Description

  The present invention relates to a structure that rotatably connects side end portions of panels such as a partition panel configured by connecting a plurality of panels.

  As a partition panel for partitioning the space, the side edges of the panels are connected via hinges, and the panels are provided to be rotatable in both forward and reverse directions around the hinges, as shown in FIG. In some cases, the panels P are folded and stored in the storage S, and a necessary number of panels P are drawn out from the storage S onto the floor for use.

Since such a partition panel is connected so that the panels P can be freely rotated by the hinge portion H, a plurality of panels P can be installed so as to be a straight surface, It was difficult to fold and install the Ps at right angles or other predetermined angles.
Therefore, as a means for maintaining the panels P at a predetermined connection angle, as shown in FIG. 15 (A), a hinge B that slides on the upper surface of the end of the panel P is used, and this is sandwiched between the hinges H. The cover P is inserted into the end portion of the adjacent panels P connected in the above-mentioned manner, and the panels P are fixed to be flush with each other (for example, refer to Patent Document 1), or as shown in FIG. C was used, and this was mounted between the upper ends of the panel P so as to regulate the connection angle of the panel P.

JP 2001-262746 A

  Among the above-mentioned conventional techniques, the one using the crown B can fix the adjacent panels P in parallel, but cannot fix them at other connection angles. Further, in order to fix the panel P with the hood B, it is necessary to perform a troublesome operation of extending the hand to the upper surface of the panel and sliding the hood B while supporting the adjacent panel P in parallel. Furthermore, since it is only possible to check whether or not the panel P is fixed on the upper surface of the panel, it is possible to rotate the erroneously fixed panel P without noticing the state where the panel P is fixed. When this is added, a large load is applied to the engagement portion of the yoke B due to the lever principle, and there is a problem that the yoke B is easily damaged.

  In addition, in the case of using the cover body C, the number of cover bodies C to be attached to each hinge portion H, that is, (total number of panels −1) cover bodies C, is prepared. In addition to the panel P, a place to manage and labor are required. Also, the operation of fixing the panel P with the cover body C is carried out by the troublesome procedure of extending the hand to the upper surface of the panel and attaching the cover body C while supporting the adjacent panel P in the same manner as described above, and is fixed by one-touch operation. It was not of a structure that could be done.

  Residential movable partition panels are used by residents to divide indoor spaces flexibly according to various living scenes, for example, to partition the living room when there are sudden visitors, and are frequently used in daily life. The panel is folded and the panel surface is deformed. It takes a lot of time to set the connection angle of the panels, which is inconvenient when it becomes necessary to partition the room suddenly. If the angle is not fixed and the connected panel surfaces are wavy, the appearance is bad and the appearance is not preferable. Therefore, it is desirable that anyone can quickly and accurately set the panel rotation and setting and fixing the connection angle with a simple operation.

  In the present invention, in view of such problems of the prior art, when the panels are rotatably connected, the connected panel is accurately rotated to a desired angle and fixed at the rotational position. It is an issue to be able to keep it.

In order to solve the above-mentioned problems, the panel connection structure of the present invention is such that the side end portions of the panels having arcuate curved portions on the end faces are mutually abutted while the side end portions of both panels are butted against each other with the rotation assisting member. A panel connection structure that is supported so as to be able to rotate around a side end portion, and a multi-surface contour-shaped angle regulating member having a protruding portion that protrudes to the side from the outer periphery of the curved portion. By providing the end portions with the peripheral surfaces joined to each other, the rotation of the panel is restricted by the engagement between the raised portion of the angle restricting member and the peripheral surface of the angle restricting member opposed thereto, and over the raised portion. The pivoted panel is provided so as to be held at a pivot position where the angle regulating members are surface-joined with each other.
The rotation assisting member spans between the centers of the curvature radii of the outer periphery of the curved portion so as to mesh with each other along the curved outer periphery of the side end portions, and a connecting member that rotatably supports the panel side end portions. It can comprise by the gear member which arranged the uneven | corrugated streak.
In addition, at least the raised portion of the angle restricting member can be elastically deformed, and at least the bearing portion of the connecting member can be elastically deformed so that the panel turning operation over the raised portion of the angle restricting member can be easily performed. May be.

In the above configuration, the arc-shaped curved portion provided at the side end portion of the panel is a curved surface shape in which one side is curved in a circular arc shape with a radius of curvature that is approximately ½ of the panel thickness on the other side. The semi-cylindrical end material as described above can be integrally attached to the flat-side processed end surface of the panel.
The side end face of the panel itself may be processed into a curved shape that is curved in an arc shape with a radius of curvature that is approximately ½ of the thickness of the panel.
Panels to be connected have the same thickness, and both side end portions are provided on curved surfaces bulging sideways with a radius of curvature that is approximately ½ of the panel thickness.

The rotation assisting member connects the panels whose side ends are abutted to each other by joining the peripheral surfaces of the both side ends, and vertically around the side end of the partner panel connected to each other with the side ends joined. It is provided so as to be pivotable in both forward and reverse directions around the axis.
For example, the rotation assisting member is provided with a cylindrical shaft portion at the center of the curvature radius of the outer periphery of the curved portion of both the panel side ends to be connected, and an arrangement interval approximately twice the curvature radius on the oval plate material. The connecting member formed with a pair of circular holes is inserted into both the circular holes and spanned between the two shaft parts, and the connecting members are rotatably supported by the two shaft parts. A gear member provided with uneven stripes along the outer periphery of the curved portion is fixed to the side end portions of both panels, and the side end portions can be joined by engaging the uneven stripes of both gear members.
If the panel side end and the other panel side end shift in parallel and function so as not to cause a discrepancy when the panel is rotated, the rotation auxiliary member uses a member other than the above. It is configured appropriately.

The angle restricting member is formed in a multi-surface contour shape in which a plurality of raised portions and joint surface portions are connected to the peripheral surface, and, like the gear member, the peripheral surfaces are joined to each other on both panel side ends to be integrally fixed. Is done.
Specifically, the raised portion is provided at the boundary between the joint surface portion and the joint surface portion, and the bulge portion slightly swells from the outer peripheral arc of the curved portion at the panel side end portion with the angle regulating member attached to the panel side end portion. And the joint surface part are arranged at positions along the outer peripheral arc of the curved part at the panel side end part. The joint surface portions of the angle regulating members attached to both panel side end portions are provided so as to be surface joined without applying stress to the panel connecting portion.

When the panel is rotated in a state where the bonding surface portions are surface-bonded, the protrusions collide with and engage with the peripheral surfaces of the angle-regulating members facing each other, so that the rotation of the panel is restricted. Both panels are held in the mated position.
When the panel is further rotated by applying force, the panel is rotated to the position where the adjacent joining surface parts connected to the raised part are surface-joined by overcoming the raised part due to the bending and elasticity of the members constituting the connecting part. At this time, the panel operator can know the rotation state of the panel with a click feeling over the raised portion.

  In order to absorb the interference with the circumferential surface of the angle restricting member facing the raised portion when the turning operation over the raised portion is performed, the raised portion of the angle restricting member is formed of an elastically deformable member, or the rotation assist If the connecting members of the members are formed of elastically deformable members, the horizontal stress applied to the contact surface when the ridges are overcome is elastically deformed and absorbed by these members, and the click feeling is not impaired. A rotating operation can be obtained.

  The joint surface portion of the angle regulating member can be appropriately provided at a position corresponding to the rotation angle of the panel, such as a position where the panels are joined flush with each other (0 °), a position bent at a right angle (90 °), and the like. . For example, if a plurality of positions are provided on the peripheral surface of the angle restricting member on both sides of the position where they are joined flush with each other at intervals of 30 °, the panel is rotated about the vertical axis by 30 ° in both forward and reverse directions. The panel can be fixed with. Further, the joint surface portion can be formed in an appropriate shape such as a vertical plane or a curved surface. When the joint surface portion of one angle restricting member is a curved concave surface, the joint surface portion of the other angle restricting member facing is a curved convex surface.

  According to the panel connection structure of the present invention, the panel can be rotated in both forward and reverse directions around the vertical axis while the side end portion is joined around the side end portion of the connected counterpart panel, and the angle regulating member. By engaging the peripheral surfaces of the angle restricting members facing each other, the panel can be fixed at a position where the joint surface portions of the angle restricting members are surface-bonded to each other. It is not necessary to use a separate member for fixing the panel or perform a special operation. Then, if the panel is rotated by applying a force sufficient to overcome the ridge, the panel can be rotated by a simple operation to the position where the adjacent joint surface portion connected to the ridge is in a surface-joined state. The panel can be held at the connecting angle at the position.

  As shown in FIGS. 1-6, the panel connection structure of this invention connects the side edge parts of the panel P so that rotation is possible, and the end material 2, 2, the rotation auxiliary member 3 and the angle regulating members 4, 4 are arranged respectively.

  As shown in FIG. 1, the end members 2 and 2 have substantially the same thickness as the panel P, one side is a plane that is surface-bonded to the side end surface of the panel P, and the other side is approximately 1 / th of the thickness (D) of the panel P. 2 is a semi-cylindrical plate formed on a curved surface curved in an arc shape with a radius of curvature (R) of 2, and is fixed integrally to the side end surfaces of the panels P and P, respectively, An arcuate curved surface is formed. The end members 2 and 2 are respectively divided into upper and lower portions on the upper side of the panel side end portion 1, and gear members 31 and 31 of a rotation assisting member are integrally attached therebetween.

The rotation assisting member 3 is provided by gear members 31, 31 that are mounted in the gaps divided above and below the end members 2, 2 and a connecting member 32 that spans between both gear members and connects the end members 2, 2. It is configured.
Specifically, as shown in FIG. 1 and FIG. 2, the gear members 31, 31 are curved with the top surface 31 a covering the divided end surface of the end material 2 and the radius of curvature (R), and the outer periphery of the end material 2. The upper gear 311 and the lower gear 312 are formed in the same shape with the side surface 31b covering the surface, and the upper and lower gears are arranged with the top surface 31a facing each other in the upper and lower divided gap portions of the end member 2, respectively. The end material 2 is integrally fixed. A semicircular protrusion 31c is provided at the center of the radius of curvature (R) on the top surface 31a, and a cylindrical shaft portion that rotatably supports the connecting member 32 in a state where the upper and lower gears are butted together. 31d is configured. Further, the side surface 31b is provided with uneven stripes 31e extending vertically.
The connecting member 32 is formed by providing circular holes 32a and 32a at both ends of an oval plate material at an arrangement interval approximately twice the radius of curvature (R). The connecting member 32 is bridged between the gear members 31 and 31 integrally fixed to the end members 2 and 2, and the shaft portions 31 d and 31 d are inserted into the circular holes 32 a and 32 a fitted between the upper and lower gears 311 and 312. Thus, both ends are rotatably supported by the shaft portions 31d, 31d of the gear members 31, 31 and attached.

As shown in FIG. 3, the rotation assisting member 3 configured as described above meshes with the side surface irregularities 31 e and 31 e of the gear members 31 and 31 fixed to the panel side end portions 1 and 1, respectively. Both ends of the connecting member 32 are rotatably supported by the shaft portions 31d and 31d of the gear members 31 and 31, so that the panel side end portions 1 and 1 are rotatable in a state where the peripheral surfaces abutting each other are joined. Connect to
Both panel side end portions 1 and 1 are rotatable around the shaft portions 1d and 1d, and the peripheral surfaces are joined by engaging the concave and convex lines 31e and 31e without opening a gap. As shown in FIG. 4, the panels P and P can be rotated relative to each other in both the forward and reverse directions around the side end portion 1 of the counterpart panel P around the vertical axis while the peripheral surfaces are joined. It has become.

The angle regulating members 4, 4 are formed in the same shape by projecting a multi-sided contoured side surface 4 b downward in a skirt shape from a top surface 4 a covering the upper end of the end material 2, and the upper ends of the end materials 2, 2 respectively. It is fixed to the unit.
Specifically, as shown in FIG. 5, the side surface 4 b of the angle regulating member 4 has a flat joint surface 41 extending vertically and has a bending angle of 120 ° with each other along the outer peripheral arc of the curved portion of the end material 2. As a result, a plurality of ridges 42 are arranged at the bends between the joint surfaces and are slightly swollen than the outer peripheral arc of the curved portion and protrude to the side. It is formed so as to have a peripheral surface shape obtained by substantially dividing a square. Further, each of the raised portions 42 arranged on one half of the side surface 4b is provided with a recess 42a at the protruding portion at the tip.

  The angle restricting members 4 and 4 are fixed integrally with the upper ends of the end members 2 and 2 by joining the peripheral surfaces thereof. As shown in FIG. 5, the joint surface portions 41 and 41 at the outer peripheral tips of the side surfaces 4b are in contact with each other. In the combined state, the panel side end portions 1 and 1 are abutted straight to support the panels P and P in parallel, and when the panel P is rotated from this state, both sides of the joint surface portion 41 are supported. Since the raised portions 42, 42 collide with and engage with the opposed raised portions 42, 42, the rotation of the panel P is restricted, and the panels P, P are fixed at the positions where the joined surface portions 41, 41 are surface joined. It ’s just like you ’re going.

When the panel P is rotated with increasing force, as shown in FIG. 6 (A), the raised portion 42 on one side is immersed in the recessed portion 42a of the raised portion 42 on the other side, and the raised portion 42 is moved. The stress acting between the shaft portions 31d and 31d is absorbed by the bending and elasticity of the member that overcomes the connecting portion, and as shown in FIG. The panels P and P are rotated to the position where they are to be held, whereby the panels P and P are held at a connection angle of 90 °. Even at this connection angle, when the panel P is to be rotated, the raised portions 42 and 42 on both sides of the joint surface portion 41 collide with and engage with the opposed raised portions 42 and 42, so that the rotation of the panel P is restricted. Both panels P, P are fixed at the position where the joining surface portions 41, 41 are surface joined.
When the panel P is further rotated by increasing the force, as shown in FIG. 4C, the opposite raised portions 42 are immersed in the concave portions 42a of the raised portions 42 on the other side in the same manner as described above. As shown in FIG. 4D, the joint surfaces 41 and 41 are surface-joined and the panels P and P are rotated to a position where the panels P and P are folded in parallel. P is held at a connection angle of 180 °.

In such a series of rotation operations, when the raised portions 42 and 42 that press-contact each other's outer peripheral surfaces are interchanged and get over the raised portion 42, a click feeling is obtained, and the panel operator knows the state of the rotated operation. Can do.
Further, since the concave portion 42a is provided in the raised portion 42, it is possible to rotate the panel P by applying a necessary minimum force without impairing the function of restricting the rotation of the panel P. That is, when the raised portion 42 has a large corner as shown in FIG. 7A, when the panel P is rotated, the interference between the raised portions 42 and 42 (arrow A in the figure) increases. In order to absorb the stress caused by the interference, a large force is required for the turning operation over the raised portion 42. On the other hand, as shown in FIG. 4B, in the raised portion 42 provided with the recess 42a, both sides of the recess 42a have small corners, and the interference margin between the raised portions 42, 42 (arrow B in the figure) becomes smaller. Thus, the rotation operation over the raised portion 42 can be performed with a small force, and even if the interference is small, the rotation of the panel P in any direction is restricted by being arranged at the end of the joint surface portion 41. The

  Thus, according to the panel connection structure of the present invention, the panel side end portions 1 and 1 are connected to each other by the rotation assisting member 3, and the panel side end portion around the side end portion 1 of the connected counterpart panel P is connected. The panel P is supported rotatably around the vertical axis while the members 1 and 1 are joined to each other, and the peripheral surface is used without using another member for fixing the panel P or performing a special operation. It is possible to fix the panels P and P at a predetermined connection angle in accordance with the joining state of the angle restricting members 4 and 4 each having the raised portion 42.

  In the panel connection structure having the above-described configuration, as shown in FIG. 8, the angle regulating member 4 is provided with a concave portion 42a on the raised portion 42 on one half surface of the side surface 4a, and a convex portion 42b on the raised portion 42 on the other half surface. If the raised and lowered portions 42 and 42 are provided so that the concavo-convex portions are joined to each other, the turning angle is restricted, while the interference between the raised portions 42 and 42 is reduced, and the turning operation is stable with a smaller force. Can be obtained.

Further, as shown in FIG. 7A, when the protruding portion 42 of the angle regulating member 4 has a large corner, the protruding portion 42 is overcome in order to absorb the stress caused by the interference between the protruding portions 42 and 42. A large force is required for the turning operation.
In such a case, if the connecting member 32 of the rotation assisting member 3 is formed of an elastic material such as rubber or synthetic resin to have elasticity, stress caused by interference between the raised portions is caused between the shaft portions 32d and 32d. Therefore, the coupling member 32 can be absorbed by elastic deformation, and the angle can be reliably controlled and the rotation operation can be performed with a small force. Even if the whole connecting member 32 is not formed of an elastic material, as shown in FIG. 9A, if the packing 33 made of an elastic material such as rubber is attached to the bearings of the circular holes 32a and 32a, the packing 33 is used. Can absorb stress.
Further, the entire angle regulating member 4 is molded from an elastic material such as rubber or synthetic resin, or as shown in FIG. 5B, the raised portion 42 of the angle regulating member 4 is molded from an elastic material, You may provide so that stress may be absorbed by the elastic deformation of angle control member 4 itself.

  Further, the angle restricting members 4 and 4 disposed to face each other do not necessarily have the same shape. For example, as shown in FIG. 10, the angle regulating member 4 on one side is formed by providing a concave portion 42a on each raised portion 42, and the angle regulating member 4 on the other side is formed by providing a raised portion 42b on each raised portion 42. And when the panel P is rotated, you may provide so that the recessed part 42a and convex part 42b of the protruding parts 42 and 42 which oppose may mutually join.

  Furthermore, the joint surface portion 41 of the angle regulating member 4 does not necessarily have to be formed by a flat surface. For example, as shown in FIG. 11, each joint surface portion 41 of one side angle regulating member 4 is formed as a concave surface 41 a, each joint surface portion 41 of the other side angle regulating member 4 is formed as a convex surface 41 b, and the panel P is rotated. Sometimes, it may be provided so that the panel P is held at the connection angle by surface bonding of both the uneven surfaces.

  Further, the rotation assisting member 3 includes gear members 31 and 31 and a connecting member 32. For example, as shown in FIG. It spans between them and connects both ends of the material so that it can rotate. Using the intersecting part of each belt 34 as a fulcrum, it turns around the vertical axis with the ends 2 and 2 curved against each other. You may comprise so that it can do.

  As shown in FIG. 13A, if the rotation assisting portion 3 and the angle regulating member 4 are respectively installed at the upper and lower portions in the panel side end portions 1 and 1, stable rotation operation can be obtained. However, it may be installed at other locations. When the rotation assisting member 3 is configured using the connecting member 32, the connecting member 32 is preferably provided at a plurality of locations. Further, as shown in FIG. 5B, the angle regulating member 4 is provided at one central position in the panel side end portions 1 and 1, and the rotation assisting members 3 and 3 are provided at both upper and lower ends thereof. Also good.

  The angle restricting member 4 of the illustrated form is provided so that the joint surface portions 41 are connected to each other with a bend angle of 120 °, and the connection angle of the panel P is provided to be restricted by 90 °. For example, the rotation and restriction angles can be set as appropriate, such as providing the connection angle to be regulated by 30 ° or 45 °.
