Abstract
Description
La présente invention concerne des haltères du type comprenant une barre pourvue, à chacune de ses extrémités, d' une masse pesante. The present invention relates to dumbbells of the type comprising a bar provided at each of its ends with a heavy mass.
De tels haltéres sont très connus et très répandus et sont généralement, constitués d'une bande métallique comportant, à chacune de ses extrémités, un disque en acier qui constitue une masse pesante. Such dumbbells are very well known and widespread and generally consist of a metal strip comprising, at each of its ends, a steel disc which constitutes a heavy mass.
Ces halteres sont relativement chèrs et la presente invention vise un nouvel haltère beaucoup moins onéreux et d'une fabrication très simple. These dumbbells are relatively expensive and the present invention is a new dumbbell much less expensive and very simple to manufacture.
Le nouvel haltere objet de la présente invention est du type comprenant une barre pourvue drune masse pesante a chacune de ses extrémités, et est caractérisé en ce que chaque masse pesante comprend un manchon destiné à être enfilé sur l'extrémité correspondante de la barre et un bloc de ciment moulé sur le manchon, une ceinture de protection en caoutchouc étant fixée sur le bloc de ciment. The new dump object of the present invention is of the type comprising a bar provided with a heavy mass at each of its ends, and is characterized in that each heavy mass comprises a sleeve intended to be threaded on the corresponding end of the bar and a cement block molded onto the sleeve, a protective rubber belt being attached to the cement block.
On réalise ainsi, un, haltère tres bon marché et qui a un bel aspect fini
Suivant une autre caractéristique, le manchon est percé d'au moins un trou diamétral au voisinage de l'une de ses extrémités, la barre comportant, au voisinage de ses extrémités, des trous correspondants pour le passage de goupilles pour assujettir les masses sur la barre.We thus realize, a very cheap, dumbbell which has a beautiful finished appearance
According to another characteristic, the sleeve is pierced with at least one diametric hole in the vicinity of one of its ends, the bar comprising, in the vicinity of its ends, corresponding holes for the passage of pins to secure the masses on the closed off.
De préférence, chaque masse rasante est revêtue d' une mince couche de platre et est peinte. Preferably, each grazing mass is coated with a thin layer of plaster and is painted.
L'invention vise également un procédé de fabrication des masses pesantes destinées à équiper des halteres tels que ci-dessus définis, ledit procédé étant caractérise en ce qu'il consiste à placer dans un moule correspondant à la masse a réaliser, un manchon, à remplir le moule de ciment, mélange a de l'eau avec, eventuellement, une charge, après durcissement du ciment, à démouler la masse ainsi obtenue, à déposer sur celle-ci une mince couche de platre pour la rendre .lisse, à peindre ladite masse et à fixer à sa périphérie une ceinture élastique. The invention also relates to a method of manufacturing heavy weights intended to equip dumbbells as defined above, said method being characterized in that it consists in placing in a mold corresponding to the mass to be produced, a sleeve, to fill the mold with cement, mix with water with, possibly, a filler, after hardening of the cement, to demold the mass thus obtained, to deposit on it a thin layer of plaster to make it smooth, to paint said mass and to fix at its periphery an elastic belt.
Enfin, suivant une dernière caractéristique de 1 invention, celle-ci vise également un moule pour la réalisation des masses pesantes d'haltère réalisé suivant ledit pro cédez ledit moule étant caractérisé en ce qu'il comprend une premiere demi-coquille présentant dans son fond un trou du diamètre correspondant à celui du manchon, une deuxième demicoquille destinée à être fixée sur la première et présentant un trou aligné avec le trou de la première demi-coquille mais d'un diamètre supérieur à celui du manchon et une rondelle de centrage comportant un trou d'un diamètre correspondant a celui du manchon pour être engagée sur celui-ci et un diamètre exterieur correspondant au trou de la deuxième demicoquille. Finally, according to a last characteristic of 1 invention, it also relates to a mold for the production of heavy dumbbells made according to said pro cede said mold being characterized in that it comprises a first half-shell having in its bottom a hole of diameter corresponding to that of the sleeve, a second half-shell intended to be fixed on the first and having a hole aligned with the hole of the first half-shell but of a diameter greater than that of the sleeve and a centering washer comprising a hole with a diameter corresponding to that of the sleeve to be engaged thereon and an outside diameter corresponding to the hole of the second half-shell.
L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation particulier, donne à titre d'exemple seulement et représenté aux dessins annexés dans lesquels. The invention will now be described in more detail with reference to a particular embodiment, given by way of example only and shown in the accompanying drawings in which.
figure 1 est.une vue en perspective éclatée d'un haltère selon l'invention,
figure 2 montre, en coupe schématique, le mo-ule pour la réalisation des masses pesantes de l'haltère de la figure 1.FIG. 1 est. an exploded perspective view of a dumbbell according to the invention,
Figure 2 shows, in schematic section, the mo-ule for the realization of the heavy weights of the barbell of Figure 1.
A la figure 1,. on a représenté un haltère, comprenant une barre 1 sur laquelle sont fixées des poignées 2 et recevant à chacune de ses extrémités une masse pesante 3. In Figure 1 ,. a barbell has been shown, comprising a bar 1 on which handles 2 are fixed and receiving at each of its ends a heavy mass 3.
Chaque masse pesante est constituée d'un manchon 4 en matière plastique, sur lequel est moulé un corps en ciment ledit corps étant revêtu d'une mince couche de platre et peint. Each heavy mass consists of a plastic sleeve 4, on which a cement body is molded, said body being coated with a thin layer of plaster and painted.
Pour eviter, lorsqu'on laisse tomber l'haltère, que les masses pesantes soient endommagées, il est prévu, sur chacune de celles-ci, une ceinture en matière souple et elas- tique 8. To avoid damaging the heavy weights when the dumbbell is dropped, a belt of flexible and elastic material is provided on each of them 8.
La barre 1 comporte, au voisinage de ses -extrémités, des trous diametraux 9 tandis que les manchons 4 sont pourvus de trous correspondants 5. La fixation es masses pesantes sur les extrémités correspondantes de la barre 1 étant réalisée en faisant coincider les trous 5 et 9 et en engageant, à travers ceux-ci, des goupilles 6.Pour masquer lesdites goupilles, il peut etre prévu des capuchons 7. The bar 1 comprises, in the vicinity of its ends, diametrical holes 9 while the sleeves 4 are provided with corresponding holes 5. The fixing is heavy masses on the corresponding ends of the bar 1 being produced by making the holes 5 coincide and 9 and by engaging pins through them 6.To hide said pins, caps 7 can be provided.
A la figure 2, on a représente un moule 10 des.tiné la fabrication des masses pesantes 3. Ce. moule 10 est constitué d'une première demi-coquille ll dont le fond comporte, en son centre, un trou 14 destiné à recevoir l'une des extremites du manchon 4, ce trou ayant une dimension telle que le manchon soit engagé légèrement à force . Sur la demi-coquille ll est articulée sur un axe 12, une demi-coquille correspondante 18, les deux demi-coquilles etant assemblées par un organe de verrouillage 13. La demi-coquille 10 comporte un trou 15 aligné avec le trou 14 mais dont le diamètre est supérieur au diamètre externe du manchon 4. In Figure 2, there is shown a mold 10 des.tiné the manufacture of heavy masses 3. Ce. mold 10 consists of a first half-shell ll, the bottom of which comprises, in its center, a hole 14 intended to receive one of the ends of the sleeve 4, this hole having a dimension such that the sleeve is engaged slightly by force . On the half-shell ll is articulated on an axis 12, a corresponding half-shell 18, the two half-shells being assembled by a locking member 13. The half-shell 10 has a hole 15 aligned with the hole 14 but whose the diameter is greater than the external diameter of the sleeve 4.
Pour réaliser la masse pesante 3, on remplit le moule par l'espace libre ménagé entre la surface latérale du manchon 4 et le bord du trou 15 puis, lorsque le moule est plein, on met en place une rondelle 16 qui comporte un trou central correspondant au diamètre du manchon 14 tandis que son diamètre externe correspond au diamètre du trou 15. Ainsi le manchon se trouve centré et lorsque le ciment est p-ris, il suffit de procéder au démoulage. To make the heavy mass 3, the mold is filled by the free space provided between the lateral surface of the sleeve 4 and the edge of the hole 15 then, when the mold is full, a washer 16 is put in place which has a central hole corresponding to the diameter of the sleeve 14 while its external diameter corresponds to the diameter of the hole 15. Thus the sleeve is centered and when the cement is ready, it suffices to demold.
Bien entendu, l'invention n'est pas initée. au mode due réalisation qui vient d'être décrit et rRpresente, on pourra y apporter de nombreuses modifications de détails sans sortir, pour cela, du cadre de l'invention. Of course, the invention is not initiated. in the embodiment due which has just been described and shown, numerous modifications of details can be made without departing from the scope of the invention.
