Description

The present invention completely moves a moving side member such as a drawer portion of OA equipment, a placement plate portion such as furniture, a slide shelf such as a display shelf, etc., from a drawer state (slid state) to a storage position (final predetermined position). Even if it is not stored, when it is stored to a certain position, it is automatically pulled into the holding member and then held, and the moving member rebounds when the moving member is moved to the fixed member vigorously, or Both an automatic pull-in function that prevents the moving-side member from inadvertently popping out of the fixed-side member during transportation, an earthquake, etc., and an automatic push-out function that automatically pushes the moving-side member to the specified position when the holding state is released It is related with the sliding device of the movement side member which has this.

When the moving side member such as the mounting plate is stored in the stationary side member such as the furniture body, if the moving side member is stored vigorously, the moving side member may not be completely stored or moved due to rebounding during storage. The side member may not be completely stored from the beginning, which causes inconvenience during transportation of furniture and during an earthquake.
In order to solve this problem, a sliding force adding member attached to the moving side member and a sliding force passive member attached to the fixed side member corresponding to the sliding force adding member are provided. When the member approaches the final predetermined position with respect to the fixed side member, the sliding force passive member has a pressing mechanism that elastically presses a part of the sliding force passive member. There is provided a slide rail provided with a pull-in function, which is provided with a guide inclined surface that changes the pull-in force in a direction to be a final predetermined position with respect to the fixed side member. (For example, refer to Patent Document 1.)

In this case, since the sliding force passive member is configured to be attached to the storage side end of the moving member together with the sliding force adding member, the sliding force passive member is configured to be extremely short compared to the sliding distance of the moving member. The Rukoto.
Therefore, the distance between the pull-in start position and the pull-in end position is shortened, and a preferable pulling effect is obtained such that the pulling is suddenly performed, or a pulling force more than expected is required to pull out the stored and held moving side member. I couldn't.

On the other hand, devices that are often used with both hands closed, drawers that do not have a puller for design reasons, etc., release the holding state from the holding state at the final predetermined position, or once The push-in operation is followed by a push-out function that automatically pulls the drawer out to a predetermined position. A fixed rail is attached to the movable rail with a pulley mechanism so that it can move in the longitudinal direction of the fixed rail. One end of a wire wound in a U-shape around the pulley of the mechanism is attached to one end of the moving rail, and the other end is attached to one end of the stationary rail, and the pulley mechanism and the other end of the stationary rail are There is provided a structure having a tension spring in between. (For example, refer to Patent Document 2.)

In this case, the wire, the pulley mechanism, the pulley mechanism, and the tension spring are all disposed between the fixed side rail and the moving side rail.
For this reason, in the process of assembling the slide rail main body composed of the fixed side rail and the moving side rail, a wire, a pulley mechanism, and a tension spring have to be incorporated in advance, resulting in a problem that production efficiency is very poor.
Further, when a failure occurs in the wire, pulley mechanism, and tension spring, since the failure is incorporated in the inside, only the failed portion cannot be replaced, and the entire slide rail needs to be replaced, resulting in high costs.

On the other hand, in particular, high-quality OA equipment (particularly copying machines) or high-quality system kitchens, etc. have been required to have high functions in each part in order to bring out a high-class feeling.
For example, there has been a strong demand for a paper tray in a copying machine and a drawer in a system kitchen to have both an automatic drawing function and an automatic extrusion function.
However, since the automatic pull-in function and the automatic push-out function have contradictory movements, electrical equipment using a motor was provided, but it was very expensive and had problems with repairs at the time of failure, etc. .

JP 2007-195754 A JP-A-4-161108

In view of the above problems, the present invention can be manufactured with a simple structure at low cost, and an automatic pull-in function and an automatic push-out function can be mechanically provided between the moving side member and the fixed side member regardless of the structure of the slide rail. It is an object to provide a sliding device for a moving member.

  In order to solve the above-mentioned problems, the first feature of the present invention is that the sliding force adding member attached to either the fixed side member or the moving side member and the other corresponding to the sliding force adding member A sliding force passive member having a length substantially equal to the sliding distance of the moving member, and a latch member provided between the moving member and the fixed member that holds the moving member in a retracted state. Thus, the sliding force adding member is always elastically applied only in one direction, and a part thereof is elastically pressed against the sliding force passive member, and the sliding force passive member is unidirectionally applied to the sliding force adding member. It has a conversion mechanism that converts the elastic force into a pulling force when the moving side member reaches a predetermined position, pulls the moving side member to a predetermined position, and converts it into a pushing force when the drawn moving side member reaches the predetermined position. The latch member has a sliding force application part. Unidirectional elastic force applied to the can in a state of change in the extrusion force from drawing force of the movable member is to hold the movable member temporarily in a stopped state.

Next, the second feature of the present invention is not limited to the configuration of the first means, but the conversion mechanism is adapted to the sliding force adding member when the moving side member reaches a predetermined position by the storing force from the outside. A pull-in guide path that converts the applied elastic force in one direction into a pull-in force of the moving member, and a one-way applied to the sliding force adding member when a part of the drawn moving-side member reaches a predetermined position The pull-in guide path and the push-out guide path are continuous via the conversion guide path at the storage side end.

Next, the third feature of the present invention is that, in addition to the configuration as the second means, the sliding force adding member is always pushed by the rotating roller provided at the tip portion and the pulling guide path of the conversion mechanism. It has an elastic pressure contact arm loaded with an elastic force so as to be pressed against the guide path, and the pull-in guide path is inclined in a direction in which the pressure contact force of the rotating roller changes the moving side member to the fixed side member into the pulling force, The push-out guide path is inclined in such a direction that the pressing force of the rotating roller changes the push-force to the moving side member with respect to the fixed side member, and an open / close sliding path is provided on the pull-out side of the pull-in guide path. A drawer slide path is provided between the open / close slide path, and the continuous part of the drawer slide path and the open / close slide path is configured so that the rotating roller can pass only in the direction from the drawer slide path to the open / close slide path. What is being That.

According to the first aspect of the present invention, the structure is constituted only by the sliding force adding member, the two members of the sliding force passive member attached corresponding to the sliding force adding member, and the latch member. It is simple, has a small number of members, is easy to assemble, and can be manufactured at low cost.
Further, by providing the sliding force addition member and the sliding force passive member outside the slide rail, any slide rail configuration can be used.
Furthermore, since the sliding force addition member has a simple configuration that only applies an elastic force in one direction, no failure occurs and a stable sliding state can be obtained.
Further, since the sliding force passive member is provided with a length substantially equal to the sliding distance of the moving side member, the predetermined position where the moving side member is drawn can be determined from a wide range, so that the desired storage feeling can be obtained. (Pulling sensation) and pulling sensation can be obtained.
Further, since the latch member is provided between the moving side member and the fixed side member, which is not related to the sliding force adding member and the sliding force passive member, an operation member for operating the latch member is formed on the moving side member, for example. The latch can be released at a desired position, for example, by being provided on a puller.

According to the second aspect of the invention, in addition to the above effects, the conversion mechanism has a simple configuration including the pull-in guide path and the push-out guide path. Therefore, the conversion mechanism can be manufactured at low cost and there is almost no cause for failure.
In addition, since the pull-in guide path and the push-out guide path are formed continuously through the conversion guide path at the storage end, there is no sense of incongruity even when the sliding of the moving side member changes from the pull-in movement to the push-out movement. A smooth sliding state can be obtained.

According to the invention described in claim 3, in addition to the effect of the invention described in claim 2, since the sliding force addition member has a rotating roller, even if it is in pressure contact with the drawing guide path and the pushing guide path, Does not affect the sliding of the moving side member.
Further, since the push guide path and the pull-in guide path are inclined in the direction in which the pressing force of the rotating roller changes to the push-out force or pull-in force of the moving member, the structure is simple and can be manufactured at low cost.
Furthermore, an opening / closing sliding path is provided on the pulling side of the drawing-in guide path, and a drawer sliding path is provided between the pushing guide path and the opening / closing sliding path. Since the rotating roller can pass only in the direction of the opening / closing sliding path from the drawer sliding path, the rotating roller includes the opening / closing sliding path, the pull-in guide furnace, the extrusion guide path, the drawer sliding path, and the opening / closing slide. It circulates securely with the furnace and exhibits stable pull-in and push-out functions.

  A sliding force addition member attached to either the fixed side member or the movement side member and a length substantially equal to the sliding distance of the movement side member attached to the other side corresponding to the sliding force addition member. A sliding force passive member and a latch member which is provided between the moving side member and the fixed side member and holds the moving side member in a retracted state. The sliding force adding member is always given elastic force only in one direction, The rotating roller provided at the tip elastically presses against the sliding force passive member. When the moving side member reaches a predetermined position by the storage force from the outside, the pressing force of the rotating roller is moved to the moving side member. When the retracted guide path that inclines in the direction that changes to the pulling force that pulls in and the retracted moving side member reaches a predetermined position, the pressing force of the rotating roller tilts in the direction that changes to the pushing force that pushes out the moving side member. A pulling guide path, an open / close sliding path provided on the drawer side of the pulling guide path, and a pulling slide path provided between the extrusion guide path and the open / close sliding path.

The end surface on the drawer side of the ball retainer 4 is in contact with the stopper 14 when moving on the fixed side via the buffer member.

On the other hand, when the slide rail 100 is in the shortest contracted state, the stopper 23 at the time of withdrawal of the ball retainer is formed at the end of the drawer side of the intermediate member 3 by the stopper 23 at the side of withdrawal of the movable member 2 through the buffer member. 26, the stopper 27 when retracting the ball retainer formed at the end on the storage side of the intermediate member 3 contacts the stopper 15 when retracting at the fixed side formed on the end of the storage side of the fixed member 1 via the buffer member. It touches.

As shown in FIGS. 3 to 11, the sliding device 500 for the moving side member 203 disposed between the fixed side member 200 and the moving side member 203 accommodates the moving side connecting seat 204 connected to the moving side member 2. The sliding force adding member 81 attached to the side end portion, the sliding force passive member 82 attached to the fixed side fixed side connecting seat 202, and the fixed side fixed side connecting seat 202 holding the moving side member 200 in the retracted state. The latch member 83 is configured.

The sliding force adding member 81 includes a bullet member 811 and an elastic pressure contact arm 812 to which turning force is applied in a predetermined direction by the bullet member 811.
The elastic pressure contact arm 812 is a metal plate that is flat in the thickness direction of the slide rail 100 and long in the pull-out direction, and the pull-out side end portion is pivotable to the storage-side end portion of the moving-side coupling seat 204 by the pivot 813. A rotating roller 814 is rotatably attached to the distal end side (storage side end).

The elastic body 811 is formed of a wound spring material, and is externally fitted to the pivot 813. One end is locked to a locking pin 815 provided on the moving side connecting seat 204 on the moving side of the pivot 813, and the other end is pivoted. 813 is locked to a part of the elastic pressure contact arm 812 on the storage side, and the turning force is always applied in the clockwise direction in FIGS.
That is, the rotary roller 814 is always elastically pressed against the sliding force passive member 82 by the rotational force of the elastic body 811 applied to the elastic pressure contact arm 812.

The sliding force passive member 82 is located below the connecting board 820 connected to the fixed side connecting seat 202 and the slide rail 100, and the drawer side end is stored from substantially the same position as the drawer side end of the fixed side member 1. Horizontal open / close sliding path 821 formed in the direction, conversion mechanism 5 provided continuously on the storage side of the open / close sliding path 821, and provided continuously at the end of the conversion mechanism 5 on the drawer side. The drawer side end portion has a drawer sliding path 822 that is continuous between the opening / closing sliding path 821 and the second opening / closing sliding path 51 and is inclined upward in the pulling direction.

The conversion mechanism 5 includes a second open / close sliding path 51 connected to the storage end of the connection board 820 in a freely rotatable manner, and a second open / close sliding path 51 continuous to the open / close sliding path 821 on the upper surface portion. A retracting guide path 52 that inclines downward in the storing direction continuous with the storing side end of the moving path 51 and converts the elastic pressure contact force of the rotating roller 814 into the retracting force of the moving member 203 (moving member 2). A guide turning member 50, a conversion guide passage 54 having a passing gap of the rotating roller 814 and a lower end formed in a curved shape in the pull-out direction from the storage side end portion of the pull-in guide passage 52, and a conversion An extrusion guide path 55 that inclines downward in the pulling direction continuous from the lower end of the guide path 54 to the pulling side and converts the elastic pressure contact force of the rotating roller 814 into the pushing force of the moving member 203 (moving member 2). Possess The drawer side continuously drawer slideway 822 is formed.

Then, the drawer-side end portion of the second opening / closing sliding path 51 is cut at the same angle as the inclination angle of the drawer sliding path 822 to form an inclined contact surface 510 (shown in FIG. 10). The second opening / closing sliding path 51 and the opening / closing sliding path 821 are continuous in the same horizontal plane in a state where the inclined contact surface 510 is in contact with (adhered to) the upper surface of the end portion (upper end) of the lead-out side 822. Is formed.

That is, the guide rotation member 50 is rotatably held at the storage-side end portion on the connection substrate 820, and due to its own weight, the drawer-side end portion is in close contact with the upper end portion of the drawer slide path 822, and is rotated downward. Therefore, the rotating roller 814 always moves from the opening / closing sliding path 821 to the second opening / closing sliding path 51 and does not move from the opening / closing sliding path 821 to the pulling sliding path 822.
On the other hand, since the drawer side end of the guide rotation member 50 can rotate upward 5, the rotating roller 814 pushes up the drawer side end of the guide rotation member 50 from the drawer slide path 822 to open and close. Move to the road 821 without hindrance.

Reference numeral 825 (shown in FIG. 4) is an upper or a drawer at the end of the open / close sliding path 821, the drawer sliding path 822, the push-out guide path 55, and the conversion path guide path 54 on the moving side connecting seat 204 side. The detachment protrusion ridge is provided so that the rotating roller 814 moves reliably in each guide path, and the reference numeral 501 denotes a moving side coupling seat 204 for the second opening / closing sliding path 51 and the retracting guide path 52. The rotation part detachment protrusion ridge similar to the detachment protrusion 825 formed to protrude upward at the end on the side is shown.

The latch member 83 is positioned above the drawer side end of the slide rail 100 and is rotatably attached to the fixed side coupling seat 202.
When the moving member 2 slides, the lower surface of the locking claw 831 formed at the drawer side end always abuts on the upper surface of the upper bent edge 21 of the moving member 2 by its own weight, and the slide rail 100 Since the drawer side end of the movable member 3 is positioned on the storage side of the locking claw 831 slightly before reaching the shortest contracted state, the movable member 3 rotates downwardly from the upper bent edge 21 and moves downward. 2, the movable side member 2 is prevented from sliding in the pulling direction.
Further, the latch member 83 is configured to be interlocked with an operation portion such as a handle formed on the moving side member 203 or a release operation portion of the latch member 83 provided on the fixed side member 200 so that the left and right can be interlocked simultaneously. Has been.

The first embodiment is configured as described above, and the sliding force when the slide rail 100 is pulled out most (the state shown in FIG. 5), that is, the moving side member 203 is completely pulled out from the fixed side member 200. The rotating roller 814 provided on the elastic pressure contact arm 812 of the additional member 81 is elastically pressed to the middle part of the opening / closing sliding path 821 and slightly forward, and the lower surface of the locking claw 831 of the latch member 83 is connected to the movable member 2. It stops in contact with the upper surface of the upper bent edge 21.

When the moving member 203 is manually stored from this state, the sliding force adding member 81 is also moved in the storing direction, and the rotating roller 814 is moved from the opening / closing sliding path 821 to the second opening / closing sliding path. When passing through 51 and positioned at the end of the pull-in guide path 52 on the drawer side (state shown in FIG. 6).
Since the retracting guide path 52 is inclined downward in the storing direction, the rotating roller 814 (moving side member 203) is automatically pulled in the storing direction by the elastic pressure contact force of the rotating roller 814. A state in which the retracting guide path 52 is located in the passage gap 53 from the storage side end (the state shown in FIG. 7, that is, in the shortest contracted state of the slide rail 100), Since the latch member 83 is rotated downward to be in the locking posture by passing to the storage side of the locking claw 831), the storage side of the extrusion guide path 55 continuous from the lower end of the conversion guide path 54. Reach the end.

Then, since the pushing guide path 55 is inclined downward in the pulling direction, the rotating roller 814 (sliding force adding member 81, that is, the moving member 203) is automatically pulled in the pulling direction by the elastic pressure contact force of the rotating roller 814. However, since the locking claw 831 of the latch member 83 is locked to the drawer side end of the moving member 2, the sliding of the moving member 2 (moving member 203, sliding force adding member 81) is stopped. Thus, the storage state of the moving member 203 is maintained.
That is, the moving side member 203 is automatically retracted from the predetermined position, and then held at the predetermined position in a state of being pushed slightly forward.
The movement of the moving side member 203 is particularly constrained by the movement of a paper tray used in a high-quality copier. In other words, in order to store the copy paper at a predetermined position, it is possible to obtain a more reliable and stable stop position by automatically pushing and stopping the tray from the state where the tray is once stored. It is.

Next, by operating the release operation part of the latch member 83 provided in the operation part such as a pulling hand formed on the moving side member 203 or the like, the locking state of the locking claw 831 with respect to the moving side member 2 is changed. When released, the rotation roller 814 (sliding force adding member) is caused by the elastic pressure contact force of the rotation roller 814 located on the end side on the storage side of the extrusion guide path 55 and the downward inclination in the pull-out direction of the extrusion guide path 55. 81, that is, the moving member 203) automatically moves in the pulling direction and reaches a predetermined position and stops. (State shown in FIG. 9)
When the moving side member 203 is further pulled out manually, the rotating roller 814 pushes up the drawing side end of the guide rotation member 50 from the drawing sliding path 822 (the state shown in FIG. 10) and moves to the opening / closing sliding path 821. Eventually, the moving member 203 is completely pulled out. (The state shown in FIG. 5)

In the first embodiment, the sliding force adding member member 82 is provided on the moving side and the sliding force passive member 81 is provided on the fixed side. However, in FIG. 5, the latch member 83 is provided in the reverse direction. The fixed member 1 is a moving member, and the moving member 2 of the first embodiment is used as a fixed member, so that the sliding force passive member 81 is moved together with the moving member in the first embodiment. The same effect can be obtained.
In the first embodiment, the sliding force passive member 82 and the sliding force adding member material 81 are connected to the slide rail 100 via the fixed side connecting seat 202 and the moving side connecting seat 204. In addition, the fixed side member 200 and the moving side member 203 may be directly attached.

Next, a second embodiment will be described with reference to FIGS.
The slide rail 100 of the second embodiment is disposed between the fixed member 1, the movable member 2 that is slidable on the fixed member 1 and substantially the same length, and is disposed between the fixed member and the movable member. A ball retainer 4 having a length of about a quarter of the member 1 and a ball that is rotatably held by the ball retainer 4 and rolls between the upper and lower bent edges of the fixed member 1 and the movable member 2. 40...

The sliding force adding member 81 is configured in the same manner as in the first embodiment.
The sliding force passive member 82 has an upper end connected to the fixed member 1 and directly connected to the fixed member 200. As in the first embodiment, the horizontal opening / closing sliding path 821 and the storage side of the opening / closing sliding path 821 are connected. Are provided continuously to the end of the conversion mechanism 5 on the drawer side and inclined upward in the pull-out direction. There is a continuous drawer slide path 822 between the two open / close slide paths 51.

The conversion mechanism 5 has a storage side end rotatably connected to a storage side end of the connection substrate 820, and is inclined more gently than the pull-in guide path 52 of the first embodiment connected to the opening / closing sliding path 821 on the upper surface portion. The guide turning member 50 having the pull-in guide path 520 and the storage-side end portion of the pull-in guide path 52 have a passage gap 53 of the rotating roller 814, and the lower end is formed in a curved shape in the pull-out direction in the vertical direction. The conversion guide path 54 and the lower end of the conversion guide path 54 are inclined downward in the pulling direction continuous to the pulling side, and the elastic pressure contact force of the rotating roller 814 is used as the pushing force of the moving member 203 (moving member 2). An extrusion guide path 55 to be converted is provided, and a drawer slide path 822 is formed continuously on the drawer side.

That is, the second embodiment differs from the first embodiment only in the structure of the slide rail 100, the attachment of the sliding force passive member 82, and the configuration of the guide rotation member 50, and the other configurations are substantially the same.
The effect is also the same.
However, since the pull-in guide path 52 is inclined more gently than the first embodiment and extends to the end of the open / close sliding path 51 on the drawer side, the elastic force is stronger than the elastic body 811 of the first embodiment. Thus, the drawing start position of the moving member 203 is made closer to the drawing side direction.

Claims (3)

A sliding force addition member attached to either the fixed side member or the movement side member and a length substantially equal to the sliding distance of the movement side member attached to the other side corresponding to the sliding force addition member. It consists of a sliding force passive member and a latch member provided between the moving side member and the fixed side member that holds the moving side member in a retracted state. The sliding force adding member is always given elastic force only in one direction. Part of it is elastically pressed against the sliding force passive member. The sliding force passive member converts the unidirectional elastic force applied to the sliding force adding member into a pulling force when the moving side member reaches a predetermined position. The moving member is pulled to a predetermined position, and when the retracted moving member reaches the predetermined position, it has a conversion mechanism that converts it into a pushing force, and the latch member has a one-way elastic force applied to the sliding force adding member. Is the pulling force of the moving member In state changed to Luo extruding force, the sliding device of the movable member, characterized in that for holding the movable member temporarily in a stopped state. The conversion mechanism includes a pull-in guide path that converts the elastic force in one direction applied to the sliding force adding member into the pulling force of the moving side member when the moving side member reaches a predetermined position by the storing force from the outside, When a part of the retracted moving side member reaches a predetermined position, it has an extrusion guide path that converts the elastic force in one direction applied to the sliding force adding member into an extrusion force, and the retracting guide path and the extrusion guide path are stored. 2. The sliding device for a moving member according to claim 1, wherein the sliding device is continuous at a side end portion via a conversion guide path. The sliding force addition member has an elastic pressure contact arm loaded with an elastic force so that the rotating roller provided at the tip always comes into pressure contact with the pulling guide path and the pushing guide path of the conversion mechanism. The pressing force of the roller tilts in the direction that changes the moving side member to the pulling force with respect to the fixed side member, and the pushing guide path changes the pressing force of the rotating roller to the pushing force of the moving side member to the fixed side member The open / close sliding path is provided on the pull-out side of the pull-in guide path, and the drawer slide path is provided between the push-out guide path and the open / close slide path. 3. The sliding device for a moving member according to claim 2, wherein the continuous portion is configured such that the rotating roller can pass only in the direction of the open / close sliding path from the drawer sliding path.
