Description

  

  Potenee extensible s'adaptant aux fenêtres.    L'invention a pour objet une     potence          extensible    s'adaptant aux fenêtres, suivant  la revendication du brevet principal, caracté  risée en ce que le bras de potence est supporté  par l'organe comportant des trous pour la  goupille, le levier étant articulé sur un sup  port reposant sur l'autre organe, l'ensemble  desdits organes étant entouré par un disposi  tif solidaire du support du     levier,    et qui com  porte, d'une part, au moins un collier dans  lequel passe l'organe support du bras de po  tence, et, d'autre part, au moins une chaîne  accrochée à ce collier, laquelle est fixée à  l'autre organe.  



  Le dessin ci-joint montre, à titre d'exem  ple, une forme d'exécution de l'objet de l'in  vention.  



  Un support 23 d'un bras de potence 24 est  percé de trous 25. La goupille 26 placée dans  l'un de ces trous s'appuie sur une fourche 27  solidaire du levier 28, articulée en 29 sur un  support 30 dont une embase 31 repose sur  un pilier 32 en bois. Un coin 33 enfoncé dans    une des fentes que     comporte    le support 30       s        'oppose   <B>,</B>     au        mouvement        du        levier.     



  Le support 23 passe dans les colliers 34,  35 solidaires d'une plaque 36 solidaire     elle-          même    du support 30. En avant du pilier 32,  des plaques 37, 38 solidaires respectivement  des colliers 34, 35 comportent des trous  d'accrochage pour des chaînes 89, 40. En  arrière du pilier 32 est un ensemble sembla  ble de plaques et de chaînes. Chaque chaîne  porte un organe en     pointe    pénétrant dans le  bois pour donner une     fixation    solide. Il s'a  git là d'un genre de     dispositifs    bien connu, et  c'est pourquoi le dessin n'en montre pas le  détail.



  Extensible potenee adapting to windows. The object of the invention is an extendable bracket adapting to windows, according to the claim of the main patent, characterized in that the bracket arm is supported by the member having holes for the pin, the lever being articulated on a support resting on the other member, all of said members being surrounded by a device integral with the support of the lever, and which comprises, on the one hand, at least one collar in which passes the support member of the control arm. po tence, and, on the other hand, at least one chain attached to this collar, which is attached to the other organ.



  The accompanying drawing shows, by way of example, one embodiment of the object of the invention.



  A support 23 of a stem arm 24 is pierced with holes 25. The pin 26 placed in one of these holes rests on a fork 27 integral with the lever 28, articulated at 29 on a support 30 including a base 31 rests on a wooden pillar 32. A wedge 33 driven into one of the slots in the support 30 opposes <B>, </B> the movement of the lever.



  The support 23 passes through the collars 34, 35 integral with a plate 36 itself integral with the support 30. In front of the pillar 32, the plates 37, 38 respectively integral with the collars 34, 35 have attachment holes for chains 89, 40. Behind pillar 32 is a similar set of plates and chains. Each chain carries a pointed member penetrating into the wood to give a solid fixation. This is a well-known kind of device, and that is why the drawing does not show the detail.

Claims

CLAIM Extendable bracket adapting to windows, according to the claim of the main patent, characterized in that the bracket arm is supported by the member having holes for the pin, the lever being articulated on a support resting on the another member, all of said members being rotated by a device integral with the support of the lever, and which comprises, on the one hand, at least one collar in which passes the support member of the jib arm, and, on the other hand hand, at least one chain attached to this collar, which is attached to the other organ.

SUB-CLAIM A jib crane as claimed in claim as described with reference to the accompanying drawing.
