FIELD OF THE INVENTION
The present invention is related to a sports equipment of the type including a handle to which a stem is fixed.
STATE OF THE PRIOR ART
Foil, swords and sabres are known in the art as sports equipments used in competition between two contenders. Such equipments are normally light so as to enable a quick and accurate movement: their weigh is usually comprised between 500 and 700 grams distributed in an almost balanced fashion between the handle and the stem.
U.S. Pat. No. 660,692 shows a dump-bell which, in a use configuration, has a handling part from which a rigid threaded stem projects. The handle can be used as a conventional dump-bell or as a club for juggling exercises.
U.S. Pat. No. 5,180,164 discloses a light police baton with a handle to which a stick made up of a light rattan core is fixed. The baton is intended to be used by law enforcement officers to deliver minor damages to the ill-intentioned thanks to its overall lightness.
There arises the need for a sports equipment capable of enabling training individually or in pairs based on simulation of the typical moves in a sword and shield battle though entirely harmless and with a weight high enough to enable efficient muscle building.
SUMMARY OF THE INVENTION
The object of the invention is to provide a sports equipment thus made.
According to the invention, this purpose is attained thanks to a sports equipment according to claim 1, i.e. comprising a handle having a first end and a second end, at least one stem made of soft and light material aligned to said handle and fixed at the first end, and in which the weight of the handle is considerably greater than that of the stem.
In addition, the invention provides for a sports kit made up of the sports equipment used alongside a shield which comprises a disc-shaped structure having an inner face to which a handle is fixed and an outer face provided with a soft material lining, in which the disc-shaped structure is suitable to fixedly or removably house one or more variable weight elements.
A sports training method in which the sports equipment and the shield can be used simultaneously is also described.
In particular, using the sports equipment and/or the shield according to the invention enables performing a sports activity aimed at making countless more or less complex movements (or combinations of movements), individually, in pairs or in groups, thanks to the greater weight of the handle of the equipment and the structure of the shield (if provided), performing a physical training exercise for building up muscles and simultaneously, thanks to the soft and light stem of the sports equipment, making the action against an object (or person) entirely harmless.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows the principles of the invention with reference to an elementary object made up of an extended stem and a head in two different use configurations. In particular, the distribution of masses in the two different configurations with respect to the part in which the object is held by a user, are represented schematically. In FIG. 1.1 the mass stem m serves as a handle and the mass head M is moved at speed v. In FIG. 1.2 the mass stem m is moved at speed v and the mass head M serves as a handle. In cases where the mass M of the head is considerably greater than the mass of the stem (i.e. M>>m), the amount of motion P1=Mv associated to the mass head M of the object in the use configuration of FIG. 1.1 will be considerably greater than the amount of motion p2=mv associated to the mass stem m of the object in the use configuration of FIG. 1.2; i.e. P1>>p2. This implies that an object impacted by the head M moving at speed v would receive a stress (force) considerably greater than the stress exerted by the mass stem m which moves at the same speed v. Vice versa, an object impacted by the mass stem m moving at speed v would receive a stress (force) considerably lower than the stress exerted by the mass head M which moves at the same speed v.
FIG. 2 illustrates a conventional hammer (FIG. 2.1) and a conventional sword (FIGS. 2.2) and three embodiments of the invention (FIGS. 2.3, 2.4, 2.5) with the aim of revealing the physics principle described with reference to FIG. 1.
The hammer illustrated in FIG. 2.1 has a head T with considerably greater mass with respect to the handle im. Also the sword in FIG. 2.2 has a blade L with a considerably greater mass with respect to the handle ip. With the aim of optimising the purpose that these objects were designed for, it is actually preferable that the amount of motion transmitted to the object to be impacted by means of the opposite end with respect to handle be the greatest possible (same principle also applying to a baseball bat, golf club or the like).
On the contrary, the article of the example illustrated in FIG. 1.2 refers to a sports equipment A according to the invention, which is shown in some embodiments thereof in FIGS. 2.3-2.11 in which the equipment A has a handle i having a considerably greater mass than the mass of the stem s. Thus, the amount of motion transmitted to the object or person hit by the stem s is reduced to the minimum and, at the same time, due to the heavy handle i, a user may perform a considerable physical exercise suitable to build muscles and improve strength, resistance and coordination physical performance.
In an embodiment, the weight of said handle i is one order of magnitude greater than that of the stem s.
With reference to the centre of mass of the sports equipment A according to the invention, it is at a point comprised between the first end 1 and the second end 2 of the handle i.
The heavy handle i is designed to enable a comfortable and firm grip with one hand or, in an embodiment, with two hands. In addition, it can be variously shaped: in FIG. 2.3 the handle i is shaped to form a constant radius cylinder, while in FIGS. 2.4, 2.5, 2.6 and 2.7 it has one or two disc-shaped elements or flanges 3 projecting from one or both ends 1, 2. Like in the weight-lifting handles, the projecting disc-shaped elements 3 have the double function of increasing the weight of the element on which they are mounted and protecting the hand when the element is placed on the ground. In order to make gripping further harmless in case of impact, in FIG. 2.8 the flange projecting from the end 2 is shaped without edges and in FIGS. 2.10 and 2.11 the end 2 is provided with a soft lining 13. The diameter of the handle i is comprised between 10 and 60 mm, more preferably approximately between 30 and 40 mm. The weight of the handle i may be comprised approximately between 1 kg and 10 kg.
The stem s is designed to be as light as possible, so that the amount of motion transmitted during an impact is minimum. In addition, it is made of soft material, so that the force resulting from the impact is minimised further. An example of material suitable for constructing the stem is XL EXTRALIGHT®, a closed-cell expanded material sold in Italy by Finproject S.p.A. Thanks to these characteristics, the action of the sports equipment A on an hit object or person will be of low impact and thus entirely harmless.
In the preferred embodiment, the stem s, in the area for coupling with the handle, has a protection-like flange 9 covered with soft material to partly protect the hand of a user and prevent the hit object or person from impacting against a part made of hard material.
The length of the stem s is approximately comprised between 20 and 100 cm, more preferably between 30 and 80 cm; as mentioned, the weight of the stem s is considerably lesser than that of the handle i and preferably lesser than 1 Kg approximately. The heavy handle i and the light stem s are aligned on the same axis and are integrally mutually joined so as not to disengage during use. In some embodiments, the engagement between the stem s and the handle i is permanent, while it is releasable in others so as to enable disassembly thereof.
In an embodiment, the stem s is constituted by an inflatable bladder.
FIG. 3 shows some embodiments of the equipment A according to the invention.
In FIG. 3.1, the fixing of the stem s on the handle i is obtained by gluing or coupling so as to obtain the assembled equipment A of FIG. 3.2;

Screw-like fastening members v are designed to fix the end of the portion of the pipe t projecting from the stem s to the second end 2 of the handle 1 so as to obtain the assembly A of FIG. 3.8.
In the embodiments shown in FIG. 3 the handle can be constituted by a cylinder made of plastic and/or rubber material with end flanges 3 within which one or more suitably calibrated weights (for example made of iron or lead) can be permanently or removably housed. Alternatively, the handle i and the flange 3 can be made of one or more heavy materials (for example iron or lead) and be partly or fully covered by soft material.
