Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cleaning drainage device such as a so-called court drainer used for draining ground surfaces such as tennis courts, skating rinks, and parking lots.

[Conventional technology]

The structure of a conventional cleaning drainer of this type is shown in FIGS. 8 and 9. In the conventional device, supporting arms A are provided opposite each other, a wheel C is attached to the front of each arm A via a bracket B, and a wheel C is mounted on the same axis as the wheel C and extends rearward via a swing plate R. In addition to connecting the pushed-out handle P, a flat bow-shaped traveling frame F is fixed to the rear end of the support arm A, and an elastic draining belt (sponge ) It has a structure with a WB along it (Jikko 55
-Refer to Publication No. 44601). That is, when the pushing handle P is pushed forward, the bow-shaped drain belt WB drains the ground surface while collecting water in the frame F, integrally with the traveling frame F which is pulled forward by the support arm A. I will do it.

At this time, the elastic draining belt WB provided along the back side of the traveling frame F is configured to be removably clamped by a presser plate SP attached to the back side thereof. Specifically, as shown in FIG. 9, a plurality of through holes H are bored at regular intervals at corresponding positions between the running frame F and the presser plate SP, and an elastic draining belt is sandwiched between the two. Vertical slits S are also cut at corresponding positions on the WB, and fixing devices such as bolts V and wing nuts N are passed through these and fastened. In other words, with this conventional mounting structure, if the draining belt WB wears out due to sliding, the fixing device should be loosened and the draining belt WB should be removed.
It is devised so that the necessary belt protrusion dimension α can be drawn out from the traveling frame F by lowering the belt.

[The problem that the idea aims to solve]

However, the conventional belt attachment structure described above has the following problems.

(1) When replacing the elastic drain belt or adjusting the belt protrusion dimension, a large number of bolts, wing nuts, etc. must be attached and detached one by one, which takes time and effort.

(2) The elastic drain belt needs to be set horizontally in order to prevent partial lifting from the ground surface and at the same time to prevent uneven wear, but this horizontal positioning is difficult. To solve this,
For example, it is conceivable to attach guidelines such as horizontal lines to the belt surface, but this has the disadvantage that the desired position cannot be achieved unless the long draining belt is fastened simultaneously at various points using the fixing devices, and this is not always effective. It's not a solution.

(3) Even if it is installed horizontally, since the slits are used, the vertical restraint of the elastic draining belt will not be complete, and the belt will be pulled by the frictional resistance with the ground surface, causing the belt to become localized. However, the drawback remains that it is easy to exceed the positional deviation.

The present invention was devised to solve the problems of the prior art described above, and it is possible to easily and reliably set the elastic drain belt along the running frame horizontally, and moreover, once it is set horizontally, ,
It is an object of the present invention to provide an improved cleaning draining device that does not cause positional shift during use, and has a mounting structure that allows easy attachment and detachment of an elastic draining belt and adjustment of the height, and easy maintenance. .

[Means to solve the problem]

In the present invention, the belt mounting structure of the cleaning drainer is improved as described below, in which the elastic drainer belt installed along the running frame is sandwiched between the presser plates attached to the back side of the drainer belt as described above. are doing.

That is, the running frame has horizontal protrusions protruding from it. The horizontal protrusions may be provided all around or partially around the belt running surface, and may be a single strip or multiple strips arranged vertically at appropriate intervals. On the other hand, the elastic draining belt is provided with horizontal grooves that fit into the horizontal protrusions. If there are a plurality of horizontal protrusions arranged at appropriate intervals vertically, the horizontal grooves are formed to match the intervals.

The holding plate, which clamps the elastic draining belt along the running frame, is formed of a bendable flexible band, and has a structure in which it is relatably tightened to the back surface of the elastic draining belt. That is, instead of tightening together with the draining belt using a fixture, tension is applied to the flexible band pressing plate to press and wind the back surface of the draining belt. The flexible band pressing plate that can be tightened and loosened may be a single long band-shaped plate, or may be divided into a plurality of pieces.

[Effect]

As described above, in the cleaning drainer according to the present invention, horizontal protrusions are provided on the running frame, and horizontal grooves that fit with the horizontal protrusions are provided in rows on the elastic drainer belt, so that the two can be fitted together. If they are placed along the same line, the elastic drain belt can be automatically set horizontally. Moreover, in such a fitted state, since they are engaged in the vertical direction, displacement during use is reliably prevented.
In addition, by tightening the flexible band holding plate and sandwiching the elastic draining belt, for example, one end of the holding plate can be connected to the running frame as a fixed end, and the other end can be tightened and loosened via a fastener. When coupled switchably, the elastic drain belt can be attached and detached and its position adjusted by a one-touch operation of engaging and disengaging the fastener.

〔Example〕

Embodiments of the cleaning drainer according to the present invention will be described below based on the accompanying drawings.

First, an outline of the entire apparatus according to this embodiment will be explained with reference to FIGS. 1 and 3. The device consists of a planar arcuate traveling frame 1 and a U-shaped pushing handle 4 extending diagonally rearward from the frame 1.
The running frame 1 is constructed by framing a first frame 2 which is curved into an arcuate shape by cutting out the center portion of the front side, and a U-shaped second frame 3. That is, both ends 3c, 3c of the second frame 3 are connected to the first
It is connected perpendicularly to the front end of the frame 2, and its central portion 3b extends along the front surface of the rear side of the arcuate first frame 2. In addition, Ryōryō frame 2,

The running frame 1 has an axle 5 rotatably installed in the vicinity of both ends 3c, 3c of the second frame 3, and a pair of wheels 6, 6 are attached to both ends of the axle 5, so that it can run in the front-rear direction. . Further, near the end of the second frame 3, a pair of swinging arms 7, 7 having a U-shaped cross section and having the axle 5 passed through the upper surface side thereof are provided.
is rotatably supported. Rod-shaped connecting members 8, 8 are vertically disposed at the rear end of the upper surface of each swing arm 7, and the ends of the pushing handles 4 are removably inserted into and connected to the connecting members 8, 8, respectively. I'm letting you do it.

With the above configuration, when the handle 4 is pushed, the running frame 1 moves forward using the front wheels 6, 6 as fulcrums while dragging the elastic draining belt 9 that is grounded from the rear side of the first frame 2. do.

Next, to explain in detail the belt attachment structure according to this embodiment, an elastic draining belt 9 is set on the frame 1, as shown in FIG. That is,
The first frame 2 of the running frame 1 has a pair of rail fittings 1 on both sides of the rear side, which is the belt-side surface.
0 and 10 are attached. Each rail fitting 10 has a U-shaped cross section, and is fitted from the inside of the first frame 2 so as to sandwich the first frame 2 vertically, and is placed on the back side of the first frame 2 to match its height dimension. Horizontal protrusions 10a, 10a are provided protrudingly at vertical intervals. In addition, horizontal protrusions 3a, 3a extending from the back surface of the second frame 3 located along the inner side of the first frame 2 are arranged at the center of the back surface of the first frame 2 so as to form the same trajectory as the horizontal protrusions 10a, 10a. It is installed protrudingly. Furthermore, a positioning pin 11 is provided at the center of the back surface of the first frame 2 to protrude rearward.

On the other hand, the elastic draining belt 9 extending in an arcuate manner along the back surface of the first frame 2 has the horizontal convex strip 10.
A plurality of horizontal grooves 9a, 9a are arranged in a row equally corresponding to the intervals of the grooves a, 10a, 3a, 3a. The elastic draining belt 9 is made of a suitable elastic material such as natural rubber, foam rubber, solid rubber, neoprene, etc. and has a wide width, and in an unrestrained state, it extends straight as shown in the second figure. Note that guide holes 12, 12 are arranged in a row in the center of the elastic draining belt 9, through which the positioning pins 11 are inserted.

Further, on the back side of the elastic draining belt 9, a flexible band holding plate 13 for clamping the belt 9 to the running frame 1 is attached in a circumferential manner. Flexible band holding plate 13
is formed to be slightly wider than the first frame 2, for example, as a bendable flexible band material such as a thin stainless steel plate. This flexible band pressing plate 13 is loosenably tightened from the back side of the elastic draining belt 9.
The specific mounting structure is shown in FIGS. 4 and 5. The flexible band pressing plate 13 has one end connected to the first frame 2 as a fixed end. That is, as shown in FIG. 4, one end is wound around a support shaft 14 with a bolt 15 attached, and this bolt 15 is inserted through a gate-shaped piece 16a cut and raised from a metal fitting 16 fixed to the first frame 2. , and fix it by screwing a wing nut 17 onto its insertion end. On the other hand, the tensioned end on the other end side is connected to the first frame 2 via a fastener such as a so-called snap lock. That is, as shown in FIG.
While fixing the hook 18 to the frame 2,
Rotating levers 19a and 19b provided around a support shaft are pivotally attached to the other end of the flexible band holding plate 13, and the rotating lever 19b is engaged with and disengaged from the latch 18 by turning the rotating lever 19a upside down. A fastener 19 is provided to allow the

Incidentally, in the center part 13 of the flexible band holding plate 13, there is a long hole slit 2 through which the positioning pin 11 is inserted.
0 is incised horizontally.

In the cleaning drainer configured as described above, when the elastic drainer belt 9 is attached to and detached from the traveling frame 1, the operation is performed as follows. That is, in a relaxed state of the flexible band holding plate 13 with the fastener 19 on one end side removed, the elastic draining belt 9 is interposed on the back surface of the first frame 2, and the positioning pin 11 on the frame side is inserted into the predetermined guide hole 12. and horizontal grooves 9a, 9a.
horizontal protrusions 10a, 10a, 3a on the frame side,
Insert it into 3a and install it. In this way, the horizontal setting of the elastic draining belt 9 can be easily and reliably performed. Next, from this state, slit 2
Positioning pin 11 protruding from the frame side at 0
By guiding the fastening fittings 19 to the latch fittings 18 on the frame side, the flexible band holding plate 1
3 is tensioned to evenly clamp the elastic draining belt 9 over the entire circumference of the frame (see Fig. 7). In this state, since the horizontal groove 9a and the horizontal protrusions 10a, 3a are engaged in the vertical direction, the elastic draining belt 9 will not be locally displaced at all.

Also, when adjusting the protruding dimension of the belt, by replacing the horizontal grooves 9a that fit into the horizontal protrusions 10a and 3a on the frame side using the same procedure, as shown in Fig. 7, depending on the wear of the belt, The elastic draining belt 9 can be easily fed out each time it is necessary.
In either case, the flexible band pressing plate 13 can be engaged or detached by one-touch operation of the fastener 19.

In the above embodiment, a single band was used as the flexible band pressing plate 13, but it may be divided.
FIG. 6 shows a flexible band holding plate 13A, 1 which is approximately divided into two parts.
3B is used, and while the other end (not shown) has the above-mentioned adjustable fixed end, the first frame 2 has a hook 21 on one side and a fastening metal 22 on the other side in the center of the back surface of the first frame 2 to connect both. I try to keep it tight. In this case, there are practical benefits such as being able to shorten the holding plates 13A and 13B, and the effect of exactly concealing the positioning pin 11 protruding toward the rear side is also achieved. Note that the type of fasteners and hooks does not matter.
