Description

Technical Field

[0001] The present invention relates to a door and window provided with a door and window sash, wherein the door and window sash is supported on a frame body in a slidable manner. Background Art

[0002] Regarding doors and windows such as sliding windows, in which door and window sashes are supported so as to be able to slide relative to a frame, there is provided a door and window that is provided with a sliding restriction device for restricting sliding in addition to a locking device such as a crescent lock. In the door and window with the sliding restriction device, for example, a stopper is provided on the lower frame of the outer door and window sash so as to be able to advance and retreat. By maintaining the stopper in a forward position, the sliding of the inner and outer door and window sashes can be restricted (for example, see Patent Document 1).

[0003] Patent Document 1: Japanese Patent Application Laid-Open No. 2004-360312 Summary of the Invention

[0004] However, in the above-mentioned doors and windows, in order to maintain the stopper in the state after the forward movement, it is necessary to utilize a key to perform a locking operation. Therefore, not only does the operation of restricting the sliding of the door and window sash become complicated, but also it is difficult to restrict the sliding of the door and window sash when the locking operation is forgotten.

[0005] The present invention is proposed in view of the above-mentioned actual situation, and its purpose is to provide a door and window that can limit the sliding of the door and window sash without performing complicated operations.

[0006] In order to achieve the above-mentioned purpose, the doors and windows of the present invention include door and window sashes slidably supported on a frame body, and a stopper arranged on the main viewing surface of the door and window sash in a manner that allows it to move forward and backward. When the door and window sash is slid in the opening direction after the stopper moves forward, the stopper abuts against the end face of the abutted component through the front end portion, thereby restricting the sliding of the door and window sash. The doors and windows include: a force-applying component for applying force to the stopper in the forward direction, and a rolling body is provided at the front end portion of the stopper. When the stopper moves forward in a state where it is arranged at a position relative to the surface of the abutted component, the rolling body can abut against the surface.

[0007] According to the present invention, the stopper is pushed in the forward direction by the force-applying member, thereby limiting the sliding of the door or window sash without complicated operations. Furthermore, the stopper is provided with a rolling element, so that even if the door or window sash slides while the stopper is in contact with the surface of the contacted member, the contacted member will not be damaged.

The so-called depth direction refers to the direction along the depth of the doors and windows as shown by the arrow A in the figure. For the surface along the depth direction, it can be called the depth surface. The so-called main viewing surface direction, if it is a component extending in the horizontal direction such as the lower frame, refers to the direction perpendicular to the depth direction and along the up-down direction. If it is a component extending in the up-down direction such as the vertical frame, the direction perpendicular to the depth direction and along the horizontal direction is called the main viewing surface direction. For the surface along the main viewing surface direction, it can be called the main viewing surface.

[0027] Implementation Method 1

[0028] Figure 1 、 Figure 2It is a figure showing the doors and windows of embodiment 1 of the present invention. The doors and windows illustrated here are doors and windows called sliding windows, which have a frame body 10, and an inner door and window sash 20A and an outer door and window sash 20B supported on the frame body 10 in a manner that can slide left and right relative to the frame body 10. The frame body 10 is composed of four sides surrounded by an upper frame 11, a lower frame 12 and left and right longitudinal frames 13. The longitudinal frames 13 constituting the frame body 10 are composed of a metal frame portion 13M on the outdoor side formed of a metal such as an aluminum alloy, and a resin frame portion 13P formed of a resin. The metal frame portion 13M and the resin frame portion 13P are both extruded profiles, and are respectively constructed so that each portion along the entire length direction has a substantially identical cross-sectional shape. In addition, although not clearly shown in the figure, the upper frame 11 and the lower frame 12 are also constructed to have a metal frame portion and a resin frame portion, respectively, like the longitudinal frame 13.

[0029] The inner door and window sash 20A and the outer door and window sash (the abutted component) 20B are both constructed by supporting a panel 25, such as multi-layer glass, within a frame. The frame is constructed by connecting an upper frame 23 between the upper ends of the left and right longitudinal frames 21 and 22, and connecting a lower frame 24 between the lower ends of the longitudinal frames 21 and 22. The longitudinal frames 21 and 22 that constitute the door and window sashes 20A and 20B are respectively constructed to have metal frame portions 21M and 22M on the outdoor side formed from a metal such as an aluminum alloy, and resin frame portions 21P and 22P formed from a resin. The metal frame portions 21M and 22M and the resin frame portions 21P and 22P are all extruded profiles, and are each constructed so that each portion along the entire length has a substantially identical cross-sectional shape. In addition, although not explicitly shown in the figure, the upper frame 23 and the lower frame 24 are also constructed to have a metal frame portion and a resin frame portion, respectively, like the longitudinal frames 21 and 22.

[0030] Depend on Figure 2 It can also be seen that the left and right vertical frames 21 and 22 are configured to be larger in the depth direction than the lower frame 24, and are connected to the lower frame 24 so as to overlap with the main view surface of the lower frame 24. In other words, the main view surfaces facing indoors and outdoors of the vertical frames 21 and 22 are both located at positions that protrude from the main view surface of the lower frame 24, and a step d is formed between each vertical frame 21 and 22 and the lower frame 24.

[0031] The inner door and window sash 20A and the outer door and window sash 20B are configured to have the following size: when the inner door and window sash 20A and the outer door and window sash 20B are both configured in the closed position, the opening of the frame body 10 can be closed. In the example shown in the figure, when viewed from the indoor side, the left side is the closed position of the outer door and window sash 20B, and the right side is the closed position of the inner door and window sash 20A. A crescent lock 30 is provided between the longitudinal frame 22 of the matching position of the outer door and window sash 20B and the longitudinal frame 22 of the matching position of the inner door and window sash 20A. When the locking operation is performed in the state that the inner door and window sash 20A and the outer door and window sash 20B are both configured in the closed position, the crescent lock 30 prevents the inner door and window sash 20A and the outer door and window sash 20B from sliding in the opening direction.

[0032] In addition, a sliding restriction device 40 is provided on the lower frame (first frame) 24 of the inner door and window sash 20A. The sliding restriction device 40 is a device for restricting the sliding of the inner door and window sash 20A and the outer door and window sash 20B even when the crescent lock 30 is in the unlocked state. That is, the sliding restriction device 40 is a device for restricting the sliding of the inner door and window sash 20A and the outer door and window sash 20B in the opening direction when it is in the locked state, and for releasing the sliding restriction of the inner door and window sash 20A and the outer door and window sash 20B when it is in the unlocked state, so that the inner door and window sash 20A and the outer door and window sash 20B can be opened to the fully open position. The structure of the sliding restriction device 40 is described below. Figures 3 to 6 As shown, the slide restricting device 40 is configured to include a housing 41 , a stopper 42 , and an unlocking unit 43 .

[0033] The housing 41 includes a housing body 41a, which is a hollow rectangular parallelepiped with an open surface on one side. A flange 41b is provided integrally with the housing body 41a in the portion surrounding the opening of the housing body 41a. In this first embodiment, the housing 41 is configured such that its length is elongated along the direction in which the lower frame 24 extends, and the width dimension of the flange 41b along the vertical direction is smaller than the dimension of the lower frame 24 along the main viewing surface. A pin insertion hole 41c is provided in the bottom wall of the housing 41, located on the front end side of the inner door and window sash 20A (the right side when viewed from the indoor side). The flange 41b is brought into contact with the main surface of the lower frame 24 facing the outside, and a back plate 44 is provided in the hollow portion of the lower frame 24 at portions corresponding to the ends of the flange 41b. Screw members N1 are threaded through the flange 41b and the lower frame 24 and screwed into the back plate 44. Thus, the housing 41 is mounted to the lower frame 24 of the inner door and window sash 20A through the stopper opening 24a of the lower frame 24, with the opening of the housing body 41a facing the outside. The housing 41 is mounted at a position where a gap is formed between the longitudinal frame 22 at the joint with the outer door and window sash 20B when the inner door and window sash 20A is in the closed position.

[0034] The stopper 42 is sized to fit within the housing 41 and is rotatably supported by the housing 41 via a support shaft 45 extending vertically. The support shaft insertion hole 42a for the support shaft 45 is located in the portion of the stopper 42 that is closer to the base end than the longitudinal center. In the illustrated example, the support shaft 45 is positioned at the front end of the inner door / window sash 20A, i.e., on the side of the vertical frame 21 (on the right side when viewed from the interior), and the stopper 42 is designed to be retracted into the housing 41 by rotating counterclockwise about the support shaft 45. On the other hand, when the stopper 42 is rotated clockwise about the support shaft 45, it assumes an inclined position, gradually protruding toward the vertical frame 22 (on the left side when viewed from the interior) at the point where the inner door / window sash 20A meets the vertical frame 22, that is, toward the end face of the outer door / window sash 20B in the closed position, i.e., the vertical frame 22. The protruding size of the stopper 42 toward the outside of the room is limited by the base end thereof abutting against the inner bottom surface of the housing 41. In this embodiment 1, the protruding size of the stopper 42 is set so that the front end of the stopper 42 is located at a position opposite to the longitudinal frame 22 of the outer door and window sash 20B arranged in the closed position. A push spring (force-applying component) 46 is provided between the stopper 42 and the housing 41. The push spring 46 is sandwiched between the portion of the stopper 42 that is closer to the front end side than the support shaft 45 and the housing 41, and always applies force to the front end of the stopper 42 in the direction of advancement relative to the housing 41. Regardless of the rotational posture of the stopper 42, the base end of the stopper 42 is always in a state of being arranged at a position opposite to the pin insertion hole 41c of the housing 41.

[0035] The front end of the stopper 42 is provided with an abutment body 47 and a roller (rolling body) 48. The abutment body 47 and the roller 48 are supported on the front end of the stopper 42 via roller shafts 49 extending in the vertical direction. The abutment body 47 forms a flat abutment surface 47a at the front end of the stopper 42 and is arranged in a state in which it cannot move relative to the stopper 42. In this embodiment 1, as shown in FIG. Figure 6 As shown in (a), the abutment body 47 is provided on the stopper 42 in the following manner: when the front end of the stopper 42 protrudes toward the outside to the maximum extent, the abutment surface 47a is opposite to the longitudinal frame 22 side of the inner door and window sash 20A (the left side when viewed from the indoor side), that is, the longitudinal frame 22 of the outer door and window sash 20B arranged in the closed position, and the abutment surface 47a is substantially vertical along the depth direction. Figure 6As shown in (b), the abutment 47 is provided on the stopper 42 in such a manner that when the stopper 42 is accommodated in the housing 41, the abutment 47 retracts to the indoor side relative to the main surface of the lower frame 24 facing the outdoors. The roller 48 is provided on the stopper 42 in such a manner that, regardless of the position of the stopper 42, a portion of its circumference always protrudes further toward the outdoors than the stopper 42 and the abutment 47. The roller 48 is provided on the stopper 42 in such a manner that, when the stopper 42 is accommodated in the housing 41, the roller 48 and the main surface of the housing 41 facing the outdoors are substantially flush with each other.

[0036] like Figure 3 、 Figure 5 、 Figure 6 As shown, the unlocking unit 43 is constructed with a unit body 51, a push pin 52, and an unlocking component 53. The unit body 51 has an insertion hole 51a at one end and a pin receiving hole 51b at the other end. The insertion hole 51a is a space with a transverse slit-like cross-section and opens to one end face of the unit body 51. The pin receiving hole 51b has a circular cross-section and opens to the other end face of the unit body 51. The insertion hole 51a and the pin receiving hole 51b are interconnected within the unit body 51, with their axes aligned. The opening of the pin receiving hole 51b is configured to have a diameter smaller than the inner diameter of the pin receiving hole 51b. The unit body 51 is mounted to the lower frame 24 of the inner door and window sash 20A by aligning the opening of the pin receiving hole 51b with the pin insertion hole 41c of the housing 41 and threading the screw member N2 through the lower frame 24 while the opening of the insertion hole 51a is open to the interior of the room via the component insertion hole 24b of the lower frame 24. like Figure 5 As shown, in the first embodiment, the unit main body 51 is composed of two parts: the part insertion body 51c and the pin storage body 51d.

[0037] The push pin 52 is a component having a flange 52b at the base end of a cylindrical pin body 52a. The diameter of the pin body 52a is smaller than the opening of the pin receiving hole 51b. The diameter of the flange 52b is larger than the opening of the pin receiving hole 51b and smaller than the inside of the pin receiving hole 51b. The push pin 52 is arranged in the pin receiving hole 51b with the front end of the pin body 52a facing the outside. The axial dimension of the push pin 52 is set so that when the flange 52b is abutted against the end face of the part insert 51c, the front end is in the following state: it protrudes from the opening of the pin receiving hole 51b to the outside of the unit body 51 and is exposed to the inside of the housing 41 through the pin insertion hole 41c. A retraction spring 54 is provided around the pin body 52a. The retraction spring 54 is interposed between the flange 52b and the pin receiving body 51d, thereby constantly biasing the push pin 52 to remain received in the pin receiving hole 51b. When the push pin 52 is advanced from the unit body 51 in a protruding direction against the elastic force of the retraction spring 54, it pushes against the base end of the stopper 42, causing the stopper 42 to be received within the housing 41 against the elastic force of the push spring 46.

[0038] like Figure 6 As shown, the unlocking part 53 is in the shape of a flat plate with a front end that is narrower than the base end. More specifically, the unlocking part 53 is configured to have a width such that its front end can be inserted into the insertion hole 51a from one end face of the unit body 51, and the base end cannot be inserted into the insertion hole 51a. The size of the base end along the length direction is set so that even if the base end is inserted into the insertion hole 51a and abuts against the end face of the part insert 51c, it will protrude from the main viewing surface of the lower frame 24 facing the room. The front end of the unlocking part 53 is configured to have a width that can be inserted into the pin receiving hole 51b. The size of the front end along the length direction is configured so that when the front end passes through the insertion hole 51a and is inserted into the pin receiving hole 51b, it can push the base end of the stopper 42 so that the front end of the stopper 42 is received in the housing 41.

[0039] In the door and window constructed in the above manner, even if the crescent lock 30 is in the unlocked state, as long as the unlocking part 53 is not inserted into the unlocking unit 43, Figure 2 As shown, the front end of the stopper 42 is maintained in a state of maximum projection toward the outside of the room by the elastic force of the push spring 46. Therefore, even if the inner door and window sash 20A and the outer door and window sash 20B are slid in the direction of opening from this state, the stopper 42 will be in a state of maximum projection toward the outside of the room. Figure 7 As shown, before reaching the fully open position, the abutment body 47 provided at the front end of the stop member 42 abuts against the longitudinal frame 22 at the mating point of the outer door and window sash 20B through the abutment surface 47a, thereby preventing the inner door and window sash 20A and the outer door and window sash 20B from continuing to slide in the opening direction.

[0040] On the other hand, when the unlocking part 53 is inserted into the unlocking unit 43, Figure 8 As shown, the stopper 42 can be accommodated in the housing 41. Therefore, when the inner door and window sash 20A and the outer door and window sash 20B are slid while maintaining this state, the front end of the stopper 42 does not abut against the longitudinal frame 22 at the joint of the outer door and window sash 20B, and the inner door and window sash 20A and the outer door and window sash 20B can slide to the fully open position.

[0041] Here, if Figure 9 As shown, if at least one of the inner door and window sash 20A and the outer door and window sash 20B slides from the closed position to the open direction, and the operating force of the unlocking part 53 is removed when the stopper 42 is in a position opposite to the outer door and window sash 20B, the push pin 52 retreats due to the elastic force of the retraction spring 54, and the front end of the stopper 42 is maintained in the state after moving in the forward direction due to the elastic force of the push spring 46. Therefore, if the inner door and window sash 20A and the outer door and window sash 20B are slid to the closed position from this state, they will return to the closed position. Figure 2 Thus, the sliding of the inner door and window sash 20A and the outer door and window sash 20B can be restricted without subsequent operations, thereby preventing the inner door and window sash 20A and the outer door and window sash 20B from accidentally moving to the fully open position without complicated operations.

[0042] And, as Figure 9 As shown in FIG. 1 , when the inner door and window sash 20A or the outer door and window sash 20B is slid, the peripheral surface of the roller 48 provided at the front end of the stopper 42 abuts against the lower frame (second frame) 24 of the outer door and window sash 20B. Therefore, the roller 48 rolls appropriately without causing scratches or other damage to the main surface of the lower frame 24. Moreover, although the main surfaces of the vertical frames (third frames) 21 and 22 of the outer door and window sash 20B are more prominent than the main surface of the lower frame 24, as shown in FIG. Figure 10 、 Figure 11 As shown, even when passing through the step d from the lower frame 24 to the longitudinal frames 21 and 22, the main viewing surfaces of the lower frame 24 and the longitudinal frames 21 and 22 will not directly contact the stopper 42 or the abutment 47. Instead, the circumferential surface of the roller 48 contacts the main viewing surfaces of the lower frame 24 and the longitudinal frames 21 and 22. Therefore, the main viewing surfaces of the longitudinal frames 21 and 22 will not be damaged.

[0043] Implementation Method 2

[0044] Figure 12 、 Figure 13: This is a diagram showing doors and windows according to Embodiment 2 of the present invention. As in Embodiment 1, the doors and windows illustrated here are what are called sliding windows, which include a frame body 10, and an inner door and window sash 20A and an outer door and window sash (abutted member) 20B supported on the frame body 10 in a manner that allows them to slide left and right relative to the frame body 10. The structure of the longitudinal frame 21 at the front end of the side door and window sash of the outer door and window sash 20B and the detailed structure of the slide limiting device 40 are different from those in Embodiment 1. Below, the main points different from Embodiment 1 are described, and the same symbols are given to the same structures as in Embodiment 1, and detailed descriptions are omitted.

[0045] In the outer door and window sash 20B of embodiment 2, a groove 120 is provided on the main viewing surface of the resin frame portion 21P of the longitudinal frame 21 facing the room. The groove 120 also functions as a handle when the outer door and window sash 20B is opened and closed, and is provided along the entire length of the longitudinal frame 21 in the up and down directions. Specifically, the groove 120 is formed so that its left and right inner walls 120a and 121a extend in the depth direction in a manner parallel to each other. The two opening edges 120b and 121b of the groove 120 located on the left and right are located on the same plane along the main viewing surface direction. As shown in FIG. Figure 14 As shown, the relationship between the width dimension w of the groove 120 along the left-right direction and the dimensions of the abutting body (abutting portion) 47 and the roller (rolling element) 48 provided on the stopper 42 is set as follows. That is, it is set so that the abutting body 47 and the roller 48 of the stopper 42 can abut the two opening edges 120b and 121b of the groove 120 at the same time, and at this time, the abutting surface 47a of the abutting body 47 is located on the indoor side relative to the main viewing surface passing through the opening edge 120b on the front side of the door and window sash. In addition, when the abutting body 47 and the roller 48 abut the two opening edges 120b and 121b at the same time, the collision surface 47b of the abutting body 47 that abuts the opening edge 120b of the groove 120 gradually tilts toward the indoor side toward the front side of the door and window sash. In the example shown in the figure, the width dimension w of the groove 120 along the left-right direction is substantially the same as the outer diameter of the roller 48.

[0046] On the other hand, Figure 15 、 Figure 16 As shown, in the sliding restriction device 40 used in the door and window of embodiment 2, the push pin 52 of the unlocking unit 43 provided on the lower frame 24 of the inner door and window sash 20B is installed with an airtight member 55. The airtight member 55 is formed from an elastic material such as resin into a circular ring shape in cross section and is installed in a mounting groove 52c provided on the circumferential surface of the pin body 52a. The position where the airtight member 55 is provided is a position opposite to the inner circumferential surface of the pin receiving hole 51b provided on the unit body 51 when the push pin 52 is in the retracted state under the action of the retraction spring 54. The symbol 24M in the figure represents the metal frame portion of the lower frame 24, and the symbol 24P represents the resin frame portion of the lower frame 24.

[0047] In the door and window of the second embodiment constructed as described above, as long as the unlocking member 53 is not inserted into the unlocking unit 43, Figure 12 As shown, the front end of the stopper 42 is maintained in a state of protruding to the outside to the greatest extent by the elastic force of the push spring (biasing member) 46. Therefore, when the inner door and window sash 20A and the outer door and window sash 20B are slid in the opening direction from this state, even if the crescent lock 30 is in the unlocked state, before reaching the fully open position, the abutment body 47 provided at the front end of the stopper 42 abuts against the longitudinal frame 22 at the joint of the outer door and window sash 20B through the abutment surface 47a, thereby preventing the inner door and window sash 20A and the outer door and window sash 20B from sliding further in the opening direction.

[0048] On the other hand, after the unlocking part 53 is inserted into the unlocking unit 43, the stopper 42 is accommodated in the housing 41, so the front end of the stopper 42 does not abut against the longitudinal frame 22 at the joint of the outer door and window sash 20B, and the inner door and window sash 20A and the outer door and window sash 20B can slide to the fully open position. When the operating force of the unlocking part 53 is removed at the position where the stopper 42 and the outer door and window sash 20B are opposite, the front end of the stopper 42 is maintained in the state after moving in the forward direction under the action of the elastic force of the push spring 46, so that the inner door and window sash 20A and the outer door and window sash 20B slide to the closed position, and can be restored again. Figure 12 Thus, the sliding of the inner door and window sash 20A and the outer door and window sash 20B can be restricted without subsequent operation.

[0049] Here, if Figure 13 As shown, when the longitudinal frame 21 at the front end of the side sash of the outer door and window sash 20B slides over the longitudinal frame 22 at the mating portion of the inner door and window sash 20A, the roller 48 of the stopper 42 may reach the groove 120. However, in this door and window, the width dimension w of the groove 120 in the left-right direction and the dimensions of the abutting body 47 and roller 48 provided on the stopper 42 are configured to meet the above conditions. Therefore, the abutting surface 47a of the abutting body 47 does not enter the interior of the groove 120. Moreover, when the abutting body 47 and roller 48 simultaneously abut against both opening edges 120b and 121b, the collision surface 47b of the abutting body 47 that abuts against the opening edge 120b of the groove 120 gradually tilts toward the front end of the door and window sash and toward the interior of the room. As a result, although a portion of the roller 48 enters the groove 120 , the contact surface 47 a is not caught by the opening edge 120 b of the groove 120 , and the inner door and window sash 20A and the outer door and window sash 20B can continue to move relative to each other.

[0050] In addition, in the doors and windows of embodiment 2, an airtight part 55 is provided around the push pin 52, so that when the inner door and window sash 20A and the outer door and window sash 20B are respectively arranged in the closed position and the unlocking part 53 is not inserted, it is possible to prevent indoor and outdoor air from circulating through the pin storage hole 51b.

[0051] Furthermore, while the above embodiment illustrates a sliding window with an inner door and window sash 20A and an outer door and window sash 20B, it can also be applied to a single-sash sliding window in which one of the door and window sashes is fixed, or a single-sash sliding window with a single door and window sash. In the former, the fixed door and window sash serves as the abutted component, while in the latter, the abutted component is a wall or panel that overlaps the door and window sash in the depth direction when it is in the open position. Furthermore, the sliding direction of the door and window sash is not necessarily limited to the left-right direction; it can also be the up-down direction. Furthermore, while the stopper 42 is configured to protrude from the lower frame 24 of the inner door and window sash 20A toward the outside of the room in the sliding window, the stopper 42 can also be configured to protrude from the lower frame 24 of the outer door and window sash 20B toward the inside of the room. In this case, the unlocking unit 43 or the unlocking component 53 is not necessarily required. Furthermore, the lower frame and vertical frame of the door and window sash do not necessarily require a metal frame portion or a resin frame portion; they can also be formed solely of metal or resin.

[0052] In addition, in the above embodiment, the roller 48 is shown as an example of a rolling body, but other rolling bodies such as balls can also be used as long as they roll when the door or window sash slides. In addition, although the abutting body 47 as an independent body is provided at the front end of the stopper 42 to form the abutting surface 47a with the abutted component, the stopper 42 can also be made to directly abut the abutted component as the abutting portion.

[0053] Furthermore, in the above embodiment, the stopper 42 is shown as being rotatably supported via the support shaft 45 and protruding in an inclined position. However, the stopper 42 does not necessarily need to rotate to move forward or backward, nor does it necessarily need to adopt an inclined position after moving forward. Furthermore, as an example of a biasing member, a compression spring 46 is shown as a coil spring, but other biasing members such as a torsion spring or a leaf spring may also be used.

[0054] Furthermore, while the aforementioned second embodiment illustrates a door or window in which the two opening edges 120b and 121b are located on the same plane along the main viewing plane, this is not limiting. For example, the groove may be formed such that the opening edge on the front end of the door or window sash protrudes further toward the interior of the room than the opening edge on the mating side. In this case, the circumferential surface of the rolling element and the abutment element can also abut both opening edges of the groove simultaneously. In this case, as long as the abutment surface is located on the exterior side of the groove relative to the main viewing plane passing through the opening edge on the front end of the door or window sash, the same functional effects as those of the second embodiment can be achieved.

[0055] As described above, the doors and windows of the present invention include door and window sashes slidably supported on a frame body, and stoppers arranged on the main viewing surface of the door and window sashes in a manner that allows them to move forward and backward. When the door and window sashes are slid in the opening direction after the stoppers have moved forward, the stoppers abut against the end surface of the abutted component through the front end portion, thereby restricting the sliding of the door and window sashes. The doors and windows include: a force-applying component for applying force to the stopper in the forward direction, a rolling body being provided at the front end portion of the stopper, and when the stopper moves forward in a state arranged at a position relative to the surface of the abutted component, the rolling body can abut against the surface.

[0056] According to the present invention, the stopper is pushed in the forward direction by the force-applying member, thereby restricting the sliding of the door or window sash without complicated operations. Furthermore, the stopper is provided with a rolling element, so that even if the door or window sash slides while the stopper is in contact with the surface of the contacted member, the contacted member will not be damaged.

[0057] Furthermore, in the present invention, in the above-mentioned door and window, the base end portion of the stopper is rotatably supported via a support shaft, and after the stopper moves forward relative to the door and window sash, it is inclined so as to gradually protrude toward the end surface of the abutted component.

[0058] According to the present invention, the stopper is inclined in the state after being advanced, so when the door or window sash is slid toward the closed position, the stopper does not become an obstacle.

[0059] Furthermore, the present invention provides the above-mentioned doors and windows, wherein the door and window sashes are slidably provided on the outdoor side and the indoor side of the frame body, and the stopper is provided on one door and window sash with the other door and window sash as the abutted component.

[0060] According to the present invention, the sliding movement of the door or window sash of the sliding window can be restricted.

[0061] In addition, the present invention is that, in the above-mentioned doors and windows, the stop member is arranged in a first frame extending along the sliding direction of the door and window sash on one side corresponding to a second frame extending along the sliding direction of the door and window sash on the other side, and the stop member limits the sliding of the door and window sash on one side by abutting against the end face of the door and window sash on the other side.

[0062] According to the present invention, when the door and window sash is slid, the stopper contacts the second frame of the other door and window sash, thereby preventing damage to a panel such as glass provided on the other door and window sash.

[0063] In addition, the present invention is that in the above-mentioned doors and windows, the other side door and window sash has a third frame, and the third frame is arranged in a state of extending in a direction perpendicular to the second frame and overlapping with the main viewing surface of the second frame, and the rolling body protrudes from the stop member in a manner capable of abutting against the step between the second frame and the third frame.

[0064] According to the present invention, even when passing through the step between the second frame and the third frame, the rolling body is used for abutment, so the sliding of the door and window sash is not hindered.

[0065] Furthermore, in the above-mentioned door and window, the present invention is such that the stopper is maintained in a state of being retracted against the force applied by the urging member when the unlocking component is inserted.

[0066] According to the present invention, the sliding restriction on the door and window sash can be released by inserting the unlocking part. Therefore, the stopper can be configured to move from the part of the door and window sash facing the outside toward the outside, which is advantageous in terms of appearance quality.

[0067] In addition, the present invention is that, in the above-mentioned doors and windows, the stopper abuts against the end face of the other side door and window sash located on the mating side through the abutting surface of the abutting portion provided at the front end portion, thereby limiting the sliding of the door and window sash, and in the front end portion of the door and window sash of the other side, a groove extending in the up and down directions is provided on the surface on the side opposite to the one side door and window sash, and in the rolling body and the abutting portion, the circumferential surface of the rolling body and the abutting portion can abut against the two opening edges of the groove at the same time, and when the circumferential surface of the rolling body and the abutting portion abut against the two opening edges of the groove, the abutting surface is located on the outer side of the groove relative to the main viewing surface passing through the opening edge of the front end side of the door and window sash.

[0068] According to the present invention, for example, when doors and windows are provided with grooves serving as handles, when the two door and window sashes are respectively arranged in the open position, even if the stopper and the rolling body pass through the groove, the abutment surface will not enter the interior of the groove, and they can be moved to the fully open position without being stuck.

[0069] In addition, the present invention is that in the above-mentioned doors and windows, the abutting portion abuts against the opening edge of the groove simultaneously with the circumferential surface of the rolling body through the collision surface, and when the collision surface abuts against the opening edge of the groove simultaneously with the circumferential surface of the rolling body, it is inclined toward the opening edge of the front end side of the door and window sash and gradually away from the other side door and window sash.

[0070] According to the present invention, since the collision surface is inclined, the operation of opening the door or window sash to the fully open position can be easily performed by the inclination effect.

[0071] In addition, the present invention is that in the above-mentioned doors and windows, the door and window sash is equipped with a push pin, and the push pin presses the stopper to retract it when the unlocking part is inserted. The push pin is arranged in a pin receiving hole provided in the unit body in a manner that allows it to move forward and backward, and an air-tight part is provided between the pin receiving hole and the circumferential surface of the push pin.

[0072] According to the present invention, it is possible to prevent indoor and outdoor air from flowing through the gap between the pressing pin and the pin receiving hole of the unit body.
