Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a stopper and a fitting for preventing a screen door, a shoji, or the like slidable along a rail of a frame from coming off the rail.

  2. Description of the Related Art Conventionally, as a stopper, there is known an anti-swaying device including a steadying device main body in which a sliding piece is pivotably pivoted and a stopper fixed to the steadying device main body by a fastening screw. (See Patent Document 1). This steady rest is attached to the end of the upper frame of the screen door configured as a door body, and prevents the stopper from hitting the upper rail of the window frame and coming off when the screen door floats. The vertical position of the stopper can be adjusted by loosening the fastening screw.

  The sliding piece is disposed between the pair of side plates of the steady rest body. A shaft projection is formed on the sliding piece to be supported by the pair of side plates, and a torsion spring is wound around the shaft projection. The torsion spring has one end in contact with a spring receiving portion formed in the steady rest body, and the other end in contact with the sliding piece, and elastically biases the sliding piece toward the upper rail. I have. A sliding groove that fits into the upper rail is formed at a sliding fitting end of the sliding piece that protrudes from between the pair of side plates. Since the sliding piece is pressed against the upper rail by the elastic bias of the torsion spring, frictional resistance against sliding of the screen door is generated.

Japanese Patent No. 3303072

  Screen doors are generally constructed by laying a net in a frame consisting of an upper frame, a lower frame and left and right vertical frames, and a lower rail groove formed in the lower frame has a lower rail of a window frame. The upper rail of the window frame is disposed in the upper rail groove formed in the upper frame. First, the screen door is tilted obliquely and the upper rail is placed in the upper rail groove, then the screen door is set up vertically and positioned above the lower rail, and then the screen door is lowered and the lower rail is inserted into the lower rail groove. Is hanged on the window frame.

  By the way, in consideration of warpage that may occur in the upper and lower frames of the window frame, there is a case where a configuration is adopted in which the margin of the lower frame and the lower rail is increased and the screen door does not easily come off the window frame. As described above, when the margin between the lower frame and the lower rail is increased, it is necessary to insert the upper rail deeply into the upper rail groove when hanging the screen door to the window frame.

  However, in the steady rest described in Patent Literature 1, when the sliding piece is in a pivoting state in which the sliding piece is fully inclined against the elastic bias of the torsion spring, the sliding piece is positioned along the upper surface of the spring receiving portion. I do. In this state, even if an attempt is made to insert the upper rail deeply into the upper rail groove, the amount of insertion is restricted by the sliding piece that hits the upper rail. For this reason, it is difficult to hang the screen door on the window frame by positioning the screen door above the lower rail.

  An object of the present invention is to provide a detachment stopper and a fitting that can be configured to be able to hang a door body even when the allowance between the door body and a lower rail is increased.

  The stopper according to the present invention includes a contact arm that contacts the lower end of the upper rail of the upper frame, a spring member that elastically biases the contact arm toward the upper rail, the contact arm and the spring member. A main body member that supports the contact arm, the main body member rotatably supporting the contact arm, and a spring receiver that receives one end of the spring member between the pair of shaft supports. The contact arm includes an arm body, a head that can contact the upper rail, and an arm-side spring receiving portion that receives the other end of the spring member. In the invention, a slit located on a rotation locus of the arm body is formed between one of the pair of shaft supports and the spring receiving portion.

  According to the detachment stopper of the present invention, a part of the arm main body can be arranged in the slit when the contact arm in which the head portion is located below (rotated state), so that the entire contact arm is in the spring receiving portion. As compared with the case where the contact arm is arranged along the upper surface, the position of the contact arm in the coming-off stopper can be lowered while maintaining the strength of the contact arm without reducing the width of the contact arm. For this reason, the upper rail can be inserted into the door body by an amount corresponding to the lowered position of the contact arm, and the door body can be hung on the frame even if the allowance between the door body and the lower rail is increased. .

In the come-off stopper of the present invention, the lower surface of the portion of the arm main body portion that is arranged in the slit is flush with the lower surface of the spring receiving portion that is opposite to the receiving surface that receives the spring member. Preferably, it is positionable.
According to such a configuration, the width from the lower surface to the upper surface of the arm body can be formed as large as possible in the rotating state of the contact arm in which the head is located below, and the strength of the arm body is maintained. it can.

In the stopper according to the aspect of the invention, the contact arm has a shaft portion that is supported by the pair of shaft support pieces, and the spring receiving portion and the arm-side spring receiving portion are arranged with respect to the arm main body. And the spring member is wound around a portion of the shaft portion protruding from the arm body to the other shaft support side. It is preferable to be constituted by a torsion spring.
According to such a configuration, the spring stopper, the arm-side spring receiver, and the torsion spring are arranged closer to the other shaft support side than the arm body, so that the stopper can be made compact.

In the stopper according to the present invention, it is preferable that the arm body has an upward rotation restricting surface that abuts on the spring receiving portion so as to restrict the upward rotation of the head.
According to such a configuration, the upward rotation of the contact arm can be restricted by the contact of the upper rotation restricting surface with the spring receiving portion, and the rotation state of the contact arm with the head portion located above ( The inclination angle of the contact arm with respect to the main body member in the upright state) can be set. For this reason, for example, at the time of suspension, it is possible to set an inclination angle at which the head portion abuts on the upper rail and the contact arm is likely to pivot downward.

In the stopper according to the aspect of the invention, it is preferable that the arm main body has a downward rotation restricting surface that contacts the spring receiving portion so as to restrict the downward rotation of the head.
According to such a configuration, the downward rotation of the contact arm can be restricted by the contact of the downward rotation restricting surface with the spring receiving portion, and the rotational state of the contact arm in which the head portion is located below. It is possible to prevent a force that rotates further downward (in a falling state) from being applied to the upper frame of the door body.

In the stopper according to the present invention, in the main body member, a split groove in which the upper rail of the upper frame is arranged is formed, and the position of the slit in the width direction of the main body member is the split groove in the same width direction. Is preferably arranged so as to overlap the position.
According to such a configuration, a load applied to the contact arm in a state where the head portion is pressed against the lower end of the upper rail disposed in the split groove can be efficiently received in a portion where the width dimension of the arm body portion is large. .

In the stopper according to the present invention, the head portion has a contact inclined surface inclined with respect to the vertical direction and the width direction of the main body member, and the arm main body portion has the same contact inclined surface as the contact inclined surface. A guide inclined surface inclined in the direction is formed, and the guide inclined surface contacts the side edge of the spring receiving portion in a state where the contact arm is shifted toward the other one of the pair of shaft supports. It is preferable to be arranged at a position where it can be touched.
According to such a configuration, when the contact inclined surface is pressed against the lower end of the upper rail, a moving force is generated in the contact arm toward the other shaft support piece, and the arm-side spring receiving portion and the other shaft support. Even if the abutment arm moves by a distance corresponding to the clearance and is positioned to one side of the other axle support, the inclined guide surface abuts against the side edge of the spring receiving portion and the abutment arm moves to the one axle support. I can guide you. Accordingly, it is possible to suppress the contact arm from being offset toward the other shaft support side.

  The fitting of the present invention includes an upper frame, a lower frame and a left and right vertical frame, and a door body disposed in the frame, wherein the upper frame has an upper rail formed therein, A lower rail is formed on the frame, and the door body is configured by assembling an upper frame, a lower frame, left and right vertical frames, and face materials, and the upper frame is provided with the upper rail. A groove is formed, a lower groove in which the lower rail is disposed is formed in the lower frame, and the above-described stopper of the present invention is attached to upper ends of the left and right vertical frames. Features.

  According to the fitting of the present invention, it is possible to configure a fitting that can exhibit the function and effect of the above-described stopper.

  Advantageous Effects of Invention According to the present invention, it is possible to provide a detachment stopper and a fitting that can be configured to be able to hang a door body even if the allowance between the door body and the lower rail is increased.

And a regulation part 123 formed on the upper part of the main body. An elongated hole 124 is formed between the slide pieces 121A and 121B along the vertical direction.

The door stop part 122 is formed so as to protrude toward the front side of the slide member 12 in the lateral direction more than the slide pieces 121A and 121B and the restriction part 123.
The regulating portion 123 is formed by an upper piece that connects the upper ends of the slide pieces 121A and 121B, and the lower end of the upper rail 213 is configured to be able to abut on the upper surface of the upper piece.

The slide member 12 is fixed to the front surface of the main body base 111 by inserting the adjustment screw 60 into the elongated hole 124 and pressing the head of the adjustment screw 60 against the front surfaces of the slide pieces 121A and 121B.
The slide member 12 can be slid up and down with the adjustment screw 60 loosened. FIG. 5A shows a state in which the restricting portion 123 is disposed below the split groove 110, and by sliding the slide member 12 upward from this state, the restricting portion 123 is moved to the groove depth of the split groove 110. The position can be arranged at a position overlapping the split groove 110 (a position indicated by a two-dot chain line in FIG. 5A) so as to regulate the height.

  As shown in FIGS. 5A and 5B, the contact arm 14 includes a head portion 141 capable of contacting the lower end of the upper rail 213, and an arm body portion 142 in which the head portion 141 is continuous with the distal end portion. And a shaft portion 143 connected to the base end of the arm body 142 and a plate-shaped spring receiving portion 144 (arm-side spring receiving portion) connected to the head portion 141 and the arm body 142. The shaft portion 143 is inserted into the shaft holes 113A and 114A to be supported by the shaft.

[Steps for hanging the screen door]
Hereinafter, a procedure for hanging the screen door 5 into the window frame 2 will be described.
The outline of the hanging procedure is as follows. First, the screen door 5 is inclined obliquely with respect to the vertical direction, the upper rail 213 is disposed in the upper groove 511, and then the screen door 5 is set upright to be positioned above the lower rail 223, and then the screen door 5 is lowered. By placing the lower rail 223 in the lower groove 521 and placing the door roller of the door roller device 55 on the lower rail 223, the screen door 5 is suspended in the window frame 2 in a Kendon manner.

  The contact arm 14 of the stopper 10 is in the raised state shown in FIGS. 6A and 7A when the screen door 5 is not suspended. In this rising state, the upper rotation restricting surface 142B is in contact with the upper surface of the spring receiving portion 115, and by this contact, the inclination angle of the contact arm 14 with respect to the lateral direction is set to the set angle (50 ° in the present embodiment). I keep it.

  The upper rail 213 is disposed in the split groove 110 of the stopper 10 when the upper rail 213 is disposed in the upper groove 511, and the lower end of the upper rail 213 contacts the head 141 of the contact arm 14. When the screen door 5 is further lifted in this state, the contact arm 14 rotates downward while being pushed down by the upper rail 213 against the elastic bias of the torsion spring 15. At this time, the lower end of the upper rail 213 is pressed against the contact inclined surface 141A, so that the contact arm 14 is moved toward the shaft support 114 by the clearance between the spring receiving portion 144 and the shaft support 114. However, the guide inclined surface 142D contacts the side edge of the spring receiving portion 115 to restrict the movement. When the contact arm 14 is further rotated downward, the contact arm 14 is guided toward the shaft support piece 113 by the guide inclined surface 142D while the rib 142A is being inserted into the slit 16, and along the shaft support piece 113. Returned to the predetermined position.

  Here, when the screen door 5 is further lifted and the upper rail 213 is inserted into the split groove 110 to the maximum depth as far as possible, the contact arm 14 is further pivoted downward to obtain the state shown in FIGS. 7 (B). In this folded state, the rib 142A of the arm body 142 is accommodated and arranged in the slit 16, the lower rotation regulating surface 142C contacts the upper surface of the spring receiving portion 115, and the contact arm 14 is further rotated downward. regulate. At this time, the surface facing the upper frame 51 of the rib 142A constitutes the lower surface of the arm body 142, and this lower surface is arranged flush with the lower surface of the spring receiving portion 115.

  When the screen door 5 is erected vertically and lowered, the upper rail 213 tends to move upward with respect to the contact arm 14, but the contact arm 14 is turned upward by the elastic bias of the torsion spring 15. The upper rail 213 moves to maintain a state of being pressed against the lower end of the upper rail 213. Due to this pressure contact, the stopper 10 generates frictional resistance against sliding of the screen door 5. Since the position of the screen door 5 is maintained to some extent by the frictional resistance described above, it is possible to prevent the screen door 5 from sliding unintentionally.

After the screen door 5 is suspended, the sliding member 12 is slid upward to arrange the regulating portion 123 at a position overlapping the split groove 110, so that the screen door 5 can be prevented from rising.
When the screen door 5 is to be removed from the window frame 2, the slide member 12 is first slid downward to dispose the regulating portion 123 below the split groove 110. Next, the screen door 5 is lifted to remove the lower rail 223 from the lower groove 521. Subsequently, the screen door 5 is tilted obliquely with respect to the up-down direction and lowered downward, and the upper rail 213 is removed from the upper groove 511. Thus, the screen door 5 is removed from the window frame 2.

[Effects of the present embodiment]
(1) In this embodiment, the stopper 10 comes into contact with the contact arm 14 that contacts the lower end of the upper rail 213, the torsion spring 15 that elastically biases the contact arm 14 toward the upper rail 213, and the contact. A main body member 11 for supporting the arm 14 and the torsion spring 15 is provided. The main body member 11 is provided between a pair of shaft support pieces 113 and 114 for rotatably supporting the contact arm 14. The contact arm 14 has an arm body 142, a head 141 capable of contacting the upper rail 213, and the other end of the torsion spring 15. The main body member 11 has a slit 16 formed on the rotation locus of the arm main body 142 between the shaft support 113 and the spring receiving portion 115. .
With the above configuration, the rib 142A of the arm main body 142 can be arranged in the slit 16 when the contact arm 14 is in a leaning state, so that the entire contact arm 14 is arranged along the upper surface of the spring receiving portion 115. The position of the contact arm 14 in the stopper 10 can be lowered while maintaining the strength of the contact arm 14 without reducing the width of the contact arm 14 (the vertical dimension in the falling state). For this reason, the upper rail 213 can be inserted to the depth of the split groove 110 by the amount by which the position of the contact arm 14 is lowered, and the screen door 5 can be inserted even if the allowance between the lower frame 52 and the lower rail 223 is increased. It can be hung on the window frame 2.
Further, in the present embodiment, the following effects can be exhibited.
(2) The lower surface of the rib 142A arranged in the slit 16 of the arm body portion 142 can be arranged flush with the lower surface of the spring receiving portion 115 located on the side opposite to the receiving surface for receiving the torsion spring 15. .
For this reason, the width from the lower surface to the upper surface of the arm body 142 can be formed as large as possible when the contact arm 14 in which the head 141 is located below is rotated, and the strength of the arm body 142 can be maintained. .
(3) The contact arm 14 has a shaft portion 143 that is supported by a pair of shaft support pieces 113 and 114, and the spring receiving portions 115 and 144 are on the shaft support piece 114 side with respect to the arm main body 142. The torsion spring 15 is wound near a portion of the shaft portion 143 protruding from the arm body 142 toward the shaft support piece 114.
For this reason, by disposing the spring receiving portions 115 and 144 and the torsion spring 15 closer to the shaft support piece 114 side than the arm main body portion 142, the detachment stopper 10 can be made compact.
(4) The arm main body 142 has an upper rotation restricting surface 142B that contacts the spring receiving portion 115 so as to restrict the upward rotation of the head 141.
For this reason, the upward rotation of the contact arm 14 can be restricted by the contact of the upper rotation restricting surface 142B with the spring receiving portion 115, and the main body in the raised state of the contact arm 14 with the head portion 141 positioned above. The inclination angle of the contact arm 14 with respect to the member 11 can be set. Thus, when the screen door 5 is suspended, for example, the head portion 141 can be set to an inclination angle at which the head arm 141 hits the upper rail 213 and the contact arm 14 is likely to pivot downward.
(5) The arm main body 142 is provided with a downward rotation restricting surface 142C that contacts the spring receiving portion 115 so as to restrict the downward rotation of the head portion 141.
For this reason, the downward rotation of the contact arm 14 can be restricted by the downward rotation restricting surface 142 </ b> C abutting on the spring receiving portion 115, and the force of rotating the contact arm 14 further downward when the contact arm 14 is tilted down can be reduced. 5 can be prevented from joining the upper frame 51.
(6) A split groove 110 in which the upper rail 213 is arranged is formed in the main body member 11, and the position of the slit 16 in the width direction W of the main body member 11 overlaps with the position of the split groove 110 in the same width direction W. Are located.
Therefore, a load applied to the contact arm 14 in a state where the head portion 141 is pressed against the lower end of the upper rail 213 disposed in the split groove 110 can be efficiently received in a portion where the width dimension of the arm body portion 142 is large. .
(7) The head portion 141 has a contact inclined surface 141A that is inclined with respect to the up-down direction and the width direction W of the main body member 11, and the arm main body portion 142 is inclined in the same direction as the contact inclined surface 141A. A guide inclined surface 142D is formed, and the guide inclined surface 142D is disposed at a position where the contact arm 14 can be brought into contact with the side edge of the spring receiving portion 115 in a state where the contact arm 14 is shifted to the shaft support piece 114 side.
For this reason, when the contact inclined surface 141 </ b> A is pressed against the lower end of the upper rail 213, a moving force is generated in the contact arm 14 toward the shaft support 114, and the clearance between the spring receiving portion 144 and the shaft support 114 is generated. Even if the contact arm 14 is moved to a position shifted toward the shaft support piece 114, the guide inclined surface 142 </ b> D abuts against the side edge of the spring receiving portion 115 to move the contact arm 14 toward the shaft support piece 113. I can guide you. Accordingly, it is possible to suppress the contact arm 14 from being offset toward the shaft support piece 114 side.
