Description

[Detailed Description of Device] a. Purpose of the invention (industrial application field) The present invention is a finisher mounting means for an exhaust pipe. More specifically, the present invention relates to a mounting means that makes it possible to securely and securely attach a finisher without dropping the finisher, because a holding member holds the exhaust pipe by a spring when the finisher is fitted into the exhaust pipe.

(Prior Art) Conventionally, a finisher double formed by an inner cylinder and an outer cylinder is used to swell four exhaust pipe holding portions inside the inner cylinder, and the exhaust pipe is held by these holding portions to exhaust the exhaust gas. A device for attaching a finisher to a pipe is known from Japanese Utility Model Application Laid-Open No. Sho 64-13223.

(Problems to be solved by the invention) However, when the holding portion is bulged from the inner cylinder of the finisher as described above, the spring action cannot be obtained because both ends of the holding portion are connected to the inner cylinder. Therefore, if the degree of fitting between the holding part and the exhaust pipe is set to the extent that the fitting and removal of the finisher are easy, the finisher is likely to fall off. There is a problem.

The present invention was made in order to solve the above-mentioned conventional problems, and by installing a holding member inside the finisher so that the spring works by the free portion, the finisher can be securely attached without falling off. Provide a means for attaching an exhaust pipe finisher, which is easy to put on and take off and looks good.

B. Configuration of the Invention (Means for Solving the Problems) In order to solve the above problems, a finisher mounting means for an exhaust pipe according to the present invention is provided with a fixing portion that is in close contact with the finisher, and is connected to the fixing portion so that the middle portion is curved. And a loosened part which is separated from the finisher so that the slab is effective, and a holding member for the exhaust pipe, in which a vertical convex bulge that contacts the exhaust pipe is bulged inside the loosened part, is placed inside the finisher In this structure, two sets are correspondingly fixed by the fixing portion, and the clamping member clamps the spring-loaded exhaust pipe.

The finisher in this mounting means is mounted on the outside of the end portion of a known exhaust pipe, and has a cross-sectional area larger than that of the exhaust pipe in order to allow an appropriate distance from the exhaust pipe. Is the same as the exhaust pipe, or is a square, polygon, or other irregular shape, and the material used is stainless steel, plated finish steel plate, etc. that does not damage the appearance due to rust or discoloration.

The exhaust pipe holding member to be attached to the inside of the exhaust pipe is formed by pressing a square steel plate, and is composed of a fixed portion that is in close contact with the inner circumference of the finisher and a loose portion that is continuous with this fixed portion. The loose part is separated from the finisher by bending etc. so that the spring works.The inside of the loose part is provided with a vertical ridge that contacts the exhaust pipe, and the part of the vertical ridge that contacts the exhaust pipe is uneven. It is desirable to take measures to increase the friction of the above, and it is convenient for manufacturing and assembling that the pair of free portions are connected by the fixed portion.

(Operation) The exhaust pipe finisher mounting means according to the present invention is formed by press-molding the holding member of the exhaust pipe so that the pair of free portions are connected by the fixed portion as shown in FIG. Spot welding is performed correspondingly to the inner circumference of the finisher by the fixing part. Then, four vertical ridges are lined up at a predetermined interval inside the finisher, so when the finisher is fitted to the end of the exhaust pipe as shown in Fig. 5, each vertical ridge is exhausted by the flexure of the loose part. Since it fits easily into the exhaust pipe by sliding around the peripheral surface of the pipe, if the finisher is stopped when the desired position is reached, the bent free part is reduced by the spring action and the exhaust pipe is clamped by each vertical ridge. Since the state is maintained by the spring action, the finisher is securely attached to the exhaust pipe without detaching it, it can be easily removed from the exhaust pipe by pulling on the finisher, and because it is an internal installation, it looks great. It's good.

(Embodiment) An embodiment of a finisher mounting means for an exhaust pipe according to the present invention will be described below with reference to the drawings.

In FIGS. 1 to 5, reference numeral 1 denotes a finisher, which is attached to the end of the exhaust pipe 2 of a known vehicle engine, so that it is a stainless steel plate that does not rust or discolor, a plated steel plate, etc. Is used to form a larger cross-sectional area than the exhaust pipe 1.

In FIGS. 1 to 5, reference numeral 3 denotes a holding member of the exhaust pipe 2, which is obtained by stamping a hard steel plate into a square shape by a press and then drawing it by the press to form a center portion as shown in FIG. Has a fixed portion a that is in close contact with the finisher 1, and the free portions b and b that are separated from the finisher 1 by bending or bending are continuously provided on both sides of the fixed portion a. The ridges 4 and 4 of the vertical ridges 4 and 4 are provided so as to be inclined at the start end side, and a plurality of protrusions 5 and 5 are provided at predetermined intervals at the portions of the vertical ridges 4 and 4 that come into contact with the exhaust pipe 2, As shown in FIG. 2, the pair of members 3 are fixed to the inside of the finisher 1 by spot welding or the like by the fixing portion a.
Then, in some cases, the finisher 1 in which the four vertical projections 4 contacting the exhaust pipe 2 are present in parallel at a predetermined interval is formed inside.

When the finisher 1 of this embodiment is fitted into the exhaust pipe 2 as shown in FIG. 5, the vertical protrusions 4 of the holding member 3 are slid on the peripheral surface of the exhaust pipe 2 because the free portions b are bent by the spring action. Then, when the finisher is stopped, the loosened part b is restored by the spring action and presses each vertical ridge 4 to the exhaust pipe 2, and the vertical ridge 4 makes the spring work. Since it is clamped by 2, the finisher can be securely attached so that it does not come off due to vibration or shock.
When the finisher is pulled, each vertical ridge 4 slides on the exhaust pipe 2 due to the bending of the free portion b, and is easily removed from the exhaust pipe 2. Also, the finisher is attached inside and not to the outside. Since it doesn't appear, the installation looks very good.

FIG. 4 shows another embodiment. In this embodiment, the holding member 3 of the exhaust pipe is formed by a thin mild steel plate.
When the finisher 1 is fitted into the exhaust pipe 2, the loose part b is plastically deformed and the vertical ridges 4 are located above the exhaust pipe because the material is poor in elasticity so that the end of the free part b can be freely moved. Since there is a tendency to separate them, the tip of the free portion b is spot-welded to the finisher 1 as shown in FIG.
This restrains the movement of the free portion to suppress plastic deformation and ensures the contact between the vertical convex strip 4 and the exhaust pipe 2. In this embodiment, since a material having excellent workability is used, it is easy to manufacture. Although the weight does not increase, the number of steps for welding the tip of the free portion increases.

C. Effect of the Invention As described above, the exhaust pipe finisher mounting means according to the present invention has the gripping member inside the finisher that allows the spring to work by the free portion, so that the spring works by simply fitting the finisher to the exhaust pipe. Therefore, it is possible to securely attach the finisher without detaching it, and moreover, the attachment and detachment of the finisher can be done easily and quickly because the free part bends and the holding member slides along the exhaust pipe.
The attached state has a characteristic that the sandwiching member does not appear to the outside, so that the appearance is good, and the finisher is well cooled by the air passing between the sandwiching members and the discoloration due to exhaust heat does not occur.
