Description

The present invention relates to a mounting vice of artificial flies

  for fishing with a progressive regulator of the pressure of the jaws of the vise.

  Clamping the jaws of an artificial fly mounting vice is usually done by means of a lever, a nut or a screw by which the user exerts or releases pressure to close, to open the jaws of the vise. A lack of tightening prevents the hook from holding well in the jaws of the vise while an excess will damage more or less short time the jaws of the vise when it is not the hooks themselves which would be irremediably weakened by an excess of tightening. This defect is encouraged by the user who instinctively i o tightens to make it better, by the manufacturer who sets the pressure of the jaws exaggerated for the same purpose.

  The device according to the invention overcomes this disadvantage. It comprises in fact a spring or a set of elements making office, placed between the clamping lever (or the screw or the nut making office) and the jaws of the vise or their support, so 15. to ensure progressive tightening whose power limits are a function of the pressure exerted on the uncompressed spring and compressed within the limits of action of the clamping lever. In this way, the minimum and maximum clamping forces are determined in advance, according to a setting previously made and it is then possible to use extra fine, fragile jaws without taking the risk of damaging them by an excess o 2 of pressure while maintaining regularity and efficiency of the tightening of the hook in the jaws of the vise. Compared to conventional vices, the user will be pleasantly surprised by the smooth operation, the ease of use and the reliability of the device according to the invention. Another advantage, the greater the iron diameter of the hook, the greater the pressure exerted on them is great for the same setting of the jaws, the vice provided with the device according to the invention adapting in a way of itself the pressure of the jaws to the size of the hook thanks to the progressive action of the spring. It should be noted here that the device according to the present invention adapts equally well to the vices whose pressure exerted on the lever tightens or loosens the jaws of the vice, whether the vice is fixed or rotary. About the spring system, a 3 o spring buffer in ELADIP, registered trademark plastic material, is a choice of spring adapted for this purpose, another may be for example a set of spring washers, which allows depending on the number and the force of the washers chosen to properly adjust the amplitude and the force exerted on the clamping lever of the jaws. It should be noted here that the addition of a simple spring according to the invention adapting to a conventional vice transforms it into a vice according to the invention.

  According to a preferred embodiment, the spring consists of an ELADIP spring pad, registered trademark plastic material, or better for this model, a set of spring washers interposed between the lever, the screw or the nut. clamping the jaws and the jaws themselves or their support. The pressure exerted on the lever by the user thus gradually tightens the jaws of the vise.

  According to one variant, the lever actuating the progressive compression of the spring, and therefore of the jaws of the vice, is connected to a fixed point. The pressure exerted on the lever releases all or part of the prior compression of the jaws of the vise and thus causes their opening.

  According to a second variant, the vice according to the invention is a rotary vice. According to a third variant, a kit of spare parts comprises at least the spring according to the invention which converts a conventional vice into a vise according to the invention.

  According to a fourth variant, the spring transforming a conventional vice into a vice according to the present invention is placed inside or around the rod supporting the jaws of the vice or inside a piece interposed between the lever and the bits. Any pressure exerted by the lever on the spring compresses gradually, which has the effect of tightening just as gradually the jaws of the vise. The opening of the jaws is done by releasing the pressure on the spring using the lever.

  The attached drawings illustrate the invention: FIG. 1 represents an example of a vice according to the present invention equipped with a set of spring washers or an ELADIP spring buffer and whose pressure exerted on the clamping lever gradually tightens the jaws of the vice and is adjusted by a nut.

  FIG. 2 represents an exemplary vise according to the present invention equipped with a set of spring washers or a spring buffer and whose pressure exerted on the clamping lever progressively loosens the jaws of the vice.

  Figure 3 shows another example of vice according to the present invention, rotary in this case, the pressure exerted on the clamping lever gradually tightens the jaws of the vice and is adjusted by a screw.

  FIG. 4 is a sectional view of a rotary vice according to the present invention, the pressure exerted on the clamping lever gradually tightening the jaws of the vice, the 2o spring being housed inside the rod supporting the jaws of the vice.

  FIG. 5 shows a rotary vise according to the present invention, the pressure exerted on the clamping lever inserted with a buffer spring between the jaws of the vise, at their base, tightens the jaws of the vise.

  The vice shown life-size in Figure 1 comprises a clamping lever (1) 2s articulated on the rod (2) of the jaws (3) of the vice, a spring (4) consisting of a set of washers spring or buffer spring and an adjusting nut (5) of the jaws (3) of the vise. The length of the lever (1) and the position of the spring (4) relative to the articulation at the movable end (M) of the shank (2) of the jaws (3) of the vice are such that a pressure measurement exerted by the user on the lever (1) is multiplied and allows 3D to gradually tighten the jaws (4) of the vice, proportionally to the force of the pressure exerted by the user on the clamping lever (1) .

  In the embodiment according to FIG. 2, the clamping lever (1) bears on a fixed point (F) integral with the support (S) of the jaws (3) of the vice, and is connected to the rod ( 2) jaws (3) of the vice at a moving point (M). The pressure exerted by the spring (4) 35 permanently tightens the jaws (3) of the vice with the pressure force chosen by the user by means of the adjusting nut (5). When the user exerts a progressive pressure on the lever (1), the spring (4) crushes gradually, releasing the pressure exerted on the jaws (3) of the vise until they ' open sufficiently at the discretion of the user.

  In the embodiment of FIG. 3, the vice according to the invention comprises a clamping lever (1) articulated on the stem (2) of the jaws (3) of the vice, a spring (4) consisting of a set of spring washers or a spring buffer and a set screw (5) of the jaws (3) of the vise. The nut (6) for locking the tube (7) housing the jaws (3) of the vise allows, once unlocked, the rotation of the tube (7) and consequently, that of 4 h jaws (3) of the vise. Once tightened, the nut (6) blocks the tube (7) in the position chosen by the user.

  The vice shown in section in Figure 4 comprises a clamping lever (1) articulated on the frame (2) in which are housed the jaws (3) of the vise. A spring (4) constituted by a spring buffer (4) is housed inside the rod (5) of the jaws (3) of the vice and a cylinder (6) interposed between the lever (1). ) and the spring (4). Any pressure exerted gradually on the lever (1) is transmitted to the cylinder (6) which causes the spring (4) to close the jaws (3) of the vise by the pressure it exerts on them (3). The vice shown in Figure 5 comprises a lever (1) interposed between the jaws (3) of the vice at their bases (5 and 6). A spring (4) constituted by a spring buffer (4) is placed between the lever (1) and the base (5 or 6) of one of the jaws (3) of the vice.
