Description

[Detailed explanation of the invention] [Technical field in which it is used] This invention is a tool with a handle used in ordinary households.
That is, mainly a spatula for stirring the hot water in the bathtub,
Related to handles such as brushes with handles for cleaning bathrooms, toilet bowls, etc.

[Prior art and problems]

Conventionally, the handle of this type of tool has been fixed at a right angle or at a constant inclination angle to the center of the acting part that acts on the object, i.e., the brush body or the stirring plate, as shown in Figures 7 and 8. installed on.

However, there are times when it is easier to handle the tool if the action part is positioned along the surface of the object, or when the tool is hung on a hook such as a wall when not in use, the action part is placed perpendicular to the handle. It takes up a lot of space, gets in the way in narrow bathrooms and toilets, is bulky to package as a product, requires extra packaging materials, and takes up space for storage and transportation.

[Problems to be Solved] The purpose of this invention is to make the handle of the above-mentioned tool straight and bendable.

[Means to solve problems]

In this invention, the handle attachment base and the joint part of the handle are formed with a joint surface inclined at 45 degrees with respect to the axis of the handle,
At the center of these joint surfaces, both the front handle mounting base and the handle are rotatably connected by a pivot in a direction perpendicular to these joint surfaces, and at right angles to the position where the axes of these two members are aligned. The problem has been solved by providing a household tool with a folding handle characterized by having a click mechanism that locks at at least two positions.

[How to use and action]

First, when the axis of the handle attachment base, which is fixed to the brush body or stirring plate, is aligned with the axis of the handle, the two are fixed by the click mechanism and will remain in that state within the range of normal usage. For example, in the case of a brush for cleaning bathtubs and bathrooms, the bottom of the bathtub, the bathroom floor, the ceiling, etc. can be easily cleaned. Also, when using it as a spatula for stirring hot water, the handle and stirring plate are held at right angles, so place the stirring plate in the bathtub and move the handle up and down in the axial direction, just like a regular spatula. Can be used.

Also, from the state where the handle mounting base and the handle are in a straight line,
When the handle mounting base and the handle are rotated 180° around the pivot axis with a force stronger than the locking force of the click mechanism, they are re-engaged by the click mechanism when they are bent 90° relative to each other. To explain using the above example, the handle and the brush surface or stirring plate are parallel.

When using the brush in this state, you can clean the wall surface and the inner wall surface of the bathtub.

Also, when not in use, it engages with a hanging hook provided on the wall in the bathroom. It is also packaged in this state when it is sold, stored, and transported as a product.

〔effect〕

In this invention, the handle can be changed at least between a position where the handle is in a straight line and a position perpendicular to the axis of the handle attachment base of the action part consisting of a brush, stirring plate, etc.
It is locked at this position by the click mechanism, so
It can be used stably in any state, and when the handle is bent at right angles, it is not bulky and does not get in the way even in narrow bathrooms or toilets. In this folded state, products can be packaged for storage, sale, and transportation without being bulky, saving packaging materials and reducing storage and transportation costs. Furthermore, the structure is simple and there is almost no risk of failure or damage.

[Embodiment]

In order to facilitate understanding of this invention, a description will now be given based on a representative embodiment shown in the drawings.

Embodiment 1 The boiling rod shown in FIGS. 1 to 5 will be explained.

Reference numeral 10 designates a stirring plate as an action part, and it is generally made of a synthetic resin molded product. An inclined surface 12 inclined at 45 degrees with respect to the central axis O ₁ is formed on this upper surface, and an inclined surface 12 is formed at the center of this inclined surface 12 at right angles to this surface, that is, at an angle of 45 degrees with respect to the central axis O ₁ . A pivot bearing hole 13 with an inclined axis O ₃ is drilled.

Reference numeral 14 denotes a handle that is a separate member from the stirring plate, and in the illustrated example, it consists of a connecting member 14a and a handle body 14b screwed onto the handle, and the end of the connecting member 14a is aligned with the axis O ₂ of the handle. On the other hand, it has an inclined end surface 15 inclined at an angle of 45 degrees, and the interior thereof is a cavity 24. A pivot hole 16 is bored in the center of the inclined end surface 15 in a direction perpendicular thereto. 1
The shape of 6 is an occluded circle shape in which the top and bottom are parallel and notched in the chord direction, and the radius of the circular arc portion is equal to the radius of the pivot bearing hole 13 of the stirring plate 10.

17 is a pivot for pivotally connecting the handle attachment base 11 of the stirring plate 10 and the connecting member 14a which is a part of the handle, and the cross-sectional shape of the shaft 18 is similar to the pivot hole 1.
6 (see FIGS. 2, 3, and 4), and one end of the pivot 17 has a large-diameter head 19 that is almost similar in shape to the shaft 18. The length of the shaft portion 18 is the same as that of the inclined surface 12 of the two members.
and a wall surface forming the inclined end surface 15, and has a length sufficient to insert the leaf spring 20 to prevent it from coming off in the diametrical direction, and the insertion hole 21 of the leaf spring 20 is inserted into the shaft portion. 18 is bored in the diametrical direction near the tip.

The plate spring 20 has a rectangular cross-sectional shape that can be inserted into the insertion hole 21, and is slightly curved.

Therefore, the inclined surface 12 of the handle attachment base 11 of the stirring plate 10 and the inclined end surface 15 of the handle are abutted against each other, and these two members are pivotally connected by the pivot shaft 17.
Insertion receiving hole 1 for the pivot shaft 17 that further protrudes from the two members
3 and the pivot hole 16, and the resilient force of the leaf spring 20 brings the two inclined surfaces 12 and 15 into pressure contact to form a common joint surface.

Therefore, in this invention, the handle attachment portion 1
1 and a connecting member 14a which is a part of the handle, a click mechanism is provided between the axis _O1 of the handle attachment part 11 and
The position of the axis O ₂ of the handle in a straight line and these axes
O ₁ and O ₂ can be locked at right angle positions, and the click mechanism shown in the figure has a hemispherical or circular shape on the inclined surface 12 around the pivot bearing hole 13 at a 180° phase difference. A pair of projections 22 having a shape of
Hemispherical or trough-like recesses 23 that engage with the leaf springs 2 are provided with a phase difference of 180°, and cooperate with the leaf spring 20 to form a click mechanism.

The positions of the protrusion 22 and the recess 23 described above are relative, and even if the provided members are opposite to those shown in the drawings, the invention remains the same.

In addition, in the illustrated example, the leaf spring 20 is
In the cavity of the connecting member 14a which is a part of 4,
The connecting member 1 is inserted into the insertion hole 21 of the pivot 17.
By screwing the handle body 14b onto the handle body 4a, the leaf spring 20 is prevented from being removed at the end face of the handle body 14b.

Each member other than the stirring plate 10 described above is also made of a synthetic resin molded product, and the leaf spring 20 may be made of a metal material such as a spring steel plate or phosphor bronze, but is preferably made of an elastic synthetic resin material such as polycarbonate resin.

Effects of Embodiment 1 In this embodiment, the invention not only works, but also allows the pair of protrusions 22 to fit into the pair of depressions 23 when the axes O ₁ and O ₂ are located in a straight line. Since this state is maintained by the leaf spring 20, the stirring plate 10 and handle 14 do not rotate around the pivot 17, that is, around this axis _O3 .

Also, a stirring plate 10 and a handle 14 are arranged around the axis _O3 .
When a large twisting force is applied to these in order to relatively rotate them by 180 degrees, the leaf spring 20 is deformed against the elastic force of the leaf spring 20, and the pair of protrusions 22 are disengaged from the pair of depressions 23 and the pair of protrusions 22 are separated from the pair of depressions 23. The protrusion 22 has an inclined end surface 15
It slides in an arc while being pressed against the surface, and when it has rotated 180 degrees, it is again fitted into the pair of depressions 23 and fixed.

In this embodiment, each member can be assembled and disassembled.

Effects of Embodiment 1 In this example, since the external click mechanism that produces the effects of this invention is as described above, the structure is simple, the operation is easy, and the leaf spring 20 is confined in the cavity of the connecting member 14a. There is no risk of it falling off.

Additionally, items made entirely of synthetic resin do not have the risk of rusting, making them ideal for use as household tools that can be placed in or washed with water.

In addition, in this embodiment, the cross-sectional shape of the pivot shaft 17 is made into an occluded circular shape as shown in the figure, and the pivot hole 16, which is a part of the handle 14, is also shaped so as to fit into the pivot hole 16. Since the leaf spring does not rotate around the axis _O3 and can simply move in the axial direction by the height of the protrusion 22, the leaf spring is connected to the connecting member 14a.
Within the cavity, the deformation is only a slight change in the degree of curvature, and its position does not move at all.
The plate spring 20 is stable, and only an external force acts on it when changing the angle of the handle 14, and almost no external force acts on it thereafter, so there is no risk of the plate spring 20 becoming fatigued and breaking.

In the above example, the pivot 17 was inserted from the handle attachment part 11 side of the stirring plate 10, and the leaf spring was inserted into the cavity of the connecting member 14a. The leaf spring 20 may be inserted into the insertion hole 21 at the lower surface on the mounting portion 11 side.

Alternatively, the pivot 17 may be formed integrally with either the inclined surface 12 or the inclined end surface 15 and protrude from these surfaces at right angles toward the other member, and this also falls within the scope of this invention.

Example 2 A brush 25 is used as the action part in place of the stirring plate 10 of Example 1, and the other configurations are the same, so explanations of the structure and effects will be omitted.

In the above example, the click mechanism was described as being locked when rotated 180 degrees around the axis 17, but even if the click mechanism could be locked every 90 degrees, the invention is the same, and the above-mentioned click mechanism If it is a mechanism, the same effect can be achieved even if the protrusions 22 and depressions 23 are provided at 90° angle intervals.
