<First Embodiment>
Hereinafter, the attachment structure with respect to the shaft of the sheet-like member which concerns on 1st Embodiment is demonstrated. Here, the attachment structure with respect to the winding shaft 30 of the sheet-like member 20 in the sheet winding apparatus 10 will be described as an example (see FIGS. 1 and 2). The sheet winding device 10 is a device that winds the sheet-like member 20 around the winding shaft 30 so as to be retractable. FIG. 1 illustrates a tonneau cover device that covers the upper part of a cargo compartment of an automobile (separates the boarding space and the cargo compartment) as the sheet winding device 10. In addition, the sheet winding device is not limited to the tonneau cover device but may be used as a shade device for shielding a window of an automobile.

<Sheet take-up device>
First, an outline of the sheet winding device 10 will be described. The sheet winding device 10 includes a sheet-like member 20, a winding shaft 30, a support portion 40, and a coil spring 50 (see FIG. 2).

  The sheet-like member 20 is a member formed by cutting, sewing or the like of a cloth material, a mesh-like cloth material, a resin sheet or the like. The sheet-like member 20 is formed in a shape and size according to the application. Here, it is formed in a shape and size that can cover the upper part of the cargo compartment. In FIG. 2, a wide portion, a portion gradually narrowing from the wide portion, and a narrow portion narrower than the wide portion are formed in a continuous shape. In addition, a drawing member 70 for drawing operation may be provided at the edge of the sheet-like member 20 on the narrow portion side.

  The winding shaft 30 is formed in a rod shape and is a portion around which the sheet-like member 20 is wound. Here, the winding shaft 30 is formed in a long cylindrical shape. A sheet-like member 20 (an end portion on the wide portion side) is attached to the winding shaft 30. Further, end members 32 are fitted to both ends of the winding shaft 30 so as not to rotate around the central axis. The end member 32 has a cylindrical inner peripheral surface on the inner side.

  The winding shaft 30 is supported by the support portion 40 so as to be rotatable around the central axis. The support portion 40 includes a casing main body portion 42 and a pair of side covers 44. The casing main body 42 is formed in a long cylindrical shape that can accommodate the winding shaft 30 around which the sheet-like member 20 is wound. Further, a slit that allows the sheet-like member 20 drawn from the winding shaft 30 to pass through is formed in the casing main body 42 along the longitudinal direction. The pair of side covers 44 are attached to both ends of the casing main body 42 in a form that closes the openings at both ends. Each of the pair of side covers 44 includes a rotation support portion 46 that supports the winding shaft 30 so as to be rotatable around the central axis. The rotation support portion 46 has a cylindrical protrusion, and the protrusions are fitted to the end members 32 at both ends of the winding shaft 30 so as to be relatively rotatable around the center axis. .

  The coil spring 50 urges the winding shaft 30 to rotate in the direction in which the sheet-like member 20 is wound around the support portion 40. The coil spring 50 is disposed on the inner peripheral side of the winding shaft 30 along the central axis direction of the winding shaft 30, and one end is fixed to one rotation support portion 46 and the other end is wound. The shaft 30 is fixed to the inner peripheral portion.

<Attachment structure of sheet-like member to winding shaft>
The sheet-like member 20 is formed with a plurality of insertion holes 22 through which the take-up shaft 30 can be inserted at positions aligned in one direction (see FIG. 2). Here, the one direction is a direction along the edge portion on the storage side, and may hereinafter be referred to as the width direction of the sheet-like member 20. And the sheet-like member 20 is attached with respect to the winding shaft 30 by the winding shaft 30 being inserted in each of the plurality of insertion holes 22 of the sheet-like member 20 (see FIG. 3). That is, the winding shaft 30 is inserted into the plurality of insertion holes 22 so as to sew the sheet-like member 20, and is exposed alternately on one side and the other side of the sheet-like member 20.

  The insertion hole 22 is formed in a circular hole shape (see FIG. 2). More specifically, the insertion hole 22 is set to have a diameter that is larger (slightly larger here) than that of the winding shaft 30. However, the insertion hole 22 may be formed in an elliptical hole shape.

  Further, an even number of insertion holes 22 are formed. More specifically, a plurality of pairs of insertion holes 22 are formed such that both ends of the winding shaft 30 are exposed on the same surface side of the sheet-like member 20. Further, the plurality of pairs of insertion hole portions 22 are formed at equal intervals for each pair. Note that FIG. 2 shows an example in which three pairs (six) of insertion holes 22 are formed. The three pairs of insertion hole portions 22 are formed at both end portions and the center position in the width direction of the sheet-like member 20.

  However, the number of the plurality of insertion hole portions 22 is not limited to three pairs, but relates to the strength of the sheet-like member 20 itself and the inner peripheral edge portion of the insertion hole portion 22 when an external force acts on the sheet-like member 20. It may be set in consideration of the load and insertion workability of the winding shaft 30 with respect to the plurality of insertion holes 22. Furthermore, an odd number of the plurality of insertion holes 22 may be formed.

  In the sheet-like member 20, each side portion of the plurality of insertion holes 22 in one direction in which the plurality of insertion holes 22 are arranged extends along the outer peripheral surface of the winding shaft 30. More specifically, each side portion of the plurality of insertion hole portions 22 has a semicircular arc-shaped outer circumferential surface (alternately on one side and the other side of the winding shaft 30 in the thickness direction of the sheet-like member 20). At least the middle part of each semicircular arc). That is, each side portion of the plurality of insertion hole portions 22 of the sheet-like member 20 extends linearly along the longitudinal direction of the winding shaft 30 in one direction in which the plurality of insertion hole portions 22 are arranged. Yes. In other words, each side part of the plurality of insertion holes 22 is not curved or bent in the longitudinal direction of the winding shaft 30.

  Further, in the sheet-like member 20, a part of one side portion of the plurality of insertion hole portions 22 in a direction (drawing and storing direction) orthogonal to one direction (width direction) in which the plurality of insertion hole portions 22 are arranged is wound up. The shaft 30 is bonded to the outer peripheral surface. That is, the portion of the sheet-like member 20 on the storage side from the plurality of insertion holes 22 is bonded by the adhesive so as to follow the outer peripheral surface of the winding shaft 30 (see FIG. 5). For convenience of explanation, in the following, in the sheet-like member 20, a portion on the storage side from the plurality of insertion holes 22 is referred to as a first portion 201, and a portion on the extraction side from the plurality of insertion holes 22 is referred to as a second portion 202. Yes (see FIG. 2).

  Here, the double-sided pressure-sensitive adhesive tape 24 is adopted as the adhesive. More specifically, a double-sided pressure-sensitive adhesive tape 24 is attached to one surface of the first portion 201 of the sheet-like member 20 along the width direction (see FIG. 4). And the 1st part 201 with which the double-sided adhesive tape 24 was affixed among the sheet-like members 20 was folded in the form along the outer peripheral surface of the winding shaft 30, and on the outer peripheral surface and outer peripheral surface of the winding shaft 30 It is affixed with respect to the extending sheet-like member 20 (refer FIG. 6, FIG. 7).

  Preferably, the sheet-like member 20 is bonded to the outer peripheral surface of the take-up shaft 30 on the side where the take-up shaft 30 is exposed at both ends in one direction in which the plurality of insertion hole portions 22 are arranged ( (See FIG. 5). That is, the first portion 201 of the sheet-like member 20 is preferably bonded to the outer peripheral surface of the winding shaft 30 at both ends in the width direction. More preferably, the sheet-like member 20 is on the side of the winding shaft 30 that is exposed on the one surface side and the other surface side of the sheet-like member 20 alternately, and on the side having a large exposure range in the longitudinal direction. It is good to adhere | attach on the outer peripheral surface of 30 (refer FIG. 3). That is, the first portion 201 of the sheet-like member 20 may be bonded to the outer peripheral surface of the winding shaft 30 in a wider range. FIG. 3 shows an example in which both of the above two more preferable conditions are satisfied.

  Although it is preferable to satisfy both of the above two conditions, the sheet-like member 20 is attached to the take-up shaft 30 regardless of whether an adhesive form that satisfies only one of the above conditions is employed or an adhesive form that does not satisfy either of the above conditions. Thus, it can be fixed so as not to rotate around the central axis. FIG. 9 shows an example in which the sheet-like member 20 is bonded to the outer peripheral surface of the take-up shaft 30 on the side where both ends in the longitudinal direction of the take-up shaft 30 are not exposed.

<Effect>
According to the structure for attaching the sheet-like member 20 to the take-up shaft 30 according to the embodiment, the sheet-like member 20 is attached to the take-up shaft 30 in a form in which the take-up shaft 30 is inserted into the plurality of insertion holes 22. It has been. For this reason, even if a tensile force acts on the sheet-like member 20, the load is distributed to the tensile-side portion and the opposite-side portion of the inner peripheral edge portion of the insertion hole portion 22 and is applied to the sheet-like member 20. The load can be reduced as much as possible.

  For example, as shown by a two-dot chain line in FIG. 8, when the sheet-like member 22 is pulled toward the drawing side with respect to the winding shaft 30, the drawing side portion and the storage side portion of the inner peripheral edge portion of the insertion hole portion 22 Receive the load in a distributed manner. More specifically, the tensile load is a take-up shaft 30 that extends on one side or the other side of the sheet-like member 20 at the drawer side portion and the storage side portion of the inner peripheral edge of the insertion hole portion 22. Are distributed in the direction along the outer peripheral surface of each.

  In addition, since each side portion of the plurality of insertion hole portions 22 in one direction in which the plurality of insertion hole portions 22 are arranged in the sheet-like member 20 extends along the outer peripheral surface of the winding shaft 30, The entire sheet-like member 20 can be prevented from being bent or slack. In the sheet winding device 10, the sheet-like member 20 is stretched as a whole and extends in a planar shape when the sheet-like member 20 is pulled out.

  Moreover, since the winding shaft 30 is formed in a cylindrical shape, contact of the edge-shaped portion with the inner peripheral edge portion of the insertion hole portion 22 of the sheet-like member 20 can be suppressed. And the inner peripheral edge part of the insertion hole part 22 of the sheet-like member 20 contacts the wide curved outer peripheral surface of the winding shaft 30, and the load concerning the sheet-like member 20 can be disperse | distributed widely. Thereby, the tear etc. from the insertion hole part 22 of the sheet-like member 20 can be suppressed, and the drop-off | omission from the winding shaft 30 of the sheet-like member 20 can be suppressed.

  Moreover, since the whole winding shaft 30 is penetrated with respect to the some penetration hole part 22, formation of a notch etc. can be avoided and the intensity | strength of the winding shaft 30 can be maintained. Moreover, since the process of the winding shaft 30 can be reduced, it contributes to reduction of the cost and man-hour concerning this.

  Further, the sheet-like member 20 can be easily attached to the take-up shaft 30 by sequentially passing the take-up shaft 30 through the plurality of insertion holes 22 so as to sew the sheet-like member 20.

  Further, since the insertion hole portion 22 is formed in a circular hole shape, even if a tensile force acts on the sheet-like member 20, the load is easily dispersed, and the load applied to the inner peripheral edge portion of the insertion hole portion 22 is reduced. It can be made smaller.

  Further, since the even number of the insertion holes 22 are formed, the sheet-like member 20 can be attached to the winding shaft 30 in a stable form.

  Further, since the sheet-like member 20 is fixed so as not to be relatively movable in the central axis direction of the take-up shaft 30 with respect to the take-up shaft 30, the relative movement of the sheet-like member 20 in the central axis direction with respect to the take-up shaft 30 is prevented. Can be suppressed.

  Further, since the sheet-like member 20 is fixed to the take-up shaft 30 so as not to be relatively rotatable around the central axis of the take-up shaft 30, the sheet-like member 20 is relatively rotated around the central axis with respect to the take-up shaft 30. Can be suppressed.

  Further, in the sheet-like member 20, a portion (first portion 201) on one side of the plurality of insertion hole portions 22 in a direction (winding direction) orthogonal to one direction (width direction) in which the plurality of insertion hole portions 22 are arranged. Is bonded to the outer peripheral surface of the winding shaft 30. For this reason, the sheet-like member 20 can be fixed to the winding shaft 30 so that it cannot rotate around the central axis and cannot move in the central axis direction. Further, the tensile strength is improved at the bonded portion.

  Further, the sheet-like member 20 is bonded to the outer peripheral surface of the winding shaft 30 on the side where the winding shaft 30 is exposed at both ends in one direction in which the plurality of insertion hole portions 22 are arranged. For this reason, both ends of the sheet-like member 20 can be fixed to the take-up shaft 30 in the longitudinal direction of the take-up shaft 30, and loosening of both side edges of the sheet-like member 20 can be suppressed.

  Further, the sheet-like member 20 is the side of the take-up shaft 30 that is exposed on the one side and the other side of the take-up shaft 30 alternately and has a large exposure range in the longitudinal direction. Bonded to the outer peripheral surface. For this reason, the sheet-like member 20 can be more strongly fixed to the winding shaft 30.

<Modification>
The sheet-like member 120a may be formed with a folded portion 126 in which a portion on one end edge portion (end edge portion on the storage side) is folded in multiple layers (see FIG. 10). The plurality of insertion hole portions 22 are formed in the folded portion 126. FIG. 10 shows a sheet-like member 120a in which double folded portions 126 are formed. The folded portion 126 is formed in a state in which two insertion hole portions 22 are arranged at a predetermined interval in a direction (winding direction) orthogonal to a direction in which the plurality of insertion hole portions 22 are arranged in a deployed state. (See FIG. 11). And the folding part 126 is formed by folding the part by the side of the one end edge part of the sheet-like member 120a in the form with which the two insertion hole parts 22 overlap. The predetermined interval between the two insertion hole portions 22 takes into account the distance from the insertion hole portion 22 to the end portion of the folded portion 126 when the portion on the one end edge side of the sheet-like member 120a is folded (small). It is better to set it so that it does not become too much.

  However, the folded portion is not limited to being doubled, and may be formed by being folded into multiples of three or more. In this case, the insertion holes 22 may be formed with the same number of insertion holes 22 as the number of folds of the folds in the winding direction in a state where the folds are expanded. .

  According to this configuration, since the insertion hole 22 is formed in the folded portion 126 in which the sheet-like member 120a is folded in a plurality of layers, the strength of the inner peripheral edge of the insertion hole 22 can be improved. That is, in the folded part 126 of the sheet-like member 120a, the inner peripheral edge part of the insertion hole part 22 is also formed in multiple layers, and the load can be dispersed and made smaller.

  Further, the folded portion 126 may be fixed in a folded state by stitching, adhesion with a double-sided adhesive tape or adhesive, or staple. When the folded portion 126 is fixed in a folded state, the workability of inserting the winding shaft 30 into the sheet-like member 120a is improved.

  Further, at least one portion in the direction (winding direction) orthogonal to one direction (width direction) in which the plurality of insertion hole portions 22 are arranged in the periphery of the insertion hole portion 22 is sewn on the sheet-like member 120b. A sewing reinforcement portion 128 may be formed (see FIGS. 12 to 14). FIG. 12 shows a circular sewing reinforcement portion 128 surrounding the outer periphery of the insertion hole portion 22 formed in a circular hole shape. The sewing reinforcement portion 128 may be set to have a diameter larger than that of the insertion hole portion 22 while matching the center with the insertion hole portion 22.

  In addition, it is preferable to use a sewing thread for forming the sewing reinforcement portion 128 that has at least a higher tensile strength than the main material constituting the sheet-like member 120b.

  According to this configuration, since the sewing reinforcement portion 128 is formed around the insertion hole portion 22 of the sheet-like member 120b, the strength of the portion around the insertion hole portion 22 can be improved.

  Further, the sheet-like member may be formed with a sewing reinforcement portion 128s on the drawing side of the insertion hole portion 22 as shown in FIG. 13, or may be sewn on the storage side of the insertion hole portion 22 as shown in FIG. A reinforcing portion 128t may be formed.

  Further, in the sheet-like member 120c, a portion (first portion 201) on one side of the plurality of insertion holes 22 in a direction (winding direction) orthogonal to one direction (width direction) in which the plurality of insertion holes 22 are arranged. However, a stitched portion 129 stitched along one direction with respect to the other side portion (second portion 202) of the plurality of insertion hole portions 22 in the winding direction is formed (see FIGS. 15 and 16). . Here, the stitching portion 129 is formed over the entire width direction of the sheet-like member 120c. But the stitching | suture part may be formed partially in the width direction of the sheet-like member 120c (for example, in several places spaced apart). Moreover, only the both ends in the width direction of the sheet-like member 120c may be stitched to form a stitched portion. In this case, a stitching convex portion protruding in a direction orthogonal to the width direction may be formed on the first portion of the sheet-like member, and the convex portion may be stitched to the second portion.

  In addition, it is preferable to use the sewing thread for forming the stitching portion 129 that has a tensile strength higher than that of at least the main material constituting the sheet-like member 120c.

  According to this configuration, the strength around the insertion hole 22 of the sheet-like member 120c can be improved. That is, since the first portion 201 of the sheet-like member 120c is fixed to the second portion 202 in a form extending along the outer peripheral surface of the take-up shaft 30, the portion that receives the take-up shaft 30 of the sheet-like member 120c. The thickness is increased and the strength is improved.

  Further, the sheet-like member 20 has been described as an example in which the sheet-like member 20 is fixed to the winding shaft 30 by the double-sided adhesive tape 24 so as not to be relatively movable in the central axis direction of the winding shaft 30 and to be relatively non-rotatable around the central axis. However, it is not limited to this. For example, the sheet-like member 20 may be attached to the winding shaft 30 so as to be relatively movable in the central axis direction. In this case, in order to prevent the sheet-like member 20 from dropping in the central axis direction with respect to the winding shaft 30, a retaining member having an outer diameter larger than the plurality of insertion hole portions 22 is provided at both ends of the winding shaft 30. Also good. At this time, the sheet-like member 20 may be relatively rotatable around the central axis with respect to the winding shaft 30 or may not be relatively rotatable.

  Further, the sheet-like member 20 may be fixed to the winding shaft 30 so as not to be relatively rotatable around the central axis by using fixing means such as a rivet, a screw or an adhesive in addition to the double-sided adhesive tape 24. Further, it may be fixed so as not to be relatively movable in the central axis direction.

  Moreover, although the example which attaches the sheet-like member 20 with respect to the winding shaft 30 was demonstrated so far, the attachment object of the sheet-like member 20 may be another shaft. For example, in the sheet winding device 110, a drawer shaft 170 may be attached to the drawer side end of the sheet-like member 120d (see FIG. 17). That is, a plurality of insertion hole portions 122 are formed in the drawing-side end portion of the sheet-like member 120d along a direction orthogonal to the winding direction. And the drawer shaft 170 is attached to the sheet-like member 120d by the form which penetrates the drawer shaft 170 with respect to the some insertion hole part 122. FIG. Here, the sheet-like member 20 may be attached to the drawer shaft 170 so as to be relatively movable in the central axis direction or may be attached so as not to be relatively movable. Further, the sheet-like member 20 may be rotatable relative to the drawer shaft 170 around the central axis. This attachment method may be determined by the presence or absence of the fixing means described above.

  Further, the sheet-like member 20 has a side portion of the plurality of insertion hole portions 122 in one direction in which the plurality of insertion hole portions 122 are arranged so as to extend along the outer peripheral surface of the extraction shaft 170. A long plate-like member may be fixed along the edge portion in the vicinity of the portion.

Second Embodiment
The attachment structure with respect to the winding shaft 30 of the sheet-like member 220 according to the second embodiment will be described (see FIG. 18). Of the second embodiment, the configuration different from the first embodiment is only the shape of the insertion hole 222, and the other components are denoted by the same reference numerals and description thereof is omitted.

  The insertion hole 222 is formed in a cut shape along a direction that intersects (here, orthogonally intersects) one direction in which the plurality of insertion holes 222 are arranged in the sheet-like member 220. The insertion hole 222 is set to have a dimension that is larger than a half of the circumferential length of the winding shaft 30 (slightly larger here) in the extending direction. Then, the sheet-like member 220 is attached to the take-up shaft 30 in such a form that the take-up shaft 30 is inserted into each of the plurality of insertion holes 222.

  According to this configuration, since the insertion hole 222 has a cut shape, the insertion hole 222 can be formed more easily.

<Third Embodiment>
A structure for attaching the sheet-like member 320 according to the third embodiment to the take-up shaft 30 will be described (see FIG. 19). In the third embodiment, the configuration different from the first embodiment is only the shape of the insertion hole portion 322, and the other components are denoted by the same reference numerals and description thereof is omitted.

  The insertion hole portion 322 has a cut portion 323 along a direction intersecting (here, orthogonal) to one direction in which the plurality of insertion hole portions 322 are arranged in the sheet-like member 320, and both ends of the cut portion 323 in the extending direction. A shape including a pair of continuous circular hole portions 324 is formed. More specifically, the insertion hole 322 is set to have a dimension that is larger (slightly larger here) than half of the circumferential length of the winding shaft 30 in the extending direction of the cut portion 323. Then, the sheet-like member 320 is attached to the take-up shaft 30 in a form in which the take-up shaft 30 is inserted into each of the plurality of insertion holes 322.

  Further, since the insertion hole portion is formed in a shape including the cut portion 323 and a pair of circular hole portions 324 continuous at both ends in the extending direction, a tensile force acts on the sheet-like member. Moreover, the load concerning the peripheral part of the insertion hole can be further reduced.

<Fourth embodiment>
A mounting structure of the sheet-like member 420 according to the fourth embodiment with respect to the winding shaft 30 will be described (see FIG. 20). Of the third embodiment, the configuration different from the first embodiment is only the shape of the insertion hole 422, and the other components are denoted by the same reference numerals and description thereof is omitted.

  The insertion hole 422 is formed in a long hole shape in a direction intersecting with one direction in which the plurality of insertion holes 422 are arranged in the sheet-like member 420. In addition, the insertion hole portion 422 is formed in a shape in which both ends in the longitudinal direction are formed in an arc shape and both ends of a pair of straight lines are connected by a pair of arc-shaped portions protruding outward. The dimension is set to be larger than half the circumference of the winding shaft 30 (here, slightly larger).

  According to this configuration, since the insertion hole 422 is formed in a long hole shape, it is easy to insert the winding shaft 30 into the plurality of insertion holes 422. In addition, since both ends in the longitudinal direction of the insertion hole portion 422 are formed in an arc shape, even if a tensile force acts on the sheet-like member 420, the load on the peripheral edge portion of the insertion hole portion 422 is dispersed. It can be made smaller.

  Various other shapes can be adopted for the plurality of insertion holes of the sheet-like member as long as the shaft can be inserted.

  As mentioned above, although this invention was demonstrated in detail, above-described description is an illustration in all the phases, Comprising: This invention is not limited to it. The various modifications described above can be applied in combination as long as they do not contradict each other. And it is understood that the countless modification which is not illustrated can be assumed without deviating from the scope of the present invention.
