Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a door pivoting device that can be used to pivot the doors of various types of furniture so that they can be opened to either the left or right side.

(Prior art) A typical single-swing door is pivoted so that either the left or right sides can rotate, so it can only be closed in one direction. .

For such a general single-swing door, a device that pivots so that the door can be opened in either the left or right direction has been considered, but the conventional door pivot device of this type is A vertical bin pivotably mounted on both the left and right sides of the door is configured to be removable from the bearing, and by operating either one of the operating levers provided on the left and right sides of the door, It was configured to allow the vertical bin to be extracted from the bearing.

(Problems to be Solved by the Invention) In the conventional door pivoting device as described above, an operating lever is required to pull out the vertical bin on the other side without seeing through both the left and right sides of the door. It was not possible to use a door that had a simple fixed handle instead of an operating lever, or a handle of any design. Of course, before opening the door, one of the vertical pins must be pulled out by operating the operating lever, making it difficult to open the door easily and smoothly.

(Means for Solving the Problems) The present invention has been made to solve the above-mentioned problems, and its characteristics are as follows: One of the right and left sides is provided with a rotation center member, and the other side is provided with a pivoting means for relatively rotatably holding the rotation center member, and the left and right pivot means are provided with a rotation center member for holding the rotation center member on the other side. In addition to providing a movable holding member that opens and closes as the moving center member is withdrawn and the rotating center member enters, the movable holding members on both left and right sides are selectively opened, and both are prevented from opening at the same time. The point is that we have put in place a means to prevent this.

(Function) In the door pivot device configured as described above, the movable holding members in both the left and right pivot devices are prevented from opening at the same time by the check means, so both the left and right sides of the door are prevented from opening at the same time. Even if the sides are pulled toward the front at the same time, there is no risk that the rotation center member will be pulled out from both the left and right pivoting means and the door will come off. However, when the door is opened by pulling either the left or right sides towards you, the pivoting center member held by the pivoting means on the opening side is moved away from the pivoting means while opening the movable holding member. When pulled out, the other rotation center member becomes the rotation center of the opening door while being held by the movable holding member in the pivoting means.

(Example) An example of the present invention will be described below based on the attached illustrative drawings.

In FIG. 1, 1 is a door, and a pair of left and right vertical rotation center members 2a, 2b and 3a, 3 are provided at both upper and lower ends, respectively.

Pivot means 7a, 7b provided on the furniture main body 9 side at four positions corresponding to each of the rotation center members 2a to 3b allow the cylindrical shaft portions 10 of the rotation center members 2a to 3b to move in and out. A fixed guide plate 16 having a U-shaped recess 15 to which it fits, a fixed holding member 18 having a free hole-shaped recess 17 into which the flat shaft portions 11 of the rotational center members 2a to 3b fit in such a manner that they can move in and out, and a movable guide plate 16. A holding member 19 is provided. The fixed guide plate 16
The fixing and holding member 18 is composed of upper and lower protruding plate parts of a plate bent in a U-shape, and the attachment is attached to the vertical plate part between the two protruding plate parts via the roots 20. It is attached to the furniture body 9. The movable holding member 19 is pivotably mounted on a vertical shaft 21 at a position adjacent to the fixed guide plate 16 between the fixed guide plate 16 and the fixed holding member 18 so as to be horizontally swingable. cylindrical shaft portion 10 of
It has a recess 22 into which the movable holding member 19 is fitted, and is biased by a plate spring 25 interposed between a support shaft 23 protruding from the movable holding member 19 and a fixed support shaft 24.

Movable holding member 1 in a pair of left and right pivoting means 7a, 7b
As shown in FIG.
It is composed of wires 26a and 26b whose one ends are connected via wires 26a and 26b, and a connector 27 which connects both wires 26a and 26b in a state that allows relative movement within a certain range.

This connector 27 includes a removal prevention member 28 fixed to the free end of one wire 26a, and a frame-shaped member loosely fitted to the wire 26a so as to be relatively movable and fixed to the free end of the other wire 26b. It consists of 29.

As shown in FIGS. 3 and 6, recesses 5a and 5b provided at intermediate heights on both left and right sides of the door 1 are formed by a case 30 embedded in the side portions of the door 1, and are formed by a support roller. 4a and 4b are constituted by a pair of left and right rollers 33 pivotally attached to the tip of a bracket 31 attached to the furniture body 9 by a horizontal support shaft 32 in the left and right direction. Reference numeral 34 denotes a positioning plate spring that acts on the support rollers 4a and 4b, and is installed inside the case 30.

When the door 1 is in the closed state, as shown in FIGS. 3 and 6, the left and right sides of the door 1 are such that the support rollers 4a and 4b that have entered the recessed portion 5a and Sb touch the inner upper surface of the case 30. The door 1 is supported through. At this time, the positioning plate spring 34 engages with the support rollers 4a and 4b, and the door 1
is held in the closed position.

On the other hand, the rotation center members 2a to 3b located at the four corners of the door 1 are connected to the U-shaped recesses 15 of the fixed guide plate 16 and the movable holding member in the corresponding pivoting means 7a and 7b, as shown in FIG. 1
The cylindrical shaft portion 10 is fitted into the recess 22 of 9, and the flat shaft portion 11 is fitted into the free hole recess 17 of the fixed holding member 18. At this time, the movable holding member 19, which is biased by the plate spring 25, has a cylindrical shaft portion 10 that is attached to the U-shaped recess 15.
It is in a horizontal position that prevents it from being pulled out from within. or,
Both wires 262, 26b of the restraining means 8 are in a relaxed contracted state as shown in FIG.

When the left side of the door 1, which is held in the closed position as described above, is pulled toward you in order to open it, for example, about the rotation axis 6b passing through the rotation center members 2b and 3b on the right side,
As shown in FIG. 7, the cylindrical shaft portions 10 of the pivoting center members 2a and 3a held by the left pivoting means 7a, respectively, move the movable holding member 19 of the pivoting means 7a by the urging force of the plate spring 25. The flat shaft portion 11 is pulled out from the U-shaped recess 15 of the fixed guide plate 16 while being pushed open against the force, and the flat shaft portion 11 is pulled out from the free-hole recess 17 of the fixed holding member 18. At this time, the opening movement of the movable holding member 19 pulls the wire 262 in the restraining means 8, and the pull-out prevention member 28 comes into contact with the frame-shaped member 29, eliminating the slack between the wires 26a and 26b and creating a tension state. . Furthermore, when the cylindrical shaft portion 10 is pulled out from the recess 22 of the movable holding member 19, the fixed support shaft 24
The neutral line connecting the movable holding member pivoting vertical shaft 21 is the support shaft 2.
3 crosses over to the opposite side, the direction in which the plate spring 25 urges the movable holding member 19 is reversed, and the movable holding member 19 is opened by the plate spring 25, as shown in the pivoting means 7a on the left side of FIG. direction, the wire 26a
, 26b holds the cylindrical shaft in the illustrated state when it is extracted.

On the other hand, a rotation center member 2b serving as a rotation center of the door 1 to be opened
, 3b are respectively held by the U-shaped recess 15 of the fixed guide plate 16 of the pivoting means 7b and the four parts 22 of the movable holding member 19 in the horizontal position, as shown on the right side of FIG. The flat shaft portion 11 rotates within the free-hole recess 17 of the fixed holding member 18. Therefore, when the door 1 opens to a certain extent, as shown in FIG. It is oriented so that it cannot be pulled out from the opening, and even if you pull the rotation center side of the door 1 toward you, the rotation center member 2. b, 3b
will not come off from the pivoting means 7b.

When the door 1 in the open state is moved to close, when @1 reaches the closed door position, the cylindrical shaft portions 10 of the rotation center members 2a, 3a that have been pulled out from the pivoting means 7a are moved to the cylindrical shaft. Part 1
While moving the movable holding member 19, which is held in the position in which it was pulled out, against the biasing force of the temporary spring 25, the inside of the recess 22 of the movable holding member 19 and the fixed guide plate 16 are moved.
It fits into the U-shaped recess 15 of. Of course, the flat shaft portion 11
fits into the free-hole recess 22 of the fixed holding member 19. On the other hand, as the movable holding member 19 closes by being pushed by the cylindrical shaft portion 10 as described above, the wire 26a that has been pulled is returned to the original state shown in FIG. 4.

Although the case where the door 1 is opened by pulling the left side of the door 1 towards you has been described, it is also possible to open the door by pulling the right side of the door 1 towards you.

In this case, the rotational center members 2b and 3b held by the right pivoting means 7b are pulled out from the pivoting means 7b as described above, and the rotational center member 2a held by the left pivoting means 7a is removed. , 3a as the center.

As is clear from the explanation of the door opening operation, when the opening center member 2a, 3a or 2b, 3b is pulled out from the pivoting means 7a or 7b, the wire 26a in the restraining means 8
, 26b will be nervous. This means that by pulling the door 1 in the closed state toward you, the left and right opening center members 2a to 3b are connected to the pivoting means. Even if I try to pull out both a and 7b at the same time, is it possible to use both left and right pivoting means? Both wires 26a, 26 are held by the movable holding member 19 in a, 7b.
b are pulled at the same time, when the movable holding member 19 is slightly opened, the check means 8Q wires 26a, 26
b becomes tense and prevents the movable holding member 19 from opening any further, so both the left and right opening center members 2a
~3b as pivot means? It is not possible to pull out from a and 7b at the same time.

In addition, when the door 1 is in the open state, the support roller 4a or 4b of the nine furniture bodies fitted in the recessed part 5a or 5b on the side of the rotation center side of the door 1 moves into the recessed part 5 or 5b. The door 1 is supported via the inner upper surface of the case 3o to be formed. During the opening/closing movement of the door, the supporting rollers 4a or 4b come into relative sliding contact with the inner upper surface of the case 3o around the vertical rotation wheel center 6a or 6b, so that the center of the supporting rollers 4a, 4b is The supporting rollers 4a,
When the roller 4b is composed of a plurality of small and medium rollers 33 arranged in parallel, sliding contact with the inner upper surface of the case 30 can be made smoothly. Of course, such support rollers 4a, 4
It is also possible to use a freely rotatable sphere instead of b.

When a wire is used as the restraining means 8 as in the embodiment, the connecting member 27 is omitted and the movable holding members 19 of the left and right pivoting means 7a, 7b are connected to each other with a single wire that is loosened appropriately. You can also do it. Of course, it is also possible to use rondos in place of the wires 26a and 26b in the above embodiment.

In the above embodiment, the pivoting means 7a, 7b and the restraining means 8 are provided on the furniture body 9 side, and the rotation center members 2a to 3b are provided on the door 1 side, but the arrangement can be reversed. Further, the cylindrical shaft portion 10 and the flat shaft portion 1 of the rotation center members 2a to 3b
1 is constructed integrally, however, the rotation center member may be constructed from a cylindrical shaft portion and a flat shaft portion which are each independently attached to an appropriate position.

In addition, when configured as in the embodiment, when the door 1 reaches the closed position, the support rollers 4a or 4b of the nine furniture bodies elastically deform the positioning plate spring 34 of the door, and move the plate. The movable holding part +A' 19, which moves over the protruding part of the spring 34 and closes by being pushed by the cylindrical shaft part 10 of the rotation center member, supports the neutral line connecting the vertical shaft 21 and the fixed support shaft 24. After the shaft 23 crosses inward, the door 1 is pressed to the closed position by being biased in the closing direction by the plate spring 25, and the door 1 can be kept in the closed position without using the 41 Yasochi. There is no need to worry about the valve opening and opening spontaneously.

(Effects of the Invention) By pivoting the door using the door pivoting device of the present invention that can be implemented as described above, the door will come off unexpectedly even if the door is pulled parallel to the front when it is closed. There is no fear and the door can be opened to either the left or right side. Moreover, when opening the door, there is no need for special operations such as separating the rotation center member on the opposite side from the rotation center lip side from the pivoting means, and the opening and closing operation is exactly the same as a conventional single-swing door. You can. Further, since there is no need to provide special operating means on the door etc., it can be implemented at low cost, and a fixed handle of any design can be employed.

In particular, when configured as in the embodiment, there is no way to prevent the door from accidentally coming off when the closed door is pulled parallel to the front, and the door is open or opened. Since the door can be reliably prevented from coming off when the center of rotation of the door is pulled toward the user, it can be used even more safely.
