Definitions
- the present invention relates to suspension devices with self-locking jaws, for example used as wall hangers to hold an object vertically.
- Such a self-locking jaw suspension device can include a base and at least a couple of two jaw blocks mounted rotating on the base along two parallel axes, with fixing means the gap between the jaw blocks and the base.
- the jaw blocks from couple of jaw blocks are symmetrical to each other with respect to transverse median plane which separates them, and have bearing faces eccentric curvilinear developing between a first end away from the axis and a second end closer to the axis.
- Blocks jaws pivoting about their respective axes, between a position of clamping in which the respective first end portions of bearing faces are facing each other, close together or bearing one against the other, and a liberation position in which the second respective end portions of bearing faces are opposite from each other to leave a free space between the two blocks jaws.
- the object to hang is engaged from bottom to top between the two jaws, spreading them, after which the weight of the object tends to make rotate the soft jaws in the direction of their approximation, both jaws then squeezing the object on both sides and oppose its fall.
- An improvement consists in providing a device for synchronization, which ensures the synchronization of the jaw blocks of the couple of jaw blocks in reverse rotations around their respective axes.
- a device for synchronization which ensures the synchronization of the jaw blocks of the couple of jaw blocks in reverse rotations around their respective axes.
- the problem proposed by the present invention is to design a new jaw hanger structure self-locking, in which the synchronization device has a particularly simple, reliable and inexpensive structure, excluding certainly any risk of blocking, jamming, seizing.
- Another object of the invention is to allow the realization of such a suspension device with self-locking jaws made of simple materials, for example wood, and according to traditional machining operations, without requiring operations of complex and expensive assembly.
- the device synchronization includes a rod with two parallel ends connected to a central part by bent portions, the portion rod center being near the base, the first end of rod being engaged in a first hole of the first jaw block, the second rod end being engaged in a second hole of the second jaw block of the pair of jaw blocks, the first and second holes being parallel to the corresponding axis of rotation and spaced from said axis of rotation by a predetermined spacing, the first hole being in the first jaw block area extending between the axis of rotation and the second end portion of the bearing face, the second hole being in the second jaw block area extending between the axis of rotation and the first end portion of bearing face.
- each block jaw is held on the base by a head screw, freely journalled in an axial hole in the jaw block, its head resting against the face anterior of the jaw block, the end of the screw rod passing through without clearance an axial hole in the base and receiving a clamping nut bearing against the rear face of the base, with a tubular spacer engaged on the screw rod and interposed between the front face of the base and the face posterior of the jaw block to determine the distance separating the block jaw and base.
- the self-locking jaw suspension device comprises a base 1 and at least a couple of two jaw blocks 2 and 3 mounted to rotate on the base 1 along two respective parallel axes 4 and 5.
- Each of the jaw blocks such as the jaw block 2 is limited by an anterior face 6, a posterior face 7, both flat and parallel to each other, and perpendicular to the respective axis 4, and a peripheral face 8.
- the peripheral face portion 8 which is facing the other jaw block is a support face 9, curvilinear eccentric, developing between a first end 10 distant from the respective axis of rotation 4 and a second end 11 close to the axis of rotation.
- the second jaw block 3 comprises a bearing face 12 extending between a first end 13 and a second end 14.
- the axes of rotation 4 and 5 are spaced apart by a distance suitable so that the jaw blocks 2 and 3 can pivot between a clamping position illustrated in Figure 1 and a release illustrated in FIG. 2.
- the first respective end portions 10 and 13 of bearing faces 9 and 12 are opposite one another, close together or in support one against the other.
- the second respective end portions 11 and 14 of the faces support 9 and 12 are facing each other to leave a space free 15 between the two jaw blocks 2 and 3.
- a synchronization device ensures the synchronization of rotation of the jaw blocks 2 and 3 of the flow of jaw blocks according to reverse rotations around their respective axes 4 and 5, between the clamping position illustrated in Figure 1 and the release position illustrated in figure 2.
- the synchronization device comprises a rod 16 with two ends 17 and 18 parallel, as can be seen better in FIG. 3, the ends 17 and 18 being connected to a portion central 19 by two respective bent portions 20 and 21.
- the portion rod center 19 can for example be rectilinear, and be arranged near the base 1.
- the first rod end 17 is engaged in a first blind hole 22 of the first jaw block 2, while the second end 18 of rod is engaged in a second blind hole 23 of the second block jaw 3 of the pair of jaw blocks.
- the first and second holes 22 and 23 are parallel to the corresponding axis of rotation 4 or 5, and spaced apart of said axis 4 or 5 substantially along the same predetermined spacing L.
- the first hole 22 is in the area of first jaw block 2 extending between the axis of rotation 4 and the second end portion 11 from the front support 9.
- the second hole 23 is in the area of the second jaw block 3 extending between the axis of rotation 5 and the first end portion 13 support face 12. In the clamping position, the rod 16 is thus arranged in an obligatory orientation illustrated in FIG. 1.
- a first stop 25 projecting from the base 1, and limiting the movement of the rod 16 beyond the release position: on FIG. 2, the rod 16 comes to bear against the first stop 25, preventing additional rotational movement of the jaw blocks 2 and 3 beyond the release position.
- a second stop 24 protruding from the base 1, and limiting the movement of the rod 16 beyond the clamping position: in FIG. 1, the rod 16 bears against the second stop 24, prohibits rotation additional jaw blocks 2 and 3 beyond the position of Tightening. It will be noted that this second stop 24 may be useless if, in the clamping position, the first ends 10 and 13 of faces 9 and 12 of the jaw blocks 2 and 3 come to bear against one the other above the plane passing through the two axes of rotation 4 and 5.
- each jaw block such as the jaw block 2 is held on the base 1 by a screw 26 with head 27, freely rotating in an axial hole 28 of the jaw block 2, the head 27 bearing against the anterior face 6 of the block jaw 2, the end portion 126 of rod 26 of screw passing through without clearance an axial hole 29 of the base 1 and receiving a tightening nut 30 carrying against the rear face 31 of the base 1.
- a tubular spacer 32 is engaged on the screw rod 26, and interposed between the front face 33 of the base 1 and the rear face 7 of the jaw block 2, to determine the spacing E separating the jaw block 2 and the base 1.
- a locking nut 38 can advantageously be provided, mounted on the intermediate part of the rod screw 26, to ensure a tightening of the base 1 on its two faces.
- the screw 26 to head 27 includes a proximal part of rod 226 with a smooth external surface and slightly longer than the thickness of the jaw block 2 increased by the length of the spacer 32.
- the proximal part of the rod 226 is connected by a shoulder 326 to the end portion 126 of the rod itself threaded and of reduced section.
- a washer 138 is engaged between the shoulder 326 and the base 1. This improves, at cost reduced, the freedom of rotation of the jaw block 2, and it facilitates the mounting.
- the base 1 could advantageously be made of wood.
- Blocks jaws can also be made of wood.
- the bearing faces 9 and 12 of the jaw blocks 2 and 3 are of preferably covered with a layer 34 or 35 of elastic material compressible and non-slip.
- the base 1 is generally parallelepiped and flat.
- the base carries, on one of its main faces, a single pair of two jaw blocks 2 and 3.
- a base 1 formed of a strip elongated along a longitudinal axis and bearing, on one of its faces main, a row of several pairs of identical jaw blocks to jaw blocks 2 and 3, the first ends of the bearing faces are located on the same side of the longitudinal axis of the base.
- the base 1 In use, as illustrated in Figures 4 and 5, the base 1 is fixed to a wall, so that the two axes 4 and 5 are horizontal and placed substantially on the same horizontal plane.
- An object 36 such as a snowboard, can be engaged between the two jaw blocks 2 and 3 in intermediate opening position, and the object's own weight 36, tending to move it down, causes the blocks to rotate jaws 2 and 3 in the clamping direction, so that the jaw blocks 2 and 3 tighten the object 36 and prohibit its movement down.
- For pick up the object just move it slightly upwards.
- to engage the object between the jaw blocks 2 and 3 initially in the clamping position of FIG. 1 it suffices to engage the object 36 in moving it up against the intermediate part of the jaw blocks 2 and 3, and jaw blocks 2 and 3, by rotation, move apart to authorize the engagement of object 36 to position illustrated in figure 5.

Description
La présente invention concerne les dispositifs de suspensions à mâchoires autobloquantes, par exemple utilisés comme suspensions murales permettant de tenir un objet verticalement.The present invention relates to suspension devices with self-locking jaws, for example used as wall hangers to hold an object vertically.
Un tel dispositif de suspension à mâchoires autobloquantes peut comprendre un socle et au moins un couple de deux blocs mâchoires montés rotatifs sur le socle selon deux axes parallèles, avec des moyens fixant l'écart entre les blocs mâchoires et le socle. Les blocs mâchoires du couple de blocs mâchoires sont symétriques l'un de l'autre par rapport au plan transversal médian qui les sépare, et ont des faces d'appui curvilignes excentrées se développant entre une première extrémité éloignée de l'axe et une seconde extrémité rapprochée de l'axe. Les blocs mâchoires pivotant autour de leurs axes respectifs, entre une position de serrage dans laquelle les premières portions d' extrémité respectives de faces d'appui sont en regard l'une de l'autre, rapprochées ou en appui l'une contre l'autre, et une position de libération dans laquelle les secondes portions d'extrémité respectives de faces d'appui sont en regard l'une de l'autre pour laisser un espace libre entre les deux blocs mâchoires. L'objet à accrocher est engagé de bas en haut entre les deux mâchoires, en les écartant, après quoi le poids de l'objet tend à faire pivoter les doux mâchoires dans le sens de leur rapprochement, les deux mâchoires serrant alors l'objet de part et d'autre et s'opposent à sa chute.Such a self-locking jaw suspension device can include a base and at least a couple of two jaw blocks mounted rotating on the base along two parallel axes, with fixing means the gap between the jaw blocks and the base. The jaw blocks from couple of jaw blocks are symmetrical to each other with respect to transverse median plane which separates them, and have bearing faces eccentric curvilinear developing between a first end away from the axis and a second end closer to the axis. Blocks jaws pivoting about their respective axes, between a position of clamping in which the respective first end portions of bearing faces are facing each other, close together or bearing one against the other, and a liberation position in which the second respective end portions of bearing faces are opposite from each other to leave a free space between the two blocks jaws. The object to hang is engaged from bottom to top between the two jaws, spreading them, after which the weight of the object tends to make rotate the soft jaws in the direction of their approximation, both jaws then squeezing the object on both sides and oppose its fall.
Dans les structures simples, décrites dans CH-A-113 521, CH-A-193 030 ou CH-A-235 542, les blocs mâchoires ne sont pas synchronisés, et pivotent indépendamment l'un de l'autre.In the simple structures, described in CH-A-113 521, CH-A-193 030 or CH-A-235 542, the jaw blocks are not synchronized, and rotate independently of each other.
Un perfectionnement consiste à prévoir un dispositif de synchronisation, qui assure la synchronisation des blocs mâchoires du couple de blocs mâchoires selon des rotations inverses autour de leurs axes respectifs. Dans ce cas, il est possible de réaliser les blocs mâchoires en différents matériaux, en leur conférant des formes complexes réalisant simultanément le dispositif de synchronisation. Mais on est alors conduit à réaliser un dispositif relativement complexe, dans lequel le dispositif de synchronisation peut parfois se bloquer, se gripper à cause des poussières ou grains de sable venant se loger à l'intérieur, de sorte qu'un tel dispositif est relativement fragile et ne présente pas la fiabilité requise pour une utilisation sans précaution. Il en est ainsi, par exemple, dans les structures à engrenages décrites dans FR-A-321 861 ou dans DE-A-38 18 031.An improvement consists in providing a device for synchronization, which ensures the synchronization of the jaw blocks of the couple of jaw blocks in reverse rotations around their respective axes. In this case, it is possible to make the blocks jaws of different materials, giving them complex shapes simultaneously implementing the synchronization device. But we are then leads to a relatively complex device, in which the synchronization device can sometimes jam, seize up because of dust or grains of sand coming to lodge inside, so that such a device is relatively fragile and does not have the reliability required for careless use. It's like that, for example, in the gear structures described in FR-A-321 861 or in DE-A-38 18 031.
Le problème proposé par la présente invention est de concevoir une nouvelle structure de dispositif de suspension à mâchoires autobloquantes, dans lequel le dispositif de synchronisation présente une structure particulièrement simple, fiable et peu onéreuse, excluant de manière certaine tout risque de blocage, de coincement, de grippage.The problem proposed by the present invention is to design a new jaw hanger structure self-locking, in which the synchronization device has a particularly simple, reliable and inexpensive structure, excluding certainly any risk of blocking, jamming, seizing.
Un autre objet de l'invention est de permettre la réalisation d'un tel dispositif de suspension avec des mâchoires autobloquantes réalisées en des matériaux simples, par exemple en bois, et selon des opérations d'usinage traditionnelles, sans nécessiter des opérations de montage complexes et onéreuses.Another object of the invention is to allow the realization of such a suspension device with self-locking jaws made of simple materials, for example wood, and according to traditional machining operations, without requiring operations of complex and expensive assembly.
Pour atteindre ces objets ainsi que d'autres, dans un dispositif de suspension à mâchoires autobloquantes selon l'invention, le dispositif de synchronisation comprend une tringle à deux extrémités parallèles raccordées à une partie centrale par des portions coudées, la portion centrale de tringle étant à proximité du socle, la première extrémité de tringle étant engagée dans un premier trou du premier bloc mâchoire, la seconde extrémité de tringle étant engagée dans un second trou du second bloc mâchoire du couple de blocs mâchoires, les premier et second trous étant parallèles à l'axe de rotation correspondant et écartés dudit axe de rotation selon un écartement prédéterminé, le premier trou étant dans la zone de premier bloc mâchoire s'étendant entre l'axe de rotation et la seconde portion d'extrémité de face d'appui, le second trou étant dans la zone de second bloc mâchoire s'étendant entre l'axe de rotation et la première portion d'extrémité de face d'appui.To reach these and other objects in a device suspension with self-locking jaws according to the invention, the device synchronization includes a rod with two parallel ends connected to a central part by bent portions, the portion rod center being near the base, the first end of rod being engaged in a first hole of the first jaw block, the second rod end being engaged in a second hole of the second jaw block of the pair of jaw blocks, the first and second holes being parallel to the corresponding axis of rotation and spaced from said axis of rotation by a predetermined spacing, the first hole being in the first jaw block area extending between the axis of rotation and the second end portion of the bearing face, the second hole being in the second jaw block area extending between the axis of rotation and the first end portion of bearing face.
Selon une réalisation avantageuse et simple, chaque bloc mâchoire est tenu sur le socle par une vis à tête, tourillonnant librement dans un trou axial du bloc mâchoire, sa tête portant contre la face antérieure du bloc mâchoire, l'extrémité de tige de vis traversant sans jeu un trou axial du socle et recevant un écrou de serrage portant contre la face arrière du socle, avec une entretoise tubulaire engagée sur la tige de vis et interposée entre la face avant du socle et la face postérieure du bloc mâchoire pour déterminer l'écartement séparant le bloc mâchoire et le socle.According to an advantageous and simple embodiment, each block jaw is held on the base by a head screw, freely journalled in an axial hole in the jaw block, its head resting against the face anterior of the jaw block, the end of the screw rod passing through without clearance an axial hole in the base and receiving a clamping nut bearing against the rear face of the base, with a tubular spacer engaged on the screw rod and interposed between the front face of the base and the face posterior of the jaw block to determine the distance separating the block jaw and base.

Dans les modes de réalisation illustrés sur les figures, le
dispositif de suspension à mâchoires autobloquantes comprend un socle 1 et
au moins un couple de deux blocs mâchoires 2 et 3 montés rotatifs sur le
socle 1 selon deux axes parallèles respectifs 4 et 5. Comme on le voit en
particulier sur les figures 3, 6 et 7, des moyens tels que des entretoises
32 fixant l'écart E entre les blocs mâchoires 2 et 3 et le socle 1.In the embodiments illustrated in the figures, the
self-locking jaw suspension device comprises a
Chacun des blocs mâchoires tel que le bloc mâchoire 2 est limité
par une face antérieure 6, une face postérieure 7, toutes deux planes et
parallèles l'une à l'autre, et perpendiculaires à l'axe respectif 4, et
une face périphérique 8. La portion de face périphérique 8 qui est
orientée vers l'autre bloc mâchoire est une face d'appui 9, curviligne
excentrée, se développant entre une première extrémité 10 éloignée de
l'axe de rotation respectif 4 et une seconde extrémité 11 rapprochée de
l'axe de rotation. Each of the jaw blocks such as the
Ainsi, le deuxième bloc mâchoire 3 comprend une face d'appui 12
s'étendant entre une première extrémité 13 et une seconde extrémité 14.Thus, the
Les axes de rotation 4 et 5 sont écartés d'une distance
appropriée de telle façon que les blocs mâchoires 2 et 3 puissant pivoter
entre une position de serrage illustrée sur la figure 1 et une position de
libération illustrée sur la figure 2. En position de serrage illustrée sur
la figure 1, les premières portions d'extrémité respectives 10 et 13 des
faces d'appui 9 et 12 sont en regard l'une de l'autre, rapprochées ou en
appui l'une contre l'autre. En position de libération illustrée sur la
figure 2, les secondes portions d' extrémité respectives 11 et 14 des faces
d'appui 9 et 12 sont en regard l'une de l'autre pour laisser un espace
libre 15 entre les deux blocs mâchoires 2 et 3.The axes of

illustrée sur la figure 2.A synchronization device ensures the synchronization of
rotation of the
Selon l'invention, le dispositif de synchronisation comprend une
tringle 16 à deux extrémités 17 et 18 parallèles, comme on le voit mieux
sur la figure 3, les extrémités 17 et 18 étant raccordées à une portion
centrale 19 par deux portions coudées respectives 20 et 21. La portion
centrale 19 de tringle peut par exemple être rectiligne, et être disposée
à proximité du socle 1.According to the invention, the synchronization device comprises a
La première extrémité 17 de tringle est engagée dans un premier
trou borgne 22 du premier bloc mâchoire 2, tandis que la seconde extrémité
18 de tringle est engagée dans un second trou borgne 23 du second bloc
mâchoire 3 du couple de blocs mâchoires. Les premier et second trous 22 et
23 sont parallèles à l'axe de rotation correspondant 4 ou 5, et écartés
dudit axe 4 ou 5 sensiblement selon un même écartement L prédéterminé. Le
premier trou 22 est dans la zone de premier bloc mâchoire 2 s'étendant
entre l'axe de rotation 4 et la seconde portion d'extrémité 11 de face
d'appui 9. Le second trou 23 est dans la zone de second bloc mâchoire 3
s'étendant entre l'axe de rotation 5 et la première portion d'extrémité 13
de face d'appui 12. En position de serrage, la tringle 16 est ainsi
disposée selon une orientation oblige illustrée sur la figure 1.The
De façon équivalente, on pourra donner à la tringle 16 une
orientation oblique inverse, en plaçant le premier trou 22 dans la zone de
premier bloc mâchoire 2 s'étendant entre l'axe de rotation 4 et la
première portion d'extrémité 10 de face d'appui 9, et en plaçant le second
trou 23 dans la zone de second bloc mâchoire 3 s'étendant entre l'axe de
rotation 5 et la seconde portion d'extrémité 14 de face d'appui 12.Equivalently, we can give the rod 16 a
reverse oblique orientation, placing the
Par cette disposition de la tringle 16, on voit que la rotation
de l'un des deux blocs mâchoires 2 ou 3 génère la rotation synchronisée de
l'autre des deux blocs mâchoires 2 et 3, entre les positions de serrage et
de libération, la tringle 16 ayant une longueur constante.By this arrangement of the
Dans les modes de réalisation illustrés sur les figures, on a en
outre représenté une première butée 25, dépassant du socle 1, et limitant
le mouvement de la tringle 16 au-delà de la position de libération : sur
la figure 2, la tringle 16 vient en appui contre la première butée 25,
empêchant un mouvement de rotation supplémentaire des blocs mâchoires 2 et
3 au-delà de la position de libération.In the embodiments illustrated in the figures, we have
further shown a
De même selon un mode de réalisation, on peut prévoir une
seconde butée 24, dépassant du socle 1, et limitant le déplacement de la
tringle 16 au-delà de la position de serrage : sur la figure 1, la tringle
16 est en appui contre la seconde butée 24, interdisent la rotation
supplémentaire des blocs mâchoires 2 et 3 au-delà de la position de
serrage. On remarquera que cette seconde butée 24 peut être inutile si,
dans la position de serrage, les premières extrémités 10 et 13 de faces
d'appui 9 et 12 des blocs mâchoires 2 et 3 viennent en appui l'une contre
l'autre au-dessus du plan passant par les deux axes de rotation 4 et 5.Similarly, according to one embodiment, a
Dans les modes de réalisation illustrés sur les figures 6 et 7,
chaque bloc mâchoire tel que le bloc mâchoire 2 est tenu sur le socle 1
par une vis 26 à tête 27, tourillonnant librement dans un trou axial 28 du
bloc mâchoire 2, la tête 27 portant contre la face antérieure 6 du bloc
mâchoire 2, la portion d'extrémité 126 de tige 26 de vis traversant sans
jeu un trou axial 29 du socle 1 et recevant un écrou de serrage 30 portant
contre la face arrière 31 du socle 1. Une entretoise tubulaire 32 est
engagée sur la tige de vis 26, et interposée entre la face avant 33 du
socle 1 et la face postérieure 7 du bloc mâchoire 2, pour déterminer
l'écartement E séparant le bloc mâchoire 2 et le socle 1.In the embodiments illustrated in FIGS. 6 and 7,
each jaw block such as the
Dans la réalisation de la figure 6, un écrou de blocage 38 peut
avantageusement être prévu, monté sur la partie intermédiaire de tige de
vis 26, pour assurer un serrage du socle 1 sur ses deux faces. In the embodiment of FIG. 6, a
Dans le mode de réalisation préféré de la figure 7, la vis 26 à
tête 27 comprend une partie proximale de tige 226 à surface externe lisse
et de longueur légèrement supérieure à l'épaisseur du bloc mâchoire 2
augmenté de la longueur de l'entretoise 32. La partie proximale de tige
226 se raccorde par un épaulement 326 à la portion d'extrémité 126 de tige
elle-même filetée et de section réduite. Au montage, une rondelle 138 est
engagée entre l'épaulement 326 et le socle 1. On améliore ainsi, à coût
réduit, la liberté de rotation du bloc mâchoire 2, et on facilite le
montage.In the preferred embodiment of Figure 7, the
Le socle 1 put avantageusement être en bois. Les blocs
mâchoires peuvent également être en bois.The
Les faces d'appui 9 et 12 des blocs mâchoires 2 et 3 sont de
préférence recouvertes d'une couche 34 ou 35 de matériau élastiquement
compressible et antidérapant.The bearing faces 9 and 12 of the
Dans les modes de réalisation illustrés sur les figures, le

l'une de ses faces principales, un seul couple de deux blocs mâchoires 2
et 3.In the embodiments illustrated in the figures, the
En alternative, on peut prévoir un socle 1 formé d'une bande
allongée selon un axe longitudinal et portant, sur l' une de ses faces
principales, une rangée de plusieurs couples de blocs mâchoires identiques
aux blocs mâchoires 2 et 3, dont les premières extrémités de faces d'appui
sont situées d'un même côté de l'axe longitudinal du socle.Alternatively, one can provide a
En utilisation, comme illustré sur les figures 4 et 5, le socle
1 est fixé à un mur, de sorte que les deux axes 4 et 5 sont horizontaux et
placés sensiblement sur un même plan horizontal. Un objet 36, tel qu'une
planche à neige, peut être engagé entre les deux blocs mâchoires 2 et 3 en
position d'ouverture intermédiaire, et le propre poids de l'objet 36,
tendant à le déplacer vers le bas, provoque la rotation des blocs
mâchoires 2 et 3 dans le sens du serrage, de sorte que les blocs mâchoires
2 et 3 serrent l'objet 36 et interdisent son déplacement vers le bas. Pour
décrocher l'objet, il suffit de le déplacer légèrement vers le haut. De
même, pour engager l'objet entre les blocs mâchoires 2 et 3 initialement
en position de serrage de la figure 1, il suffit d'engager l'objet 36 en
le déplacant vers le haut en appui contre la partie intermédiaire des
blocs mâchoires 2 et 3, et les blocs mâchoires 2 et 3, par rotation,
