It is provided so as to extend to the grip side of 0. The second ratchet 29 is urged by a spring 37 around a shaft 33 so as to always mesh with the second gear 28 to engage the clutch.

Next, the operation of the device according to the present invention will be described. (1) Preparation of Tatami Floor 10 and Tatami Table 11 The tatami floor 10 is placed on the work table 12. A tatami mat 11 is attached to one end of the short side of the tatami floor 10 in advance. Here, as shown in FIG. 3, the mounting table 15 at one end of the work table 12 is raised on the top plate 13, and the end of the tatami floor 10 on which the tatami mat 11 is not yet mounted is placed on the table 15. To the stopper 17 on the opposite side of Then, a gap is formed between the tatami floor 10 and the top plate 13, so that the tatami floor 10 is pushed from above to be slightly curved downward at the center in the longitudinal direction.

(2) Inserting process of the tatami mat 11 As shown in FIG. 1A, the inner wall of the cylindrical frame 20 and the pin 1
8 and the leading end of the tatami mat 11 is inserted through the tatami mat insertion slot 22 of the holding means 21. That is, the gripping lever 18 of the eccentric shaft portion 19 is pressed by pushing the handle 30 in the rearward direction while holding the switching lever 38 of the handle 30 to release the engagement between the second ratchet 29 and the tooth surface of the second gear 28. Is rotated in the depth direction (the direction of the arrow in FIG. 1A). Then, as viewed from the tatami surface insertion port 22 of the cylindrical frame 20, the gap on the near side between the inner wall of the cylindrical frame 20 and the outer wall of the holding rod 18 is widened. Insert one end. At this time, the meshing position of the first ratchet 26 with the first gear 25 may be either the near side or the far side.

(3) Step of pinching the tatami table 11 As shown in FIG. 1B, the end of the tatami table 11 is pinched between the cylindrical frame 20 and the pin 18 by turning only the pin 18 in the forward direction. Put on. That is, the first ratchet 26 is
2 to prevent the rotation of the cylindrical frame 20 by engaging with the tooth surface of the first gear 25,
While holding the second ratchet 29 from the tooth surface of the second gear 28, the handle 30 is used to rotate the holding rod 18 forward by the handle 30. Then, the end of the tatami mat 11 is sandwiched between the cylindrical frame 20 and the holding bar 18. At this time, the holding bar 18
Is slightly thicker, so that the central portion of the tatami mat 11 is slightly strongly pinched. Even when the holding bar 18 is bent and the cylindrical frame 20 bulges when the tatami table 11 is held, the tatami table 11
The whole is securely clamped.

(4) Step of Pulling Tatami Table 11 As shown in FIG.
0 and the holding rod 18 are integrally turned in the depth direction, and the tatami table 11 is pulled in and strongly attached to the tatami floor 10. That is, when the hand is released from the grip of the switching lever 38, the second ratchet 29 is engaged with the second gear 28 by the spring 37. Also, the first
The ratchet 26 is tilted in the depth direction to mesh with the first gear 25. When the handle 30 is turned in the depth direction in this state, the cylindrical frame 20 and the holding rod 18 are turned integrally in the depth direction. Then, the tatami table 11 is sandwiched between the holding bar 18 and the cylindrical frame 20, is folded and held at the edge of the tatami table insertion slot 22, and is drawn vertically at the upper edge corner of the tatami floor 10, and It will be strongly attached to the floor 10. At this time,
If the corners of the upper edge of the tatami floor 10 are not aligned with the eyes of the tatami table 11, it is desirable to align the tatami table 11 while pulling it in. Also, when the tatami mat 11 is pulled in while sliding on the upper edge of the tatami floor 10, the upper edge may be crushed,
An auxiliary member having an L-shaped cross section, such as slippery cardboard or plastic, may be interposed.

(5) Temporarily fixing step of the tatami mat 11 As shown in FIG. 1D, while the tatami mat 11 is being strongly pulled, five to seven tatami mats are placed on the tatami mat floor 10 from the top of the tatami mat 11. The temporary fixing needles 41,... Are inserted, and the tatami mat 11 is temporarily fixed to the tatami floor 10. That is, the first ratchet 26
Is tilted forward, so that the first ratchet 26
However, the cylindrical frame 20 is prevented from rotating forward and returning, and the tatami mat 11 is maintained in a strongly pulled state.
In this state, about 5 to 7 temporary fixing needles 41 are inserted from the top of the tatami table 11 to the short sides of the tatami floor 10,
The tatami mat 11 and the tatami floor 10 are temporarily fixed.

(6) Step of Releasing Tensile Force of Tatami Table 11 As shown in FIG. 1 (e), the holding bar 18 and the cylindrical frame 20 are simultaneously returned to the original state, and the tension of the tatami table 11 is released. That is,
With the provisionally fixed state of the tatami floor 10 and the tatami table 11 kept by the temporary fixing needles 41,..., The first ratchet 26 is moved down to remove the first gear 25. At this time, the second ratchet 2
No. 9 is left engaged. In this state, the handle 30 is pulled toward the user, and the holding bar 18 and the cylindrical frame 20 are simultaneously returned by the amount of rotation, thereby releasing the tensile force of the tatami mat 11.

(7) Step of Removing Tatami Table 11 As shown in FIG. 1 (f), only the clamping bar 18 is turned forward to release the clamped tatami table 11, and the tatami table 11 is removed from the cylindrical frame 20. That is, the second ratchet 29 is released from the second gear 28 by grasping the switching lever 38,
The gripping rod 18 is turned in the depth direction by tilting the handle 30 in the depth direction while holding the switching lever 38. Since the first ratchet 26 prevents the first gear 25 from rotating in the depth direction, only the holding rod 18 rotates and the cylindrical frame 2 is rotated.
Since the gap between the inner walls of the tatami mat 11 is widened and the end of the tatami mat 11 held is released, the end of the tatami mat 11 is pulled out from the tatami mat insertion slot 22.

(8) Step of permanently fixing the tatami mat 11 The tatami floor 10 to which the tatami mat 11 is temporarily fixed is turned upside down on the work table 12. At this time, by returning the mounting table 15 to its original state, the tatami floor 10 becomes flat, and the tatami mat 11 is more firmly attached to the tatami floor 10. The end of the tatami table 11 is folded back to the back side of the tatami floor 10, and the tatami table 11 is permanently fixed to the tatami floor 10 with a tucker needle or a tatami thread. After the permanent fixing, all the temporarily fixed needles 41,... Temporarily fixed are pulled out.

In the above embodiment, the stopper 17 is always in the upright state. However, the present invention is not limited to this, and the stopper 17 has a hinge 42 or the like attached to the bottom as shown in FIG. This may be made freely foldable. With this configuration, when the stopper 17 is folded, the top plate 13 can be flattened so as not to hinder other operations.

In the embodiment shown in FIG. 2, two gears, a first gear 25 and a second gear 28, are used.
The cylindrical portion 34 of the second gear 28 and the cylindrical portion 35 of the second gear 28 are fitted and fixed. However, the present invention is not limited to this, and as shown in FIG. By setting the position and the meshing position of the second ratchet 29 at other positions of the same circle, one gear can be used.

If the work table of the present invention is made entirely of a lightweight metal such as aluminum, it is possible to provide a device which can be easily transported to a work site or otherwise arranged.

In the above embodiment, the work table 12 is an example in which the four pillars 14,... Are fixedly mounted on one top plate 13, but the present invention is not limited to this. Top plate 1
3 is formed from two plates cut at the center in the longitudinal direction,
Further, the pillar 14 also supports an arm having a long hole on the side of the top plate 13 in the longitudinal direction with a pin or the like, and also supports the arm on the pillar 14 with a pin. The top plate 13 of the work table 12 may be folded in two from the center and the pillar 14 may be folded so as to be slidably fitted in the long hole. With such a configuration, it is possible to provide a device that can be stored in a narrow space and that is easy to carry.
