Description

  The present invention relates to a tilt stopper that uses a wire as a regulating element to regulate the opening limit of a door, a window, or the like.

  A tilt stopper using a wire as a regulating element is known from Patent Document 1. There, one end of the wire is fixed to the door frame via a ball chuck and a bracket, and an end fitting fixed to the other end of the wire is held by a bracket fixed to the door. A bending relief made of a coil spring is mounted on the wire lead-out portion of the bracket for the ball chuck. As described above, according to the tilt stopper provided with the bending relaxation device, the wire connecting the brackets at the shortest distance bends in a square shape at a steep angle at the lead-out portion from each bracket when the door is opened. Can be eliminated. The bracket for the end metal fitting is formed with a bell mouth-shaped relief portion that prevents the wire from being bent into a square shape.

  Patent Document 2 also proposes a similar stopper, in which an impact absorbing spring that receives an end fitting is arranged inside a cylindrical case, and the door that is about to open is covered with the wind to open the limit. In such a case, the shock absorbing spring is compressed and deformed, so that the shock force acting on the wire can be reduced.

Japanese Patent Laying-Open No. 2005-344385 (paragraph number 0024, FIG. 4) JP 2006-57438 A (paragraph number 0038, FIG. 4)

  As described above, according to the tilt stopper provided with the bending relaxation tool, it is possible to prevent the wire from being bent into a square shape when the door is opened, and to prevent the strength of the wire from being lowered. Further, in the tilt stopper provided with the shock absorbing spring, the shock acting on the wire can be mitigated by the shock absorbing spring when the door covered with the wind suddenly opens and swings.

  However, the meter box doors on the higher floors of apartment buildings and the doors of meter boxes provided in areas where gusts are likely to occur, even though the wire protection structure is provided as described above, There are not a few cutting accidents. Since the length of the cut wire is short, it is not only replaced, but also takes time and cost to replace. In addition, in the case of the tilt stopper provided with the shock absorbing spring, the door opened to the open limit position may suddenly close and move due to the reaction of the fully compressed shock absorbing spring, which opens and closes the door. You need to be very careful.

  The wire cutting accident as described above is considered to be caused by the fact that the wire is stretched and deformed due to repeated strong impact on the wire, and the strength gradually decreases. As long as the wire diameter is increased and the wire strength is increased, the wire cutting accident can be eliminated. But it creates new problems. Increasing the wire diameter can prevent a wire cutting accident, but as the wire strength improves, the bracket that receives the end fitting is deformed, or the door bar and the door wall to which the bracket is fastened are deformed. In particular, the door of the meter box has a simple structure compared to the entrance door and the like, and the structural strength of the entire door is small. Therefore, the impact load concentrates on the fastening part of the bracket, and the door wall surface may be greatly dented and deformed. The door thus deformed can only be replaced, but the cost required for the door replacement is much higher than the cost for the wire replacement.

  The object of the present invention is to prevent the wire that regulates the opening of a door covered with wind from being cut by receiving the opening impact of the door, and the door wall and the door side bracket are deformed by the opening impact, or An object of the present invention is to provide a tilt stopper that can surely prevent breakage. The object of the present invention is to eliminate the closing action of the door due to the reaction, which is inevitable when the opening shock of the door that has been blown by the wind can be relaxed and absorbed. Accordingly, it is an object of the present invention to provide a tilt stopper that can safely open and close the door.

  The tilt stopper of the present invention connects the wire holding body 6 fixed to the door 1, the wire holding body 7 fixed to the door frame 2, and both wire holding bodies 6, 7 to limit the opening limit of the door 1. The wire 5 to regulate is provided. When the door 1 is opened to the open limit, the wire holding body 6 on the side receiving the end fitting 9 fixed to the end of the wire 5 is shock-absorbing body 11 for relaxing and absorbing the opening shock of the door 1, and the shock-absorbing body 11 includes a bracket 13 that supports the motor 11. Therefore, the shock absorber 11 is characterized in that the shock absorber 25 made of low-rebound rubber is mainly used.

  The buffer body 25 is composed of a single block, and an insertion hole 29 through which the wire 5 passes is formed.

  The shock absorber 11 includes a buffer body 25 that is formed in a cylindrical shape, a support tool 26 that is attached to the bracket 13 to support the buffer body 25, and a metal bracket that is disposed at the protruding end of the buffer body 25 and receives the end metal fitting 9. 27.

  The bracket 13 includes a fastening wall 14, a pair of left and right side walls 15 that are continuous to the fastening wall 14, and a front wall 16 that connects the side walls 15. The three members of the metal fitting 27, the buffer body 25, and the support tool 26 are disposed between the pair of left and right side walls 15. The support 26 is received and held by one side wall 15 that is supported at both ends by the fastening wall 14 and the front wall 16.

  The support 26 includes a base block 31 that receives one end of the buffer 25 and a guide cylinder 32 that supports the buffer 25. The support fitting 27 is slidably guided and supported by a guide hole 21 and a guide tube 32 provided in one side wall 15.

  In the present invention, for example, the wire holder 6 fixed to the door 1 side is constituted by an impact absorber 11 that relaxes and absorbs the opening impact of the door 1, a bracket 13 that supports the impact absorber 11, and the like. The body 11 is mainly composed of a buffer body 25 formed of a low resilience rubber. As described above, according to the shock absorber 11 including the low-rebound rubber shock absorber 25, the shock absorber 25 receives the shock generated when the door 1 is suddenly opened to the open limit position by being blown by the wind. By compressing and deforming, since it can be relaxed and absorbed in an instant, it is possible to prevent an excessive impact load from acting on the wire 5. Therefore, even when the door 1 is repeatedly opened and swayed by the wind, it is possible to reliably prevent the wire 5 from being cut or stretched and deformed for a long period of time due to excessive tension. At the same time, the deformation of the bracket 13 and the wall surface of the door to which the bracket 13 is fastened can be eliminated at the same time. Further, the shock absorber 25 formed of low resilience rubber is hardly repelled in the state of being compressed and deformed by impact, so that the door closing operation can be wiped out due to the reaction of the shock absorber 25, and the door 1 can be safely removed. Moreover, it can be closed as intended by the user.

  According to the shock absorber 25 made of a single block having the insertion hole 29 for the wire 5 inside, the shock absorber is less than the case where the shock of the wire 5 is relaxed and absorbed by a plurality of shock absorbers 25, for example. The structure of 11 can be simplified and the cost required for manufacturing the tilt stop can be reduced accordingly. Since the impact force of the wire 5 inserted through the insertion hole 29 is received by the entire buffer body 25 via the end fitting 9, the entire buffer body 25 is compressed and deformed, so that the impact can be effectively relaxed and absorbed. Only the buffer body 25 can be miniaturized.

  According to the shock absorber 11 formed of a buffer body 25 formed in a cylindrical shape, a support tool 26 that supports the buffer body 25, and a receiving metal member 27 that is disposed at the protruding end of the buffer body 25 and receives the end metal fitting 9. The opening shock of the door 1 can be transmitted in a state of being evenly distributed to the buffer body 25 by the receiving metal fitting 27 and further can be received evenly by the support 26, so that the compression deformation of the buffer body 25 when receiving the shock The variation of the aspect can be eliminated, and the shock absorbing and absorbing action can always be exhibited in a stable state. Variations in the shock absorbing and absorbing action based on the difference between the individual shock absorbers 11 can be eliminated.

  The bracket 13 is formed by the fastening wall 14, the pair of left and right side walls 15, and the front wall 16 that connects both side walls 15, and the three members of the receiving bracket 27, the buffer body 25, and the support 26 are arranged between the pair of left and right side walls 15. The shock absorber 11 that receives and holds the support 26 on one side wall 15 supports the side wall 15 on the support 26 side by both the fastening wall 14 and the front wall 16 and has a structural strength. Therefore, the deformation and breakage of the side wall 15 due to impact can be reliably prevented as compared with the case where the support tool 26 is held by the cantilever side wall having the same wall thickness. There is also an advantage that the wall thickness of the side wall 15 can be reduced as much as the structural strength can be improved.

  A base block 31 that receives one end of the buffer body 25 and a guide cylinder 32 that supports the buffer body 25 constitute a support 26, and a receiving metal fitting 27 is provided in the guide hole 21 provided in one side wall 15, and the previous guide. According to the shock absorber 11 slidably guided and supported by the cylinder 32, the three bodies of the buffer body 25, the support tool 26, and the receiving bracket 27 can be positioned concentrically. Therefore, the shock of opening the door 1 is accurately and evenly transmitted from the metal fitting 27 to the shock absorber 25, and the shock absorber 25 is evenly received by the support 26, and the shock of shock is accurately and effectively received by the shock absorber 25. Can absorb relaxation.

Example 1 FIGS. 1 to 5 show Example 1 of a tilt stopper according to the present 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. In order to restrict the opening of the door 1 in a state where the door 1 is opened approximately 90 degrees from the closed position, a tilt stopper having a wire 5 as a regulating element is provided between the door 1 and the door frame 2. The tilt stopper is composed of a wire holding body 6 fixed to the door 1, a wire holding body 7 fixed to the door frame 2, a wire 5 connecting both the wire holding bodies 6 and 7, and the like. The wire 5 is made of a stranded wire, and a spherical end fitting 9 is caulked and fixed to the end portion on the door side.

  As shown in FIG. 2, the wire holder 6 on the door 1 side includes an impact absorber 11 that relaxes and absorbs the opening impact of the door 1 transmitted through the end fitting 9, and a bracket 13 that supports the impact absorber 11. Constitute. The bracket 13 has a pair of left and right fastening walls 14, a pair of left and right side walls 15, 15 bent continuously with the fastening wall 14, and an upper and lower surface integrally provided with a front wall 16 that connects both side walls 15, 15. It consists of a press fitting and is made of a stainless steel plate.

  The fastening wall 14 protrudes upward from the upper edges of the side walls 15 and 15 and the front wall 16, and screw insertion holes 17 are provided on the left and right plate surfaces of the protruding portion. Of the left and right side walls 15, the left side wall as viewed in FIG. 3 is subjected to burring so that the positioning seat 19 bulges to the inner surface of the wall, and a bell mouth-shaped flank on the outer surface of the wall. 20 is formed. The right side wall 15 is provided with a guide hole 21 for a receiving bracket 27 described later.

  The shock absorber 11 is mainly composed of a shock absorber 25 formed of low resilience rubber. Specifically, a shock absorber 25 formed in a cylindrical shape using low-resilience rubber, a support 26 attached to the bracket 13 to support the shock absorber 25, and an end fitting disposed at the protruding end of the shock absorber 25. The shock absorber 11 is composed of a receiving metal 27 that receives 9. Examples of the low resilience rubber include commercially available honey night (registered trademark) of Inner and Outer Rubber Industrial Co., Ltd. and low resilience foam made of urethane resin having a resilience of 15% or less (JIS K 6400-3). Although applicable, the former low-resilience rubber is preferred.

  The shock absorber 25 is formed as a single injection-molded cylindrical block, and an insertion hole 29 for passing the wire 5 is formed therein. The support 26 includes a base block 31 that receives one end of the buffer body 25 and a guide cylinder 32 that supports the buffer body 25. The base block 31 is made of a cylindrically-turned product having a recess 33 that fits outside the positioning seat 19 and a through-hole 34 that is continuous with the inner end of the flank 20. The guide cylinder 32 is made of a tube material having an inner diameter dimension slightly larger than the diameter of the wire 5, and is integrated with the base block 31 by screwing one end of the guide cylinder 32 into the previous through hole 34.

  The receiving bracket 27 is a turning product that integrally includes a flange wall 36 that receives the end face of the shock absorber 25 and a cylinder shaft 37 that receives the end fitting 9, and has a diameter slightly larger than that of the guide cylinder 32 along the axis. The through hole 38 is formed in a penetrating manner. The three members, the buffer body 25, the support tool 26, and the metal fitting 27, are assembled to the bracket 13 in the following manner. First, the cylindrical shaft 37 of the metal fitting 27 is inserted into the guide hole 21 from the inner surface side of the right side wall 15. Next, after the buffer body 25 is externally fitted to the guide cylinder 32, the protruding end of the guide cylinder 32 is inserted into the through hole 38 of the receiving metal fitting 27, and the base body block 31 is attached to the left side wall 15 while compressing the buffer body 25. The shock absorber 11 is completed by fitting the concave portion 33 into the positioning seat 19 and placing it on the inner surface.

  As described above, in the state in which the shock absorber 25, the support tool 26, and the metal fitting 27 are assembled in the bracket 13, the support tool 26 and the metal fitting 27 are received and held by the left and right side walls as shown in FIG. The metal fitting 27 is guided and supported by the guide hole 21 and the guide tube 32 so as to be slidable. The buffer body 25 is in a free state or is slightly compressed and deformed.

  As shown in FIG. 4, the wire holder 7 on the door frame 2 side includes a ball chuck 41 for supplementarily fixing the free end of the wire 5, a bending relaxation tool 12 for preventing the wire 5 from being bent into a square shape, and a ball The chuck 41 and the bracket 42 that supports the bending relaxation tool 12 are configured.

  The ball chuck 41 includes a case body 45 having a tapered wall 44 formed on the inner surface, a ball holder 47 that is inserted into the case body 45 to hold three steel balls 46, and the ball holder 47 is tapered. A compression coil spring 48 that presses and urges toward the wall 44 and a spring receiver 49 that is screwed onto the inner surface of the case body 45 are included. The ball holder 47 is integrally provided with an operation shaft 50 for releasing the clamp of the ball 46, and the protruding end portion of the operation shaft 50 protrudes from the spring receiver 49 side to the outside of the case. A screw hole 51 is formed in the case end wall adjacent to the small diameter end of the taper wall 44.

  The bracket 42 is formed of an L-shaped press fitting made of a stainless steel plate material, which is formed by bending a support arm 55 at one end of the fastening seat 54 in an orthogonal shape. The support arm 55 is formed with a screw hole 56 for the bending alleviator 12, and the nominal diameter and screw pitch of the screw hole 56 are the nominal diameter and screw pitch of the screw hole 51 provided in the case body 45. Is consistent with

  The bending relaxation device 12 is formed of a closely wound coil spring, and integrally includes a support arm 55 of the bracket 42 and a screw shaft portion 58 screwed and connected to the case body 45 and a bent portion 59 having a smaller diameter than the screw shaft portion 58. In preparation. The adjacent pitch of the strands in the screw shaft portion 58 is matched with the screw pitch of the previous screw holes 51 and 55. The bent portion 59 is set to have an inner diameter dimension such that the inner surface thereof is in close contact with the peripheral surface of the wire 5. After the screw shaft portion 58 is screwed into the screw hole 51 of the case body 45 and the bending relaxation device 12 is integrated with the case body 45, the bent portion 59 is inserted into the screw hole 55 of the support arm 55, and further the screw shaft portion. By screwing 58 into the screw hole 55, the ball chuck 41 and the bending relaxation tool 12 can be integrated with the bracket 42.

  As shown in FIGS. 1 and 4, the wire holder 7 is attached to the door frame by attaching the fastening seat 54 to the upper arm of the door frame 2 and fastening the bracket 42 with the screws 60 in a state where the support arm 55 faces downward. 2 is fixed. Further, as shown in FIG. 1, the wire holding body 6 on the door 1 side is fixed to the door 1 by placing the fastening wall 14 on the inner wall or door bar of the door 1 and fastening the bracket 13 with screws 61. In this state, the free end of the wire 5 is inserted into the shock absorber 11 and the bracket 13 from the side of the metal fitting 27, and further inserted into the bending relaxation tool 12 and the ball chuck 41, so that the tension length of the wire 5 is adjusted appropriately. By doing so, the opening limit of the door 1 can be set to an arbitrary amount within the entire length of the wire 5. Note that the wire 5 may be inserted into the wire holders 6 and 7 in advance, and the wire holders 6 and 7 may be fastened to the door 1 and the door frame 2.

  Next, the buffering action of the shock absorber 11 will be mainly described. In many cases, the wire 5 in the door-closed state is bent in a U shape with its midway part hanging down by its own weight. When the closed door 1 is about to open, the door 1 may be swung open and swung to the limit position due to wind. In that case, the loosened wire 5 is pulled by the door 1 to connect the wire holders 6 and 7 at the shortest distance. At this time, the end fitting 9 fixed to the end portion of the wire 5 is pulled by the wire 5 and comes into contact with the protruding end of the receiving fitting 27, and the shock absorber 25 is impacted toward the base block 31 via the receiving fitting 27. Push on.

  The shock absorber 25 which has received the opening shock of the door 1 is elastically deformed in the compressing direction, and the inner and outer peripheral surfaces of the shock absorber 25 swell as shown by an imaginary line in FIG. . Most of the impact energy absorbed by the buffer body 25 due to elastic deformation is released as thermal energy. As a result, it is possible to prevent an excessive impact load from acting on the wire 5, and thus it is possible to reliably prevent the wire 5 from being cut or stretched and deformed due to excessive tension. It is possible to eliminate the deformation of the door wall surface to which the bracket 13 is fastened. Furthermore, since the side wall 15 on which the base block 31 is supported is supported at both ends by the fastening wall 14 and the front wall 16, the side wall 15 is not deformed by receiving an impact. In addition, the swelling of the front and rear peripheral surfaces when the buffer body 25 is compressively deformed is regulated by the fastening wall 14 and the front wall 16 (see FIG. 5).

  When the door 1 is winded and swings suddenly to the open limit position, the wire lead-out portion on the bracket 13 side is gently curved along the bell mouth shape of the flank 20 as shown in FIG. Further, as shown in FIG. 1, the wire lead-out portion on the ball chuck 41 side is bent and deformed to absorb the impact, and at the same time, the elastic force of the bending relaxer 12 repels the bending of the wire 5. It is possible to prevent the wire 5 from being bent into a square shape at each wire lead-out portion.

  For example, when the shock absorber 25 is formed of a compression coil spring, it is inevitable that the door 1 that is suddenly opened is suddenly closed by the reaction of the compressed spring. However, the shock absorber 25 formed of low-rebound rubber hardly repels while being compressed and deformed under impact. Therefore, the door closing operation due to the reaction of the buffer 25 can be wiped out, and the door 1 can be closed safely and as the user intends. After the compression-deformed buffer body 25 is released from the tensile force acting on the wire 1, it gradually returns to the outer shape in the free state and restores to the standby state shown in FIG.

(Example 2) FIG.6 and FIG.7 shows the modification of the wire holder 6 by the side of the door 1. FIG. In this case, the bracket 13 is formed of a rectangular flat plate, and the shock absorber 11 is disposed on the side facing the door wall surface. In the first embodiment, the guide cylinder 32 of the support 26 and the cylinder shaft 37 of the metal fitting 27 are omitted, and the bending relaxation tool 12 is added to the wire lead-out portion.

  The upper half of the bracket 13 functions as a fastening wall 14 having screw insertion holes 17, and a positioning seat 19 and a flank 20 are formed at the left and right center of the lower half side plate surface. Screw holes 19a and 31a for screwing the bending relaxation tool 12 are formed in the inner surface of the positioning seat 19 and the inner surface of the base block 31 constituting the support tool 26, respectively. The bending relaxation tool 12 is the same as the bending relaxation tool 12 described in the first embodiment. Although the buffer body 25 is formed in a cylindrical shape, an insertion hole 29 having a diameter slightly larger than that of the wire 5 is formed on the inner surface along the axis. The receiving metal fitting 27 is formed in a disk shape, and a tapered surface-like seating surface 64 for receiving the end metal fitting 9 is formed on the side facing the door wall surface. The buffer body 25 is bonded and fixed to the end face of the base block 31 and the end face of the receiving metal fitting 27, respectively. The other parts are the same as those in the first embodiment, and therefore, the same members are denoted by the same reference numerals and the description thereof is omitted. The same applies to the following embodiments.

  According to the wire holder 6 configured as described above, similarly to the tilt stopper of the first embodiment, the shock-absorbing body 25 is compressed and deformed so that the opening shock of the door 1 can be relaxed and absorbed, and the door closing operation due to the reaction is also performed. Can be prevented. Further, the bending relaxation tool 12 can prevent the wire 5 from being bent into a square shape at the wire lead-out portion. Also in the bracket 13 of the first embodiment, the bending relaxation tool 12 can be additionally attached to the wire lead-out portion as in this embodiment.

(Example 3) FIG. 8 and FIG. 9 show another modification of the wire holder 6 on the door 1 side. There, the bracket 13 was formed in a cross-sectional L shape with a fastening seat 66 and a support arm 67 in the same manner as the bracket 42 on the door frame 2 side in Example 1, and the overall vertical width was enlarged. In addition, a pair of left and right screw insertion holes 17 were formed above and below the plate surface of the fastening seat 66, and a positioning seat 19 and a clearance surface 20 were formed above and below the support arm 67. The shock absorber 11 is formed in the same manner as in Example 2, but the overall length of the buffer 25 is set larger than that of the buffer 25 in Example 2. According to the wire holder 6 of this embodiment, the bracket 13 is turned upside down and attached to the door 1 so that the wire holder 6 can be applied to either the right opening door or the left opening door. Since it is possible to cope with a mistake, it is possible to save the entire cost of the tilt stopper as compared with the case where the left-dedicated bracket 13 and the right-dedicated bracket 13 are provided. There is no need to change the fastening position of the bracket 13 with respect to the door 1.

(Example 4) FIG. 10 and FIG. 11 show another modification of the wire holder 6 on the door 1 side. There, the shock absorber 11 is composed of three buffer bodies 25, a support 26 and a metal fitting 27 that sandwich both ends of the buffer bodies 25. A guide cylinder 32 is integrally formed on the support 26, and a slide cylinder 66 that is externally fitted to the guide cylinder 32 is integrally formed on the metal fitting 27. Moreover, the buffer body 25 was formed in the cross-sectional fan shape. Thus, the shock absorber 11 can be configured to include a plurality of buffer bodies 25, and the cross-sectional shape of the buffer body 25 can be changed to an arbitrary shape as necessary.

  The tilt stopper of the present invention can be implemented in the following form. A wire holding body 6 fixed to the door 1, a wire holding body 7 fixed to the door frame 2, and a wire 5 that connects both the wire holding bodies 6, 7 to regulate the opening limit of the door 1 are provided. The end fitting 9 fixed to the end of the wire 5 is provided with a shock absorber 11 for relaxing and absorbing the opening shock of the door 1, and the shock absorber 11 is mainly composed of a buffer 25 made of low-rebound rubber. This is a tilt stop.

  The wire holder 7 fixed to the door frame 2 side does not need to be configured to include the ball chuck 41. For example, the wire holder 6 in the first embodiment is fixed to both the door 1 side and the door frame 2 side. It can be used as a tilt stop. In that case, an impact force that acts on the wire 5 can be more effectively mitigated and absorbed by the buffer body 25 of the wire holding body 6 provided on both the door 1 side and the door frame 2 side. However, since the tension length of the wire 5 cannot be changed, the opening limit of the door 1 cannot be changed. The wire holder 7 including the ball chuck 41 may be fixed to the door 1 side, and the wire holder 6 including the shock absorber 11 may be provided on the door frame 2 side.

  Other than the above embodiment, the end fitting 9 does not need to be formed in a spherical shape, and can be formed in a short shaft shape or a rectangular parallelepiped shape. The shock absorber 11 can be composed of the shock absorber 25 and the support 26 or the shock absorber 25 and the receiving metal fitting 27 to simplify the structure. If necessary, the end fitting 9 can be directly received by the buffer body 25 and the impact of the wire 5 can be relaxed and absorbed. The buffer body 25 need not have a cylindrical structure. For example, the buffer body 25 may be formed into a round shaft or each shaft shape, and a groove reaching the shaft center from the shaft peripheral surface may be formed from one end to the other end, and this may be used as the insertion hole 29. Furthermore, a low resilience rubber sheet can be wound into a spiral shape to form the buffer body 25.

  The shock absorber 11 or the buffer body 25 can be integrated with the end fitting 9. In that case, the bracket 13 is simply fixed to the door 1, the shock absorber 11 or the buffer body 25 contacts the bracket 13 together with the end fitting 9, and the shock acting on the wire 5 is applied by the buffer body 25. Can relax and absorb.
