DETAILED DESCRIPTION OF THE INVENTION

[0008] The inventors of the present application have studied fittings with sliding doors, such as storm shutters, and have come to the following new realization. For example, in the case of storm shutters that store door bodies (panels) in a door pocket, when unfolding the door bodies to cover the exterior side of a window, the user inserts their hands into the door pocket and pulls out and moves multiple door bodies in order. This work involves the complicated and time-consuming action of pulling out multiple door bodies from the door pocket. It is also not easy to pull door bodies on the exterior side (rear side) of the door pocket toward the interior side by hand.

[0009] When storing the deployed door bodies in a door pocket, the multiple door bodies are moved into the door pocket in order and pushed from the indoor side (front side) of the door pocket to the outdoor side (rear side). This work involves moving the door bodies in a front-to-rear direction, which is perpendicular to the lateral direction in which the door rollers are easily moved, so there is a large frictional resistance and a heavy burden on the worker. Below, we will explain a technology for fittings that can easily deploy and store multiple door bodies with reference to embodiments.

[0010] An example of an embodiment will be described below. Identical components will be assigned the same reference numerals, and redundant explanations will be omitted. In each drawing, some components will be omitted, enlarged, or reduced as appropriate for ease of explanation. The drawings should be viewed according to the orientation of the reference numerals. The structures and shapes referred to in this specification include not only structures and shapes that strictly match the contents referred to, but also structures and shapes that deviate by errors such as dimensional errors and manufacturing errors. In each drawing, some components that are not important for explaining the embodiment will be omitted.

[0011] Terms including ordinal numbers such as "first" and "second" are used to describe various components. These terms are used only to distinguish one component from another, and do not limit the configuration of the present disclosure. The following embodiments are provided as examples to help understand the contents of the present disclosure, and do not limit the configuration of the present disclosure.

[0012] [Embodiment] Please refer to Figures 1 to 9. An embodiment of the present disclosure is a fitting 10. The fitting 10 is suitably installed as a storm shutter that is installed to cover the outdoor side of a window in a building. As shown in Figures 1 and 2, the fitting 10 of the embodiment comprises a first door body 1, a second door body 2, and a connecting mechanism 3 that connects the first door body 1 to the second door body 2. When the first door body 1 and the second door body 2 are connected and one of them is moved laterally, the other also moves laterally. Hereinafter, the horizontal movement may be referred to as "slide." When the first door body 1 and the second door body 2 are collectively referred to as simply the door body, the following figures may be shown partially cut away.

[0013] The change in posture of the fitting 10 from the first state to the third state will now be explained. The first state shown in Figures 1 and 2 is a state in which the first door body 1 is stacked in front of the second door body 2 in the front-to-back direction. In this state, both door bodies can be stored in the door pocket 7. The state in which the first door body 1 is stacked in front of the second door body 2 and stored in the door pocket 7 is called the stored state.

[0014] The second state shown in Figures 3 and 4 is a state in which the first door body 1 and the second door body 2 are lined up horizontally. In this example, the first door body 1 is lined up at the door tip side of the second door body 2. In this state, the first door body 1 is pulled out from the door pocket 7, and the second door body 2 is still housed within the door pocket 7. This state is called the intermediate state. In the third state shown in Figure 5, the first door body 1 and the second door body 2 are lined up horizontally and both have been pulled out from the door pocket 7. This state is called the deployed state. Note that in the following figures, the arm support member 38 in a plan view may be shown by its outline.

[0015] Hereinafter, for convenience, the vertical direction along the top and bottom of the door body will be referred to as the "vertical direction," and the horizontal direction along the left and right of the door body will be referred to as the "lateral direction." The lateral direction is the sliding direction of the door body. In the lateral direction, the sliding direction when unfolding is simply referred to as the "sliding direction," and the opposite direction will be referred to as the "counter-sliding direction." The direction along the thickness of the door body will be referred to as the "front-to-back direction." In the front-to-back direction, the direction from the outdoor side to the indoor side will be referred to as the "front" or "forward," and the opposite side will be referred to as the "rear" or "rearward." These directional notations do not limit the usage orientation of the door 10; the door 10 can be used in any orientation. The lateral dimension will sometimes be referred to as the "width," the vertical dimension as the "vertical width," and the front-to-back dimension as the "front-to-back width." When the door 10 moves laterally when unfolding, the front end of the door body will be referred to as the "door tip," and the rear end of the door body will be referred to as the "door tail." Therefore, when moving laterally when storing, the door tail will be the front and the door 10 will be the rear.

[0016] Refer to Figures 3 and 4. The first door body 1 has a door body main body 14, a connecting mechanism 3, and a ball mechanism 6. The door body main body 14 has a panel 15, an upper frame 16, a lower frame 17, and vertical frames 18 and 19. The upper frame 16, the lower frame 17, and the vertical frames 18 and 19 form a rectangular frame that surrounds the panel 15 and supports the panel 15. The vertical frame 18 is a door end frame provided at the door end 11, and the vertical frame 19 is a door end frame provided at the door end 12. The connecting mechanism 3 is a mechanism for connecting the first door body 1 to the second door body 2.

[0017] The second door body 2 has a door body main body 24, a guide groove 5 extending in the longitudinal direction (horizontal direction) on the top surface of the second door body 2, and a ball mechanism 6. The door body main body 24 has a panel 25, an upper frame 26, a lower frame 27, and vertical frames 28 and 29. The upper frame 26, the lower frame 27, and the vertical frames 28 and 29 form a rectangular frame that surrounds the panel 25 and supports the panel 25. The vertical frame 28 is a door end frame provided at the door end 21, and the vertical frame 29 is a door end frame provided at the door end 22.

[0018] The first door body 1 has an arm support member 38 attached to the top surface of the upper frame 16, and a ball mechanism support member 68 attached to the bottom surface of the lower frame 17. The second door body 2 has a groove forming member 58 attached to the top surface of the upper frame 26, and a ball mechanism support member 68 attached to the bottom surface of the lower frame 27. The arm support member 38, groove forming member 58, and ball mechanism support member 68 are collectively referred to as the adapter 8. As shown in Figure 7, the adapter 8 has the same width and front-to-back width as the upper and lower frames, and is a thin member in both the vertical direction.

[0019] 6 and 7, arm support member 38 has a protrusion 385 that protrudes downward and fits into recess 72 provided in the upper surface of upper frame 16, and groove forming member 58 has a protrusion 585 that protrudes downward and fits into recess 72 provided in the upper surface of upper frame 26. Ball mechanism support member 68 has a protrusion 685 that protrudes upward and fits into recess 74 provided in the lower surfaces of lower frame 17 and lower frame 27.

[0020] 6 is a vertical cross-section taken along line AA in FIG. 2. As shown in this figure, the connecting mechanism 3 has an arm member 32 rotatably supported on the first door body 1, and an engaging member 34 provided at the movable end of the arm member 32. The arm member 32 has a through-hole 35 on the base end side. The arm support member 38 has an upper step portion 381, a middle step portion 382 that is one step lower than the upper step portion 381, and a tapped hole 383 formed in the middle step portion 382. In this example, the middle step portion 382 has a front-to-rear width that is approximately 50% of the front-to-rear width of the first door body 1, and a horizontal width that is approximately equal to the front-to-rear width. The middle step portion 382 extends from the front-to-rear center to the rear end of the first door body 1, and extends laterally to the end on the door trailing edge side.

[0021] The tip of the bolt 36 passes through the washer 37 and the through-hole 35 and is screwed into the tapped hole 383. With this configuration, the arm member 32 is attached to the arm support member 38 so as to be rotatable around the bolt 36. The engaging member 34 is a pin member that protrudes downward from the movable end of the arm member 32 and has a circular cross section in a plan view. The engaging member 34 and the arm member 32 are formed integrally. When attached to the arm support member 38, the arm member 32 may protrude above the upper step 381, but in this example, it is fitted into the range below the upper step 381.

[0022] As shown in FIG. 2 , the engagement member 34 slidably engages with the guide groove 5 that extends in the longitudinal direction of the upper surface of the second door body 2. The groove-forming member 58 has an upper step 581 and a middle step 582 that is one step lower than the upper step 581. In this example, the middle step 582 extends laterally and has a front-to-rear width that is approximately 50% of the front-to-rear width of the second door body 2, and is formed from the front-to-rear center to the front end of the second door body 2. The guide groove 5 is formed in the middle step 582. The height of the middle step 582 of the groove-forming member 58 is equal to the height of the middle step 382 of the arm support member 38.

[0023] As shown in FIG. 2 , the guide groove 5 includes a first groove portion 51 and a second groove portion 52. The first groove portion 51 extends from a base end 511 on the door tail 22 side toward an extended end 512 on the door tip 21 side. The first groove portion 51 may be curved, but in this example, it extends linearly along the front-to-rear center of the middle section 582. The first groove portion 51 is located forward of the front-to-rear center line of the second door body 2. The second groove portion 52 extends diagonally rearward from the extended end 512 of the first groove portion 51. The second groove portion 52 may extend linearly, but in this example, it extends along a convex curve facing diagonally forward. The groove width of the guide groove 5 is set by adding a margin to the outer shape of the engaging member 34 to allow the engaging member 34 to slide.

[0024] As shown in Figure 7, the door body has two ball mechanisms 6 arranged at a predetermined interval in the horizontal direction. The ball mechanism 6 has a spherical ball 62, a rectangular parallelepiped ball receiving portion 63 that receives the ball 62, and a cylindrical protrusion 64 that protrudes upward from the ball receiving portion 63. The ball receiving portion 63 has a receiving space that rotatably receives the ball 62. When received in the ball receiving portion 63, the ball 62 protrudes downward to support the door body from below. The dimensions of the receiving space of the ball receiving portion 63 are set by adding a margin to the outer shape of the ball 62 to allow rotation of the ball 62. The ball mechanism 6 is fitted into a recess 686 that recesses upward from the underside of the ball mechanism support member 68. Because the ball 62 is allowed to rotate in all directions, frictional resistance can be reduced when the door body moves laterally and forward and backward.

[0025] 2 and 8, the change in posture during the unfolding operation of the fitting 10 will be described. In the unfolding operation, the user applies force to the door body in the sliding direction, causing the fitting 10 to move from the first state to the second state and then to the third state. As shown in FIG. 2, in the first state, the first door body 1 overlaps in front of the second door body 2. At this time, the arm member 32 has rotated diagonally backward and left, and the engaging member 34 is positioned near the base end 511 of the first groove portion 51.

[0026] When a force S is applied to the first door body 1 in the sliding direction (leftward in the figure) from the first state, the first door body 1 moves toward the door edge, and the engaging member 34 moves in the sliding direction in the first groove portion 51 as shown in FIG. 8(A). At this time, the engaging member 34 moves while abutting against the front edge 513 of the first groove portion 51. When the first door body 1 is further moved in the sliding direction, the engaging member 34 moves from the first groove portion 51 to the second groove portion 52, and as shown in FIG. 8(B), the engaging member 34 moves diagonally backward in the second groove portion 52 while abutting against the slope 522 on the door edge side of the second groove portion 52.

[0027] When a force S in the sliding direction is applied to the first door body 1 with the engaging member 34 in contact with the slope 522, a component force F of that force is applied to the slope 522. As a result, the door edge side of the second door body 2 moves diagonally forward due to the component force F, and at this time, the second door body 2 is pulled out of the door pocket 7, reaching the second state shown in Fig. 8(C). Furthermore, when a force S in the sliding direction is applied to the first door body 1 in the state of Fig. 8(C), the second door body 2 follows the first door body 1 and moves in the sliding direction as shown by the arrow P, reaching the third state shown in Fig. 4.

[0028] As shown in Figure 8, when the posture of the first door body 1 and the second door body 2 changes, the rear corner of the door tail 12 of the first door body 1 may interfere with the front corner of the door tip 21 of the second door body 2. Therefore, in this embodiment, at least one of the door tail 12 of the first door body 1 and the door tip 21 of the second door body 2 is provided with a relief portion 213 to avoid interference with the other when the posture of the door body changes.

[0029] In the example of Figure 8, the recess 213 includes an inclined portion 214 formed by receding the front corner of the door edge 21 of the second door body 2. In this example, the inclined portion 214 is inclined diagonally forward from the door edge 21. The inclined portion 214 may have a linear outer shape in a plan view, but in this example, it has an outer shape that follows a convex curve that is diagonally forward in a plan view.

[0030] 9 and 2, the change in posture during the retracting operation of the fitting 10 will be described. During the retracting operation, the user applies a force R to the door body in the counter-slide direction, causing the fitting 10 to move from the third state to the second state and then to the first state.

[0031] In the process from the second state to the first state, the door body goes through the processes shown in Figures 9(A) and 9(B). In the second state, when a force R in the counter-slide direction is applied to the first door body 1, the first door body 1 moves toward the door tail end, and the engaging member 34 moves diagonally forward in the second groove portion 52 while abutting against the inclined surface 524 on the opposite side to the door tip 21 of the second groove portion 52.

[0032] When a force R in the counter-sliding direction is applied to the first door body 1 with the engaging member 34 in contact with the slope 524, a component force G of the force R is applied to the slope 524. As a result, the door tip side of the second door body 2 moves diagonally backward due to the component force G. As a result, the second door body 2 moves around to the rear side of the first door body 1, reaching the state shown in FIG. 9(B). Furthermore, when a force R in the counter-sliding direction is applied to the first door body 1, the engaging member 34 moves in the counter-sliding direction while in contact with the rear edge 514 of the first groove portion 51. At this time, a component force G of the force R is applied to the rear edge 514. As a result, the second door body 2 is pushed into the rear door pocket 7, reaching the first state shown in FIG. 2.

[0033] The features of the fitting 10 configured as above will now be described. The fitting 10 comprises a first door body 1, a second door body 2, and a connecting mechanism 3 that connects the second door body 2 to the first door body 1. The connecting mechanism 3 has an arm member 32 that is rotatably supported on the first door body 1, and an engaging member 34 that is provided at the movable end of the arm member 32. The engaging member 34 slidably engages with a guide groove 5 that is on the top surface of the second door body 2 and extends in the longitudinal direction thereof.

[0034] With this configuration, by moving one of the first door body 1 and the second door body 2, the other can be moved together. This makes it easy to unfold and store multiple door bodies, reducing the burden on the user.

[0035] In this embodiment, when the first door body 1 is moved in the door leading direction in the first state where the first door body 1 is stacked in front of the second door body 2, the engaging member 34 moves the guide groove 5 in the door leading direction, and the first door body 1 and the second door body 2 are lined up side by side, resulting in a second state. Furthermore, when the first door body 1 is moved in the door trailing direction in the second state, the engaging member 34 moves the guide groove 5 in the door trailing direction, and the first state is reached. In this case, the burden on the user during the door body unfolding and retracting operations can be reduced.

[0036] In this embodiment, the guide groove 5 includes a first groove portion 51 extending from the door trailing edge side to the door leading edge side, and a second groove portion 52 extending diagonally rearward from an extending end 512 of the first groove portion 51. In this case, the second door body 2 can be moved back and forth by moving the first door body 1.

[0037] In this embodiment, the guide groove 5 is formed in a groove forming member 58 attached to the upper frame 26 of the second door body 2. In this case, by attaching the groove forming member 58, on which the guide groove 5 is formed in advance, to the door body, the number of work steps on site can be reduced.

[0038] In this embodiment, the arm member 32 is supported by an arm support member 38 attached to the upper frame 16 of the first door body 1. In this case, by attaching the arm support member 38, into which the arm member 32 has been pre-assembled, to the door body, the amount of work required on site can be reduced.

[0039] In this embodiment, the second door body 2 is equipped with a ball mechanism 6 having a ball 62 that supports the door body from below. The ball 62 protrudes downward and is supported rotatably. In this case, the provision of the ball mechanism 6 reduces frictional resistance in the lateral and front-to-rear movement of the door body, improving usability.

[0040] In this embodiment, the ball mechanism 6 is supported by a ball mechanism support member 68 attached to the bottom frame 27 of the second door body 2. In this case, by attaching the ball mechanism support member 68, into which the ball mechanism 6 is pre-installed, to the door body, the number of work steps on site can be reduced.

[0041] In this embodiment, at least one of the first door body 1 and the second door body 2 is provided with a clearance 213 to avoid interference with the other door body when the door body changes position. In this case, the operation when changing the position of the first door body 1 and the second door body 2 becomes smooth.

[0042] The above is a description of the embodiment.

[0043] The following describes modified examples. In the drawings and descriptions of the modified examples, the same or equivalent components and members as those in the embodiment are denoted by the same reference numerals. Explanations that overlap with the embodiment will be omitted as appropriate, and the description will focus on the configurations that differ from the embodiment.

[0044] A modified example of the guide groove 5 will be described with reference to Figure 10. The guide groove 5 of this modified example differs from the embodiment in that it has a third groove portion 53 in addition to the first groove portion 51 and the second groove portion 52, but the other configurations are similar. Therefore, redundant explanations will be omitted and the description will focus on the third groove portion 53. The third groove portion 53 extends rearward from the extended end 526 of the second groove portion 52. In this case, the engaging member 34 abuts against the edge of the third groove portion 53 substantially perpendicularly, so that the force of moving it in the lateral direction can be efficiently transmitted.

[0045] [Other variations] In the description of the embodiment, an example has been shown in which the inclined portion 214 does not come into contact with the door end 12 of the first door body 1 during the process of changing the position of the door body, but this is not limiting. The inclined portion may come into contact with the first door body during the process of changing the position, or may be configured to guide the first door body during the process of changing the position.

[0046] In the description of the embodiment, an example has been shown in which the engaging member 34 and the arm member 32 are integrally formed, but this is not limiting. The engaging member 34 and the arm member 32 may also be formed separately and then joined together.

[0047] In the description of the embodiment, an example in which the ball mechanism 6 is provided on both the first door body 1 and the second door body 2 has been shown, but this is not limiting. The ball mechanism may be provided on one door body and not on the other door body.

[0048] In the description of the embodiment, an example was shown in which the fitting 10 is composed of two door bodies, the first door body 1 and the second door body 2, but this is not limited to this. The fitting may be composed of three or more door bodies. In this case, the middle door body may have a guide groove extending laterally and a connecting mechanism provided on the door end side.

[0049] Any combination of the above components is also valid as an aspect of the technical idea that abstracts the embodiment and the modified examples. For example, any description of another embodiment may be combined with the embodiment, or any description of an embodiment and another modified example may be combined with the modified example.

[0050] The above describes the embodiments and modifications. When understanding the abstract technical concepts of the embodiments and modifications, the technical concepts should not be interpreted as being limited to the contents of the embodiments and modifications. The above-described embodiments and modifications are merely illustrative examples, and many design modifications, such as changes, additions, and deletions of components, are possible. In the embodiments, the content in which such design modifications are possible is emphasized by adding the notation "embodiment." However, design modifications are also permitted even in content without such notation. Hatching on cross sections in the drawings does not limit the material of the hatched object.
