Summary of the Invention

Problems to be Solved by the Invention

[0005] However, with the current configuration of the door body and the mounting frame, there is a risk that a part of the body such as a finger of the person opening and closing the door will be caught when the door body is opened and closed. In particular, when a finger is caught on the hanging side, serious injuries such as fractures or amputations may occur, and there has been a demand for the development of a fitting that fundamentally eliminates the risk of finger entrapment, or a fitting that minimizes the degree of injury even when a finger is caught.

[0006] Furthermore, with regard to joinery, there was a problem in that installation and height adjustment of the door panels were difficult tasks, and there was a need for the development of joinery that could be installed easily and quickly.

[Modes for carrying out the invention]

[0011] Hereinafter, the best embodiment and the like of the fitting according to an embodiment of the present invention will be described with reference to the drawings. Note that the fitting according to the present embodiment is applicable to any fitting as long as it has a form of a hinged door that opens and closes by rotating a door body, and is applicable to a single-leaf door, a double-leaf door, a single-sash door, a double-sash door, a double-hinged door, etc. In the present embodiment, for the sake of explanation, a single-leaf door will be described with reference to it. Further, the fitting according to the present embodiment will typically describe a configuration in which the door opens and closes by rotating the door body by 90 degrees, but it is also applicable to a fitting in which the door opens and closes by rotating the door body by 180 degrees.

[0012] (Schematic Configuration) FIG. 1 shows a schematic front view of an example of the fitting according to the present embodiment, and FIG. 2 shows a schematic top view of an example of the fitting according to the present embodiment.

[0013] As shown in FIG. 1, a door body 120 is attached to a mounting frame 110 having a first vertical frame 112, a second vertical frame 114, an upper frame 116, and a sill 118 in the fitting 100 according to the present embodiment.

[0014] In the present embodiment, the first vertical frame 112 refers to the vertical frame closer to the connecting member 130 (the first connecting member 140 and the second connecting member 150) for attaching the door body 120, and the vertical frame farther from the connecting member 130 is called the second vertical frame 114. Usually, a handle portion 122 is provided at an end portion on the second vertical frame 114 side of the front surface and / or the back surface of the door body 120 to rotate the door body 120. Further, a first door stop 113 and a second door stop 115 that abut against the door body 120 when the door body 120 is closed are provided on the first vertical frame 112 and the second vertical frame 114, respectively.

[0015] In the fitting 100 according to the present embodiment, the upper frame 116 and the door body 120 are connected via the first connecting member 140, and the sill 118 and the door body 120 are connected via the second connecting member 150.

[0016] Detailed configuration examples of the first connecting member 140 and the second connecting member 150 will be described in the embodiments described later, but the first connecting member 140 has a first round bar member 142 that extends vertically (downward) from the end (near) of the upper frame 116 on the first vertical frame 112 side, and the second connecting member 150 has a second round bar member 152 that extends vertically (upward) from the end (near) of the sill 118 on the first vertical frame 112 side.

[0017] Furthermore, the door body 120 has a first round bar receiving recess 124 on its upper surface, i.e., the surface facing the upper frame 116, which engages with the first round bar member 142, and a second round bar receiving recess 126 on its lower surface, i.e., the surface facing the sill 118, which engages with the second round bar member 152. That is, the first round bar receiving recess 124 and the second round bar receiving recess 126 have a circular outer circumference shape when viewed from above.

[0018] The door body 120 is connected to the upper frame 116 via the first connecting member 140, or in other words, via the engagement of the first round bar member 142 and the first round bar receiving recess 124, and is also connected to the sill 118 via the second connecting member 150, or in other words, via the engagement of the second round bar member 152 and the second round bar receiving recess 126.

[0019] Here, Figure 3 shows an enlarged schematic top view of the first vertical frame side of the door fitting according to this embodiment. For explanatory purposes, Figure 3 schematically shows a circular 120a that constitutes a part of the end of the door body 120 on the first vertical frame 112 side in a top view, and a circular 113a that constitutes a part of the first door stop 113. As shown in Figure 3, in this embodiment, in a top view, the center of the first round bar member 142, the center of the second round bar member 152, the center of the first round bar receiving recess 124, and the center of the second round bar receiving recess 126 are all at the same position. Furthermore, in this embodiment, it is preferable that the end of the door body 120 on the first vertical frame 112 side is formed in an arc shape in a top view, and it is preferable that the center of this arc is at the same position as the center of the first round bar member 142. Furthermore, the portion where the first door stopper 113 abuts against the door body 120 is preferably circular in top view, corresponding to the arc shape of the door body 120, and its center is preferably at the same position as the center of the first round bar member 142.

[0020] (effect) The effects of the joinery 100 according to this embodiment will be explained with reference to Figure 3. As mentioned above, in a top view, the joinery 100 according to this embodiment allows the center of the first round bar member 142, the center of the second round bar member 152, the center of the first round bar receiving recess 124, the center of the second round bar receiving recess 126, the center of the circle 120a that constitutes a part of the end of the door body 120 on the first vertical frame 112 side, and the center of the circle 113a that constitutes a part of the first door stop 113 to all be in the same position. Therefore, as shown in Figure 3, the door body 120 can be installed so that there is virtually no gap R between the door body 120 and the first vertical frame 114, so that the user will not get their fingers caught when using the joinery according to this embodiment. In other words, the joinery 100 according to this embodiment is fundamentally configured so that there is no risk of fingers getting caught on the hinge side (first vertical frame 112 side).

[0021] Regarding the shape of the first door stopper 113, there are no particular restrictions as long as a substantial gap R is not created between the door body 120 and the first vertical frame 114, and various shapes can be adopted. Figure 4 shows a schematic top view illustrating an example of a door stopper in the joinery according to this embodiment. For example, a rounded rectangle (see Figure 4(a)), a rectangle (see Figure 4(b)), a triangle (see Figure 4(c)), etc., can be suitably adopted.

[0022] Figure 5 shows a schematic top view illustrating an example of opening and closing the door in the joinery according to this embodiment. Note that in Figure 5, the reference numerals for some components have been omitted for the sake of simplicity in the explanation. Figure 5(a) shows the door 120 in a fully closed state, and through Figures 5(b), 5(c), and 5(d), Figure 5(e) shows the door 120 in a fully open state. As is clear from Figures 5(a) to 5(e), by using the joinery 100 according to this embodiment, there is virtually no gap between the door 120 and the first vertical frame 114 when opening and closing the door 120, so the user's fingers will not get caught. Also, when the door 120 is closed, there is no place for the body to enter between the wall W and the door 120 in the first place, so fingers will not get caught.

[0023] Furthermore, when opening and closing the door 120, there is a risk of fingers getting caught on the second vertical frame 114 side of the door 120, potentially causing fractures or bruises. Therefore, as shown in Figure 2, it is preferable to place cushioning material 160 or the like at the position of the door 120 where it contacts the first door stop 113 when the door 120 is closed, and at the end of the second vertical frame 114 facing the door 120. This makes it possible to reduce the severity of injuries even if fingers get caught on the second vertical frame 114 side of the door 120.

[0024] As described above, the joinery according to this embodiment was typically described in a configuration in which the door opens and closes by rotating the door body 90 degrees, but it is also applicable to joinery in which the door opens and closes by rotating the door body 180 degrees. Figure 6 shows a schematic top view illustrating another example of opening and closing the door body in the joinery according to this embodiment. The upper part of Figure 6 shows the door body when it is closed, and the lower part of Figure 6 shows the door body when it is open. In the joinery configuration shown in Figure 6, there is virtually no gap between the door body 120 and the first vertical frame 114 when the door body 120 is opened and closed, so the user will not get their fingers caught.

[0025] Furthermore, as shown in Figure 6, it is preferable to provide a stopper member 170 on the first vertical frame 112 at a position that contacts the door body 120 when the door body 120 is opened. This prevents fingers from being caught when the door body 120 is opened, and also prevents the door body 120 from colliding with the wall W when the door body 120 is opened.

[0026] (Installation method for the door) Next, a method for installing the door body 120 in the joinery 100 according to this embodiment will be described with reference to Figure 7. Figure 7 shows a flowchart of an example of a method for installing the door body in the joinery according to this embodiment.

[0027] The method for installing the door body in the joinery according to this embodiment is as follows: A door fitting in which a door body is attached to a mounting frame having a first vertical frame, a second vertical frame, an upper frame, and a threshold via a connecting member, and the door can be opened and closed by the rotation of the door body, The connecting member comprises a first connecting member having a first round bar member extending vertically from the end of the upper frame on the first vertical frame side, and a second connecting member having a second round bar member extending vertically from the end of the sill on the first vertical frame side, The door body has a first round bar receiving recess on its upper surface that engages with the first round bar member, and a second round bar receiving recess on its lower surface that engages with the outer circumference shape of the second round bar member. The door body is connected to the upper frame by the first connecting member and to the threshold by the second connecting member. In a top view, the center of the first round bar member, the center of the second round bar member, the center of the first round bar receiving recess, and the center of the second round bar receiving recess are the same, in this method of installing a door body in a joinery. The first step (S100) involves inserting the first round bar member into the first round bar receiving recess to connect the door body and the upper frame, The process includes a second step (S110) of inserting a second round bar member into a second round bar receiving recess to connect the door body and the threshold.

[0028] Each step will be explained in detail. Note that the first step (S100) and the second step (S110) do not need to be performed in this order; the first step (S100) may be performed after the second step (S110).

[0029] The first step (S100), which involves inserting the first round bar member into the first round bar receiving recess to connect the door body and the upper frame, can also be described as the step of connecting the door body to the upper frame via the first connecting member. Typically, since the door body is formed slightly smaller than the mounting frame, the door body is positioned at an angle and the first round bar member of the upper frame is inserted into the first round bar recess.

[0030] If the second step (S110) is performed after the first step (S100), the door body is then pushed up until it contacts the upper frame, forming a gap between the second round bar member and the second round bar receiving recess.

[0031] The second step involves inserting the second round bar member into the second round bar receiving recess to connect the door body and the threshold. This step utilizes the gap between the formed second round bar member and the second round bar receiving recess to insert the second round bar member into the second round bar receiving recess, and simultaneously places the door body on the second round bar member. This connects the door body and the threshold, completing the installation of the door body.

[0032] The method for installing the door body according to this embodiment allows for easy installation of the door body by employing the joinery according to this embodiment as described above.

[0033] Furthermore, the door installation method according to this embodiment may also include a step (S120) for adjusting the height of the door. In this case, as will be explained in detail in the embodiments described later, the height of the door can be easily adjusted by providing a height adjustment configuration on either the first connecting member and / or the second connecting member and / or both of them.

[0034] (First example) Next, specific embodiments of the first and second connecting members will be described with reference to the drawings. Figure 8 shows a schematic front view of an example of the first and second connecting members according to this embodiment.

[0035] The first connecting member 240 shown in Figure 8 is integrally formed with a first round bar member 142 and a plate-shaped member 241 for fixing the first round bar member 142 to the upper frame 116. In the example shown in Figure 8, the first connecting member 240 is fixed to the upper frame 116 by a screw-shaped member 242. As shown by the dashed line in Figure 8, the center of the first round bar member 142, the center of the second round bar member 152, the center of the first round bar receiving recess 124, and the center of the second round bar receiving recess 126 are the same.

[0036] Furthermore, the first round bar receiving recess 124 is connected to the round bar receiving portion 243 via a threaded member 244. The round bar receiving portion 243 is formed to be slightly larger than the first round bar member 142 and slightly smaller than the first round bar receiving recess 124 so as to engage with the outer circumference shape of the first round bar member 142.

[0037] Furthermore, the second connecting member 250 shown in Figure 8 is integrally formed with a second round bar member 152 and a plate-shaped member 251 for fixing the second round bar member 152 to the sill 118, and the second connecting member 250 is fixed to the sill 118 by a screw-shaped member 252.

[0038] In the example shown in Figure 8, the outer surface of the second round bar member 152 of the second connecting member 250 has screw threads for height adjustment, and the outer surface of the second round bar member 152 is provided with a fixing nut 253, a washer 254, and a bearing-integrated nut 255, etc., in order from the bottom.

[0039] The fixing nut 253 is provided to prevent the bearing-integrated nut 255 from shifting position when the door body 120 is opened and closed. The bearing-integrated nut 255 is also provided to adjust the gaps formed at the top and bottom of the door body 120, and its outer diameter is configured to be larger than the outer diameter of the second round bar receiving recess.

[0040] In this embodiment, since the majority of the load of the door body 120 is supported by the upper surface of the bearing-integrated nut 255, the door body 120 can be opened and closed smoothly by the bearing-integrated nut 255.

[0041] Furthermore, a round bar receiving portion 256 is connected to the second round bar receiving recess 126 via a threaded member 257. The round bar receiving portion 256 is formed to be slightly larger than the second round bar member 152 and slightly smaller than the second round bar receiving recess 126 so as to engage with the outer circumference shape of the second round bar member 152.

[0042] (Second example) Figure 9 shows a schematic front view of another example of the second connecting member according to this embodiment.

[0043] The second connecting member 350 shown in Figure 9 is composed of a base 351 that supports the second connecting member, a fixing nut 352 for adjusting the height of the door body 120, and a ball bearing 353.

[0044] The base 351 serves to fix the second connecting member 350 to the sill 118 and to support the second round bar member 150.

[0045] Furthermore, the outer surface of the second round bar member 152 of the second connecting member 350 has screw threads for height adjustment, and the part of the base 351 that contacts the second round bar member 152 is formed in the shape of a nut, so that the height of the second round bar member 152 can be adjusted.

[0046] Furthermore, a fixing nut 352 is provided on the outer surface of the second round bar member 152 to prevent the second round bar member 152 from shifting position due to the rotation of the door body 120.

[0047] In this embodiment, the upper surface of the second round bar member 152 is formed in a dish shape, and a sphere 353 is provided on its upper surface. The sphere 353 acts as a bearing, thereby enabling the door body 120 to open and close smoothly.

[0048] (Third example) Figure 10 shows a schematic front view of another example of the second connecting member according to this embodiment.

[0049] The second connecting member 450 shown in Figure 10 has the same structure as the second connecting member 350 shown in Figure 9, except that it does not have a bearing ball 353.

[0050] In this embodiment, the door body 120 can be opened and closed smoothly by filling the gap between the second round bar receiving portion 256 and the second connecting member 450 with grease (not shown).

[0051] (Fourth embodiment) Figure 11 shows a schematic front view of another example of the first connecting member according to this embodiment.

[0052] The first connecting member 540 shown in Figure 11 has a cylindrical member 541 with one end closed, and an elastic member 542 and the lower end of the first round bar member 142 are housed inside this cylindrical member 541 from below. The first round bar member 142 is configured so that its diameter is slightly larger at the lower end.

[0053] Furthermore, at the other end of the cylindrical member 541, a first flange member 543 is provided, which has an opening slightly larger than the outer circumference of the first round bar member 142 and slightly smaller than the outer circumference of the lower end of the first round bar member 142, so that the first round bar member 142 can move vertically. In other words, it is configured so that the first round bar member 142 cannot slip out of the opening of the first flange member 543. The cylindrical member 541 (and the first round bar member 142) are sized to engage with the first round bar receiving recess, or to put it another way, the cylindrical member 541 and the first flange member 543 also serve as the round bar receiver 243.

[0054] Furthermore, when the door body 120 is attached to the mounting frame 110, the first round bar member 142 has a first opening 544 in the height direction between the first flange member 543 and the round bar receiving portion 243, and when the door body 120 is attached to the mounting frame 110, a second opening 545 is provided in the height direction at a position corresponding to the first round bar receiving recess.

[0055] In this embodiment, when the door body 120 is installed, the cylindrical member 541 (and the elastic member 542 and the first round bar member 142) is inserted into the first round bar receiving recess 124. In this embodiment, the upper frame 116 is provided with an upper frame side first round bar receiving recess 546, and the first round bar member 142 is inserted into the upper frame side first round bar receiving recess 546 by the elastic force of the elastic member 542.

[0056] Figure 12 shows a schematic front view of another example of the second connecting member according to this embodiment. When using the first connecting member 540 shown in Figure 11, the second connecting member does not need to have a height adjustment function. As shown in Figure 12, the second connecting member 550 is configured to have a base 551 that supports the second round bar member 152, the second round bar member 152, and a ball 552 for bearing.

[0057] When attaching the door body 120 to the mounting frame 110 using the connecting member having the first connecting member 540 and the second connecting member 550 according to this embodiment, first, the cylindrical member 541 of the first connecting member 540 is inserted into the first round bar receiving recess 124.

[0058] Then, the door body 120 is tilted so that the sill side is facing forward and the upper frame side is facing backward, and the second round bar member 152 is inserted into the second round bar receiving recess 126.

[0059] Then, with the second opening 545 pushed downward with a predetermined tool, the upper frame side of the door body 120 is moved forward, and the first round bar member 142 is inserted into the first round bar receiving recess 546 on the upper frame side, and the tool is removed from the second opening 545. As a result, the first round bar member 142 is automatically fixed in the first round bar receiving recess 546 on the upper frame side by the elastic force of the elastic member 542.

[0060] Furthermore, when removing the door body 120, first, the first opening 544 is pushed down with a predetermined tool to expose the second opening 545. Then, a predetermined tool is inserted into the second opening 545, and the tool that was inserted into the first opening 544 is removed. By pushing down the tool inserted into the second opening 545, the first round bar member 142 can be removed from the first round bar receiving recess 546 on the upper frame side. Then, the upper frame side of the door body 120 is moved forward, and the second round bar member 152 is removed from the second round bar receiving recess 126, thereby removing the door body 120 from the mounting frame 110.

[0061] (Fifth example) Figure 13 shows a schematic front view of another example of the first connecting member according to this embodiment. The first connecting member 640 shown in Figure 13 has a cylindrical member 641 with one end closed, and an elastic member 642 and the lower end of the first round bar member 142 are housed inside this cylindrical member 641 from below. In this case, the inner diameter of the cylindrical member 641 is configured to be slightly larger than the outer diameters of the first round bar member 142 and the elastic member 642.

[0062] Furthermore, a first flange member 643 for attaching the cylindrical member 641 to the door body 120 is integrally provided with respect to the other end of the cylindrical member 641.

[0063] Furthermore, when the door body 120 is attached to the mounting frame 110, the first round bar member 142 has a first opening 644 in the height direction between the first flange member 643 and the round bar receiving portion 243, and when the door body 120 is attached to the mounting frame 110, a second opening 645 is provided in the height direction at a position corresponding to the first round bar receiving recess.

[0064] In this embodiment, when the door body 120 is installed, the cylindrical member 641 (and the elastic member 642 and the first round bar member 142) is inserted into the first round bar receiving recess 124. In this embodiment, the upper frame 116 is provided with an upper frame side first round bar receiving recess 646, and the first round bar member 142 is inserted into the upper frame side first round bar receiving recess 646 by the elastic force of the elastic member 542.

[0065] In this embodiment, the first flange member 643 is provided with a first screw hole 647, and the first round bar receiving recess 646 is provided with a second screw hole 648, and these are fixed to the door body 120 and the upper frame 116, respectively, by screws (not shown).

[0066] Figure 14 shows a schematic front view of another example of the second connecting member according to this embodiment. The second connecting member 650 shown in Figure 14 is composed of a base 651 that supports the second round bar member 152, a fixing nut 652, the second round bar member 152, a bearing sphere 653, and a round bar receiving portion 256, from the bottom side.

[0067] The base 651 serves to fix the second connecting member 650 to the sill 118 and to support the second round bar member 152. For this purpose, a third screw thread 654 for fixing to the sill 118 is provided on the lower side of the base 651.

[0068] Furthermore, the outer surface of the second round bar member 152 of the second connecting member 650 has screw threads for height adjustment, and the part of the base 651 that contacts the second round bar member 152 is formed in the shape of a nut, so that the height of the second round bar member 152 can be adjusted.

[0069] Furthermore, a fixing nut 652 is provided on the outer surface of the second round bar member 152 to prevent the second round bar member 152 from shifting position due to the rotation of the door body 120.

[0070] In this embodiment, the upper surface of the second round bar member 152 is formed in a dish shape, and a sphere 653 is provided on its upper surface. The sphere 653 acts as a bearing, thereby enabling the door body 120 to open and close smoothly.

[0071] Furthermore, the aforementioned round bar receiving portion 256 is provided on the upper side of the sphere 653. The round bar receiving portion 256 is provided with a fourth screw thread 655 for fixing it to the upper frame 116.

[0072] (Sixth embodiment) Figure 15 shows schematic front views of other examples of the first and second connecting members according to this embodiment. The first connecting member 740 shown in Figure 15 is composed of an upper frame side flange member 741 provided on the upper frame 116 side, a door body side flange member 743 provided on the door body 120 side, a first round bar member 142, and an elastic member 745.

[0073] The upper frame side flange member 741 and the door body side flange member 743 are provided with, for example, an opening in the center that engages with the outer circumference shape of the first round bar member 142, and are configured to support the first round bar member 142 through this opening.

[0074] Furthermore, the upper frame side flange member 741 and the door body side flange member 743 are fixed to the upper frame 116 and the door body 120, respectively, via threaded members 741 and 743.

[0075] In this embodiment, an elastic member 745 is provided on the lower side of the first round bar member 142, and the elastic force of the elastic member 745 ensures that the first round bar member 142 is reliably positioned within the openings of the upper frame side flange member 741 and the door body side flange member 743.

[0076] Furthermore, the first round bar member 142 is provided with a first opening 746 in the height direction corresponding to the upper frame side flange member 741 when the door body 120 is attached to the mounting frame 110, and a second opening 747 is provided in the height direction between the upper frame side flange member 741 and the door body side flange member 743 when the door body 120 is attached to the mounting frame 110.

[0077] Furthermore, the second connecting member 750 shown in Figure 15 is composed of a sill-side flange member 751, a second round bar member 152, and a round bar receiving portion 752.

[0078] The sill-side flange member 751 serves as a base for supporting the second round bar member 152 and is fixed to the sill 118, for example, via a threaded member 753. In this embodiment, the upper end of the second round bar member 152 is formed in a hemispherical shape, thereby allowing the door body 120 to open and close smoothly. The sill-side flange member 751 may be integrally formed with the second round bar member 152, or it may be a separate component that is fixed to it.

[0079] When attaching the door body 120 to the mounting frame 110 using the connecting member having the first connecting member 740 and the second connecting member 750 according to this embodiment, first, the upper frame side flange member 741, the door body side flange member 743, and the sill side flange member 751 are fixed to the upper frame 116, the door body 120, and the sill 118, respectively. Then, the door body 120 is tilted so that the sill side is facing forward and the upper frame side is facing backward, and the second round bar member 152 is inserted into the round bar receiver 752.

[0080] Then, the first round bar member 142 (and elastic member 745) is inserted into the opening of the door body side flange member 743, and while the first opening 746 is pushed down with a predetermined tool, the upper frame side of the door body 120 is moved forward, and the first round bar member 142 is inserted into the opening of the upper frame side flange member 741, and the tool is removed from the first opening 746. As a result, the first round bar member 142 is automatically supported by the opening of the upper frame side flange member 741 due to the elastic force of the elastic member 745.

[0081] Furthermore, when removing the door body 120, first, the second opening 747 is pushed down with a designated tool to expose the first opening 746. Then, a designated tool is inserted into the first opening 746, and the tool that was inserted into the second opening 747 is removed. By pushing down the tool inserted into the first opening 746, the first round bar member 142 can be removed from the upper frame side flange member 741. Then, the upper frame side of the door body 120 is moved forward, and the second round bar member 152 is removed from the round bar receiver 752, thereby removing the door body 120 from the mounting frame 110.

[0082] (Cosmetic film) Figure 16 shows a schematic top view of a door body to illustrate a method for applying a decorative film to the door body of a building fixture according to this embodiment. It is preferable to adhere an adhesive decorative film having an adhesive layer on its back surface to the door body for the purpose of improving the appearance of the door body or for the purpose of providing predetermined functions such as fire resistance and weather resistance.

[0083] However, as described above, in this embodiment, it is preferable that the end on the vertical frame side of the door body be formed in an arc shape when viewed from above. Therefore, as shown in Figure 16(a), the boundary between the decorative film 800a on the first surface 120a side and the decorative film 800b on the second surface 120b side of the door body 120 is curved when viewed from above, making the decorative film prone to peeling off.

[0084] Therefore, as shown in Figure 16(b), it is preferable to provide an opening 806 in the arc of the door body 120, to attach decorative film 800a and decorative film 800b up to the wall surface of the opening 806, to provide a stopper member 802 in the opening 806, and further to provide a nail-shaped member 804 to fix the stopper member 802 inside the opening 806. This prevents the decorative film 800a and decorative film 800b from peeling off.
