FIG. 6 is an explanatory perspective view, and FIG. 6 is a transverse cross-sectional view across the crossbar with the handle shown in FIG.

  The handle is made of metal and includes a gripping portion 1, a vertical portion 2, a hooking portion 3, and an auxiliary member 5. The main bar 6a as the main member and the cross bar 6b as the auxiliary member orthogonal to the main bar 6a are inserted into the slits ε between the main bars 6a of the grating 6 formed in a lattice shape, and the cross bar 6b is hooked on the hooking portion 3. It is a grating tool that lifts it. The gripping part 1 is formed in a predetermined length of a linear shape with a shaft shape or a cylindrical shape, and is formed with a gripping part 10 that can be gripped with a hand. Here, a cut product obtained by cutting a shaft member made of 13 mmφ steel bar into a length of 15 to 20 cm is used.

The vertical portion 2 is a metal plate-like body that hangs down in a T-shape with a constant width from substantially the center of the grip portion 1. When the grip part 1 and the latch part 3 are directly connected, workability is deteriorated. A vertical portion 2 having a predetermined length is provided to improve workability. The vertical portion 2 secures the width and thickness t ₁ of a sufficiently strong band plate-like body capable of hooking the cross bar 6 b with the hook portion 3 and lifting the grating 6. The plate surface direction of the belt-like body of the vertical portion 2 is made coincident with the longitudinal direction of the grip portion 1 (the axial direction of the shaft member) as shown in FIG. 1, and the upper end of the vertical portion 2 is welded and integrated with the grip portion 1. . The vertical portion 2 and the latching portion 3 are made of a band plate-like body that matches the plate surfaces, and the plate surface direction of the band plate-like body is made to coincide with the longitudinal direction of the grip portion 1. In the present embodiment, as many as one plate body is processed, the vertical portion 2 and the latching portion 3 are integrally manufactured.

The latching part 3 forms a recess 30 which is the lowest point on the inner peripheral side by curving the inner peripheral edge 34 in an arc shape from the lower end part of the vertical part 2 in the standing state. A tip 31 extends upward, and an entrance 32 of the crossbar 6b is provided between the tip 31 and the vertical portion 2, and the crossbar 6b can be hooked in the recess 30. Here, the inner peripheral edge 34 is curved in an arc shape from the lower end portion of the vertical portion 2 with substantially the same width as the width of the strip of the vertical portion 2. In bending, the latching portion 3 immediately projects the bulging portion of the arcuate outer peripheral edge from the lower portion of the vertical portion 2 in the standing state outward in the longitudinal direction of the grip portion 1. The latching portion 3 is cut out obliquely above the annular portion with respect to the vertical portion 2 in the standing state, and is provided in a dominant arc shape larger than half of the entire circumference. An opening width through which the cross bar 6b can enter is secured in the notched opening (advance entrance 32). Note that when the entrance 32 is closed to form a ring, the inner circumferential circle formed by the ring is substantially line symmetric with respect to the vertical center line of the vertical portion 2. The plate thickness t ₁ (thickness) of the latching portion 3 is the same as the thickness of the vertical portion 2.

The auxiliary member 5 is a belt-like body that is curved in an arc shape similar to the hook portion 3. A pin 4 is provided in a portion extending from the latching portion 3 to the vertical portion 2, and an upper end portion of the arc-shaped auxiliary member 5 is rotatably attached to the pin. Then, the auxiliary member 5 is hung by its own weight, and is arranged so as to close the entrance 32 of the latching portion 3 under the standing state of the vertical portion 2. Specifically, a through hole e is formed in a portion from the latching portion 3 to the vertical portion 2, that is, a base portion of the latching portion 3, and a through hole 59 is drilled in the upper end portion of the auxiliary member 5. As shown in FIG. 1, the opening 52 cut out by the arcuate outer peripheral edge of the auxiliary member 5 projecting outward and formed in the arcuate shape is opposed to the entrance 32 of the latching part 3 as shown in FIG. In this manner, the band plate-like plate surface at the upper end portion of the auxiliary member 5 and the plate surface of the latching portion 3 are brought into contact with each other. Then, the through hole e and the through hole 59 are aligned. Thereafter, the pin shaft portion 4b is inserted into the through hole e and the through hole 59, the pin tip portion 41 is crimped, and the auxiliary member 5 is pivotally attached to and integrated with the portion extending from the latching portion 3 to the vertical portion 2. The auxiliary member 5 hangs down under its own weight, closes the entrance 32 and forms the annular hole O with the auxiliary member 5 and the hooking portion 3, and the arc-shaped forming portion of the auxiliary member 5 is the arc-shaped forming portion of the hooking portion 3. Overlap as shown in FIG. Reference numeral 4a denotes a head portion of the pin 4, and reference numeral 41a denotes a caulking portion formed by caulking the tip end portion of the pin.
In this embodiment, as shown in FIGS. 2 and 6, the auxiliary member 5 is curved in an arc shape to form a recess 50 that is the lowest point on the inner peripheral side under the upright state of the vertical portion 2, and further The tip 51 extends upward in the portion 2.

In this way, the handle in which the metal gripping portion 1, the vertical portion 2, and the latching portion 3 are integrated and the metal auxiliary member 5 is rotatably attached by the pin 4 is a groove cover laid in a side groove or the like. Two pieces are prepared for the grating 6. For example, two holding bodies 9 as shown in FIG. 9 are provided in one of the gratings 6 arranged in the side groove, and the gripping portion 1 is fitted to the standing wall portion 92 having elasticity of the holding body 9. Let When the grating 6 is requested to be lifted, the handle is removed from the standing wall. This holding body 9 is a holding body described in Japanese Patent Application Laid-Open No. 2001-115539, and details are omitted. The technical contents described in the publication are described in this specification. Reference numeral 91 denotes a horizontal plate portion, reference numeral 94 denotes a gravel drop hole, reference numeral 97 denotes a reinforcing plate, reference numeral 98 denotes a support plate, reference numeral 99 denotes a rivet, and reference numeral u denotes an encircling recess.
Instead of providing the holding body 9, it can be attached to the grating 6 with a chain with a lock, etc., and can be used by removing the lock when necessary.

  Next, an example of use of the handle having the above configuration will be described. First, the holding part 1 is grasped by hand, and the latching part 3 and the auxiliary member 5 are inserted into the slit ε between the main bars 6a of the grating 6 as shown in FIG. Then, the central portion G of the arcuate outer peripheral edge of the auxiliary member 5 that is suspended by its own weight is pressed against the cross bar 6b that is the hooked member F to be lifted. By this pressing, the auxiliary member 5 rotates around the pin 4 as shown in FIG. 4, and the tip 51 of the auxiliary member 5 hanging down under its own weight is lifted in the direction of the arrow. Thereafter, when the raised tip 51 gets over the cross bar 6b, the auxiliary member 5 rotates once and automatically hangs down. The bar 6b is taken in (FIGS. 5 and 6). After this state is reached, the grip 1 is lifted. Then, the cross bar 6b is hooked on the hook portion 3 and the auxiliary member 5, and the grating 6 is easily lifted. The grating 6 covered with the side groove can be easily lifted and opened.

The handle configured as described above has a thickness obtained by adding the thickness t ₁ of the latching portion 3 and the thickness t ₂ of the auxiliary member 5 in a lattice shape with the main bar 6 a and the cross bar 6 b orthogonal thereto. Since it is smaller than the slit width W between the main bars 6a related to the grating 6, the latching portion 3 and the auxiliary member 5 can be inserted into the slit ε. Since it can be inserted into the slit ε, dust and the like clogged in the slit ε can be easily removed. Then, as described above, it is attached to the grating 6 with a chain with a lock or the like so as to be detachable from the holding body 9 so that it can be separated from the grating 6 so that the handle can be detached from the holding body 9 when necessary. There is no need to bring a handle to the site. By only preparing two pieces, the plurality of gratings 6 covered with the side grooves can be lifted one after another and easily opened. Since the latch part 3 and the auxiliary member 5 are made of a metal plate to ensure the mechanical strength and reduce the thicknesses t ₁ and t ₂ , it is particularly useful as a fine grating handle.

  In addition, the inner peripheral edge 34 of the latching portion 3 is curved in an arc shape from the lower end portion of the vertical portion 2 in the standing state, thereby forming a recess 30 that is the lowest point on the inner peripheral side. The front end 31 extends upward, the entrance 32 of the crossbar 6b is provided between the front end 31 and the vertical portion 2, and the crossbar 6b can be hooked in the recess 30. The grating 6 can be safely lifted in the recess 30. Since the latching portion 3 is provided in a dominant arc shape that is notched for the entrance port 32 with respect to the standing vertical portion 2, the crossbar 6 b can be removed from the entrance port 32 by inserting it into the recess 30. It becomes difficult and safety increases. A pin 4 is provided in a portion extending from the latching portion 3 to the vertical portion 2, and an upper end portion of the arc-shaped auxiliary member 5 is rotatably attached to the pin and integrated, and the auxiliary member 5 has the weight of the vertical portion 2 due to its own weight. Since it arrange | positions so that the entrance 32 of the latching | locking part 3 may be plugged up in the standing state, the cross bar 6b taken in in the ring hole O becomes a structure which cannot come out from the entrance 32, and safety | security increases further. When the auxiliary member 5 is curved in a circular arc shape, a recess 50 which is the lowest point on the inner peripheral side is formed under the standing state of the vertical portion 2, and the tip 51 extends upward in the vertical portion 2. Since the movement of the cross bar 6b that once fits in the recesses 50 and 30 and is hooked and lifted by the latching portion 3 is restricted by the latching portion 3 and the auxiliary member 5, there is no possibility of coming out of the entrance 32. The grating 6 can be lifted safely and reliably using this handle.

Further, since the vertical portion 2 and the latching portion 3 are made of a band plate-like body having the same plate surface, and the plate surface direction of the band plate-like body is made to coincide with the longitudinal direction of the gripping portion 1, the entire handle is It is almost flat and easy to store without taking up space.
Further, since the vertical portion 2 hangs down in a T-shape from the approximate center of the grip portion 1, the grating 6 with the handle held in the hand and the cross bar 6b hooked on the hook portion 3 can be easily lifted. In addition, since the latching portion 3 immediately protrudes from the lower portion of the vertical portion 2 in the standing state to the outside of the grip portion 1 in the longitudinal direction, it is almost directly below the vertical portion 2. The ring hole O can be positioned at the center of the ring hole, the balance when lifting the cross bar 6b disposed in the ring hole is good, and the handle is excellent in handling.
