Is a sliding door that is supported by the runner device, so as to open and close the structure by traveling along guide rails.

A lock mechanism is provided between the support unit and the mounting member to fit and lock the support unit in the mounting member. One conventional example of this type of runner device is disclosed in Japanese Patent No. 3,359,296 (Japanese Patent Application Laid-Open No. 2000-204483). In this prior art, the lock mechanism is composed of a lock groove provided at the bottom of a mounting member previously mounted on the door plate side, a lock arm provided swingably in the support tube, and a support unit. A spring urging means for urging the hook arm into the lock groove of the mounting member and locking the support unit to the mounting member while being fitted into the member. When the support unit is fitted into the mounting member and moved to a predetermined mounting position, the lock arm is engaged with the lock groove by the spring biasing means and locks the support cut to the mounting member. In addition, when the lock arm is lifted so as to escape from the lip groove against the urging force of the spring urging means, the lip of the support unit with respect to the mounting member is released. Can be removed from. In this prior art runner device, the operating end of the lock arm is exposed on the end surface of the support unit so that the support cut can be released from the lock of the mounting member, so that the lock arm can be easily attached to the lock arm. They can be accessed (see Figures 1 and 2 of the same publication).

However, if the tip of the lock arm is easily accessible as described above, the lip arm is accidentally moved, the lip state of the lip mechanism is inadvertently released, and the door plate is detached from the runner device. There is a risk of doing so.

In this type of runner device, a door plate front-rear position adjustment mechanism for adjusting the position of the support unit in the front-rear direction (thickness direction of the door plate) with respect to the suspension rod is provided by an operating screw exposed on an end face of the support unit.

The arcuate surface of the suspension rod is engaged with the inclined surface of the guide groove having an inclined surface inclined with respect to the longitudinal direction of the slider, and the horizontal displacement in the direction parallel to the plate surface of the door plate of the slider is applied to the inclined surface of the guide groove. The horizontal displacement in the oblique direction is converted into a horizontal displacement, and the longitudinal displacement component included in the oblique displacement is used to adjust the position of the door plate in the longitudinal direction with respect to the suspension rod.

However, in the front-rear position adjustment mechanism having such a structure, since the guide inclined surface of the guide groove of the slider and the suspension rod relatively move over a considerable distance, wear loss occurs and the position adjustment accuracy is reduced. In addition, the suspension rod must be formed not in a round bar shape with a circular cross section but in a substantially rectangular cross section having a pair of flat surfaces and an arc-shaped surface. And the drawback is that it is difficult to reduce the size of the runner device.

An object of the present invention is to provide a runner device that can securely hold a door plate without a support unit being unintentionally detached from an attachment member.

Another object of the present invention is to provide a runner device that can adjust the position of a door plate smoothly and accurately while minimizing wear between components when the position of the door plate is adjusted in the front-rear direction (thickness direction).

As described above, the jig T is operated through the operation window hole 4 1b to operate the movable hook member 6 1 [At least the end of the jig T is inserted upward while being inserted into the I! Portion 6 1 e. When lifted, the movable hook member 6 1 swings upward around its shaft 6 1 b, and the locking projections 6 1 d become vertical locking surfaces 6 2 b of the fixed hook portions 6 2 Away from it. As a result, the support unit 4 can move to the left with respect to the mounting member 5, so that the support unit 4 can be removed from the installation concave portion: P3.

As shown in FIG. 1, between the support unit 4 and the suspension rod 3, there is a door plate front and rear position for adjusting the position of the door plate P in the front and rear direction (W direction in FIG. 2) with respect to the guide rail R. An adjustment mechanism 7 and a vertical position adjustment mechanism 8 for adjusting the position of the door plate P in the vertical direction with respect to the guide rail R are provided.

As shown in FIGS. 1, 4, and 8, the door plate front-rear position adjustment mechanism 7 is provided in the support unit 4, and is prevented from moving in the left-right direction (the L direction in FIG. 1).

And direction changing means 75 for converting the horizontal displacement of the linear slider 72 in the left-right direction into the horizontal displacement in the front-rear direction.

The rotation operation screw 71 is prevented from moving left and right by the locking plate portion 42 of the support unit 4. The linear slider 72 has a substantially U-shape, and the turning screw 71 is screwed to the base of the linear slider 72. Therefore, when the rotation operation screw 71 is rotated in the forward and reverse directions, the linear slider 72 moves in the left and right direction (the L direction in FIGS. 4 and 8). As shown in FIGS. 1 and 2, the head 71 H of the rotary operation screw 71 is exposed from the window hole of the shielding wall 41. The head 7 1 H has an annular groove 7 lH g into which the locking plate portion 42 is engaged, so that the rotating operation screw can be rotated by using an appropriate jig such as a cross driver. 7 1 does not move in the left-right direction (L direction in Fig. 1).

The direction changing means 75 is provided in the support unit 4 as shown in FIG. It consists of a swinging guide 73 that makes a circular motion (swings) in the front-rear direction while maintaining the horizontal state with the base shaft 74 (see Fig. 1) as the center. As shown in FIG. 4, the swing guide 73 has a starting neck 73 a protruding from one side thereof and a substantially spherical head 7 provided at the tip of the starting neck 73 a. 3b, and the starting neck 73a penetrates a pivotal recess 72a provided in the linear slider 72 and is pivotally supported while being prevented by a substantially spherical head 73b. Thus, the linear displacement of the linear slider 72 is converted into a swing (rotation) displacement (see R in FIG. 8) including a displacement component of the swing guide 73 in the front-rear direction.

This swing guide 73 has a position adjustment hole 73H of a substantially elliptical shape at its free end, while the adjustment rod 32 of the suspension rod 3 has a circular cross-sectional form. The adjusting rod 32 is passed through the position adjusting hole 73 a of the driving guide 73. As can be seen from FIG. 8, the ellipse of the position adjusting hole 73a indicates that the adjusting rod 32 of the suspension rod 3 cannot move in the front-rear direction (W direction in FIG. 2), but in the left-right direction (first (L direction in the figure). Therefore, when the linear slider 72 is moved in the left-right direction by the rotating operation screw 71, the swing guide 73 swings, and the inner surface of the position adjusting hole 73a is formed around the adjusting rod 32. The free end thereof is displaced in the front-rear direction while rolling contact with the roller.

A pair of horizontal shaft rods 83 of the adjusting rod portion 32 of the rod 3 penetrates the cam member 82 so as to engage with these cam surfaces 82a, 82a. Therefore, it can be seen that the support unit 4 is supported by the suspension rod 3 via the shaft rod 83 and the cam member 82.

When the rotation operation screw 81 is rotated in the forward and reverse directions, the cam member 82 moves in the left-right direction, and the cam member 82 is displaced in the vertical direction with respect to the suspension rod 3, so that the support unit is G is displaced in the vertical direction. Therefore, it can be seen that the height (the vertical position) of the door plate P with respect to the guide rail R is adjusted according to the amount of rotation of the rotation operation screw 81.

When the door plate P is suspended and supported on the guide rail R using the runner device 1 of the present invention, the suspension rod 3 is attached to the traveling body 2 and the suspension rod 3 Attach support cut 4 to When the support unit 4 is mounted on the suspension rod 3, the suspension rod 3, the front-rear position adjustment mechanism 7, the vertical position adjustment mechanism 8, and the movable lock member 6 1 Is installed. After that, while inserting the locking plate portion 42 of the other half 4B into the housing groove 41a of the shielding wall 41, the halves 4A and 4B are butted together and fixed by bonding or the like. In this way, the support unit 4 is suspended and attached to the suspension rod 3. .

Thereafter, as shown in FIG. 6, the traveling body 2 is placed on the guide rail R, and the mounting member 5 is fixed to the installation recess P 3 of the door plate P. Next, the support unit 4 is moved in the horizontal direction together with the traveling body 2 to enter the installation recess P3. When the support unit 4 reaches the final mounting position of the mounting recess P3, the tip of the stopper piece 53 of the mounting member 5 abuts against the left end surface of the engaging recess 45 of the support unit 4, and the mounting member 5 The support ridges 5 5 are fitted into the support grooves 44 of the support unit 4, and the locking projections 6 1 d of the movable hook member 6 1 are locked by the fixed lock portions 62 so that the support unit 4 To the mounting member 5. In this way, the support unit 4 is attached to the door plate P via the attachment member 5, and as a result, the door plate P is suspended and supported by the traveling body 2. Therefore, the door plate P can close or open the opening of the structure by pushing the door plate P left and right by hand.

When removing the door plate P from the holding unit 4, as shown in Fig. 7, insert a jig T such as a screwdriver through the operation window hole 41b of the shielding wall 41 into the support unit 4. Then, the tip of the jig T is inserted into the operation recess 6 le of the movable lock member 6 1, and the movable lock member 6 1 of the lock mechanism 6 is biased by the leaf spring 6 1 c into the jig T. To lift the movable lock member 61 and the fixed lock member 62. In this case, the middle part of the jig T is placed on the lower surface of the operation window hole 41b, and the jig T is swung counterclockwise in FIG. 1 around the corner of the operation window hole 41b. Thereby, the free end of the movable lock member 61 can be easily lifted. Then, the support unit By moving 4 to the left, the support ut 4 can be removed from the installation recess P3.

In the above-described runner device 1, the movable hook member 61 of the hook mechanism 6 is shielded from the outside by a shielding wall 41 except for a portion facing the operation window hole 41 b. Also, since the movable lock member 61 is retracted inward from the outside opening of the operation window hole 41b by an amount corresponding to the thickness of the shielding wall 41, the movable lock member 61 moves unintentionally. As a result, the lock between the movable hook member 61 and the fixed hook portion 62 is not released.

In addition, the door plate front-rear position adjustment mechanism 7 has a direction changing means for converting the left-right displacement of the slider into the front-rear displacement of the support tube, as in the prior art, in linear sliding contact. Instead, the linear displacement of the slider is converted into oscillating motion, and this sliding motion is performed by rolling contact with the adjusting rod of the suspension rod. In addition to avoiding deterioration of durability due to loss, the suspension rod adjustment rod can be left as a round bar, eliminating troublesome work such as special cutting of the suspension rod. You can also.
