Accessory for securing points d'arret on fencing épées

Abstract

The invention relates to an accessory for securing points darrt on fencing pes, comprising a screw for securing the point darrt which is located on the tip of a fencing pe, in order to close the circuit of the electric touch-detection device with which said swords are equipped. The invention includes a screw-coupling tool, characterised in that the screw includes a central axially-extending through-hole having a hexagonal or any other prism-shaped configuration, while the actuation end of the tool includes a first cylindrical or frustoconical segment so that it can be easily fitted to the hole in the screw. In addition, a collar is provided half-way along the length or height of the screw, which serves as an end-stop element.

Claims

1. Accessory for securing stopping points on fencing swords, which has a screw for securing a stopping point that is situated on a point of a fencing sword, with the purpose of closing a circuit of an electric device for detecting touches that said swords incorporate, said accessory comprising: a screw with an external threaded surface longitudinally extending from a distal end to a proximal end of said screw, a through-hole in an axial and longitudinal direction of said screw and a distal transversal flat slot located at said distal end and a proximal transversal flat slot located at said proximal end, a collar provided on said external threaded surface halfway between the distal and proximal ends of said screw and configured to act as a stop against a metallic body of the stopping points of the fencing swords when tightening said screw; and a tool for actuating said screw having a proximal end with a handle extending perpendicular to a length of said tool and an actuating distal end with a flat surface perpendicular to the length of said tool, wherein a first inserting section having a uniform cross-section perpendicularly extends away from said flat surface and a second inserting section, having a diameter equal to or smaller than a diameter of said first inserting section, longitudinally and coaxially extends away from a distal end of said first inserting section and a flat section that transversally extends away from an exterior surface of only said first inserting section and configured to complementary mate with the transversal flat slots of said distal and proximal ends of said screw, wherein the first and the second inserting sections are inserted into said through-hole when said screw is actuated.

2. The accessory of claim 1, wherein the shape of the first inserting section of said tool is configured to complementary mate with the shape of the through-hole of said screw.

3. The accessory of claim 1, wherein said through-hole and said first inserting section have a hexagonal shape.

4. The accessory of claim 1, wherein said second inserting section has a cylindrical or truncated conical shape.

Description

DESCRIPTION OF THE DRAWINGS

(1) To complement the description carried out and with the object of aiding a better understanding of the characteristics of the invention, according to an example of a practical preferred embodiment thereof, a set of drawings accompany as an integrated part of said description in which, with an illustrative and non-limiting character, the following has been represented:

(2) FIG. 1.Shows a side elevation view of the screw that forms part of the accessory carried out according to the object of the present invention.

(3) FIG. 2.Shows a frontal elevation view of the screw represented in the previous figure.

(4) FIG. 3.Shows a perspective view of the screwdriver embodying the tool, as part of the accessory object of the invention.

PREFERRED EMBODIMENT OF THE INVENTION

(5) As may be seen in the aforementioned figures, the accessory of the invention comprises a screw (1) having an external threaded surface (1s) longitudinally extending between a distal end (1d) and a proximal end (1p) of the screw (1) and a tool (8) to actuate the same, a screw (1) that is provided with a hole or hexagonal passage (2), which is axial and longitudinal, whilst each end have a transversal slot (3), all of this in such a way that two sections that are delimited by an intermediate collar (4), which is provided on the external threaded surface (1s) halfway along the length between the distal end (1d) and proximal end (1p) of said screw (1), are established on the screw, in such a way that the screw constituted in this way may be actuated by a tool that may be embodied as a screwdriver with a hexagonal head for its insertion into the hole (2) and actuate the corresponding screw (1), equally being possible its actuation by the same tool (8) that has, before the hexagonal section (5) of such a tool (8), a flat section (6) determining a screwdriver, which makes it possible to actuate the screw via the tool or screwdriver (2) by means of the hexagonal (5) and flat (6) sections that have just been mentioned.

(6) The end of the tool (8) ends via a cylindrical section (7) with a diameter significantly smaller or equal to that of the passage of the hexagonal tool (5) section that helps the correct positioning of the assembly. This cylindrical section (7) may have a truncated cone configuration for greater ability in the moment of inserting the tool assembly into the screw (1) hole.

(7) For its part, the intermediate collar (4) acts as a stop in the tightening of the screw (1) to carry out the securing of the stopping point in a fencing sword, all of this in such a way that the screw (1) in question supports the use of the aforementioned manual tool (8) and with a mixed configuration, i.e., with a hexagonal section (5) for hexagonal openings (2) and a flat section (6) for the transversal and flat slots (3) intended at the ends.

(8) When the aforementioned tool (8) is actuated on the screw (1) it distributes the force of the tightening torque applied while adjusting the screw (1), in a balanced and safe way for the integrity of said screw, with the particular feature that the collar (4) that acts as a stop avoids the undesired effects of over-tightening on the stopping point that is being secured.

(9) The screw (1) hole (2) may be cylindrical, square or any other prismatic configuration, this being complementary to the tool in FIG. 3 with regard to the section (5).

(10) In addition to the aforementioned advantages, i.e., the high efficiency in the transmission of the tightening tool torque on the screw, in a balanced and distributed way along its entire length, it is also possible that the screw itself suffers less wear when it comes to being placed and that it lasts longer than the conventional ones.
