Description

TECHNICAL FIELD The present invention relates to an integrated product of a slide fastener and a resin extruded member that shields a long groove.

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

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 provided at both ends of the upper rail in the sliding movement direction. A connected slider is attached to each. In addition, the pair of groove shielding members are formed with drop-preventing stepped portions, respectively, and these drop-off preventing stepped portions are accommodated in storage portions of protectors (side members) fixed to the lower rail.

In the above-described slide rail device, as the upper rail moves, the slider on the front side in the sliding movement direction of the upper rail releases the engagement of the pair of groove shielding members to open the opening, and the slider on the rear side opens the pair of groove shielding members. groove shielding member 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 kept shielded by the pair of groove shielding members on the front side and the rear side in the sliding direction of the upper rail.

WO2010/067437

By the way, in the slide rail device described in Patent Literature 1, the dropout stepped portions of the pair of groove shielding members are movably stored in the storage portion of the protector. Therefore, when an external force is applied, for example, by stepping on the groove shielding member or the protector, a force is generated that pulls the groove shielding member out of the storage portion of the protector, and the protector is flexed, thereby causing the groove shielding member to move. may come off the protector. For this reason, it is necessary to make the stepped portion of the groove shielding member large enough to prevent it from coming off, or to make the protector thick and made of a highly rigid material so as to withstand the external force.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an integrated product of a slide fastener and a resin extruded profile that can improve the holding force of a fastener chain that shields a groove.

The integrated slide fastener and resin extruded member of the present invention comprises 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). and the side members (40A, 40B) are formed of resin extruded sections insert-molded together with the fastener chains (61A, 61B), and the side members (40A, 40B) are: The upper piece (43) fixed to the upper surface (622A) of the outer edge (622) of the fastener chain (61A, 61B) and the lower surface (622) of the outer edge (622) of the fastener chain (61A, 61B) 622B) and a lower piece (44) affixed thereto.
According to the slide fastener integrated with the resin extruded member of the present invention, the side member is insert-molded together with the fastener chain. A part and a lower piece part are adhered. Therefore, compared to the case where the side member is formed with a storage portion and the fastener chain is formed with a drop-off prevention stepped portion that is movably stored in the storage portion, the holding force of the fastener chain by the side member can be increased. For example, even if the integrated object is stepped on and an external force is applied, the shielding state of the groove can be appropriately maintained.

In the integrated product of the slide fastener and the resin extruded member 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, the width region of the lower piece portion corresponding to the width dimension can be fixed to the fastener chain, and even if the integrated object is stepped on, for example, an external force can be applied. It is possible to increase the holding force of the fastener chain by the side member.

In the slide fastener integrated with the extruded resin profile of the present invention, the fastener chain includes a fastener tape having the side member fixed to the outer edge, and a fastener element attached to the inner edge of the fastener tape. At least a portion of the fastener element may project downward from the fastener tape.
With such a configuration, the fastener element at least partially protruding downward can be used as a guide for conveying the fastener chain in the extrusion direction when the side member is insert-molded together with the fastener chain.

In the integrated product of the slide fastener and the resin extruded member of the present invention, the side member has a plate-like side main body portion and a fixed piece portion extending downward from the side main body portion. The body portion may have the upper piece portion and the lower piece portion, and a reinforcing member may be embedded in the fixed piece portion to reinforce the fixed piece portion.
According to such a configuration, since the reinforcing member is embedded in the fixed piece portion, it is possible to improve the fixing strength when fixing the fixed piece portion of the side member to the base body in which the groove portion is formed.

In the integrated product of the slide fastener and the resin extruded member of the present invention, the width dimension in the left-right direction of the lower piece portion starting from the outer edge surface of the outer edge portion of the fastener chain starts from the outer edge surface. It may be larger than the width dimension in the left-right direction of the upper piece.
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 wider than the side edge of the upper piece. can also be arranged at a position close to the inner edge of the fastener chain, and the fixed portion between the lower side edge of the upper piece and the fastener chain can be supported from below by the lower piece. Therefore, even if an external force (an external force such as a pin heel) is applied from above such as when the fastener chain is stepped on, it is possible to suppress peeling of the upper piece and the fixed portion of the fastener chain.

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

The slide rail device 1 includes a lower rail 20 as a base in which a slide groove 21 (guide groove) is formed, and an upper rail 30 as a moving body arranged movably along the slide groove 21. ), a first side cover 40A and a second side cover 40B as a pair of left and right side members arranged across the opening 211 of the slide groove 21, and held by the first side cover 40A and the second side cover 40B. and a slide fastener 60.

The lower rail 20 is to be embedded in the floor of the automobile, and as shown in FIG. Pieces 23, 24, a pair of upper pieces 25, 26 bent in the Y-axis direction from the upper edges of the side pieces 23, 24, and a pair extending downward from the inner edges of the upper pieces 25, 26 and rail portions 27 and 28. The side pieces 23 and 24 have the same height in the Z-axis direction, and the upper pieces 25 and 26 have the same width in the Y-axis direction. A slide groove 21 is formed by the lower piece 22 , the side pieces 23 and 24 and the upper pieces 25 and 26 , and an opening 211 of the slide groove 21 is formed between the upper pieces 25 and 26 .
End members 11 shown in FIG. 1 are attached to both ends of the lower rail 20 in the X-axis direction. The end member 11 is formed with an engaging piece portion 111 that engages with a later-described fixed piece portion 42 of the first side cover 40A and the second side cover 40B.

The upper rail 30 has, as shown in FIG. As shown in FIG. 1, a first slider 70A and a second slider 70B, which will be described later, are attached to both ends of the attachment portion 31 in the X-axis direction. The rail portion 32 is arranged in the slide groove 21 of the lower rail 20, and is fitted to the rail portions 27 and 28 of the lower rail 20 so as to be able to travel in the X-axis direction.

As shown in FIG. 2, the first side cover 40A has a plate-like side main body portion 41 along the X-axis direction and a fixed piece portion 42 extending downward from the side main body portion 41. It is formed to have a substantially T-shaped cross section.

The side body portion 41 has a width dimension in the Y-axis direction that can cover one of the left and right sides of the slide groove 21 of the lower rail 20 from above. 44 is formed, and between the upper piece portion 43 and the lower piece portion 44, a fixing portion of the fastener tape 62, which will be described later, is arranged. 622 A, and the upper surface 441 of the lower piece portion 44 is adhered to the lower surface 622 B of the outer edge portion 622 of the fastener tape 62 .

A lower edge portion 421 of the fixed piece portion 42 bulges outward in the Y-axis direction. The fixing piece 42 is inserted between the side piece 23 of the lower rail 20 and the engaging piece 111 of the end member 11 to engage with the engaging piece 111 as shown in FIG. The piece 42 is fixed to the lower rail 20 . Further, the fixed piece portion 42 is reinforced by embedding a reinforcing member 422 formed of a metal piece along the Z-axis direction, thereby fixing the fixed piece portion 42 to the lower rail 20 . It is possible to improve the fixing strength when doing.

The first side cover 40A configured in this way is formed of a resin extruded shape member which is insert-molded together with the reinforcing member 422 and a first fastener chain 61A, which will be described later. Since the first side cover 40A is insert-molded in this way, the reinforcing member 422 can be easily embedded, and the upper piece 43 and the lower piece 44 can be easily fixed to the first fastener chain 61A with high strength.

The second side cover 40B is configured in the same manner as the first side cover 40A, is arranged with the left and right sides reversed, and is fixed to a second fastener chain 61B, which will be described later. and detailed description thereof will be omitted.

As shown in FIGS. 1 and 2, the slide fastener 60 consists of a first fastener chain 61A and a second fastener chain 61B as a pair of left and right fastener chains respectively held by the first side cover 40A and the second side cover 40B. , a first slider 70A attached to one end of the upper rail 30 in the X-axis direction, and a second slider 70B attached to the other end of the upper rail 30 in the X-axis direction. The first slider 70A and the second slider 70B are configured similarly to each other and are arranged in pairs in the X-axis direction.

The first fastener chain 61A is attached to the fastener tape 62 arranged to cover the opening 211 of the slide groove 21 and the inner edge 621 of the fastener tape 62 along the X-axis direction, and is attached to the first slider 70A and the first slider 70A. and a fastener element 65 to which the second slider 70B is slidably connected. In this 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 continuous in the X-axis direction in a coil shape. Although it is formed, it is not limited to this, and can be configured by various tapes and elements.
At least a part of the fastener element 65 is arranged so as to protrude downward from the fastener tape 62 . Therefore, when conveying the first fastener chain 61A and the second fastener chain 61B in the extrusion direction 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, A fastener element 65, at least a part of which projects downward, can be used as a guide.

In the fastener tape 62, the upper surface 622A and the lower surface 622B of the outer edge portion 622 located outside in the Y-axis direction with respect to the inner edge portion 621 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 this 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 slide rail device 1 described above, the slide groove shield 10 includes a pair of left and right first fastener chains 61A and second fastener chains 61B, and a pair of left and right second fastener chains 61A and 61B each holding the first fastener chains 61A and second fastener chains 61B. It is composed of one side cover 40A and a second side cover 40B.
The form of the first side cover 40A in the slide groove shield 10 will be described below with reference to FIG. The second side cover 40B can also be constructed in the same manner as the first side cover 40A.

In FIG. 3A, the width dimension in the Y-axis direction of the upper piece portion 43 and the lower piece portion 44 of the first side cover 40A, here, the width dimension W1 starting from the outer edge surface 622C of the first fastener chain 61A , W2 have the same dimensions. Therefore, side edges 432 and 442 along the X-axis direction of the upper piece portion 43 and the lower piece portion 44 are arranged along a virtual plane defined in the X-axis direction and the Z-axis direction. Also, 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. Furthermore, the width dimensions W1 and W2 are set to 8 mm here, so that the first side is sufficiently tolerable even if an external force is 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 chamfering), and the upper surface 441 and the side edge 442 of the lower piece portion 44 are continuous. A corner portion 443 is also chamfered (here, R-chamfered). Of the portion of the upper surface 441 of the lower piece 44 fixed to the first fastener chain 61A, the portion P1 located on the innermost edge 621 side is It is located on the inner edge 621 side with a difference C in the Y-axis direction from the site P2 closest to the inner edge 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 . In addition, since the portion P1 is positioned closer to the inner edge portion 621 of the first fastener chain 61A than the portion P2, the portion P1 can be supported by the lower piece portion 44 from below. Therefore, even if the first fastener chain 61A and the second fastener chain 61B are stepped on and an external force (external force such as a pin heel) is applied from above, the first fastener chain 61A and the second fastener chain 61B will remain on the upper side. To increase the fixing strength by changing the stress applied to the fixing surface between the first fastener chain 61A and the second fastener chain 61B and the upper piece part 43 from "peeling" to "shearing" while suppressing peeling downward from the part 43. can be done. In this way, it is possible to suppress peeling of the fixed portion of the upper piece portion 43 of the first side cover 40A and the first fastener chain 61A, and fixation of the upper piece portion 43 of the second side cover 40B and the second fastener chain 61B. It is possible to suppress peeling at the part.
Although the corners 433 and 443 are chamfered here, they may not be chamfered. Even in this case, since the first side cover 40A and the second side cover 40B are fixed together with the first fastener chain 61A and the second fastener chain 61B by insert molding, it is possible to obtain necessary and sufficient fixing strength.

In FIG. 3B, the width dimension W2 of the lower piece portion 44 is 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 can be set to the upper piece portion. 43 can be arranged at a position closer to the inner edge 621 of the first fastener chain 61A than the side edge 432 of the first fastener chain 61A, and the fixed portion between the lower side edge 432 of the upper piece 43 and the first fastener chain 61A is secured by the lower piece 44. It can be supported from below. As a result, even if the first fastener chain 61A and the second fastener chain 61B are stepped on, for example, and an external force (external force such as a pin heel) is applied from above, the upper pieces of the first side cover 40A and the second side cover 40B are prevented from moving. It is possible to suppress peeling at the fixed portions between the portion 43 and the first fastener chain 61A and the second fastener chain 61B.
The width W1 of the upper piece 43 is 6 mm, the width W2 of the lower piece 44 is 10 mm, and the thicknesses T1 and T2 are the same as in FIG. 3A. For this reason, the cross-sectional area of the upper piece 43 of FIG. 3(B), which is reduced as the width dimension W1 becomes smaller than that of the upper piece 43 of FIG. 3(A), is The lower piece portion 44 of FIG. 3A has the same area as the cross-sectional area increased according to the increase in the width dimension W2 compared to the lower piece portion 44 of FIG. 3A. Therefore, as shown in FIG. 3(B), when the width dimension W2 is increased and the width dimension W1 is decreased, the cross-sectional area is smaller than when the width dimensions W1 and W2 are the same. increase can be suppressed.

In FIG. 3C, the width dimension W2 of the lower piece 44 is the same as the width dimension W2 shown in FIG. ) has a thickness T3 smaller than the thickness T1, and the width W1 of the upper piece 43 is larger than the width W1 shown in FIG. 3B.
Even if the width dimension W1 of the upper piece portion 43 is increased in this way to enlarge the fixed area, the portion having the thickness dimension T3 is formed in the upper piece portion 43 to reduce the thickness, so the thickness is reduced as shown in FIG. 3(B). An increase in cross-sectional area can be suppressed compared to the first side cover 40A. Further, by thinning the upper piece 43, it is possible to improve the ability to follow the bending deformation of the first fastener chain 61A in the X-axis direction, thereby making it difficult for the first fastener chain 61A to peel off.

In FIG. 3D, the width dimension W2 of the lower piece portion 44 is larger than the width dimension W1 of the upper piece portion 43. As shown in FIG. A side edge 432 of the upper piece portion 43 is formed as an inclined surface (tapered surface) inclined obliquely downward with respect to the Y-axis direction from the bottom surface 46 side toward the inner edge portion 621 side. A side edge 442 of the lower piece portion 44 is an inclined surface (tapered surface) that is inclined 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 area can be increased without increasing the cross-sectional areas of the upper piece portion 43 and the lower piece portion 44 .
