Description

[Technical Field]

[0001] The present invention relates to a sliding door. [Background technology]

[0002] Conventionally, some sliding doors suspended on an upper rail are equipped with a soft-close mechanism to reduce the impact and noise caused by the door panel hitting the opening frame or door stop. The soft-close mechanism operates when a trigger fixed to the upper rail catches on a receiving part formed on the soft-close mechanism of the door panel, reducing the movement speed of the door panel when the sliding door is opened or closed, and guiding it to the fully open or fully closed position.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-115419 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the soft-close mechanism may not operate properly due to deformation of the trigger.

[0005] Therefore, an object of the present invention is to provide a sliding door that suppresses deformation of the trigger and allows the soft-close mechanism to operate appropriately. [Means for solving the problem]

[0006] A first sliding door that solves the above problem comprises an upper rail that opens downward, a panel body that moves along the upper rail, a soft close mechanism formed on the upper edge of the panel body, and a trigger device fixed to the inside of the upper rail, wherein the trigger device has a fixed part that is fixed to the upper rail and a protruding part that protrudes from the fixed part and hooks onto a receiving part of the soft close mechanism as the panel body moves, and the protruding part is box-shaped with a rectangular protruding end face and four side faces that connect each side of the protruding end face to the fixed part.

[0007] The second sliding door is the first sliding door, wherein the protruding portion has corners formed by the protruding end surface and the four side surfaces, each of which is formed by a curved surface.

[0008] The third sliding door is provided with a bounce-up prevention plate above the end of the panel body in the traveling direction when the receiving portion contacts the protruding portion in the first or second sliding door, and extending downward from the upper rail.

[0009] The fourth sliding door is the third sliding door, wherein the upper rail is provided with a running section along which a hoisting wheel that suspends the upper edge of the panel body can run, and the bounce-up suppression plate is provided above the hoisting wheel on the side of the panel body that is moving in the direction of travel when the receiving section contacts the protrusion.

[0010] A fifth sliding door is the third or fourth sliding door, wherein the bounce-suppression plate is made of synthetic resin foam.

[0011] A sixth sliding door is the fifth sliding door, wherein the bounce-up suppression plate is adhesively fixed to the upper rail.

[0012] A seventh sliding door is the fifth or sixth sliding door, in which the bounce-up suppression plate is integrally formed.

[0013] The eighth sliding door is a sliding door according to the fourth to seventh embodiments, wherein the upper rail has a pair of side panels extending in the lengthwise direction and a pair of running portions extending from the side panels in directions approaching each other, and the side panels each have a hanging portion extending downward beyond the running portion, and the upper edge of the panel body is inserted between the hanging portions. [Effects of the Invention]

[0014] According to the first sliding door, the protrusion of the trigger device that hooks onto the receiving portion of the soft close mechanism is box-shaped with a rectangular protruding end face and four side faces that connect each side of the protruding end face to the fixed portion, which increases the strength of the protrusion, suppresses deformation of the trigger device, and prevents malfunctions when the soft close mechanism is activated.

[0015] According to the second sliding door, the corners between the protruding end face of the protrusion and the four side faces are each formed as curved surfaces, which makes it easier for the protrusion to fit into the receiving part of the soft-close mechanism and allows the soft-close mechanism to move smoothly when it is activated. Also, since there are no pin angles, damage to the protrusion and receiving part is suppressed, stress concentration at the corners is prevented, and deformation of the protrusion can be more effectively suppressed.

[0016] With the third sliding door, when the receiving portion and the protruding portion of the panel body collide during the opening and closing operation, a force is generated in the direction in which the panel body moves forward, causing the panel body to bounce upward. However, by forming a bounce-up prevention plate, the panel body can be prevented from bouncing up.

[0017] According to the fourth sliding door, the bounce-suppression plate is provided above the hoist wheel at the position where the receiving portion and the protruding portion come into contact, so when the panel body bounces up, the hoist wheel comes into contact with the bounce-suppression plate, thereby suppressing the panel body from bouncing up. Therefore, compared to the panel body itself or the soft-close mechanism, the flexible hoist wheel collides with the bounce-suppression plate, reducing vibrations when it collides with the bounce-suppression plate. Also, damage caused by collisions can be suppressed.

[0018] According to the fifth sliding door, the bounce-up suppression plate is made of synthetic resin foam, so when the panel body bounces up, it can prevent damage to parts that collide with the bounce-up suppression plate and can suppress vibrations and noise caused by the collision.

[0019] According to the sixth sliding door, the bounce-prevention plate is adhesively fixed to the upper rail, making installation easy.

[0020] According to the seventh sliding door, the bounce-suppression plate is integrally molded, which reduces the number of parts and simplifies the installation process.

[0021] According to the eighth sliding door, the pair of side panels, the pair of running portions, and the hanging portion extending downward from the running portions make it difficult to see the inside of the upper rail even when the sliding door is open, so the trigger device and the bounce-up prevention plate are not visible, improving the design.

[0023] Hereinafter, an embodiment of a sliding door of the present invention will be described with reference to the drawings. The sliding door 1 is an indoor fixture installed in a building such as a house, and opens and closes the boundary between rooms by sliding a panel body 3 laterally. The sliding door 1 is not limited to a so-called single sliding door, but may be a sliding door in which the panel body 3 is retracted into a door pocket, or a double sliding door in which multiple panel bodies 3 slide in two directions. Furthermore, the sliding door 1 is not limited to an indoor fixture, but may also be an outdoor fixture or storage fixture, or a sliding door 1 used to open and close various pieces of furniture.

[0024] <About the structure of each part of the sliding door> 1 to 3, the sliding door 1 comprises an upper rail 2 provided along a ceiling surface 5, a panel body 3 movable along the upper rail 2, a soft-close mechanism 4 formed on the upper edge of the panel body 3, a trigger device 6 fixed inside the upper rail 2, a bounce-suppression plate 7 fixed inside the upper rail 2, two hoisting wheels 8a and 8b that hoist the upper edge portion 33 of the panel body 3, and a support roller 10 connected to the end of the soft-close mechanism 4. The sliding door 1 also has a lower rail 12 provided on a floor surface 11 below the panel body 3, and a door roller 13 that can run along the lower rail 12 at the lower end of the panel body 3.

[0025] The upper rail 2 is formed as a long steel groove that opens downward as shown in Figures 4 and 5, and has an upper plate 20 that is fixed to the ceiling surface 5 with screws not shown, a pair of side plates 21 formed downward from both side edges of the upper plate 20, and a pair of running portions 22 that extend from the pair of side plates 21 in directions approaching each other.

[0026] The upper plate 20 bulges upward at its widthwise center and abuts against the ceiling surface 5, with shallow groove-like recesses formed on both sides. A pair of side plates 21 hangs downward from both side edges of the upper plate 20, and a pair of rungs 22 protrude from the opposing surfaces of the pair of side plates 21 toward each other in the vertically middle portion of the side plates 21. The side plates 21 are formed with hanging portions 23 that extend downward beyond the rungs 22. The pair of rungs 22 are each formed flat on the side closer to the side plate 21, and the sides of the pair of rungs 22 that approach each other are curved so as to bulge downward. A gap is formed between the pair of rungs 22, and a connection portion 81 fixed to the upper edge 33 of the lower panel body 3 passes through the gap and is connected to the hoisting wheels 8a and 8b, thereby suspending the panel body 3.

[0027] 1 to 3, the panel body 3 is formed by a rectangular frame 30 and a transparent or semi-transparent face material 31 arranged inside the rectangular frame 30. Cushioning materials 32 are fitted into the side surfaces of the panel body 3, which form the door trailing edge and door leading edge, respectively, to reduce the impact when the panel body 3 collides with an opening frame (not shown). Note that the panel body 3 is not limited to the configuration described above, and the panel body 3 may not have the transparent or semi-transparent face material 31.

[0028] 1, 2, and 8, the soft-close mechanism 4 slides inside the upper rail 2 in accordance with the opening and closing movement of the panel body 3, and when the sliding door 1 is fully closed or fully open, applies a braking force to the panel body 3 to pull the panel body 3 to the fully closed or fully open position. Although not shown, the soft-close mechanism 4 has a braking device such as an air damper for slowing the movement of the panel body 3, and a spring member for pulling the panel body 3 to the fully closed or fully open position.

[0029] Slide holes 40 are formed on both ends of the upper surface of the soft close mechanism 4, extending along the length of the soft close mechanism 4. Receiving portions 41 are formed so as to protrude upward from the slide holes 40. The receiving portions 41 are formed to be slidable relative to the slide holes 40. The receiving portions 41 are biased by a braking device and a spring member (not shown). The receiving portions 41 are supported so as to be swingable on a shaft (not shown) inside the soft close mechanism 4, and are formed with an engagement notch 42 that engages with a protrusion 60 of the trigger device 6 (described later).

[0030] When the protrusion 60 of the trigger device 6 fixed to the upper rail 2 catches on the receiving portion 41, the engagement notch 42 of the receiving portion 41 swings to pinch the protrusion 60, thereby unlocking the receiving portion 41. The unlocked receiving portion 41 moves from one end to the other end of the slide hole 40 due to the bias of a spring member (not shown), but the movement of the receiving portion 41 is slowed by a braking device (not shown). At this time, the receiving portion 41 is fixed to the protrusion 60 and is stopped, so that the receiving portion 41 slowly moves through the slide hole 40 from one end to the other, and the soft-close mechanism 4 other than the receiving portion 41 moves slowly together with the panel body 3 to the fully closed or fully open position.

[0031] The soft-close mechanism 4 of this embodiment is a double-sided soft-close mechanism 4 that operates in both the fully closed and fully open positions. The soft-close mechanism 4 is not limited to the one described above, and various known soft-close mechanisms 4 can be used. The soft-close mechanism 4 is long, inserted inside the upper rail 2, and one end is supported by one of the hoisting wheels 8a, and the other end is supported by a support roller 10 shaped similarly to the wheel 80 of the hoisting wheel 8a.

[0032] As shown in Figures 6 and 7, the trigger device 6 is formed as a single unit by pressing a metal plate. The trigger device 6 has a fixed portion 61 formed in a flat plate shape and fixed to the upper rail 2, a protruding portion 60 formed in the center in the longitudinal direction and protruding from the fixed portion 61, and a rising portion 62 formed rising from the side edge of one end of the fixed portion 61. The fixed portion 61 has through holes 63 formed on both sides of the protruding portion 60, and screws 64 are inserted into the through holes 63 to fix the trigger device 6 to the underside of the upper plate 20. The other end of the fixed portion 61 is formed to be pointed toward the tip, which indicates the installation direction when fixing the trigger device 6 to the upper plate 20.

[0033] The protruding portion 60 is hollow and has a shape that allows the receiving portion 41 of the soft-close mechanism 4 to hook onto it. The protruding portion 60 is box-shaped and has a rectangular protruding end surface 65 and four side surfaces 66 that connect each side of the protruding end surface 65 to the fixing portion 61. The protruding portion 60 has corners 67 between the protruding end surface 65 and the four side surfaces 66 that are each formed by a curved surface. The protruding portion 60 also has corners 68 between the four side surfaces 66 that are each formed by a curved surface. In the perspective views of FIGS. 6(A) and 6(B), the corners 67 and 68 are curved surfaces, so no linear folds are formed. However, for convenience of illustration, the corners 67 and 68 are indicated by two-dot chain lines. The "corner" in this invention corresponds to the corner 67 in this embodiment.

[0034] As described above, in the trigger device 6 of this embodiment, the protruding portion 60 is not simply formed by bending, but is formed into a box shape by pressing, which increases the strength of the protruding portion 60 and prevents deformation when it comes into contact with the receiving portion 41 of the soft-close mechanism 4. In particular, corners 67 between the protruding end face 65 and the four side faces 66 are each curved, which prevents stress concentration at the corners 67 and further prevents deformation. Furthermore, because the corners 67 between the protruding end face 65 and the four side faces 66 are curved, they can smoothly fit into the receiving portion 41, allowing the soft-close mechanism 4 to operate smoothly.

[0035] 9 to 11, the bounce-up suppression plate 7 is a flat plate fixed facing downward to the underside of the upper plate 20 of the upper rail 2. The bounce-up suppression plate 7 is fixed above the end of the panel body 3 on the traveling direction side when the receiving portion 41 of the soft close mechanism 4 contacts the protruding portion 60 of the trigger device 6 when the sliding door 1 is opened or closed. In other words, the bounce-up suppression plate 7 is fixed above the end of the panel body 3 on the trailing side where the receiving portion 41 contacts the protruding portion 60 when the sliding door 1 is opened, and above the end of the panel body 3 on the leading side where the receiving portion 41 contacts the protruding portion 60 when the sliding door 1 is closed.

[0036] The ends of the panel body 3 on the door tail side and door front side are respectively suspended from hoisting wheels 8a and 8b running on the running portion 22 of the upper rail 2, and the bounce-up suppression plate 7 is preferably provided above the hoisting wheel 8a on the side of the panel body 3 in the direction of travel when the receiving portion 41 contacts the protrusion 60.

[0037] In this way, the bounce-up suppression plate 7 is formed on the traveling direction side of the panel body 3, which bounces up when the receiving portion 41 of the soft close mechanism 4 comes into contact with the protruding portion 60 of the trigger device 6 when the sliding door 1 is opened or closed, thereby making it possible to suppress the panel body 3 from bouncing up. In particular, when the panel body 3 bounces up, the hoisting wheels 8a, 8b come into contact with the bounce-up suppression plate 7. At this time, the hoisting wheels 8a, 8b, which are made of a relatively flexible resin, collide with the bounce-up suppression plate 7, thereby reducing vibrations and noise when they collide with the bounce-up suppression plate 7 and also suppressing malfunctions due to the collision.

[0038] The bounce-suppression plate 7 is, for example, a rectangular flat plate, but may have any shape as long as it can be stably fixed to the underside of the upper plate 20 of the upper rail 2. The bounce-suppression plate 7 may be made of metal, such as aluminum, but is preferably formed of synthetic resin foam. The bounce-suppression plate 7 is more preferably formed of rigid urethane foam. Synthetic resin foam is more likely to absorb impact when the end of the hoist wheels 8a, 8b or the soft-close mechanism 4 collides with the bounce-suppression plate 7, and rigid urethane foam in particular is highly durable. The bounce-suppression plate 7 is integrally molded. The bounce-suppression plate 7 may be formed by cutting a block of hardened rigid urethane foam into the desired shape, or by injecting raw material into a mold of the desired shape and hardening it.

[0039] The bounce-suppression plate 7 may be fixed to the upper plate 20 of the upper rail 2 with, for example, screws, but is preferably fixed by adhesive. Adhesive fixing can improve workability. Note that "adhesive fixing" here may mean adhesive fixing by applying an adhesive to the upper surface of the bounce-suppression plate 7 or the lower surface of the upper plate 20, or adhesive fixing by using double-sided tape with adhesive applied to both sides of a base material.

[0040] As mentioned above, the upper rail 2 has hanging portions 23 formed on the side plates 21 that extend downward further than the pair of running portions 22 that extend in directions approaching each other from the side plates 21, and the upper edge of the panel body 3 is inserted between the hanging portions 23, so that even when the sliding door 1 is open, the inside of the upper rail 2 is difficult to see, and the trigger device 6 and the bounce-up suppression plate 7 are not visible, improving the design. If the trigger device 6 and the bounce-up suppression plate 7 are made of black, they will be less noticeable and a decrease in design can be suppressed.

[0041] As shown in FIGS. 3 and 8 , the hoisting wheels 8a and 8b have two wheels 80, one front and one back, arranged in two rows in the width direction in the direction of movement of the panel body 3. Each wheel 80 is rotatably supported and travels on a pair of running sections 22 of the upper rail 2 when the panel body 3 moves in conjunction with the opening and closing of the sliding door 1. As shown in FIGS. 1 and 2 , the hoisting wheels 8a and 8b are formed above the upper edge 33 on both sides of the panel body 3. A connecting section 81 extending from each of the hoisting wheels 8a and 8b passes between the pair of running sections 22 and is connected to the upper edge 33 of the panel body 3, suspending the panel body 3 from the hoisting wheels 8a and 8b. One of the hoisting wheels 8a is formed so as to be continuous with the soft-close mechanism 4. The connecting section 81 is swingably connected to the hoisting wheels 8a and 8b, and the lower section of the connecting section 81 is inserted into the upper edge 33 of the panel body 3 and engaged and fixed. The support roller 10 is formed at the end opposite to the end to which the hoisting wheels 8a and 8b of the soft-close mechanism 4 are connected, and is provided with two wheels 80 in the width direction.

[0042] <About the opening and closing operation of the sliding door> Next, the opening and closing operation of the sliding door 1 will be described with reference to Figures 9 to 11. Although Figures 9 to 11 show the operation of opening the sliding door 1, the receiving portion 41 of the soft close mechanism 4, the protruding portion 60 of the trigger device 6, and the bounce-up prevention plate 7 move in the same way when the sliding door 1 is opened and closed, so the operation of closing the sliding door 1 will not be shown. In Figures 9 to 11, the direction of movement of the panel body is indicated by a white arrow with a two-dot chain line.

[0043] When the panel body 3 is slid to open or close the sliding door 1, as shown in Fig. 9, the receiving portion 41 of the soft-close mechanism 4 comes into contact with the protruding portion 60 of the trigger device 6 just before the fully closed or fully open position is reached. If the panel body 3 is slid while the receiving portion 41 and the protruding portion 60 are in contact, the receiving portion 41 swings so that the engagement notch 42 pinches the protruding portion 60, as shown in Fig. 10, and as a result, the lock of the receiving portion 41 is released. As described above, the protruding portion 60 of the trigger device 6 is box-shaped, and the corners 67 between the protruding end surface 65 and the four side surfaces 66 are each formed as curved surfaces, so that the protruding portion 60 is strong and does not easily deform. Therefore, the protruding portion 60 can be reliably caught on the receiving portion 41, and the operation of the soft-close mechanism 4 can be stabilized.

[0044] Furthermore, when the protrusion 60 and the receiving portion 41 come into contact and the soft-close mechanism 4 is activated, the speed at which the upper end of the panel body 3 slides open and closed is slowed by the soft-close mechanism 4. Then, as the lower end of the panel body 3 attempts to slide at the same speed, the panel body 3 tilts, causing the side of the panel body 3 in the direction of travel to be displaced upward (a "jump-up"). At this time, the anti-jump plate 7 is provided on the underside of the upper plate 20 of the upper rail 2, so that the hoist 8a at the upper edge 33 of the jumped-up panel body 3 collides with the anti-jump plate 7, thereby preventing further jump-up. Furthermore, if the anti-jump plate 7 is made of a synthetic resin foam such as rigid urethane foam, the vibrations and noise generated by the collision between the anti-jump plate 7 and the hoist 8a can be suppressed.

[0045] Thereafter, the receiving portion 41 of the soft-close mechanism 4 moves gently from one end to the other end of the slide hole 40 due to the action of a spring member and a braking device (not shown), as shown in Figure 11. Because the receiving portion 41 is fixed to the protruding portion 60, when the receiving portion 41 moves through the slide hole 40, the soft-close mechanism 4 other than the receiving portion 41 moves gently together with the panel body 3 to the fully closed or fully open position.

[0046] Thus, with the sliding door 1 of this embodiment, when the receiving portion 41 of the soft close mechanism 4 comes into contact with the protrusion 60 of the trigger device 6, the protrusion 60 is formed to be strong and does not deform, stabilizing the operation of the soft close mechanism 4, and the bounce-up suppression plate 7 suppresses noise and vibration caused by the panel body 3 bouncing up, allowing the sliding door 1 to be opened and closed more smoothly and stably.

[0047] It goes without saying that the embodiments of the present invention are not limited to the above-described embodiments, and can be modified as appropriate without departing from the scope of the concept of the present invention.

[0048] This specification discloses the following techniques: [Appendix 1] A sliding door comprising an upper rail that opens downward, a panel body that moves along the upper rail, a soft-close mechanism formed on the upper edge of the panel body, and a trigger device fixed to the inside of the upper rail, wherein the trigger device has a fixed part that is fixed to the upper rail and a protruding part that protrudes from the fixed part and hooks onto a receiving part of the soft-close mechanism as the panel body moves, and the protruding part is box-shaped and has a rectangular protruding end face and four side faces that connect each side of the protruding end face to the fixed part.

[0049] According to Appendix 1, the protrusion of the trigger device that hooks onto the receiving portion of the soft close mechanism is box-shaped with a rectangular protruding end face and four side faces that connect each side of the protruding end face to the fixed portion, thereby increasing the strength of the protrusion, suppressing deformation of the trigger device and preventing malfunctions when the soft close mechanism is activated.

[0050] [Appendix 2] In the sliding door of Supplementary Note 1, the protruding portion has corners formed by the protruding end surface and the four side surfaces, each of which is formed by a curved surface.

[0051] According to Supplementary Note 2, the corners of the protruding end surface and the four side surfaces are each formed with a curved surface, which makes it easier for the protruding part to fit into the receiving part of the soft-close mechanism and allows for smooth movement when the soft-close mechanism is activated. In addition, the lack of a pin angle reduces damage to the protruding part and receiving part, prevents stress concentration at the corners, and more effectively suppresses deformation of the protruding part.

[0052] [Appendix 3] In the sliding door of Supplementary Note 1, a bounce-up suppression plate is provided above the end of the panel body in the traveling direction when the receiving portion contacts the protruding portion, and extending downward from the upper rail.

[0053] According to Appendix 3, when the receiving portion and the protruding portion of the panel body collide during the opening and closing operation, a force is generated in the direction in which the panel body moves upward, but by forming a bounce-up prevention plate, the panel body can be prevented from bouncing up.

[0054] [Appendix 4] In the sliding door of Appendix 3, the upper rail is provided with a running section along which a hoisting wheel that suspends the upper edge of the panel body can run, and the bounce-up suppression plate is provided above the hoisting wheel on the side of the panel body that is in the direction of travel when the receiving section contacts the protruding section.

[0055] According to Supplementary Note 4, the bounce-prevention plate is provided above the hoist where the receiving portion and the protruding portion come into contact. Therefore, when the panel body bounces up, the hoist comes into contact with the bounce-prevention plate, thereby preventing the panel body from bouncing up. Therefore, compared to the panel body itself or the soft-close mechanism, the flexible hoist hits the bounce-prevention plate, reducing vibrations when it hits the bounce-prevention plate. Also, damage caused by the collision can be prevented.

[0056] [Appendix 5] In the sliding door of Appendix 3, the bounce-suppression plate is a synthetic resin foam.

[0057] According to Appendix 5, the bounce-up suppression plate is made of synthetic resin foam, so when the panel body bounces up, it can prevent damage to parts that collide with the bounce-up suppression plate and can suppress vibrations and noise caused by the collision.

[0058] [Appendix 6] In the fifth sliding door, the bounce-up suppression plate is adhesively fixed to the upper rail.

[0059] According to Appendix 6, the bounce-suppression plate is adhesively fixed to the upper rail, making installation easy.

[0060] [Appendix 7] In the fifth or sixth sliding door, the bounce-up suppression plate is integrally formed.

[0061] According to Supplementary Note 7, the bounce-suppression plate is integrally molded, which reduces the number of parts and simplifies the installation process.

[0062] [Appendix 8] In the sliding door of Appendix 4, the upper rail has a pair of side plates extending in the lengthwise direction and a pair of the running portions extending from the side plates in directions approaching each other, and the side plates each have a hanging portion extending downward beyond the running portion, and the upper edge of the panel body is inserted between the hanging portions.

[0063] According to Appendix 8, the pair of side panels, the pair of running sections, and the hanging section extending downward from the running sections make it difficult to see the inside of the upper rail even when the sliding door is open, so the trigger device and the bounce-up prevention plate are not visible, improving the design. [Industrial Applicability]

[0064] The sliding door according to the present invention is suitable as an indoor fixture for a house, for example. [Explanation of symbols]
