JP5556980B2 - Lift staircase with weight - Google Patents

Description

  The present invention relates to an ascending / descending staircase using a weight that rises alternately left and right at regular intervals using the weight of the weight.

  As a conventional technology, a common cage for one person riding a car and a combined weight of a balanced weight are connected with a wire rope and suspended in a balanced manner by a pulley at the top of the hoistway. By turning the handle fixed to the passenger car lightly by its own power, it is guided to a tooth-type guide rail that is independently fixed by a gear built in the handle, and the passenger car moves lightly up and down There is a manual self-propelled lifting device. (See Patent Document 1)

In addition, as another prior art, a guide rail is provided along the ascending / descending direction, an elevating table that travels along the guide rail is provided, an elevating unit that travels the elevating table is provided, and the elevating unit is driven manually. In the manual lifting device in which the driving means to be moved is provided on the lifting platform, and the user can manually lift and lower the driving means on the lifting platform, the lifting assisting means for assisting the lifting force of the front lifting platform is provided. There is a manual lifting device characterized in that the lifting means can be lifted by operating the driving means with a small force with the assistance of the lifting assist means. (See Patent Document 2)

14, a roll shutter, made of attached to the side of the left stairs box 2b, increases at the same time when the left stairs box 2b is increased, is intended to serve as a blind. (See Figure 2)

  Reference numerals 15a and 15b denote doors. (See Figs. 13 and 14)

  Reference numeral 16 denotes an upper floor door. (See Figs. 13 and 14)

Next, the usage state of the elevating staircase 1 by the weight will be described.
1) Open the entrance door 15b from the lower floor (first floor) and enter the interior. (See Figures 1 and 2)
2) Place the left foot in the left staircase box 2b and the right foot in the right staircase box 2a. (See Figures 1 and 2)
3) By depressing the pedal P of the release pedal KP, the arm A and the chain KS are operated, the pressing plate 7c2 is retracted, and is removed from the notch groove 7a1 of the main stopper shaft 7a of the main stopper 7, whereby one weight 8 The left staircase box 2b naturally rises one step. ) At this time, the brake roller 5c of the right guide brake 5 passes through the upper surface 3a2 of the locking portion 3a and enters the upper locking portion 3a, and the brake rollers 5c and 5c are locked even if the left foot is strung with tension. It is locked to the lower surfaces 3a1 and 3a1 of the parts 3a and 3a and does not fall down. (See Fig. 2, Fig. 4 and Fig. 8)
4) Next, by slightly raising the right foot, the other weight 8 is lowered and the right staircase box 2a is naturally raised. (Also at this time, the brake roller 6c of the left guide brake 6 passes through the upper surface 3a2 of the locking portion 3a and enters the locking portion 3a on the upper level. The lower surfaces 31a and 3a1 of the stoppers 3a and 3a are not locked and lowered (see FIG. 6).
5) By repeating the above 3) and 4), the moving staircase box 2 (the left staircase box 2b and the right staircase box 2a) rises alternately by 1P.
6) When reaching the upper floor (second floor), the vertical shafts 10b and 10b move downward by the upper stoppers 4 and 4 being pushed downward by the horizontal shaft 10c of the joint plate control unit 10. Accordingly, the compression spring 10a1 is actuated by the tapered groove 10b1, pushes out the joint plate 10a, passes through the joint plate entrance / exit 2a2 and 2b2, and connects the left staircase box 2b and the right staircase box 2a in the horizontal direction. At this time, the holding stopper 10d is disengaged from the groove 10b2, and holds the vertical shaft 10b in the current position. In this state, the upper floor door 16 (entrance door 15b) can be opened to go to the second floor. (See Figures 15 and 16)
7) Next, when descending from the upper floor (second floor) to the lower floor, the upper floor door 16 (entrance door 15a) is opened and both feet are placed on the moving staircase box 2. (See Figures 15 and 16)
8) When the guide brake lever 6d provided on the handrail 13 is gripped, the guide bar 6a rises around the fulcrum ST2, the hook piece 6b4 rises, the pin 6b2 rises, and the brake roller 6c around the fulcrum ST3. Operates inward (downward). (Disengages from the locking portion 3a)
At the same time, when the guide brake 5d is gripped, the guide lever 5a rises with the fulcrum ST as an axis, the plate 5b3 rises, the pin 5b2 rises, and the brake roller 5c operates inward (downward) with the fulcrum ST1 as an axis. To do. (Disengage from the locking portion 3a) (see FIGS. 4 and 6)
9) Although it descends in this state, when the pedal 9c of the box brake 9 is depressed, the brake drum 9a is actuated and descends while gradually applying the brake. In the case of an emergency, if the guide brakes 5d and 6d are released, the brake rollers 5c and 6c enter the locking portion 3a and stop. (See Figures 4, 5, and 6)
10) As it is lowered, the vertical shafts 10b and 10b come into contact with the protrusions TK on the lower surface SK in the elevating passage S and move upward, whereby the tapered groove 10b1 rises, the joint plate 10a retracts, and the above 1 ) State. (See Figure 7)
11) At the same time, when landing, the main stopper shaft 7a enters the through hole 2d, and the pressing plate 7c2 enters and locks into the notch groove 7a1, so that the state of 1) is achieved.
Further, when the person gets off, the right staircase box 2a rises by one step because the brake roller 6c of the right box 2a has no engaging portion. (See Figure 8)

Next, another usage example will be described.
When the moving staircase box 2 is on the lower floor (first floor) and another person on the upper floor (second floor) wants to go down to the lower floor (first floor), the release lever KR provided on the upper floor (second floor) is operated. As a result, the main stopper rotating body 7b is rotated 90 ° or more by the wire Y (the main stopper shaft 7a is also rotated), so that the pressing plate 7c2 is removed from the notch groove 7a1, and the moving staircase box 2 is moved by the weights 8 and 8. (Left staircase box 2b and right staircase box 2a) are automatically raised. (See Figures 1, 10, and 11)

When the staircase moving box 2 is on the upper floor (second floor) and another person on the lower floor (first floor) wants to go to the upper floor (second floor), first, the handle 11a of the guide shaft rotating tool 11 is rotated. By operating the rotating shaft 11c and the interlocking shafts 11d and 11e, the guide shaft 3 can be rotated by 90 ° or more, and the brake rollers 5c and 6c can be removed from the locking portion 3a.
In this state, by rotating the winding body 12b of the lowering tool 12 and winding the wire Y1, the receiving plate 12a pushes up the weights 8 and 8 so that the moving staircase box 2 can be lowered without resistance. It is. (See Figure 1 and Figure 10)
