Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a simple lifting device that raises and lowers tatami mats in living spaces on the second floor and above, such as apartments and condominiums.

[0002]

[Prior Art]

 In a two-story house or apartment, a slide-type double ladder elevator was used, and the ladder surface was slid to raise or lower by a winch. In condominiums equipped with elevators, the elevators were used after operation, but in many cases they are not working during construction.In such a case, use a crane truck or use stairs manually. I was lifting.

[0003]

[Problems to be solved by the device]

 We will provide a tatami-raising / lowering device that can be easily installed on the veranda of the room used, the deck of the corridor, etc., and can be directly pulled up or down from the ground or on a truck.

[0004]

[Means for Solving the Problems]

 The present invention solved based on the above problems will be described in detail below with reference to the drawings. FIG. 1 is a front view showing an example of the tatami lifting device body of the present invention, FIG. 2 is a right side view thereof, FIG. 3 is a partial view of the tatami lifting device body, and FIGS. FIG. 4 shows a supporter for fixing the main pole, and FIG. 5 shows a winch fixing caster bolt. In the figure, the main body of the tatami lifting device has a winch 2 installed on a base 1 and a main pole 3 standing upright in accordance with the rope direction of the winch. Two horizontal adjusting bolts 4 and two vertical adjusting bolts 5 are attached to the base 1. Reference numeral 6 is an inverted L-shaped arm pole, which is inserted into the main pole and can be freely rotated on the main pole. An arm upper and lower adjust bolt 7 as shown in FIG. 3 is attached to the lower end of the arm pole 6. 8/8 'is a pulley, 9 is a limit switch, and 10 is a wire rope.

[0005]

[Action]

 When installing the tatami mat lifting device itself, if there is a concrete fence on the veranda or the deck of the corridor, it may be installed as shown in FIG. That is, the main pole fixing supporter is fixed to the upper end of the concrete fence, the upper part of the main pole is fixed to this main pole fixing supporter, and the horizontal adjusting bolt 4 and the vertical adjusting bolt 5 are adjusted. , Insert the winch fixing adjust bolt shown in Fig. 5 between the winch fixing adjusting bolt and the wall surface, and operate so that compression force acts on the winch fixing adjusting bolt. The winch is fixed by these series of operations. The heights of eaves, eaves, and fences are generally fixed, but they differ slightly depending on the building. For these different building conditions, optimum vertical conditions can be obtained by adjusting the vertical adjustment bolt 5 and the arm vertical adjustment bolt 7. The arm pole 6 is inserted into the main pole 3 and can be freely rotated, so that when the tatami is raised or lowered, the arm can be directed outward or inward. A loading jig as shown in FIG. 7 may be attached to the tip of the wire rope 10. The tatami mat does not sway or rotate while it is being raised or lowered, allowing for safe and quick work.

[0006]

【Example】

 Example 1 A tatami lifting device shown in FIGS. 1 and 2 was prototyped and used as a replacement for the tatami mat of a two-story wooden house. The elevating device itself had only to be tied to the metal fence of the veranda with ropes, but it was able to withstand the lifting and lowering of two tatami mats in a set and achieve the intended purpose.

Example 2 A trial was carried in to bring in a tatami mat of a new 7-story condominium. The elevator wasn't ready for use yet, but the tatami-lifting device of the present invention made it possible to carry it in safely. The trial tatami mat lifting device could only be pulled up to the 5th floor because of the length of the wire rope, and it was manually transported to the higher floors.

[0008]

[Effect of the device]

 As a result of repeatedly using the prototype, the following effects were confirmed. In the case of the conventional slide type double ladder, it is possible to pull up to about the second floor and there is a problem that it is easy to roll over. However, with the present invention, it has become possible to safely raise and lower it on the third floor and above. By lengthening the wire rope used, it is possible to raise and lower it to the height of about 7th floor. Regardless of the progress of elevator construction, such as newly built condominiums, it is possible to proceed with tatami construction, and the planned promotion of tatami construction is planned. This invention was developed for raising and lowering tatami mats, but it can be used not only for raising and lowering construction equipment other than tatami mats, but also for carrying in household items such as furniture and futons when moving, which saves labor. Can be done.
