Description

The present invention relates to a container hook rod for obtaining a container placed at a high place or a remote place, and a method of using the same.

Conventionally, in general households, it is common to use a stepladder or a stepladder to obtain a container placed at a high place, and to use a magic hand at a remote place.

Publication No. 6781966

In the above-mentioned conventional method, there is a possibility of falling when using a stepladder or a stepladder, which is dangerous. And it is inconvenient because it may not be possible to stably install the step ladder or stepladder in a narrow place. In addition, it was impossible for wheelchair users and people with disabilities to use stepladders and stepladders on their own.

Also, there are few magic hands that can handle objects placed in high places, and when placed in a distant place, the magic hand directly grabs the object, so the shape of the object is limited and delicate. Objects sometimes spoiled the shape. The technique described in Patent Document 1 is a hook rod for solving this problem, in which the rotational operation of the operating lever at hand is converted into a linear movement of the transmission rod forward and backward by the spiral movement of the male screw rod, and the hook is connected. Since it is possible to incline the claw part of the part, it is possible not only to finely adjust the inclination of the claw part of the hook part but also to fix it by operating the operation lever. With this, if you want to fine-tune the angle of the claw part due to the difference in the weight and shape of the container, you need to not only adjust the rotation of the operation lever at hand, but also fix or release it like the hand angle adjustment function. It is a hook rod that simplifies the operation because it disappears, but there was an inconvenience because the length of the handle part could not be adjusted because it was directly connected to the hand operation part and the claw part of the hook part was movable.

The present invention was invented to solve the above-mentioned problems, and the problem to be solved by the present invention is a container in a remote place without getting on a stepladder or a stepladder and without using a magic hand. It is possible to obtain and place the ladder with a simpler mechanism.

In the present invention, in order to achieve the above object, a worm base is installed between the hook portion having a pair of claw portions facing each other through the gap of the hook rod and the hook portion and the tubular handle portion. A worm gear that is connected and is rotatable around the axis of the handle is provided in the worm base, and an operation lever is provided at the base end of the handle so that the worm gear can be rotated. The operation lever and the worm gear were connected by a transmission rod through the inside of the handle so that the worm gear could be rotated by the rotation operation of the operation lever. In addition, the worm gear and the worm wheel are engaged and connected so as to rotate in a direction different from the axial rotation of the handle of the worm gear in the worm base, and the rotation of the worm wheel is directly reflected on the hook portion. When the worm wheel rotates, the hook portion is tilted with respect to the worm base. Therefore, the rotation operation of the operation lever rotates the worm gear via the operation rod, and the worm wheel that is engaged and connected is rotated so that the claw portion of the hook portion can be tilted. With this, in order to adjust the angle of the hook part with respect to the axis, the inclination of the hook part can be adjusted only by rotating the operation lever, and it is possible to obtain a container placed in a distant place or a narrow place. ..

By installing a worm base between the hook part and the handle part, the rotation operation of the operation lever rotates the worm gear via the transmission rod, and the worm wheel that is engaged and connected also rotates, and the worm wheel Since the rotation can be reflected on the claw of the hook portion to which the rotation is connected and tilted, the transmission rod need only transmit the rotation of the operation lever. As a result, the transmission rod is divided into two parts, which are composed of the first member and the second member and are connected together so that the rotation of the operation lever is transmitted to the worm gear even if the length of the transmission rod is changed. The length of the handle can be adjusted by dividing the handle into two parts and engaging and connecting them, and by providing a fixing device that can be stopped according to the expansion and contraction at the part where the handle is connected and connected. Can be expanded and contracted. In addition, as for the transmission rod, the first member and the second member can move with each other in the axial direction, and the length of the transmission rod is the same when the length of the handle changes by engaging so that the rotation around the axis is transmitted to each other. However, the rotation can be transmitted to the worm gear. Then, by rotating the worm wheel that is engaged and connected, it is possible to incline the angle of the hooking portion. As a result, the length of the hook rod is made into a stretchable hook rod, so not only the range of acquisition of the container placed in a distant place is widened, but also the handle part of the hook rod can be shortened so that it can be carried. We have made it possible to provide a hooking rod that is convenient and closely related to daily life.

When you want to change the angle of the hooking part greatly, you need a lot of rotation speed of the operation lever, but you can adjust the rotation speed by adjusting the width of the worm gear module. In addition, even when the number of rotations is required, a lever is attached so that the rotation operation can be performed with a finger without grasping the operation lever, so that the rotation operation of the operation lever can be easily performed. That is, the operating lever has a shaft portion that rotates together with the transmission rod and a handle that projects in a direction perpendicular to the axial direction from the shaft portion.

If the handle of the hook rod is movable, insert the edge of the container into the gap between the pair of claws of the hook to bring the claw into close contact with the inside of the upper part of the container, and use the other claw of the container. By bringing the handle into close contact with the outer surface of the container and pushing the handle toward the container, the inner claws of the container tilt the container toward you and the claws on the outer surface of the container push the container to the opposite side. Lift the container in the state, and the container will not fall from the hook.

If the handle cannot be moved, rotate the operation lever to adjust the inclination of the hook, and after inserting the edge of the container into the gap between the pair of claws of the hook, By tilting the hooking part by operating the operation lever and crimping the claw part of the hooking part to the inner surface of the upper part of the container and the side surface of the lower part of the container, the container can be obtained without falling from the claw part even if the container is lifted. ..

If you want to install the container in a remote place, insert the edge of the container into the gap between the pair of claws of the hook, and tilt the hook so that the hook presses against the side of the container. , The container can be installed in a remote place. Further, after installing the container, the claw portion can be removed from the container by crimping to the side surface of the container and moving the handle portion so as to remove the claw portion. However, if the handle cannot be moved, the tilt of the hook can be adjusted by adjusting the rotation of the operating lever, and the claws crimped to the side of the container can be removed from the container, so install the container in a narrow space. Is possible.

According to the present invention, containers placed in various places can be obtained with a hook rod. Also, even if the container can be installed in a place where it can be obtained for a healthy person, even if there is an obstacle for a person with a wheelchair or a foot disorder, or if it is too narrow to approach the container, from a remote location. You will be able to obtain the container or move it to another location. Also, since the angle of the hook can be adjusted only by rotating the operation lever, the angle can be adjusted and fixed at the same time, so the structure is simpler and the length of the handle can also be adjusted. Not only is it possible to obtain a wider range of places, but it is also convenient to carry and has been made into a hook rod that is closely related to daily life.

It is sectional drawing which installed the worm base between the hook part and the handle part. Sectional drawing of the connection between the worm gear in the worm base and the transmission rod between the hook part and the handle part. It is an internal view of the connection part of the transmission rod and the operation lever of a handle part.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 5 is a cross-sectional view of the hooked portion according to the embodiment of the present invention. In this hook rod, a worm base 3 is installed between a hook portion 1 having a pair of claw portions 1a and a claw portion 1b and a tubular handle portion 4a, and the worm base 3 has a handle portion connected to each other. A worm gear 3a that can rotate around the axes of 4a and 4b is provided, an operation lever 7 is installed at the base end of the handle 4b, and the rotation operation of the operation lever 7 is linked to the worm gear 3a on the operation lever 7. It was connected by the transmission rods 5 and 6 which were connected together as described above. Now the operating lever 7 can rotate the worm gear 3a. Further, in the worm base 3, a worm wheel 3b that rotates about an axis in a direction different from the axis of the handle portions 4a and 4b that are connected to each other is engaged and connected to the worm gear 3a. The axis of rotation of the worm wheel 3b and the axes of the handles 4a and 4b are perpendicular to each other. The worm gear 3a and the worm wheel 3b are rotatably attached to the worm base 3. The connection portion 2 of the hook portion 1 is attached to the worm wheel 3b. The connection portion 2 also rotates with the rotation of the worm wheel 3b, and the hook portion 1 is tilted with respect to the worm base 3, that is, the handle portions 4a and 4b due to the rotation of the connection portion 2. As a result, the rotation operation of the operation lever 7 rotates the worm gear 3a via the operating rods 5 and 6 connected in a container, and the rotation of the worm gear 3a converts the worm wheel 3b that is engaged and connected to rotate. By moving, the rotation of the worm wheel 3b led to the inclination of the hook portion 1, and the claw portion 1a and the claw portion 1b could be inclined and crimped to the side surface of the container so that the container could be obtained (Fig.). See 5, 6 and 7).

1 and 2 are schematic views of a hook rod according to an embodiment of the present invention. For this hook rod, a worm base 3 is installed between the hook portion 1 and the tubular handle portion 4a, and the worm base 3 can be rotated around the axes of the handle portions 4a and 4b connected together. The worm gear 3a is provided, the operation lever 7 is provided at the base end of the handle 4b, and the operation lever 7 is connected to the transmission rods 5 and 6 so as to transmit the rotation of the operation lever 7 to the worm gear 3a. The worm gear 3a and the operation lever 7 were connected at. The transmission rod is divided into a transmission rod (first member) 5 and a transmission rod (second member) 6 and combined with each other so that rotation can be transmitted. For example, the first member and the second member have a shape in which they are caught by each other when they try to rotate about the axis in a cross section perpendicular to the axis. Then, the handle portion 4a and the shape portion 4b are also divided into two parts and connected to each other so that the length of the handle portion can be expanded and contracted, and the length of the handle portion can be fixed to the portion connected to the handle portion. By providing 4c, the length of 4a of the handle and 4b of the handle can be adjusted and fixed. The fixing device 4c is a device that switches between a state in which the phase movement in the axial direction of the handle portions 4a and 4b is possible and a state in which the phase movement is not possible. The fixing device 4c may be, for example, a pin or screw perpendicular to the axis, or one that is released by rotation around the axis. Further, the transmission rod 5 (first member) and the transmission rod 6 (second member) are divided into two parts so that they can move to each other in the axial direction, and the rotation around the axis is transmitted so as to be transmitted. The length of part 4b is the same and the rotation can be transmitted. Therefore, the length of the handle 4a and the handle 4b can be adjusted, the range of acquisition of the container placed in a remote place is expanded, and it is convenient to carry the hook rod (Figs. 1 and 2). reference).

As shown in FIG. 7, an operation lever 7 is provided at the base end portion of the handle portion 4b, and the operation lever 7 is freely rotatable and connected to the handle portion 4b by the connection portion 8. The connecting portion 8 is composed of a groove extending in the circumferential direction of the outer peripheral surface of the handle portion 4b and a protrusion of the operating lever 7 that fits in the groove. As a result, the operating lever 7 can rotate in the circumferential direction with respect to the handle portion 4b and is fixed in the axial direction. A transmission rod 6 (second member) is connected to the operation lever 7, and the transmission rod 6 (second member) transmits the rotation operation of the operation lever 7 and is connected to the transmission rod 6 (second member) in combination. By connecting to the transmission rod 5 (first member), the rotation is transmitted to the worm gear 3a in the worm base 3 installed at the connection portion between the handle portion 4a and the hook portion 1, and the worm gear 3a is engaged and connected. The worm wheel 3b is rotated. Therefore, it is possible to obtain the claw portion 1a and the claw portion 1b by tilting the container, which is connected to the tilt of the hook portion 1 only by rotating the operation lever 7. The operating lever is also provided with a lever handle 9 so that it can be operated without gripping the operating lever (see FIGS. 7, 1 and 2).

FIG. 3 shows the case where the container is placed in a parallel or high place. In this case, the claw portion 1a of the hook portion 1 is placed inside the upper part of the container, and the claw portion 1b is placed on the outer surface of the container. By pushing the handle portions 4a and 4b toward the container side, the claw portion 1a tilts the container toward you and the claw portion 1b pushes the container to the opposite side. By doing so, the claws 1a and the claws 1b exert opposite forces on the container, the claws 1a are in close contact with the inner surface of the container, and the claws 1b are in close contact with the outer surface of the container. When the container is lifted, the weight of the container is applied to the claw portion 1b, and a force acts on the upper claw portion 1a in the direction opposite to that of the claw portion 1b. Therefore, the outer surface of the container is crimped to the pair of claws 1a and 1b, and the container can be obtained without dropping.

FIG. 4 shows a case where the container is placed in a parallel or high and low place, and the claw portion 1b of the hook portion 1 is brought into close contact with the upper inner side of the container and the claw portion 1a is brought into close contact with the outer surface of the container. After that, by separating the handle portions 4a and 4b from the container, the claw portion 1b tilts the container toward you and the claw portion 1a pushes the container to the opposite side. By doing so, the claws 1a and the claws 1b exert opposite forces on the container, the claws 1b are in close contact with the inner surface of the container, and the claws 1a are in close contact with the outer surface of the container. When the container is lifted, the weight of the container is applied to the claw portion 1a, and a force acts on the claw portion 1b in the direction opposite to that of the claw portion 1a. Therefore, the outer surface of the container is crimped to the pair of claws 1a and 1b, and the container can be obtained without dropping.

However, depending on the position of the container, it may be difficult to insert the claw portion 1a and claw portion 1b of the hook portion 1 into the edge of the container to be obtained. After inserting the pair of claws 1a and 1b into the edge of the container by the operation of 7, the container is further tilted by the operation lever 7 and the claw 1a and the claw 1b are crimped to the edge of the container. It made it possible to obtain it without coming off the claws.

In addition to obtaining the container, after inserting the edge of the container at hand into the gap between the claw portion 1a and the claw portion 1b of the hook portion 1, the handle portion 4a, so that the container is crimped to the claw portion 1a and the claw portion 1b. If the container is crimped to the claw portion 1a and the claw portion 1b by moving 4b so that the container does not fall from the claw portion 1a and the claw portion 1b, the container can be installed in a remote place. In addition, even if it is difficult to move the handle after placing the container, the pair of claws 1a and 1b can be removed from the container by rotating the operation lever 7 to change the inclination of the hook 1. did.

This hook rod can be obtained by hooking the edge of the container on a pair of facing claws 1a and 1b and crimping the container to the claw 1a and 1b using the weight of the container. .. Therefore, this hook rod can be obtained not only as a container but also as an object as long as it is a container that can be hooked on the claw portion 1a and the claw portion 1b. In addition, since this hook rod obtains a container by crimping the claw portion 1a and the claw portion 1b to the edge of the container, even if it is a delicate object that cannot be grasped, the object is stored in the container. Objects can be obtained if possible. Further, the container may be strong enough to withstand the weight of the object stored in the container on the outer surface of the container when the edge of the container is caught on the claw portion 1a and the claw portion 1b and the container is lifted. Further, as for the shape of the container, a wide variety of materials and shapes are good as long as the container can be hooked on the claw portion 1a and the claw portion 1b at the edge. You can just get the container, but if the container is made of a slippery material, it seems that using a non-slip material for the surface of the claw part 1a and the claw part 1b will lead to safer acquisition.
