Description

Backpack power sprayer

The present invention relates to a shoulder-type power sprayer provided with a holding portion for holding a spray pipe.

A backpack type power sprayer sprays the liquid in the liquid tank through a spray pipe while an operator carries a so-called sprayer body such as a liquid tank or a power-driven pump. When the operator carries the sprayer main body without performing the spraying work, for example, the operator needs to hold the spraying pipe even when moving, which is troublesome. In order to solve such a problem, a technique for hanging a spray pipe on a sprayer body is known from Patent Document 1.

The backpack type power sprayer known from Patent Document 1 has an upward projection on the backpack frame. A spray pipe is connected to the discharge port of the pump by a hose. A holder is detachably provided on the spray pipe. By inserting the ring portion of the holder into the protrusion from above, the spray pipe can be held on the back frame.

However, there are many long hoses that are used in general carrying power sprayers. If the spray pipe is simply held on the back frame, a long hose will sway, especially during movement. As described above, when the spray pipe is not used, it is troublesome not only to block the hand, but also to move while holding the hose by hand.

The width W1 of the first pipe storage recess 43 is set to a size that allows the first spray pipe 13 to be easily inserted and removed, that is, slightly larger than the outer diameter D1 of the first spray pipe 13 (W1). > D1). Furthermore, the width W1 of the first pipe storage recess 43 is substantially the same as the width Wh of the hose storage recess 42. (W1 ≒ Wh)

The second pipe storage recess 44 is a small recess capable of storing a part of the second spray pipe 14 having a small diameter, and has a bottom surface 44b having a semicircular shape in plan view. The opening 44a of the second pipe storage recess 44 is located behind and adjacent to the bottom surface 43b of the first pipe storage recess 43 (on the front surface 11a side of the liquid tank 11 shown in FIG. 3). It penetrates through the inside 43 c of the recess 43. That is, the opening 44 a of the second pipe housing recess 44 communicates with the inside 43 c of the first pipe housing recess 43 by the communication groove 47. The communication groove 47 passes through the holding body 41 in the vertical direction. The width W2 of the second pipe storage recess 44 is set to a size that allows the second spray pipe 14 to be easily inserted and removed, that is, slightly larger than the outer diameter D2 of the second spray pipe 14 (W2). > D2). The width W3 of the communication groove 47 is set to be the same as or slightly larger than the width W2 of the second pipe housing recess 44 (W3 ≧ W2). The presence or absence of the communication groove 47 is arbitrary.

In the opening 44a of the second pipe housing recess 44 or in the vicinity thereof, left and right retaining projections 51 for retaining the second spray pipe 14 accommodated in the second pipe housing recess 44 so as to be pulled out, 51 is formed. The left and right retaining

projections

51, 51 are formed by narrowing the opening 44 a of the second pipe housing recess 44. In other words, the left and right retaining

projections

51, 51 are formed in a substantially triangular shape in plan view with the apexes facing each other. The width W4 of the opening 44a of the second pipe housing recess 44, that is, the interval W4 between the left and right retaining

projections

51, 51 is slightly smaller than the outer diameter D2 of the second spray pipe 14 (W4 <D2).

It should be noted that the left and right retaining

projections

51, 51 may have only one configuration. Even in that case, the width of the opening 44a of the second pipe housing recess 44 is W4.

In the second pipe storage recess 44, a part of the second spray pipe 14 can be stored and held by the following procedure. First, as shown in FIGS. 4 and 5, the second spraying pipe 14 removed from the first spraying pipe 13 is inserted vertically into the interior 43 c of the first pipe housing recess 43, and , And push it into the left and right retaining

projections

51, 51. As a result, a part of the resin-made holding main body 41 is elastically deformed, so that the left and right retaining

protrusions

51 and 51 are spread. The second spray pipe 14 enters the second pipe housing recess 44 while expanding the left and right retaining

projections

51, 51. 6 and 7, the second spray pipe 14 is stored and held in the second pipe storage recess 44 in a vertically oriented posture. As a result, the second spray pipe 14 can be held on the holding body 41.

Thereafter, in order to remove the second spray pipe 14 from the second pipe storage recess 44, a portion of the second spray pipe 14 exposed from the holding body 41 is directed toward the first pipe storage recess 43. Pull. As a result, a part of the resin-made holding main body 41 is elastically deformed, so that the left and right retaining

protrusions

51 and 51 are spread. The second spray pipe 14 is pulled out from the second pipe housing recess 44 while expanding the left and right retaining

projections

51, 51. Thus, the second spray pipe 14 can be removed from the second pipe housing recess 44.

Here, the force that spreads the left and right retaining

projections

51, 51 by the second spray pipe 14 can be easily put in and out of the second pipe housing recess 44, and reliably the second pipe housing recess 44. Is set to a small force that can be held in.

The belt 45 is a flexible member for opening and closing the opening 42a of the hose housing recess 42 and the opening 43a of the first pipe housing recess 43. The belt 45 closes the opening 42a of the hose housing recess 42 so that the hose 12 can be held in the hose housing recess 42, and the first pipe can hold the first spray pipe 13 in the first pipe housing recess 43. It is a member that closes the opening 43 a of the storage recess 43. Both the hose 12 and the first spray pipe 13 can be held on the holding body 41 by the single belt 45.

More specifically, one end 45 a of the belt 45 is attached to one end in the width direction of the holding body 41. The attachment position of the one end 45 a of the belt 45 with respect to the holding body 41 is preferably set near the width center of the liquid tank 11. A hooking hole 52 is formed in the other end 45 b of the belt 45. The latching hole 52 is detachably latched to the latching hook 53 formed at the other end in the width direction of the holding body 41.

The hose storage recess 42 and the first pipe storage recess 43 can store and hold each part of the hose 12 and the first spray pipe 13 by the following procedure. First, as shown in FIGS. 4 and 5, the hose 12 is vertically inserted into the hose housing recess 42 and the first spray pipe 13 is inserted vertically into the first pipe housing recess 43. . Next, the belt 45 is routed along the rear surface 41 a of the holding body 41, and the latching hole 52 is hooked on the latching hook 53. As a result, as shown in FIGS. 6 and 7, the opening 42 a of the hose housing recess 42 and the opening 43 a of the first pipe housing recess 43 are closed by the belt 45. The first spreading pipe 13 is pressed against the bottom 43 b of the first pipe housing recess 43 by the belt 45.

As shown in FIG. 5, the depth Hh from the opening 42a to the bottom surface 42b of the hose housing recess 42 is set to be larger than the outer diameter Dh of the hose 12 (Hh> Dh). For this reason, as shown in FIG. 7, when the opening 42 a of the hose housing recess 42 is closed by the belt 45, a gap is formed between the hose 12 and the belt 45. There is no fear that the hose 12 housed in the hose housing recess 42 will be crushed by the belt 45. Accordingly, the durability of the hose 12 can be sufficiently ensured. Preferably, the depth Hh is set to a distance from the opening 42a to the bottom surface 42b at the center of the width of the hose housing recess 42.

Thereafter, by removing the latching hole 52 from the latching hook 53, the hose 12 can be extracted from the hose storage recess 42, and the first spray pipe 13 can be extracted from the first pipe storage recess 43.

As shown in FIGS. 2, 8, and 9, the frame 17 for providing the liquid tank 11 has a concave receiving portion 61 opened upward. FIG. 8 shows a state in which the lower end 13 a of the first spray pipe 13 is placed on the receiving portion 61. FIG. 9 shows a state before the lower end 13 a of the first spreading pipe 13 is placed on the receiving portion 61.

More specifically, the receiving portion 61 is constituted by a recess formed in the upper surface 22 a of the horizontal plate portion 22 of the frame 17. The receiving portion 61 can receive at least the lower end 13 a of the first spreading pipe 13 held by the holding portion 40. For this reason, the 1st spreading | diffusion pipe 13 can be hold | maintained more stably by two places, the holding | maintenance part 40 and the flame | frame 17. FIG. Moreover, the liquid dripping from the lower end 13 a of the first spray pipe 13 that has been used can be received by the receiving portion 61. There is no worry of soiling the surroundings with the dripping liquid.

In other words, the receiving part 61 can receive at least the lower end 13a of the spray pipe 19 (particularly the first spray pipe 13) held by the holding part 40. For this reason, the spreading pipe 19 can be held more stably by the two portions of the holding portion 40 and the receiving portion 61. Moreover, the liquid dripping from the lower end 13 a of the spray pipe 19 that has been used can be received by the receiving portion 61. There is no worry of soiling the surroundings with the dripping liquid.

The above explanation is summarized as follows. As shown in FIGS. 2, 5, and 7, the holding unit 40 is connected to the hose storage recess 42 for storing a part of the hose 12 connected to the discharge port 15 a of the pump 15 and the hose 12.

For this reason, the hose storage recess 42 and the pipe storage recess 48 (particularly the first pipe storage recess 43) can be opened and closed easily and quickly by the single belt 45. Therefore, the hose 12 and the spray pipe 19 connected to the hose 12 can be easily and quickly held and taken out from the holding portion 40. In addition, when the spray pipe 19 is not used, it is not necessary to move the hose 12 while holding the hose 12 on the hose holding portion 40 while holding the hose 12 by hand.

Furthermore, the hose 12 and the spray pipe 19 can be stored in the holding portion 40 in a space efficient manner. Therefore, the holding structure for holding the hose 12 and the spray pipe 19 connected to the hose 12 by the holding unit 40 can be made small and easy to use.

Furthermore, as shown in FIGS. 5 and 7, the opening 43 a of the first pipe storage recess 43 is adjacent to the opening 42 a of the hose storage recess 42. For this reason, the opening 42a of the hose storage recess 42 and the opening 43a of the first pipe storage recess 43 can be easily and quickly opened and closed by the single belt 45. Therefore, the hose 12 and the first spray pipe 13 connected to the hose 12 can be easily and quickly held and taken out from the holding portion 40. Moreover, when the first spray pipe 13 is not used, it is not necessary to move the hose 12 while holding the hose 12 by the holding portion 40 while holding the hose 12 by hand.

Further, the opening 44 a of the second pipe storage recess 44 is located behind the bottom surface 43 b of the first pipe storage recess 43 and penetrates the inside 43 c of the first pipe storage recess 43. The second spreading pipe 14 is held by left and right retaining

projections

51, 51 on the back side of the first pipe housing recess 43. Therefore, the second spray pipe 14 removed from the first spray pipe 13 can be easily held in the second pipe housing recess 44. The worker Mn does not need to carry the second spray pipe 14 by hand. Further, when storing the power sprayer 10, the second spray pipe 14 may not be separately provided. For this reason, there is no worry of losing the second spray pipe 14.

Furthermore, since the hose storage recess 42, the first pipe storage recess 43, and the second pipe storage recess 44 are rationally arranged in one place, the holding unit 40 can be reduced in size. In addition, the hose 12, the first spray pipe 13, and the second spray pipe 14, that is, all of the so-called three

spray pipes

12, 13, and 14 can be stored in the holding unit 40 in a space efficient manner.

In the present invention, the spray pipe 19 is not limited to the combined structure of the first spray pipe 13 and the second spray pipe 14, and for example, only one of the first spray pipe 13 and the second spray pipe 14 is used. Includes configuration.
