专利摘要:
The present sword comprises at least on one portion of its length and from its free end a longitudinal zone (7) of reduced cross-section and to which are concentrated the strains to which the blade is subjected and which is adapted, when the fatigue of the material of the blade may result in its transversal severing, to yield longitudinally by dividing the sword into two longitudinal fragments which indicates the state of fatigue of the metal. For a foil, the longitudinal breaking zone (7) is comprised of an axial web (2b) which, delimited by two deep longitudinal grooves (6) which open from the small faces of the blade and which give it an ''H'' cross-section, has a thickness (e2) which becomes thicker and thicker, proportionally to the increase of the sword cross-section, from the extremity of the sword to the end of said breaking zone (7).

专利说明:

The invention relates to sports equipment, in particular to fencing, and can be used in rapiers, swords and sabers, blades (blades) of which are made of treated steel, an alloy or not.
Under continuous blows, contact, two blades between themselves, as well as due to the strong stresses required from the blades during jumps, the composite metal is worked out and begins to break.
When a transverse rupture of the blade occurs because of a jump, the blade fragment, remaining in the swordsman’s hand, is a dangerous weapon with its warped end that can pierce the breastplate and damage the body of the enemy with the risk of death. hardening steel containing nickel and titanium in combination with molybdenum and cobalt or without them. Experience has shown that these blades are stronger and more durable, but there are cases with some The conditions of intensive use when the steel is broken transversely, as well as cnnaaii. Thus, the dispersion-hardening steel did not solve the problem completely.
The purpose of the invention is to increase the be-. safety in use by replacing a transverse fracture, especially dangerous, with a longitudinal fracture that is not dangerous for fencers

Rapier 1 (FIGURE 1-6) has a blade 2, the tip of which is extended by means of a tip with cutting 3, and on the load is extended by a barrel with cutting 4 with fixation on the hilt o This blade has a cross section 5, usually rectangular,
According to the invention, the blade contains two longitudinal deep grooves 6, extending on the small sides of the blade and giving it a cross-section H-shape, toe formed by two wings 2a, connected by a central part 2
More precisely, two parallel days-: the conductor 6a of the grooves 6 form among themselves in the rupture zone 7 a zone of stress concentration, corresponding to the central part of the 2H H-shaped cross section
Each of the bottoms 6a is connected to the corresponding side 6b by rounded transitions 8
As shown in Fig. 2-5, at the reference distance 1 from the edge 9 of the blade, mainly to the middle 10, its grooves have a depth p p, which significantly increases in proportion to the size increase T, - I),

so that the channel 2b has a thickness e in zone 7, is increased and is proportional to the increase in the cross section, in order to ensure constant strength over this length
In addition, the grooves () have a constant depth and will give the central part 2b a thickness L, which increases in the direction of the nozzle.
When this blade is used, continuous shocks and stresses with alternation of squeezes and expansions, acting on the wing of the section of the H-shaped fory, extend to the whole length of the central part 2b. 7, which, due to a decrease in thickness, gets tired first. ,

mi, and longitudinally along parts of the length of the blade, and is characterized by a longitudinal crack that separates the two wings of an H-shaped section
This breaking violates the strength and elasticity of the blade, and also changes the sound of shocks and is a signal to replace the blade with
These grooves form a longitudinal zone 7, which, to the stress center, not only opposes the transverse damage of the blade, which is dangerous, but also converts this: the damage transversely and give a signal to the fencer to replace the blade.
The fig depicts the form of execution when the grooves 6 are provided with inclined side edges 6b facing the outside, giving them a cross section in the form of a trapezium, where the smallest base forms the hole 6c extending from the blade. From-: the version 6c has a height h, which is smaller than the diameter of the shell 11a of the conductor 11, designed to be placed in the groove 6 in order to transfer the touch with the breastplate of the enemy during a duel with an electric rapier
As shown on the left side of the figure, the conductor is installed in the corresponding groove 6 by pressing the conductor in the direction of the bottom of the groove in such a way that its shell 11a deforms ELASTICALLY during the passage through the opening 6c.
When the conductor is located in the groove 6, the natural elasticity of the shell 11a gives it the initial size. As indicated on the right side of the figUb, the shell Pa interacts with the sloping edges of the 6b grooves and ensures that the conductor is in this groove, which eliminates the use of glue. Thanks to this device, the conductor 11 is conveniently located in the groove and cannot exit, even if the blade is subject to significant bends - With these bends, the conductor and its shell can move inside the groove 6 without interfering with this placement of the conductor in this groove or the conductor function itself.

The proposed # 1 method of locating a conductor makes it much easier. Replacing it, since it no longer requires complicated operations to remove a conductor that has become unusable with solvents and glued to a conductor.
The trapezoid groove can only be made on one side of the rapier,
 The sword, shown in FIGS. 7-13, is a sword of a known cross-sectional sample of a V-shape, forming outer strands 12, going from point 13 to nozzle 14, Pointer 13 is provided with a cutting tip 15, while 14 continued barrel 16 with cutting.
The proposed sword contains in one part of its length and in the middle of its length, as shown by the distance 1 from the edge of the sword, a longitudinal zone 17 of stress concentration and longitudinal rupture. This zone is located on the rear side between the outer face 12, constituting this side, and the bottom 18a of the groove 18, which extends into the recess of the transverse V-section of the sword. In part of the blade length, the depth p, of the groove 18 increases shown in FIGS. 12 and 13 from the edges of the blade 13 and proportional to the change in the dimensions T and D of the cross section of this blade
VIA about
From this it follows that the longitudinal rupture zone 17 has a thickness e which increases from the tip of the blade to the end of the longitudinal zone 7o. Outside this zone and towards the nozzle 14, the groove 18a has a decreasing depth until its bottom reaches the level of deepening the profile Blades, as shown in FIG. 10, The zone of this alignment is located at a distance L from the end of the blade, a value higher than the distance lo. When the metal constituting the blade is in a fatigue stage to a degree that can cause a break in the blade, the fracture occurs. at the longitudinal direction in zone 17 is the concentration of stresses in the form of beams separating the two wings of a V-shaped cross section
In the case of a rapier, this kink leads to a change in the elastic characteristics of the blade, as well as sound when struck,
thereby, the swordsman should stop the fight and replace the blade.
The thickness of the longitudinal fracture zone 17 of the sword can also be controlled by processing the face 1 2 with or without a groove 18,
It should be noted that the thickness of the e "zone of the concentration of the voltage of the sword, as well as the thickness of the zone 7 of the concentration of the voltage of the rapier 2, is less than the thickness Z of each of the wings 12a, 2a ,. which it connects in such a way that the fracture zone is obvious. The grooves 6,18, making it possible to control the geometric characteristics of the stress concentration zone, can be made of any material from which the blades are made.
However, the execution is simpler, cheaper and faster in blades made of a dispersion-hardening alloy temporarily in a softened state, Te when the material is in a state of strong plasticity and weak hardness, and after making grooves 6 and other types of metal working; the blade is in a state of solidification by raising the temperature
In variants (FIGS. 14 and 15), the central part of the rapier 2 has holes in the part that corresponds to the zone of longitudinal rupture. 7 Openings 19 round shapes (FIG. 14) or oblong holes 20 (Fig 15) are evenly or unevenly distributed. They form bridges 21-22 alloy corresponding, which increase the stress concentration and form the kink i,
The oblong holes 20 are inclined between 30 and 60 with respect to the longitudinal axis of the rapier, separated by bridges in such a way that the leading edge of each hole is located either in front, or at least at the level of the back edge of the preceding perforation.
According to the unrepresented version, they can also be arranged in a staggered order from one and the other side of the longitudinal axis of the central part of the blade channel, and always parallel to this axis.
7160
The transverse size of each hole less than 1 mm n is about several tenths of a millimeter.
As shown in FIG. 12 and 3, similar perforations 19 and 20 can be made in the zone 17 of longitudinal rupture of a sword with or without a groove 18.
In embodiments, it was indicated that the longitudinal rupture zone extends over half the length of the blade, but it is obvious that this distance is given solely as an example and it can be from one third to two thirds of the length or even more depending on characteristics of the blade material, and this material can be steel or forging alloy, but also a composite material
