Description

  The present invention relates to a belt device with a notation.

  In elevator maintenance and repair work, maintenance personnel may go in and out of pits and hoistways, so the doors of the halls where the cab is not located may be opened. At that time, measures were taken to prevent people from accidentally entering the hoistway from the entrance / exit of the hall without a cab.

  Conventionally, as the above-mentioned countermeasure, for example, as disclosed in Patent Document 1, a safety fence made of a pole, a partition curtain, or the like is installed in front of a landing doorway with an open door, and the elevator is under maintenance repair. There is an aspect that alerts the person to prevent the person from entering by mistake.

  As another example, as disclosed in Patent Document 2, it is installed so as to cross the strip in a three-way frame around the entrance so as to close the entrance / exit, and the elevator is still under maintenance repair. There is also an aspect that alerts and prevents people from entering by mistake. Further, belt reels are provided at both ends in the longitudinal direction of the belt-like body, and it has been intended to be able to deal with three-way frames (land entrances / exits) having various widths through winding and unwinding of the belt-like body.

  Embodiments of a belt device with notation according to the present invention will be described below with reference to the accompanying drawings. In the drawings, the same reference numerals indicate the same or corresponding parts. Further, the description of directions in the specification and claims of the present application is based on the paper surface (at-use posture) in FIG.

Embodiment 1 FIG.
FIG. 1 is a diagram showing the front of the belt device with notation according to the first embodiment. FIG. 2 is a diagram showing the plane, and FIG. 3 is a diagram showing the back surface of the vicinity of the belt adjuster described later. The belt device 1 with notation includes a belt 3 and a pair of magnet catches 5. Each of the pair of magnet catches 5 is provided at a corresponding end portion in the longitudinal direction of the belt 3 and is generally formed in a block shape. Each of the magnet catches 5 has a flat magnetic force attracting surface 5 a on the surface opposite to the side connected to the belt 3. The pair of magnet catches 5 abuts and attracts the magnetic force attracting surface 5a to, for example, a magnetic part in a three-way frame around the elevator entrance and exit, for example. (Per eye level).

  The belt 3 has an elastic belt portion 7 and an inelastic belt portion 9. The elastic belt portion 7 is made of a stretchable material that generates tension between the pair of magnet catches 5 so as not to loosen the entire belt 3. For example, the elastic belt portion 7 is made of a rubber sheet or a rubber belt. ing. However, the length is not limited to this, and any length may be used as long as the length increases when an external force is applied, but the length is restored to the original length when the external force is removed.

  The inelastic belt portion 9 is connected to the elastic belt portion 7 in the belt length direction via a folding member 11 described later. The inelastic belt portion 9 has a notation region 13 on at least one surface thereof, in the present embodiment, on the front surface. The notation area 13 is an example to the last, but is an area where a message such as “Please do not approach while working” is described. It is not always necessary to use letters, but if you can expect the effect that the elevator is under maintenance repair and prevent people from entering accidentally, you can use marks, symbols, and alert colors (for example, Any notation such as black / orange alternate color or red) may be used.

  The inelastic belt portion 9 is provided with a belt adjuster 15 that changes the length of the inelastic belt portion 9. Further, the inelastic belt portion 9 is configured by folding a belt-like body that hardly expands and contracts between the belt adjuster 15 and the folding member 11. The belt-like body is not particularly limited as long as it is flexible and can be folded back, but hardly stretches, but a specific example includes a resin fiber sheet or a resin fiber belt. ing.

  FIG. 4 is a view showing the front of the belt adjuster, and FIG. 5 is a view showing a manner of folding the belt-like body. First, as shown in FIG. 4, the belt adjuster 15 includes a B ring in which the letter “B” is arranged horizontally. The B ring includes a central shaft 17 and a first outer shaft 19 and a second outer shaft 21 on both outer sides thereof. Further, a first insertion hole 23 and a second insertion hole 25 are provided between the central shaft 17 and the first outer shaft 19 and between the central shaft 17 and the second outer shaft 21.

  The folding | returning aspect of the strip | belt-shaped body of the inelastic belt part 9 is demonstrated in order of the direction from the one end to the other end. As can be understood from FIGS. 2 and 5, one end 27 of the belt-like body of the inelastic belt portion 9 is attached to the central shaft 17 of the B ring, and extends therefrom toward the folding member 11. After being folded back, it extended back to the B ring, passed through the first insertion hole 23 from the back side of the B ring to the front side, and further passed through the second insertion hole 25 from the front side to the back side. Thereafter, the other end 29 of the belt-like body is connected to one of the pair of magnet catches 5.

  2 and 5, one end of the inelastic belt portion 9 is connected to the folding member 11, and the other end of the inelastic belt portion 9 is connected to the pair of magnet catches 5. One end of the elastic belt portion 7 is connected to the folding member 11, and the other end of the elastic belt portion 7 is connected to the other of the pair of magnet catches 5.

Moreover, the belt apparatus 1 with a description satisfy | fills the following relationships.
That is, the mass of the belt device 1 with notation is W, the elastic force (the tension to be generated) of the elastic belt portion 7 is E, the attractive magnetic force of each magnet catch 5 is M, and the brake force of the belt adjuster 15 is S. When, at least,
(W / 2) <E <M, E <S
It is configured to satisfy. At this time, it is more preferable that M ≦ S.
As a result, tension is generated so that the belt 3 is slackened and the message in the notation area 13 cannot be read, and the belt adjuster 15 loses its tension and belt weight over time, and the belt 3 is slackened. The magnet catch 5 is designed so as not to come off due to tension or belt weight.

  In the belt device with the notation configured as described above, first, the magnet catches 5 respectively corresponding to the left and right side walls of the three-way frame of the elevator hall with the belt 3 slackened to a sufficient length. To adsorb. The length of the inelastic belt 9 is gradually reduced by sliding the belt adjuster 15 in the longitudinal direction of the inelastic belt 9 in the belt 3 that is slack with respect to the width of the left and right side walls of the three-way frame. Finally, the belt adjuster 15 is slid until the belt 3 is tightly tensioned by the elastic force of the elastic belt portion 7.

  Thus, according to the belt device with notation according to the first embodiment, since the belt-like thing is only held at both ends, it can be configured smaller and lighter than the conventional safety fence described above, and installed.・ Removal / moving work is easy and workability is extremely good. In addition, since it is not necessary to use a belt reel like the conventional device described above, it is possible to avoid a high cost while being able to cope with various installation widths. There is almost no risk of such damage. In addition, the belt is intentionally clearly divided into a part that has a notation area and does not expand and contract and a part that does not have a notation area and generates tension due to expansion and contraction. The message will not be visible from the front, and the message text will not be able to be read because it is stretched, smoldered or faded. That is, the belt 3 of this device can be expanded and contracted in order to achieve the two points that it can extend to various installation widths and obtain tension so as not to loosen. The function of is not going to drop. Furthermore, the installation of the belt device with the notation can be completed easily by only one maintenance person because it is only necessary to first attach the magnetic catches at both ends and then slide the belt adjuster. No skill is required. In particular, the belt may be loosened while the pair of magnet catches are attached to objects that are separated from each other, that is, it is not necessary to apply a tension to maintenance personnel while attaching the pair of magnet catches. This also helps that the installation of the belt device with the notation can be completed easily by only one maintenance staff.

Embodiment 2. FIG.
In the first embodiment, the case where the fixing destination is a magnetic part has been described as an example. However, the present invention is not limited to this, and the fixing destination can also be implemented when the fixing destination is a nonmagnetic part. The second embodiment is an example. FIG. 6 is a diagram of the same mode as FIG. 2 regarding the second embodiment.

  The belt device with notation 101 according to the second embodiment is obtained by further attaching a suction cup metal base 151 to the magnetic force attracting surface 5a of each magnet catch 5 in the belt device with notation 1 according to the first embodiment. Therefore, the configuration other than the pair of suction cup metal bases 151 is the same as that of the first embodiment. 7 is a view showing a state in which the suction cup metal base is viewed from the belt extending direction, and FIGS. 8 and 9 are views showing the plane and the back of the suction cup metal base in FIG. 7, respectively.

  As shown in FIGS. 7 to 9, each of the suction cup metal bases 151 has one or more (two in this example) suction cups 153 and a first adsorption metal surface 155. Each of the pair of suction cup metal bases 151 is attracted to the corresponding magnet catch 5 by a magnetic force on the first adsorption metal surface 155 to constitute both ends of the belt device 101 with the notation.

  The two suction cups 153 are attached to the opposite side of the first suction metal surface 155 in the corresponding suction cup metal base 151. Further, the two suction cups 153 are arranged so as to be lined up and down when the belt device with notation is used (attached). The suction cup 153 is attached by fastening means such as bolts, and the fastening means is prepared for each suction cup 153. Corresponding to the two suction cups 153, two heads 157 of fastening means protrude from the first adsorption metal surface 155. The two heads 157 of the two fastening means are also positioned so as to be lined up and down when the belt device with notation is used. Each magnet catch 5 is attracted to the first attracting metal surface 155 so as to be sandwiched between the two heads 157.

  A pair of first guard pieces 159 and 161 are provided on each of the pair of suction cup metal bases 151. The pair of first guard pieces 159 and 161 rise from the first adsorbing metal surface 155 and are spaced apart from each other so as to be lined up in the lateral direction when the belt device with notation is used. To describe a more specific example, the pair of first guard pieces 159 and 161 are formed so as to be orthogonal to the first adsorption metal surface 155 and extend in parallel to each other. Each magnet catch 5 is attracted to the first attracting metal surface 155 so as to be sandwiched between the pair of first guard pieces 159 and 161.

  One of the pair of first guard pieces 159 and 161 rises higher than the other, that is, is divided into a high guard piece 159 and a low guard piece 161. The high guard piece 159 has a second adsorption metal surface 163 on the side facing the low guard piece 161.

  Even with the belt device with notation 101 according to the second embodiment configured as described above, as in the first embodiment, various work can be performed while improving workability and avoiding cost increases. Can accommodate width. In addition, in the second embodiment, both ends of the belt can be supported via a pair of suction cup metal bases, and can also be implemented when the fixing destination is a nonmagnetic portion. In addition, it is only necessary to attach a pair of suction cup metal bases to the pair of magnet catches, and it is also necessary to attach the suction metal surfaces of the pair of suction cup metal bases to the pair of magnet catches. It is not necessary to recreate the structure of the belt device with a notation when the tip is a magnetic part, and the non-magnetic part can be implemented simply by adding a simple magnetic force adsorption operation, and the workability is good.

  Also, the magnet catch is restrained from being displaced in the vertical direction during use by the two heads of the fastening means for fixing the suction cups and coming off from the suction cup metal base. It is suppressed that it slip | deviates to a direction and remove | deviates from a suction cup metal stand. In particular, when the magnet catch is used, the vertical displacement can use the fastening means for fixing the suction cup in the first place, so that there is an advantage that the number of parts is reduced and the structural complexity and cost increase are suppressed.

  Further, the magnet catch can be adsorbed on either the first adsorption metal surface or the second adsorption metal surface as necessary. Therefore, for example, as shown in FIG. 10, even in a property in which the fixing destination of the belt device with notation can be secured only on the surface along the elevator landing door, the design change, rework, addition of auxiliary parts, etc. It is possible to cope with this by simply changing the direction of the pair of suction cup metal bases with respect to the pair of magnet catches. Further, at this time, since one of the pair of first guard pieces is a low guard piece, even if the direction of the pair of suction cup metal bases is changed by 90 degrees, the belt does not interfere with the belt.

Embodiment 3 FIG.
The third embodiment is a further modification of the suction cup metal base in the second embodiment, and is configured in the same manner as in the second embodiment except for the parts described below. FIG. 11 is a diagram showing a plane of the suction cup metal base relating to the third embodiment. The pair of suction cup metal bases 251 in the third embodiment has a second guard piece 265 rising from the second adsorption metal surface 163 at the tip of the high guard piece 159. Regarding the relationship with the first adsorption metal surface 155, the second guard pieces 265 are provided so as to be spaced apart from each other so as to be arranged in the lateral direction when the belt device with a notation is used. More specifically, the second guard piece 265 and the first adsorbing metal surface 155 are formed so as to be orthogonal to the second adsorbing metal surface 163 and extend parallel to each other. Further, the length of the second guard piece 265 is set to be much shorter than the length of the first adsorption metal surface 155. That is, the relationship between the second guard piece 265, the second adsorption metal surface 163, and the first adsorption metal surface 155 is the same as the relationship between the low guard piece 161, the first adsorption metal surface 155, and the high guard piece 159.

  The magnet catch 5 is either a first adsorption metal surface 155 between the pair of first guard pieces 159 and 161 or a second adsorption metal surface 163 between the second guard piece 265 and the first adsorption metal surface 155. Can be attached to either. When the magnet catch 5 is attached to the first adsorption metal surface 155, the magnet catch 5 is adsorbed to the first adsorption metal surface 155 so as to be sandwiched between the pair of first guard pieces 159 and 161. In addition, the two heads 157 and the pair of first guard pieces 159 and 161 prevent vertical displacement and lateral displacement. Further, when the magnet catch 5 is attached to the second adsorption metal surface 163, the magnet catch 5 is sandwiched between the first adsorption metal surface 155 and the second guard piece 265 so as to be attached to the second adsorption metal surface 163. The two heads 157, the first adsorbing metal surface 155, and the second guard piece 265 are prevented from being displaced in the vertical direction and in the lateral direction. Further, the second guard piece 265 and the low guard piece 161 do not interfere with the belt 3 regardless of whether the first adsorbing metal surface 155 or the second adsorbing metal surface 163 is attached.

  Also with the belt device with notation according to the third embodiment configured as described above, as in the first embodiment, while improving workability and avoiding cost increases, various installation widths are also possible. In addition, the same advantages as those of the second embodiment are also obtained. In addition, in the third embodiment, both the vertical and horizontal deviations are the same regardless of whether the magnet catch is attached to the first adsorption metal surface or the second adsorption metal surface. It can be suppressed.

  Although the contents of the present invention have been specifically described with reference to the preferred embodiments, various modifications can be made by those skilled in the art based on the basic technical idea and teachings of the present invention. It is self-explanatory.
