DETAILED DESCRIPTION OF THE INVENTION

(18) With reference to FIGS. 1 to 10, number 1 generally indicates a helmet, in particular work or sports protective helmet, according to the present invention.

(19) The helmet 1 comprises a structure 2 having at least one convex outer surface 2a (FIGS. 1 to 3 and 5 to 7, 9 and 10) and at least one concave inner surface 2b (FIGS. 4 and 8) adapted to receive a user's head in engagement.

(20) As seen in FIGS. 1 to 9, the helmet 1 comprises two coupling and decoupling elements 3 for the engagement of at least an accessory 4 (FIGS. 5 to 9 and 11 to 15), preferably a face protection accessory 4, in particular a visor 4a (FIGS. 5 to 8), a mask 4b (FIG. 9), a net or similar accessory, each of which can be engaged on a lateral portion 2c of the outer surface 2a of structure 2.

(21) Each coupling and decoupling element 3 is advantageously removable from the helmet 1 and has a body 5, having at least one coupling mechanism 6 that allows the engagement and the disengagement of the above mentioned accessory 4 when the coupling and decoupling elements 3 are engaged thereto.

(22) As seen in FIGS. 12 to 15, each coupling and decoupling element 3 of accessory 4 comprises at least one attachment portion 7, which can be inserted in at least one respective attachment opening 8, obtained on the helmet 1.

(23) In detail, each attachment opening 8 obtained on the helmet 1 is obtained through a peripheral edge 2d, which is arranged near to the base 2e thereof.

(24) Preferably, each attachment opening 7 is obtained through the respective peripheral edge 2d of the helmet 1 and develops substantially parallel or tangential to the outer surface 2a thereof, so that the engagement of the respective coupling and decoupling element 3 for the accessory 4 is carried out along a direction substantially parallel or tangential to the outer surface 2a of helmet 1.

(25) The attachment portion 7 of each coupling and decoupling element 3 can be inserted in a snap-fit manner in the respective attachment opening 8 of helmet 1.

(26) The attachment portion 7 of each coupling and decoupling element 3 can be engaged by interference in the respective attachment opening 8 of helmet 1.

(27) Each attachment opening 8 of helmet 1 is substantially square-shaped, preferably rectangular, and the attachment portion 7 of each coupling and decoupling element 3 is substantially plate-shaped with a substantially square-shaped section, preferably rectangular.

(28) As seen in FIGS. 11 to 13, the attachment portion 7 of each coupling and decoupling element 3 extends cantilevered from the body 5 of the latter.

(29) Preferably, the attachment portion 7 of each coupling and decoupling element 3 tapers away from the body 5 of the latter and ends with an enlarged end 7a defining at least one abutment tooth for coupling with a respective abutment edge 8a (FIG. 4) of the respective attachment opening 8 arranged inside the helmet 1.

(30) The attachment portion 7 of each coupling and decoupling element 3 is advantageously elastically deformable, at least transversely with respect to its longitudinal extension, in order to guarantee its snap-fit engagement in the respective attachment opening 8 of helmet 1 and the disengagement from the same.

(31) In detail, when each coupling and decoupling element 3 is applied on the helmet 1, the respective attachment portion 7 is inserted in the respective attachment opening 8 of the helmet 1. During the insertion, the enlarged end 7a of the respective attachment portion intercepts the inner wall of the respective attachment opening 8a, slightly bending the latter towards the opposite wall. Once the enlarged end 7a of the respective attachment portion 7 goes beyond the inner abutment edge 8a of the respective attachment opening 8, the attachment portion 7 assumes its own original orientation by coupling to the respective abutment edge 8a.

(32) The disengagement of the attachment portion 7 of the respective coupling and decoupling element 3 from the attachment opening 8 of the corresponding helmet 1 can be carried out easily by acting manually on the respective enlarged end 7a. In this case, the attachment portion 7 bends as much as to allow the respective enlarged end 7a to fit inside the respective attachment opening 8, enabling the attachment portion 7 to slip off from the latter.

(33) The above mentioned coupling mechanism 6 of each coupling and decoupling element 3 for coupling and decoupling the face protection accessory 4 comprises at least an engagement portion 9 projecting from the respective body 5 transversely with respect to the main development of the respective attachment portion 7.

(34) The engagement portion 9 of the coupling mechanism 6 of each coupling and decoupling element 3 is shaped so as to receive a respective engagement portion 10 of each accessory 4 in engagement whereon an engagement seat 10a is obtained, at least partially counter-shaped with respect to the engagement portion 9.

(35) In order to allow the relative rotation between the accessory 4 and the helmet 1 on which it is mounted, the engagement portion 9 of the coupling mechanism 6 of each coupling and decoupling element 3 is substantially cylindrical and the engagement seat 10a of the respective engagement portion 10 of the accessory 4 is defined by a circle-shaped through opening.

(36) Going into further detail, the coupling mechanism 6 of each coupling and decoupling element 3 comprises at least one fixed coupling abutment 11 which projects in a transversal manner from the respective engagement portion 9 of the coupling mechanism itself. When the engagement portion 10 of the accessory 4 is mounted on the respective coupling element 3, it rests between the respective fixed abutment 11 and the respective body 5 of the latter.

(37) The coupling mechanism 6 of each coupling and decoupling element 3 further comprises at least one movable coupling abutment 12 transversely projecting from the respective engagement portion 9 on the opposite side with respect to the fixed coupling abutment 11 of the same coupling mechanism 6.

(38) Advantageously, the movable coupling abutment 12 of the coupling mechanism 6 of each coupling and decoupling element 3 is switchable between a first position, in which it projects at least partially from the engagement portion 9 of the respective coupling mechanism 6 in order to hold the respective engagement portion 10 of an accessory 4 when the latter is mounted on the respective coupling and decoupling element 3, and a second position, in which it does not project from the engagement portion 9 of the respective coupling mechanism 6 allowing the application of an accessory 4 on the respective coupling and decoupling element 3 or the removal of the same from the respective coupling or decoupling element 3.

(39) The movable coupling abutment 12 of the coupling mechanism 6 of each coupling and decoupling element 3 is operatively associated with elastic return means 13, preferably at least one helical spring 13a (FIG. 13) that maintains or returns the respective movable coupling abutment 12 to the first position, in the absence of forces capable of leading the latter towards the second position.

(40) Advantageously, the movable abutment element 12 has a profile, in longitudinal section (FIGS. 14 e 15), having a first inclined surface 12a tapering towards the body 5 of the respective coupling and decoupling element 3 away from the engagement portion 7 of the respective coupling mechanism 6. The first inclined surface 12a switches the respective movable coupling abutment 12 from the first to the second position when an engagement portion 10a of an accessory 4 is fitted on the respective engagement portion 9 of the respective coupling mechanism 6 of the respective coupling and decoupling element 3 and pushed towards the body 5 of the latter. In this case, the engagement portion 10 of the accessory 4 intercepts the first surface 12a of the movable coupling abutment 12 switching it from the first to the second position, whereby the engagement portion 10 of the accessory 4 can assume the correct resting position on the engagement portion 9 of the respective coupling and decoupling element 3. Once the engagement portion 10 of the accessory is fitted on the engagement portion 9 of the respective coupling and decoupling element 3, the movable coupling abutment, free from counter forces, is brought by the elastic return means 13 from the second position to the first position, blocking the engagement portion 10 of the accessory mounted on the respective coupling and decoupling element 3.

(41) Still with reference to FIGS. 14 and 15, the movable abutment element 12 has a profile, in longitudinal section, also having a second inclined surface 12b, transversal to the first one 12a, tapering from the body 5 of the respective coupling and decoupling element 3 away from the respective engagement portion 9 of the respective coupling mechanism 6. The second inclined surface 12b switches the respective movable coupling abutment 12 from the first to the second position when an engagement portion 10 of an accessory 4, fitted on the respective engagement portion 9 of the respective coupling mechanism 6 of the respective coupling and decoupling element 3, is pulled away from the body 5 of the respective one of the latter.

(42) Preferably, the inclination of the second surface 12b of the movable coupling abutment 3 is greater than the inclination of the first surface 12a, such as to requirein order to switch the latter from the first position to the second positiona force greater than the force required for performing such switching by acting on the first surface 12a of the movable coupling abutment 12.

(43) The application, by pushing, of an accessory 4 on the coupling and decoupling elements 3 is easier than the removal, by tearing, of the accessory 4 from the coupling and decoupling elements 3.

(44) In order to allow the manual switching of the movable coupling abutment 12 of the coupling mechanism 6 of each coupling and decoupling element 3, the movable coupling abutment 12 comprises at least one gripping portion 12c, which projects in a transversal manner with respect to the main development of the movable coupling abutment itself.

(45) As seen in FIGS. 11 and 12, the body 5 of each coupling and decoupling element 3 is also provided with an arched portion 14, which substantially reproduces a portion of the profile of the engagement portion 9 of the respective coupling mechanism 6.

(46) The arched portion 14 has a resting edge 14a on which a resting pin (not visible in the appended figure) slides, which pin projects from the respective engagement portion 10 of an accessory mounted on the helmet 1 when lifting or lowering the latter.

(47) The resting edge 14a is advantageously provided with at least two concavities 14b, which correspond to the lifted and the lowered position of the accessory 4.

(48) Advantageously, the engagement portion 10 of the accessory 4 and/or the resting pin of the same are elastically deformable, so as to enable the displacement of the pin from a concavity 14b to the other during the ascent or the descent of the accessory 4.

(49) The helmet according to the present invention solves the problems observed in the known technique and achieves important advantages.

(50) Firstly, the coupling and decoupling elements provided on the helmet described above notably facilitate the application or removing operations of the face protection accessories, making said operations practical and easy to perform.

(51) Furthermore, the coupling and decoupling elements ensure a secure and firm connection between the helmet and the mounted accessory.

(52) It should also be added that the coupling and decoupling elements guide the ascent and the descent of the accessories mounted along a regular path, without any movement that is transversal to the ascent and the descent.

(53) It should also be noted that the ability of removing the coupling and decoupling elements from the helmet allows the maintenance thereof, when needed, or the substitution of the same with other identical or different coupling and decoupling elements.

(54) Lastly, it should be pointed out that the coupling and decoupling elements allow a face protection accessory to be promptly replaced with another different one having the same engagement portions.
