Apparatus for gastight sealing and detachable fastening of an inflated air balloon

Abstract

The apparatus has a fork ( 4 ), attached to one end of a rod ( 1 ) and the fork carrying over its both arms a ring ( 5 ), which is provided with an opening ( 8 ). A stiff tongue ( 6 ), which extends up to the middle of the ring, is placed on the ring ( 5 ) in a way that it can be swivelled. The length of the tongue ( 6 ) is approximately 1 to 2 mm more than the distance (a) between the revolving axis (A-A ) of the ring ( 5 ) and the base point ( 10 ) of the fork ( 4 ). Below the fork ( 4 ), the rod ( 1 ) carries noses ( 9 a/ 9 b ), provided with slots (E), for clamping the balloon neck (H). After the balloon neck (H) has been inserted through the opening ( 8 ) in the ring ( 5 ), which has been swivelled by approximately 90 degrees, the tongue ( 6 ) snaps over the base point ( 10 ) of the fork ( 4 ) and prevents thereby the springing back of the ring ( 5 ) to its initial position. With this, a single part production, a secure fastening and a space saving storage become feasible.

1 . An apparatus for gas tight sealing and detachable fastening of an air balloon, made of plastic, comprising a head piece and a rod, which is connected with the head piece and is used for carrying the balloon, wherein the head piece, placed at one end of the rod, has two arms to form a fork, the arms bent in a way at least closely resembling a semi circle and at the end of the arms, a ring with an opening being so fixed in a swiveling manner that it can swing out from its initial position at the plane of the fork about a swiveling axis A-A, which connects the two fork ends in a straight line and then it forms almost a right angle with the rod axis, and wherein a stiff tongue is fixed in a swiveling manner at the inner side of the ring, the length of the tongue being such that in the a use position of the apparatus, he tongue lies on a side of the fork, which is opposite to a neck, preventing thereby the ring from springing back in a direction of a rest position of the tongue, wherein, further, noses are constructed on the rod segment adjacent to the fork.  
   
   
       2 . Apparatus according to  claim 1 , wherein the tongue and the opening of the ring are situated in the rod axis.  
   
   
       3 . Apparatus as per  claim 3 , according to  claim 1 , wherein the tongue stretches from inside of the ring up to the center of the ring and crossing the ring.  
   
   
       4 . Apparatus according to  claim 3 , wherein the length of the tongue is somewhat more, than the distance between the swiveling axis of the ring and the base point of the fork.  
   
   
       5 . Apparatus according to  claim 1 , wherein the ring has on it's the opening two projections, which extend inside the ring space.  
   
   
       6 . Apparatus according to  claim 1 , wherein the rod is H-shaped in cross section.  
   
   
       7 . Apparatus according to  claim 1 , wherein the apparatus is formed of a single injection molded plastic part.  
   
   
       8 . Apparatus according to  claim 1 , wherein the noses form slots with the rod, for clamping the neck of the balloon.  
   
   
       9 . Apparatus according to  claim 1 , wherein the noses are provided with slots for clamping the neck of the balloon.  
   
   
       10 . Apparatus according to  claim 4 , wherein the length of the tongue is between 1 to 2 mm longer than the distance between the swiveling axis of the ring and the base point of the fork.
