DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a hose band according to the present invention will be described with reference to the drawings.
1 is a perspective view of the hose band, FIG. 2 is a front view of the hose band, and FIGS. 3 (a), 3 (b) and 3 (c) are left side view, right side view and bottom view of the hose band, respectively. FIG.

The hose band 10 is formed by bending an elongated flat plate 1 made of a metal material having holes and the like as shown in FIG. 5 in order to clamp and fix a hose (member to be fixed). It is structured. As shown in FIG. 1, the hose band 10 has a C-shaped arc portion 2 located at the center thereof and having one side opened. The C-shaped arc portion 2 is formed by bending the central portion of the flat plate 1 into an arc shape. The C-shaped arc portion 2 is provided with a pair of openings 11 with respect to the center portion, and each of the openings 11 has a wedge shape that is closer to the center portion side and thus has a narrower opening portion.

At both ends on the opening side of the C-shaped arc-shaped portion 2, square pieces 12 and 16 which are bent outward are respectively provided in series. A rectangular piece 13 having a width smaller than that of the rectangular piece 12 is continuously provided on one of the rectangular pieces 12 by being bent inward. Protrusions 14 are provided on both sides along the direction in which the rectangular pieces 13 are provided. Each of them is formed to form the first locking piece 3. The other rectangular piece 16 is provided with a rectangular piece 17 which is bent inward and is connected to the other rectangular piece 16. A fitting portion 18 is formed on the rectangular piece 17 so that the projections 14, 14 are fitted thereto. A piece 4 is constituted.

The protrusion 14 is a triangular wing-shaped extension piece 14 ′ (FIG. 5) extending from the first locking piece 3 (square piece 13).
Is bent outward. Also, the first locking piece 3
The end of the (square piece 13) is slightly bent inward to form a bent portion 15, and the end of the second locking piece 4 (square piece 17) is slightly bent outward. Bend part 1
9 are formed. FIGS. 4A and 4B are explanatory diagrams of the shape when the rectangular pieces 13 and 17 are viewed from the direction of the arrow in FIG.

The fitting portion 18 is formed at a position facing the projection 14 of the first locking piece 3 (square piece 13).
As shown in (a) and (b), the width L1 of the fitting portion 18 is configured to be slightly wider than the width L2 of the rectangular piece 13 on which the protrusions 14 are formed. Also, the fitting portion 18
Is the length L4 of the longest part of the projection 14
It is formed slightly longer. With these configurations, as shown in FIG. 7, when the projections 14, 14 are fitted to the fitting portions 18, the first locking pieces 3 (square pieces 13) and the second locking pieces 4 (square pieces) 17) can always be connected in a fixed positional relationship.

As shown in FIG. 8, the projection 14 has a triangular shape having a gentle hypotenuse on the side of the second locking piece 4 (square piece 17), and the extension of the hypotenuse is substantially the first. The locking piece 3 (square piece 13) is formed so as to substantially extend along the bent portion 15 at the end thereof. The apex angle α of the projection 14 is smaller than a right angle.

Each of the square pieces 12 and 16 has a C
A window 21 and a window 22 are formed in portions including the portions where the rectangular pieces 12 and 16 are bent with respect to the mold arc 2. On one side of the window 22 (in this example, on the side of the second locking piece 4 (square piece 16)), a tongue piece 23 narrower than the window 22 is provided at the center of the C-shaped arc. As shown in FIG. 2, the shape is such that a substantially circular shape can be formed along the C-shaped arc portion 2 (how to bend). Window 21 on the other side (first
The locking piece 3 (square piece 12 side) is formed to have a larger opening area on the center side of the C-shaped arc 2 than the window 22. This is because a space for accommodating the tongue piece 23 is secured on the window 21 side by deformation of the C-shaped arc portion 2 when the hose band is in a tightened state, as described later.

According to the hose band 10 having the above structure, in a normal state (a state in which no force is applied), the first locking piece 3 (square piece 13) and the second locking piece are used as shown in FIG. When the pieces 4 (square pieces 17) are located away from each other and approach each other, they tend to move away from each other due to the reaction force acting on the C-shaped arc portion 2. Then, contrary to this force, the first locking piece 3
By bringing the (square piece 13) and the second locking piece 4 (square piece 17) closer to each other, the projection 14 of the first locking piece 3 is moved to the second locking piece 4 as shown in FIGS. And the projection 14 serves as a stopper to maintain the fitted state.

When the hose band 10 shifts from the normal state to the fitted state, the opening 21 is formed in the C-shaped arc portion 2.
22 is formed, the most force acts on the center position of the C-shaped arc portion located between the openings, and when this portion is bent, the C-shaped arc portion 2 is deformed and the C-shaped arc portion in the fitted state is formed. 2 has a substantially perfect circular shape. Further, by forming each of the openings 21 and 22 into a wedge shape in which the center side of the C-shaped arc portion 2 is tapered, the C-shaped arc portion 2 is easily deformed into a perfect circular shape when shifting to the fitted state. ing.

Next, the operation of connecting the hose band 10 having the above structure to the injection nozzle of the hose reel will be described with reference to FIG. First, the hose band 10 is inserted into the tip side of the spraying-side hose 104, and is positioned so as not to interfere with the insertion of the injection nozzle 102 (FIG. 9).
(A)). Next, the spraying side hose 104 is connected to the tip of the spray nozzle 102, and the hose band 10 is connected to the hose connection portion (the portion where the spray nozzle is located below the hose) 110.
Is moved (FIG. 9B). At this time, hose band 1
Since the C-shaped arc portion 2 of 0 is formed larger than the diameter of the hose, the outer circumference of the spraying side hose 104 can be moved smoothly.

The hose band 10 is connected to the hose connecting portion 110.
Is positioned, the first locking piece 3 (square piece 13) and the second locking piece 4 (square piece 17) are brought closer to each other to make the first locking piece 3
When the protrusion 14 is fitted to the fitting portion 18 of the second locking piece 4, the protrusion 14 functions as a stopper to maintain the fitted state (see FIGS. 6 and 7), so that the hose can be connected with one touch. The hose band 10 can be fastened (clamped) to the part 110 and the working time can be reduced. At the time of clamping, the tongue piece 2 formed in the window 22
3 is located in the window 21 on the opposite side, and the C-shaped arc portion 2 is deformed into a substantially perfect circle. And, due to the presence of the tongue piece 23,
The spraying side hose 104 can be tightened from almost the periphery,
The hose can be reliably clamped from the surroundings.

The clamps of the hose band 10 include:
Although no tools are required, even when using tools such as pliers to reduce the force required for clamping,
Unlike the conventional example, since the clamp can be performed regardless of the direction of the tool, the guide plates 101a (FIG. 11) at both ends of the cylindrical reel portion 101 do not interfere with the clamping.

The tightening force of the hose is
Therefore, if the length of the C-shaped arc portion 2 is appropriately designed at the time of designing the hose band, the tightening force at the time of clamping can be made constant, and excessive tightening and water leakage can be prevented. Generation can be prevented. In addition, since the clamping is completed in a state where the projections 14 are fitted to the fitting portions 17, it is possible to easily determine the completion of the tightening with a high sense of moderation.

The end of the first locking piece 3 (square piece 13) is bent inward to form a bent portion 15 and the end of the second locking piece 4 (square piece 17). Since the bent portion 19 is formed by bending the side outward, the first locking piece and the second locking piece do not hit each other when the first locking piece and the second locking piece are brought close to each other. Can be promptly shifted to a fitting state in which the projection 14 of the second engagement piece 4 is fitted to the fitting portion 18 of the second locking piece 4.

Further, the shape of the projection 14 is a triangular shape having a gentle hypotenuse on the side of the second engagement piece, and an extension of this hypotenuse substantially extends along the bent portion 15 at the end of the first engagement piece. Since it is formed, in combination with the shape of the end of the second locking piece, the oblique side of the projection 14 is shifted to the second position when shifting to the fitting state.
The protruding portion 14 can be fitted into the fitting portion 18 without a large force by abutting along the end of the locking piece.

Also, since the apex angle α of the projection 14 is formed at an angle smaller than the right angle (FIG. 8), the angle β of the base of the projection 14 becomes 90 degrees or more, and The top portion 14a is fitted so as to bite the second locking piece 4 (square piece 17) (FIG. 7), and the projection 14 is prevented from coming off the fitting portion 18 to maintain the fitted state reliably. Can be.

Further, when the hose band 10 is detached from the hose connection portion 110, for example, when it is necessary to replace the spraying hose 104 due to deterioration, as shown in FIG. The first locking piece 3 (square piece 13) is inserted between the stop piece 3 (square piece 13) and the bent portion 19, and the driver A is moved in the direction of the arrow in FIG. ) And the second locking piece 4 (square piece 17) can be easily separated from each other by the principle of leverage, and the projection 14 of the first locking piece 3 can be separated from the fitting portion 17 of the second locking piece 4. Is released, and the state in which the hose is sandwiched by the C-shaped arc portion 2 is released, so that the attaching and detaching operation can be easily performed. In addition, since the bent portion 19 is formed on the second locking piece 4 (square piece 17), between the first locking piece 3 (square piece 13) and the second locking piece 4 (square piece 17). The tip of the driver A is easily inserted into the driver A.

[0029]

According to the hose band of the present invention, the hose (fixed) is formed at the C-shaped arc by one-touch operation of fitting the projection of the first locking piece to the fitting portion of the second locking piece. The first locking piece and the second locking piece can be fixed and maintained in a state in which the member is sandwiched, so that the member to be fixed can be clamped and fixed by a simple operation, and the fixing work time Can be shortened. In addition, since the tightening force of the hose band is determined by the length of the C-shaped arc portion, it is possible to obtain a constant tightening force by designing the hose to a desired length, and to prevent water leakage due to over-tightening or poor tightening. Can be.
