Description

[Technical field]

[0001] The present invention relates to a vehicle cargo hanging device that is fixed to a fixed surface provided inside a vehicle. [Background technology]

[0002] A vehicle may be provided with a vehicle cargo hooking device for hanging a cargo handle, hook, or other cargo hook. For example, the following Patent Document 1 describes a hook device having a holding member attached to a workpiece and a hook member rotatably held by the holding member. The hook member has a rotation shaft that is rotatably supported by the holding member, and a hooking portion connected to the rotation portion. The hook member is rotated and raised to project the hooking portion from the recess of the workpiece, and then the cargo handle, hook, or other cargo hook is hooked onto the hooking portion.

[0003] Also, a vehicle cargo hanging device is known that includes, for example, a metal bracket with insertion holes formed on both sides and fixed to the interior of the vehicle, a housing attached to the metal bracket, and a metal shaft that is inserted and supported through the insertion holes and exposed inside the vehicle. In the case of such a vehicle cargo hanging device, a hook or the like is hung on the shaft that is exposed inside the vehicle. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2006-46548 A Summary of the Invention [Problem to be solved by the invention]

[0005] In a vehicle cargo hanging device having a metal shaft as described above and exposed inside the vehicle cabin, when the shaft is inserted into the insertion hole of the metal bracket, the shaft abuts against the inner circumference of the insertion hole and is easily damaged. A shaft with a damaged outer circumference has an exposed middle part between both ends supported by the insertion hole and visible to passengers (exposed inside the vehicle cabin), which makes it look unattractive.

[0006] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a vehicle cargo hanging device that can suppress damage to the outer periphery of the shaft and improve the appearance. [Means for solving the problem]

[0007] In order to achieve the above object, the present invention provides a vehicle cargo hanging device that is fixed to a fixed surface provided inside a vehicle, the vehicle cargo hanging device having a base member, a metal bracket that is attached to the base member and fixed to the fixed surface via a fastener, and a shaft having a cargo hanging portion, the base member having a bottom wall and a side wall extending upright from the bottom wall, a first shaft insertion hole through which the shaft is inserted is formed in each of opposing surfaces of the side walls, the metal bracket having a fixing plate disposed outside the bottom wall and a metal bracket extending upright from opposing sides of the fixing plate, The side wall has a pair of support plates arranged outside the first shaft insertion hole, and a second shaft insertion hole is formed in the support plates so as to align with the first shaft insertion hole and through which the shaft is inserted, the first shaft insertion hole has an inner dimension smaller than the inner dimension of the corresponding second shaft insertion hole, and the portion of the shaft that is inserted into the first shaft insertion hole and the second shaft insertion hole has an outer dimension larger than the inner dimension of the first shaft insertion hole and smaller than the inner dimension of the second shaft insertion hole. Effect of the Invention

[0008] According to the present invention, the first shaft insertion hole has an inner dimension smaller than that of the corresponding second shaft insertion hole, and the portion of the shaft inserted into the first shaft insertion hole and the second shaft insertion hole has an outer dimension larger than that of the first shaft insertion hole and smaller than that of the second shaft insertion hole, so that when the shaft is inserted into the first shaft insertion hole and the second shaft insertion hole, the outer periphery of the shaft mainly comes into sliding contact with the inner periphery of the first shaft insertion hole and is less likely to come into sliding contact with the inner periphery of the second shaft insertion hole. As a result, damage to the outer periphery of the shaft can be suppressed and the appearance can be improved. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] (One embodiment of a vehicle cargo hanging device) DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a vehicle cargo hanging device according to the present invention will be described with reference to the drawings.

[0011] As shown in FIG. 11, this vehicle cargo hanging device 10 (hereinafter simply referred to as "cargo hanging device 10") is fixed to a fixed surface 1 provided inside a vehicle via a fixing device 7, and a luggage handle or hook 5, etc. is hung on it (in this embodiment, a hook 5 is hung on it).

[0012] The hook 5 is attached to the end of a belt, rope, etc. provided inside the vehicle, and is used, for example, to keep the third row of seats in an upright position in a vehicle with three rows of seats, or to hold luggage stored in the luggage compartment.

[0013] In this embodiment, the fixed surface 1 is the passenger compartment side surface of a side panel arranged on a side surface inside the vehicle. However, the fixed surface may be a surface other than the side surface of the vehicle, such as a ceiling surface or a floor surface.

[0014] Furthermore, as shown in Figure 10, the fixed surface 1 is formed with a fixed hole 2 into which a fastener 7 is fixed, a first insertion hole 3 located below the fixed hole 2, and a second insertion hole 4 located above the fixed hole 2.

[0015] The fixing device 7 is a screw having a head 7a into which the tip of a tool such as a screwdriver (not shown) fits, and a shaft 7b extending from the center of the back surface of the head 7a and having a threaded groove formed on the outer periphery. The fixing device may be a bolt or the like as long as it can fix the vehicle load hanging device to the surface to be fixed.

[0016] As shown in Figures 1 and 2, the load hanging device 10 is mainly composed of a base member 20, a metal bracket 50 (hereinafter simply referred to as "bracket 50") that is attached to the base member 20 and fixed to the fixed surface 1 via a fastener 7, a lid 60 that is rotatably attached to the base member 20 and covers the fastener 7, and a shaft 70 that has a load hanging portion and to which the hook 5 is hung.

[0017] The base member 20 has a bottom wall 21 and side walls (a pair of first side walls 23, 23 and a pair of second side walls 24, 24) standing upright from the bottom wall 21, and first shaft insertion holes 43, 44 through which the shaft 70 is inserted are formed on the opposing surfaces of the first side walls 23, 23. The base member 20 will be described in detail later.

[0018] In the following description, the direction in which the pair of first side walls 23, 23 are arranged is referred to as the "width direction X," and the direction perpendicular to this width direction X is referred to as the "depth direction Y" (the same applies to the bracket 50, the lid 60, etc.).

[0019] Moreover, the bracket 50 has a fixed plate 51 and a pair of pivot support plates 52, 52 standing upright from the fixed plate 51, and second shaft insertion holes 53, 53 are formed in the pair of pivot support plates 52, 52. The bracket 50 will be described in detail later.

[0020] Furthermore, the shaft 70 has an axial portion 71 having a base end 74 and a tip end 75, and a head portion 73 connected to the base end 74 of the axial portion 71. The details of the shaft 70 will be described later. The axial portion 71 forms the "load-hanging portion" of the present invention.

[0021] First, the bracket 50 will be described in detail.

[0022] The fixing plate 51 constituting the bracket 50 is in the form of a long plate extending a predetermined length, and has a pair of long sides 51a, 51a and a pair of short sides 51b, 51b arranged perpendicular to the pair of long sides 51a, 51a. As shown in Fig. 4, the fixing plate 51 is arranged on the outer side of the bottom wall 21 of the base member 20 (the side facing the fixed surface 1).

[0023] Further, a pair of pivot support plates 52, 52 are provided standing from a pair of oppositely disposed short sides 51b, 51b of the fixed plate 51.

[0024] 1, 2, 5, and 7, the pair of pivot plates 52, 52 are made up of bases 52a, 52a erected so as to widen slightly outward from the short sides 51b, 51b of the fixed plate 51, and tip portions 52b, 52b connected to the ends of the bases 52a, 52a and arranged parallel to each other. When viewed from the side, each pivot plate 52 has a substantially trapezoidal plate shape in which the base 52a is wide and the tip portion 52b is narrower than the base 52a (see FIG. 5).

[0025] 7, the pair of pivot support plates 52, 52 are arranged on the outsides of the first shaft insertion holes 43, 44 of the first side walls 23, 23 of the base member 20. Here, the pair of pivot support plates 52, 52, particularly the tip portions 52b, 52b, are arranged on the outsides of the portions of the first side walls 23, 23 of the base member 20 where the first shaft insertion holes 43, 44 are formed.

[0026] Further, circular second shaft insertion holes 53, 53 are formed in the tip ends 52b, 52b of the pair of shaft support plates 52, 52. The pair of second shaft insertion holes 53, 53 are arranged to align with the pair of first shaft insertion holes 43, 44 provided in the base member 20 (see FIG. 7), and the shaft 70 is inserted through these shaft insertion holes 43, 44, 53, 53 (see FIG. 8).

[0027] 1 and 2, a rotation restricting piece 54 protrudes from a middle portion in the width direction X on one long side 51a side of the fixed plate 51. The rotation restricting piece 54 has a wide portion 54a with tapered side surfaces on the base side, and a tip portion 54b that protrudes with a constant width from the wide portion 54a and is bent so as to form a substantially L-shape. The tip portion 54b of the rotation restricting piece 54 fits into the rotation restricting recess 30 of the base member 20, thereby restricting the rotation of the bracket 50 with respect to the base member 20 (see FIG. 4).

[0028] Further, a pair of claws 55, 55 protrude from both sides of the rotation restricting piece 54 on one long side 51a of the fixing plate 51. Each claw 55 has a shape that protrudes while being bent in a stepped manner. The pair of claws 55, 55 are inserted into a pair of insertion holes 28, 28 of the base member 20, whereby the bracket 50 is positioned and fixed to the base member 20 (see FIG. 4).

[0029] Furthermore, a substantially elongated fastener insertion hole 56 (a hole extending slightly in the depth direction Y) is formed on one long side 51a of the fixing plate 51 at a position aligned with the rotation restricting piece 54. The shaft 7b of the fastener 7 is inserted into this fastener insertion hole 56, and the head 7a of the fastener 7 engages with the inner peripheral edge of the fastener insertion hole 56 (the peripheral edge on the surface facing the bottom wall 21 of the base member 20) (see FIG. 10).

[0030] Furthermore, a generally U-shaped notch 57 is formed in the middle of the fixing plate 51 in the width direction X on the other long side 51a side. The positioning pin 31 of the base member 20 fits into this notch 57, and the bracket 50 is positioned and fixed to the base member 20 (see FIG. 4).

[0031] The bracket 50 described above is formed by punching out and bending a plate material made of a predetermined metal material into a predetermined shape, and all parts (fixed plate 51, pivot support plate 52, rotation restriction piece 54, claw portion 55, etc.) are integrally formed.

[0032] Next, the base member 20 will be described in detail.

[0033] As described above, the base member 20 has the bottom wall 21 and the side walls 23, 24, and is formed with the first shaft insertion holes 43, 44 (see FIG. 1). Referring also to FIG. 2, the bottom wall 21 has a substantially rectangular (quadrilateral) shape with a plurality of recesses on its outer surface, and the fixing plate 51 of the bracket 50 is disposed on the outer side thereof.

[0034] A pair of first side walls 23, 23 stand upright from a pair of predetermined opposing side edges of the bottom wall 21. A pair of pivot support plates 52, 52 of the bracket 50 are disposed outside the pair of first side walls 23, 23 (see FIG. 7). In addition, a pair of second side walls 24, 24 stand upright from another pair of side edges of the bottom wall 21 that are disposed perpendicular to the pair of predetermined side edges on which the pair of first side walls 23, 23 stand upright.

[0035] The ends of the adjacent side walls 23, 24 are connected to each other, and the four side walls 23, 24 form a generally rectangular frame-like portion that is open at the top (the side facing the bottom wall 21). It can also be said that the entire base member 20 is generally rectangular box-like with a bottom and an open top.

[0036] 2 and 4, the rectangular frame-shaped portion formed by the four side walls 23 has a shape in which the upper opening side gradually becomes larger relative to the bottom wall 21 side. That is, the side walls 23, 24 do not stand upright in the plane direction of the bottom wall 21, but stand at a slightly inclined angle diagonally outward from the bottom wall 21 toward the upper opening side (see FIGS. 8 and 10).

[0037] Furthermore, a flange portion 25 having a generally rectangular ring shape projects from the outer periphery of the tip portion in the erecting direction of each of the side walls 23, 24. This flange portion 25 is adapted to engage with the periphery of a recess in a trim member or the like (not shown) that is disposed on the interior side of the fixed surface 1.

[0038] A fastener insertion hole 27 through which the fastener 7 is inserted is formed at a predetermined position of the bottom wall 21. The fastener insertion hole 27 is arranged so that the shaft portion 7b of the fastener 7 is inserted and the head portion 7a of the fastener 7 can be exposed, allowing the tip of a tool (not shown) to be fitted into the head portion 7a. The inner diameter of the fastener insertion hole 27 is smaller than the outer diameter of the head portion 7a of the fastener 7 to prevent the fastener 7 from falling off.

[0039] 2, a pair of insertion holes 28, 28 are formed on the outer surface of the bottom wall 21 (the surface facing the fixed surface 1) on the inside of both sides in the width direction X of one of the second side walls 24. Each of the claw portions 55 of the bracket 50 is inserted into each of the insertion holes 28, so that the bracket 50 is positioned and fixed to the base member 20 (see FIG. 4).

[0040] Furthermore, a pair of locking holes 29, 29 are formed on the outer surface of the bottom wall 21 at positions adjacent to the pair of insertion holes 28, 28. A pair of locking claws 67, 67 of the lid 60 are adapted to be releasably locked into each of the locking holes 29 (see FIG. 4), and the lid 60 is adapted to lock the fixing tool insertion holes 27 and the fixing tool insertion holes 56 in a closed state.

[0041] Further, a rotation restricting recess 30 is formed in the outer surface of the bottom wall 21 at the middle portion in the width direction X of the side on which the one second side wall 24 is located. The tip portion 54b of the rotation restricting piece 54 of the bracket 50 fits into this rotation restricting recess 30, thereby restricting the rotation of the bracket 50 relative to the base member 20 (see FIG. 4).

[0042] Furthermore, a positioning pin 31 protrudes from the middle part in the width direction X of the outer surface of the bottom wall 21 on which the other second side wall 24 is located. The positioning pin 31 fits into a notch 57 of the bracket 50, thereby positioning and fixing the bracket 50 to the base member 20 (see FIG. 4).

[0043] 1 and 2, a through groove 33 is formed in the bottom wall 21 at a position closer to the other second side wall 24, penetrating the bottom wall 21 along the width direction X. Furthermore, a pair of shafts 35, 35 extending parallel to the through groove 33 are formed with a gap 34 interposed therebetween at both sides of the bottom wall 21 in the width direction X, adjacent to the through groove 33. A bearing 63 of the lid 60 is supported by each shaft 35.

[0044] In addition, a notch 36 communicating with the through groove 33 is formed in the bottom wall 21 between the pair of shaft portions 35, 35 in the middle portion in the width direction X (see Figures 1 and 2), and a flexible elastic piece 37 capable of flexibly deforming is provided through the notch 36 (see Figure 10).

[0045] 2, a protruding portion 41 is provided on the outer surface (the surface opposite to the opposing surface of each side wall) of the pair of first side walls 23, 23. This protruding portion 41 is located on the outer surface of each first side wall 23, near the other second side wall 24, and is generally trapezoidal in shape protruding by a predetermined height from a position adjacent to the flange portion 25.

[0046] As shown in FIG. 2, raised portion 41 has a trapezoidal shape with a larger lower base on the bottom wall 21 side and a smaller upper base on the flange portion 25 side. In accordance with the shape of first side wall 23 that is inclined with respect to the surface direction of bottom wall 21, raised portion 41 is thick on the bottom wall 21 side and gradually becomes thinner on the flange portion 25 side, and the outer surface (the tip surface in the raised direction) is flat and perpendicular to the surface direction of bottom wall 21.

[0047] The first shaft insertion holes 43, 44, through which the shaft 70 is inserted, are formed on the opposing surfaces of the first side walls 23, 23, respectively, in the portion of the first side wall 23 where the raised portion 41 is provided.

[0048] 2 and 7, a first shaft insertion hole 43 is formed in a portion of one first side wall 23 where the raised portion 41 is provided. Also, as shown in Fig. 7, a first shaft insertion hole 44 is formed in a portion of the other first side wall 23 where the raised portion 41 is provided. That is, the first shaft insertion holes 43, 44 are formed in the thick portion of the first side walls 23, 23 where the raised portion 41 is provided, rather than in the portion of the first side walls 23, 23 where the raised portion is not formed.

[0049] The first shaft insertion holes 43, 44 are formed at positions aligned with each other in the width direction X, the depth direction Y, and the height direction, and the shaft portion 71 of the shaft 70 can be inserted and supported therethrough.

[0050] Each of the first shaft insertion holes 43, 44 is a round hole having a circular shape. In addition, as shown in Fig. 2, a tapered surface 45 is formed on the inner peripheral edge portion of the first shaft insertion hole 43 on the outer side in the thickness direction (direction along the width direction X) of the first side wall 23.

[0051] 7, the tip portion 75 of the shaft portion 71 of the shaft 70 is inserted from the side of the first shaft insertion hole 43. More specifically, the shaft portion 71 of the shaft 70 is inserted from the tip portion 75 side through one of the second shaft insertion holes 53 of the bracket 50, the first shaft insertion hole 43 of the base member 20, the first shaft insertion hole 44 of the base member 20, and the other second shaft insertion hole 53 of the bracket 50, in this order.

[0052] The direction in which the shaft 70 is inserted into the shaft insertion holes 43, 44, and 53 is referred to as a "shaft insertion direction F" (see FIG. 7).

[0053] As described above, when the shaft 70 is inserted into the first shaft insertion hole 43 from the tip portion 75 side, the tapered surface 45 makes it easier to insert the tip portion 75 of the shaft portion 71 into the first shaft insertion hole 43.

[0054] Also, as shown in Figures 1 and 7, on the side through which the axial tip 75 of the shaft 70 is inserted, i.e., on the inner circumference of the other first shaft insertion hole 44, a plurality of ribs 46 are formed in the circumferential direction, which are crushed and deformed when the tip 75 of the shaft 70 is inserted.

[0055] In this embodiment, as shown in Figures 1, 7 and 9, multiple (here, three) ribs 46, which protrude from the inner circumference of the first shaft insertion hole 44 at a predetermined height and extend along the shaft insertion direction F, are formed on the inner circumference of the first shaft insertion hole 44 at equal intervals in the circumferential direction.

[0056] Each rib 46 is provided over the entire thickness direction of the first side wall 23, including the raised portion 41; in other words, each rib 46 is provided over the entire axial direction of the first shaft insertion hole 44 (see FIG. 7).

[0057] Furthermore, as shown in FIG. 9, when the first shaft insertion hole 44 is viewed in the axial direction, each rib 46 is a roughly triangular protrusion that is wide on the inner periphery of the first shaft insertion hole 44 and gradually narrows toward the center of the insertion hole (a triangular protrusion that is wide on the base end side and narrow at the apex).

[0058] When the tip 75 of the shaft 70 is inserted into the inside of the first shaft insertion hole 44, the top of each rib 46 is pressed and crushed by the outer periphery of the tip 75, so that the rib 46 fits closely to the outer periphery of the tip 75 of the shaft 70.

[0059] Moreover, the first shaft insertion holes 43, 44 have smaller inner dimensions (are formed with smaller inner dimensions) than the inner dimensions of the corresponding second shaft insertion holes 53, 53.

[0060] Here, since each of the shaft insertion holes 43, 44, 53 is a circular hole, the inner dimension of each of them means the inner diameter. Also, the inner diameter of the first shaft insertion hole 44 provided with the multiple ribs 46 is the inner diameter including the ribs 46, and specifically means the inner diameter of an imaginary circle passing through the tops of the multiple ribs 46.

[0061] As shown in FIG. 7, one of the first shaft insertion holes 43 is formed with an inner diameter D1 smaller than the inner diameter D2 of the corresponding second shaft insertion hole 53 provided in the bracket 50, and the other first shaft insertion hole 44 is also formed with an inner diameter D1 smaller than the inner diameter D2 of the corresponding second shaft insertion hole 53 provided in the bracket 50 (D2>D1).

[0062] In addition, the inner dimension means the inner diameter when the shaft insertion hole is a circular hole, as in this embodiment, but when the shaft insertion hole is a rectangular hole, for example, it means the largest inner dimension (maximum inner dimension).

[0063] 2 and 4, the pair of first side walls 23 are provided with positioning portions 48 that position the first shaft insertion hole 43 and the second shaft insertion hole 53 so that they are concentric (so that the radial centers of the shaft insertion holes 43 coincide). Furthermore, an engagement portion is provided between the base member 20 and the metal bracket 50, which engages the fixed plate 51 and the bottom wall 21 with each other in a state in which the first shaft insertion hole 43 and the second shaft insertion hole 53 are positioned so that they are concentric.

[0064] Each positioning portion 48 consists of a first protrusion 48a that protrudes from the outer surface of the raised portion 41 provided on the first side wall 23 and extends along the flange portion 25, and a second protrusion 48b that protrudes from the outer surface of the raised portion 41, inclines diagonally outward relative to the first protrusion 48a from one end in the extension direction of the first protrusion 48a, and extends along one side edge of the raised portion 41, and is approximately L-shaped when viewed from the side.

[0065] The inner circumferential surface of the connecting portion between the first protrusion 48a and the second protrusion 48b is an arc-shaped curved surface that fits the outer circumferential shape of the shaft portion 71 of the shaft .

[0066] Incidentally, when mounting the bracket 50 on the base member 20, the bracket 50 is pressed into the base member 20 in the direction indicated by the arrow G in Fig. 5. Specifically, the pair of claw portions 55, 55 are inserted into the pair of insertion holes 28, 28, and then the bracket 50 is pressed into the base member 20.

[0067] Then, the tip portions 52b of the pivot plates 52 of the bracket 50 come into contact with the inner peripheries of the first and second protrusions 48a, 48b of each positioning portion 48, restricting further pushing of the bracket 50 into the base member 20. In other words, the positioning portions 48 function as push-in stoppers.

[0068] As described above, when the support plate 52 of the bracket 50 abuts against the positioning portion 48, the first shaft insertion hole 43 and one of the second shaft insertion holes 53 are positioned so as to be concentric, and the first shaft insertion hole 44 and the other second shaft insertion hole 53 are positioned so as to be concentric.

[0069] Furthermore, when the first shaft insertion hole 43, 44 and the second shaft insertion hole 53, 53 are positioned so as to be concentric, the pair of claw portions 55, 55 of the bracket 50 are fully inserted into the pair of insertion holes 28, 28 of the base member 20, whereby the fixing plate 51 of the bracket 50 and the bottom wall 21 of the base member 20 engage with each other.

[0070] The base member 20 described above is made of a predetermined synthetic resin material that is at least lower in hardness and rigidity than the metal material from which the shaft 70 is made.

[0071] Next, the lid 60 will be described in detail.

[0072] The lid 60 in this embodiment has an approximately rectangular plate shape (approximately a square plate shape) and has a cover portion 61 that covers the fastener insertion hole 27 of the base member 20 and the fastener insertion hole 56 of the bracket 50, and a pair of bearing portions 63, 63 that protrude from the cover portion 61 and rotatably support a pair of shaft portions 35, 35 of the base member 20, making it possible to open and close the fastener insertion hole 27 and the fastener insertion hole 56.

[0073] Specifically, as shown in FIG. 2, a pair of bearing portions 63, 63 are provided on the inner surface side of the cover portion 61 (the surface side facing the bottom wall 21 of the base member 20), on both sides in the width direction X and on the other side in the depth direction Y.

[0074] A protrusion 66 is provided on the other side in the depth direction Y of the inner surface of the cover portion 61 between the pair of bearing portions 63, 63. When the lid 60 opens relative to the fixing tool insertion holes 27 and 56, the protrusion 66 engages with the elastic piece 37 of the base member 20 to hold the lid 60 in the open state.

[0075] Furthermore, a pair of locking claws 67, 67 are provided on the inner surface of the cover portion 61, on both sides in the width direction X and on one side in the depth direction Y. When the lid 60 closes the fastener insertion hole 27 and the fastener insertion hole 56, it engages with a pair of locking holes 29, 29 of the base member 20, locking the fastener insertion hole 27 and the fastener insertion hole 56 in a closed state.

[0076] Next, the shaft 70 will be described in detail.

[0077] This shaft 70 is formed from a specified metal material and has a round bar-shaped shaft portion 71 (constituting the ``load-hanging portion'' in this invention) with a circular outer periphery that extends straight a specified length, and a circular plate-shaped head portion 73 that is connected to a base end portion 74 (which can also be said to be one end portion) of the shaft portion 71 and has a larger diameter than the outer diameter of the shaft portion 71.

[0078] A mounting groove 75a, into which a retaining ring (E-ring) 9 is mounted, is formed on the outer periphery of a tip end 75 (which can also be called the other end) of the shaft portion 71. The portion between both ends 74, 75 of the shaft portion 71 forms an intermediate portion 76.

[0079] 8, a base end 74 of the shaft 71 is inserted into the first shaft insertion hole 43 of the base member 20, and is also inserted into one of the second shaft insertion holes 53 of the bracket 50. In addition, the head 73 engages with the outer peripheral edge of the second shaft insertion hole 53 of one of the pivot support plates 52 of the bracket 50.

[0080] Furthermore, the tip portion 75 of the shaft portion 71 is inserted into the inside of the first shaft insertion hole 44 of the base member 20 and is also inserted into the inside of the other second shaft insertion hole 53 of the bracket 50 .

[0081] Furthermore, while the tip end 75 of the shaft portion 71 is inserted into the inside of the first shaft insertion hole 44, the ribs 46 provided on the inner circumference of the first shaft insertion hole 44 are pressed and deformed to be in close contact with the outer circumference of the tip end.

[0082] Furthermore, an expanded diameter portion 77 having a diameter larger than the outer diameter of the shaft portion 71 is provided on the outer periphery of the base end portion 74 of the shaft portion 71. Although not shown in the figure, the outer periphery of this expanded diameter portion 77 is knurled with a twill, oblique, flat, or other knurling.

[0083] When the base end 74 of the shaft portion 71 is inserted into the first shaft insertion hole 43, the expanded diameter portion 77 is pressed against the inner periphery of the first shaft insertion hole 43. That is, the base end 74 of the shaft portion 71 is also pressed into the first shaft insertion hole 43.

[0084] In addition, the shaft 70 has both ends 74, 75 of its shaft portion 71 penetrating the opposing surfaces of the first side walls 23, 23 and supported by the shaft support plates 52, 52 of the bracket 50, and the middle portion 76 of the shaft portion 71 is positioned between the opposing surfaces of the first side walls 23, 23.

[0085] The shaft 70 has a portion that is inserted into the first shaft insertion hole 43, 44 and the second shaft insertion hole 53, 53, and this portion has outer dimensions that are larger than the inner dimensions of the first shaft insertion hole 43, 44 and smaller than the inner dimensions of the second shaft insertion hole 53, 53 (is formed with smaller outer dimensions).

[0086] In the shaft 70, the portion that is inserted into and supported by the first shaft insertion holes 43, 44 and the second shaft insertion holes 53, 53 constitutes the shaft portion 71. Since the shaft portion 71 has a round bar shape with a circular outer periphery, its outer dimension is the outer diameter, and this outer diameter is designated as D3.

[0087] The shaft portion 71 of the shaft 70 is formed with an outer diameter D3 that is larger than the inner diameter D1 of the first shaft insertion holes 43, 44 of the base member 20 and smaller than the inner diameter D2 of the second shaft insertion holes 53, 53 of the bracket 50 (D2>D3>D1).

[0088] In addition, the outer dimension means the outer diameter when the shaft portion is a round bar, as in this embodiment, but when the shaft portion is a square bar, for example, the outer dimension means the largest outer dimension (maximum outer dimension).

[0089] In addition, in this load hanging device 10, when a load is applied to the shaft 70 from the hook 5, the base member 20 is configured to be able to move via the shaft 70 until the shaft 70 abuts against the inner circumference of the second shaft insertion hole 53, 53 (see the dotted line in Figure 12).

[0090] In this embodiment, when the hook 5 is hooked on the shank 71 forming the load-hanging portion of the shaft 70 (see FIG. 11) and a load from the hook 5 acts on the shank 71 as indicated by the arrow P in FIG. 12, the shank 71 comes into partial contact with the inner periphery of the first shaft insertion holes 43, 44 of the base member 20. Here, the shank 71 comes into contact with the inner periphery located below the page surface of the first shaft insertion holes 43, 44 in FIG. 12, and a load is applied in a direction that presses the base member 20 down.

[0091] As a result, the entire base member 20 moves slightly in the direction in which it is pressed downward (this can also be said to move slightly or shift in position), so that, as shown by the dotted line in Figure 12, the axial portion 71 of the shaft 70 abuts against the inner circumference of the second shaft insertion hole 53 of the bracket 50, which is located below the page surface.

[0092] (Modification) The shape, structure, layout, etc. of each part of the base member, metal bracket, lid, and shaft are not particularly limited.

[0093] The base member 20 in this embodiment is in the shape of a roughly rectangular box with a bottom and an open top; however, the base member may also be in the shape of, for example, a roughly C-shaped or U-shaped frame with a portion of the side open, as long as it has a bottom wall and a pair of side walls.

[0094] Although the first shaft insertion hole and the second shaft insertion hole are circular holes, these shaft insertion holes may be rectangular holes such as square or hexagonal holes, or elliptical holes as long as the shaft can be inserted and supported. The outer circumferential shape of the axial portion of the shaft is preferably a shape that fits the inner circumferential shape of the shaft insertion hole.

[0095] Furthermore, the number of ribs provided on the inner circumference of the first shaft insertion hole may be two, or four or more. The outer surface shape of the ribs may be curved, trapezoidal, or the like, and may not extend along a protrusion but may be provided within a predetermined range in the thickness direction of the side wall, as long as they can be crushed and deformed when the shaft is inserted into the first shaft insertion hole.

[0096] (Action and effect) Next, the function and effect of the load hanging device 10 having the above-mentioned configuration will be described.

[0097] When assembling the load hanging device 10 by attaching the base member 20, bracket 50, lid 60, shaft 70, etc., the following procedure is carried out, for example.

[0098] First, the shaft portion 7b of the fastener 7 is inserted into the fastener insertion hole 56 of the bracket 50, and the head portion 7a of the fastener 7 is engaged with the inner peripheral portion of the fastener insertion hole 56 to temporarily hold the fastener 7 to the bracket 50 (see FIG. 5).

[0099] After achieving the above state, a pair of corresponding support plates 52, 52 of the bracket 50 are placed on the outside of a pair of first side walls 23, 23 of the base member 20, and the pair of claw portions 55, 55 of the bracket 50 are roughly aligned with the pair of insertion holes 28, 28 of the base member 20, and the bracket 50 is pushed into the base member 20 in the direction indicated by arrow G in Figure 5.

[0100] Then, the pair of claw portions 55, 55 of the bracket 50 are inserted into the pair of insertion holes 28, 28 of the base member 20, and the tip portions 52b, 52b of the pair of support plates 52, 52 of the bracket 50 abut against the inner periphery of the first protrusion 48a and the second protrusion 48b of the pair of positioning portions 48, 48 of the base member 20, thereby restricting further pushing of the bracket 50 into the base member 20 (see Figure 6).

[0101] As a result, the first shaft insertion hole 43 and one of the second shaft insertion holes 53 are positioned concentrically, and the first shaft insertion hole 44 and the other of the second shaft insertion holes 53 are positioned concentrically. In addition, the pair of claw portions 55, 55 of the bracket 50 are fully inserted into the pair of insertion holes 28, 28 of the base member 20, and the fixing plate 51 and the bottom wall 21 engage with each other.

[0102] Furthermore, a fixing plate 51 of the bracket 50 is arranged on the outside of the bottom wall 21 of the base member 20, and a corresponding pair of support plates 52, 52 of the bracket 50 are arranged on the outside of the first shaft insertion holes 43, 43 of a pair of first side walls 23, 23 of the base member 20.

[0103] Furthermore, tip portion 54b of rotation restricting piece 54 of bracket 50 fits into rotation restricting recess 30 of base member 20, restricting rotation of bracket 50 relative to base member 20 (see FIG. 4). Positioning pin 31 of base member 20 fits into notch 57 of bracket 50, positioning and fixing bracket 50 relative to base member 20 (see FIG. 4).

[0104] With the bracket 50 temporarily attached to the base member 20 as described above, the shaft 70 is then inserted into each of the shaft insertion holes 43, 44, 53 along the shaft insertion direction F as shown in FIG. 7 (see FIG. 7).

[0105] That is, the shaft portion 71 of the shaft 70 is inserted, from its tip end 75 side, sequentially through one of the second shaft insertion holes 53 of the bracket 50, the first shaft insertion hole 43 of the base member 20, the first shaft insertion hole 44 of the base member 20, and the other second shaft insertion hole 53 of the bracket 50.

[0106] Then, the shaft 70 is inserted through each shaft insertion hole 43, 44, 53 until the head 73 of the shaft 70 engages with the outer peripheral edge of the second shaft insertion hole 53 of one of the support plates 52 of the bracket 50 and the tip 75 of the shaft portion 71 of the shaft 70 is inserted through the outer opening of the other second shaft insertion hole 53 of the bracket 50.

[0107] Then, the tip portion 75 of the shaft portion 71 crushes and deforms the multiple ribs 46 provided on the inner circumference of the first shaft insertion hole 44, so that the tip portion 75 is pressed into the inside of the first shaft insertion hole 44, and the enlarged diameter portion 77 provided at the base end portion 74 of the shaft portion 71 is pressed into the inside of the first shaft insertion hole 43.

[0108] Thereafter, a retaining ring 9 is attached to the attachment groove 75a of the tip portion 75 of the shaft 70, thereby fixing the shaft 70 to each of the shaft insertion holes 43, 44, 53 so as not to come off (see FIG. 8). As a result, the bracket 50 can be properly attached to the base member 20 so as not to come off.

[0109] Furthermore, by fitting the pair of bearing portions 63, 63 of the lid 60 to the pair of shaft portions 35, 35 of the base member 20, the lid 60 can be attached to the base member 20 so as to be rotatable therewith.

[0110] As described above, the base member 20, the bracket 50, the lid 60, the shaft 70, and the like are assembled to form the load hanging device 10.

[0111] Thereafter, as shown in FIG. 10, the tip portion 54b of the rotation limiting piece 54 of the bracket 50 is inserted into the first insertion hole 3 of the fixed surface 1, the positioning pin 31 of the base member 20 is inserted into the second insertion hole 4, and the shaft portion 7b of the fixing device 7 held by the bracket 50 is inserted into the fixed hole 2 and tightened to fix it, thereby fixing the load hanging device 10 to the fixed surface 1 via the metal bracket 50.

[0112] In this load hanging device 10, as shown in FIG. 7, the first shaft insertion holes 43, 44 have an inner dimension (inner diameter D1) smaller than the inner dimension (inner diameter D2) of the corresponding second shaft insertion holes 53, 53 (D2>D1), and the axial portion 71 of the shaft 70 has an outer dimension (outer diameter D3) larger than the inner dimension (inner diameter D1) of the first shaft insertion holes 43, 44 and smaller than the inner dimension (inner diameter D2) of the second shaft insertion holes 53, 53 (D2>D3>D1).

[0113] Therefore, when the shaft portion 71 of the shaft 70 is inserted into the first shaft insertion hole 43, 44 and the second shaft insertion hole 53, 53, the outer periphery of the shaft portion 71 of the shaft 70 mainly comes into sliding contact with the inner periphery of the first shaft insertion hole 43, 44 and is less likely to come into sliding contact with the inner periphery of the second shaft insertion hole 53, 53. As a result, damage to the outer periphery of the shaft portion 71 of the shaft 70 can be suppressed, thereby improving the appearance.

[0114] In addition, the outer dimensions of the shaft portion 71, which is the part of the shaft 70 that is inserted into and supported by the first shaft insertion holes 43, 44 and the second shaft insertion holes 53, 53, are larger than the inner dimensions of the first shaft insertion holes 43, 44. Therefore, when the shaft portion 71 of the shaft 70 is inserted into the first shaft insertion holes 43, 44 and the second shaft insertion holes 53, 53, the shaft portion 71 is pressed into the inside of the first shaft insertion holes 43, 44 (see Figure 8).

[0115] As a result, the shaft portion 71 of the shaft 70 can be prevented from coming loose in the axial direction and can be restricted from rotating relative to the first shaft insertion holes 43, 44 and the second shaft insertion holes 53, 53, and the shaft portion 71 of the shaft 70 can be supported relative to the first shaft insertion holes 43, 44 while suppressing rattling.

[0116] In addition, in this embodiment, a pair of side walls 23, 23 of the base member 20 are provided with positioning portions 48, 48 that position the first shaft insertion hole 43, 44 and the second shaft insertion hole 53, 53 so that they are concentric, and an engagement portion is provided between the base member 20 and the metal bracket 50, which engages the fixed plate 51 and the bottom wall 21 with each other while the first shaft insertion hole 43, 44 and the second shaft insertion hole 53, 53 are positioned so that they are concentric.

[0117] According to the above embodiment, by inserting a pair of claw portions 55, 55 into a pair of insertion holes 28, 28 and engaging them with each other, the first shaft insertion hole 43, 44 and the second shaft insertion hole 53, 53 can be reliably maintained in a concentrically positioned state (see Figure 9).

[0118] As a result, when the shaft is inserted into the first shaft insertion hole 43, 44 and the second shaft insertion hole 53, 53, the outer periphery of the shaft portion 71 of the shaft 70 can be more reliably prevented from sliding against the inner periphery of the second shaft insertion hole 53, 53, and damage to the outer periphery of the shaft portion 71 can be effectively suppressed.

[0119] In addition, in this embodiment, a plurality of ribs 46 are formed circumferentially on the inner circumference of the first shaft insertion hole on the side where the axial tip 75 of the shaft 70 is inserted. The ribs 46 are crushed and deformed when the tip 75 of the shaft 70 is inserted into the inner circumference of the first shaft insertion hole 44.

[0120] According to the above-described embodiment, a plurality of crushable deformable ribs 46 are formed circumferentially on the side of the first shaft insertion hole where the tip end 75 of the shaft portion 71 of the shaft 70 is inserted, i.e., on the inner circumference of the first shaft insertion hole 44. This keeps the shaft insertion resistance to the shaft insertion hole low, and allows the tip end 75 of the shaft portion 71 of the shaft 70 to be reliably pressed into the inner circumference of the first shaft insertion hole 44 with a relatively light pushing force.

[0121] If, at the initial stage of inserting the shaft into the shaft insertion hole, a rib 46 is formed on the inner circumference of the first shaft insertion hole 43 through which the axial portion 71 of the shaft 70 is inserted, the resistance to shaft insertion into the shaft insertion hole will be large from the initial stage of shaft insertion, making it difficult to insert the shaft 70.

[0122] In contrast to this, in the present embodiment, due to the configuration as described above, the tip 75 of the shaft portion 71 of the shaft 70 can be pressed into the inner circumference of the first shaft insertion hole 44 with a relatively light pushing force, improving the ease of inserting the shaft into the shaft insertion hole.

[0123] In this embodiment, the outer periphery of the expanded diameter portion 77 provided on the outer periphery of the base end 74 of the shank 71 of the shaft 70 is subjected to a predetermined knurling process. Therefore, when the base end 74 of the shank 71 is pressed into the inside of the first shaft insertion hole 43, the inner periphery of the first shaft insertion hole 43 abuts against the outer periphery of the expanded diameter portion 77 so as to bite into it, thereby improving frictional resistance and effectively preventing the shank 71 of the shaft 70 from falling out of the shaft insertion hole.

[0124] Furthermore, in this embodiment, raised portions 41, 41 are provided on the outer surfaces of a pair of first side walls 23, 23 of the base member 20, and the first shaft insertion holes 43, 44 are formed in the portions of the first side walls 23 where the raised portions 41 are provided.

[0125] According to the above aspect, since the first shaft insertion holes 43, 44 are formed as described above, a long path (shaft length) through which the shaft portion 71 of the shaft 70 is inserted in the first shaft insertion holes 43, 44 can be secured, and the press-fitting margin of the shaft portion 71 of the shaft 70 can be increased. As a result, the shaft portion 71 of the shaft 70 can be held more firmly in the first shaft insertion holes 43, 44 without rattling.

[0126] In addition, in this embodiment, when a load is applied to the shaft 70 from the hook 5, the base member 20 is configured to be able to move via the shaft 70 until the shaft 70 abuts against the inner circumference of the second shaft insertion hole 53, 53 (see the dotted line in Figure 12).

[0127] According to the above embodiment, as shown in FIG. 11, when the hook 5 is hooked onto the shaft portion 71 of the shaft 70 and a load from the hook 5 acts on the shaft portion 71 of the shaft 70 (see arrow P in FIG. 11), the base member 20 moves via the shaft 70 until the shaft portion 71 of the shaft 70 abuts against the inner circumference of the second shaft insertion holes 53, 53 (see dashed double-dashed line in FIG. 12). Therefore, the load from the shaft 70 acts mainly on the inner circumference of the second shaft insertion holes 53, 53 on the metal bracket 50 side, rather than the inner circumference of the first shaft insertion holes 43, 44 on the base member 20 side, and the base member 20 can withstand even a large load from the hook 5.

[0128] It should be noted that the present invention is not limited to the above-described embodiment, and various modified embodiments are possible within the scope of the gist of the present invention, and such embodiments are also included in the scope of the present invention.
