Abstract

Disclosed is a moving apparatus that attenuates the velocity of a moving body. When a sliding door equipped with a moving apparatus (16) is moved in the closing direction (direction of arrow A) and a rod (74) in a latch unit (28) is pressed by a pin member (52) arranged on a door frame, holding members (64) are closed and holding parts (70) are moved toward each other to hold the pin member (52). Thus, the state in which locking pieces (78) are locked with the tip of a rail (26) is released, and the latch unit (28) is moved toward a latch unit (30) by the energizing force of a tension spring (48). The latch unit (28) therefore draws the sliding door in the closing direction via the pin member (52). Because a piston rod (44) is connected to the latch unit (28) here, the piston rod (44) is pressed into a cylinder (42) by the movement of the latch unit (28).

The catcher is held at the standby position against the urging force of the urging mechanism that urges the moving body toward the closing direction or the opening direction.

When the catcher engages with the striker by moving the moving body in the closing direction, the holding state of the catcher in the standby position is released, and the moving body is automatically moved to the stop position via the catcher by the urging force of the urging mechanism. To move to.

In Patent Document 2, a first moving member and a second moving member are slidably provided on a case attached to the main body, and the first moving member and the second moving member are associated with the case. Each latch which can be stopped is rotatably provided. Further, an urging mechanism is provided between the first moving member and the second moving member, and urges the respective latches in a direction to approach each other.

The pin member provided on the moving body engages with the latch, and the engagement state with the case is released, so that the moving body is moved through the first moving member by the urging force of the urging mechanism. The moving body moves to the first moving member side through the second moving member. Thus, the sliding door is automatically moved when the sliding door is closed and opened.

BEST MODE FOR CARRYING OUT THE INVENTION

Next, a moving device for a moving body according to an embodiment of the present invention will be described.
1A and 1B show a sliding door 10 as a moving body, which can be moved horizontally along rails (not shown) provided above and below a door frame 12 as a frame. By the movement of the sliding door 10, the opening 14 in the door frame 12 is closed or opened. Here, a moving device 16 is provided at the center of the upper end of the sliding door 10.

(Configuration of mobile device)
Here, the configuration of the mobile device will be described.
As shown in FIGS. 2 and 3, the moving device 16 includes a substantially box-shaped case 18. At both ends in the longitudinal direction of the case 18, mounting

portions

20 and 22 are provided at the lower portion in the height direction of the case 18, and a fixing screw (not shown) can be inserted into the center of the mounting

portions

20 and 22.

Insertion holes

20A and 22A are respectively formed.

The case 18 is accommodated in an accommodation hole 24 (see FIG. 1) provided in the upper end surface of the sliding door 10 (see FIG. 1), a fixing screw is inserted into the

insertion holes

20A and 22A, and a fixing screw is attached to the bottom of the accommodation hole 24. The screwed case 18 is fixed to the sliding door 10.

Further, a pair of rails 26 are provided on the inner wall surface of the case 18 along the longitudinal direction of the case 18 at the center in the height direction of the case 18. On the rail 26,

latch units

28 and 30 are placed at both ends of the case 18 in the longitudinal direction.

The

latch units

28 and 30 include

sliders

36 and 38 that slide along the rail 26 in the case 18, and a latch case (holding mechanism) 66 provided at the end of the

sliders

36 and 38. Yes.

In addition, at the lower part of the

sliders

36 and 38, retaining

pieces

32 and 34 that are exposed from the lower part of the rail 26 and are located at the lower part in the height direction of the case 18 and prevent the

sliders

36 and 38 from being detached are provided, respectively. The rail 26 can be clamped between the

sliders

36 and 38 and the retaining

pieces

32 and 34. When the

latch units

28 and 30 move in the case 18, the

latch units

28 and 30 are prevented from rattling by moving in the case 18 via the

sliders

36 and 38.

Further, a damper (attenuating mechanism) 40 is provided between the slider 36 and the slider 38. The damper 40 includes a cylinder 42, and the cylinder 42 is filled with a viscous fluid. Further, a piston (not shown) is provided in the cylinder 42 so that the cylinder 42 can reciprocate. The piston compresses the volume of the viscous fluid so that a damping force acts on the piston rod 44 provided on the piston.

The piston rod 44 is connected to the slider 36, and the cylinder 42 is connected to the slider 38. When the slider 36 (latch unit 28) or the slider 38 (latch unit 30) moves, the moving speed is attenuated.

Here, the damper 40 including the cylinder 42 and the piston is taken as an example, but it is only necessary to be able to attenuate the moving speed of the slider 36 (latch unit 28) or the slider 38 (latch unit 30). The damper is not particularly limited. For example, a damper including a rack and a damper gear may be used.

On the other hand, a connecting portion 46 is provided below the retaining piece 32 on the latch unit 28 side, and one end of a tension spring (biasing mechanism) 48 is connected. A connecting portion 50 is provided on the attachment portion 22 side of the case 18, and the other end portion of the tension spring 48 is connected to the connecting portion 50.

Then, in a state where the latch unit 28 is disposed on the mounting portion 20 side of the case 18 (see FIG. 3), the tension spring 48 is in a state where elastic energy (biasing force) is accumulated. For this reason, even if the damping force by the damper 40 acts on the latch unit 28, the sliding door 10 (described later) is pulled to the end by the elastic energy accumulated in the tension spring 48.

By the way, both ends in the longitudinal direction of the case 18 located at the upper part in the height direction of the case 18 are openings, and pin members (strikers) 52 and 54 provided on the door frame 12 are allowed to enter. Yes. A pair of

guide pieces

56 and 58 are respectively provided at both ends in the longitudinal direction of the case 18, and are inclined surfaces that gradually approach each other as they go into the case 18. The

pin members

52 and 54 are reliably guided into the

latch units

28 and 30 by the

guide pieces

56 and 58, respectively.

In addition, rectangular window holes 60 are formed in the upper portion of the case 18 in the height direction so as to be adjacent to the

guide pieces

56, 58. As will be described later, the

latch units

28, 30 are connected to the case 18. Thus, the holding member 64 provided in the

latch units

28 and 30 can be extended outward through the window hole 60 in a state where the movement is restricted (so-called locked state).

Further, a pair of engaging recesses 82 are formed along the longitudinal direction of the case 18 in the center of the upper portion of the case 18 in the height direction, and the surface of the engaging recess 82 extends along the longitudinal direction of the case 18. A plurality of claw portions 84 are provided at predetermined intervals. A cover 86 having a substantially inverted U-shaped cross section can be engaged with the engaging recess 82.

A rectangular hole 88 in which the claw portion 84 is locked is formed on the side wall of the cover 86. The cover 86 is fitted from above the engaging recess 82, and the claw portion 84 is locked in the rectangular hole 88. In this state, the damper 40 is prevented from coming off and the upward lifting of the damper 40 is suppressed. Then, on the upper surface of the cover 86, engagement pieces 90 are provided at both ends in the longitudinal direction, and the engagement pieces 90 engage with rails (not shown) provided on the door frame 12.

(Latch unit)
Here, the

latch units

28 and 30 will be described. Note that the latch unit 28 and the latch unit 30 are only different depending on the presence or absence of the connecting portion 46 provided at the lower part of the retaining piece 32, and the other configurations are the same. Therefore, the latch unit 28 will be described as a representative. .

As shown in FIGS. 2, 4A and 4B, a substantially box-shaped latch case 66 is provided at one end of the slider 36 constituting the latch unit 28 (on the guide piece 56 side of the case 18).

Support portions 68 are provided along the height direction of the latch case 66 at both ends in the width direction, which are located at one end portion of the latch case 66 (the guide piece 56 side of the case 18). The substantially central portion of the holding member 64 is supported by the holding member 64 so that the holding member 64 can swing.

On the other hand, as shown in FIGS. 5A and 5B, the holding member 64 is provided with a holding portion 70 for holding the pin member 52 on one end side, and a cam portion (contacted portion) described later on the other end side. 72 is provided. A rod 74 that penetrates the latch case 66 is provided between the holding member 64 and the holding member 64.

The rod 74 can protrude from the inside of the latch case 66, and is latched by a latch spring (biasing member) 76 provided between the stopper 75 and the latch case 66 formed on the outer peripheral surface of the rod 74. It is urged in the direction to project from.

Further, from the outer peripheral surface of the rod 74, a contact portion 74A that contacts the cam portion 72 of the holding member 64 protrudes. As shown in FIG. 5A, in a state where the holding member 64 is opened, the holding portions 70 are directed away from each other as they go away from the support portion 68. On the other hand, the cam part 72 is moving toward the direction closer to each other as it goes away from the support part 68.

For this reason, as shown in FIG. 5B, when the rod 74 moves in the direction against the urging force of the latch spring 76, the position of the contact portion 74 </ b> A contacting the cam portion 72 is shifted, and the contact portion 74 </ b> A The cam portions 72 are separated from each other as they go to the tip portion. As a result, the holding member 64 rotates around the support portion 68, and the holding portions 70 move toward each other.

That is, the cam portion 72 is provided on the other end side of the holding member 64, and the moving amount of the rod 74 is converted into a rotational force that rotates the holding member 64 so that the holding portion 70 is brought close to the holding member 64. As a result, when the rod 74 is pressed in the axial direction, the holding portion 70 comes close and the pin member 52 is held.

As described above, with reference to the support portion 68 of the holding member 64, the holding portion 70 is provided on one end side of the holding member 64, the cam portion 72 is provided on the other end side of the holding member 64, and the cam is connected via the rod 74. The holding parts 70 are brought close to each other by separating the parts 72 from each other.

That is, since the magnitude of the external force acting on the cam portion 72 can be changed by the movement of the rod 74, the holding force by the holding portion 70 can be changed using the support portion 68 as a fulcrum. That is, the stroke of the rod 74 and the position of the support portion 68 of the holding member 64 are changed so that the distance from the support portion 68 to the holding portion 70 is larger than the distance from the support portion 68 to the portion where the abutting portion 74A hits the cam portion 72. By making the length longer, a large holding force can be obtained with a small force by utilizing the lever principle.

Here, as shown in FIG. 4A, an engaging recess 70A is formed on the upper surface side of the holding portion 70 in a state where the inner surface is hollowed out, and the holding member 64 is closed as shown in FIG. 4B. Thus, a gap is provided between the holding unit 70 and the holding unit 70. The pin member 52 can be engaged in this gap.

On the other hand, on the lower surface side of the holding portion 70, the holding member 64 is closed so that almost no gap is provided. In a state where the pin member 52 is engaged in the holding portion 70, the lower end portion of the holding portion 70 receives the tip portion of the pin member 52, and there is no rattling between the pin member 52 and the holding member 64. I am doing so.

Further, as shown in FIGS. 5A and 5B, the distal end portion of the cam portion 72 is provided with a protruding portion 72A that protrudes outward from each other. On the other hand, as shown in FIGS. 4A and 4B, an insertion hole (hole) 66A is formed in the side wall of the latch case 66, and the protrusion 72A extends to the insertion hole 66A in a state where the holding member 64 is closed. The holding member 64 is prevented from rattling with the holding member 64 holding the pin member 52 inserted.

Incidentally, a locking piece 78 that is exposed from the lower portion of the rail 26 and is positioned at the lower portion in the height direction of the case 18 is provided at the lower portion of the holding member 64. A gap is provided between the rail 26 and the mounting portion 20 (see FIG. 3). As shown in FIG. 4A, the locking piece 78 is locked to the front end portion of the rail 26 with the holding member 64 open. Is done. At this time, the holding member 64 projects outward through the window hole 60.

Here, as shown in FIG. 2, a locking hole 80 is formed in the lower portion of the window hole 60 in the case 18, and the locking piece 78 is locked to the tip end portion of the rail 26. The distal end portion of the stop piece 78 is inserted into the locking hole 80. In this state, the latch unit 28 is locked.

When the pin member 52 comes into contact with the rod 74 of the latch unit 28 and the rod 74 is pressed in the direction against the urging force of the latch spring 76, the holding member 64 is closed as shown in FIG. At this time, the front end of the locking piece 78 comes out of the locking hole 80, and the locking piece 78 is released from the locked state with the front end of the rail 26 (so-called unlocking).

(Operation of moving device of moving body)
Next, the operation of the moving device according to this embodiment will be described.
As shown in FIGS. 1A, 6A and 6B, the sliding door 10 is moved in the closing direction (arrow A direction). 6A is a schematic plan view corresponding to FIG. 1A showing the upper part of the case 18, and FIG. 6B is a schematic cross-sectional view corresponding to FIG.

The guide piece 56 (see FIG. 2) of the moving device 16 passes through the pin member 52, and as shown in FIGS. 5A and 5B, the pin member 52 comes into contact with the rod 74 of the latch unit 28 and the biasing force of the latch spring 76 is obtained. When the rod 74 is pressed in a direction against the above, the cam portions 72 of the holding member 64 are pushed apart by the movement of the contact portion 74A provided on the rod 74 and separated from each other. As a result, the holding member 64 rotates around the support portion 68, the holding member 64 closes, and the holding portions 70 come close to each other and hold the pin member 52.

At this time, the distal end portion of the locking piece 78 shown in FIG. 4A comes out of the locking hole 80 (see FIG. 2), and the locking piece 78 is released from the locked state with the distal end portion of the rail 26 (locked). Released). In a state where the latch unit 28 is locked, as shown in FIG. 6B, since elastic energy (biasing force) by the tension spring 48 is accumulated, when the latch unit 28 is unlocked, the tension spring 48 A biasing force acts.

Since the movement of the latch unit 28 is restricted by the pin member 52, the urging force of the tension spring 48 acts on the case 18 as shown in FIGS. 1B, 7A and 7B. That is, the case 18 moves in the direction of arrow A based on the latch unit 28, and the sliding door 10 moves in the closing direction via the case 18. 7A is a schematic plan view corresponding to FIG. 1B showing the upper part of the case 18, and FIG. 7B is a schematic cross-sectional view corresponding to FIG.

Here, when the case 18 moves in the arrow A direction with reference to the latch unit 28, the piston rod 44 is pushed into the cylinder 42 as shown in FIGS. 6A and 7A. For this reason, the damping force by the damper 40 acts on the case 18. Therefore, the sliding door 10 moves gently in the closing direction. When the sliding door 10 is completely closed, the sliding door 10 comes into contact with the door frame 12, but the impact sound at that time is prevented.

On the other hand, from the state shown in FIGS. 7A and 7B, the sliding door 10 is moved in the opening direction (the direction opposite to the arrow A direction). At this time, the latch unit 28 is moved through the sliding door 10 and the pin member 52. However, since the latch unit 28 is moved in the direction (the arrow A direction) against the urging force of the tension spring 48, the sliding door 10 is moved accordingly. Will receive the load. Thereby, the sliding door 10 is prevented from being opened without darkness.

Further, the piston rod 44 is pulled out from the cylinder 42 by the movement of the latch unit 28. Therefore, a so-called drag force (<damping force) generated when the piston moves in the cylinder 42 acts on the latch unit 28.

Then, when the latch unit 28 is moved via the pin member 52 and the locking piece 78 of the holding member 64 reaches the leading end portion of the rail 26, the locking piece 78 is locked to the leading end portion of the rail 26. The leading end of the piece 78 is inserted into the locking hole 80, and the holding member 64 extends outward through the window hole 60. In this state, the movement of the latch unit 28 is restricted (locked state).

9A, the pin member 52 is disengaged from the holding member 64. In this state, the elastic energy (biasing force) by the tension spring 48 is accumulated as shown in FIG. 9B. It is the state that was done. 9A is a schematic plan view corresponding to FIG. 8A showing the upper part of the case 18, and FIG. 9B is a schematic cross-sectional view corresponding to FIG.

In this state, as shown in FIGS. 8A and 8B, when the sliding door 10 is moved in the opening direction (arrow B direction), the drag by the tension spring 48 and the damper 40 does not act, so the sliding door 10 becomes lighter.

Then, the sliding door 10 is further moved in the opening direction (arrow B direction), the guide piece 58 (see FIG. 2) of the moving device 16 passes through the pin member 54, and as shown in FIGS. 5A and 5B, the pin member 54 Comes into contact with the rod 74 of the latch unit 30 and the rod 74 is pressed in a direction against the urging force of the latch spring 76.

Then, the cam portions 72 of the holding member 64 are pushed apart by the movement of the contact portion 74A provided on the rod 74 and separated from each other. As a result, the holding member 64 rotates around the support portion 68, the holding member 64 closes, and the holding portions 70 come close to each other and hold the pin member 54.

At this time, the distal end portion of the locking piece 78 shown in FIG. 4A comes out of the locking hole 80 (see FIG. 2), and the locking piece 78 is released from the locked state with the distal end portion of the rail 26 (locked). Released). Then, as shown in FIGS. 10A and 11A, the piston rod 44 is pushed into the cylinder 42 by the case 18 moving through the latch unit 30.

Therefore, a damping force by the damper 40 acts on the case 18 via the latch unit 30. 10A is a schematic plan view corresponding to FIG. 8B showing the upper part of the case 18, and FIG. 11A is a schematic plan view corresponding to FIG. 8C showing the upper part of the case 18.

Here, as shown in FIGS. 10B and 11B, since the tension spring 48 is connected to the latch unit 28 and the case 18, even if the latch unit 30 is unlocked, the urging force by the tension spring 48 is not latched. Does not work. 10B is a schematic cross-sectional view corresponding to FIG. 8B showing the lower part of the case 18, and FIG. 11B is a schematic cross-sectional view corresponding to FIG. 8C showing the lower part of the case 18.

As mentioned above, in this embodiment, although the moving apparatus was provided in the sliding door, you may provide a moving apparatus in the door frame side. In this case, a pin member is provided on the sliding door side. Further, in the present embodiment, the single-drawing type sliding door has been described, but it may be applied to a sliding-type sliding door. In this case, two moving devices are required. Furthermore, although the sliding door moved in the horizontal direction has been described here, it may be applied to a sliding door moved in the vertical direction, or the moving device may be applied to drawers and the like.
