Description

The present invention relates to an integral body of a slide fastener and a resin extruded profile that shields a long groove.

Conventionally, a slide rail device composed of a lower rail (base) fixed to the vehicle body side and an upper rail (upper rail (moving body)) fixed to the seat side is known ( See Patent Document 1). The lower rail is formed with a guide groove (slide groove (groove portion)) through which the upper rail can slide and move.

In this slide rail device, the opening of the guide groove is covered with a pair of left and right groove shielding members (fastener chains) that can be engaged with each other, and a pair of groove shielding members are formed at both ends of the upper rail in the slide moving direction. Each connected slider is attached. Further, each of the pair of groove shielding members is formed with a stepped portion for preventing falling off, and these stepped portions for preventing falling off are housed in a storage portion of a protector (side member) fixed to the lower rail.

In the slide rail device described above, as the upper rail moves, the sliders on the front side in the slide movement direction of the upper rail disengage the pair of groove shielding members to open the opening, and the sliders on the rear side are paired. Engage the groove shielding member of the above to shield the opening. Since the opening of the guide groove is opened and closed in this way, the opening of the guide groove is maintained in a shielded state shielded by the pair of groove shielding members on the front side and the rear side in the sliding movement direction of the upper rail.

International Publication No. 2010/067437

By the way, in the slide rail device described in Patent Document 1, the drop-off step portion of the pair of groove shielding members is movably stored in the storage portion of the protector. Therefore, when an external force is applied, for example, when the groove shielding member or the protector is stepped on, a force is generated in which the groove shielding member is pulled out from the storage portion of the protector, and the protector is bent, so that the groove shielding member is bent. May come off the protector. For this reason, it is necessary to form a large step portion for preventing the groove shielding member from falling off, or to form the protector thickly with a highly rigid material so as to withstand an external force.

An object of the present invention is to provide an integral body of a slide fastener and a resin extruded profile that can improve the holding force of a fastener chain that shields a groove.

The one piece of the slide fastener and the resin extruded profile of the present invention includes a pair of left and right fastener chains (61A, 61B) and a pair of left and right side members (40A, 40B) holding the pair of fastener chains (61A, 61B). The side members (40A, 40B) are formed of a resin extruded profile that is insert-molded together with the fastener chains (61A, 61B), and the side members (40A, 40B) are formed of the side members (40A, 40B). The upper piece (43) fixed to the upper surface (622A) at the outer edge (622) of the fastener chain (61A, 61B) and the lower surface (622) at the outer edge (622) of the fastener chain (61A, 61B). It is characterized by having a lower piece portion (44) fixed to 622B).
According to the one piece of the slide fastener and the resin extruded profile of the present invention, since the side member is insert-molded together with the fastener chain, the upper piece of the side member with respect to the upper surface and the lower surface at the outer edge portion of the fastener chain. The part and the lower piece are fixed. For this reason, the holding force of the fastener chain by the side member can be enhanced as compared with the case where the storage portion is formed in the side member and the fall-prevention step portion movably stored in the storage portion is formed in the fastener chain. For example, even if an external force is applied such as when the one piece is stepped on, the shielded state of the groove can be appropriately maintained.

In the one piece of the slide fastener and the extruded resin profile of the present invention, the lower piece portion may have a width dimension of at least 8 mm in the left-right direction.
According to such a configuration, it can be fixed to the fastener chain in the width region of the lower piece corresponding to the width dimension, and can sufficiently withstand an external force such as when the one piece is stepped on. The holding force of the fastener chain by the side member can be increased.

In the integrated body of the slide fastener and the resin extruded profile of the present invention, the fastener chain has a fastener tape having the side member fixed to the outer edge portion and a fastener element attached to the inner edge portion of the fastener tape. The fastener element may be arranged so that at least a part thereof protrudes below the fastener tape.
According to such a configuration, a fastener element having at least a part protruding downward can be used as a guide when the fastener chain is conveyed in the extrusion direction when the side member is insert-molded together with the fastener chain.

In the integrated body of the slide fastener and the resin extruded profile of the present invention, the side member has a plate-shaped side main body portion and a fixed piece portion extending downward from the side main body portion, and the side member. The main body portion has the upper piece portion and the lower piece portion, and a reinforcing member for reinforcing the fixed piece portion may be embedded inside the fixed piece portion.
According to such a configuration, since the reinforcing member is embedded in the fixing piece portion, the fixing strength when fixing the fixing piece portion of the side member to the substrate on which the groove portion is formed can be improved.

In the integrated product of the slide fastener and the resin extruded profile of the present invention, the width dimension of the lower piece portion in the left-right direction starting from the outer edge surface at the outer edge portion of the fastener chain starts from the outer edge surface. It may be larger than the width dimension of the upper piece portion in the left-right direction.
According to such a configuration, the fixing region of the lower piece to the fastener chain can be made wider than the fixing region of the upper piece, and the side edge of the lower piece along the groove is set from the side edge of the upper piece. Can be arranged at a position close to the inner edge of the fastener chain, and the portion where the lower side edge of the upper piece and the fastener chain are fixed can be supported from below by the lower piece. Therefore, even if an external force (external force such as a stiletto heel) is applied from above, for example, when the fastener chain is trampled, peeling at the upper piece portion and the fixed portion of the fastener chain can be suppressed.

According to the present invention, it is possible to provide an integral product of a slide fastener and a resin extruded profile that can improve the holding force of a fastener chain that shields a groove.

In the present embodiment, the fastener tape 62 is formed in a tape shape along the X-axis direction by a net structure in which resin threads are woven, and the fastener element 65 is formed by a coil element that is coiled in the X-axis direction. Although it is formed, it is not limited to this, and can be configured by various tapes and elements.
Further, at least a part of the fastener element 65 is arranged so as to project downward from the fastener tape 62. Therefore, when the first side cover 40A and the second side cover 40B are insert-molded together with the first fastener chain 61A and the second fastener chain 61B, the first fastener chain 61A and the second fastener chain 61B are conveyed in the extrusion direction. As a guide for the fastener element 65, at least a part of which protrudes downward can be used.

In the fastener tape 62, the upper surface 622A and the lower surface 622B of the outer edge portion 622 located outside the inner edge portion 621 in the Y-axis direction are fixed to the lower surface 431 of the upper piece portion 43 and the upper surface 441 of the lower piece portion 44. .. Further, in the present embodiment, the outer edge surface 622C of the outer edge portion 622 of the fastener tape 62 is fixed to the bottom surface 46 of the fixing groove 45 formed between the upper piece portion 43 and the lower piece portion 44.

In the above slide rail device 1, the slide groove shield 10 has a pair of left and right first fastener chains 61A and a second fastener chain 61B, and a pair of left and right fastener chains 61A and a second fastener chain 61B, respectively. It is composed of one side cover 40A and a second side cover 40B.
Hereinafter, the form of the first side cover 40A in the slide groove shield 10 will be described with reference to FIG. The second side cover 40B can be configured in the same manner as the first side cover 40A.

In FIG. 3A, the width dimension of the upper piece portion 43 and the lower piece portion 44 of the first side cover 40A in the Y-axis direction, here, the width dimension W1 starting from the outer edge surface 622C of the first fastener chain 61A. , W2 have the same dimensions as each other. Therefore, the side edges 432 and 442 of the upper piece portion 43 and the lower piece portion 44 along the X-axis direction are arranged along the virtual surfaces defined in the X-axis direction and the Z-axis direction. Further, the thickness dimensions T1 and T2 of the upper piece portion 43 and the lower piece portion 44 in the Z-axis direction are the same as each other. Further, the width dimensions W1 and W2 are set to 8 mm here, so that the first side can sufficiently withstand an external force applied from above, for example, when the slide groove shield 10 is stepped on. The holding force of the first fastener chain 61A and the second fastener chain 61B by the cover 40A and the second side cover 40B can be increased.
Here, the corner portion 433 where the lower surface 431 and the side edge 432 of the upper piece portion 43 are continuous is chamfered (here, R chamfer), and the upper surface 441 and the side edge 442 of the lower piece portion 44 are continuous. The corner portion 443 is also chamfered (here, R chamfered). The portion P1 on the innermost edge portion 621 side of the portion of the upper surface 441 of the lower piece portion 44 fixed to the first fastener chain 61A is the portion of the lower surface 431 of the upper piece portion 43 fixed to the first fastener chain 61A. It is located on the inner edge portion 621 side with a difference C in the Y-axis direction from the portion P2 on the innermost edge portion 621 side. Therefore, the fixing region of the lower piece portion 44 to the first fastener chain 61A can be made wider than the fixing region of the upper piece portion 43. Further, since the portion P1 is located closer to the inner edge portion 621 of the first fastener chain 61A than the portion P2, the portion P1 can be supported from below by the lower piece portion 44. Therefore, even if an external force (external force such as a pin heel) is applied from above by, for example, the first fastener chain 61A and the second fastener chain 61B being trampled, the first fastener chain 61A and the second fastener chain 61B are on the upper piece. While suppressing downward peeling from the portion 43, the stress applied to the bonding surface between the first fastener chain 61A and the second fastener chain 61B and the upper piece portion 43 can be changed from "peeling" to "shearing" to increase the fixing strength. Can be done. In this way, peeling of the upper piece 43 of the first side cover 40A and the fixed portion of the first fastener chain 61A can be suppressed, and the upper piece 43 of the second side cover 40B and the second fastener chain 61B are fixed. It is possible to suppress peeling in the portion.
Here, the corner portions 433 and 443 are chamfered, but the chamfering may not be performed. Even in this case, since the first side cover 40A and the second side cover 40B are insert-molded and fixed together with the first fastener chain 61A and the second fastener chain 61B, it is possible to obtain the necessary and sufficient fixing strength.

In FIG. 3B, the width dimension W2 of the lower piece portion 44 is made larger than the width dimension W1 of the upper piece portion 43. Therefore, the fixing region of the lower piece portion 44 to the first fastener chain 61A can be made wider than the fixing region of the upper piece portion 43, and the side edge 442 of the lower piece portion 44 along the X-axis direction is formed as the upper piece portion. It can be arranged closer to the inner edge portion 621 of the first fastener chain 61A than the side edge 432 of 43, and the portion where the lower side edge 432 of the upper piece portion 43 and the first fastener chain 61A are fixed to each other is formed by the lower piece portion 44. Can be supported from below. As a result, even if an external force (external force such as a stiletto heel) is applied from above, for example, the first fastener chain 61A and the second fastener chain 61B are trampled, the upper piece of the first side cover 40A and the second side cover 40B. It is possible to suppress peeling at the portion where the portion 43 and the first fastener chain 61A and the second fastener chain 61B are fixed.
Further, the width dimension W1 of the upper piece portion 43 is 6 mm, the width dimension W2 of the lower piece portion 44 is 10 mm, and the thickness dimensions T1 and T2 are the same dimensions as in FIG. 3A. Therefore, the cross-sectional area of the upper piece portion 43 of FIG. 3 (B) is reduced according to the smaller width dimension W1 as compared with the upper piece portion 43 of FIG. 3 (A). The lower piece portion 44 has the same area as the cross-sectional area increased according to the increase in the width dimension W2 as compared with the lower piece portion 44 in FIG. 3 (A). Therefore, as shown in FIG. 3B, when the amount of increasing the width dimension W2 and the amount of decreasing the width dimension W1 are the same, the cross-sectional area is compared with the case where the width dimensions W1 and W2 are the same. Can be suppressed.

In FIG. 3C, the width dimension W2 of the lower piece portion 44 is the same as the width dimension W2 shown in FIG. 3B, but the upper piece portion 43 has its side edge 432 to the bottom surface 46 (outer edge surface 622C). ) Is set to a thickness dimension T3 smaller than the thickness dimension T1, and the width dimension W1 of the upper piece portion 43 is larger than the width dimension W1 shown in FIG. 3 (B).
Even if the width dimension W1 of the upper piece portion 43 is increased to increase the fixing area in this way, a portion having a thickness dimension T3 is formed on the upper piece portion 43 to reduce the wall thickness. It is possible to suppress an increase in the cross-sectional area as compared with the first side cover 40A of the above. Further, by thinning the upper piece portion 43, it is possible to improve the followability of the first fastener chain 61A to bending deformation in the X-axis direction, and it is possible to make the structure difficult to peel off.

In FIG. 3D, the width dimension W2 of the lower piece portion 44 is made larger than the width dimension W1 of the upper piece portion 43. The side edge 432 of the upper piece portion 43 is an inclined surface (tapered surface) inclined diagonally downward with respect to the Y-axis direction from the bottom surface 46 side toward the inner edge portion 621 side. The side edge 442 of the lower piece portion 44 is an inclined surface (tapered surface) inclined diagonally upward with respect to the Y-axis direction from the bottom surface 46 side toward the inner edge portion 621 side. By forming the side edges 432 and 442 as inclined surfaces in this way, the fixing region can be increased without increasing the cross-sectional area of the upper piece portion 43 and the lower piece portion 44.
