Description

  The present invention is applied to an attachment applied to a device (exhaust gas exhaust device) for removing exhaust gas from an automobile, and more specifically, to an apparatus that sucks exhaust gas exhausted from an automobile in a garage and discharges it outside the garage. It relates to the structure of the attachment.

  For example, in automobile production lines and assembly lines, engine adjustment and inspection are performed as appropriate. At this time, exhaust gas is discharged to the outside in order to ensure the safety of work. A device for discharging the exhaust gas to the outside has been conventionally provided (see, for example, Patent Documents 1 to 3).

  By the way, in recent years, so-called car enthusiasts are using a living room at their home as a garage, and the lifestyle of enjoying a private car in the living room is gaining popularity. In this case, the most important thing is to exhaust the exhaust gas from the garage (living) completely to the outside. Therefore, the device disclosed in Patent Document 1 cannot be diverted.

Japanese Patent No. 2967138 Japanese Patent No. 4698504 JP 2008-57409 A

  However, since the conventional apparatus is incorporated in the production line, it cannot be adapted to various automobiles having different specifications. That is, the position, size, etc. of the exhaust muffler of the private car vary depending on the vehicle type, and the conventional apparatus cannot adjust the position of the attachment for sucking the exhaust gas in accordance with the position of the muffler that changes variously. However, if the size of the attachment is large, it can be adjusted to some extent, but the suction efficiency of exhaust gas decreases and part of the exhaust gas stays in the living room, or the device becomes larger and looks great as a device installed in the living room This causes problems such as worsening.

  Therefore, the present invention has been made in view of the above circumstances, and the object of the present invention is to realize an exhaust gas exhaust device capable of reliably sucking and exhausting exhaust gas corresponding to all vehicle types. It is to provide an attachment applied to the device.

  (1) An attachment according to the present invention is an attachment applied to an exhaust gas exhaust device that sucks exhaust gas exhausted from an exhaust muffler with an intake fan and exhausts the exhaust gas to the outside. The attachment is horizontal so as to face the exhaust muffler. A pair of exhaust receivers arranged at a required pitch in the direction, a duct connected to the exhaust receiver and guiding exhaust exhausted to the exhaust receiver to a suction port of the intake fan, the pitch and upper and lower of the exhaust receiver And an adjustment mechanism for adjusting the position in the direction. The adjustment mechanism includes a base that supports the duct, a pair of support columns that extend in the vertical direction and are opposed to each other, and are slidable in a horizontal direction relative to the base. And a holder provided on the support column in a state in which the exhaust receiver is detachably held and slidable in the vertical direction.

  According to this configuration, the exhaust receiver that receives the exhaust gas is supported by the retainer and supported on the base via the support column. The pair of struts face each other, and each strut slides in the horizontal direction. Since each support | pillar hold | maintains the said holder | retainer, the distance of the exhaust receivers hold | maintained at the said holder | retainer changes when each support | pillar slides. Therefore, even if the distance between the exhaust mufflers changes depending on the vehicle type, this can be dealt with by the exhaust receivers coming into contact with each other. On the other hand, the cage can slide with respect to the support column and move up and down. Therefore, even if the height of the exhaust muffler changes depending on the vehicle type, this can be accommodated by moving the exhaust receiver up and down.

  (2) The cage is provided on each main plate in a detachable manner connected to each column, and clamps the exhaust receiver in cooperation with an opposing surface of the one main plate that faces the other main plate. And a holding tool. It is preferable that a fastening bolt that is inserted through a long hole formed in the vertical direction in each of the columns and screwed into a screw hole provided in the main plate is disposed.

  According to this configuration, since the main plate is attached to the support column, the structure for supporting the retainer on the support column is simple. In addition, since the main plate easily moves in the vertical direction only by loosening the fastening bolts, it is easy to align the exhaust receiver. In addition, by removing the fastening bolts, the main plate can be turned upside down and attached to the struts, and further can be attached to the inside or outside of a pair of opposing struts. .

  (3) The part where the exhaust receiver is held by the holding tool is preferably formed in a cylindrical shape, and the holding tool is preferably formed in a U shape so as to hold the part.

  In this configuration, even when the exhaust receiver is held by the cage, the exhaust receiver can rotate around the center of the portion. Therefore, even if the angle or posture of the exhaust receiver is easily changed and the exhaust muffler has an irregular shape, there is an advantage that it is possible to cope with this.

  According to the present invention, the position and posture of the exhaust receiver can be easily changed and the adjustment range is large, so that the exhaust gas can be reliably received in correspondence with the position of the exhaust muffler of any vehicle type.

The duct body 21 includes a discharge pipe 23, and the exhaust gas is guided to the duct body 21 and is discharged from the discharge pipe 23. The discharge pipe 23 is connected to the intake fan. By operating the intake fan, the exhaust gas in the duct body 21 is sucked through the discharge pipe 23. In the present embodiment, an aluminum alloy is used as the material constituting the duct body 21 in the same manner as the exhaust receivers 11 and 12. However, the duct main body 21 may be comprised from another metal.

  The adjusting mechanism 16 is provided on the base plate 24 (corresponding to the “base” recited in the claims), the support columns 25 and 26 that slide relative to the base plate 24, and the support columns 25 and 26, respectively. And retainers 27 and 28.

  As shown in FIGS. 1 and 2, the base plate 24 is formed of an elongated rectangular flat plate. In the present embodiment, the base plate 24 is made of an aluminum alloy, but may be made of another metal or a resin. As shown in FIG. 2, the base plate 24 supports the duct 15. In the present embodiment, the duct main body 21 is fixed on the base plate 24 via the legs 43. Further, long holes 29 to 32 are provided in the base plate 24. These long holes 29 to 32 penetrate the base plate 24 in the vertical direction 13. The long holes 29 and 30 are arranged in parallel to each other and extend in the horizontal direction 14. The long holes 31 and 32 are arranged symmetrically with the long holes 29 and 30.

  The support columns 25 and 26 include a bottom plate 33. In the present embodiment, the bottom plate 33 is a rectangular flat plate. The bottom plate 13 is made of an aluminum alloy or other metal like the base plate 24. The bottom plate 33 is disposed on the lower surface of the base plate 24, and the base plate 24 is placed on the bottom plate 33. The bottom plate 33 is provided with a pair of screw holes (not shown). The interval between the screw holes corresponds to the interval between the long holes 29 and 30.

  In this embodiment, the fastening bolt 37 is inserted into the long holes 29 to 32 and screwed into the screw holes of the bottom plate 33. As a result, the bottom plate 33 is fastened to the base plate 24. Therefore, the bottom plate 33 can slide in the horizontal direction 14 with respect to the base plate 24 by loosening the fastening bolts 37. That is, the distance between the column 25 and the column 26 is adjusted. In the present embodiment, a caster 34 is provided on the lower surface of the bottom plate 33. Thereby, the attachment 10 whole can move easily. However, the caster 34 may be omitted.

  The support | pillar 25 consists of an elongate rectangular flat plate (what is called a flat bar). The support column 25 extends in the vertical direction 13 and is orthogonal to the base plate 24. As shown in FIG. 3, a long hole 35 is formed in the center of the column 25 along the longitudinal direction. The long hole 35 penetrates the support column 25 in the horizontal direction 14. A fastening bolt 36, which will be described later, is inserted into the elongated hole 35. Note that the column 26 has the same configuration as the column 25.

  FIG. 4 is an enlarged view showing the structure of the cage 27.

  The cage 27 includes a main plate 38, a clamping tool 39, and the fastening bolt 36.

  The main plate 38 is a flat plate. As shown in FIG. 3, the main plate 38 includes a head 40 and a shaft 41 (see FIG. 1), and is formed in a substantially T shape. A screw hole (not shown) is formed in the shaft portion 41, and the fastening bolt 36 is inserted into the elongated hole 35 and then screwed into the screw hole of the shaft portion 41.

  The clamping tool 39 is provided on the main plate 38 and fixes the exhaust receivers 11 and 12 to the head 40 in cooperation with the main plate 38. As shown in FIG. 4, in the present embodiment, the holding tool 39 is a pair of bolts formed in a U shape. Male screws (not shown) are formed at both ends of the holding tool 39. That is, in this embodiment, the fixed pipes 19 of the exhaust receivers 11 and 12 are fixed to the opposing surface of the main plate 38 by a pair of bolts (clamping tool 39). Specifically, a pair of bolts is inserted through a through hole provided in the head 40 of the main plate 38, and a nut 42 is tightened from the back surface 44 of the head 40. By tightening the nut 42, the fixed tube 19 is securely fastened and fixed to the surface 45 (corresponding to “opposing surface” described in claims) of the head 40.

  Further, the fixed tube 19 can be displaced with respect to the main plate 38 by loosening the nut 42. In addition, since the fixed tube 19 is formed in a cylindrical shape in the present embodiment, the fixed tube 19 can be relatively rotated by loosening the nut 42. That is, the postures of the exhaust receivers 11 and 12 change, and the opening 20 of the receiver body 18 is inclined.

[How to use the attachment]

  Next, how to use the attachment 10 will be described.

  In order to reliably suck the exhaust gas discharged from the automobile, the exhaust receivers 11 and 12 of the attachment 10 must be arranged at the position of the exhaust muffler of the automobile.

  Since the caster 34 is provided on the attachment 10, the attachment 10 can freely move on the floor surface 17. The position adjustment (fine adjustment) of the exhaust receivers 11 and 12 is performed by the adjustment mechanism 16. That is, as described above, when the fastening bolts 36 and 37 are loosened, the receiver main body 18 can move in the horizontal direction 14 and the vertical direction 13, and the fastening bolts 36 and 37 are tightened again at the required positions. The receiver body 18 is positioned at this position. That is, as shown in FIG. 1, the receiver body 18 can be positioned in the region indicated by the two-dot chain line 46.

  Since the position of the exhaust receiver 18 is adjusted in a wide area as described above, the exhaust receiver 18 can accurately move to the position of the exhaust muffler even if the distance between the exhaust mufflers changes depending on the vehicle type. As a result, exhaust gas is reliably discharged.

  In the present embodiment, the main plate 38 is attached to the support columns 25 and 26 via the fastening bolts 36, so that the structure for supporting the retainers 27 and 28 on the support columns 25 and 26 is simple. In addition, the main plate 38 is easily moved in the vertical direction simply by loosening the fastening bolt 36, and once the fastening bolt 36 is removed, the main plate 38 is turned upside down and attached to the support columns 25, 26. Is possible.

  Specifically, as shown in FIG. 5, the main plate 38 is disposed inside the opposing struts 25 and 26 and is arranged in the up and down direction 13 (FIG. 5A) and the left and right direction 14 (FIG. 5B). Can slide. The main plate 38 can be turned upside down as shown in FIG. In this case, since the head 40 of the main plate 38 is located further downward, the position adjustment width in the vertical direction 13 of the exhaust receiver 18 is still increased. Further, as shown in FIG. 7, the main plate 38 may be disposed outside the opposing columns 25 and 26. In this case, since the head 40 of the main plate 38 is located further outside in the left-right direction 14, the position adjustment width in the left-right direction 14 of the exhaust receiver 18 is still increased. However, in the state of FIG. 7, the main plate 38 may be turned upside down.

  In addition, in this embodiment, the fixed pipes 39 of the exhaust receivers 11 and 12 are formed in a cylindrical shape, and a holding tool 39 is formed in a U shape so as to surround the fixed tube 39. Therefore, even when the exhaust receivers 11 and 12 are held by the cages 27 and 28, the fixed tube 39 can be rotated around the central axis. That is, the angle or posture of the exhaust receivers 11 and 12 can be easily changed. As a result, even if, for example, the exhaust muffler of the automobile is irregularly shaped, it can cope with this.
