As will be described in detail later, when the magnetic attraction member 54 is lowered until it comes into contact with the floor G, the magnetic attraction member 54 is lifted (or lifted) by being pushed up by some means, and the magnetic attraction member 54 The ratchet teeth 56T can rise over the ratchet pawl 56P, but even if the lifting force from the magnetic attraction member 54 is released, the ratchet pawl 56P bites into the ratchet teeth 56T and lowers the magnetic attraction member 54 There is nothing to do.

  The release means 58 includes a ratchet release member 58M having a ratchet pawl 56P that is pivotally supported by a pivot pin 58P at the outer end of the frame 52. The ratchet release member 58M is opposite to the side having the ratchet pawl 56P. The ratchet pawl 56P is pressed by the spring 58S at the side portion so as to press against the ratchet teeth 56T on the magnetic attraction member 54 side. The release means 58 can release the claw 56P from the ratchet teeth 56T of the magnetic suction member 54 by pressing the ratchet release member 58P against the spring 58S, and can lower the magnetic suction member 54 by its own weight. .

  Next, an operation process when the sliding door 10 having the sliding door steady-state guide device 20 of the present invention is installed in a building will be described below with reference to FIG.

  When the sliding door 10 having the steady rest guide device 20 of the present invention is installed in a building, a plurality of floor side guide units 40 are attached at intervals to the floor G according to the running rail 16 of the sliding door. Door-side guidance units 50 are attached to both ends of the guide rail 30 on the lower surface of the door body of the sliding door 10 (see FIGS. 1 and 7). In this state, the magnetic attraction member 54 of the door side guidance unit 50 is housed in the frame 52 without protruding from the frame 52 (see FIG. 7A).

  The setting operation of the height position of the magnetic attracting member 54 of one door-side guidance unit 50 on the left side of FIG. 1 will be described. The floor-side guide unit 40 is rearward in the traveling direction (left direction) of the door body 12. When the door side guide unit 50 is in the state shown in FIG. 7A, when the upper side of the ratchet release member 58M of the release means 58 of the door side guide unit 50 is pushed in, the ratchet release member 58M is shown in FIG. B) swings clockwise to release the ratchet pawl 56P from the ratchet teeth 56T. Therefore, the magnetic attraction member 54 pivots downward by its own weight with the pivot pin 54PP as a fulcrum, and its front end is the floor. Contact G.

  In this state, when the door main body 12 (not shown in FIG. 7) travels to the left in FIG. 7, the door-side guidance unit 50 attached to the lower front end moves in the same direction. The magnetic attracting member 54 that is in contact is lifted by the guide member 42 of the floor side guide unit 40 (see FIG. 7C). The ratchet mechanism, which is the one-way movable mechanism 56, allows the ratchet teeth 56T to slide and raise the ratchet pawl 56P by lifting the magnetic attraction member 54.

  As the door main body 12 moves further leftward, the door side guidance unit 50 moves from the state of FIG. 7C to the state of FIG. 7G through FIGS. 7D, 7E, and 7F. . In the state of FIG. 7D, the magnetic attracting member 54 magnetically attracts the guide member 42 of the floor side guide unit 40 by the magnet 54M, and the guide plate 42P which is the guide member 42 is a belt of the magnetic attracting member 54. It is attracted to the lower surface of the plate 54S. Since the guide plate 42P is pivotally supported by the upper holding member 48 by the holding pin 42TP, the guide plate 42P is swung around the holding pin 42TP as a fulcrum and is entirely attracted to the lower surface of the belt plate 54S of the magnetic attraction member 54. .

  When the door body 12 further travels to the left and enters the state shown in FIG. 7E, the guide member 42 (guide plate 42P) is located above the guide rail portion 52L having the tapered groove 52G of the frame 52 of the door side guide unit 50. Therefore, the guide member 42 is relatively guided from the guide rail portion 52L to the guide rail 30 while being separated from the magnetic attracting member 54 against the magnetism by further travel of the door body 12 (FIG. 7 ( F)). Therefore, after that, the door main body 12 travels without shaking because the guide member 42 is guided along the guide rail 30.

  On the other hand, the magnetic attraction member 54 is held at the position where the lower end is lifted by the guide member 42 by the one-way movable mechanism (ratchet mechanism) in the state of FIG. The magnetic attraction member 54 moves together with the door main body 12 while maintaining the height at which the guide member 42 protrudes from the floor G even when the door main body travels (see FIG. 7G).

  In the illustrated form, the guide member 42 of the floor-side guide unit 40 protrudes from the floor G, and the magnetic attracting member 54 of the door-side guidance unit 50 is lifted from the floor G using the protruding portion of the guide member 42. However, the guide member 42 of the floor-side guide unit 40 is not necessarily required to protrude from the floor G, and may be embedded in the floor G in a state of being slightly retracted from the same surface as the floor G or the upper surface of the floor G. Good. In this case, for example, when the door main body 12 is in the position of FIG. 7B, the magnetic attraction member 54 of the door side guidance unit 50 is lifted to the door main body 12 rather than the guide member 42 of the floor side guide unit 40. An operator puts an auxiliary plate piece that lifts the magnetic attracting member 54 at the approached position on the floor G and runs the door body 12 toward the auxiliary plate piece, or the same operation is performed at the position shown in FIG. The operator inserts the auxiliary plate piece into the lower surface of the magnetic attracting member 54 and lifts it up by pushing up the magnetic attracting member 54, and then the door so that the door-side guidance unit 50 passes over the floor-side guide unit 40. The main body 12 may run. Instead of the short auxiliary plate piece, for example, the operator may push up the magnetic attracting member 54 by running the door body 12 with the strip-like push-up member obliquely along the floor.

  8 and 9 show a floor-side guide unit denoted by reference numeral 140 in a modified form of the floor-side guide unit 40 used in the steady-state guide device 20 of the embodiment of FIGS. 1 to 7. . In this form, the guide member 142 of the floor side guide unit 140 is composed of a vertical collar 142R and a plate-like head 142H provided integrally at the upper end thereof, and has a T-shaped vertical section. As shown in FIGS. 9B and 9D, the guide member 142 is held in the cylindrical holding member 146 in a state of being prevented from coming off so that the head 142H is exposed. The guide member 142 is prevented from coming off by the outer collar 142RF provided at the lower end of the vertical collar 142R and the upper inner collar 146UF of the cylindrical holding member 146.

  The base body 144 embedded in the hole GG of the floor G has a substantially circular horizontal cross section, and is attached to the inner wall surface of the hole GG by press-fitting. The base body 144 has a small outer casing 144F at the upper end, and is attached so that the outer casing 144F is placed on the upper surface of the floor G.

  The base body 144 has a holding hole 144H that is eccentric from the center thereof, and the cylindrical holding member 146 and the guide member 142 held therein are held in the eccentric holding hole 144H in a state of being prevented from coming off. . The cylindrical holding member 146 is prevented from coming off by the lower end outer flange 146LF and the upper end inner flange 144UF of the eccentric holding hole 144H (see FIG. 9C). The head 142H of the guide member 142 is exposed from the upper surface of the base body 144.

  The base body 144 has a C-shaped upper plate 144T attached to the upper surface of the base body 144 so as to surround the head 142H of the guide member 142 exposed on the upper surface thereof. As can be seen from FIG. 9, the guide member 142 and the upper attachment plate 144 </ b> T have a peripheral edge that rises with a roundness in order to facilitate the lifting of the magnetic attraction member 54 of the door-side guidance unit 50. 9B and 9D, reference numeral 144LC denotes a lower lid that closes the eccentric holding hole 144H of the base body 144.

  If the upper support plate 144T is C-shaped, there is a concave portion that opens laterally. Therefore, as shown in FIG. 9B, the guide member 142 is lifted to remove dust accumulated between the guide member 142 and the base body 144. This is advantageous because it can be easily removed by, for example.

  Also in this modified embodiment, as shown in FIGS. 8A to 8G, the floor G is lifted by the releasing means 58 from the raised position where the magnetic attraction member 54 of FIG. The magnetic attraction member 54 is then lifted by the floor-side guide member 142 or the upper support plate 144T as the door body 12 travels, and is movable in one direction (see FIG. 8B). While maintaining the lifted state by the ratchet mechanism 56 (see FIG. 8C), the guide member 142 is sucked and guided to the guide rail 30 via the guide rail portion 52L (FIGS. 8D and 8E). (See (F)). In this modified embodiment, the head 142H of the guide member 142 does not swing as in the previous embodiment, so the head 142H of the guide member 142 is partially in contact with the magnetic attraction member 54. It will be adsorbed (see FIGS. 8D to 8F). In this guide unit 140, since the guide member 142 is eccentric with respect to the circular base body 144, the position of the guide member 142 relative to the door body 12 is set by press-fitting the base body 144 into the hole GG at an appropriate angular position. Can be easily performed.

  In the illustrated form, the guide rail portion 52L of the frame 52 has a tapered groove 52G. However, if there is a portion into which the guide member 42 or 142 enters, the guide rail portion 42L may not be a tapered groove, and the length of the frame 52 is small. If the guide member 42 or 142 that has entered the frame 52 is sucked and can be immediately guided from the frame 52 to the guide rail 30, the guide rail portion 52L may be omitted.

  According to the present invention, as described above, the magnetic attracting member of the door side guiding unit that attracts the guiding member of the floor side guiding unit and guides it to the guide rail has a height that effectively acts on the guiding member magnetically. Since it is possible to easily carry out the work of lifting from the floor surface within the range, it can be utilized beneficially in the industry.
