Abstract
Description
Technical Field
[0001] The present invention relates to a structure for supporting a multilayer glass or the like placed as a door material on a movable setting block for moving along a rail so that the multilayer glass or the like placed as a door material does not tilt in the front-rear direction due to plate displacement.
Background Art
[0002] In a fixed window (mortise window) in which a door material such as a plate glass is fitted into upper and lower frames at an opening of a building and fixed so as not to be opened and closed, a fixed setting block previously molded with resin or the like is disposed in the lower frame in advance to receive and buffer the load of the door material fitted into the lower frame. When a plurality of door materials are juxtaposed in the lateral direction (left-right direction) with respect to the door surface, if each door material is not horizontal but tilted left and right, a gap will occur when aligning with an adjacent door material. Therefore, in order to eliminate the tilt of the door material, the height of the fixed setting block is adjusted by sandwiching a thin resin plate on the lower side among the left and right ends while detaching and attaching the door material. Since the door material is only fixed to the upper and lower frames, it is possible to construct a highly designed one with high continuity of the door material.
[0003] In addition, in a slidable door such as a sliding door that can be opened and closed, in order to provide a door material such as a plate glass with resistance to external forces (vibrations due to wind pressure, earthquake, etc.) and to install door wheels for sliding the door material along upper and lower rails, a frame member such as a sash (sash) is attached so as to surround the peripheral edge of the door material as an outer frame. The door wheel is rotatably attached to the lower frame member and travels along the lower rail to slide the door material. However, when the door material has a left-right tilt, it is adjusted by height adjustment means or the like provided in the door wheel in advance.
[0004] When installing a sliding door in a store with a large opening such as a showroom, the dimensions and weight of the door material tend to be large, and accordingly, the found dimensions and weight of the frame material also tend to be large. There may be a desire to give the sliding door the same design quality as a fixed window. In particular, when the door material is a large plate glass, due to the requirement to ensure the visual recognition performance from the outside and the unity of the field of view, reduction of the size of the frame material is required. Without a frame material, it becomes difficult to fix the door carriage. That is, when moving the door material, if the frame material is enlarged to maintain performance such as resistance, the design quality will be sacrificed.
[0005] As described in Patent Document 1, there is also disclosed an invention of a movable setting block for slidably moving a door material along a rail by detachably placing a sashless door material made only of a large plate glass, which is arranged in the rail in advance.

Summary of the Invention
Problems to be Solved by the Invention
[0007] In the invention described in Patent Document 1, even without attaching a frame material or a door carriage to the large plate glass itself, after providing resistance to the assumed external force, it can move freely along the rail by a movable setting block. Since it is a sashless door material without a frame material, the visual recognition from the outside at the opening of a store or the like is good and the design quality is also high.
[0008] However, when using, for example, laminated glass as the door material, a space is secured between two sheets of plate glass and the ends are fixed. However, it is difficult to align two large sheets of plate glass at the same position, and some misalignment occurs. When it is tilted in the lateral direction (left - right direction) with respect to the door surface, a thin cushioning material or the like can be inserted into either the setting block arranged at the lower left or the setting block arranged at the lower right of the door material, and the height can be adjusted to make it horizontal.
[0009] However, when it is tilted in the front - rear direction with respect to the door surface, the inclination cannot be adjusted by the left - right setting blocks. When the door material is tilted in the front - rear direction, the load of the heavy door material is applied to one side of the frame of the setting block, and further, as the door material rubs against one side of the frame of the rail, the movement becomes dull and wear progresses easily. In addition, an inclination occurring between the door wheel of the setting block and the rail may cause an obstacle to running.
[0010] Therefore, an object of the present invention is to provide a movable setting block having a structure that supports a laminated glass or the like placed as a sashless door material so as not to tilt in the front - rear direction due to plate misalignment.
Means for Solving the Problems
[0011] In order to solve the above problems, the door - material support structure of the movable setting block according to the present invention includes a movable setting block arranged at the left and right ends of the lower surface of a sashless door material, with a door wheel mounted on the lower side so as to be slidable along a rail with the door material placed thereon, and an adjustment plate interposed between the door material and the movable setting block. The adjustment plate is characterized in that the door material rocks so as not to tilt in the front - rear direction with respect to the movable setting block by a raised portion whose cross - section in the front - rear direction is curved and rises downward.
[0012] In the door - material support structure of the movable setting block, the movable setting block is provided with a groove portion penetrating through the raised portion of the adjustment plate, and the raised portion is received by the frame of the door wheel.
[0013] In the door material support structure of the movable setting block, the upper surface of the adjustment plate is roughened so that the cushioning material sandwiched between the adjustment plate and the door material does not shift.
[0014] In the door material support structure of the movable setting block, the door material is a multilayer glass with a hollow between two plate glasses, and the deviation generated during the sealing of the front and rear plate glasses is absorbed by the adjustment plate.
Advantages of the Invention
[0015] According to the present invention, by interposing a member that can swing in the front-rear direction in a movable setting block for placing a sashless door material and moving it along a rail, even if there is a plate shift in the multilayer glass placed as a sashless door material, it can be supported so as not to tilt in the front-rear direction.

Embodiments for Carrying Out the Invention
[0017] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Those having the same function are denoted by the same reference numerals, and repeated explanations may be omitted.
Examples
[0018] First, the door material support structure of the movable setting block of the present invention will be described. For the door surface of the door material, the front side is the front, the back side is the rear, the direction from the front side to the back side is the front - back direction, the direction from the ceiling to the floor surface is the up - down direction (vertical direction), and the direction from the left side to the right side is the left - right direction (lateral direction). Further, the longitudinal section is the surface seen from the side after cutting vertically in the front - back direction orthogonal to the direction in which the rail extends.
[0019] FIG. 1 is a view showing an overview of a sliding door provided with a door material support structure of a movable setting block. As shown in FIG. 1, the sliding door 100 is a door that can be opened and closed by sliding a door material 300 such as glass along a rail 200 provided in an opening such as an entrance, an exit, or a window of a building or a room.
[0020] As the door material 300, for example, a thick multi-layer glass formed by combining two large glass plates is used, and a sashless type without attaching a frame material such as aluminum around it is adopted. The rail 200 is formed by making a linear groove along the passage of the door material 300 on the floor surface 110, and the lower part of the door material 300 is fitted into it.
[0021] A plurality of movable setting blocks 400 that can travel along the track are accommodated in the rail 200, and a heavy door material 300 is placed on the movable setting blocks 400 and slid. Note that the movable setting blocks 400 may be respectively arranged on the lower surfaces of the left and right ends of the door material 300.
[0022] Even for the door material 300 that is sashless and has no door wheels attached, by placing it on the movable setting blocks 400, it can be moved along the rail 200. Further, the door material 300 is only placed on the movable setting blocks 400 and is detachable.
[0023] FIG. 2 is an enlarged view of the lower right part of the sashless door material in the sliding door. FIG. 3 is a view showing a cross section in the front-rear direction of the rail in the sliding door. FIG. 4 is a view showing a situation where the inclination in the front-rear direction is adjusted by the door material support structure of the movable setting block.
[0024] As shown in FIG. 2, the movable setting block 400 that supports the lower right surface of the door material 300 can place the door material 300 on the upper part and can travel by the door wheels 500 attached to the lower part. The door wheels 500 are wheels that can rotate around an axle 520 passed through a wheel frame 510 formed by bending a metal plate into an inverted U shape.
[0025] After placing the door material 300 on the movable setting block 400, the door material 300 and the movable setting block 400 may be fastened using the end fitting 600. On the side surface of the door material 300, a side material 120 may be attached and fixed with a fastener 130 to block the gap with the adjacent door material and relieve the impact from the adjacent door material.
[0026] As shown in Fig. 3, a movable setting block 400 with a door wheel 500 mounted therein is disposed within a rail 200, and a door member 300 is placed thereon with a buffer member 140 and an adjustment plate 700 interposed therebetween.
[0027] The frame body 210 of the rail 200 has a U-shape capable of accommodating the door member 300, and the lower side from the open upper surface may be embedded in the floor surface 110. A rail base 220 on which the door wheel 500 is placed may be formed on the bottom surface of the frame body 210.
[0028] Also, sealing materials 230 are attached to the upper ends on both the left and right sides of the frame body 210. The sealing materials 230 are made of an elastic resin such as rubber, and contact the door member 300 to prevent dust and the like from entering the gap.
[0029] The movable setting block 400 is a member having an H-shaped cross section, with an upper frame 410 for placing the door member 300 and a lower frame 420 for attaching the door wheel 500. An adjustment plate 700 is placed in the upper frame 410 so as to be swingable in the front-rear direction together with the buffer member 140.
[0030] The door member 300 is, for example, a multi-layer glass. A spacer 330 is interposed between a front-side (left side in the figure) plate glass 310 and a rear-side (right side in the figure) plate glass 310 to secure a hollow layer 320, and then the ends are fixed with a sealing material 340. Since the positions of the two plate glasses 310 are adjusted manually, it is difficult to perfectly align them when they are large and heavy, and a slight deviation is likely to occur during sealing.
[0031] As shown in Fig. 4(a), when the rear-side plate glass 310 is displaced downward from the front-side plate glass 310, the door member 300 is likely to tilt toward the front side. Then, the load of the door member 300 is greatly applied to the front-side sealing material 230, making it difficult to slide due to friction, the sealing material 230 is also likely to wear, and the door wheel 500 is also likely to derail from the rail base 220.
[0032] As shown in Fig. 4(b), the adjustment plate 700 is tilted to contact both the front plate glass 310 and the rear plate glass 310, thereby suppressing the tilt of the door material 300 in the front-rear direction (left-right direction in the figure) and absorbing the displacement of the plate glass 310. The adjustment plate 700 is a plate material that can be tilted in the front-rear direction in a wasp-waist shape with the center as a fulcrum.
[0033] Fig. 5 is a perspective view of the movable setting block having a door material support structure for the movable setting block. Fig. 6 is a front view of the movable setting block. Fig. 7 is a (a) plan view and (b) bottom view of the movable setting block. Fig. 8 is a (a) left side view and (b) right side view of the movable setting block.
[0034] As shown in Fig. 5, the adjustment plate 700 is placed in the upper frame 410 of the movable setting block 400, and the end fitting 600 is attached to the end frame 450. Also, the vehicle frame 510 of the door wheel 500 is fitted into the lower frame 420.
[0035] The adjustment plate 700 forms a raised portion 720 at the center of the lower surface of the base plate 710 with a flat upper surface. The raised portion 720 has a shape in which the cross-section in the front-rear direction is curved and rises downward, and by extending in a wasp-waist shape in the direction of the rail 200, the adjustment plate 700 can swing in the front-rear direction.
[0036] On the bottom surface of the upper frame 410 of the movable setting block 400, a receiving portion 430 for placing the adjustment plate 700 is provided, and a groove portion 440 is formed at the center of the receiving portion 430 so that the raised portion 720 can enter. The groove portion 440 penetrates from the upper frame 410 side to the lower frame 420 side, and the raised portion 720 will rest on the vehicle frame 510 of the door wheel 500.
[0037] As shown in Fig. 6, a plurality of claws 460 may be provided on the lower frame 420 of the movable setting block 400 to lock the vehicle frame 510 of the door wheel 500. The vehicle frame 510 is made of metal and has the strength to receive the adjustment plate 700 on which the door material 300 is placed and the strength to ensure the rotation of the door wheel 500.
[0038] As shown in FIGS. 7(a) and 7(b), the tilt range of the adjustment plate 700 is adjusted according to the width of the groove portion 440 and the size of the raised portion 720. The tilt of the adjustment plate 700 is up to the angle at which the base plate 710 contacts the receiving portion 430. If the raised portion 720 is in contact with the lower side at a point in cross-section, it can swing in the front-rear direction. Also, the groove portion 440 may be absent or may not penetrate.
[0039] As shown in FIG. 8(a), the upper frame 410 of the movable setting block 400 has an open left side and can be fitted from the right side of the door member 300. As shown in FIG. 8(b), an insertion port 470 for attaching the end fitting 600 is also provided on the right side of the upper frame 410.
[0040] FIG. 9 is a (a) front view, (b) plan view, and (c) left side view of an end fitting used in the movable setting block. FIG. 10 is a side view of an adjustment plate used in the movable setting block.
[0041] As shown in FIG. 9, the end fitting 600 is an L-shaped member formed by bending a metal plate material, and when the door member 300 is placed on the movable setting block 400, it is fastened so that the movable setting block 400 does not come off.
[0042] The bottom plate 620 extending horizontally of the end fitting 600 is inserted into the insertion port 470 of the movable setting block 400, and the vertical plate 610 extending vertically of the end fitting 600 is applied along the side surface of the door member 300 and fastened with screws or the like.
[0043] As shown in FIG. 10, the adjustment plate 700 may be processed so that the upper surface of the base plate 710 has a rough surface 730 (for example, serrated). A cushioning material 140 is placed on the base plate 710, and a heavy door member 300 is placed thereon. When the door member 300 with a front-rear displacement is placed, the cushioning material 140 sandwiched between the door member 300 and the base plate 710 is suppressed from shifting in the direction of the tilt of the adjustment plate 700.
[0044] The buffer material 140 is, for example, a plate made of an elastic resin such as rubber, and receives the load of the door material 300. When there is a deviation in the left and right heights of the door material 300, it can be horizontally adjusted by changing the thickness of the buffer material 140 or stacking a plurality of them.
[0045] FIG. 11 is a diagram comparing the results of adjusting the inclination in the front-rear direction by the door material support structure of the movable setting block. Note that FIG. 11(a) is a photograph taken from the side without using the adjustment plate, and FIG. 11(b) is a photograph taken from the side using the adjustment plate.
[0046] As shown in FIG. 11(a), when the adjustment plate 700 is not used, the door material 300 is greatly inclined with respect to the movable setting block 400. As shown in FIG. 11(b), when the adjustment plate 700 is used, there is almost no inclination between the movable setting block 400 and the door material 300.
[0047] According to the present invention, by interposing a member that can swing in the front-rear direction in the movable setting block for placing the sashless door material and moving it along the rail, even if there is a plate shift in the multilayer glass placed as the sashless door material, it can be supported so as not to tilt in the front-rear direction.
[0048] As described above, the embodiments of the present invention have been described, but the present invention is not limited thereto. For example, not only multilayer glass but also a thick door material can be applied to suppress tilting in the front-rear direction.
