It is set to be aligned, so that when the second part 4 and the third part 5 are connected, these connecting parts can be prevented from being exposed to the space on the second floor, and the design life can be enhanced. I am doing so. Moreover, the connection part of said 2nd, 3rd site | parts 4 and 5 is prevented from falling too much from a 2nd floor, and opening and closing of the inner door 18 provided in the 3rd site | part 5 is not impaired.
And the length adjustment of the 2nd site | part 4 is comprised so that it may adjust by cut | disconnecting the front-and-back vertical frame materials 11 and 12 site | part which protrudes upward rather than each upper edge part of the front panel body 4c and the panel body 10 suitably. Thus, consideration is given to simplifying the adjustment work.

That is, in the case where the elevator 1 is installed in a house where the ceiling height of the first floor part is higher than that of a standard house, the front and rear vertical frame members 11 and 12 of the second part 4 are cut, By setting the second floor surface to be substantially flush with the second floor, the connecting portion with the second and third portions 4 and 5 can be prevented from being exposed to the second floor space. By doing in this way, although the connection part of the 1st site | part 3 and the 2nd site | part 4 is displaced and arrange | positioned below a ceiling surface, the front panel body 4c and panel body of the 2nd site | part 4 are arrange | positioned. 10 is arranged so that the lower end edge is flush with the front and rear vertical frame members 11 and 12, even if the lower end of the second part 4 is exposed on the first floor part, Each panel body 4c, 10 is disposed in contact with the first portion 3, and there is no problem that a gap is formed in the hoistway 2 (see FIG. 1).
Thus, by adjusting the length of the front and rear vertical frame members 11 and 12 of the second part 4, alignment with the second floor of the third part 5 is made, and the elevator 1 can be operated regardless of the ceiling height of the first floor. Can be installed. In addition, as shown in FIG. 4, adjustment of the hoistway 2 is set so that it may be made in the range of the protrusion length from the panel bodies 4c and 10 upper edge parts of the longitudinal frame members 11 and 12. FIG. At this time, by setting the vertical length dimension of each panel body 4c, 10 to the above-described length dimension, it is considered that the part without panel body 4c, 10 does not face the first floor part. .

In the present embodiment configured as described, the elevator 1 winds and unwinds the belt body 13a based on the operation of an operating tool (not shown), whereby the lifting body 17 moves up and down in the hoistway 2. In this case, the hoistway 2 is divided into the first, second, and third parts 4, 5 and 6, and the first floor or the second floor. It can be built in and does not require large-scale roof construction from the second floor ceiling to the roof. As a result, it can be easily and inexpensively installed in an existing house in a short time.
In addition, the vertical length of the second portion 4 facing the ceiling between the first floor and the second floor is set to be longer than the vertical length of the ceiling, and the length of the second portion 4 is adjusted. In a simple operation, the position of the connecting portion between the second part 4 and the third part 5 can be aligned with respect to the second-floor floor surface, and the elevator 1 corresponding to the first-floor ceiling height of an individual house can be obtained. As a result, workability is improved, and the first, second, and third parts 3, 4, and 5 can be standardized with preset length dimensions, and each can be mass-produced. It can contribute to cost reduction.

  Furthermore, in the case where the present invention is implemented, when standardizing the first and third parts 3 and 5, the vertical length of the first part 3 is changed from the floor surface upstairs to the ceiling surface. Since the height is set to be equal to or shorter than the height, the assembling work of the respective parts 3, 4, 5 can be facilitated and the working time can be shortened.

  Moreover, in this case, the vertical length of the second part 4 is set longer than the length obtained by adding the height dimension of the ceiling part to the length obtained by subtracting the vertical length of the first part from the ceiling height of the downstairs. As a result, installation work becomes easy.

Moreover, in this case, the guide body for moving and guiding the first to fourth guide rollers 19, 20, 21, 22 provided at the four corners of the elevating body 17 is used as the first, second, and third parts 3. First to first formed in front and rear longitudinal frame members 8, 9, 11, 12, 15, 16 of the pair of side pieces 3b, 3c, 4a, 4b, 5a, 5b facing the left and right sides of 4, 5, Since the six guide pieces 9a, 9b, 9c, 8b, 8c, 8d, 12a, 12b, 12c, 11b, 11c, 11d, 16a, 16b, 16c, 15b, 15c, 15d are provided, a guide body is provided separately. Therefore, the frame members 8, 9, 11, 12, 15, and 16 can be used together, the structure can be simplified, and the thickness can be reduced, contributing to compactness. In addition, by connecting the portions 3, 4, and 5, a guide surface extending over the entire length of the hoistway 2 is formed, so that the assembling work can be simplified.
Furthermore, since the first and third parts 3 and 5 are configured with face plates on the left and right side surfaces 3b, 3c, 5a and 5b, respectively, of the three sides with the wall surface of the housing as one side surface, When installing, the degree of freedom in selecting the attachment location can be increased.

  Further, the vertical length of each panel body 4c, 10 of the second member 4 is equal to or longer than the standard ceiling height minus the vertical length of the first portion 3, and the standard ceiling. Same as or longer than the length of the first part 3 minus the vertical length of the first part 3 plus the length from the first floor ceiling to the second floor, that is, the height of the first floor ceiling. The length of the second member 4 is adjusted by adjusting the lengths of the protruding portions of the front and rear vertical frame members 11 and 12 protruding upward from the panel bodies 4c and 10 respectively. Since it is the structure to adjust, it is not necessary to cut | disconnect about each panel body 4c, 10, it can cut and adjust only the vertical frame materials 11 and 12, and adjustment work is easy and can also be performed on-site. Thus, workability can be improved.

  Further, in this structure, the front and rear vertical frame members 8, 9, 11, 12, 15, 16 are connected to each other by being inserted into the rectangular tube holes 8e, 9d, 11e, 12d, 15e, 16d formed therein. Since it is configured to be performed via the piece 23, the connecting portion does not become thick unlike the case where the two members are stacked and connected, and further downsizing can be achieved.

  Furthermore, the elevating body 17 includes first to third guide rollers 19, 20, 21 provided at four corners, the guide pieces 9 a, 12 a, 16 a, 9 b, 12 b, 16 b, 9 c, 12 c, 16 c, 8 b, 11b, 15b, 8c, 11c, 15c as a result of moving up and down in a state of receiving movement guidance, the support of the lifting body 17 is dispersed at the four corners, the rigidity of the lifting body 17 itself can be reduced, It is not necessary to make the guide pieces 9a, 12a, 16a, 9b, 12b, 16b, 9c, 12c, 16c, 8b, 11b, 15b, 8c, 11c, and 15c exceptionally sturdy, and can be made compact. . In addition, since the four corners of the lifting body 17 are supported, the posture of the lifting body 17 with respect to the hoistway 2 can be easily corrected, and a stable and smooth vertical lifting motion can be realized.

Of course, the present invention is not limited to the above-described embodiment, and a first guide roller having a support shaft facing in the left-right direction and a second shaft having a support shaft facing in the front-rear direction are provided on the elevating body.
