However, in order to avoid complication of the drawing in FIG. 11(a), only some of the shape members 51 of the grooves 51a are denoted by reference numerals, and FIG. 11(b) is hatched to indicate a cross section. is omitted. In addition, the three shape members 51, one end of which is arranged at the vertex of the rectangular parallelepiped frame 52, are connected to each other two by two using commercially available corner connectors 54 (see FIG. 12(c)). Illustration of the corner connector 54 is omitted in FIG. 11(a).

The shape member 51 is formed by extrusion of an aluminum alloy or the like, and is a long member having a substantially rectangular cross section. are provided in each. In the groove 51a, as shown in FIG. 11(b), the width s1 of the opening (the _interval between the inner wall surfaces in the direction orthogonal to the longitudinal direction) is narrower _than the width s2 of the inside, and the transport container An additional member 53 for fixing the parts housed inside 50 is fixed to the shaped member 51 using this groove 51a.

12(a) and 12(b) are respectively a front view and a side view of the additional member 53, and FIG. 12(c) is a plan view of the additional member 53 and the shape member 51. The additional member 53 is the shape member. 51 is shown. In addition, in FIG. 12B, the shape member 51 on which the additional member 53 is installed is indicated by a broken line so that the positional relationship between the additional member 53 and the shape member 51 is clarified.

As shown in FIGS. 12(a) and 12(b), the additional member 53 is obtained by cutting the shape member 51 constituting the frame 52 to a desired length, and inserts a groove having the same shape as the groove 51a. 53d, a guide portion 53b composed of a triangular prism forming a substantially right-angled triangle in plan view, and a guide portion 53b installed on one of two side surfaces forming two sides sandwiching the right angle when viewed in plan view. and a locking portion 53c.
The engaging portion 53c includes a wide portion wider than the opening of the groove 51a and narrower than the inside of the groove 51a, and a narrow portion narrower than the opening of the groove 51a and connecting the guide portion 53b and the wide portion. consists of That is, the wide portion has a structure that can be arranged inside the groove 51a, and by arranging the wide portion inside the groove 51a, the engaging portion 53c can slide in the longitudinal direction with respect to the shaped member 51. connected in good condition. One of the side surfaces of the shape member 51 is joined to the other of the two side surfaces of the guide portion 53b.

In the additional member 53, when the wide portion of the engaging portion 53c is arranged inside the groove 51a of the shape member 51, the additional member 53 is not restricted in the movement of the shape member 51 in the longitudinal direction. On the other hand, since the wide portion of the engaging portion 53c is engaged with the inner wall surface of the groove 51a on the opening side, the additional member 53 cannot move in the direction perpendicular to the side surface of the shaped member 51 on which the guide portion 53b is installed. Regulated.
That is, when the wide portion of the engaging portion 53c is arranged inside the groove 51a, the guide portion 53b allows the additional member 53 to move in the longitudinal direction of the shape member 51 while allowing the additional member 53 to move toward the guide portion.

As described above, in the additional member 53, the wide portion of the engaging portion 53c is wider than the opening of the groove 51a, and the engaging portion 53c cannot be inserted into the opening of the groove 51a. Therefore, the additional member 53 can be attached only to the shape member 51 in which at least one end is open.
Therefore, when attaching the additional member 53 to the shape member 51, for example, as shown by arrow H in FIG. The wide portion of the engaging portion 53c is inserted into the groove 51a from the end on the side not connected to the other shaped member 51 so that a part of the locking portion 53c protrudes. After that, the additional member 53 is arranged at a desired position of the shape member 51 by holding the shape member 53a by hand and sliding it in the longitudinal direction of the groove 51a.

In the conveying container 50 having the above structure, since the shape member 53a of the additional member 53 is made of the same material as the shape member 51, there is a problem that the weight of the conveying container 50 as a whole increases as the number of the additional members 53 increases. rice field.
Further, when the shape member 53a is bridged between a pair of parallel shape members 51, 51 for the purpose of partitioning the inside of the transport container 50, a pair of guide portions 53b and locking portions 53c are provided at both ends of the shape member 53a. , and before assembling the frame 52, it is necessary to fit each locking portion 53c into the groove 51a of the shape member 51 having at least one end opened. Therefore, when the frame 52 has already been assembled, the frame 52 must be disassembled in order to open at least one end of the shape member 51 on which the additional member 53 is to be installed. There was a problem that it was bad.

SUMMARY OF THE INVENTION The present invention has been made in response to such conventional circumstances. To provide a rod-like body fixing structure capable of efficiently attaching a body.

In order to achieve the above object, a first invention provides a shaped member having a rectangular cross section and having a groove parallel to the longitudinal direction on at least one side surface, the width of the opening of which is narrower than the width of the interior. A rod-shaped body fixing structure for detachably fixing a rod-shaped body to a shaped member, comprising: a fixing member made of plastic for fixing, the receiving member having a rectangular insertion opening, and a contact member installed so that one surface contacts a side surface provided with a groove; a cylindrical receiving portion that is erected perpendicularly to the other surface of the contact member and into which the rod-shaped body is inserted; the insertion opening is viewed from the side where the contact member receiving portion is provided. The fixture is provided on the abutting member so as to be positioned inside the receiving portion, and the fixture has a flat plate shape and has a size that allows it to be placed inside the receiving portion with the back side abutting on the abutting member. A flat plate-shaped base member provided with a base opening, an engaging claw projecting from the back surface of the base member, and a projection projecting from the back surface of the base member together with the engaging claw so as to be able to be inserted into the insertion opening of the receiver. The engaging claw comprises an engaging portion provided so as to engage with the groove of the shaped member while being inserted into the insertion opening of the receiving tool, and this engaging portion. It has an inclined portion that is tapered from the joining portion to the tip, and a thin portion that is provided between the engaging portion and the proximal end, and the engaging state between the engaging portion and the insertion opening is established. When the front surface of the base member is viewed in a direction perpendicular to the base member, the base opening allows the engaging portion of the engaging claw to pass through the base opening. It is characterized by being formed at a visible position.
In the first invention, "a shape having a rectangular cross section" includes "a shape having a substantially rectangular cross section".

In the rod-shaped body fixing structure described above, the back surface of the base member is arranged in parallel with the abutment member with respect to the receiver installed so that one surface of the abutment member abuts against the side surface of the shaped member. When the fixture is moved in a direction in which the side approaches the other surface of the abutting member, after the engaging claw of the fixture has passed through the insertion opening of the receiving tool, the tip of the fixing tool moves toward the rear side (the side where the engaging portion is not provided). ) and passes through the opening of the groove of the profile. Then, when the engaging portion passes through the opening of the groove of the shape member, the deformation of the engaging claw is restored and the engaging portion engages with the groove of the shape member. As a result, the receiver is fixed to the profile with the abutment member sandwiched between the base member of the fixture and the side of the profile.

Further, as described above, when the receiving member is fixed to the shaped member such that the abutment member is sandwiched between the base member of the fixture and the side surface of the shaped member, the base opening is opened from the front side of the base member. When a tool or the like is inserted into the opening and the tip of the tool is pressed against the thin portion, the engaging claw is elastically deformed so as to bend toward the rear side. At this time, the posture of the base member with respect to the receiving tool is maintained by engaging the convex portion with the insertion opening of the receiving tool.
When the tool is operated to deform the engaging claw until the engaging portion does not engage with the groove of the shape member, the engagement state of the fixture with respect to the shape member is released, so that the fixture is Detachable from the shaped material. Therefore, when the fixing tool is removed from the shaped member and the receiving tool by pulling out the engaging claw from the insertion opening of the receiving tool, the receiving tool can also be separated from the shaped material.

That is, in the first invention, in a state in which the abutment member of the receiving tool installed on the side surface of the shape is sandwiched between the base member of the fixture and the side surface of the shape, By engaging the engaging claws of the fixture with the grooves of the shaped member from any direction, the receiver is fixed to the shaped member. Also, when the receiving tool is fixed to the shaped member, a tool or the like inserted into the base opening from the front side of the base member is used to check the engagement state between the engaging claw of the fixing tool and the groove of the shaped member. It has the effect that the fixture and the receiver can be removed from the shaped member simply by performing a simple operation of deforming the engaging claws in the direction of disengagement.

In a second aspect of the invention, in the first aspect, the abutment member is made of a flat plate material having both ends bent at right angles to the side where the receiving part is not provided, and a pair of bent parts are provided at both ends. The flat plate portion is provided with an insertion hole, and the pair of bent portions are formed so that the distance between them is wider than the width of the side surface of the shape member so that the side surface of the shape member can be sandwiched. .
In the second invention, in addition to the effect of the first invention, when the abutment member is installed on the side surface of the shape so that the shape is sandwiched between the pair of bent portions, the width of the side of the shape is increased by the contact member. It has the effect that the movement of the receiver with respect to the direction is restricted.

In a third invention, in the first invention or the second invention, instead of the rod-shaped body having a circular cross-sectional profile, the receiving member made of a plastic member, and the receiving part having a cylindrical shape, A portion of the side surface of a cylinder into which the rod-shaped body can be inserted is cut out parallel to the longitudinal direction over the entire length, and the insertion hole provided in the contact member is the receiving portion. When the abutting member is viewed from the side on which it is provided, it is positioned inside the arc formed by the receiving portion, and the cross section of the receiving portion forms an arc with a central angle greater than 180 degrees. It is characterized.

In the third invention, in addition to the effects of the first invention or the second invention, the side opening ( When the rod-shaped body is pressed against the part of the side surface of the cylinder which is partially notched, the receiving part is elastically deformed to widen the side opening. When the receiving portion is deformed to such an extent that the side opening can pass through the rod-shaped body, the rod-shaped body is placed inside the receiving portion by pushing the rod-shaped body into the receiving portion through the side opening. be done.
When the rod passes through the side opening of the receiving part, the receiving part recovers its deformation and returns to a shape having an arcuate cross-section with a central angle greater than 180 degrees. As a result, the side surface of the rod-shaped body is covered by the receiving portion in a range exceeding 1/2 of the circumferential direction, and the end portion of the rod-shaped body is held by the receiving portion. .
In the third invention, when the end of the rod-shaped body is held by the receiving part, the rod-shaped body can be removed from the receiving part by pulling the end of the rod-shaped body out of the side opening. have.

According to a fourth invention, in the third invention, a slit having a desired width is provided in the side surface of the receiving portion along the circumferential direction from the end surface of the notched portion. be.
As already mentioned, with the central axis of the arc-shaped receiving part and the longitudinal direction of the rod-like body parallel to each other, the rod-like body is inserted into the side opening of the receiving part (the portion where the side surface of the cylinder is partially cut away). is pressed, the receiving part is elastically deformed so that the side opening widens, but the deformation of the receiving part is restrained by the contacting member at the portion where the receiving part is connected to the contacting member. Therefore, in the vicinity of the contact member, the deformation of the receiving portion is restricted due to the effect of the action of the contact member, which restrains the deformation of the receiving portion.

On the other hand, when a slit is provided along the circumferential direction from the end face of the notched portion of the side surface of the receiving portion, the above-mentioned function of the contact member to restrain the deformation of the receiving portion is alleviated by the slit. Therefore, between the slit and the end portion not connected to the contact member, the above action of the contact member to restrain the deformation is difficult to reach, so the receiving portion is more likely to deform than when there is no slit. state.
Therefore, in the fourth invention, in a state in which the central axis of the arc-shaped receiving portion and the longitudinal direction of the rod-shaped body are parallel, the side opening of the receiving portion (a portion where a part of the side surface of the cylinder is notched) is provided. The function of the third invention, in which the receiving portion is elastically deformed so as to widen the side opening when the rod-like body is pressed, is further exhibited between the end portion not connected to the abutting member and the slit. be done.

It consists of an abutment member 8 that is
Both ends of the contact member 8 are bent at right angles to the side where the receiving portion 9a is not provided, and the interval between the bent portion 8a and the flat plate portion 8b which are parallel to each other is wider than the width of the side surface of the shape member 51. The shape is such that the side surface of the shape member 51 can be sandwiched between the bent portion 8a and the flat plate portion 8b.

Further, when the contact member 8 is viewed from the side where the receiving portion 9a is provided, the pair of flat plate portions 8b, 8b that contact the two side surfaces of the shape member 51 are formed by the receiving portion 9a. Rectangular insertion openings 8c, 8c are provided so as to be positioned inside the arc.
The insertion opening 8c of the contact member 8 and the insertion opening 6c of the contact member 6 have the same size. Further, the inner diameters of the receiving portions 9a and 7a (the curvature radii of the inner surfaces of the receiving portions 7a and 9a which are arc-shaped) are the same, but the inner diameter of the receiving portion 9a is the same as that of the base member 10 (see FIG. 5A). larger than the outer diameter of Furthermore, the center of the insertion opening 8c (the intersection of two diagonal lines of the rectangle) is arranged on the central axis of the receiving portion 9a (the central axis of the short cylinder whose side surface is partly cut).

A pair of slits 9b, 9b with a desired width are provided in the side surface of the receiving portion 9a in the vicinity of the contact member 8 along the circumferential direction from the end faces 9d, 9d of the notched portion. Further, the receiving portion 9a forms a right-angled triangle in plan view, and a pair of reinforcing plates 9c in which two surfaces forming two sides sandwiching the right angle are respectively joined to the side surface of the receiving portion 9a and the flat plate portion 8b of the contact member 8. , 9c reinforce the connecting portion between the contact member 8 and the receiving portion 9a so as to prevent the receiving portion 9a from being easily separated from the contact member 8 due to a crack.

In the second pipe receiver 4 having such a structure, the shape member 51 is sandwiched from both sides by the bent portion 8a and the flat plate portion 8b which are parallel to each other, and the two flat plate portions 8b and 8b are attached to the two portions of the shape member 51. It is installed on the shape member 51 so as to abut on the side surfaces thereof (see FIG. 1). In this case, since the movement of the receiver 9a in the direction orthogonal to the bent portion 8a and the flat plate portion 8b which are parallel to each other is restricted by the abutting member 8, when the fixing member 5 is attached to the shape member 51 or when the shape member 51 There is no risk that the second pipe receiver 4 will move in a direction perpendicular to the bent portion 8a and the flat plate portion 8b that are parallel to each other when removed from the tube. Therefore, the work of fixing the second pipe receiver 4 using the fixture 5 and the work of removing the fixture 5 from the second pipe receiver 4 can be easily performed.

The round pipe 2 is moved as indicated by the arrow X in FIG. When the round pipe 2 is pressed against the side opening 7e (9e) of the receiving portion 7a (9a) (the part where the side surface of the cylinder is partially notched), the receiving portion 7a (9a) is as shown in FIG. 4(b). , and the side opening 7e (9e) widens. Then, when the receiving portion 7a (9a) is deformed to the extent that the side opening 7e (9e) can pass through the round pipe 2, the inside of the receiving portion 7a (9a) from the side opening 7e (9e) The round pipe 2 can be placed inside the receiving portion 7a (9a) by pushing the round pipe 2 inward.

When the round pipe 2 passes through the side opening 7e (9e) of the receiving portion 7a (9a), the receiving portion 7a (9a) recovers its original shape. As shown in FIG. 4A, the cross section of the receiving portion 7a (9a) forms an arc with a central angle greater than 180 degrees. Therefore, as shown in FIG. 4(c), the side surface of the round pipe 2 disposed inside the receiving portion 7a (9a) has a range exceeding 1/2 of the side surface of the receiving portion 7a (9a) in the circumferential direction. ). Thus, the end of the round pipe 2 is held by the receiving portion 7a (9a).

On the other hand, in the state shown in FIG. 4(c), the central axis 7f of the receiving portion 7a (see FIG. 7(a)) and the central axis of the round pipe 2 are kept parallel to each other. When a force is applied in the direction opposite to the arrow X shown in 4(a), the receiving portion 7a (9a) is elastically deformed as shown in FIG. 4(b) to widen the side opening 7e (9e). When the receiving portion 7a (9a) is deformed to the extent that the side opening 7e (9e) can pass through the round pipe 2, the round pipe 2 is pulled out from the side opening 7e (9e). The round pipe 2 can be taken out of the receiving portion 7a (9a).
The easiness of deformation of the receiving portion 7a (9a) is determined by "the material and thickness of the receiving portion 7a (9a)", "the central angle of the arc formed by the cross section of the receiving portion 7a (9a)", and It can be adjusted by changing the ratio of the outer diameter of the round pipe 2 to the inner diameter of the receiving portion 7a (9a).

As described above, with the central axis of the receiving portion 7a (9a) and the central axis of the round pipe 2 parallel to each other, when the round pipe 2 is pressed against the side opening 7e (9e) of the receiving portion, the receiving portion 7a (9a) ) is elastically deformed so that the side opening 7e (9e) expands, but at the portion where the receiving portion 7a (9a) is connected to the contact member 6 (8), the contact member 6 (8) causes the receiving portion 7a to expand. The deformation of (9a) is constrained. Therefore, the deformation of the receiving portion 7a (9a) is limited by the action of the contacting member 6 (8) that restrains the deformation of the receiving portion 7a (9a) in the vicinity of the contacting member 6 (8).

Since the action of the contact member 6 (8) that restrains the deformation of the receiving portion 7a (9a) is relieved by the slit 7b (9b), the end of the contact member 6 (8) not connected to the contact member 6 (8) is reduced. The effect of the abutting member 6 (8), which restrains deformation, does not easily reach between the portion and the slit 7b (9b). As a result, the receiving portion 7a (9a) is more easily deformed than when the slit 7b (9b) is absent.
That is, the slit 7b (9b) relaxes the action of the contact member 6 (8) that restrains deformation when the round pipe 2 is pressed against the side opening 7e (9e) of the receiving portion 7a (9a). As a result, the side opening 7e (9e) is easily elastically deformed to widen the receiving portion 7a (9a).

5(a) and 5(b) are a perspective view and a plan view, respectively, showing an example of the appearance of the fixture 5, and FIGS. It is a direction arrow view and a D direction arrow view. 6(a) and 6(b) are cross-sectional views taken along line EE in FIG. 5(b).
As shown in FIGS. 5(a) to 5(d), the fixture 5 includes a flat plate-like base member 10 having a circular shape in plan view, and four engaging members protruding from the rear surface 10b of the base member 10. It consists of a claw 11 and a pair of convex portions 12 , 12 .

The four engaging claws 11 have engaging portions 11a (see FIGS. 6(a) and 6(b)) on the outside of the rectangle corresponding to the two long sides of the rectangle when viewed from above. The pair of convex portions 12, 12 are arranged in positions corresponding to the two short sides of the above-mentioned rectangle, respectively, with the four engaging claws 11 interposed therebetween.
The center of the rectangle (the intersection of the two diagonal lines) coincides with the center of the circle formed by the contour lines when the base member 10 is viewed from above. Further, the base member 10 is provided with a base opening 10a. The base opening 10a is formed at a position where the engaging portion 11a of the engaging claw 11 can be visually recognized through the base opening 10a when the front surface 10c is viewed in a direction perpendicular to the base member 10. .

_The back surfaces 12a of the pair of convex portions 12, 12 are parallel to each other. It is narrower than the horizontal width L of the insertion opening 8c (see FIG. 7(c)). 5A, the convex portion 12 has a stepped structure having a wide portion 12b and a narrow portion 12c. The width w ₁ (see FIG. 5(d)) of the wide portion 12b near the back surface 10b of the contact member 6 and the vertical width w (see FIG. 7(c) of the insertion port 6c of the contact member 6 and the insertion port 8c of the contact member 8 ) and wider than the width s ₁ of the opening of the groove 51a of the shape member 51 (see FIG. 11(b)). The width w ₂ (see FIG. 5(d)) of the narrow portion 12c provided between the wide portion 12b and the distal end portion 12d corresponds to the width s ₁ (see FIG. 11(b) ) narrower than ).

A pair of engaging claws 11, 11 arranged back to back are attached to the engaging portion 11a (see FIG. 6(a)) provided near the tip portion 12d (see FIG. 5(d)) of the convex portion 12. The maximum width w ₃ between (see FIG. 5(d)) is the vertical width w (see FIG. 7(c)) of the insertion opening 6c of the contact member 6 and the insertion opening 8c of the contact member 8 and the shape member 51. Although it is narrower than the width s ₂ inside the groove 51a (see FIG. 11B), it is wider than the width s ₁ of the opening of the groove 51a of the shape member 51 (see FIG. 11B). The maximum width between the thin portions 11c (see FIG. 6(a)) of the pair of engaging claws 11, 11 arranged back to back is the width w ₂ of the narrow portion 12c (see FIG. 5(d)). (see FIG. 6(a)).

The engaging claw 11 is inserted into the insertion opening 6c of the first pipe receiver 3 or the insertion opening 8c of the second pipe receiver 4 as will be described later with reference to FIG. 8(a). An engaging portion 11a is provided so as to be engageable with the groove 51a of 51 . As shown in FIG. 6(a), an inclined portion 11b is provided so as to taper from the engaging portion 11a to the distal end 11d. The thin portion 11c described above is provided therebetween.

Further, the engaging claw 11 can swing by elastic deformation within a predetermined angular range about the proximal end 11e in the direction in which the angle formed by the back surface 11f and the front surface 10c of the base member 10 becomes smaller. That is, when the engaging portion 11a is engaged with the insertion opening 6c of the first pipe receiving member 3 or the insertion opening 8c of the second pipe receiving member 4, the engaging claw 11 is positioned as shown in FIG. The structure is such that it can be elastically deformed toward the rear surface 11f until it reaches the state indicated by the dashed line in FIG.

Therefore, in the fixture 5, as shown in FIG. 6B, a tool 13 having a flat tip, such as a flat-blade screwdriver, is inserted into the base opening 10a from the front surface 10c side of the base member 10. After that, by pushing the thin portion 11c with the tip of the tool 13 and bending the engaging claw 11, the engaging claw 11 is brought into the state shown by the broken line in FIG. 6(a) as described above. can be done.
Here, the inner wall surface of the base opening 10a is tapered so that the opening area on the front surface 10c side is larger than the opening area on the back surface 10b side. As a result, the movable range of the tool 13 inserted from the base opening 10a to deform the engaging claw 11 is widened. That is, according to the fixture 5 having such a structure, it is possible to easily perform the work of bending the engaging claw 11 with the tip of the tool 13 .

FIG. 7(a) is a side view of the first pipe receiver 3 and fixture 5, and FIGS. 7(b) and 7(c) respectively show the first pipe receiver 3 to which the fixture 5 is attached. is viewed from the receiving portion 7 side and the contact member 6 side. 8(a) and 8(b) are cross-sectional views taken along line GG in FIG. 7(b).
9(a) and 9(b) show the state in which the second pipe receiver 4 is attached to the shaped member 51 using the fixture 5, and FIG. It corresponds to the cross-sectional view of (a) and FIG. 8 (b). 10(a) and 10(b) show the state in which the first pipe receiver 3 and the second pipe receiver 4 are attached to the shaped member 51 using the fixture 5, respectively.
As shown in FIG. 7(a), with the central axis 10d of the base member 10 aligned with the central axis 7f of the receiving portion 7a, the fixture 5 is moved in the direction indicated by the arrow F with respect to the first pipe receiver 3. Since the outer diameter of the base member 10 is smaller than the inner diameter of the receiving portion 7a, the fixing member 5 is moved inside the receiving portion 7a of the first pipe receiving member 3 as shown in FIG. 7(b). placed.

As described above, when the back surface 10b of the base member 10 of the fixture 5 is viewed in plan, the four engaging claws 11 and the pair of convex portions 12, 12 are arranged so as to form each side of a rectangle. However, the center of this rectangle (the intersection of two diagonal lines) is arranged on a straight line that passes through the center of the circle formed by the outline of the base member 10 when viewed from above and is perpendicular to the back surface 10b. , the center of the insertion opening 6c of the contact member 6 (the intersection of the two diagonal lines of the rectangle) is arranged on the central axis 7f of the receiving portion 7a (see FIG. 7A).

5(c) and 5(d), the distance L ₁ (see FIG. 5(c)) between the back surfaces 12a of the pair of convex portions 12, 12 is the contact member 6 width L (see FIG. 7(c)) of the insertion opening 6c of the contact member 6, and the width w ₁ (see FIG. 5(d)) of the wide portion 12b of the convex portion 12 is equal to the insertion opening 6c of the contact member 6. is narrower than the vertical width w (see FIG. 7(c)).
Therefore, in the fixing device 5, when the base member 10 is arranged inside the receiving portion 7a so as to be parallel to the flat plate portion 6b of the abutment member 6 of the first pipe receiving device 3, FIG. As shown in (c), four engaging claws 11 and a pair of convex portions 12, 12 can be inserted through the insertion opening 6c of the contact member 6. As shown in FIG.

As already described, the width w ₁ (see FIG. 5(d)) of the wide portion 12b of the convex portion 12 is wider than the width s ₁ (see FIG. 11(b)) of the opening of the groove 51a of the shape member 51. , the width w ₂ of the narrow portion 12c (see FIG. 5(d)) is narrower than the width s ₁ of the opening of the groove 51a of the profile 51 (see FIG. 11(b)). On the other hand, the pair of engaging claws 11, 11 arranged back to back are engaged with the engaging portion 11a (see FIG. 6(a)) provided near the tip portion 12d (see FIG. 5(d)) of the convex portion 12. ) is the vertical width w of the insertion opening 6c of the contact member ₆ (see FIG. 7C) and the internal width s of the groove 51a of the shape member 51 (see FIG. 5D). ₂ (see FIG. 11(b)) and wider than the width s ₁ of the opening of the groove 51a of the profile 51 (see FIG. 11(b)). The maximum width between the thin portions 11c (see FIG. 6(a)) of the pair of engaging claws 11, 11 is narrower than the width w ₂ (see FIG. 5(d)) of the narrow portion 12c (see FIG. 5(d)). 6(a)).

Therefore, when the four engaging claws 11 and the pair of convex portions 12, 12 are inserted into the insertion opening 6c of the contact member 6, the tip 11d of the engaging claw 11 is bent toward the rear surface 11f, and is After being deformed to the state indicated by the dashed line in (a), when the engaging portion 11a passes through the opening of the groove 51a of the shape member 51, the deformed state of the tip 11d is recovered and the original shape is restored.

Therefore, as shown in FIG. 8(a), the fixture 5 has the engaging portion 11a (see FIG. 6(a)) in a state where the engaging claw 11 is inserted into the insertion opening 6c of the first pipe receiving member 3. engages with the groove 51 a of the shape member 51 , the engaging claw 11 cannot be separated from the shape member 51 . In this manner, the first pipe receiver 3 is fixed to the shape member 51 with the contact member 6 sandwiched between the base member 10 of the fixture 5 and the side surface of the shape member 51 .
In the state shown in FIG. 8(a), as shown in FIG. 8(b), the tip of the tool 13 is inserted into the base opening 10a (see FIG. 6(a)) from the front surface 10c side of the base member 10. By pressing the thin portion 11c (see FIG. 6A), the engaging claw 11 is pushed until the engaging portion 11a (see FIG. 6A) does not engage with the groove 51a of the shaped member 51. When bent, the engaging state between the engaging portion 11 a (see FIG. 6A ) and the groove 51 a of the shape member 51 is released, and the engaging claw 11 can be separated from the shape member 51 . Therefore, when the fixture 5 is removed from the shaped member 51 and the first pipe receiver 3 by pulling the engaging claw 11 out of the insertion opening 6c of the first pipe receiver 3, the first pipe receiver 3 is also removed. It will be in a detachable state from the shape member 51 .

At this time, as shown in FIG. 8(a), the wide portion 12b (see FIG. 5(d)) of the pair of convex portions 12, 12 is engaged with the insertion opening 6c of the first pipe receiver 3. prevents the base member 10 from swinging with respect to the shape member 51, and the narrow portion 12c (see FIG. 5(d)) is engaged with the opening of the groove 51a of the shape member 51, so that the base member 10 and the contact member 6 , the posture of the base member 10 with respect to the contact member 6 of the first pipe receiver 3 is maintained. Therefore, in the fixture 5, when the tool 13 inserted into the base opening 10a (see FIG. 6A) of the base member 10 is operated, the base member 10 does not move without permission. can be used to easily bend the tip 11d of the engaging claw 11 (see FIG. 6A).

If the fixture 5 is not provided with the convex portion 12, it is not easy to deform the engaging claw 11 with the tool 13, but the engaging portion 11a (Fig. ))), the engagement state of the engaging portion 11a (see FIG. 6A) of the engaging claw 11 with the groove 51a of the shape member 51 can be released. However, in this case, the fixture 5 cannot be used repeatedly.
In contrast, according to the rod-shaped body fixing structure according to the present invention, the fixture 5 can be removed from the shaped member 51 without breaking the engaging portion 11a (see FIG. 6A). can be used repeatedly.

Next, a procedure for fixing the second pipe receiver 4 to the shaped member 51 using the fixture 5 will be described with reference to FIGS. 9(a) and 9(b).
7(a) and 7(b), the central axis of the receiving portion 9a (the above-mentioned short cylinder whose side is 7A) of the base member 10 is aligned with the center axis) of the base member 10, the fixture 5 is moved toward the second pipe receiver 4, and the base member 10 Since the outer diameter is smaller than the inner diameter of the receiving portion 9a, the fixing member 5 is arranged inside the receiving portion 9a of the second pipe receiving member 4. As shown in FIG.

As already described, when the back surface 10b (see FIG. 6A) of the base member 10 of the fixture 5 is viewed in plan, the four engaging claws 11 and the pair of convex portions 12, 12 form each side. The center of the rectangle (the intersection of two diagonal lines) is on a straight line perpendicular to the back surface 10b (see FIG. 6A) passing through the center of the circle formed by the outline when the base member 10 is viewed from above. , and the center of the insertion opening 8c of the contact member 8 (the intersection of two diagonal lines of the rectangle) is arranged on the center axis of the receiving portion 9a.

5(c) and 5(d), the distance L ₁ (see FIG. 5(c)) between the back surfaces 12a of the pair of convex portions 12, 12 is the contact member 8 width w ₁ (See FIG. 5(d)) is narrower than the vertical width of the insertion opening 8c of the contact member 8 (equal to the vertical width w of the insertion opening 6c of the contact member 6 in the first pipe receiver 3).
Therefore, in the fixing device 5, when the base member 10 is arranged inside the receiving portion 8a so as to be parallel to the flat plate portion 8b of the contacting member 8 of the second pipe receiving device 4, the contact Four engaging claws 11 and a pair of convex portions 12, 12 can be inserted through the insertion opening 8c of the member 8. As shown in FIG.

The pair of engaging claws 11, 11 arranged back to back are engaged with the engaging portion 11a (see FIG. 6(a)) provided near the distal end portion 12d (see FIG. 5(d)) of the convex portion 12. ) is the vertical width of the insertion opening 8c of the contact member ₈ (the vertical width of the insertion opening 6c of the contact member 6 in the first pipe receiver 3) w.) narrower.
Therefore, when the four engaging claws 11 and the pair of convex portions 12, 12 are inserted into the insertion opening 8c of the contact member 8, the tip 11d of the engaging claw 11 is bent toward the rear surface 11f, and is After being deformed to the state indicated by the dashed line in (a), when the engaging portion 11a passes through the opening of the groove 51a of the shape member 51, the deformed state of the tip 11d is recovered and the original shape is restored.

Therefore, as shown in FIG. 9(a), the fixture 5 has the engaging portion 11a (see FIG. 6(a)) with the engaging claw 11 inserted into the insertion opening 8c of the second pipe receiving member 4. As shown in FIG. engages with the groove 51 a of the shape member 51 , the engaging claw 11 cannot be separated from the shape member 51 . In this manner, the second pipe receiver 4 is fixed to the shape member 51 with the contact member 8 sandwiched between the base member 10 of the fixture 5 and the side surface of the shape member 51 .
In the state shown in FIG. 9(a), as shown in FIG. 9(b), the tip of the tool 13 inserted into the base opening 10a (see FIG. 6(a)) from the front surface 10c side of the base member 10 By pressing the thin portion 11c (see FIG. 6A), the engaging claw 11 is pushed until the engaging portion 11a (see FIG. 6A) does not engage with the groove 51a of the shaped member 51. When bent, the engaging state between the engaging portion 11 a (see FIG. 6A ) and the groove 51 a of the shape member 51 is released, and the engaging claw 11 can be separated from the shape member 51 . Therefore, when the fixture 5 is removed from the shaped member 51 and the second pipe receiver 4 by pulling the engaging claw 11 out of the insertion opening 8c of the second pipe receiver 4, the second pipe receiver 4 is also removed. It will be in a detachable state from the shape member 51 .

At this time, as shown in FIG. 9(a), the wide portion 12b (see FIG. 5(d)) of the pair of convex portions 12, 12 is engaged with the insertion opening 8c of the second pipe receiver 4. prevents the base member 10 from swinging with respect to the shape member 51, and the narrow portion 12c (see FIG. 5(d)) engages with the opening of the groove 51a of the shape member 51, so that the base member 10 and the contact member 8 In order to prevent rocking motion with respect to the shape member 51, the posture of the base member 10 with respect to the contact member 8 of the second pipe receiver 4 is maintained. Therefore, in the fixture 5, when the tool 13 inserted into the base opening 10a (see FIG. 6(a)) of the base member 10 is operated, the base member 10 does not move without permission. Using this, the work of bending the tip 11d (see FIG. 6A) of the engaging claw 11 can be easily performed.

As described above, in the rod-shaped body fixing structure of the present invention constituted by the first pipe receiver 3 and the fixture 5 or the second pipe receiver 4 and the fixture 5, the side surface of the shape member 51 has With the contact member 6 of the installed first pipe receiver 3 or the contact member 8 of the second pipe receiver 4 sandwiched between the base member 10 of the fixture 5 and the side surface of the shaped member 51, By engaging the engaging claws 11 of the fixture 5 with the grooves 51a of the shape member 51 from a direction perpendicular to the side surface of the shape member 51, the first pipe receiver 3 or the second pipe receiver 4 is attached. It is fixed to the profile 51 .

Further, when the first pipe receiver 3 or the second pipe receiver 4 is fixed to the shape member 51, the tool 13 inserted into the base opening 10a from the front surface 10c side of the base member 10 is used to A simple operation of deforming the engaging claw 11 in the direction in which the engaging state between the engaging claw 11 of the fixture 5 and the groove 51a of the shaped member 51 is canceled allows the first pipe receiving member 3 to be opened. and the fixture 5 or the second pipe receiver 4 and the fixture 5 can be removed from the profile 51 .
That is, according to the rod-shaped body fixing structure of the present invention, the first pipe receiver 3 and the fixture 5, or the second pipe receiver 4 and the fixture 5 are arranged from the direction perpendicular to the side surface of the shaped member 51. or remove the first pipe receiver 3 and fixture 5 or the second pipe receiver 4 and fixture 5 attached to the profile 51 in a direction perpendicular to the side surface of the profile 51 It is possible.

12(a) to 12(c), when attaching the additional member 53 to the shape member 51, the engaging portion 53c is inserted from the end portion of the shape member 51 into the groove 51a. The wide part must be inserted. Further, when the additional member 53 attached to the shape member 51 is removed from the shape member 51, the additional member 53 is slid in the longitudinal direction of the shape member 51 so that the locking portion disposed inside the groove 51a is removed. It is necessary to take out the wide part of 53c from the end of the profile 51 . Therefore, the additional member 53 cannot be attached to or removed from the shape member 51 to which other shape members 51 are connected at both ends.

On the other hand, in the rod-shaped body fixing structure of the present invention, the first pipe receiver 3, the second pipe receiver 4, and the fixture 5 are attached to and removed from the shape member 51 in a direction perpendicular to the side surface. It is possible. Therefore, as shown in Figs. 10(a) and 10(b) , the first pipe receiver 3 and the second pipe support 51 are connected to both ends of the shape member 51 in a state where other shape members 51 are connected. The pipe receiver 4 and fixture 5 can be attached or removed.

Further, in the rod-shaped body fixing structure of the present invention, the round pipe 2 is pushed into the receiving portion 7a or the receiving portion 9a through the side opening 7e of the receiving portion 7a or the side opening 9e of the receiving portion 9a. 2 can be placed. Therefore, as shown in FIGS. 10( a ) and 10 ( b ), the first pipe receiver 3 or the second pipe receiver 4 are parallel to each other and their ends are separated by separate shape members 51 . Even if it is attached to the two shape members 51 that are connected and cannot be spaced apart from each other and fixed by the fixing device 5, the receiving portion 7a of the first pipe receiving device 3 or the second pipe receiving device By arranging the end of the round pipe 2 inside the receiving portion 9 a of the tool 4 , the round pipe 2 can be installed so as to connect the two shaped members 51 .

The round pipe 2 is placed in parallel with the central axis of the receiving portion 7a of the first pipe receiving member 3 or the receiving portion 9a of the second pipe receiving member 4 installed on the two shaped members 51. In order to extend the distance between two profiles 51 when they are inserted, another profile 51 connecting their ends must be removed.
Also, the round pipe 2 installed so as to connect the two shaped members 51 is moved from the receiving portion 7a of the first pipe receiving member 3 or the receiving portion 9a of the second pipe receiving member 4 to their central axes. In order to widen the space between the two shape members 51 even when they are pulled out parallel to , it is necessary to remove another shape member 51 connecting the ends thereof.

On the other hand, in the rod-shaped body fixing structure of the present invention, the round pipe is pushed into the inside of the receiving portion 7a of the first pipe receiving member 3 or the receiving portion 9a of the second pipe receiving member 4 from the side thereof. 2 can be inserted. Therefore, when the round pipe 2 is attached to or removed from the two shape members 51, there is no need to widen the space between the two shape members 51. As shown in FIG.
That is, according to the rod-shaped body fixing structure of the present invention, the two shape members 51 which are parallel to each other and whose ends are connected by another shape member 51 are connected so as to connect the round pipe 2 . or when removing the round pipe 2 from the two shaped members 51, there is no need to remove another shaped member 51 that connects the ends of the two shaped members 51. The work of attaching and detaching the pipe 2 can be performed efficiently.

Since the receiving portion 7a is provided with the slit 7b, and the receiving portion 9a is provided with the slit 9b, the round pipe 2 is inserted into the side opening 7e or the side opening of the receiving portion 7a or the receiving portion 9a. When pushed in from 9e or pulled out from side opening 7e or side opening 9e, receiving portion 7a and receiving portion 9a are more easily deformed than when slit 7b and slit 9b are not provided. As a result, the effect of being able to efficiently perform the work of attaching and detaching the round pipe 2 is further exhibited.

Further, in the transporting container 1 of the present invention, the frame 52 is composed of the metal shape member 51. Compared with the case where the plastic shape member 51 is used, the assembly accuracy of the frame 52 is high. It can be used when delivering a heavy object with high rigidity to a customer. Furthermore, since the rod-shaped body fixing structure of the present invention can be installed in the groove 51a of the shape member 51, it is possible to efficiently attach rod-shaped bodies used for fixing stored articles and partitioning. Further, since the rods are round pipes 2 made of plastic, even if the number of rods is increased, the increase in weight is small, so that the weight of the entire container can be reduced.

The rod-shaped body fixing structure of the present invention is not limited to the structures shown in the above embodiments. For example, the contact member 6 of the first pipe receiver 3 may have a structure consisting only of the flat plate portion 6b without providing the pair of bent portions 6a, 6a at both ends. Also, instead of the round pipe 2, a rod-like body having a solid structure can be used. However, in this case as well, in order to reduce the weight of the container as a whole, it is desirable that the bar is made of plastic.

Further, the receiving portion 7a of the first pipe receiving member 3 and the receiving portion 9a of the second pipe receiving member 4 have a shape in which a part of the side surface of the cylinder is notched over the entire length in parallel with the longitudinal direction. Alternatively, it may be a cylindrical member with a circular or polygonal cross-sectional profile.
In this case, the round pipe 2 cannot be inserted into the receiving portion 7a of the first pipe receiving member 3 or the receiving portion 9a of the second pipe receiving member 4 by pushing from the side surface thereof. The round pipe 2 must be inserted into the receiving portion 7a of the pipe receiving device 3 or the receiving portion 9a of the second pipe receiving device 4 in parallel with their central axes. Therefore, when attaching the round pipe 2 so as to connect the two shape members 51 which are parallel to each other and whose ends are connected by another shape member 51 , or from the two shape members 51 . When removing the round pipe 2, it is necessary to remove another shape member 51 connecting the ends of the two shape members 51 to each other.

In the above embodiment, the four side surfaces of the shape member 51 are provided with the grooves 51a. The rod-shaped body fixing structure of the present invention can be attached to the shape member 51 if the groove 51a is provided on the side surface. Furthermore, the shaped member 51 may be made of a metal other than an aluminum alloy.

The transport container of the present invention can be used to transport not only heavy objects with high rigidity such as automobile parts, but also various parts. Moreover, the rod-shaped body fixing structure of the present invention is applicable not only to a transport container but also to a case where a rod-shaped body is detachably fixed to a desired object.
