Description

  The present invention relates to a direction display of a long body such as a blind operation string.

As the blind operation string, an annularly continuous string is used.
FIG. 1 shows a conventional annular blind operating string.
The blind operating string 1 is formed in an annular shape, the blind operating string upper part 2 is coupled to the operating part of the blind, and the blind operating string lower part 3 is free to be operated by the user.

In order to open and close the blinds, the blind operation string 1 must be pulled, but if the direction is pulled in the O (Open) direction as shown by the arrow in FIG. 1, it opens, and in the C (Close) direction. Even if it closes by pulling, the user has no clue about the operation direction. Therefore, the user pulls on both the O side and the C side to determine the necessary direction.
It is very inconvenient for the user to perform such an operation.

  In addition, when using various cables for electrical connection, if the cable is short, the connection direction of the cable can be easily confirmed, but if it is long, the end of which direction of the cable is desired. Cannot determine if it is connected to the device.

  Furthermore, although the rotary motion body can be regarded as a continuous body having an infinite length, it is not always easy to know the necessary rotation direction when performing some operation by rotating the annular body.

  Japanese Laid-Open Patent Publication No. 2000-2066 discloses a louver operating string 4 configured as shown in FIG. The operation string 4 is formed with a first mark portion 5, a second mark portion 6, and no-mark portions 7, 8, 9, and 10 in this order.

The first mark portion 5 and the second mark 6 are short, and the no-mark portion 7 is long.
Further, the first mark portion 5 and the second mark portion 6 are formed adjacent to each other, and the space between the second mark portion 6 and the next first mark portion 5 is formed with a non-marked portion 7 to 10 interposed therebetween. Has been.

  For example, the first mark portion 5 and the second mark portion 6 are colored white for the first mark portion 5 indicating the direction to be drawn to open the blind, and the second mark portion 6 indicating the direction to be drawn for closing is black. Is colored. The non-marked portions 7 to 10 are colored in the original color of the operation string 4, for example, gray.

  In order to operate the blind operation string 4 and to direct the louver in the direction in which light enters, the gray no-mark part 9 adjacent to the white first mark part 5 indicating the direction to be drawn to make it brighter is moved in the O direction. Pull on. In order to turn to the direction where light does not enter, the gray mark-free portion 7 adjacent to the black second mark portion 6 indicating the direction to be drawn in order to darken is drawn in the C direction.

  Since the first mark portion 5 and the second mark 6 have a certain length in the operation string 4, the presence of the operation string 4 that should not be conspicuous is conspicuous.

  In addition, it is difficult to later provide the first mark portion 5 and the second mark 6 on the existing operating cord 4 of the blind, and the operating cord 4 having the first mark portion 5 and the second mark 6 is provided. Replacing the operating string is a laborious operation.

  As a means for displaying the operating direction of the blind operation string, an auxiliary tool that can use the blind operation string 1 as it is and know the operation direction is disclosed in Japanese Utility Model Publication No. 61-11894.

  This auxiliary tool 11 shown in FIG. 3 is a tubular body loosely fitted to the blind operation string 1, and is composed of, for example, a first mark portion 12 colored yellow and a second mark portion 13 colored black. ing.

Since the auxiliary tool 11 is loosely fitted to the blind operation string 1, it is always at the lower end of the blind operation string 1.
To open the blind by operating the blind operating string 1 to which this auxiliary tool is attached, pull the string 14 on the first mark portion 12 side colored yellow indicating the direction to be pulled to open, and close it to close it. Therefore, the string 15 on the second mark portion 13 side colored in black indicating the direction to be drawn is drawn.

  Attaching the auxiliary tool 11 to the existing blind operation string 4 later is a time-consuming operation.

JP 2000-2066 A Published Utility Model Publication Sho 61-11894

  An object of the present invention is to provide an operation string whose presence does not stand out even though the operation direction can be easily known.

  It is another object of the present invention to provide an auxiliary tool for an operation string that can provide an operation direction display unit without requiring much time and effort on an existing operation string of a blind.

  In the invention according to the present application, in order to solve this problem, a short first mark and a second mark indicating an operation direction are formed at intervals on a continuous body such as a string or a cable.

  Further, the first mark portion and the second mark portion are formed at appropriate positions that can be recognized by the operator of the blind operation string.

  Further, as another solution, an oblique opening for attaching to the operation string is formed on the operation direction indicating assisting tool on which the mark indicating the operation direction is formed.

  With the configuration of the present invention, the operation direction is clearly displayed without conspicuous, and the user can easily grasp the operation direction, the rotation direction, or the connection direction of the cable or the like.

  In addition, an operation direction display unit can be provided on an existing blind operation string without requiring much labor.

  The best mode for carrying out the invention will be described with reference to FIGS.

  FIG. 4 shows a blind operation string 24 according to the first embodiment of the present invention having the same operation function as that of the conventional blind operation string shown in FIG. The blind operation string 24 is formed with a first mark portion 25, a second mark portion 26, and no-mark portions 27, 28, 29, and 30 in this order.

  The first mark portion 25 and the second mark portion 26 are formed adjacent to each other, and the second mark portion 26 and the next first mark portion 25 are formed with the non-marked portions 27 to 30 therebetween. Yes.

  The first mark portion 25 and the second mark 26 are extremely short, and the no-mark portion 27 is long. For example, the first mark portion 25 is formed extremely short by sewing a thread having a lighter color than the non-mark portions 27, 28, 29, and 30 and winding it several times to a dozen times, and the second mark portion 26 is not formed. It is formed extremely short by sewing and fixing a thread having a color darker than that of the mark portions 27, 28, 29, and 30 and winding it several times to a dozen times.

  In order to open the blind by operating the blind operating string 24, the unmarked portion 29 adjacent to the bright first mark portion 25 indicating the direction to be drawn is pulled in the O (Open) direction, and the blind is closed. Draws the mark-free part 27 adjacent to the dark second mark part 26 indicating the direction to be drawn in the C (Close) direction.

  The length of the mark-free portion 29 is set to an appropriate length that can be recognized by the user, for example, 30 cm to 100 cm.

  In this way, only by looking at the arrangement relationship between the first mark portion 25 and the non-mark portion 29 or the arrangement relationship between the second mark portion 26 and the no-mark portion 27, the blind operation string can be used to operate the blind. The portion to be drawn can be easily determined.

Further, since the first mark portion 25 and the second mark 26 are extremely short and the non-mark portion 27 is formed long, the first mark portion 25 and the second mark 26 do not stand out.
Furthermore, the first mark portion 25 and the second mark 26 are made inconspicuous by configuring them with bright and dark colors similar to the non-mark portions 27, 28, 29, and 30.

  FIG. 5 shows a blind operation string 30 which is a second embodiment of the present invention having an operation function superior to that of the conventional louver operation string shown in FIG. The blind operation string 30 has a first mark portion 31 and a second mark portion 32 formed at appropriate positions that can be recognized by the operator.

  This figure shows the most preferred embodiment when the louver is installed in a vertical direction, in other words, the louver is applied to a blind which is operated to receive light from the left direction and to receive light from the right direction. (A) is a state in which the blind operation string 30 is operated to take in light from the left direction, and (c) is a state in which the blind operation string 30 is operated to take in light from the right direction. (B) is the state in which the blind operating string 30 is operated so as to take in light from the front.

  As shown in (a), the second mark portion 32 is formed at the lowest position when operated to take in light from the left direction.

  As shown in (c), the first mark portion 31 is formed at a position that is the lowest when operated so as to take in light from the right direction.

  If comprised in this way, when it will be in the state as shown in (b), the direction of a louver will be in a neutral state, and it can take in the light from a front.

  As can be understood from the operation examples (a), (b), and (c), it is very easy for the operator to understand that the state of the louver is changed by pulling down the upper mark.

  The positions of the first mark portion 31 and the second mark 32 shown in this figure are the most preferable form, but the positions of the first mark portion 31 and the second mark 32 may be any other positions. .

  The first mark portion 31 and the second mark 32 are formed extremely short. For example, the first mark portion 31 is formed extremely short by sewing and fixing a thread having a lighter color than the non-mark portion 30 and winding it several times to a dozen times, and the second mark portion 32 is formed without the mark portion 30. It is formed extremely short by sewing and fixing a thread of a darker color than the same color and winding it several to dozens of times.

  Needless to say, this operation string is applicable to blinds in which the louver is installed in the horizontal direction, in other words, the louver is operated in a state where light from above is taken in and in a state where light from above is not taken in.

  FIG. 6 shows an embodiment of a novel operation string assisting device which eliminates the difficulty of attaching the operation string assisting device shown in FIG.

  The operation string assisting tool 35 is a tubular body loosely fitted to the operation string 1 as in the conventional assisting tool. For example, the first mark portion 36 colored yellow and the second mark portion colored black 37.

In addition to this configuration, the operating string assisting tool 35 is formed with an opening 38 formed in the tube so as to be oblique to the tube axis.
The width of the opening 38 is slightly smaller than the thickness of the operation cord 1.

Since the operation string assisting tool 35 is loosely fitted to the operation string 1, it is always below the blind operation string 1.
In order to open the blind by operating the operation string 1 to which the operation string auxiliary tool 35 is attached, the string 14 on the first mark portion 36 side colored yellow indicating the direction to be pulled is opened and closed. In order to close, the string 15 on the second mark portion 37 side colored in black indicating the direction to be pulled is pulled.

  Since the opening portion 38 having a size slightly smaller than the thickness of the operation string 1 is formed in the operation string assisting device 35, the operation string assisting device 35 can be easily attached to the operation string 1 through this opening. Can be attached to. Moreover, since the opening is formed in the pipe body obliquely with the pipe axis, it does not fall off the string.

FIG. 7 shows an embodiment applied to a rotating body.
In the rotating body 16 shown in this figure, a mark portion 17 composed of a first mark portion 18 colored in yellow and a second mark portion 19 colored in black is formed at an appropriate interval.
The size of the mark portion 17 is sufficiently smaller than other portions where the mark portion is not formed.

  When operating the rotating body 16, for example, when opening something, the rotating body 16 is rotated in the direction of the yellow first mark portion 18 indicating the direction to be rotated for opening, and when closing, the direction to be rotated for closing is determined. The rotating body 16 is rotated in the direction of the black second mark portion 19 shown.

  In this way, it is possible to easily determine the direction of rotation for operation only by looking at the arrangement relationship between the first mark portion 18 and the second mark portion 19 of the mark 17.

  If the mark 17 is formed by appropriate unevenness in addition to the color shown in the embodiment, the visually impaired person can easily determine the rotation direction.

  When the operation is performed by rotating the handle, a similar mark is provided on the handle.

  As is apparent from the above description, the present invention can notify the operation direction of the annular body or the rotating body with a very simple configuration and is extremely useful.

  The blind operating string has an infinite length in a ring shape, but this configuration can also be applied to cables of various electric devices having a finite length. When the main device of the adjustment console and the auxiliary device such as a television camera are connected, it is possible to easily determine which device is connected to which side of the connection cable.

The illustrated color is an example, and any identifiable color can be used.
In addition to the cylindrical string shown in the embodiment, such a configuration can be applied to a belt such as a flat plate.
