Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a kind of fire escape device, which can be installed in a high-rise building and safely reach the ground from a high place.

[Prior Art] The inventor of the present invention consists of a life-saving cage that can accommodate a predetermined number of people in Sho 60-20614, and an elevating body that is hung from the life-saving cage and can be vertically moved to a mounting portion of a building. , The lifting body has a box shape, rotatably supports a winding drum around which a rope having one end fixed to the mounting portion is rotatably supported, and a worm gear is fixed to a side surface of the winding drum, and A worm that meshes with the worm gear is separately rotatably supported, and the rotation speed of the winding drum can be reduced by the meshing of the worm and the worm gear. Further, two tightening rings are provided at both ends of the shaft portion of the worm. A bolt that presses each tightening ring through a spring and a steel ball is provided, and a frictional force with respect to the worm of the tightening ring is obtained by each bolt so that the rotation speed of the worm can be adjusted. Configured It filed fire rescue device according to claim, but, fire rescue apparatus described above apply only to the building below the fifth floor, the more tall buildings were unable use.

[Problems to be Solved by the Invention] The present invention is intended to develop a lifesaving device which is applicable to a high-rise building except for its drawbacks and which is improved by keeping the advantages of the above invention as it is.

[Means for Solving the Problems] In the present invention, the gear B (4) is meshed below the gear A (3) that is in fixed contact with the drum shaft (22), and the gear B (4) is provided on the side of the gear B (4). One rod (41) is fixed, two tightening rings (5) and one switch (55) are fixed to the rod (41).
A roller (51) is provided below the (5), and the roller (51)
This is applied to a high-rise building in which the tightening ring (5) is rubbed with to increase the frictional force of the whole of the present invention and the descent rate is stable.

Now, the solution means will be described with reference to the drawings. As shown in FIG. 1 and FIG.
(1), winding drum (2), gear A (3), gear B (4), and tightening ring (5) are included, and a cap (11) is provided at an appropriate place of the case (1). Further, the winding drum (2) is provided at a central position inside the case (1), and there is an annular concave portion around the winding drum (2), and the rope (21) is wound around the winding concave portion, and A drum shaft (22) is provided at a central position on one side of the attached drum (2), and the drum shaft (22) is supported inside the cap (11) by one bearing (23). ), The gear A (3) is fixed by a set bolt (31), the gear A (3) is supported on the case (1) by a bearing (32), and the lower side thereof is a gear B. (4) and the gear, and one rod on the side of gear B (4)
(41) is fixed, the rod (41) is connected to a handwheel (not shown in the drawing) provided outside the case (1), and vibration of the handwheel causes the rod (41) to move to the gear B (4). ) And the gear A (3), and the rope (21) is wound in the winding drum (2).

The rod (41) is supported by a bearing (42), on which one switch (55) and two tightening rings (5) are fixedly mounted, and the two tightening rings (5) have some surfaces. The uneven shape of the roller is shown (see Fig. 3), and the rollers are placed below the two tightening rings (5).
(51) is provided, each roller (51) is located in the uneven shape, and when one roller (51) is located in the uneven recess, the other roller (15) is located at the convex edge. So, Laura (51)
A good friction force can be maintained between the tightening ring (5) and the tightening ring (5), the operation of the rod (41) goes smoothly, and one roller rod (52) penetrates the center of the roller (51). Roller rod (5
Install a spring (53) underneath (2) and use one adjustment bolt (5
4) Screw the nut on the case with the case, fix the adjusting bolt (54) under the spring (53), adjust the position of the adjusting bolt (54) and compress the spring (53), then press the roller (51). An appropriate frictional force is generated between the tightening ring and the tightening ring (5). Further, there is a control switch (55) on the left side of the two tightening rings (5) (see FIG. 4), and when using this device, if the bolt (551) of the switch (55) is released, The device will start.

[Operation] Since the present invention has the above-described structure, when using it, a life basket (6) is hung below the present invention as shown in FIG. After getting on and releasing the switch (55), the weight of the person starts the winding drum (2) and at the same time pulls out the rope (21) to gradually lower the present invention. Also,
The descending speed is determined by the rotation speed of the winding drum (2), the gear A (3) and the winding drum (2) have the same rotation speed, and the gear A (3) and the gear B (4) are meshed. Therefore, the gear B (4) is increased in speed by the transmission of the gear A (3), but the gear B (4) is increased.
Lot (41) has a slow rotation due to the friction between the tightening ring (5) and the roller (51), so that gravity does not drop when a person is riding on it. Protect your descending humans from falling into a fire.

[Advantage of Invention] Therefore, in the present invention, the combination of the concavo-convex tightening ring (5) and the roller (51) increases the frictional force of each other, resulting in superior descent than the previous invention, and It is a lifesaving device full of practicality.
