JP5103537B2 - Runner, traveling unit and open / close shielding structure - Google Patents

Description

  The present invention relates to a runner useful for traveling a rail such as a curtain rail, in particular, a runner having a traveling member with respect to a shaft portion of the runner (for example, in order to close a curtain in a form in which curtain ends are overlapped). And a traveling unit (rail traveling unit) including the runner, and an opening / closing type shielding structure (or opening / closing device).

  A runner can be run on a rail, such as a curtain rail with a hollow cross-section that opens narrowly along the longitudinal direction, and a shield member (shield sheet such as a panel or curtain) is suspended from this runner. A shield structure that can be opened and closed is used.

  For example, in Japanese Patent Laid-Open No. 2000-2038 (Patent Document 1), a support shaft to which a panel or the like can be attached, a pair of upper and lower rollers rotatably provided on the support shaft, and the support shaft and the roller are provided. There is disclosed a cross runner including a ball (bearing) interposed therebetween and a flange portion that clamps the ball in the direction of the rotation center axis of the roller in association with the roller.

  Such a runner has a panel attached to the lower part of the spindle of the runner, the lower part has a narrow opening, and is disposed in a cross-section hollow rail having a running surface on both sides of the opening. The panel is opened and closed by rolling and running on the running surface.

  Runners that can run along curtain rails are also known. The runner usually includes a roller shaft, a pair of rotatable rollers attached to both sides of the roller shaft via bearings, a support body that rotatably supports the roller shaft, A support shaft attached to a lower portion of the support shaft so as to be freely rotatable in the circumferential direction, and a mounting member attached to the lower end portion of the support shaft to suspend the curtain (for example, an annular ring, a hook) Etc.).

  However, such a runner is arranged in a rail having a narrow opening at the bottom, and a roller is run along the running surface on both sides of the opening while a shielding sheet such as a curtain is suspended. When an oblique force is applied to the vertical direction, the runner's shaft core is inclined and the shielding sheet cannot be opened and closed smoothly. In particular, when the shielding sheet is opened and closed by hand, a force in an oblique direction with respect to the vertical direction is likely to act on the runner, and the shielding sheet cannot be smoothly opened and closed.

  In Japanese Patent Laid-Open No. 2001-73627 (Patent Document 2), as a joiner runner that does not cause the swinging of the hanging door in the front-rear direction, the hanging shaft and the upper end of the hanging shaft are pivotally supported by the shaft. There is disclosed a runner for joinery that includes a pair of front and rear rollers, and has a specific shape in a maximum diameter portion of the front and rear rollers and a cross-sectional shape of the outer periphery of the roller.

  JP 2000-160917 A (Patent Document 3) relates to a runner that suspends and supports a door panel, in order to prevent the runner from slipping or meandering due to an offset load such as a tilting moment. There is disclosed a suspension type runner having a pair of front and rear roller shafts supported by a runner body and four front and rear and left and right rollers supported by the roller shafts and freely rotatable via angular bearings.

  However, these runners are complex in structure or shape. In addition, when the runner is disposed with play (especially large clearance) in a hollow rail having a narrow opening at the bottom, the runner is caused by the action of a force oblique to the vertical direction. As a result, the shielding core (panel, curtain, etc.) cannot be opened and closed smoothly. Therefore, in order to prevent the runner from meandering or laterally shifting in the rail having a hollow cross section, it is necessary to dispose the runner in the rail with a relatively narrow gap.

  A runner is also known in which a traveling member (or a guide member) is connected to the lower portion of the support shaft of the runner, and a shielding member (such as a curtain) is suspended from the traveling member via an engagement member such as a hook member. ing. In particular, in a cross runner or cross runner (cross string pulling runner, etc.) in which the end of a shielding member (curtain, etc.) is overlapped and closed, the leading portion in the running direction is bent to overlap with each other. A pair of elongate traveling members (or guide members) capable of crossing are attached at a predetermined interval, and these runners are arranged in one rail. When a horizontal tension is applied to the shielding member while applying a force in the vertical direction of the support shaft of the runner, the shielding member can be smoothly opened and closed. However, if an oblique force is applied to the runner's support shaft as the shield member opens and closes, the runner roller may be prevented from rotating, and the shield member cannot be opened or closed. The opening and closing operability of the is significantly reduced. In particular, when the shielding member is opened and closed manually (or manually), an oblique force tends to act on the runner. Therefore, the opening and closing operation of the shielding member (curtain, etc.) becomes extremely difficult, and the shielding member is simple and smooth. Cannot be opened or closed.

JP 2000-2038 A (claim, paragraph [0029], FIG. 1, FIG. 5) Japanese Patent Laying-Open No. 2001-73627 (Claims, FIGS. 3 and 4) JP 2000-160917 A (Claims, FIG. 1)

  Accordingly, an object of the present invention is to provide a runner that can smoothly travel along a rail even when an oblique force is applied to the runner's axis, a travel unit including the runner, and an open / close shielding structure. There is.

  Another object of the present invention is to provide a runner that can smoothly travel in the rail even when the runner is disposed in the rail with a large gap, a travel unit including the runner, and an open / close type shielding structure.

  Still another object of the present invention is a configuration in which a traveling member (for example, one rail can be traveled in a direction relatively close to each other and the leading portions in the traveling direction can overlap each other below the runner's support shaft. It is an object of the present invention to provide a runner that can stably and smoothly travel along a rail even if a pair of elongated travel members bent to each other is attached, a travel unit including the runner, and an open / close shielding structure.

  As a result of intensive studies to achieve the above-mentioned problems, the present inventors have found that when a force in an oblique direction acts on the support shaft of the runner in the manual opening / closing operation, the runner support shaft is moved to the side wall of the opening of the rail (particularly The opening and closing of the shielding member is greatly impaired, and the portion corresponding to the side wall of the rail opening of the runner's support shaft is rotatable in the circumferential direction of the support shaft. It has been found that when a ring member (such as a ball bearing) is provided, the shielding member can be opened and closed stably and smoothly, and the present invention has been completed.

  That is, the runner of the present invention has a rail (for example, a rail having a hollow cross section) having a narrow opening formed in the lower portion and a running surface formed on both sides of the opening along the longitudinal direction. ). The runner includes a roller that can roll on the running surface; a roller shaft that pivotally supports the roller; a support portion that rotatably supports the roller shaft; And a suspension member for suspending the shielding member; and a ring member disposed on the support portion corresponding to the opening so as to be rotatable in the circumferential direction of the support portion. . In such a runner, the roller may be constituted by a pair of rollers, and the support portion may be constituted by a shaft portion. For example, the support portion may include a shaft portion that rotatably supports the roller shaft between a pair of rollers; a suspension member may be attached to the shaft portion; and the shaft portion corresponding to the opening portion In addition, the ring member may be disposed so as to be rotatable in the circumferential direction of the shaft portion. Further, the ring member may be constituted by at least one ball bearing that is rotatable in the circumferential direction of the support portion.

  In such a runner, even if a force from an oblique direction acts on the runner and the support portion (or the shaft portion) comes into contact with the side wall of the opening of the rail, the contact with the side wall of the opening causes the support portion (or Since the ring member (or ball pairing) disposed in the shaft portion rotates, the runner smoothly travels on the traveling surface of the rail without engaging the rail.

  The rail has a pair of side walls facing each other at a predetermined interval and forming an opening; and an upper running wall and a lower regulating wall extending in opposite directions from the pair of side walls. A traveling unit may be provided.

  The suspension member is attached to a support portion of the runner (for example, an end portion of the support portion) and travels along with the runner (or a guide member); for attaching a shielding member to the travel member And an attachment member. The shielding member may be attached to the traveling member so as to be swingable by the attaching member. The suspension member is attached to the end of the support portion of the plurality of runners, and is an elongated traveling member (or guide member) that travels with the runner; and is rotatably attached to both side portions of the traveling member. And a rotating member (for example, a rotatable roller) that can come into contact with the lower surface of the lower wall (lower regulating wall) of the opening of the rail as the support portion tilts; An attachment member for attaching the shielding member so as to be swingable may be provided. Further, a roller capable of traveling on a traveling surface of the upper traveling wall of the upper traveling wall, a ball bearing attached to a support portion corresponding to the pair of side walls, and attached to the support portion, travels with a runner. An elongated traveling member (or a guide member) and a rotational member (for example, a roller) that is pivotally attached to both side portions of the traveling member and that can come into contact with the lower surface of the lower regulating wall as the support portion tilts. , Wheels, etc.). In a runner equipped with such a rotating member (for example, a roller), the rotating member (for example, the roller) can contact the lower wall (lower regulating wall) of the opening of the rail even if the support portion is inclined. Therefore, the rail can be stably driven while maintaining a predetermined posture.

  Furthermore, the suspension member may include a pair of traveling members (or guide members) capable of traveling in the direction in which one rail is relatively close to each other, and the leading portion of the pair of traveling members in the traveling direction. May be bent and overlap each other. When such a pair of traveling members are arranged so as to be able to travel on one rail via a runner and are moved in directions approaching each other, the leading portions in the traveling direction can overlap and intersect. Therefore, by attaching a shielding member (such as a curtain) to the pair of traveling members, the leading portion (end portion) of the shielding member can be overlapped and closed.

  A traveling unit of the present invention includes a rail (such as a rail having a hollow cross section) having a narrow opening formed in a lower portion and traveling surfaces formed on both sides of the opening along the longitudinal direction. A travel unit comprising a runner capable of traveling along the rail, the runner rolling on the travel surface and capable of traveling (for example, a pair of rollers); A roller shaft that is movably supported; a support portion that rotatably supports the roller shaft; a suspension member that is attached to the support portion and that suspends the shielding member; and corresponds to the opening And a ring member rotatably attached to the support portion. In this traveling unit, the rail has a pair of side walls facing each other at a predetermined interval and forming an opening, and an upper U traveling wall and a lower regulating wall extending in opposite directions from the pair of side walls. A roller capable of traveling on the traveling surface of the upper traveling wall, a ball bearing mounted on a support corresponding to the pair of side walls, and a lower regulating wall on both sides. You may have the suspension member provided with the rotation member (a roller, a wheel, etc.) which can be rotated in contact with a lower surface.

  The open / close type shielding structure of the present invention includes the traveling unit and a shielding member that is suspended by a suspension member and that can be opened and closed along a rail. The suspension member may include a pair of traveling members (or guide members) capable of traveling in the direction in which one rail is relatively close to each other, and the leading portions of the pair of traveling members in the traveling direction are bent. , They may overlap each other. Further, the shielding sheet may be hung on the pair of traveling members, and the leading portion of the shielding sheet may overlap (or be superposable) with each other as the pair of traveling members travel.

  In the present invention, a ring member (such as a ball bearing) that is rotatable in the circumferential direction of the support shaft is disposed in a portion of the runner support shaft that corresponds to the side wall of the opening of the rail. Even if an oblique force is applied to the core, it can travel smoothly along the rail. Moreover, even if a runner is disposed in the rail with a large gap, the rail can be smoothly traveled. Furthermore, even if the traveling member is attached to the lower part of the support shaft of the runner, it can travel stably and smoothly along the rail. In particular, as a traveling member, for example, a pair of elongate traveling members that are capable of traveling in a direction in which one rail is relatively close to each other and whose leading portions in the traveling direction can be overlapped with each other are used, The runner can run smoothly along the rail. Therefore, the shielding member such as the curtain can be opened and closed smoothly.

  In the example shown in FIGS. 1 to 4, the openable / closable shielding structure (or the openable / closable shielding device) includes a rail (guide rail) 1 having a pair of traveling paths (traveling surfaces) spaced apart from each other by a predetermined distance. The runner 11 is disposed so as to be able to run, and a sheet-like shielding member (curtain or the like) 34 attached to the runner. In this example, an opening / closing device having a cross runner (crossing runner) (an opening / closing device having a manual or a manual runner) is shown.

  As shown in FIG. 2, the rail 1 has a hollow section with a narrow opening 2 formed in the lower portion along the longitudinal direction, and the pair of travel paths (travel The surface) is formed by a pair of running portions 3a and 3b having a U-shaped cross section with the opening 2 interposed therebetween. That is, the rail 1 has a pair of side walls 4a and 4b that face each other at a predetermined interval and form an opening 2, and upper running walls 5a and 5b and a lower regulating wall that extend in opposite directions from the pair of side walls. Traveling portions 3a and 3b having a U-shaped cross section provided with 6a and 6b are provided. Further, the outer walls 7a and 7b and the upper wall 8 of the rail 1 are formed in a U-shaped cross section from the ends of the lower regulating walls 6a and 6b. In this example, the upper traveling walls 5a and 5b are formed in a curved shape by bending from the opening 2 toward the outside (opposite direction).

  The runner 11 disposed in the rail 1 includes a runner body 12 capable of traveling on the traveling surfaces (upper surfaces) of the upper traveling walls 5a and 5b of the rail 1, and a shield member 34 attached to the runner body. And an elongated suspension member 21 for suspension. The runner body 12 includes a pair of rollers 13a and 13b that can run by rolling on the running surfaces of the upper running walls 5a and 5b, and a roller shaft 14 that pivotally supports the pair of rollers on both sides. And a support portion 15 that rotatably supports the roller shaft between the pair of rollers 13a and 13b (center portion in the axial direction of the roller shaft). A ball bearing (not shown) is interposed between the rollers 13a and 13b and the roller shaft 14 for the rotation and rolling of the rollers 13a and 13b. Since such a runner 11 has a structure which supports between a pair of rollers 13a and 13b with the support part 15, a structure can be simplified or made compact.

  As shown in FIG. 4, the support portion 15 includes a head portion 16 for attaching the rollers 13a and 13b by the roller shaft 14, and a shaft portion 17 having a circular cross section extending from the head portion. The shaft portion is formed such that its diameter gradually decreases toward the distal end portion, and a base portion 17a adjacent to the head portion 16 extends from the base portion, and the side walls 4a, The mounting portion 17b includes a portion corresponding to 4b, and a fixing portion 17c that extends from the mounting portion and is integrated with the suspension member 21. Of the mounting portion 17b, ball bearings 18a and 18b that are mounted adjacent to the side walls 4a and 4b of the rail 1 in the axial direction and are rotatable in the circumferential direction of the shaft portion 17. And a washer 19 is attached adjacent to the ring member 18. The elongated suspension member 21 is provided with support portions 15 of a plurality of runner main bodies 12 attached at intervals in the longitudinal direction of the suspension member 21, and ends of the support portions 15 of the runner main bodies 12. The (fixing portion 17c of the shaft portion 17) is pushed into a hole formed in the suspension member 21, and is fixed to the suspension member 21 by caulking or the like.

  A suspension member 21 attached to the fixing portion 17c of the support portion 15 is attached to an end portion of the support portion 15 (or the shaft portion 17) of the runner body 12 and travels along with the runner body 12. Long (or elongated) plate-like traveling members (or guide members) 22a, 22b, and lower restricting walls 6a of the opening 2 of the rail 1 that are rotatably attached to both side portions of the traveling member. A pair of rotating members (rollers) 23a, 23b that can come into contact with the lower surface of 6b, and a roll shaft 24 that passes through the travel member and pivotally supports the pair of rotating members (rollers) 23a, 23b. Yes.

  In this example, the pair of runners 11 (runner main body 12) are spaced apart from each other in the longitudinal direction of the suspension member 21 (or travel members (or guide members) 22a, 22b). (Or guide members) 22a, 22b) are attached to the subsequent side (reference portion B described later). The rotating members 23a and 23b are attached to the traveling members (or guide members) 22a and 22b adjacent to the runner main body 12 on the subsequent side (at a position close to the attachment portion of the runner main body 12). In addition, the outer peripheral surfaces of the rotating members 23a and 23b are located at a predetermined distance from the lower surfaces of the lower regulating walls 6a and 6b of the rail 1. And when the force of the diagonal direction acts with respect to the support part 15 (or axial part 17) of the said runner main body 12, with the inclination movement of the support part 15 (or axial part 17), the said rotation member 23a, 23 b can contact the lower surfaces of the lower regulating walls 6 a and 6 b of the rail 1. Therefore, the excessive inclination of the runner 11 in the rail 1 can be regulated by the rotating members 23a and 23b, and the traveling path of the rail 1 can be stably traveled while maintaining the posture of the runner 11. That is, the rotation members 23 a and 23 b function as a travel stabilization member, and prevent the runner 11 from moving up and down and sideways with respect to the rail 1.

  The pair of travel members (or guide members) 22a and 22b can travel in the direction in which one rail 1 is relatively close to each other in a known form, and the leading portions in the travel direction are bent and overlap each other. It is possible to intersect (can intersect in overlapping form). That is, the pair of travel members (or guide members) 22 a and 22 b can travel along the runner 11 in a direction in which one rail 1 is relatively close to each other, and along the opening 2 of the rail 1. A reference portion B that extends linearly, a leading portion L that is bent from the reference portion and extends linearly in parallel with the reference portion B, and is opposite to the leading portion L at the other end of the reference portion B. And a trailing portion F that is bent in a direction and extends linearly in parallel with the reference portion B. Further, the bent portion from the reference portion B to the leading portion L is a restricting portion (abutting portion) for preventing the leading portion L of one traveling member 22a from excessively penetrating in the longitudinal direction of the other traveling member 22b. Wall or collision wall) R is formed. In this example, the length of the trailing portion F is shorter than that of the leading portion L, and the pair of runners 11 (runner main bodies 12) are spaced apart in the longitudinal direction of the reference portion B. It is attached. The rotating members 23a, 23b are adjacent to the runner 11 (runner main body 12) on the rear side of the pair of runners 11 (runner main body 12). Are attached to the reference portion B. Therefore, even if the leading portion L is long and the center of gravity of the traveling members 22a and 22b is close to the leading portion L, the traveling members 22a and 22b are moved back and forth by the rotating members 23a and 23b attached to the reference portion B. It is possible to suppress tilting in the direction.

  Such a pair of traveling members 22a and 22b are attached to a plurality of runner bodies 12 disposed on the rail 1 with the leading portions L facing each other at a predetermined interval in the longitudinal direction of the rail 1. When the pair of travel members 22a and 22b travel in a direction approaching each other, the bent leading portions L and L overlap (or overlap) and intersect along the longitudinal direction of the rail 1 at a predetermined interval in the width direction. .

  Note that an attachment member 31 for attaching the sheet-like shielding member 34 is attached to the suspension member 21 at a predetermined interval in the longitudinal direction. In this example, the attachment member 31 is loosely fitted in the through holes of the pair of traveling members (or guide members) 22a and 22b, and is swingable with respect to the pair of traveling members (or guide members) 22a and 22b. A member 32 and an S-shaped hook member (S ring) 33 that can swingably engage with the ring member are provided. By engaging the hook member (S ring) 33 with a hole 35 a formed in the reinforcing portion 35 on the upper portion of the shielding member 34, the sheet-like shielding member 34 is suspended.

  In such an open / close type shielding structure (or open / close device), a plurality of runners 11 are arranged on one rail 1 with the suspension members 21 (travel members 22a and 22b) directed in a predetermined direction. When a sheet-like shielding member (curtain or the like) 34 is attached to the suspension member 21 (traveling members 22a and 22b), the runner 11 (shaft portion 17) has a portion corresponding to the side walls 4a and 4b of the opening 2 of the rail 1. Since the ball bearings 18a and 18b are mounted, even if an oblique force (traction force) acts on the runner 11 (shaft portion 17) when the sheet-like shielding member 34 is opened and closed in accordance with the guidance, the runner 11 ( The shaft portion 17) travels smoothly without engaging the side walls 4a, 4b of the opening 2. That is, in the manual opening / closing operation of the shielding member 34, the runner 11 can smoothly travel along the rail 1 even if an oblique traction force acts on the runner 11. Therefore, even if the shielding member 34 is a heavy object (for example, a book used in a theater or the like), it can be opened and closed smoothly. Furthermore, the end portion (with a width corresponding to the length of the head portion L) of the shielding member 34 can be closed by using the head portion L of the traveling members 22a and 22b.

  The opening / closing device provided with the runner shown in FIGS. 1 to 4 is not limited to a manual or manual operation for manually opening and closing the shielding member 34, and can smoothly open and close the shielding member 34 even by stringing.

  FIG. 5 is a schematic perspective view showing a shielding structure provided with another runner of the present invention, and FIG. 6 is a schematic diagram for explaining an opening / closing operation of the shielding structure provided with the runner of FIG. In this example, an opening / closing device having an intersection runner (crossing runner) (an opening / closing device having an intersection or cross stringing runner) is shown.

  The opening / closing device of this example is configured in the same manner as the opening / closing device including the runner shown in FIGS. 1 to 4 except that the shielding member is opened and closed by string drawing. That is, in order to move the pair of traveling members (or guide members) 22a and 22b in the direction of approaching or separating along the rail 1, the string 26 is attached to the pair of traveling members (or guide members) 22a and 22b. A string fixing member 25 is attached. In this example, the string fixing member 25 locks the string 26 through the through hole for passing one string 26 from the outside of the side in a ring shape (loop shape). And a fixing portion (not shown) for fixing the string 26 that has passed through the groove with a side outer wall.

  Then, as shown in FIG. 6, one string 26 is passed over one pulley (laterally rotatable pulley) 27 arranged at one end of the rail 1, and branched from this pulley 27. The cords 26a and 26b are disposed on the other end of the rail 1 and are respectively stretched around two pulleys (a pulley adjacent to each other and rotatable in the vertical direction) 28a and 28b. Therefore, when the string 26b located at the other end of the rail 1 is pulled in the direction of the solid arrow, the pair of traveling members (or guide members) 22a and 22b move along the rail 1 in the direction in which they approach each other, and the string 26a Is pulled in the direction of the broken arrow, the pair of travel members (or guide members) 22a and 22b move along the rail 1 in a direction away from each other. Even when such a stringing mechanism or structure is used, the shielding member 34 can be smoothly opened and closed.

[Rail (guide rail)]
In the present invention, the rail (guide rail) has only to have a pair of traveling paths (traveling surfaces) separated by a predetermined distance from the lower opening, and is usually formed in the lower portion along the longitudinal direction. A narrow opening (such as a slit-like opening extending in the longitudinal direction) and a traveling path formed on both sides of the opening. The width of the opening is not limited as long as the runner (in the above example, the shaft portion or the support portion of the runner) can run in a state where the suspended object is suspended. The rail may be open at the top, but is often a rail with a hollow cross section. The rail generally has a U-shaped cross section including a pair of side walls facing each other at a predetermined interval and forming an opening; and an upper running wall and a lower regulating wall extending in opposite directions from the pair of side walls. A traveling part is provided. The upper running wall forms a runner's running path (running surface), and may be curved or flat as described above. The travel path (travel surface) of the upper travel wall is usually smooth. The rail is attached to the predetermined portion by a conventional method.

[runner]
The runner only needs to be able to travel on the rail, and usually travels in a rail having a hollow cross section having a traveling path on both sides of a narrow opening formed in the lower portion. One or a plurality of runners can be arranged for one rail, and usually a plurality of runners are arranged to be able to run. The runner usually has a roller that can run by rolling on the running surface of the rail (for example, the running surface of the upper running wall); a roller shaft that pivotally supports the roller; And a support portion that is rotatably supported.

  Unlike the above-described embodiment, as long as the roller is rotatable, a bearing (hole bearing) may not necessarily be interposed between the roller and the roller shaft. The roller may be composed of a single roller, or may be composed of a pair of rollers as described above. Further, as long as the support portion rotatably supports the roller shaft, the support portion can support an appropriate position of the roller shaft. For example, as described above, the central portion of the roller shaft in the axial direction may be supported by the support portion, and both side portions of the roller shaft may be supported by the support portion. When supporting the central portion of the roller shaft in the axial direction, as described above, the support portion may be configured by a single shaft portion, and the support portion is the central portion of the pair of roller shafts in the axial direction. A support part that supports the vehicle, a branch part that is bent or curved in the front-rear direction of the traveling direction from the support part, and a bifurcated branch part, and an attachment part (attachment shaft portion) that extends from the branch part and to which the suspension member is attached Etc.). In this case, the attachment part may be formed by converging from the branch part to one if necessary. In other words, the support portion may have a ring shape including a support portion for supporting the roller shaft at the upper portion and an attachment portion for attaching the suspension member to the lower portion. Moreover, although this attachment site | part may be curving, in order to make attachment of a suspension member easy, it may have a flat part. In this aspect, a rotatable ring member such as a ball bearing at a part corresponding to the opening of the rail (or a part that may come into contact with the rail), for example, each branch part or attachment part (attachment shaft part or the like). You may wear. In addition, the width | variety of the site | part (each branch site | part, attachment site | part) corresponding to the opening part of a rail is formed smaller than the width | variety of the opening part of a rail.

  Further, when the both sides of the roller shaft are supported by the support portion, for example, the support portion has a base portion having a mounting portion for the suspension member, and bifurcated from the base portion, and supports both side portions of the roller shaft. And a support part. The support portion not only has a simple structure but also improves the runnability of the runner, so that the roller shaft is often supported between a pair of rollers (or both side portions of a single roller). Further, the form of the support portion does not need to be constituted by the head portion and the shaft portion, and at least a support portion that can support the roller shaft, and a ring member that can rotate in the circumferential direction with respect to the axial direction of the support portion It is only necessary to have a mounting part that can be mounted. The support portion usually includes a shaft portion that supports the roller shaft so as to be rotatable (for example, rotatable between a pair of rollers), and a ring member is rotatably mounted on or disposed on the shaft portion. There are many cases to do. In addition, when a support part has a bifurcated shape from a base part and has a support part which supports the both sides of a roller shaft, a ring member respond | corresponds to the opening part (especially both side walls of an opening part). What is necessary is just to mount | wear with or arrange | position to a site | part (site | part corresponding to an opening part among support parts).

  The width of the support portion (shaft portion or the like) is formed smaller than the opening portion of the rail so that the support portion (shaft portion or the like) can smoothly pass through the opening portion of the rail. The ring member that can be mounted on the mounting portion of the support portion only needs to be rotatable in the circumferential direction of the support portion. Of the support portion (or shaft portion), the portion corresponding to at least the opening of the rail ( It suffices if it can be disposed or mounted on a pair of side walls (both side walls) of the opening. Usually, the ring member may be loosely fitted to the support portion (or the shaft portion) and turnable. However, in order to smoothly turn, the ring member is preferably constituted by a bearing. The bearing may be a thrust bearing, but is preferably a radial bearing, and may be a sliding bearing, but is preferably a rolling bearing. A typical bearing is a ball bearing. As is well known, the ball bearing includes an inner ring that is mounted or disposed on the support portion, an outer ring, and a ball that is interposed between the inner ring and the outer ring. The ring is rotatable.

  It is sufficient that at least one ring member (such as a ball bearing) can be mounted or disposed on the support portion (or shaft portion), and a plurality of (2 to 2) adjacent to the support portion (or shaft portion) in the axial direction. Five ring members (for example, two to three) ring members (such as ball bearings) may be mounted or disposed. When a plurality of ring members are mounted in the axial direction of the support portion (or shaft portion), each ring member is rotatable, and therefore a strong oblique force (traction force) acts on the runner's axial direction. Even if the support portion or the like is in contact with the rail, the runner can be stably and reliably driven with respect to the rail.

  FIG. 7 is a schematic sectional view showing the relationship between the rail and another example of the runner body, and FIG. 8 is a schematic exploded perspective view of the runner body shown in FIG. In addition, the same code | symbol is attached | subjected and demonstrated to the same member or element as shown to the said FIGS. 1-4.

  The runner main body 42 in this example has a single roller 43 that can roll and run on the running path of the rail 1, a roller shaft 44 that pivotally supports the roller, and both ends of the roller shaft. And a support frame (support portion) 45 that supports the movable body. The roller 43 is formed such that both side portions in the axial direction are lower than the center portion, and both side portions roll in contact with the upper running walls 5 a and 5 b of the rail 1. The support frame (support portion) 45 is located in the outer peripheral region of the roller 1 and has a frame shape (in this example, a square frame shape) having a pair of support sides 46b that can support both ends between the roller shafts 44. A frame member 46a, a curved side 46d which supports adjacent sides 46c adjacent to the support side 46b of the frame member in a U-shaped form, and is attached to the curved side and is suspended at the end. A shaft portion 47 having a mounting portion for the member 51 is provided. A plurality of ball bearings (ring members) 48a and 48b and a washer 49 are attached to a portion of the shaft portion 47 corresponding to the opening 2 of the rail 1 so as to be adjacent to each other in the axial direction.

  As shown in FIG. 7, the rail 1 includes a pair of side walls 4a and 4b that form the opening 2, and upper running walls 5a and 5b and lower regulating walls 6a and 6b, as described above. Traveling portions 3a and 3b having a U-shaped cross section are provided. Further, the rail 1 is formed by a conventional method, for example, in this example, a recess 1a formed on the front side of the upper portion of the rail 1 is attached to a predetermined portion by a fixing means 63 such as a screw. The positioning is fixed in a state in which the distal end portion of the fitting member 62 is fitted into the concave portion 1b formed in the rear side portion of the upper portion of the rail 1. The engaging member 61 and the fitting member 62 are fastened with bolts and nuts 64 using slide holes (not shown) formed in the fitting member 62.

  Even such a runner (or a runner main body) can smoothly travel on the rail 1 by the hole bearings 48a and 48b of the shaft portion 47, similarly to the runner.

[Hanging member]
The suspension member may be swingably or immovably attached to the support portion in order to suspend the suspension. Therefore, you may comprise a suspension member with the attachment member (The attachment member etc. for attaching a suspended object to a support part so that rocking | fluctuation is possible) mentioned later.

  When the suspension member is fixedly attached to the support portion, the suspension member may be fixed to the support portion by bonding means such as welding or adhesion. In this case, the support portion may be fixed at an appropriate position of the suspension member. As described above, the end portion of the support portion of the runner, for example, the shaft portion of the support portion (such as the fixed portion) is fixed to the suspension member. May be.

[Running member (or guide member)]
The suspension member may include a traveling member (or a guide member) that travels with the runner. This traveling member may be attached to a single runner support (especially the end of the support), or may be attached to a plurality of runner support (especially the end of the support) at intervals. Good. In order to stably travel the traveling member, it is advantageous to attach the traveling member to the support portions of the plurality of runners (particularly, the end portions of the support portions). The traveling member may have a rod shape (round bar shape, square bar shape, etc.), a plate shape, or the like, and a bent or curved portion such as a leading portion is not necessarily required. A traveling member of a form (such as a narrow plate-like member) is used.

  One rail may be provided with one traveling member attached to one or a plurality of support portions, or a plurality of traveling members attached to one or a plurality of support portions may be provided on one rail. The traveling directions of the plurality of traveling members may be the same direction or may be opposite to each other. In addition, the cross runner for closing the curtains in a form in which the ends of the curtains are overlapped is usually a pair of traveling members (or guide members) capable of traveling in a direction in which one rail is relatively close to each other. It has. The leading portions of the pair of traveling members in the traveling direction are bent and can overlap each other. That is, the leading portion of the traveling member is directed to one side portion (leftward or rightward) from the reference portion by the bent portion or the curved portion toward the traveling direction of the runner (the direction in which the traveling shaft and the rail opening extend). It bends or curves to extend in parallel with the run direction of the runner (for example, extends from the reference portion in parallel with the reference portion in an L-shaped form). In this way, the pair of traveling members are arranged on the rail with the leading portions facing each other in a form in which the interval between the leading portions (interval in the direction orthogonal to the traveling direction) is increased (for example, one traveling member) The leading part of the runner bends and extends in the left direction toward the runner's running direction (running axis), and the leading part of the other running member bends and extends in the right direction toward the runner's running direction (running axis) By arranging and traveling in directions that are relatively close to each other, the pair of head portions are overlapped with each other at a predetermined interval. Utilizing this fact, it is possible to close the end portions of the curtains and the like in an overlapped state. It should be noted that the front portions of the pair of traveling members only need to be able to form a space (a space in which curtains and the like overlap) between the front portions in a state of facing each other. The degree of bending or bending may be larger than the leading part of the first member, one traveling member may be linear, and the other traveling member may have a bent leading part. The pair of traveling members are usually bent or curved in such a manner that the head portions in the traveling direction can overlap each other and intersect.

  In addition, when traveling not only a pair of traveling members but also traveling members using a string, a conventional system, for example, a traveling member having a string fixing portion and the traveling member for traveling by pulling the string. A system equipped with a pulley can be used. In addition, the present invention is not limited to the string, and may be opened and closed electrically using a motor or the like, but the present invention is a shielding member such as curtains that is easily operated by an oblique or lateral traction force on the runner. This is useful for opening and closing.

  In addition, since the runner of this invention can open and close smoothly, without using the said string, the said traveling member, a string fixing member, a string fixing part, etc. are not necessarily required.

  For example, the runner of the present invention includes one or a plurality of runner main bodies having the same structure as described above, a traveling member (such as a narrow plate member) to which the runner main body is attached in the same form as described above, An attachment member for suspending a suspended object (or shielding member) from the traveling member may be provided. The traveling member may be a linearly extending member (for example, a long or short member), and the mounting member may be formed of a ring member or the like as described above. A plurality of runner bodies are attached to the running member at a predetermined interval (for example, runner bodies are attached to both side portions of a short running member). A fixing part or the like may be formed. The runner having such a configuration can be used as a leading vehicle that leads and travels along a rail when opening and closing curtains and the like.

  More specifically, in the example shown in FIG. 1, a runner including a linear traveling member in a form lacking the leading portion L and the trailing portion F (particularly, a plurality of runner bodies are provided at intervals in the longitudinal direction). Can be used as a leading vehicle.

[Rotating member]
The rotating member is not always necessary. Further, instead of the rotating member, a restricting portion such as a convex portion or a protruding line that can come into contact with the lower surface of the rail may be formed on the support portion or the suspension member at a predetermined distance from the lower surface of the rail. In addition, in the runner which is not provided with the traveling member, you may attach a rotation member to the support part of a runner. In a preferred embodiment, the runner is provided with rotating members (rollers, wheels, etc.) that can rotate on both sides of the support part and the suspension member (or the traveling member) in order to run the runner smoothly and stably. With such a rotating member, even if an oblique force is applied to the runner, the rotating member is moved to the lower surface of the rail (the lower portion of the rail opening) as the support portion tilts. Since it can contact while rotating with the lower surface of the wall or the lower regulating wall, it is possible to regulate an excessive inclination of the runner and to stably run while maintaining a predetermined posture.

[Mounting member]
As described above, the attachment member may be attached to the support portion in order to attach the suspended object (shielding member) without being attached to the suspension member (or the traveling member). Although this attachment member may attach a suspended object (shielding member) immovably, it is often attached to a support part and a suspension member (or traveling member) so that rocking is possible. The attachment member is not limited to the ring member and / or the S ring, and may be a one-touch attachment member that can attach a suspended object (shielding member) in a one-touch manner. Further, the mounting member is a swinging member that can swing relative to the support unit and the suspension member (or traveling member) between the support unit and the suspension member (or traveling member) and the suspended object (shielding member). And / or a support member, a suspension member (or a traveling member), or a rotation member that is rotatable in the circumferential direction with respect to the axial direction of the support portion. That is, instead of or together with the swing member such as the ring member, a rotation member (such as a shaft member) that is rotatable in the circumferential direction with respect to the axial direction of the support portion may be provided. In order to suspend a suspended object (shielding member), the ring member and / or the S ring, a one-touch attachment member, and the like may be attached to the rotating member (shaft member or the like).

  The one-touch type mounting member can open and close the C-shaped hook part body swingably or rotatably mounted on the support part and the suspension member (or traveling member), and the opening part of the C-shaped hook part body An opening / closing member, and the opening / closing member is a mounting member that is biased and pressed against the other portion of the hook portion body with one of the upper portion and the lower portion of the opening portion of the hook portion body as a base point. May be.

In this example, the attachment member 71 is swingably attached to the suspension member (or traveling member) 21 and has a C-shaped latching member in which one side portion is cut and an open portion 72a is formed. (Vertically long C-shaped hook body) 72 and an opening / closing member 73 attached to one end of the opening 72a of the locking member and capable of opening and closing the opening 72a. . In this example, the C-shaped latching member 72 is loosely fitted into a through-hole formed in the suspension member (or traveling member) 21 and is swingably attached. The open / close member 73 has an elongated U-shape (specifically, the other free end (open end) is shorter than the free end (open end)), and the open / close member One free end (open end) of 73 and the other free end (open end) are respectively mounted or fixed at different positions in the axial direction at the upper end portion of the open portion 72a of the C-shaped hooking member 72. . Therefore, the opening / closing member 73 has a spring action, and in a normal state, the U-shaped closed end (U-shaped curved portion) of the opening / closing member 73 has the lower end portion of the opening portion 72a of the latching member 72 outward from the inside. The open portion 72a is closed by being urged to press. In a normal state, the U-shaped curved portion of the opening / closing member 73 can be accommodated in a recess formed in the lower end portion of the opening portion 72 a of the latching member 72.

  In such an attachment member, a suspended object (or a shielding member) can be inserted from the opening 72 a using the opening / closing member 73 and can be easily attached to the latch member 72.

  As described above, the attachment member may be a suspension (or suspension) member. In particular, when a suspended object is suspended from a suspension (or suspension) member without using a traveling member (guide member), the suspension (or suspension) member may be an attachment member. In other words, the suspension (or suspension) member is C-shaped, which is swingably attached to a support portion that rotatably supports the roller shaft, and one side portion is cut away to form an open portion. And an opening / closing member attached to one end of the opening portion of the locking member and capable of opening and closing the opening portion elastically or by a spring action. May be provided.
