Description

[Technical field]

[0001] The present invention relates to a tool for guiding objects while avoiding linear obstacles, and in particular to a tool for wiring objects such as cables, call lines, and flexible electric wire pipes between the reinforcing bars (reinforcing bars) installed in the construction of buildings, etc., and a method for avoiding linear obstacles using the tool. [Background technology]

[0002] Generally, when wiring cables in a building construction project, the work is done by wiring the cables in the gap between the rebars and the concrete floor, with the rebars already laid on the floor. This wiring work requires wiring in narrow gaps while avoiding the rebars, so workers have to bend down to wire the cables, or push one end of a long cable into the gap while avoiding obstacles, which is very tedious and hard work. If the cable is heavy and difficult to handle, it is common to wire a lightweight wire-like wiring guide in advance, tie the cable to one end, and pull the other end to wire the cable.

[0003] In addition, although it is different from reinforcement, devices such as those in Patent Documents 1 and 2 have been developed as tools for wiring additional cables while avoiding linear obstacles such as bundling hangers that have already been laid overhead, such as electric wires, and cable racks installed in the ceiling of a building.

[0004] The invention of Patent Document 1 is a wire pulling tool for passing a new cable through a bundling hanger that is wound in a spiral shape or the like around a support wire in order to bundle overhead cables, and has a towing part that engages with the tip of each columnar member of the rotary part so as to be able to swing freely, and an operator attaches a new cable or string to the rear end of the towing part and operates the operating rod to insert the towing part into the bundling hanger and operate the operating rod so that the wire pulling tool faces in a predetermined direction, whereby the bundling hanger enters from an entrance between the holding part and the towing part and exits from an exit between the holding part and the towing part as the rotary part rotates, and the towing part moves in a predetermined direction within the bundling hanger, and is characterized in that a sweeping fin is provided at the front lower part of the towing part to sweep aside cables already laid in the bundling hanger so that the cables do not get tangled between the holding part and the towing part as the towing part moves in the predetermined direction.

[0005] Furthermore, the wiring device of Patent Document 2 is a wiring device mainly for wiring linear members such as cables on a cable rack installed on the ceiling inside a building, and the main body has two members connected at a distance via at least three tiltable connecting bodies, and the connecting body is rotatably attached to one of the two members and has protrusions protruding on both sides at its tip and is movable between a release position where it tilts and releases the connection when an obstructing member that is an obstructing factor when the main body moves passes between the two members and comes into contact with them, and a connecting position where the two members are connected, and the protrusions engage with slits formed on the other of the two members to maintain the connected state, and this wiring device is characterized in that when one connecting body is released due to contact with the obstructing member, the connected state is maintained by the at least two connecting bodies.

[0006] [Patent Document 1] JP 2018-46739 A [Patent Document 2] Patent No. 6785128 Summary of the Invention [Problem to be solved by the invention]

[0007] Wiring cables during building construction is extremely hard work, even with the use of wiring guides, and with the current booming construction boom, there is an urgent need to reduce the burden on workers.

[0008] In addition, although the devices described in Patent Documents 1 and 2 are very useful for specific usage, they are virtually non-versatile, and the devices themselves are relatively large and complex, making them difficult to handle, and since the work is done in the air, the large structure and weight of the devices may be a burden for the workers.In addition, since the devices are large, it is assumed that in many cases it is difficult to carry out wiring work while avoiding the reinforcing bars (reinforcing bars) that are installed in the construction of buildings and other structures where the space available for wiring is limited.

This linear obstacle avoidance method is characterized in that a first action in which the lock plate of a first driving unit abuts against the linear obstacle and a predetermined force is applied, the lock is released and the arm begins to rotate, and then the lock plate abuts against the arm and rotates, thereby passing through the linear obstacle; and a second action in which, when the first driving unit has completed passing through, the first driving unit rotates to an initial position and the other end of the arm is connected to the guidance plate by a magnetic force, and the second and subsequent driving units repeat the first and second actions to pass through the linear obstacle. Effect of the Invention

[0014] The guide object guiding tool of the present invention is very simple and can greatly reduce the burden on the worker because it can route guide objects while avoiding obstacles by simply passing linear obstacles such as reinforcing bars in order, and because the configuration is not complicated, the size of the tool can be made very light and compact, and cables, call lines, flexible electric wire pipes, etc. can be routed between the reinforcing bars and the floor while avoiding reinforcing bars in a narrow space.

[0017] 1 to 3 are overall views of one embodiment of the guide object guiding tool 100 of the present invention, which is composed of a main body case 10 having a substantially U-shaped cross section, a driving unit 20 having an arm 21 and a lock plate 22 that are rotatably attached to the main body case 10 and through which a linear obstacle A passes, and a guide plate 30 to which a guide object B is attached and which is connected by the magnetic force of a magnet 32 ​​when a connecting part 21b that is the other end of the arm 21 is rotated to a predetermined position, and in this embodiment, four driving units 20 are arranged. Note that the number of driving units 20 can be changed according to the shape of the linear obstacle A and the pitch at which they are arranged, so long as it is three or more.

[0018] As shown in Fig. 4, the main body case 10 is mainly composed of a case 11 with a U-shaped channel structure in cross section, and a handle 12. A driving unit 20 is rotatably attached to an arm rotation shaft 11a inside the case 11. Also, a rod-shaped locking unit 11b is attached for locking a lock plate 22. Furthermore, a stopper 11c is attached to maintain the initial position of the driving unit 20, preventing reverse rotation from the initial position.

[0019] The driving unit 20 is composed of an arm 21 and a lock plate 22 as shown in FIG. 5. The arm 21 is in the shape of a letter V when viewed from the front as shown in FIG. 5(a), and is arranged with its long side vertical as its initial position. A rotating shaft 21a is provided on the short side, which serves as the central axis of rotation. A connecting part 21b is provided on the end of the long side of the arm 21 for connecting with the guide plate 30. The connecting part 21b is made of magnetic metal. A spring 23 is attached to the end of the short side of the arm 21, which biases the arm 21 toward the initial position, clockwise as shown in FIG. 5(a). This allows the arm 21 to quickly return to the initial position after passing through the linear obstacle A. A stopper 11c is provided, so that when the arm 21 rotates to the initial position, it hits the stopper 11c and stops.

[0020] The lock plate 22 of the drive unit 20 is rotatably attached by a rotation shaft 22a provided on the crest of the V-shape of the arm 21. The initial position is the vertical state as shown in FIG. 5(a). The upper end of the lock plate 22 abuts against the lock portion 11b as shown in FIG. 5(a) and is structured so that it will come off when a certain force is applied. In addition, a spring 24 is attached as shown in FIG. 5(g) and biases the lock plate 22 toward the initial position, that is, clockwise as shown in FIG. 5(g). This allows the lock plate 22 to quickly return to the initial position after passing through the linear obstacle A.

[0021] The operation of the drive unit 20 is as follows: first, when the linear obstacle A comes into contact with the lock plate 22 and a certain force is applied, the lock is released and the drive unit 20 starts to rotate, then the linear obstacle A comes into contact with the arm 21 and rotates together with the lock plate 22, rotating counterclockwise as shown in Fig. 5(a). Once the obstacle A has passed through, it returns to its initial position. It is designed to return to its initial position more reliably by spring bias.

[0022] The guide plate 30 has a structure in which a plate-shaped guide plate frame 31 sandwiches a cylindrical magnet 32. In addition, a towing part 33 for attaching a guide object B is provided at the rear end in the traveling direction. In this embodiment, since the tool is provided with four drive units 20, the number of magnets 32 used for connection is also four to correspond to the number of drive units 20. The guide plate frame 31 has a connecting part 31a shaped to hook the connecting part 21b of the arm 21 like a hook. In addition, the magnet 32 ​​is arranged at a position where the drive unit 20 is connected by the magnetic force of the magnet 32 ​​when the drive unit 20 is in the initial position. The structure in which the drive unit 20 is connected by magnetic force has the advantage that the separation and connection with the drive unit 20 when passing through a linear obstacle A can be performed reliably with a simple structure.

[0023] The method of the guide object guiding tool 100 to guide the guide object B while avoiding the linear obstacle A is shown in Figures 7 and 8. In the first operation, when the lock plate 22 of the first driving part 20 abuts against the linear obstacle A and a predetermined force is applied, the lock is released and the tool starts to rotate, and then the tool abuts against the arm 21, which rotates and passes through the linear obstacle A. In the second operation, when the passage of the first driving unit 20 is completed, the first driving unit 20 rotates to the initial position and the other end of the arm 21 is connected to the guide plate 30 by the magnetic force of the magnet 32 ​​. The second and subsequent driving units 20 repeat the above first and second operations, thereby towing and positioning the guide object B while avoiding the linear obstacle A. [Industrial Applicability]

[0024] The guide object guidance tool 100 of the present invention is a tool for placing guide objects while avoiding linear obstacles such as reinforcing bars placed mainly near the floor surface, but is also a tool that can tow and guide guide objects while avoiding linear obstacles such as overhead wires or linear obstacles placed on wall surfaces.
