Description

  The present invention relates to a door connecting mechanism that connects a door plate and a door frame.

  Conventionally, as a door opening / closing method, a mechanism called an in-slide door that can omit a space when the door is opened is known.

  In this in-slide door system, when the door is operated toward the front side or the back side, a slidable guide provided at the upper end of the door fixes the door guide rail to the door. It slides toward the side edge portion. At this time, the connecting mechanism that connects the door plate of the door and the door frame can be rotated at a fixed portion with respect to the door frame, and can also be rotated at the door plate. And changes from the original closed state to a state rotated about 90 degrees.

  In addition, since the guide part is provided rotatably at the upper end of the door plate, the door plate rotates while changing the angle while sliding in the guide rail. Since the opening operation is performed in this way, in the in-slide door system, the door plate rotates and opens at the position where the guide portion is attached, so that the length from the opening shaft side to the guide portion is long. It is possible to save space when opened by an amount equivalent to this.

Japanese Patent Laid-Open No. 11-05073

  However, in the above-described in-slide door, the door may be tilted upward or downward depending on how the force is applied when the door is closed. That is, it is an embodiment as shown in the drawings of FIGS. 6-1 and 6-2.

  FIG. 6A shows a state where force is applied to the upper end side when the door knob is operated. In this case, the door plate 200 is unfolded from the state in which the door connecting mechanism 140 provided on the upper end side is folded before the door connecting mechanism 140 provided on the lower end side, and the guide portion 30 on the upper end side is advanced. As a result, the door is not smoothly closed.

  Moreover, in FIG. 6-2, when operating a doorknob, it is a state when force is applied to the lower end side and is applied. In this case, the guide part 30 provided on the lower end side of the door plate 200 slides first.

  In view of the above, an object of the present invention is to provide a door coupling mechanism that can smoothly perform a door closing operation when opening a door plate of an in-slide type door.

  The object of the present invention is, according to the configuration of the present invention, a door connecting mechanism for connecting a door frame and a door plate, a fixed portion fixed on one side of the door frame, and extending from the fixed portion. A connecting portion that is installed and coupled to the door plate, and is capable of rotating at the joint portion of the fixing portion and the door plate, and an elastic deformation portion provided at the joint portion of the fixing portion. And a restraining portion provided at a position that comes into contact with the elastic deformation portion when the door plate is opened in the fixing portion, and the door plate has an upper end and a lower end of the door plate during the opening operation. The guide member capable of rotating with respect to the door plate is slid within a guide rail of the door plate to perform an opening operation, and when the door plate is opened, the connecting portion But The elastically deforming portion and the restraining portion come into contact with each other in the middle of the rotation operation in the opening direction around the coupling portion, and the restraining portion presses the elastic deforming portion, so that the elastic deforming portion is deformed. However, when the door plate moves to an open position and closes the door plate, the coupling portion is connected by the restoring force of the elastic deformation portion in contact with the suppressing portion to return to the original shape. Rotational motion at the site is achieved by a door coupling mechanism biased in the closing direction.

  According to the above configuration, the opening operation is performed while the elastic deformation portion is deformed by the elastic deformation portion provided in the connecting portion coming into contact with the suppressing portion during the door opening operation. At this time, although the opening operation receives a slight load due to the resistance force related to the deformation of the elastically deforming portion, the opening operation is not hindered, and thus the door plate normally moves to the opening position.

  On the other hand, when the door is closed, the elastically deforming portion is moved from the elastically deformed state in contact with the restraining portion in both the upper and lower door connecting mechanisms. Therefore, since the elastic deformation portion is urged from the suppressing portion by the restoring force, the connection portions of the upper and lower door connection mechanisms are urged to rotate in the closing direction. By doing so, since the rotation of the connecting portion is performed smoothly, the guide portion slides up and down without being biased either way, and the closing operation of the door plate is performed smoothly.

  In the sliding door closing operation suppressing structure according to the present invention, preferably, the elastically deforming portion is a torsion spring having a hole portion on an inside thereof, and a fixing screw is inserted into the hole portion at the coupling portion, and the connection is performed. And fixed to the fixed portion.

  In the sliding door closing operation suppressing structure according to the present invention, preferably, the suppressing member is a protruding portion provided on a locus during the opening operation of the elastic deformation portion in the fixing portion.

    DESCRIPTION OF EXEMPLARY EMBODIMENTS Embodiments that realize the invention will be described below with reference to the drawings. FIG. 1-1 is a schematic front view of a door provided with a door coupling mechanism. Moreover, FIG. 1-2 is the schematic diagram seen from the upper direction of the doorplate in which the door connection mechanism was provided.

As shown in FIGS. 1-1 and 1-2, the door 1 is an in-slide type door, and includes a door frame 10, a guide rail 11, a fixed hinge 12, a door plate 20, a knob 21, a guide portion 30, and a door. A coupling mechanism 40 is provided. The guide rail 11 is provided on the upper end and lower end side of the door frame 10 over its entire length in the longitudinal direction, and is formed of a material such as a U-shaped metal, for example. The fixed hinge 12 is provided at a substantially vertical center position on the side edge of the door plate 20, connects the door frame 10 and the door plate 20, and holds the door plate 20 so that the door plate 20 can be opened and closed.

  The guide part 30 is provided in both the upper and lower end parts of the door plate 20 and is configured to be slidable in the guide rail 11. Moreover, the guide part 30 is rotatable in the site | part in which the doorplate 20 was provided. That is, when the guide portion 30 slides in the guide rail 11, the guide portion 30 itself does not rotate, but the door plate 20 rotates as it slides, and from the state horizontal to the door frame 10, It changes to the state rotated 90 degrees.

  The door coupling mechanism 40 is provided on both the upper and lower ends of the door plate 20, and one end thereof is fixed to the right door plate 20 in the drawing, and the other end is fixed to the upper and lower ends of the door plate 20. Yes. In addition, although the position where the door connection mechanism 40 is fixed to the door plate 20 can be changed as appropriate, it is possible to save the space on the front side of the door when the door is open. Therefore, it is preferable to adjust so that the desired open state of the door can be realized.

  FIGS. 2-1 and 2-2 show a case where the door plate 20 is in an open state. The closing operation of the door 1 is started from this open state. In this state, the door coupling mechanism 40 is in a state of being rotated approximately 90 degrees from the position of the closed state around the portion fixed to the door plate 20.

  Next, a detailed configuration of the door coupling mechanism 40 will be described. As shown in FIG. 3, the door coupling mechanism 40 is configured by two parts, a fixing part 41 and a coupling part 42. The fixing part 41 is a member fixed to the door plate 20, has a bracket shape as shown in FIG. 4A, and is fixed to the door frame 10 by fixing screws 41b.

  The connecting portion 42 connects the fixed portion 41 and the door plate 20, and is provided so as to be rotatable with respect to both the fixed portion 41 and the door plate 20. The connecting portion 42 is fixed to the fixing portion 41 at the coupling portion 44, and is fixed by the rotating shaft 43 that penetrates the hole portion formed in the coupling portion 44 and the hole portion formed in the fixing portion 41. Is done. Therefore, the connecting portion 42 can rotate around the coupling portion 44.

  Further, the connecting portion 42 is fixed to the door plate 20 via a mediating member 46. The mediating member 46 is fixed to the door plate 20 by a pair of screws 46b, and is coupled to the connecting portion 42 via a rotating shaft 46b. Therefore, the connecting portion 42 can rotate around the rotation shaft 46 b in the mediating member 46 fixed to the door plate 20.

  The connecting portion 42 is provided with a torsion spring 45, which is an elastically deformable member, at a position close to the fixing portion 41. The upper surface side of the torsion spring 45 is covered with a spring cover 45d. The spring cover 45 is, for example, a cover made of resin or plastic, and the inside thereof is hollow, and the torsion spring 45 can be deformed in the cover.

  The torsion spring 45 is a spring formed by winding an elastic material many times in a coil shape, and includes a coiled portion 45b and an extending portion 45a extending from the coiled portion 45b. The fixing screw 45c is inserted into the coiled portion 45b and fixed to the connecting portion 42.

  The torsion spring 45 changes with the movement of the connecting portion 42 in accordance with the opening operation of the door, and comes into contact with the protruding portion 41a which is a suppressing portion formed in the fixing portion 41 during the opening operation. The protruding portion 41 a is provided on the rotation locus of the torsion spring 45 in the fixed portion 41. When the torsion spring 45 comes into contact with the protruding portion 41a in the middle of the opening operation, the extended portion 45a is elastically deformed by the force received from the protruding portion 41a. At this time, since the torsion spring 45 is not set to have an elastic force that hinders the opening operation, the user can feel a slight resistance force during the opening operation, but the opening operation is performed smoothly. Once the torsion spring 45 comes into contact with the protruding portion 41a, the closing operation is performed again from the open state, and the torsion spring is moved until the door plate 20 is moved to a position where the torsion spring 45 and the protruding portion 41a do not contact each other. The elastic restoring force is generated in 45.

  Next, the operation of the door coupling mechanism 40 configured as described above will be described with reference to FIGS. FIG. 5A shows a closed state of the door. In this state, the door plate 20 is in a horizontal state with respect to the door frame, and the torsion spring 45 of the door coupling mechanism 40 is also in contact with the protruding portion 41a. Not.

  FIG. 5-2 shows a state in which the contact state with the protrusion 41a of the torsion spring 45 is switched during the operation from the closed state to the open state of the door 1 or during the movement from the open state to the closed state. Yes. In this state, the torsion spring 45 has a restoring force to return to the original state due to elasticity. The timing at which the torsion spring 45 and the protrusion 41a come into contact with each other can be changed as appropriate depending on the shape of the protrusion 41a and the shape of the torsion spring 45, but the length of the door coupling mechanism 40, that is, the saving of the door. What is necessary is just to adjust suitably according to the some space to plan space-ization.

  FIG. 5C shows the door coupling mechanism 40 in the door open state. In this state, the torsion spring 45 and the protrusion 41a are always in contact with each other, so that the restoring force of the torsion spring 45 is always working. Here, the restoring force of the torsion spring 45 is set so as not to move the door plate 20 with respect to the weight of the door plate 20 so that the door plate 20 is not automatically closed by the restoring force of the torsion spring 45. It is desirable that

  In the door connecting mechanism 40 of the present embodiment shown above, when the door plate 20 is operated from the open state to the closed state, the door plate 20 is connected to any connecting portion 42 at the upper and lower ends of the door plate 20 from the start of the operation. Thus, the restoring force by the torsion spring 45 acts, and the force that urges the door plate 20 in the opening direction is acting. Therefore, even if the force is applied to either the upper or lower end, the restoring force acts as a role for assisting the closing operation of the door plate 20, and as a result, the other door connecting mechanism 40 operates normally. Without such a situation, it is possible to avoid a state in which the closing operation is performed with a bias on one side. Therefore, the closing operation of the door plate 20 can be performed smoothly.

The present invention can be implemented in various forms without departing from the spirit of the present invention.
For example, in the above-described embodiment, the configuration using a torsion spring as the elastic deformation portion is used. However, this configuration may be any configuration as long as the door plate 20 can be urged in the opening direction when the door is open. It can also be formed of a spring or an elastic material.

  Further, the shape of the protruding portion can be changed as appropriate, and for example, the door plate 20 itself can be brought into contact with the elastically deforming portion so as to function as a suppressing portion.
