JPH069B2 - Structure of the grass container attachment part in the lawn mower - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention provides a machine body with a retainer for detachably supporting a grass container, and opens and closes a lid for a grass outlet of the machine body. TECHNICAL FIELD The present invention relates to a structure of a grass container attachment portion in a freely attached lawnmower.

[Conventional technology]

As the lawn mower, a conventional lawn mower such as, for example, SAIKAI Sho 59-62
There is one disclosed in Japanese Patent No. 726. In this case, the locking tool is fixed to the machine body, and there are the following inconveniences.

[Problems to be solved by the invention]

That is, when removing the grass container, it is necessary to move the grass container and remove it from the locking tool, which is a troublesome unlocking operation. In particular, when the grass collection container is full of collected turf, the operating force required to move the grass collection container becomes large due to the weight of the collected grass, making removal of the container difficult.

An object of the present invention is to enable the locking of the grass container to be easily operated and to provide a structure therefor with a simple structure.

[Means for solving problems]

A feature of the present invention is that in the above-mentioned lawnmower, when the lid is in the first open position, it is in the engaging position,
In addition, the lid and the lid are integrally swingably mounted in a disengaged position when the lid is swung to the second open position. The action and effect thereof Is as follows:

[Action]

When the lid is operated to the second open position, the locking tool is set to the disengagement position, and the grass collection container can be unlocked without moving the grass container so as to disengage from the locking tool.

〔The invention's effect〕

The lid is lighter and smaller than the grass collection container and can be operated much easier than moving it, and the grass collection container does not have to be moved, so that the locking of the grass collection container can be easily released. , It is now possible to easily remove the grass container even if the collected grass is full.

Moreover, a simple modification is required only by changing the attachment part of the locking device from the conventional machine body to the lid body, and since the lid body can be effectively used as the operating tool of the locking mechanism, the structure can be simplified and the economical aspect is improved. I was able to take advantage.

〔Example〕

As shown in FIG. 5, it has a pair of left and right front wheels (1), (1) and rear wheels (2), (2), and a cutting blade (3) around the vertical axis (P). An engine (5) for driving the cutting blade (3) is attached to the upper part of the cutting blade housing (4) which is rotatably installed and also serves as a fuselage, and a steering handle ( 6)
Also, a walk-behind lawnmower is constructed by additionally attaching a grass collection container (7) for collecting grass.

To install the grass container (7), a bracket (8) is attached to the upper part of the cutting blade housing (4) as shown in FIGS. 1 to 4.
And the swing shaft up and down via the connecting shaft (9) to close the grass outlet (10) of the blade housing (4) for safety etc. when the grass bag (7) is removed. In order to receive and support the lid body (11) configured to be kept in the first rising open position (0 ₁ ) against the downward closing biasing spring (12),
Also, the front end side is the lid so that the grass from the grass outlet (10) does not leak out from between the rear wall (4a) of the cutting blade housing (4).
It is arranged so as to enter the lower side of (11) and contact the rear wall (4a), and the first mounting portion (7a) is locked in the recess (13) of the rear wall (4a). The rod second mounting portion (7b), which also serves as a lowering hand, is
A pair of left and right locking members (14) attached to the lid (11) are releasably engaged. In other words, it is not supported freely removable by the lid (11) a first raised open position (0 ₁₎ the cutting blade housing (4) in a state that serves to support to Sutotsupa the holdback (14).

As shown in FIG. 1, the lid body (11) has the first rising open position (0 ₁ )
Is in the position (A) where it engages with the second mounting portion (7b), and as shown in FIG. 2, the lid body (11) is in the first rising open position.
When further raised above (0 ₁ ) and swung to the second open position (0 ₂ ), the swing movement is integrally performed to the disengagement position (B) which is disengaged from the second mounting portion (7b). A pair of the locks (14), (14) are arranged in relation to the pivot pin (9). That is, the grass container (7) can be brought into the disengaged state with respect to the locking tool (14) so that the grass container (7) can be moved without removing it from the locking tool (14). , The lid (11) is pivoted to the second open position (0 ₂ ) so that the locking tool (14) is moved to the second position.
It can be removed from the mounting part (7b).

Figs. 1 and 2 are sectional views of the grass container attachment portion, and Fig. 3 shows the grass container attachment portion. FIG. 4 is a partially cutaway plan view, FIG. 4 is a cross-sectional view of a locking tool disposition portion, and FIG. 5 is a side view of the entire walking lawn mower.

Claims (1)

[Claims] 1. A machine body (4) is provided with a locking tool (14) for detachably supporting a grass container (7), and a lid body (11) for the grass outlet (10) of the machine body (4). ) Is attached to the lawn mower in such a manner that it can be freely opened and closed. When the lid body (11) is in the first open position (0 ₁ ), it is in the engagement position (A). When the lid (11) is swung to the second opening position (0 ₂ ) and is in the disengagement position (B), the locking tool (14) is present.
