JPH068B2 - 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]

The present invention is characterized in that, in the lawnmower described above, the locking member is movably attached to an engagement position and an engagement release position, and the lid body is in the first open position. When the locking tool is in the locking position and the lid is swung to the second opening position, the locking tool is in the disengagement position and the lid and the locking tool are interlocked. The mechanism and the effect thereof are as follows.

[Action]

When the lid is operated to the second open position, the locking member is set to the disengaged position because of the interlocking mechanism, and the grass container can be unlocked without moving the grass container so as to disengage from the locking device.

〔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.

Since the lid can be effectively used as an operating tool for switching the locking tool to the disengagement position, the locking tool operating tool can be simplified in structure and economically advantageous.

〔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 bag (7) for collecting grass.

To attach the grass collection bag (7), as shown in FIGS. 1 to 4, a bracket is provided on the upper part of the cutting blade housing (4).
(8) and the connecting shaft (9) so that it can be swung up and down to open and close, and when the grass bag (7) is removed, the grass outlet (10) of the blade housing (4) can be used for safety, etc. The lid (11) configured to be closed for lowering the closing spring (12)
So that the lawn from the lawn discharge port (10) can be received and supported at the first rising open position (0 ₁ ) against the cutting blade housing (4).
The rear end (4a) and the rear end (4a), so that the front end side enters the lower side of the lid (11) and contacts the rear wall (4a), and the shape retention frame ( The bottom that forms the grass transfer path (15) of the cutting blade housing (4) with the first fixture (14) connected to the cutting blade housing (4) inserted into the cutting blade housing (4) from the grass discharge port (10). A second mounting tool (17) made of a rod which is placed and locked on the wall member (16) and which is also connected to the shape retention frame (13) and also serves as a lowering hand,
A pair of left and right locking tools (18), (18) attached to the upper part of the cutting blade housing (4) are releasably engaged. In other words, it is not supported freely removably by a cover body (11) a first raised open position (0 ₁₎ the bottom wall member in a state that serves as a stopper for supporting (16) locking tool (18).

An engaging position (A) in which the front end side of the action portion (18a) projects outside the cutting blade housing (4) from each of the pair of locking members (18) and (18).
And the action part (18a) swings up and down to the disengagement position (B) retracted to the turf transfer path (15) and can be restored to the engagement position (A) by the elastic restoring force. It is made of a leaf spring as described above, and an interlocking pin (20) attached to the bracket (8) via a boss (19) so as to be vertically slidable is interlocked with the lid body (11). The locking tool (18) is the second one so that the weed bag (7) can be brought into a disengaged state with respect to the locking tool (18) without the lifting operation of the weed bag (7). It is constructed so that it can be detached from the fitting (17) and can be detached by swinging the lid (11).

That is, as shown in FIG. 1, when the lid body (11) is in the first raised open position (0 ₁ ), the lid body (11) moves the interlocking pin (20).
And the locking member (18) is in the engagement position (A) due to the habit, and as shown in FIG. 2, the lid body (11) is moved to the first rising and opening position. When the swing operation is performed from (0 ₁ ) to the second open position (0 ₂ ) further raised, the interlocking pin (20) is pushed down by the lid (11) and the locking tool (18) is engaged. It is pushed down to the release position (B).

When the grass bag (7) is attached to the cutting blade housing (4), the second attachment tool (17) disengages the locking tool (18) from the disengagement position (B).
Each of the pair of forming tools (18) and (18) is provided with an inclined portion (18a) that abuts so as to push it down to the second attaching tool so that the weeding bag (7) can be attached. It is configured to be engaged with the pair of locking tools (18), (18) only by pushing the (17) into the space between the cutting blade housing (4) and the bracket (8).

[Another embodiment]

A link mechanism or the like may be adopted instead of the interlocking pin (20), and these are collectively referred to as the interlocking mechanism (20).

The grass collection bag (7) can be changed to a basket or the like, and these are collectively referred to as a grass collection container (7).
