Description

ZIPPER (OPTIONS)

TECHNICAL FIELD OF THE INVENTION

This invention relates to a zipper.

BACKGROUND OF THE INVENTION

A zip fastener is traditionally considered to consist of a fastening chain formed by two rows of elements fixed along the edges of the respective fastening textile bands and configured to be connected or disconnected by a slider moving along the fastening chain in two directions, one for connecting, in another to separate two rows of elements.

It is known that the fastener element can be of several types: in the form of a spiral or zigzag, formed by folding into a spiral or zigzag of a continuous synthetic monofilament, fixed to a textile tape by weaving or sewing, or it has the form of an independent block of an individual shape, made of synthetic resin or plastic, applied to the tape by injection molding, or made of metal and fixed to the tape by wrapping and compressing the tape with the corresponding parts of the element. The vast majority of these types of fastener elements are fixed sequentially along the edge of the textile tape with a certain distance between the elements.

According to the structure, the fastener element can be conditionally divided into two main components: the first part is the base part, designed to fasten the element to the tape; the second part is the connection head, designed to create a reliable connection of the element with opposite elements. Most of the zippers in the world are made up of elements whose connection head is designed in such a way that only one level of connection of elements is created.

In the international application WO 2015/093338 A1 (Patent Document 1), containing the features of the restrictive part of paragraphs 1 and 6 of the claims of this of the invention, a zipper is described, which consists of a zipper chain formed by two rows of elements fixed to the edges of the respective tapes, and a slider capable of moving along the zipper chain in two directions, respectively connecting and disconnecting the rows of elements. Each fastener element has a base part for attaching to the tape and a connection head for connecting with opposite elements. The feature of the runner described in Patent Document 1 is that it is a vertical connection type runner, that is, the process of joining and separating elements of the two fastening tapes occurs in a direction perpendicular to the plane of the tapes.

In both embodiments of this invention, the zipper 1 comprises: a fastener chain 10 consisting of a first tape 11 and a second tape 12, as well as a first row of elements 15 formed by a plurality of elements, attached to the first tape 11, and formed by a plurality of elements of the second row of elements 16 attached to the second tape 12; and a slider 50a (according to the first embodiment of the present invention) or a slider 50b (according to the second embodiment of the present invention) configured to move along the first and second rows of elements 15 and 16 in two directions, one for connection and the other to separate the elements forming the first and second rows of elements 15 and 16.

Also in the following description, the direction in which the slider 50a or slider 50b moves to connect the first and second rows of elements 15 and 16 is referred to as the first direction, and the direction in which the slider 50a or slider 50b moves to separate the first and second rows of elements 15 and 16 is designated as the second direction. The first direction is opposite to the second direction. The first and second directions are also referred to as the top and bottom directions, respectively. The width direction of the fastener bands, which is horizontal in the plane of the bands 11 and 12 and perpendicular to the first and second directions, is referred to as the left direction and the right direction. The direction that is perpendicular to the placement plane of the fastener bands 11 and 12, which is defined by the first and second directions as well as the left and right directions, is referred to as the front direction and the rear direction. The side of the zipper 1 where the puller 62a (according to the first embodiment of the present invention) or the puller 62b (according to the second embodiment of the present invention) is located, which is fastened to the runner 50a or the runner 50b, respectively, is designated as the front surfaces, and the opposite side is designated as the rear surfaces.

The first and second tapes 11 and 12, which are part of the chain of the fastener 10, respectively have front surfaces 11a and 12a, as well as back surfaces 11b and 12b, where the front surfaces of both tapes 11a and 12a coincide in direction and are opposite to their rear surfaces 11b and 12b, and the rows of elements 15 and 16 are fastened respectively along the edge 13 of the first tape 11 and along the edge 14 of the second tape 12 in compliance with the specified distance between the elements, where the first row of elements 15 of the first tape 11 is located opposite the second row of elements 16 of the second tape 12.

Also, the zipper 1 has an upper stop 2 attached to the upper end of each of the rows of elements 15 and 16, and a lower stop 3 fixed to the lower ends of both rows of elements 15 and 16. These stops make it impossible for the slider 50a or the slider 50b to exit. beyond the upper and lower ends of the longitudinal rows of elements 15 and 16. Alternatively, in this invention, instead of the lower limiter 3, a detachable limiter with a socket, fixed at the lower end of one row of elements, and an insertion pin, fixed at the lower end of the other row of elements, can be used , which allows you to detach one zipper tape from another.

Next, the characteristics of the fastener element according to this invention will be considered in detail with the involvement of several examples of its alternative execution with reference to the corresponding drawings. The general characteristics of the fastener element according to this invention in any of the given examples of alternative execution are determined by the following set of properties: each of the elements of the zipper consists of a base part, fixed to the edge of the corresponding tape, and protruding from the base part of the connection head, formed by several links of coupling for connection with opposite elements; the connection head of each of the fastener elements is formed by the same number of clutch links; the clutch links of each of the elements are located sequentially one after the other in the direction of the opposite elements; the clutch links of each of the elements have the same configuration; each of the clutch links is formed by two sidewalls and two inclined surfaces; the clutch links of each of the elements, starting from the initial link of the clutch and ending with the final link of the clutch, are interconnected by a section of partial coincidence of their adjacent sidewalls; the clutch links of each of the elements are connected to the base part of the element by the sidewall of the initial link of the clutch; each link of the clutch of each of the elements has with the neighboring link of the clutch opposite directions of inclination relative to the plane of the tapes; each link of the clutch of each of the elements has with the neighboring link of the clutch equal in size angles of inclination relative to the plane of the tapes; the plane of the tapes passes through the middle of each link of the clutch of each of the elements; the plane of the tapes passes through the middle of the section, which each link of the clutch of each of the elements is connected to the adjacent link of the clutch; each clutch link has two oppositely directed clutch teeth formed by its ends protruding beyond the inclined surfaces of the adjacent clutch link; each clutch link has two oppositely directed clutch cavities formed by its inclined surfaces together with its own clutch teeth and protruding beyond its inclined surfaces by the clutch teeth of the adjacent clutch link; for any clutch link, the front clutch tooth has an inclination towards the front surfaces, and the rear clutch tooth has an inclination towards the rear surfaces; in any clutch link, the upper clutch tooth has an inclination in the first direction, and the lower clutch tooth has an inclination in the second direction; for any clutch link, the front clutch cavity is directed at an angle towards the front surfaces, and the rear clutch cavity is directed at an angle towards the rear surfaces; for any link, the upper clutch cavity is directed at an angle in the first direction, and the lower clutch cavity is directed at an angle in the second direction.

In addition, it must be indicated that the number of clutch links that form the connection head of each of the elements can be anything, but the decisive factor is that the minimum number of coupling links, which ensures a reliable connection of the element with the elements of the opposite tape, is two.

Since the number of clutch links of each of the elements according to this invention may be more than two, the odd or even number of the clutch links forming the connection head of each of the elements is also decisive, as discussed in more detail below.

Given these and other characteristics of the element, the description discloses in detail several examples of alternative designs of the zipper element according to this invention, provided as non-limiting examples, in which the connection head of the element is formed by a minimum even and a minimum odd number of links, that is, two and three links. respectively.

FIG. 17 - FIG. 20 shows successively axonometric, front view, top view and right side view of a zipper element according to the invention attached to the edge of a tape, in which the connection head is formed by two engagement links.

The element 20 according to the present invention consists of a base part 30 attached to the edge 13 of the first tape 11 and a connection head 32 protruding from the base part 30 and formed by two coupling links 33 for connection with opposite elements. Clutch links 33 are arranged one after the other in the direction of opposite elements and have the same configuration. Each of the clutch links 33 has two sidewalls 35 and two inclined surfaces 36. The clutch links 33, starting from the initial link of the clutch 33a and ending with the final link of the clutch 33b, are interconnected by a section of partial coincidence of their adjacent sidewalls 35. The initial and final links of the clutch 33a and 33b are connected to the sidewall 31 of the base part of the element 30 by the second sidewall 35 of the initial link 33a. The final clutch link 33b has opposite directions of inclination with the initial link 33a relative to the plane of the tape 11. The angles of inclination of the final link 33b and the initial link 33a relative to the plane of the tape 11 are equal in size. The plane of placement of the tape 11 passes through the middle of both links of the clutch 33a and 33b and through the middle of the area, which links the links 33a and 33b are connected to each other. The initial clutch link 33a has two directed in opposite sides of the clutch tooth 37 formed by its ends protruding beyond the inclined surfaces 36 of the adjacent final clutch link 33b. The final clutch link 33b also has two oppositely directed clutch teeth 37 formed by its ends protruding beyond the inclined surfaces 36 of the adjacent initial clutch link 33a. The initial clutch link 33a has two oppositely directed clutch cavities 38 formed by its inclined surfaces 36 together with its own clutch teeth 37 and protruding beyond its inclined surfaces 36 by the clutch teeth 37 of the adjacent clutch link 33b. The final clutch link 33b also has two oppositely directed clutch cavities 38 formed by its inclined surfaces 36 together with its own clutch teeth 37 and protruding beyond its inclined surfaces 36 by the clutch teeth 37 of the adjacent clutch link 33a.

Since the clutch teeth 37 of both clutch links 33a and 33b are oriented differently, then, according to the directions indicated above in the description, in the initial clutch link 33a, one clutch tooth 37 is defined as the front upper clutch tooth 37ac, and the second clutch tooth 37 is defined as the rear lower clutch tooth 37bd. Similarly, for the final clutch link 33b, in which one clutch tooth 37 is defined as the front lower clutch tooth 37ad, and the second clutch tooth 37 is defined as the rear upper clutch tooth 37bc. The same applies to the clutch depressions 38 of both clutch links 33a and 33b. According to the indicated directions at the start link 33a, one clutch cavity 38 is defined as the front lower clutch cavity 38ad, and the second clutch cavity 38 is defined as the rear upper clutch cavity 38bc. At the final clutch link 33b, one clutch cavity 38 is defined as the front upper clutch cavity 38ac and the second clutch cavity 38 is defined as the rear lower clutch cavity 38bd.

FIG. 21 - FIG. 24 shows successively axonometric, front view, top view and right side view of a zipper element according to the invention attached to the edge of a tape, the connection head of which is formed by two engagement links. The fastener element has an alternative design, when the direction of inclination of each clutch link is changed to the opposite relative to the plane of the fastener tapes.

Element 21 according to this invention has the same architecture as element 20. The difference between elements 21 and 20 is the different orientation of their clutch links 33a and 33b and the clutch teeth 37 and clutch cavities 38 formed by them. Since element 21 is an alternative to element 20, in fact its mirror image, the direction of inclination of the initial link 33a of element 21 and the direction of inclination of the initial link 33a of element 20 are opposite with respect to the plane of placement of the tape 11. Accordingly, the direction of inclination of the final link of the clutch 33b of element 21 and the direction of inclination of the final link of the clutch 33b of element 20 are also opposite with respect to the plane of placement of the tape 11. Formed by these links clutch teeth and clutch cavities of elements 21 and 20 are also opposite with respect to the plane of placement of the tape 11. So, according to the indicated directions, the initial link of the clutch 33a of element 21 has a front lower clutch tooth 37ad and a rear upper clutch tooth 37bc, a front upper clutch cavity 38ac and a rear a lower clutch cavity 38bd, and the final clutch link 33b of element 21 has a front upper clutch tooth 37ac and a rear lower clutch tooth 37bd, a front lower clutch cavity 38ad and a rear upper clutch cavity 38bc.

Having considered two samples of a fastener element with two clutch links, that is, with an even number of clutch links, it must be added that when using any even number of clutch links in an element, its final link always acquires the properties of every second link and has with its initial link opposite directions of inclination relative to the plane of the tapes. This property of an element with an even number of clutch links allows both rows of fastener elements to be formed by the same element. That is, both rows of elements 15 and 16 according to this invention can be formed by either: a plurality of element 20 (FIG. 1 with callouts A1, B1, C1; FIG. 4 with callouts A4, B4, C4; FIG. 9 with a remote image element D1;FIG. 12 with a remote image element D4); or in an alternative design by a plurality of element 21, where the direction of inclination of each link link is changed to the opposite relative to the plane of the tapes (FIG. 2 with remote image elements A2, B2, C2; FIG. 3 with external image elements AZ, VZ, SZ; FIG. Fig. 10 with a detail image D2;FIG. 11 with remote element of the image D3).

As noted above, for reliable connection of two rows of fastener elements, it is necessary that each of the elements from which the rows of elements are assembled has at least two clutch links. Therefore, the use of additional clutch links placed between the initial and final clutch links is also an alternative design of the fastener element. The following is a description of the fastener element according to the present invention, provided as a non-limiting example, the connection head of which consists of three engagement links, the smallest odd number of engagement links.

FIG. 25 - FIG. 28 are successively axonometric, front, top and right views of the first element of the zipper according to the invention attached to the edge of the tape, in which the head of the connection is formed by three links of the link.

The first element 22 according to the present invention consists of a base part 30 attached to the edge 13 of the first tape 11 and a connection head 32 protruding from the base part 30 and formed by three links 33 for connection with opposite elements. In this fastener element, between the initial link 33a and the final link 33b, one additional link 33c is placed. Clutch links 33a, 33c, 33b are arranged one after the other in the direction of opposite elements and have the same configuration. Each of the clutch links 33 (33a, 33c, 33b) is formed by two sidewalls 35 and two inclined surfaces 36. The clutch links 33, starting from the initial clutch link 33a and ending with the final clutch link 33b, are interconnected by a section of partial coincidence of their adjacent sidewalls 35. The initial, additional and final clutch links 33a, 33c and 33b are connected to the sidewall 31 of the base part of the element 30 by the second sidewall 35 of the initial clutch link 33a. The additional clutch link 33c has opposite directions of inclination relative to the plane of the tape 11 with the adjacent links of the clutch 33a and 33b. belt placement plane 11. The belt placement plane 11 passes through the middle of all three clutch links 33a, 33c and 33b and through the middle of the section by which the clutch links 33a, 33c and 33b are connected to each other. Starting link the clutch 33a has two oppositely directed teeth of the clutch 37 formed by its ends protruding beyond the inclined surfaces 36 of the adjacent additional link 33c. Additional clutch link 33c also has two oppositely directed clutch teeth 37 formed by its ends protruding beyond the inclined surfaces 36 of adjacent initial and final clutch links 33a and 33b. The final clutch link 33b accordingly also has two oppositely directed clutch teeth 37, formed by its ends protruding beyond the inclined surfaces 36 of the adjacent additional clutch link 33c. The initial clutch link 33a has two oppositely directed clutch cavities 38 formed by its inclined surfaces 36 together with its own clutch teeth 37 and protruding beyond its inclined surfaces 36 by the clutch teeth 37 of the adjacent additional clutch link 33c. The additional clutch link 33c also has two clutch cavities 38 directed in opposite directions, formed by its inclined surfaces 36 together with its own clutch teeth 37 and the clutch teeth 37 of adjacent initial and final clutch links 33a and 33b protruding beyond its inclined surfaces 36. The final clutch link 33b, respectively, also has two clutch cavities 38 directed in opposite directions, formed by its inclined surfaces 36 together with its own clutch teeth 37 and the clutch teeth 37 of the adjacent additional clutch link 33c protruding beyond its inclined surfaces 36.

Since the clutch teeth 37 of both clutch links 33a and 33b are oriented in the same way, but differently with the clutch teeth 37 of the additional clutch link 33c, then, according to the indicated directions at the initial and final clutch links 33a and 33b, one clutch tooth 37 is defined as the front upper clutch tooth 37ac , and the second clutch tooth 37 is defined as the rear lower clutch tooth 37bd. For the additional clutch link 33c, one clutch tooth 37 is defined as the front lower clutch tooth 37ad and the second clutch tooth 37 is defined as the rear upper clutch tooth 37bc. Similarly with the clutch depressions 38 of the clutch links 33a, 33c and 33b. According to the indicated directions at the initial and final clutch links 33a and 33b, one clutch cavity 38 is defined as the front lower clutch cavity 38ad, and the second clutch cavity 38 is defined as the rear upper clutch cavity 38bc. At of the additional clutch link 33c, one clutch cavity 38 is defined as the front upper clutch cavity 38ac, and the second clutch cavity 38 is defined as the rear lower clutch cavity 38bd.

FIG. 29 - FIG. 32 are successively axonometric, front, top and right views of the second zipper element according to the invention attached to the edge of the tape, the connection head of which is formed by three engagement links. The fastener element has an alternative design, when the direction of inclination of each clutch link is changed to the opposite relative to the plane of the fastener tapes.

The second element 23 according to this invention has the same architecture as the first element 22. The difference between the elements 23 and 22 is the different orientation of their engagement links 33a, 33c and 33b and the engagement teeth 37 and engagement cavities 38 formed by them. Since the second element 23 is an alternative to the first element 22, in fact its mirror image, then the direction of inclination of the initial link 33a of element 23 and the direction of inclination of the initial link 33a of element 22 are opposite relative to the plane of placement of the tape 11. Accordingly, the direction of inclination of the additional link 33c of element 23 and the direction of inclination additional link link 33c of element 22 are also opposite with respect to the plane of placement of the tape 11. And the direction of inclination of the final link link 33b of element 23 and the direction of inclination of the final link link 33b of element 22 are opposite relative to the plane of placement of the tape 11. The teeth and clutch cavities formed by these links elements 23 and 22 are also opposite with respect to the plane of placement of the tape 11. So, according to the indicated directions, the initial and final clutch links 33a and 33b of element 23 have a front lower clutch tooth 37ad and a rear upper clutch tooth 37bc, a front upper clutch cavity 38ac and a rear lower cavity 38bd, and the additional link 33c of element 23 has a front upper clutch tooth 37ac and a rear lower clutch tooth 37bd, a front lower clutch cavity 38ad and a rear upper clutch cavity 38bc.

Having considered two samples of a fastener element with three clutch links, that is, with an odd number of clutch links, it must be added that when any odd number of clutch links is used in the element, its the final clutch link always acquires the properties of such a link, which precedes every second clutch link, and has the same directions of inclination with its initial link with respect to the plane of the tapes. This property of an element with an odd number of clutch links does not allow the formation of both rows of fastener elements by the same element, as happens with an element with an even number of clutch links. An element with an odd number of linkage links of one tape requires an element of the opposite tape, which is essentially its mirror image. That is, according to this invention, if the first row of elements 15 of the first tape 11 is formed by the set of the first element 22, then the second row of elements 16 of the second tape 12 is respectively formed by the set of the second element 23, which is a mirror image of the first element 22 (FIG. 5 with remote elements of the image A5, B5, C5; FIG 8 with detail A8, B8, C8; FIG 13 with detail E1; FIG 16 with detail E4). Or in an alternative embodiment, where the direction of inclination of each link link is reversed with respect to the plane of placement of the tapes, then according to this invention, if the first row of elements 15 of the first tape 11 is formed by a plurality of the second element 23, then the second row of elements 16 of the second tape 12 is respectively formed by the plurality of the first element 22, which is a mirror image of the second element 23 (FIG. 6 with remote image elements A6, B6, C6; FIG. 7 with external image elements A7, B7, C7; FIG. 14 with external image element E2; FIG. 15 with external picture element E3).

The fastener chain consists of elements, the connection head of each of which is formed by two clutch links. Sections are shown, the secant planes of which pass through the coupling links. FIG. 34 is a front view of the fastener chain according to the present invention in a disengaged state.

Sections are shown, the secant planes of which pass through the coupling links. As seen in FIG. 33 and FIG. 34, the fastener chain 10 consists of a first tape 11 and a second tape 12. The first row of elements 15 is fixed along the edge 13 of the first tape 11. The second row of elements 16 is fixed along the edge 14 of the second tape 12. Both rows of elements 15 and 16 consist of elements 20, as shown in FIG. 33, or from elements 21, as shown in FIG. 34. Each of the elements 20 (FIG. 33) and each of the elements 21 (FIG. 34) has a connection head 32 formed by two clutch links 33, that is, the initial and final clutch links 33a and 33b. The first row of elements 15 is located opposite the second row of elements 16. This means that each of the elements 20 (FIG. 33) or elements 21 (FIG. 34) in the first row of elements 15 is directed by the second free sidewall 35 of its final clutch link 33b to the side the second row of elements 16. And vice versa, each of the elements 20 (FIG. 33) or elements 21 (FIG. 34) in the second row of elements 16 is directed by the second free sidewall 35 of its final clutch link 33b towards the first row of elements 15. That is , the elements of opposite rows are directed by their end links towards each other. This means that in the connected state of two rows of elements, the end link of the elements of each row is connected to the initial link of the elements of the opposite row, as shown in FIG. 37 and FIG. 38.

As seen in FIG. 37 and FIG. 38, in the connected state of two rows of elements 15 and 16, the final link of the clutch 33 of each of the elements 20 (FIG. 37) or elements 21 (FIG. 38) in the first row of elements 15 and the initial link of the clutch 33a of each of the elements 20 (FIG. 37) or elements 21 (FIG. 38) in the second row of elements 16 are connected to one another by parallel contact with their inclined surfaces 36 (section K1-K1 (FIG. 37), section K2-K2 (FIG. 38)). Accordingly, the initial clutch link 33a of each of the elements 20 (FIG. 37) or elements 21 (FIG. 38) in the first row of elements 15 and the final clutch link 33b of each of the elements 20 (FIG. 37) or elements 21 (FIG. 38 ) as part of the second row of elements 16 are connected to each other by parallel contact with their inclined surfaces 36 (section J1-J1 (FIG. 37), section J2-J2 (FIG. 38)).

As can be seen from the image of the sections K1-K1, J1-J1 (FIG. 37) and K2-K2, J2-J2 (FIG. 38), the connection of the final links of the coupling of elements of one row with the initial links of the coupling of elements of the opposite row by parallel contact with their inclined surfaces possibly due to the same direction of inclination of these clutch links relative to the plane of the tapes. Paired sections G1-G1 and F2-F2, G2-G2 n F1-F1 (FIG. 33), as well as sections G3-G3 and F4-F4, G4-G4 and F3-F3 (FIG. 34) show the appearance of the same the direction of inclination of the final and initial links of the coupling of opposite elements relative to the plane of the tapes, when both rows of elements are in a disconnected state.

Each of the elements 22 and each of the elements 23 has a connection head 32 formed by three links of the clutch 33, that is, the initial link of the clutch 33a, the final link link 33b and located between them an additional link link 33c. The first row of elements 15 is located opposite the second row of elements 16. This means that each of the elements 22 (FIG. 35) or elements 23 (FIG. 36) in the first row of elements 15 is directed by the second free sidewall 35 of its final clutch link 33b to the side the second row of elements 16. And vice versa, each of the elements 23 (FIG. 35) or elements 22 (FIG. 36) in the second row of elements 16 is directed by the second free sidewall 35 of its final clutch link 33b towards the first row of elements 15. That is , the elements of the opposite rows are directed by their end links towards each other. This means that in the connected state of the two rows of elements, the end link of the elements of each row is connected to the initial link of the elements of the opposite row, and the additional link of the elements of each row is connected to the additional link of the elements of the opposite row, as shown in FIG. 39 and FIG. 40.

FIG. 39 is a front view of the fastener chain according to the present invention in a connected state. The fastener chain consists of elements, the connection head of each of which is formed by three clutch links. Sections are shown, the secant planes of which pass through the coupling links. FIG. 40 is a front view of the fastener chain according to the present invention in a connected state. The fastener chain consists of elements, the connection head of each of which is formed by three clutch links. Each of the elements of the fastener has an alternative design, when the direction of inclination of each clutch link is changed to the opposite relative to the plane of placement of the fastener bands. Sections are shown, the secant planes of which pass through the coupling links.

As seen in FIG. 39 and FIG. 40, in the connected state of two rows of elements 15 and 16, the final link of the clutch 33b of each of the elements 22 (FIG. 39) or elements 23 (FIG. 40) in the first row of elements 15 and the initial link of the clutch 33a of each of the elements 23 (FIG. 39) or elements 22 (FIG. 40) in the second row of elements 16 are connected to one another by parallel contact with their inclined surfaces 36 (section L3-L3 (FIG. 39), section L4-L4 (FIG. 40)). Accordingly, the initial clutch link 33a of each of the elements 22 (FIG. 39) or elements 23 (FIG. 40) in the first row of elements 15 and the final clutch link 33b of each of the elements 23 (FIG. 39) or elements 22 (FIG. 40) in the second row of elements 16 are connected to one another by parallel contact with their inclined surfaces 36 (section J3-J3 (FIG. 39), section J4-J4 (FIG. 40)). Located between the initial and final clutch links 33a and 33b, an additional clutch link 33c of each of the elements 22 (FIG. 39) or elements 23 (FIG. 40) in the first row of elements 15 and located between the initial and final clutch links 33a and 33b additional link clutch 33c of each of the elements 23 (FIG. 39) or elements 22 (FIG. 40) in the second row of elements 16 are connected to one another by parallel contact with their inclined surfaces 36 (section KZ-KZ (FIG. 39), section K4-K4 (FIG. 40)).

As can be seen from the image of the sections L3-L3, J3-J3, KZ-KZ (FIG. 39) and L4-L4, J4-J4, K4-K4 (FIG. 40), the connection of the final links of the clutch elements of the same row with the initial links of the clutch elements of the opposite row by parallel contact with their inclined surfaces is possible due to the same direction of inclination of these clutch links relative to the plane of the tapes. Additional clutch links of the elements of both rows are also interconnected by parallel contact of their inclined surfaces due to the same direction of inclination of these clutch links relative to the plane of the tapes. Paired sections H5-H5 and F6-F6, H6-H6 and F5-F5, G5-G5 and G6-G6 (FIG. 35), as well as sections H7-H7 and F8-F8, H8-H8 and F7-F7 , G7-G7 and G8-G8 (FIG. 36) show a view of the same direction of inclination of the end, initial and additional links of the coupling of opposite elements relative to the plane of the tapes, when both rows of elements are in a disconnected state.

As noted above, according to this invention, any clutch link in the composition of the connection head of each of the elements has opposite directions of inclination with the neighboring clutch link relative to the plane of the tapes, that is, the adjacent clutch links are located crosswise to one another. Therefore, any clutch link of each of the elements has, on the side of the adjacent link, a pair of clutch teeth protruding beyond its inclined surfaces, formed by two ends of the adjacent link link directed in opposite directions. In addition, any engagement link of each of the elements also has two engagement cavities formed by its inclined surfaces together with its own engagement teeth and the engagement teeth of an adjacent engagement link. Therefore, in the combined In the state of two rows of elements, any link of the clutch of the elements of one row is with its clutch teeth in the clutch depressions formed by the links of the clutch belonging to the elements of the opposite row, and this causes the creation of a reliable connection of the elements of the opposite rows.

According to this invention, in the connected state of the two rows of elements 15 and 16, as shown in FIG. 37, the front lower clutch tooth 37ad of the final clutch link 33b of elements 20 in the first row of elements 15 is located in the front upper clutch cavity 38ac of the initial clutch link 33a of elements 20 in the second row of elements 16, and the rear upper clutch tooth 37bc of the final link of the clutch 33b elements 20 in the first row of elements 15 is located in the rear lower cavity of the clutch 38bd (not shown) of the initial link 33a of elements 20 in the second row of elements 16. The front upper clutch tooth 37ac of the initial link 33a of elements 20 in the first row of elements 15 is located in the front lower clutch cavity 38ad of the final clutch link 33b of elements 20 in the second row of elements 16, and the rear lower clutch tooth 37bd of the initial clutch link 33a of elements 20 in the first row of elements 15 is located in the rear upper clutch cavity 38bc (not shown) of the final link link 33 elements 20 as part of the second row of elements 16.
