Description

[Detailed Description of the Invention] The present invention relates to a pivot structure for a single-swing door body used in refrigerators and homes, and is completely capable of opening the door body to either the left or right side. . 5 An example of winding the present invention will be described below based on illustrative drawings. In Figures 1 and 2, 1 is the door body, 21% 2b
are the upper and lower parts of the door pivot body. 3% 4 is a handle pivoted near both left and right sides of the front face of the door body 1 so as to be able to swing up and down with a rotation shaft 6.6 (a 7a% 7m) and 81L
%81) is a rotation center vertical axis provided at two locations, upper and lower, on both left and right sides of the door body 1.

As shown in FIGS. 3 to 5, upper and lower vertical axes 7a and 7b% and 8a and 8bij on the same side are arranged concentrically, are supported movably up and down by fixed guides 9.10, and are fixed By the compression coil spring 12 interposed between the guide 10 and the seven flange 11 of the vertical shafts 71 to 8b,
7. The flange 11 is kept in an extended state in which it abuts the fixed guide 9, that is, in a state in which the tips of the vertical shafts 7a to 8b protrude from both upper and lower sides of the door body 1. 13 is the vertical axis 71-8b
It is a bearing member into which the leading end is relatively rotatably fitted, and is positioned at the same level as the upper part 2a and lower part 2b of the door pivot body.

The fixed guide 9 disposed on the lower side of the door body 1 and the bearing member 13 provided on the lower part 2b of the main body 1 are in contact with each other in an upper and lower relationship, and the bearing member 13 provided on the lower part 2b of the main body 13 is configured to receive and stop the door body 1 via a fixed guide 9 on the lower side of the door body.

i4a, 15a are L-shaped levers whose bent portions are pivotally connected to the door body 1 with shafts 16, and their lateral ends 17 are placed on the bins 18 protruding near the lower ends of the vertical shafts 7a, ga. are in contact. 19ti is a stopper for the L-shaped bars 141L and 151L.

141)%15m) is the rotating shaft 5 to which the handle 3.4 is fixed.
．． It is an L-shaped lever with a bent portion fixed to 6, the horizontal end 20 of which is located below a pin 21 protruding near the upper end of the vertical shafts 7b, 8b, and is supported by a tension coil spring 22.
The lateral end 20 is biased away from the bin 21. A long hole 23 is provided at the upper end of this L-shaped bar 141) 4151), and a bottle 24 is provided protruding from the lower end of the L-shaped lever 14abl+b located above.
is loosely fitted into the elongated hole 23.

According to the above configuration, when the door body 1 is in the closed state, the vertical shafts 71 to 8b of the left and right upper and lower metal parts protrude from both upper and lower sides of the door body 1, and the vertical axes 71 to 8b of the upper and lower parts of the door body 1 protrude from the upper and lower sides of the door body 1, and the vertical shafts 71 to 8b of the upper and lower parts of the main body are inserted into the bearing members 13 of the upper part 21L and the lower part 2b. Since the door body 1 is fitted into the door body 1, the door body 1 is locked in the closed state. The door body 1 in this state is moved to the left vertical axis 7a.
, 7b to the left, as shown in the right half of FIG. Rotate counterclockwise against the tension coil spring 22. As a result,
The horizontal end 92G of the lever 15b lifts the lower right vertical shaft 8b through the bin 21 against the compression coil spring 12, and the vertical shaft 8b is extracted upward from the bearing member 13 of the lower part 2b of the main body. . On the other hand, the rotation of the L-shaped bar 16b is caused by the rotation of the upper L-shaped bar 16b through the elongated hole 23 and the bottle 24.
The speed is transmitted to K, and this L-shaped bar 15! L rotates clockwise, and its lateral end 17 pulls down the upper right-hand flower vertical axis Ba against the compression coil spring 12 through the pin 18, so that it is also removed from the bearing member 13 of the upper part 2a of the main body. vertical axis 8
A will be pulled out downward.

Therefore, the door body 1 is
By pulling toward you, the left vertical axis of up and down 71L%7m
) and the main body side bearing member 13, the door body 1 can be opened to the left around the left vertical axis 78%7m).

When closing the opened door body 1, when you release your hand from the handle 4, the L-shaped lever 15a%1 is activated by the tension coil spring 22.
5t) is rotated back to the original position U where it contacts the stopper 19, and at the same time the right vertical shaft 8''s8b on the upper and lower sides is automatically returned to the extended position by the compression coil spring 12. Even in this state, the door body 1 can be closed. As shown in FIG. 4, vertical shafts 7a to 6b, which are at the maximum angle, are installed on the front side of the bearing members 13 of the upper part 2a and lower part 2b of the main body so that the bearing members 13 can be automatically locked.
It is desirable to have an inclined guide surface 13 & that is retracted against the compression coil spring 12 and guided to the hole of the bearing member 13 as the rest w1 is attached. However, as the door body 1 closes, the lower fixed guide 9 of the door body 1 rides up on the bearing member 13 of the lower body part 2b (on the rotation center side, both of these 13.8 rotate relative to each other in a vertically overlapping state), but this riding on the inclined guide surface 1
3a, the inclined guide surface 13& of the bearing member 13 of the lower part 2b of the main body is made wide iR, or the end edge that first comes into contact when the bearing member 13.90 runs over the body (Fig. 4) At least one of the portions 13t) and 9a) may be formed into an inclined surface or a curved surface.

When the door body 1 is moved to the right around the right-hand upper and lower vertical shafts 8a and gb using the relative rotation between the right-hand upper and lower vertical shafts 8a and 8b and the bearing member 13 fitted thereto, , just rotate the left handle 3 downward and pull it toward you.

In this case, the upper and lower left vertical shafts 7m and 7b are extracted from the bearing member 13.

The door body 1 can be removed from the main body by rotating both the left and right handles 3.4 downward, but from a safety standpoint, it is recommended to select both handles 3.4 to avoid this situation. It can be configured so that it can only be operated once. For example, the third
As shown in the figure and @5 figure, the left and right lever 141L,
A slide rod 26 supported laterally by a support member 25 is disposed between the downward ends of the vertical shafts 8a, and one of the wedge-shaped levers, e.g.
When the slide rod 26 is rotated to the pull-out position, the slide rod 26 is pushed by the lever 151 and moves laterally to the left, so as to prevent the other L-shaped bar 14a from rotating in the direction of pulling down the vertical shaft 7a. , can be configured.

In addition, in the above embodiment, the handle 3 for opening and closing the door body 1 is
．． 4 is also used as an operating tool for vertically moving the vertical shafts 7a to 8b, but a fixed handle may also be used as an operating tool for vertically moving the vertical shafts 7a to 8b, such as a lever type or a push button type. Of course, in either case, the direction of operation movement of the operating tool is not limited to the vertical direction as in the embodiment.

The present invention can be implemented and used as described above, and can be rotated to either the left or right side while opening one side with the body. The door body can be opened and moved in a convenient direction depending on the location and the dominant hand of the operator. Furthermore, when opening to either the left or right side, the pivot side is safely pivoted to the door pivot body in the same manner as a conventional single-swing door, and there is no fear of unexpected movement of the door body. or,
The pivoting means also serves as the locking means for locking the door body in the closed state, so there is no need to provide a separate locking means.

In particular, as shown in the embodiment, a vertical axis of rotation that can be freely inserted into and removed from a bearing member provided on the pivoting body of the door body in the vertical axis direction and a handle are provided on both the left and right sides of the door body. set, right,
The side handle or the operating tool attached to it and the vertical axis of the rotation center on the right side, and the handle on the left side or the operating tool attached to it and the vertical axis of the rotation center on the left side, respectively, to the operating movement of the handle or operation^. When interlocking means is provided to interlock each other so that the rotation center vertical shaft is pulled out from the bearing member, not only can the opening operation of the door body be performed in exactly the same way as a conventional single-swing door, but also the door It is only necessary to fix the bearing member on the side of the body pivoting body, and the door body pivoting body located around the door body can be configured simply and compactly like the conventional one.
