Description

Movement limiting device and door and window

Technical Field

The present invention relates to a movement limiting device for limiting movement of a door sash such as a window and a door, and to a door.

Background

Some of doors and windows having door and window wings are provided with movement limiting means for limiting movement of the door and window wings along a rail of a jamb. As such a movement limiting device, a movement limiting device that is used in many cases includes: a clamping component which is arranged on a longitudinal frame forming the frame body and takes a downward L shape; and a receiving member attached to a vertical frame constituting the door and window sash and having an upward L-shape (see patent document 1, for example). In this movement limiting device, for example, in a state where the vertical frame of the door and window sash is brought into contact with the vertical frame of the frame body, the movement of the vertical frame in the separating direction with respect to the vertical frame can be limited by bringing the engagement surface of the engagement member and the receiving surface of the receiving member into contact with each other.

Disclosure of Invention

On the other hand, in the above-described movement restriction device, when the height position at which the person applies the operation force to the door and window sash is substantially the same as the height position at which the engaging member and the receiving member are mounted, the abutting state between the engaging surface and the receiving surface is maintained at the time of the pulling operation to the door and window sash, and therefore the movement of the door and window sash can be restricted. When the height position of the engaging member and the receiving member is offset from the height position of the door and window sash by a person, the vertical frame of the door and window sash may be inclined with respect to the vertical frame of the frame body when the door and window sash is pulled. Therefore, in the movement limiting device, there is a concern that the receiving surface of the receiving member attached to the vertical frame is inclined with respect to the engaging surface of the engaging member attached to the vertical frame. The abutting state between the engaging member and the receiving member is maintained by the urging force of springs arranged along the longitudinal frame and the extending direction of the longitudinal frame. However, in a state where the receiving surface of the receiving member is inclined, an operation force at the time of a pulling operation on the door and window sash may generate a force against the urging force of the spring, and the engaging member and the receiving member may be moved in a direction to separate from each other, resulting in release of the abutting state of each other.

In view of the above, the present invention aims to provide a movement limiting device and a door and window that can more reliably limit the movement of a door and window sash relative to a frame body.

In order to achieve the above object, a movement limiting device of the present invention includes: an engaging member attached to one of a frame member constituting the frame body and a frame member constituting a door sash, the door sash being configured to be movable with respect to the frame body; and a receiving member attached to the other of the frame member and the frame member, wherein the engaging surface portion of the engaging member and the receiving surface portion of the receiving member are engaged with each other to restrict movement of the door/window sash relative to the frame body, the engaging member and the receiving member are disposed so as to be movable relative to each other along an extending direction of the frame member and the frame member, and a portion protruding toward the other side than the base end side of each of the engaging surface portion and the receiving surface portion is provided on the front end side of the engaging surface portion.

Further, the movement limiting device of the present invention includes: an engaging member attached to one of a frame member constituting the frame body and a frame member constituting a door sash, the door sash being configured to be movable with respect to the frame body; and a receiving member attached to the other of the frame member and the frame member, wherein the engaging surface portion of the engaging member and the receiving surface portion of the receiving member are engaged with each other to restrict movement of the door/window sash relative to the frame body, the engaging member and the receiving member are arranged so as to be movable relative to each other along an extending direction of the frame member and the frame member, and an abutment surface is provided on at least one of a distal end portion side of the engaging surface portion and a distal end portion side of the receiving surface portion, and the abutment surface is inclined relative to an extending direction of the frame member and the frame member so as to gradually protrude toward the distal end side, and the engaging surface portion and the receiving surface portion are engaged with each other in a state in which the abutment surface and the receiving surface portion are abutted against each other.

According to the present invention, since the front end portion of the engaging surface portion and the front end portion of the receiving surface portion are engaged with each other in a state protruding toward the opposite side from the respective base end portions when facing each other, even when the frame member is inclined with respect to the frame member, the engaging state between the engaging surface portion and the receiving surface portion can be maintained, and movement of the door and window can be prevented.

Further, according to the present invention, at least one of the front end portion of the engaging surface portion and the front end portion of the receiving surface portion is inclined so as to protrude toward the other side than the base end portion when the front end portion and the receiving surface portion face each other, and therefore, even when the screen door and window are inclined with respect to the frame body, the engaging state between the engaging surface portion and the receiving surface portion can be maintained, and accidental movement of the screen door and window can be prevented.

The receiving-side guide surface 52a is a plane inclined to the extending direction B of the right frame 34 so as to gradually become closer to the inner peripheral side as going upward.

The latch base 53 accommodates therein the receiving member 51 in a state where the protective cap 52 is mounted so as to be movable in the up-down direction. In embodiment 1, the latch base 53 includes an outer peripheral base plate portion 53a, two side plate portions 53b, two peripheral plate portions 53c, and a bottom plate portion 53d. The outer Zhou Jiban portions 53a are formed in a substantially square flat plate shape and extend in the depth direction along the up-down direction. The side plate portions 53b extend from both side edge portions of the outer portion Zhou Jiban portion 53a toward the inner peripheral side so as to be substantially parallel to each other, and form a receiving space for the receiving member 51 with the outer portion Zhou Jiban portion 53 a. The side plate portion 53b of embodiment 1 is configured to have a dimension in the vertical direction that is approximately twice that of the outer peripheral base plate portion 53a, and extends so as to protrude upward from the upper end of the outer Zhou Jiban portion 53 a. The distance between the outer surfaces of the two side plate portions 53b is set to be insertable between the two main 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 locking projections 53f are formed on the respective outer surfaces. The guide groove 53e is formed to have a width into which the guide pin portion 51a of the receiving member 51 is inserted, and has a function of guiding the receiving member 51 to move up and down relative to the side plate portion 53b by engagement with the guide pin portion 51 a. When the latch base 53 is disposed between the two main frame plate portions 34b of the right frame 34, the engagement projection 53f abuts against the engagement surface 34c provided on the side plate portion 53 b. The peripheral plate portion 53c extends from a portion of the outer portion Zhou Jiban portion 53a below the side plate portion 53b so as to be curved so as to gradually approach each other toward the inner peripheral side, and when the receiving member 51 is disposed between the side plate portions 53b, the peripheral plate portion 53c is disposed on a circumference centered on the axial center of the spring support pin portion 51 b. The bottom plate portion 53d is bent substantially vertically downward after extending substantially horizontally from the lower edge of the outer portion Zhou Jiban portion 53a toward the inner peripheral side, and has a screw insertion hole 53g at a portion extending downward.

In order to attach the latch unit 50 having the above-described structure to the right frame member 34, the protection cap 52 is accommodated between the side plate portions 53b of the latch base 53 in a state of being attached to the receiving member 51 in advance, and the guide pin portions 51a are respectively arranged in the guide grooves 53e, whereby the tool is arranged to be movable in the up-down direction with respect to the latch base 53. In embodiment 1, by interposing a compression coil spring (urging member) 54 between the lower surface of the receiving member 51 and the bottom plate portion 53d of the latch base 53, the receiving member 51 is maintained in a state of being always urged upward with respect to the latch base 53 by the spring force of the compression coil spring 54. The compression coil spring 54 is configured such that the spring support pin portion 51b of the receiving member 51 is disposed at the upper end portion, and the lower end portion is disposed between the peripheral plate portion 53c and the outer Zhou Jiban portion 53a of the latch base 53, whereby the receiving member 51 can be biased without falling off. The latch unit 50 can be mounted on the right frame member 34 by disposing the latch base 53 between the two front view frame plate portions 34b of the right frame member 34 in this state and further screwing the mounting screw 55 into the frame base 34a via the screw insertion hole 53g of the bottom plate portion 53 d. In this state, the locking projection 53f provided on the side plate 53b abuts against the locking surface 34c of the side plate 53b, and the latch base 53 is prevented from moving toward the outer peripheral side with respect to the right frame 34. The position where the latch unit 50 is mounted is set such that, when the screen door and window 30 is moved to approach the right frame member 13, the engagement guide surface 41j of the engagement protruding piece portion 41h provided below the engagement 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 movement limiting device 1, when the screen door and window 30 is moved from the state shown in fig. 13 (a) toward the right frame member 13, as shown in fig. 13 (b), the engagement guide surface 41j of the lower engagement protruding piece portion 41h provided on the engagement plate portion 41c comes into contact with the receiving side guide surface 52a of the protective cap 52. When the screen door and window 30 is brought closer to the right frame member 13 in this state, as shown in fig. 13 (c), the engagement guide surface 41i and the receiving side guide surface 52a are inclined, so that the operation engagement member 41 and the receiving member 51 are moved appropriately in the up-down direction against the spring force of the tension coil spring 46 and the compression coil spring 54, and are separated from each other. In embodiment 1, since the spring constant of the compression coil spring 54 is set to be large relative to the tension coil spring 46, the operation engagement member 41 of the operation unit 40 moves upward.

When the sliding door 30 continues to move and the contact state between the engaging guide surface 41j and the receiving side guide surface 52a is released, as shown in fig. 13 (d), the operation engaging member 41 and the receiving member 51 move in the direction of approaching each other in the up-down direction due to the spring force of the tension coil spring 46 and the compression coil spring 54, and the engaging surface 41k and the receiving surface 51d face each other. During this time, when the operation engagement member 41 and the receiving member 51 move in the direction to be relatively close to each other, as shown in fig. 12 (b), the engagement side protruding portion 41n of the operation engagement member 41 comes into contact with the introduction guide surface 51g of the receiving member 51. Accordingly, the operation engagement member 41 and the receiving member 51 are appropriately moved in a direction to separate from each other in the horizontal direction by the tilting action of the introduction guide surface 51g, and as shown in fig. 12 (c), the engagement-side protruding portion 41n of the operation engagement member 41 passes over the receiving-side protruding portion 51f of the receiving member 51 to face the receiving surface 51e, and the receiving-side protruding portion 51f of the receiving member 51 faces the engagement surface 41m of the operation engagement member 41. Thus, even if the screen door or window 30 is moved so as to be separated from the right frame member 13, the engagement surface portion 41k of the operation engagement member 41 and the receiving surface portion 51d of the receiving member 51 remain engaged, and movement of the screen door or window 30 is restricted.

Here, for example, the movement limiting device 1 is disposed at a height position of about 1/3 of the total height of the right frame member 13 and the right frame member 34 from the top. In this state, when an operating force is applied at a height of 1/3 or less from below the screen door/window vertical frame 33 located on the left side when viewed from the indoor side to move the screen door/window 30 to the left side, the screen door/window 30 rotates clockwise when viewed from the indoor side with respect to the frame body 10 to assume an inclined posture. Therefore, in the movement limiting device 1, as shown in fig. 12 (d), the receiving member 51 provided to the right frame 34 may be inclined by rotating clockwise with respect to the operation engagement member 41 provided to the right frame 13. However, in the movement limiting device 1 provided in the door and window, as described above, the engaging-side protruding portion 41n provided at the front end portion of the engaging surface portion 41k and the receiving-side protruding portion 51f provided at the front end portion of the receiving surface portion 51d are engaged at positions crossing each other. In other words, the engaging surface portion 41k and the receiving surface portion 51d are engaged with each other in a state of protruding toward each other with respect to the respective base end portions when facing each other. Therefore, even when the screen door and window 30 is in the tilted posture with respect to the frame body 10, there is no risk that the operation engagement member 41 and the receiving member 51 move in the direction in which the right frame member 13 and the right frame member 34 extend in the direction B away from each other, and the engaged state of both can be maintained. This can maintain the state in which the movement of the window and screen 30 with respect to the frame body 10 is restricted, and prevent the window and screen 30 from moving accidentally.

Incidentally, in order to move the screen door and window 30 from the above state, if the operation base 43 is moved upward with respect to the right frame member 13 against the spring force of the tension coil spring 46, the operation engagement member 41 is moved upward with respect to the receiving member 51, and the receiving surface 51d of the receiving member 51 and the engagement surface 41k of the operation engagement member 41 are brought into a non-opposing state. Accordingly, when an operation force is applied to the screen 30 in this state, the screen 30 can be moved relative to the frame body 10.

At this time, according to the movement limiting device 1, as shown in fig. 12 (e), the engagement side release guide surface 41p provided on the engagement surface portion 41k and the receiving side release guide surface 51h provided on the receiving surface portion 51d come into contact with each other with the upward movement of the operation engagement member 41. Therefore, when only the operation base 43 is moved upward, the operation engagement member 41 and the receiving member 51 are appropriately moved in the direction to separate from each other in the horizontal direction by the tilting action of the engagement side release guide surface 41p and the receiving side release guide surface 51h, and the engagement side protruding portion 41n of the operation engagement member 41 is moved upward beyond the receiving side protruding portion 51f of the receiving member 51, so that the operation becomes easy. When the operation force applied to the operation base 43 is removed, the operation engagement member 41 is moved downward by the spring force of the tension coil spring 46. Therefore, the movement of the screen door 30 can be restricted by moving the screen door 30 in the direction approaching the right frame member 13 again.

In embodiment 1, the guide surface 51g is provided only on the receiving member 51, but the present invention is not limited to this, and the guide surface may be provided only on the operation engagement member 41, or may be provided on both the receiving member 51 and the operation engagement member 41. Further, although the release guide surfaces 41p, 51h are provided on both the operation engagement member 41 and the receiving member 51, the release guide surfaces may be provided on only one of the operation engagement member 41 and the receiving member 51. However, the introduction guide surface 51g and the release guide surfaces 41p and 51h are not necessarily provided, and for example, as in modification 1 shown in fig. 14 and modification 2 shown in fig. 15, both the introduction guide surface 51g and the release guide surfaces may be omitted to constitute the movement restriction device.

That is, in modification 1 shown in fig. 14, a boundary surface 141a along the horizontal direction is formed between the engagement side protruding portion 41n of the operation engagement member 141 and the engagement surface 41 m. Similarly, the receiving side protruding portion 51f of the receiving member 151 has boundary surfaces 151a, 151b formed on the upper and lower portions thereof, respectively, in the horizontal direction. In modification 1, the same structures as those in embodiment 1 are denoted by the same reference numerals.

In modification 2 shown in fig. 15, a boundary surface 241a along the horizontal direction is formed between the engagement-side protruding portion 41n of the operation engagement member 241 and the engagement surface 41 m. Further, the engagement surface 41m is extended to the upper end of the lower engagement protruding piece portion 41 h. The receiving side protrusion 51f of the receiving member 251 extends directly to the upper end of the receiving protrusion 51c, and has a boundary surface 251a formed at the lower portion thereof in the horizontal direction. In modification 2, the same arrangement as in embodiment 1 is denoted by the same reference numeral.

In the door and window having the movement restriction device of the modification 1 or modification 2, even when the operation engagement members 141 and 241 and the receiving members 151 and 251 are moved in the direction approaching each other by the spring forces of the tension coil spring 46 and the compression coil spring 54, the following may occur: the distal ends of the operation engagement members 141 and 241 are held in contact with the upper ends of the receiving side protruding portions 51f and the receiving protruding portions 51c, and the engagement surface portions 41k of the operation engagement members 141 and 241 and the receiving surface portions 51d of the receiving members 151 and 251 are not brought into a state of facing each other. However, even if this occurs, when the screen door or window 30 is moved further in the direction approaching the right frame 13 (right side in fig. 14 and 15), as shown in fig. 14 (b) and 15 (b), the contact state between the distal end portions of the operation engagement members 141 and 241 and the upper ends of the receiving side protruding portions 51f is released, and the operation engagement members 141 and 241 and the receiving members 151 and 251 are moved in the direction approaching each other by the spring force of the tension coil spring 46 and the compression coil spring 54, so that the engagement surface portions 41k of the operation engagement members 141 and 241 and the receiving surface portions 51d of the receiving members 151 and 251 are brought into a state facing each other. Therefore, in this state, when the window and door 30 is moved so as to be separated from the right frame member 13, as shown in fig. 14 (c) and 15 (c), the engaging surface portions 41k of the operation engaging members 141 and 241 are engaged with the receiving surface portions 51d of the receiving members 151 and 251, and movement of the window and door 30 can be restricted.

In this state of engagement between the engaging surface 41k of the engaging members 141 and 241 and the receiving surface 51d of the receiving members 151 and 251, the engaging-side protruding portion 41n provided at the front end portion of the engaging surface 41k and the receiving-side protruding portion 51f provided at the front end portion of the receiving surface 51d are positioned at positions crossing each other. In other words, the engaging surface portion 41k and the receiving surface portion 51d are engaged with each other in a state of protruding toward each other with respect to the respective base end portions when facing each other. Therefore, as shown in fig. 14 (d) and 15 (d), even when the screen window 30 rotates clockwise and assumes an inclined posture, the engagement surface 41k of the operation engagement members 141 and 241 and the receiving surface 51d of the receiving members 151 and 251 maintain the engaged state, and the movement of the screen window 30 can be maintained in a restricted state. When the engagement between the engagement surface 41k and the receiving surface 51d is to be released, the screen door or window 30 is brought close to the right frame member 13 and returned to the state shown in fig. 14 (b) and 15 (b), and then the operation engagement members 141 and 241 are moved upward by the operation of the base.

In addition, in each of the above-described embodiment 1, modification 1 and modification 2, the engaging-side protruding portion 41n is provided on the engaging surface portion 41k, and the receiving-side protruding portion 51f is provided on the receiving surface portion 51d, so that the tip end portions of the engaging-side protruding portions protrude toward the other side than the base end portion, but the present invention is not limited thereto. For example, as in modification 3 shown in fig. 16, contact surfaces 341B and 351B inclined with respect to the extending direction B of the right frame 13 and the right frame 34 are provided on the lower engaging projection 341a of the operation engaging member 341 and the receiving projection 351a of the receiving member 351, respectively, to form an engaging surface 341c and a receiving surface 351c. The contact surfaces 341b, 351b are provided so as to gradually protrude toward the other side as they face each other. In modification 3, the contact surface 341b of the engagement surface 341c and the contact surface 351b of the receiving surface 351c are formed at the same inclination angle.

In the door and window provided with the movement limiting device according to modification 3, when the operation engagement member 341 and the receiving member 351 are moved in the direction approaching each other by the spring forces of the tension coil spring 46 and the compression coil spring 54, the engagement surface portion 341c of the operation engagement member 341 and the receiving surface portion 351c of the receiving member 351 are brought into a state of facing each other as shown in fig. 16 (b). Therefore, in this state, even when the screen door and window 30 is moved to be separated from the right frame member 13, the engaging surface portion 341c of the engaging member 341 and the receiving surface portion 351c of the receiving member 351 are operated to maintain the engaged state, and the movement of the screen door and window 30 is restricted.

Further, as shown in fig. 16 (c), even when the screen door or window 30 rotates clockwise with respect to the frame body 10 and assumes an inclined posture, there is no risk that the distal end side will pass over the proximal end side and be located on the inner peripheral side on the receiving surface 351b of the receiving member 351 that has been inclined in advance. Thus, even when the screen door and window 30 is in an inclined posture with respect to the frame body 10, the operation force applied to the screen door and window 30 does not generate a force in a direction to separate the operation engagement member 341 and the receiving member 351 from each other, and the movement of the screen door and window 30 is restricted while maintaining the engaged state.

Embodiment 2

Although in modification 3, the abutment surfaces 341b and 351b are provided on both the engaging surface 341c and the receiving surface 351c, the same effect can be achieved by providing at least one of the front end side of the engaging surface and the front end side of the receiving surface with an abutment surface inclined so as to gradually protrude toward the other side as approaching the front end side.

That is, in embodiment 2 shown in fig. 17, only the receiving surface 451a of the receiving member 451 is provided with an abutment surface 451B inclined with respect to the extending direction B of the right frame 34. The inclination direction of the contact surface 451b is the same as that of modification 3. The engagement surface 441a of the operation engagement member 441 is provided with an engagement surface 441b along the vertical direction. Other configurations are the same as those of embodiment 1, and the same symbols are denoted.

In the door and window provided with the movement limiting device configured as described above, when the operation engagement member 441 and the receiving member 451 move in the direction approaching each other due to the spring force of the extension coil spring 46 and the compression coil spring 54, the engagement surface portion 441a of the operation engagement member 441 and the receiving surface portion 451a of the receiving member 451 are brought into a state of facing each other as shown in fig. 17 (b). Therefore, in this state, even when the screen door and window 30 is moved to be separated from the right frame member 13, the engaging surface portion 441a of the engaging member 441 is operated to maintain the engaged state with the receiving surface portion 451a of the receiving member 451, and the movement of the screen door and window 30 is restricted.

Further, even when the screen window 30 rotates clockwise with respect to the frame body 10 and assumes an inclined posture, as shown in fig. 17 (c), the contact surface 451b of the receiving member 451 that has been inclined in advance comes closer to the vertical direction in the extending direction, and the contact surface 451b that contacts the engagement surface 441b along the vertical direction increases. Thus, the engaging surface 441a of the engaging member 441 is operated to maintain the engaged state with the receiving surface 451a of the receiving member 451, and the movement of the screen door and window 30 is restricted.

In addition, although the above-described embodiment 1, modification 1 to modification 3, and embodiment 2 each exemplify the window and door 30 as a window and door, the window and door 30 is not limited to the window and door 30, and may be applied between another window and door and the frame body 10 as long as it moves along the extending direction of the lateral frame 11. Further, although the movement restriction device is provided between the door window 30 and the right side vertical frame 13 when viewed from the indoor side, the movement restriction device may be provided between the door window 30 and the left side vertical frame 12. Further, although both the operation engagement member and the receiving member are arranged to be movable in the respective extending directions B with respect to the frame member and the frame member, it is sufficient that only one of the operation engagement member and the receiving member is movable. In this case, the urging member may be provided only on the movable member. In addition, although the protective cap is exemplified as the receiving member, the protective cap is not necessarily provided.
