Description

  The present invention relates to a connection panel in which at least two panels are rotatably connected, as represented by a cooking oil remover formed by rotatably connecting panels.

  Conventionally, as a cooking oil eliminator, a panel in which adjacent panels are pivotally connected by inserting a shaft portion of a U-shaped pin into each edge winding (also called curling or ear winding) formed on the side edge thereof is known. (Patent Documents 1 and 2, etc.). According to this configuration, the cooking oil remover can be used with an appropriate angle between the panels depending on the installation environment. Further, when not in use, the panel can be folded and stored in a stacked state.

  As another connection structure, a hinge is also known (Patent Document 3). However, in this configuration, since the panel is connected by a single pin, the edges of each other interfere when folded. Panels cannot be completely overlapped.

  As described above, the panels connected by the U-shaped pins can be in a state where the panels are completely overlapped when not in use, and the configuration is simpler and easier to assemble than the hinge. Although there is an advantage, there is a problem that the U-shaped pin is easily removed.

  In other words, each of the pair of left and right shaft portions of the U-shaped pin is formed with a diameter smaller than the inner diameter of the edge winding, thereby connecting the panels so as to be rotatable, but between the shaft portion and the edge winding. Since a gap is generated, the U-shaped pin is easily removed.

  Some of them are designed so that the U-shaped pins can be inserted and removed intentionally in order to enable assembly and disassembly by the user.

  On the other hand, it is conceivable that the U-shaped pin portion has a diameter equal to or larger than the inner diameter of the edge winding, and the U-shaped pin is forcibly fitted to the edge winding so that it cannot be removed. Another problem arises in that it cannot be performed or the edge winding or the panel is distorted by an excessive rotation of the panel.

  The present invention has been made in order to solve the above-described problems, and an object of the present invention is to provide a connection panel in which at least two panels are rotatably connected and the connection pin does not come out of the pin hole. Is to provide.

  In order to achieve the above-described object, in the present invention, a pin hole is formed in each panel to be connected, and a substantially U-shaped connection pin that connects the panels relatively rotatably with the pin holes in parallel. The connecting pin has a pin body in which two pivot portions are formed in parallel at a predetermined interval, and has an outer diameter that has elasticity to expand and contract in the radial direction and can be press-fitted into the pin hole. An elastic sleeve having an inner diameter after press-fitting is larger than the outer shape of the pivot portion, and a stopper of the elastic sleeve provided at one end of the pivot portion into which the elastic sleeve is inserted in advance.

  The connecting pin of the present invention is assembled by inserting the elastic sleeve into the pin hole of the member to be connected, in which the elastic sleeve is inserted in the pivot portion in a state of being prevented from coming off. This press-fitting prevents the connecting pin from inadvertently coming out of the pin hole. In addition, since the pivot part is rotatable within the elastic sleeve after the press-fitting, the panels can be connected relatively rotatably.

  In terms of molding, the pin body is preferably one steel material bent into a substantially U shape, and the retaining member is preferably a caulking process of the steel material.

  In addition, it is easy to use a spring pin for the elastic sleeve, and even if the pin hole is a screw hole, it can be press-fitted without being removed. Among them, there is a roll pin in which slits are formed in the axial direction. In this case, there is an advantage that roundness is high and there is little settling. In addition, after press-fitting into the pin hole, the entire circumferential surface comes into contact with the hole, so that the connecting pin can be more reliably prevented from coming off from the pin hole.

  In addition, if the slit of a roll pin is a waveform, intertwining of the said roll pins will decrease in the manufacture stage of a connection pin.

  On the other hand, the elastic sleeve may be a spy roll pin, which is another spring pin, which is a metal plate having a spring property rounded into a cylindrical shape. In this case, the entire outer periphery of the pin has elasticity, and vibration or impact There is a merit that it is strong.

  Furthermore, it is preferable that the elastic sleeve has a chamfered portion at least on the press-fitting side. This is because chamfering (tapered end) can smoothly press fit into the pin hole.

  The panel to be connected is arbitrary, but a panel having the same configuration can be connected to the left and right as long as the edge is provided with pin holes at the top and bottom.

  As a most suitable application example of the connection panel, there is a cooking oil dispenser in which a plurality of metal panels having edge windings formed on the side edges are connected by connection pins using the edge windings as pin holes.

  According to the present invention, the connected panels can be smoothly rotated with a light force, and the connecting pins are not accidentally pulled out from the pin holes. Therefore, the operability and reliability of the connection panel can be improved.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows cooking oil eliminator according to an embodiment of the present invention. This cooking oil eliminator is obtained by rotatably connecting four metal panels P by a substantially U-shaped connecting pin J described later.

  Each panel P forms an edge winding R by curling the periphery. Of these, the panels P are connected using the right and left edge windings R, and connecting pins J described later are inserted into the left and right edge windings R from above and below.

  Note that an uneven portion F is formed on the surface of the panel P. Although this uneven | corrugated | grooved part F raises the plate | board surface intensity | strength of the panel P on a structure, it becomes a pattern in design.

  FIG. 2 is an enlarged view of a portion surrounded by a one-dot chain line circle in FIG. The other connecting portions have the same configuration, and the connecting pin J is a substantially U-shaped (inverted in the drawing) pin body 1 with the vertical edge winding R of the panel P as a pin hole, Two sets of elastic sleeves 2 that are press-fitted into the edge winding R and a retaining member 3 are provided.

  FIG. 3 shows the details of the connecting pin J. The pin body 1 is formed by bending a round bar-shaped steel material into a U-shape and paralleling two pivot portions 1b on the left and right sides of the curved portion 1a. It is provided. The elastic sleeve 2 is made of a cylindrical member provided with slits 2a in the axial direction, and has elasticity to expand and contract in the radial direction. Further, a chamfer 2b is provided at the end. In addition, the slit 2a is a waveform in this embodiment, and more specifically, a roll pin belonging to a spring pin is employed. The stopper 3 is formed by caulking the end of the pivot 1b after the elastic sleeve 2 is inserted.

  As for the dimensions of each part, the outer diameter (diameter) of the pivot part 1 b is smaller than the inner diameter of the elastic sleeve 2. This is the same relationship after the elastic sleeve 2 is press-fitted into the edge winding R, as will be described later. In other words, there is always a certain gap between the pivot 1b and the elastic sleeve 2, so that the elastic sleeve 2 (the panel P into which it is press-fitted) can rotate 360 degrees about the pivot 1b. The retainer 3 (the maximum dimension thereof) is larger than the inner diameter of the elastic sleeve 2 before press-fitting, and always holds the elastic sleeve 2 on the pivot 1b.

  On the other hand, the outer diameter of the elastic sleeve 2 before press-fitting is larger than the inner diameter of the edge winding R. Therefore, when the elastic sleeve 2 is press-fitted into the edge winding R, the elastic sleeve 2 is reduced in diameter by narrowing the clearance of the slit 2a.

  FIG. 4 shows the manufacturing process of the connecting pin J. First, a steel bar having an appropriate thickness and length is bent into a U shape (FIG. 4A), and a pair of pivot portions 1b parallel to the left and right are formed. Then, the elastic sleeve 2 is inserted into each of the pivot portions 1b (FIG. 10 (c)), and finally, the stopper 3 is provided at the end of the pivot portion 1b to complete the connecting pin J. To do.

  In order to assemble the connection pin J having such a configuration to the panel P, as shown in FIG. 5, the edge windings R of the adjacent panels P are placed in parallel, and the elastic sleeve 2 is press-fitted into each edge winding R. Since the chamfer 3b is formed at the end of the elastic sleeve 2, smooth press-fitting is possible. By this press-fitting, the elastic sleeve 2 is reduced in diameter in the edge winding R. Thereafter, the outer peripheral surface is pressed against the edge winding R due to the repulsive force, and the elastic sleeve 2 comes out of the edge winding R carelessly. There is nothing.

  Each panel P can be rotated in the entire range of 360 degrees with the pivot portion 1b of the pin body 1 as a rotation axis without the mutual interference of the panels P. Therefore, when used, each panel P can be placed in an angled state as shown in FIG. 1, and when not in use, the four panels P are flattened as shown in FIG. It is possible to superimpose.

  In addition, this invention is not limited to embodiment mentioned above, The number of the panels P of the cooking oil removal is arbitrary. Further, the object of connection is not limited to the panel P having the edge winding R, and other panels may be used as long as they have pin holes and are connected in parallel with the pin holes.

  Further, for the connecting pin J, the elastic sleeve 2 is a spy roll pin in which the roll pin of the linear slit shown in FIG. 7 and the spring plate material shown in FIG. In addition, the retainer 3 is not limited to the above-described shredding process, and as shown in FIG. 9, a through pin 4 is provided on the pivot 1b, or this part is melted or a melted one is attached. Thus, an outer portion larger than the inner diameter of the elastic sleeve 2 may be formed.
