Detailed Description
Hereinafter, an embodiment of the movable partition according to the present invention will be described in detail with reference to the accompanying drawings.
(folding structure of folding door)
A panel (panel)1a used for the movable partition board 1 of [ folding door-sliding door ] shown in fig. 26 has a folding structure in which: the pair of plate bodies 1a can be folded about their central portions with the vertical direction as the axis, and can be displaced between the folded state and the expanded state. Similarly, the plate body 2a used in the movable partition 2 of [ folding door-folding door type ] shown in fig. 27 also has a folding structure in which: the pair of plate bodies 2a can be folded about their central portions with the vertical direction as an axis, and can be displaced between the folded state and the expanded state.
Fig. 1 to 18 show the folding structure of the pair of plate bodies 1a, but the folding structure of the pair of plate bodies 2a has the same structure.
Fig. 1 is a perspective view showing an upper portion of a panel body 1a in a state in the process of being folded, and shows a state in which a pair of panel bodies 1a are mounted in a folding door. Fig. 2 and 3 are exploded perspective views of the upper portion of the plate body 1 a. In a pair of plate bodies 1a constituting the folding door, the joining frames 1af are disposed to face each other. In any of the pair of plate bodies 1a, the side facing outward of the opposing portion of the joining frame 1af is referred to as the front side or front side, and the side connected to the plate body 1a is referred to as the rear side or rear side. As shown in fig. 3, the splicing frames 1af are connected by a connecting plate 10, wherein the connecting plate 10 is disposed between the splicing frames 1af and on the side which becomes the inner side in the folded state. The splice covers 11 as vertical covers are respectively fitted over the upper and lower ends of the splice frame 1af and fixed thereto. Shaft members 12 are attached to the upper and lower end portions of the connecting plate 10, respectively. Therefore, in order to secure the installation space of the shaft member 12, the linking plate 10 is formed to be shorter than the splice frame 1af, and the outer side surface of the splice frame cover 11 is formed as: the shape of the outer surface of each of the upper frame 1at and the lower frame 1ab is substantially the same as the shape of the outer surface of the upper frame 1at and the lower frame 1ab when the outer surface is attached to the joint frame 1 af. In addition, a flexible gap preventing member 13 made of rubber or the like is attached to a side surface disposed outside the splicing frame 1af in the folded state, as will be described later. Further, as shown in fig. 4, when the panel body 1a is in an expanded state in which it is not folded but expanded, it becomes: the gap preventing member 13 covers the gap formed in the opposing portion of the splice frame 1af, and the connecting plate 10 is shielded by the gap preventing member 13.
As shown in fig. 18, a pair of engaging portions 16a is attached to one surface of the splice frame 1af facing the front surface, and an engagement receiving portion 16b that engages with or disengages from the engaging portions 16a is attached to the other surface. The engaging portion 16a and the engaging receiving portion 16b constitute locking means.
The pair of engaging portions 16a are disposed at a distance that allows the engagement receiving portion 16b to be inserted between the pair of engaging portions 16 a. That is, the distance between the facing surfaces of the pair of engaging portions 16a is substantially equal to the vertical length of the engaging receiving portion 16 b. The pair of engaging portions 16a is formed as a bottomed cylindrical body, and the pair of engaging portions 16a is attached in a state where the opening sides of the cylindrical body face each other. The pair of engaging portions 16a accommodates an engaging ball 16a1, respectively, and the cylindrical body accommodates a pressing spring, not shown, and a part of the engaging ball 16a1 protrudes from the opening of the cylindrical body by a restoring force of the pressing spring.
Further, ball receiving portions 16b1 are provided on the upper and lower surfaces of the engagement receiving portion 16b, respectively, and the ball receiving portion 16b1 can receive a part of the engagement ball 16a1 protruding from the opening of the engagement portion 16 a.
In the present embodiment, the description has been given taking the example in which the pair of engaging portions 16a is provided, but only one of the engaging portions 16a may be provided. In order to more reliably exhibit the function described later, it is preferable to provide a pair of engaging portions 16 a. In addition, with respect to the engaging portion 16a and the engagement receiving portion 16b, it is preferable that: an appropriate number of groups are set according to the length of the splice frame 1af, etc.
As shown in fig. 26, the vertically intermediate portion of the plate body 1a is held by the two bars 1an, 1am, i.e., the upper bar 1an and the lower bar 1 am. The engaging portion 16a and the engaging receiving portion 16b are attached to the splicing frame 1af by screws for fixing the upper bar 1an at a position not easily touched among the bars 1an and 1 am. When the engaging portion 16a and the engaging receiving portion 16b are attached to the positions corresponding to the lower bar 1am, since the height of the lower bar 1am is at a position where the operation of displacing the plate body 1a between the folded state and the expanded state is easy, there is a possibility that fingers may be caught on the plate body during the operation, and therefore, it is preferable that the engaging portion 16a and the engaging receiving portion 16b are not attached to the positions corresponding to the lower bar 1 am.
Depending on the situation, the upper side bar 1an may not be connected, but may be directly attached to the splice frame 1 af.
In addition, similarly, the plate body 2a of the movable partition 2 is preferably: the engaging portions 16a and the engaging receiving portions 16b are attached corresponding to the upper bars 2 an. In addition, similarly to the case of the movable partition 1, it is not preferable from the viewpoint of the height position if the engaging portion 16a and the engaging receiving portion 16b are associated with the lower bar 2 am.
Fig. 5 to 8 are perspective views showing the relationship between the linking plate 10, the splice cover 11, and the shaft member 12, in which fig. 5 and 6 are perspective views seen from above, and fig. 7 and 8 are perspective views seen from below. Fig. 9 is a cross-sectional view showing the web 10 and the splice frame 1af separated from each other.
As shown in fig. 9, the linking plate 10 is formed to have a substantially symmetrical cross section, and a pair of holding tongues 10b and a pair of receiving tongues 10d are provided on the main body plate 10 a. The outer surface of the main body plate 10a is formed to be substantially flat. Inside the main body plate 10a, there are provided: a holding tongue piece 10b protruding inward from the side end and having a tip bent toward the center side, and a holding portion 10c formed in the bent inner portion of the holding tongue piece 10 b. A pair of receiving tongues 10d projecting inward are provided at an appropriate interval in the center portion of the inner side of the linking plate 10. The receiving tongue pieces 10d are formed such that the tip ends thereof extend toward the side surfaces, the interval between the pair of receiving tongue pieces 10d gradually increases toward the tip end side, and a substantially V-shaped space portion formed between the surfaces on the center side of the receiving tongue pieces 10d serves as a shaft member receiving portion 10 e.
The side surface of the receiving tongue piece 10d is formed as a curved surface, and the clamping portion 10c is formed by the side surface formed by the curved surface and the curved inner surface of the clamping tongue piece 10 b. Further, the side-surface-side curved surface of the receiving tongue 10d and the curved inner surface of the pinching tongue 10b are connected to each other to form a spiral shape, whereby the pinching portion 10c can be formed into a spiral shape having a hollow cross section. The throat 10f of the clamping portion 10c is formed by appropriately separating the tip of the receiving tongue 10d and the tip of the clamping tongue 10 b.
On the other hand, a clamped portion 10g connected to and clamped by the clamping portion 10c is provided at the end portion of the front wall portion of the splice frame 1af that is on the inner side when folded. The clamped portion 10g has a neck portion 10g1 protruding forward from the front surface of the splice frame 1af, and a clamping end 10h formed by winding the tip end of the clamped portion 10g in a state clamped by the clamping portion 10 c. In addition, as described above, when the clamp 10c is formed in a spiral shape having a hollow cross section, the clamped portion 10g is formed in a solid spiral shape accommodated in the hollow spiral shape of the clamp 10c, whereby the clamp 10c and the clamped portion 10g can be reliably connected.
The neck 10g1 of the clamped portion 10g passes through the throat 10 f. Further, a locking projection 10g2 is provided on the side surface of the neck portion 10g1 opposite to the side surface enclosed by the pinched portion 10 c. As shown in fig. 14, the locking projection 10g2 abuts on the tip of the receiving tongue piece 10d of the connecting plate 10, whereby the position of the clamped portion 10g relative to the clamping portion 10c is regulated, and the plate body 1a is brought into an expanded state.
Further, by providing an appropriate gap between the hollow spiral-shaped sandwiching portion 10c and the solid spiral-shaped sandwiched portion 10g, as will be described later, when the joining frame 1af is swung with respect to the connecting plate 10 with the shaft portion 12b of the shaft member 12 as an axis, the sandwiched portion 10g can be smoothly moved with respect to the sandwiching portion 10 c.
When the splice frame 1af and the web 10 are connected, the end of the web 10 is inserted from the end of the splice frame 1af, and the web 10 is slid in the longitudinal direction of the splice frame 1 af. At this time, the insertion is performed such that the clamping end 10h is clamped by the clamping portion 10c of the connecting plate 10.
Thus, the connecting plate 10 and the pair of joining frames 1af are integrated, and when the joining frames 1af are rotated as described later, the clamping end 10h is moved in the clamping portion 10c while maintaining the state in which the clamping end 10h is clamped by the clamping portion 10 c.
As shown in fig. 5 to 8 and 10, the shaft member 12 is connected to the linking plate 10 and the splice cover 11. The connection between the linking plate 10 and the shaft member 12 will be described with reference to fig. 6 and 8.
Although the splice cover 11 and the shaft member 12 are disposed above and below the splice frame 1af, respectively, fig. 5 to 8 show the splice cover 11 and the shaft member 12 disposed above. Therefore, the term "up and down" in the following description relates to the shaft member 12 or the splice cover 11 disposed on the upper portion.
As shown in fig. 6, 8, and 10, the shaft member 12 is mainly configured by a base portion 12a formed in an elliptical shape. Two shaft portions 12b projecting upward are provided on the top surface of the base portion 12 a. As shown in fig. 10, the shaft member 12 is provided on the bottom surface thereof with a web receiving portion 12c projecting downward from one of the long sides of the oval shape of the base portion 12 a. The web receiving portion 12c includes: a flat plate portion 12c1 extending along one long side of the oval shape, and a protruding portion 12c2 protruding from the central portion of the flat plate portion 12c1 toward the other long side of the oval shape. The bottom surfaces of the flat plate portion 12c1 and the protruding portion 12c2 are formed as flat surfaces, and become the link receiving surface 12c 3. That is, in a state where the shaft member 12 is connected to the web 10, the end surface of the web 10 abuts on the web receiving surface 12c 3.
A connecting portion 12d is provided at a central portion of the connecting plate receiving surface 12c3, the connecting portion 12d is formed in a shape conforming to the shaft member receiving portion 10e of the connecting plate 10, and the connecting portion 12d is inserted into the shaft member receiving portion 10e and has a substantially V-shaped cross section. As shown in fig. 5, 6, and 9, the shaft member receiving portion 10e of the connecting plate 10 is formed in a shape that the receiving tongue 10d side is expanded in cross section, the connecting portion 12d is formed in a shape that the flat plate portion 12c1 side, which is the distal end side, is narrowed, and the distal end portion of the flat plate portion 12c1 side is inserted into the main plate 10 side of the shaft member receiving portion 10e of the connecting plate 10. A holding plate 12e is provided at an end portion of the connection portion 12d on the side having a relatively thick cross-sectional shape on the proximal end side. The outer surface of the receiving tongue 10d of the connecting plate 10 abuts on the surface of the holding plate 12e on the side of the connecting portion 12 d. In a state where the web 10 and the shaft member 12 are connected, the connecting portion 12d is inserted into the shaft member receiving portion 10e of the web 10, and the front end surface of the web 10 abuts on the web receiving surface 12c3 as described above.
The splice frame cover 11 is formed in a square box shape, and the outer shape of the side plate thereof is formed in a shape substantially matching the outer shape of the splice frame 1 af. Fig. 5 to 8 show a state in which the splice covers 11 attached to the splice frames 1af of the pair of plate bodies 1a are connected to each other.
The upper surface of the splice bezel 11 substantially coincides with the upper surface of the upper frame 1at in the state attached to the splice frame 1 af. Further, a gap preventing member mounting groove 11a to which a gap preventing member described later is mounted is provided on the top surface of the splice frame cover 11. The lower surface side of the splice bezel 11 is a space portion of the rectangular box, and as shown in fig. 7 and 8, a rib (rib) for ensuring strength is appropriately disposed in the space portion. Further, a shaft hole 11b into which the shaft portion 12b of the shaft member 12 is individually inserted is provided on the lower side of the splice cover 11.
Fig. 13 shows a splice cover 111 having a shape different from that of the splice cover 11 described above. The splice covers 111 covering the splice frame 1af each have a tooth 111c similar to the tooth 11c of the splice cover 11. Fig. 13 is a plan view partially omitted showing a state where these tooth portions 111C are engaged with each other, in which (a) shows a state where the pair of plate bodies 1a are in the folded state, (B) and (C) show states in which the pair of plate bodies 1a are shifted from the folded state to the expanded state in this order, and (D) shows a state where the pair of plate bodies 1a are in the expanded state.
As shown in fig. 11, in the above-described split bezel 11, when the plate body 1a is in the expanded state, the side where the tooth portion 11c is not formed is formed as: the front faces are in close contact with each other, or the end portions are slightly spaced. Therefore, there is a possibility that the tip of a finger or toe is caught between the splice covers 11, and particularly, there is a possibility that the tip of a toe is caught between the splice covers 11 on the lower side.
In contrast, in the spliced bezel 111 shown in fig. 13, the fingertip or toe tip can be prevented from being inadvertently caught.
On the surface on the front surface side of the split bezel 111, and on one end side, a tooth portion 111c is formed, and on the portion on the other end side where the tooth portion 111c is not formed, as shown in fig. 13 (D), from the end portion to an appropriate position of the central portion: and outer flat surfaces 111a which are substantially parallel to each other in the expanded state of the plate body 1 a. A space formed by the gap between the outer flat surfaces 111a forms a pinch-preventing gap Ga. On the other hand, an inner flat surface 111b is formed at an appropriate position from the root of the tooth 111c and the root of the center portion of the front surface of the splice frame cover 111. As shown in fig. 13 (D), when the plate body 1a is in the expanded state, the inner side flat surfaces 111b abut against each other.
The inclined surface 111d, which is a plane in the direction intersecting the outer flat surface 111a and the inner flat surface 111b, connects the end of the outer flat surface 111a on the central side and the end of the inner flat surface 111b on the central side. That is, the inclined surface 111d is formed as follows: the outer flat surface 111a is widened from the end of the inner flat surface 111b toward the end of the outer flat surface 111 a. In addition, a space portion is also formed between the inclined surfaces 111d at an appropriate interval, and the space portion also constitutes a part of the sandwiching prevention gap Ga.
Further, the following may be configured: the width is increased from the end of the inner flat surface 111b on the central side to the end of the outer flat surface 111a on the central side without providing the inclined surface 111d, thereby forming the sandwiching prevention gap Ga.
Therefore, as shown in fig. 13 (B), in the process of rotating the plate body 1a to the expanded state with the fingertip F positioned between the splice covers 111, the fingertip F contacts the inclined surface 111d, and at this time, the fingertip F is pushed out by the force in the direction narrowing between the inclined surfaces 111d, and the user feels the risk of pinching the fingertip F and avoids the fingertip F quickly. Even if the rotation of the plate body 1a is continued to be in the expanded state, the fingertip F is not pinched by appropriately enlarging the distance between the outer flat surfaces 111a of the pinching prevention gap Ga from the fingertip F.
As shown in the cross-sectional views of fig. 14 and 15, the finger operation portion 1af1 formed by projecting the side wall rearward is formed on the side end portion on the back side of the splice frame 1 af. As shown in fig. 19, a front side finger operation portion 1ap1 formed by bulging toward the side is formed on the front side end of the vertical frame 1 ap. Further, a rear side finger operation portion 1ap2 is provided on the rear side end of the vertical frame 1ap so as to project laterally.
(deflection motion of folding door)
The displacement operation of the folding door between the folded state and the extended state will be described with reference to fig. 11 to 18.
Fig. 11 and 14 are views showing a pair of plate bodies 1a of the sliding type movable partition 1 of the folding door-sliding door type in an expanded state. Fig. 16 and 17 show the operation of the splice frame 1af swinging with respect to the connecting plate 10 in the process of displacing the pair of plate bodies 1a from the expanded state to the collapsed state. That is, fig. 16 (a) shows the expanded state, and then the expanded state is gradually swung to change to the folded state shown in fig. 17 (C).
In the expanded state shown in fig. 11, 14, and 16 (a), the two plate bodies 1a are arranged in the same straight line and are formed in a single plate shape, and can function as a sliding door. Fig. 11 is a plan view of the two plate bodies 1a, and fig. 14 is a cross-sectional view of the splice frame 1af of the two plate bodies 1 a. Fig. 16 and 17 are cross-sectional views of the splice frame 1 af. Since the pair of panels 2a of the folding door/folding door type movable partition 2 has the same structure as the panel 1a, only the panel 1a will be described. In the case of the movable partition 2, the plate body 2a does not function as a sliding door.
As for the splice covers 11, 111 covering the splice frames 1af of the two plate bodies 1a, as shown in fig. 11 and 13, the tooth portions 11c formed on the splice covers 11 are engaged with each other, and the tooth portions 111c formed on the splice covers 111 are engaged with each other. The following description is made of the splice cover 11. In addition, as described above, the splice cover 111 includes: a function of preventing the finger tip F from being pinched when the finger tip F is displaced from the folded state to the expanded state.
When the two plate bodies 1a are in the expanded state, as shown in fig. 14 and fig. 16 (a), the outer side surface of the main body plate 10a of the linking plate 10 and the side surface of the splice frame 1af are located in the same plane. In addition, at: the gap formed between the splicing frames 1af is blocked by the gap preventing member 13 provided at the end opposite to the side connected to the connecting plate 10. As shown in fig. 14, 16, and 17, it is preferable that: the gap preventing member 13 attached to one of the opposing split frames 1af and the gap preventing member 13 attached to the other split frame are turned over and combined, and a space 13b is formed in a portion between the tongue pieces 13a of the gap preventing member 13.
Fig. 12, 15, 16 (B), 16 (C), 17 (a), and 17 (B) show a state in which the two plate members 1a are displaced between the folded state and the expanded state, and the two plate members 1a are further folded from this state to form a state in which the two plate members 1a are parallel to each other, thereby forming the folded state shown in fig. 17 (C).
When the two plate bodies 1a in the expanded state are displaced to the collapsed state, as shown in fig. 11, 14, and 16 (a), the splicing frame 1af is moved in the direction indicated by the arrow P. At this time, when the operation is performed from the link plate 10 side, the splice frame 1af is pushed in the direction indicated by the arrow P. When the user operates the gap preventing member 13, the finger tip hooks the finger operating part 1af1 and pulls the finger toward the user, thereby moving the splice frame 1af in the direction of the arrow P.
When the joint frame 1af moves in the direction of the arrow P, the two plate bodies 1a swing around the connecting portion between the upper frame 1at and the upper rail 1b, which will be described later. By this swing, the splice frame 1af moves laterally toward the upper rail 1b, and moves so that the connection portion between the upper frame 1at of the two plate bodies 1a and the upper rail 1b approaches. When the joint frames 1af move in the arrow P direction, each joint frame 1af swings about the shaft portion 12b of the shaft member 12.
When the splice frame 1af is swung about the shaft portion 12b of the shaft member 12 as shown in fig. 16 and 17 in order to be displaced from the expanded state to the collapsed state, the clamped portion 10g of the splice frame 1af moves within the clamping portion 10c of the link plate 10.
In the expanded state, as shown in fig. 16 (a), the clamped portion 10g is positioned at the innermost side of the clamping portion 10c, and the locking projection 10g2 of the clamped portion 10g is in contact with the tip of the receiving tongue 10d of the connecting plate 10.
When the clamp 10g is displaced from the expanded state to the folded state, the clamp 10c moves gradually. Since the joining frame 1af on which the clamped portion 10g is disposed swings about the shaft portion 12b of the shaft member 12, the clamped portion 10g must be allowed to move relative to the clamping portion 10c in order to allow the joining frame 1af to swing relative to the connecting plate 10. As described above, when the clamping portion 10c is formed in a hollow spiral shape and the clamped portion 10g is formed in a solid spiral shape connected to the clamping portion 10c, the gap is formed between the clamping portion 10c and the clamped portion 10g, thereby allowing the clamped portion 10g to move relative to the clamping portion 10c and the splicing frame 1af to swing relative to the connecting plate 10.
When the clamped part 10g moves relative to the clamping part 10c, the clamped part 10g moves in a direction gradually separating from the clamping part 10 c. The moving direction of the clamped portion 10g is a direction in which the locking projection 10g2 of the clamped portion 10g separates from the tip of the receiving tongue piece 10 d. When the folded state is shown in fig. 17 (C), the clamped portion 10g is separated to the position where it protrudes most from the clamping portion 10C. Even in this state, the splice frame 1af and the connecting plate 10 are connected so that the clamped portion 10g does not completely separate from the clamping portion 10 c. Therefore, when the splice frame 1af and the link plate 10 are connected, as described above, the end of the link plate 10 is inserted from the end of the splice frame 1af so that the clamping end 10h is clamped by the clamping portion 10c of the link plate 10, and the link plate 10 is slid in the longitudinal direction of the splice frame 1 af.
At this time, the teeth 11c formed on the pair of split covers 11 are rotated about the shaft 12b, and the meshed state is maintained, so that the pair of split covers 11 are rotated in synchronization.
When the two plate bodies 1a in the folded state are displaced to the expanded state, the vertical frame 1ap of one plate body 1a is moved in a direction separating from the vertical frame 1ap of the other plate body 1 a. Thus, the splice cover 11 swings about the shaft portion 12b of the shaft member 12, and the two plate bodies 1a are rotated in synchronization by the meshing relationship of the tooth portions 11c, so that the two plate bodies 1a are expanded. At this time, the clamped portion 10g moves in the clamping portion 10c, and when the clamped portion is in the expanded state as shown in fig. 14, the locking projection 10g2 abuts on the tip of the receiving tongue piece 10d of the connecting plate 10.
When the extended state is shifted, the engagement receiving portion 16b is moved to a position between the pair of engagement portions 16a shown in fig. 18, and the engagement portion 16a and the engagement receiving portion 16b are engaged with each other. When the engagement balls 16a1 partially protruding from the engagement portion 16a pass through the edge portions of the upper and lower surfaces of the engagement receiving portion 16b, the engagement balls 16a1 are buried in the cylinder of the engagement portion 16a against the restoring force of a pressing spring (not shown), and pass over (contact and pass over) the upper and lower surfaces of the engagement receiving portion 16 b. When the engaging ball 16a1 reaches the ball receiving portion 16b1 of the engaging receiving portion 16b, the engaging ball 16a1 is received in the ball receiving portion 16b1 by the restoring force of the pressing spring, and the engaging portion 16a and the engaging receiving portion 16b are engaged with each other. When the engaging portion 16a and the engaging receiving portion 16b are engaged with each other, the splicing frames 1af are locked to each other, and the expanded state is maintained.
When the two plate bodies 1a in the expanded state are displaced to the collapsed state, the splice frame 1af is rotated by the force in the direction indicated by the arrow P in fig. 11, 14, and 16 (a), as described above. By this rotation, the engagement between the engagement ball 16a1 and the ball receiving portion 16b1 is released, and the plate body 1a can be folded. The engagement between the engagement ball 16a1 and the ball receiving portion 16b1 is released by the engagement ball 16a1 being disengaged from the ball receiving portion 16b1 by the rotation of the joint frame 1 af. At this time, the engagement ball 16a1 is buried in the cylinder of the engagement portion 16a against the restoring force of the not-shown pressing spring, and the engagement between the engagement portion 16a and the engagement receiving portion 16b can be released. When the engaging balls 16a1 are disengaged from the upper and lower surfaces of the engaging receiving portion 16b, the engaging balls 16a1 are in a state of protruding from the engaging portion 16a by the restoring force of the pressing spring.
In addition, the two plate bodies 1a in the expanded state can function as a slide door, and at this time, the plate body 1a can be moved along the upper guide rail 1B and the lower guide rail 1C by grasping the front side finger operation part 1ap1 formed on the vertical frame 1ap with a finger as shown in fig. 19 (B) or by hooking the rear side finger operation part 1ap2 with a finger tip as shown in fig. 19 (C).
As described above, in the folding structure of the folding door, the splice frame 1af of the two panel bodies 1a is connected by the connecting plate 10, and the splice frame 1af of each panel body 1a is swung with respect to the connecting plate 10, whereby the folding structure can be freely displaced between the folded state and the extended state. The connecting plate 10 is integrally connected to the splice frame 1af in the vertical direction of the splice frame 1af, and therefore, a gap is not formed in the vertically intermediate portion of the splice frame 1 af.
The swinging of the plate body 1a is performed as the splice bezel 11 disposed on the splice frame 1af is rotated about the shaft portion 12b of the shaft member 12. That is, the joining frame 1af can be swung by the connecting plate 10, the joining frame cover 11, and the shaft member 12, so that the structure can be further simplified, the number of components can be reduced, and the swinging of the pair of joining frames 1af can be easily synchronized.
Even if the splice frame 1af swings with respect to the connecting plate 10, the clamped portion 10g does not fall off from the clamping portion 10 c.
Further, when the two plate bodies 1a are in the expanded state, the outer side surface of the main body plate 10a of the connecting plate 10 and the side surface of the splice frame 1af can be in the same plane, and therefore, when in the expanded state, there is no portion protruding outward, and the appearance is not impaired.
In addition, when the pair of plate bodies 1a is in the expanded state, the joint frames 1af of the two plate bodies 1a are opposed to each other in the front side, and a gap is formed between these joint frames. When the folded state is shifted to the expanded state, the gap preventing member 13 is provided, and therefore, fingers and the like can be prevented from being caught in the gap. Also, in the expanded state, the gap is shielded by the gap preventing member 13, and therefore, the gap does not appear on the appearance of the movable partition 1, and the appearance of the movable partition 1 is not affected.
Further, by using a flexible material such as rubber for the gap preventing member 13, even if a finger hits the gap preventing member 13, the finger is appropriately bent, and thus no impact is given. The gap preventing member 13 is preferably formed as a hollow body to reduce the weight.
When the plate body is in the expanded state, the room is divided into two rooms to be used, and therefore, it is not preferable to fold the plate body carelessly. Therefore, in order to maintain the expanded state, locking means composed of the engaging portion 16a and the engaging receiving portion 16b for locking the splice frames to each other is provided. The locking means is preferably formed so as to be freely engageable with and disengageable from each other, and is capable of releasing the engagement with an appropriate force to fold the panel.
Further, by providing the finger operation section 1af1, the front side finger operation section 1ap1, and the back side finger operation section 1ap2 on the joint frame 1af or the vertical frame 1ap of the plate body 1a, the folding door of the movable partition board 1 can be displaced without any trouble or moved as a sliding door.
On the other hand, as shown in fig. 26, 28 and 29, the handle 1ah, the handle 3ah and the handle 4ah are generally provided on the vertical frame 1ap or the like, whereby the plate body 1a of the movable partition board 1 is operated. In the present embodiment, the plate body 1a of the movable partition board 1 is operated without providing such a handle 1ah or the like, but for example, it is preferable that: the handle 1ah and the like are attached according to the user's request.
In addition, when the handle or the like is not attached, the plate body can be miniaturized, and the movable partition can be miniaturized.
(supporting structure of plate body and connecting structure between upper frame, lower frame and guide rail)
When the plate body 1a having a small thickness is used, the plate body 1a may be bent when a force is applied to the surface of the plate body 1a as indicated by an arrow S in fig. 20 (B). In particular, when the movable floor 1 is to be miniaturized for installation in a general housing, the upper frame 1at, the lower frame 1ab, the joining frame 1af, and the vertical frame 1ap are miniaturized, and the plate body 1a having a small thickness is used. Therefore, it is possible to cause the plate body 1a to be bent with a small force. Therefore, the following structure is required: when the plate body 1a is to be bent, the bending is allowed and the structure can be restored to the original state.
Fig. 20 to 22 are vertical sectional views showing the structure of the connection portion between the plate body 1a, the upper frame 1at, and the upper side rail 1b, and the connection portion between the plate body 1a, the lower frame 1ab, and the lower side rail 1 c.
The plate body 1a is held by upper and lower ends of the plate body 1a being supported by a lower side wall of the upper frame 1at and an upper side wall of the lower frame 1ab, respectively.
As shown in fig. 21, a support groove 1at1 is formed in the lower side wall of the upper frame 1at along the longitudinal direction of the upper frame 1at, and the upper end of the plate body 1a is inserted into the support groove 1at 1. Further, a cushion member 1ad having appropriate elasticity is disposed in the support groove 1at1, and the end of the plate body 1a and the support groove 1at1 are connected via the cushion member 1 ad. Therefore, the plate body 1a is allowed to be appropriately inclined with respect to the upper frame 1 at.
The upper frame 1at is provided with an upper shaft 1at2 having an axial direction in the vertical direction, and an upper end of the upper shaft 1at2 protrudes above the upper frame 1 at. On the other hand, a pair of rollers (rollers) 1b1 which can freely roll in the longitudinal direction are disposed on the upper rail 1 b. The roller 1b1 is supported as follows: the support shaft 1b3 supported by the support block 1b2 is rotatable about the support shaft, and the rotation causes the upper rail 1b to roll under the guidance of the upper rail. The roller 1b1 has a support shaft 1b3 oriented perpendicular to the axial direction of the upper shaft 1at2, and the upper end of the upper shaft 1at2 is rotatably supported by a support block 1b 2. The plate body 1a is displaced between the folded state and the expanded state by the rotation of the upper shaft 1at2 with respect to the support block 1b 2. Further, a flange portion 1at21 is formed at the upper portion of the upper shaft 1at2, and a gap Gt is formed between the flange portion 1at21 and the bottom surface of the support block 1b2, whereby the upper shaft 1at2 is allowed to be inclined at an appropriate angle with respect to the direction perpendicular to the rotation axis of the roller 1b 1.
Further, a pair of gap preventing members 14 are provided at the side end portion of the top surface of the upper frame 1at so as to sandwich the upper shaft 1at2, and the gap formed between the upper frame 1at and the upper rail 1b is blocked by bringing the tip ends of the gap preventing members 14 close to the upper rail 1 b. The gap preventing member is formed of a material such as rubber, and has flexibility.
As shown in fig. 22, a support groove 1ab1 is formed in the upper side wall of the lower frame 1ab along the longitudinal direction of the lower frame 1ab, and the lower end of the plate body 1a is inserted into the support groove 1ab 1. Further, a cushion member 1ae having appropriate elasticity is disposed in the support groove 1ab1, and the end of the plate body 1a and the support groove 1ab1 are connected via the cushion member 1 ae. Thus, the plate body 1a is allowed to be appropriately inclined with respect to the lower frame 1 ab.
The lower frame 1ab accommodates a spring housing 1abb formed in a bottomed cylindrical shape, and the spring housing 1abb accommodates a pressing spring 1ab2 made of a compression coil spring. The spring housing 1abb is configured to: the pressing spring 1ab2 is appropriately held and housed by the bottom portion, which is the upper portion of the spring frame 1abb, with the bottom portion thereof being above and the opening 1abb1 being below. The spring housing 1abb accommodates a lower shaft 1ab3, and the tip of the lower shaft 1ab3 protrudes from the opening 1abb 1. The lower shaft 1ab3 is slidable in the axial direction relative to the spring housing 1 abb. A pressing spring 1ab2 is connected to a proximal end portion of the lower shaft 1ab3 so as to be engageable with and disengageable from each other, and when the pressing spring 1ab2 is engaged, a restoring force of the pressing spring 1ab3 acts in a direction in which the lower shaft 1ab3 protrudes from the spring frame 1 abb.
Further, the following may be configured: the spring housing 1abb and the lower shaft 1ab3 constitute a so-called telescopic shaft which is telescopic, and the outer cylinder thereof is provided with a pressing spring 1ab 2.
A slider 1d connected to the lower rail 1c is connected to the tip of the lower shaft 1ab3, and the slider 1d is connected to the lower shaft 1ab3 and the slider 1d with an appropriate clearance as an appropriate clearance, and is supported so as to be rotatable about the shaft of the lower shaft 1ab 3. Further, the slider 1d is pressed against the lower rail 1c by the restoring force of the pressing spring 1ab 2. A guide rail portion 1c1 having a dovetail cross-sectional shape is provided on the top surface of the lower guide rail 1c, and a dovetail guide rail groove portion 1d1 for accommodating the guide rail portion 1c1 is formed in the lower portion of the slider 1 d. In a state where the rail portion 1c1 is accommodated in the rail groove portion 1d1, an appropriate gap Gb is provided between the inner surface of the rail portion 1c1 and the outer surface of the rail groove portion 1d 1.
Further, the connection portion between the lower shaft 1ab3 and the slider 1d is formed in a shape having a reduced diameter, and a gap Gs is provided between the end portion on the diameter expansion side of the lower shaft 1ab3 and the slider 1 d. Therefore, the inclination of the lower shaft 1ab3 with respect to the slider 1d and the inclination of the slider 1d with respect to the lower rail 1c are permitted by these gaps Gb and Gs.
Further, a pair of gap preventing members 15 are provided on the side end portion of the bottom surface of the lower frame 1ab so as to sandwich the lower shaft 1ab3, and the gap formed between the lower frame 1ab and the lower rail 1c is shielded by bringing the front ends of the gap preventing members 15 close to the lower rail 1 c. In addition, the gap preventing member is formed of a material such as rubber, and has flexibility.
The upper shaft 1at2 and the lower shaft 1ab3 described above are coaxially arranged. In addition, in the two plate bodies 1a of the movable partition board 1 of the folding door-sliding door type, a connection portion including the upper shaft 1at2 and the lower shaft 1ab3 is disposed at one position of the upper frame 1at and the lower frame 1 ab. The respective connecting portions of the two plate bodies 1a are provided at positions that are axisymmetrical with respect to the connecting plate 10.
In the two plate bodies 2a of the sliding type bulkhead 2 of the folding door-folding door type, similarly, the upper shaft 1at2 and the lower shaft 1ab3 are disposed at one position of the upper frame 2at and the lower frame 2 ab.
The upper shaft 1at2 is rotatable with respect to the support block 1b2, and the lower shaft 1ab3 is rotatable with respect to the slider 1 d. Therefore, the upper shaft 1at2 is rotatable with respect to the upper rail 1b accommodating the support block 1b2, and the lower shaft 1ab3 is rotatable with respect to the lower rail 1c engaging with the slider 1 d. Therefore, in the case of the folding door, when the plate body 1a is rotated to be displaced between the folded state and the expanded state, the plate body can be rotated about the upper shaft 1at2 and the lower shaft 1ab3, respectively.
In the case of the movable partition 3 and the movable partition 4 that function only as sliding doors and do not function as folding doors, and the plate body 3a, the plate body 4a, and the plate body 5a used for the movable partition 5, it is preferable that: the upper shaft 1at2 and the lower shaft 1ab3 are provided at a plurality of positions.
Further, since the gap preventing member 14 and the gap preventing member 15 are attached, it is possible to prevent fingers from being inserted into the gap between the upper frame 1at and the upper side rail 1b or the gap between the lower frame 1ab and the lower side rail 1 c. In particular, since there is a possibility that the toe tip may be inserted into the gap between the lower frame 1ab and the lower rail 1c, it is preferable that: the gap prevention member 15 is provided at least on the lower frame 1 ab. Further, it is also preferable that: the interval between the lower frame 1ab and the lower rail 1c is formed to a size such that toes are not inserted.
Further, by forming the gap preventing members 14 and 15 of rubber or the like and having flexibility, the fingers can be appropriately bent even when they are touched, and thus no impact is given.
(shaking prevention structure of trackless sliding door)
In the movable partitioning plate 4 of the trackless sliding door type, the lower rail is not laid, but the upper frame 4at is suspended and supported by the upper rail 4b, and the lower frame 4ab is in a free state. Therefore, when a force is applied from the side of the plate body 4a or the like, the plate body 4a may swing left and right about the connection portion between the upper frame 4at and the upper rail 4 b. When the plate body 4a swings, there is a possibility that the function of the movable partition 4 is affected, and therefore, it is preferable to prevent the swing.
Therefore, the movable partition 4 of the trackless sliding door type preferably has a swing prevention function. Hereinafter, a sway preventing structure for realizing the sway preventing function will be described.
Fig. 23 is a perspective view of the floor guide 40, and fig. 24 is a perspective view of the plate body guide 42. A pair of gap preventing members 15 are attached to the lower frame 4ab of the plate body 4 a.
As shown in fig. 23, the floor guide 40 includes a support plate portion 40a fixed to the floor surface and an engagement portion 40b projecting upward from one end portion of the support plate portion 40 a. The support plate portion 40a is provided with a through hole 40a1 through which a fixing bolt or the like is inserted when fixed to the floor surface. A cushion holding portion 40b1 whose width is reduced relative to the lower portion is formed at the upper portion of the locking portion 40b, and as shown in fig. 25, a cushion 40c formed in a cylindrical shape is held by the cushion holding portion 40b 1.
The plate body guide 42 is formed of a strip plate material into a substantially U-shape, and one arm portion of the U-shape is more elongated than the other arm portion. The arm portion on the extension side becomes the support arm portion 42a, and the arm portion on the shorter side becomes the locking arm portion 42 b. The support arm portion 42a is fixed to a side surface of the vertical frame 4ap which is a splice portion of one panel 4a where the sliding doors overlap each other, and the locking arm portion 42b is engaged with the other panel 4 a. The support arm portion 42a is provided with a through hole 42a1 through which a fixing bolt or the like is inserted when fixed to the plate body 4 a. The buffer holding portion 42b1, which is formed to have a smaller width than the lower portion, is formed at the upper portion of the locking arm portion 42b, and as shown in fig. 25, the buffer 42c formed in a cylindrical shape is held by the buffer holding portion 42b 1.
For example, in the movable partition 4 of the trackless sliding door type constituted by two plate bodies 4a, the two plate bodies 4a are suspended and supported on different upper guide rails 4b, and the respective moving trajectories thereof are different. Therefore, the two plate bodies 4a can be overlapped with each other over the entire area, and when the two plate bodies 4a are divided into two rooms as partitions, the vertical frames 4ap of the two plate bodies 4a are overlapped at the joint portion.
Fig. 25 is a vertical cross-sectional view showing a joint portion when divided into two rooms, in which a floor guide 40 is fixed to a floor surface of a portion where a vertical frame 4ap of one plate body 4a is located. When the support plate portion 40a of the floor guide 40 is fixed to the floor surface, the engagement portion 40b is in a state of rising upward. In this state, the cushion holding portion 40b1 is located between the pair of gap preventing members 15 attached to the lower frame 4ab of the plate body 4a that moves while passing above the floor guide 40. Further, as shown in fig. 25, it is preferable that: a recess 4ab1 extending in the longitudinal direction is formed in the bottom surfaces of the lower frame 4ab and the vertical frame cover 4ap1, and the buffer 40c is inserted into this recess 40ab 1.
The plate body 4a passing above the floor guide 40 moves in a state where the cushion holding portion 40b1 is connected to the gap preventing member 15 or the recess 4ab 1. Therefore, when the plate body 4a passing above the floor guide 40 attempts to swing, the cushion 40c of the cushion holding portion 40b1 abuts against the play prevention member 15 or the recess 4ab1 to prevent the swing. Further, the shock generated at the time of contact is alleviated by the cushion member 40 c.
A support arm portion 42a of the panel body guide 42 is fixed to a side surface of the vertical frame 4ap of the one panel body 4a passing above the floor guide 40. The U-shaped central portion of the plate guide 42 extends toward the other plate 4a, and the locking arm portion 42b is positioned between the play prevention members 15 of the other plate 4 a. Further, it is preferable that: a recess 4ab1 is also formed in the bottom surface of the lower frame 4ab of the other plate body 4a, and the cushion member 42c is inserted into the recess 4ab 1.
The plate body 4a passing above the cushion holding portion 42b1 of the plate body guide 42 moves in a state where the cushion holding portion 42b1 and the gap preventing member 15 or the recess 4ab1 are connected. Therefore, when the plate body 4a passing above the cushion holding portion 42b1 of the plate body guide 42 attempts to swing, the cushion 42c of the cushion holding portion 42b1 abuts against the play prevention member 15 or the recess 4ab1 to stop the swing. Further, the shock generated at the time of contact is alleviated by the cushion member 40 c.
