The utility model belongs to the technical field of passenger elevator accessories, and particularly relates to a handrail device for a passenger elevator.

Background

The passenger elevator is a large electromechanical device which is used for carrying people and can vertically lift, and is a vertical lift taking a motor as power. Passenger ladders are generally applied to high-rise buildings, in living areas, for more than 30 floors of households, climbing stairs every day is unrealistic, the passenger ladders basically become the passengers who need to climb up the stairs, however, some households often feel dizziness when riding the passenger ladders which are lifted vertically because of high terrorism or uncomfortable vertical acceleration, and some households can cause claustrophobia in a narrow passenger ladder car, so that if a device for leaning by the passengers can be arranged in the passenger ladders, the discomfort caused by riding the elevator can be greatly reduced. However, it is not practical to install seats in narrow passenger ladders, on the one hand reducing the passenger carrying capacity of the passenger ladder and on the other hand also affecting the cargo carrying capacity of the passenger ladder. In view of the foregoing, there is a need for a device that does not occupy passenger space and that can also be used for a particular passenger to lean against.

Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explanation of the present utility model and is not to be construed as limiting the present utility model, and modifications to the present embodiment, which may not creatively contribute to the present utility model as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present utility model.

Examples: the handrail device for a passenger elevator comprises a guide rail groove 101 arranged on a car 1, a retraction groove 102 positioned on the inner side of the guide rail groove 101, a handrail unit 2 arranged in the guide rail groove 101, and a friction plate unit 3 arranged in the retraction groove 102 and jacking up the handrail unit 2 outwards. The guide rail groove 101 extends vertically along the side face of the car 1 and is outwardly grooved, the highest position of the guide rail groove 101 is 1200mm, and the lowest position of the guide rail groove 101 is 800mm, namely, the range of the height of the handrail unit 2 is adjusted, so that the guide rail groove can be suitable for passengers with different heights. The retreating groove 102 is located on the inner groove surface of the rail groove 101, and in which the friction plate unit 3 is installed, when the passenger leans against the armrest unit 2, the inner end of the armrest unit 2 is pressed against the friction plate unit 3, so that the armrest unit 2 is kept fixed in height while the passenger is seated.

The armrest unit 2 includes an abutment plate 201, an armrest pillar 202 provided on an inner end of the abutment plate 201, and a pressing plate 203 provided on an inner end of the armrest pillar 202; the friction plate unit 3 includes a friction plate 301 for supporting the pressing plate 203. Referring to fig. 1 and 3, the leaning plate 201 is entirely of an arc-shaped structure for conforming to the shape of the buttocks of the passenger. The handrail post 202 is inserted and installed in the guide rail groove 101, the width of the handrail post 202 is matched with the guide rail groove 101, the extrusion plate 203 is arranged on the inner end of the handrail post 202, the extrusion plate 203 is made of materials with certain elasticity and large surface friction force, such as artificial synthetic rubber, the elasticity of the extrusion plate 203 enables passengers to obtain certain buffering effect when leaning on the plate 201, friction force to the friction plate 301 can be increased, and the height position of the friction plate 301 is further fixed when the passengers use the leaning plate 201, so that the passengers are prevented from sliding down.

The friction plate unit 3 further includes a jack spring 302 provided on the inner groove surface of the retraction groove 102 for jack the friction plate 301 outward. Referring to fig. 4, the jack-up spring 302 is provided to enable the friction plate 301 to have an inwardly contracted elastic characteristic, so that the friction plate can be buffered inwardly when a passenger depends on the friction plate to obtain a further buffering effect. And the jack-up springs 302 are respectively arranged on the upper side and the lower side of the friction plate 301, for example, when a higher passenger uses the seat, the leaning plate 201 is adjusted to the upper side, so that when the passenger takes the seat, the passenger only presses the jack-up springs 302 above the friction plate 301, and the friction plate 301 is enabled to incline upwards, so that the angle of the leaning plate 201 is finely adjusted, and the effect of meeting the sitting posture of the passenger is better.

The handrail comprises a handrail body 202, a guide rail groove 101, a limit groove 103 arranged on the inner side surface of the guide rail groove 101, and a limit block unit 4 arranged on the handrail body 202 and used for being clamped with the limit groove 103. Referring to fig. 5, some passengers do not want to use the leaning function of the armrest, but just want to hold the armrest, so that the process of holding does not have an inward pressing action, which makes the armrest column 202 unable to obtain a supporting effect from the friction plate 301 to move downward. The stopper units 4 provided on the side of the armrest pillar 202 can give a certain supporting force when the passenger is in the hand.

The stopper unit 4 includes a stopper 401, an unlocking ball 402 provided at the outer end of the stopper 401, and a locking spring 403 for pushing up the stopper 401 outward. When a passenger uses a large force, the unlocking ball 402 drives the limiting block 401 to be separated from the limiting groove 103, the large force can be achieved only when the passenger deliberately applies force, and the unlocking ball 402 cannot be separated from the limiting groove 103 in the normal hand-holding process. And when leaning, the leaning force can easily separate the unlocking ball head 402 from the limit groove 103, so that the inward moving process of the leaning plate 201 is not influenced.

The stopper unit 4 further includes an inner inclined surface groove 404 provided on the stopper 401, and an inner inclined surface block 405 for jacking up the inner inclined surface groove 404 inward. Some passengers do not have enough force to disengage the unlocking ball 402 from the limiting groove 103, and referring to fig. 6, in this case, only the inner inclined surface block 405 needs to be pressed inwards, so that the inner inclined surface block 405 presses the limiting block 401 inwards by pressing the inner inclined surface groove 404, and the unlocking ball 402 can be disengaged from the limiting groove 103. Also, the inner ramp block 405 is released, and the unlocking ball 402 can return to the limit groove 103 under the action of the locking spring 403. Referring to fig. 5, a plurality of limit grooves 103 are provided along the rail groove 101 to facilitate the adjustment of the armrest posts 202 to different heights.

The stopper unit 4 further includes an unlocking post 406 provided on the inner ramp block 405 with its tip extending to the outside of the armrest post 202. Referring to fig. 7, the unlocking post 406 extends upward onto the top surface of the armrest post 202, and the inner ramp block 405 can be moved downward by pressing the unlocking post 406, thereby facilitating the pressing action of the occupant.

The armrest unit 2 further includes a rotation hole 204 provided on the armrest post 202, and a rotation post unit 5 installed in the rotation hole 204 and used for adjusting the angle of the abutment plate 201. The armrest unit 2 further includes a mounting groove 205 provided on an inner side surface of the rest plate 201; the spin column unit 5 includes a spin column 501 installed in the spin hole 204 and coupled to the inner side of the installation groove 205, and a damping sleeve 502 coupled to the spin column 501. Referring to fig. 8, the damping sleeve 502 is present such that the reclining plate 201 is not rotated when a passenger leans on the reclining plate 201, and the angle adjusting effect of the reclining plate 201 can be achieved by rotating the reclining plate 201 during non-reclining.
