Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a joint for changing the angle of a bar-shaped handle of a cleaning mop, a draining tool for glass, and other tools.

BACKGROUND ART In cleaning mops, drainers for glass or floors, and other tools that have a rod-shaped handle and require a relatively large force when used, the handle is fixed to the tool. If it is appropriate to give the handle an angle, the angle is given to the handle by making the handle slope at the fixed part or by interposing a pipe bent at an appropriate angle. Therefore, it is impossible to change the angle of the handle depending on the place of use, the state of use, or the user's wishes, making it difficult to use cleaning tools and the like.

The present invention is intended to solve the above-mentioned problems, and aims to provide an arbitrary angle to a rod-shaped handle and to prevent the angle of the handle from changing unnecessarily during use.

The joint of the present invention has a pair of casings each having a concave cross section, with their recesses facing each other, and the ends of their peripheral walls joined together, and the pair of casings are provided at their center. A connecting body that is rotatably connected by a support shaft, has a connecting body that is slidable in the axial direction of the support shaft and biased toward one of the casings by a spring in the opposing recesses of a pair of casings, and is connected. Locking protrusions that engage with each other are provided on opposing surfaces of the body and the pair of casings, a moving means is provided for moving the connecting body against the force of the spring, and a connecting rod is provided on the peripheral wall of each casing. It is characterized by the fact that it is provided.

In this joint, the locking convex part of the connecting body is always engaged with the locking convex parts of both casings, so it is impossible for each casing to rotate arbitrarily, and the connecting rod provided on them The positional relationship remains unchanged. Then, the connecting body is moved by the moving means against the force of the spring, and the locking convex portion of the connecting body is engaged with the locking convex portion of the casing on the side in the direction in which the connecting body is biased by the spring. When released, each casing becomes rotatable and the positional relationship of the connecting rods can be changed.

An embodiment of the joint of the present invention will be described with reference to FIGS. 1 to 4. Reference numeral 1 denotes a casing having a concave cross section, and is composed of a cylindrical peripheral wall 2 and a top wall 3 with one end thereof closed. Reference numeral 4 denotes a casing, which is composed of a cylindrical peripheral wall 5 and a supporting wall 6 integrally provided with the peripheral wall 5 at the middle part in the longitudinal direction, and the casings 1 and 4 have their recesses facing each other. , and surrounding wall 2,
5 are connected to each other so as to be rotatable relative to each other. Reference numeral 7 denotes a support tube erected at the center of the top wall 3 inside the casing 1; 8 is a support shaft that is inserted into the support tube 7 and passes through the support wall 6; The other end has a pipe shape and is divided into a plurality of pieces in the circumferential direction, and a locking piece 10 protruding from the outside of the tip is locked to the support wall 6, and the supporting shaft is At 8, the casings 1 and 4 are rotatably connected to each other. A locking protrusion 11 is provided on the inner surface of the peripheral wall 2 of the casing 1 in the longitudinal direction, and a locking protrusion 12 is provided on the inner surface of the peripheral wall 5 of the casing 4 in the longitudinal direction.

Reference numeral 13 denotes a ring-shaped connecting body inserted into the opposing recesses of the casings 1 and 4, which is shorter than the length of the peripheral wall 2, is slidable in the axial direction of the support shaft 8, and has an outer peripheral surface. The locking convex portion 11,
12, and is biased toward the casing 4 by a spring 15.

Reference numeral 16 denotes a push button attached to the casing 4, and a pressure rod 17 protruding from the inner and outer periphery of the push button is passed through the support wall 6 to push the connecting body 13 against the force of the spring 15. ing. The pressurizing rod 17 is configured such that a projecting piece 18 provided on the side surface of its tip is engaged with a stepped portion provided on the peripheral wall 5 so that the pressurizing rod 17 is not separated from the casing 4 unnecessarily. 19 is a connecting pipe protruding from the outer surface of the peripheral wall of the casing 1;
is a connecting pipe protruding from the outer surface of the peripheral wall of the casing 4.

In this example, the support shaft 8 is formed separately from the casing 1, but the support tube 7 formed integrally with the top wall 3 may be made longer to serve as the support shaft.

This joint is used by inserting the connecting pipe 19 into a pipe serving as a handle 21 and inserting the connecting pipe 20 into a mounting pipe 23 attached to a drainer 22, as illustrated in FIG. Normally, as shown in FIG. 1, the connecting body 13 biased by the spring 15
5, and its locking protrusion 1
4 is locked to both the locking convex portion 11 of the casing 1 and the locking convex portion 12 of the casing 4. That is, since the connecting body 13 unrotatably connects both the casings 1 and 4, the connecting pipes 19 and 20
remains constant.

To change the positional relationship between the connecting pipes 19 and 20, press the push button 16. Then, pressure rod 1
7 to move the connecting body 13 toward the casing 1 against the force of the spring 15 and separate the connecting body 13 from the peripheral wall 5 of the casing 4, so that the casings 1 and 4 can be freely rotated. . Therefore, in this state, the positional relationship between the connecting pipes 19 and 20 is set to the required state, the push button 16 is released, and the connecting body 1
3 toward the casing 4 by the force of the spring 15, making the casings 1 and 4 unrotatable. If only the push button 16 is released, the connecting pipes 19, 2
0 is not fixed, by slightly changing their angle, the locking protrusion 14 will engage with the locking protrusion 12, the connecting pipes 19 and 20 will become immovable, and their positional relationship will not change unnecessarily. .

FIG. 6 shows a second embodiment, in which the center portion of the connecting body 13 on the casing 4 side projects into the casing 4. A cam lever 24 for pressurizing or releasing the connecting body 13 is pivotally attached to the end of the support shaft 8. The protruding portion of the connecting body 13 can also be made separately.

In this joint, when the cam lever 24 is tilted as shown by the solid line in FIG. 6, the connecting body 13 compresses the spring 15 and moves, straddling both the casings 1 and 4.
Make them unrotatable. When the cam lever 24 is raised up as shown by the chain line, the force of the spring 15 causes the connecting body 1 to
3 separates from the casing 1, the casings 1 and 4 become unrotatable, and the positional relationship between the connecting pipes 19 and 20 can be changed as desired. In this example, when rotating the casings 1 and 4, the cam lever 24
All you have to do is stand up the connecting pipes 19 and 20.
It is easy to change the positional relationship between the two. and,
In this example as well, connecting pipe 1 with the required positional relationship
The relationship between 9 and 20 will not change unnecessarily.

FIG. 7 shows a third embodiment, which is biased toward the casing 4 by a spring 15 and partially inside the casing 1.
The part of the connecting body 13, the other part of which is located inside the casing 4, has a truncated cone shape with an inclined outer peripheral surface, and the locking protrusion 14 formed on the surface has a corrugated cross section. It's summery. The inner surface of the peripheral wall 5 of the casing 4 has the same slope as the connecting body 13, and the locking protrusion 12 has a corrugated cross section. The support shaft 8 is inserted from the casing 4 side, and the locking piece 10 at its tip is locked to a step formed on the inner surface of the support cylinder 7, so that the casings 1 and 4 are rotatably connected.

In this example, when changing the positional relationship of the connecting pipes 19 and 20, they are turned strongly in the required direction. Then, the locking protrusion 12 of the casing 4 engages the connecting body 1.
3 is moved against the force of a spring 15 to change the engagement state of the locking protrusions 12 and 14. In this example, the moving means of the connecting body 13 moves the connecting pipe 1
It's becoming 9,20. Unnecessary rotation of the casings 1 and 4 is caused by the strength of the spring 15 and the locking protrusions 12 and 1.
This is prevented by a depth of engagement of 4. In addition, since the locking protrusion 11 of the peripheral wall 2 is for making the connecting body 13 non-rotatable, in this example, excluding the locking protrusion 11, the outer peripheral cross section of the support tube 4 is square, and the connecting body 13 is
It is also possible to make the connecting body 13 non-rotatable by making the cross section of the hole at the center square.

Effects of the invention In the present invention, since the pair of casings 1 and 4 can be connected or released by the connecting body 13 slidably provided inside the casings 1 and 4, the positional relationship of the connecting rods provided in the casings 1 and 4 can be fixed or released. It is possible to change. Therefore, by connecting, for example, a rod-shaped handle of a cleaning tool with this, the angle between the tool and the handle can be changed according to the usage condition, making it possible to perform cleaning efficiently and reliably.
