Description

[Detailed description of the invention] [Industrial application field].

The present invention relates to a tool for cleaning window glass of medium-to-high-rise buildings, factories, working vehicles, ships, etc., and glass of product display cases, and particularly to cleaning tools for cleaning window glass of medium-to-high-rise buildings, which are divided into several pieces by vertical and horizontal middle bars. Various deposits that cannot be removed with motu, plush, rags, etc., such as oil-containing dust, become paste-like, and then dried and adhered deposits and adhesive tape. This article relates to a cleaning tool for cleaning deposits such as those that are difficult to remove without scraping with a blade plate.

[Conventional technology]

A device as shown in FIG. 1 was used to remove and clean the above-mentioned deposits. That is, the base of the blade plate was fitted onto the tip of the grip plate a, and the grip plate was fixed with screws C.

[Problem that the invention seeks to solve]

In conventional cleaning tools, the blade plate is fixed to the grip plate a, in other words, the blade plate is always exposed, so it is difficult to use the worker's footing especially when cleaning the windows of medium and high-rise buildings. He tended to be unstable, for example, using a life rope to hold onto the window frame with one hand while leaning forward and cleaning with the other hand.

(It is dangerous to expose the blade plate, so put cleaning tools in your pocket etc. when moving.) Also, when using a gondola, hold the rim with one hand while cleaning with the other hand, and when getting on and off the gondola, clean it with the other hand. Because it was carried in a pocket, etc., it was a risky item, as described above.

[Means and actions for solving the problem] A blade plate is advanced or retracted by finger operation while gripping the tip of the main body having a grip p, and the blade plate can be moved forward or backward, and the blade plate can be moved forward or backward. By being configured so that it can be firmly held, the blade plate can be moved in and out while holding the main body with one hand when cleaning or moving.

〔Example〕

Figures 2 to 6 show an embodiment of the present invention. Figure 2 is a partially cutaway plan view, Figure 3 is a side view, and (in the case where the grip portion is shaped like a casing, one plate of the grip portion is removed). case) 4th
The figure shows a plan view of the bottom plate having the slit forming plate, FIG. 5 shows a plan view of the blade plate, and No. 6 shows the operation plate.

The main body is roughly divided into a main body plate 1, a bottom plate 2, and a grip-tei, and the ribs etc. are integrally constructed.

A tip edge 11 having a left-right groove lla is formed at the tip of the surface of the main body plate 10, and a front locking groove 12a and a rear locking groove 12b are formed on the left and right sides of the front side of the tip edge 11, respectively.
A guide groove 12 having an arc shape is bored. 13
Reference numeral 14 indicates a contact plate fixed to the base of the surface of the main body plate 1, and 14 indicates two leaf springs. A portion protrudes forward beyond the contact plate 13.

The bottom plate 2 is made of hard and highly slippery synthetic resin, and a slit-forming plate 21 is fixed to the base of its surface, and is also fixed to the back surface of the main body plate 1 via the slit-forming plate 21. . Further, an arc-shaped guide groove 22 having a front locking groove 22a and a rear locking groove 22b, which match the guide groove 12 of the main body plate 1, is bored in the bottom plate 2 (for example, by the screws 15 mentioned above). Note that S is a blade plate slit formed between the bottom plate 2 and the main body plate 1 by the slit forming plate 21;
3 shows a gentle arch-shaped portion formed near the tip on the back surface of the bottom plate 2. As shown in FIG.

The grip 3 is constructed integrally with the main body plate 1, and the grip 3 in this embodiment has a replaceable blade storage portion 31 formed in the shape of a casing, to which a cover plate 32 is fixed with screws 33. Note that 34 indicates the twist and hole of the screw 33.

Reference numeral 4 indicates an operating plate having an operating protrusion 41 at the base of the front surface, and on the left and right sides of the back surface of the operating plate, there are provided operating plates that move within the guide grooves 12 and 22 and are fitted into the holes 51 of the blade plate 5. A bottle 42 is provided protrudingly.

Note that 42a indicates a bin head.

The operation plate 4 is superimposed on the main body plate 1, and the bottle 42 is
The two leaf springs 14 are inserted into the guide groove 12 of the main body plate 1, the hole 51 of the blade plate 5 slidably fitted in the blade slit S, and the guide groove 22 of the bottom plate 2. The tip is pressed against the main body plate 1.

In addition, the front edge 43 of the operation plate 4 is fitted into the left-right direction*1ta of the main body plate 1 when the blade plate is advanced (Note: In this state, the bottle 42 is inserted into the front locking grooves 12& and 22& (It is locked.) When the blade plate is retracted (the blade part 52 is a sling for the blade plate)
When inserted into S), the rear edge 44 is configured to abut against the front part of the contact plate 13. (Note: In this state, the bottle 42 is locked in the rear locking grooves 12b and 221). ) In Fig. 2.3, reference numeral 6 indicates a palm resting plate made of wood or plastic and fixed to the back of the grip 3.

In the configuration on paper, the toga finger is connected to the operation protrusion 41 of the operation plate 4.
While gripping the grip 3 with the other four fingers touching the back surface of the bottom plate 2, rotate the operating plate 4 approximately 180 degrees clockwise with your toga fingers to engage the rear locking groove 12b. The bin 42, which was located at the portion 22b, moves to the front locking grooves 122L and 221L, and this movement causes the blade plate 5 to advance as shown in FIG. 2.3. Also, when this advances, the front edge 43 of the operation plate 4 is aligned with the left-right groove 1 of the main body plate 1.
1&. Next, move the operation panel 4 counterclockwise approximately 180 degrees.
By rotating .degree., the pin 42, which was located in the front locking grooves 121L and 22L, is moved to the rear locking groove 12b.

22b, and as a result of this movement, the blade portion 52 of the blade plate 5 completely retreats into the blade plate slit S. Also, the rear edge 44 of the operation plate 4 comes into contact with the front part of the contact plate 13 when the operation plate 4 is moved backward.

According to the gist of the present invention, the following effects can be achieved.

(I) While grasping a window frame etc. with one hand, the blade plate can be advanced and retreated with the other hand gripping.

(IF) The above operations can be performed easily and quickly.

(g) Since the advanced and retracted states of the blade plate can be firmly maintained, the work can be performed with certainty, and it can be carried and stored safely.
