Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a deck brush.

[0002]

2. Description of the Related Art Generally, brushes used for cleaning truck beds, ship decks, kitchens and garage floors,
A so-called "deck brush" is configured by providing a wiping body made of bristles at the tip of the handle.When using this deck brush, the portion to be washed is sprinkled with a hose or sprinkled with a bucket or the like. It gets wet, and after that, the part to be cleaned is rubbed with a deck brush for cleaning.

[0003]

In the above-mentioned general deck brush, even if the portion to be washed is sprayed with water and the portion to be washed in advance is wet, if the temperature of the portion is high, the washing water will be dried in a short time. Therefore, there is a problem that the cleaning water has to be supplied frequently, so that not only a large amount of cleaning water is wasted but also the cleaning efficiency is extremely low.

The present invention has been proposed in view of the above problems, and an object of the present invention is to provide a deck brush having an extremely high cleaning efficiency.

[0005]

In order to achieve the above object, a deck brush according to the present invention is formed in a tubular shape, and a water supply hose is connected to one end of a body portion provided with a nozzle mounting member at an intermediate portion. A hose connecting part is formed, an injection port for injecting cleaning water is formed at the other end of the body part, and a water supply passage is formed between the hose connecting part and the injection port to form a cleaning water injection nozzle, which injects water. The cleaning water jet nozzle is attached to the handle portion of the deck brush through the nozzle attachment member so that the washing water from the mouth is jetted toward the brush portion.

Further, a hose connecting portion to which a water supply hose is connected is formed at one end of a body portion having a cylindrical shape and provided with a nozzle mounting member at an intermediate portion, and a jet of washing water is injected at the other end of the body portion. A port is formed to form a water supply path between the hose connecting portion and the injection port, and a pressure reducing water discharge hole communicating with the water supply path is formed in the peripheral surface portion of the body, and the pressure reducing water discharge hole is opened. The portion is covered with an elastic member to form a washing water jet nozzle, and the washing water jet nozzle is sprayed onto the handle portion of the deck brush so that the washing water from the jet port is jetted toward the brush portion. It is also characterized in that the nozzle is mounted via a nozzle mounting member formed on the body.

Further, a hanging member is rotatably provided at an upper end portion of a handle of a deck brush having a brush at a lower end, and a water supply hose connected to a hose connecting portion is passed through the inside of the hanging member to make the handle. In some cases, the intermediate portion of the suspending member is formed in a V shape or a tapered U shape so as to prevent the water supply hose from coming off.

[0008]

In the deck brush of the present invention, when the water tap is opened after connecting the other end of the water supply hose whose one end is connected to the water tap to the hose connecting portion, the washing water supplied from the water tap is injected into the injection nozzle. Is jetted vigorously toward the brush part of the deck brush. In this state, when the worker rubs the handle of the deck brush against the desired cleaning portion, the cleaning portion is wetted by the cleaning water sprayed from the cleaning water spray nozzle and at the same time dirt is removed by the brush portion. Of.

Further, a depressurizing water discharge hole communicating with the water supply passage is formed in the peripheral surface portion of the body, and the opening portion of the depressurizing water discharge hole is covered with an elastic member to wash water supplied from a tap. When the cleaning water is higher than a predetermined water pressure, this high water pressure acts on the pressure reducing water discharge hole and resists the elastic force of the elastic member closing the pressure reducing water discharge hole. Then, the depressurizing water discharge hole is opened, and the cleaning water is discharged from the depressurizing water discharge hole, and the water pressure in the water supply passage is adjusted until the water pressure acting on the depressurizing water discharge hole and the elastic force of the elastic member are balanced (predetermined pressure). Since the water is lowered, the cleaning water sprayed from the cleaning water spray nozzle is sprayed at a substantially constant pressure even if the water pressure of the water supply source fluctuates and becomes high.

Further, a hanging member is rotatably provided at an upper end portion of a handle of a deck brush having a brush at a lower end, and a water supply hose connected to a hose connecting portion is penetrated inside the hanging member. In addition to being arranged alongside the water supply hose, the middle part of the suspension member is formed into a V shape or a tapered U shape so as to prevent the water supply hose from coming off. When it is caught or pulled, the hose portion enters the V-shape or the tapered U-shape to absorb the pulling force and prevent it from being transmitted to the hose connecting portion as the suspension member swings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a deck brush according to the present invention will be described below with reference to the drawings. FIG. 1 is an overall perspective view of a deck brush, and reference numeral 1 in the figure generally indicates the deck brush. The deck brush 1 is composed of a handle 3 having a brush 2 formed at the tip thereof, and a wash water injection nozzle 5 attached to an intermediate portion of the handle 3 via a nozzle mounting member 4.

The brush 2 is formed by implanting a synthetic resin fiber 6 which is relatively hard and rich in elasticity.

As shown in FIG. 2, the wash water injection nozzle 5 attached to the middle portion of the handle 3 is formed in a substantially cylindrical shape, and has a body portion 8 in which a water supply passage 7 is formed, and the body portion 8. Of the hose connecting portion 9 formed to project at one end, a pressure adjusting mechanism 10 formed near the other end of the body portion 8, a wash water injection port 11 and a nozzle attachment for attaching the wash water injection nozzle 5 to the handle 3. The hose connecting part 9 is composed of a member 4 and is integrally formed behind the body part 8 in the form of a short tube having a diameter substantially the same as that of the water supply hose 12 connected thereto. Three V-shaped retaining grooves 13 are formed by engraving, and a cylindrical guide cylinder 14 is formed so as to project from the end of the hose connecting portion 9.

As shown in FIGS. 2 and 3, the pressure adjusting mechanism 10 has a plate-like closing member 15 for closing the end opening of the body portion 8a formed to have a diameter larger than that of the hose connecting portion 9 to have a large diameter. Body part 8
A tube in which a circular pressure-reducing water discharge hole 16 having a diameter of about 25 mm is provided at four locations on the outer peripheral surface of a, and the opening of the pressure-reducing water discharge hole 16 is fitted to the outer periphery of the large-diameter body portion 8a The tube-shaped elastic member 17 is fixed to the large-diameter body portion 8a by a ring 18.

Reference numeral 19 in the figure denotes a protective cover formed on the outer peripheral surface of the pressure adjusting mechanism 10. In addition, the pressure adjusting mechanism 1
The diameter and number of the pressure reducing water discharge holes 16 of 0 can be set arbitrarily. Further, although the protective cover 19 and the body portion 8a are separately formed in the drawing, it goes without saying that they can be integrally formed.

As shown in FIG. 2, the wash water injection port 11 is formed by penetrating a plurality of small holes 20 communicating with the water supply passage 7 in the lower portion of the body 8a closed by the closing member 15. Has been done. Although not shown, the plurality of small holes 20 may be slits. The nozzle mounting member 4 for attaching the wash water injection nozzle 5 to the handle 3 is shown in FIGS.
As shown in FIG. 3, the front portion thereof has a substantially "gourd" shape in which a portion to be fitted to the handle 3 and a portion to be fitted to the body portion 8 of the washing water jet nozzle 5 are vertically arranged, and an intermediate constricted portion is formed. The cleaning water jet nozzle 5 is formed so as to be attached to the handle 3 by tightening the portion with a tightening tool 23 including a bolt 21 and a nut 22.

Screws 24 for positioning and preventing scratches are screwed onto the upper and lower ends of the nozzle mounting member 4 for attaching the wash water injection nozzle 5 to the handle 3, and the deck brush 1 is placed on the ground or concrete. In this case, the cleaning water jet nozzle 5 is prevented from being scratched and damaged.

Further, as shown in FIGS. 1 and 5, an annular suspension member 25 for suspending the deck brush 1 on a nail or a hook (not shown) when not in use is provided at the upper end of the handle. It is movably installed. The suspending member 25 is formed by forming a relatively thin steel wire in a semicircular shape, and fitting both ends of the suspending member 25 into a fitting hole 27 formed transparently in a lid member 26 for closing the upper end of the handle 3. It is provided so as to be rotatable about 0 ° to 90 ° with respect to the axis of
A "V" shaped protrusion 28 is formed in the center.

It should be noted that the "V" -shaped protrusion 28 formed in the central portion of the suspension member 25 can be formed in a tapered "U" shape.

The case of using the deck brush 1 formed as described above will be described below. First, the other end of the water supply hose 12, one end of which is connected to a water tap (not shown), is passed through the inside of the hanging member 5 which is approximately 90 ° with respect to the shaft center of the handle 3 to be fitted onto the guide cylinder 14. After that, the hose connecting portion 9 is fitted. Sometimes, the water supply hose 12 at the hose connecting portion 9 is fixed with a rubber band or the like.

Next, when the tap is opened, the pressure water from the tap is supplied to the water supply passage 7 through the water supply hose 12 and is jetted from the jet port 11 toward the brush 2 as shown in FIG. Therefore, the operator can hold the handle 3 and wash it while moistening a predetermined place with the water jetted from the jet port 11.

At this time, when the water pressure supplied from the tap to the water supply passage 7 is higher than a predetermined pressure, this high pressure acts on the pressure-reducing water discharge hole 16 of the pressure adjusting means 10 to reduce the pressure-reducing water discharge hole 16. Since the high-pressure water is discharged to the outside from the pressure reducing water discharge hole 16 by pushing up the elastic member 17 that closes the water supply passage 7,
Is balanced with the pressure acting on the opening area of the water discharge hole 16 for decompression and the elasticity of the elastic member 17 that closes the water discharge hole 16, that is, is maintained at a set predetermined pressure, and the water supply hose 12 is a water tap or a hose. It is prevented from coming off from the connecting portion 9.

When a worker holds the handle 3 of the deck brush 1 and a force is applied to the water supply hose 12 in the direction of pulling out the water supply hose 12 due to an intermediate portion of the water supply hose 12 being caught by another object during the cleaning operation. Along with the movement of the water supply hose 12, the water supply hose 12 at the portion penetrating the suspension member 25 at the upper end of the handle 3 bites into the “V” -shaped protrusion 28, and the suspension member 25 is shown in FIG. As shown in (3), the suspension member 25 absorbs the force in the direction in which the water supply hose 12 is tightened and the force in the direction in which the water supply hose 12 is pulled out is absorbed and prevented from being transmitted to the hose connecting portion.

In the deck brush 1 that has been cleaned, the tip of the water supply hose 12 is pulled out from the hose connecting portion 9 in a state where the hanging member 25 is set at about 90 ° with respect to the shaft core of the handle 3, and the hanging member 25 is suspended. Pull out the water supply hose 12 on the outer side of. Then, the water supply hose 12 can be easily pulled out without being hindered by the suspension member 25.

After that, the "V" -shaped protruding portion 28 of the hanging member 25 is hooked by a hanging tool such as a hook and stored.

In the above embodiment, the wash water injection port 11 is formed of a plurality of small-diameter through holes 20, but it is needless to say that it can be formed of slits. Can be omitted.

[0027]

[Effect] In the deck brush of the present invention, when the water tap is opened after connecting the other end of the water supply hose whose one end is connected to the water tap to the hose connecting portion, the cleaning water supplied from the water tap is injected into the injection nozzle. Is jetted vigorously toward the brush part of the deck brush. In this state, when the worker rubs the handle of the deck brush against the desired cleaning portion, the cleaning portion is wetted by the cleaning water sprayed from the cleaning water spray nozzle and at the same time dirt is removed by the brush portion. Of. This has the advantage that cleaning can be performed efficiently in a short time and the cleaning efficiency can be greatly improved.

Further, a pressure reducing hole communicating with the water supply passage is formed in the peripheral surface portion of the body, and the opening portion of the pressure reducing hole is covered with an elastic member so that the pressure of the washing water supplied from the tap. When the cleaning water is higher than a predetermined water pressure, this high water pressure acts on the pressure reducing hole to reduce the pressure against the elastic force of the elastic member closing the pressure reducing hole. A state in which the water pressure acting on the decompression hole and the elastic force of the elastic member are balanced (predetermined pressure) by opening the hole and discharging cleaning water from the hole
Since the water pressure in the water supply passage is lowered to 1), even if the water pressure of the water supply source fluctuates and becomes high, the wash water jetted from the wash water jet nozzle can be jetted at a substantially constant pressure. Thereby, there is an advantage that it is possible to prevent the water supply hose from being accidentally detached from the water tap or the hose connecting portion.

Furthermore, a hanging member is rotatably provided at the upper end of the handle of a deck brush having a brush at the lower end, and a water supply hose connected to the hose connecting portion is penetrated through the inside of the hanging member. In addition to arranging it along the line, the middle part of the suspension member is formed in a V shape or a tapered U shape so as to prevent the water supply hose from coming off. It is possible to prevent the hose portion from entering the V shape or the tapered U shape when it is caught or pulled and absorbs the pulling force and is not transmitted to the hose connecting portion as the suspension member swings. Of.
