Description

Movement restriction devices and doors and windows

The present invention relates to a movement limiting device and door and window for limiting the movement of door and window sashes such as screen doors and windows relative to an edge frame.

In a door and window with door and window sashes, there is a movement limiting device for limiting the movement of the door and window sashes along the track of the edge frame. As such a movement limiting device, there are many movement limiting devices used that have: a snap-fitting member, which is installed on the vertical edge frame constituting the edge frame body and forms a downward L-shape; a receiving member, which is installed on the vertical frame constituting the door and window sash and forms an upward L-shape (for example, refer to patent document 1). In this movement limiting device, for example, when the vertical frame of the door and window sash is abutted against the vertical edge frame of the edge frame body, if the snap-fitting surface of the snap-fitting member and the receiving surface of the receiving member are abutted against each other, the movement of the vertical frame relative to the vertical edge frame in the direction of separation can be limited.

In addition, in the above-mentioned movement restriction device, when the height position where the operating force is applied by a person to the door and window sash is substantially the same as the height position where the buckle member and the receiving member are installed, the contact state between the buckle surface and the receiving surface is maintained when the door and window sash is pulled, thereby restricting the movement of the door and window sash. In contrast, when the height position where the buckle member and the receiving member are installed are misaligned with the height position where the operating force is applied by a person to the door and window sash, when the door and window sash is pulled, the vertical frame of the door and window sash may be tilted relative to the vertical edge frame of the edge frame body. Therefore, in the movement restriction device, there is a concern that the receiving surface of the receiving member installed on the vertical edge frame is tilted relative to the buckle surface of the buckle member installed on the vertical frame. The abutment between the snap-fitting member and the receiving member is maintained by the force exerted on the snap-fitting member and the receiving member by the springs arranged along the extension direction of the longitudinal edge frame and the longitudinal frame. However, when the receiving surface of the receiving member is in an inclined state, the operating force when pulling the door and window sash will generate a force to resist the force of the spring, which may cause the snap-fitting member and the receiving member to move in the direction of separation from each other, resulting in the release of the abutment between them.

In view of the above situation, the present invention aims to provide a movement restriction device and a door and window that can more accurately restrict the movement of the door and window sash relative to the edge frame.

In order to achieve the above-mentioned purpose, the movement restriction device of the present invention comprises: a buckling member, which is installed on one of the edge frame member constituting the edge frame body and the frame member constituting the door and window sash, and the door and window sash is configured to be movable relative to the edge frame body; and a receiving member, which is installed on the other of the edge frame member and the frame member, wherein the buckling surface of the buckling member and the receiving surface of the receiving member are buckled with each other to restrict the movement of the door and window sash relative to the edge frame body, and the buckling member and the receiving member are configured to be movable relative to each other along the front view direction of the edge frame member and the frame member, and the front end side of the buckling surface and the front end side of the receiving surface are respectively provided with a portion protruding toward the matching side relative to the respective base end sides.

In addition, the movement restriction device of the present invention comprises: a fastening member, which is mounted on one of the edge member constituting the edge frame and the frame member constituting the door and window sash, wherein the door and window sash is configured to be movable relative to the edge frame; and a receiving member, which is mounted on the other of the edge member and the frame member, wherein the fastening surface of the fastening member and the receiving surface of the receiving member are fastened to each other to restrict the movement of the door and window sash relative to the edge frame, and the receiving member The buckle member and the receiving member are configured to be relatively movable along the front view direction of the edge member and the frame member. At least one of the front end side of the buckle face and the front end side of the receiving face is provided with a contact surface. The contact surface is inclined relative to the front view direction of the edge member and the frame member in a manner that the front end side gradually protrudes toward the matching side. When the contact surface is in contact with the matching side, the buckle face and the receiving face are buckled with each other.

According to the present invention, when the front end of the engaging surface and the front end of the receiving surface face each other, they engage with each other in a state where their respective base ends protrude toward the mating side. Therefore, even when the frame is tilted relative to the edge frame, the engaging state between the engaging surface and the receiving surface can still be maintained, thereby preventing the door and window sash from moving.

In addition, according to the present invention, since at least one of the front end of the engaging surface and the front end of the receiving surface is inclined in a manner protruding toward the mating side relative to the base end when facing each other, even if the screen door window is inclined relative to the edge frame, the engaging state between the engaging surface and the receiving surface can still be maintained, which can prevent the screen door window from moving inadvertently.

In the door and window having the above-mentioned structure, a movement restriction device 1 is provided between the edge frame body 10 and the screen door and window 30. More specifically, as shown in FIGS. 1 to 5 , the movement restriction device 1 for preventing the screen door and window 30 from moving by itself is constructed between a vertical edge frame (hereinafter referred to as the right edge frame member 13) located on the right side of the edge frame body 10 when viewed from the indoor side and a vertical screen door and window frame (hereinafter referred to as the right frame member 34) located on the right side of the screen door and window 30 when viewed from the indoor side. The structure of the movement restriction device 1 is described below, including the detailed structure of the right edge frame member 13 and the right frame member 34. In addition, in the following description, for convenience, the directions of the components of the movement restriction device 1 are defined in the posture of being installed on the right edge frame member 13 and the right frame member 34.

The right edge member 13 of the edge frame body 10 and the right frame member 34 of the screen door and window 30 are extrusion-molded components formed by metal such as aluminum alloy or resin, and are respectively configured to have approximately the same cross-sectional shape along the entire length along the longitudinal direction (vertical direction). The right edge member 13 has: a flat edge base plate portion 13a, which extends along the depth direction; and a flat front-view edge plate portion 13b, which extends along the front-view direction from the edge portion located on the outdoor side of the edge base plate portion 13a. The position of the front-view edge plate portion 13b in the depth direction is set to be the same as the guide rail 11a for the screen door and window provided on the horizontal edge frame 11, and has a portion protruding from the edge base plate portion 13a to the inner peripheral side. The right frame member 34 has a frame base 34a formed in a hollow cylindrical shape and two front frame plate portions 34b extending from two corner portions located on the outer peripheral side of the frame base 34a to the outer peripheral side. The front frame plate portions 34b are formed with locking surfaces 34c at the portions facing each other. The locking surfaces 34c are formed by providing protrusions on the inner surfaces of the front frame plate portions 34b facing each other, and facing the frame base 34a. As shown in FIG. 2 , in the present embodiment 1, when the guide rail 32a of the screen door and window horizontal frame 32 is engaged with the screen door and window guide rail 11a of the horizontal edge frame 11, the frame base 34a is arranged on the outdoor side of the edge frame plate 13b of the right edge frame member 13 when viewed from the front, so as to form the edge frame body 10 and the screen door and window 30.

As shown in FIGS. 3 to 5 , the movement restriction device 1 is configured to have an operating unit 40 and a latch unit 50. In the present embodiment 1, the operating unit 40 is mounted on the inner peripheral portion of the front-view edge frame plate portion 13b of the right edge frame member 13, and the latch unit 50 is mounted on the portion between the two front-view frame plate portions 34b in the frame base portion 34a of the right frame member 34.

The cover plate portion 41b extends from the approximately central portion in the vertical direction toward the outside of the sliding guide plate portion 41a and in the depth direction, and is formed into a flat plate having a width greater than the dimension of the right frame member 34 in the depth direction. In the present embodiment 1, the sliding guide plate portion 41a and the cover plate portion 41b are connected to each other via the connecting plate portion 41f arranged to bypass the inner peripheral side of the front-view edge plate portion 13b. That is, the connecting plate portion 41f protrudes from the approximately central portion of the edge portion located on the inner peripheral side of the sliding guide plate portion 41a, passes over the front-view edge plate portion 13b, and protrudes toward the outside of the room, and then extends toward the outer peripheral side in a manner that is approximately parallel to the sliding guide plate portion 41a. The cover plate portion 41b extends from the edge of the outer peripheral side of the connecting plate portion 41f to the outside of the room. The edge of the cover plate portion 41b located on the outside of the room is provided with a guide cover plate portion 41g. The guide cover plate portion 41g is inclined relative to the sliding guide plate portion 41a in a manner that the outside gradually becomes the inner peripheral side.

The locking plate portion 41c is formed as a flat plate extending from the approximately middle portion between the sliding guide plate portion 41a and the guide cover plate portion 41g in the cover plate portion 41b to the inner peripheral side, and is arranged to be approximately parallel to the sliding guide plate portion 41a. A lower locking protrusion portion 41h is provided at the extended edge of the locking plate portion 41c, which is arranged to protrude downward.

The lower snap-fitting tab portion 41h is provided in the same flat plate shape as the snap-fitting plate portion 41c, and as shown in FIG12(a), has a snap-fitting guide surface 41j at the edge of the inner peripheral side, and has a snap-fitting surface portion 41k at the edge of the outer peripheral side. The snap-fitting guide surface 41j is inclined relative to the lead vertical direction in a manner that gradually changes to the outer peripheral side toward the lower side. The snap-fitting surface portion 41k is configured to have a snap-fitting surface 41m at the upper portion of the base end side, and a snap-fitting side protrusion 41n at the lower portion closer to the front end side than the snap-fitting surface 41m. In the illustrated example, the snap-fitting surface 41m and the snap-fitting side protrusion 41n are provided by forming a recess in the middle portion of the snap-fitting surface portion 41k. The snap-fitting surface 41m is a plane extending in the depth direction substantially along the lead vertical direction. The buckling side protrusion 41n is formed to protrude toward the outer periphery relative to the buckling surface 41m, and the lower part is bent into an arc shape. The buckling side disengagement guide surface 41p is provided in the upper part of the buckling side protrusion 41n and the portion between the buckling surface 41m. The buckling side disengagement guide surface 41p is a plane inclined relative to the buckling surface 41m in a manner of gradually protruding toward the outer periphery from the lower side. In addition, the extended edge of the buckling plate portion 41c is provided with an upper buckling protrusion portion 41q, which is provided to have a shape symmetrical to the lower buckling protrusion portion 41h and faces upward. When the operating buckle member 41 is set on the longitudinal edge frame 12 located on the left side of the edge frame body 10 when viewed from the indoor side, it is inverted upside down, and the upper buckle protrusion 41q has the function of the lower buckle protrusion 41h described later.

As shown in Figures 6 to 8, the back plate 42 is disposed between the front surface of the front edge plate portion 13b facing the outside and the connecting plate portion 41f of the operating buckle member 41, and is formed into a plate-shaped member having approximately the same upper and lower dimensions as the sliding guide plate portion 41a of the operating buckle member 41. The upper and lower ends of the back plate 42 are respectively provided with screw holes 42a and engaging grooves 42b. The screw holes 42a can be screwed with the shaft 45a of the mounting screw 45 passing through the guide hole 41d of the sliding guide plate portion 41a, and are arranged side by side up and down at approximately the same spacing as the guide hole 41d. The engaging groove 42b is a groove-shaped notch formed along the upper and lower end surfaces of the back plate 42 in the up and down direction.

The operating base 43 is arranged on the front surface of the frame plate portion 13b facing the interior when it covers the sliding guide plate portion 41a of the operating buckle member 41. This operating base 43 is provided with a screw insertion hole 43a and a fitting recess 43b at the upper and lower ends, and an upper locking hook portion 43c is provided at the approximately central portion in the up and down directions. The screw insertion hole 43a is a through hole formed in the shape of a long hole and provided on the portion corresponding to the guide hole 41d of the operating buckle member 41. The fitting recess 43b is a recessed portion, and when the operating base 43 is facing the sliding guide plate portion 41a with the screw insertion hole 43a facing the guide hole 41d, the fitting plate portion 41e of the sliding guide plate portion 41a is fitted therein. The upper locking hook 43c protrudes from the inner peripheral side of the surface of the operating base 43 facing the outside of the room in the depth direction and then bends up and down.

The back plate cover 44 is arranged on the front surface of the edge plate portion 13b facing the outside when it covers the back plate 42 on the inner peripheral side relative to the cover plate portion 41b. The back plate cover 44 is provided with a lower locking hook portion 44a, and a fitting protrusion 44b is provided at both upper and lower ends. The lower locking hook portion 44a protrudes from the inner peripheral side of the surface of the back plate cover 44 facing the room in the depth direction and then bends downward, and is formed at a portion lower than the upper locking hook portion 43c of the operating base 43. When the fitting protrusion 44b is overlapped on the back plate 42, it fits into the fitting groove 42b of the back plate 42, so that the back plate cover 44 is supported by the back plate 42. In addition, the back cover 44 is also provided with a lower locking hook 44a at the upper portion at a position symmetrical to the lower locking hook 44a. The lower locking hook 44a provided at the upper portion is effective when the operation unit 40 is provided on the longitudinal frame 12 located on the left side of the frame body 10 when viewed from the indoor side.

In order to install the operating unit 40 having the above structure to the right edge member 13, two upper and lower screw through holes 13c are formed in advance at the position where the operating unit 40 is installed in the front view edge plate portion 13b. The screw through hole 13c has a size for the shaft 45a of the mounting screw 45 screwed to the screw hole 42a of the back plate 42 to pass through, and is pre-set on the edge of the inner peripheral side of the front view edge plate portion 13b with the same spacing as the screw hole 42a.

For this front-view frame plate portion 13b, first, the back plate 42 is overlapped on its front-view surface facing the outside, and further, in a state where the front-view frame plate portion 13b and the back plate 42 are arranged between the sliding guide plate portion 41a and the connecting plate portion 41f, the operating buckle member 41 is arranged on the right frame member 13. In this state, when the mounting screw 45 is screwed into the screw hole 42a of the back plate 42 through the screw insertion hole 43a of the operating base 43, the guide hole 41d of the sliding guide plate portion 41a and the screw through hole 13c of the front-view frame plate portion 13b, the operating buckle member 41 and the operating base 43 can be installed on the front-view frame plate portion 13b of the right frame member 13. These operating buckle components 41 and operating base 43 can move up and down relative to the mounting screw 45 within the range of the screw insertion hole 43a and the guide hole 41d. In other words, the operating buckle components 41 and the operating base 43 can move up and down relative to the right edge frame component 13. In the present embodiment 1, by interposing a tension coil spring (force applying component) 46 between the lower locking hook 44a of the back plate cover 44 installed on the back plate 42 and the upper locking hook 43c of the operating base 43, the operating buckle components 41 and the operating base 43 are always forced downward by the spring force of the tension coil spring 46. In order to install the back plate cover 44 on the back plate 42, the engaging protrusions 44b can be engaged in the engaging grooves 42b respectively. When the operating unit 40 is installed in the right edge frame member 13 in the above manner, when the screen door window 30 is moved to approach the right edge frame member 13, the locking plate portion 41c is arranged between the two front-view frame plate portions 34b of the right frame member 34.

As shown in Figs. 9 to 11, the receiving member 51 is formed in a block shape of a substantially square column extending in an up-and-down direction, and has a guide pin portion 51a on the side surface located on the indoor side and the side surface located on the outdoor side, and has a spring support pin portion 51b on the lower surface. The guide pin portion 51a is formed in a cylindrical shape extending in the depth direction, and is disposed on the same axis as each other, and protrudes from the side surface on the indoor side and the side surface on the outdoor side. The spring support pin portion 51b is formed in a cylindrical shape extending downward in a substantially vertical direction. In addition, the receiving member 51 is provided with a receiving protrusion 51c on the upper surface. As shown in Figure 12(a), the receiving protrusion 51c protrudes upward from the edge located on the outer peripheral side of the receiving member 51, and has a receiving surface portion 51d on the inner peripheral side. The receiving surface portion 51d is configured to have a receiving surface 51e in the lower portion of the base end side, and a receiving side protrusion 51f in the upper portion closer to the front end side than the receiving surface 51e. The receiving surface 51e is a plane extending in the depth direction along a substantially vertical direction. The receiving side protrusion 51f protrudes toward the inner peripheral side compared to the receiving surface 51e, and is configured to have a protruding dimension that is substantially the same as that of the snap-fitting side protrusion 41n of the snap-fitting plate portion 41c. The receiving side protrusion 51f is provided with an introduction guide surface 51g and a receiving side disengagement guide surface 51h. The introduction guide surface 51g is provided at the upper part of the receiving side protrusion 51f, and is inclined relative to the receiving surface 51e in a manner that it gradually protrudes from the bottom to the inner peripheral side. The receiving side unfastening guide surface 51h is provided at the lower part of the receiving side protrusion 51f between the receiving surface 51e, and is inclined relative to the receiving surface 51e in a manner that it gradually protrudes from the top to the inner peripheral side. In addition, the receiving component 51 of the present embodiment 1 is integrally formed by die-casting using a metal such as an aluminum alloy as a material.

As shown in Figures 9 to 11, the protective cap 52 is a resin component that is set to cover the outer surface of the receiving component 51. In the example shown in the figure, the protective cap 52 is configured to expose the guide pin portion 51a, the spring support pin portion 51b and the receiving surface portion 51d to the outside. The protective cap 52 is provided with a receiving side guide surface 52a on the portion covering the outer peripheral side of the receiving protrusion 51c. The receiving side guide surface 52a is a plane that is inclined relative to the front view direction B of the right frame member 34 in a manner that gradually changes from the upper side to the inner peripheral side.

The latch base 53 accommodates the receiving member 51 with the protective cap 52 mounted thereon in a manner that allows it to move in the up-down direction. In the present embodiment 1, the latch base 53 is configured to include an outer peripheral substrate portion 53a, two side plate portions 53b, two peripheral plate portions 53c, and a bottom plate portion 53d. The outer peripheral substrate portion 53a is formed in a substantially square flat plate shape and extends in the depth direction in the up-down direction. The side plate portion 53b extends from the two side edges of the outer peripheral substrate portion 53a to the inner peripheral side in a manner that is substantially parallel to each other, and the side plate portion 53b and the outer peripheral substrate portion 53a form a storage space for the receiving member 51. The side plate portion 53b of the present embodiment 1 is configured to have a dimension in the up-down direction that is approximately twice that of the peripheral substrate portion 53a, and extends in a manner that protrudes upward from the upper end of the peripheral substrate portion 53a. The distance between the outer surfaces of the two side plate portions 53b is set to be embedded between the two front-view frame plate portions 34b of the right frame member 34. The side plate portion 53b is formed with guide grooves 53e along the upper and lower sides, respectively, and a locking protrusion 53f is formed on each outer surface. The guide groove 53e is formed with a width that can be inserted into the guide pin portion 51a of the receiving component 51, and through cooperation with the guide pin portion 51a, it has the function of guiding the receiving component 51 to move up and down relative to the side plate portion 53b. When the latch base 53 is arranged between the two front-view frame plate portions 34b of the right frame member 34, the locking protrusion 53f abuts against the locking surface 34c provided on the side plate portion 53b. The peripheral plate portion 53c is bent and extended so that they gradually approach each other from the portion below the side plate portion 53b in the outer peripheral substrate portion 53a to the inner peripheral side. When the receiving member 51 is arranged between the side plate portions 53b, it is arranged on a circumference centered on the axis of the spring support pin portion 51b. The bottom plate portion 53d extends approximately horizontally from the lower edge of the outer peripheral substrate portion 53a to the inner peripheral side, then bends approximately straight downward, and has a screw insertion hole 53g in the portion extending downward.

In order to mount the latch unit 50 having the above-mentioned structure on the right frame member 34, the protective cap 52 is mounted on the receiving member 51 in advance and accommodated between the side plate portions 53b of the latch base 53, and the guide pin portions 51a are respectively arranged in the guide grooves 53e, so that it is arranged to be movable in the vertical direction relative to the latch base 53. In the present embodiment 1, the compression coil spring (biasing member) 54 is interposed between the lower surface of the receiving member 51 and the bottom plate portion 53d of the latch base 53, and the receiving member 51 is always biased upward relative to the latch base 53 by the spring force of the compression coil spring 54. The compression coil spring 54 is configured with the spring support pin portion 51b of the receiving member 51 at the upper end, and the lower end is configured between the peripheral plate portion 53c and the outer peripheral base plate portion 53a of the latch base 53, so as to apply force to the receiving member 51 and prevent it from falling off. In this state, the latch base 53 is configured between the two front-view frame plate portions 34b of the right frame member 34, and the mounting screw 55 is further screwed into the frame base portion 34a through the screw insertion hole 53g of the bottom plate portion 53d, so that the latch unit 50 can be installed on the right frame member 34. In this state, the locking protrusion 53f provided on the side plate portion 53b abuts against the locking surface 34c of the side plate portion 53b, and prevents the latch base 53 from moving toward the outer peripheral side relative to the right frame member 34. The position of installing the latch unit 50 is set so that when the screen door window 30 moves and approaches the right edge frame member 13, the latch guide surface 41j of the latch protrusion portion 41h provided below the latch plate portion 41c abuts against the receiving side guide surface 52a of the protective cap 52.

According to the door and window provided with the above-mentioned movement restriction device 1, when the screen door and window 30 is moved toward the right edge frame 13 from the state shown in FIG. 13(a), as shown in FIG. 13(b), the locking guide surface 41j of the locking protruding piece 41h provided below the locking plate portion 41c is in contact with the receiving side guide surface 52a of the protective cap 52. When the screen door and window 30 is further moved toward the right edge frame 13 in this state, as shown in FIG. 13(c), the locking guide surface 41j and the receiving side guide surface 52a are tilted, so that the operating locking member 41 and the receiving member 51 resist the spring force of the tension coil spring 46 and the compression coil spring 54, and appropriately move in the up-down direction and separate from each other. In the present embodiment 1, since the spring constant of the compression coil spring 54 is set to be larger than that of the tension coil spring 46, the operating buckle member 41 of the operating unit 40 moves upward.

When the screen door 30 moves and the abutment state between the fastening guide surface 41j and the receiving side guide surface 52a is released, as shown in FIG13(d), due to the spring force of the tension coil spring 46 and the compression coil spring 54, the operating fastening member 41 and the receiving member 51 move in the direction of approaching each other in the up-down direction, and are in a state where the fastening surface 41k and the receiving surface 51d face each other. During this period, when the operating fastening member 41 and the receiving member 51 move in the direction of approaching each other, as shown in FIG12(b), the fastening side protrusion 41n of the operating fastening member 41 abuts against the introduction guide surface 51g of the receiving member 51. Therefore, the inclination of the guide surface 51g allows the operating buckle member 41 and the receiving member 51 to move appropriately in the horizontal direction in the direction of separation from each other, as shown in FIG. 12(c), so that the buckle side protrusion 41n of the operating buckle member 41 passes over the receiving side protrusion 51f of the receiving member 51 and faces the receiving surface 51e, and the receiving side protrusion 51f of the receiving member 51 faces the buckle surface 41m of the operating buckle member 41. Thus, even if the screen door 30 is tried to be moved to separate it from the right edge frame member 13, the buckle surface 41k of the operating buckle member 41 and the receiving surface 51d of the receiving member 51 still maintain the buckle state, so that the movement of the screen door 30 is restricted.

Here, for example, the movement restriction device 1 is arranged at a height position of about 1/3 of the total height of the right edge frame member 13 and the right frame member 34 from the top. In this state, when an operating force is applied to a height of less than 1/3 from the bottom of the screen door and window vertical frame 33 located on the left side when viewed from the indoor side, in an attempt to move the screen door and window 30 to the left side, the screen door and window 30 rotates clockwise relative to the edge frame body 10 when viewed from the indoor side and is tilted. Therefore, in the movement restriction device 1, as shown in FIG. 12(d), the receiving member 51 provided on the right frame member 34 rotates clockwise relative to the operating engaging member 41 provided on the right edge frame member 13 and tilts. However, in the movement restriction device 1 provided in the above-mentioned door and window, as described above, the engaging side protrusion 41n provided at the front end of the engaging surface 41k and the receiving side protrusion 51f provided at the front end of the receiving surface 51d engage with each other at a position where they cross each other. In other words, when the engaging surface 41k and the receiving surface 51d face each other, they engage with each other in a state where their respective base ends protrude toward the mating side. Therefore, even when the screen door and window 30 is in a tilted posture relative to the edge frame body 10, there is no risk of the operating engaging member 41 and the receiving member 51 moving in a direction of separation from each other along the front view direction B of the right edge frame member 13 and the right frame member 34, and the engaging state of the two is maintained. This can maintain the restricted movement of the screen door and window 30 relative to the edge frame 10, and prevent the screen door and window 30 from moving inadvertently.

Incidentally, in order to move the screen door 30 from the above state, if the operating base 43 is moved upward relative to the right edge frame 13 against the spring force of the tensile coil spring 46, the operating buckle member 41 moves upward relative to the receiving member 51, so that the receiving surface 51d of the receiving member 51 and the buckle surface 41k of the operating buckle member 41 are not facing each other. Therefore, if an operating force is applied to the screen door 30 in this state, the screen door 30 can be moved relative to the edge frame 10.

At this time, according to the above-mentioned movement restriction device 1, as shown in FIG. 12(e), as the operating buckle member 41 moves upward, the buckle side release guide surface 41p provided on the buckle surface 41k and the receiving side release guide surface 51h provided on the receiving surface 51d abut against each other. Therefore, as long as the operating base 43 is moved upward, the buckle side release guide surface 41p and the receiving side release guide surface 51h are tilted, so that the operating buckle member 41 and the receiving member 51 are appropriately moved in the horizontal direction in the direction of separation from each other, and the buckle side protrusion 41n of the operating buckle member 41 passes over the receiving side protrusion 51f of the receiving member 51 and moves upward, so that it becomes easy to operate. As long as the operating force applied to the operating base 43 is removed, the operating buckle member 41 will move downward due to the spring force of the tension coil spring 46. Therefore, as long as the screen door window 30 is moved toward the right edge frame member 13 again, the movement of the screen door window 30 can be restricted.

In addition, although the introduction guide surface 51g is provided only on the receiving member 51 in the above-mentioned embodiment 1, the present invention is not limited thereto, and the introduction guide surface may be provided only on the operating buckle member 41, or may be provided on both the receiving member 51 and the operating buckle member 41. In addition, although the unlocking guide surfaces 41p, 51h are provided on both the operating buckle member 41 and the receiving member 51, the unlocking guide surface may be provided on only one of the operating buckle member 41 and the receiving member 51. However, it is not necessary to provide the introduction guide surface 51g and the unlocking guide surface 41p, 51h. For example, as in the variant 1 shown in FIG. 14 and the variant 2 shown in FIG. 15 , both the introduction guide surface 51g and the unlocking guide surface can be omitted to form a movement restriction device.

That is, in the modification example 1 shown in FIG. 14 , a side interface 141a along the horizontal direction is formed between the side protrusion 41n of the operation buckle member 141 and the buckle surface 41m. Similarly, the side protrusion 51f of the receiving member 151 is formed with side interfaces 151a and 151b along the horizontal direction at the upper and lower parts, respectively. In addition, the same component symbols are marked for the same components in the modification example 1 as those in the implementation example 1.

In addition, in the modification example 2 shown in FIG. 15, a side interface 241a along the horizontal direction is formed between the side protrusion 41n of the operation buckle member 241 and the buckle surface 41m. In addition, the buckle surface 41m is extended to the upper end of the lower buckle protrusion 41h. The receiving side protrusion 51f of the receiving member 251 is directly extended to the upper end of the receiving protrusion 51c, and a side interface 251a along the horizontal direction is formed at its lower part. In addition, the same component symbols are marked for the same configurations in the modification example 2 as those in the implementation type 1.

In doors and windows having the movement limiting device of such variant example 1 or variant example 2, even when the operating locking member 141, 241 and the receiving member 151, 251 move toward each other due to the spring force of the tension coil spring 46 and the compression coil spring 54, it is still possible that the front end of the operating locking member 141, 241 is maintained in abutment with the upper end of the receiving side protrusion 51f or the receiving protrusion 51c, and the locking surface 41k of the operating locking member 141, 241 and the receiving surface 51d of the receiving member 151, 251 are not faced with each other. However, even if the above situation occurs, when the screen door and window 30 is moved further toward the direction approaching the right edge frame member 13 (to the right side of the figure in Figures 14 and 15), as shown in Figures 14(b) and 15(b), the abutment between the front end of the operating buckle component 141, 241 and the upper end of the receiving side protrusion 51f is released, and the operating buckle component 141, 241 and the receiving component 151, 251 move toward each other due to the spring force of the tension coil spring 46 and the compression coil spring 54, so that the buckle surface 41k of the operating buckle component 141, 241 and the receiving surface 51d of the receiving component 151, 251 are facing each other. Therefore, in this state, when the screen door and window 30 is moved to separate from the right edge frame 13, as shown in Figures 14(c) and 15(c), the engaging surface 41k of the operating engaging member 141, 241 and the receiving surface 51d of the receiving member 151, 251 are in an engaged state, which can limit the movement of the screen door and window 30.

Furthermore, in the engaged state between the engaging surface 41k of the operating engaging member 141, 241 and the receiving surface 51d of the receiving member 151, 251, the engaging side protrusion 41n provided at the front end of the engaging surface 41k and the receiving side protrusion 51f provided at the front end of the receiving surface 51d are located at a position that crosses each other. In other words, when the engaging surface 41k and the receiving surface 51d face each other, the two engage with each other in a state where the base ends of each protrude toward the mating side. Therefore, as shown in Figures 14(d) and 15(d), even when the screen door 30 rotates clockwise and becomes tilted, the fastening surface 41k of the operating fastening member 141, 241 and the receiving surface 51d of the receiving member 151, 251 still maintain the fastening state, and the movement of the screen door 30 is restricted. When the fastening state between the fastening surface 41k and the receiving surface 51d is to be unlocked, the screen door 30 only needs to be moved close to the right edge frame member 13 and returned to the state shown in Figures 14(b) and 15(b), and then the operating fastening member 141, 241 is moved upward through the operating base.

In addition, in the above-mentioned embodiment 1, modification 1, and modification 2, the locking side protrusion 41n is provided on the locking surface 41k, and the receiving side protrusion 51f is provided on the receiving surface 51d, so that the front end side of each is protruded toward the matching side relative to the base end side, but the present invention is not limited thereto. For example, as in modification 3 shown in FIG. 16, the locking protrusion 341a of the lower locking member 341 and the receiving protrusion 351a of the receiving member 351 are provided with abutment surfaces 341b and 351b inclined relative to the front view direction B of the right edge frame member 13 and the right frame member 34 to form the locking surface 341c and the receiving surface 351c. When the inclination directions of the contact surfaces 341b and 351b face each other, they are configured to gradually protrude toward the mating side from the front end side. In variant 3, the contact surface 341b of the buckling surface 341c and the contact surface 351b of the receiving surface 351c are formed at the same inclination angle.

In the door and window equipped with the movement restriction device of this modification 3, if the operating fastening member 341 and the receiving member 351 move toward each other by the spring force of the tension coil spring 46 and the compression coil spring 54, the fastening surface 341c of the operating fastening member 341 and the receiving surface 351c of the receiving member 351 will be facing each other as shown in Figure 16 (b). Therefore, in this state, even when the screen door and window 30 is moved away from the right edge frame member 13, the fastening surface 341c of the operating fastening member 341 and the receiving surface 351c of the receiving member 351 still maintain the fastening state, and the movement of the screen door and window 30 is restricted.

Furthermore, as shown in FIG. 16( c ), even when the screen door and window 30 rotates clockwise relative to the edge frame 10 and is tilted, there is no risk that the front end side will pass over the base end side and be located on the inner peripheral side on the abutment surface 351b of the receiving member 351 that has been tilted in advance. Thus, even when the screen door and window 30 is tilted relative to the edge frame 10, the operating force applied to the screen door and window 30 will not generate a force in the direction of separating the operating fastening member 341 and the receiving member 351 from each other, so that the two maintain a fastened state, and the movement of the screen door and window 30 is restricted.

(Implementation Type 2)

In variation 3, abutment surfaces 341b and 351b are provided on both the buckling surface 341c and the receiving surface 351c, but the same effect can still be achieved by providing abutment surfaces inclined in a manner that the front end side gradually protrudes toward the mating side on at least one of the front end side of the buckling surface and the front end side of the receiving surface.

That is, in the embodiment 2 shown in FIG. 17 , only the receiving surface 451a of the receiving member 451 is provided with a contact surface 451b inclined relative to the front view direction B of the right frame member 34. The inclination direction of the contact surface 451b is the same as that of the variant 3. The locking surface 441a of the operating locking member 441 is provided with a locking surface 441b along the lead vertical direction. The other configurations are the same as those of the embodiment 1, and the same component symbols are marked.

In the door and window equipped with the movement restriction device constructed in the above manner, when the operating fastening member 441 and the receiving member 451 move toward each other due to the spring force of the tension coil spring 46 and the compression coil spring 54, as shown in FIG17(b), the fastening surface 441a of the operating fastening member 441 and the receiving surface 451a of the receiving member 451 are in a state of facing each other. Therefore, in this state, even when the screen door and window 30 is moved away from the right edge frame member 13, the fastening surface 441a of the operating fastening member 441 and the receiving surface 451a of the receiving member 451 still maintain the fastening state, and the movement of the screen door and window 30 is restricted.

Furthermore, even when the screen door and window 30 rotates clockwise relative to the edge frame 10 and is tilted, the contact surface 451b of the previously tilted receiving member 451 is extended in a direction close to vertical, as shown in FIG. 17(c), and the contact surface 451b with the buckling surface 441b along the vertical direction will increase. This allows the buckling surface 441a of the operating buckling member 441 to maintain a buckling state with the receiving surface 451a of the receiving member 451, and the movement of the screen door and window 30 is restricted.

Furthermore, in the above-mentioned embodiment 1, modification 1 to modification 3, and embodiment 2, the screen door and window 30 is exemplified as the door and window leaf, but it is not necessarily limited to the screen door and window 30. As long as it moves along the extension direction of the horizontal edge frame 11, it can be applied to other door and window leaves and the edge frame body 10. In addition, although the movement restriction device is set between it and the vertical edge frame 13 located on the right side when viewed from the indoor side, it is natural that the movement restriction device can also be set between it and the vertical edge frame 12 on the left side. Furthermore, although both the operating buckle member and the receiving member are configured to be movable in their respective front view directions B relative to the edge member and the frame member, it is sufficient that only one of the operating buckle member and the receiving member is movable. In this case, it is natural that the force-applying member only needs to be provided on the movable member. In addition, although a protective cap is provided as the receiving member, it is not necessarily necessary to provide a protective cap.

As described above, the movement restriction device of the present invention comprises: a buckling member, which is mounted on one of the edge member constituting the edge frame and the frame member constituting the door and window sash, and the door and window sash is configured to be movable relative to the edge frame; a receiving member, which is mounted on the other of the edge member and the frame member, wherein the movement of the door and window sash relative to the edge frame is restricted by making the buckling surface of the buckling member and the receiving surface of the receiving member buckle with each other, and the buckling member and the receiving member are configured to be movable relative to each other along the front view direction of the edge member and the frame member, and the front end side of the buckling surface and the front end side of the receiving surface are respectively provided with a portion protruding toward the matching side relative to the respective base end sides.

According to the present invention, the front end of the engaging surface and the front end of the receiving surface engage with each other in a state where they protrude toward the mating side relative to their respective base ends. Therefore, even when the frame is tilted relative to the edge frame, the engaging surface and the receiving surface remain engaged, thereby preventing the door and window sash from moving.

In addition, in the above-mentioned movement restriction device of the present invention, the buckling surface is provided with a buckling surface and a protrusion protruding toward the matching side at the front end side relative to the buckling surface, and the receiving surface is provided with a receiving surface and a protrusion protruding toward the matching side at the front end side relative to the receiving surface. When the protrusion of the buckling surface and the receiving surface of the receiving surface face each other, the buckling surface and the receiving surface buckle with each other.

According to the present invention, since the protrusion provided at the front end of the engaging surface and the protrusion provided at the front end of the receiving surface are engaged at a position that crosses each other, even when the frame is tilted relative to the edge frame, the engaging state between the engaging surface and the receiving surface is maintained, thereby preventing the door and window sash from moving.

In addition, in the above-mentioned movement restriction device, the present invention provides an introduction guide surface on the front end side of one of the protrusion of the buckle surface and the protrusion of the receiving surface, and the introduction guide surface abuts against the mating side when the buckle member and the receiving member move toward each other along the front view direction of the edge member and the frame member, and is inclined in a manner that the buckle member and the receiving member move relative to each other in the direction in which the buckle surface and the receiving surface separate from each other.

In addition, in the above-mentioned movement restriction device of the present invention, the frame member and the frame member each extend in the up-down direction, the buckling surface is arranged to protrude downward from the buckling member, the receiving surface is arranged to protrude upward from the receiving member, and the introduction guide surface is arranged on the part above the protruding part of the receiving surface and is inclined in a manner of gradually protruding downward.

According to these inventions, through the tilting effect of the introduction guide surface, it is easy to arrange the protrusion of the snap-fit component and the protrusion of the receiving component across the protrusion of the mating side to the side of the base end.

In addition, in the above-mentioned movement restriction device, the present invention provides an unlocking guide surface on the base end side of at least one of the protruding portion of the fastening surface and the protruding portion of the receiving surface. When the fastening surface and the receiving surface are in a state of being fastened to each other, the fastening member and the receiving member move in a direction of separation from each other along the front view direction of the edge member and the frame member, and the unlocking guide surface abuts against the mating side, and is tilted in a manner such that the fastening member and the receiving member move relative to each other in a direction in which the interval between them becomes wider.

In addition, in the above-mentioned movement restriction device of the present invention, the frame member and the frame member each extend in the up-down direction, the buckling surface is arranged to protrude downward from the buckling member, the receiving surface is arranged to protrude upward from the receiving member, and the unlocking guide surface is respectively arranged at the part above the protruding part of the buckling surface and the part below the protruding part of the receiving surface, the unlocking guide surface of the buckling surface is inclined in a manner of gradually protruding downward, and the unlocking guide surface of the receiving surface is inclined in a manner of gradually protruding upward.

According to the invention, the inclination of the unlocking guide surface makes it easier to unlock the fastening state between the fastening member and the receiving member.

In addition, in the above-mentioned movement restriction device of the present invention, abutment surfaces are provided on the buckling surface and the receiving surface, and the abutment surfaces are respectively protruded gradually from the front end side to the matching side, and are inclined relative to the front view direction of the edge member and the frame member. When the abutment surfaces are in a state of abutting each other, the buckling surface and the receiving surface are buckled with each other.

According to this invention, since the abutting surface is inclined, even when the door and window sash is inclined relative to the edge frame, it is still difficult to disengage the fastening state between the fastening surface and the receiving surface, which can prevent the door and window sash from moving.

In addition, in the above-mentioned movement restriction device, a force-applying member is provided on at least one of the buckling member and the receiving member, which applies force to the buckling member and the receiving member in a direction in which the buckling member and the receiving member are brought closer to each other along the front view direction of the edge member and the frame member.

According to this invention, no operation is required when fastening the fastening member and the receiving member to each other, which is advantageous from the perspective of convenience.

In addition, the movement restriction device of the present invention comprises: a locking member, which is installed on one of the edge member constituting the edge frame and the frame member constituting the door and window sash, and the door and window sash is configured to be movable relative to the edge frame; and a receiving member, which is installed on the other of the edge member and the frame member, wherein the locking surface of the locking member and the receiving surface of the receiving member are locked with each other to restrict the movement of the door and window sash relative to the edge frame, The buckling member and the receiving member are configured to be relatively movable along the front view direction of the edge member and the frame member. At least one of the front end side of the buckling face and the front end side of the receiving face is provided with a contact surface. The contact surface is inclined relative to the front view direction of the edge member and the frame member in a manner that the front end side gradually protrudes toward the matching side. When the contact surface is in contact with the matching side, the buckling face and the receiving face are buckled with each other.

According to the invention, at least one of the front end of the engaging surface and the front end of the receiving surface is tilted in a manner protruding toward the mating side relative to the base end. Therefore, even when the frame is tilted relative to the edge frame, the engaging state between the engaging surface and the receiving surface can still be maintained, thereby preventing the screen door and window from moving inadvertently.

In addition, the door and window of the present invention is provided with the above-mentioned movement restriction device between the edge frame member constituting the edge frame body and the frame member constituting the screen door and window, and the screen door and window is configured to be movable relative to the edge frame body.

According to this invention, since the front end of the fastening surface and the front end of the receiving surface are fastened to each other in a state where they protrude toward the matching side relative to their respective base ends, even if the frame of the screen door and window is tilted relative to the edge frame, the fastening state between the fastening surface and the receiving surface can still be maintained, which can prevent the screen door and window from moving inadvertently.
