Description

[Technical Field]

[0001] The present disclosure relates to tools and strapping machines. [Background technology]

[0002] Some tools, such as rebar tying machines, nail guns, and screw drivers, have hooks attached to the tool body or grip. These hooks are intended to be attached to the belt of a worker's trousers when the tool is not in use or when the tool is being carried, or to be attached to scaffolding or a stepladder placed on the work site when the tool is not in use.

[0003] For example, Patent Document 1 describes a screw driver in which a pair of upper and lower insertion holes are opened and formed on the side of the head, and a hook device is attached to the insertion holes. Patent Document 2 describes a driving tool in which a hook support member is fixed to the rear of a grip formed at one end of the body, and a hook is attached to this hook support member, with the hook portion and slide shaft portion connected in a bent shape.

[0004] Incidentally, at work sites where, for example, rebar placement work, where rebar is placed in walls or columns, and bundling work, where the placed rebar is bound with wire, is performed alternately, the tool (rebar binding machine) is often hung on the worker's belt or placed on scaffolding during the rebar placement work. However, rather than hanging the tool on a belt or placing it on scaffolding, hanging the tool on the placed rebar allows the next work (binding work) to be carried out more smoothly, which is advantageous in terms of work efficiency. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-150503 [Patent Document 2] Patent No. 4877488 Summary of the Invention [Problem to be solved by the invention]

[0006] However, when the hook is attached to the side of the main body so that the opening of the hook faces forward (of the main body), as in the tool disclosed in Patent Document 1, there is a problem that when the tool is hooked onto a rebar or the like with the hook opening oriented in the direction and then released, the tool tilts significantly, becomes unstable, and is prone to falling off the rebar. Also, because the tool tilts (moves) significantly when released, there are problems such as the tool easily coming into contact with surrounding rebar or the tool itself, damaging the surrounding rebar or the tool itself.

[0007] Furthermore, the tool disclosed in Patent Document 2 has a hook on the lower side of the grip, which means that when hooking the hook onto rebar, a stepladder, etc., the worker must turn his wrist to hook it, making it difficult to hook and preventing the worker from quickly moving on to the next task.

[0008] The present invention solves the above-mentioned problems and aims to provide a tool and binding machine that can be easily hooked onto a target object such as reinforcing bars at a work site, and that does not tilt significantly when hooked. [Means for solving the problem]

[Effects of the Invention]

[0013] According to the tool of the present disclosure, the first hook attachment portion is attached so that the hook is on the upper surface of the main body portion and the opening of the hook faces forward, so that when the hook attached to the first hook attachment portion is hooked onto a target object such as a rebar, wall, or pillar located in front of the worker, the worker can hook the hook with a small movement by tilting the front end of the main body portion where the output portion is located downward, without having to turn the wrist over. Therefore, when the hooking operation is repeated when the tool is in use and when it is not in use, work efficiency is improved and the workload on the worker is reduced. Furthermore, the second hook mounting portion mounts the hook to the side of the main body with the opening of the hook facing downward, so when the tool is hooked onto a hooked member such as a rebar or a wall, the longitudinal side of the main body is held approximately parallel to the rebar, wall, etc. This reduces the amount that the main body protrudes from the hooked member, and even when the tool is hooked, it does not get in the way of work, allowing for smooth movement and work at the work site. Furthermore, since the first hook mounting portion and the second mounting portion, which have the above-mentioned effects, are provided in a single tool, it is possible to improve work efficiency and reduce the burden on workers in a variety of situations at various work sites.

[0014] The first bundling machine of the present disclosure has a storage section for storing the wire and a gripping section on the underside of the main body, so the center of gravity of the bundling machine is located below the main body, more specifically, near the storage section. Therefore, when such a bundling machine is hooked onto a target object, such as a rebar, via a hook attached to the hook mounting section, the bundling machine can be held stably without significant tilt (movement) or instability due to the position of the center of gravity. In other words, because the bundling machine is stably hooked onto the target object, problems such as the bundling machine falling off the rebar are unlikely to occur. Furthermore, since the hook mounting section is attached so that the hook is on the upper side of the main body and the hook opening faces forward, when the hook is attached to the hook mounting section, after tying a rebar located in front of the worker, the worker can hook the rebar (target object) with minimal movement by tilting the front end of the main body, where the bundling section is located, downward, without having to turn his / her wrist. Therefore, in cases where the hooking operation is repeated when the binding machine is in use and when it is not in use, the work efficiency can be improved and the workload on the worker can be reduced.

[0015] The second bundling machine of the present disclosure has a wire-receiving storage section and a gripping section on the underside of the main body, so the center of gravity of the bundling machine is located below the main body, more specifically, near the storage section. Therefore, when such a bundling machine is hooked onto a hooked member, such as a rebar, via a hook attached to the hook mounting section, the bundling machine can be held stably without significant tilt (movement) or instability due to the position of the center of gravity. In other words, because the bundling machine is stably hooked onto the hooked member, problems such as the bundling machine falling off the rebar are unlikely to occur. Furthermore, the hook mounting section is attached so that the hook faces the side of the main body with the hook opening facing downward. Therefore, when the bundling machine is hooked onto a hooked member, such as a rebar or a wall, the longitudinal side of the main body is held approximately parallel to the rebar or wall. This reduces the amount of protrusion of the main body relative to the hooked member, so the bundling machine does not interfere with work even when it is hung, allowing for smooth movement and work at the work site.

[0016] According to the third binding machine of the present disclosure, the hook attachment portion is attached so that the hook is on the upper surface of the main body portion and the opening of the hook faces forward. Therefore, when the hook is attached to the hook attachment portion, after binding a rebar located in front of the worker, the worker can hook the rebar (the object to be hooked) with a small movement by tilting the front end of the main body portion where the binding portion is located downward, without having to turn his / her wrist. Therefore, when the worker repeatedly performs the hooking operation while using and not using the binding machine, work efficiency is improved and the worker's workload is reduced.

Note that the reinforcing bar binding machine 1A is an example of a tool or binding machine, and in this specification the reinforcing bar binding machine 1A may be referred to as a tool or binding machine.

[0020] The reinforcing bar binding machine 1A includes a main body 10 configured with a substantially rectangular parallelepiped housing. A binding unit (output unit) 4 is provided at one longitudinal end (front end) of the main body 10, and a drive unit 8 that drives the binding unit 4 is housed inside the main body 10. The reinforcing bar binding machine 1A also includes a magazine (storage unit) 2 that stores and delivers wire W at one end in the short direction (direction perpendicular to the longitudinal direction) of the main body 10, i.e., on the underside 10e of the main body 10, and a gripping unit 11 located on the underside 10e of the main body 10 and behind the magazine 2 (in the longitudinal direction). The binding unit 4 protrudes from the front end of the main body 10 and includes a curling unit 5 that curls the wire W fed from the magazine 2, and a twisting unit 7 that twists the wire W curled by the curling unit 5.

[0021] The reinforcing bar binding machine 1A is provided with a first hook mounting portion 210 located on the top surface 10a side of the main body 10 (the opposite side of the main body 10 from the bottom surface 10e side) to which a U-shaped hook 200A with one open end can be attached, and a second hook mounting portion 310 located on the left side surface 10b side of the main body 10 to which a hook 300 can be attached. Note that in this embodiment, the top surface 10a side includes not only the top surface 10a of the main body 10, but also the vicinity of the boundary between the top surface 10a of the main body 10 and the left side surface 10b, right side surface 10c, or rear end surface.

[0022] The reinforcing bar binding machine 1A includes a cover part 250 that is provided along the front-to-rear direction (longitudinal direction) so as to cover at least a portion of the upper surface 10a of the main body part 10. The cover part 250 has a guide surface 250a for guiding the reinforcing bar S to the opening 201 of the first hook 200A when the reinforcing bar (hooked member) S is hooked on the first hook 200A attached to the first hook attachment part 210a or the like.

[0023] As shown in Figures 1 to 5, the magazine 2 is located relatively forward of the main body 10 and extends downward from the underside 10e of the main body 10. A reel 20 around which a long wire W is wound so as to be able to be unwound is rotatably and detachably stored within the magazine 2. The wire W may be a wire made of a metal wire that can be plastically deformed, or may be a wire made of a metal wire coated with resin or a twisted wire.

[0024] The grip 11 is a portion that an operator holds during operation or transportation, and is provided on the underside 10e of the main body 10. The grip 11 is provided behind the magazine 2 so as to face the magazine 2, and extends downward from the underside 10e of the main body 10. A trigger 12 is provided at the front base end of the grip 11, which the operator uses to turn the bundling operation on and off. Note that the execution of the bundling operation may be combined with the activation of a contact switch 9 provided at the tip of the main body 10. The grip 11 has a battery attachment portion at its lower tip to which a battery 15 can be detachably attached.

[0025] As shown in FIGS. 1 and 2, the cover portion 250 is formed of an elongated flat plate member having a generally U-shaped cross section and extending in the front-to-rear direction, and covers substantially the entire top surface 10a of the main body portion 10. The top surface of the cover portion 250 forms a guide surface 250a for slidably guiding the reinforcing bar S from the front of the main body portion 10 toward the opening 201 of the first hook 200A. A sloped surface 250b is provided on the front end side of the cover portion 250, continuing from the guide surface 250a and gradually increasing in height from the front to the rear. The sloped surface 250b picks up the reinforcing bar S when the first hook 200A is hooked onto it and guides it into the opening 201 of the first hook 200A.

[0026] The cover part 250 has a left side part 250c and a right side part 250d that stand downward from both ends of the guide surface 250a in the left-right direction. The front sides of the left side part 250c and the right side part 250d of the cover part 250 and the rear sides of the left side part 250c and the right side part 250d of the cover part 250 are attached to the left side surface 10b and the right side surface 10c of the main body part 10, respectively, by fastening means 600 such as bolts and nuts.

[0027] As shown in FIGS. 1 and 2, the cover unit 250 has a plurality of first hook mounting portions 210a, 210b, 210c, 210d, and 210e arranged from the front to the rear of the guide surface 250a. Providing a plurality of first hook mounting portions 210a allows the mounting position of the first hook 200A to be selected and changed depending on the usage environment, the operator's preferences, and the like. While the first hook mounting portions 210a and the like are provided on the guide surface 250a of the cover unit 250 in this embodiment, the first hook mounting portions 210a and the like may be provided directly on the main body unit 10. Although five first hook mounting portions 210a and the like are provided, the number is not limited to five.

[0028] The first hook mounting portion 210a has an engagement hole 212a into which the engagement piece 202 of the first hook 200A is fitted, and screw holes 214a into which the screws 206 are screwed. The first hook mounting portion 210d has an engagement hole 212d into which the engagement piece 202 of the first hook 200A is fitted, and screw holes 214d into which the screws 206 are screwed. Note that the first hook mounting portions 210b, 210c, and 210e have the same configuration as the above-described first hook mounting portion 210a, etc., and therefore detailed description thereof will be omitted.

[0029] As shown in FIGS. 1 to 5, the first hook 200A is a component for hooking the reinforcing bar binding machine 1A onto a reinforcing bar S. In this embodiment, the first hook 200A is formed of a flat plate member bent into a U-shaped side surface. In this embodiment, the first hook 200A has a slit formed along its longitudinal direction, giving it a bifurcated shape, but this shape is not limited to this. Note that the first hook 200A does not necessarily have to be U-shaped; for example, it may be J-shaped, L-shaped, U-shaped, or crank-shaped. That is, the first hook 200A only needs to have a hooking portion for hooking onto a reinforcing bar and a fixing portion for fixing to the cover 250 or the main body 10. The following describes the case where the first hook 200A is attached to the first hook attachment portion 210d.

[0030] 2 and other figures, an engagement piece 202 and insertion holes 204, 204 are provided on the base end side of the first hook 200A (the end on the side of the first hook mounting portion 210d). The engagement piece 202 is formed to protrude from the base end of the first hook 200A toward the main body 10 and is configured to be able to engage with the engagement hole 212d of the first hook mounting portion 210d. The insertion holes 204, 204 are drilled at positions facing the screw holes 214d, 214d of the first hook mounting portion 210d.

[0031] In the present embodiment, the engagement piece 202 of the first hook 200A is fitted into the engagement hole 212d of the first hook mounting portion 210d, and the screws 206 are threadedly engaged with the screw holes 214d of the first hook mounting portion 210d through the insertion holes 204, 204, thereby fixing the first hook 200A to the main body portion 10 (cover portion 250). At this time, as shown in Fig. 3 etc., the first hook 200A is attached to the first hook mounting portion 210d so that the opening 201, into which the reinforcing bar S is inserted, faces forward in the front-to-rear direction.

[0032] 1 to 3, the second hook mounting portion 310 is provided on a protruding portion 250e that protrudes downward from the left side portion 250c of the cover portion 250. The second hook mounting portion 310 has an engagement hole 312 with which the engagement piece 302 of the second hook 300 is engaged, and screw holes 314, 314 into which the screws 306, 306 are screwed.

[0033] In this embodiment, the second hook mounting portion 310 is provided on the left side surface 10b of the main body portion 10, but it may be provided on the right side surface 10c of the main body portion 10, or on both the left side surface 10b and the right side surface 10c of the main body portion 10. Furthermore, the second hook mounting portion 310 may be provided directly on the main body portion 10, instead of on the cover portion 250.

[0034] The second hook 300 is a component for hooking the reinforcing bar binding machine 1A onto the reinforcing bar S from the left side surface 10b side, and like the first hook 200A, is composed of a flat plate member bent into a U-shaped side surface. In this embodiment, the second hook 300 has a slit formed along its longitudinal direction, giving it a bifurcated shape, but is not limited to this shape. Note that, like the first hook 200A, the second hook 300 does not necessarily have to be U-shaped, and may be, for example, J-shaped, L-shaped, U-shaped, or crank-shaped.

[0035] 2 and 5, etc., an engagement piece 302 and insertion holes 304, 304 are provided on the base end side of the second hook 300 (the end side on the second hook mounting portion 310 side). The engagement piece 302 is formed to protrude from the base end of the second hook 300 toward the main body portion 10, and is configured to be able to engage with the engagement hole 312 of the second hook mounting portion 310. The insertion holes 304, 304 are drilled at positions facing the screw holes 314, 314 of the second hook mounting portion 310.

[0036] In this embodiment, the engagement piece 302 of the second hook 300 is fitted into the engagement hole 312 of the second hook mounting portion 310, and the screws 306, 306 are threaded into the screw holes 314, 314 of the second hook mounting portion 310 via the insertion holes 304, 304, thereby fixing the second hook 300 to the left side surface 10b (cover portion 250) of the main body portion 10.

[0037] In this case, as shown in FIGS. 3 and 5, when the main body 10 is viewed from the front (front view), the second hook 300 is attached to the second hook attaching portion 310 so as not to block the opening 201 of the first hook 200A attached to the first hook attaching portion 210d, etc. Furthermore, the second hook attaching portion 310 attaches the second hook 300 so that the second hook 300 does not protrude from the guide surface 250a of the cover portion 250. Note that, if the cover portion 250 is not provided, the second hook attaching portion 310 attaches the second hook 300 so that the second hook 300 does not protrude from the top surface 10a of the main body 10. Furthermore, the second hook 300 may be attached to the second hook attaching portion 310 so that the opening 301 of the second hook 300 is on the lower or diagonally lower side in the vertical direction of the main body 10 and faces the center of gravity C of the rebar binding machine 1A.

[0038] Here, the center of gravity C of the rebar binding machine 1A is determined by the weights of the main body 10, curl forming unit 5, magazine 2, gripping unit 11, and battery 15, as well as their arrangement. The magazine 2, which stores the wire W and is therefore heavier than the other components (curl forming unit 5, gripping unit 11, etc.), is located in front of the underside 10e of the main body 10. Therefore, as shown in FIG. 3 , the center of gravity C of the rebar binding machine 1A is located in the space in front of the trigger 12 and near the magazine 2, in other words, in the space between the trigger 12 and the upper side of the magazine 2. In the rebar binding machine 1A, as the wire W stored in the magazine 2 is used, the amount of wire W decreases, and the overall weight of the rebar binding machine 1A also decreases. In this case, the center of gravity C of the rebar binding machine 1A also shifts slightly, but does not change significantly.

[0039] As shown in FIG. 4 and other figures, the wire feeding unit 3 includes a pair of feed gears 30 that clamp and feed one or multiple parallel wires W, and a feed motor (not shown) that drives the feed gear 30. The wire feeding unit 3 rotates the feed gear 30 when the rotation of the feed motor is transmitted via a transmission mechanism. The wire feeding unit 3 feeds the wire W clamped between the pair of feed gears 30 along the extension direction of the wire W. In a configuration in which multiple wires W, for example, two wires W, are fed, the two wires W are fed in a parallel state.

[0040] The curl forming unit 5 includes a curl guide 50 that curls the wire W fed by the wire feeding unit 3, and an guiding guide 51 that guides the wire W curled by the curl guide 50 to the twisting unit 7. The curl guide 50 and guiding guide 51 of the curl forming unit 5 are provided at the front end of the main body 10. In the rebar binding machine 1A, the path of the wire W fed by the wire feeding unit 3 is regulated by the curl forming unit 5, so that the wire W is wound around the rebar S.

[0041] As shown in Figure 4 etc., the cutting unit 6 includes a fixed blade unit 60, a movable blade unit 61 that cuts the wire W in cooperation with the fixed blade unit 60, and a transmission mechanism 62 that transmits the operation of the twisting unit 7 to the movable blade unit 61. The cutting unit 6 cuts the wire W by the rotational operation of the movable blade unit 61 with the fixed blade unit 60 as a fulcrum axis.

[0042] The twisting unit 7 includes a wire locking body 70 to which the wire W is locked, and a rotating shaft 72 that operates the wire locking body 70. The driving unit 8 includes a motor 80 and a reducer 81 that reduces speed and amplifies torque. The twisting unit 7 and driving unit 8 are configured such that the rotating shaft 72 and the motor 80 are connected via the reducer 81, and the rotating shaft 72 is driven by the motor 80 via the reducer 81. The wire locking body 70 includes a sleeve 71 that operates a first side hook and a second side hook (not shown) in conjunction with the rotation of the rotating shaft 72.

[0043] The wire W fed by the wire feeding unit 3 passes through the wire locking body 70 and is guided to the curl forming unit 5. The wire W is then curled by the curl forming unit 5, and the tip end of the wire W guided to the twisting unit 7 is locked in a manner that prevents it from slipping out of the wire locking body 70. When the wire W is subsequently cut by the cutting unit 6, the sleeve 71 moves forward, thereby bending the tip end of the wire W locked by the wire locking body 70 and the terminal end of the wire W cut by the cutting unit 6 toward the reinforcing bar S.

[0044] After the tip and end of the wire W are bent toward the reinforcing bar S, when the sleeve 71 moves further forward, the sleeve 71 rotates in conjunction with the rotating shaft 72, and the wire W locked by the wire locking body 70 is twisted.

[0045] [Example of using the first hook 200A] 6A shows an example of how the first hook 200A is used. For example, after completing a bundling operation (binding reinforcing bars S with wire W) and removing the curl forming unit 5 at the front end of the main body 10 from the reinforcing bars S, the worker tilts the curl forming unit 5 downward, aligning the top surface 10a of the main body 10 with the reinforcing bar arrangement surface, i.e., the reinforcing bar S, and then moves the reinforcing bar binding machine 1A downward while moving the guide surface 250a of the cover 250 along the reinforcing bar arrangement surface or while bringing the guide surface 250a into contact with the reinforcing bar S (while sliding the reinforcing bar S on the guide surface 250a), thereby hooking the reinforcing bar S onto the first hook 200A. Therefore, when hooking the first hook 200A onto the reinforcing bar S, the worker only needs to tilt the reinforcing bar binding machine 1A downward and move it, eliminating the need to perform an action such as turning the wrist to rotate the reinforcing bar binding machine 1A. This increases work efficiency and reduces the workload of the workers.

[0046] [Example of using the second hook 300] 6B shows an example of how the second hook 300 is used. For example, after completing a binding operation, the worker rotates the reinforcing bar binding machine 1A so that the left side surface 10b of the main body 10 is approximately parallel to the reinforcing bar arrangement surface, and hooks the second hook 300 onto the reinforcing bar S. By hooking the reinforcing bar S onto the second hook 300 in this way, the reinforcing bar binding machine 1A is held so that the main body 10 is approximately parallel to the reinforcing bar arrangement surface. This reduces the amount of protrusion of the main body 10 from the reinforcing bar S, and even if the reinforcing bar binding machine 1A is hooked onto the reinforcing bar S, it does not get in the way of work, allowing for smooth movement and work at the work site.

[0047] [Modification of the second hook mounting portion 310] The second hook mounting portion 310 is not limited to the mounting position shown in Figure 1, etc., as long as the second hook 300 can be mounted on the left side surface 10b and right side surface 10c of the main body 10 so that the opening 301 of the second hook 300 faces the center of gravity C of the rebar binding machine 1A.

[0048] 7 is a diagram showing a modified example of the second hook mounting portion 310. In addition to the second hook mounting portion 310 described above, the reinforcing bar binding machine 1A has second hook mounting portions 310A and 310B.

[0049] 7, the second hook mounting portion 310A is provided on the front side of the left side surface 10b of the main body 10, tilted so that the opening 301 of the second hook 300 faces the center of gravity C of the rebar binding machine 1A. In this case, the second hook mounting portion 310A mounts the second hook 300 so that the second hook 300 does not protrude from the top surface 10a of the main body 10 or the guide surface 250a of the cover 250, and does not block the opening 201 of the first hook 200A. The second hook 300 can also be mounted to the second hook mounting portion 310B using the same mounting method as the second hook mounting portion 310A.

[0050] According to the first embodiment, the first hook mounting portions 210a, etc. are mounted so that the first hook 200A faces the upper surface 10a of the main body 10 and the opening 201 of the first hook 200A faces forward. Therefore, when the first hook 200A is mounted on the first hook mounting portion 210a, etc., after tying a reinforcing bar S, etc. located in front of the worker, the worker can hook the reinforcing bar S, etc., with a small movement by tilting the front end of the main body 10, which includes the curl forming portion 5 and the twisting portion 7, downward without turning the wrist. Therefore, when the reinforcing bar tying machine 1A is repeatedly hooked while in use and when not in use, work efficiency is improved and the worker's workload is reduced.

[0051] Furthermore, because the magazine 2 that stores the wire W and the gripping portion 11 are located on the underside 10e of the main body 10 of the reinforcing bar binding machine 1A, the center of gravity C of the reinforcing bar binding machine 1A is located below the main body 10, more specifically near the magazine 2. Therefore, when such a reinforcing bar binding machine 1A is hooked onto a reinforcing bar S or the like via the first hook 200A attached to the first hook mounting portion 210a or the like, the reinforcing bar binding machine 1A can be held stably without tilting (moving) significantly and becoming unstable due to the position of the center of gravity. In other words, because the reinforcing bar binding machine 1A is stably hooked onto the reinforcing bar S or the like, problems such as the reinforcing bar binding machine 1A falling off the reinforcing bar are less likely to occur.

[0052] Furthermore, the second hook mounting portion 310 is attached so that the second hook 300 is on the left side surface 10b of the main body 10 and the opening 301 of the second hook 300 faces downward, so that when the reinforcing bar binding machine 1A is hooked onto a reinforcing bar S or the like, the left side surface 10b in the front-to-rear direction of the main body 10 is held substantially parallel to the reinforcing bar S or the like. This makes it possible to reduce the amount of protrusion of the main body 10 from the reinforcing bar S or the like, and even when the reinforcing bar binding machine 1A is hooked, it does not get in the way of work, allowing for smooth movement and work at the work site.

[0053] Furthermore, according to the first embodiment, the first hook mounting portion 210a etc. and the second mounting portion 310 having the above-described effects are provided in a single rebar binding machine 1A, which makes it possible to improve work efficiency and reduce the burden on workers in a variety of situations at a variety of work sites.

[0054] Furthermore, according to the first embodiment, the second hook 300 is attached to the second hook mounting portion 310 so as not to block the opening 201 of the first hook 200A, and the second hook 300 is attached to the second hook mounting portion 310 so as not to protrude from the upper surface 10a of the main body portion 10 or the guide surface 250a of the cover portion 250, thereby preventing the second hook 300 from becoming an obstacle when hooking the first hook 200A onto the reinforcing bar S.

[0055] Furthermore, according to the first embodiment, by providing the cover portion 250 and the guide surface 250a, the reinforcing bar S can be guided while sliding into the opening 201 of the first hook 200A, making it easier for the first hook 200A to hook onto the reinforcing bar S. Furthermore, by providing the cover portion 250, the reinforcing bar S can be prevented from coming into direct contact with the main body portion 10, thereby preventing damage to the main body portion 10.

[0056] <Second embodiment> The reinforcing bar binding machine 1B according to the second embodiment differs from the reinforcing bar binding machine 1A according to the first embodiment in that the hook 200B can be moved and retracted to the rear side of the main body 10. Note that components having substantially the same functions as those in the reinforcing bar binding machine 1A according to the above-described embodiment are given the same reference numerals and redundant explanations will be omitted.

[0057] [Configuration example of rebar binding machine 1B] 8A is a perspective view showing the hook 200B and the hook mounting portion 410 of the reinforcing bar binding machine 1B, and FIG. 8B is a side view of the hook 200B and the hook mounting portion 410. FIG.

[0058] 8A and 8B, the rebar binding machine 1B includes a lock plate 700 that locks the hook 200B in a use position P1, and a hook mounting portion 410 that supports the hook 200B so that the hook 200B can move from the use position P1 on the top surface 10a of the main body 10 to a retracted position P2 on the rear surface 10d. Here, the use position P1 is a position where the hook 200B is on the top surface 10a of the main body 10 and allows the hook 200B to hook onto a rebar S. The retracted position P2 is a position where the hook 200B is on the rear surface 10d of the main body 10 and does not get in the way or obstruct the operation or transportation of the machine.

[0059] As shown in FIG. 8A, the lock plate 700 is a flat member with a generally U-shaped cross section, and covers the rear side of the upper surface 10a of the cover portion 250. The rear end of the lock plate 700 is provided with retaining portions 702, 702 for locking the hook 200B in the use position P1. As shown in FIG. 8B, the retaining portions 702, 702 are provided to protrude upward (float) from the plane of the lock plate 700 by at least the thickness of the hook 200B so that the hook 200B can be inserted below them. Note that in this embodiment, the retaining portions 702, 702 are configured to be provided at two locations to match the bifurcated shape of the hook 200B, but this is not limited thereto and can be modified as appropriate depending on the shape of the hook 200B.

[0060] The lock plate 700 has a left side portion 700a and a right side portion 700b that stand downward from both ends in the left-right direction. A first shaft 720 and a second shaft 722 extending in the left-right direction are inserted through the left side portion 700a and the right side portion 700b of the lock plate 700, and through the left side portion 250c and the right side portion 250d of the cover portion 250 that are arranged inside the left side portion 700a and the right side portion 700b, respectively, as shown in Fig. 8A. The openings that support the first shaft 720 and the second shaft 722 of the cover portion 250 are elongated holes (not shown), and the lock plate 700 is configured to be movable in the front-rear direction relative to the cover portion 250.

[0061] 8A and 8B, the hook attachment portion 410 has a flat plate member 412 extending in the left-right direction of the main body portion 10, and locking portions 414, 414 erected downward from both ends of the flat plate member 412. Note that the locking portions 414 have the same configuration on both the left and right sides, and therefore, for convenience, only one of them will be described below.

[0062] Folded portion 208 of hook 200B is attached to the center of the top surface of flat plate member 412 by fastener 420. Folded portion 208 is a portion that extends by folding back from the base end of hook 200B toward the curved portion on the opposite side. Hook 200B is configured to be rotatable around the axis of fastener 420, allowing the orientation of hook 200B to be changed.

[0063] 8B, the locking portion 414 has a generally circular shape in a plan view, and is disposed inside the left side portion 250c of the cover portion 250. A third shaft 724 is inserted through the locking portion 414 and the left side portion 250c of the cover portion 250. The opening 414c that supports the third shaft 724 of the locking portion 414 is an elongated hole, and the third shaft 724 is configured to be movable in the front-rear direction relative to the locking portion 414.

[0064] 8A, a tension spring 726 is provided between the second shaft 722 and the third shaft 724. One end of the tension spring 726 is attached to the second shaft 722, and the other end is attached to the third shaft 724. As a result, the second shaft 722 and the third shaft 724 are biased in directions facing each other by the elastic force of the tension spring 726.

[0065] As shown in FIG. 8B, an inwardly protruding dowel 730 is provided on the inner surface of the left side portion 250c of the cover portion 250. A first recess 414a and a second recess 414b are formed at a predetermined distance from each other on the periphery of the lock portion 414. The first recess 414a engages with the dowel 730 when the hook 200B is in the use position P1, thereby locking the hook 200B in the use position P1. The second recess 414b engages with the dowel 730 when the hook 200B is in the retracted position P2, thereby locking the hook 200B in the retracted position P2.

[0066] [Example of operation of rebar binding machine 1B] Next, a description will be given of the operation when the hook 200B is moved from the use position P1 on the top surface 10a of the main body 10 to the retracted position P2 on the rear surface 10d of the main body 10. Figures 9A to 9C are operation diagrams of the rebar binding machine 1B when the hook 200B is moved from the use position P1 to the retracted position P2.

[0067] 9A, the operator slides lock plate 700 held in one hand forward relative to cover portion 250. As a result, pressing portions 702, 702 move forward and are displaced from the base end portion of hook 200B, thereby unlocking hook 200B.

[0068] Next, the worker grasps hook 200B with the other hand and rotates hook 200B rearward, as shown in Fig. 9B. As a result, locking portion 414 moves rearward relative to third shaft 724 through opening 414c, causing first recess 414a of locking portion 414 to disengage from dowel 730, and the engagement between first recess 414a and dowel 730 is released.

[0069] Next, when the hook 200B rotates from the usage position P1 to the retracted position P2 using the third shaft 724 as a fulcrum, the locking portion 414 is biased forward by the tension spring 726, so that the second recess 414b of the locking portion 414 engages with the dowel 730. This causes the hook 200B to be held at the retracted position P2.

[0070] Next, as shown in FIG. 9C , the worker rotates hook 200B 180° around the axis of stopper 420 as a fulcrum so that opening 201 of hook 200B faces downward, thereby turning hook 200B upside down. Hook 200B is biased forward by tension spring 726, and folded portion 208 of hook 200B contacts rear surface 10d of main body 10, preventing hook 200B from rotating due to the frictional force. This series of actions allows hook 200B to move from use position P1 to retracted position P2. Note that by performing the reverse of the above-described series of actions, hook 200B can be moved from retracted position P2 to use position P1.

[0071] As described above, according to the second embodiment, for example, when the hook 200B on the top surface 10a of the main body 10 becomes an obstacle during bundling work, the hook 200B can be retracted from the top surface 10a of the main body 10 to the rear surface 10d, etc., of the main body 10. This improves work efficiency. In the second embodiment, the first hook mounting portion 210 is moved to the rear surface 10d, but it may be configured to be movable to the left side surface 10b or the right side surface 10c. By moving the hook 200B from the top surface 10a of the main body 10 to, for example, the left side surface 10b, it can be used as a hook to hook onto rebar S or the like. Of course, the hook mounting portion provided on the left side surface 10b or the right side surface 10c of the main body 10 may also be configured to be movable to the top surface 10a of the main body 10. This allows one hook 200B to be used according to various work site conditions, thereby reducing costs compared to using two hooks.

[0072] <Third embodiment> The reinforcing bar binding machine 1C of the third embodiment differs from the reinforcing bar binding machine 1A of the first embodiment in that when the hook 200C is not in use, the hook 200C can be retracted to the side of the main body 10. Note that components having substantially the same functions as those in the reinforcing bar binding machine 1A of the above-described embodiment are assigned the same reference numerals and redundant explanations will be omitted.

[0073] [Configuration example of rebar binding machine 1C] Fig. 10 is a perspective view of a reinforcing bar binding machine 1C according to the third embodiment, seen from the rear left side. Fig. 11A is a cross-sectional view showing a fastener 520 that fastens a hook 200C, and Fig. 11B is a perspective view showing a state in which the hook 200C attached to the hook attachment portion 510a is locked in the retracted position P2.

[0074] The rebar binding machine 1C includes hook mounting portions 510a, 510b that support a hook 200C so that the hook 200C can move from a use position P1 (see FIG. 10) on the top surface 10a of the main body 10 to a retracted position P2 (see FIG. 12) on the left side surface 10b and right side surface 10c of the main body 10. The hook 200C according to the third embodiment has a pair of hook members 202a, 202b that are substantially U-shaped (J-shaped). Note that the hook 200C does not necessarily have to be U-shaped and may be, for example, J-shaped, L-shaped, C-shaped, or crank-shaped.

[0075] The hook mounting portion 510a rotatably mounts the hook member 202a from the top surface 10a side to the left surface 10b side of the main body 10. The hook mounting portion 510a is configured, for example, as a flat hinge, and is fastened to the guide surface 250a and the left surface 250c of the cover portion 250 with screws 512 with the base end of the hook member 202a inserted into the hook mounting portion 510a.

[0076] The hook mounting portion 510b rotatably mounts the hook member 202b from the top surface 10a side to the right side surface 10c side of the main body 10. The hook mounting portion 510b is configured, for example, as a flat hinge, and is fastened to the guide surface 250a and the right side portion 250d of the cover portion 250 with screws 514 with the base end of the hook member 202b inserted into the hook mounting portion 510b.

[0077] The hook mounting portions 510a and 510b mount the hook 200C including the hook members 202a and 202b such that the opening 201c for inserting the reinforcing bar S faces the front side of the main body 10 in the front-rear direction.

[0078] 10 and 11A, a stopper 520 having a hook portion on the tip side is rotatably attached to the tip end of hook member 202b constituting hook 200C. Stopper 520 joins (integrates) the tip ends of hook members 202a and 202b by fitting hook member 202a into the hook portion of the other hook member 202a in a state where the tip ends of hook members 202a and 202b are butted together above main body 10.

[0079] Hook 200C is biased toward the rear of main body 10 by springs 516 and 518. As shown in FIG. 11B and FIG. 12, which will be described later, pin 203a is inserted into and protrudes from hook member 202a of hook 200C. Hook mounting portion 510a has grooves 511a1 and 511a2 in two locations corresponding to use position P1 and retracted position P2. Similarly, although not shown in the figures, pin 203b is inserted into and protrudes from hook member 202b, and hook mounting portion 510b has grooves 511b1 and 511b2 in two locations. Pins 203a and 203b inserted into hook 200C biased by springs 516 and 518 enter grooves 511a1 and 511b1, respectively, at use position P1, and enter grooves 511a2 and 511b2, respectively, at retracted position P2, thereby restricting rotation of hook 200C.

[0080] [Example of operation of rebar binding machine 1C] FIG. 12 is a diagram illustrating the operation of the reinforcing bar binding machine 1C when the hook 200C is moved from the use position P1 to the retracted position P2.

[0081] As shown in FIG. 11A etc., when hook 200C is in use position P1, the hook portion of stopper 520 is rotated in a direction away from hook member 202a, whereby stopper 520 is disengaged from hook member 202a and hook members 202a and 202b are separated.

[0082] 12, the hook member 202a is pushed forward to disengage the pin 203a from one of the grooves 511a1, and rotated from the use position P1 on the top surface 10a of the main body 10 to the retracted position P2 on the left side surface 10b of the main body 10, thereby storing the hook member 202a on the left side surface 10b of the main body 10. Because the hook member 202a is biased by the spring 516, the pin 203a enters the other groove 511a2 (see FIG. 11B) and does not rotate from the stored position. Similarly, the hook member 202b is pushed forward to disengage the pin 203b from one of the grooves 511b1, and rotated from the use position P1 on the top surface 10a of the main body 10 to the retracted position P2 on the right side surface 10c of the main body 10, thereby storing the hook member 202b on the right side surface 10c of the main body 10. Since the hook member 202b is biased by the spring 518, the pin 203b enters the other groove 511b2 and does not rotate from the housed position.

[0083] As described above, according to the third embodiment, for example, when the hook 200C on the top surface 10a of the main body 10 gets in the way during bundling work, the hook 200C can be retracted from the top surface 10a of the main body 10 to the left side surface 10b, etc. This makes it possible to improve the efficiency of the work.

[0084] <Fourth embodiment> In the reinforcing bar binding machine 1D according to the fourth embodiment, the hook mounting portion 210a and the like are provided only on the top surface 10a side of the main body 10. Note that components having substantially the same functions as those in the reinforcing bar binding machine 1A according to the above-described embodiment are given the same reference numerals and redundant explanations will be omitted.

[0085] FIG. 13 is a perspective view of a reinforcing bar binding machine 1D according to the fourth embodiment, seen from the rear left side.

[0086] As shown in FIG. 13, the reinforcing bar binding machine 1D includes a main body 10, a binding unit 4 having a curl forming unit 5 and a twisting unit 7 provided at the longitudinal front end of the main body 10, and a drive unit 8 for driving the binding unit 4 housed inside (see FIG. 4). The reinforcing bar binding machine 1D includes a magazine 2 provided on the underside 10e of the main body 10 and storing the wire W in a feedable manner, a gripping unit 11 provided on the underside 10e of the main body 10 and behind the magazine 2, and a plurality of hook mounting portions 210a-210e located on the upper surface 10a of the main body 10 and capable of mounting a U-shaped hook 200A with one open end. In this embodiment, the hook 200A has a U-shaped side profile, but it does not necessarily have to be U-shaped. For example, it may be J-shaped, L-shaped, C-shaped, or crank-shaped.

[0087] The hook mounting portions 210d, etc. are provided along the front-to-rear direction (longitudinal direction) of the guide surface 250a of the cover portion 250. The hook mounting portions 210d, etc. are used to mount the hook 200A so that the opening 201 of the hook 200A faces the front side of the main body portion 10 in the front-to-rear direction. Note that the number of hook mounting portions 210d, etc. is not limited to five as described in the first embodiment, and any number can be provided. Furthermore, the hook mounting portions 210d, etc. may be provided directly on the upper surface 10a of the main body portion 10.

[0088] As shown in Fig. 8A etc., the hook mounting portion 210d etc. may be configured to mount the hook 200A movably from the top surface 10a side to the rear surface 10d side of the main body 10. Alternatively, as shown in Fig. 10 etc., the hook mounting portion 210d etc. may be configured to mount the hook 200A movably from the top surface 10a side to at least one of the left side surface 10b side and the right side surface 10c side of the main body 10.

[0089] As explained above, in the reinforcing bar binding machine 1D of the fourth embodiment, the magazine 2 that stores the wire W and the gripping unit 11 are located on the underside 10e of the main body 10, and therefore the center of gravity C of the reinforcing bar binding machine 1D is located below the main body 10, more specifically near the magazine 2. Therefore, when such a reinforcing bar binding machine 1D is hooked onto a reinforcing bar S or the like via the first hook 200 attached to the hook attachment unit 210, the reinforcing bar binding machine 1D can be held stably without tilting (moving) significantly and becoming unstable due to the position of the center of gravity. In other words, because the reinforcing bar binding machine 1D is stably hooked onto a reinforcing bar S or the like, problems such as the reinforcing bar binding machine 1D falling off the reinforcing bar are less likely to occur. Furthermore, the hook attachment part 210 is attached so that the hook 200 faces the top surface 10a of the main body 10 and the opening 201 of the hook 200 faces forward, and therefore when the hook 200 is attached to the hook attachment part 210, after tying the reinforcing bar S located in front of the worker, the worker can hook the reinforcing bar S with a small movement by tilting the front end side of the main body 10 where the curl guide part 5 is located downward, without turning the wrist. Therefore, when the reinforcing bar tying machine 1D is used and the hooking operation is repeated when it is not in use, work efficiency is improved and the workload on the worker is reduced.

[0090] <Fifth embodiment> In the reinforcing bar binding machine 1E according to the fifth embodiment, a hook attachment portion 310 is provided only on the left side surface 10b of the main body 10. Note that components having substantially the same functions as those in the reinforcing bar binding machine 1A according to the above-described embodiment are given the same reference numerals and redundant explanations will be omitted.

[0091] FIG. 14 is a perspective view of a reinforcing bar binding machine 1E according to the fifth embodiment, as viewed from the rear left side.

[0092] As shown in FIG. 14, the reinforcing bar binding machine 1E includes a main body 10, a binding unit 4 having a curl forming unit 5 and a twisting unit 7 provided at the longitudinal front end of the main body 10, and a drive unit 8 for driving the binding unit 4 housed inside (see FIG. 4). The reinforcing bar binding machine 1E includes a magazine 2 provided on the underside 10e of the main body 10 and storing the wire W in a feedable manner, a gripping unit 11 provided on the underside 10e of the main body 10 and behind the magazine 2, and a hook mounting unit 310 located on the left side 10b of the main body 10 and capable of mounting a U-shaped hook 300 with one open end. In this embodiment, the hook 300 has a U-shaped side profile, but it does not necessarily have to be U-shaped. For example, it may be J-shaped, L-shaped, U-shaped, or crank-shaped.

[0093] The hook mounting portion 310 is provided on the protruding portion 250e of the cover portion 250. The hook mounting portion 310 mounts the hook 300 so that the opening 301 of the hook 300 faces the center of gravity C (see FIG. 3) of the rebar binding machine 1E. The hook mounting portion 310 mounts the hook 300 so that the opening 301 of the hook 300 faces downward in the up-down direction of the main body portion 10. Note that, as shown in FIG. 7 and other figures, multiple hook mounting portions 310 may be provided, or they may be provided directly on the left side surface 10b of the main body portion 10. The hook mounting portion 310 may be provided on the right side surface 10c of the main body portion 10, or on both the left side surface 10b and the right side surface 10c.

[0094] As explained above, in the reinforcing bar binding machine 1E of the fifth embodiment, the magazine 2 that stores the wire W and the gripping unit 11 are located on the underside 10e of the main body 10, and therefore the center of gravity C of the reinforcing bar binding machine 1E is located below the main body 10, more specifically near the magazine 2. Therefore, when this reinforcing bar binding machine 1E is hooked onto a reinforcing bar S or the like via the second hook 300 attached to the hook attachment unit 310, the reinforcing bar binding machine 1E can be held stably without tilting (moving) significantly and becoming unstable due to the position of the center of gravity. In other words, because the reinforcing bar binding machine 1E is stably hooked onto the reinforcing bar S or the like, problems such as the reinforcing bar binding machine 1E falling off the reinforcing bar S or the like are less likely to occur. Furthermore, the hook mounting portion 310 is attached so that the hook 300 is on the left side surface 10b of the main body 10 and the opening 301 of the hook 300 faces downward, so that when the reinforcing bar binding machine 1E is hooked onto a reinforcing bar S or the like, the left side surface 10b in the front-to-rear direction of the main body 10 is held substantially parallel to the reinforcing bar S or the like. This makes it possible to reduce the amount of protrusion of the main body 10 from the reinforcing bar S or the like, and even when the reinforcing bar binding machine 1E is hooked, it does not get in the way of work, allowing for smooth movement and work at the work site.

[0095] Sixth Embodiment The reinforcing bar binding machine 1F according to the sixth embodiment differs from the reinforcing bar binding machine 1A according to the first embodiment in that a magazine 2 is provided on the side of the main body 10. Note that components having substantially the same functions as those of the reinforcing bar binding machine 1A according to the above-described embodiment are given the same reference numerals and redundant explanations will be omitted.

[0096] FIG. 15 is a perspective view of a reinforcing bar binding machine 1F according to the sixth embodiment, seen from the rear right side.

[0097] As shown in Figure 15, the reinforcing bar binding machine 1F comprises a main body 10, a binding unit 4 having a curl forming unit 5 and a twisting unit 7 provided at the longitudinal front end of the main body 10, and a drive unit 8 (see Figure 4) that drives the binding unit 4 is housed inside (see Figure 4). The reinforcing bar binding machine 1F comprises a magazine 2 provided at the longitudinal rear end of the main body 10 and that stores the wire W in a manner that allows it to be fed out, and a gripping unit 11 provided on the underside 10e of the main body 10.

[0098] The rebar binding machine 1F also includes a first hook mounting portion 210 located on the upper surface 10a of the main body 10, to which a U-shaped first hook 200A with one open end can be attached. In this embodiment, the first hook 200A has a U-shaped side surface, but it does not necessarily have to be U-shaped, and may be, for example, J-shaped, L-shaped, U-shaped, or crank-shaped.

[0099] The magazine 2 is provided at a position close to the right side surface 10c of the main body 10 to avoid the twisting unit 7 and the driving unit 8, which are located on the left side of the main body 10. The magazine 2 is formed of a space capable of accommodating a reel 20 around which the wire W is wound.

[0100] 15, a magazine cover part 22 that can open and close the space of the magazine 2 is provided on the rear side of the main body part 10. The magazine cover part 22 is attached to a support shaft 24 provided on the top surface 10a of the main body part 10, and is configured to be rotatable with the support shaft 24 as a fulcrum between a position where the magazine 2 is closed and a position where the magazine 2 is opened.

[0101] A first hook attachment portion 210 is provided on the upper surface of the magazine cover portion 22. The first hook 200A is attached to the first hook attachment portion 210 so that the opening 201 of the first hook 200A faces the front side in the front-rear direction of the main body portion 10. The first hook 200A is attached to the magazine cover portion 22 by fitting the engagement piece 202 (see FIG. 2) into the engagement hole 212 formed in the magazine cover portion 22 and threading the screw 206 into the screw hole 214 formed in the magazine cover portion 22 via the insertion hole 204 (see FIG. 2).

[0102] As described in the first embodiment, a plurality of first hook mounting portions 210 may be provided, or the first hook mounting portion 210 may be provided directly on the top surface 10a of the main body 10. As shown in Fig. 8A and other figures, the first hook 200A may be attached to the first hook mounting portion 210 so as to be movable from the top surface 10a of the main body 10 to the rear surface 10d. Furthermore, as shown in Fig. 10 and other figures, the first hook mounting portion 210 may be attached so as to be movable from the top surface 10a of the main body 10 to at least one of the left side surface 10b and the right side surface 10c.

[0103] Furthermore, as described in the first embodiment and the like, the second hook mounting portion 310 may be provided on at least one of the left side surface 10b and the right side surface 10c of the main body 10. In this case, the second hook 300 is mounted on the second hook mounting portion 310 so as not to block the opening 201 of the first hook 200A mounted on the first hook mounting portion 210 when the main body 10 is viewed from the front (front view). Furthermore, the second hook 300 is mounted on the second hook mounting portion 310 so as not to protrude from the top surface 10a of the main body 10 or the magazine cover portion 22.

[0104] Additionally, the second hook 300 is attached to the second hook attachment portion 310 so that the opening 301 of the second hook 300 is on the lower side in the front-to-rear direction of the rebar binding machine 1F and faces the center of gravity D of the rebar binding machine 1F. Here, the center of gravity D of the rebar binding machine 1F is determined by the weights and arrangement of the main body 10, curl forming portion 5, magazine 2, gripping portion 11, battery 15, etc. In this embodiment, the magazine 2, which is one of the heavy objects, is provided at the rear end of the main body 10 in the front-to-rear direction, and therefore the magazine 2 is located slightly behind the trigger 12, at the connection portion between the underside 10e of the main body 10 and the upper end of the gripping portion 11.

[0105] As explained above, the reinforcing bar binding machine 1F of the sixth embodiment has the magazine 2 at the rear end in the front-rear direction of the main body 10, so the center of gravity D of the reinforcing bar binding machine 1F is located near the magazine 2. Therefore, when such a reinforcing bar binding machine 1F is hooked onto a reinforcing bar S or the like via the hook 200A attached to the hook attachment part 210, the reinforcing bar binding machine 1F can be held stably without tilting (moving) significantly and becoming unstable in relation to the position of the center of gravity. In other words, because the reinforcing bar binding machine 1F is stably hooked onto the reinforcing bar S or the like, problems such as the reinforcing bar binding machine 1F falling off the reinforcing bar S or the like are less likely to occur.

[0106] Furthermore, according to the reinforcing bar binding machine 1F, the hook attachment section 210 is attached so that the hook 200 faces the top surface 10a of the main body section 10 and the opening 201 of the hook 200 faces forward, so when the hook 200 is attached to the hook attachment section 210, after binding a reinforcing bar S or the like located in front of the worker, the worker can hook the reinforcing bar S or the like with a small movement by tilting the front end side of the main body section 10, where the curl forming section 5 is located, downward, without having to turn his / her wrist over. Therefore, when the reinforcing bar binding machine 1F is used and not used, the work efficiency is improved and the workload on the worker is reduced.
