The present invention provides a moving device for damping the speed of the moving object.

In the first aspect of the present invention, the case is attached to a moving body moving in a frame, two sliders slidably accommodated in the case, and are provided on the slider and away from a striker provided on the frame. Locking the slider to the end of the case, and holding the striker, a gripping mechanism for releasing the locked state of the slider and the end of the case, and attached between the slider to attenuate the speed at which the slider is folded Provided is a moving device having a damping mechanism and a gripping mechanism having one end connected to one slider and the other end connected to the case to hold one slider on the other slider side.

In the above aspect, a case is attached to a movable body moving in the frame, and two cases are accommodated in the case so that the inside of the case can slide. A striker is provided in the frame, and when away from the striker, the gripping mechanism provided on the slider locks the slider to the end of the case, and when the gripping mechanism grips the striker, the locked state of the slider and the end of the case is released.

In addition, a damping mechanism is provided between the sliders to attenuate the speed at which the slider is folded. One slider is connected to one end of the cage mechanism, the other end of the cage mechanism is connected to the case, and one slider is attached to the other slider side. Doing.

Thereby, for example, when the moving body is moved in the closing direction and one holding mechanism is engaged with the striker, the one slider is unlocked and movable. Here, since one slider is supported on the other slider side by the holding mechanism, when one lock is released, one slider tries to move to the other slider side.

However, since one slider is holding the striker, the movable body moves in the closing direction through the striker, one slider and the case. Since a damping mechanism is provided between one slider and the other slider, the movement speed is attenuated when one slider moves. For this reason, when the moving speed of the case moving with respect to one slider is attenuated and the movable body is completely closed, the impact sound by the contact of a movable body and a frame is prevented.

According to a second aspect of the present invention, in the first aspect of the present invention, the gripping mechanism includes a pair of gripping members in which a gripping portion capable of gripping the striker is provided, a support portion for foldably supporting the gripping portion, and A rod formed in the gripping member and provided on the opposite side of the gripping portion on the basis of the support portion, a rod movably disposed between the pair of gripping portions and the abutting portion, and the rod The support member, which is supported on the side of the branch, protrudes from the outer circumferential surface of the rod to abut the contact portion, and when the rod moves in a direction that resists the force of the finger member, the contact portion is moved in a direction away from each other. It may be configured to include a contact portion to move in the direction to close the holding portion.

In the above configuration, the gripping mechanism is provided with a pair of gripping members in which a gripping portion capable of gripping the striker is formed. The holding member is supported by the support part, and makes the support part foldable. The holding member is provided with a contact portion on the opposite side of the holding portion on the basis of the supporting portion, and a rod is formed to be movable between the pair of holding portions and the contact portion.

The rod is held on the gripping portion side by a holding mechanism. Moreover, when the contact part which abuts on the to-be-contacted part protrudes from the outer peripheral surface of the rod, and the rod moves to the direction which resists the holding force of a finger member, the direction to which a to-be-contacted part is moved to mutually spaced apart and the grip part will approach | abut The striker is gripped by the gripper.

Here, the holding portions are formed on one end side of the holding member on the basis of the supporting portion, the contacting portions are formed on the other end side of the holding member, and the holding portions are brought close to each other by separating the contacting portions through the rod. Thereby, since the magnitude | size of the external force acting on a to-be-contacted part can be changed by the movement of a rod, the external force which makes a support part a point, and spaced apart from each other to a to-be-contacted part can be converted into the holding force by a holding part.

In other words, by changing the stroke of the rod and the position of the support of the gripping member, a large gripping force can be obtained with a small force using the principle of lever.

The opening 14 in the door frame 12 is closed or opened by the movement of the sliding door 10. Here, the moving device 16 is provided in the center of the upper end part of the sliding door 10. As shown in FIG.

(Configuration of mobile device)

Here, the configuration of the mobile device will be described.

As shown in FIG. 2 and FIG. 3, the moving device 16 is provided with the substantially case-shaped case 18. As shown in FIG. Attaching parts 20 and 22 are formed at both ends of the case 18 in the longitudinal direction, and a fixing screw (not shown) is inserted into the center part of the attaching parts 20 and 22. Possible insertion holes 20A and 22A are formed, respectively.

The case 18 is accommodated in the accommodation hole 24 (see FIG. 1) formed in the upper surface of the sliding door 10 (see FIG. 1), the fixing screw is inserted into the insertion holes 20A and 22A, and the accommodation hole ( Fix the case 18 to the sliding door 10 by tightening the fixing screw in the bottom of 24).

Moreover, a pair of rails 26 are provided in the center part of the height direction of the case 18 along the longitudinal direction of the case 18 in the inner wall surface of the case 18. As shown in FIG. The rails 26 are provided with latch units 28 and 30 disposed at both ends in the longitudinal direction of the case 18.

The latch units 28 and 30 are provided with sliders 36 and 38 which slide in the case 18 along the rails 26, and latch cases (gripping mechanisms) 66 formed at the ends of the sliders 36 and 38. As shown in FIG. It is configured to include.

In addition, the lower portions of the sliders 36 and 38 are exposed through the lower portions of the rails 26 and are located in the lower portion of the case 18 in the height direction to prevent the falling of the sliders 36 and 38. 34 are formed, respectively, and the rail 26 can be pinched | interposed between the sliders 36 and 38 and the fall prevention pieces 32 and 34. FIG. When the latch units 28 and 30 move in the case 18, the latch units 28 and 30 are not shaken by moving the case 18 through the sliders 36 and 38.

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

The piston rod 44 is connected to the slider 36, and the cylinder 42 is connected to the slider 38, so that the slider 36 (latch unit 28) or the slider 38 (latch unit 30) The movement speed is attenuated during the movement of.

In addition, although the damper 40 comprised from the cylinder 42 and the piston was mentioned here as an example, the moving speed of the slider 36 (latch unit 28) or the slider 38 (latch unit 30) is changed. The damper is not particularly limited because it can be attenuated. For example, the damper may include a rack and a damper gear.

On the other hand, the connection part 46 is formed in the lower part of the fall prevention piece 32 by the latch unit 28 side, and the one end part of the tension spring (cartage mechanism) 48 is connected. The connection part 50 is formed in the attachment part 22 side of the case 18, and the other end part of the tension spring 48 is connected to this connection part 50. As shown in FIG.

In the state where the latch unit 28 is arranged on the attaching part 20 side of the case 18 (see FIG. 3), the elastic spring (charging force) is stored in the tension spring 48. For this reason, even when the damping force by the damper 40 acts on the latch unit 28, the sliding door 10 (to be described later) is attracted to the end by the elastic energy accumulated in the tension spring 48.

By the way, the both ends of the longitudinal direction of the case 18 located in the upper direction of the height direction of the case 18 are open, and the pin members (strikers) 52 and 54 formed in the door frame 12 are accessible. . A pair of guide pieces 56 and 58 are formed in the both ends of the case 18 in the longitudinal direction, respectively, and are inclined surfaces which gradually approach each other as they go into the case 18. The guide pieces 56 and 58 allow the pin members 52 and 54 to be reliably guided into the latch units 28 and 30, respectively.

In the upper portion of the case 18 in the height direction, rectangular window holes 60 are formed adjacent to the guide pieces 56 and 58, respectively, which will be described later. However, the latch units 28 and 30 are provided in the case 18. In a state where movement is restricted (so-called locked state), the gripping member 64 provided in the latch units 28 and 30 is protruded outward through the window hole 60.

Moreover, a pair of engagement recesses 82 are formed in the upper center of the height direction of the case 18 along the longitudinal direction of the case 18, and the case 18 is formed on the surface of the engagement recesses 82. A plurality of protrusions 84 are formed at predetermined intervals along the longitudinal direction of the cross-section. In this engagement recessed part 82, the cover 86 which has a substantially inverted U-shaped cross section is able to be engaged.

The side wall of the cover 86 is formed with a rectangular hole 88 into which the projection 84 is engaged, and the cover 86 is inserted into the rectangular hole 88 by fitting the cover 86 from above the engaging recess 82. The protrusion 84 is caught. In this state, the damper 40 is prevented from being pulled out and lifted upward of the damper 40 is suppressed. And the engaging piece 90 is formed in the both ends of the longitudinal direction in the upper surface of the cover 86, and this engaging piece 90 is engaged with the rail (not shown) provided in the door frame 12. As shown in FIG.

(Latch unit)

Here, the latch units 28 and 30 will be described. In addition, the latch unit 28 and the latch unit 30 is only a difference due to the presence or absence of the connecting portion 46 formed on the lower portion of the release preventing piece 32, and since the other configurations are the same, the latch unit 28 is representative. Explain.

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

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

On the other hand, as shown in Figs. 5A and 5B, the gripping member 64 has a gripping portion 70 for gripping the pin member 52 at one end thereof, and a cam portion (butted portion) described later on the other end ( 72 is formed. In addition, a rod 74 penetrating the latch case 66 is provided between the gripping member 64 and the gripping member 64.

The rod 74 is protruded from the inside of the latch case 66, and the latch spring (cartage member) 76 provided between the stopper 75 formed on the outer circumferential surface of the rod 74 and the latch case 66 is provided. It is touched by the direction which protrudes from the latch case 66 by this.

Moreover, the contact part 74A which abuts on the cam part 72 of the holding member 64 protrudes from the outer peripheral surface of the rod 74. As shown in FIG. As shown in FIG. 5A, in the state in which the holding member 64 is opened, the holding | gripping part 70 faces in the direction which mutually separates as it goes to the direction which separates from the support part 68. As shown in FIG. On the other hand, the cam portion 72 faces in a direction close to each other as it goes in the direction away from the support portion 68.

For this reason, as shown in FIG. 5B, when the rod 74 moves to the direction in which the clamping force of the latch spring 76 resists, the position which abuts against the cam part 72 of the contact part 74A will shift | deviate and abuts. The cam portions 72 are separated from each other as the portion 74A moves around the tip portion of the cam portion 72. Thereby, the holding member 64 rotates around the support part 68, and the holding parts 70 move in the direction which mutually approaches.

That is, the cam part 72 is formed in the other end side of the holding member 64, and the movement amount of the rod 74 is converted into the rotational force which rotates the holding member 64, and the holding | gripping part 70 is approached. As a result, when the rod 74 is pressed in the axial direction, the gripping portion 70 comes close to hold the pin member 52.

As described above, the gripping portion 70 is formed on one end side of the gripping member 64 on the basis of the support portion 68 of the gripping member 64, and the cam portion 72 is provided on the other end side of the gripping member 64. It forms so that the holding | gripping part 70 may approach each other by separating cam parts 72 from each other through the rod 74. As shown in FIG.

That is, since the magnitude | size of the external force acting on the cam part 72 can be changed by the movement of the rod 74, the holding force by the holding part 70 can be changed with the support part 68 as a point. That is, the stroke of the rod 74 and the position of the support portion 68 of the gripping member 64 are changed so that the support portion 68 is larger than the distance from the support portion 68 to the portion where the contact portion 74A touches the cam portion 72. By increasing the distance from the gripping portion 70 to a large gripping force with a small force using the principle of lever.

Here, as shown in Fig. 4A, the engagement concave portion 70A is formed on the upper surface side of the grip portion 70 with the inner surface cut out, so that the grip member 64 is closed as shown in Fig. 4B. In the state, a gap is formed between the holding part 70 and the holding part 70. The pin member 52 is able to engage in this clearance.

On the other hand, the lower surface side of the holding part 70 prevents the formation of a gap almost in the state in which the holding member 64 is closed. While the pin member 52 is engaged in the gripping portion 70, the lower end of the gripping portion 70 supports the front end portion of the pin member 52 so as to shake between the pin member 52 and the gripping member 64. I do not.

5A and 5B, protrusions 72A protruding outward from each other are formed at the tip end of the cam portion 72. As shown in FIG. On the other hand, as shown in FIG. 4A and FIG. 4B, the insertion hole (hole part) 66A is formed in the side wall of the latch case 66, and the projection part 72A is inserted in the state in which the holding member 64 was closed. The gripping member 64 is inserted into the hole 66A to prevent the gripping member 64 from shaking while the gripping member 64 grips the pin member 52.

By the way, the locking piece 78 is formed in the lower portion of the holding member 64 is exposed through the lower portion of the rail 26 and located in the lower portion of the case 18 in the height direction. The rail 26 forms a gap between the attachment portion 20 (see FIG. 3), and as shown in FIG. 4A, the locking piece 78 is connected to the rail 26 in a state where the gripping member 64 is opened. ) Is caught in the tip of. At this time, the holding member 64 protrudes outward through the window hole 60.

Here, as shown in Fig. 2, the case 18 has a catching hole 80 formed in the lower portion of the window hole 60, and the catching piece 78 is caught in a state where the catching piece 78 is caught at the tip of the rail 26. The tip of 78 is inserted into the locking hole 80. In this state, the latch unit 28 is locked.

Then, when the pin member 52 abuts against the rod 74 of the latch unit 28 and the rod 74 is pressed in the direction in which the holding force of the latch spring 76 is resisted, the gripping as shown in Fig. 4B is carried out. The member 64 is closed. At this time, the tip of the locking piece 78 is removed from the locking hole 80 and the locking piece 78 is released from the locking portion of the rail 26 with the tip of the rail 26 (so-called lock release). .

(Action of moving device of moving body)

Next, the operation of the moving device according to the present embodiment will be described.

As shown in FIG. 1A, FIG. 6A, and FIG. 6B, the sliding door 10 is moved to a 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 sectional view corresponding to FIG. 1A showing the lower part of the case 18.

The guide piece 56 of the moving device 16 (refer FIG. 2) passes through the pin member 52, and the pin member 52 is a rod of the latch unit 28 as shown to FIG. 5A and 5B. When the rod 74 is pressed in the direction in which the latch spring 76 resists the holding force of the latch spring 76, the cam portion of the gripping member 64 is moved by the movement of the contact portion 74A formed on the rod 74. (72) They are widened and separated from each other. Thereby, the holding member 64 rotates around the support part 68, the holding member 64 is closed, and the holding | gripping parts 70 are close to each other, and the pin member 52 is gripped.

At this time, the front end of the locking piece 78 shown in FIG. 4A is pulled out of the locking hole 80 (see FIG. 2), and the locking piece 78 is released from the locking end with the leading end of the rail 26 (locked). Is released). In the locked state of the latch unit 28, as shown in FIG. 6B, since the elastic energy (charging force) by the tension spring 48 is accumulated, the tension spring 48 is released when the latch unit 28 is unlocked. ) Of the force of action.

Since the latch unit 28 is restricted in its movement by the pin member 52, the holding force of the tension spring 48 acts on the case 18 as shown in Figs. 1B, 7A and 7B. do. 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 through 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 sectional view corresponding to FIG. 1B showing the lower part of the case 18.

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

On the other hand, the sliding door 10 is moved to the opening direction (direction opposite to the arrow A direction) from the state shown to FIG. 7A and FIG. 7B. At this time, the latch unit 28 is moved through the sliding door 10 and the pin member 52, because the latch unit 28 is moved in the direction of resistance of the holding force of the tension spring 48 (arrow A direction). , The sliding door 10 is subjected to that much load. As a result, the sliding door 10 is not opened unintentionally.

In addition, as the latch unit 28 moves, the piston rod 44 is pulled out of the cylinder 42. For this reason, what is called drag force (<damping force) which arises when the piston moves in the cylinder 42 acts on the latch unit 28. As shown in FIG.

Then, when the latching unit 28 of the gripping member 64 reaches the tip of the rail 26 by moving the latch unit 28 through the pin member 52, the locking piece 78 of the rail 26 is moved. The front end of the locking piece 78 is inserted into the locking hole 80 so that the holding member 64 protrudes outward through the window hole 60. In this state, the latch unit 28 is restricted by movement (lock state).

As shown in FIG. 9A, the pin member 52 is released from engagement with the gripping member 64. In this state, as shown in FIG. 9B, the elastic energy (elastic force) by the tension spring 48 is shown. ) Is accumulated. 9A is a schematic plan view corresponding to FIG. 8A showing the upper part of the case 18, and FIG. 9B is a schematic sectional view corresponding to FIG. 8A showing the lower part of the case 18.

In this state, when the sliding door 10 is moved to the opening direction (arrow B direction) as shown to FIG. 8A and FIG. 8B, since the drag force by the tension spring 48 and the damper 40 does not act, it is sliding 10 becomes light.

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 Figs. 5A and 5B. As shown in FIG. 6, the pin member 54 abuts against the rod 74 of the latch unit 30 so that the rod 74 is pressed in the direction of resisting the holding force of the latch spring 76.

The cam portions 72 of the gripping member 64 are widened by the movement of the contact portion 74A formed on the rod 74, and are separated from each other. Thereby, the holding member 64 rotates around the support part 68, the holding member 64 is closed, and the holding | gripping parts 70 are close to each other, and the pin member 54 is gripped.

At this time, the front end of the locking piece 78 shown in FIG. 4A is pulled out of the locking hole 80 (see FIG. 2), and the locking piece 78 is released from the locking end with the leading end of the rail 26 (locked). Is released). 10A and 11A, the piston rod 44 is pushed into the cylinder 42 by the case 18 moving through the latch unit 30. As shown in FIG.

For this reason, the 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 an upper part of the case 18, and FIG. 11A is a schematic plan view corresponding to FIG. 8C showing an upper part of the case 18.

Here, since the tension spring 48 is connected to the latch unit 28 and the case 18 as shown in FIGS. 10B and 11B, even when the latch unit 30 is unlocked, the tension spring 48 Gripping force does not act on the latch unit 30. 10B is a schematic sectional view corresponding to FIG. 8B showing the lower part of the case 18, and FIG. 11B is a schematic sectional view corresponding to FIG. 8C showing the lower part of the case 18.

As described above, in the present embodiment, the moving device is provided on the sliding door, but the moving device may be provided on the door frame side. In this case, the pin member is installed on the sliding side. In addition, although the sliding door of the single sliding type was demonstrated in this embodiment, you may apply to the sliding door of a double sliding type. In this case, two moving devices are required. In addition, although the sliding door which moves to a horizontal direction was demonstrated here, you may apply to the sliding door which moves to a vertical direction, and this moving apparatus may be applied to a drawer etc., for example.
