present invention relates generally to a latching mechanism for band clamps, and more particularly, to a T-bolt clamp for mechanically fastening objects together.

  • the band 14 has a first loop end 20 and a second loop end 22 and is adapted to mechanically fasten objects together (not shown).
  • the objects can include any object that can be mechanically fastened or connected to another object.
  • a non- limiting example includes mechanically attaching a conduit, such as a hose, tube, or pipe to another conduit.
  • the loop ends 20, 22 can be formed by a portion of the band 14 being bent back and attached to the outer surface 18 of the band 14 by welding, crimping, mechanical fasteners such as rivets, or by any other suitable means.
  • the first loop end 20 includes two laterally-spaced first end bearing loops 24 defining a first end cutout 25 therebetween.
  • the second loop end 22 includes two laterally-spaced second end bearing loops 26 defining a second end cutout 27 therebetween.
  • the assembly 12 includes a latch bolt 30 having a head portion 32 and a threaded shank portion 34, a trunnion 36, and a nut 38.
  • the head portion 32 of the bolt 30 is pivotally received within the first end bearing loops 24 on the first loop end 20 of the band 14.
  • the trunnion 36 includes a stem portion 40 having a first end 42 and a second end 44 and two opposed cylindrical members 46, (46' shown in Fig. 2), each extending laterally from the first end 42 of the stem portion 40 of the trunnion 36.

Referring to Figs. 1-3, the shank portion 34 of the bolt 30 passes through the first end cutout 25 and the second end cutout 27 through the passageway of the trunnion 36, and the nut 38 is threadably received on the shank portion 34 of the bolt 30.
  • a gap bridge 50 is attached to the first loop end 20 and extends to the second loop end 22 of the band 14. The gap bridge 50, which is made of a rigid metal, protects an object from being damaged by the loop ends 20, 22 whenever the loop ends 20, 22 are drawn toward one another.
  • the flexible band 14 is fastened to an object or objects such as a conduit
  • a nut 38 is threadably fastened to the shank portion 34 and rotated toward the head portion 32 of the bolt 30, thus contacting the second end 44 of the stem portion 40 of the trunnion 36. As the nut 38 continues to move toward the head portion 32 of the bolt 30, the loop ends 20, 22 draw closer to each other, thereby tightening the band 14 around an object.
  • T-bolt clamp 10 requires the gap bridge 50 which adds extra materials and cost to the construction of the clamp 10. It would be advantageous if a portion of the band 14 could be used as the gap bridge 50, thus eliminating this extra metal piece. It would also be advantageous if the latch assembly 12 occupied less space on the band 14 while maintaining its strength, thus providing an improved low profile T-bolt clamp.

Abstract

La présente invention a trait à collier de serrage comportant un collier annulaire comprenant une boucle du support à une extrémité et une pince à son extrémité opposée. Le collier de serrage utilise une attache de boulon à T comportant un écrou et un boulon à T comprenant une tête et une tige filetée. L'attache relie la boucle de support et la pince de sorte que le serrage de l'attache tire les deux extrémités du collier en rapprochement. La pince comprend des parois latérales espacées et une paroi de fond qui lui procurent conjointement une section transversale en U qui définit un passage ouvert dimensionné pour la réception de la tige du boulon à T. Dans un mode de réalisation, la tête du boulon à T est reliée à la boucle de support et aux filets d'écrou sur la tige et engage la pince pour tirer les extrémités du collier en rapprochement. Dans un autre mode de réalisation, la tête engage la pince et un goujon est utilisé au niveau de la boucle de support pour engager l'écrou pour réaliser le serrage.
