Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to cleaning tools for window glasses of medium-to-high-rise buildings, factories, work vehicles, ships, etc., and glass of product display cases, and particularly to window glass for medium-to-high-rise buildings. When the glass is divided into several pieces by the vertical and horizontal middle bars, various deposits (especially near the middle bars) that cannot be removed with a mop, brush, rag, etc., such as oil-containing dust, become paste-like. Next, the present invention relates to a cleaning tool for cleaning adhered substances such as dried and adhered substances and adhesive tapes, which 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 b was fitted onto the tip of the grip plate a, and was fixed with a screw c.

[Problem that the invention seeks to solve]

In conventional cleaning tools, the blade plate b is fixed to the grip plate a, in other words, the blade plate b is always exposed, so the worker's footing is particularly difficult when cleaning the windows of mid-to-high-rise buildings. tends to be unstable,
For example, he used a life rope to hold onto the window frame with one hand while leaning over half of his body while cleaning with the other hand. (It is dangerous if the blade plate b is exposed, 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. Since the item was carried in a pocket or the like, it was a dangerous item, as described above.

[Means and actions for solving problems]

The tip of the main body having a grip is configured so that the blade plate can be advanced or retracted by finger operation while gripping the grip, and the blade plate can be firmly maintained in the advanced or retracted state. When cleaning or moving, the blade plate can be inserted and removed while holding the main body with one hand.

〔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 Figure 3 is a side view (in the case where the grip is shaped like a casing, the cover plate is removed). FIG. 4 is a plan view of the bottom plate having the slit forming plate, FIG. 5 is a plan view of the blade plate, and FIG. 6 is a plan view of the operating plate.

A indicates the main body, which is roughly divided into a main body plate 1, a bottom plate 2, and a grip 3, which are integrally constructed.

A tip edge 11 having a left-right groove 11a is formed at the tip of the surface of the main body plate 1.
On the left and right sides of the front side of 1, arc-shaped guide grooves 12 are bored, each having a front locking groove 12a and a rear locking groove 12b. Reference numeral 13 indicates a contact plate fixed to the base of the surface of the main body plate 1, and reference numeral 14 indicates two leaf springs. The portion protrudes forward from the contact plate 13.

The bottom plate 2 is made of hard and highly slippery synthetic resin, and a slit forming plate 2 is formed at the base of the surface.
1 is fixed to the back surface of the main body plate 1 via the slit forming plate 21. (For example, by the screw 15 mentioned above) Also, the bottom plate 2 has an arc-shaped guide groove 22 having a front locking groove 22a and a rear locking groove 22b that match the guide groove 12 of the main body plate 1.
is worn. Note that S indicates a blade slit formed between the bottom plate 2 and the main body plate 1 by a slit forming plate 21, and 23 indicates a loose arch-shaped portion formed near the tip on the back surface of the bottom plate 2.

The grip 3 is constructed integrally with the main body plate 1, but in this embodiment, the grip 3 has a spare blade storage section 31.
is formed into a casing shape, and a cover plate 32 is fixed to this with screws 33. Note that 34 indicates a screw hole for the screw 33.

Reference numeral 4 denotes an operation plate having an operation protrusion 41 at the base of the front surface, and on the left and right sides of the back side of the operation plate, the operation plate moves within the guide grooves 12 and 22 and is fitted into the hole 51 of the blade plate 5. A pin 42 is provided protrudingly.
Note that 42a indicates a pin head.

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

Further, the front edge 43 of the operation plate 4 is fitted into the left-right groove 11a of the main body plate 1 when the blade plate is advanced.
(Note: In this state, the pin 42 is locked in the front locking grooves 12a and 22a.) When the blade retreats (when the blade 52 fits into the blade slit S)
The rear edge 44 is configured to abut against the front part of the abutting plate 13. (Note: In this state, the pin 42 is locked in the rear locking grooves 12b and 22b.) In FIGS. 2 and 3, 6 is a wooden or plastic palm fixed to the back of the grip 3. A stop plate is shown.

In the configuration described above, when the grip 3 is gripped with the thumb placed on the operation protrusion 41 of the operation plate 4 and the other four fingers placed on the back surface of the bottom plate 2, the operation plate 4 is rotated clockwise with the thumb. By rotating approximately 180 degrees to the rear locking grooves 12b and 22b.
The pin 42 that was located in the front part locking groove 12
a and 22a, and as a result of this movement, the blade plate 5 advances as shown in FIGS. 2 and 3. Also, when this advances, the front edge 43 of the operation plate 4 is aligned with the left-right groove 11 of the main body plate 1.
Fits into a. Next, move the operation panel 4 counterclockwise.
By rotating 180°, the front locking grooves 12a, 2
The pin 42, which was located at the portion 2a, moves to the rear locking grooves 12b and 22b, and this movement causes the blade portion 52 of the blade plate 5 to completely retreat into the blade slit S. Also, during this backward movement, the rear edge 44 of the operation panel 4
It comes into contact with the front part of the contact plate 13.

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

() The blade plate can be advanced or retracted while grasping a window frame or the like with one hand and gripping the handle with the other hand.

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

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