Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a starting device for an outboard motor, particularly a recoil starter for starting an engine. The present invention relates to a starting device for an outboard motor.

0002

[Conventional technology]

An outboard motor is a type of motor that is mounted on the rear of the hull of a small vessel (boat, etc.) and operated directly by the operator. It is widely used as a source of progress. For this reason, outboard motors are mechanically It has been simplified to make it smaller and lighter. Therefore, for engine starting The vessel is not equipped with an electric starter, etc., and the operator must directly turn the recoil starter. The outboard motor is started by turning the engine.

0003 A series of these operations will be explained based on FIGS. 3 to 5. In Figure 5, A conventional outboard motor 20 is shown. This outboard motor 20 has a rope ( (not shown), forcefully pull out the grip 10 connected to the boat operator side F, The engine 15 is started by rotating the recoil starter 16. and, By releasing the grip 10 after starting the engine, the grip 10 can be attached to a rope (not shown). ) is stored in the rope guide 14, and the grip 10 returns to the specified position. Ru.

0004 In FIG. 3, the grip 10 is shown in a stored state. Also, in Figure 4, the group The fitted state of the lip 10 is shown. The engine cover 13 on the operator side shown in FIG. A grip guide 11 having a grip fitting opening 11a in a truncated conical taper hole seals. It is attached via a material 12. Grip insertion opening 11 of this grip guide 11 In a, the other end of the grip 10 has a grip insertion portion 1 having a conical tapered shape. 0a is provided, which fits into the grip fitting opening 11a described above when storing the grip. This prevents moisture such as seawater from entering the inside of the engine cover 13. It has a structure that is also waterproof.

[0005] In the fitting part configured in this way, the shape of the fitting part is a conical three-dimensional shape. Since the grip 10 has a circular cross-sectional shape, the grip 10 is The pool 10 can be freely rotated and stored. Therefore, the single-character grip 10 is constantly The vehicle will be held in a different position.

[0006] For this reason, each time you start the engine, turn the grip 10 into a position that is easy to grip. This causes the lip 10 to be pulled, making it difficult to start the engine quickly. these As one of the means to solve this problem, a starting system for outboard motors was developed in Tokusho 58-164496. location is suggested. The starting device for this outboard motor consists of a grip 30 as shown in FIG. The grip insertion part 30a provided in the rope guide 31 and the fitting part 31 provided in the rope guide 31 a and each have a protrusion, and each has a recess for accommodating the other protrusion. Because of this structure, the grips 30 in the shape of a single letter are made by fitting these parts alternately. It is constantly held in a predetermined position.

[0007]

[Problem that the idea aims to solve]

However, in the conventional outboard motor starter mentioned above, the fitting part has an uneven shape. Due to the complexity, it is not possible to achieve tight contact around the entire circumference of the mating part when mating them together. It is difficult to maintain airtightness, and there are disadvantages such as poor waterproofness at the grip fitting part. there were.

[0008]

[Purpose of invention]

The purpose of the present invention is to improve the inconveniences of the conventional example, and to provide particularly stable waterproof performance. The purpose of the invention is to provide a starting device for an outboard motor that can maintain the following conditions.

[0009]

[Means to solve the problem]

In this invention, the recoil starter for engine starting and this recoil starter are integrated. The other end of the rope is inserted through the opening of the rope guide. In an outboard motor starting device which is secured to a grip, the cross-sectional shape of the opening is has an elliptical shape, and this cross-sectional shape has a certain proportion to the recoil star. The rope locking part of the grip is connected to the opening. The structure has been adopted such that it is formed in accordance with the above. Through these, we achieved the above objectives. It is intended to be used.

0010

[Effect]

The cross section of the rope guide is shaped like an elliptical truncated cone, and the shape is convergent toward the inside. It is formed so that it can fit into the grip fitting hole formed in the bundle. The grip insertion portion contacts and is guided along the shape of the fitting portion while sliding. others Therefore, the long and short axes of the mutual cross-sectional shapes are placed in a predetermined position. They fit together in the same position.

[0011]

[First example] Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1 and 2. Figure 1 Smell Reference numeral 2 indicates a rope guide made of an elastic member, reference numeral 5 indicates a rope, and reference numeral 4 indicates an elastic member. Each grip comprising a sex member is shown. The rope guide 2 has an oval cross-sectional shape. The cross-sectional shape is converged at a constant rate from the outer surface 2a to the inner surface 2b. A grip fitting opening 1 is provided. Then, insert this grip fitting opening 1. One end of the rope 5 is latched to a recoil starter (not shown) via the recoil starter. one On the other hand, a grip insertion part 3 provided on the grip 4 is locked to the other end of the rope 5. The grip insertion portion 3 has a shape similar to the grip insertion opening 1 described above. This is the configuration that was adopted.

0012 Next, the operation of this embodiment will be explained. In Figure 1, the outboard motor engine (Fig. (not shown) At the time of starting, the recoil starter (not shown) is connected via rope 5. Pull out the tied grip 4 forcefully toward the operator's side M, and remove the recoil starter (not shown). (not shown) to start the engine (not shown). And en By releasing the grip 4 after starting the engine, it is stored in the rope guide 2 together with the rope 5. Then, the grip 4 returns to the predetermined position.

[0013] At this time, the grip insertion part 3, which is a convex part shaped like a truncated elliptical cone, is not pulled by the rope 5. Grip fitting opening 1 has an elliptical cross section and converges at a predetermined rate toward the inside. They come into contact and are guided along the shape while sliding. And these mating parts are mutually Since the shapes are similar, the long and short axes of the mutual cross-sectional shapes can be placed in the same position. It will be something that fits in the space. Therefore, the monogram-shaped grip is constantly stopped in a predetermined position. He will be retained.

[0014] In addition, the fitting portion between the grip fitting opening 1 and the grip insertion portion 3 is arranged in the fitting direction. Since it has a taper that converges with a predetermined convergence rate according to each, , the grip insertion part 3 is pulled into the grip insertion opening 1 by the rope 5. By doing so, they alternately enter into contact with each other. Furthermore, these cross-sectional shapes Since the shape is elliptical, the abutment part is at least in one part, and the entire cross-sectional shape is Since there is a line contact around the circumference, airtightness is created.

[0015]

[Effect of the idea]

As described above, according to the present invention, the grip fitting hole provided in the rope guide has an elliptical cross-sectional shape and is formed by converging at a constant rate toward the mating direction. Both have a structure in which one end of the grip to be inserted is formed in accordance with the grip fitting hole. Since the grip is held in a fixed position, the grip is constantly held in a predetermined position. This has the effect of creating airtightness at the mating part, thus maintaining waterproofness. . This not only helps maintain the startability of the outboard motor, but also prevents moisture such as seawater from penetrating inside the outboard motor. This is an unprecedented advantage in that it can extend the lifespan of outboard motors by preventing water damage. It is possible to provide a starting device for an outboard motor.
