Description

  The present invention relates to a fixing structure for fixing an object to be fixed such as an assist device for assisting opening / closing of a sliding door to a support such as a sliding door.

  In order to assist the operation of the sliding door, there is known an assist device that includes an urging mechanism and a braking mechanism, and forcibly moves and cushions the sliding door with respect to the door frame. The assist device has a housing, and the urging mechanism and the braking mechanism are accommodated in the housing. Since the housing of this type of assist device is housed in a groove formed in the sliding direction along the sliding direction, it has a long shape in the sliding direction in order to secure a size for housing the biasing mechanism and the braking mechanism. Become. For this reason, in order to stably fix the housing in the groove, both ends in the longitudinal direction of the housing are fixed to the sliding door with screws (see, for example, Patent Document 1).

  However, as described above, in the technique of fixing both ends of the housing to the sliding door with screws, it is necessary to form through holes through which the screws penetrate at both ends of the housing. For this reason, it is necessary to ensure the space which forms the through-hole which a screw passes in the both ends of a housing. As described above, since the urging mechanism and the braking mechanism are accommodated in the housing, it is necessary to enlarge the housing in the longitudinal direction in order to secure a space for forming a through hole through which the screw passes. When the housing is enlarged in the longitudinal direction, the assist device becomes larger than the sliding door, and the assist device may not be fixed to the sliding door.

  On the other hand, as a fixing structure for fixing a door to the sliding door, there is a fixing structure for fixing a mounting frame to the sliding door and accommodating a holding unit for holding the wheel of the door to the mounting frame. In this type of technology, after the door wheel is accommodated in the mounting frame through one of the both ends of the mounting frame, the both ends are closed by a cover (see, for example, Patent Document 2).

Japanese Patent No. 46908446 Japanese Patent No. 2981473

  Like the above-described fixing structure for fixing the housing to the sliding door with a screw, the fixing structure for fixing the object to be fixed to the support using only the screw has the following problems. That is, it is necessary to secure a space for forming a through hole through which a screw passes through the fixed object, and the fixed object becomes large. When the housing of the assist device is used for a fixing structure that fixes the housing to the sliding door, the housing becomes large and the assist device may not be accommodated in the sliding door.

  Moreover, there exists the following problem in the fixing structure using an attachment frame like the above-mentioned fixed structure of a door pulley. That is, since both ends of the mounting frame are covered with the cover, the number of parts increases, resulting in poor work efficiency.

  Then, this invention aims at providing the fixing structure which can improve the efficiency of fixing operation | work while suppressing the enlargement of a to-be-fixed object.

  The fixing structure of the present invention is a fixing structure for fixing an object to be fixed to a support. The fixing structure includes: a holding member that holds a part of the object to be fixed; a first fixing unit that fixes the holding member to the support; and a portion of the object to be fixed that is not held by the holding member. Second fixing means for fixing to a support.

  ADVANTAGE OF THE INVENTION According to this invention, while being able to suppress the enlargement of a to-be-fixed object, the efficiency of fixing work can be improved.

The width direction W is a direction perpendicular to the vertical direction V and the horizontal direction H.

  In this embodiment, the directions used when explaining the first and second assist devices 30 and 80 are fixed to the sliding door 10 assembled to the door frame 20. The direction is based on the state.

  As shown in FIGS. 1-3, the 1st housing 34 is a box type provided with a pair of side wall 38 extended along the horizontal direction H, and the upper end is opening. A partition plate 35 is provided in the first housing 34. The partition plate 35 extends from one side wall 38 toward the other side wall 38 and extends in the horizontal direction H. The partition plate 35 partitions the first housing 34 into an upper upper chamber 36 and a lower lower chamber 37. A latch base 43 is accommodated in the upper chamber 36.

  A slit 40 is formed at one end in the horizontal direction of both side walls 38 of the first housing 34. The slit 40 passes through the side wall 38. The slit 40 includes a main guide path 40a extending along the horizontal direction H to the standby position and the retracted position, and a standby path 40b extending curvedly downward at a standby position on one end side from the main guide path 40a. The main guide path 40a and the standby path 40b are continuous.

  In the lower chamber 37 of the first housing 34, a connecting portion 42 for fixing the end of the tension coil spring 41 to the first housing 34 is formed at the other end. The connecting portion 42 is a shaft-like member that is stretched over both side walls 38, and a tension coil spring 41 is attached to the connecting portion 42.

  The latch 31 is supported by the upper chamber 36 in the first housing 34 so as to be movable along the horizontal direction H. The latch 31 includes a latch base 43 and a rotation portion 44 that is coupled to the tip end portion of the latch base 43 so as to be rotatable around the width direction W.

  The latch base 43 includes a protrusion 43 a that protrudes outward in the width direction and extends in the horizontal direction H. The protrusion 43 a is accommodated in the slit 40 so that the latch 31 can move in the horizontal direction H and engages with the slit 40. When the protrusion 43 a engages with the slit 40, the latch base 43 is slidably held in the horizontal direction H between the pair of side walls 38 that form the upper chamber 36 of the first housing 34.

  A long hole 43 b along the horizontal direction H is formed at the tip of the latch base 43. The rotating portion 44 is engaged with the elongated hole 43b so as to be movable in the horizontal direction H. At the front end portion of the latch base 43, a pressed portion 45 is provided that contacts the striker 25 by the movement of the latch 31 and is pressed in the retracting direction.

  The pressed portion 45 is slidably mounted along the horizontal direction H in the latch base 43 via the coil spring 46. The pressed portion 45 is pulled toward the inside of the latch base 43 along the horizontal direction H by the coil spring 46. A rotating portion 44 is pivotally supported and connected to the lower end portion of the pressed portion 45 so as to be rotatable around the width direction W.

  The rotating portion 44 includes a shaft portion 44 b that has an axial center along the width direction W and protrudes in the width direction W. The shaft portion 44b is inserted into the slit 40 and the long hole 43b, and is engaged so as to be rotatable and movable in the slit 40.

  The rotation part 44 is rotatable about the shaft part 44b in a first rotation direction R1 and a second rotation direction R2 that is opposite to the first rotation direction R1. A catcher 44 a and an engaging portion 44 d are provided at the tip of the rotating portion 44. A biased portion 44 c is provided below the rotating portion 44.

  The catcher 44a has a hook shape that is provided on the distal end side of the rotation portion 44 and protrudes along the first rotation direction R1. The catcher 44a captures the engaging portion 25a of the striker 25 by rotating along the first rotation direction R1. Thus, the latch 31 can be engaged. Specifically, the catcher 44 a is urged in the pulling direction by the pulling force of the coil spring 47 when rotated along the first rotation direction R 1, and the engagement portion 25 a is interposed between the catcher 44 a and the latch base 43. The striker 25 is captured by pinching. Further, the rotation unit 44 releases the striker 25 by releasing the engagement by rotation along the second rotation direction R2.

  Engaging portions 44d are formed on both sides in the width direction of the catcher 44a. The engaging portion 44d protrudes in the width direction W and is movably accommodated in the slit 40. The engaging portion 44d is a prismatic shape having a predetermined shape along the shape of the lower end of the standby path 40b, and is engaged with and held by the standby path 40b.

  The to-be-biased part 44c is provided in the lower part of the rotation part 44, and is located behind the engaging part 44d. The biased portion 44c is disposed in the lower chamber 37 of the first housing 34, and one end of the tension coil spring 41 is connected thereto. The biased portion 44c is always pulled in the retracting direction by the tension coil spring 41.

  The urging mechanism 32 includes a tension coil spring 41. The tension coil spring 41 is disposed in the lower chamber 37 of the first housing 34 such that the axial direction is along the horizontal direction H. One end of the tension coil spring 41 is connected to the biased portion 44 c below the latch 31, and the other end is connected to the connecting portion 42 of the first housing 34. The tension coil spring 41 urges the latch 31 in the standby state in the retracting direction so as to be hooked and held in the standby path 40b, and urges the latch 31 in the main guide path 40a in the retracting direction to forcibly move. And a function of urging the latch 31 in the second rotation direction R2.

  The brake mechanism 33 includes a piston damper 50 provided in the upper chamber 36 of the first housing 34. The piston damper 50 includes a cylinder 51 in which a fluid is sealed, a piston that reciprocates along the horizontal direction H in the cylinder 51, and a piston rod 52 that is connected to the piston. The end of the piston rod 52 is fixed to the first housing 34, and the outer end of the cylinder 51 facing the piston is fixed to the rear end of the latch 31.

  The braking mechanism 33 applies a resistance force against the pushing and pulling operation of the cylinder 51 or the piston rod 52 by causing the fluid stored in the cylinder 51 to act on the piston housed in the cylinder 51. The sliding movement of the latch 31 with respect to the first housing 34 is braked. Note that a viscous fluid such as silicone oil is typically used as the fluid sealed in the cylinder 51, but is not limited thereto, and a gas may be used.

  Next, the operation of the first assist device 30 will be described. As shown in FIG. 1, in the first state S <b> 1 where the sliding door 10 has not reached the striker 25, the latch 31 is held at the standby position at the end of the first housing 34. The latch 31 is held when the engaging portion 44 d is caught by the standby path 40 b and pulled by the tension coil spring 41, and is held at the standby position of the first housing 34.

  When the operator moves the sliding door 10 to change the sliding door 10 from the first state S <b> 1 to the second state S <b> 2, the pressed portion 45 contacts the striker 25. Then, when the striker 25 pushes the pressed portion 45, the catcher 44a rotates in the first rotation direction R1 around the shaft portion 44b. By this rotation, the catcher 44 a of the rotating portion 44 is engaged with the striker 25, and is thus captured by the striker 25 latch 31.

  When the rotating portion 44 rotates in the first rotating direction R1, the lower engaging portion 44d moves upward and enters the main guide path 40a, and therefore, the standby path 40b of the engaging portion 44d. The holding inside is released. As a result, the latch 31 becomes movable along the main guide path 40a.

  Then, due to the restoring force of the tension coil spring 41, the latch 31 is relatively moved to the right with respect to the first housing 34 and the sliding door 10 and is relatively moved to the retracted position. With this movement, the sliding door 10 and the first housing 34 are forcibly moved relative to the left side with respect to the door frame 20 and the striker 25. At this time, a resistance force is applied by the braking mechanism 33, and the sliding door 10 moves slowly and automatically in a closing direction while buffering.

  Next, an operation when moving the sliding door 10 to change from the second state S2 to the first state S1 will be described. When the sliding door 10 is moved from the second state S 2 to the first state S 1, the latch 31 captures the striker 25 against the biasing force of the tension coil spring 41 and moves to the sliding door 10 and the first housing 34. The sliding door 10 moves to the right side while relatively moving to the left side. Since the latch 31 is connected to the piston rod 52 of the piston damper 50, the latch 31 receives the resistance force of the fluid in the cylinder 51 while moving the piston.

  When the predetermined position is reached, the striker 25 is separated from the pressed portion 45. The catcher 44a rotates in the second rotation direction R2 about the shaft 44b by the restoring force of the tension coil spring 41. By this rotation, the engagement of the catcher 44a with the striker 25 is released. At the same time, the engaging portion 44d is in the standby position at the front end of the main guide path 40a, or the engaging portion 44d enters the lower standby path 40b and is again held in the standby position by the tension coil spring 41. The subsequent movement of the sliding door 10 is released from the urging force of the tension coil spring 41.

  Next, a structure for fixing the first housing 34 in the groove 11 will be described. As shown in FIG. 1, the first housing 34 has one end 34 a and the other end 34 b fixed to the groove 11 of the sliding door 10. Specifically, one end portion 34 a of the first housing 34 is fixed to one end portion of the opening ends along the horizontal direction H of the groove 11 by a screw 60. A through hole 62 through which the screw 60 passes in the vertical direction V is formed in one end 34 a of the first housing 34. A screw hole 63 extending in the vertical direction V is formed in the bottom wall portion 13 of the groove 11. A female screw is formed on the inner surface of the screw hole 63. The screw 60 passes through the through hole 62 from above and is screwed into the screw hole 63 of the groove 11, whereby the one end 34 a of the first housing 34 is fixed to the groove 11.

  The other end 34b of the first housing 34 is fixed to the sliding door 10 via a bracket 70 described later. The fixing structure using the bracket 70 will be specifically described later.

  Next, the second assist device 80 will be described. The second assist device 80 is located on the right side with respect to the first assist device 30 in the groove 11. The second assist device 80 is different from the first assist device 30 in that the second assist device 80 includes a second housing 81 instead of the first housing 34 and a door wheel 82. The second assist device 80 is the same in structure as the first assist device 30 except for the second housing 81 and the door wheel 82.

  Similarly to the assist of the first assist device 30 when the sliding door 10 changes from the first state S1 to the second state S2, the second assisting device 80 moves the sliding door 10 from the first state S1 to the third state. Assist when the state S3 is reached. In addition, about the 2nd assist apparatus 80, the 2nd housing 81 and the doorwheel 82 are demonstrated. Since the other structure of the second assist device 80 is the same as that of the first assist device 30, the same reference numerals are given and description thereof is omitted.
