Description

  The present invention is a joining / removing device for two joining tools.

  For forestry, as shown in FIG. 1, two chairs and wires are joined by holding the trunk with two joining and removing devices, and two footrests and wires are joined by holding the trunk with two joining and removing devices. There is a pruning climbing machine (hereinafter called a climbing machine) that climbs up and down straight trunk trees like a worm. The joining / removing device consists of a tubular joint that has several holes for passing a metal rod for joining in a tube connected to a chair, etc., and a cover tube that has one hole for passing a metal rod for joining connected to a wire. It consists of a connector and a metal rod for connection and a safety pin. There are four sets of joining / removing devices on the left and right sides of the chair and two sets on the left and right sides of the footrest. Normally, the upper and lower two pairs on the left side fix the cover tube joint to the center hole of the tubular connector, and the right and two upper and lower sets of joints are attached to and removed from the trunk according to the thickness of the trunk. All four pairs must be detached.

  The case of normal desorption with only two sets on the right side will be described. First, when releasing the joint, hold the chair and the footrest on the right side, put it on the right knee, extend both hands to the right side of the trunk, remove the safety pin with the right hand, pull out the metal rod for joining with the left hand, Pull out the cover tube connector that is connected to the wire, release the connection, and then insert a safety pin through the metal rod for bonding into the hole of the cover tube. Do the same with the other pair, then turn the left hand to the left side of the trunk, hold the two wires, remove the wires from the trunk, and move with the right hand holding the chair and the footrest. At this time, if the metal rod for joining is moved to the cover tube without being set, the metal rod for joining is connected to the wire with a thread, but the thread hits a shrub or the like and is lost all day. In addition, the two safety pins must be put in and out of the pocket, which is very troublesome.

  After moving, holding the chair and footrest with your right hand and putting it on the right knee, hold the two wires with your left hand and hold it on the trunk, catch the two cover tube joints attached to the tip of the wire with your right hand, and the left hand as well Extend the cover to the right side and grasp the cover tube connector, remove the safety pin with your right hand, and pull out the metal rod for joining with your left hand. Put the cover tube connector over the tube connector and set the safety pin through the metal rod for bonding in the hole that matches the thickness of the trunk. Similarly, another set of joining / removing devices is set, and the setting is completed.

  As described above, the attachment / detachment of the connector accompanying the movement is very laborious and time consuming and complicated, and the body and mind are tired in places other than the original pruning operation. Although it is troublesome just to insert the safety pin into the hole (the hole is often not seen from diagonally above), one or 20% of the whole forest has particularly thick or thin trees, and these four sets must be attached and detached. In any case, it is in a state that is troublesome anyway.

  When a metal rod for joining is put in and taken out from each hole of the two joints, it can be safely and securely detached with one hand, and at the same time, the metal rod for joining can be prevented from being lost during removal or movement. A joining / removing device is provided.

  The present invention makes it possible to easily attach and detach the climber and the like in a short time with one hand, and not only prevents the loss of the metal bar for joining, but also has the following effects. When the waist height diameter is about 25 centimeters or more, the diameter becomes small at a high place, the wire becomes loose, the chair faces upward, and the work becomes difficult. While climbing, hold the trunk with the left shoulder and left cheek while standing on the footrest, free the chair joint set and hold it with the left hand, and make the chair and wire ring small with the right hand, Set the chair in a position that matches the thickness of the chair and level the chair. At this time, keep the lifeline short for safety. As a result, it is possible to use a climbing machine having a maximum usable waist diameter of about 30 cm at maximum, about 50 cm by extending the cylinder and wire of the cylindrical connector.

  A joining / removing device in which a joining metal rod is taken in and out of each hole of the two joining tools is installed on one joining tool. At this time, the joining metal rod is housed in a cylindrical tube, and a spring or the like is set on the push button extended from the joining metal rod so that the force in the direction in which the joining metal rod is always removed works. Add a device that can be moved with one thumb along the groove of the guide and can be fixed safely in the fixed groove. Similarly, this device can be easily operated by reverse operation, and can be easily detached with one hand. In addition, even when the metal rod is removed at the same time, the joining metal rod is held at one end in the cylinder by a spring or the like and plays a role of preventing loss.

  An embodiment will be described below with reference to FIG. 2 of the accompanying drawings. FIG. 2 shows a case where the tubular joint is covered with a cover tubular joint, and the position of the hole of the tubular joint and the tip of the metal rod for joining is confirmed at 13 peep holes when the thickness of the trunk is reached. Push down the push button with your thumb and hang the push button in the 12 fixed grooves.

To release the set, push down the push button with the thumb of the right hand, remove the push button from the 12 fixing grooves and remove the thumb. At this time, the joining metal rod is held at the upper part of the cylinder by a spring 8 or the like. Remove the cover tube joint with your right hand, hold the two wires with your left hand, remove the wires from the trunk and move with your right hand holding the chair and footrest.

  As described in the previous two paragraphs, desorption is very simple, and at the same time, metal rods can be maintained during movement.

  With this device, the joining position can be changed while climbing the tree in the latter half of the [0007] section, and a climbing machine that can be used for large-diameter trees can also be obtained. In addition, although it would not be thought of by common sense, even in the forest work, even a saw of about 30 centimeters is often not found no matter how much you search. As an example of the loss prevention measure, the pulley of FIG. 3 with the device of the present invention is shown. The metal rods for joining are fully maintained and can be removed and attached almost at once. A pulley with this device is useful for pulleys that frequently change wires during work. In addition, it is recommended to attach the desorption device of the present invention to a machine that is also frequently desorbed during work.

It is a joining / removing device figure which joins a conventional chair and a wire by holding a trunk with two joining / removing devices. It is the figure which attached the joining and removing apparatus of this invention to the joining tool. It is the figure which attached the joining and removing apparatus of this invention to the pulley.
