French Abstract

Dispositif de montage pour support repliable comprenant un tube de cadre et un tube de support raccordés l'un à l'autre de manière à pouvoir pivoter au moyen de deux plaques d'assemblage symétriques, et un verrou coulissant qu'on déplace le long du tube de cadre pour bloquer le tube de support en position fonctionnelle. Le verrou coulissant a une tige de positionnement transversale et un capuchon d'extrémité qui se mettent en prise respectivement sur les plaques d'assemblage et le tube de cadre pour retenir le tube de support quand on le fait pivoter à la position fonctionnelle.

BACKGR9UND 0E THE INVENTIN
THE PRESENT INVENTION RELATES TQ A
FOLDING COLLAPSIBLE STAND MOUNTING DEVICE, AND
RELATES MORE PARTICULARLY TO SUCH A FOLDING
COLLAPSIBLE STAND MOUNTING DEVICE FOR FOLDING
COLLAPSIBLE DECK CHAIRS WHICH IS SAFE IN USE.
FIGURE 1 SHOWS A REGULAR FOLDING
COLLAPSIBLE DECK CHAIR THAT CAN BE FQLDED UP AND
ARRANGED INTO A FLAT CONFIGURATION WHEN NOT IN USE
THIS FOLDING COLLAPSIBLE DECK CHAIR IS COMPRISED OF
A FRAME MADE FROM STEEL TUBES, A CANVAS STRETC.YEn
WITHIN THE FRAME, AND A PLURALITY OF FOLDING
STANDS RESPECTIVELY PIVOTABLY CONNECTED TO THE
FRAME BY RESPECTIVE CONNECTORS. AS ILLUSTRATED
IN FIGURE 2, THE CONNECTOR IS COMPRISED OF TWO
SUBSTANTIALLY L-SHAPED CONNECTING PLATES CONNECTED
BETWEEN THE FRAME TUBE AND ONE STAND TU8E BY
RIVETS. WHEN INSTALLED, THE L-SHAPED CONNECTING
PLATES WITH THE STAND TUBE CAN BE TURNED ABOUT THE
RIVET ON THE FRAME TUBE BETWEEN THE OPERATIVE
'0 POSITION AND THE COLLAPSED POSITION. THE L-SHAPED
CONNECTING PLATES HAVE A RESPECTIVE RAISED PORTIQN

`. . ' 21gO330. .
AT AN INNER SIDE. WHEN THE L-SHAPED CONNECTING
PLATES ARE TURNED TO THE OPERATIVE POSITIONJ THE
RAISED PORTIONS OF THE L-SHAPED CONNECTING PLATES
ARE RESPECTIVELY MOVED INTO ENGAGEMENT WITH THE
FRAME TUBE OF THE DECK CHAIR TO HOLD THE STAND TUBE
IN THE OPERATIVE POSITION. WHEN THE STAND TUBE IS
TURNED IN THE REVERSED DIRECTION, THE RAISED
PORTIONS ARE RELEASED FROM THE FRAME TUBEJ AND
THEREFORE THE STAND TUBE CAN BE TURNED TO THE
COLLAPSED POSITION. THIS STRUCTURE OF FOLDING
COLLAPSIBLE DECK CHAIR IS NOT SAFE IN USE BECAUSE
THE RAISED PORTIONS OF THE L-SHAPED CONNECTING
PLATES TEND TO SLIP FROM POSITION WHEN THE USER
MOVES THE BODY WHILE LYING ON THE CHAIRJ CAUSING
THE DECK CHAIR SUDDENLY COLLAPSED. FURTHERMORE,
THE RAISED PORTIONS OF THE L-SHAPED CONNECTING
PLATES WILL BE WORN QUICKLY WITH USE.

OPERATIVE POSITION. THE SLIDING LOCK HAS A
TRANSVERSE LOCATING ROD AND AN END CAP WHICH ARE
RESPECTIVELY ENGAGED WITH THE CONNECTING PLATES AND
THE FRAME TUBE TO HOLD DOWN THE STAND TUBE WHEN THE
STAND TUBE IS TURNED TO THE OPERATIVE POSITION~

DETAILED DESCRIPTI0N 0F THE PREFERRED EMB0DIMENT
15REFERRING TO FIGURES 3 AND 4, A FOLDING
COLLAPSIBLE STAND MOUNTING DEVICE IN ACCORDANCE
WITH THE PRESENT INVENTION IS GENERALLY COMPRISED
OF A FRAME TUBE 11, A STAND TUBE 14, A CONNECTOR 2
CONNECTED BETWEEN THE FRAME TUBE 11 AND THE STAND
20TUBE 14, AND A SLIDING LOCK 3 CONTROLLED TO LOCK
THE STAND TUBE 14 IN THE OPERATIVE POSITION. THE
CONNECTOR 2 IS COMPRISED OF TWO SUBSTANTIALLY L-
SHAPED CONNECTING PLATES 21, EACH CONNECTING PLATE
21 HAVING A PLURALITY OF RIVET HOLES 22

` - : 2140330-
- - . .
RESPECTIVELY CONNECTED TO THE FRAME TUBE 11 AND THE
STAND TUBE 14 BY RESPECTIVE RIVETS 4. WHEN STAND
TUBE 14 AND THE FRAME TUBE 11 ARE CONNECTED
TOGETHER BY THE L-SHAPED CONNECTING PLATES 21, THE
STAND TUBE 14 CAN BE TURNED ABOUT THE RIVET ON THE
FRAME TUBE 11 BETWEEN THE OPERATIVE POSITION AND
THE COLLAPSED POSITION. THE L-SHAPED CONNECTING
PLATES 21 FURTHER HAVE A RESPECTIVE RETAINING HOLE
23 AT A SUITABLE LOCATION. THE SLIDING LOCK 3
COMPRISES A FLAT BASE 32, A BARREL 31 FORMED AT THE
FRONT END OF THE FLAT BASE 32 AND SLEEVED ONTO THE
FRAME TUBE 11 BEFORE THE INSTALLATION OF THE
CONNECTOR 2, AN END CAP 33 FORMED AT THE REAR END
OF THE FLAT BASE 32 AND HAVING TWO OUTWARD FLANGES
34 BILATERALLY DISPOSED AT THE TOP FOR THE HOLDING
OF THE HANDS DURING THE OPERATION OF THE SLIDING
LOCK 3, AND A TRANSVERSE LOCATING ROD 35 DISPOSED
ON THE FLAT BASE 32 NEAR THE OUTWARD FLANGES 34.
THRQUGH THE OUTWARD FLANGES 34, THE SLIDING LOCK 3
CAN BE CONVENIENTLY MOVED ALONG THE FRAME TUBE 11
BY HAND.
FIGURE 5 IS A SIDE VIEW OF FIGURE 4,
SHOWING THE SLIDING LOCK 3 MOVED BACKWARDS FROM THE
FRAME TUBE 11 TO THE UNLOCKING POSITION. ~HEN THE
FRAME TUBE 11 IS EXTENDED OUT, THE SLIDING LOCK 3

IS MOVED FROM THE UNLOCKING POSITION TO THE LOCKING
POSITION. WHEN THE SLIDING LOCK 3 IS MOVED TO THE
LOCKING POSITION AS SHOWN IN FIGURE ~, THE
TRANSVERSE LOCATING ROD 35 IS ENGAGED INTO THE
RETAINING HOLES 23 ON THE CONNECTING PLATES 21 AND
THE END CAP 33 IS COVERED ON ONE END OF THE FRAME
TUBE 11, AND THEREFORE THE STAND TUBE 14 IS STOPPED
FROM BEING MOVED RELATIVE TO THE FRAME TUBE 11.
WHEN THE SLIDING LOCK 3 IS MOVED OUTWARDS FROM THE
FRAME TUBE 11 TO RELEASE THE TRANSVERSE LOCATING
ROD 35 FROM THE RETAINING HOLES 23 AND THE END CAP
33 FROM THE FRAME TUBE 11, THE STAND TUBE 14 C4N
- THEN BE TURNED INWARDS AND CLOSELY ATTACHED TO THE
BOTTOM SIDE OF THE FRAME TUBE 11 AS SHOWN IN FIGURE
7.
FIGURE 8 SHOWS AN ALTERNATE FORM OF THE
PRESENT INVENTION IN WHICH A SPRING 5 IS CONNECTED
BETWEEN THE FRAME TUBE 11 AND THE END CAP 33 OF THE
SLIDING LOCK 3; THE CONNECTING PLATES 21 HAVE A
RESPECTIVE ARCHED EDGE 211 FOR GUIDING THE
TRANSVERSE LOCATING ROD 35. WHEN THE STAND TUBE
14 IS EYTENDED OUT, THE ARCHED EDGES 211 OF THE
CONNECTING PLATES 21 ARE TURNED TO FORCE THE
TRANSVERSE LOCATING ROD 35 OUTWARDS FROM THE FRAME

' :.- 2l4.n3~,
TUBE 11, CAUSING THE SPRING 5 PULLED OUTWARDS FROM
THE FRAME TUBE 11 (SEE FIGURES 9 AND 10). WHEN
THE STAND TUBE 14 IS MOVED TO THE OPERATIVE
POSITION, THE SLIDING LOCK 3 IS PULLED INWARDS
TOWARD THE FRAME TUBE 11, CAUSING THE TRANS\/ERSE
LOCATING ROD 35 ENGAGED INTO THE RETAINING HOLES 23
(SEE FIGURE 11). WHEN TO COLLAPSE THE STAND
TUBE 14, THE END CAP 33 IS PULLED OUTWARDS FROM THE
FRAME TUBE 11 TO RELEASE THE TRANSVERSE LOCATING
1U ROD 35 FROM THE RETAINING HOLES 23 (SEE FIGURE 12),
ALLOWING THE STAND TUBE 14 TO BE TURNED FROM THE
OPERATIVE POSITION TO THE COLLAPSED POSITION AN~
CLOSELY ATTACHED TO THE BOTTOM SIDE OF THE FRAME
TUBE 11.
