Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a hook fitting for hanging at high places that can facilitate work at high places.

(Prior art and its problems) Conventionally, when constructing an outdoor structure such as a utility pole, etc., a worker has to climb to a high place to perform the work. There were problems in that it was extremely difficult to climb up to the top, the work time required to reach the high place was extremely long, and the work efficiency was poor.

(Means for Solving the Problems) The present invention has been devised in view of the above-mentioned conventional problems. The purpose is to provide a hook fitting that can be lifted up, and its gist is to provide a hook that has a hanging space that can be hung on wires etc. placed at high places, and a ring part on the lower end to which a rope etc. can be connected. a hook body provided with the hook body; an opening/closing plate pivotally mounted on the hook body so as to be able to open and close the hanging space; and a hanging ring part connected to the opening/closing plate and rotatably abutted on the hook body, When a rod member or the like is hung from below on the hanging ring portion and the hook body is lifted, the opening/closing plate rotates as the hanging ring portion rotates to open the hanging space, and the rod member etc. The opening/closing plate is configured to return to its original position and close the hanging space when it is detached from the hanging ring.

(Function) The hook fitting mainly consists of a hook body, an opening/closing plate, and a hanging ring, and with the rod member hooked to the hanging ring, the rod member can be lifted from the ground to a high place and the entire hook fitting can be lifted. When lifting, the opening/closing plate rotates together with the hanging ring part to open the hanging space of the hook body, so the opened hanging space can be easily used to hang wires etc. placed at high places. can. After that, by pulling down the rod member and separating the rod member from the hanging ring part, the opening/closing plate returns to its original position as the hanging ring rotates, and the opening/closing plate closes the hanging space of the hook body, so the hook metal fitting is firmly held at a high height. As a result, the hook metal fitting will no longer be detached from the wire or the like. In this way, the hook metal fitting can be easily and reliably installed at a high place from the ground via a pole member, etc., and if a rope or the like is connected to the lower end of the hook body of the hook metal fitting, the hook metal fitting can be attached to a wire, etc. When it is latched, a rope or the like is suspended, and the rope or the like allows the user to easily ascend from the ground to a high place, allowing for smooth work at heights. In addition, after the worker descends to the ground via a rope, the rod member is hooked from the ground to the hanging ring and the hanging ring is pushed upward, so that the opening/closing plate is opened as the hanging ring rotates. The hook body can be easily removed from wires etc. in high places.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 shows an overall perspective view of the hook fitting of this example,
The hook fitting 1 is mainly composed of a hook body 2, an opening/closing plate 3, and a hanging ring part 4. The hook body 2 has a plate shape and has a curved lip part 2a at its upper end. A hanging space K inside the lip part 2a.
is formed. Further, a ring ring 6 is provided in a hanging manner at the lower end of the hook body 2 through a fixing pin 5, and a rotating ring 2b is connected to the lower end of the ring ring 6 so as to be rotatable in the horizontal direction. ing.
A rope or the like can be connected within this rotating ring 2b. The lower end of the opening/closing plate 3 is rotatably attached to the hook body 2 via a fulcrum shaft 7, and the upper end thereof is rotatably attached to the hook body 2.
It is located at the lower end of the latching space K, and the latching space K can be opened and closed. A connecting bar 9 is connected to the upper end of the opening/closing plate 3 via a connecting shaft 8, and the lower end of the tilting plate 4b is connected to the end of the connecting bar 9.

The hanging ring portion 4 is installed in a protruding manner on the rear side of the hook body 2 via a protruding rod 4a.
A tilting plate 4b is bent at an angle of about 90 degrees at the end of a.
is provided. The upper end of this tilting plate 4b is rotatably attached via a support shaft 10 to a projecting plate 2c integrally projecting from the hook body 2, and a fitting formed in a concave shape is attached to the lower end of the tilting plate 4b. The connecting bar 9 is fitted into the fitting groove 4c.

Therefore, the hanging ring part 4 can be rotated in the vertical direction via the support shaft 10, and as the hanging ring part 4 is rotated, the tilting plate 4b is rotated in the front-rear direction. The opening/closing plate 3 can be opened and closed in the front and rear directions via the connecting bar 9 to open and close the hanging space K.

A rope 13 is attached to the rotating ring 2b at the lower end of the hook 1 having such a structure as shown in FIG.
In the state where is attached via the binding part 13b,
When the hanging ring part 4 of the hook metal fitting 1 is hooked to the hanging rod 11a provided at the upper end of the extensible installation rod 11 and the installation rod 11 is pushed up from the ground, the hanging rod 11
As a moves upward, the hanging ring part 4 is rotated upward (the hanging ring part 4 easily moves upward by the weight of the hook 1 or by pulling the rope 13 downward), and the hanging ring part 4 is rotated upward. As the tilting plate 4b rotates rearward as the tilting plate 4b rotates, the opening/closing plate 3 is moved rearward via the connecting bar 9, and the locking space K becomes open. In this state, move the installation rod 11 further upwards, lift the entire hook fitting 1 to the position of the hanging wire W stretched between utility poles, and operate the installation rod 11 from the ground to create a space for the hook body 2 to hang. K can be hung on the hanging wire W.

After hooking the hanging space K to the hanging wire W, by moving the installation rod 11 downward from the ground and separating it, the opening/closing plate 3 is moved forward by the return force of a spring (not shown) installed inside the opening/closing plate 3. returned to the side,
The hanging ring portion 4 is returned to the lower side. In this state, the hanging space K is in a closed state, so that the hook fitting 1 is reliably hung on the hanging wire W. When the installed rod 11 is retrieved from the ground, the hanging wire W is attached as shown in Fig. 4.
The hook 1 is securely hooked to the rope 13, and the rope 13 connected to the rotating ring 2b at the lower end is suspended above the ground.

In this state, a worker from the ground can easily ascend to a high place using a predetermined elevating device along the rope 13, and can smoothly perform high-place work. After completing work at high places, the worker can descend to the ground via this rope 13, and then lift the installation rod 11 from the ground again and place the installation rod 1 on the hanging ring part 4.
By hooking the hanging rod 11a of No. 1 and lifting the hanging ring part 4 upward again, the opening/closing plate 3 is rotated rearward and the hanging space K is opened, and in this state, the installation rod 11 is further inserted. When lifted upward, the hanging space K is easily separated from the hanging wire W, and the hook fitting 1 can be recovered to the ground together with the installation rod 11.

If the hook fitting 1 of this example is used in this way,
The hook fitting can be easily installed at a high place using the installation pole 11 etc. from the ground, and the rope 13 etc. can be easily hung vertically through the hook fitting 1,
It is possible to easily ascend to a high place using the rope 13.

Note that the hook fitting 1 of this example is just one example, and the shapes of the hook body 2, opening/closing plate 3, hanging ring part 4, etc. can be changed as appropriate. For example, the hanging ring part 4 may be made of wire rope or the like. It can also be constructed in a more rigid shape. In addition, by using two hook fittings 1 of this example at the same time, it is possible to easily hang a rope ladder or the like on the suspension line W using the pair of hook fittings 1, 1, and it is possible to easily hang a rope ladder or the like on the suspension line W. can easily climb to high places.

In addition, in this example, the suspension wire W stretched between the electric wires
An example of the work of hanging the hook fitting 1 on the top is shown, but
The hook fitting 1 of this example can be easily hung on other protruding members etc. installed at a high place.For example, the hook fitting 1 can be easily hung from the ground on a fitting protruding from a wall surface etc. It can be hung and moved up and down the wall easily.

FIG. 5 shows a second embodiment, in which the hanging space has a large diameter for the purpose of hanging on a larger object, and the hanging ring part 4 is directly in contact with the connecting bar 9, and the hanging ring 4 is in direct contact with the connecting bar 9. Although changing the direction of rotation by the shaft 10 is not used, the desired effect is the same as in the first embodiment. In other words, the connecting bar 9 connected to the protruding rod 4a of the hanging ring part 4 that has been rotated upward by the installation rod 11 comes into contact with the sliding member 12, and the rotational force is still absorbed, so that the connecting bar 9 is rotated upwardly by the roller. The opening/closing plate 3 is urged to rotate about the pivot point 7 of the opening/closing plate 3 while sliding on the sliding member 12. Therefore, the latching space of the hook body is opened and latching is possible. Installation rod 1
1 is lowered and the rotation of the hanging ring portion 4 is returned to its original position, the connecting bar 9 comes into contact with the locking pin 14 at the bottom, and is fitted into the concave locking portion 91 provided on the connecting bar, and the opening/closing plate 3 is placed in the closed position. This prevents opening even if an unexpected external force is applied to the opening/closing plate 3 in the direction of rotation.

(Effects of the Invention) The hook fitting for hanging at high places of the present invention has a locking space that can prevent wires etc. arranged at high places, and is equipped with a rotary ring at the lower end to which a rope etc. can be connected. A hook body, an opening/closing plate pivotally mounted on the hook body so as to be able to open and close the hanging space, and a hanging ring part connected to the opening/closing plate and rotatably protruding from the hook body, When a rod member, etc. is hung from below on the hook body and the hook body is lifted, the opening/closing plate rotates as the hanging ring rotates to open the hanging space, and the rod member, etc. can be lifted from the hanging ring. Since the opening/closing plate is configured so that it can return to its original position and close the hanging space when it is detached, it can be easily hung at a high place from the ground via a pole member, etc., and the hanging state can be maintained. It is possible to reliably move up and down to a high place via a rope or the like hanging from the hook when the hook is in the hooked state, and it has the effect that the work of going up and down to a high place can be done extremely easily.
