Description

[Technical Field]

[0001] To provide a rope hooking device which is provided on a cart, a loading platform, etc. and is used to secure a transported object with a rope, etc., and which, in particular, allows the position where the rope is hooked to be selected and prevents the position where the rope is hooked from shifting even when subjected to vibrations, impacts, etc. [Background technology]

[0002] BACKGROUND ART In order to secure transported goods to the loading platform of a truck vehicle, cart, bicycle, or the like with a binding member such as a rope, a hook is provided on the periphery of the loading platform, and the end or middle part of the rope is hooked onto this hook to secure the transported goods.

[0003] Such hooks are usually rod-shaped or L-shaped, and are installed at an appropriate position on the loading platform. They are used to hook the end or middle part of the rope when wrapping the rope around the object being transported (Patent Document 1).

[0004] Also, there is a hook device in which a metal rod is bent into a roughly U-shape or a roughly C-shape, and both ends of the rod are attached to the periphery of the loading platform (Patent Document 2). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Utility Model Application Publication No. 62-77077 [Patent Document 2] Publication No. 2017-88142 Summary of the Invention [Problem to be solved by the invention]

[0006] However, since the hooking device described in Patent Document 1 is fixedly attached at a predetermined position on the loading platform, there are cases where it is desired to hook the rope at a slightly different position depending on the shape of the transported object. If it is not possible to hook the rope at the desired position, the transported object may not be sufficiently secured.

[0007] Furthermore, the hook described in Patent Document 2, particularly the U-shaped hook, has a certain width and allows the position where the rope is hooked to be moved somewhat, but the range of movement is small, and it is not always possible to hook the rope in a position that matches the shape of the transported object. One possible solution to this problem is to increase the width of the U-shaped hook.

[0008] However, if the width of the U-shaped hook is increased, the rope hooked to the hook (specifically, its end or middle part) can move in the width direction of the hook, which creates the problem that if the transported item shifts due to vibration or impact during transport, the position where the rope was hooked will shift, causing the cargo to collapse.

[0009] In other words, since the hooking device is attached to the side edge of the cart, its width direction coincides with the direction in which the transported item is being transported (the front-to-back direction of the cart), and vibrations and impacts during transport can catch the rope and cause it to shift position.

[0010] Therefore, the object of this invention is to provide a rope hooking device that allows the hooking position of the rope to be selected appropriately in the direction in which the side edge of the loading platform extends, and that prevents the fastening of the transported object from loosening even when subjected to vibrations or impacts during transportation, thereby maintaining stable fastening of the transported object. [Means for solving the problem]

[0011] In order to solve the above problem, the invention described in claim 1 is characterized in that it is a rope hooking device that is installed at a predetermined position on the opposing side edges of a loading platform on which the transported goods are placed, and is equipped with a C-shaped or U-shaped hooking member having a hooking portion on which the end or middle portion of the rope that secures the transported goods is hooked, and an attachment portion that is attached to the side edge of the loading platform, and a separate member that is bridged between the middle portion of the hooking portion and the side edge of the loading platform to divide the space between the hooking member and the loading platform and form at least two insertion holes.

[0012] The invention described in claim 2 is characterized in that, in the rope hooking device described in claim 1, the hooking member has an attachment plate to which the mounting portion and the separate member are attached, and the hooking member is attached to the cargo bed via the attachment plate.

[0013] The invention described in claim 3 is a rope hook that is attached to predetermined positions on opposing side edges of a loading platform on which transported goods are placed, and is characterized by comprising: a joint for attaching to the side edge of the loading platform; a hook for hooking the end or middle part of a rope for securing the transported goods; a C-shaped or U-shaped rope engagement part having an attachment part that connects to the joint; and a separate part that is bridged between the middle part of the hook and the joint, dividing the space between the rope engagement part and the joint, and forming at least two insertion holes. [Effects of the Invention]

[0014] According to the invention described in claim 1, by attaching a C-shaped or U-shaped hooking member to the side edge of the loading platform, the hooking portion extends in a direction along the side edge of the loading platform, and the separate member divides the space between the hooking member and the loading platform, forming at least two insertion holes, so that the hooking position of the rope can be appropriately selected in the direction in which the side edge of the loading platform extends, allowing for flexible fastening of transported goods.

[0015] In addition, since the space between the hooking member and the loading platform is divided by the separate member, the position where the rope is hooked will not move even with vibrations or impacts during transportation, so the fastening of the transported goods will not loosen and the load can be prevented from falling over.

[0016] According to the invention described in claim 2, by making the mounting plate attached to the cargo bed part of the hooking member, the hooking member including the mounting plate can be made into a single component, and can be retrofitted to existing cargo beds.

[0017] According to the invention of claim 3, by providing a U-shaped or C-shaped rope engagement part on the side edge of the loading platform, the hooking part extends in a direction along the side edge of the loading platform, and the separate part divides the space between the rope engagement part and the loading platform to form at least two insertion holes, so that the hooking position of the rope can be appropriately selected in the direction in which the side edge of the loading platform extends, allowing for flexible fastening of transported goods. Furthermore, because the separate part divides the space between the rope engagement part and the loading platform, the hooking position of the rope does not move even with vibrations or impacts during transport, so that the fastening of transported goods does not loosen and cargo collapse can be prevented.

[0019] The present invention will be described below based on the illustrated embodiments.

[0020] Figures 1 to 3 show a trolley equipped with the rope hook of the present invention, and the trolley 1 comprises a trolley body 2, six casters 3 provided on the underside of the trolley body 2, and supports 4 provided at the four corners of the trolley body 2.

[0021] The bogie body 2 is made up of L-shaped corner members 5 provided at the four corners, outer frame members 6 that connect these corner members 5 front to back or left to right, and inner frame members 7 that connect opposing outer frame members 6. These outer frame members 6 and inner frame members 7 are made of, for example, rectangular hollow pipes made of aluminum alloy. The corner members 5 are made of, for example, aluminum alloy and formed by extrusion molding.

[0022] Three lower plates 8 are attached to the underside of the trolley body 2, near both longitudinal edges and in the center, so as to bridge between two outer frame materials 6 extending in the longitudinal direction, and the casters 3 are provided on the lower plates 8.

[0023] In addition, on the top surface of the trolley body 2, at positions other than the positions where the two lower plates 8 at the front and rear are provided, and at the center of the width of the central lower plate 8, an upper plate 9 consisting of an H-shaped checker plate in a plan view is attached so as to span between two outer frame materials 6 extending in the longitudinal direction, and the transported goods are loaded on the upper plate 9.

[0024] An insertion hole that penetrates vertically is formed in the corner of the corner member 5, and the support post 4 is inserted into the insertion hole. The support post 4 may be provided so that it can be inserted and removed freely from the insertion hole of the corner member 5, or it may be a bendable support post with its lower part fixed to the insertion hole of the corner member 5 at an appropriate position.

[0025] A rope hook 10 according to the present invention is attached to a predetermined position on the side edge of the bogie body 2 of such a bogie 1. Specifically, the bogie rope hook 10 is attached to the outer frame material 6 that constitutes the bogie body 2 as a loading platform. Since the rope hook 10 is attached to the side edge of the bogie body 2, for convenience of explanation, the front of the rope hook 10 is synonymous with the side of the bogie 1.

[0026] As shown in Figures 4 to 8, the rope hooking device 10 consists of an attachment plate 11 attached to the outer surface of the outer frame material 6 that constitutes the bogie body 2, a hooking member 12 made of a round bar bent into a U-shape and both ends of which are attached to the attachment plate 11, and a separate member 13 that is arranged to bridge the centers of the attachment plate 11 and the hooking member 12.

[0027] The mounting plate 11, hooking member 12, and separating member 13 are made of, for example, an aluminum alloy, with the mounting plate 11 being an L-shaped angle, the hooking member 12 being a round bar, and the separating member 13 being a plate, and each member being joined by welding or the like.

[0028] The hook member 12 is formed by bending it into a U-shape and consists of mounting portions 14 whose both ends are welded to the mounting plate 11, and a hook portion 15 that faces parallel to the mounting plate 11. When the mounting portions 14 on both ends are attached to the mounting plate 11, a space 16 is formed between the mounting plate 11 and the hook member 12.

[0029] The separate member 13 has both ends welded to each other so as to bridge the center of the mounting plate 11 in the left-right direction (with respect to the rope hook 10) and the center of the hooking part 15 in the left-right direction (with respect to the rope hook 10), thereby dividing the space 16 and forming two insertion holes 17. The insertion holes 17 are large enough to allow the rope to pass through.

[0030] Such a rope hook 10 has mounting plates 11 riveted to the outer frame material 6 at two locations spaced apart from each other at the front and rear of the outer frame material 6 (relative to the bogie 1).

[0031] Furthermore, a hook 20 is attached to the side edge (outer frame material 6) in the short side direction of the bogie body 2, approximately in the center thereof. Unlike the rope hook 10, this hook 20 is formed by bending a rod material into a U-shape, and does not have any separate members. This is because the vibration and impact of the transported object are small in the short side direction. Of course, the rope hook 10 can also be attached to the side edge of the bogie body 2 in the short side direction.

[0032] When such a rope hook 10 is used to secure an object to be transported with a rope, one end of the rope is fixed to one of the rope hooks 10 by using its insertion hole 17, the rope is wound around the object to be transported, and the rope is hooked into the insertion hole 17 of the rope hook 10 on the opposite side.

[0033] In this way, the rope can be wound around the transported object while being hooked onto the rope hooking device 10, and the rope end can be hooked onto another rope hooking device 10 and tightened, thereby securing the transported object.

[0034] At this time, since the rope hook 10 has two adjacent insertion holes 17, it is possible to select the insertion hole 17 that is deemed best for securing the transported object.

[0035] Even if the transported object shifts due to vibration or impact during transportation, the rope will not shift from the hooked position because the insertion hole 17 of the rope hooking device 10 that hooks the rope is narrow, and therefore the secured state of the transported object can be maintained.

[0036] Because the rope hook 10 according to the above embodiment is equipped with the mounting plate 11, it can be attached to an existing cart simply by attaching the mounting plate 11 to the side edge of the cart body 2 serving as the loading platform (in this embodiment, the outer frame material 6). Furthermore, even if a cart already has a hook, if the position of the hook is not appropriate, the rope hook 10 according to this embodiment can be easily attached and the rope can be hooked at the desired position. In short, the rope hook 10 according to the present invention can be easily attached to an existing loading platform as a retrofit.

[0037] The rope hook 10 according to the above embodiment is described as having one separate member 13, but the present invention is not limited to this and multiple separate members may be provided. By providing multiple rope hooks 10, the number of points at which the rope can be hooked increases, making it possible to secure the transported object in an appropriate position and also making it possible to secure the transported object with an irregular shape.

[0038] As described above, in the rope hooking device 10 of the present invention, the C-shaped or U-shaped hooking member 12 is attached to the side edge of the loading platform (the outer frame material 6 of the cart body 2), so that the hooking portion 15 extends in a direction along the side edge of the loading platform, and the separate member 13 divides the space 16 between the hooking member 12 and the loading platform, forming at least two insertion holes 17, so that the hooking position of the rope can be appropriately selected in the direction in which the side edge of the loading platform extends, allowing for flexible fastening of transported goods.

[0039] In addition, since the space between the hooking member 12 and the loading platform is divided by the separate member 13, the position where the rope is hooked does not move even when subjected to vibration or impact during transportation, so that the fastening of the transported goods does not loosen and the load can be prevented from collapsing.

[0040] In other words, by providing the separate member 13, the spacing between the insertion holes 17 can be reduced, the rope does not move, and even if the transported goods move slightly due to the vibrations and impacts caused by the movement of the cart 1, the hooking position of the rope remains fixed and the rope does not loosen.As a result, the rope does not come off the transported goods, preventing the cargo from falling over.

[0041] Furthermore, in the rope hooking device 10 according to the above embodiment, an attachment plate 11 is provided, so that the hooking member 12 including the attachment plate 11 can be made into a single component, and can be retrofitted to an existing cargo bed.

[0042] If such a mounting plate 11 is not provided, the mounting portion 14 of the hook member 12 and the separate member 13 may be directly attached to the loading platform (outer frame material 6).

[0043] In addition, although the mounting plate 11 is attached to the outer frame material 6 by rivets, the present invention is not limited to this, and mechanical joining by screws, bolts, etc. Furthermore, although the joining between other components has been described as welding, the joining is not limited to this, and material joining by brazing, soldering, etc. is also possible.

[0044] Furthermore, the hooking member 12 has been described as being formed by bending a round bar material into a U-shape, but the present invention is not limited to this, and it may also be formed by bending a square bar material or bending it into a U-shape.

[0045] In the above embodiment, the separating member 13 is described as a plate material, but is not limited to this and may be a round bar material.

[0046] Although the embodiments of the present invention have been described above, the specific configuration is not limited to the above embodiments, and design changes that do not deviate from the gist of the present invention are also included in the present invention. For example, although the term "rope hook" is used, it is not limited to ropes, but can also be applied to hooks for binding materials such as belts and strings. Furthermore, while the above embodiments have described a dolly 1 equipped with casters 3, the present invention is not limited to this and can be applied to bicycle carriers, cargo trays, and other items on which transported items are placed and secured with ropes.

[0047] Furthermore, in the above embodiment, the rope hook 10 is formed / constructed by joining multiple members, namely the mounting plate 11, the hooking member 12, and the separate member 13, by welding or the like, but the rope hook 10 may also be constructed such that the joint portion 31, the rope engagement portion 32, and the separate member 33 are integrally formed (for example, cast as a single piece from an aluminum alloy) as shown in Figures 9 to 11. The mounting plate 11 in the above embodiment corresponds to the joint portion 31, the hooking member 12 corresponds to the rope engagement portion 32, and the separate member 13 corresponds to the separate member 33.

[0048] In this case, the rope hook 10 is configured to include a joint 31 for attachment to the side edge of the loading platform on which the transported goods are placed, a hook 15 on which the end or middle part of the rope for securing the transported goods is hooked, a C-shaped or U-shaped rope engagement part 32 having an attachment part 14 connected to the joint 31, and a separate part 33 that is bridged between the middle part of the hook 15 and the joint 31 to divide the space 16 between the rope engagement part 32 and the joint 31 and form at least two insertion holes 17.

[0049] The joint 31 consists of a side plate portion 31a that runs along a vertical plane and a bottom plate portion 31b that runs along a horizontal plane, and the bottom plate portion 31b is connected to the lower end of the side plate portion 31a, forming an L-shape when viewed from the side of the rope hook 10 (see Figure 11).

[0050] The rope engagement portion 32 is formed in a U-shape (or may be U-shaped) in a planar view (see Figure 10), and comprises an attachment portion 14 whose ends (specifically, the ends of a pair of parallel opposing sides of the U-shape) connect to the joint 31, and a hook portion 15 that faces parallel to the joint 31.When the attachment portion 14, which is a pair of parallel opposing sides of the U-shape, connects to the joint 31, a space 16 is formed between the joint 31 and the rope engagement portion 32.

[0051] The separate portion 33 is connected at both ends in the front-to-rear direction (with respect to the rope hook 10) so as to bridge the center portion in the left-to-right direction (with respect to the rope hook 10) of the joint portion 31 and the center portion in the left-to-right direction (with respect to the rope hook 10) of the hook portion 15, thereby dividing the space 16 and forming two insertion holes 17. These insertion holes 17 are sized to allow the rope to be inserted therethrough.

[0052] The rope hooking device 10 is attached to the outer surface of the outer frame material 6, which constitutes the bogie body 2, at two locations spaced apart in the front and back (from the bogie 1 perspective), by, for example, riveting it through two through holes 311 spaced apart on the left and right (from the rope hooking device 10 perspective) in the side plate portion 31a of the joint 31 in the position when attached to the bogie 1 (furthermore, fastened to the side of the outer frame material 6), and by, for example, riveting it through two through holes 312 spaced apart on the left and right (from the rope hooking device 10 perspective) in the bottom plate portion 31b of the joint 31 (furthermore, fastened to the bottom surface of the outer frame material 6).

[0053] According to the above-described rope hook 10, the C-shaped or U-shaped rope engagement portion 32 is provided on the side edge of the loading platform (specifically, the outer frame material 6 of the dolly body 2), so that the hooking portion 15 extends in a direction along the side edge of the loading platform, and the separate portion 33 divides the space 16 between the rope engagement portion 32 and the loading platform to form at least two insertion holes 17, so that the hooking position of the rope can be appropriately selected in the direction in which the side edge of the loading platform extends, allowing for flexible fastening of the transported object. Furthermore, because the separate portion 33 divides the space between the rope engagement portion 32 and the loading platform, the hooking position of the rope does not move even with vibrations or shocks during transport, so that the fastening of the transported object does not loosen and the load can be prevented from falling over.
