Description

[0001] ZIPPER

[0002] The present invention relates to a zipper and an end-stop device for said zipper.

[0003] The present invention finds preferred and main application in the clothing sector, preferably in the manufacture of fasteners for openable garments such as sweaters, sweatshirts or jackets.

[0004] In the prior art, such garments, in a wide variety of shapes and fabrics, are alternatively made with button fastenings or by means of zippers of the divisible or separable type.

[0005] In other words, in order to allow the complete separation between the two zipper elements, the zipper has an end-stop device split into two components, one (box) constrained to the first zipper element along which the slider slides and the other (pin) constrained to the other zipper element. Usually, in order to couple the two parts together, it is necessary to insert the pin longitudinally, i.e. along the sliding direction of the slider, first inside the slider and then inside the box, which is provided with a side notch for this purpose.

[0006] This operation therefore requires the use of both hands by the user, who must take care to keep the slider in contact with the box with one hand and insert the pin with the other.

[0007] In most cases, this is not particularly complex, but there are situations in which using both hands and inserting the pin into the slider and / or box can be difficult.

[0008] Whenever a hand is occupied by an object, it becomes necessary to disengage the object, which is not always easy; moreover, in particular cases, for example during movement or when the hands are covered with gloves, the reduced dexterity can make the operation not very smooth, leading to unwelcome loss of time. But not only that, the inability to use the second hand could also be a permanent or semi-permanent condition, making it very difficult to zip up a jacket or sweatshirt for those in this situation.

[0009] In this regard, there are a number of solutions that aim to simplify the coupling operation between the two zipper elements, one of which is shown in patent publication EP3245891 ; this solution overcomes the need to couple the pin and box longitudinally by introducing the possibility of constraining the two components of the end-stop device transversely, i.e. by superimposing them starting from an angularly offset position and guiding, by means of a suitably shaped profile, a relative rotation between the components that brings them into alignment.

[0010] Disadvantageously, this solution only partially addresses and solves the above-mentioned problem, as it is still necessary to arrange the two zipper elements at a predetermined orientation, which is not at all easy without the use of two hands.

[0011] However, this solution does not obviate the need to first position the slider in the end-of-stroke position.

[0012] The aim of the present invention, therefore, is to provide a zipper and an end-stop device for said zipper that obviates the drawbacks of the above- mentioned prior art.

[0013] In particular, it is the aim of the present invention to provide a zipper and an end-stop device for said zipper that can be easily closed with one hand. Furthermore, it is also an aim of the present invention to provide an efficient and reliable zipper and end-stop device for said zipper.

[0014] These aims are achieved by a zipper and an end-stop device for said zipper having the characteristics listed in the following claims.

[0015] In particular, the zipper comprises a first zipper element extending along a first longitudinal axis and a second zipper element extending along a second longitudinal axis.

[0016] Preferably, the first and second zipper elements are selectively movable between a disengaged configuration and a coupled configuration, wherein the first and the second longitudinal axis are parallel to each other and define a zipper plane .

[0017] An end-stop device is connected to the first and second zipper element.

[0018] A slider is slidably associated with the first zipper element to move along the first longitudinal axis closer to and away from an end-of-stroke position, wherein it abuts against the end-stop device.

[0019] Preferably, an end-stop device is provided.

[0020] Preferably, the end-stop device comprises a first component connected to the first zipper element and a second component connected to the second zipper element.

[0021] Preferably, the second component is selectively coupled with the first component along a coupling direction transverse to said zipper plane.

[0022] Preferably, the end-stop device comprises a holding device associated with the first and / or second component.

[0023] Preferably, it is selectively switchable between a first configuration, in which it holds the slider in the end-of-stroke position and a second configuration, in which it holds the second component coupled to the first component by releasing the slider.

[0024] Advantageously, this system ensures that the slider is positioned at the stroke end when the two zipper elements are released, releasing it only when the first and second components are coupled.

[0025] This allows the two components to be coupled and the zipper to be closed with one hand under any circumstances.

[0026] Preferably, the transition from the disengaged configuration to the coupled configuration of the first and second zipper element is determined by the transition of the holding device from the first configuration to the second configuration, and vice versa.

[0027] More preferably, the holding device is configured to switch from the first to the second configuration during a coupling between the first and second component along the coupling direction.

[0028] In other words, when the first and second components are completely decoupled, the holding device is in the first configuration.

[0029] When the first and second components are fully coupled, the holding device is in the second configuration.

[0030] During coupling, switching from the first to the second configuration takes place.

[0031] In this configuration, the slider is released and can be moved along the first (and second) longitudinal direction to couple the two zipper elements. Furthermore, preferably, the holding device is configured to switch from the second to the first configuration when the slider reaches the end-of- stroke position.

[0032] Thus, when the slider returns to the end-of-stroke position, i.e. at the end of a return stroke in which the slider decouples the two zipper elements, preferably the holding device switches from the second configuration to the first.

[0033] In this way, the slider is held in the end-of-stroke position and the second component is released by decoupling from the first component.

[0034] Advantageously, the coupling and decoupling of the two zipper elements is reliable and repeatable under all circumstances.

[0035] Preferably, the first component of the end-stop device has a first base and a through-hole crossing the first base.

[0036] Preferably, the second component has a second base and a pin protruding transverse to said second base and insertable into said through-hole.

[0037] Preferably, moreover, the holding device comprises a first elastic element that is elastically movable between a first position, wherein it holds the slider in the end-of-stroke position and prevents it from sliding along the first longitudinal axis, and a second position, wherein it does not interfere with said sliding of the slider.

[0038] More preferably, in said first position, the first elastic element is coupled with the coupling portion of the slider.

[0039] Even more preferably, the first elastic element comprises an activation portion aligned with said through-hole of the first component along the coupling direction, wherein the protruding pin of the second component is configured to lift (or otherwise move) the first elastic element from the first position to the second position by acting in thrust on the activation portion during insertion into the through-hole.

[0040] Preferably, moreover, the holding device comprises a second elastic element that is elastically movable between a first position, in which it holds the second component coupled to the first component of the endstop device, and a second position, in which it does not interfere with a decoupling of the second component from the first component along the coupling direction.

[0041] More preferably, the second elastic element comprises at least one arm (preferably two) movable transverse to the coupling direction between the first and second position.

[0042] Thus, preferably the first elastic element is movable along the coupling direction, while the second elastic element is movable transverse to the coupling direction.

[0043] This slider includes a thrust element configured to move the arm from the first to the second position when the slider reaches the end-of-stroke position.

[0044] Preferably, the protruding pin of the second component comprises an enlarged head adapted to be inserted between said arms during the insertion into the through-hole of the first component and a restricted shaft defining two longitudinal grooves for accommodating the arms when they are in the approached position.

[0045] Preferably, the first and second elastic elements are made in a single piece in a single spring body.

[0046] These and other characteristics will become clearer from the following non-limiting example description of a preferred, therefore not exclusive, embodiment of a zipper and an end-stop device for a zipper as illustrated in the accompanying drawings, in which: - Figure 1 shows an exploded perspective view of a portion of a zipper according to the present invention;

[0047] - Figures 2a, 2b and 2c show, respectively, a perspective view with some parts removed, a longitudinal sectional view and a plan view with some parts removed of the portion of zipper in Figure 1 in a first configuration;

[0048] - Figures 3a, 3b and 3c show, respectively, a perspective view with some parts removed, a longitudinal sectional view and a plan view with some parts removed of the portion of zipper in Figure 1 in a second configuration;

[0049] - Figures 4a, 4b and 4c show, respectively, a perspective view with some parts removed, a longitudinal section view and a plan view with some parts removed of the portion of zipper in Figure 1 in a third configuration.

[0050] With reference to the accompanying figures, a zipper according to the present invention is indicated by the number 1 .

[0051] The zipper 1 thus comprises a first zipper element 2, a second zipper element 3, a slider 4 and an end-stop device 5.

[0052] The first zipper element 2 extends along a first longitudinal axis “A”.

[0053] The second zipper element 3 extends along a second longitudinal axis “B”. In use, the first 2 and second zipper element 3 are each attached (e.g. sewn) to an edge of a closable garment, e.g. a sweatshirt or jacket.

[0054] To allow selective opening of the garment by the user, the first 2 and second zipper element 3 are selectively movable between a disengaged and a coupled configuration.

[0055] In the disengaged configuration, the first “A” and the second longitudinal axis “B” are essentially skewed, while in the coupled configuration, the first “A” and the second longitudinal axis “B” are parallel to each other and define a zipper plane “C”.

[0056] In this regard, it should be noted that the expression “longitudinal axes” is intended in this text to define the prevailing extension direction of each zipper element, without necessarily implying that the elements must be straight or, even less, that they must have a rigid structure capable of maintaining a predetermined geometry when disengaged.

[0057] Each zipper element 2, 3 thus comprises a plurality of teeth 2a, 3a arranged in succession along their respective first “A” or second “B” longitudinal axis and configured to be coupled with each other.

[0058] The coupling and decoupling between teeth 2a, 3a is determined by the sliding of the slider 4.

[0059] The slider 4 is slidably associated with the first zipper element to move along the first longitudinal axis “A” closer to and away from an end-of- stroke position, wherein it abuts against the end-stop device 5.

[0060] The slider 4 comprises a main body 6 slidably associated with the first zipper element 2 and associated with the second zipper element 3.

[0061] The main body 6 is shaped to accommodate the teeth of the first 2 and second zipper element 3 during sliding, facilitating their coupling or decoupling depending on the sliding direction.

[0062] Preferably, the main body 6 of the slider 4 has two plates connected by a central septum.

[0063] This main body 6 has an abutment face 6a which, in the end-of-stroke position of the slider 4, abuts against the end-stop device 5.

[0064] The end-stop device 5 is in fact connected to the first 2 and the second zipper element 3.

[0065] According to an aspect of the invention, the end-stop device 5 comprises a first component 7, a second component 8 and a holding device 9.

[0066] The first component 7 is connected to the first zipper element 2. Thus, the abutment surface 6a of the main body 6 of the slider 4, in the end-of- stroke position, abuts on the first component 7.

[0067] The second component 8 is connected to the second zipper element 3 and is selectively coupled with the first component 7 along a coupling direction “D”, transverse to said zipper plane “C”.

[0068] In the preferred embodiment, the coupling direction “D” is orthogonal to the zipper plane “C”; the first 7 and the second component 8 are therefore coupled by overlapping and not longitudinal flanking.

[0069] The holding device 9 is associated with the first 7 and / or the second component 8.

[0070] Preferably, the holding device 9 is selectively switchable between a first configuration, in which it holds the slider 4 in the end-of-stroke position and a second configuration, in which it holds the second component 8 coupled to the first component 7 by releasing the slider 4.

[0071] Advantageously, the holding device thus configured enables the coupling and uncoupling of components 7, 8, as well as the sliding of the slider 4, reliably and immediately, without the need for the user to use both hands.

[0072] In fact, when the first 2 and the second zipper element 3 are in the disengaged configuration, the holding device 9 is in the first configuration, thus holding the slider 4 in the end-of-stroke position, not requiring the typical pulling action by the user to hold the slider in that position.

[0073] In this regard, the slider 4 comprises a hooking portion 6b configured to couple with the holding device 9 in the first configuration.

[0074] In this configuration, the first 7 and the second component 8 of the holding device 5 are decoupled from each other.

[0075] On the contrary, when the first 2 and the second zipper element 3 are in a coupled configuration, the first 7 and the second component 8 of the holding device 5 are coupled together and the holding device 9 is in the second configuration, avoiding decoupling (at least along the coupling direction “C”).

[0076] The transition from the disengaged configuration to the coupled configuration of the first 2 and second 3 zipper element is connected with the transition of the holding device 9 from the first configuration to the second configuration, and vice versa.

[0077] This holding device 9 is in fact configured to switch from the first to the second configuration during a coupling between the first 7 and the second component 8 along the coupling direction “D” and to switch from the second to the first configuration when the slider 4 reaches the end-of- stroke position.

[0078] Therefore, starting from the disengaged configuration of the zipper elements 2, 3, the first 7 and the second component 8 are coupled (with a relative movement) along the coupling direction “D”, as said transverse, preferably orthogonal, to the zipper plane “C”.

[0079] This coupling therefore takes place in the form of a clip and one hand is sufficient to press the first component 7 onto the second component 8.

[0080] It should be noted in this regard that, as illustrated in the exploded view of Figure 1 , a plate of the main body 6 which during coupling between the first 7 and the second component 8 is facing the second zipper element 3 has a notch 16 which allows the teeth of the second zipper element 3 to enter the slider 4 transversely (i.e. along the coupling direction “D”), flanking the teeth of the first zipper element 2.

[0081] At this point, the coupling of the first component 7 with second component 8 results in a switchover of the holding device 9 from the first to the second configuration.

[0082] In this way, the slider 4 is automatically released, free to slide along the first (or second “B”) longitudinal axis “A”.

[0083] At the same time, the first 7 and the second component 8 are kept coupled by the holding device 9.

[0084] In other words, the first 7 and the second component 8 of the end-stop device 5 are coupled to each other and no action is required on the part of the user to prevent their separation, while the slider 4 is disengaged from the end-stop device 5 by being able to slide to hold the first 2 and the second zipper element 3 to each other.

[0085] With one hand, therefore, the user can pull the slider 4 (preferably equipped with a pull tab) and bring it to hold the two zipper elements 2, 3. When opening the zipper 1 , the slider 4 is pushed towards the end-of- stroke position and, once it has reached it, it causes the transition of the holding device 9 from the second to the first configuration, i.e. involving the anchoring of the slider 4 to the end-stop device 5 and the simultaneous release / disengagement between the first 7 and the second component 8.

[0086] From a structural point of view, preferably the first component 7 of the endstop device 5 has a first base 10a and a through-hole 10b crossing the first base 10a.

[0087] More preferably, the first component 7 comprises a box-shaped body 10 which houses the holding device 9 and has said first base 10a and a sidewall 10c configured to abut against the abutment face 6a of the main body 6 of the slider 4.

[0088] The sidewall 10c is provided with a side opening 10d sized to accommodate the crossing hooking portion 6b of the slider 4.

[0089] This hooking portion 6b, therefore, protrudes (i.e., projects) from the main body 6, in particular from the abutment face 6a, along the first longitudinal axis “A”, so as to fit into the sidewall 10c when the end-of-stroke position is reached by the slider 4.

[0090] Preferably, the box-shaped body has a removable cover 10e opposing the first base 10a; this cover 10e delimits access to an internal compartment of the box-shaped body 10 in which the holding device 9 is inserted, allowing the assembly of the end-stop device 5.

[0091] In the illustrated embodiment, the box-shaped body 10 has a parallelepiped shape, with two bases (first base 10a and cover 10e) and a plurality of sidewalls 10c, one provided with the opening 10d.

[0092] The second component 8 of the end-stop device 5 has a second base 1 1 a and a protruding pin 1 1 b transverse to said second base 1 1 a.

[0093] The protruding pin 1 1 b can be inserted into said through-hole 10b of the first component 7.

[0094] In the preferred embodiment, the protruding pin 1 1 b has a head 1 1 c counter-shaped to the through-hole 10b.

[0095] Preferably, also, the second base 11 a has the same shape as the first base 10b. In the coupled configuration, the protruding pin 11 b of the second component 8 is inserted into the through-hole 10b of the first component 7, and the first base 10a is abuts (overlapping) on the second base 11 a.

[0096] It is therefore the insertion of the protruding pin 11 a of the second component 8 into the through-hole 10b of the first component 7 that determines the transition of the holding device 9 from the first to the second configuration.

[0097] Preferably, the holding device 9 comprises a first elastic element 12.

[0098] More preferably, the holding device 9 comprises the first 12 and a second elastic element 13.

[0099] The first elastic element 12 is elastically movable between a first position, in which it holds the slider 4 in the end-of-stroke position and prevents it from sliding along the first longitudinal axis “A”, and a second position, in which it does not interfere with said sliding of slider 4.

[0100] In the first position, therefore, the first elastic element 12 is coupled with the hooking portion 6b of the slider 4.

[0101] Preferably, the first elastic element 12 comprises an actuating portion 12a aligned with said through-hole 10b of the first component 7 along the coupling direction “D”.

[0102] In other words, the activation portion 12a faces the through-hole 10b so as to interfere with the protruding pin 11 b during insertion.

[0103] This protruding pin 11 b of the second component 8 is then configured to lift (or otherwise move) the first elastic element 12 from the first position to the second position by acting in thrust on the activation portion 12a.

[0104] The second elastic element 13 is elastically movable between a first position, in which it holds the second component 8 coupled to the first component 7 of the end-stop device 9, and a second position, in which it does not interfere with a decoupling of the second component 8 from the first component 7 along the coupling direction “D”.

[0105] Preferably, the first configuration of the holding device 9 has the first elastic element 12 in the first position and the second elastic element 13 in the second position.

[0106] In contrast, the second configuration of the holding device 9 has the first elastic element 12 in the second position and the second elastic element 13 in the first position.

[0107] Both the first 12 and the second elastic element 13 are preferably housed within the box-shaped body 10.

[0108] The second elastic element 13 comprises at least one arm 13a movable transverse to the coupling direction “D” between the first and second position.

[0109] Note that, preferably, the first elastic element 12 moves (or yields) along the coupling direction “D”, while the second elastic element 13 moves (or yields) transverse to the coupling direction “D”, preferably in a plane parallel to the zipper plane “C”.

[0110] Preferably, as illustrated in Figures 2 and 3, it is the slider 4 that determines the movement of the arm 13a between the first and second position.

[0111] In this regard, preferably the slider 4 includes a thrust element 6c configured to move the arm 13a from the first to the second position when the slider 4 reaches the end-of-stroke position.

[0112] The second elastic element 13 is therefore normally in the first position and, when the slider 4 is released from the first component 7 and slides, it tends to return to said first position.

[0113] Thus, when the first elastic element 12 is in the first position, releasing the slider 4 from the first component 7, the second elastic element 13 tends to return to its first position, pushing the slider 4 away from the end-of-stroke position. This advantageously guarantees the automation of the process, making it reliable and easily repeatable.

[0114] The thrust element 6c is preferably defined by a face of the hooking portion 6b inclined with respect to the first longitudinal axis “A”.

[0115] Preferably, therefore, the hooking portion 6b has at least a partly wedge- shaped (more preferably trapezoidal) conformation with at least one inclined face slidably associated, near the end-of-stroke position, with the second elastic element 13.

[0116] In the preferred embodiment, the second elastic element 13 comprises two arms 13a placed side by side in a plane orthogonal to the coupling direction “D” and movable closer to and away from each other between an approached position and a distanced position, corresponding respectively to the first and second positions of the second elastic element 13.

[0117] Note in this regard that, preferably, the protruding pin 11 b of the second component 8 comprises an enlarged head 11 c and a restricted shaft 11d, interposed between the enlarged head 11 c and the second base 11 a.

[0118] The enlarged head 11c is adapted to be inserted between said arms 13a during the insertion of the pin into the through-hole 10b of the first component 7.

[0119] The restricted shaft 11 c defines two longitudinal grooves 11 e to accommodate the arms 13a when they are in the approached position.

[0120] In the preferred embodiment, therefore, the protruding pin 11 b has a substantially “T” shape.

[0121] The enlarged head 11 c therefore defines, with the narrowed shaft 11d, a holding surface which, in the second position of the second elastic element 13, abuts against said arms 13a preventing decoupling between the first 7 and the second component 8.

[0122] It should be noted that, in certain embodiments, a single groove could be provided to accommodate a single arm 13a.

[0123] Preferably, moreover, the enlarged head 11 c has one or more inclined surfaces to facilitate crossing of the arms 13a during the insertion of the protruding pin 11 b into the through-hole 10b.

[0124] The inclined surfaces (or chamfers or guides) are therefore made on the extrados of the enlarged head 11 c.

[0125] With reference to the accompanying figures, preferably the first 12 and the second elastic element 13 are made in a single piece in a single spring body 14. Preferably, the spring body 14 is made of a suitably bent spring steel wire.

[0126] This spring body 14 is preferably held in place inside the box-shaped body 10 by the cover 10e, preferably provided with fixing protrusions.

[0127] This spring body 14 preferably comprises the two arms 13a elastically moving closer to and away from each other, placed side-by-side and coplanar to each other, each extending between a free end 14a and a pin area 14b,

[0128] In addition, the spring body comprises an eyelet portion 14c extending from the pin area 14b partially overlapping with the arms 13a.

[0129] The eyelet portion 14c having a transverse section 15a to said arms 13a shaped to couple with the hooking portion 6b of the slider 4 and an actuating portion 15b.

[0130] This actuating portion 15b, corresponding to the actuating portion 12a of the first elastic element 12, is operatively interposed between the pin areas 14b and the transverse segment 15a and incident with the protruding pin 11 b during its movement along the coupling direction “D”.

[0131] Preferably, the spring body 14 has an unloaded condition in which both the first elastic element 12 and the second elastic element 13 are in the first position.

[0132] In other words, both the first elastic element 12 and the second elastic element 13 are held in the second position by external factors: the protruding pin 11 b for the first elastic element 12 and the slider 4 for the second elastic element 13.

[0133] In their absence, they tend to return elastically to the first position.

[0134] The user is therefore able to implement the following method for fastening the zipper 1 :

[0135] - arranging the zipper 1 as described above, with the holding device 9 of the end-stop device 5 in the first configuration;

[0136] - coupling the second component 8 to the first component 7 of the endstop device 5 along the coupling direction D, so as to move the first elastic element 12 into the second position; - pushing, by means of the second elastic element 13, the slider 4 away from the end-of-stroke position, bringing said second elastic element 13 into the first position;

[0137] - holding the second component 8 coupled with the first component 7 by means of said second elastic element 13;

[0138] - translating the slider 4 away from the end-of-stroke position.

[0139] The invention achieves its intended purposes and obtains important advantages.

[0140] In fact, the provision of an end-stop device with cross-coupling (i.e. clipping) of the two components, and wherein both the end-of-stroke position of the slider and its release following coupling are guaranteed, makes it possible for the zipper to be fastened with one hand and without difficulty by the user.
