  In Patent Documents 1 and 2, a runner body that travels on rails arranged on a duck, a sill, etc., a connecting member that is attached to a door plate, and a support shaft that is supported by the runner body and is detachably connected to the connecting member. And the connecting member includes a main body portion that is connected to a support shaft with a vertical adjustment mechanism that adjusts the vertical position of the door plate, and a cup portion that is attached to the side surface of the door plate and engages and detaches the main body portion. A runner device is described.

  In the runner device according to Patent Documents 1 and 2, the connecting member divided into the main body portion on the support shaft side and the cup portion on the door plate side can be detached and attached by one-touch operation. The shaft can be attached and detached with a single touch.

In Patent Documents 1 and 2, the connecting member in the runner device is attached by forming a storage space by drilling or the like from the side surface of the horizontal frame of the wooden doorboard.
However, in the case where the door plate is an aluminum frame composed of an aluminum vertical frame and a horizontal frame, if the side surface of the horizontal frame is processed to make a hole, there is a problem that the strength is lowered and the design is inferior.

  That is, since the aluminum frame is generally a hollow body formed by extrusion, the side surface of the horizontal frame has a structure that contributes to strength maintenance. Therefore, if such a portion is drilled, the suspension strength is weakened and the portion is easily deformed. In particular, since the drilling is performed from one side surface, the load balance is likely to be lost and the deformation is likely to occur. Moreover, since the processed part appears in the table, the design is inferior.

  Of course, in order to avoid such a problem, it is possible to attach the connecting member to the upper surface of the horizontal frame (not embedded in the door plate), but in this case, since the connecting member is located between the horizontal frame and the rail, these gaps However, there is a problem that the product value is lowered from the viewpoint of design.

    The present invention has been made in consideration of such problems, and provides a runner device that can be attached to an aluminum frame door plate without deteriorating the design and without causing a decrease in strength. This is the issue.

    In order to solve the above-described problems, the runner apparatus according to the present invention employs means described in each of the claims.

    That is, in claim 1, a runner body that travels on a rail disposed on a duck, a sill, etc., a support shaft supported by the runner body, and a small block engagement body connected to the lower end of the support shaft A coupling provided with a main body portion in which an engagement receiver to which the engagement body engages and detaches and a vertical adjustment mechanism for moving the engagement receiver up and down by operating an operation screw is connected. And the main body portion is embedded from the upper surface portion of the horizontal frame of the door plate made of an aluminum vertical frame and a horizontal frame, and at this time, the operation screw is not in contact with at least the horizontal frame. An embedding position is defined by contacting an edge of the upper surface of the horizontal frame at an operable position, and a flange that is fixed to the upper surface of the horizontal frame with a screw is provided.

  As a result, the aluminum frame door plate can be attached without impairing the design and without causing a decrease in strength.

  According to a second aspect of the present invention, in the runner device according to the first aspect, the engaging member of the connecting member is connected to the support shaft near the engaging front end and has an elasticity near the engaging rear end. In addition, the engagement receiver of the connecting member is provided with an engagement groove with which the engagement piece engages.

  Thus, even a heavy aluminum frame door plate can be easily attached without impairing the design and without causing a decrease in strength.

At this time, when an operation screw 45 of the vertical adjustment mechanism 4 to be described later is exposed from the horizontal frame and the operation screw 45 is operated by a screwdriver or the like, the driver does not interfere with the operability by contacting the horizontal frame Pb. To do.

  Therefore, even if it is a door plate made of an aluminum frame, the side face of the horizontal frame is not perforated, etc., so that the suspension strength is reduced and it becomes easy to deform, or the processed part appears on the table and the design property is deteriorated. Accordingly, the horizontal adjustment of the door plate P and the gap adjustment between the horizontal frame Pb and the rail R can be easily performed while ensuring the operability of the operation screw 45 to the minimum, and the quality can be improved.

  Moreover, since only the small block type engaging body 31 which is the small volume of the connection member 3 exists between the rail R and the door board P, the installation space required between the rail R and the door board P is required. Can be made small to improve the appearance of the doorboard P.

The engagement of the connecting member 3 is reliably held by the engagement between the engagement piece 31e of the engagement body 31 and the engagement groove 322a of the engagement receiver 322 of the main body 32.
Therefore, the engagement of the connecting member 3 does not occur unexpectedly and the door plate P does not fall.

Further, since the support shaft 2 is positioned at the engagement tip portion of the engagement piece 31e of the engagement body 31 and is located at substantially the center of the main body portion 32 of the connecting member 3, the overall load balance is improved.
Therefore, the load is not unevenly distributed on a part of the connecting member 3 and damage is not caused.

  To release the engagement of the connecting member 3, the engagement between the engagement piece 31 e of the engagement body 31 and the engagement groove 322 a of the engagement receiver 322 of the main body 32 is released, and the engagement reception of the main body 32 is received. The engagement body 31 is slid away from the 322.

  At this time, if a tool such as a flat-blade screwdriver is inserted from the operation groove 322b of the engagement receiver 322 of the main body 32 to push down the engagement piece 31e of the engagement body 31, the engagement piece 31e and the engagement groove 322a The engagement can be easily released.

  Further, since the operation groove 322b of the engagement receiver 322 of the main body 32 is located on the end side of the main body 32 that is the rear end side of the engagement, the main shaft 32 and the main body 32 of the connecting member 3 are It does not interfere with work using tools.

  The vertical adjustment mechanism 4 rotates the drive screw 44 and the driven gear 43 by rotating the operation screw 45, and the drive gear 44 is operated by the driven gear 43 that moves up and down in the axial direction of the screw portion 42 b of the shaft 42. The lift slider 41 is moved up and down via the screw 45.

  The raising / lowering movement of the raising / lowering slider 41 includes a guide between the vertical frame 41a and the casing 321 of the main body 32 of the connecting member 3, a guide between the pin 41c and the guide hole 321b provided in the casing 321, and a shaft hole. 41d and the shaft 42 are played accurately and smoothly.

  When the elevating slider 41 is moved up and down, the interval S between the rail R and the door plate P is adjusted, and the vertical position of the door plate P is adjusted.

  The operation of the vertical adjustment mechanism 4 can be performed continuously with the engaging operation of the connecting member 3 because the operation screw 45 is disposed close to the engaging portion of the connecting member 3.

  In addition, since the drive system (the shaft 42, the driven gear 43, the drive gear 44, and the operation screw 45) of the up-and-down adjustment mechanism 4 and the attaching / detaching portion (engaging portion) of the connecting member 3 are configured separately, It is possible to prevent damage and failure of surrounding members due to operation.
