FORM 2 THE PATENTS ACT, 1970 [39 OF 1970] THE PATENTS RULES, 2003 COMPLETE SPECIFICATION [See Section 10; rule 13] "AN IMPROVED HEAT SHIELDING PANEL ATTACHMENT STRUCTURE" HONDA GIKEN KOGYO KABUSHIKI KAISHA, a corporation of Japan, having a place of business at 1-1, Minamiaoyama 2-chome, Minato-ku, Tokyo, Japan, ORIGINAL 937/MUMNP/2000 GRANTED 20-5-2000 The following specification particularly describes the nature of the invention and the manner in which it is to be performed:- The present invention relates to an improved heat shielding panel attachment structure for attaching a cover member The . present invention also relates to a cover member attachment structure for reducing the number of parts through elimination of a welding step and so on. [Related arts] An example of cover members, which cover the respective sections of a vehicle, is a heat shielding panel to be attached to an exhaust pipe or a silencer, which communicates with an engine. Known examples of a heat shielding panel attachment structure include, for example, (1) "a motorcycle exhaust pipe device"., disclosed in Japanese Patent Publication No. Hei 2-26045, and (2) a structure for attaching a heat shielding panel to a bracket using a screw, the bracket being attached to an- exhaust pipe. (The art (1) discloses, as shown in Fig. 5 of the publication, an exhaust pipe device, in which the external circumferential surface of a single pipe 11 is clamped by a first band 161 which is attached to a heat shielding panel 15 via a spacing panel 17, and a second band 16,, which communicates with the first band 161, and the respective ends of the first band 161 and the second band 162 are attached, using a bolt 22 and a nut 23, to a positioning projected piece 24, projected from the external circumferential surface of the single pipe » 11, whereby the heat shielding panel 15 is attached to the single pipe 11. The above mentioned art (2) will be described referring to Fig. 8. Fig. 8 is a cross sectional view explaining a conventional cover member attachment structure, showing a state in which a bracket 102, having an inverted C-shaped cross section and a nut 101 welded on the inner surface thereof, is welded on the external circumferential surface of the exhaust pipe 103, and a screw 107 is inserted through an attachment hole 105, formed on a heat shielding panel 104, which serves as a cover member, and a piercing hole 106, formed on the bracket 102, and then screwed into the nut 101, whereby the exhaust pipe 103 is attached to the heat shielding panel 104. [Problems to be solved by the invention] According to the art (1), as the first band 161 and the spacing panel 17, and the spacing panel 17 and the heat shielding panel 15 are respectively welded, the heat shielding panel 15 and the first band 161 may possibly be distorted due to the heat caused during the welding process . Therefore, careful welding is required for minimizing the distortion. In addition, as a bolt 22 and a nut 23 are used for securing the first band 161 and the second band 162 to the single pipe 11, the number of parts is increased, resulting in a cost increase. As a result, distortion on the heat shielding panel, which would be caused when attaching a cover member through welding and so on, is not caused. In addition, a step of positioning a bracket, which would be required in welding a bracket to an object to be shielded, can be omitted. Further, as'no bolt and nut is used, the number of parts can be reduced. According to claim 2, the cover member is a member to be attached to a part of an intake and exhaust system, which communicates with an engine. When attaching, for example, an air cleaner case cover or a heat shielding panel as a cover member to a part of an intake and exhaust system, a spring member is used. As a result, for an air cleaner case cover, for example, vibration can be efficiently suppressed by means of elastic force of the spring member. For a heat shielding panel, when a spring member is made detachable, should the spring member be worn out due to heat, the spring member can be easily exchanged. The present invention relates to an improved heat shielding panel attachment structure for attaching a cover member to an object to be shielded for the purpose of improving appearance, suppressing heat propagation, preventing solid or liquid scattering, preventing invasion to or leakage from the inside, comprising: at least three spring members for elastically attaching the cover member to the object to be shielded and suppressing vibration between the cover member and the object to be shielded, wherein the cover member has at least a first section, a second section, and a third section formed separately from each other, the sections being attached by the spring members serially along a length of the object to be shielded.

Note that the drawings are observed in the direction of the reference numerals. Fig. 1 is a perspective view showing an all-terrain vehicle employing a cover member attachment structure of the present invention. An al-terrain vehicle 10 comprises a handle rotatably attached to a vehicle body frame (not shown), front wheels 12, 12 steerably connected to the handle 11 via a steering mechanism (not shown) and vertically movably attached to the vehicle body frame via an arm (not shown) , a seat 13 attached above the vehicle body frame, and a power unit 16 including an engine 14 attached below the seat 13, and a transmission 15, an exhaust pipe 17 extending from the front side of the engine 14 forward and then backward, a silencer 18 attached to the trailing part of the exhaust pipe 17, and rear wheels 21, 21 (reference numeral farther from the reader being not shown) for being driven, together with the front wheels 12, 12, via a driving power » transmission mechanism (not shown) by the power unit 16. Note that 23 is a front carrier, 24 is a front bumper, 25 is a front fender, 26 is a head lamp, 27 is a rear career, and 28 is a rear fender. The above mentioned exhaust pipe 17 as an object to be shielded, a silencer 18 as an object.to be shielded, and heat shielding panels as cover members (described later) attached to the exhaust pipe 17 and the silencer 18 together constitute an exhaust device 30. An.all- terrain vehicle (ATV, all terrain vehicle) 10, including, for example, a buggy, can turn in a small space and be easily operated due to its light and compact vehicle body, and is an off-road vehicle suitable for use in moving in agriculture, cattle breeding, hunting, safeguarding, leisure, and so on. Fig. 2 is an exploded perspective view showing an exhaust device having a cover member attachment structure of the present invention. The exhaust device 30 comprises an exhaust pipe 17 including a front exhaust pipe 31 having a J shape to be attached on the engine side, and a rear exhaust pipe 32 connected to the trailing part of the front exhaust pipe 31, a silencer 18 connected to the rear exhaust pipe 32, a front heat shielding panel 33 for preventing heat propagation to the side of the front exhaust, pipe 31, a rear heat shielding panel 34 for preventing heat propagation to the side of the rear exhaust pipe 32, small set springs 35 as spring members for attaching the front and rear heat shielding panels 33, 34 to the front and rear exhaust pipes 31, 32, respectively, a silencer heat shielding panel 36 for preventing heat propagation to the side of the silencer 18, and large set springs 37, 37 as spring members for attaching the silencer heat shielding panel 36 to the silencer 18. The silencer 18 has vehicle body attaching parts 41, 41 for attachment to the vehicle body frame (not shown). the rear exhaust pipe 32 has projections 42, 42 formed on • the sides of the front and trailing ends thereof, respectively. The front heat shielding panel 33 is formed by halving in the longitudinal direction a cylinder having a larger inner diameter than the outer diameter of the front exhaust pipe 31, bending the halved cylinder along the shape of the side of the front exhaust pipe 31, and forming clamped parts 43, 43 at the both ends of the cylinder for abutting on the external circumferential surface of the front exhaust ,pipe 31. The rear heat shielding panel 34 is formed by halving in the longitudinal direction a cylinder having a larger inner diameter than the outer diameter of the rear exhaust pipe 32, bending the halved cylinder along the shape of the side of the rear exhaust pipe 32, forming clamped parts 44, 44 at the two ends of the cylinder for abutting on the external circumferential surface of the rear exhaust pipe 32, and forming positioning holes 45, 45 on the clamped parts 44, 44 to receive the projections 42, 42 of the rear exhaust pipe 32. With the projections 42, 42 fitting to the positioning holes 45, 45, the rear heat shielding panel 34 is prevented from moving in the circumferential and longitudinal direction of the rear exhaust pipe 32. A small set spring 35 is a spring member formed by bending a panel so as to have a cross sectional view of a substantial Q shape, for elastically clamping the front exhaust pipe 31 via the clamped parts 43, 43 of the front heat shielding panel 33 to thereby attach the front heat shielding panel 33 to the front exhaust pipe 31, and for elastically clamping the rear exhaust pipe 32 via the clamped parts 44, 44 of the rear heat shielding, panel 34 to thereby attach the rear heat shielding panel 34 to the rear exhaust pipe 32. The silencer heat shielding panel 36 is formed by halving in the longitudinal direction a cylinder having a larger inner diameter than the outer diameter of the silencer 18, forming clamped parts 46, 46 at the middle parts thereof in the longitudinal direction, for abutting on the external circumferential surface of the silencer 18, and forming notches 47, 48 for preventing interference with the vehicle body attaching parts 41, 41 of the silencer 18. A large set spring 37 is a spring member formed by bending a panel, into a substantially key-hole shape when viewed from the side, having a structure' in which a screw piercing hole 51 is formed and a nut 52 is fixed on one end thereof, the other end thereof is worn out so as to form a return part 53, where a screw piercing hole 54 is formed, and a screw 55 is inserted through the two screw piercing holes 51, 54 and then screwed into the nut 52. A large set spring 37 is a member for elastically clamping the silencer 18 via the clamped parts 46, 46 of the silencer heat shielding panel 36 and for further clamping the silencer 18 by using a screw whereby the silencer heat shielding panel 36 is attached to the silencer 18. In the front exhaust pipe 31 described above, the front neat shielding panel 33 does not move in the circumferential or longitudinal direction with respect to the front exhaust pipe 31 as the clamped parts 43, 43 of the front heat shielding panel 33 are clamped for attachment from different directions (front and sides) by the small set springs 35, 35. However, in the rear exhaust pipe 32, as the clamped parts 44, 44 of the rear beat shielding panel 34 are clamped for attachment from substantially the same direction (the side) by the small set springs 35, 35, with this only, the rear heat shielding panel 34 may move with respect to the rear exhaust pipe 32 due to vibration. The position of the rear heat shielding panel 34 with respect to the rear exhaust pipe 32 is determined such that the projections 42, 42 of the rear exhaust pipe 32 and the positioning holes 45, 45 of the rear heat shielding panel 34 are fitted to each other. Fig. 3 is a perspective view showing an exhaust device having a cover member attachment structure of the present invention, showing a state in which the front heat shielding panel 33 and the rear heat shielding panel 34 are attached to the front exhaust pipe 31 and the rear exhaust pipe 32, respectively, by using the small set springs 35, and the silencer heat shielding panel 36 is attached to the silencer 18 by using the large set springs 37, 37. Fig. 4 is a cross sectional view of Fig. 3 along the line 4-4, showing a state in which the clamped part 44 of the rear heat shielding panel 34, which is formed in a shape similar to that of the external circumferential surface of the rear exhaust pipe 32, is placed on the external circumferential surface of the.rear exhaust pipe 32 such that the projections 42 of the rear exhaust pipe 32 are fitted to the respective positioning holes 45 of the rear heat shielding panel 34, and the clamped parts 44 are pressed onto the rear exhaust pipe 32 by means of the reduced elastic force applied by the small set spring 35. Note that SI is a step difference between the clamped part 44 and the remaining part, or a part excluding the clamped part 44, of the rear heat shielding panel 34, CI is a distance between the external circumferential surface of the rear exhaust pipe 32 and the inner surface of the part excluding the clamped part 44 of the rear heat shielding panel 34, i.e., the maximum clearance between the rear exhaust pipe 32 and the rear heat shielding panel 34. A small set spring 35 comprises, in detail, a large C-shaped arc section 61 and small C-shaped arc sections 62, 62, each being continuous to each end of the large arc section 61. With the space between the small arc sections 62, 62 being used as an opening, the opening can be smoothly widened so that the small set spring 35 can be easily fitted onto the clamped part 44 of the rear heat shielding panel 34. A small set spring 35 is used with respect to the rear exhaust pipe 32 having a smaller diameter, as described above, because a small set spring 33 having a smaller diameter can generate a relatively large elastic force, i.e., a spring with a relatively large spring constant can be manufactured. By using a spring with a relatively large spring constant, the rear heat shielding panel 34 can be secured to the rear exhaust pipe 32 by a sufficient elastic force caused by only the small set spring 35. The cross section of the front exhaust pipe 31, the front » heat shielding panel 33, and the small set spring 35 being assembled together, as shown in (Tig. 3, is identical to that which is shown in Fig. 4, except for the projection 42 and the positioning hole 4 5, and the explanation thereof Is omitted. Fig. 5 is a cross sectional view of Fig. 3 along the line 5-5, showing a state in which the clamped part; 42 of the silencer heat shielding panel 36, which is formed so as to have a shape similar to that of the external circumferential .surface of the silencer 18, is placed on the external circumferential surface of the silence? 18, and the allencer. heat shi-lding panel 36 is attached to the silancer 18 by ceduced. Lastic force applied by the large ser spring 37 and the engaging force applied by the sorew 55 and the. nut 52. Note that is a step difference between the clampod part the of the, silerncer hear shielding panel 36 and a part excluding th A large set spring 37 comprises, in detail, a large C-shaped arc section 64, a return section 53, and a bending section 65, the return section 64 and the bending section 53 both being continuous to the respective ends of the large arc section 64, in which a screw piercing hole 54 (see Fig. 2) is formed piercing through the two panels of the return section 53, a screw piercing hole 51 (see Fig. 2) is formed and a nut 52 is secured on the bending section 65. A large set spring 37 of a large diameter having a nut > 52 is used with respect to the silencer 18 of a large diameter, as described above, because it is difficult for a large set spring 37 having a large diameter to cause a large elastic force. That is, it is difficult to manufacture a spring with a large spring constant. In order to compensate the elastic force, engagement between the screw 55 and the nut 52 is utilized. With the elastic force by the spring and the engaging force by the screw and the nut, the silencer heat shielding panel 36 can be secured to the silencer 18 with sufficient force. As described above with reference to Figs. 4 and 5, the present invention is characterized by a cover member attachment structure for attaching heat shielding panels 33, 34, 36 as cover members for the purpose of improving appearance,, suppressing heat propagation, preventing solid or liquid scattering, preventing invasion to or leakage from the inside, and so on, in which the heat shielding panels 33, 34, 36 are attached to the exhaust pipes 31, 32, and the silencer 18 as objects to be shielded, by using small set springs 35 and large set springs 37. With the above structure, distortion on a heat shielding panel, which would be caused when attaching a heat shielding panel through welding and so on, is not caused. In addition, a step of positioning a bracket, which would be required in welding a bracket to an exhaust pipe, can be omitted. As a result, productivity can be improved. Further, as no bolt and nut is used when attaching the front and rear heat shielding panels 33, 34 to the front and rear exhaust pipes 31, 32, the number of parts can be reduced, whereby cost increase can be suppressed. » Also, the present invention is characterized by the fact that a cover member is a member to be attached to a part of an intake and exhaust system, which communicates with an engine 14. For attaching, for example, an air cleaner case cover (not shown) or heat shielding panels 33, 34, 36 as cover members to a part of an intake and exhaust system, a small set spring 35 and a large set spring 37 are used. With the above structure, for an air cleaner case cover, for example, vibration can be efficiently suppressed by means of elastic force of the spring member. For the heat shielding panels 33, 34, 36, when a small set spring 35 and a large set spring 37 are made detachable, should the small set spring 35 and the large set spring 37 be worn out due to heat, the small set spring 35 and the large set spring 37 can be easily exchanged. Operation of a small set spring 35 described above will next be described. Figs. 6(a) to 6(b) are diagrams explaining operation of a small set spring according to the present invention. Operation of a small set spring according to the present invention will be described, as well as a manner of attaching the rear heat shielding panel 34 to the rear exhaust pipe 32. To attach the rear heat shielding panel 34 to the rear exhaust pipe 32, in Fig. 6(a), the projection 42 of the rear exhaust pipe 32 is fitted to the positioning hole 45 of the rear heat shielding panel 34, and the clamped part 44 of the rear heat shielding panel 34 is placed on the external circumferential surface of the rear exhaust pipe 32. In Fig. 6(b), the opening of the small set spring 35 is pressed onto the rear heat shielding panel 34, and, as shown in Fig. 6(c), the small set spring 35 is pressed onto the rear heat shielding panel 34 to thereby widen the opening of the small set spring 35. Then, as shown in Fig. 6(d) , the small set spring 35 is fitted onto the rear exhaust pipe 32 via the rear heat shielding panel 34. At this time, the small set spring 35 applies an inward elastic force, as represented by the arrows Fl, F2 in the drawing, to the rear exhaust pipe 32 and the clamped part 44, and an inward elastic force, as indicated by the arrows F3, F4, only to the rear exhaust pipe 32. The elastic forces Fl, F2 are forces pressing the clamped part 44 onto the rear exhaust pipe 32. With the elastic forces Fl, F2, the clamped part 44 can be reliably stuck to and fixed on the rear exhaust pipe 32. With the elastic forces F3, F4, the rear heat shielding panel 34 can be prevented from being displaced sideways. To remove the rear heat shielding panel 34 from the rear exhaust pipe 32, the above mentioned procedure may be followed in reverse. Then, as it is possible to remove the small set spring 35 by simply widening the opening thereof, removal of the small set spring 35, as well as attachment thereof, can be easily achieved. Therefore, the rear heat shielding panel 34 can be easily exchanged. Fig. 7(a) to 7(e) are diagrams explaining operation of a large set spring according to the present invention. Operation of a large set spring according to the present invention will be described as well as the manner of attaching the silencer heat shielding panel 36 to the silencer 18. To attach the silencer heat shielding panel 36 to the silencer 18, in Fig. 7(a), the clamped part 46 of the silencer heat shielding panel 36 is placed on the external circumferential surface of the silencer 18. As shown in Fig. 7 (b) , the opening of the large set spring 37 is pressed onto the silencer 18, and, as shown in Fig. 7(c), the large set spring 37 is further pressed onto the silencer 18 to thereby widen the opening of the large set spring 37 . Then, as shown in Fig. 7(d), the large set spring 37 is fitted onto the silencer 18 via the clamped part 46, and the screw 55 is inserted through the screw piercing holes 51, 54, and, as shown in Fig. 7(e), screwed into the nut 52. Then, the large set spring 37 applies an inward elastic force, represented by the arrows F5, F6, to the silencer 18 and the clamped part 46,. and an inward elastic force, indicated by the arrows F7, F8, only to the silencer 18. The elastic forces F5, F6 are forces pressing the clamped part 4 6 onto the silencer 18. With the elastic forces F5, F6, the clamped part 46 can be reliably stuck to and fixed on the silencer 18. With the elastic forces F7, F8, the silencer heat shielding panel 36 can be prevented from being displaced sideways. As described above, with the elastic force by the large set spring 37 and the engaging force by the screw 55 and the nut 52, the silencer heat shielding panel 36 can be rigidly attached to the silencer 18. To remove the silencer heat shielding panel 36. from the silencer 18, the above procedure may be followed in reverse. Note that a spring member of the present invention is not limited to a panel type, as described in the embodiment, and may be a wire type. Also note that a cover member of the present invention is not only a heat shielding panel as a cover member of an exhaust system and an air cleaner case cover to be attached to an air cleaner case of an intake system, but may also be, for example, in motorcycles, a front fender to be attached to a front fork, a front fork cover, a chain cover to be attached to a rear fork, a cover to be attached to a passenger's handle provided behind a seat, and a handle cover to be attached to a handle. Further, although heat shielding panels are attached to both of an exhaust pipe and a silencer in the above embodiment, this is not an exclusive example. That is, a heat shielding panel may be attached to at least one of the exhaust pipe and the silencer or to at least one of the front exhaust pipe and the rear exhaust pipe. [Advantage of the invention] The present invention having the above structure can produce the. following advantage. According to a cover member attachment structure of claim 1, as a cover member is attached to an object to be shielded, by using a spring member, distortion on a cover member, which would be caused when attaching a cover member through welding and so on, is not caused. In addition, a step of positioning a bracket, which would be required in welding a bracket to an object to be shielded, can be omitted. Further, as no bolt and nut is used, the number of parts can be reduced. According to a cover member attachment structure of claim 2, a cover member is a member to be attached to a part of an intake and exhaust system, which communicates with an engine. Thus, for an air cleaner cover, for example, vibration can be efficiently suppressed by means of the elastic force of the spring member, and, for a heat shielding panel, when the spring member is made detachable, should the spring member become worn out due to heat, the spring member can be exchanged.
