Further, support pieces 27, 28 are provided on the left and right sides of the step portions 23a, 24a so as to connect between the upper surface 23 and the lower surface 24, respectively. By providing the support pieces 27, 28, deformation of the upper surface 23 and the lower surface 24 is suppressed.
Fig. 4 is a perspective view of the bumper stay 30, and fig. 5 is a rear view of the bumper stay 30. As shown in fig. 4 and 5, the bumper stay 30 includes a flat plate portion 31 having a horizontal length and a substantially rectangular square tubular portion 32. The flat plate portion 31 is attached to the periphery of an opening 101 (see fig. 2) of the bumper 100 provided in the vehicle from the rear surface (inner side) of the bumper 100. An opening 31a having a shape corresponding to the opening 101 of the bumper 100 is provided in the center of the flat plate portion 31. The square tube 32 is provided so as to project rearward from the flat plate portion 31 around the opening 31 a.
The square tube 32 is formed in a shape corresponding to the shape of the square tube 22 of the nozzle holder 20. Specifically, the rectangular tubular portion 32 has an upper surface 33 and a lower surface 34 arranged in parallel in the left-right direction, and a left side surface 35 and a right side surface 36 connected to both left and right ends of the upper surface 33 and the lower surface 34, respectively. Stepped portions 33a and 34a protruding outward (upward and downward) from both end portions are provided in the center portions of the upper surface 33 and the lower surface 34 in the lateral direction, respectively. Stepped portions 35a and 36a protruding outward (leftward and rightward) are provided at the vertical center portions of the left side surface 35 and the right side surface 36, respectively.
Two sets of ribs 33b and 33c are provided on the upper surface 33 of the square tubular portion 32 at a predetermined distance. The ribs 33b and 33c protrude upward so as to extend in the front-rear direction from a step portion 33a provided on the upper surface 33. The rear end surfaces of the ribs 33b and 33c protrude further rearward from the rear end surface of the square tubular portion 32. The right rib portion 33c of the pair of rib portions 33b and 33c includes a projecting portion 33d projecting rightward from the lower surface portion thereof. Two sets of ribs 34b and 34c are provided on the lower surface 34 of the square tubular portion 32 at a predetermined distance. The ribs 34b and 34c protrude downward so as to extend in the front-rear direction from a step portion 34a provided on the lower surface 34. The rear end surfaces of the ribs 34b and 34c project further rearward from the rear end surface of the square tubular portion 32. The right rib portion 34c of the pair of rib portions 34b and 34c includes a projecting portion 34d projecting rightward from the upper surface portion thereof.
The left side surface 35 and the right side surface 36 of the square tubular portion 32 are provided with elastic locking pieces 37 and 38 projecting rearward, respectively. Oblong locking holes 37a and 38a are formed in the elastic locking pieces 37 and 38.
Next, a method of attaching the bumper stay 30 to the bumper 100, and a method of attaching the nozzle stay 20 holding the nozzle assembly 10 to the bumper stay 30 attached to the bumper 100 will be described with reference to fig. 6 to 10. Fig. 6 is a perspective view showing a state in which the nozzle bracket 20 is attached to the bumper bracket 30. Fig. 7 is a rear view in the state of fig. 6. Fig. 8 is a sectional view a-a of fig. 7. Fig. 9 is a partially enlarged side view in the state of fig. 6. Fig. 10 is a sectional view B-B of fig. 9.
First, the operator mounts the nozzle bracket 20 to the nozzle assembly 10. Specifically, the operator inserts the rear end of the cylinder 11 of the nozzle assembly 10 from the front end of the nozzle holder 20, moves the nozzle assembly 10 rearward relative to the nozzle holder 20, and engages the locking piece 11a provided in the cylinder 11 with the locking hole 21a provided in the cylindrical portion 21 of the nozzle holder 20.
Next, the worker attaches the bumper stay 30 to the bumper 100. Specifically, the operator moves the bumper stay 30 from the inside of the bumper 100 in the front-rear direction (the advancing-retreating direction of the piston) toward the bumper 100, thereby attaching the bumper stay 30 to a predetermined position where the opening 101 of the bumper 100 is formed. That is, the worker performs the work of attaching the bumper stay 30 to the bumper 100 in the space provided on the rear surface side of the bumper 100. An adhesive is adhered to a surface of the flat plate portion 31 of the bumper stay 30 facing the bumper 100. Although not shown, the bumper stay 30 may be attached to the bumper 100 by fastening with screws or the like.
Next, the operator attaches the nozzle holder 20 holding the nozzle assembly 10 to the bumper holder 30 from the inside of the opening 101 of the bumper 100. Specifically, the operator moves the nozzle holder 20 from the inside of the opening 101 toward the bumper holder 30 in the front-rear direction (the forward-backward direction of the piston 12). Thereby, the elastic locking piece 37 formed in the bumper stay 30 is guided between the ribs 25b and 25c formed in the nozzle stay 20, and the elastic locking piece 38 is guided between the ribs 26b and 26 c. As shown in fig. 8 and the like, the rear ends of the elastic locking pieces 37 and 38 pass over engaged portions (protruding portions) 25a and 26a formed in the nozzle holder 20, and the engaged portions 25a and 26a are engaged with locking holes 37a and 38a formed in the elastic locking pieces 37 and 38. In this way, the nozzle assembly 10 held by the nozzle holder 20 can be assembled to the bumper holder 30 attached to the bumper 100.
The worker who attaches the nozzle holder 20 to the nozzle assembly 10 is, for example, a manufacturer of the cleaner 1. The worker who attaches the bumper stay 30 to the bumper 100 and the worker who attaches the nozzle stay 20 to the bumper stay 30 are, for example, manufacturers of vehicles. The operator who attaches the nozzle holder 20 to the nozzle assembly 10, the operator who attaches the bumper holder 30 to the bumper 100, and the operator who attaches the nozzle holder 20 to the bumper holder 30 may be the same operator.
As shown in fig. 6 and 9, in a state where the engaged portions 25a, 26a are engaged with the locking holes 37a, 38a of the elastic locking pieces 37, 38 (hereinafter, sometimes referred to as an assembled state), the front end surface of the square tube portion 22 of the nozzle holder 20 abuts against the rear end surface of the square tube portion 32 of the bumper holder 30. As shown in fig. 6, 7, and 10, in the assembled state, the stepped portion 23a of the upper surface 23 of the nozzle bracket 20 is disposed between the ribs 33b and 33c of the upper surface 33 of the bumper bracket 30, and the stepped portion 24a of the lower surface 24 of the nozzle bracket 20 is disposed between the ribs 34b and 34c of the lower surface 34 of the bumper bracket 30. At this time, the rib 33b on the left side among the ribs 33b, 33c provided on the upper surface 33 of the bumper stay 30 is guided into the guide portion 23c provided between the step portion 23a and the rib 23b of the upper surface 23 of the nozzle stay 20. In this manner, the nozzle holder 20 is positioned with respect to the bumper holder 30.
As described above, the cleaner 1 according to the present embodiment includes: a nozzle holder 20 which is provided in an opening 101 formed in the bumper 100 and has a cylindrical shape; a nozzle assembly 10; and a bumper stay 30. The nozzle assembly 10 has: a cylinder 11 supported by the nozzle bracket 20; a piston 12 supported to be movable in and out of the cylinder 11; and nozzles 13, 13 disposed near the front end of the piston 12 and jetting a cleaning liquid toward an object to be cleaned of the vehicle in a state where the piston 12 protrudes from the opening 101. The bumper stay 30 can be attached to the bumper 100 from the inside of the opening 101, and the nozzle unit 10 is positioned with respect to the opening 101 in a state of being engaged with the nozzle stay 20. The bumper stay 30 has elastic locking pieces 37 and 38 formed to protrude toward the inside of the opening 101 in the advancing and retreating direction of the piston 12, and the nozzle stay 20 can be attached to the bumper stay 30 by moving the nozzle stay 20 in the advancing and retreating direction of the piston 12 to engage the elastic locking pieces 37 and 38 with engaged portions 25a and 26a formed in the nozzle stay 20. As described above, according to the cleaner 1 of the present embodiment, the bumper stay 30 can be attached to the bumper 100 by moving the bumper stay 30 in the advancing and retreating direction of the piston 12 from the inside of the opening 101 provided in the bumper 100, and the nozzle stay 20 can be attached to the bumper stay 30 by moving the nozzle stay 20 in the advancing and retreating direction of the piston 12. In particular, when the nozzle holder 20 holding the nozzle assembly 10 is attached to the bumper holder 30, the operator can finish the attachment by moving the cylinder 11 in one direction while holding it. That is, when the nozzle unit is assembled to the bumper, it is not necessary to rotate the nozzle unit in the circumferential direction of the cylinder or to twist the nozzle unit in the vertical direction or the horizontal direction as in the conventional case. Therefore, even if the working space when the nozzle assembly 10 is assembled into the opening 101 of the bumper 100 is small, the working efficiency is not reduced, and the assembling property of the cleaner 1 to the bumper 100 can be improved.
In the cleaner 1 according to the present embodiment, the bumper stay 30 includes ribs 33b and 34b (an example of a first rib) that protrude in the advancing and retreating direction of the piston 12, and ribs 33c and 34c (an example of a second rib) that protrude in the advancing and retreating direction of the piston 12 and have a shape different from that of the rib 33 b. Then, the nozzle holder 20 has a guide portion 23c, and the guide portion 23c can be engaged with the ribs 33b and 34b and cannot be engaged with the ribs 33c and 34c having the extension portions 33d and 34 d. When the nozzle holder 20 is attached to the bumper holder 30 in the state shown in fig. 7 and 10, the rib 33b of the upper surface 33 of the bumper holder 30 is inserted into the guide portion 23c of the nozzle holder 20. On the other hand, the state shown in fig. 7 and 10 means that when the nozzle holder 20 is attached to the bumper holder 30 in a state where the nozzle holder 20 is rotated 180 degrees in the circumferential direction of the piston 12, the rib 34c of the lower surface 34 of the bumper holder 30 comes to the position of the guide portion 23c of the nozzle holder 20, and therefore the protruding portion 34d of the rib 34c interferes with the rib 23b constituting the guide portion 23 c. Therefore, in this state, the rib 34c cannot be inserted into the guide portion 23c, and the nozzle holder 20 cannot be assembled to the bumper holder 30. As described above, the nozzle holder 20 according to the present embodiment is shaped such that the nozzle holder 20 cannot be attached to the bumper holder 30 in a direction different from the appropriate state (the state of fig. 7 and 10), and therefore erroneous assembly of the nozzle assembly 10 can be prevented.
In addition, the cleaner 1 according to the present embodiment has the following configuration: the engaged portions 25a, 26a are disposed on the outer side of the nozzles 13, 13 on the surface orthogonal to the advancing and retreating direction of the piston 12, and the elastic locking pieces 37, 38 are engaged with the engaged portions 25a, 26a from the outer side of the engaged portions 25a, 26 a. Accordingly, since a certain space can be provided between the nozzles 13, 13 and the elastic locking pieces 37, 38, when the nozzle holder 20 holding the nozzle assembly 10 is attached to the bumper holder 30, the elastic locking pieces 37, 38 can be prevented from colliding with the nozzles 13, 13 to cause positional displacement of the nozzles 13, 13 or damage to the nozzles 13, 13.
Further, as shown in fig. 5, the bumper stay 30 is preferably formed to be vertically symmetrical. This allows the bumper stay 30 to be engaged with the bumper 100 by reversing the vertical direction of the bumper stay 30 from the assembly direction shown in fig. 3 and 4. Therefore, the assembly direction of the bumper stay 30 with respect to the bumper 100 is not restricted. Further, the bumper stay may be formed to be vertically asymmetrical.
In the above embodiment, the elastic locking pieces 37 and 38 of the bumper stay 30 are configured to engage with the engaged portions 25a and 26a of the nozzle stay 20 from the outside of the engaged portions 25a and 26a, but the present invention is not limited to this example. For example, a projecting engaged portion may be provided on the inner side of the left and right side surfaces of the nozzle holder, and the elastic locking piece of the bumper holder may be inserted into the nozzle holder to engage the elastic locking piece with the engaged portion provided on the left and right side surfaces of the nozzle holder from the inner side. According to this configuration, the operator can complete the attachment to the bumper stay by moving the nozzle unit and the nozzle stay in one direction while holding the cylinder, and thus the ease of assembling the cleaner to the bumper can be improved.
In the above embodiment, the ribs 33b and 34b and the ribs 33c and 34c having the protruding portions 33d and 34d are provided on both the upper surface 33 and the lower surface 34 of the bumper stay 30, but the present invention is not limited to this example. For example, when only the rib 33b of the upper surface 33 of the upper and lower ribs 33b, 34b is provided, the rib 34c may be provided on the opposite side to the rib 33b with respect to the nozzle assembly 10 interposed therebetween. When only the rib 34b on the lower surface 34 of the upper and lower ribs 33b, 34b is provided, the rib 33c may be provided on the opposite side to the rib 34b with respect to the nozzle assembly 10. With these configurations, erroneous assembly of the nozzle assembly 10 can also be prevented.
In the above embodiment, the elastic locking pieces 37 and 38 are configured to directly protrude rearward from the left side surface 35 and the right side surface 36 of the bumper stay 30, but the present invention is not limited to this example. For example, one of the elastic locking pieces may protrude rearward from the flat plate portion on the left side of the left side surface of the bumper stay, and the other elastic locking piece may protrude rearward from the flat plate portion on the right side of the right side surface of the bumper stay. In this configuration, the opening of the flat plate portion formed as the internal space of the upper surface, the lower surface, the left side surface, and the right side surface of the bumper stay, and the opening 101 of the bumper 100 can be minimized.
Although the embodiments of the present invention have been described above, it goes without saying that the technical scope of the present invention is not limited to the description of the embodiments. The present embodiment is merely an example, and those skilled in the art will understand that various modifications of the embodiment can be made within the scope of the invention described in the claims. The technical scope of the present invention should be determined based on the scope of the invention described in the claims and the scope equivalent thereto.
