Description

The present invention relates to a runner that can slide along a rail while supporting a sheet member , a curtain device, and a sewing method .

  For example, as a runner slidable along the rail in a state in which a sheet member such as a curtain or a shade is suspended and supported, a mounting member in which the sheet member is attached to a distal end side of a connection portion slidably connected to the rail. Generally, a configuration in which a unit is provided is provided.

  In recent years, for example, a vehicle such as an automobile is configured such that a protrusion is not formed in the vehicle. Therefore, in a runner of a curtain device for a vehicle, in a state where the runner is connected to the rail, the mounting portion exposed to the outside of the rail is formed in a columnar shape, and the tip end portion is also formed in a spherical shape, and the protrusion is formed. It is configured to eliminate it.

  Further, when attaching the sheet member to the attachment portion, for example, if a hook is used like a curtain for a house, there is a possibility that the hook becomes a projection, so the sewing holes provided in the attachment portion are provided. And the sheet member is sewn with a sewing machine or the like.

  As such a runner, for example, as shown in Patent Literature 1 and the like, a configuration in which a connecting portion is formed in a disk shape or a column shape so as to easily slide on a rail is known.

  That is, the runner of Patent Document 1 has a configuration in which not only the attachment portion but also the connection portion are formed so that the outer peripheral surface is formed in a circumferential shape, and the entire runner has a circumferential surface.

It is preferable because the moldability can be ensured.

  The runner 3 includes a substantially cylindrical mounting portion 12 to which the sheet member 11 is mounted, and a connecting portion 13 provided on one axial side of the mounting portion 12 and engaged with the rail 2 to be slidably connected. have.

  The mounting portion 12 has a spherical end at the other end in the axial direction opposite to the connecting portion 13.

  Further, a sewing hole 14 penetrating in the radial direction is provided on the base end side of the spherical portion of the mounting portion 12, and is sewn to the sheet member 11 through the sewing hole 14.

  The connecting portion 13 has a sliding portion 15 having a diameter larger than the distance between the distal ends of the rail components 9 and being insertable into the rail portion 6, and a constricted portion having a diameter smaller than the distance between the distal portions of the rail components 9. 16 and has.

  The constricted portion 16 is integrally connected to the mounting portion 12 on one side in the axial direction, and is integrally connected to the sliding portion 15 on the other side in the axial direction.

  The constricted portion 16 is disposed between the distal ends of the rail components 9 in a state where the runner 3 is connected to the rail 2 and is movable between the distal ends of the rail components 9.

  The sliding part 15 has a small diameter part 17 connected to the constricted part 16 and a large diameter part 18 provided on the opposite side of the constricted part 16 of the small diameter part 17.

  The small diameter portion 17 is formed to have a larger diameter than the distance between the constricted portion 16 and the tip of the rail forming portion 9, and the large diameter portion 18 is formed to have a larger diameter than the small diameter portion 17. That is, the sliding portion 15 has a step portion 19 formed by the small diameter portion 17 and the large diameter portion 18 having different outer diameters.

  The runner 3 is connected to the rail 2 by inserting the small-diameter portion 17 and the large-diameter portion 18 into the rail portion 6, and the runner 3 connected to the rail 2 has the sliding portion 15 in the rail portion 6. It can slide.

  In the state where the sliding portion 15 is inserted into the rail portion 6, the sliding portion 15 is arranged at the center in the width direction of the rail portion 6 as shown in FIG. A state in which the sliding portion 15 is shifted from the center in the width direction of the rail portion 6, such as a case where the sliding portion 15 is inclined at an angle α with respect to the rail portion 6 as shown in FIG. May be.

  As shown in FIG. 4, when the sliding portion 15 is displaced from the center of the rail portion 6 in the width direction, the step portion 19 comes into contact with the inner peripheral surface of the rail portion 6. That is, the connecting portion 13 is such that the entire outer peripheral surface of the sliding portion 15 does not make surface contact with the inner peripheral surface of the rail portion 6, and the edge of the large diameter portion 18 of the sliding portion 15 and the corner of the small diameter portion 17 are formed. At least two points can be brought into contact with the inner peripheral surface of the rail component 9 by contact. Note that the point contact includes not only a state of strictly point contact but also a state of contacting substantially in a point shape without slightly contacting in a planar shape and a state of contacting in a slightly linear manner.

  The sliding portion 15 is provided with an engagement receiving portion 21 having a concave groove shape. The engagement receiving portion 21 linearly extends in the radial direction so as to pass through the center of the circular sliding portion 15 in a plan view, and is formed in parallel with the opening direction of the sewing hole 14.

  As shown in FIG. 5, the engagement receiving portion 21 can engage with the convex engagement portion 23 of the positioning jig 22 for positioning used when attaching the sheet member 11 to the attachment portion 12. By engaging the engagement receiving portion 21 with the engagement portion 23, the runner 3 is positioned and held with respect to the sewing machine and the sheet member 11.

  Next, the operation and effect of the embodiment will be described.

  When sewing the sheet member 11 to the runner 3, the sheet member 11 is arranged on the sewing machine, and the positioning jig 22 is fixed to the sheet member 11.

  By engaging the engaging portion 23 of the positioning jig 22 with the engaging receiving portion 21 of the connecting portion 13 of the runner 3, the runner 3 is positioned with respect to the sewing machine and the sheet member 11, and the sewing state is changed. Hold.

  By driving the sewing machine in a state where the runner 3 is positioned and the sewing state is held in this manner, the sewing machine needle 24 is reciprocated between the inside of the sewing hole 14 and the outside of the side edge of the mounting portion 12, The attachment portion 12 and the sheet member 11 are sewn while the thread 25 is passed through the sewing hole 14.

  According to the runner 3, since the connection portion 13 has the engagement receiving portion 21 that can be engaged with the engagement portion 23 of the positioning jig 22, the connection portion 13 is positioned at a predetermined position of the sheet member 11 in a predetermined direction. It is easy to hold the sewing state where the runner 3 is arranged. Therefore, when sewing with the sewing machine, displacement of the runner 3 from the sewing state due to impact or vibration and rolling of the runner 3 from the sewing state can be prevented, and the sheet member 11 can be easily sewn.

  Further, since it is easy to hold the sewn state of the runner 3, even if the outer diameter of the runner 3 as a whole is smaller than that of the runner 3 shown in FIGS. The sewing of the sheet member 11 is easy, and the degree of freedom in design can be improved. That is, in the runner having the conventional configuration, the smaller the design, the more difficult it is to hold the sheet member 11 in the sewn state when sewing, and the sewing operation between the runner and the sheet member 11 is more complicated. The runner 3 having the portion 21 can be positioned and held without being affected by the size of the runner 3 when sewing the runner 3 and the sheet member 11. Therefore, for example, in order to more firmly fix the rail 2 at a predetermined position using a screw having a relatively large diameter, the width between the rail portions 6 is designed to be relatively large, or a more compact rail 2 is designed. Even in such a case, the runner 3 can be designed according to the shape and size of the rail portion 6 of the rail 2.

  In the configuration shown in FIG. 6, the ratio of the width A of the inner edge of the rail portion 6 to the width B of the outer edge of the fixed portion 5 is 1: 3.8, which is smaller than the size of the rail 2. Therefore, the width A between the distal ends of the rail components 9 is designed to be small.

  In addition, the provision of the engagement receiving portion 21 on the sliding portion 15 makes it possible to maintain the sewing state with a simple configuration, and the sliding portion 15 is located inside the rail portion 6 when the curtain device 1 is installed. Therefore, no projection is formed outside the curtain device 1.

  Since the engagement receiving portion 21 has a concave groove shape parallel to the opening direction of the sewing hole 14, the opening direction of the sewing hole 14 is parallel to the sewing needle 24 when the engagement receiving portion 21 is engaged with the engagement portion 23. At the same time, the displacement of the sewing needle 24 in the lateral direction, which is the reciprocating direction of the sewing machine 24, can be locked by the engagement with the engagement portion 23, so that the sewing state can be more reliably maintained.

  The runner 3 can slide on the inner peripheral surface of the rail portion 6 when the runner 3 slides because the sliding portion 15 of the connection portion 13 can contact the inner peripheral surface of the rail portion 6 at two points. Resistance caused by the contact of the moving part 15 can be reduced, and slidability can be improved. That is, for example, even when the runner 3 is inclined with respect to the rail 2 when sliding the sheet member 11 with the curtain device 1, the sliding portion 15 of the runner 3 comes into surface contact with the inner peripheral surface of the rail portion 6. As compared with the case where the sheet member 11 is moved, the sliding resistance is small and the sheet member 11 can be moved smoothly.

  Further, since the sliding portion 15 contacts the inner peripheral surface of the rail portion 6 at two points, the state of the sliding portion 15 in the rail portion 6 is more stable than when the sliding portion 15 contacts at one point, for example. It's easy to do.

  In the above-described embodiment, the curtain device 1 is configured to be installed in the vehicle. However, the present invention is not limited to such a configuration, and may be, for example, a ship, an aircraft, and a building.

  The rail 2 has a ratio of a width dimension A of an outer surface of a distal end portion of the side wall portion 7 which is an outer edge portion of the fixing portion 5 to a width dimension B between distal end portions of the rail component portion 9 which is an inner edge portion of the rail portion 6. However, the configuration is such that A: B = 1: 2 to 1: 4. However, the configuration is not limited to such a configuration, and the shape of the rail 2 can be appropriately designed.

  The runner 3 has a configuration in which the mounting portion 12 has a substantially cylindrical shape. However, the configuration is not limited to such a configuration, and the shape of the mounting portion 12 can be appropriately designed.

  The sliding portion 15 is not limited to a configuration capable of contacting the inner peripheral surface of the rail portion 6 at two points, but may be a configuration that makes surface contact with the inner peripheral surface of the rail portion 6. In the case where the sliding portion 15 is in surface contact with the inner peripheral surface of the rail portion 6, the sliding portion 15 and the rail portion 6 are formed of a material having a small coefficient of friction so that the resistance due to the contact can be reduced. Preferably.

  Although the engagement receiving portion 21 is configured to be engageable with the engagement portion 23 of the positioning jig 22, the configuration is not limited to the configuration where the engagement receiving portion 21 is engaged with the positioning jig 22. It is only necessary that the engaging portion 23 can be engaged with the engaging portion 23 for positioning.

  The engagement receiving portion 21 is not limited to the configuration provided on the sliding portion 15 of the connection portion 13, and the location where the engagement receiving portion 21 is provided can be appropriately changed.

  Further, the configuration is not limited to the configuration in which the engagement receiving portion 21 is groove-shaped and the engagement portion 23 of the positioning jig 22 is convex, and the engagement receiving portion 21 and the engagement portion 23 can be engaged. Any configuration may be used.
