DESCRIPTION

Cursor for hidden zip closure.

Technical field

The invention relates to a cursor for concealed zip closure according to claim 1 which does not leave the main body of a cursor that is an opening / closing element exposed to the outside, when closing a zip closure. In addition, the invention relates to a cursor for a hidden zipper closure that allows smooth operation of a cursor, even if a significant transverse traction force is applied to the cursor when closing the hidden zipper closure.

Prior art

These types of hidden zip fasteners have been used for women's clothing, but recently, zip fasteners have been used in other fields than for clothing. For example, zip fasteners are used for seat leaves in vehicles or trains. Such zip fasteners are known from US 2006/0000066 A1 and DE 202 606 A1.

The seat sheets cover a monolophically shaped cushion body with a frame in advance. The dimensions of the seat cover are configured to be smaller than the outer size of the cushion body and the seat sheets are configured to cover the cushion body with compressed state and prevent maximum situations such as loosening or deformation that It is generated in the external form.

In addition, the cushion body is elastically deformed when a passenger sits on it to distribute and receive the passenger's load in an equivalent manner and the seat cover is also configured to elastically deform, corresponding to the elastic deformation of the cushion body. In addition, the cushion body returns to the original form when the passenger gets up from the seat and the cover is also configured to return correspondingly safely to the original form. As the seat cover is configured to follow the deformation of the cushion body, the shape of the seat leaves is prevented from deforming.

The seat cover is generally configured by natural leather, synthetic leather, or a stacked and integrated seat. The stacked and integrated seat is formed in a stacked and integrated configuration by laminating a surface layer, a thin elastic intermediate layer and a rear bubble layer. A genre such as a fabric having several structures is used for the surface layer and one such as a polyurethane foam sheet is used for the thin elastic intermediate layer. In addition, a genre such as thin fabric made by knitting or crochet work very thin lines of threads are used for the back bubble layer.

In general, a plurality of pieces of cut sheets to fit the shape are combined and sewn in a three-dimensional shape to make the seat cover for the seat sheets from the sheets. However, when the entire seat cover is sewn, in many cases the seat cover cannot cover the cushion body of a seat with a complicated external shape. Therefore, in the related art, a non-stitched section is formed in advance in a seat cover, the seat cover covers the cushion body, and then the non-stitched section is sewn by hand.

When the final finishing work is done by hand sewing, a difference is easily generated in the quality of the complete product or the sewing time to finish a complete product according to the difference in skills of the workers. Therefore, recently, in order to eliminate the finishing work by hand sewing, a zipper closure is increasingly used along the seams, for example, in a section of the sewn section of a sheath of seat.

In addition, as the zipper closure that is used for a seat leaf, a hidden zipper closure is increasingly used of which the cursor body is not exposed to the outside to improve the design of the external appearance. Since the zipper closure is used, it is possible to perform all sewing with a sewing machine to significantly reduce conventional problems caused by the difference in skills, so that productivity is greatly improved.

When the hidden zipper closure is used for a vehicle seat leaf and the like, as described above, since the seat cover is configured to be smaller than the outer size of the cushion body, a force is applied of transverse traction important to the closing band around the cursor. As a result, when a closure band is used in which the side of the closure tape is folded and fixed in a U-shape and a closure element is fixed along the edge of the folded end of the sides and when applied an important transverse traction force on the closing band, the closing element is raised by

The great transversal traction force. That is, the closure element is placed vertically to the tape surface of the closure tape, with the coupling head facing up.

In addition, while each closure element that is inserted into a shoulder opening of the cursor while receiving a significant transverse traction force around the shoulder opening is substantially vertical to the tape surface of the closure tape, the element of Closure is introduced at the cursor from the shoulder opening.

In each closing element, when a rear end section of the element positioned opposite a coupling head is located at the top of a lower flap of the cursor, the rear end section of the element can be tilted at an angle in one direction to be in a substantially horizontal state. However, the angle is small, so that the closure element is inserted into the cursor from the shoulder opening while standing. As a result, the closure element is sandwiched by tape guides guiding the closure tape and the cursor cannot slide.

When the cursor is forced to slide in this state, the closure element where the transversal traction force is exerted is damaged. Also, in the worst case, the folded edge of the closure tape can be cut. In addition, when the closure element is not completely in the horizontal state and is inserted into the cursor, the opposite closure elements are not precisely coupled when the zip closure is closed, and a so-called puncture state is generated.

As a cursor that can be used for the hidden zipper closure where the large transversal traction force is applied, the applicant has already proposed cursors for a hidden zipper closure (see patent documents 1 and 2). The hidden zipper closure includes a pair of closure bands in which the side of the closure tape is folded and fixed in a U-shape and a closure element is coupled along the folded edge of the side.

The cursor for a hidden zipper closure described in patent document 1 is exemplified as a first related technique of the invention and Figure 9 shows a perspective view of the cursor. As shown in Figure 9, a pair of first left and right flanges 43 and 44 having an inverse L-shaped cross section along the edges is disposed on the left and right edges of a lower fin 42 of a cursor 41. A guide column 45 having a substantially elliptical horizontal cross section is arranged in the central section of the leading edge of the lower fin 42.

A rectangular zone 46a and a cradle-shaped area 46b which are monolophically formed in the upper part of the guide column 45 are provided in a cradle-shaped space defined between the upper plates 43a and 44a of the pair of first flanges 43 and 44, and a second flange 46 protruding outwardly along the outer periphery of the guide column 45 is arranged. In addition, the height of the bottom surface from the bottom fin 42 at the end of the second flange 46 whose side is the shoulder opening becomes greater than the height of the bottom surface from the bottom fin 42 in another area and a tapered surface 46c which has a tapering angle that gradually increases towards the rear opening is formed on the outer surface of the second flange 46.

In the invention of the patent document 1, such as the height to the lower fin 42, the height in the upper edge of the tapered surface 46c in the shoulder opening of the second flange 46 is made greater than the height in the upper edge of the second flange 46c in the rear opening. By this configuration, even if the closure element is inserted into the cursor 41 from the shoulder opening in the state of slight inclination to the horizontal direction from the upright state, the closure element is guided to the tapered surface 46c of the second pestana 46 and is introduced in a guiding step of elements 49, without interfering with the second flange 46.

While the closing element is introduced in the element guiding passage 49, the connecting section of the element gradually tilts to pass through the lower surface of the second flange 46, due to the combined influence of guided by the tapered surface 46c of the second flange 46 and the force that inclines the closing element due to the tensile force of the previous element and the closing tape. In addition, the closure element that has been introduced in the element guiding passage 49 is fixed in the posture inclined by the upper plates 43a and 44a of the pair of first flanges 43 and 44 and the second flange 46 and moves smoothly in the element guidance step 49 of cursor 41.

In addition, the closure element is not sandwiched between the upper plates 43a and 44a of the lower fin 42 and the second flange 46, and it is possible to prevent the closure element from being damaged and the closure tape being cut. In addition, the cursor 41 can slide smoothly and the cursor 1 for a hidden zip closure can be closed without problems.

The cursor for a hidden zipper closure described in patent document 2 is exemplified as a second related technique of the invention and Figure 10 shows a perspective view of the cursor. How I know

shown in FIG. 10, a pair of flanges 53 and 54 having an inverse L-shaped cross section is arranged along the left and right sides perpendicular to the direction of sliding of a cursor 51, from a lower fin 52 .

A guiding column 55 is disposed between a pair of upper plates 53a and 54a, in the central section of the leading edge of the lower fin 52. An element guiding section 57 protruding outward towards the inner end surface 56 of the plates upper 53a and 54a is arranged on the outer periphery of the guide column 55 and the front end of the upper plates 53a and 54a in the direction of engagement of the closure element 59 extends further forward than the front end of the section of guiding elements 57.

In the invention of patent document 2, the front end in the direction of engagement of the closure element 59 in the upper plates 53a and 54a extends further forward than the front end of the element guide section 57. By this configuration , even if the closure element 59 is perpendicular to the closure tape 60, with the coupling head 59a facing up, in the position in which the closure element 59 is spaced forward in the direction of coupling beyond the cursor 51, the closure element 59 is guided at the cursor 51 in contact with the upper plates 53a and 54a that extend forward beyond the front end of the element guide section 57.

Also, since the closure element 59, guided at the cursor 51 in contact with the upper plates 53a and 54a, is influenced by the anterior closure element 59 inclined at an angle in the horizontal posture, a tilt force is applied For the horizontal state. In addition, the pulling force that pulls the closure tape 60 at the cursor 51 is applied to the closure element 59, based on the sliding operation of the cursor 51.

Accordingly, the pair of left and right closure elements 59 inclines in the horizontal state from the vertically upright posture, until it enters the guide element passage of the cursor 51. Also, since the closure tape 60 moves Near the guide column 55 in sliding contact with the upper plates 53a and 54a, the coupling head 59a of the closure element 59 can be brought into contact with the element guide section 57.

In addition, each closure element 59 appropriately inclined to the horizontal state is introduced in the element guide passage 58 of the cursor 51 while bringing the coupling head 59a in contact with the element guidance section 57. The coupling head 59a of the element closure 59 can move smoothly towards the rear opening in the element guide passage 58 while slowly leaning towards the posture that passes through the element guide section 57 downwards.

Therefore, it is possible to couple the pair of left and right closure elements 59 in the correct posture (coupling posture) fully inclined in the horizontal state. In addition, unlike the related technique, the closure element 59 is not pinched by the tape guide passage formed between the flanges 53 and 54 and the element guide section 57, and the closure element 59 can be prevented is damaged or the closure tape 60 is cut. As described above, in the invention of the patent document 2, the cursor 51 can slide smoothly and the hidden zip fastener can be closed without any problem.

Summary of the invention

Problems to be solved by the invention

As the basic configurations of the inventions in patent documents 1 and 2, for the closure element erected in the posture perpendicular to the closure tape, the closure element can move at an angle to a horizontal posture guiding the coupling head of the closing element.

Therefore, in the inventions of patent documents 1 and 2, when the closure element that is in the

vertical upright posture moves at an angle in the horizontal posture, as the guiding section that

the moment of rotation in sliding contact with the coupling head of the closure element, the second flange 46 projecting outwardly along the outer periphery of the guide column 45 and the guide section of elements 57 are arranged in the invention of patent document 1 and the invention of patent document 2, respectively.

Through the configurations of the inventions in patent documents 1 and 2, the closure element that is in the vertical upright posture can move at an angle in the horizontal posture that is the coupling posture.

However, the closing element inclined by the transverse traction force applied to the closing belt is inclined at various angles by the direction in which the transverse traction force is applied and the magnitude of the transverse traction force. Therefore, the angle at which the closure element is in contact with the guide section that can be applied at the moment of rotation is not stable.

Also, when a greater transverse tensile force is applied to the closure tape, the closure element slides in the longitudinal direction of the closure tape without actively coming into contact with the guiding section and the closure element may not return smoothly. to the horizontal position so that there is still a need for improvement.

In particular, when the closure element is sewn and fixed by a thread along the extreme edges of the closure tape, the closure element is not monolphically fixed to the closure tape. Therefore, the closure tape under a large transverse traction force can move transversely while movement relative to the closure element is generated.

When the amount of movement of the closure element is less than the amount of movement of the closure tape in the transverse direction, for example, in the invention of patent document 1, the head section of the closure element cannot enter contact with or press the tapered surface 46c of the second flange 46 with great force. Furthermore, in the invention of the patent document 2, the coupling head 59a of the closure element 59 cannot come into contact with or press the guide section of elements 57 with great force.

In this state, for the closing element in an inclined posture, it is impossible to apply a rotation moment to change the upright posture to the horizontal state to the closing element, using the tapered surface 46c of the second flange 46 or the guiding section of elements 57.

The inventor (s) of the invention has achieved the invention, based on the fact that it is possible to move the closure element at an angle to a horizontal posture that is a coupling posture, bringing the rear end section of the element of the closure element into contact. sliding with a second element guidance section at the time or before bringing the rear end section of the element into contact with a first element guidance section corresponding to the tapered surface 46c of the patent document 1 or the element guidance section 57 of patent document 2, as a result of several examinations.

In addition, by configuring the cursor for the hidden zipper closure as the invention, it is possible to effectively apply a force applied to the closure element from the second element guidance section, torsional force that moves the closure element at an angle to a posture. horizontal from a previous closing element that has moved at an angle to a horizontal state, traction force that drags the closing tape on the cursor and similar to the closing element that is introduced on the cursor.

Applying these forces to the closure element, the closure element in the upright posture substantially perpendicular to the closure tape moves at an angle to a horizontal posture that is the coupling posture. In addition, the closure band can move smoothly towards the rear opening through the guiding passage of Y-shaped elements formed in the cursor while gradually tilting. Therefore, the closing element moves smoothly through the guiding step of Y-shaped elements formed in the cursor.

In addition, the closing element does not get stuck in the guiding step of Y-shaped elements, so that the cursor can slide smoothly.

As described above, an object of the invention is to provide a cursor for a hidden zipper closure that allows a cursor to slide smoothly even if an important transverse traction force is applied when a zipper closure is closed, improving inventions of Patent documents 1 and 2.

Means to solve the problems

In order to achieve the object, a cursor for a hidden zipper closure provided with a folded and fixed U-shaped closure tape and attaching / separating closure elements from a pair of closure bands, the closure elements are coupled along the end edge of the folded closure tape, it is characterized in that the cursor comprises a lower flap; a pair of side walls provided to be erected along both edges in the left-right direction perpendicular to the sliding direction of the cursor 1 in the lower fin; a pair of upper plates extending to be close to each other from the ends

In addition, in the invention, the second element guide section is disposed in the same position as the front end of the side of the shoulder opening or beyond the front end of the side of the shoulder opening of the guide column in the cursor slide direction.

Also, in the invention, the first element guiding section has a lateral guiding surface formed towards the rear opening from one side of the guiding column and having a parallel surface in the direction of sliding of the cursor and a guiding surface. front inclined towards the side of the shoulder opening and upward as a surface that continues with the lateral guiding surface, and the first element guidance section is opposite the second element guidance section.

In addition, in the invention, the second element guiding section is a protruding section formed from the inner wall of the lower fin to the inner walls of the side walls.

Also, in the invention, the projecting section has an inclined surface that slopes towards the side walls from the lower fin and the inclined surface is opposite the first element guiding section.

Also, in the invention, in the tape guide step, the Y-shaped tape guide step whose side is the shoulder opening divided into two lines towards the cursor shoulder opening is open and widened straight towards the opening of the cursor shoulder, and the second element guide section extends in the axial direction inclined inward beyond the axial line of the tape guide passage whose side is the shoulder opening.

In addition, in the invention, the starting position of the second element guiding section that begins to guide the rear end section of the element in sliding contact may be arranged in front of the starting position of the first guiding section of elements that begins to guide the coupling head of the closure element in sliding contact.

Also, in the invention, the front end of the shoulder opening of the second element guide section is disposed in front of the inclined surface positioned closer to the lower fin than the inner walls of the upper plates, in the first section. of guiding elements.

Also, in the invention, the closure element is fixed by sewing along the end edge of the closure tape.

Also, in the invention, seen from above, a front end edge in the direction of engagement of the closure element in the pair of upper plates extends near a front end edge of the lower fin, and a curved section is formed by beveling at the opposite internal corners of the front end edge of the upper plates.

In addition, in the invention, the front end edge in the pair of side walls is disposed on the side of the rear opening beyond the front end in the second element guiding section.

Effect of the invention

The invention relates to a cursor for a hidden zipper closure in which a side edge opposite a closure tape is folded and fixed in a U-shape and a pair of closure bands is provided where a closure element is coupled to along the folded edge of the side edge.

In this report, it is described when the front end sections of a pair of upper plates where the folded section of the closure tape introduced in a cursor is in sliding contact are pivots where the closure tape is curved by transverse force. In this state, in the pair of closing bands, the distance from the pivot to a rear end section of the element is greater than the distance from the pivot to a head of

coupling Therefore, as a rotation moment that inclines the closing element, a greater rotation moment can be applied to the closing element by guiding the rear end section of the element in sliding contact instead of guiding the coupling head in sliding contact.

As described above, even if the closure element just before entering the cursor is inserted into an erect posture substantially perpendicular to the closure tape, guiding the rear end section of the element positioned opposite the coupling head as the section of the closing element that is guided first, the rotation time to efficiently perform a horizontal posture can be effectively applied to the closing element.

Also, when the closure element is sewn and coupled by a thread along the end edge of the closure tape, the closure element is not monolphically fixed to the closure tape, so that even if the closure tape is moved by a transversal traction force, the closure element is left without moving monolophically with the movement of the closure tape. However, the closure element moves monolphically in the direction of movement along the tape guide passage of the closure tape.

Therefore, in the movement of the closure tape along the tape guide passage, the rear end section of the closure element moves in sliding contact with the second element guide. In addition, the coupling head of the closure element is moved to the first element guide by the second element guide, so that the coupling head can come into contact with the first element guide.

As described above, the rear end section of the element is guided in contact with the second element guiding section and may come into sliding contact with the first element guide. In addition, the closure element in an upright state can be changed to a horizontal state by the second element guidance section.

In addition, the coupling head of the closure element supported by the second element guidance section can be safely tilted to a horizontal posture by being carried in sliding contact with the first element guidance section.

In the invention, to guide the rear end section of the element at the cursor, the second element guide section guiding the rear end section of the element may extend to the rear opening from the front end edge of the lower fin, on both sides. left and right of the lower fin. In addition, as a configuration of the second element guidance section, the second element guidance section is arranged opposite one side of the guide column and protrudes towards the upper plate from the lower fin.

With this configuration, even if the closing element just before entering the cursor is in an erect posture substantially perpendicular to the closing tape, guiding the rear end section of the element, a rotation moment can be applied to perform a horizontal posture efficiently. effectively to the closing element.

In addition, the coupling head of the closure element can be supported by the second element guide section such that the angle and position of the closure element are within predetermined ranges when they are in sliding contact with the first guidance section. Of elements. Accordingly, the coupling head of the closure element may be in sliding contact with the first element guiding section in a stable state.

In the invention, such as the arrangement relationship of the second element guiding section and the guiding column, the second element guiding section may be arranged in the same position as the front end of the shoulder opening side of the guide column or beyond the front end of the side of the shoulder opening in the direction of sliding of the cursor. By this configuration, the closing element can be inclined to a horizontal posture before or when the closing element is introduced in the element guiding step, so that the closing element can pass smoothly through the cursor.

In the invention, such as the configuration of the first element guiding section, the first element guiding section may be formed towards the rear opening from one side of the guiding column. In addition, the first element guiding section may have a lateral guiding surface provided with a parallel surface in the direction of sliding of the cursor and a leading front guiding surface inclined towards the side of the shoulder opening and upwards as a surface that Continue with the lateral guidance surface. In addition, the first element guidance section and the second element guidance section may be opposite to each other.

Through this configuration, the closing element can be inclined effectively to a horizontal posture by means of the cooperation of the first element guidance section and the second guidance section of

elements. Furthermore, after entering the rear end section of the element in sliding contact with the second element guiding section, the coupling head of the closing element can be carried in sliding contact with the first element guiding section.

Furthermore, after the closure element in the upright posture substantially perpendicular to the closure tape has tilted slightly in the direction in which a horizontal state is established by the second element guide section or after the element of The closure element has been brought into sliding contact with the second element guidance section, the closure element can be safely tilted to the horizontal state by cooperating with the first element guidance section and the second element guidance section.

Like the configuration of the second element guidance section, the second element guidance section may be a protruding section formed from the inner wall of the lower fin to the inner walls of the side walls. Through this configuration, a guiding surface and / or a stepped guiding section can be configured in the outgoing section. Also, as a configuration of the guiding surface, the guiding surface can be an inclined surface that slopes towards the side walls from the lower fin and a surface arranged opposite to the first element guiding section.

Through this configuration, the closure element can be effectively inclined to a horizontal posture by the second element guide section. In addition, the moment of rotation to make the closure element in an erect position substantially perpendicular to the closure tape passes to a horizontal state can be effectively applied to the rear end section of the element from the guiding surface and / or the stepped section. of guiding the second section of guiding elements. In addition, by configuring the guiding surface as an inclined surface, the closure element can be guided effectively to lean in a horizontal state along the inclined surface.

In the invention, in the Y-shaped tape guiding passage, such as the configuration in the shoulder opening divided into two lines towards the cursor shoulder opening, the tape guiding passage can be opened and widened straight towards the opening of the cursor shoulder, and the second element guide section extends in the axial direction inclined inward beyond the axial line of the tape guide passage whose side is the shoulder opening.

By this configuration, the radius of curvature can be broadly configured when the folded section of the closure tape that is in contact with the leading end edges of the pair of upper plates is curved in the longitudinal direction of the closure tape. Therefore, it is possible to gently insert the closure band under a transverse traction force in the tape guide passage. In addition, it is possible to suppress the angle of verticality of the closure element that is erected substantially perpendicular to the closure tape.

In addition, the shape of the Y-shaped tape guide passage may be configured to open and widen straight and the axial line of the second element guide may be inclined inwardly with respect to the axial line of the open and widened straight form. . Through this configuration, the closing element can be moved more securely near the first element guide when it is moved towards the rear opening of the cursor. Therefore, the closure element can be brought into gentle contact with the first element guiding surface and can be tilted in a horizontal state.

In particular, in the type of element used that is sewn to the closure tape by a thread, even if the closure tape is moved by the traction force and the closure element is left separated in the lateral direction of the tape In closing, the gap between the second element guide and the tape guide passage is configured to be small towards the rear opening of the cursor, such that the separate closing element can be forcibly returned to the initial position.

In the invention, the starting position of the second element guide section that begins to guide the rear end section of the element in sliding contact may be arranged in front of the first element guide section that begins to guide the coupling head. of the closing element in sliding contact.

By this configuration, such a thing as the position or angle of the closing element can be supported by the second element guide within predetermined ranges, before the closing element comes into contact with the first element guide. In addition, because the position or angle can be set within predetermined ranges, the angle of inclination of the closure element can be effectively changed to the direction of horizontal posture by the second element guide.

In the invention, the front end of the shoulder opening of the second element guide section may be disposed in front of the inclined surface positioned closer to the lower fin than the inner walls of the upper plate, in the first section of Guided elements.

By this configuration, even if the closing element just before entering the cursor is in an upright posture substantially perpendicular to the closing tape, the closing element can first be brought into sliding contact with the second element guiding section. In addition, the rotational movement to put the closure element in a horizontal posture can be applied before the second element guidance section.

In the invention, seen from above, a front end edge in the direction of engagement of the closure element in the pair of upper plates may extend near a front end edge of the lower fin, and a curved section may be formed by chamfering in the opposite inner corner of the front end edge of the pair of upper plates.

By this configuration, even if the closure element just before entering the cursor is in an erect posture substantially perpendicular to the closure tape, the closure element can be made to tilt to a horizontal posture by cooperation of the front end edge upper and the second section of guiding elements.

In the invention, the opposite internal corners of the front end edges of the upper plates are formed as curved sections formed by chamfering. Also, by bringing the closure tape in sliding contact with the opposite inner corners, when a large tensile force is applied in the transverse direction to the folded section of the closure tape, the curved section formed in the opposite inner corner can receive the great traction force applied to the folded section of the closure tape. Therefore, it is possible to reduce the concentration of stresses in the curved section, in the closure tape.

As described above, it is possible to prevent the closure tape from being cut also in the process of tilting the closure element to a horizontal posture that is a coupling posture.

In the invention, the position of the front end edge in the pair of side walls may be arranged in the rear opening beyond the front end in the second element guide.

By this configuration, when the folded section of the closure tape that is in contact with the leading end edges of the pair of upper plates is curved in the longitudinal direction of the closure tape, the gap between the end of the front side of the second Guiding section of elements and the ends of the front sides of the pair of side walls can function as a space to avoid interference with the closure element.

Also, when the folded section of the closure tape that is in contact with the leading end edges of the pair of upper plates is curved to take the form of the curved section at the leading end edges of the pair of upper plates that are chamfered, the Closure element can be curved smoothly without coming into contact with the front ends of the pair of side walls.

In the invention, before the coupling head of the closure element is forcibly rotated in the direction of the horizontal posture by the first element guiding section or before the closure tape is curved in the longitudinal direction by the front end edges of the pair of upper plates, the moment of rotation that rotates the closure element in a horizontal position direction can be applied to the rear end section of the element of the closure element by the second element guidance section.

In addition, the closure tape can be gently inserted into the tape guide passage and the angle of inclination of the closure element when the coupling head of the closure element comes into sliding contact with the first element guidance section can be made in the direction of horizontal posture.

gradually. In addition, the width form in the left-right direction of the lower flap 2 on the front side from the enlarged opening 23b is configured as the parallel section 23a.

In addition, in figure 2, seen from above, in cursor 1, a plan view of the cursor is shown in the left half of figure 2 and a cross-sectional view with the first guiding section of elements 7 and the plate Upper 3b removed is shown in the right half in Figure 2. In addition, the first element guiding section 7 and the upper plate 3b removed are shown in imaginary shapes by dotted lines in the right half of Figure 2.

Viewed from above, as shown in Figure 2, the front end edges 21 of the upper plates 3b and 4b extend around the front end edge 2a of the lower fin 2. According to this configuration, the bottom side at the front end edge 21 of the upper plates 3b and 4b is configured as a space that is not supported by the side walls 3a and 4a.

That is, the front end edges 21 of the upper plates 3b and 4b preferably extend further forward than the front ends 20a of the side walls 3a and 4a. In addition, it is preferable that the gap between the front end edges 21 of the upper plates 3b and 4b and the front end 20 of the side walls 3a and 4a is configured such that the closure element 13 mounted on the hidden zipper closure may pass without interfering with the front ends 20 of the side walls 3a and 4a.

As shown in Figure 1, the opposite internal corners opposite each other at the front end edges 21 of the upper plates 3b and 4b are formed as a curved section 21a where the chamfer is made. In addition, the end surface where the upper plates 3b and 4b are opposite each other is configured as an inner end surface 21b.

The guide column 5 is intended to be erected in the central section in the left-right direction of the lower flap 2, around the shoulder opening 16 of the cursor 1. In addition, the pull-tab mounting column in the form of door 6 extending in the front-rear direction is arranged on the upper surface of the guide column 5. In addition, the first guide section of plate-shaped elements 7 protruding outward towards the inner end surfaces 21b of the pair of upper plates 3b and 4b from the outer periphery of the guide column 5 is arranged on the outer periphery of the guide column 5.

A drag tongue (not shown) can be supported by the drag tongue mounting column 6 by inserting the ring-shaped section of the drag tongue into the drag tongue mounting column 6 in an example of figure and then crimping the pull tab mounting column 6.

As a configuration of the guide column 5, as in document PCT / JP2009 / 64927 by the applicant (s), a two-division configuration consisting of a body section 19 where the lower fin 2 is intended to rest and an element of upper cover plate 18 applied on and adjusted to the body section 19 can be implemented. In addition, as shown in patent documents 1 and 2, the guide column 5 may be monolphically formed with the lower fin 2.

In the configuration of the guide column 5 shown in Figure 4, an example of a two-partition configuration is shown, consisting of the body section 19 and the upper cover plate element 18. A convex section, in which it is mounted a concave section formed in the upper cover plate element 18, is formed on the outer surface of the body section 19. The upper cover plate element 18 can be fixed to the body section 19 by adjusting the concave section of the body element. upper cover plate 18 in the concave section formed on the outer surface of the body section 19 and then crushing a leg section 18a formed at the front end of the upper cover plate element 18, as shown in Figure 3.

Like the concave section of the upper cladding plate element 18, the concave section of the upper cladding plate element 18 may be configured to be closed at the rear end. By this configuration, both the front and rear end surfaces of the body section 19 can be interposed between the closed rear end of the concave section of the top cover plate element 18 and the leg section 18a.

As shown in Figs. 1 and 4, a front guide surface 7a is formed by tilting the front end of the upper cover plate element 18 forward, on the outer surface of the upper cover plate element 18. Also, in the inner wall of the upper cover plate element 18, a lateral guiding surface 7b is formed which continues from the left and right of the front guiding surface 7a towards the rear opening 17 from the side of the guiding column 5 and towards the lower fin 2.

In other words, the lateral guiding surface 7b is a surface that is parallel to the inner wall surface 2b of the lower flap 2, when the inner wall of the first guiding section of plate-shaped elements 7 protrudes from the column of guidance 5. Meanwhile, the front guide surface 7a is an inclined surface that is inclined upwardly from the front end of the side guide surface 7b and formed on the front end surface of the first element guide section 7 with plate shape.

The first element guide section 7 is configured by the front guide surface 7a and the pair of left and right side guide surfaces 7b. As shown in Figure 3, the first element guidance section 7 is configured to be opposite the second element guidance section 8 which will be described below.

In addition, in Figure 1, an example in which the forward bending state of the front guide surface 7a is shown is the flat inclined flat surface, but the forward bending state of the front guide surface 7a It can be formed on a curved surface of a concave surface or a convex surface.

The pull tab mounting column 6 that supports the pull tab (not shown) is provided to be erected on the upper surface of the upper cover plate member 18. Even if the guide column 5 is monolphically formed with the lower flap 2, the front guide surface 7a and the pair of left and right side guide surfaces 7b are necessarily configured in the guide column 5, as the first element guide section 7.

In addition, the pull tab mounting column 6, as described in PCT / JP2009 / 64927, can be mounted on the lower flap 2.

As shown in Figure 2, the Y-shaped tape guide passage 12 guiding the folded section 14a of the U-folded closure tape 14 is configured by the inner end surfaces 21b of the pair of upper plates 3b and 4b and the outer end surface of the first element guidance section 7.

The rear end section of the first element guiding section 7 extends near the connection section of the parallel sections 23a of the side walls 3a and 4a and the enlarged opening 23b.

The passage surrounded by the inner wall surfaces of the pair of flanges 3 and 4, the inner wall surface of the lower flap 2, the guide column 5 and the first element guide section 7 is configured as the guide step of elements 10 guiding the closure element 13 coupled to the closure tape 14.

In addition, the second element guide section 8 is formed on the inner walls of both the left and right ends of the lower fin 2. The second element guide section 8 is a protruding section that projects upward beyond the inner wall. of the lower fin 2 and the projecting section is formed by extending the front end 22 towards the rear opening 17 from the front end edge 2a of the lower fin 2.

The second element guide section 8 extends substantially in parallel in the direction of sliding of the cursor, that is, the front-rear direction and the end of the rear opening side of the second element guidance section 8 is the section which is in contact with the interior wall surface of the enlarged opening 23b of the side walls 3a and 4a.

The second element guiding section 8, as shown in Figures 1 and 3, has an extreme guiding section 8a having a flat surface 24 facing the side walls 3a and 4a and a guiding surface 8b inclined downwards. towards the upper surface of the lower fin 2 from the extreme guide section 8a. The flat surface 24 in the extreme guide section 8a may be configured as a surface that is parallel with the upper surface of the lower fin 2 or a smooth surface inclined downwardly towards the rear opening 17.

The configuration of the guide surface 8b or the extreme guide section 8a in the second element guide section 8 can extend in the axial direction that is parallel to the center line in the left-right direction in the cursor 1 or can extend in the axial direction Inclined towards the center line in the left-right direction, towards the shoulder opening 16 of the cursor 1, when viewed from the plane described above.

That is, the rear end section of the element 13b of the closure element 13 which is guided in sliding contact by the second element guide section 8 is necessary to configure the guiding surface 8b and / or the extreme guide section 8a to be near the center line in the left-right direction at the cursor 1, according to the movement towards the rear opening 17, when viewed from above.

Furthermore, as the position of the front end section in the second element guide section 8, the position of the front end edge 2a of the lower fin 2 is exemplified, that is, a configuration in which the front end section extends further forward than the front end of the guide column 5. However, like the position of the front end section of the second element guide section 8, the front end section may extend to the position of the side of the guide column 5, on one half of the side of the guide column 5 in the front-back direction.

A stepped section 25 is configured at the lower end edge of the downwardly guided guide surface 8b. As shown in Figures 5 and 6, when the closure element 13 is in a horizontal position by the protruding section 29 formed on the upper surface of the lower fin 2, from the stepped section 25 and the guide column 5 to the rear opening 17, the closing element 13 can be lifted from the upper surface of the lower fin 2. The guiding surface 8b can be configured as a flat inclined surface or in a curved shape having a smooth convex curved surface or a surface concave curve

By this configuration, when the closure element 13 is in a horizontal position, it is possible to prevent a thread 27 fixing the closure element 13 to the closure tape 14 from coming into contact with the upper surface of the lower fin 2.

As shown in Figure 6, the connection section from the extreme guide section 8a to the guide surface 8b is configured as a smooth convex curved surface and the connection section from the guide surface 8b to the stepped section 25 is configured as a smooth convex curved surface.

Also, in the invention, it may be possible to eliminate the extreme guide section 8a and extend the guide surface 8b to both left and right sides of the lower fin 2.

As shown in Figure 2, a cord section 28 is formed along the interface between the side walls 3a and 4a and the bottom fin 2 to increase the mounting strength between the side walls 3a and 4a and the bottom fin 2 and formability in training.

Next, a smooth slide of the cursor 1 is described in detail with reference to Figures 5 to 8.

The closure chain for a concealed zip closure shown in Figure 5 is a type that fixes the closure element 13, which is formed in the form of a helix or in the form of a zigzag formed in a line on the closure tape (not shown). ). The linear closure element 13, as shown in Figure 7, is coupled to the folded section of the closure tape 14 which is folded in a U-shape, by a thread 27. The pair of closure elements 13, as shown in Figure 5, it is arranged so that the coupling heads 13a of the closure elements 13 are opposite each other and the opposite sides of the coupling heads 13a are connected by an inverse section.

Figure 5 is a cross-sectional view of the cursor 1 with the upper plates 3b and 4b and the first guiding section of removed elements 7 and shows the closing element 13 introduced in the guiding passage of elements 10 of the lower flap 2 Fig. 6 is an illustrative view showing a change in the position of the closure element 13 introduced in the guiding passage of elements 10 in an upright state, bringing the rear end section of element 13b in sliding contact with the second section of guiding element 8 and the coupling head 13a in sliding contact with the first guiding section of elements 7, in the closing element 13 inserted in the cursor 1.

Figure 7 is a cross-sectional view A-A of Figure 5 and Figure 8 is a cross-sectional view B-B of Figure 5.

As can be understood from Figure 5, the pair of closure bands 15 disposed in front of the shoulder opening 16 of the cursor 1 is widely opened by a large transverse traction force around the front end edge 21 of the pair of upper plates 3b and 4b. The closure element 13 is erected substantially perpendicular to the tape surface of the closure tape 14, with the coupling head 13a facing up.

As the cursor 1 slides in the closing direction (upwards in figure 5), the rear end section of the element 13b of the next closing element 13 sequentially contacts the extreme guide section 8a and / or the surface guide 8b of the second element guide section 8 of the cursor 1. In this process, the closure element 13 which is in sliding contact with the second element guide section 8 is erect with the coupling head 13a facing up, due to the influence of a large transversal traction force applied to the closure tape 14.

Also, as the cursor 1 continues to slide in the closing direction, the moment of rotation that inclines the closing element 13 to a horizontal position from the second element guide section 8 is applied

to the closing element 13. In addition, a torsional force that inclines the next closing element 13 in a horizontal posture is applied through the closing tape 14 from the previous closing element 13 which has been inclined in the horizontal posture and a tensile force is applied that pulls the closure tape 14 on the cursor 1.

The forces are effectively applied to the closure element 13 which is introduced in the cursor 1 and the closure element 13 which is in the upright posture comes into sliding contact with the second element guiding section 8, thus inclining to a posture. horizontal. In addition, as shown in Figure 7, since the coupling head 13a enters more in sliding contact with the front guide surface 7a of the first element guide section 7, the closure element 13 tilts more in a state horizontal. In addition, as shown in Figure 8, the closure element may be in a horizontal posture.

As shown in Figure 6, the closure element 13 that is in the upright posture gradually inclines to a horizontal posture while turning clockwise.

As described above, in the invention, when the closure element 13 in the upright posture is inserted into the cursor 1, the closure element 13 first inclines from the second element guide section 8 to be in a horizontal posture. with respect to the rear end section of element 13b, and then, the closure element 13 is inclined to be in a horizontal position from the first element guide section 7 with respect to the coupling head 13a.

In addition, the pair of lateral guide surfaces 7b in the first element guide section 7 is formed to continue with the front guide surface 7a which is an inclined surface, such that the closure element 13 inclined to a horizontal posture it can be introduced gently into the coupling region of the closure elements.

In addition, as shown in Figure 7, the distance from the front end section of the pair of upper plates 3b and 4b that are in sliding contact with the folded section 14a of the closure tape 14 inserted in the cursor 1 to the extreme section rear 13b of the element is longer than the distance from the front end sections to the coupling head 13a. Using this arrangement configuration, such as the moment of rotation that inclines the closing element 13, a stronger rotation moment can be applied by guiding the rear end section of the element 13b in sliding contact instead of guiding the coupling head 13a in contact. slider

In addition, the starting position of the second element guiding section 8 that begins to guide the rear end section of element 13b in sliding contact is arranged ahead of the starting position of the first element guiding section 7 which begins to guide the coupling head 13a in sliding contact and the starting position of the tape guide passage 10 which begins to guide the folded section 14a of the closing tape 14 in sliding contact.

By this configuration, the rotation time that rotates the closure element 13 in a horizontal position direction can be applied to the rear end section of element 13b from the second element guide section 8 before the coupling head 13a of the closure element 13 is forcedly rotated in a horizontal position direction by the first element guiding section 7 or before the closure tape 14 curves in the longitudinal direction by the leading end edges of the pair of upper plates 3b and 4b.

In addition, the closure element 13 is supported by the second element guide section 8 so that the moment of rotation (of the front guide surface 7a) of the first element guide section 7 is easily applied.

Therefore, the closure tape 14 can be gently inserted into the tape guide passage 12 and the angle of inclination of the closure element 13 can be changed slightly towards the horizontal stance side when the coupling head 13a of the closure element 13 it comes into sliding contact with the first element guidance section 7.

In particular, as shown in Figure 7, when the closure element 13 is sewn and coupled by a thread 27 along the end edge of the closure tape 14, the closure element 13 is not monolphically coupled to the tape closure 14. Therefore, the closure tape 14 under a large transverse traction force can move transversely while generating a movement relative to the closure element 13.

Furthermore, even when the closure tape 14 moves relatively with respect to the closure element 13 by the traction force and the closure element 13 is left in the direction of movement of the closure tape 14, the closure element 13 it moves monolphically in the same direction, with respect to the direction of movement of the closure tape 14 along the tape guide passage 12.

In the movement of the closure tape 14 along the tape guide passage 12, the rear end section of element 13b of the closure element 13 moves in sliding contact with the second array of elements 8. In addition, the head of Coupling 13a of the closure element 13 is moved to the first array of elements 7 by the second array of elements 8 and the coupling head 13a may enter sliding contact with the first array of elements 7.

In addition, the closure element 13 is tilted in a horizontal posture from the position erected by the second element array 8 and the first element array 7.

In the invention described above, since the closure element 13 can be gently inclined to a horizontal posture, it is possible to safely prevent the closure element 13 from being sandwiched to the tape guide passage 12. In addition, the closure element 13 is it glides smoothly in the guiding step of elements 10 and can be safely moved to a predetermined inclined posture for coupling.

That is, the pair of closing elements 13 can surely be changed to a horizontal posture before the pair of opposing closing elements 13 is coupled. Accordingly, the pair of closing elements 13 can be safely coupled and can be avoided with security the so-called prick.

In addition, in the above description, although a configuration is described that uses a chain-shaped closure element as the closure element of a hidden zipper closure, such as the closure element in the invention, is not limited to the closure element. chain-shaped, but as in the invention described in patent document 2, it can be properly applied to a concealed zipper closure with closure elements that are coupled to a closure tape at predetermined intervals. Even in this case, the coupling head with closing elements is raised by the influence of the closing band under a large transversal traction force. However, the coupling head can be guided to lean more towards a horizontal posture in the first element guiding section after the rear end side of the closure elements is first guided to the second element guiding section and inclined. slightly in a horizontal state.

In addition, the closure elements may be inclined in a horizontal state by the second element guidance section and the first element guidance section. As described above, it is possible to prevent with certainty that the closure elements are sandwiched in the guiding passage of the tape or that the so-called puncture is generated in the coupling of a pair of closure elements.

Industrial applicability

The invention can be appropriately used as a cursor for a hidden zipper closure that is coupled to the opening of the seat cover of a seat sheet, fabrics or the like.
