  The present invention relates to an assist device for a movable body that assists the operation of the movable body.

  In order to assist the operation of a movable body such as a hanging door, there is known a movable body assist device that uses a biasing mechanism to make a self-running movement. In such an assist device for a movable body, the movable body is suspended and supported by a rail attached to the duck so as to be able to travel via a suspension vehicle. And the receiving body is provided in the head side, the closer is provided in the suspension door side, and the contact body which can be engaged with the receiving body is provided in the housing of the closer.

  The abutting body is slidable in a standby position and a retracted position in the housing, and is connected to a tension coil spring as an urging mechanism. The contact body has an engagement portion at the tip, for example, and this engagement portion can be engaged with and released from the receiving body. In general, one end of a housing is fixed to a movable body via a suspension car, and the suspension car and the housing are movably engaged in a rail. Further, an auxiliary vehicle capable of traveling along the rail is provided at the other end of the housing.

  When the suspension door is in the open position, the contact body is held in the standby position with the tension coil spring extended to the maximum. When the operator moves the suspension door from the open position to the closed position, the abutting body hits the receiving body in the middle, and captures the receiving body. At the same time, the holding of the abutment body in the standby position is released, and the abutment body is pulled by the tension coil spring while moving to the retracted position while capturing the receiving body. For this reason, the suspension door of this moving dimension is forcibly moved.

  When the suspension door is in the closed position, the contact body is in a state where the tension coil spring is compressed. When the operator moves the suspension door from the closed position toward the open position, the suspension door moves while pulling the tension coil spring. When the predetermined position is reached, the contact body opens the receiving body and is held at the standby position again.

The front end portion of the housing 40 is connected to the base 21 of the suspension wheel 20 </ b> A via the connecting portion 26.

  A guide slit 44 is formed in the housing 40, and the latch 30 moves while being guided by the guide slit 44, and can be switched between a standby posture and a retracted posture by rotating and linearly moving. . The guide slit 44 has a main guide 44a along the sliding direction and a standby guide 44b that is bent downward from the main guide 44a.

  A rear end portion of a tension coil spring 51 as an urging means is connected to the rear end portion of the housing 40. Further, an auxiliary roller 48 is rotatably supported at the lower portion of the rear end of the housing 40. The auxiliary roller 48 is disposed so as to be able to travel on the upper surface of the inner protruding portion 10 c of the rail 10, and the rear end of the housing 40 is supported by the auxiliary roller 48 so as to be able to travel with respect to the rail 10.

  The latch 30 includes a latch base 31 that reciprocates in the first direction along the guide slit 44 of the housing 40, and a catcher 32 that is coupled to the front end of the latch base 31 so as to be rotatable about the axis C1. doing.

  The latch base 31 is housed in the upper part of the housing 40 and moves in the sliding direction by the guide slit 44. The front end portion of the tension coil spring 51 is connected to the lower portion of the latch base 31 and is always urged in the retracting direction.

  Further, a piston damper 60 is connected to the rear end surface of the latch base 31 so that the movement of the latch base 31 is braked.

  The catcher 32 is rotatably connected to the latch base 31 and has a hook shape with an upper opening. The catcher 32 is guided by the guide slit 44 together with the latch base 31 to reciprocate between the standby position and the retracted position, and at the standby position, the catcher 32 rotates about the axis C1 along the Y axis with respect to the latch base 31. , Engage or disengage the striker 11.

  The urging mechanism 50 is constituted by a tension coil spring 51, for example. The tension coil spring 51 is arranged in the lower part in the housing 40 so that the axial direction is along the sliding direction. One end of the tension coil spring 51 is connected to the catcher 32, and the other end of the tension coil spring 51 is connected to the housing 40.

  When the movable body M is moved to one side (forward), the tension coil spring 51 pulls the latch 30 that has captured the striker 11 relative to the housing 40 toward the other side (rear side). Is forcibly moved forward with respect to the rail 10 and the Kamoi W.

  The braking mechanism 60 includes a piston damper 60 provided in the upper chamber of the housing 40.

  In the movable body assist device 1 configured as described above, the suspension wheel 20A has a simple configuration in which a restriction portion 26a that protrudes toward the support body W is provided at the end opposite to the connection side of the housing 40. The height of the closer can always be held at an appropriate position by preventing the lifting of the hanging door. Therefore, the dimensional accuracy of the striker 11 and the closer 12 can be set with high accuracy.

  The operation of the movable body assist device 1 will be described with reference to FIG. In the stage before the suspension door M is moved forward to the self-propelled starting position, the catcher 32 is held by the front standby guide 44b and the striker 11 is released, as shown in FIGS. .

  When the suspension door M is moved forward to the self-running start position, the striker 11 enters the housing 40 from the front, is pushed by the striker 11, and the catcher 32 is pushed backward against the bias of the tension coil spring 51. While rotating in the R1 direction in the figure, the striker 11 is captured. At this time, the catcher 32 enters the main guide 44 a from the standby guide 44 b and is slidable with respect to the housing 40. Then, the latch 30 moves to the retracted position behind the housing 40 in a state where the striker 11 is captured by the bias of the tension coil spring 51. Along with this relative movement, the suspension door M self-travels forward to the stop position with respect to the striker 11 and the support W.

  On the other hand, when the movable door M is moved backward from the stop position, when the movable body M is moved, the latch 30 integrated with the striker 11 moves relatively forward while accumulating the tension coil spring 51. Then, when the movable body M reaches the self-running start position, it enters the standby guide 44b of the housing 40, and the catcher 32 rotates in the R2 direction. Thereby, the catcher 32 is returned to the released state, and the latch 30 and the striker 11 are separated. Thereafter, the movement restriction of the movable body M is released.

  According to the movable body assist device 1 according to the present embodiment, it is possible to prevent the jumping up due to the contact between the latch 30 and the striker 11 with a simple configuration by the restricting portion 26a protruding to the support side. . That is, since the clearance between the rail 10 is reduced by the restricting portion 26a, the swinging movement of the closer 12 is restricted, and when the flip-up force is generated by the vertical contact between the latch 30 and the striker 11, When the restricting portion 26a protruding upward interferes with the rail 10, the suspension door M can be prevented from jumping up.

  In addition, since it is a simple structure in which only a protrusion is provided on the closer 12 side and can be applied to various types of hanging doors M and Kamoi W, for example, compared to a structure in which a spacer is provided on the rail 10 side to prevent splashing, It eliminates the trouble of construction work and construction mistakes, and the structure is simple and versatile.

  Furthermore, in this embodiment, a high regulation effect is obtained by providing the regulation part 26a at one end. In addition, since the low frictional resistance portion 26b is configured on the end face, the sliding resistance when contacting the rail 10 can be reduced, and the friction noise can be reduced.

  By forming the opening 26d that opens upward between the restricting portions 26a, it is possible to prevent interference with the striker 11.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation implementation is possible in the range which does not deviate from the summary of this invention. In addition, the specific configuration, material, and the like of each unit are not limited to those illustrated in the above embodiment, and can be changed as appropriate.

  In the above embodiment, the configuration in which the restricting portion 26a is formed on one end side of the connecting portion 26 provided on the base 21 is exemplified, but the present invention is not limited to this. For example, as shown in FIG. 4 as another embodiment, a restricting portion 126 protruding upward may be formed on one end side of the housing 40. Also in this case, when the lifting force is generated by reducing the gap with the rail 10, the swinging of the suspension door M can be restricted to prevent the lifting. Furthermore, the overall length of the suspension wheel 20A and the housing 40 connected in the X direction can be shortened by being provided in the housing 40.

  The position of the restricting portion 26 is not limited to the above embodiment, and for example, a restricting portion that protrudes toward the support body is provided at a portion that is displaced toward the support body during the engagement operation between the contact body and the receiving body. Thus, the effect of preventing the jumping up can be obtained.

  Although illustrated about the case where a nonwoven fabric is provided in an end surface as the low frictional resistance part 26e, it is not restricted to this. For example, it is good also as providing the rotating roller which can drive the rail 10 in the upper end part which is the support body W side of the control part 26a. Also in this case, when the roller abuts against the rail 10, sliding resistance and frictional noise can be reduced.

  Furthermore, it is also possible to provide a raised material or the like instead of the nonwoven fabric as the low friction resistance portion 26e. In this case as well, sliding resistance and frictional noise when contacting the rail 10 can be reduced as in the above embodiment.

  In the above embodiment, the case where the latch 30 is provided only on one side of the housing 40 and the one-way assist operation is performed is illustrated, but the present invention is not limited to this. For example, the latch 30 may be provided at both ends of the housing 40 and the strikers 11 may be provided at both the left and right sides of the rail 10 to assist the operation in both directions on the door end side and the door bottom side. In this case, for example, both ends of the tension coil spring 51 are connected to the latch bases 31 on both sides, and the ends of the cylinder 61 and the piston rod 62 of the piston damper 60 are connected to the latch bases 31 on both sides, respectively. A common mechanism can be used for assisting and braking the latches 30 on both sides.

  In addition, the catcher 32 is shown as a hook-shaped catcher that engages up and down by rotation to capture the striker 11. However, the catcher 32 may have other configurations such as a configuration in which an axial striker is sandwiched between a pair of holding pieces. There may be.

  Furthermore, the present invention can be realized even if some of the constituent features of the above-described embodiment are omitted.
