Description

  The present invention relates to a curtain runner that is slidable in a curtain rail, and more particularly to a curtain runner that includes a stopper that can be fixed at an arbitrary position.

  Conventionally, there is a curtain runner provided with a magnet at the tip of the curtain so that the curtain can be fixed at the fully closed position. However, such a magnet runner cannot be fixed at any position other than the fully closed position. Therefore, if the window is opened with the curtain partially opened, the position of the curtain may fluctuate due to wind. Further, in the fully open state of the curtain, generally, the upper and lower intermediate portions of the curtain are often bound and fixed by a binding band. However, even in such a state, the upper part of the curtain is closed to some extent by the kickback (repulsive force) of the curtain, and cannot be fully opened. Furthermore, from the viewpoint of indoor design etc., even when the curtain upper and lower intermediate parts are fixed with a cable tie and only the upper part of the curtain is largely closed, it is impossible to change the curtain layout in various ways. . Then, the following patent document 1 and the patent document 2 are proposed as a curtain runner which can be fixed in arbitrary positions.

  In patent document 1, it consists of the curtain runner arrange | positioned so that it can drive | work along a curtain rail, and the winding member arrange | positioned at the end of a curtain rail. The curtain runner includes a locking tool incorporating a stopper configured to be able to appear and retract. The locking tool includes a push button at the upper end thereof, and a switching mechanism similar to the knock type ballpoint pen inside thereof. A conversion hook is attached to the upper end of the push button. The conversion hook forms a receiving portion for hanging the curtain hook at the lower end thereof, and is provided with a stopper at the upper end thereof. Then, the curtain runner can be fixed at an arbitrary position by pressing the push button of the locking tool by pulling down the curtain and alternately switching the state of the stopper by the switching mechanism.

  In Patent Document 2, in a curtain runner that is slidable in the curtain rail, a slide member that is movable up and down and is always urged upward by a spring is provided inside the curtain runner body, and the slide member is directed upward. A lock member that presses against the lower surface of the rail when moved, a hook hole for hooking a curtain hook, and a latch mechanism that alternately holds the slide member at two positions, an open position in the upper direction and a lower position. The latch mechanism is switched by pulling down the curtain, and the curtain runner can be fixed at an arbitrary position.

  In Patent Literature 1 and Patent Literature 2, the curtain runner can be easily fixed at an arbitrary position by a curtain lowering operation. However, in Patent Document 1, a switching mechanism having a push button is provided, and in Patent Document 2, a latch mechanism is provided, and the curtain runner has a large number of parts and a complicated and large configuration. In this case, the manufacturing cost increases, and the curtain runner is conspicuous, leaving a problem in design.

  Therefore, the present invention solves the above-described problems, and an object thereof is to provide a curtain runner that has a simple and compact configuration and can be easily fixed at an arbitrary position.

  The present invention is a curtain runner that is slidably movable in a curtain rail, the runner main body disposed in the curtain rail, a hook member on which the curtain hook is hooked, and the runner main body in pressure contact with the curtain rail And a stopper piece that can be fixed at an arbitrary position. The runner body has a through-hole penetrating vertically. The hook member includes a hook portion and a shaft portion continuous above the hook portion, and the shaft portion is inserted into the through hole of the runner body so as to be movable up and down. The length dimension of the shaft part of the hook member is larger than the height dimension of the runner body, and the stopper piece is provided at the upper end of the shaft part. The through hole includes a small-diameter portion that allows only insertion of the shaft portion of the hook member, and a large-diameter portion that is continuous above the small-diameter portion and is larger than the diameter of the shaft portion of the hook member. A compression spring is wound around the shaft portion of the hook member between the small diameter portion and the stopper piece, and the hook member and the stopper piece are always urged upward.

  The curtain runner is normally fixed by the stopper piece being pressed against the ceiling wall of the curtain rail, but the curtain hung on the hook portion of the hook member is used as the urging force of the compression spring. By simply pulling it down, it is possible to release the fixed state by separating the stopper piece from the curtain rail, and the curtain runner can be easily fixed at any position by simply sliding the curtain runner back and forth. Therefore, even if the window or door is opened with the curtain closed halfway (opened), the position of the curtain is not displaced by the wind. Even when the curtain is fully open, it can be fully opened against the kickback force (repulsive force) of the curtain. Moreover, since it can be fixed at an arbitrary position, the degree of freedom of layout in the curtain holding state is also improved.

  The small diameter portion at the lower end of the through hole has a diameter that allows the shaft portion of the hook member to be inserted, and is smaller than the size of the hook portion of the hook member. Therefore, in the most basic structure, the upper protrusion limit of the hook member is a position where the hook portion comes into contact with the lower surface of the runner body. That is, the hook member is restricted from coming off from the runner body by the hook portion at the lower end thereof. However, in this case, there is a possibility that the runner body may be damaged due to deformation by the hook portion by repeating the raising and lowering operation of the hook member. Therefore, although not necessarily required, it is preferable to provide a regulating piece that is larger than the diameter of the small-diameter portion of the through hole and that can contact the lower surface of the runner body at the lower end portion of the shaft portion of the hook member.

  The curtain runner is preferably provided with a pair of left and right rollers to smoothly slide the curtain runner. In this case, the position and number of the rollers are not particularly limited, but the through hole can be rolled in the curtain rail before and after the through hole after the through hole is formed in the front and rear central portion of the runner body. It is preferable to provide a pair of right and left rollers.

  According to the present invention, the hook member provided with the stopper piece at the upper end is inserted into the through hole formed in the runner body, and the hook member is simply urged upward by the compression spring. . Therefore, the number of parts of the curtain runner is small and assembly is easy, and the manufacturing cost can be reduced. Moreover, it is compact because of its simple structure, and even if it is mounted on a curtain rail, the curtain runner does not stand out and is excellent in design. Moreover, because of such a simple structure, it can be easily mounted on an existing curtain rail and can be easily replaced with an existing curtain runner.

  If the restriction piece is provided at the lower end portion of the shaft portion of the hook member, the restriction member restricts the hook member from coming off the runner body. Thereby, it is possible to prevent the runner body from being damaged by the hook portion. Further, the upper protrusion limit of the hook member and the stopper piece can be designed depending on the position where the restriction piece is provided.

  If a through hole is drilled in the front and rear center of the runner body, and a pair of left and right rollers are provided before and after the through hole, the curtain runner slides smoothly and the lifting and lowering operation of the hook member is stable. Can be done.

It is a side view of a curtain runner. It is a top view of a curtain runner. It is a vertical front view of the state mounted to the curtain rail. It is a front view around a window showing an example of a curtain layout. It is a front view around the window showing the fully open state of the curtain.

  Hereinafter, typical examples of the curtain runner according to the present invention will be described with reference to the drawings. However, the present invention is not limited thereto, and various modifications can be made without departing from the scope of the present invention. . As shown in FIGS. 1 to 3, the curtain runner 1 includes a runner body 10 that is slidably arranged in the curtain rail 40, a hook member 20 that is inserted into the runner body 10 so as to be movable up and down, and a hook member 20. A stopper piece 30 provided at the upper end of the stopper piece 30 and a compression spring 31 for biasing the stopper piece 30. The stopper piece 30 is capable of fixing the runner body 10, that is, the curtain runner 1 at an arbitrary position by being pressed against the inner surface of the curtain rail 40.

  The runner body 10 is a resin molded product, and a through-hole 11 penetrating vertically is formed in a central portion of the runner body 10 in the planar direction (front-rear and left-right directions). In the present invention, the front / rear and left / right directions are based on the direction shown in FIG. 2, the front / rear direction coincides with the axial direction of the curtain rail, and the right / left direction coincides with the width direction of the curtain rail. The through hole 11 includes a small-diameter portion 11 a that faces the lower surface of the runner body 10 and a large-diameter portion 11 b that continues above the small-diameter portion 11 a and reaches the upper surface of the runner body 10. A pair of left and right rollers 12 and 12 are provided before and after the through hole 11. Each roller 12 is rotatable about a shaft pin 13 and is provided on the left and right side surfaces of the runner body 10. A flange portion 10a is formed at the lower end of the runner main body 10 so as to protrude from the central portion in the left-right direction toward both left and right outwards. The width dimension of the flange portion 10 a is larger than the width dimension of the slide groove 41 of the curtain rail 40.

  The hook member 20 includes a hook portion 20a at a lower end portion thereof and a shaft portion 20b integrally continuous above the hook portion 20a, and the shaft portion 20b is inserted into the through hole 11 of the runner body 10 from below. Has been. A length dimension of the shaft portion 20b is larger than a height dimension of the runner body 10 (length dimension of the through hole 11), and an upper end thereof protrudes upward from the runner body 10 (through hole 11). The diameter of the small-diameter portion 11a of the through hole 11 is substantially the same (slightly larger) as the diameter of the shaft portion 20b, and only allows the shaft portion 20b to be inserted. On the other hand, the diameter of the large diameter portion 11b of the through hole 11 is slightly larger than the diameter of the shaft portion 20b. The hook portion 20a is located below the runner body 10, and a curtain hook (not shown) is hooked on the hook portion 20a. The curtain hook is engaged with a curtain not shown. In addition, although the hook part 20a in a present Example is an annular ring shape, the shape will not be specifically limited if it is a shape which can latch a curtain hook.

  Further, an annular ring-shaped restricting piece 21 is provided at the lower end portion of the shaft portion 20b (in the present embodiment, directly above the hook portion 20a). The restricting piece 21 is larger than the diameter of the through hole 11 (particularly, the small diameter portion 11a), and the restricting piece 21 comes into contact with the lower surface of the flange portion 10a of the runner body 10 so that the upper movement limit of the hook member 20 is extended. The upper protrusion limit of a stopper piece 30 to be described later is restricted. Further, the restricting piece 21 also has a function as a washer for preventing the runner body 10 from being damaged. The restricting piece 21 may only be inserted through the shaft portion 20b, but is preferably joined and fixed to the shaft portion 20b by bonding, welding, press-fitting, screwing, or the like. In particular, as long as it is fixed to the shaft portion 20b, the upper protrusion limit of the hook member 20 and the stopper piece 30 can be designed depending on the arrangement position of the restriction piece 21.

  A disc-shaped stopper piece 30 is provided on the upper end of the shaft portion 20 b of the hook member 20. The stopper piece 30 is larger than the diameter of the shaft portion 20 b of the hook member 20. The stopper piece 30 can be joined to the shaft portion 20b by adhesion, welding, or the like, or can be screwed together. The stopper piece 30 is not particularly limited as long as it is a material having a certain rigidity, such as metal, synthetic resin, ceramics, or wood, but in order to improve the stopper effect, a rubber material having a high friction coefficient is disposed on the upper surface. Is preferred. In this embodiment, no rubber material is provided. Moreover, although the upper surface of the stopper piece 30 may be flat, it is also preferable to provide a plurality of protrusions and protrusions.

  A compression spring 31 is wound around the shaft portion 20 b of the hook member 20 between the upper surface of the small diameter portion 11 a of the through hole 11 including the large diameter portion 11 b of the through hole 11 and the lower surface of the stopper piece 30. . Thereby, the hook member 20 and the stopper piece 30 are always urged upward. The outer diameter of the compression spring 31 and the diameter of the large diameter portion 11b of the through hole 11 are substantially the same.

  When the curtain runner 1 having such a configuration is assembled, the shaft portion 20b of the hook member 20 is passed through the through hole 11 of the runner body 10 from below. At this time, the restriction piece 21 is inserted in advance into the shaft portion 20b. Next, after the compression spring 31 is fitted from above the shaft portion 20b, the stopper piece 30 is joined to the upper end of the shaft portion 20b. Before and after this, each roller 12 is pivotally supported by the shaft pin 13 to complete. As described above, the curtain runner 1 of the present invention is easy to manufacture because it has a fixing mechanism but has a small number of parts and a simple structure.

  The curtain runner 1 may be inserted from one end of the curtain rail 40 similarly to the conventional curtain runner. Then, the curtain hook is hooked on the hook portion 20 a of the hook member 20. In addition, although the curtain runner 1 of this invention should just distribute | arrange at the front-end | tip of a curtain at least, it is also preferable to distribute | arrange to the intermediate part and base end of a curtain. If it is arranged at the base end of the curtain, there is an advantage that a runner stopper is unnecessary. Further, if a plurality of curtains are arranged in the middle of the curtain, the degree of freedom in curtain layout is improved.

  When the curtain runner 1 is mounted on the curtain rail 40, as shown in FIG. 3, each roller 12 is placed on the lower wall of the curtain rail 40 so as to be able to roll. Located in. At this time, the flange portion 10a is located on the lower surface of the curtain rail 40, and the lower wall of the curtain rail 40 is sandwiched between each roller 12 and the flange portion 10a. Then, when the stopper piece 30 is biased upward by the compression spring 31, the stopper piece 30 is pressed against the top wall of the curtain rail 40 and the position of the curtain runner 1 is fixed.

  When the curtain is pulled downward against the urging force of the compression spring 31 from this fixed state, the hook member 20 is pulled downward. Then, the stopper piece 30 is also moved downward to be separated from the top wall of the curtain rail 40 and to be in a fixed release state. At this time, since the pair of left and right rollers 12 and 12 are arranged before and after the hook member 20, the lifting and lowering operation of the hook member 20 is performed stably. Then, the curtain is moved back and forth in the unlocked state in which the curtain is lowered downward, and the curtain runner 1 is slid to an arbitrary position. If the curtain runner 1 can be moved to an arbitrary position, the curtain may be released. Then, the hook member 20 and the stopper piece 30 are moved upward by the urging force of the compression spring 31, and the stopper piece 30 comes into pressure contact with the top wall of the curtain rail 40, so that the fixed state is obtained again. Thus, the curtain runner 1 of the present invention can be easily fixed by simply moving the curtain while pulling it down and releasing the curtain at any position without having a switching mechanism or a latch mechanism.

  If such a curtain runner 1 is used, for example, as shown in FIG. 4, the upper and lower intermediate portions of the curtain 45 are bound and held by a binding band 47, and only the upper portion of the curtain 45 is an imaginary line (two-dot line). ) Can be held at a position somewhat closed from the normal fully opened state, and the indoor design can be improved by the curtain layout. Reference numeral 46 denotes a window.

  Further, as shown by the phantom line (two-dot chain line) in FIG. 5, generally, if the curtain 45 is not bound by a tie band, the curtain 45 is slightly closed by the kickback (repulsive force) of the curtain 45 even in the fully opened state. End up. However, if the curtain runner 1 of the present invention is used, the curtain 45 can be fully opened against kickback without using a cable tie as shown by the solid line in FIG. Of course, even if the window 46 is opened with the curtain 45 closed to the intermediate position, the position of the curtain 45 does not fluctuate due to the wind.
