[0004] The above-mentioned suspension bolt support has the following problems. That is, when fastening the suspension bolt at a desired height by screwing or the like, it is necessary to perform the work of positioning the suspension bolt support with one hand and tightening the fastening bolt with the other hand. This requires the worker to use both hands. However, it becomes necessary to adjust the height position of the suspension bolt support depending on the positional relationship with other materials, that is, the handling situation of the electrical equipment. In such a case, it is necessary to adjust the suspension bolt support to an appropriate height position on an unstable stepladder or ladder while performing the screw tightening work, which is dangerous and troublesome.

[0010] (First embodiment) 1 and 2 respectively show the use of a suspension bolt support 10 according to a first embodiment of the present invention. As shown in Figs. 1 and 2, the suspension bolt support 10 is fixed to a suspension bolt B when in use. For example, as shown in Fig. 1, a pyrac clip Q is attached to the suspension bolt support 10 fixed to the suspension bolt B, and an electric wire pipe P (electrical installation material) is passed through the pyrac clip Q and fixed with a bolt nut. Also, as shown in Fig. 2, a cable support bracket S as a steel rod curved in a semicircular shape is attached via a screw to the suspension bolt support 10 fixed to the suspension bolt B, and a cable C is laid in the cable support bracket S and fixed with a cable tie.

[0011] As shown in Figs. 3 to 8, the suspension bolt support 10 accommodates an auxiliary metal fitting (clamping portion) 60 configured as a groove frame having a substantially U-shaped cross section inside a main metal fitting (main body) 20 configured as a substantially rectangular cylinder with a bottom, and the main body 20 and the clamping portion 60 are fastened to each other at their bottom plates by a fastening bolt 90. The tip edges of the upper and lower side plates of the main body 20 are notched in a concave shape. The upper and lower groove plates of the clamping portion 60 are configured in a hook shape. A suspension bolt B is introduced between the concave edges of the upper and lower side plates of the main body 20 and the hook-shaped groove plate of the clamping portion 60. The main body 20 and the clamping portion 60 are biased by an elastic member in a direction to clamp the suspension bolt B. The suspension bolt support 10 can be temporarily fixed to the suspension bolt B in a temporary fastening state in which the fastening bolt 90 is not completely fastened by the elastic member. Typically, these parts are made of metal, but all or some of the parts may be made of hard resin. In detail, the suspension bolt support 10 is configured as follows.

[0012] The main body 20 is configured as a substantially rectangular cylinder with a bottom. Specifically, the main body 20 includes a rectangular plate-shaped main body base 30, a pair of plate-shaped bracket attachment parts 40, 50 provided on both edges of the short side of the main body base 30, and a pair of plate-shaped support parts 31, 32 provided on both edges of the long side. Typically, the main body base 30, the bracket attachment parts 40, 50, and the support parts 31, 32 constituting the main body 20 are formed by bending, deforming, cutting, drilling, etc., a single sheet of metal.

[0013] The main body base portion 30 is formed with an insertion hole 30a into which the threaded portion of the fastening bolt 90 is inserted. As shown in FIG. 8, the insertion hole 30a has an elliptical shape and is provided at a position offset in the longitudinal direction from the center position of the main body base portion 30. The insertion hole 30a is not limited to an elliptical shape and may be rectangular. By making the insertion hole 30a elliptical or rectangular, the movable range of the clamping portion 60 relative to the main body portion 20 can be expanded, the clamping portion 60 can be inclined relative to the main body portion 20, and its position can be adjusted, so that it can be used without design changes even if the diameter of the hanging bolt B is different.

[0014] The support portions 31 and 32 are each formed by bending at a right angle to the main body base portion 30. Gently arc-shaped recesses (first recesses) 31a and 32a are formed at the tip edges of the support portions 31 and 32, respectively. The diameter of the arc of the recesses 31a and 32a is larger than the diameter of the hanging bolt B.

[0015] The bracket mounting parts 40, 50 are each formed by bending at a right angle to the main body base part 30. A bracket mounting hole 40a, 50a is formed in the center of each bracket mounting part 40, 50. The bracket mounting holes 40a, 50a can be replaced with various structures such as a screw hole or a protrusion depending on the application of the hanging bolt support 10.

[0016] Plate-shaped guide portions 41, 42 are provided on both side edges of the bracket mounting portion 40. The guide portions 41, 42 are each formed by bending at a right angle to the bracket mounting portion 40. The guide portions 41, 42 are located outside the support portions 31, 32, and their leading edges reach the first recesses 31a, 32a of the support portions 31, 32. The corner edges on the leading edge side of the guide portions 41, 42 corresponding to the leading edge side of the main body portion 20 are cut out in a gentle curve, and guide edges 41a, 42a continuing to the first recesses 31a, 32a of the support portions 31, 32 are formed.

[0017] Plate-shaped guide portions 51, 52 are provided on both side edges of the bracket mounting portion 50. The guide portions 51, 52 are each formed by bending at a right angle to the bracket mounting portion 50. The guide portions 51, 52 are located outside the support portions 31, 32, and their leading edges reach the first recesses 31a, 32a of the support portions 31, 32. The leading edges of the guide portions 51, 52 are provided with outer recesses 51a, 52a recessed in an arc shape. The diameter of the arc of the outer recesses 51a, 52a is larger than the diameter of the hanging bolt B.

[0018] As shown in Figures 5, 6 and 7, the clamping portion 60 is configured as a groove frame having a U-shaped cross section. The depth of the clamping portion 60 is approximately equal to the depth of the inner space of the main body portion 20, and the width of the clamping portion 60 is approximately equal to the depth of the inner space of the main body portion 20. This is configured to be shorter than the width of the inner space, so that the range of motion of the clamping part 60 in the inner space of the main body part 20 is increased, and the clamping part 60 can be tilted or slid relative to the main body part 20.

[0019] Specifically, the clamping unit 60 includes a rectangular plate-shaped clamping base unit 70 and a pair of plate-shaped engaging units (hook plates) 80 provided on both edges of the long side of the clamping base unit 70. As shown in FIG. 6, a screw hole 71 that is screwed into a screw part of a fastening bolt 90 is formed in the clamping base unit 70. The screw hole 71 is provided at a position offset in the length direction from the center position of the clamping base unit 70. The insertion hole 30a formed in the main body base unit 30 and the screw hole 71 formed in the clamping base unit 70 are both provided at positions offset from the center position. This prevents the clamping unit 60 from being oriented in the wrong direction during the assembly work of inserting the clamping unit 60 into the main body unit 20 and fastening it to the fastening bolt 90, and allows the assembly work to be performed efficiently. Hook-shaped hook pieces 81, 82 are formed on the tip side of each of the pair of engaging units 80. The hook pieces 81, 82 are curved inwardly and downwardly, and their respective inner sides form gently arc-shaped hook portions (second recesses) 81a, 82a. The outer sides of the hook pieces 81, 82 form gently curved guide edges 81b, 82b. The guide edges 81b, 82b make it possible to easily guide the suspension bolt B between the guide edges 41a, 42a on the main body 20 side and the hook pieces 81, 82 on the clamping portion 60 side. The diameter of the arc of the hook portions 81a, 82a is larger than the diameter of the suspension bolt B.

[0020] The first recesses 31a, 32a of the main body 20, the hooks 81a, 82a of the clamping portion 60, and the outer recesses 51a, 52a form a hollow portion H for holding or passing the suspension bolt B.

[0021] The main body 20 and the clamping part 60 are fastened to each other at their bottom plates by a fastening bolt 90. Specifically, the fastening bolt 90 is inserted into an insertion hole 30a in the main body base part 30, and its threaded part is screwed into a screw hole 71 in the clamping base part 70. Therefore, the clamping part 60 can approach and move away from the main body 20 along the axial direction of the fastening bolt 90 within the range of the length of the fastening bolt 90.

[0022] The suspension bolt support 10 includes an elastic member that biases the main body 20 and the clamping portion 60 in a direction in which they approach each other. Here, the direction in which the main body 20 and the clamping portion 60 approach each other corresponds to a direction in which the interval of the hollow portion H between the first recesses 31a, 32a and the second recesses 81a, 82a narrows. As shown in Figs. 3, 4, and 5, a conical coil spring (elastic member) 95 is interposed between the head 91 of the fastening bolt 90 and the main body base portion 30 of the main body 20. Note that the configuration is not limited to the above as long as the main body 20 and the clamping portion 60 can be biased in a direction in which the interval of the hollow portion H between the first recesses 31a, 32a and the second recesses 81a, 82a narrows. For example, the fastening bolt 90 may be inserted from the clamping portion 60 side. In addition, the conical coil spring 95 can be replaced with a tension coil spring interposed between the main body base portion 30 and the clamping base portion 70.

[0023] Hereinafter, a distinction will be made between pre-tightening, which refers to tightening the fastening bolt 90 until the conical coil spring 95 is slightly crushed, and final tightening, which refers to tightening the fastening bolt 90 until it cannot be tightened any further, such as when the conical coil spring 95 is completely crushed.

[0024] The suspension bolt support 10 according to this embodiment is used with the fastening bolt 90 temporarily fastened. In this state, the conical coil spring 95 biases the head 91 of the fastening bolt 90 in a direction that moves the head 91 away from the main body base part 30. Since the clamping base part 70 is screwed into the fastening bolt 90, the clamping base part 70 is pulled toward the main body base part 30 (downward in FIG. 5) and overlaps and adheres closely to the main body base part 30. At this time, the hollow part H between the first recesses 31a, 32a and the second recesses 81a, 82a is configured to be narrower than the diameter of the suspension bolt B.

[0025] The suspension bolt support 10 configured in this manner is used as shown in Figures 9, 10 and 11. One feature of the suspension bolt support 10 according to this embodiment is that it has a structure that allows the suspension bolt support 10 to be temporarily fixed to the suspension bolt simply by pushing the suspension bolt support 10 into the suspension bolt. The principle by which the suspension bolt support 10 can be temporarily fixed by simply pushing it into the suspension bolt is as follows.

[0026] 9(a), the worker operates the suspension bolt support 10 so that the suspension bolt B is positioned between the guide edges 41a, 42a on the main body 20 side and the hook pieces 81, 82 on the clamping portion 60 side, and pushes the suspension bolt support 10 into the suspension bolt B. Then, the clamping portion 60 is pushed by the suspension bolt B, and rotates in the direction of the arrow R1 with the end portion P1 of the clamping base portion 70 as a fulcrum while sliding in the direction of the arrow M1. In this way, the suspension bolt B can enter toward the hollow portion H along the guide edges 41a, 42a while pushing the clamping portion 60.

[0027] 9(b), when the suspension bolt support 10 is slid relative to the suspension bolt B, the clamping portion 60 is lifted in the direction of the arrow M2 by the suspension bolt B. This allows the suspension bolt B to be accommodated in the hollow portion H.

[0028] As shown in FIG. 9(c), the first recesses 31a, 32a of the main body 20 engage with one side of the circumferential surface of the hanging bolt B housed in the hollow portion H, and the second recesses 81a, 82a of the clamping portion 60 engage with the other side of the circumferential surface of the hanging bolt B, so that the main body 20 and the clamping portion 60 firmly clamp the circumferential surface of the hanging bolt B from both sides. The holding force at this time is due to the elastic force of the conical coil spring 95, and the fastening bolt 90 is temporarily fastened so that the hanging bolt support 10 does not fall off the hanging bolt B due to its own weight. Therefore, as described in FIG. 10, the worker can adjust the height of the hanging bolt support 10 with a simple operation. The holding force described above can be adjusted by the degree to which the fastening bolt 90 is fastened. Therefore, if you want to increase the force with which the suspension bolt support 10 is temporarily fastened to the suspension bolt B, you can simply tighten the fastening bolt 90 a little, and if you want to decrease the force with which the suspension bolt support 10 is temporarily fastened to the suspension bolt B, you can simply loosen the fastening bolt 90 a little. The ability to adjust this temporary fastening force is also an important factor in being able to accommodate various thicknesses and weights.

[0029] Since the insertion hole 30a is oval and the outer width of the clamping part 60 is narrower than the inner width of the main body 20, the clamping part 60 can be slid along the arrow M1. This sliding movement is perpendicular to the direction in which the clamping part 60 is biased against the main body 20 by the conical coil spring 95, and does not require a large force. Furthermore, since the insertion hole 30a is oval, the clamping part 60 can be tilted with respect to the main body 20. Since the position where the fastening bolt 90 is screwed in the clamping base part 70 is offset from the center to the opposite side to the direction in which the hanging bolt B is pushed in, when the hanging bolt B is pressed against the hook pieces 81 and 82, the principle of leverage works and the clamping part 60 can be rotated in the direction of the arrow R1 with little force.

[0030] In this way, the worker can temporarily fasten the suspension bolt support 10 to the suspension bolt B with a simple operation of simply pushing and sliding the suspension bolt support 10 against the suspension bolt B, and with little force. The above operation is simple and can be performed with one hand, which contributes to improving the worker's workability.

[0031] The state in which the suspension bolt support 10 is temporarily fixed to the suspension bolt B can be released by the following operation. That is, as shown in FIG. 10, the head 91 of the fastening bolt 90 is pressed with a force F resisting the urging force of the conical coil spring 95, so that the clamping part 60 is separated from the main body part 20, and the hollow part H formed by the main body part 20 and the clamping part 60 can be expanded. This allows the suspension bolt support 10 to be released from the temporarily fixed state to the suspension bolt B. Of course, the above operation may be performed when the suspension bolt support 10 is temporarily fixed to the suspension bolt B. That is, instead of pressing the suspension bolt support 10 against the suspension bolt B, the above operation of pushing in the head 91 of the fastening bolt 90 may be performed while expanding the hollow part H, and then the suspension bolt B may be introduced into the hollow part H. When an operator wishes to adjust the position of the suspension bolt support 10 temporarily fixed to the suspension bolt B, the operator can press the head 91 of the fastening bolt 90 to release the temporary fixation, then move the suspension bolt support 10 to the desired position, and release the head 91 to temporarily fix the suspension bolt support 10 to the suspension bolt B.

[0032] Furthermore, for fine adjustment of the hanging bolt support 10, the worker may perform the following operation. The hanging bolt support 10 is temporarily fixed to the hanging bolt B with a clamping force that is not enough to prevent the hanging bolt support 10 from falling off the hanging bolt B, and the first recesses 31a, 32a and the second recesses 81a, 82a have a plate thickness greater than the thread groove of the hanging bolt B and are not completely fitted into the thread groove of the hanging bolt B. Therefore, in the temporarily fixed state, the worker can adjust the position of the hanging bolt support 10 by simply moving the hanging bolt support 10 in the axial direction of the hanging bolt B with a force that resists the clamping force, even without pressing the fastening bolt 90. Furthermore, by configuring the plate thicknesses of the first recesses 31a, 32a and the second recesses 81a, 82a to be thinner than the thread groove of the hanging bolt B so that the first recesses 31a, 32a and the second recesses 81a, 82a fit completely into the thread groove of the hanging bolt B, it is possible to make the hanging bolt support 10 even less likely to fall off from the hanging bolt B.

[0033] As shown in FIG. 11, once the mounting position of the suspension bolt support 10 is determined, the fastening bolt 90 is tightened from the provisionally fastened state to the final fastening. At this time, the suspension bolt support 10 is provisionally fixed to the suspension bolt B, and the main body 20 and the clamping part 60 are both fixed by the elastic force of the conical coil spring 95, so that the worker can tighten the fastening bolt 90 without holding the main body 20 by hand. This contributes to improving workability. By final fastening, the head 91 of the fastening bolt 90 does not move even when pressed, so the main body 20 and the clamping part 60 are fixed (finally fastened) in the positional relationship in the provisionally fastened state. The main body 20 and the clamping part 60 are firmly fastened by the fastening bolt 90 with the suspension bolt B sandwiched between them. The fastening force at this time is stronger than the biasing force of the conical coil spring 95 and is very strong. Therefore, the suspension bolt support 10 can be fixed to the suspension bolt B with sufficient force.

[0034] Furthermore, since the conical coil spring 95 is exposed on the surface of the hanging bolt support 10, it is possible to check whether the hanging bolt support 10 is fully or temporarily fixed to the hanging bolt B simply by looking at the conical coil spring 95.

[0035] According to the suspension bolt support 10 of the first embodiment described above, an operator can easily temporarily fasten the suspension bolt B and adjust the height with one hand, and when the height position is determined, the fastening bolt 90 is fully tightened to secure the suspension bolt B firmly. This improves the efficiency of the work. In addition, the number of parts is small, and the main body 20 and the clamping portion 60 can each be formed from a single sheet of metal, thereby reducing the manufacturing cost.

[0036] Although the conical coil spring 95 is exemplified as an elastic member for biasing the main body base portion 30 and the head 91 of the fastening bolt 90 in a direction separating them from each other from the viewpoint of the stability of the pressing operation by the operator, other elastic members such as a leaf spring may be used. Also, for example, a part of the main body base portion 30 or the clamping base portion 70 may be cut out and bent to bias the fastening bolt 90.

[0037] In the first embodiment of the support device 10 for a hanging bolt, a conical coil spring 95 is disposed between the main body portion 20 and the head 91 of the fastening bolt 90, and the hanging bolt B disposed between the main body portion 20 and the clamping portion 60 is clamped by utilizing the force that attracts the clamping portion 60 to the main body portion 20. However, the shape of the main body portion 20 and the clamping portion 60 may be configured so that the conical coil spring 95 is disposed between the main body base portion 30 and the clamping base portion 70, and the force that moves the clamping portion 60 away from the main body portion 20 can be utilized to clamp the hanging bolt B disposed between the main body portion 20 and the clamping portion 60.

[0038] The suspension bolt support 10 according to the first embodiment clamps the suspension bolt B between the main body 20 and the clamping portion 60 to temporarily fix the suspension bolt B. Therefore, the suspension bolt support 10 can be used as a rod-shaped material support that can temporarily fix a rod-shaped material such as round steel or square steel that does not have a thread groove. In this case, the clamping force can be strengthened by increasing the contact area between the main body 20 and the clamping portion 60 and the rod-shaped material and increasing the frictional force generated between them. The same effect can also be achieved by attaching pads that increase the frictional force generated between the main body 20 and the clamping portion 60 to the parts of the main body 20 and the clamping portion 60 that contact the rod-shaped material.

[0039] The suspension bolt support 10 according to the first embodiment is configured by providing recesses in both the main body 20 and the clamping portion 60 to receive the circumferential surface of the suspension bolt B. This allows the suspension bolt B guided between the first recesses 31a, 32a of the main body 20 and the second recesses 81a, 82a of the clamping portion 60 to be retained and stably clamped. In addition, the lateral movement of the clamped suspension bolt B is restricted, and the possibility that the suspension bolt support 10 will fall off the suspension bolt B can be reduced. This effect can be achieved by providing a recess in at least one of the main body 20 and the clamping portion 60. In addition, from the viewpoint of clamping the suspension bolt B between the main body 20 and the clamping portion 60, it is not necessary to provide recesses in both the main body 20 and the clamping portion 60.

[0040] Second embodiment FIG. 12 is an exploded perspective view showing a suspension bolt support 100 according to a second embodiment of the present invention. The suspension bolt support 100 can be attached to the suspension bolt B at any height position, similar to the suspension bolt support 10 described above. The major difference between the suspension bolt support 100 according to the second embodiment and the suspension bolt support 10 according to the first embodiment is that the hook pieces of the clamping portion have different shapes. The following description will focus on the clamping portion 150 of the suspension bolt support 100 according to the second embodiment. Note that the main body 110 of the suspension bolt support 100 according to the second embodiment will be described with reference numerals assigned only to necessary parts.

[0041] The clamping unit 150 includes a rectangular plate-shaped clamping base 160 and a plate-shaped engaging unit 170 formed on the edge of the long side of the clamping base 160. A screw hole 161 is provided in the center of the clamping base 160. The engaging unit 170 has an engaging plate 171, and a hole 171a is formed in the engaging plate 171. A pair of hook pieces 172 is formed on the tip side of the engaging plate 171. The pair of hook pieces 172 are curved downward inward, and each of the inner surfaces forms a gently arc-shaped hook portion (second recess) 172a, and the outer surface forms a gently curved guide edge 172b. The diameter of the arc of the hook portion 172a is larger than the diameter of the hanging bolt B.

[0042] The hook portion 172a of the clamping portion 150 and the first recesses 121a, 122a of the main body portion 110 form a hollow portion H for holding or passing the suspension bolt B therethrough.

[0043] The suspension bolt support 100 according to the second embodiment can be temporarily fixed to the suspension bolt B simply by pushing it into the suspension bolt B, based on the same principle as the suspension bolt support 10 according to the first embodiment. In addition, the position of the suspension bolt support 100 temporarily fixed to the suspension bolt B can be adjusted by a simple operation. Furthermore, the suspension bolt support 100 can be permanently fixed to the suspension bolt B by finally tightening the fastening bolt 190. In this way, the suspension bolt support 100 according to the second embodiment exerts the same effects as the suspension bolt support 10 according to the first embodiment.

[0044] The present invention is not limited to the above-mentioned embodiment, and various modifications can be made in the implementation stage without departing from the gist of the invention. In addition, the embodiments may be implemented in appropriate combination, and in that case, the combined effect can be obtained. Furthermore, the above-mentioned embodiment includes various inventions, and various inventions can be extracted by combinations selected from the multiple components disclosed.
