Description

  The present invention relates to a load fixing device for fixing a load to be loaded and transported on a vehicle or the like by using a linear object such as a wire, and in particular, the linear object by rotating an attachment member attached to the tip of the linear object. The present invention relates to a technique that makes it difficult for twisting to occur.

2. Description of the Related Art Conventionally, there is known a load fixing device including a winding mechanism for winding a cable body such as a wire connected to a load fixed to a floor of a vehicle or the like.
Some of these load fixing devices include four winding mechanisms as described above. Specifically, four winding mechanisms are arranged side by side in the front-rear direction as a pair of left and right pairs inside the load fixing device, and the tip of the linear body drawn from each winding mechanism is loaded. By attaching to the left and right sides of the object, the load can be fixed to the floor of a vehicle or the like.

  However, in the load fixing device including four sets of the winding mechanism as described above, when fixing the load to the floor, the four ropes are pulled out from the winding mechanism, and four hooks are attached one by one. There is an inconvenience that it has to be hooked on the frame of the load, and it takes time and labor to fix the work. In particular, when it is necessary to repeat the operation of hooking and unhooking the load, it tends to take time and workability tends to be lowered.

Therefore, as illustrated in FIG. 5A, a load fixing device including a connecting portion 335 that can connect two hooks and a mounting portion 330 that has a curved gripping portion 333 that can be attached to a load is known. (For example, refer to Patent Document 1). In such a load fixing device, the distal end portion (hook, see FIG. 5B) of the cable body 315 pulled out from two winding mechanisms arranged in the front-rear direction inside the device is used as the attachment portion 330. When connecting to the connecting portion 335 and fixing the load to the floor, the attachment portion 330 is taken out from the storage case to pull out the cable body 315 from the two winding mechanisms at the same time, and the grip portion 333 of the attachment portion 330 is It can be attached to the load. According to the load fixing device configured as described above, there is no need to pull out the plurality of cable bodies 315 from the respective winding mechanisms and hook the tip portions one by one on the load as in the conventional case, and the operation can be performed with a simple operation. The load can be quickly fixed to the floor, fixing work can be done in a short time, and workability is greatly improved.
JP 2004-159720 A (page 4, FIG. 3)

  However, in the load fixing device as described above, when the cable 315 is pulled out from the two winding mechanisms at the same time by removing the attachment portion 330 from the storage case, the grip portion 333 of the attachment portion 330 is removed from the load. For example, the attachment portion 330 may rotate in a state where the tip ends of the two striated bodies 315 are hooked on the connecting portion 335 described above. There was a possibility that the striated body 315 would be twisted by acting. In addition, when the strip body 315 is twisted in this way, loosening of the strands, floating, kinks, and the like are likely to occur in the strip body 315.

  Even when the attachment portion 330 as described above is not used, there is a risk that the rope body 315 may be twisted when the hook is hooked on the load. Similarly, loosening, floating, kink, etc. There was a problem that it was liable to be generated in the striated body 315. Further, even when a single wire is used instead of the striated body 315, there is a problem that when the single wire is twisted, the single wire is deformed or deteriorates.

  The present invention has been made in view of such problems, and the object of the present invention is a load fixing device for fixing a load to be loaded and transported on a vehicle or the like using a linear body such as a wire. An object of the present invention is to provide a technique that makes it difficult for twisting to occur in a linear body.

  The load fixing device according to claim 1, which has been made to solve the above problems, includes a hook that is detachably attached to a part of the load, a linear body having a tip attached to the hook, A winding pulley coupled to a rear end of the linear body, capable of winding the linear body, and applied with a biasing force by a biasing means in a winding direction for winding the linear body; A load fixing device provided with at least one set, wherein the hooks attached to the tip end portions of the linear bodies drawn from the at least one set of take-up pulleys are detachably mounted, and the load An attachment member having a curved gripping portion that is detachably attached to a part of an object, and prevents the linear body from being twisted due to an input of external power for twisting the linear body A twist preventing portion.

  According to the load fixing device of the present invention configured as described above, the following operational effects can be obtained. That is, a hook attached to the tip of the linear body drawn from one or more winding pulleys is detachably attached to the connecting part of the attachment member, and the gripping part of the attachment member is part of the load. By detachably attaching to the linear body, the linear body is detachably attached to a part of the load via the attachment member. Then, for example, when the mounting member rotates, the rotational moment acts on the linear body to twist about its longitudinal direction due to the input of external power for twisting the linear body. However, the twist preventing portion prevents the linear body from being twisted. Thereby, it is possible to make it difficult for twisting to occur in a linear body such as a wire drawn out from the take-up pulley.

In addition, about the above-mentioned twist prevention part, (A) The case where it forms in an attachment member, (B) The case where it forms in a linear body, etc. can be considered. This will be described in order below.
(A) In the case where the twist preventing portion is formed on the attachment member, specifically, as described in claim 2, the above-described attachment member has a configuration in which the connecting portion can rotate with respect to the grip portion. It can be considered to have a twist preventing part.

  If comprised in this way, by adding the attachment member of the above invention to the load fixing device provided with a linear body, a take-up pulley, etc., it is less cost compared with the existing load fixing device. Thus, it is possible to make it difficult for twisting to occur in a linear body such as a wire drawn from the take-up pulley.

  In addition, about the structure (twisting prevention part) which enables the above connection parts to rotate with respect to a holding part, it is possible to be comprised with the material which is more easily twisted than a linear body, for example (Claims). 3). If comprised in this way, when a rotational moment acts so that it may twist around the longitudinal direction with respect to a linear body, since the above-mentioned twist prevention part twists, it can be made into a linear body with fewer parts. Twist can be made difficult to occur.

  Moreover, about the structure (twisting prevention part) which enables the connection part as mentioned above to rotate with respect to a holding part, the part fixed to a connection part is comprised so that rotation with respect to another part is possible. (Claim 4). If comprised in this way, when a rotational moment will act with respect to the linear body around the longitudinal direction, the part fixed to the connection part in a twist prevention part will rotate with respect to another part. That releases the rotational moment. That is, since the rotational moment is not accumulated in the twist preventing portion, it is possible to prevent the linear body, the attachment member, and the twist preventing portion from being deformed.

  (B) Further, in the case where the twist preventing portion is formed in the linear body, specifically, as described in claim 5, the hook described above is linear in the longitudinal direction of the linear body. It is conceivable to have a structure that can rotate with respect to the body as a twist preventing portion. If comprised in this way, even if it is a load fixing apparatus which does not have the above attachment members, as mentioned above, the rotational moment acted on the linear body so that it might twist around the longitudinal direction. Sometimes, it is possible to prevent twisting of a linear body such as a wire.

  In addition, about the structure (twisting prevention part) which can rotate the front-end | tip part of the above linear bodies with respect to a linear body around the longitudinal direction, it is a material which twists more easily than a linear body, for example. It is conceivable to be configured (claim 6). If comprised in this way, when a rotational moment acts so that a hook may be twisted around the longitudinal direction with respect to a linear body, since the above-mentioned twist prevention part will twist, it is linear with fewer parts. It is possible to make it difficult for the body to twist.

  In addition, with respect to the configuration (twist prevention portion) that allows the tip of the linear body to rotate about the longitudinal direction with respect to the linear body as described above, the portion fixed to the connecting portion of the hook is the other part. It is conceivable that the portion is configured to be rotatable with respect to the portion (Claim 7). If comprised in this way, when a rotation moment will act so that a hook may be twisted around the longitudinal direction with respect to a linear body, the part fixed to the connection part in a hook will rotate with respect to another part. That releases the rotational moment. That is, since the rotational moment is not accumulated in the twist preventing portion, it is possible to prevent the linear body, the attachment member, and the twist preventing portion from being deformed.

  By the way, as a specific example of the above-mentioned linear body, a striated body such as a single wire or a stranded wire can be cited. Of these, for the cable body as a linear body, when a rotational moment acts so as to be twisted around its longitudinal direction, loose wires, floats, kinks, etc. are likely to occur in the wire. There was a particular problem. On the other hand, it is conceivable to form a linear body having a configuration in which a plurality of wires are wound around a core material. With this configuration, when a rotational moment is applied to the wire body as a linear body so as to be twisted in the longitudinal direction, the wire loosening that is likely to occur particularly when the wire body is twisted. In addition, floating, kinks, etc. can be made difficult to occur.

As shown in FIG. 1B, the attachment member 30 includes a member main body 31, a grip portion 33 that is detachably attached to a part of the load, and a hook attached to a wire drawn from the take-up pulley. Are provided with two ring portions 35 as connecting portions to be detachably mounted.

  Among these, the member main body 31 is made of a block-shaped metal material, and attachment holes 31a for rotatably attaching the ring portion 35 are formed on both sides thereof. The inside of the mounting hole 31a is formed in a shape corresponding to a rotating shaft 35b (described later) of the ring portion 35 (see FIG. 1C). An attachment hole 31b for attaching the grip portion 33 is formed in the upper part of the member main body 31 so as to penetrate the upper part of the member main body 31 in the left-right direction.

  The gripping portion 33 is made of a shaft-like metal member, and is formed so that both ends of the horizontal central portion 33a are bent vertically upward, and the tip portions 33d and 33e of the bent portions 33b and 33c are formed in a bowl shape.

In addition, the front-end | tip part 35c of this rotating shaft 35b is formed in the disk shape. And the ring part 35 is rotatably attached with respect to the member main body 31 because the rotating shaft 35b is inserted in the attachment hole 31a of the member main body 31. As shown in FIG.

The mounting hole 31a of the member main body 31 and the rotating shaft 35b of the ring portion 35 correspond to the “twist prevention portion” in the claims.
In addition, since the other structure of the load fixing apparatus 10 of this embodiment is based on a well-known technique, detailed description is abbreviate | omitted here.

[Effect of the first embodiment]
(1) Thus, according to the load fixing device 10 of 1st embodiment, there exist the following effects. That is, the load fixing device 10 is detachably mounted with hooks 13 and 14 that are tip portions of the wires 15 and 16 drawn from a pair of winding mechanisms disposed in the front-rear direction in the storage case 20. An attachment member 30 having a ring portion 35 and a grip portion 33 that is detachably attached to a part of the load is provided. Among these, the ring portion 35 is formed with a shaft-like rotation shaft 35b for attachment to the attachment hole 31a of the member body 31, and the tip portion 35c of the rotation shaft 35b is formed in a disc shape. On the other hand, attachment holes 31 a for rotatably attaching the ring portion 35 are formed on both sides of the member main body 31. The inside of the attachment hole 31a is formed in a shape corresponding to the rotation shaft 35b of the ring portion 35. The rotation shaft 35 b of the ring part 35 is attached to the attachment hole 31 a of the member main body 31, and the ring part 35 is rotatable with respect to the member main body 31. Further, the hooks 13 and 14 which are the distal ends of the wires 15 and 16 are detachably attached to the two ring portions 35 and 35 of the attachment member 30, respectively, and the grip portion 33 of the attachment member 30 is a part of the load. By detachably mounting, the hooks 13 and 14 are detachably mounted on a part of the load via the mounting member 30. Then, for example, when the mounting member 30 is rotated, a rotational moment acts on the wires 15 and 16 so as to be twisted in the longitudinal direction due to the input of external power for twisting the wires 15 and 16. Even at times, the rotation of the ring portion 35 prevents the wires 15 and 16 from being twisted. Thereby, it is possible to make it difficult for the wire drawn from the take-up pulley to be twisted.

  (2) Further, according to the load fixing device 10 of the first embodiment, when a rotational moment acts on the wire so as to be twisted about its longitudinal direction, it is particularly likely to occur when the wire is twisted. It is possible to make it difficult for loosening, floating, kinking and the like to occur.

(3) Moreover, about the conventional load fixing apparatus, by adding the above-mentioned attachment member 30, it can make it difficult to generate | occur | produce twisting in a wire with less expense.
(4) According to the load fixing device 10 of the first embodiment, the rotation shaft 35 b of the ring portion 35 is attached to the attachment hole 31 a of the member main body 31, and the ring portion 35 is attached to the member main body 31. It can rotate with respect to it. As a result, when a rotational moment acts on the wires 15 and 16 so as to twist around the longitudinal direction, the ring portion 35 rotates with respect to the member main body 31 to release the rotational moment. That is, since the rotational moment is not accumulated inside the attachment member 30, it is possible to prevent the wires 15 and 16 and the attachment member 30, particularly the ring portion 35 and the member main body 31 from being deformed.

  (5) Moreover, according to the load fixing apparatus 10 of 1st embodiment, the two ring parts 35 and 35 are attached with respect to the member main body 31 so that it can rotate independently of the other. Thus, even if one of the two wires connected to the attachment member 30 is already twisted, the twist of the wire can be eliminated by rotating the ring portion 35.

[Other Embodiments]
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, It is possible to implement in the following various aspects.

  (1) In the above-described embodiment, the hooks 13 and 14 that are the tips of the wires 15 and 16 drawn from the pair of winding mechanisms disposed in the front-rear direction in the storage case 20 can be attached to and detached from the attachment member 30. Although the case of mounting is described as an example, the present invention can also be applied to a case where a hook, which is a tip portion of a wire drawn from one winding mechanism, is directly attached to the attachment member 30 without using the grip portion 33. Even in this case, for example, when the mounting member 30 is rotated, when the rotational moment acts on the wire to be twisted in the longitudinal direction due to the input of external power for twisting the wire. Even if it exists, it is prevented that a wire twists because the ring part 35 rotates. Thereby, it is possible to make it difficult for the wire drawn from the take-up pulley to be twisted.

  (2) In the above embodiment, in the attachment member 30, the rotation shaft 35 b of the ring portion 35 is attached to the attachment hole 31 a of the member main body 31, and the ring portion 35 is configured to be rotatable with respect to the member main body 31. However, the present invention is not limited to this, and the configuration (twisting prevention portion) that enables the connecting portion as described above to rotate with respect to the gripping portion is provided between the member main body 31 of the mounting member 30 and the ring portion 35. For example, the ring portion 35 may be configured to be rotatable with respect to the member main body 31 such that the connecting portion is made of a material that is more easily twisted than the wires 15 and 16. Specific examples of materials that are more easily twisted than the wires 15 and 16 as described above include resin materials and rubber materials. With this configuration, when a rotational moment acts on the wires 15 and 16 so as to be twisted in the longitudinal direction, the connecting portion between the member main body 31 and the ring portion 35 of the mounting member 30 described above is twisted. Therefore, the wires 15 and 16 can be made less likely to be twisted with a smaller number of parts.

  (3) In the above embodiment, in the attachment member 30, each of the two ring portions 35, 35 is attached to the member main body 31 so as to be rotatable independently of the other, but this is not restrictive. As illustrated in (a), a ring part 135 having two attachment holes for attaching two hooks may be integrally attached to the member main body 131 so as to be rotatable. Below, the structure of this attachment member 130 is demonstrated.

[Description of Configuration of Mounting Member 130]
As shown in FIG. 3A, the attachment member 130 includes a member main body 131, a grip portion 33 that is detachably attached to a part of the load, and two ring portions by bundling wires 134 in an annular shape. The connecting part 135 in which 135a was formed and the cylindrical shaft 137 by which the connecting part 135 is extrapolated are provided. In addition, since it was mentioned above about the holding part 33, detailed description is abbreviate | omitted here.

  The member main body 131 is made of a block-shaped metal material, and an attachment hole 131a for rotatably inserting the shaft 137 is formed in the lower part thereof. An attachment hole 131b for attaching the grip portion 33 is formed in the upper part of the member main body 131 so as to penetrate the upper part of the member main body 131 in the left-right direction.

  As for the wire 134, a cable body having a configuration in which a plurality of metal wires are wound around a metal core is used. Note that a single wire may be used for the wire 134. Further, the wire 134 may be a cable body other than metal. An example is a cloth rope or a resin rope.

  The shaft 137 is made of a cylindrical metal material, and both ends of the shaft 137 are caulked with the connecting portion 135 inserted into the shaft 137. Thus, the connecting portion 135 is rotatably attached to the member main body 131 by inserting the shaft 137 into the attachment hole 131 a of the member main body 131.

The mounting hole 131a, the connecting portion 135, and the shaft 137 of the member main body 131 described above correspond to the “twist prevention portion” in the claims.
If comprised in this way, there exist the following effects. That is, the hooks 13 and 14 which are the tip portions of the wires 15 and 16 are detachably attached to the two ring portions 135 and 135 of the connecting portion 135 of the attachment member 130, respectively, and the grip portion 33 of the attachment member 130 is attached to the load. The hooks 13 and 14 are detachably attached to a part of the load via the attachment member 130. Then, for example, when the attachment member 130 is rotated, a rotational moment acts on the wires 15 and 16 so as to be twisted around the longitudinal direction due to the input of external power for twisting the wires 15 and 16. Even at times, the connecting portion 135 of the mounting member 130 and the shaft 137 rotate to prevent the wires 15 and 16 from being twisted. Thereby, it is possible to make it difficult for the wire drawn from the take-up pulley to be twisted.

(4) Further, in the mounting member 130 described above, the shaft 137 is made of a cylindrical metal material, and both ends of the shaft 137 are caulked with the connecting portion 135 inserted into the shaft 137. However, the present invention is not limited to this, and as illustrated in FIG. 3B, two rings 139 are used instead of the shaft 137, and the two rings 135a are formed by bundling the wires 134 in an annular shape. The ring 139 may be extrapolated in the vicinity of the ring portion 135a of the connecting portion 135 in a state where the ring 139 is caulked. In this case, the above-described connecting portion 135 is rotatably attached to the member main body 131 by being inserted into the attachment hole 131a of the member main body 131 in a state where the ring 139 is fixed. Even if comprised in this way, there exists an effect similar to the said embodiment.

  The shaft 113b is made of a cylindrical metal material. One end of the shaft 113b is caulked with the hook body 113a inserted. Further, the inner diameter of the shaft 113b is larger than that of the opening at the end. A rotating shaft 113c to which one end of the wire 15 is fixed is inserted into the shaft 113b.

  The rotating shaft 113c is made of a cylindrical metal material. The outer diameter of the rotating shaft 113c is slightly larger than the inner diameter of the shaft 113b. The rotating shaft 113c is caulked with one end of the wire 15 inserted. The rotating shaft 113c is rotatably attached to the shaft 113b by being inserted into the shaft 113b with one end of the wire 15 fixed. The terminal 113d of the shaft 113b has an inner diameter smaller than the general diameter of the shaft 113b. For this reason, although the rotating shaft 113c can rotate, it does not come out with respect to the load in the pulling direction of the wire 15.

The shaft 113b and the rotating shaft 113c of the hook 113 described above correspond to the “twist prevention part” in the claims.
Note that the hook 114 has the same configuration as the hook 113 described above, and a detailed description thereof will be omitted here.

[Effects of Second Embodiment]
(1) Thus, according to the load fixing device 110 of the second embodiment, the rotating shaft 113c of the hook 113 is inserted into the shaft 113b with one end of the wire 15 being fixed, so that the shaft It is rotatably attached to 113b. As a result, for example, when the hook 113 rotates, a rotational moment acts on the wire 15 so as to be twisted about its longitudinal direction due to the input of external power for twisting the wire 15. Even so, the rotating shaft 113c of the hook 113 rotates with respect to the shaft 113b, thereby preventing the wire 15 from being twisted. This also applies to the hook 114. Therefore, it is possible to make it difficult for the wire drawn from the take-up pulley to be twisted.

  (2) Further, according to the load fixing device 110 of the second embodiment, when the rotational moment acts on the wire so as to be twisted in the longitudinal direction, it is likely to occur particularly when the wire is twisted. It is possible to make it difficult for loosening, floating, kinking and the like to occur.

  (3) Further, according to the load fixing device 110 of the second embodiment, the rotating shaft 113c of the hook 113 is inserted into the shaft 113b with one end of the wire 15 fixed as described above. Therefore, when the rotating moment is applied to the wire 15 so as to be twisted around the longitudinal direction, the rotating shaft 113c of the hook 113 is moved relative to the shaft 113b. The rotational moment is released by rotating. This also applies to the hook 114. That is, since the rotational moment is not accumulated in the hooks 113 and 114, the hooks 113 and 114 and the wires 15 and 16 can be prevented from being deformed.

[Other Embodiments]
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, It is possible to implement in the following various aspects.

  (1) In the above-described embodiment, the wires 15 and 16 are configured by a striated body having a configuration in which a plurality of metal wires are wound around a metal core, but is not limited thereto. The wires 15 and 16 may be configured using a single wire. Further, the wires 15 and 16 may be strips other than metal. An example is a cloth rope or a resin rope.

  (1) In the above embodiment, the hook 113 has the hook body 113a, the shaft 113b, and the rotation shaft 113c, and one end of the shaft 113b is caulked with the hook body 113a inserted. However, the present invention is not limited to this, and the hook body and the shaft may be integrally formed as illustrated in FIG. Specifically, the hook 213 has a hook main body 213a and a rotating shaft 113c. The hook main body 213a is made of a cylindrical metal material, and its tip is formed in a bowl shape. As for the inside, the inner diameter dimension is formed larger than the opening of the rear end 213b. In such a case, after the rotating shaft 113c with one end of the wire 15 fixed thereto is inserted into the hook body 213a, the diameter of the rotating shaft 113c is reduced by caulking the rear end portion 213b of the hook 113. Becomes rotatable with respect to the shaft 113b. If comprised in this way, the number of parts which comprise the hook 213 can be decreased, and the manufacturing cost can be reduced.

  (2) The load fixing device 110 may include the mounting member 30 described above. In this case, hooks 113 and 114, which are tip portions of the wires 15 and 16, are detachably attached to the two ring portions 35 and 35 of the attachment member 30, respectively, and the grip portion 33 of the attachment member 30 is part of the load. The hooks 113 and 114 are detachably attached to a part of the load via the attachment member 30. Then, for example, when the mounting member 30 is rotated, a rotational moment acts on the wires 15 and 16 so as to be twisted in the longitudinal direction due to the input of external power for twisting the wires 15 and 16. Even when the rotation axis 113c of the hook 113 rotates relative to the shaft 113b, the wire 15 is prevented from being twisted. This also applies to the hook 114. Further, the rotation of the ring portion 35 of the attachment member 30 prevents the wires 15 and 16 from being twisted. Thereby, it is possible to make it difficult for the wire drawn from the take-up pulley to be twisted.

  Further, the load fixing device 110 may include a mounting portion 330 as illustrated in FIG. In this case, the hooks 113 and 114 that are the tips of the wires 15 and 16 are detachably attached to the connecting portion 335 of the attachment portion 330, and the grip portion 333 of the attachment portion 330 is attachable to and detachable from a part of the load. By attaching, the hooks 113 and 114 are detachably attached to a part of the load via the attachment portion 330. Then, for example, when the attachment portion 330 is rotated, a rotational moment is applied to the wires 15 and 16 so that the wires 15 and 16 are twisted around the longitudinal direction due to input of external power for twisting the wires 15 and 16. Even when the rotation axis 113c of the hook 113 rotates relative to the shaft 113b, the wire 15 is prevented from being twisted. This also applies to the hook 114. Therefore, it is possible to make it difficult for the wire drawn from the take-up pulley to be twisted.

  (3) In the above embodiment, the rotation shaft 113c of the hook 113 is rotatably attached to the shaft 113b by being inserted into the shaft 113b with one end of the wire 15 fixed. The configuration is not limited to this, and the hooks 113 and 114 as described above can be rotated with respect to the wires 15 and 16 (twist prevention portion). The hooks 113 and 114 may be configured to be rotatable with respect to the wires 15 and 16. Specific examples of materials that are more easily twisted than the wires 15 and 16 as described above include resin materials and rubber materials. With this configuration, when the rotational moment acts on the wires 15 and 16 so as to twist around the longitudinal direction, the rear end portions of the hooks 113 and 114 are twisted. Thus, twisting of the wires 15 and 16 can be prevented.
