Behind the seat S, there are disposed a rear cowl R that covers the upper part of the rear wheel Wr driven by the power unit P, and a carrier frame Cf that is positioned above the rear cowl R with a space therebetween. A pair of left and right side covers Sc that bulge outward from the left and right sides of the rear cowl R, and an exhaust muffler M that extends through the one side cover Sc and extends rearward of the vehicle body are disposed. The rear cowl R, the side cover Sc, and the exhaust muffler M are all fixed to the vehicle body frame F by known fixing means, and the front end portion of the carrier frame Cf is connected to the rear portion of the seat S and the upper portion of the side cover Sc. It is integrally fastened to the vehicle body frame F with mounting bolts B that are fastened together with F. Further, below the carrier frame Cf, a pair of left and right winker lamps Rw are provided on the left and right outer sides of the rear cowl R, and a tail lamp Rt is provided on the upper surface of the rear half of the rear cowl R.
[0013]
Next, the structures of the carrier frame Cf and the auxiliary carrier Cs will be specifically described with reference to FIGS. The carrier frame Cf is substantially U-shaped by a pair of left and right vertical rods 1 and 1 extending in the front-rear direction and a horizontal rod 2 extending in the left-right direction so as to integrally connect the rear ends of both vertical rods 1 and 1. In order to reinforce the carrier frame Cf, a plurality of horizontal bars 2 ₁ to 2 ₃ are integrated between the vertical bars 1 and 1 apart from the horizontal bar 2 with a space in front and rear. Are horizontally connected. Between the second row transverse rod 2 ₂ and cowl R of the connecting piece 12 is integrally connected to connecting together therebetween. Thus to Tate杆In this embodiment 1,1 in the first frame portion of the present invention, also Yoko杆2 _2, 2 ₃ correspond to the second frame portion of the present invention.
[0014]
The front portion of each vertical rod 1 is inclined and extended forward and downward so as to wrap around the lower portion of the rear end of the sheet S, and a flat portion 1a through which the bolt B is inserted is formed at the front end portion. . In addition, a plurality of locking legs 3 for hanging a rope (not shown) such as a luggage fixing string are integrally suspended from the lower surface of each vertical rod 1 at intervals. Further the left and right Tate杆1,1, and the sheet S rear, the space surrounded by the horizontal rod 2 ₂ of the second column, the tail bag 4 that functions as a glove compartment is disposed, the bag 4 is known Are fixed to the carrier frame Cf in a detachable manner using the fixing means (fixed string 13 in the illustrated example). The tail bag 4 is provided with a lid 6 that can be opened and closed by a known opening / closing means (fastener 5 in the illustrated example). By opening the lid 6 at any time, it is possible to load and unload luggage into the bag 4. .
[0015]
The auxiliary carrier Cs is integrally connected to an auxiliary carrier main body 7 that extends outward from the carrier frame Cf to form an auxiliary luggage placing portion and a base end of the auxiliary carrier main body 7. And a hook piece 10. The auxiliary carrier body 7 has a pair of main rods 8 and 8 arranged at a distance in the front-rear direction and a connecting rod 9 that integrally connects the main rods 8 and 8 and has a substantially U-shape. It is formed. At each base portion of the main rods 8 and 8, there is a concave curved portion 8a as a fulcrum portion that can be placed and engaged with one longitudinal rod 1 (first frame portion) of the carrier frame Cf so as to straddle from above. Each is provided. The concave curved portion 8a may be formed by plastic working a part of the main shaft 8 in a substantially upper semicircular arc shape as shown in the drawing, or when the main shaft 8 has a relatively large diameter, You may form it by cutting a downward ditch on the lower surface of the base.
[0016]
A pair of hook pieces 10, 10 that are substantially orthogonal to the main rods 8, 8 are integrally formed at the base ends of the pair of main rods 8, 8, respectively. The tips are formed inward so that the tips approach each other. These hook pieces 10, 10 are placed on the side frames 2 ₂ , 2 ₃ (second frame portion) of the carrier frame Cf so as to restrict the rotation of the auxiliary carrier body 7 around the concave curved portion 8 a (fulcrum portion). The engagement piece of the present invention that can be engaged from the side, which functions as an action point that causes the carrier frame Cf to receive the moment generated in the auxiliary carrier body 7 around the concave curved portion 8a (fulcrum portion). Can be fulfilled. Each hook piece 10 has a locking step portion 10 a that can be locked to the corresponding horizontal ribs 2 ₂ , 2 ₃ so as not to move in the front-rear direction (that is, the direction along the vertical hook 1) from the base end of the main rod 8. The locking step portion 10a may be formed by plastic processing a part of the hook piece 10 in a descending step shape or a substantially lower semicircular arc shape as shown in the figure. Further, when the hook piece 10 has a relatively large diameter, it may be formed by cutting an upward concave groove on the upper surface thereof.
[0017]
Thus, since the auxiliary carrier Cs is entirely composed of an elastically deformable frame material such as a metal frame, when the auxiliary carrier Cs is mounted on the carrier frame Cf, the auxiliary carrier body 7 is elastically deformed. If the distance between the hook pieces 10, 10 connected to the base ends of the front and rear main rods 8, 8 is increased, the hook pieces 10, 10 pass through the horizontal rods 2 ₂ , 2 ₃ (second frame portion). If the auxiliary carrier main body 7 is restored to its original form by its own elastic restoring force after passing through it, the engaging stepped portion 10a of each hook piece 10 is placed on the side 2 ₂ , 2 ₃ (second frame portion) can be locked without difficulty. Also when releasing such a locked state, if the auxiliary carrier body 7 is elastically deformed to increase the mutual distance between the front and rear hook pieces 10 and 10 in the same manner as described above, It is possible to detach from the sides 2 ₂ and 2 ₃ without difficulty.
[0018]
Next, the operation of the embodiment will be described. If there is no load to be placed on the carrier frame Cf or if it is small, the auxiliary carrier Cs does not need to be used and is stored in an appropriate storage location such as the tail bag 4. Thereby, there is no possibility that the auxiliary carrier Cs impairs the appearance of the carrier frame Cf, and there is no fear of losing the auxiliary carrier Cs.
[0019]
Further, when a large load (see reference A in FIG. 5) that protrudes to the left and right from the original placement surface is loaded on the carrier frame Cf, a part of the load is below both sides of the carrier frame Cf. In such a case, the rear turn signal lamp Rw may be concealed by the hanging luggage, or a part of the luggage may come into contact with the hot exhaust muffler M. Therefore, when loading such a large load, a pair of auxiliary carriers Cs is taken out from the tail bag 4 or the like, and they are placed on the carrier frame Cf so that the concave curved portion 9a as a fulcrum portion as shown in FIG. Tate杆so that placing the hooks 10 of the and the engagement piece respectively engaged from above on 1 Yoko杆2 _2, 2 ₃ predetermined mounting state of engaged from the lower side, respectively.
[0020]
During this attachment, for example by engaging the front and rear one of hooks 10 (engaging step portion 10a) is first in one lateral rod 2 _2, the engagement elastically deforming the auxiliary carrier Cs while maintaining (i.e. pair of main The flanges 8 and 8 are expanded and deformed) so that the distance between the front and rear hook pieces 10 and 10 is increased. And in this state, the other hooks 10 moves the auxiliary carrier Cs until it passes other transverse rod 2 _3, then the auxiliary carrier Cs is restored to the original form by its own elastic force of said other hook a piece 10 (locking stepped portion 10a) is engaged with the said other lateral rods 2 _3, so that the engaged置係placing the concave portion 9a (fulcrum portion) of each Shu杆8,8 on Tate杆1 If the auxiliary carrier Cs is placed in a substantially horizontal state, the mounting operation is completed.
[0021]
Thus, in the attached state of the auxiliary carrier Cs, the auxiliary carrier main body 7 has a relationship in which the center of gravity of the carrier Cs is deviated outward from the vertical rod 1 even if no load is placed on the auxiliary carrier Cs. In this case, a moment around the concave bent portion 9a (fulcrum portion) that acts to turn the tip portion of the main body 7 overhanging from the carrier frame Cf downward (and hence the hook piece 10 upward) acts. The moment is received by the carrier frame Cf through the engaging portions of the hook piece 10 serving as the point of action and the horizontal rods 2 ₂ and 2 ₃ , so that the auxiliary carrier Cs can be maintained in a certain and proper installation posture. Is possible. In particular, when a load is placed on the auxiliary carrier Cs, since the weight of the load is added to the auxiliary carrier Cs, a moment in the same direction as that of the moment acts on the auxiliary carrier Cs. Support is more stable.
[0022]
The operation of removing the auxiliary carrier Cs from the carrier frame Cf may be performed in the reverse procedure.
[0023]
Thus, when attaching / detaching the auxiliary carrier Cs, the hook pieces 10, 10 can be elastically deformed to change the distance between the hook pieces 10, 10 connected to the pair of main rods 8, 8 of the auxiliary carrier body 7. 10 can be easily engaged with and disengaged from the carrier frame Cf (especially, the horizontal frames 2 ₂ and 2 ₃ as the second frame portion), so that the efficiency of attaching and detaching the auxiliary carrier Cs can be increased. Moreover, the engagement state between the hook pieces 10 and 10 and the carrier frame Cf (especially the horizontal ribs 2 ₂ and 2 ₃ as the second frame portion) is effectively maintained by utilizing the elastic restoring force of the auxiliary carrier Cs itself. Is possible.
[0024]
FIG. 6 shows a second embodiment of the present invention. In this embodiment, the basic shape of the auxiliary carrier body 7 is substantially U-shaped as in the previous embodiment. However, as an engagement piece connected to the base ends of the pair of front and rear main rods 8 and 8, respectively. The shape of the hook pieces 10 and 10 is different from that of the above embodiment, that is, the hook pieces 10 and 10 are formed outward so that their tips are separated from each other. Thus, even in this embodiment, the auxiliary carrier Cs is elastically deformed when the auxiliary carrier Cs is attached / detached. In particular, since the pair of hook pieces 10 and 10 as the engaging pieces are outward, this embodiment is performed. In the example, the pair of main rods 8 and 8 are elastically deformed so as to approach each other to reduce the mutual distance between the front and rear hook pieces 10 and 10. Other work procedures are the same as those in the above-described embodiment, and the same effects as those in the above-described embodiment can be expected.
[0025]
As mentioned above, although the Example of this invention was described, this invention is not limited to these Examples, A various Example is possible within the scope of the present invention. For example, the storage location of the auxiliary carrier when not in use is not limited to the tail bag on the carrier frame as shown in the illustrated example. For example, if the tail back is omitted, put the container in a suitable position on the vehicle body such as under the motorcycle seat. It may be installed and the auxiliary carrier may be accommodated therein, or the auxiliary carrier may be carried directly by the passenger in a bag or the like. In the illustrated example, the engagement piece serving hooks 10, 10 second, but so as to engage the horizontal rod 2 _2, 2 ₃ of the third row, the other transverse rod optionally 2,2 ₁ You may make it engage with.
[0026]
【The invention's effect】
As described above, according to the invention of each claim, since the auxiliary carrier can be attached to and detached from the carrier frame, the load carrying area of the carrier frame can be reduced as needed by attaching the auxiliary carrier to the carrier frame as necessary. Therefore, even if the carrier frame itself is relatively small, a large load can be loaded with the auxiliary carrier without difficulty. Moreover when the mounting of the auxiliary carrier, the main rod base of the auxiliary carrier body, together with the engaged置係mounting the fulcrum and the concave shape of the lower opening on the first frame portion of the carrier frame, of the main lever The base end engaging piece is engaged with the second frame portion of the carrier frame from below so as to restrict the rotation around the fulcrum portion of the main body against the moment caused by the weight of the auxiliary carrier main body , and a locking stepped portion formed on the engaging piece, because it is only Ru was immovably locked relative to the second frame portion in a direction along the first frame portion, or the handling operation is only a good The support structure for fixing the auxiliary carrier to the carrier frame is simple and can contribute to cost reduction. If the auxiliary carrier is not required, it can be separated from the carrier frame and stored in the car body compartment, etc., so there is no risk of damaging the appearance and improving the merchantability of the motorcycle. it can.
[0027]
In particular, according to the invention of claim 2, the auxiliary carrier main body is elastically deformed, and the pair of engagement pieces at the base end of the carrier main body is simply changed to change the engagement pieces to the carrier frame. Since the auxiliary carrier can be easily attached to and detached from the carrier frame, and the elastic restoring force of the auxiliary carrier itself can be used to connect the engagement piece and the carrier frame (second frame portion). Since the engaged state can be effectively maintained, the support of the auxiliary carrier is stabilized accordingly.
