Description

Raceway arrangement

Background

The present invention relates to a raceway arrangement, and more particularly to a raceway arrangement positioned on a top plate to secure a structure to a lower portion of the top plate.

Generally, a raceway apparatus is provided on a ceiling in a building to make a lighting device or a running rail along which a vehicle fixed to the ceiling travels.

According to the related art, the lighting device or the travel rail may be directly fixed to the ceiling plate using hanger bolts. Further, the raceway device is fixed to the top plate using hanger bolts, and the lighting apparatus or the travel rail is fixed to the raceway device. Thus, the lighting device or the travel rail is fixed to the top plate by the raceway arrangement.

Since the hanger bolts may secure structures, such as lighting fixtures, travel rails, and raceways, in a single point support, this may concentrate the loads on the structure on the hanger bolts. Therefore, it is difficult to stably fix the structure to the top plate.

Disclosure of Invention

The present invention provides a raceway apparatus which stably fixes structures such as a lighting device, a running rail, and a raceway on a top plate and is simple to mount.

According to an aspect of the present invention, the raceway device includes a plurality of mold bars spaced apart from each other at predetermined intervals and fixed to the top plate; a raceway provided below the die bar and extending in a direction perpendicular to the die bar, the raceway having a flange on an upper surface thereof; and a bolt and nut for each combining the flange of the raceway with each mold bar to fix the raceway to the mold bar.

According to some exemplary embodiments of the present invention, a T-shaped groove may be formed on a lower surface of each of the mold bars in an extending direction of the mold bars, each of the bolts may have a T-shaped head to be inserted into the T-shaped groove through a flange of the raceway, and the nuts may be fastened to the bolts, respectively.

According to some exemplary embodiments of the present invention, a T-shaped groove may be formed on a lower surface of each of the mold bars in an extending direction of the mold bars, a nut may be inserted into the T-shaped groove, and bolts may be fastened to the nut through flanges of the raceways, respectively.

According to an aspect of the present invention, the raceway device includes a plurality of mold bars spaced apart from each other at predetermined intervals and fixed to the top plate; a plurality of curved plates each disposed below the mold bar and having a flange; a first bolt and a first nut for combining each of the bent plates and each of the mold bars to fix the bent plates to the mold bars, respectively; a raceway provided below the bent plate and extending in a second direction perpendicular to the first direction; and a second bolt and a second nut for combining each of the curved plates and each of the raceways to fix the raceways to the curved plates.

According to some exemplary embodiments of the present invention, T-shaped first grooves may be formed on a lower surface of each of the mold bars in an extending direction of the mold bars, each of the first bolts may have a T-shaped head to be inserted into the T-shaped first grooves through a flange of the bent plate, and the first nuts may be fastened to the first bolts, respectively.

According to some exemplary embodiments of the present invention, T-shaped second grooves are formed on both sides of the raceway in an extending direction of the raceway, elongated through holes extending in the extending direction of the raceway are formed on both sides of the bent plate, each of the second bolts may have a T-shaped head to be inserted into the second groove through the through hole of the bent plate, and second nuts may be fastened to the second bolts, respectively.

According to an exemplary embodiment of the present invention, a flange is formed on each raceway and curved plate, and the die rods and the raceways or the die rods and the curved plates are joined in a multi-point supporting manner of two or more points using the flanges, not in a single-point supporting manner. Accordingly, the load applied to the connection points of the mold bars is dispersed so that the mold bars can stably fix the raceway or the bending plate.

Further, the die rods and the raceways or the die rods and the bending plate are fastened to each other by using T-shaped grooves formed on the lower surface of the die rods and passing each bolt having a T-shaped head through the flange of each raceway and bending plate. Since the die rods and the raceways or the die rods and the bent plates can be easily fastened, the raceway arrangement can be easily installed.

Fig. 1 is a front view showing a raceway apparatus according to an exemplary embodiment of the present invention, fig. 2 is a side view showing the raceway apparatus as shown in fig. 1, and fig. 3 is a perspective view showing a bolt and a nut having a T-shaped head as shown in fig. 1.

Referring to fig. 1 to 3, the raceway apparatus 100 includes a mold bar 110, a raceway 120, a bolt 130, and a nut 140.

The mold bars 110 are spaced apart from each other at a predetermined interval and fixed to the top plate. For example, each of the mold bars 110 may extend in a first direction, i.e., in a left-right direction. The mold bars may be spaced apart from each other at predetermined intervals to be arranged in a direction perpendicular to the first direction, i.e., a front-rear direction.

The mold bar 110 may be directly fixed to the top plate or separately fixed from the top plate using an additional member.

A groove 112 is formed on the lower surface of the mold bar 110. The grooves 112 are elongated in a first direction corresponding to the extending direction of the mold bar 110, i.e., the left-right direction. Here, the groove 112 may be formed to extend to both ends of the mold bar 110.

When the groove 112 is cut in a vertical direction perpendicular to the first direction, the cross section of the groove 112 is substantially T-shaped.

Specifically, the trench 112 has a lower trench portion 112a and an upper trench portion 112 b.

The lower groove portion 112a is provided on the lower surface of the die bar 110 to have a first width measured in a first direction.

The upper groove portion 112b is provided on an upper portion of the lower groove portion 112a and is connected to the lower groove portion 112 a. The upper groove portion 112b has a second width larger than the first width measured in the first direction.

The raceway 120 may be disposed below the die bar 110 and may extend in a second direction, i.e., a front-to-rear direction perpendicular to the first direction. Here, the raceways 120 may be spaced apart from each other in the left-right direction to be arranged in the first direction.

Each of the raceways 120 includes a flange 122. A flange 122 may be provided on the upper surface of the raceway 120. The width of the flange 122 is greater than the width of each of the raceways 120. Flanges 122 are used to secure each of the raceways 120 to each of the mold bars 110.

On the other hand, additional grooves may be formed on both side surfaces and the lower surface of the raceway 120, respectively. And turnbuckles, hanging bolts and the like are arranged on the additional grooves, and the turnbuckles and the hanging bolts can fix a traveling track along which the lighting equipment or the vehicle travels.

Bolts 130 and nuts 140 may secure each of the raceways 120 to each of the mold bars 110. Here, it is preferable that two bolts 130 and two nuts 140 are provided at each fixing position, but more than two bolts 130 and two nuts 140 may be provided.

Specifically, as shown in fig. 3, the bolt 130 is a T-shaped bolt having a T-shape to include a head portion extending in one direction. A width in a short direction of the head of the bolt 130 may be equal to or less than a first width of the lower groove portion 112a, and a width in a long direction of the head of the bolt 130 may be greater than the first width of the lower groove portion 112a and equal to or less than a second width of the upper groove portion 112 b.

In a state in which the extending direction of the head of the bolt 130 is aligned with the extending direction of the groove 112, the head of the bolt 130 is lifted to the upper groove portion 112b through the lower groove portion 112a, and then the bolt 130 is rotated by 90 degrees so that the bolt 130 can be mounted in the groove 112 of the mold bar 110.

Each of the bolts 130 also passes through the flange 122 of the raceway 120.

When each of the bolts 130 passes through the flange 122 of the raceway 120 to be mounted in each of the grooves 112 of the mold bar 110, the nuts 140 are fastened to the bolts 130, respectively.

The process of fixing the mold bars 110 and the raceways 120 using the bolts 130 and nuts 140 will be explained in detail below.

Each of the bolts 130 is inserted through the flange 122 from above the raceway 120. After aligning the mold bar 110 with the raceway 120, the lower surface of the mold bar 110 and the upper surface of the raceway 120 are brought into close contact with each other so that the bolts 130 are brought into contact with the grooves 112 of the mold bar 110. Here, the extending direction of the head of the bolt 130 is aligned with the extending direction of the groove 112.

The head of the bolt 130 is lifted up to the upper groove portion 112b through the lower groove portion 112a, and then the bolt 130 is rotated by 90 degrees so that the bolt 130 is mounted in the groove 112 of the mold bar 110.

Next, nuts 140 are fastened to the bolts 130 installed in the grooves 112 of the mold bars 110 and arranged to pass through the flanges 122 of each of the raceways 120, respectively, so that the raceways 120 can be fixed to the mold bars 120.

Meanwhile, although not shown, the bolts 130 and the nuts 140 may fix the raceways 120 to the mold bars 110 in a different manner from that of fig. 1 and 2.

Specifically, the nut 140 is inserted into the upper groove portion 112b through both side surfaces of the mold bar 110. Here, the width of the nut 140 may be greater than the first width of the lower groove portion 112a and may be equal to or less than the second width of the upper groove portion 112 b. Therefore, the nut 140 inserted into the upper groove portion 112b is not released downward from the mold stem 110 by the lower groove portion 112 a.

After aligning the mold bar 110 and the raceway 120, the lower surface of the mold bar 110 and the upper surface of the raceway 120 are in close contact with each other. Next, the bolts 130 pass through the flanges 122 from below the raceway 120 and then the bolts 130 are fastened to the nuts 140 inserted into the upper groove portions 112b, respectively. Here, the bolt 130 may be a T-bolt or a general bolt.

The die bar 110 and raceway 120 can be simply and quickly fastened by using the groove 112 of the die bar 110 and the bolt 130 having a T-shaped head that passes through the flange 122 of the raceway 120. Therefore, the raceway apparatus 100 can be quickly and easily mounted on the top plate.

Since each of the raceways 120 has the flange 122, the mold bar 110 and the raceway 120 can be fixed in a multi-point supporting manner of two or more points instead of a one-point supporting manner using the flange 122, the bolt 130, and the nut 140. Accordingly, the load applied to the fixing point of the mold bar 110 is dispersed so that the mold bar 110 can stably fix the raceway 120.

Fig. 4 is a front view showing a raceway apparatus according to another exemplary embodiment of the present invention, and fig. 5 is a side view showing the raceway apparatus as shown in fig. 4.

Referring to fig. 4 and 5, the raceway apparatus 200 includes a mold bar 210, a bent plate 220, a first bolt 230, a first nut 240, a raceway 250, a second bolt 260, and a second nut 270.

The detailed description about the mold bar 210 and the T-shaped first groove 212 including the lower groove 212a and the upper groove 212b is substantially the same as the description about the mold bar 110 and the groove 112 including the lower groove portion 112a and the upper groove portion 112b with reference to fig. 1 to 3, and thus omitted.

A plurality of curved plates 220 are spaced apart from each other below the mold bar 210. The curved plate 220 is curved in a downward direction. For example, curved plate 220 may be substantially U-shaped.

A flange 222 is provided on an upper surface of each of the curved plates 220. The width of the flange 222 is greater than the width of each of the curved plates 220 and the flange 222 is used to secure each of the curved plates 220 to each of the mold bars 210.

The first bolt 230 and the first nut 240 fix the bent plate 220 to the mold bar 210.

The detailed description about fixing the bent plate 220 to the mold bar 210 using the first bolt 230 and the first nut 240 is substantially the same as the description about fixing the raceway 120 to the mold bar 110 using the bolt 130 and the nut 140 with reference to fig. 1 to 3, and thus is omitted.

The die stem 210 and the bent plate 220 can be simply and quickly fastened by using the T-shaped first groove 212 of the die stem 210 and the first bolt 230 having a T-shaped head passing through the flange 222 of the bent plate 220. Therefore, the raceway apparatus 200 can be quickly and easily mounted on the top plate.

Further, since each of the bent plates 220 has the flange 222, the mold bar 210 and the bent plate 220 may be fixed in a multi-point supporting manner of two or more points, rather than a single-point supporting manner, using the flange 222, the first bolt 230, and the first nut 240. Accordingly, the load applied to the fixing point of the mold bar 210 is dispersed so that the mold bar 210 can stably fix the bent plate 220.

The bent plate 220 is provided with at least one through hole 224 on both side surfaces thereof, respectively. Here, the through hole 224 may be an elongated hole extending in the front-rear direction.

The raceway 250 may be disposed below the bent plate 220 and may extend in a front-rear direction perpendicular to a left-right direction in which the mold bar 210 extends. Here, the raceways 250 may be spaced apart from each other in the left-right direction.

The second grooves 252 may be formed on both sides of the raceway 250 in the extending direction of the raceway 250.

When the second grooves 252 are cut in the vertical direction perpendicular to the front-rear direction, the cross section of the second grooves 252 is substantially T-shaped.

Specifically, the second groove 252 has an outer groove 252a and an inner groove 252 b.

Outer grooves 252a are disposed on both sides of raceway 250 and have a third width.

The inner groove 252b is disposed on an inner side of the outer groove 252a, is connected to the outer groove 252a, and has a fourth width greater than the third width.

On the other hand, a groove may also be formed on the lower surface of the raceway 220. The grooves are provided with turnbuckles, hanging bolts and the like which can fix a traveling track on which the lighting equipment or the vehicle travels.

A second bolt 260 and a second nut 270 secure the raceway 250 to the curved plate 220. Here, it is preferable that two second bolts 260 and two second nuts 270 are provided for each fixing portion, but two or more second bolts 260 and two or more second nuts 270 may be provided.

Specifically, the second bolt 260 is a T-shaped bolt having a T-shape in which a head of the second bolt 260 extends in one direction. A width in a short direction of the head of the second bolt 260 may be equal to or less than the third width of the outer groove 252a, and a width in a long direction of the head of the bolt 260 may be greater than the third width of the outer groove 252a and equal to or less than the fourth width of the inner groove 252 b. Here, the head size of the second bolt 260 may be substantially equal to or slightly smaller than the size of the through hole 224 of the bent plate 220. Accordingly, the second bolt 260 may be inserted through the through hole 224.

In a state in which the extending direction of the head of the second bolt 260 is aligned with the extending direction of the second groove 252, the head of the second bolt 260 is inserted into the inner groove 252b through the through hole 224 and the outer groove 252a, and then the second bolt 260 is rotated by 90 degrees so that the second bolt 260 can be mounted in the T-shaped second groove 252 of the raceway 250.

Second nuts 270 are fastened to the second bolts 260, respectively, and the second bolts 260 are installed in the second grooves 252 of the raceways 250 and arranged to pass through the through holes 224 of the bent plate 220.

Since the at least one through hole 224 is respectively provided on both sides of the curved plate 220, so that the at least one second bolt 260 and the second nut 270 can be respectively provided on both sides of the curved plate 220.

The process of fixing the bent plate 220 and the race 250 using the second bolt 260 and the second nut 270 is as follows.

The raceway 250 is inserted into the bent plate 220, and then the bent plate 220 and the raceway 250 are aligned such that the through-hole 224 of the bent plate 220 and the second groove 252 of the raceway 250 are located at the same height.

The head of the second bolt 260 is inserted into the inner groove 252b through the through hole 224 and the outer groove 252a, and then the second bolt 260 is rotated by 90 degrees so that the second bolt 260 can be mounted in the T-shaped second groove 252 of the raceway 250.

Next, second nuts 270 are fastened to the second bolts 260, respectively, and the second bolts 260 are installed in the second grooves 252 of the raceways 250 and arranged to pass through the through holes 224 of the curved plate 220, so that the raceways 250 can be fixed to the curved plate 220.

Meanwhile, although not shown, unlike fig. 4 and 5, a second bolt 260 and a second nut 270 may fix the raceway 250 to the curved plate 220.

Specifically, a pair of second nuts 270 are inserted into the inner grooves 252b through both sides of the raceway 250. Here, the width of the second nut 270 may be greater than the third width of the outer groove 252a and may be equal to or less than the fourth width of the inner groove 252 b. Therefore, the second nut 270 inserted into the inner groove 252b is not released to both sides of the raceway 250 through the outer groove 252 a.

After the raceway 250 is inserted into the bent plate 220, the bent plate 220 and the raceway 250 are aligned such that the through-hole 224 of the bent plate 220 and the second groove 252 of the raceway 250 are located at the same height.

The second bolts 260 are inserted into the inner grooves 252b from both sides of the bent plate 220 through the through holes 224 of the bent plate 220 and the outer grooves 252a of the raceways 250 and then the second bolts 260 are fastened to the second nuts 270 inserted into the inner grooves 252b, respectively. Here, the second bolt 260 may be a T-bolt or a general bolt.

The curved plate 220 and the raceway 250 can be simply and rapidly fastened by using the through-hole 224 of the curved plate 220 having the long hole shape, the T-shaped second groove 252 of the raceway 250, and the second bolt 260. Thus, the raceway assembly 200 can be quickly and easily mounted on the top plate.

Although the raceway arrangement has been described with reference to particular embodiments, it is not limited thereto. Accordingly, it will be readily understood by those skilled in the art that various modifications and changes can be made thereto without departing from the spirit and scope of the present invention as defined by the appended claims.
