Curtain rail structure

Abstract

To solve a problem of a conventional curtain rail structure which is not suitable for continuously moving a plurality of curtains due to its structure in which a single curtain is dedicated to move, using a specific curtain rail, from a main rail to a selected sub rail and return the same curtain from the sub rail to the main rail, and also in which the switching position is not clearly visible when switching the rail due to the specific shape of the curtail rail which restricts the available place.SOLUTION: A structure allows the use of a plurality of curtains by allowing a release of fixing of a switch stopper only when the top curtain runner of each of the curtains passes through a switching position. Depending on the used location and the curtain design, the type of the curtain rail can be changed by the curtain rail attached to a frame of the basis. Also, when the top curtain runner reaches the rail switching position, a magnetic load is applied to the top curtain runner to prohibit advancement during the movement at a certain speed or less.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to a curtain rail structure suitable for hanging curtains used as partitions between hospital beds, store sections, and changing rooms and nursing rooms. [Background technology]

[0002] Prior art inventions have disclosed curtain rail structures in which a single main rail is connected to one of multiple sub-rails via a swinging rail that serves as a branch, and multiple curtain runners for one curtain run within the curtain rail (see Patent Documents 1 and 2). These curtain rail structures include a main rail on which the curtain runners run, a sub-rail, a swinging rail, and a connecting plate that connects the rails together, and the connecting plate has a magnetically attached (see Patent Document 1) or magnetically repulsive holding mechanism that pushes the swinging rail to a desired position, with the swinging axis as the base point and the swinging hole restricting the angle of swing. A branch is provided that allows the main rail to be connected to multiple sub-rails.

[0003] Both of these curtain rail structures use the same type of curtain rail and can switch between multiple sub-rail positions using a swing hole that regulates the swing rail's movable fulcrum and range of movement. The magnetically attached curtain rail structure (see Patent Document 1) holds the swing rail in the desired position. After the swing rail selects the sub-rail on the curtain's destination side, the swing rail is fixed in place by the magnetic attraction of the connecting plate's magnet and the swing rail's magnet in the selected direction. When the curtain runner passes through the locking member, the leading protrusion of the curtain runner presses against the protrusion of the locking member, causing the switching stopper to protrude into the sub-rail. After the swing rail is fixed to the sub-rail, the leading protrusion of the curtain runner pushes up the protrusion of the locking member and enters the sub-rail. Furthermore, as the curtain runner moves from the sub-rail to the swing rail, the leading protrusion of the curtain runner presses against the protrusion of the locking member, retracting the switching stopper into the swing rail, after which the leading protrusion of the curtain runner pushes up the protrusion of the locking member and enters the swing rail. The curtain rail structure of the magnetic repulsion holding mechanism (see Patent Document 2) that pushes the oscillating rail to the desired position selects the secondary rail on the curtain's destination side with the oscillating rail, and then fixes the oscillating rail by pressing it in the selected direction using the repulsive force of the magnets in the connecting plate and the magnets in the oscillating rail. When the curtain runner passes through the locking member, the protrusion at the front of the curtain runner presses against the protrusion on the protruding side of the locking member, causing the switching stopper to protrude toward the connecting plate. After the oscillating rail and connecting plate are fixed, the curtain runner enters the secondary rail and releases the lock. Furthermore, as the curtain runner moves from the secondary rail into the oscillating rail, the protrusion at the front of the curtain runner presses against the protrusion on the locking member, retracting the switching stopper into the oscillating rail and entering the oscillating rail, releasing the lock.

[0004] The curtain rail structure with a magnetic attachment type (see Patent Document 1) that holds the oscillating rail in the desired position and the curtain rail structure with a magnetic repulsion type holding mechanism (see Patent Document 2) that pushes the oscillating rail to the desired position are basically based on the premise that a set of curtains will move back and forth and the curtain rail structure will be used by switching. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-279614 [Patent Document 2] W02013 / 014815 publication Summary of the Invention [Problem to be solved by the invention]

[0006] In a magnetic curtain rail structure (see Patent Document 1) that holds a swinging rail in a desired position, after the swinging rail selects the secondary rail on the curtain's destination side, the projection at the front of the curtain runner presses against the projection on the locking member as the curtain runner passes through the locking member, causing the switching stopper to protrude onto the secondary rail, and after the curtain runner is fixed to the secondary rail, the projection at the front of the curtain runner pushes up the projection on the locking member and enters the secondary rail. If the curtain runner enters at a high speed during this passage, the projection on the locking member will not be able to apply enough pressure to protrude and fix the switching stopper onto the secondary rail, and the projection at the front of the curtain runner will push up the projection on the locking member and enter the secondary rail, which could result in incomplete locking or release.

[0007] The curtain rail structure of the magnetic repulsion type holding mechanism (see Patent Document 2) that pushes the oscillating rail to the desired position selects the secondary rail on the curtain's destination side on the oscillating rail, and when the curtain runner passes through the locking member, the protrusion at the front of the curtain runner presses against the protrusion on the protruding side of the locking member, causing the switching stopper to protrude into the fixing hole in the connecting plate, and after the oscillating rail and connecting plate are fixed, the curtain runner enters the secondary rail. The locking member protrudes the switching stopper only when it moves from the main rail to the secondary rail, and when the front end of the curtain runner presses the protrusion on the protruding side of the locking member to protrude and fix the switching stopper, and then the connection destination is reselected to a different secondary rail, the protrusion at the front of the curtain runner moves toward the main rail, presses the protrusion on the retracting side of the locking member, and retracts the switching stopper, and the front end of the curtain runner is in a position where it does not come into contact with the protrusion on the locking member of the oscillating rail, changing the connection destination of the oscillating rail.As it is not clear whether the front end of the curtain runner is pressing the protrusion on the locking member, and it is not clear at what position on the oscillating rail the connection destination can be switched, it may not be possible to switch the oscillating rail.

[0008] In these curtain rail structures (see Patent Documents 1 and 2), only the leading edge of the curtain runner of the first curtain presses the protrusion of the locking member to fix the oscillating rail, so the curtain can only be used alone, and is not suitable for using multiple curtains, which require the oscillating rail to be released once in order to select the secondary rail again. Also, the oscillating rail needs to be switched before passing through the locking member, but because the position of the locking member of the oscillating rail cannot be clearly seen by the person moving the curtain, it may not be possible to switch depending on the position at which the oscillating rail is switched.

[0009] The curtain rail structure described in the previous section has a double structure with an upper and lower part, and is not suitable for curtain rails of any other shape.

[0010] The first object of the present invention is to provide a curtain rail structure that allows multiple curtains to be used consecutively and that enables the swinging rail to be switched for each passage of multiple curtains. The second object of the present invention is to provide a curtain rail structure that eliminates the directionality of the locking and unlocking directions as the curtain advances and the locking member passes. The third object of the present invention is to provide a curtain rail structure that uses a rail mount and connecting plate to mount the curtain rail to switch the curtain's direction of advance, lock and unlock with the locking member, and assist in selectively fixing the swinging rail mount. The fourth object of the present invention is to provide a curtain rail structure that provides a series of functions using the rail mount and connecting plate defined in the third object, allowing the type of curtain rail to be easily changed simply by connecting the curtain rail to the rail mount. [Means for solving the problem]

[0011] The first solution of the present invention is a structure in which a locking member on the oscillating rail, which is operated by the movement of the curtain, restricts switching when the curtain moves from the main rail side to the secondary rail side, and releases the restriction on switching when the curtain moves from the secondary rail side to the main rail side, and makes it possible to restrict and release switching of the oscillating rail by having the leading curtain runner in a specified position regardless of the direction of curtain movement, thereby changing a structure that can only switch the oscillating rail with a single curtain to a structure that can switch the oscillating rail when multiple curtains pass by.

[0012] The second solution of the present invention is to change the structure in which the oscillating rail can be switched by swinging the oscillating rail using a curtain, but the position of the oscillating rail that can be switched using this curtain is not known, to a structure in which the position where switching is possible is known.

[0013] A third solution of the present invention is a structure in which the curtain rail used in the curtain rail mechanism has a specified shape, but the shape of the curtain rail can be changed as desired. [Effects of the Invention]

[0014] With conventional curtain rail structures, to change the path of a single curtain, the lead of the curtain runner attached to the curtain must be moved from the oscillating rail toward the desired sub-rail before passing the locking member inside the oscillating rail. After the locking member inside the oscillating rail is moved from the oscillating rail to the sub-rail, the curtain runner is fixed to the connecting plate by a switching stopper and remains fixed until the lead of the curtain runner attached to the curtain moves through the locking member inside the oscillating rail from the sub-rail to the oscillating rail, resulting in a locking member structure that cannot be used for multiple curtains. Therefore, with the structure of the first solution of the present invention, the switching stopper that protrudes into the connecting plate is retracted only when the leading magnetic curtain runner is located at the locking member position inside the oscillating rail, making it possible to select the sub-rail for the oscillating rail. By attaching a leading magnetic curtain runner to the leads of multiple curtains, each of the multiple curtains can select and move to the desired sub-rail to change their path each time the leading magnetic curtain runner is located at the locking member position of the oscillating rail, making it possible to use not only a single curtain but also multiple curtains.

[0015] In conventional curtain rail structures, in order to switch the swinging rail by pushing or pulling the curtain, it is necessary to find the range where the swinging rail, which uses the swinging support pin as a fulcrum, switches by pushing or pulling the curtain.However, with the structure of the second solution of the present invention, the curtain runner fall-off prevention part attached to the swinging rail base serves as a visual guide position, and a curtain runner with a built-in magnet is used at the front of the curtain.By using the magnet built into the locking member to repel from the front and back and to supplement the position by attraction at the stop position, it is possible to guide the swinging rail to a position where it can be easily switched by pushing or pulling the curtain.In addition, if there is a certain speed, it is possible to operate without impeding the movement of the curtain.

[0016] Conventional curtain rail structures require the use of designated curtain rails for designated purposes, and are structured so that the type of curtain rail cannot be changed. However, the structure of the third solution of the present invention provides a stand for the main rail, a stand for the sub-rail, and a stand for the oscillating rail, and these stands are the mechanism responsible for connecting and operating the connecting plates. This means that simply by connecting each stand to each rail, the curtain can be moved from the main rail to the selected sub-rail, and the switching function can be used simply by attaching various curtain rails to the stands.

DETAILED DESCRIPTION OF THE INVENTION

[0018] An embodiment of the present invention will be described with reference to the drawings. As shown in Fig. 1(a), a single main rail 2a is connected to multiple secondary rails 3a, 3b via a swing rail 4a. As shown in Fig. 1(b), curtain runners 6, 7 run on selected secondary rails 3a, 3b by operating the swing rail 4a from the main rail 2a. A curtain runner fall-off prevention unit 41 is attached to the secondary rail side of the swing rail mount 4 to prevent the curtain runners from falling off unselected secondary rails due to reverse running. The rails 2a, 3a, 3b, and 4a on which the curtain runners run are each selected based on the application. The main rail 2a is attached to the main rail mount 2, the swing rail 4a is attached to the swing rail mount 4, the secondary rails 3a, 3b are attached to the secondary rail mount 3, and the main rail mount 2, secondary rail mount 3, and swing rail mount 4 are attached to a connecting plate 1. Furthermore, in the description of this embodiment, two sub-rails are used, but three or more sub-rails may be used.

[0019] As shown in Figure 6, the curtain runners 6, 7 travel along the main rail 2a, swing rail 4a, and select either the sub-rail 3a or 3b, and then travel along the reverse route when returning. However, if there is too much space at the connection surfaces between these rails, the contact load between the curtain runners 6, 7 and the various rails increases, and the curtain runners 6, 7 deteriorate quickly. Therefore, the track most frequently used for the curtain is the main rail 2a and the straight line of the straight line of the sub-rail 3a. This reduces the load on the curtain runners 6, 7 used for travel, and selects the sub-rail 3b, which is not straight and uses the swing rail support pin 1c as the base point, as shown in Figure 2(a). In this case, in order to reduce the burden on the curtain runners 6, 7 passing through the portion connecting the main rail 2a to the oscillating rail 4a, the end of the oscillating rail 4a on the main rail 2a side is cut to match the angle at which it is driven, with the oscillating rail support pin 1c as the base point, so that the space at the rail connection surface does not open up too much in the selected direction, as shown in Figure 2(b).Also, as shown in Figure 2(c), the end of the oscillating rail 3b on the oscillating rail 4a side is cut to match the angle at which it is driven, so that the space at the rail connection surface between the selected secondary rail 3b and the selected secondary rail 3b does not open up too much, thereby reducing the burden on the curtain runners 6, 7 when they move across the rail connection surface.

[0020] As shown in Figures 3 and 4, the basic frame is made up of a connecting plate 1, a connecting plate spacer 12, and a connecting plate protector 11, and as shown in Figures 3(a) and 3(c), the frame and the main rail 2a, which is a single rail, are sandwiched and fixed with a fitting 2aa that attaches the main rail 2a and an adjustment plate 2c for adjusting the space to reduce the operating load during swing, and the main rail frame 2; and as shown in Figures 3(b) and 3(d), the frame and secondary rails 3a, 3b, which are multiple rails that can be branched off at will, are sandwiched and fixed with a fitting 3aa that attaches the secondary rail 3a and a fitting 3ba that attaches the secondary rail 3b and an adjustment plate 3c for adjusting the space to reduce the operating load during swing, and the secondary rail frame 3 to be attached.

[0021] As shown in Figure 4(a), the base is made up of a connecting plate 1, connecting plate spacer 12, and connecting plate protector 11, and a swing rail base 4, which is fitted with a swing rail 4a, a rail that can be selected and driven at will, is connected to the connecting plate 1 by a swing support pin 1c and a swing drive pin 1da that drives together with a swing magnet 1d. The connecting plate 1 and swing rail base 4 are connected by the swing support pin 1c, which serves as the fulcrum for swing movement as shown in Figure 4(b), and a bearing drive unit 1ca is fixed to the swing rail base 4 at the connecting part to allow the swing support pin 1c to operate smoothly, and a support adjustment spacer 1cb is sandwiched and fixed in place to adjust the space and reduce the operating load during swing. The swing drive pin 1da, which moves within the swing hole 1a of the connecting plate 1 in Figure 4(c), uses the repulsive force of a magnet to fix the position after the swing rail is put into operation, so the swing magnet 1d and the drive adjustment spacer 1db, which adjusts the space to reduce the operating load during swing, are sandwiched between the swing rail base 4 and fixed with a fastener 1dc. A base magnet 1e is attached to the connecting plate 1 at the center of the magnetic repulsion, and when the swing magnet 1d moves within the swing hole 1a and passes the midpoint of the magnetic repulsion of the base magnet 1e, the swing magnet 1d is pressed to the stop position by the magnetic repulsion and fixed in place (see Figures 1(a) and 2(a)).

[0022] To fix the swing rail with the locking member 5 in Figure 4(d), after selecting any sub-rail on the swing rail base 4, the locking member switching stopper protruding magnet 5c and the swing rail switching stopper protruding magnet 5ca are pushed down by repelling them with the locking member switching stopper shaft 5b as the base point, as shown in Figure 5(a), and the switching stopper 5a is pushed up to protrude and fix it to the fixing hole 1b of the connecting plate 1. This fixed state is maintained as long as the leading curtain runner 6 is not in the unlocked position.

[0023] Controlling the locking member 5 requires runners to hang and move the curtain 8, as shown in Figure 6, and one curtain 8 is hung by a combination of a leading curtain runner 6 and multiple curtain runners 7 (see Figure 7), which run along each rail. The leading curtain runner 6 has a runner magnet 6a fixed by a stopper retraction magnet fixing portion 6b, and when the runner magnet 6a is positioned directly below the switching stopper retraction magnet 5d of the locking member 5, as shown in Figure 5(b), it pulls down the switching stopper 5a using the locking member switching stopper shaft 5b as the base point due to magnetic attraction, and the switching stopper 5a no longer protrudes, thereby releasing the fixation.

[0024] In order for the leading curtain runner 6 to stop at the unlocked position, a curtain runner stop magnet 5e is installed inside the sub-rail mount 3, which prevents the leading curtain runner 6 from moving forward by magnetic repulsion with the runner magnet 6a, and assists in stopping the leading curtain runner 6 at the switching position by magnetic attraction between the switching stopper retraction magnet 5d and the runner magnet 6a. Also, if there is no need to stop, the curtain 8 is moved at high speed.

[0025] The purpose of this curtain rail structure is to send curtains 8 from main rail 2a to selected sub-rails 3a and 3b. As shown in Figure 8, multiple curtains 8 are gathered in one location, and curtain rail branch units 10 are placed at each branch, connecting swing rail 4a to main rail 2a and sub-rails 3a and 3b, allowing any curtain 8 to be moved to any location. [Industrial Applicability]

[0026] Without the need for major renovation work, existing curtain rails can be changed from a configuration with multiple separate curtain rails to one with multiple routes, and curtains that were previously used individually can now be used as multiple curtains while considering their destination. As a result, curtains can be collected and stored in one place, so it is expected to be used in a wide range of fields, not only for expanding and dividing the area around a bed, but also for dividing multiple rooms or places where pinpoint partitioning is required, taking advantage of the advantage of being able to use curtains only when and where needed.

3. 10. The curtain rail structure of claim 2, wherein the locking mechanism in the swaying rail mount is configured such that when the switching guide magnet attached to the front of the curtain runner passing through the swaying rail attached to the swaying rail mount reaches the position of the locking mechanism, the curtain runner stopping magnet attached to the sub-rail mount guides the curtain runner to a stopping position, attracting the switching magnet of the locking mechanism to the curtain runner side.
