Description

  The present invention relates to a structure in which a ring-shaped curtain runner for suspending a curtain movably along a curtain pole or curtain rail is assembled to the curtain pole or curtain rail.

  Conventionally, what cut | disconnected the side part of the annular part of the runner of a decoration curtain pole is disclosed (for example, refer patent document 1). In this runner, the width of the notch is formed smaller than the outer diameter of the curtain pole. Further, the arm portion of the bracket is located at a position between the cutout portions of the runner, and the pole support portion is formed small so as not to prevent the runner from running. In the curtain pole and the runner configured as described above, since the movement of the runner is not hindered by the bracket, more brackets can be used than the conventional decorative curtain pole. As a result, the strength of the pole and bracket can be set to the same level as that of a general pole and bracket.

  In addition, it has a substantially ring-shaped ring part that is elastic and cut at one point, and an arm part that is continuously connected to the upper part of the ring part, and a hook insertion hole is provided in the lower part. A curtain runner for a curtain pole is disclosed in which the gap between the two ends is expanded so that the curtain pole can be loosely fitted (see, for example, Patent Document 2). With a curtain runner for a curtain pole configured in this way, there is no need to install the curtain pole after a predetermined number of curtain runners have been loosely fitted to the curtain pole as in the past, and only the curtain pole is installed alone. After that, without removing the stopper or bracket, a predetermined number of curtain runners can be immediately fitted to the already installed curtain poles with their fingers spread between the cut ends of the ring part. As a result, the curtain runner can be handled easily.

  In the assembly structure according to the first aspect of the present invention, when both ends of the cutout portion of the curtain runner are pressed against the outer peripheral surface of the curtain pole or curtain rail, a part of the runner is elastically deformed, whereby the runner is The runner can be loosely fitted on the pole or rail. As a result, the runner can be easily attached to or detached from the pole or the like without removing the caps attached to both ends of the pole or the like. Also, when a pole is attached to the wall of a room without hanging the curtain on the runner, even if the runner moves or rotates with respect to the pole etc., a part of the runner is elastically deformed to remove the runner from the pole etc. Since the force is not so great that the runner is separated, or the opening size of the notch portion of the runner does not become larger than the outer diameter of the pole or the like, the runner is not detached from the pole or the like. Also, when the curtain is hung on the runner loosely fitted on the pole, etc., when the pole is attached to the wall of the room, etc., the weight of the curtain acts unintentionally in the direction of detaching the runner from the pole, Or after attaching the above-mentioned pole etc. to the wall of the room and attaching the curtain to the runner, when opening and closing the curtain, even if the force in the direction to detach the runner from the pole etc. acts on the runner unintentionally, The force due to the curtain's own weight and the curtain opening / closing operation is not so large that the runner is elastically deformed to disengage the runner from the pole, etc., or the opening size of the notch of the runner is larger than the outer diameter of the pole etc. Since there is nothing, the runner will not leave the pole. In addition to the weight of the curtain, if the force due to the opening and closing operation of the curtain acts on the runner, the entire runner is elastically deformed, spreading between the cut ends of the ring portion, and the runner may be detached from the pole. Compared with the curtain runner for a conventional curtain pole, in the present invention, the combined force of the weight of the curtain and the force of the curtain opening / closing operation is not limited to the weight of the curtain, even if the force of the curtain opening / closing operation acts on the runner. Because the runner is not large enough to elastically deform a part of the runner and the runner is detached from the pole, etc., or because the opening size of the notch of the runner does not become larger than the outer diameter of the pole etc., the runner is detached from the pole etc. Never do.

  In the assembly structure according to the second aspect of the present invention, when both ends of the cutout portion of the curtain runner are pressed against the outer peripheral surface of the curtain pole or curtain rail, the elastic deformation means is elastically deformed. Can be detached from the pole or rail, or the runner can be loosely fitted onto the pole or rail. As a result, the runner can be easily attached to or detached from the pole or the like without removing the caps attached to both ends of the pole or the like. Also, when the pole is attached to the wall of the room without hanging the curtain on the runner, even if the runner moves or rotates with respect to the pole etc., the elastic deformation means is elastically deformed and the runner is detached from the pole etc. Since the force is not so large that the runner does not become larger than the outer diameter of the pole or the like, the runner is not detached from the pole or the like. Furthermore, when the pole is attached to the wall of the room while the curtain is suspended from the runner loosely fitted to the pole etc., the weight of the curtain acts unintentionally in the direction of separating the runner from the pole etc. Or after attaching the above-mentioned pole etc. to the wall of the room and attaching the curtain to the runner, when opening and closing the curtain, even if the force in the direction to detach the runner from the pole etc. acts on the runner unintentionally, The force due to the curtain's own weight or the opening / closing operation of the curtain is not so large that the elastic deformation means is elastically deformed to disengage the runner from the pole, or the opening size of the notch of the runner is larger than the outer diameter of the pole etc. As described above, the runner will not leave the pole or the like.

  In the assembly structure according to the third aspect of the present invention, when the projection of the curtain runner is inserted into the long groove of the curtain rail and the runner is rotated around the projection, the elastic deformation means is elastically deformed. The runner can be detached from the rail, or the runner can be loosely fitted to the rail. As a result, the runner can be easily attached to and detached from or attached to the rail without removing the caps attached to both ends of the rail. Also, when the rail is attached to a room wall or the like without hanging the curtain on the runner, even if the runner moves or rotates with respect to the rail, the elastic deformation means is elastically deformed so that the runner is detached from the rail. Since the force does not act, or the opening size of the notch portion of the runner does not become larger than the outer diameter of the rail, the runner does not come off the rail. Furthermore, when the rail is attached to the wall of the room, etc., with the curtain suspended from the runner loosely fitted to the rail, the runner protrusion is unintentionally inserted into the long groove of the rail, and the curtain's own weight is removed from the runner from the rail. If the rail is attached to the wall of the room and the curtain is attached to the runner, and then the curtain is opened and closed, the runner's protrusion will unintentionally Even if the force in the direction of removing the runner from the rail is inserted into the long groove and the runner acts on the runner unintentionally, the force of the curtain's own weight or the opening / closing operation of the curtain elastically deforms the elastic deformation means, and the runner is detached from the rail. As described above, the runner must be detached from the rail because the opening size of the notch of the runner is not larger than the outer diameter of the rail. No.

<First Embodiment>
As shown in FIG. 1, the curtain pole 11 is formed in a cylindrical shape using wood, plastic, metal, or the like, and a ring-shaped curtain runner 12 for suspending a curtain (not shown) movably along the pole 11 is provided. It is loosely fitted to the pole 11. The runner 12 is formed with a notch 12a by notching a part of the ring shape. The runner 12 is provided at at least one of a runner body 13 having rigidity and a substantially inverted C shape and a pair of end portions of the runner body 13 forming the notch 12a. Elastic deformation means 14 that elastically deforms so that the opening size of the pole 11 becomes larger than the outer diameter of the pole 11. The runner body 13 is inserted into a runner rigid body 13a having a substantially inverted C shape made of a light alloy such as an aluminum alloy and having rigidity, and a C-shaped groove 13b extending along the inner peripheral surface of the runner rigid body 13a. It has a plastic substantially C-shaped runner sliding body 13 c whose peripheral surface is in contact with the outer peripheral surface of the pole 11.

  Of the pair of end portions of the runner main body 13 forming the notch portion 12a, that is, one end portion of the pair of end portions formed on the runner sliding body 13c due to the presence of the notch portion 12a, A first protrusion 13d that covers one end of 13a and extends in the direction of narrowing the notch 12a is provided. In addition, among the pair of end portions of the runner body 13 forming the notch portion 12a, that is, the other end portion of the pair of end portions formed in the runner sliding body 13c due to the presence of the notch portion 12a, A second protrusion 13e is provided which covers the other end of the body 13a and extends in the direction of narrowing the notch 12a. The elastic deformation means 14 is provided at one end portion of the runner sliding body 13c, and a pressure contact portion 14a that is in pressure contact with the outer peripheral surface of the pole 11, and a hinge that connects the pressure contact portion 14a to the end portion of the notch portion 12a. Part 14b. That is, the pressure contact portion 14a and the hinge portion 14b are provided by forming a cut 13f in the first protrusion 13d. The cut 13f is provided so as to extend in a direction substantially perpendicular to the shortest straight line connecting the first protrusion 13d and the second protrusion 13e. The first protrusion 13d, the second protrusion 13e, the pressure contact portion 14a, and the hinge portion 14b are integrally formed of plastic with the runner sliding body 13c. Further, the base end of the hanging tool 16 is inserted into the runner rigid body 13a and the runner sliding body 13c, and an annular ring 16a with which the hook 17 of the curtain engages is provided at the leading end of the hanging tool 16. The hanger 16 is inserted through the runner rigid body 13a and the runner sliding body 13c in the vicinity of the elastic deformation means 14 and the first protrusion 13d.

  On the other hand, the distance between the tip of the first protrusion 13d and the tip of the second protrusion 13e, that is, the distance between the outer surface of the pressure contact portion 14a and the tip of the second protrusion 13e is formed smaller than the outer diameter of the pole 11, and will be described later. It is formed larger than the thickness of the receiving portion 26 of the mounting bracket 18. The elastic deformation means 14 is such that the opening size of the notch 12a of the runner body 13 is smaller than the outer diameter of the pole 11 when the runner 12 is loosely fitted to the pole 11, and the outside of the pole 11 is removed when the runner 12 is attached to or detached from the pole 11. Elastically deforms to be larger than the diameter. That is, by pressing the pressure contact portion 14 a against the outer peripheral surface of the pole 11, the hinge portion 14 b is elastically deformed, the opening size of the notch portion 12 a is expanded, and the runner 12 is attached to and detached from the pole 11.

As shown in FIG. 2, when the outer diameter of the pole 11 is D ₁ (mm) and the width of the cut 13f formed in the first protrusion 13d is t ₁ (mm), the tip of the first protrusion 13d And the opening dimension B ₁ (mm) of the notch 12a of the runner body 13 are set within the range of (D ₁ −t ₁ ) <B ₁ <D _1. . Here, the reason why the opening dimension B ₁ is limited to the range of (D ₁ −t ₁ ) <B ₁ <D ₁ is that (D ₁ −t ₁ ) and below the runner even if the elastic deformation means 14 is elastically deformed. 12 it is difficult to loosely fit into or pawl 11 or is detached from the pole 11, there is a possibility that the hinge portion 14b exceeds D ₁ is the runner 12 without elastic deformation is detached unintentionally from the pole 11 Because. However, the opening dimension B ₁ is set to an optimum value within the range of (D ₁ −t ₁ ) <B ₁ <D ₁ depending on the material and thickness of the elastic deformation means 14.

  On the other hand, the pole 11 is attached to the wall 19 via the attachment bracket 18 (FIG. 1). The mounting bracket 18 includes a prismatic bracket body 21, a plate-like base portion 22 that is attached to the wall 19 by screws 23, and a base end latch that removably engages the base end of the bracket body 21 with the base portion 22. The tool 24 and the receiving part 26 which is provided in the front-end | tip of the bracket main body 21 and hold | maintains the pole 11 are provided. The bracket body 21 and the base portion 22 are preferably formed by a die casting method of a light alloy such as an aluminum alloy.

  As shown in FIGS. 3 to 5, the base end locking member 24 protrudes from the pair of upper claws 24 a protruding from the left and right of the upper base end of the bracket main body 21 and from the left and right of the lower base end of the bracket main body 21. A pair of lower claws 24b provided, a pair of upper receiving portions 24c provided at the upper portion of the base portion 22 and engaged with the pair of upper claws 24a, respectively, and a pair of lower claws 24b provided at the lower portion of the base portion 22 A pair of lower receiving portions 24d that engage with each other, a plastic lever 24f that is attached to the bracket body 21 with screws 24e and interposed between the bracket body 21 and the base portion 22, and a lever 24f that is attached to the base portion 22 are provided. A push-up means 24g for urging in the push-up direction, a pair of middle claws 24h projecting at the center in the vertical direction of the lever 24f, and a center in the vertical direction of the base portion 22 are formed. And a pair of middle hole 24i of the pair of middle claws 24h are respectively engaged. The push-up means 24g is interposed between the push-up body 24j slidably fitted in the base portion 22 in the vertical direction, and between the base portion 22 and the push-up body 24j, and pushes up the push-up body 24j. It consists of a compression coil spring 24k that urges.

  Further, as shown in FIG. 1, the receiving portion 26 is provided integrally with the bracket main body 21 at the tip of the bracket main body 21, and is formed to be bent in a substantially U shape so as to receive the lower surface of the pole 11. A stepped hole 26a is formed in the receiving portion 26, and a screw hole 11a is formed in the lower surface of the pole 11 facing the stepped hole 26a. A screw 27 is inserted into the stepped hole 26a, and the screw 27 is screwed into the screw hole 11a. As a result, the pole 11 is fixed to the receiving portion 26.

  A procedure for attaching the curtain pole 11 thus configured to the wall 19 via the attachment bracket 18 will be described. The push-up body 24g is assembled to the base portion 22 in advance. A lever 24f is attached to the base end of the bracket body 21 with screws 24e. First, the base portion 22 is attached to the wall 19 with a screw 23 (FIG. 3A). Next, the bracket body 21 is attached to the base portion 22 via the proximal end locking tool 24 (FIGS. 3B and 3C, FIGS. 4 and 5). Specifically, the upper pawl 24a is engaged with the upper receiving portion 24c as indicated by a two-dot chain arrow in FIG. 3B, and at the same time, the lower pawl 24b is indicated by a one-dot chain arrow in FIG. 3B. Engage with the lower receiving portion 24d (FIG. 4). As a result, the lever 24f depresses the push-up body 24j against the elastic force of the compression coil spring 24k, and the middle claw 24h engages with the middle hole 24i (FIG. 5). The bracket body 21 can be attached to the base portion 22 by such a simple operation. When the bracket main body 21 is removed from the base portion 22, the upper end of the lever 24 f is pulled away from the wall 19. As a result, the middle claw 24h is detached from the middle hole 24i, and the push-up means 24g pushes up the lever 24f, so that the upper claw 24a is detached from the upper receiving portion 24c and at the same time the lower claw 24b is separated from the lower receiving portion 24d.

  Next, after loosely fitting a plurality of runners 12 from one end side of the pole 11, caps (not shown) for retaining the runner 12 are attached to both ends of the pole 11. In this state, after placing the pole 11 on the receiving portion 26 of the mounting bracket 18, the screw 27 is inserted into the stepped hole 26a and screwed into the screw hole 11a, thereby fixing the pole 11 to the receiving portion 26 (FIG. 3 (c)). With such an extremely simple operation, the pole 11 can be fixed to the wall 19 via the mounting bracket 18. When the pole 11 is attached to the wall 19 with the curtain suspended from the runner 12 loosely fitted to the pole 11, the weight of the curtain acts unintentionally in the direction in which the runner 12 is detached from the pole 11. However, the dead weight of the curtain is not so great that the elastic deformation means 14 is elastically deformed to separate the runner 12 from the pole 11, so that the runner 12 does not separate from the pole 11.

  Furthermore, when the curtain hook 17 is engaged with the hanging tool 16 of the runner 12 to suspend the curtain, the outer diameter of the pole 11 is larger than the opening size of the notch 12a of the runner 12, so that the runner can be opened and closed even when the curtain is opened and closed. 12 can be prevented from unintentionally leaving the pole 11 (FIG. 1). When the runner 12 is moved along the pole 11, the runner 12 does not come into contact with the receiving portion 26, and the cutout portion 12a of the runner 12 passes through the receiving portion 26 of the mounting bracket 18. The runner 12 loosely fitted to the pole 11 can be moved over the entire length of the pole 11 regardless of the fixed position of the pole 11 by 18. In addition, when the curtain is opened and closed after the pole 11 is attached to the wall 19 and the curtain is attached to the runner 12, a force in the direction of separating the runner 12 from the pole 11 may act on the runner 12 unintentionally. The force due to the opening / closing operation of the curtain is not so great that the elastic deformation means 14 is elastically deformed to separate the runner 12 from the pole 11, so that the runner 12 does not separate from the pole 11.

Next, a procedure for adding the runner 12 to the pole 11 will be described. The runner 12 is pressed against the pole 11 in a direction in which both ends of the notch 12a of the runner 12 to be added are pressed against the pole 11 (FIG. 2B). Thus the hinge portion 14b of the elastic deformation means 14 the width of the cut 13f is reduced elastically deformed (FIG. 2 (c)), the outer diameter D ₁ of the opening dimension B ₁ is pawl 11 of the notch portion 12a of the runner 12 2c, the notch 13f of the first protrusion 13d returns to its original width due to the restoring force of the hinge portion 14b, and the runner 12 is loosely fitted to the pole 11, as shown by the two-dot chain line in FIG. Is done. The runner 12 can be loosely fitted to the pole 11 by such a simple operation. As a result, the runner 12 can be loosely fitted to the pole 11 without removing the caps attached to both ends of the pole 11.

Next, a procedure for replacing the runner 12 loosely fitted to the pole 11 will be described. First, the used runner 12 that needs to be replaced is removed from the pole 11. Specifically, the runner 12 is pulled in a direction in which both ends of the notch 12 a of the used runner 12 are pressed against the outer peripheral surface of the pole 11. Thus the hinge portion 14b of the elastic deformation means 14 the width of the cut 13f is reduced by elastic deformation, and the opening dimension B ₁ of the notch 12a of the runner 12 is equal to the outer diameter D ₁ of the pawl 11, spent Runner 12 leaves pole 11. Next, the new runner 12 is loosely fitted to the pole 11 in the same procedure as the above-described procedure for adding the runner 12. As a result, the runner 12 can be attached to and detached from the pole 11 without removing the caps attached to both ends of the pole 11.

<Second Embodiment>
6 to 10 show a second embodiment of the present invention. 6 to 10, the same reference numerals as those in FIGS. 1 to 3 denote the same components. In this embodiment, the curtain rail 51 is formed in a substantially cylindrical shape. The rail 51 has a long groove 51a extending in the longitudinal direction, whereby the cross-sectional shape of the rail 51 becomes a substantially inverted C shape. Inside the rail 51, two reinforcing ribs 51 b and 51 c having a substantially T-shaped cross section are provided so as to extend integrally with the rail 51 in the longitudinal direction of the rail 51. The rail 51 is preferably formed by extrusion or pultrusion of a light alloy such as an aluminum alloy.

  As in the first embodiment, the elastic deformation means 14 is formed on the runner sliding body 13c by virtue of the presence of the notch 12a among the pair of end portions of the runner body 13 forming the notch 12a. One of the pair of end portions (the first protrusion 13d) is provided. Similarly to the first embodiment, the second protrusion 13e is formed on the runner sliding body 13c by virtue of the presence of the notch 12a among the pair of end portions of the runner body 13 forming the notch 12a. Of the pair of end portions, the other end portion is provided. The first protrusion 13d is configured so as to be unable to be inserted into the long groove 51a by increasing the radius of curvature, and the second protrusion 13e is configured to be insertable into the long groove 51a while decreasing the radius of curvature. In this specification, in order to increase the radius of curvature of the first protrusion 13d so that the first protrusion 13d cannot be inserted into the long groove 51a, the first protrusion 13d is slightly inserted facing the long groove 51a of the rail 51. (Fig. 9). When the first protrusion 13d is slightly inserted into the long groove 51a of the rail 51, the first protrusion 13d slightly protrudes radially outward on the opposite side of the cross section of the rail 51 from the portion where the long groove 51a is formed. Is preferred. Thereby, even if the first protrusion 13d engages with the long groove 51a of the rail 51 and the elastic deformation means 14 is elastically deformed, the runner 12 can be prevented from unintentionally leaving the rail 51. Although the curtain runner 12 of the second embodiment is given the same reference numeral as the curtain runner of the first embodiment, the curtain runner 12 of the second embodiment is the same as the first embodiment. Not only the same shape as the curtain runner of the embodiment but also a similar shape may be used.

On the other hand, the distance between the tip of the elastic deformation means 14 and the tip of the second protrusion 13e, that is, the opening size of the notch 12a of the runner body 13 is formed smaller than the outer diameter of the rail 51 (FIG. 8). Further, when the second protrusion 13e is inserted into the long groove 51a, the elastic deformation means 14 is pressed against the outer peripheral surface of the rail 51 and elastically deforms in the direction of increasing the opening size of the notch 12a, so that the runner 12 becomes the rail 51. It is configured to be detachable (FIG. 7). Specifically, it is configured as follows. As shown in FIG. 7A, the width of the notch 13f of the first protrusion 13d when the elastic deformation means 14 is not elastically deformed is t ₁ (mm). In addition, when the second protrusion 13e is inserted into the long groove 51a of the rail 51, the first protrusion 13d is pressed against the outer peripheral surface of the rail 51, and the runner 12 is attached to and detached from the rail 51. Let t ₂ (mm) be the width of the cut 13f when it is greatly deformed, that is, when the width of the cut 13f of the first protrusion 13d is the smallest as shown by the solid line in FIG. And as the width t ₂ of the cut 13f is within a range of 0 ≦ t ₂ <t _1, the outer diameter of the rail 51, a long groove 51a of a width, the distance between the tip of the tip and the second protrusion 13e of the first protrusion 13d (Opening dimension of the notch 12a of the runner body 13), the outer diameter of the second protrusion 13e, and the like are set. Here, the width t ₂ of the cut 13f is limited to the range of 0 ≦ t ₂ <t ₁ is not unlikely in the width t ₂ of the cut 13f is less than 0, the hinge portion 14b is t ₁ or more This is because the runner 12 may be unintentionally detached from the rail 51 even without elastic deformation. However, the minimum width t ₂ of the notch 13f of the first protrusion 13d is set to an optimum value within the range of 0 ≦ t ₂ <t ₁ depending on the material and thickness of the elastic deformation means 14.

  On the other hand, the mounting bracket 58 includes a prismatic bracket main body 61, a plate-like base portion 22 attached to the wall 19 with screws 23, and a base end that releasably engages the base end of the bracket main body 61 with the base portion 22. The locking tool 24 and a tip locking tool 66 provided at the tip of the bracket body 61 and removably fitted into the long groove 51a of the rail 51 are provided.

  As shown in FIGS. 6 and 10, the front end locking member 66 is housed in a substantially crank-shaped frame portion 66a attached to the front end of the bracket main body 61 with screws 66b, and slidable in the frame portion 66a. The locking member sliding body 66c, the upper locking portion 66d that protrudes from the end of the frame portion 66a and engages with the upper edge of the long groove 51a of the rail 51, and the locking member sliding body 66c protrudes. A lower locking portion 66e that engages with the lower edge of the long groove 51a of the rail 51, a pressing means 66f that pushes the locking member sliding body 66c obliquely downward, and a lower surface of the locking member sliding body 66c. The locking member sliding body 66c has an operation protrusion 66g for pushing up the slantingly upward against the pushing force of the pushing-down means 66f. The frame portion 66a and the upper locking portion 66d are integrally formed by pressing a steel plate. The locking member sliding body 66c, the lower locking portion 66e, and the operation projection 66g are integrally formed of plastic. The push-down means 66f is a compression coil spring that is interposed between the frame portion 66a and the locking member sliding body 66c and biases the locking member sliding body 66c obliquely downward. The configuration other than the above is the same as that of the first embodiment.

  A procedure for attaching the curtain rail 51 thus configured to the wall 19 via the attachment bracket 58 will be described. The push-up body 24g is assembled to the base portion 22 in advance. Further, the lever 24f is attached to the base end of the bracket body 61 with screws 24e, and the distal end locking member 66 is attached to the tip of the bracket body 61 with screws 66b. First, the base portion 22 is attached to the wall 19 with screws 23. Next, the bracket main body 61 is attached to the base portion 22 via the proximal end locking member 24 as in the first embodiment (FIG. 10A). Next, after loosely fitting the plurality of runners 12 from one end side of the rail 51, caps (not shown) for retaining the runner 12 are attached to both ends of the rail 51. In this state, after the upper edge of the long groove 51a of the rail 51 is engaged with the upper locking portion 66d of the tip locking device 66 (FIG. 10A), the lower edge of the long groove 51a of the rail 51 is connected to the tip locking device. It is made to engage with the lower locking part 66e of 66 (FIG.10 (b)).

  At this time, if the upper surface of the lower locking portion 66e is tapered, the lower edge of the long groove 51a of the rail 51 is used as a locking tool by rotating the rail 51 in the direction of the solid line arrow in FIG. After the sliding body 66c is pushed up diagonally upward against the elastic force of the push-down means 66f, the lower edge of the long groove 51a of the rail 51 engages with the lower locking portion 66e of the tip locking tool 66 (FIG. 10). (B)). And since the lower latching | locking part 66e is urged | biased in the diagonally downward direction by the pressing means 66f, the rail 51 does not detach | leave from the attachment bracket 58 unintentionally. Further, since the long groove 51a of the rail 51 is located obliquely below the wall 19 side, it is hardly visible from the indoor side, and the appearance of the rail 51 is not impaired. With such an extremely simple operation, the rail 51 can be fixed to the wall 19 via the mounting bracket 58. When the rail 51 is attached to the wall 19 with the curtain suspended from the runner 12 loosely fitted to the rail 51, the second protrusion 13e of the runner 12 is unintentionally inserted into the long groove 51a of the rail 51. Even if the curtain's own weight acts unintentionally in the direction of detaching the runner 12 from the rail 51, the curtain's own weight is not so great as to cause the elastic deformation means 14 to elastically deform and detach the runner 12 from the rail 51. 12 does not leave the rail 51.

  Further, when the curtain hook 17 is engaged with the hanging tool 16 of the runner 12 to suspend the curtain, the long groove 51a of the rail 51 is displaced without engaging with the second protrusion 13e of the runner 12, so that the curtain can be opened and closed. The runner 12 can be prevented from unintentionally leaving the rail 51 (FIG. 6). When the runner 12 is moved along the rail 51, the runner 12 does not come into contact with the front end locking tool 66, and the cutout portion 12 a of the runner 12 passes through the front end locking tool 66 of the mounting bracket 18. Therefore, the runner 12 loosely fitted to the rail 51 can be moved over the entire length of the rail 51 regardless of the fixing position of the rail 51 by the mounting bracket 18. Further, after the rail 51 is attached to the wall 19 and the curtain is attached to the runner 12, the second protrusion 13e of the runner 12 is unintentionally inserted into the long groove 51a of the rail 51 when the curtain is opened and closed. Even if a force in the direction to detach the runner 12 from the rail acts unintentionally on the runner 12, the force due to the opening / closing operation of the curtain is not so great that the elastic deformation means 14 is elastically deformed to detach the runner 12 from the rail 51. The runner 12 never leaves the rail 51.

  Next, a procedure for adding the runner 12 to the rail 51 will be described. First, the second protrusion 13e of the runner 12 to be added is inserted into the long groove 51a of the rail 51 (FIG. 7A). In this state, the runner 12 is rotated around the second protrusion 13e, and the first protrusion is pressed against the outer peripheral surface of the pole (FIG. 7B). As a result, the hinge portion 14b of the elastic deformation means 14 is elastically deformed so that the width of the cut 13f gradually decreases and the width of the cut becomes the smallest (FIG. 7 (c)). The notch 13f of one protrusion 13d returns to its original width (FIG. 7 (d)), and the runner 12 is loosely fitted to the rail 51 as shown by the two-dot chain line in FIG. 7 (d). The runner 12 can be loosely fitted to the rail 51 by such a simple operation. As a result, the runner 12 can be loosely fitted to the rail 51 without removing the caps attached to both ends of the rail 51.

  Next, a procedure for replacing the runner 12 loosely fitted to the rail 51 will be described. First, the used runner 12 that needs to be replaced is removed from the rail 51. Specifically, after the second protrusion 13e of the used runner 12 is inserted into the long groove 51a of the rail 51, the runner 12 is rotated in the opposite direction. As a result, the hinge portion 14b of the elastic deformation means 14 is elastically deformed so that the width of the cut 13f gradually decreases, and after the width of the cut becomes the smallest, the cut 13f of the first protrusion 13d is deformed by the restoring force of the hinge portion 14b. Returning to the original width, the used runner 12 is detached from the rail 51. Next, the new runner 12 is loosely fitted to the rail 51 by the same procedure as the above-described procedure for adding the runner 12. As a result, the runner 12 can be attached to and detached from the rail 51 without removing the caps attached to both ends of the rail 51.

<Third Embodiment>
11 to 15 show a third embodiment of the present invention. 11 to 15, the same reference numerals as those in FIGS. 1 and 2 denote the same components. In this embodiment, the elastic deformation means 84 is pressed against the outer peripheral surface of the curtain pole 11 and the spring that biases the pressure contact 84a in the direction of narrowing the opening dimension of the notch 82a of the curtain runner 82. 84b (FIGS. 11 and 13 to 15). The runner 82 is provided at at least one of the runner body 83 having rigidity and a substantially inverted C shape and a pair of end portions of the runner body 83 forming the notch 82a. Elastic deformation means 84 that elastically deforms so that the opening dimension is larger than the outer diameter of the pole 11. The runner main body 83 is inserted into a runner rigid body 83a formed of a light alloy such as an aluminum alloy in a substantially inverted C shape and having rigidity, and a C-shaped groove 83b extending along the inner peripheral surface of the runner rigid body 83a. A plastic substantially C-shaped runner sliding body 83c whose peripheral surface is in contact with the outer peripheral surface of the pole 11;

  Of the pair of end portions of the runner main body 83 forming the notch portion 82a, that is, one end portion of the pair of end portions formed in the runner sliding body 83c due to the presence of the notch portion 82a is a runner rigid body. A first protrusion 83d is provided which covers one end portion of 83a and extends in the direction of narrowing the notch 82a. Further, among the pair of end portions of the runner body 83 forming the notch portion 82a, that is, the other end portion of the pair of end portions formed in the runner sliding body 83c due to the presence of the notch portion 82a, A second protrusion 83e is provided that covers the other end of the body 83a and extends in the direction of narrowing the notch 82a. The pressure contact portion 84a of the elastic deformation means 84 also serves as the first protrusion 83d. The second protrusion 83e is formed of plastic integrally with the runner sliding body 83c. A recess 83f extending in a substantially circumferential direction is formed at one end of the runner sliding body 83c, and a pressure contact portion 84a is slidably inserted along the longitudinal direction of the recess 83f (see FIGS. 11 and 12). ). A first spring hole 83g is formed in one end surface of the recess 83f, and a second spring hole 84c is formed in the pressure contact portion 84a. One end of the spring 84b is inserted into the first spring hole 83g, and the other end of the spring 84b is inserted into the second spring hole 84c. As a result, the pressure contact portion 84a is pressed against the other end of the recess 83f by the elastic force of the spring 84b.

  On the other hand, the distance between the tip of the first protrusion 83d and the tip of the second protrusion 83e, that is, the distance between the outer surface of the pressure contact portion 84a and the tip of the second protrusion 83e is such that the pressure contact portion 84a is pressed against the other end of the recess 83f. In this state, it is formed smaller than the outer diameter of the pole 11 and larger than the thickness of the receiving portion 26 of the mounting bracket 18. The elastic deformation means 84 is such that the opening dimension of the notch portion 82 a of the runner body 83 (the distance between the tip of the first projection 83 d and the tip of the second projection 83 e) is such that the runner 82 is loosely fitted to the pole 11. It is elastically deformed so as to be smaller than the outer diameter and larger than the outer diameter of the pole 11 when the runner 82 is attached to the pole 11. That is, by moving the pressure contact portion 84a of the elastic deformation means 84 to one end side of the recess 83f against the elastic force of the spring 84b, the opening dimension of the notch portion 82a is widened so that the runner 82 is attached to the pole 11. Configured. The configuration other than the above is the same as that of the first embodiment.

  Since the procedure for attaching the curtain pole 11 to the wall 19 via the attachment bracket 18 is substantially the same as in the first embodiment, repeated description will be omitted. When the pole 11 is attached to the wall 19 with the curtain suspended from the runner 82 loosely fitted to the pole 11, the weight of the curtain acts unintentionally in the direction in which the runner 82 is detached from the pole 11. However, the pressure contact portion 84a is kept in pressure contact with the other end side of the recess 83f by the elastic force of the spring 84b, and the opening size of the notch portion 82a of the runner 82 may be larger than the outer diameter of the pole 11. As a result, the runner 82 does not leave the pole 11.

  Further, when the curtain hook 17 is engaged with the hanging tool 16 of the runner 82 to suspend the curtain, the outer diameter of the pole 11 is larger than the opening size of the notch 82a of the runner 82. 82 can be prevented from unintentionally leaving the pole 11 (FIG. 11). When the runner 82 is moved along the pole 11, the runner 82 does not come into contact with the receiving portion 26 and the cutout portion 82 a of the runner 82 passes through the receiving portion 26 of the mounting bracket 18. The runner 82 loosely fitted to the pole 11 can be moved over the entire length of the pole 11 regardless of the fixed position of the pole 11 by 18. In addition, when the curtain is opened and closed after the pole 11 is attached to the wall 19 and the curtain is attached to the runner 82, even if a force in the direction of separating the runner 82 from the pole 11 acts on the runner 82 unintentionally. The pressure contact portion 84a is kept in pressure contact with the other end side of the recess 83f by the elastic force of the spring 84b, and the opening dimension of the notch portion 82a of the runner 82 does not become larger than the outer diameter of the pole 11. Therefore, the runner 82 does not leave the pole 11.

  Next, a procedure for adding the runner 82 to the pole 11 will be described. The runner 82 is pressed against the pole 11 in a direction in which both ends of the notch 82a of the runner 82 to be added are pressed against the pole 11 (FIG. 13). As a result, the pressure contact portion 84a of the elastic deformation means 84 moves to one end side of the recess 83f against the elastic force of the spring 84b (FIG. 14), and the opening dimension of the notch portion 82a of the runner 82 is equal to the outer diameter of the pole 11. After equalization, as shown in FIG. 15, the pressure contact portion 84 a moves to the other end side of the recess 83 f by the elastic force of the spring 84 b, and the runner 82 is loosely fitted to the pole 11. The runner 82 can be loosely fitted to the pole 11 by such a simple operation. As a result, the runner 82 can be loosely fitted to the pole 11 without removing the caps attached to both ends of the pole 11.

  Next, a procedure for replacing the runner 82 loosely fitted to the pole 11 will be described. First, the used runner 82 requiring replacement is removed from the pole 11. Specifically, the pressure contact portion 84a of the elastic deformation means 84 of the used runner 82 is moved to one end side of the recess 83f against the elastic force of the spring 84b. As a result, the opening dimension of the notch 82 a of the used runner 82 becomes larger than the outer diameter of the pole 11. In this state, the used runner 82 is removed from the pole 11. Next, the new runner 82 is loosely fitted to the pole 11 in the same procedure as the above-described procedure for adding the runner 82. As a result, the runner 82 can be attached to the pole 11 without removing the caps attached to both ends of the pole 11.

  In the first and second embodiments, the runner is attached to and detached from the pole or rail by the elastic deformation means being elastically deformed. However, even if the runner is elastically deformed, the runner can be attached to and detached from the pole or rail. Good. In the first to third embodiments, the pole or rail is fixed to the wall via the mounting bracket, but the pole or rail may be fixed to the ceiling or window frame via the mounting bracket. In the first embodiment, the pole is formed in a columnar shape. However, the pole is formed in a substantially columnar shape having a concave portion or a convex portion in a part of the outer peripheral surface, a cylindrical shape, or the outer peripheral surface. You may form in the substantially cylindrical shape which has a recessed part or a convex part in part. In the third embodiment, the pole is formed in a columnar shape. However, the pole is formed in a substantially columnar shape having a concave portion or a convex portion in a part of the outer peripheral surface, formed in a cylindrical shape, or one of the outer peripheral surfaces. You may form in the substantially cylindrical shape which has a recessed part or a convex part in a part, or you may form in the substantially cylindrical shape similar to 2nd Embodiment. Furthermore, in the second embodiment, the rail is attached to the mounting bracket so that the long groove is located obliquely below the wall side. However, the rail is attached to the mounting bracket so that the long groove faces the wall, or the long groove is The rail may be attached to the mounting bracket so as to be positioned obliquely above the wall side. In this case, it is necessary to change the attachment position of the lifting tool to the runner so that the notch portion of the runner passes through the tip locking tool of the mounting bracket.
