Description
Verrou de sûreté pour installation foraine et articles similaires. Actuellement le maintien à la position développée des pieds articulés sur le support tubulaire des tentes et parasols, a lieu en verrouillant le manchon coulissant avec une patte longitudinale solidaire du tube support, au moyen d'une goupille amovible retenue par une chaînette. Safety lock for fairground installation and similar articles. Currently maintaining the developed position of the articulated feet on the tubular support tents and umbrellas, takes place by locking the sliding sleeve with a longitudinal lug secured to the support tube, by means of a removable pin retained by a chain.
II est concevable que ce dispositif précaire d'im mobilisation laisse souvent à désirer par suite de l'arrachement de la chaînette retenant la goupille d'arrêt. D'autre part il est nécessaire d'engager ladite goupille dans des trous correspondants pour assurer la solidarisation du manchon et du tube support, opération souvent incommode à effectuer dans l'obscurité. It is conceivable that this precarious device im mobilization often leaves something to be desired as a result of the tearing of the chain retaining the locking pin. On the other hand it is necessary to engage said pin in corresponding holes to ensure the fastening of the sleeve and the support tube, often inconvenient operation to perform in the dark.
La présente invention a pour but de pallier ces inconvénients. Elle réalise en effet, d'une façon pratique et sûre le verrouillage automatique du manchon coulissant de l'articulation des pieds en position développée, sur le tube support des tentes et parasols, ou autres installations foraines. The present invention aims to overcome these disadvantages. It realizes, in a practical and safe way the automatic locking of the sliding sleeve of the foot joint in the developed position, on the support tube of the tents and parasols, or other fairground facilities.
A cet effet le manchon coulissant est pourvu, axé dans une chape support qui lui est solidaire, d'un levier d'arrêt à bascule rappelé par un ressort, se verrouillant automatiquement par accrochage sur le doigt transversal d'une chape d'arrêt, fixée sur le tube support formant l'un des mâts de l'installa tion. For this purpose the sliding sleeve is provided, axed in a support screed which is secured thereto, a rocker stop lever biased by a spring, automatically locking by hooking on the transverse finger of a stop yoke, attached to the support tube forming one of the masts of the installation.
Les détails de ce verrou, ainsi que les avantages qu'il procure, seront mieux compris en se référant au dessin annexé qui montre à titre indicatif, non restrictif, une réalisation pratique de l'invention. The details of this lock, as well as the advantages it provides, will be better understood with reference to the appended drawing which shows, by way of indicative, non-restrictive, a practical embodiment of the invention.
La fig. 1 est une vue montrant le profil du verrou de sûreté adapté sur le manchon coulissant d'articu lation des pieds d'une armature de tente, ou de parasol d'installation foraine, ledit verrou étant représenté en position préalable à l'accrochage. Fig. 1 is a view showing the profile of the safety lock adapted to the sliding sleeve articulating the feet of a tent frame, or of a fairground parasol, said latch being shown in position prior to the hooking.
La fig. 2 est une vue de profil identique à la pré cédente, montrant le manchon coulissant en position verrpuillée sur le tube support de l'installation. Fig. 2 is a profile view identical to the previous one, showing the sliding sleeve in the verrpuillée position on the support tube of the installation.
La fig. 3 est une vue de face du verrou de sûreté dont ii s'agit. La fig. 4 en est une vue de côté. Fig. 3 is a front view of the safety lock which is involved. Fig. 4 is a side view.
Ainsi que l'illustre le dessin, le manchon 1, coulissant sur le tube support 2 et assurant le déve loppement des pieds de l'installation, est pourvu d'une chape 3 réalisée dans un profilé en U par exemple. Cette chape 3, solidaire du manchon 1, comporte entre ses ailes latérales, un levier 4 articulé, à proximité de l'une de ses extérmités 5, sur un axe 6 qui le traverse. Cet axe est retenu par les ailes du U qui constituent la chape support 3. As illustrated in the drawing, the sleeve 1, sliding on the support tube 2 and ensuring the development of the feet of the installation, is provided with a yoke 3 made in a U-shaped profile for example. This yoke 3, integral with the sleeve 1, comprises between its lateral wings, a lever 4 hinged, near one of its exterérities 5, on an axis 6 which passes through it. This axis is retained by the wings of the U which constitute the support screed 3.
A l'une des extrémités 7 de la chape 3, l'écarte ment qui subsiste entre les ailes latérales, est ré- treint. A cet effet deux traits de scie permettent de rapprocher dans l'axe médian ces deux parties extrêmes 7 de la chape jusqu'à affleurer le levier 4. afin de le guider dans son mouvement d'oscillation autour de l'axe 6. Cette forme particulière de l'extré mité de la chape est plus visible fig. 4. At one of the ends 7 of the yoke 3, the gap which remains between the lateral flanges is reduced. For this purpose, two saw-cuts enable the two end portions 7 of the screed to be brought closer together in the median axis until the lever 4 is flush with the lever 4 in order to guide it in its oscillation movement about the axis 6. This shape peculiarity of the end of the screed is more visible fig. 4.
Le levier 4 est maintenu en constante butée dans le fond de la chape 3, au moyen d'un ressort 8 en corde à piano. Ce ressort 8 prend appui sur le dos 9 du levier de verrouillage 4, ensuite forme des boucles autour de l'axe d'oscillation 6 de part et d'autre dudit levier et bute enfin dans le fond de la chape support 3. The lever 4 is held in constant stop in the bottom of the yoke 3, by means of a spring 8 in piano wire. This spring 8 is supported on the back 9 of the locking lever 4, then forms loops around the axis of oscillation 6 on either side of said lever and finally abuts in the bottom of the support yoke 3.
A proximité de l'extrémité 10 du levier 4 prolon geant la chape 3, est pratiquée une encoche 11, ladite extrémité 10 formant une rampe pour faciliter l'accrochage du verrou. Near the end 10 of the lever 4 extending the yoke 3, is made a notch 11, said end 10 forming a ramp to facilitate the attachment of the latch.
Une chape d'arrêt 12 est rendue solidaire du tube support 2 de l'installation. Cette chape de petites dimensions est également réalisée dans un profilé en U et comporte un doigt d'accrochage transversal 13, sur lequel vient se verrouiller le levier précé dent 4 par son encoche 11, immobilisant ainsi le manchon coulissant 1 supportant le verrou. A stop yoke 12 is secured to the support tube 2 of the installation. This small-sized yoke is also made in a U-shaped profile and comprises a transverse gripping finger 13, on which the preceding lever 4 is locked by its notch 11, thereby immobilizing the sliding sleeve 1 supporting the latch.
II est aisé de comprendre que pour maintenir, à la position développée, les pieds articulés de Pins- taüation, ii suffit de faire coulisser de haut en bas <B>le</B> manchon 1 sur le support tubulaire 2. Lorsque le levier 4 arrive au droit du doigt 13, ce dernier le soulève afin dé permettre l'engagement de l'encoche <B>11.</B> Le verrouillage s'effectue donc automatiquement sous l'action du ressort 8, l'immobilisation du man chon 1 étant de la sorte assurée en toute sécurité. It is easy to understand that in order to maintain the articulated feet of the pins in the developed position, it is sufficient to slide the sleeve 1 downwards from the top to the tubular support 2. When the lever 4 reaches the right finger 13, the latter raises it to allow the engagement of the notch <B> 11. </ B> The lock is therefore automatically under the action of the spring 8, the immobilization of man chon 1 being thus ensured in complete safety.
Pour déverrouiller le dispositif, ii suffit de soulever l'extrémité 10 du levier 4 afin de dégager l'encoche 11 du doigt 13. Le manchon se trouve libéré et peut à nouveau coulisser sur le support tubulaire 2, dans le but de replier les pieds de l'installation. To unlock the device, simply lift the end 10 of the lever 4 to release the notch 11 of the finger 13. The sleeve is released and can slide again on the tubular support 2, in order to fold the feet of the installation.
Ii reste entendu que pour étendre le champ d'appli cation de ce verrou à tous genres de tentes et para sols comportant des pieds articulés, toutes modifica tions de détails peuvent être envisagées sans pour cela s'écarter du cadre de l'invention, notamment le ressort 8 rappelant le levier de verrouillage 4 peut prendre appui sur le côté opposé dudit levier, dans une encoche prévue à cet effet. Ii est également possible d'envisager le rappel de ce levier 4 au moyen d'un ressort à boudin, à lame, ou tout autre. Enfin la disposition du verrou peut être inversée en fixant la chape support 3 et son levier 4 sur le montant tubulaire 2, tandis que la chape d'arrêt 12 est de la sorte solidaire du manchon coulissant 1. It is understood that to extend the application of this lock to all kinds of tents and parols with articulated feet, any changes in details can be envisaged without departing from the scope of the invention, particularly the spring 8 recalling the locking lever 4 can bear on the opposite side of said lever, in a notch provided for this purpose. It is also possible to consider the return of this lever 4 by means of a coil spring, blade, or any other. Finally, the arrangement of the lock can be reversed by fixing the support clevis 3 and its lever 4 on the tubular upright 2, while the stop clevis 12 is of the kind secured to the sliding sleeve 1.
