Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application field] The present invention relates to a grip mounted on a gutter or the like, and relates to a handle for facilitating attachment / detachment of the grating.

[Background Art] A grating a to be attached to an opening such as a side groove is formed by crossing a connecting rod c between a plurality of long base materials b arranged at appropriate intervals. In the removal work, the conventional
As shown in the figure, using a tool f having a finger hook d at the upper end and a hook-shaped bearing e at the lower end, the bearing e was hooked on the connecting rod c at each side of the grating a. Thereafter, a finger is hooked on the finger hook d and pulled upward to float the grating a.

[Problem to be Solved by the Invention] As described above, the mounting and dismounting operation of the grating a is performed by fitting the hook-shaped bearing portion e of the tool f into the connecting rod c by the tool f and suspending the grating a. After being held, it must be removed from the gutter or the like, and at the time of loading / unloading work, the tool f must be prepared, so that there is a disadvantage that it cannot be opened and closed arbitrarily.

In the present invention, the tool f
It is an object of the present invention to provide a grating a provided with a handle which can easily perform the work of mounting and dismounting the grating a.

Means for Solving the Problems According to the present invention, in a grating constituted by connecting a connecting rod at right angles between a plurality of long base materials arranged at appropriate intervals, the connecting rod is rotatably supported by the connecting rod. A bearing portion to be formed, a rotation pressing portion located immediately above the bearing portion and having a pressing surface near the surface of the grating or less, and an annular finger hanging portion hanging down from the bearing portion. A grip is provided which is changed to an upright position in which the finger hooking portion projects upward from the grating by a pressing operation on the rotation pressing portion.

[Operation] In the case of mounting and dismounting the grating, the rotation pressing portion is pressed downward from the surface of the grating, and the handle is turned about 180 ° with the connecting rod as a support shaft, and the finger hook portion is turned. It is in a standing state protruding upward. Then, by putting a finger on the finger hook and pulling the finger, the grating is lifted upward from a side groove or the like and becomes movable.

Further, in a state where the finger is separated from the finger hook, the finger hangs down due to the weight of the finger hook, and the grip does not protrude from the surface of the grating. The rotation pressing portion is positioned and supported near the surface or below.

The same applies to the case where grating is applied to the opening such as the side groove.

[Embodiment] An embodiment of the present invention will be described with reference to FIGS. 1 to 3.

FIG. 2 shows a rectangular grating 1 attached to the opening of the gutter, in which a plurality of long base materials 2a are juxtaposed at equal intervals, and end long base materials 2b, 2b are arranged at both ends thereof. And each long base material 2a,
The connecting rods 3 are connected by orthogonally inserting the connecting rods 3 into the insertion holes 4 formed in the respective holes 2b, and the long side substrates 2b and 2c are joined to the left and right ends thereof.

At both sides of the grating 1, a handle 10 according to a main part of the present invention is fitted on the connecting rod 3. The handle 10 is provided for attaching and detaching the grating 1 from a side groove or the like, and the details will be described in detail with reference to FIGS.

The handle 10 includes a substantially U-shaped bearing portion 11 rotatably fitted to the connecting rod 3 in the grating 1, and is curved from the upper end of the bearing portion 11 to form a smooth pressing surface. The rotation pressing portion 13 to be 12 is extended, and in its attached state,
The pressing surface 12 is located near the surface of the grating 1 or lower. The pressing surface 12 of the rotation pressing portion 13 has a length extending to both sides from the fulcrum of the bearing portion 11.

Further, a ring-shaped finger portion 15 having a circular shape is formed below the bearing portion 11 via a connecting portion 14 and is suspended from the connecting rod 3 in the attached state. The finger hook
At one end of 15, the non-slip parts 16, 16 project in both directions,
The non-slip portions 16, 16 lock both fingers and prevent them from falling off, so that the finger hook 15 can be securely gripped. The finger hooks 15 are formed of long base materials 2a and 2b as described later.
By pressing the rotation pressing portion 11 from above between,
It will project upward from grating 1.

 Next, an operation method of the handle 10 will be described.

First, as shown in FIG. 3, by pressing from below the rotary pressing surface 12 of the handle 10 supported by the connecting rod 3 in the rectangular grating 1 from below as shown by the right or left arrow.
The bearing 11 rotates 180 ° outward with the connecting rod 3 as a support shaft. As a result, as shown by the chain line in FIG. 3, the ring-shaped finger hook 15 formed below the bearing 11 and having an oval shape becomes an upright state on the grating 1, and the finger hook 15 of the handle 10 is formed.
Then, the grating 1 is pulled by pulling the grating 1 to remove the grating 1 from a side groove or the like. At this time, both fingers are locked by the non-slip portions 16, 16 as described above, thereby preventing falling off.

Further, the same procedure is applied to the case of attaching to an opening such as a side groove.

Further, in the above-described embodiment, the shape of the finger hook 15 is shown only in a substantially annular shape. However, it is substantially T-shaped, L-shaped, rectangular or square having an opening, and various other shapes. The handle 6 is constituted as long as a finger hook 15 provided at the lower end of the rotation pressing portion 13 is provided at an upright position protruding upward from the grating 1. What you get.

Further, in the above-described configuration, a substantially U-shaped bearing portion 11 is provided so that the bearing portion 11 can be detachably supported on the connecting rod 3, thereby facilitating the attachment and the handle. If the 10 is damaged, it can be easily replaced.

Further, in the above-described configuration, the one in which the handle 10 is applied to the grating 1 composed of one connecting rod 3 is shown, but the present invention can naturally be applied to the one using a plurality of connecting rods 3. In the case of using two connecting rods 3, for example, the grip 10 is attached at diagonal positions on both sides of the grating 1 so that the lifting operation can be performed stably.

[Effects of the Invention] As described above, the present invention supports the bearing of the handle by the connecting rod in the rectangular grating so as to be rotatable, and applies an external force to the pressing surface of the handle. Since the finger hook portion supported by the connecting rod in the grating is made to stand on the grating surface, it can be converted to an upright state and transported as necessary.
There is no need to separately prepare tools during work as in the past,
The loading / unloading operation can be performed easily and arbitrarily, and furthermore, there is an excellent effect that the operation time can be shortened because the locking operation of the tool is not required.
