Description

  The present invention relates to a wrinkle stopper applied to a door or window that can swing and open, and more particularly to a wrinkle stopper having a wire as a regulating element.

  A ratchet stopper using a wire as a regulating element is known (see Patent Document 1). There, one end of the wire is fixed to the door frame via a ball chuck and an attachment fitting, and the other end of the wire is fixed to the door via an end fitting and an attachment plate for receiving the end fitting. The mounting bracket is formed in a horizontally long U-shape when viewed from above, and a ball chuck is screwed and fixed to one arm. A guide hole is provided in the other arm, and an end of a wire passing through the guide hole from the door side is inserted and connected to the ball chuck.

JP 2001-49930 A (paragraph number 0007, FIG. 3)

  The above-mentioned barrack stopper can freely change the limit opening amount of the door by adjusting the insertion amount of the wire into the ball chuck. However, when the door is opened, the wire bends in the shape of a letter at the outer surface of the guide hole of the mounting bracket. Easy to cut between. When the door that is about to open is swung open and swung to the fully open position by being blown by the wind, stress concentrates on the bent portion, so that the wire is easily damaged. Since the length of the cut wire is insufficient, there is no need to replace it with a new wire, and the replacement takes time and cost.

  An object of the present invention is to alleviate the bending of the wire when the door is opened and to improve the durability of the tacking fastener using the wire as a regulating element. Another object of the present invention is to provide an impact acting on the wire when the door that is about to open is swung open and swung to the fully open position or when the door is swung by the wind. An object of the present invention is to provide a tack stop that can relax and absorb force and bending external force to eliminate and protect the wire damage.

  In the present invention, one end of the wire 8 is fixed to one of the door 1 and the door frame 2, and the wire stopper 6 to which the free end of the wire 8 is inserted and fixed is fixed to the other. And the bending relaxation tool 7 which is arrange | positioned between the fixed end of the wire 8 and the wire connection tool 6, and eases the bending of the wire 8 is provided. The wire connector 6 includes a ball chuck 16 and a holder 17 that supports the ball chuck 16. The bending relaxation tool 7 includes a cylindrical flexible body 19 that can be bent and deformed, and a holder 17 that fixes and supports the flexible body 19 through which the wire 8 is inserted (Claim 1).

  The flexible body can be formed by a closely wound coil spring 19, and one end of the coil spring 19 in that case is screwed into a screw hole 27 formed in the holder 17 to fix the coil spring 19 to the holder 17. (Claim 2).

  The holder 17 can be integrally formed with a first arm 24 that supports the ball chuck 16 and a second arm 25 that supports the coil spring 19 (Claim 3).

  The ball chuck 16 can be attached to the holder 17 via a closely wound coil spring 40 that can be expanded and contracted (claim 4).

  In the present invention, the bending relaxation tool 7 is arranged between the fixed end of the wire 8 and the wire connector 6 so that the bent portion of the wire 8 can be supported by the flexible body 19. In the portion where the wire 8 is bent, the flexible body 19 is elastically deformed and resists the bending force of the wire 8 by the deformation stress. Therefore, the angle of the bent portion of the wire 8 becomes gentle by the amount of repulsive force received from the flexible body 19, and the wire 8 has to be bent along the deformed shape of the flexible body 19. As a result, it is possible to eliminate the bending of the wire 8 in a square shape at a steep angle, and to improve the durability of the tacking fastener (claim 1).

  When the flexible body is formed by the closely wound coil spring 19, the adjacent spring wires are in close contact with each other, so that there is no room for the spring wires to shrink and approach each other inside the bent portion, and the coil spring 19 is correspondingly increased. The bending stress of itself increases (this is easy to understand assuming that a coil spring having a gap between the spring wires is bent). Therefore, the bending force of the wire 8 can be eliminated more effectively by applying a larger repulsive force to the bent portion of the wire 8. When the tension of the wire 8 is released, the coil spring 19 can return to the linear posture by its own elasticity, and therefore, the coil spring 19 can be prevented from being buffered against the door 1 when the door 1 is closed. (Claim 2).

  When the first arm 24 and the second arm 25 are integrally formed on the holder 17 and the ball chuck 16 and the coil spring 19 are supported by the arms 24 and 25, the ball chuck 16 and the coil spring are formed by only one holder 17. 19 can be supported, so that the number of component parts of the tacking fastener can be reduced, and the labor for attaching the holder 17 can be saved, so that labor during construction can be reduced. There is also an advantage that the three components of the ball chuck 16, the coil spring 19 and the holder 17 can be unitized.

  According to the hook stopper that supports the ball chuck 16 with the coil spring 40 that can be expanded and contracted, the shock that cannot be absorbed by the coil spring 19 can be absorbed by the coil spring 40 being expanded and deformed, and only the wire 8 can be absorbed. In addition, the external force acting on the ball chuck 16 can be relaxed, and the damage to the wire 8 and the ball chuck 16 can be eliminated. Accordingly, the reliability of the tacking fastener using the wire 8 as a regulating element is further improved, and for example, even when the tacking stopper is applied to a large and heavy door 1, the tacking action is reliably exhibited (claim). Item 4).

(Example 1) FIG. 1 thru | or FIG. 5 shows 1st Example of the wrinkle stopper which concerns on this invention. 1 and 2, reference numeral 1 denotes a door, 2 denotes a door frame, and 3 denotes a hinge that supports the door 1 so as to be swingable and openable. The hook stopper includes a bracket 4 fixed to the upper part of the inner surface of the door 1, a wire connector 6 and a bend relief 7 fixed to the upper flange of the door frame 2, one end fixed and held by the bracket 4, The free end is composed of a wire 8 that is inserted and connected to the wire connector 6 via the bending relaxation device 7. A cylindrical end fitting 9 is caulked and fixed to the end portion of the wire 8 on the bracket 4 side.

  In FIG. 3, the bracket 4 is composed of a Ω-shaped press fitting in which a semicircular locking seat 12 and left and right fastening seats 13 of the locking seat 12 are integrally formed. Is supported and supported. The locking seat 12 is formed with a clearance groove 14 that absorbs a change in posture of the wire 8 along its circumferential direction.

  3 and 4, the wire connector 6 includes a ball chuck 16 and a holder 17 that supports the ball chuck 16. The bending relaxation tool 7 includes a coil spring (flexible body) 19 and a holder 17 that supports the coil spring 19. In this embodiment, the ball chuck 16 and the coil spring 19 can be supported by only one holder 17.

  The holder 17 is a horizontally long U-shaped press fitting in which a first arm 24 and a second arm 25 are bent perpendicularly from one end and the other end of the fastening seat 23, and the ball chuck 16 is screwed into the first arm 24. A screw hole 26 for mounting is formed, and a screw hole 27 for screwing and mounting the coil spring 19 to the second arm 25 is formed. By attaching the fastening seat 23 to the upper collar of the door frame 2 and fastening it with screws, the holder 17 is fixed in a posture in which the arms 24 and 25 are vertical.

  The ball chuck 16 includes a case 31 having an inner surface formed with a tapered wall 30, a ball holder 33 that is inserted into the case 31 to hold three steel balls 32, and the ball holder 33 is attached to the tapered wall 30. A compression coil-type spring 34 that is pressed and urged toward the end, and a plug 36 that is screwed into a screw hole 35 on the inner surface of the case. The plug 36 serves both as a spring holder for receiving one end of the spring 34 and a fastener for fixing the ball chuck 16 to the first arm 24.

  In a normal state, the three balls 32 are pushed by the tapered wall 30 and moved to the center of the ball holder 33, and the wire 8 inserted into the insertion hole 37 of the ball holder 33 is clamped and fixed. When the operation shaft 38 of the ball holder 33 protruding from the end of the case 31 is pushed against the biasing force of the spring 34, the clamped state by the ball 32 can be released. The ball chuck 16 is integrated with the holder 17 by screwing the plug 36 into the screw hole 26 on the first arm 24 side.

  The coil spring 19 is formed of a closely wound compression coil spring. As shown in FIG. 4, one end of the coil spring 19 is screwed into the previous screw hole 27, and a lock nut is formed on the peripheral surface of the coil spring 19 protruding from the screw hole 27. The second arm 25 is fixed by screwing 28.

  As described above, when the bending relaxation tool 7 is disposed between the ball chuck 16 and the end fitting 9 and the bent portion of the wire 8 is supported by the coil spring 19, the door 1 is moved as shown in FIGS. In the opened state, the coil spring 19 is flexibly deformed and repels the bending of the wire 8, so that the wire 8 can be prevented from being bent into a square shape. The end fitting 9 supported by the bracket 4 follows the opening operation of the door 1 and rotates in the tensioning direction of the wire 8 inside the locking seat 12. The movement of the wire 8 at this time is absorbed by the escape groove 14. Since it can do, the bending of the wire 8 in the door 1 side can also be eliminated.

(Example 2) FIG. 6 and FIG. 7 show Example 2 of a tack stop device according to the present invention. In this case, the ball chuck 16 is fixed to the holder 17 via a cylindrical elastic body. For example, a closely wound coil spring 40 is used as the cylindrical elastic body.

  The pitch of the coil spring 40 is made to coincide with the pitch of the screw 35 formed on the inner surface of the case 31, and the coil spring 40 is screwed into the screw 35 with the collar 41 fitted to the inner surface of the end portion thereof. Yes. Since others are the same as those of the first embodiment, the same members are denoted by the same reference numerals and the description thereof is omitted.

  The collar 41 is integrally provided with a cylindrical shaft 42 that fits into the inner surface of the coil spring 40 and a flange 43 that projects from one end of the cylindrical shaft 42, and the flange 43 contacts the end of the coil spring 40. Thus, the coil spring 40 is positioned. The collar 41 also serves as a spring receiver that receives one end of the spring 34 of the ball chuck 16.

  When the coil spring 40 that has received an external force is contracted and deformed, the coil spring 40 may be separated from the thread of the screw 35 and separated. In order to prevent such separation of the coil spring 40, a collar 41 is arranged on the inner surface of the coil spring 40 to restrict the coil spring 40 from being deformed in a reduced size. In the ball chuck 16, the free end of the coil spring 40 is screwed into the screw hole 27 of the first arm 24 of the holder 17, and a lock nut 45 is screwed into the peripheral surface of the coil spring 40 protruding from the screw hole 27, thereby 25 is fixed.

  As described above, when the ball chuck 16 is fixed to the holder 17 via the coil spring 40, the coil spring 19 can be expanded and deformed to absorb the impact when the door 1 is suddenly opened as shown in FIG. 8 and the ball chuck 16 can be prevented from acting excessively.

  In addition to the above embodiments, flexible pipes can be applied as the flexible body 19 and the elastic body 40. The end fitting 9 can be formed in a spherical shape. The bracket 4 only needs to have a structure that can rotatably support the end fitting 9, and the structure is not limited to the structure described in the embodiment. One end of the wire 8 on the door 1 side only needs to be fixed to the door 1. For example, the tip of the wire 8 can be formed in an annular shape and directly attached with a screw or the like. The wire 8 may be inserted into a plate provided with a through hole for the wire 8 and the tip may be prevented from coming off, and then the plate may be fixed to the door 1. Since the holder for the ball chuck 16 and the holder for the coil spring 19 can be provided separately, the structure of the holder 17 is not limited to the structure described in the embodiment. The bracket 4 and the holder 17 do not need to be press fittings, respectively.
