  The sash as described above, when the inner and outer shojis are closed or when the screen door is moved, the inner door, the outer screen screen and the screen door move toward the vertical frame and come into contact with the vertical frame. A pressing force acts on the vertical frame when it comes into contact with the vertical frame. In particular, since the screen door is lightweight, it may be abutted against the vertical frame vigorously. By repeating such an impact, there is a gap at the joint between the upper frame and the lower frame and the vertical frame. There is a problem that the vertical frame may be generated or the vertical frame may be deformed.

  This invention is made | formed in view of this subject, The place made into the objective is to provide the fitting which can reduce the impact which arises when a shoji is contact | abutted to a vertical frame.

  In order to achieve such an object, the joinery of the present invention includes a shoji that is guided by a frame and is movable in the moving direction, and an opposing frame that constitutes the frame and opposes the door tip of the shoji in the moving direction. One of the door tip portion and the opposing frame includes the door tip portion and the opposing frame when the shoji moves to a predetermined position with respect to the opposing frame. A contact portion that is in contact with the other of the two, and the contact portion absorbs the pressing force when the pressing force is applied to the contact portion by an external force that moves the shoji. It is a fitting characterized by being provided through an elastically deforming portion that is elastically deformed as much as possible.

  According to such a fitting, one of the door tip portion of the shoji and the opposing frame of the frame is opposed to the door tip portion when the door tip portion moves to a predetermined position with respect to the opposing frame. Since the abutting portion that abuts against the other of the frames is provided, the shoji is moved to a predetermined position by abutting the abutting portion against the other of the door tip portion and the opposing frame. It is possible. In addition, when a pressing force that presses the contact portion by an external force that moves the shoji is applied, the contact portion is provided via an elastic deformation portion that elastically deforms to absorb the pressing force. When the contact portion is pressed when the portion reaches a predetermined position, the pressing force is absorbed by the elastic deformation portion, so that the pressing force acting between the door tip portion and the opposing frame is reduced. Is possible. For this reason, it is possible to reduce the impact generated when the shoji is brought into contact with the vertical frame.

In addition , since the contact portion and the elastic deformation portion are arranged at positions adjacent to each other in the direction crossing the movement direction, if a pressing force acts on the contact portion that is allowed to move in the movement direction, the movement direction A moment is generated in which the contact portion rotates in the moving direction with respect to the elastic deformation portion that is restricted from moving toward the center. At this time, the elastically deforming portion located on the opposite side to the contact portion with respect to the center of rotation is elastically deformed by the force acting in the direction opposite to the moving direction due to the generated moment. Can be absorbed.

In this fitting, the abutting portion is fixed to the one of the door tip portion and the opposing frame via the elastic deformation portion, and the pressing portion is deformed when the elastic deformation portion is bent. It is desirable to absorb pressure.
According to such a fitting, since the pressing force can be absorbed by the elastic deformation portion being bent, it can be realized with a simpler structure than when an elastic body such as a spring is used.

In such a joinery, in the direction orthogonal to the moving direction, the distance between the center of the moment and the contact portion is the distance from the center of the moment to a portion where the amount of displacement due to bending is largest in the elastically deforming portion. Shorter is desirable.
According to such a joinery, the distance between the center of the moment and the contact portion is shorter than the distance to the portion where the amount of displacement due to bending is the largest at the center of the moment and the elastic deformation portion in the direction orthogonal to the moving direction. Even if the displacement of the contact portion in the moving direction is small, it is possible to absorb the pressing force by further deforming the elastic deformation portion. For this reason, it is possible to absorb a larger pressing force.

In this joinery, one of the door tip portion and the opposed frame includes a restricting portion that is brought into contact with the contact portion to restrict the position of the shoji, and the door tip portion is It is desirable that the predetermined position with respect to the opposing frame is a position where the contact portion is in contact with the opposing frame and the door tip portion and the opposing frame are parallel to each other.
According to such a joinery, the predetermined position where the contact portion is in contact with the other of the door tip portion and the opposing frame is a position where the door tip portion and the opposing frame are parallel, The pressing force generated when the counter frame is moved in parallel is absorbed by the elastic deformation portion. For this reason, it is possible to make the restoring force by the elastic deformation of an elastic deformation part act so that a shoji and an opposing frame may become parallel.

In this joinery, the frame body includes a guide portion that is provided along the moving direction and guides the shoji, and the shoji moves while sliding while engaging with the guide portion. It is preferable that the abutting portion is provided on the sliding unit.
According to such joinery, since the contact portion is provided in the sliding unit, it is not necessary to attach the contact portion and the sliding unit individually. For this reason, assembly is easy.

  According to the present invention, it is possible to reduce the impact generated when the shoji is brought into contact with the vertical frame.

The inner taper 35j provided on the inner peripheral side is formed to be higher than the outer taper 35k provided on the outer peripheral side.

  The contact portion 35g is provided substantially below half of the thick portion 35i, extends below the thick portion 35i, and is above the outer taper 35k provided on the outer peripheral side of the thick portion 35i. Only the part is connected to the thick part 35i. That is, the contact portion 35g and the elastic deformation portion 35f are arranged at positions adjacent to each other in a substantially vertical direction intersecting the moving direction. The part extended below the thick part 35i of the contact part 35g and the outer peripheral wall part 26d are spaced apart in the direction of finding.

The surface 35m projects from the protrusion 27b and the fitting groove 27d to the outer peripheral side from the protrusion 27b. The abutting surface 35m is provided below the upper end of the outer taper 35k, and the abutting taper is such that the upper side of the abutting surface 35m of the abutting portion 35g becomes narrower in the direction of finding. A portion 35n is provided.

  As shown in FIG. 4, the screen door 20 is moved to the left and right end sides of the frame body 10, and the position in the vertical direction of the door wheel 31 included in the door wheel unit 30 provided at the left and right lower ends is adjusted. Further, the screen door is positioned so that the regulating portion 33 of the door unit 30 and the abutting surface 35m of the sliding unit 35 abut against the engaging portion 13a of the vertical frame 13 in a state where the elastic deformation portion 35f is not deformed. Adjusted. When the position of the door 31 of the screen door 20 is adjusted, the screen door 20 and the left and right vertical frames 13 are parallel to each other.

  By the way, shojis such as screen doors are inserted into the upper frame by moving the shoji screen upward from the indoor or outdoor side, with the upper side tilted in the prospective direction so that it is located behind the lower side. After that, after moving the lower side to the back side and the shoji is in a substantially vertical state, it is often attached to the frame body by the so-called “kendo” method, which is placed on the rail of the lower frame. For this reason, a gap is often provided between the upper part of the shoji and the frame.

  When such a shoji is moved along the frame, a hand is placed on the downspout located on the front side in the traveling direction, and the downspout is pressed and moved by applying an external force in the traveling direction. . At this time, a moment acts on the shoji around the door wheel located on the front side in the traveling direction. That is, the shoji may be tilted so that the upper end side precedes the lower end side of the shoji. In particular, in the case of a screen door having a small weight, the tendency of the screen door to tilt becomes remarkable.

  Then, when the screen door is tilted and moved so that the upper end side precedes the lower end side of the screen door and engages with the vertical hook engaging portion, the restriction portion of the door unit that should contact the engaging portion almost simultaneously. Of the contact surfaces of the sliding unit, the contact surface comes into contact first. At this time, in the case of a conventional screen door in which the restricting portion and the contact portion for adjusting the posture of the screen door are provided with high rigidity in the housing, the engagement portion is provided with the contact surface. A pressing force is applied by the contact. That is, a pressing force acts on the abutting portion 35g by an external force that moves the screen door 20. When the pressing force from such a contact surface repeatedly acts, there is a possibility that a gap is generated between the vertical frame on the front side in the traveling direction and the upper frame, or the vertical frame is deformed.

  Therefore, the fitting 1 of the present application is interposed between the abutting portion 35g (the abutting surface 35m) provided on the screen door 20 as a shoji and the sliding unit fitting portion 35d fitted to the housing 21. The movement of the elastically deforming portion 35f is restricted to the inner peripheral side, and the movement of the contact portion 35g in the inner peripheral direction is allowed. For this reason, when a pressing force is applied to the engagement portion 13a by the contact of the contact surface 35m, the contact portion 35g is also pressed to the inner peripheral side by the engagement portion 13a, and as shown in FIG. A moment acts on the contact portion 35g and the elastic deformation portion 35f with the upper edge of the inner taper 35j provided on the meat portion 35i as the center O. When a moment acts on the contact portion 35g and the elastic deformation portion 35f, the elastic deformation portion 35f is elastically deformed and bent so that the center in the vertical direction of the deformation portion main body 35l is displaced to the outermost peripheral side and absorbs the pressing force. Is done.

  According to the joinery 1 of the present embodiment, when the screen door 20 moves to a predetermined position with respect to the vertical frame 13, the vertical screen 24 of the screen door 20 that the screen door 20 moves and engages with the vertical frame 13 moves. In addition, since the abutting portion 35g that abuts on the engaging portion 13a of the vertical frame 13 is provided, the abutment portion 35g is abutted against the engaging portion 13a of the vertical frame 13 so that the screen door 20 is fixed to the predetermined portion. It can be moved to a position. In addition, when a pressing force that presses the contact portion 35g is applied by an external force that moves the screen door 20, the contact portion 35g is provided via an elastic deformation portion 35f that elastically deforms to absorb the pressing force. Therefore, when the contact portion 35g is pressed when the vertical rod 24 reaches a predetermined position, the pressing force is absorbed by the elastic deformation portion 35f, so that the vertical rod 24 is interposed between the vertical rod 24 and the vertical frame 13. It is possible to reduce the pressing force acting. For this reason, it is possible to reduce the impact generated when the screen door 20 is brought into contact with the vertical frame 13.

  In addition, since the contact portion 35g and the elastic deformation portion 35f are arranged at positions adjacent to each other in the direction intersecting the movement direction, that is, in the vertical direction, the contact portion 35g is pressed against the contact portion 35g allowed to move in the movement direction. When the pressure is applied, a moment is generated between the elastic deformation portion 35f in which movement in the movement direction is restricted, that is, the contact portion 35g rotates in the movement direction with the upper edge of the inner taper 35j as the center O. . At this time, the deformable portion main body 35l of the elastically deformable portion 35f located on the opposite side to the contact portion 35g with respect to the rotation center O is elastically deformed so as to be bent by a force acting in the direction opposite to the moving direction due to the generated moment. Therefore, it is possible to absorb the pressing force acting on the contact portion 35g.

  The distance L1 between the moment center O and the abutting portion 35g is such that the displacement of the deformable portion main body 35l is the largest in the center of moment O and the elastically deformable portion 35f that bends and deforms in the vertical direction perpendicular to the moving direction. Since it is shorter than the distance L2 from the center, it is possible to absorb the pressing force by further deforming the elastic deformation portion 35f even if the displacement of the contact portion 35g is small in the moving direction. For this reason, it is possible to absorb a larger pressing force.

  The predetermined position where the abutting portion 35g abuts on the engaging portion 13a of the vertical frame 13 is a position where the screen door 20 and the vertical frame 13 are parallel to each other, and therefore the screen door 20 and the vertical frame 13 are parallel to each other. It is possible to absorb the pressing force generated when the position exceeds a certain position, and to apply the restoring force due to the elastic deformation of the elastic deformation portion 35f so that the screen door 20 and the vertical frame 13 are parallel to each other.

  Further, since the deformable portion main body 35l is bent in the elastic deformable portion 35f, it is possible to absorb the pressing force with a simpler structure. In the present embodiment, the example in which the elastic deformation portion 35f and the contact portion 35g are integrally formed has been described. However, the elastic deformation portion and the contact portion, which are formed separately, are joined to each other. It does not matter. In the present embodiment, the example in which the elastic deformation portion 35f is bent and deformed has been described. However, for example, an elastic body such as a spring may be used as the elastic deformation portion.

  The contact portion 35g of this embodiment is integrated with a sliding unit 35 provided with a sliding member 36 that moves while engaging and sliding with a screen door rail 10c provided on the upper frame 11 of the frame 10. Therefore, it is not necessary to attach the contact portion 35g and the sliding member 36 individually. For this reason, assembly is easy. Note that the abutting portion 35g and the sliding member 36 are not necessarily provided integrally. Moreover, the contact part and the elastic deformation part may be formed integrally with the door toe part or the vertical frame of the shoji.

  In the said embodiment, although the screen door 20 was mentioned as an example as a shoji, it was not restricted to this, For example, a glass door etc. may be sufficient. Moreover, although the pull-type joinery 1 has been described as an example, any other shoji that can move along the frame body, such as a single-draw shoji, may be used. Moreover, although the shoji which moves to the left-right direction was mentioned as an example, the moving direction of the shoji may be the up-down direction.

  Moreover, in the said embodiment, when the door tip part engaged with the vertical frame, although the example provided with the contact part and elastic deformation part which absorb an impact on the shoji side was demonstrated, it is provided in the vertical frame side. It does not matter.

  In the said embodiment, although the example which engages when the engaging part 13a which the left and right vertical frames 13 enter in the outer peripheral groove part 27 which the vertical rod 24 of the screen door 20 has was demonstrated, it does not restrict to this. For example, the engagement between the frame body and the door-end portion of the screen door is performed by engaging a fin-like portion provided in a vertical rod into a groove provided in the vertical frame, or on the vertical frame side. A case is also included in which a vertical rod of a door end enters a groove portion that is provided along the vertical direction and is opened toward the inner peripheral side, and engages when the flat portions are brought into contact with each other.

  In addition, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
