Description

  Embodiments described herein relate generally to an operation panel of a passenger conveyor.

  Generally, passenger panels such as escalators and moving walkways are provided with operation panels equipped with button devices for controlling the operation of the passenger conveyor. In some button devices provided on the operation panel, a button cover may be attached so that it is not accidentally pressed during normal times, such as an emergency stop button for stopping a passenger conveyor in an emergency.

  Such a button cover is made of a transparent hard acrylic resin, and when the button is pressed, it is necessary to push the button after breaking the button cover. However, if the button cover is pushed and broken when the button device is pressed, sharply pointed burrs are generated on the broken button cover, and there is a risk of injury when the finger that pushed the button is pulled out.

  Therefore, an engagement groove is provided in the button frame surrounding the switch, and a protrusion provided on the button cover is engaged with the engagement groove, thereby holding the button cover inside the button frame and pressing the button. A button device has been proposed in which when the button cover is pushed in with a fingertip, the protrusion is disengaged from the engaging groove, and the button cover is displaced to press the switch (for example, Patent Document 1 below).

  However, in Patent Document 1, since the button cover has high rigidity and it is difficult to hold the button cover on the button frame, the button frame engaging groove is used to recover after the button device is pressed. It is necessary to engage the protrusion of the button cover. Further, the protrusion of the button cover may be broken when the protrusion of the button cover is removed from the engaging groove, and the button cover may not be repeatedly used.

Opposing surfaces 34 are provided to face each other with a gap therebetween.

  When the cap 31 is fixed to the outside of the protector 29, the facing surface 34 faces the end surface 29 a of the protector 29 with a space therebetween, and an annular groove 35 is formed between the facing surface 34 and the end surface 29 a of the protector 29. . The cap 31 is provided with a window portion 36 that penetrates the facing surface 34 at a position facing the opening 29 b of the cylindrical protector 29.

  The cover 37 is an elastically deformable thin plate-like member formed of a soft acrylic resin or the like, and its peripheral edge is formed in an annular groove 35 formed between the end surface 29a of the protector 29 and the opposing surface 34 of the cap 31. An insertion portion 37a to be inserted is formed. In the present embodiment, the cover 37 has a disc shape, and the insertion portion 37 a of the cover 37 is inserted in the entire circumference of the annular groove 35.

  The thickness T of the cover 37 is set to be smaller than the groove width W of the annular groove 35, that is, the distance W between the end surface 29 a of the protector 29 and the facing surface 34 of the cap 31. When the insertion portion 37a is inserted into the annular groove 35, such a cover 37 is held on the end surface 29a side of the protector 29 while being movable in the annular groove 35, and covers the opening 29b from the outside to cover the cap 31. The window part 36 provided in the opposing surface 34 and the opening part 29b are partitioned off.

  Thus, the cover 37 held in the annular groove 35 faces the switch 28 with a gap D therebetween. In the present embodiment, as described above, the switch 28 is disposed inside the panel 21, and the distance D between the switch 28 and the cover 37 is set larger than the distance H from the panel 21 to the cover 37.

  Here, taking an example of various dimensions of the button device 22 provided on the operation panel 20 based on FIG. 3, the diameter R1 of the opening 29b of the protector 29 is 25 mm, and the outer diameter R2 of the end surface 29a of the protector 29 is 30 mm. When the distance H from the panel 21 to the cover 37 corresponding to the protrusion amount of the protector 29 is 4 mm, the diameter R3 of the cover 37 is 29 mm, the thickness T of the cover 37 is 0.1 to 0.3 mm, and the annular groove 35 The groove width W can be 1 mm, and the distance D between the switch 28 and the cover 37 can be 8 mm.

  In the operation panel 20 having such a configuration, when the button device 22 is pressed and the cover 37 is pushed in from the window portion 36 of the cap 31, the cover 37 is bent and the opening 29b of the protector 29 is bent as shown in FIG. The switch 28 is depressed and the switch 28 is pressed.

  At this time, in this embodiment, since the groove width W of the annular groove 35 is larger than the thickness T of the cover 37 and the cover 37 is held in a movable state in the annular groove 35, the cover 37 is pushed and curved. The insertion portion 37 a of the cover 37 is detached from the annular groove 35 and falls into the opening 29 b of the cylindrical protector 29. After the switch 28 is pressed, the curved cover 37 is held in the opening 29b. When the button device 22 is pressed in this way, the curved cover 37 is held in the opening 29b, so that it can be easily determined that the button device 22 has been operated.

  Next, in order to recover the pressed button device 22, the cap 31 fixed to the protector 29 is removed, and the cover 37 fitted in the opening 29 b of the protector 29 is taken out. Then, in a state where the removed cover 37 is disposed between the end surface 29 a of the protector 29 and the facing surface 34 of the cap 31, the screw portion 32 of the cap 31 and the screw portion 30 of the protector 29 are screwed together to form an annular shape. The cap 31 is fixed to the outside of the protector 29 while holding the cover 37 in the groove 35. Thereby, the state before the pressing operation as shown in FIG. 3 is restored, and the button device 22 can be reused.

  In the present embodiment as described above, since the cap 31 that holds the cover 37 with the protector 29 is detachably fixed to the protector 29, the protector 29 is removed by removing the cap 31 after the cover 37 is pushed in. By removing the cover 37 fitted in the opening 29b, the button device 22 can be easily restored.

  Further, in the present embodiment, the cover 37 is curved and the switch 28 is operated. Therefore, the cover 37 does not need to be broken, and the fingertip is not injured and can be operated safely.

  Furthermore, in the present embodiment, the groove width W of the annular groove 35 is set larger than the thickness T of the cover 37, and the elastic cover 37 is held in a movable state in the annular groove 35. The pressing force required to operate the switch 28 by bending the switch 37 can be easily set to an appropriate magnitude.

  That is, when the peripheral edge portion of the cover 37 (that is, the insertion portion 37a) is sandwiched and fixed between the end surface 29a of the protector 29 and the facing surface 34 of the cap 31, the pressing force necessary for operating the switch 28 is inserted. Since it changes according to the magnitude of the clamping force acting on the portion 37a, in order to make the pressing force constant, the tightening amount of the cap 31 with respect to the protector 29 must be accurately managed, and the working efficiency is lowered. On the other hand, in the present embodiment, the cover 37 having elasticity is held in a movable state in the annular groove 35 and does not affect the tightening of the cap 31 with respect to the protector 29. The pressing force required to operate the switch 28 during the restoration work can be easily set to an appropriate magnitude.

  In addition, in the present embodiment, the cover 37 having elasticity is held in a state where it can move within the annular groove 35, and when the cover 37 is pushed and curved, the insertion portion 37a of the cover 37 is detached from the annular groove 35. A gap D between the switch 28 and the cover 37 can be set large to prevent the switch 28 from malfunctioning.

  In particular, the distance D between the switch 28 and the cover 37 is set to be larger than the distance H from the panel 21 to the cover 37 as in this embodiment, and the switch 28 is disposed inside the panel 21, so that a roller for a shopping cart or stroller is used. Even when an object such as a collision hits the button device 22 protruding from the panel 21, it is possible to prevent the switch 28 from operating erroneously.

  In the above-described embodiment, the case where the cover 37 is provided in a disc shape and the insertion portion 37a of the cover 37 is inserted in the entire circumference of the annular groove 35 has been described. For example, FIGS. ), A plurality of insertion portions 37a may be provided at equal intervals in the circumferential direction of the annular groove 35. With this configuration, the notch 38 is formed between the insertion portions 37a adjacent to each other in the circumferential direction, so that it is possible to prevent wrinkles from being generated in the cover 37 when the cover 37 is pushed and curved. The cover 37 can be pushed in smoothly and the switch 28 can be operated.

  As mentioned above, although embodiment of this invention was described, these embodiment was shown as an example and is not intending limiting the range of invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the invention described in the claims and equivalents thereof as well as included in the scope and gist of the invention.
