Abstract
Description
La présente invention concerne une perche de prise de son pour le cinéma et l'audio-visuel
Elle est réalisée en matériaux composites s fibres de verre et de carbone , "kevlar" ou alumine , enrobées de résine polyester ou "époxy".The present invention relates to a sound recording pole for cinema and audio-visual
It is made of composite materials with glass and carbon fibers, "kevlar" or alumina, coated with polyester or "epoxy" resin.
Les tubes au nombre de quatre à cinq par perche , sont les uns par rapport aux autres de diamètre décroissants . Un système de tonction-verrouillage permet , à volonté , le coulissement des tube'r entre eux . (!r)
Cr système de Jonction-verrouillage de type mandrin est composé de deur bagues
La première de ces deux bagues (Fig I & 2) dite bague male réalsée en "téflon", "polyéthylène", "polypropylène", "P.V.C.The tubes, four to five in number per pole, are in relation to each other of decreasing diameter. A tonction-locking system allows, at will, the sliding of the tubes between them. (! r)
Cr Mandrel-type Junction-locking system is made up of two rings
The first of these two rings (Fig I & 2) called male ring realized in "teflon", "polyethylene", "polypropylene", "PVC
ou "rilsan" , présente un ailsage (A) intérieur équivalent au dia -mètre extérieur d'un tube quelconque de la perche , à l'exclusion du premier le plus gros
L'extérieur de cette bague présents, dans le sens d''allon-- -gement de la perche 4parties distinctes s
- une partie (3) d'un diamètre extérieur égal au diamètre
intérieur d'un tube de diamètre immédiatement supérieur
au tube coulissant à l'intérieur de cette' bague , cette
partie se logeant jusqu'à la saillie ((S) à l'intérieur
du tube le plus gros du couple de tubes ainsi déterminé
et est maintenue à ce tube par' collage
- d'une saillie (S) formant butée et limitant l'enfoncement
de la partie (B) dans le tube et est d'un diamètre égal
8u diamètre extérieur de ce tube
- d'une partie filetée (fF) , en saillie , å filets de
section triangulaire ou trapézoldale , et pouvant être
à entrée multiple
- et enfin d'une partie conique (K) à faible pente présentant
quatre fentes (f) décalées de 90 axées parallèlement à
l'axe d'alésage de cette bague
La deuxième bague (Fig 3 & 4) est réalisée en alliage d'aluminium type AU4G , AZ8GU ou autre
Son alésage présente plusieurs parties distinctes
- une première partie d'un alésage (S') de diamètre égal au
diamètre de la saillie ((S) de la bague male
- d'une partie filetée (F') en saillie intérieure à filets'
de section triangulaire ou trapezoidale et pouvant être à
entrée multiple
- d'une partie conique (K') à faible pente.or "rilsan", has an internal fin (A) equivalent to the external diameter of any tube of the pole, excluding the first largest
The outside of this ring present, in the direction of allon-- -part of the pole 4 separate parts s
- a part (3) with an outside diameter equal to the diameter
inside a tube with an immediately larger diameter
to the sliding tube inside this' ring, this
part accommodating up to the projection ((S) inside
of the largest tube of the couple of tubes thus determined
and is held to this tube by 'bonding
- a projection (S) forming a stop and limiting sinking
of part (B) in the tube and is of equal diameter
8u outer diameter of this tube
- a threaded part (fF), projecting, with threads
triangular or trapezoidal section, and which can be
multiple entry
- and finally of a conical part (K) with a slight slope having
four slots (f) offset by 90 oriented parallel to
the bore axis of this ring
The second ring (Fig 3 & 4) is made of aluminum alloy type AU4G, AZ8GU or other
Its bore has several distinct parts
- a first part of a bore (S ') of diameter equal to
projection diameter ((S) of male ring
- a threaded part (F ') projecting inside with threads'
of triangular or trapezoidal section and which may be
multiple entry
- a conical part (K ') with a slight slope.
L"extérieur de cette bague pouvant Stre lisse ou moletée à volonté
La partie terminale de la perche reçoit une pièce (Fig 7 & 8 ) vissée et collée , filetée en sa partie externe , qui permet la fixation au moyen d'un contre écrou , de tout.s sortes de suspensions
le talon de chaque tube de la perche à l'exeption du plus gnos reçoit des glissières en "téflon" (non représentées^) prmettant le glissement silencieux et l'auto-alignement di- chaque tube par rapport à celui qui le précède . (I)
Le talon du plus gros tube de la perche est muni d'un bloc de cahoutchouô (non représenté) destiné à prévenir les chocs .(I)
FONCTIONNEMENT 1
La partie (B) de la bague maie est enfilée Jusqu''à la saillie (S) dans rm tube (non représenté) quelconque de la perche à l'exclu -sion du plus petit , alors qu'un tube non représenté) de diamètre immédiatement inférieur au tube précédemment nommé est introduit à l'intérieur de cette bague
La bague femelle vient se visser sur la bague male . (Fig 5 & 6)
Au repos la partie conique (K) de la bague male ne recevant aucune contrainte de la partie conique (K'1) de la bague femelle permet le coulissement à volonté du tube (non représenté) interne à la bague male
Par un mouvement de rotation et donc de vissage de la bague femelle sur la bague male , le .cone(K') de la bague femelle venant s'appliquer sur le cone (K) de la bague maie , le sert et les fentes (f) du cone (K) de la bague maie viennent presser et immobiliser le tube dans une position déterminée par l'utilisateur
Ce système se répète pour choun des couples de tubes de la perche ;; chaque couple de tubes- recevant son propre système de jonction verrouillage . (I)
Cette perche ainsi réalisée , à l'aide de matériaux legers offre un allégement important , avantage primordial pour l'utilisateur qui tient plusieurs heures consécutives cet ensemble à bout de bras . (I)
A poids égal à un modèle comparable , on dispose ainsi d'une longueur JusquXà 20% de longueur supérieur . (I)
Lg système de Jonction verrouillage par mandrin offre , en outre l'avantage de pouvoir se prêter , grâce à la souplesse des matérisux employer aux irrégularités de diamètre des tubes. Cette souplesse permet aussi un fonctionnement parfaitement silencieux de l'ensemble.The outside of this ring can be smooth or knurled at will
The terminal part of the pole receives a piece (Fig 7 & 8) screwed and glued, threaded in its external part, which allows the fixing by means of a lock nut, of all kinds of suspensions
the heel of each tube of the pole with the exception of the most gnos receives slides in "teflon" (not shown ^) allowing the silent sliding and the self-alignment of each tube with respect to that which precedes it. (I)
The heel of the largest pole tube is provided with a block of cahoutchouô (not shown) intended to prevent shocks. (I)
OPERATION 1
The part (B) of the maie ring is threaded up to the projection (S) in a tube rm (not shown) of any pole except -sion of the smallest, while a tube not shown) diameter immediately below the previously named tube is introduced inside this ring
The female ring is screwed onto the male ring. (Fig 5 & 6)
At rest the conical part (K) of the male ring receiving no stress from the conical part (K'1) of the female ring allows the tube (not shown) internal to the male ring to slide at will
By a movement of rotation and therefore of screwing of the female ring on the male ring, the .cone (K ') of the female ring coming to apply on the cone (K) of the male ring, serves it and the slots ( f) of the cone (K) of the maie ring press and immobilize the tube in a position determined by the user
This system is repeated for choun couples of tubes of the pole; each pair of tubes - receiving its own locking junction system. (I)
This pole thus produced, using light materials offers significant relief, a primary advantage for the user who holds this set for several hours at arm's length. (I)
At a weight equal to a comparable model, we thus have a length Up to 20% longer. (I)
Lg mandrel locking junction system offers, in addition the advantage of being able to lend itself, thanks to the flexibility of the materials used to irregularities in the diameter of the tubes. This flexibility also allows perfectly silent operation of the assembly.
(I) Les paragraphes terminé par ce renvoi , font l'objet d'un dépot de brevet , ce Jour , par nous, , sous le Na concernant une perche inventés par nous à système de jonction verrouillage par excentrique (I) The paragraphs ended by this reference, are the subject of a patent deposit, this Day, by us, under the Na concerning a pole invented by us with junction system locking by eccentric
