Abstract

PROBLEM TO BE SOLVED: To reduce the arranging area, and to easily lay out an arranging place in a building by arranging a space for housing doors between a gondola and a right or left side inner wall of a frame, and opening/closing the doors on the inside of the frame constitution. SOLUTION: A vertically lifting gondola 21 is housed inside a frame 20 composed of plural columns 14 erected on a stand and a laterally oppositely arranged main column 12. A cross section of an inner door 2 arranged in the gondola 21 and an outer door 1 arranged in the frame 20 are formed in a circular arc shape to be opened/closed by rotating with the center of the circular arc as the axis, and a space 3 for rotatably housing the outer door 1 and the inner door 2 is arranged between these gondola 21 and a right or left side inner wall of the frame 20. Thus, since a lifting mechanism for lifting the gondola 21 and an opening/closing mechanism of inner/outer doors 1, 2 can be compactly housed, an arranging place in a building can be easily laid out.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a home elevator.

[0002]

2. Description of the Related Art A conventional home elevator has a door that opens and closes to the left or right of the entrance, so that a doorway is large when a door storage portion is included, and a hydraulic lifting mechanism is used. Many of them are large, such as a fishing bottle type and a roll type, and require a large installation area compared to the internal volume of the gondola, and most of them have a part of the building as a structure.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to reduce the installation area so that it can be easily installed even on a narrow site of a general house, and to have a small effect on the structure and strength of the building. And a stand-alone elevator having a solid unit structure.

[0004]

In order to achieve the above object,
In the home elevator according to the present invention, a gondola is provided in which a plurality of columns are erected on a base frame, and a person is placed inside a frame configured by arranging main columns opposite to each other on the left and right, and the gondola is raised and lowered. The cross section of the inner door provided on the gondola and the outer door provided on each floor position of the frame is arc-shaped, and at each floor position the inner door and the outer door are engaged by a coupling member, and the arc is integrally formed. The door is opened and closed by pivoting about a center, a space for accommodating the door is provided between the gondola and the inner wall on the right or left side of the frame, and the door is opened and closed inside the frame structure.

Further, the gondola is raised and lowered by a pulley mechanism using chains provided on the left and right sides of the gondola, and a driving shaft driven by a motor is fixed to the driving shaft at the top of the frame. Is provided so as to be positioned above the main pillar, and a shaft of a hoisting pulley is fixedly mounted on an upper part of a hanger base attached to the left and right sides of the gondola, and a chain having one end fixed to the top of the main pillar is lifted. When the drive shaft is driven, the chain is hoisted and the gondola is lifted. The chain sent by unwinding is fixed to the other end of the chain at the lower portion of the main column via two sets of chain pulleys provided below the main column and at the lower portion of the hanger base. A pulley mechanism with an appropriate structure is a lift provided on the left and right sides of the gondola.

BEST MODE FOR CARRYING OUT THE INVENTION

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings based on an example in which the present invention is applied to a home elevator for the second floor. FIG.
Is a cross-sectional view as viewed from above, FIG. 2 is a cross-sectional view as viewed from the side, and FIG. 3 is a cross-sectional view of the main pillar as viewed from the front. Stand 15-4
A gondola 2 is provided inside a frame 20 having a pillar 14 erected at a corner and a main pillar having a U-shaped cross-section arranged right and left.
The gondola 21 is provided with an inner door 2 having an arc-shaped cross section. The inner door is connected to a pulley 17 which is rotated by a motor 18 provided at the top of the gondola by an arm 16, and the gondola on each floor of the frame is provided. An outer door 1 having an arc-shaped cross section is provided at a stop position, and a connecting member 22 that engages the outer door 1 at each floor position on the inner door 2.
A storage space 3 is provided between the gondola and the inner wall of the frame, in which the inner door 2 and the outer door 1 can be rotated and stored together.

Further, inside each of the main columns 12 disposed opposite to the left and right of the gantry 15, the drive shaft A23a and the drive shaft B23b are connected to each other by a sprocket 6 fixed to the drive shaft. Installed in the top of the gondola located at the top,
The hanger base 4 is attached to the left and right sides of the gondola, the axis of the pulley 7 is lifted above the hanger base, and the axes of the pulleys A8 and B9 for chain tension are fixed below and below the main pole, respectively. A chain fixing member 5 is screwed on the top of the chain member, and a chain 11 having one end fixed to the fixing member is engaged with the hoisting pulley 7 and mounted on the sprocket 6, and the main column is connected via a pulley B9 and a pulley A8. The other end is fixed to a chain fixing member 10 which is screwed below the lower end 12. A guide roller 13 is provided above and below the hanger base 4 so as to be rotatable and in contact with the inside of the U-shape of the main pillar 12. Further, the drive shafts A and B are driven by chains separately from the motor 19, respectively.

With this construction, when the gondola reaches the stop position on the first floor or the second floor, the inner door 2 connected to the pulley 17 driven by the motor A by the arm 16 is connected to the outer door 1. The doors can be opened and closed by engaging and rotating together with the shaft of the pulley to the storage space. When the left and right drive shafts are driven by the motor B19, the hoisting sprocket 6 has one end fixed to the fixing member 5 and hoists the chain engaged with the hoisting pulley 7 provided on the hanger base 4 to suspend the gondola. Fry. The chain that is sent out by winding is fixed to the chain fixing member 10 via the pulley B9 and the pulley A8, so that proper chain tension can be maintained. Further, the guide roller 13 can maintain the stability of the gondola.

[0010]

As described above, the elevator according to the present invention raises and lowers the gondola and the gondola inside the frame constituted by the columns erected at the four corners of the gantry and the main columns arranged on the left and right. The unit structure in which the elevating mechanism and the opening / closing mechanism of the inside and outside doors are compactly housed has little effect on the strength of the building, and the installation area is small, so that the layout of the installation place in the building is easy. In addition, it is easy to install it outdoors. In addition, high safety can be obtained by using two systems for driving the lifting chain.
