Description

  The present invention relates to a shutter that is slidably disposed along a pair of guide rails arranged to face each other.

  In a floor console installed in a passenger compartment of an automobile, an article storage portion opened upward is defined in the console body. As a lid member that opens and closes the upper opening of the article storage section, a lid member that employs a sliding shutter 80 is known (see, for example, Patent Document 1). The shutter 80 is engaged with a pair of guide rails L <b> 1 and L <b> 2 that are disposed facing the left and right sides of the article storage portion by engaging a shaft portion 90 provided at each end of the shutter 80. A longitudinal slide is possible along the guide rails L1 and L2.

  The shutter 80 extends substantially horizontally and flatly on the upper surface of the console body when the upper opening of the article storage portion is covered. Further, in a state where the upper opening is opened, the console body is stored in a curved state inside the rear side. In addition, in the state where the upper opening is covered, the shutter 80 may be subjected to a load from the front side (upper side) such as placing an article or an arm (elbow) on the upper surface or putting a hand on getting on and off the passenger compartment. For this reason, the shutter 80 needs to have both flexibility that can be deformed into a flat state and a curved state, and rigidity that supports a certain load. Therefore, as shown in FIGS. 7 and 8, the shutter 80 includes a plate member 82 formed of a soft resin (such as a thermoplastic elastomer) and a hard resin (polyethylene, polypropylene, ABS, polycarbonate, etc.) harder than the soft resin. ).

  In the plate member 82, cell portions 84 and hinge portions 86 thinner than the cell portions 84 are alternately formed in the sliding direction, and each cell portion 84 and each hinge portion 86 can be bent and deformed. A plurality of bearing members 88 are fixed to each cell portion 84 so as to be separated from each other in the sliding direction, and one shaft portion 90 projects from each end portion. Thus, in the shutter 80, the bearing members 88 are individually separated from each other in the sliding direction and arranged in the cell portion 84, and not only the hinge portion 86 but also the cell portion 84 is allowed to bend and deform.

JP 2008-24099 A

  By the way, in the shutter 80 described above, as shown in FIG. 8, each of the bearing members 88 is supported by the shaft portions 90 formed one at each end being hooked on the corresponding guide rails L <b> 1 and L <b> 2. ing. That is, each bearing member 88 is supported by the guide rails L1 and L2 in the form of two-point support by both shaft portions 90 and 90, as shown in FIG. Further, the shaft portion 90 has an arcuate surface facing the guide rail L1, and the contact point P with respect to the guide rails L1 and L2 is a point contact. For this reason, when a load is applied from the front side of the shutter 80, each bearing member 88 may be rotationally displaced about the line B1 passing through the center of each shaft portion 90 in the width direction. As shown in FIG. 8B, when a load is applied to the hinge portion 86 from the front side, the two bearing members 88, 88 adjacent to each other with the hinge portion 86 interposed therebetween are opposite to each other about the line B1. Rotating displacement in the direction. Further, as shown in FIG. 8B, when a load is applied to the cell portion 84 from the front side, the two bearing members 88 and 88 disposed adjacent to the cell portion 84 are arranged with the line B1 as an axis. It becomes rotationally displaced in directions opposite to each other. For this reason, stress concentrates between the adjacent bearing members 88, 88 in the hinge part 86 and the cell part 84, and the hinge part 86 or the cell part 84 may be broken. Further, if a load is applied from the front side of the shutter 80 in a state where the bearing member 88 is overturned, the bearing member 88 does not exhibit the designed rigidity, and the bearing member 88 itself may be damaged.

  An object of the present invention is to provide a shutter that prevents damage due to application of a load.

According to the first aspect of the present invention, when the load is applied to the shutter, each of the support portions is a pair of a total of four abutting portions that are formed in each of the end portions in a sliding direction. Therefore, the support portion is prevented from being rotationally displaced about an axis extending in the width direction orthogonal to the sliding direction due to a load from the front side of the shutter. As described above, when a load is applied to each support member from the front side of the shutter, the stress is not easily concentrated on the hinge portion connecting the support member portions, and therefore, the shutter can be made of a material more flexible than each support member portion. A flexible hinge portion can be formed. In particular, since each support portion becomes a rib structure with a pair of beam portions and a connecting portion that connects both beam portions, it is possible to obtain rigidity that hardly causes bending deformation and torsional deformation even under an assumed load. it can.

The contact portions adjacent to each other with the hinge portion interposed therebetween are formed so that the surfaces facing each other are separated from each other in the sliding direction as the distance from the hinge portion in the flat state of the shutter. Even if the distance between the contact portions in the sliding direction is set large, the shutter does not come into contact with the curved state, and the shutter is not restricted from being deformed into the curved state. Moreover, since the space | interval in the sliding direction of a pair of contact part provided in the support body part can be enlarged, the stability of a support body part when a load is added in the flat state of a shutter can be improved.

According to a fourth aspect of the present invention, each support member has a thickness dimension that is perpendicular to the sliding direction and is minimized at both ends in the facing direction of the pair of guide rails, and a central portion in the facing direction. Is formed larger than both ends.
According to the fourth aspect of the present invention, even when a load is applied to the support portion, the support portion is difficult to bend and deform in the thickness direction perpendicular to the sliding direction, and stress is concentrated on the hinge portion. Is prevented.

The gist of the invention described in claim 5 is that each of the abutting portions is configured such that a surface abutting on the guide rail is formed in a curved surface and is in point contact with the guide rail.

Thus, the support body portion 10 protrudes toward the back side where the beam portions 14 and 16 intersect with the covering 28 and a space is defined between the first beam portion 14 and the second beam portion 16. It is configured as a so-called ladder-like rib structure.

  As shown in FIG. 5, the first beam portion 14 and the second beam portion 16 are formed in a symmetric shape with respect to the center in the length direction of the plate portion 12. As shown in FIG. 5, each beam part 14, 16 has a maximum width (G) on the hinge part 30 side (side connected to the plate part 12) (G 1). The distance gradually decreases as the distance increases, and is the minimum (G2) at the extended end opposite to the plate portion 12. The first beam portion 14 and the second beam portion 16 are obliquely formed so that the outer surfaces facing the adjacent support body portion 10 are closer to each other as the distance from the hinge portion 30 side increases. , 10 are widened so as to spread toward the back side. In addition, each of the beam portions 14 and 16 is formed so that the dimension in the thickness direction is larger in the central portion than in the end portion (see FIG. 3). Each of the beam portions 14 and 16 of the embodiment has a maximum dimension (H1) in the thickness direction over a predetermined range in the center in the width direction, and a minimum dimension (H2) in the thickness direction at both ends. And each beam part 14 and 16 is formed in the inclined shape so that the thickness range may become small gradually as the predetermined range toward the width direction center from both ends approaches each end part from the center part side. . In addition, the dimension of the thickness direction of each beam part 14 and 16 is set largely with respect to the dimension of a length direction. The support body portion 10 configured in this way has a rigidity equivalent to that of a block shape in which the space between both beam portions 14 and 16 is filled with a hard resin, and even if a load is applied from the front side, both beam portions 14 and 16 are secured. Are difficult to deform in the direction in which they come in contact with and away from each other, and bending deformation and torsion deformation in the width direction are difficult to develop.

  As shown in FIG. 5, the support body 10 has a maximum dimension (W1) in the length direction on the hinge part 30 side (plate part 12). Moreover, the dimension of the support body part 10 in the longitudinal direction gradually decreases as the distance from the hinge part 30 increases, and the end part on the opposite side of the hinge part 30 is minimum (W2). That is, the support body portion 10 has a substantially trapezoidal shape in which the shape seen from the outside in the width direction of the shutter S is tapered as the distance from the hinge portion 30 increases.

  As shown in FIGS. 1 to 5, the sliding support portions 20 are provided at one end and the other end in the width direction of each support 10. The paired sliding support portions 20, 20 provided at both ends of the support body portion 10 are formed in a symmetrical shape with the center in the width direction of the support body portion 10 interposed therebetween. The sliding support part 20 is provided on the back side of the part connected to the hinge part 30 in the support body part 10. The sliding support portion 20 includes a first contact portion 22 provided at the end portion of the first beam portion 14 and a second contact portion 24 provided at the end portion of the second beam portion 16. . In the sliding support portion 20 of the embodiment, the first contact portion 22 and the second contact portion 24 are provided to be separated from each other in the length direction, and the first contact portion 22 and the second contact portion 24 are Are independent (see FIG. 1). Here, each support member 10 is provided with a pair of abutting portions 22 and 24 in a symmetrical relationship at each end with a center in the length direction of the support member 10 interposed therebetween. Each contact part 22, 24 is formed at an arm part 25 formed so as to extend outward in the width direction from the end part of the corresponding beam part 14, 16, and at an extension end of this arm part 25. And a sliding contact portion 26 (see FIG. 3). The arm portion 25 has a substantially rectangular longitudinal cross-sectional shape, and is formed with a large size in the thickness direction at the connection portion with the corresponding beam portions 14 and 16, so that deformation in the length direction and the thickness direction is difficult to occur.

  As shown in FIGS. 4 and 5, the sliding contact portion 26 is formed in a substantially circular shape centered on a center line J extending in the length direction when viewed from the length direction. That is, the front end surface 26a of the sliding contact portion 26 is formed in an arc shape that protrudes outward, and the front end surface 26a is in contact with the side wall surface 114A of the groove portion 114 in the guide rails L1 and L2. Configured for point contact. Further, the sliding contact portion 26 is formed in an arc shape in which an end face (referred to as a back end face) 26b facing the back side in the thickness direction is convex toward the back side in the thickness direction, and an end face (referred to as the front end face) facing the thickness direction front side. 26c is formed in the circular arc shape which becomes convex toward the thickness direction front side. Thus, the back end surface 26b of the sliding contact portion 26 is configured to be in point contact when contacting the back wall surface 114B of the groove portion 114 in the guide rails L1 and L2. Further, the front end surface 26c of the sliding contact portion 26 is configured to be in point contact when contacting the front wall surface 114C of the groove portion 114 in the guide rails L1 and L2. The sliding contact portion 26 is set such that the dimension in the thickness direction between the apex of the back end surface 26b and the apex of the front end surface 26c is the same as or slightly smaller than the interval between the back wall surface 114B of the groove 114 and the front wall surface 114C. The sliding contact portion 26 is caught between the back wall surface 114B and the front wall surface 114C of the groove portion 114 by the side surfaces 114B and 114C of the groove portion 114 where at least one of the back end surface 26b and the front end surface 26c faces each other, and displacement in the thickness direction is restricted. Is done. Further, the sliding contact portion 26 is restricted from being displaced in the width direction by the front end surface 26 a contacting the side wall surface 114 </ b> A of the groove portion 114.

  As shown in FIG. 5, the sliding contact portion 26 is directed from the hinge portion 30 side to the side away from the hinge portion 30 in accordance with the trapezoidal shape of the support body portion 10 on which the sliding contact portion 26 is formed. It is formed in a tapered shape. That is, the sliding contact portion 26 of the first contact portion 22 is inclined so that the portion away from the hinge portion 30 on the side surface opposite to the second contact portion 24 matches the inclined outer wall of the first beam portion 14. Formed. Similarly, the sliding contact portion 26 of the second contact portion 24 is inclined in accordance with the inclined outer wall of the second beam portion 16 at a portion away from the hinge portion 30 on the side surface opposite to the first contact portion 22. It is formed in a shape. As a result, the first contact portion 22 of the sliding support portion 20 formed on one of the adjacent support portions 10 and the second contact portion 24 of the slide support portion 20 formed on the other support portion 10. Is larger on the side farther from the hinge part 30 than on the hinge part 30 side when the shutter S is flat. Therefore, when the posture is displaced so that the adjacent support body portions 10 and 10 are close to each other due to elastic deformation of the hinge portion 30, the first contact portion 22 and the second contact portion of the adjacent slide support portions 20 and 20 are moved. Contact with the portion 24 is prevented.

  The shutter S inserts the first contact portion 22 and the second contact portion 24 of the sliding support portion 20 provided at one end portion of each support body portion 10 into the groove portion 114 of one guide rail L1, The first contact portion 22 and the second contact portion 24 of the sliding support portion 20 provided at the other end portion of each support body portion 10 are inserted into the groove portion 114 of the other guide rail L2. As a result, the shutter S is slidably disposed with respect to the console body 100. As shown in FIGS. 3, 4, and 5, each of the support body portions 10 includes a first contact portion 22 and a second contact portion 24 of one slide support portion 20, and the other slide. Of the total four contact portions 22, 24 including the first contact portion 22 and the second contact portion 24 of the support portion 20, at least three contact portions 22, 24 are supported by the guide rails L1, L2. It is configured to receive a load from the front side in the state. At one end portion of each support body portion 10, contact points P and P at which the pair of contact portions 22 and 24 in one sliding support portion 20 contact the groove portion 114 of one guide rail L1 are in the length direction. Two are provided apart from each other. Further, at the other end portion of each support body portion 10, contact points P and P at which the pair of contact portions 22 and 24 in the other sliding support portion 20 contact the groove portion 114 of the other guide rail L2 are provided. Two are provided apart in the length direction. Each support member 10 is supported by being hooked on the groove 114 at a contact point P in which the lines B connected to each other are arranged in a quadrangular or triangular relationship in plan view.

  As shown in FIGS. 2 and 5, the covering body 28 having the hinge portion 30 is a plate-like body that is separate from the support portion 10 and is made of a flexible foam such as urethane having flexibility. ing. For example, the shutter S is formed by injecting a foam material into a mold in which the support body portion 10 on which the sliding support portion 20 is formed is set, and foaming and molding the soft foam forming the covering body 28. It is formed by joining the covering 28. Note that the shutter S may be formed by bonding the support 10 and the cover 28 formed separately with an adhesive or the like. As shown in FIG. 5, the support body portion 10 is disposed so as to embed the plate portion 12 on the back side of the cover body 28, and ensures a large bonding area between the support body portion 10 and the cover body 28. In the case where the covering 28 is formed of a soft urethane resin foam, the adhesiveness between the covering 28 and the support 10 is improved when the support 10 is formed of ABS or PC or an alloy thereof. This is preferable.

  As shown in FIGS. 1 to 3, the covering body 28 connects the support portions 10 and 10 adjacent to each other in the length direction by a hinge portion 30, and connects a plurality of support portions 10 side by side. Yes. The hinge portion 30 can be elastically bent or bent so that the entire shutter S is concave or convex in the thickness direction. In addition, the adjacent support body parts 10 and 10 adjoin each other, and the hinge part 30 has the 1st beam part 14 of one adjacent support body part 10, and the 2nd beam part 16 of the other support body part 10. Deformation is allowed until contact.

  In the shutter S of the embodiment, the plate portion 12 of the support body portion 10 on the front side of the floor console FC extends in the width direction with substantially the same dimension as the length direction of the support body portion 10 and protrudes upward. A grip portion 32 is provided. Therefore, the sliding operation of the shutter S can be easily performed by holding the holding part 32 with the fingertip.

  In the shutter S, at the position facing the upper opening 104 of the article storage portion 102, the sliding support portions 20, 20 of the support body portion 10 are positioned on the straight portions 110 of the guide rails L 1, L 2, and a single flat plate is formed. Thus, the upper opening 104 is entirely covered (see FIG. 4). When the shutter S receives a load in the thickness direction from the front side, the back end surfaces 26b and 26b of at least three of the four contact portions 22 and 24 out of the four contact portions 22 and 24 become the back wall surface 114B of the groove portion 114. The load applied to each support body 10 is dispersed and supported by these contact portions 22 and 24. Even if a force is applied in the direction of rotational displacement about the axis connecting the contact points P and P of the contact portions 22 and 22 (24 and 24) formed symmetrically across the beam portion 14 (16). Since the abutting portions 24 (22) forming a pair spaced apart in the length direction are caught by the groove portions 114, the rotational displacement of the support body portion 10 is restricted. In particular, the first contact portion 22 and the second contact portion 24 sandwiching the hinge portion 30 even when concentrated on the hinge portions 30 of the adjacent support portions 10 and 10 and receiving a load in the thickness direction from the front side of the shutter S. Is caught on the back wall surface 114B of the groove portion 114, and the second contact portion 24 and the first contact portion 22 forming a pair in each support body portion 10 are hooked on the front wall surface 114C of the groove portion 114. Thereby, rotation displacement of the support body parts 10 and 10 adjacent on both sides of the hinge part 30 is controlled. Even when a load is concentrated in the thickness direction from the front side between the beam portions 14 and 16 of each support body portion 10, the support body portion 10 is configured as a rigid body. Even if 16 spaces are covered with the flexible covering 28, it is possible to prevent bending. As described above, each support body portion 10 that receives a load in the thickness direction from the front side includes the first contact portion 22 and the second contact portion 24 of one slide support portion 20, and the other slide support portion 20. Since at least three of the first abutment portion 22 and the second abutment portion 24 come into contact with the groove portions 114 in the guide rails L1 and L2, the axis extending in the width direction. The posture is stably maintained without rotational displacement around the center. Each support member 10 has a rib structure including the first beam portion 14, the second beam portion 16, and the connecting portion 18 and has rigidity. Therefore, even if a load is applied from above the plate portion 12. The bending deformation and the twist deformation in the width direction can be reduced. Therefore, the shutter S is flat even when a certain load is applied from above, such as placing an article or an occupant's arm on the front side facing upward, or putting a hand on the front side in a flat state where the upper opening 104 is covered. State is maintained properly.

  Moreover, since the first contact portion 22 and the second contact portion 24 of the sliding support portion 20 are provided at one end portion and the other end portion across the center in the length direction of the support body portion 10, Even when a load is applied from the front side to a position shifted from the center in the length direction with respect to the support body part 10 (position closer to the hinge part 30 than the center), the support body part 10 is centered on the axis extending in the width direction. Rotational displacement is unlikely to occur.

  When the shutter S slides toward the rear of the console main body 100 from the state in which the upper opening 104 is covered, the shutter S moves from the rear support portion 10 in the length direction to the curved portions 112 of the guide rails L1 and L2. become. When the support body part 10 moves to the curved part 112 of each guide rail L1, L2, the front end surface 26c of the first contact part 22 in each sliding support part 20 provided in the support body part 10 and the second contact part The front end surface 26c of the portion 24 comes into contact with the front wall surface 114C of the groove portion 114 of each guide rail L1, L2. As a result, the support portions 10 and 10 that have moved to the curved portions 112 of the guide rails L1 and L2 are supported on one side by the elastic deformation of the hinge portion 30 between the support portions 10 and 10. The other support body 10 is displaced with respect to the body 10. As shown in FIG. 1B, the shutter S is deformed into a curved state along the curved portions 112 of the guide rails L1 and L2 as the hinge portions 30 are elastically deformed.

  In this way, when the load is applied to each support body portion 10 from the front side, the shutter S does not easily concentrate stress on the hinge portion 30 that connects the support body portions 10. It can be formed of a soft foam or the like that is a softer material than the sliding support portion 20. Further, since the stress is unlikely to concentrate at a specific location in the shutter S, even if the support body portion 10 and the covering body 28 are joined, the both 10 and 28 are difficult to peel off. And by forming the hinge part 30 with a flexible material, the shutter S can be slid with a light force, and the operability when the shutter S is opened and closed can be improved. Further, since the contact portions 22 and 24 are configured to make point contact with the groove portion 114, the frictional resistance with the groove portion 114 can be kept small, and the shutter S can be slid and moved with a light force. The operability when opening and closing the shutter S is improved. Moreover, the cover 28 not only bends the hinge part 30 positioned between the adjacent support parts 10 and 10 but also expands and contracts the area covering the front side of the support part 10, thereby further improving the operability of the shutter S. it can. Further, the shutter S is composed of a cover 28 made of a soft soft foam, so that the touch when touched is good and can be used as an armrest or the like.

  The lower portions of the surfaces facing each other across the hinge portion 30 of the adjacent sliding contact portions 26 and 26 are formed so as to be separated from each other in the length direction as the distance from the hinge portion 30 increases in the flat state of the shutter S. Therefore, the first contact portion 22 and the second contact portion 24 in the sliding support portion 20 do not come into contact when the shutter S is deformed into a curved state even if the interval in the length direction is set large. The deformation of the shutter S into the curved state is not restricted. And since the space | interval in the length direction of the 1st contact part 22 and the 2nd contact part 24 in the sliding support part 20 can be enlarged, even when a load is added in the flat state of the shutter S, the support part 10 Can improve the stability.

  Further, it is assumed that each support body portion 10 becomes a rib structure by the first beam portion 14 and the second beam portion 16 arranged in the length direction and the connecting portion 18 that connects both the beam portions 14 and 16. Even when subjected to a load, it is possible to obtain rigidity that hardly causes bending deformation and torsional deformation. In particular, since the first beam portion 14 and the second beam portion 16 of each support body portion 10 are set to have a large height in the central portion in the width direction, the load applied to the shutter S from the front side is subjected to bending deformation. I can receive it properly. In addition, since each support body portion 10 is formed in a trapezoidal shape in which the dimension in the length direction becomes tapered as the distance from the hinge portion 30 in the thickness direction is increased, the curved state of the shutter S due to the deformation of the hinge portion 30. Deformation to is not regulated.
