The hose band 10 clamps and fixes a hose (member to be fixed). Therefore, as shown in FIG. 5, the long flat plate 1 made of a metal material having holes and the like is bent to be integrated. It is configured to As shown in FIG. 1, this hose band 10 has a C-shaped circular arc portion 2 which is located at the center and is open on one side. 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 opening portions 11 with respect to the center portion, and each of the opening portions 11 is wedge-shaped so that the opening portion becomes thin as it approaches the center portion side.

At both ends of the C-shaped arc-shaped portion 2 on the opening side, square pieces 12 and 16 which are respectively bent outward are continuously provided. A rectangular piece 13 having a width narrower than that of the rectangular piece 12 is connected to one of the rectangular pieces 12, and the protruding pieces 14 are formed on both sides of the rectangular piece 13 along the connecting direction. Each of them is formed to form the first locking piece 3. On the other square piece 16, a square piece 17 is bent inwardly and continuously provided, and a fitting portion 18 into which the projections 14 and 14 are fitted is formed on the square piece 17 to form a second lock. It constitutes the piece 4.

The projecting portion 14 is a triangular wing-shaped extending piece 14 '(FIG. 5) extending from the first locking piece 3 (square piece 13).
Is formed by bending outward. Also, the first locking piece 3
The end of the (square piece 13) is bent slightly inward to form a bent portion 15, and the end of the second locking piece 4 (square piece 17) is bent slightly outward. Bending and bending part 1
9 is formed. 4A and 4B are shape explanatory views 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 protrusion 14 of the first locking piece 3 (square piece 13), as shown in FIG.
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 and 14 are formed. Also, the fitting portion 18
L3 in one direction is the length L4 of the longest part of the protrusion 14.
Formed slightly longer. With these configurations, as shown in FIG. 7, when the protrusions 14 and 14 are fitted into the fitting portion 18, the first locking piece 3 (square piece 13) and the second locking piece 4 (square piece). 17) and can be always connected in a fixed positional relationship.

Further, as shown in FIG. 8, the shape of the projection 14 is a triangular shape having a gentle oblique side on the side of the second locking piece 4 (square piece 17), and the extension line of the oblique side is approximately the first. It is formed so as to substantially follow the bent portion 15 at the end of the locking piece 3 (square piece 13). The apex angle α of the protrusion 14 is smaller than the right angle.

At the position where the rectangular pieces 12 and 16 are continuously arranged, C
A window portion 21 and a window portion 22 are formed at portions including the bent portions of the rectangular piece portions 12 and 16 with respect to the die arc portion 2. The window 22 on one side (in this example, the second locking piece 4 (square piece 16) side) has a tongue piece 23 narrower than the window 22 in the central portion on the C-shaped arc side. As shown in FIG. 2, they are arranged in series and have a shape (a bending manner) that allows a substantially circular shape to be formed along the C-shaped arc portion 2. The window 21 on the other side (first
The locking piece 3 (rectangular piece portion 12 side) is formed so as to have a larger opening area toward the center side of the C-shaped arc portion 2 than the window portion 22. This is because, as will be described later, when the hose band is in a tightened state, the C-shaped circular arc portion 2 is deformed to secure a space accommodated by the tongue piece portion 23 on the window portion 21 side.

According to the hose band 10 having the above structure, in a normal state (a state where no force is applied), as shown in FIG. 2, the first locking piece 3 (square piece 13) and the second locking piece 3 are locked. When the piece 4 (rectangular piece 17) is located away from each other and the two are brought close to each other, they tend to separate from each other due to the reaction force acting on the C-shaped arc portion 2. And, contrary to this force, the first locking piece 3
By bringing the (square piece 13) and the second locking piece 4 (square piece 17) close to each other, as shown in FIGS. 6 and 7, the protrusion 14 of the first locking piece 3 causes the second locking piece 4 to move. The fitting portion 18 can be fitted into the fitting portion 18, and the protruding portion 14 can serve 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.
Since 22 is formed, the most force acts on the center position of the C-shaped arc portion located between the openings, and the bending of this portion deforms the C-shaped arc portion 2 to deform the C-shaped arc portion in the fitted state. 2 has a substantially perfect circular shape. In addition, by making each of the openings 21 and 22 into a wedge shape in which the center side of the C-shaped circular arc portion 2 is tapered, the C-shaped circular arc portion 2 is easily deformed into a perfect circular shape when shifting to a fitting 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 end side of the spray side hose 104, and is positioned so as not to interfere with the insertion of the injection nozzle 102 (FIG. 9).
(A)). Next, the spray side hose 104 is connected to the tip of the injection nozzle 102, and the hose band 10 is connected to the hose connection portion (the portion where the injection nozzle is located under the hose) 110.
Is moved (FIG. 9B). At this time, hose band 1
Since the C-shaped circular arc portion 2 of 0 is formed larger than the diameter of the hose, the outer circumference of the spray side hose 104 can be smoothly moved.

The hose band 10 is attached to the hose connecting portion 110.
With the first locking piece 3 (square piece 13) and the second locking piece 4 (square piece 17) brought close to each other, the first locking piece 3
When the projection 14 of the second locking piece 4 is fitted into the fitting portion 18 of the second locking piece 4, the projection 14 serves as a stopper to maintain the fitted state (see FIGS. 6 and 7), so that the hose connection can be performed with one touch. The hose band 10 can be fastened (clamped) and fixed to the portion 110, and the working time can be shortened. When clamped, the tongue piece 2 formed on the window 22
3 is located in the window portion 21 on the opposite side, and the C-shaped arc portion 2 is transformed into a substantially perfect circle. And, due to the existence of the tongue piece 23,
It becomes possible to tighten the spray side hose 104 from around the
The hose can be reliably clamped from the surroundings.

The hose band 10 is clamped by
No tool is required, but even when using a tool such as pliers to reduce the force during clamping,
Unlike the conventional example, since the clamp can be performed regardless of the orientation 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 depends on the hose band 10.
Since it is determined by the circumferential length of the C-shaped arc portion 2, if the length of the C-shaped arc portion 2 is appropriately designed when 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. Occurrence can be prevented. Further, since the clamping is completed in the state where the protrusion 14 is fitted in the fitting portion 17, the degree of moderation is high and the completion of tightening can be easily determined.

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

Further, the projection 14 is formed in a triangular shape having a gentle oblique side on the side of the second locking piece, and an extension line of this oblique side is substantially along the bent portion 15 at the end of the first locking piece. Since it is formed, the oblique side of the protruding portion 14 becomes the second side when the state shifts to the fitted state due to the shape of the end portion of the second locking piece.
The protrusion 14 can be fitted into the fitting portion 18 without contacting the end of the locking piece and applying a large force.

Further, since the apex angle α of the protrusion 14 is formed to be smaller than the right angle (FIG. 8), the angle β of the bottom side of the protrusion 14 becomes 90 degrees or more, and the protrusion 14 has the angle in the fitted state. The top portion 14a is fitted so as to bite the second locking piece 4 (square piece 17) (FIG. 7), and the projection portion 14 is prevented from coming off the fitting portion 18, so that the fitting state is reliably maintained. You can

Further, when the hose band 10 is to be removed from the hose connecting portion 110 when it is necessary to replace the spray-side hose 104 due to deterioration, as shown in FIG. It is inserted between the stop piece 3 (square piece 13) and the bent portion 19, and the tip of the driver A is used as a fulcrum to move the driver A 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 fitting portion 17 of the second locking piece 4 to the projection 14 of the first locking piece 3 can be separated. The state in which the hose is sandwiched by the C-shaped arc portion 2 is released and is released, so that the detaching work can be easily performed. Further, since the bent portion 19 is formed on the second locking piece 4 (square piece 17), it is between the first locking piece 3 (square piece 13) and the second locking piece 4 (square piece 17). It makes it easy to insert the tip of the driver A into.

[0029]

According to the hose band of the present invention, the one-touch operation of fitting the protrusion of the first locking piece into the fitting portion of the second locking piece allows the hose (fixed portion) to be fixed at the C-shaped arc portion. Since the first locking piece and the second locking piece can be fixed in a state of sandwiching the member) and this state can be maintained, the fixed member can be clamped and fixed by a simple work, and the fixing work time Can be shortened. Further, the tightening force by the hose band is determined by the length of the C-shaped arc portion, so a certain tightening force can be obtained by designing to a desired length, and water leakage due to excessive tightening and poor tightening can be prevented. You can
