Description

  The present invention relates to a structure for attaching a curtain rail to a wall, ceiling, or window frame by a bracket.

  Conventionally, as a structure for attaching this type of curtain rail to a bracket, a hook portion that engages a convex portion on one side edge of the curtain rail is provided at the front end of the bracket body, and downward side plates are provided on both the left and right sides of the bracket body. And a claw portion that engages with the convex portion on the other side edge of the curtain rail is provided at the front end of the plastic block body, and the block body is provided on the lower surface of the bracket body so as to be movable in the front-rear direction. A bracket is disclosed (see, for example, Patent Document 1). The curtain rail bracket is configured such that the rear end of the spring is pressed against a spring receiving piece formed by cutting out a part of the bracket body, and the front end of the spring is in contact with a spring receiving recess provided in the block body. A stopper is provided on the bracket body, and a stopper claw that abuts against the stopper and restricts the movement of the block body due to the biasing force of the spring is provided on the block body. The block body includes a handle for retracting the block body against the urging force of the spring, and a temporarily fixing nail body having a front end substantially the same shape as the nail part below the nail part. Are provided respectively. Furthermore, a flexible portion made of a rubber-like elastic body such as synthetic rubber, natural rubber, or soft plastic formed in a block shape is fixed to the lower surface of the bracket body by an adhesive or other fixing means.

  In the curtain rail bracket configured as described above, when the curtain rail is attached to the bracket, the convex portion on one side edge of the curtain rail is engaged with the hook portion on the front end of the bracket body, and then the convex portion on the other side edge of the curtain rail. When the part is pushed upward from the lower part of the temporary fixing nail body, the temporary fixing nail body bends backward and gets over the convex part, and the temporary fixing nail body engages with the convex part and the curtain rail temporarily Stopped. As a result, the curtain rail can be temporarily fixed. When the other side edge of the curtain rail is pushed up strongly, the convex part presses the inclined surface of the claw part to retreat the block body against the urging force of the spring, and the claw part engages with the convex part and the curtain rail. Is stopped. As a result, the curtain rail can be securely fixed without being twisted. On the other hand, when removing the bracket from the curtain rail, if you put your fingertip on the handle to retract the block body against the urging force of the spring and release the engagement between the claw part and the convex part, the main stop will be released and the curtain will be released. The rail can be removed. As a result, the curtain rail can be removed easily and quickly. In this way, the curtain rail can be easily and quickly attached and removed with one touch. In addition, since the flexible part is compressed by the curtain rail at the time of permanent fastening, the lateral movement of the curtain rail can be prevented by the sliding resistance generated on the pressure contact surface, thereby removing the play of the curtain rail attached to the bracket. It can be done.

The spring body 32h is configured to urge the second locking portion 11h of the curtain rail 11 in a direction of pushing into the second temporary receiving portion 32e of the second bracket 32.

  1, 3, and 4 are a pair of retaining pieces provided at lower portions on both sides of the surface of the second bracket 32 that faces the wall 13 of the base 32 a. These retaining pieces 32k are paired when the base 32a of the second bracket 32 is housed in a portion surrounded by the top plate 23a, the pair of side plates 23b, 23b, and the pair of bottom plates 23e, 23e of the first bracket 21. By engaging with the base end surfaces (surfaces facing the wall) of the bottom plates 23e, 23e, they serve as stoppers that prevent the second bracket 32 from being detached from the first bracket 21. 1, 3, and 4 is an operation piece that protrudes downward from the lower surface of the base 32 a of the second bracket 32. In a state where the curtain rail 11 is locked to the second temporary receiving portion 32e or the second main receiving portion 32d of the second bracket 32, the operation piece 32m is resisted against the elastic force of the elastic body 24 as shown in FIG. ) And (b) when pulled in the direction of the broken line arrow, the second bracket 32 moves in a direction in which the press contact portion 32j of the spring body 32h is detached from the third locking portion 11i. The two receiving portions 32d are separated from the second locking portion 11h of the curtain rail 11. Thereby, the 2nd latching | locking part 11h of the curtain rail 11 can be made to detach | leave from the 2nd temporary receiving part 32e or the 2nd main receiving part 32d.

  A procedure for attaching the curtain rail 11 thus configured to the wall 13 via the bracket 12 will be described. First, the second bracket 32 is assembled to the first bracket 21. Specifically, the elastic body 24 is accommodated in the recess 32b of the second bracket 32, and a portion surrounded by the top plate 23a, the pair of side plates 23b, 23b, and the pair of bottom plates 23e, 23e of the first bracket 21 in this state. The second bracket 32 is accommodated, and the pair of retaining pieces 32k, 32k of the second bracket 32 are locked to the base end surfaces (surfaces facing the wall) of the pair of bottom plates 23e, 23e of the first bracket 21. As a result, the second bracket 32 is not detached from the first bracket 21. In this state, the bracket 12 is attached to the wall with screws 14.

  Next, after the first locking portion 11g of the curtain rail 11 is locked to the first receiving portion 23c of the first bracket 21, the second locking portion 11h is centered around the first receiving portion 23c. 2 When rotating in the direction approaching the temporary receiving portion 32e, the third locking portion 11i of the curtain rail 11 contacts the pressure contact portion 32j of the spring body 32h, and the second locking portion 11h of the curtain rail 11 is the second convex portion. Passing over 32g, it latches in the 2nd temporary receiving part 32e (FIG. 1 (a)). At this time, since the second bracket 32 moves in the direction approaching the wall 13 against the elastic force of the elastic body 24, the second locking portion 11h can get over the second convex portion 32g. In this way, the curtain rail 11 is temporarily fixed to the bracket 12. The elastic force (resin elasticity) of the leaf spring portion 32i of the spring body 32h at the time of temporary fixing is such that the first locking portion 11g of the curtain rail 11 is locked to the first receiving portion 23c of the first bracket 21 and the curtain rail. 11 is smaller than the elastic force (resin elasticity) of the leaf spring portion 32i of the spring body 32h when the second locking portion 11h is locked to the second main receiving portion 32d of the second bracket 32 (FIG. 1 and FIG. 1). 3), when the curtain rail 11 is temporarily fixed to the bracket 12, the elastic force of the leaf spring portion 32i of the spring body 32h causes the second locking portion 11h of the curtain rail 11 to become the second temporary receiving portion 32e of the second bracket 32. Acts in the direction of pushing. As a result, due to the elastic force of the elastic body 24, the second contact portion 32 j at the tip of the spring body 32 h pressed against the third locking portion 11 i of the curtain rail 11 and the second locking portion 11 h of the curtain rail 11 are received. Since the curtain rail 11 is sandwiched between the second temporary receiving portion 32e of the bracket 32 and the curtain rail 11 is temporarily fixed to the bracket 12, the curtain rail 11 is not dropped from the bracket 12 in the longitudinal direction. The slide can be adjusted smoothly.

  After the curtain rail 11 is slid and adjusted, the curtain rail 11 is rotated around the first receiving portion 23c and the second locking portion 11h is moved closer to the second main receiving portion 32d. As a result, the second locking portion 11h of the curtain rail 11 gets over the first convex portion 32f and locks to the second main receiving portion 32d, and also locks to the protrusion 23d of the first bracket 21 (FIG. 1B). )). At this time, since the second bracket 32 moves in a direction approaching the wall 13 against the elastic force of the elastic body 24, the second locking portion 11h can get over the first convex portion 32f. As a result, the curtain rail 11 is permanently fixed to the bracket 12. As a result, since the spring body 32h pushes down the curtain rail 11 with a relatively large force at the time of the final stop, the second locking portion 11h of the curtain rail 11 is locked to the protrusion 23d of the first bracket 21. The curtain rail 11 does not move in the longitudinal direction and does not rattle in the width direction.
