Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a self-propelled sweeper that cleans floors, roads, etc. with a rotary brush provided at the bottom while moving.

[Conventional technology]

There are two types of self-propelled sweepers: self-propelled walk-behind type, in which the driver operates the sweeper using a control handle installed at the rear of the sweeper while the driver is moving, and self-propelled type, in which the driver operates the sweeper from a seat provided in the sweeper. There are two types of ride-on sweepers: self-propelled walk-on sweepers are used when cleaning small areas or for low cost, and conversely, when you want to clean large areas efficiently. Although they were more expensive than walk-behind sweepers, self-propelled ride-on sweepers were in demand, and each was used depending on its purpose.

[Problem that the invention attempts to solve]

However, since the areas to be cleaned are not limited to large or narrow areas, there are cases where it is not possible to deal with the situation sufficiently with either the walking or boarding type sweeper. The most ideal method would be to purchase two sweepers and use them depending on the location to be cleaned, but this poses the problem of increasing economic burden.

Therefore, it was considered that one self-propelled sweeper could be used in both a self-propelled walking type, in which the driver runs while driving, and a self-propelled boarding type, in which the driver rides and operates the sweeper. However, as can be seen in Figure 1 of Utility Application No. 126459/1983 (filed on August 19, 1988), conventional self-propelled boarding type sweepers all have a driver's seat and a driver's device attached to the vehicle body. Since it is installed on the top surface of the vehicle, in the case of a self-propelled walking type vehicle that operates while walking behind the vehicle body, these driver seats and driving devices become an obstruction and are not comfortable for driving. Since a separate driving device (handle, etc.) for walking only had to be installed at the rear of the vehicle body, the structure became extremely complicated and the switching operation between walking and boarding became troublesome.

Therefore, the technical problem of the present invention is to make it extremely easy to switch between the self-propelled walking type and the self-propelled riding type, and also to be able to use the driving device including the operating handle as a companion for both walking and riding. The object of the present invention is to provide a self-propelled sweeper that has a simple structure and can be manufactured at low cost.

[Means for solving problems]

The measures taken in the present invention to solve the above technical problems are as follows.

(1) A sweeper that cleans by rotating a rotary brush provided at the bottom while moving is provided with a driving device including an operating handle at the rear of the sweeper, so that the sweeper can be operated while walking.

(2) A driver's seat consisting of a support pipe bent into an approximately L-shape and a seat body attached to the tip of the support pipe is attached to the rear of the sweeper, and the sweeper is mounted on the seat body of the driver's seat. be configured so that it can be operated.

(3) The root end of the support pipe is rotatably attached to the rear of the sweeper so that the entire driver's seat can be folded forward toward the top of the sweeper.

[Effect]

The above means works as follows.

The above element (1) controls the operation of the sweeper,
The sweeper can be operated while walking using a driving device such as an operating handle provided at the rear of the sweeper.

The element (2) above controls the operation of the sweeper.
It is also possible to sit on the driver's seat provided at the rear of the sweeper and operate the driving device while riding the sweeper.

Element (3) above allows one sweeper to be easily switched between a walking type and a boarding type by simply folding the driver's seat forward to the top of the sweeper or pulling it out to the rear of the sweeper. In addition, in the case of a walk-behind version, the driver's seat is folded forward toward the top of the sweeper, allowing the driver to safely walk and drive the sweeper without being obstructed by the driver's seat.
In both cases of walking type and riding type, the sweeper can be operated using the operating handle etc. provided at the rear of the sweeper, so the operating device including the operating handle is one
To provide a sweeper for both walking and boarding at a price not much different from conventional self-propelled walking sweepers, since it is sufficient to provide a stand. As described above, the technical problem can be solved by the above-mentioned means, and the problems of the above-mentioned conventional techniques can be solved.

〔Example〕

Hereinafter, preferred embodiments of the above-mentioned self-propelled sweeper according to the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a side view of the self-propelled sweeper according to the present invention when it is made into a riding type, and Fig. 2 is a side view when it is made into a walking type. In the body of a self-propelled sweeper, 2 is a front wheel, 3 is a rear wheel serving as a driving wheel, 4 is a rotary brush that rotates in a clockwise direction in the drawing, and sweeps dirt on the floor or road surface into a dust bucket 5; is a side brush that sweeps away dirt from corners and crevices.
Reference numeral 7 denotes a lift arm for lifting and inverting the dust bucket 5 when disposing of the garbage accumulated in the dust bucket 5.

Next, what is generally indicated by the reference numeral 8 in the figure is approximately L.
A driving seat constructed of a support pipe 9 bent into a letter shape and a seat body 11 which is foldably attached to a shaft bearing part 9a provided at the tip (upper end) of the support pipe 9 using a mounting shaft 10. Although the seat body 11 is maintained in the operating condition shown in FIG. 1 by the sweeper 11a, it is structured so that it can freely rotate (fold down) in the counterclockwise direction in the drawing using the mounting shaft 10 as a fulcrum. It's on. Reference numeral 12 denotes a mounting part in which the root end of the support pipe 9 is pivotally connected to the rear lower part of the vehicle body 1, and this mounting part 12 horizontally supports the support pipe 9 and supports the entire driver's seat 8. The driver's seat 8 is configured so that it can be kept in the operating state shown in FIG. 1 while being folded and rotated so that the entire driver's seat 8 is folded forward toward the upper surface of the vehicle body 1 as shown in FIG. 2.

Furthermore, in the figure, reference numeral 13 denotes a driving device including an operating handle 14. This driving device 13 is attached to the rear of the vehicle body 1 so that its angle can be adjusted freely.
It can be fixed at any angle by tightening.

Since the self-propelled sweeper according to the present invention has the above-described configuration, when using this sweeper as a ride-on type, the operator seat 8 must be rotated rearward to set it as shown in Fig. Device 13
By adjusting the angle slightly higher, the driver can now sit on the driver's seat 8 and drive.
You can efficiently clean large areas such as warehouses and parking lots while riding the sweeper.

On the other hand, when switching the above-mentioned sweeper to a walk-behind type, the driver's seat 8 is rotated forward and folded toward the upper surface of the vehicle body 1 as shown in FIG.
By adjusting the angle of the sweeper to suit the driver, it becomes possible to drive the sweeper while walking and effectively clean various narrow spaces such as inside factories and stores.

〔effect〕

The self-propelled sweeper according to the present invention is as described above, and one sweeper can be used by switching between a walking type and a boarding type. This can be accomplished by simply folding and rotating the switch forward relative to the vehicle body side, or conversely, by simply rotating it to move it, making the changeover work extremely easy and has the advantage that anyone can do it in a short amount of time. When driving, the driver's seat is folded forward to the top of the sweeper, so you can safely walk and drive while checking what's ahead without being obstructed by the folded driver's seat. As for the driving device, it is sufficient to install one device for both walking and riding at the rear of the vehicle, and furthermore,
The operator's seat can also be easily manufactured using pipes, etc., so even though it can be used as a companion to both walking and boarding type sweepers, it can be manufactured at a low price that is not much different from that of conventional walking type sweepers. It can also exhibit economic advantages, and its practical value is extremely high.
