Description

  The present invention relates to a gap closing device for a sliding door that can exhibit an effect of preventing light leakage from a gap between a vertical and a sliding door, that is, a shielding effect.

  JP 2011-132687 A   Japanese Patent No. 4487408

  In general, a sliding door frame provided in a building window or the like has a so-called neutral structure in the vertical direction at the partition between the opening and the wall of the sliding door frame. As a structure, it is described in Japanese Patent Application Laid-Open No. 2011-132687, Japanese Patent No. 4487408, and the like, but a neutral member in which a storage groove opening on the side facing the sliding door is formed along the vertical direction, and this middle Various types of sliding doors having a gap closing device that is retractably stored in a storage groove of a standing member have been developed.

  As a conventional sliding door gap closing device, a gap closing member such as a filler or mohair is converted into a linear movement by using a cam mechanism or a rack-pinion mechanism, and a neutral member is moved by moving in a lateral direction. There is one that closes the gap between sliding doors.

  The sliding door gap closing device described in Japanese Patent Application Laid-Open No. 2011-132687 is provided by connecting an adjustment mechanism for adjusting the protruding amount of the closing member to the support member, and the operating portion includes a first cam member, a second cam member, The second cam member is linearly moved by rotating the first cam member, and the support member connected to the second cam member is configured to be able to advance and retract in the protruding direction. Was.

  However, in this sliding door gap closing device, not only the number of parts is large and the structure is complicated, but also the mounting work to the neutral member is difficult. However, there is a problem that the gap closing effect is reduced due to the unexpected rotation and the protruding amount of the closing member being changed.

Object of the invention

  SUMMARY OF THE INVENTION An object of the present invention is to provide a gap closing device for a sliding door that is simple in structure and easy to install and can maintain the gap closing effect without being distorted by an impact.

Means for solving the problem

  The sliding door gap closing device according to the present invention is configured such that a supporting member for a closing member such as a filler can be moved forward and backward with respect to a protruding direction in a housing portion formed along the longitudinal direction of a vertical A such as a vertical fence or a pillar material. In the gap closing device for the sliding door B which is accommodated and adjusts the protruding amount of the closing member connected to the supporting member, the operation gear is engaged with the rotating gear which is pivotally supported in the casing. A sliding screw that is screwed into a screw hole formed in the central portion of the rotating operation gear is connected to a support member of a closing member such as the filler.

Effect of the invention

  In the sliding door gap closing device according to the present invention, when the operating gear rotates in the front-rear direction, the sliding screw connected to the supporting member of the closing member moves left and right by the rotation of the operating gear meshing with the operating gear. The gap between the standing member and the sliding door is closed.

  FIG. 1 is a perspective view of a closing operation tool constituting a gap closing device for a sliding door according to the present invention, FIG. 2 is a longitudinal side view of FIG. 1, and FIG. FIG. 4 is an enlarged cross-sectional view showing a method of attaching the sliding screw to the closing operation tool, FIG. 5 is an enlarged cross-sectional view showing the mounting state of the sliding screw, and FIG. FIG. 7 is a schematic perspective view showing the relationship between the vertical, the wall, and the sliding door.

  1 and 2, reference numeral 1 denotes a closing operation tool constituting a gap closing device for a sliding door according to the present invention, wherein an operation gear 2 is pivotally supported by a shaft 2-1 in a casing 1-1. 3, the screw 4 is screwed into the screw hole 3-1 at the center of the operating gear 3 that meshes with the gear.

  As shown in FIGS. 4 and 5, the screw hole 3-1 at the center of the operating gear 3 has a mortar shape, that is, a countersunk shape so that the screw 4 can be easily screwed together, and the tip of the screw 4 has a truncated cone shape. Therefore, the screw 4 is quickly screwed as shown in FIG. 5 only by rotating the operation gear 3 by rotating the operation gear 2 by applying the screw 4 to the countersunk hole portion.

  Reference numeral 5 denotes a connecting member formed integrally with the screw 4 and is fitted and locked to a long support member 6-1 of a closing member 6 such as a filler.

  Explaining the mounting method and operating state of the sliding door of the present invention, first, the closing operation tool 1 is fitted in the hole formed in the vertical A, and the tip of the screw 4 connected to the support member 6-1 is shown in FIG. When the operation gear 2 is rotated by inserting in the direction of the arrow, the operating gear 3 rotates and the screw 4 is screwed into the screw hole 3-1, as shown in FIG. Therefore, an optimal protrusion amount of the closing member 6 may be selected.

  As described above, the closing operation tool 1 can be easily attached to the vertical A by simply screwing the screw 4.

Effect of the invention

  According to the sliding door gap closing device according to the present invention, the sliding screw connected to the supporting member of the closing member moves to the left and right by rotating the operating gear meshing with the operating gear by rotating the operating gear in the front-rear direction. Since the gap between the neutral member and the sliding door is closed, the number of parts is smaller than that of the conventional product, and the structure is very simple but easy to attach to the neutral member. Yes, even when a very large impact is applied when opening and closing the sliding door, the operating member does not rotate unexpectedly as in the conventional device, and the protruding amount of the closing member does not change and the gap closing effect does not deteriorate It is.

  It is a perspective view of the closing operation tool which constitutes the gap closing device of the sliding door of the present invention.   It is a vertical side view of FIG.   It is a perspective view showing an attachment state to the direction of an apparatus.   It is an expanded sectional view which shows the attachment method of the sliding screw to a closure operation tool.   It is an expanded sectional view showing the mounting state of the sliding screw.   It is a perspective view of the attachment state to the vertical of the apparatus.   It is a schematic perspective view showing the relationship between a vertical, a wall, and a sliding door.
