Mounting system and method for night vision tubes
View Patent ↗A mounting system for night vision tubes includes a multi-part sleeve that opens in the manner of a clamshell to receive the tube. The sleeve includes a longitudinal seam or a partial longitudinal seam and opens around compliant hinge regions. The night vision tube engages a ramp section of the sleeve, urging the sleeve to open and then abuts against a front shoulder, causing the sleeve to clamp shut around the night vision tube. The tube is constrained between the front shoulder and a retaining shoulder. An indexing pin engages the night vision tube and the sleeve to maintain mutual rotational alignment. The sleeve and the tube are inserted into a housing of a night vision system.
1. A night vision system, comprising:
a night vision tube; and
a sleeve for surrounding the night vision tube in a housing, wherein the sleeve has a seam that divides the sleeve into two parts, wherein said seam extends partially longitudinally along the sleeve and the sleeve opens around compliant hinge regions that attach the two parts.
2. The night vision system as claimed in claim 1 , wherein the sleeve opens in the manner of a clamshell to receive the night vision tube.
3. The night vision system as claimed in claim 1 , wherein the sleeve comprises a ramp section, against which the night vision tube engages; causing the sleeve to open.
4. The night vision system as claimed in claim 1 , wherein the sleeve comprises a retaining shoulder and a front shoulder for constraining movement of the night vision in an axial direction.
5. The night vision system as claimed in claim 1 , wherein cut outs have been formed on the sleeve.
6. A method of mounting a night vision tube in a housing, the method comprising:
inserting the night vision tube into a multi-part sleeve for surrounding the night vision tube, wherein said multi-part sleeve has a sleeve opening around compliant hinge regions that connect the two parts of the sleeve to receive the night vision tube; and
closing the sleeve around the night vision tube and inserting the sleeve with the night vision tube into the housing.
7. The method as claimed in claim 6 , further comprising the sleeve opening in the manner of a clamshell.
8. The method as claimed in claim 6 , further comprising the night vision tube engaging a ramp section of the sleeve, urging the sleeve to open.
9. The method as claimed in claim 6 , further comprising constraining the night vision tube in an axial direction between a retaining shoulder of the sleeve and a front shoulder.
10. The method as claimed in claim 6 , wherein the night vision tube abuts against the front shoulder, causing the sleeve to clamp shut around the night vision tube.
11. The method as claimed in claim 6 , wherein an indexing pin maintains rotational alignment between the night vision tube and the sleeve.
12. The method as claimed in claim 6 , wherein cut outs have been formed on the sleeve.
13. A night vision system, comprising:
a night vision tube; and
a sleeve for surrounding the night vision tube in a housing, wherein the sleeve has a seam along the sleeve that divides the sleeve into two parts, wherein the sleeve opens around compliant hinge regions that attach the two parts.
14. The night vision system as claimed in claim 13 , wherein the sleeve opens in the manner of a clamshell to receive the night vision tube.
15. The night vision system as claimed in claim 13 , wherein the sleeve comprises a front compression buffer portion.
16. A night vision system, comprising:
a night vision tube; and
a sleeve for surrounding the night vision tube in a housing, wherein the sleeve has a seam that divides the sleeve into two parts, wherein the sleeve comprises a front compression buffer portion.
17. A night vision system, comprising:
a night vision tube;
a sleeve for surrounding the night vision tube in a housing, wherein the sleeve has a seam that divides the sleeve into two parts; and
an indexing pin that engages the night vision tube and the sleeve to maintain mutual rotational alignment.
