Description

[Technical field]

[0001] The present invention relates to a slide rail structure and a manufacturing method thereof. [Background technology]

[0002] 11 shows a conventional slide rail structure 1 and a vehicle box device 2 in which the structure 1 is used. The slide rail structure 1 has a pair of left and right guide rails 4 provided on a box 3 and extending in the rail longitudinal direction, and a pair of left and right slide protrusions 6 provided on a door 5 and supported by the pair of guide rails 4 so as to be slidable in the rail longitudinal direction.

[0003] The guide rail 4 has a U-shaped cross section so that the slide protrusion 6 slides in the longitudinal direction of the rail and so that the slide protrusion 6 does not come off the guide rail 4 in a direction perpendicular to the longitudinal direction of the rail.

[0004] Because the guide rails 4 have a U-shaped cross section, resulting in an undercut, it is difficult to mold the pair of guide rails 4 integrally with the box 3, and so they are made into separate parts. As a result, the number of parts, including the parts for attaching the guide rails 4 to the box 3, is large for the slide rail structure 1 and the device 2 in which the structure 1 is used.

[0005] In order to reduce the number of parts, it is possible to devise a mold structure and use a slide mold for undercut molding. However, when the slide mold slides, space for the mold structure (space for the thickness of the slide mold plus the distance the slide mold moves) is required. Therefore, depending on the shape of the periphery of the guide rail 4, the slide mold structure may not be viable, or even if it is viable, the mold may become too large, resulting in high mold costs.

Effect of the Invention

[0009] According to the slide rail structure described above in (1), the following effects can be obtained. Since the guide rail has a base portion that is molded integrally with the first member, the base portion can be molded integrally with the first member. Also, since the base portion and the movable portion are connected by an integral hinge, the base portion and the movable portion can be molded integrally. Therefore, the first member and the pair of guide rails can be molded integrally, and the number of parts of the slide rail structure and the device in which the structure is used can be reduced compared to when the first member and the pair of guide rails are molded separately.

[0010] In addition, because the movable part is rotatable about the integral hinge with respect to the base part from a molding position where the other side part does not face the one side part to a use position where the other side part faces the one side part, the guide rail with the movable part in the molding position can be molded integrally with the first member, and then the movable part can be rotated about the integral hinge with respect to the base part from the molding position to the use position. With this structure, the guide rail can be molded integrally with the first member while avoiding a state in which the guide rail is undercut, and the guide rail can be molded without requiring a slide mold.

[0011] According to the slide rail structure of (2) above, the following effects can be obtained. Since the base portion has a stopper portion which abuts when the movable part is in the use position and prevents the movable part from rotating beyond the use position when the movable part is rotated around the integral hinge from the molding position to the use position, the movable part can be prevented from rotating beyond the use position when the movable part is rotated around the integral hinge from the molding position to the use position.

[0012] According to the slide rail structure of (3) above, the following effects can be obtained. Since the stopper portion extends from one side toward the other side of the movable part when it is in the use position, the movable part can be abutted against the stopper portion when the movable part is rotated around the integral hinge from the molding position to the use position, and the stopper portion can prevent the movable part from rotating beyond the use position.

[0013] In addition, one side of the base portion and the stopper portion, and the other side of the movable portion when in the usage position, have a C-shape in a cross-sectional view perpendicular to the longitudinal direction of the rail to accommodate the slide protrusion in the inner space. Therefore, the base portion and the movable portion can support the slide protrusion so that it can slide in the longitudinal direction of the rail, and can prevent the slide protrusion from coming off the guide rail in a direction perpendicular to the longitudinal direction of the rail.

[0014] Furthermore, when the movable part is in the usage position, the movable part abuts both the outer surface and the extending end surface of the stopper part. Therefore, unlike a case in which the movable part only contacts the outer surface of the stopper part and does not abut the extending end surface of the stopper part, even when the movable part is connected to the base part by an integral hinge, the distance between one side of the base part and the other side of the movable part in the usage position can be a predetermined distance.

[0015] According to the slide rail structure of (4) above, the following effects can be obtained. A claw portion is provided on one of the base portion and the movable portion, and a claw receiving portion is provided on the other of the base portion and the movable portion with which the claw portion engages when the movable portion is in the usage position, thereby preventing the movable part in the usage position from rotating around the integral hinge toward the molding position. Therefore, by engaging the claw portion with the claw receiving portion, the movable part in the usage position can be prevented from rotating around the integral hinge toward the molding position.

[0016] According to the slide rail structure of (5) above, the following effects can be obtained. The other side portion of the movable part, the other side opposing portion and the connecting portion have a C-shape in a cross section perpendicular to the longitudinal direction of the rail to receive the sliding protrusion when the movable part is in the usage position in the inner space. Therefore, the other side portion of the movable part, the other side opposing portion and the connecting portion can support the sliding protrusion so that it can slide in the longitudinal direction of the rail, and can prevent the sliding protrusion from coming off the guide rail in a direction perpendicular to the longitudinal direction of the rail.

[0017] According to the slide rail structure of (6) above, the following effects can be obtained. Since the other side opposing portion of the movable part abuts against one side of the base part when the movable part is in the use position, when the movable part is rotated around the integral hinge from the molding position to the use position, the movable part can be prevented from rotating beyond the use position.

[0018] According to the manufacturing method of the slide rail described above in (7), the following effects can be obtained. The method includes a molding process using a mold to integrally mold a guide rail having a base portion, a movable portion at a molding position, and an integral hinge connecting the base portion and the movable portion with the first member, so that the first member and the pair of guide rails can be molded integrally, and the number of parts of the slide rail structure and the device in which the structure is used can be reduced compared to when the first member and the pair of guide rails are molded separately. In addition, since the method includes a rotation step of rotating the movable part from the molding position to the use position about the integral hinge relative to the base part, after the guide rail in which the movable part is in the molding position is integrally molded with the first member, the movable part can be rotated from the molding position to the use position about the integral hinge relative to the base part. Therefore, the guide rail can be integrally molded with the first member while avoiding a state in which the guide rail is undercut, and the guide rail can be molded without requiring a slide mold.

[0019] According to the manufacturing method of the slide rail described above in (8), the following effects can be obtained. In the molding process, molding is performed using a core mold and a cavity mold without using a slide mold, so that the guide rail can be molded without the need for a slide mold.

[0020] According to the manufacturing method of the slide rail described above in (9), the following effects can be obtained. In the molding process, the cavity portion of the mold that molds the other side of the movable part extends in the demolding direction of the core mold relative to the cavity mold, so that in the molding process, the guide rail can be molded using the core mold and the cavity mold without using a slide mold.

[0022] A slide rail structure 10 according to an embodiment of the present invention and a manufacturing method thereof will be described below with reference to the drawings.

[0023] 1 to 8 show a slide rail structure and a manufacturing method thereof according to a first embodiment of the present invention, and Fig. 9 and Fig. 10 show a slide rail structure and a manufacturing method thereof according to a second embodiment of the present invention. Parts that are common or similar to all the embodiments of the present invention are given the same reference numerals as in all the embodiments of the present invention. First, the parts that are common to all the embodiments of the present invention will be described.

[0024] [Slide rail structure] 1, a slide rail structure 10 according to an embodiment of the present invention is a structure that allows a second member 120 to slide relative to a first member 110. The slide rail structure 10, the first member 110 and the second member 120 are components of an apparatus 100 in which the slide rail structure 10 is used.

[0025] The device 100 is not particularly limited, but may be, for example, a box device such as a vehicle accessory storage device having a box and a door that serves to hide the inside of the box, or a console box device for a vehicle. In this case, the first member 110 is a box having a storage section 111 that opens toward the interior of the vehicle, and the second member 120 is a door that slides to open and close the storage section 111 of the first member 110. However, the device 100 does not have to have a box and a door as long as the box itself is a sliding device, or the device has a sliding component such as a sliding cup holder.

[0026] The slide rail structure 10 has a pair of guide rails 20 provided on a first member 110 and extending in the rail longitudinal direction L, and a pair of slide protrusions 30 provided on a second member 120 and respectively held on the pair of guide rails 20 so as to be slidable in the rail longitudinal direction L. The rail longitudinal direction L may be linear as shown in Fig. 4, or may be arcuate as shown in Fig. 6.

[0027] 1, the pair of guide rails 20 are provided on both sides of the first member 110 in the width direction perpendicular to the rail longitudinal direction L. As shown in Fig. 2 and Fig. 9, each of the pair of guide rails 20 has a base part 21 having one side part 21a located on one side of the slide protrusion 30 (first member 110 side, lower side) and integrally molded with the first member 110, a movable part 22 having another side part 22a that can be located on the other side of the slide protrusion 30 (opposite side to the first member 110, upper side), and an integral hinge 23 connecting the base part 21 and the movable part 22.

[0028] One side 21a of the base 21 is provided to extend from or near the opening 111a of the storage section 111 of the first member 110 in a direction to increase the opening area of ​​the storage section 111. One side 21a of the base 21 is provided to extend in a direction perpendicular to a direction L2 in which an object (not shown) is put into or taken out of the storage section 111.

[0029] The movable part 22 is rotatable around the integral hinge 23 with respect to the base part 21 from a molding position 22-1 in which the other side part 22a does not face one side part 21a of the base part 21 (does not extend in a parallel direction) to a use position 22-2 in which the other side part 22a faces one side part 21a (extends in a parallel direction).

[0030] When the movable part 22 is at the molding position 22-1, the other side part 22a extends in the insertion / removal direction L2, i.e., in a direction perpendicular to the extension direction of one side part 21a of the base part 21, and is in a position not facing the one side part 21a. When the movable part 22 is at the use position 22-2 rotated around the integral hinge 23 from the molding position 22-1, the other side part 22a extends in a direction perpendicular to the insertion / removal direction L2, i.e., in a direction parallel to the extension direction of one side part 21a of the base 21, and is in a position facing the one side part 21a.

[0031] The integral hinge 23 is a portion that is thinner than the base portion 21 and the movable portion 22 .

[0032] [Manufacturing method of slide rail structure] The manufacturing method of the slide rail structure 10 includes the steps of: (i) a molding process of integrally molding (injection molding) the guide rail 20 having the base portion 21, the movable portion 22 at the molding position 22-1, and the integral hinge 23 connecting the base portion 21 and the movable portion 22 with the first member 110 using a mold 200 (FIGS. 5 and 10); (ii) a rotating step of rotating the movable part 22 around the integral hinge 23 relative to the base part 21 from the molding position 22-1 to the use position 22-2 (FIGS. 2 and 9); in that order. However, in the mold structure in Figure 10, parts corresponding to the mold structure in Figure 5 are given reference numbers with a prime mark, and in this specification, only the reference numbers without a prime mark will be used for explanation.

[0033] Regarding the molding process (i) above (ia) The mold 200 has a core mold 201 and a cavity mold 202, but does not have a slide mold. Therefore, in the molding process, molding is performed using the core mold 201 and the cavity mold 202 without using a slide mold. (ib) When molding the movable part 22 at the molding position 22-1, the cavity portion 203 for molding the other side part 22a of the movable part 22, which is formed in the mold 200, extends in the demolding direction of the core mold 201 relative to the cavity mold 202. This demolding direction is parallel to the insertion / removal direction L2. (ic) The material of the first member 110 and the guide rail 20 is a thermoplastic resin, and in order to prevent damage when the movable part 22 of the guide rail 20 is rotated around the integral hinge 23 relative to the base part 21 after molding, PP (polypropylene) resin is used instead of ABS (acrylonitrile butadiene styrene) resin.

[0034] Here, the actions and effects common to all the embodiments of the present invention will be described. (A) Since the guide rail 20 has the base portion 21 that is molded integrally with the first member 110, the base portion 21 can be molded integrally with the first member 110. Furthermore, since the base portion 21 and the movable portion 22 are connected by an integral hinge 23, the base portion 21 and the movable portion 22 can be molded integrally. Therefore, the first member 110 and the pair of guide rails 20 can be molded integrally, and the number of parts of the slide rail structure 10 and the device 100 in which the structure is used can be reduced compared to when the first member 110 and the pair of guide rails 20 are molded separately.

[0035] (B) Since the movable part 22 is rotatable about the integral hinge 23 with respect to the base part 21 from a molding position 22-1 where the other side part 22a does not face one side part 21a of the base 21 to a use position 22-2 where the other side part 22a faces the one side part 21a, the guide rail 20 with the movable part 22 at the molding position 22-1 can be integrally molded with the first member 110, and then the movable part 22 can be rotated about the integral hinge 23 with respect to the base part 21 from the molding position 22-1 to the use position 22-2. With this structure, the guide rail 20 can be integrally molded with the first member 110 while avoiding a state where the guide rail 20 is undercut, and the guide rail 20 can be molded without requiring a slide mold.

[0036] (C) Since the mold 200 is used to integrally mold the guide rail 20 having the base portion 21, the movable portion 22 at the molding position 22-1, and the integral hinge 23 connecting the base portion 21 and the movable portion 22, with the first member 110, the first member 110 and the pair of guide rails 20 can be integrally molded, and the number of parts of the slide rail structure 10 and the device 100 in which the structure is used can be reduced compared to when the first member 110 and the pair of guide rails 20 are molded separately.

[0037] (D) Since the method includes a rotation process of rotating the movable part 22 from the molding position 22-1 to the use position 22-2 about the integral hinge 23 relative to the base part 21, after the guide rail 20 at the molding position 22-1 is integrally molded with the first member 110, the movable part 22 can be rotated from the molding position 22-1 to the use position 22-2 about the integral hinge 23 relative to the base part 21. Therefore, the guide rail 20 can be integrally molded with the first member 110 while avoiding a state in which the guide rail 20 is undercut, and the guide rail 20 can be molded without requiring a slide mold.

[0038] (E) In the molding step, molding is performed using the core mold 201 and the cavity mold 202 without using a slide mold, so that the guide rail 20 can be molded without the need for a slide mold.

[0039] (F) In the molding process, since the cavity portion 203 of the mold 200 which molds the other side portion 22a of the movable portion 22 extends in the mold-pulling direction of the core mold 201 relative to the cavity mold 202, in the molding process, the guide rail 20 can be molded using the core mold 201 and the cavity mold 202 without using a slide mold.

[0040] Next, the specific features of each embodiment of the present invention will be described.

[0041] [Example 1] (Figs. 1 to 8) The first embodiment of the present invention is as follows. As shown in FIG. 2, in addition to the one side portion 21a, the base portion 21 further has a stopper portion 21b which abuts against the movable portion 22 when the movable portion 22 is in the use position 22-2 and prevents the movable portion 22 from rotating beyond the use position 22-2 when the movable portion 22 is rotated around the integral hinge 23 from the molding position 22-1 to the use position 22-2.

[0042] The stopper portion 21b is provided extending a predetermined distance from the middle of the one side portion 21a in the extending direction toward the other side portion 22a of the movable portion 22 when in the use position 22-2. The one side portion 21a and the stopper portion 21b of the base portion 21 and the other side portion 22a of the movable portion 22 when in the use position 22-2 are U-shaped in a cross section perpendicular to the rail longitudinal direction L to receive the slide protrusion 30 in the inner space S.

[0043] When the movable part 22 is in the use position 22-2, the movable part 22 abuts against both the outer side surface 21b1 and the extension direction tip surface 21b2 of the stopper part 21b of the base part 21. When the movable part 22 is in the use position 22-2, the movable part 22 abuts against the outer side surface 21b1 of the stopper part 21b at the ribs 22c provided intermittently in the rail longitudinal direction L, and abuts against the extension direction tip surface 21b2 of the stopper part 21b at the other side part 22a. The outer side surface 21b1 of the stopper part 21b is located on the back side (opposite side) of the inner side surface 21b3 that faces the inner space S of the U-shape, and is a surface that does not face the inner space S of the U-shape.

[0044] As shown in FIG. 3, a claw portion 24 is integrally formed on one of the base portion 21 and the movable portion 22, and a claw receiving portion 25 is integrally formed on the other of the base portion 21 and the movable portion 22. When the movable portion 22 is in the usage position 22-2, the claw portion 24 engages with the claw portion 25, thereby restricting the movable portion 22 in the usage position 22-2 from rotating around the integral hinge 23 toward the molding position 22-1.

[0045] The claw portion 24 engages with the claw receiving portion 25 by elastically deforming and restoring at least one of the claw portion 24 and the claw receiving portion 25 when pressed by the other. The direction of this elastic deformation and restoration may be a direction perpendicular to the rail longitudinal direction L, such as the insertion / removal direction L2, as shown in Fig. 3, or may be a direction parallel to the rail longitudinal direction L, as shown in Figs. 7 and 8.

[0046] The engagement structure between the claw portion 24 and the claw receiving portion 25 is provided only in a part of the rail longitudinal direction L, and is provided at least in three places at both ends and the center in the rail longitudinal direction L in order to stabilize the dimensions of the U-shaped shape that receives the slide protrusion 30 in the inner space S and enable smooth sliding of the slide protrusion 30. However, if the length in the rail longitudinal direction L is relatively long and the setting points for the engagement structure between the claw portion 24 and the claw receiving portion 25 can be secured, it is desirable to provide four or more places.

[0047] The integral hinge 23 is provided on the outside of a U-shape formed by one side portion 21a and the stopper portion 21b of the base portion 21 and the other side portion 22a of the movable portion 22 when in the use position 22-2.

[0048] In the first embodiment of the present invention, in addition to the above-mentioned actions and effects (A)-(F) common to all the embodiments of the present invention, the following actions and effects can be obtained.

[0049] (G1) The base portion 21 has the stopper portion 21b which abuts against the movable portion 22 when the movable portion 22 is in the use position 22-2 and prevents the movable portion 22 from rotating beyond the use position 22-2 when the movable portion 22 is rotated around the integral hinge 23 from the molding position 22-1 to the use position 22-2. Therefore, when the movable portion 22 is rotated around the integral hinge 23 from the molding position 22-1 to the use position 22-2, the movable portion 22 can be prevented from rotating beyond the use position 22-2.

[0050] (G2) Since the stopper portion 21b extends from one side portion 21a of the base 21 toward the other side portion 22a of the movable part 22 when it is in the use position 22-2, when the movable part 22 is rotated around the integral hinge 23 from the molding position 22-1 to the use position 22-2, the movable part 22 can be abutted against the stopper portion 21b, and the stopper portion 21b can prevent the movable part 22 from rotating beyond the use position 22-2.

[0051] (G3) One side portion 21a and the stopper portion 21b of the base portion 21 and the other side portion 22a of the movable portion 22 when in the usage position 22-2 form a U-shape in a cross-sectional view perpendicular to the rail longitudinal direction L to accommodate the slide protrusion 30 in the inner space S. Therefore, the base portion 21 and the movable portion 22 can support the slide protrusion 30 so that it can slide in the rail longitudinal direction L, and can prevent the slide protrusion 30 from coming off the guide rail 20 in a direction perpendicular to the rail longitudinal direction L.

[0052] (G4) When the movable part 22 is in the use position 22-2, the movable part 22 abuts against both the outer surface 21b1 and the extension direction end surface 21b2 of the stopper part 21b. Therefore, unlike the case where the movable part 22 is in contact only with the outer surface 21b1 of the stopper part 21b and is not in contact with the extension direction end surface 21b2 of the stopper part 21b, even when the movable part 22 is connected to the base part 21 by the integral hinge 23, the distance between one side part 21a of the base part 21 and the other side part 22a of the movable part 22 in the use position 22-2 can be a predetermined distance D1.

[0053] (G5) A claw portion 24 is provided on one of the base portion 21 and the movable portion 22, and a claw receiving portion 25 is provided on the other of the base portion 21 and the movable portion 22 with which the claw portion 24 engages when the movable portion 22 is in the use position 22-2, thereby preventing the movable portion 22 in the use position 22-2 from rotating around the integral hinge 23 toward the molding position 22-1. Therefore, by engaging the claw portion 24 with the claw receiving portion 25, it is possible to prevent the movable part 22 in the use position 22-2 from rotating around the integral hinge 23 toward the molding position 22-1.

[0054] (G6) The stopper portion 21b, the claw portion 24, and the claw receiving portion 25 can hold the movable portion 22, which has been rotated around the integral hinge 23 from the molding position 22-1 to the use position 22-2, at the use position 22-2 relative to the base portion 21. Therefore, when the slide protrusion 30 slides along the guide rail 20 or when an external force including an impact load is applied to the slide rail structure 10, it is possible to prevent the movable portion 22 from shifting from the use position 22-2 relative to the base portion 21. In addition, an extension portion 22b is provided that extends from the other side portion 22a of the movable portion 22 toward a vehicle interior member (not shown) to which the device 100 is attached, and the extension portion 22b is brought into contact with the vehicle interior member when the device 100 is attached to the vehicle interior member, thereby making it possible to hold the movable portion 22 with the vehicle interior member. In this case, it is possible to effectively prevent the movable portion 22 from shifting from the use position 22-2 relative to the base portion 21.

[0055] [Example 2] (Figs. 9 and 10) The second embodiment of the present invention is as follows. The movable part 22 includes an other-side portion facing part 22d located opposite the other-side portion 22a, and a connecting part 22e connecting the other-side portion 22a and the other-side portion facing part 22d. In a cross-sectional view perpendicular to the rail longitudinal direction L, the other-side portion 22a, the other-side portion facing part 22d, and the connecting part 22e are U-shaped to receive the slide protrusion 30 in the inner space S1 when the movable part 22 is in the use position 22-2.

[0056] That is, in embodiment 1 of the present invention, one side portion 21a and the stopper portion 21b of the base portion 21 and the other side portion 22a of the movable portion 22 when in the use position 22-2 form a U-shape in a cross section perpendicular to the rail longitudinal direction L to accommodate the slide protrusion 30 in the inner space S, whereas in embodiment 2 of the present invention, only the movable portion 22 forms a U-shape in a cross section perpendicular to the rail longitudinal direction L to accommodate the slide protrusion 30 in the inner space S1.

[0057] The other side facing portion 22d of the movable portion 22 abuts against the one side portion 21a of the base portion 21 when the movable portion 22 is in the use position 22-2.

[0058] The integral hinge 23 is provided on the outside of a U-shape formed by the other side portion 22a of the movable portion 22, the other side portion opposing portion 22d, and the connecting portion 22e.

[0059] In the second embodiment of the present invention, in addition to the above-mentioned actions and effects (A)-(F) common to all the embodiments of the present invention, the following actions and effects can be obtained.

[0060] (H1) The other side portion 22a, the other side opposing portion 22d and the connecting portion 22e of the movable portion 22 have a U-shape in a cross section perpendicular to the rail longitudinal direction L to receive the slide protrusion 30 when the movable portion 22 is in the inner space S1 in the usage position 22-2. Therefore, the other side portion 22a, the other side opposing portion 22d and the connecting portion 22e of the movable portion 22 can support the slide protrusion 30 so as to be slidable in the rail longitudinal direction L, and can prevent the slide protrusion 30 from coming off the guide rail 20 in a direction perpendicular to the rail longitudinal direction L.

[0061] (H2) Since the other side opposing portion 22d of the movable part 22 abuts against one side portion 21a of the base part 21 when the movable part 22 is in the use position 22-2, when the movable part 22 is rotated around the integral hinge 23 from the molding position 22-1 to the use position 22-2, the movable part 22 can be prevented from rotating beyond the use position 22-2.
