And a reinforcing member 68 is formed. 6 9 is an annular portion attached to the front portion of the frame 6 6 R, and 80 is an engaging member attached to the frame 66R. The details thereof will be described later. -13- (10) 1247706 Fig. 4 is a side view of the shelf of the present invention (the handle locking mechanism 'the structure of the full cap holder is not shown), and the rear leg 6 5 with respect to the front leg - 6 4 R L, 6 5 R is shortened, and the cargo placing portion 61 is horizontally leveled, and the frames 66L and 66R are inclined obliquely rearward and upward. Other parts The drawing numbers of Fig. 3 are omitted for detailed description of each element. Fig. 5 is a sectional view taken along line 5-5 of Fig. 4, the shank type clamp ^ is composed of a bird-shaped branch φ 7 1 which is erected on the arc-shaped cross-sectional frame 6 6 L and penetrates through the support member 71 The lower lower pin 7 2, the triangular rocking member 73 of the lower pin 72, the shank 74 fixed to the member 73, the upper portion 75 penetrating the upper portion of the swinging member 73, and the The upper pin 7 5 is formed by a downwardly extending j-shaped member 7 6 . Between the arc-shaped cross-sectional frame 660L and the rail straight portion 5L, a cushioning member 660a made of rubber is used. A stopper 6 6 b is attached to the face frame 6 6 L, and the stopper 6 6 b is used to restrict the setting of the j-shaped member 76. Fig. 6 is a sectional view taken along line 6-6 of Fig. 4, showing the upper member 75 for rotatably holding the J-shaped members 76, 76. Fig. 7 is a sectional view taken along line 7-7 of Fig. 4, showing that the lower pin 7 2 freely rotates the rocking member 713 and the shank portion 7 in the support member 71. • Fig. 8 is the action diagram of Fig. 5. When the shank 7 4 is lifted up and the lower pin 7 2 is centered, the upper pin 7 5 is rotated, and the initial position doubles as An 64L, and the position is slightly used. The bearing member is mounted on the swinging square pin. • 76 has an arc-shaped lower limit position: when mounted on the pendulum = through the ground, it is lowered by -14-(11) 1247706. As a result, the J-shaped members 76, 76 are detached from the guide rail line 51L on the side of the armrest bar. Once the detachment is made, the J-shaped members 76 and 76 are placed at the position indicated by the imaginary line, so that the detachment from the guide rail straight portion 5 1 L is completely provided on the upper stopper portion of the support member 71. With this upper stop 77, the fully open position of the handle 74 can be determined. When the shank portion 74 is lowered, it is obvious that the J-shaped members 76, 76 are engaged with the guide straight portion 5 1 L, and the state thereof is the figure number 7 in Fig. 5 as shown in Fig. 5. It is a lower stopper portion, and 7 8 a is a cushioning member made of rubber covering the lower stopper 78, and the lower stopper portion 74 can define the completely closed position of the shank portion 74. Fig. 9 is a view showing a mounting point of the rack of the present invention, and 86 and 86 are plug portions, which are fitted to the front end openings of the rail straight portions 5 1 L and 5 1 R to improve the appearance and prevent foreign matter from entering. Go to the grab bar 50. When the person does not ride on the rear occupant seat cushion 26 and needs to mount the shelf 60, the shelf 60 can be attached to the handrail bar in the following order. In this case, as described below, the rack can be mounted without using a tool. That is, first, in a state in which the length of the annular portion 619 is shifted forward, the shelf 60 is placed on the handrail lever 60, and in detail, the frame 66L is placed on the guide rail straight portion 51L of the handrail lever, The frame 66R is placed on the rail straight portion 5 1 R of the handrail bar. Next, the entire shelf 60 is slid rearward. Then, the round portion can be moved away from the rail portion to cover the 50 cargo portion, and the carrier ring -15-(12) 1247706 portion 6 9 is fitted to the front portion of the rail straight portion 5 1 R. In the action\personal treatment, the engaging member 80 does not collide to the front 57. The first figure is the rear of the body after the shelf is installed. The rear part of the driver's seat cushion 25 is installed with a wide portion 6 The shelf 60 of 1 can improve the handling of goods. Fig. 1 is a rear side of the vehicle body after the rack is mounted | Adjusting the length of the front legs 64L, 64R and the rear legs 65L, 'so that it can be on the lower surface of the cargo mounting portion 61 and the upper surface of the rear mat 26 Make sure there is a gap d. By ensuring that the gap is worried that the shelf 60 is in contact with the rear occupant's seat cushion 26, the rear occupant's seat cushion 26 can be sufficiently extended to make the rear end of the shelf 60 and the handrail In the manner in which the rod 50 has a gap L1 behind it, the total length L2 of the rack 60 is shortened to reduce the size of the rack 60. However, this miniaturized structure is prone to problems when carrying a substance. As a countermeasure, as shown by the horizontal line h, the upper surface of the shelf is made substantially conform to the upper surface portion of the cargo placing portion 61. The larger cargo 8 8 shown by the imaginary line can mount the upper surface of the rear end of the 邰 邰 6 1 and the grab bar 50. Therefore, the length of the placing portion 61 is shortened, and the cargo performance is not lowered. Next, the engaging member of the present invention will be described in detail. Figure 12 is a cross-sectional view of the main part of Fig. 2, (a is a line sectional view, (b) is a line b sectional view, (c) is a period, is a view of the rear stopper member, due to the cargo mounting surface view With the length of the 6 5 R occupant seat d, it does not have to be damaged. The end of life is used. The end is opened. As a result, the rear end of the larger cargo can be placed to cover the cargo even if the cargo is the first 2 Figure c line cross-sectional view -16 (13) 1247706, (d) is a d-line cross-sectional view. In the figure (a), since the engaging member 80 is engaged (refer to the first) to the front and rear stopper members 5, it is not necessary to worry that the frame 66r is displaced toward the front and back directions. 8 3 is a closing action restricting stopper which is formed on the side of the upper side such as the rear arm portion 54R. Its role will be described later. In the figure (b), reference numeral 84 denotes an opening position restricting stopper which is, for example, a sheet portion fixed to the lower surface portion of the front arm portion 53R on the side of the fixed lever. 6 6 R can be rotated by about 90° in the counterclockwise direction, so that the front end of the frame 6 6 R abuts against the open position limit stop 84. In the figure (c), since the annular portion 69 is straight around the guide rail 5 1 R, even if the frame 6 6 R is rotated, there is no fear of being detached from the guide portion 5 1 R. In the diagram (d), a semi-annular portion 85 is attached to the frame 66R, and the semi-annular portion 85 is in contact with the rail straight portion 5 1 R. Figure 13 is an action diagram of Figure 12. (a) The figure shows that the rear 65R is rotated along the straight line portion 5 1 R of the guide rail as indicated by the arrow with the opening operation of the shelf. Since the engaging member 80 has ample space, it does not hinder the rotation of the foot 6 5 R. However, the process of moving the engaging member 80 from the right to the left of the drawing will pass the closing action restricting block 83. In the figure (b), since the end 66 6 a of the frame 6 6 R is abutting the position restricting stopper 84 ′, the frame 66R does not turn further left. In the figure (c), since the ring portion 6 9 surrounds the guide rail, the hand lever is straight in the line of the frame 66a, and the leg is pinched to the rear side toward the open side rotation portion -17- (14) 1247706 5 1 R, so even if the frame 6 6 R is rotated, there is no fear of being detached from the straight line portion 5 1 R of the guide rail. (d) The semi-annular portion 8 5 in the figure functions to smoothly rotate the frame 66 6 r together with the annular portion 6 9 in the figure (c). Figures 1 2 to 1 3 are diagrams showing the essentials for opening the shelf. It is a little different from the essentials when closing the shelves. That is to say, in Fig. 13(a), when the shelf is to be closed, the rear leg 6 5 R is rotated by g in the clockwise direction of the figure, so that the front end of the engaging member 80 abuts against the closing action limit stop. 8 3, and can not carry out further closing action. This is a unique effect of the present invention in order to not let the shelf close without care. The restriction of the closing operation by the closing operation restriction block 83 can be released in the order of the following drawings. Fig. 14 is a view showing the operation of the closing operation restricting stopper of the present invention. In order to avoid or cancel the engagement member 80 as shown in (a), the engagement member 80 abuts the closing operation restricting stopper 83, such as ( b) It is sufficient to lift the engaging member 80 by a finger as shown in the figure. By this, the rack can be closed as shown in (c). This (c) diagram is the same as that of Fig. 2 (a). When the shelf is closed, as shown in Fig. 2, the elastic member 81 will act as a buffer, and the closing action will be stable. Next, the shank locking mechanism provided in the vicinity of the shank clamp 7 所示 shown in Fig. 9 also serves as the helmet holding member 90. Fig. 15 is an explanatory view showing the shank locking mechanism of the present invention as a helmet retaining member, and the shank locking mechanism also serves as a helmet retaining member 90, which is composed of: a keyhole -18-(15) 1247706 9 1 and a locking pin The seat main body 93 of 92 and the locking hole 94 opened in the handle 74 are comprised. Fig. 16 is a view showing the action of the shank locking mechanism of the present invention as a helmet retaining member. The locking pin 92 is inserted into the ring portion 96 provided at the front end of the cap of the helmet 95, and is inserted into the locking hole 94. In this case, the helmet 95 can be held by the handle locking mechanism as the helmet holder 90. Fig. 17 is an explanatory view of the handle locking of the present invention as an explanatory view of the second stopper, showing that the locking pin 92 is inserted through the shank portion 74 to lock the shank portion 74 so as not to swing. situation. When the handle portion 74 is brought into a locked state, the shelf 60 can be surely engaged with the handrail bar 50 without fear that the shelf 60 will fall off. On the rear side of the frame 66L on the left side, a second stopper 97 extending downward is provided, and a cushion member 97a made of rubber is covered on the second stopper 97. The second stopper 97 is disposed at a position facing the rear arm portion 54L of the handrail lever 50. Fig. 18 is a view showing the action of the second stopper, so that the second stopper 9 7 is engaged with the rear arm portion 54L. As a result, there is no need to worry about the case where the left frame 66L is shifted toward the front (left side). In other words, the left and right stoppers formed by the second stopper 97 and the front and rear stopper members 57 shown in Fig. 2 can surely prevent the i-frame from moving toward the square. The structure of the first invention is mainly as shown in Fig. 1. By removing the shelf 60, the person can ride on the seat cushion for the rear passenger seat at any time (Fig. 26 of Fig. 1). By removing the shelf 60, -19-(16) 1247706 can improve the appearance of the rear of the vehicle body. • The second invention is mainly shown in Figs. 3 and 11. Fig. 3 is a view showing that the left and right leg members 63 L and 63R are extended downward from the substantially flat cargo placing portion 61. In Fig. 1, the foot members 63 L and 63 R are attached to the armrest. The rod 50 sets the length of the leg member so that the gap d 〇g can be secured between the lower portion of the cargo placing portion 61 and the rear occupant seat cushion 6 6 because it can be placed in the cargo loading portion 6 1 A gap d is ensured between the lower portion of the lower portion and the rear occupant seat cushion 26, so that the shelf 60 does not contact the rear occupant seat cushion 26, and the service life of the rear occupant seat cushion 26 can be extended. The structure of the third invention is mainly shown in Fig. 9. That is, by rotatably attaching one of the left and right foot members (the right foot member 6 3 R side) to the handrail bar 50, the other leg member is, for example, the shank clamp 70 (the left leg member 63L side) is lockably attached to the grab bar 50. When the rotating shelf 60 is opened, the seat cushion 25 is opened to enable refueling of the fuel tank 28 under the seat cushion shown in Fig. 1 or for the storage portion under the seat cushion. Take it in and take it out. The structure of the fourth invention is mainly such that, as shown in Fig. 1, the gap L 1 is opened so that the rear end of the shelf 60 is set to be forward of the rear end of the handrail lever 50. Therefore, the shelf 60 is inevitably shortened, so that the rack 60 can be miniaturized. The structure of the fifth invention, mainly as shown in Fig. 1, is the rear end of the shelf 60 -20 - (17) 1247706. That is, the rear end of the cargo load 邰 6 1 and the handrail lever 5 〇 - ' The alignment is made at substantially the same height as the horizontal line h. As a result, as shown in Fig. 1, the large cargo 8 8 can be supported by the cargo loading portion 60 and the rear end of the handrail bar 5 。. The structure of the invention of the table 6 is mainly as shown in Fig. 9, in which the annular member 69 is attached to the leg member 63R, and the annular portion 6 9 is fitted to the armrest so as to be rotatable and detachable from the row. B of the rod 5 ( (the front end portion of the rail straight portion 5 1 R). The shelf 6 G can be attached to the shackle by sliding from the front to the back and can be removed by sliding it from the back toward the front. Thus, the shelf is easily detached or mounted from the grab bar 50. According to the structure of the seventh aspect of the invention, mainly as shown in Fig. 2, the front and rear stopper members 57 are engaged with the front and rear stopper members 57, and the member members are provided on one of the foot members (the frame on the right) By engaging the engaging member 80 with the front and rear stopper portions 57, the front and rear of the shelf can be moved. The structure of the eighth invention is mainly as shown in Fig. 2, and the engaging structure is formed: The direction of the surface is swingably disposed on one of the members (the frame 6 6 R on the right side), and the cushioning property can be exerted when the elastic member 8 is closed. The structure and function of the invention of the table 9 are mainly shown in the 14th When the shelf is closed to the middle, the engaging member 80 will be touched. The closing action of the closing action of the frame is limited to the stopper 83, and is disposed at the rear arm portion 5 4 R. As shown in (b) The rear end of the engaging member 80 is lifted, such as the front side of the second side, the front end 咅B three rods 5 0 60 can be set on the side of the lever 66R) to limit the middle 80, the square foot 1 to the cargo map. Yes Limit the side of the rod. -21 - (18) 1247706 In addition to the restriction of the closing action, the rack can be closed as shown in (c). Therefore, even if the shelf is closed without knowing that there is foreign matter on the grab bar, the shelf will stop once before the shutter is completely closed. When the shutter is released, the foreign matter can be found, so that the hinge can be prevented from being damaged. The structure of the first invention, as shown in Fig. 13 (b), is a handrail lever (front wrist portion 5 3 R) corresponding to one of the foot members, and is provided with: a full opening position for restricting the shelf The open position limits the stop 84. By providing the open position restricting stopper 84, the opening and closing stroke of the rack can be appropriately determined. The structure of the first aspect of the invention is mainly as shown in Fig. 9, that is, the other leg member 63L is provided with the shank type jaw portion 70, and the other side of the shank type jaw portion 70 can be used. The leg members 6 3 L are freely engageable and disengaged to engage with the handrail bars (the rail straight portions 5 1 L ). When the other leg member 633L is fixed to the handlebar 50 by bolts or small screws, it takes time to remove the bolt or the small screw. And since the handle type grip portion 70 is used in the first invention, the other leg member 6 3 L can be engaged and disengaged from the grab bar 50 as long as the handle portion 74 is operated, so that the engagement can be made. The breakaway time is shortened. The structure of the first invention is mainly shown in Fig. 3. That is, the 'side of the shank grip portion 70' is provided with a shank lock mechanism 90 that prevents the shank portion 74 of the shank grip portion from swinging. The structure of the first invention is as shown in Fig. 16. The handle lock mechanism 9 is also used as a helmet holder. If you use the hard hat holder that is often provided in the locomotive to lock the -22 - (19) 1247706 of the handle, the number of parts can be reduced due to the sharing of the mechanism. In the first invention, the shelf can also be attached and detached from the handrail bar, and the engagement configuration is not limited to this embodiment. The first invention may be provided with a helmet holder and a handle locking mechanism, respectively.
