Description

[Technical field]

[0001] The present invention relates to a fixture and a cooking appliance equipped with the fixture. [Background technology]

[0002] Jitsuto No. 3000622 (hereinafter referred to as Patent Document 1) describes a disk-shaped fastener that is fixed to a mounting surface such as a tile or glass surface. A protrusion that protrudes from the bottom surface is provided at the center of the bottom surface of the fastener. This protrusion forms a gap between the bottom surface of the fastener and the mounting surface, and this gap makes it easy to release the fastener from its adhesion to the mounting surface.

[0003] [Patent Document 1] Publication No. 3000622 Summary of the Invention [Problem to be solved by the invention]

[0004] Although the fixture in Patent Document 1 can easily release itself from adhesion to the mounting surface by the protrusions, the protrusions cause the periphery of the bottom of the fixture to float above the mounting surface. Therefore, when the fixture is attached to the mounting surface, the periphery of the fixture does not adhere evenly to the mounting surface, making it difficult to fix the fixture to the mounting surface.

[0005] Therefore, one object of the present invention is to provide a fastener that is easy to fasten to a mounting surface. [Means for solving the problem]

[0006] A fixture according to one solution of the present invention is a fixture fixed to a mounting surface, and includes a flat suction cup, a cup body that presses down on the suction cup from above, a lever attached to the top of the cup body for attaching and releasing the suction cup, and an operating shaft that moves the suction cup up and down in conjunction with the lever. The suction cup has protrusions on its top and bottom surfaces. Effect of the Invention

[0007] According to one solution of the present invention, a fastener that can be easily fixed to a mounting surface can be provided. [Brief description of the drawings]

[Diagram 2] FIG. 2 is an enlarged view of line AA' in FIG. [Diagram 3] FIG. [Figure 4] FIG. 4 is a cross-sectional view of the cooking device shown in FIG. [Diagram 5] 1 is a cross-sectional view showing a fixed state and an released state of the cooking appliance. BEST MODE FOR CARRYING OUT THEINVENTION

[0009] In the embodiments of the present invention, the description will be divided into a plurality of sections, etc., as necessary, but in principle, they are not unrelated to each other, and one is related to the other as a partial or complete modification, detail, etc. For this reason, in all the drawings, members having the same function are given the same reference numerals, and repeated description thereof will be omitted.

[0010] In addition, the number of components (including the number, numerical value, amount, range, etc.) is not limited to a specific number, and may be more or less than a specific number, unless otherwise specified or clearly limited in principle to a specific number. In addition, when referring to the shape of a component, etc., it includes things that are substantially similar or similar to that shape, etc., unless otherwise specified or clearly considered not to be the case in principle.

[0011] A fastener according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view of a fastener 10, where FIG. 1a shows the fastener in the released state and FIG. 1b shows the fastener in the fastened state. FIG. 2 is an enlarged view of the area between line A-A' in FIG. 1. The left-right direction in FIG. 1 will be described as the width direction of the fastener, and the up-down direction as the height direction of the fastener. The fastener 10 is used to fasten an object to a horizontal surface or to suspend an object from a vertical surface or ceiling. In the embodiment of the present invention, the fastener 10 will be described as being fastened to a horizontal surface (mounting surface S).

[0012] The fixture 10 has a cup body 13 and a lever 11 on the cup body 13 for fixing and releasing the fixture 10. The lever 11 is linked to an operating shaft 17 via a support shaft 18. When the lever 11 is rotated approximately 90 degrees in the vertical direction on the cup body 13, the linked operating shaft 17 can be displaced in the vertical direction. To specifically explain the movement of the lever 11 and the operating shaft 17 when the fixture 10 is fixed, the lever 11 is rotated downward around the support shaft 18. Then, the lever 11 becomes a force point. Also, the point where the lever 11 and the cup body 13 contact each other becomes a fulcrum. Then, the lever 11 can displace the operating shaft 17 linked to the lever 11 in the upward direction.

[0013] The fixture 10 also has a suction cup 20 at the tip of the operating shaft 17. A circular plate (not shown) is connected to the tip of the operating shaft 17, and a circular suction cup 20 made of, for example, resin rubber is provided around the periphery of the plate by insert molding. This allows the operating shaft 17 and the suction cup 20 to move in conjunction with each other. When the lever 11 is rotated downward, the operating shaft 17 is displaced upward, and the suction cup 20 is lifted from the center of the circle. The suction cup 20 is fixed to the attachment surface S by being pulled upward.

[0014] The spring 16 is wound around the operating shaft 17 and acts to easily displace the suction cup 20 from a fixed state to a released state. To be more specific, when the fixing of the fixture 10 is released, the operating shaft 17 displaces from the upper to the lower direction. Then, the spring 16 returns from the compressed state to its original state. Therefore, due to the action of the spring 16, the suction cup 20 easily displaces from a state in which it is pulled upward to a flat (plate-like) state.

[0015] The suction cup 20 has a rib 21 that protrudes upward. The rib 21 is provided on the periphery of the suction cup 20 so as to contact the edge 14 of the cup body 13. The length L1 of the rib 21 in the height direction is set so that the edge 14 of the cup body 13 and the rib 21 contact each other. The contact between the edge 14 of the cup body 13 and the rib 21 allows the fastener 10 to be stably placed on the mounting surface S. When the fastener 10 is fixed to the mounting surface S, the rib 21 acts to transmit a force transmitted from the cup body 13 in the direction of the mounting surface S to the protrusions 22 described below.

[0016] The width L2 of the rib 21 is set to be longer than the width of the edge 14 of the cup body 13. By setting the width L2 to be longer, the upper surface of the rib 21 can receive the downward pressing force transmitted from the edge 14 when the fastener 10 is fixed.

[0017] In addition, the suction cup 20 has a protrusion 22 on the periphery of its bottom surface. The protrusion 22 is provided below (directly below) the rib 21 with the suction cup 20 in between. The protrusion 22 is provided below the rib 21, and acts to transmit the force that presses the fastener 10 toward the mounting surface S through the rib 21 to the mounting surface S. The protrusion 22 is provided on the periphery of the bottom surface of the suction cup 20, and therefore the fastener 10 can be placed parallel to the mounting surface S. In other words, when the fastener 10 is placed, the protrusion 22 comes into contact with the mounting surface, and therefore a sealed space is easily formed between the suction cup 20 and the mounting surface S. To be more specific, when the lever 11 is rotated downward, a force is generated that presses the cup body 13 downward. This force presses the rib 21 toward the mounting surface S (downward) at the same time as the lever 11 is lowered, and therefore the downward force is also transmitted to the protrusion 22 formed on the back surface of the rib 21. Therefore, the protrusion 22 can be brought into close contact with the mounting surface S.

[0018] The width L3 of the protrusions 22 is longer than the width L2 of the ribs 21. When the suction cups 20 are fixed, they are displaced upward. At this time, since the width L3 of the protrusions 22 is longer than the width L2 of the ribs 21, the protrusions 22 are unlikely to be displaced upward. Therefore, when the fixing device 10 is fixed, even if the suction cups 20 are displaced upward, the protrusions 22, which are the periphery of the suction cups 20, continue to be in close contact with the mounting surface S. This makes it difficult for air to enter between the suction cups 20 and the mounting surface S (gap 24), which will be described later.

[0019] In addition, the suction cup 20 is provided with a protrusion 23 at the center of the bottom surface, which is the same height as the protrusion 22. When the lever 11 is rotated upward to release the fixing of the fixture 10, the operating shaft 17 is displaced downward, and the spring 16 is displaced from the compressed state to its original state. As a result, the suction cup 20 is displaced to a flat state. When the suction cup 20 returns to the flat state, the protrusion 23 comes into contact with the mounting surface S due to the action of the spring 16. The slight vibration caused by the protrusion 23 coming into contact with the mounting surface S makes it easier for the suction cup 20 to be released from the fixed state. In addition, when the operating shaft 17 is displaced downward, there is a risk that the operating shaft 17 will come into contact with the mounting surface S and cause scratches. However, the protrusion 23 covers the operating shaft 17, thereby preventing scratches on the mounting surface S.

[0020] When the fastener 10 is placed, the suction cup 20 has a gap 24 between the protrusions 22 and 23. Generally, by pressing the suction cup against the mounting surface, the volume between the mounting surface and the suction cup decreases. When the suction cup is pulled up in this state, the volume inside the suction cup increases. This reduces the density of the air inside the suction cup, and the pressure inside the suction cup decreases compared to the surrounding area. The suction cup is fixed to the mounting surface by the difference in atmospheric pressure between the inside of the suction cup and the area around the suction cup. The suction cup 20 has a gap 24 formed between the protrusions 22 and 23 when the fastener 10 is placed. When the lever 11 is rotated downward, the suction cup 20 is displaced upward. This reduces the density of the air in the gap 24. The suction cup 20 is fixed to the mounting surface S by the pressure in the gap 24 decreasing compared to the surrounding area.

[0021] When the suction cup 20 is fixed, the periphery of the suction cup 20 is in close contact with the mounting surface S, but the center of the circle of the suction cup 20 is easily displaced upward. To explain in detail, it is assumed that the suction cup 20 does not have the protrusions 22, 23. In this case, when the fixture 10 is placed, the suction cup 20 is in close contact with the mounting surface S because it is plate-shaped. When the suction cup 20 is in close contact with the mounting surface S, when the lever 11 is rotated downward, the lever 11 is difficult to rotate (the suction cup 20 is difficult to displace upward). However, the protrusions 22, 23 form a gap 24 between the bottom surface of the suction cup 20 and the mounting surface S. As a result, when the lever 11 is rotated downward, the suction cup 20 is easily displaced upward. In addition, the protrusions 22 press the periphery of the suction cup 20 toward the mounting surface S by the edge 14 of the cup body 13, so that the suction cup 20 is in close contact with the mounting surface S. As a result, the fixture 10 is easily fixed to the mounting surface S.

[0022] Hereinafter, as an example of use of the fixing device 10A of the present invention, the case where the fixing device 10A is used in a cooking device 30 will be described, but explanations that overlap with those of the first embodiment will be omitted. Fig. 3 is a perspective view of the cooking device 30, and Fig. 4 is a cross-sectional view of the cooking device 30. Fig. 5 is a cross-sectional view showing the fixed and released states of the cooking device 30, where Fig. 5a shows the released state and Fig. 5b shows the fixed state of the fixing device. The cooking device 30 has the fixing device 10A and is a tool that can cut pounded rice cakes to any size. The cooking device 30 is used by being fixed to a mounting surface S via the fixing device 10A.

[0023] Cooking device 30 is mainly composed of a hopper 32, a transfer section 40, and a base 34. Hopper 32 is used to store, for example, freshly pounded rice cakes, and is open at the top and bottom. Hopper 32 is formed in a mortar shape with the diameter gradually decreasing from the top to the bottom.

[0024] A transfer section 40 is provided below the hopper 32. The transfer section 40 has a guide tube 43, a cap 46, a cutter 48, and a rotating handle 47. The guide tube 43 is provided below the open hopper 32 and communicates with the hopper 32 so that the mochi contained in the hopper 32 can be transferred to the guide tube 43. A hemispherical cap 46 is provided at one end of the guide tube 43 to discharge the mochi moving inside the guide tube 43. The cap 46 is provided with a cutter 48 for cutting the mochi discharged from the cap 46. The guide tube 43 is provided with a spiral blade (not shown) for transferring the mochi contained therein to the cap 46. The other end of the guide tube 43 is provided with a rotating handle 47 for rotating the spiral blade.

[0025] The base 34 is provided below the transfer section 40 and is for supporting the cooking appliance 30. A fixing device 10A is provided inside the base 34. A lever 11A is exposed to the outside from an opening in the front of the base 34. The lever 11A can be used to fix and release the cooking appliance 30 by raising it upward from the support shaft 18A as a starting point and lowering it. A cup body 13A is provided below the lever 11A (inside the base 34). The fixing device 10A (cooking appliance 30) is pressed against the mounting surface S by lowering the lever 11A. An operating shaft 17A is connected to the lever 11A via the support shaft 18A at the tip. A suction cup 20A is provided at one end of the operating shaft 17A. The suction cup 20A is provided below the cup body 13A and is displaced by the vertical movement of the operating shaft 17A. The suction cup 20A is fixed to the attachment surface S by being pulled upward from the center of the circle.

[0026] In addition, the spring 16A is wound around the operating shaft 17A, and the spring 16A is displaced to its original state by displacing the operating shaft 17A downward. Since the spring 16A returns to its original state from its compressed state, the suction cup 20A can be easily displaced from a state in which it is pulled upward to a flat (plate-like) state.

[0027] Ribs 21A are provided on the periphery of the upper surface of suction cup 20A. Therefore, ribs 21 act to transmit the downward pressing force through cup body 13A to protrusions 22A on the bottom surface of suction cup 20A, which will be described later. Ribs 21A are also provided so as to come into contact with cup body 13A. By coming into contact with cup body 13A, ribs 21A allow cooking appliance 30 to be stably placed on mounting surface S.

[0028] The bottom surface of suction cup 20A has protrusion 23A. Protrusion 23A is provided at the same height as protrusion 22A. When lever 11A is rotated upward to release cooking appliance 30 (fixing device 10A), operating shaft 17A is displaced downward and spring 16A is displaced from its contracted state to its original state. As a result, suction cup 20A is displaced to a flat state. When suction cup 20A returns to its flat state, protrusion 23A comes into contact with mounting surface S due to the displacement of spring 16A. The slight vibration caused by protrusion 23A coming into contact with mounting surface S makes it easier to release suction cup 20A from its fixed state.

[0029] Next, a method for fixing cooking appliance 30 to mounting surface S will be described. First, cooking appliance 30 is placed on mounting surface S. At this time, since protrusions 22A and 23A are provided at the same height on the bottom surface of suction cup 20A, cooking appliance 30 can be stabilized. Furthermore, since edge 14A of cup body 13A and rib 21A are provided to contact each other, fixing device 10A can be stably placed. In other words, cooking appliance 30 can be stably placed.

[0030] Next, the user rotates the lever 11A downward to fix the cooking appliance 30 to the mounting surface S. Then, the operating shaft 17A linked to the lever 11A is displaced upward, and the suction cup 20A linked to the operating shaft 17A is also displaced upward. The suction cup 20A has protrusions 22A and 23A, so a gap 24A is formed. This gap 24A makes it easy for the center of the suction cup 20A to displace upward. In addition, when the user rotates the lever 11A downward, the cup body 13A is pressed toward the mounting surface S. The suction cup 20A has a rib 21A on its upper surface, so it acts to transmit the force transmitted from the edge 14A of the cup body 13A to the protrusion 22A. As a result, the cup body 13A is pressed downward and at the same time the protrusion 22A comes into close contact with the mounting surface S. This close contact makes it difficult for surrounding air to flow into the suction cup 20A. As the pressure inside the suction cup 20A decreases compared to the surroundings, the suction cup 20A is fixed to the attachment surface S. In other words, the cooking appliance 30 is fixed to the attachment surface S.

[0031] Next, a method for releasing the fixture 10A will be described. The user rotates the lever 11A upward. This causes the operating shaft 17A linked to the lever 11A to be displaced downward, and the suction cup 20A linked to the operating shaft 17A to be displaced downward as well. When the suction cup 20A is displaced, the spring 16A is displaced from its contracted state back to its original state. This makes it easy for the suction cup 20A to displace to a flat state. When the suction cup 20A is displaced, the protrusion 23A comes into contact with the mounting surface S. The slight vibration caused by the protrusion 23A coming into contact with the mounting surface S makes it easy for the suction cup 20A to be released from its fixed position.

[0032] The fixing devices 10 and 10A according to the present invention have been described above. Fixing device 10A has been described as being used in cooking device 30 for cutting pounded rice cakes to arbitrary sizes, but the present invention is not limited to this and fixing device 10A may also be used in vibrating equipment (for example, a mixer or a kneader for kneading dough). Furthermore, the present invention is not limited to the above-described embodiment and may be modified within the scope of the gist of the present invention. [Explanation of symbols]
