Abstract

(57) [Summary] [Purpose] The light emitted from the light emitter is reflected on the running surface of the stairs to call attention to passersby. [Structure] The light emitter 4 is provided on the lower surface of the carrier 3 in the stair lift A, and the light of the light emitter is reflected on the stairway running surface.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a stair lift.

[0002]

[Prior art]

 As a conventional technique to ensure safety for people passing by on the stairs when operating a stair lift, a non-contact sensor such as an ultrasonic device detects a person or a foreign object, and then stops the transport of the transporter. There were things and warning sounds to alert the passersby.

[0003]

[Problems to be solved by the device]

 According to the above method, if the sensitivity of the ultrasonic device is too high, it will detect even things that do not hinder the lifting, and if the sensitivity is too low, the sensing accuracy will be poor and even if there is an obstacle. There was a problem of not stopping.

Further, according to the alarm sound, it is impossible to ensure safety for the hearing impaired.

Further, it has been insufficient to call a passerby's attention only by the alarm sound.

In particular, there is a problem that the alarm sound cannot be used in a place such as a museum where silence must be maintained.

In view of this, the present invention utilizes light reflection to call attention to passersby.

[0008]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention relates to a stair lift, in which a guide rail provided along a stairway is movably engaged with a transporter, and the transporter is driven by an appropriate drive device. A structure is used in which a light emitter that illuminates the stairway running surface is provided on the underside of the carrier.

[0009]

[Action]

 When refined as described above, the light emitted from the light emitter is reflected on the running surface of the stairs to call attention to passersby.

[0010]

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

A shown in FIGS. 1 and 2 is a stair lift.

The stair lift A described above includes a guide rail 2 provided along the stairs 1, a carrier 3 that is movably engaged with the guide rail (for example, a friction wheel is pressed against the guide rail), and the carrier. 3 is driven (for example, a motor with a drive speed reducer for a friction wheel) and a drive device (not shown).

A light emitter 4 that illuminates the traveling surface of the stairs 1 is provided on the lower surface of the carrier 3.

The above-mentioned light emitters 4 are arranged in the traveling direction (on the ascending side and the descending side, respectively), and as shown in FIG. It is better to install a lamp as the light emitter 4 so that it cannot be seen from the outside. 6 is closed by a transparent plate).

[0015]

【effect】

 Since the stage elevator of this invention has been refined as described above, the reflection of light from the lower surface of the carrier can alert the deaf person to attention and at the same time, keep the museum quiet. Effective in places where it does not.

Further, even in a place where the alarm sound is hard to hear, such as a noisy station, the reflection of light can alert a general passerby to the attention.
