Abstract

<P>PROBLEM TO BE SOLVED: To solve such problems that a stirring member for a mixer generally used for industrial application is not yet satisfactorily developed in its structure, and for example, a stirring blade is dangerous in transportation after use, and is difficult to store due to a large space required for storage, etc. <P>SOLUTION: Blades, stirring members, in an electric stirrer have a collapsible constitution, which improves convenience in transportation, and storage characteristics when being stored. Specifically, in the mixer comprising an electric tool body portion, an impeller member for stirring, and a connecting member joining them, a blade member for stirring is formed collapsibly. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

    The present invention relates to a stirring mixer stirring member such as a stirring blade mainly used in a stirring blade portion of a mixer.

In general, agitators are used for industrial use when a small amount of mortar or ready-mixed concrete is agitated, and it has become widespread that the work is carried out with an electric mixer. Many manufacturers are working on various improvements. As an example, Japanese Patent Application Laid-Open No. 2003-144886 also discloses that a blade-like blade portion is bent halfway (note: not folding) to increase the stirring efficiency.
JP 2003-144886 A

  However, the publication of the above publication focuses on increasing the stirring efficiency, and is merely an application in consideration of the efficiency at the time of operation of the mixer. In addition, a stirring blade attached to a conventional mixer (according to its shape, the stirring member will be referred to as a stirring blade) is circular when viewed from the front as a single stirring blade. Since there are many things, the outer diameter had to be increased sufficiently to fulfill the function. There was also a functional approach during operation of the mixer to increase the stirring efficiency for blade-shaped stirring blades, but paying attention to the size of the stirring blades, carrying around when the mixer was stopped and stirring when storing There was a problem that a wasteful storage space was required because the blades were in the way. A typical stirrer is shown in FIG. 4, and the tool tip 102 is a conventional stirring blade. The stirring effect is obtained by the rotation of the stirring blade.

  Then, in view of said subject, this invention improves the convenience at the time of carrying and storage at the time of a mixer stop, and it aims at providing the stirring blade for mixers which can be at the time of carrying and storage.

  According to a first aspect of the present invention, there is provided an electric mixer including a power tool main body portion, a stirring blade member, and a connecting member for rotatably connecting the stirring blade member to the power tool main body portion. Is a stirring member for a mixer, which is formed so as to be foldable.

  The invention according to claim 2 is the mixer agitating member according to claim 1, wherein the mixer agitating member is bent by a hinge at the folding position.

  The invention according to claim 3 is configured such that the hinge at the folding portion is configured to keep the stirring blade member in an open state or a folded state by a spring material as a constituent member thereof. It is a stirring member for mixers of description.

  The invention according to claim 4 is the stirring member for a mixer according to claim 1, wherein the stirring member is formed in a stirring blade shape or an impeller shape.

  The invention according to claim 5 is the stirring member for a mixer according to any one of claims 1 to 4, characterized in that when the stirring blade member is in a folded state, the stirring blade member is covered with a lid that matches the folded shape. is there.

  The invention according to claim 6 is an agitating member for a mixer according to claims 1 to 5, which is used for a power tool for agitation such as concrete and mortar for industrial use.

  In the stirring member for a mixer according to the first aspect of the present invention, the storage space when not in use is reduced, and the space for carrying and storing is reduced.

  In the stirring member for a mixer according to the second aspect of the present invention, the folding portion can be kept open by a simple hinge, so that the cost is relatively lower than the cost of folding the blades by other methods.

  In the stirring member for a mixer according to the third aspect of the present invention, the spring can be opened by a spring during actual stirring, and can be used in a folded state by being locked when not stirring.

  In the mixer stirring member of the invention according to claim 4, the mixer stirring member of the present invention can be applied to shapes formed in various stirring blade shapes or impeller shapes.

  In the mixer stirring member according to the fifth aspect of the present invention, the risk of injury due to the edge during carrying is eliminated by this structure, and the edge is not damaged even during storage.

  In the mixer stirring member according to the sixth aspect of the invention, the mixer stirring member of the present invention is put on the market as an actual product in these applications.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a front view of a stirring member for a mixer according to the present invention, which is a stirring blade 1 composed of three blades. When used, the stirring blade 1 is in an open state as shown in FIG. 1, and after use, at the joint 2 of each blade as shown in FIG. 2, which is a side view of the stirring member for a mixer of the present invention, the arrow a , B, and c, respectively. Then, after folding, it becomes a shape as shown in FIG. 3 showing the state after folding according to the present invention, and is in a compact state.

  If it covers with the cover body which fits the shape of the stirring blade 1 of such a state, there will be no danger when carrying and space will not be taken also at the time of accommodation.

  In this embodiment, a three-blade stirring blade is taken up. However, the shape of the impeller is not limited to the shape of an impeller, and the same effect can be expected even with an impeller shape. However, any number of sheets may be used as long as they can actually be used.

  The present invention exhibits an unprecedented convenience when the mixer stirring member is stopped.

The front view of the stirring member for mixers of this invention. The side view of the stirring member for mixers of this invention. The figure which shows the state after the folding of this invention. The figure which shows the conventional typical stirrer.
