Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a swingable lid opening/closing device.

The lid body, which is opened and closed by swinging, needs to be held in the closed position by a support frame or the like that swingably supports the lid body. There are various types of lids that can be opened and closed by swinging, ranging from relatively small lids for facsimile machines to relatively large lids such as doors for bookshelves and the like.

These lids are held in the closed position using a click stop method or magnets, and when the lid is in the closed position, it is held in the closed position by a handle provided on the lid. For example, you can use the handle to open it using a lever.

However, depending on the mounting state of the lid, that is, the direction in which the lid swings, it may become difficult to open and close the lid, or the handle may protrude above the plane formed by the lid and its support. As a result, there is a drawback that the plane becomes obstructive and the above-mentioned plane cannot be used effectively.

Referring to FIG. 1, the swinging opening/closing lid will be explained using a facsimile machine equipped with this as an example.A document insertion slot 2 is formed on the top surface of the facsimile machine main body 1. As shown in FIG. A document (not shown) inserted into the insertion slot 2 is sent to the processing section 3 and then ejected onto the paper ejection table 4.

The processing section 3 is provided with a reading device and a transport mechanism (not shown), and its upper part can be opened and closed with an opening/closing lid 5. This opening/closing lid 5 is
It is opened and closed when removing the jam paper or wiping the contact glass in the processing section 3, but if
If a handle is provided on the top surface, opening it as shown by reference numeral 5A would be an ergonomically unreasonable operation if the operator is standing in a normal position. Moreover, the presence of this protruding handle becomes a hindrance to picking up the document discharged onto the paper discharge table 4.

The present invention has been made in view of the above, and includes:
To provide a lid opening/closing device in which a handle is eliminated, the opening/closing lid and a device are located on the same plane, and the lid can be opened and closed with a single touch.

The object of the present invention is to provide a lid that is swingable in a first direction to close and a second direction to open, a means for imparting an opening habit to the lid, and a means for imparting an opening habit to the lid, and a means for imparting an opening habit to the lid. It has a tendency to position the engaging end, and after being pushed by the side surface of the lid that has swung to the closed position, it engages with the engaging portion provided on the lid. The locking lever has a locking lever, a first spring that gives the locking lever the above-mentioned behavior, and a swinging habit in a direction in which the abutting end is positioned in the swinging trajectory of the lid body, and the locking lever has a swinging habit in a direction in which the abutting end is positioned in the swinging trajectory of the lid body, and The charge lever is pushed by the side surface of the swinging lid, and the lid swings in the first direction, pushing both the locking lever and the charge lever out of their swing locus. ,
a second spring that is biased so as to overcome the elasticity of the first spring when the charge lever is pushed during a first operation of engaging the lid body and the locking lever; , a release means for swinging a locking lever engaged with the lid in a direction in which the engagement end thereof retreats from a swinging locus of the lid; a second direction in which the lid body is further swung in the first direction in a state in which the lid body is engaged with the locking lever;
When the above operation is performed, the engagement between the engagement portion of the lid and the engagement end of the engagement lever is released, and the release means is released from the engagement due to the stored elasticity of the second spring. This is achieved by the lid opening/closing device characterized in that the lid swings in the second direction according to its habit by retracting the stop lever from the swinging trajectory of the lid.

According to the present invention, the first action holds the lid in the closed position, and the second action opens the lid, eliminating the need for a handle and allowing easy and effortless opening and closing of the lid. I can do it.

The present invention will be explained below with reference to illustrated embodiments.

In FIG. 2, the lid 10 is pivotally attached to a support 12 by a support shaft 11, and the top surface 10a of the lid and the top surface 12a of the support are located on substantially the same plane. are doing. A spring 13 gives the lid 10 a tendency to open it.

A side surface 10b of the lid body 10 is formed with an engaging portion 14 into which a locking lever, which will be described later, is engaged. A window hole 15 is formed in the side wall 12b of the support body 12 at a position facing the engaging portion 14 of the lid body 10 in the closed position, through which a locking lever and a charge lever, which will be described later, enter and exit. Window hole 15
As shown in FIG. 4, a substrate 16 is fixed with screws 17 near the .

In FIGS. 3 to 5, a support shaft 18 is fixedly planted on the substrate 16. As shown in FIG. Small diameter portion 18 of support shaft 18
A locking lever 19, a release lever 20, and a charge lever 21 are respectively fitted and inserted in order from the proximal end thereof so as to be freely swingable.

The locking lever 19 has one arm 16 of the base plate 16.
The first elastic spring 22, which is stretched between It is given. Further, the hole of the locking lever 19 that fits into the support shaft 18 is formed as a long hole 19b.

The release lever 20 is provided with a release piece 20a that is bent beside the locking lever 19 and brought into contact with one side edge of the locking lever 19. This release piece 20a includes a bent portion 21a of the charge lever 21.
A second compressible spring 23 is stretched between the release lever 20 and the locking lever 19, giving the release lever 20 the tendency to swing in the opposite direction to the locking lever 19. Further, the release lever 20 has an elongated hole 20b that is connected to the support shaft 18.
The lever is pivoted in the region of this elongated hole and can be moved in its longitudinal direction. The lower end 20c of the release lever 20 is brought into contact with the stopper 16b of the base plate 16 by the elasticity of the second spring 23 (see FIG. 5).

As is clear from FIG. 4, the bent portion 21a of the charge lever 21 extends to the vicinity of the large diameter portion 18b of the support shaft 18. The large diameter portion 18b of the support shaft 18 has one end 24a locked to the arm 16a, and the other end 24a.
A spring 24 is wound around the bent portion 21a. Due to the elasticity of the spring 24, the charge lever 24 has a swinging habit that causes its abutting end 21b to protrude from the window hole 15 and to be positioned on the swinging trajectory of the lid 10 (Fig. 4). , 5th
(see figure).

Each of the levers is given a swinging behavior by each spring, and the charge lever 21 is activated by the spring 24 when one end 24b of the spring 24 comes into contact with the stopper 16b of the base plate 16.
(The spring 24 and the stopper 16b are shown separated in FIG. 5.), and the release lever 20 has a swinging behavior in the opposite direction to the charge lever 21 due to the second spring 23. The locking lever 19 is held between the release piece 20a of the lever 20 and the bent portion 21a of the charge lever 21.

The operation of the embodiment configured as described above will be explained based on FIGS. 5 to 8.

As shown in FIG. 5, in a state where the locking lever 19 and the charge lever 21 protrude from the window hole 15, as shown in FIG. When it is swung, the side surface 10b contacts the engaging end 19a and the abutting end 2.
1b, move both levers against its habit,
It is pushed counterclockwise around the support shaft 18 out of the swing locus of the side surface. As a result, the first spring 22, the second spring 23, and the spring 24 are each charged with energy.

In FIG. 6, when the lid body 10, which is in the solid line position, is further swung to the position shown by the chain line, that is, the position where the engaging portion 14 faces the engaging end 19a of the locking lever 19, the locking occurs. Due to its swinging behavior, the lever 19 causes its engaging end 19a to fit into the engaging portion 14, as shown in FIG. After this, excluding the pushing operation on the lid 10, the lid 10 is
Due to its rocking behavior, the lower edge 14 of the engaging portion 14
a is engaged with the engaging end 19a of the locking lever 19 to maintain its closed position.

The locking lever 19 and the charge lever 21 are connected to the lid body 1.
During the first operation in which the locking lever locks the lid after being pushed by 0, when both levers are pushed, the release lever 20 pushes its lower end 20c against the stopper 16b. Although the locking lever 19 is in contact with the lid body 1 (see Fig. 6),
0, the locking lever 19 moves upward in the figure to the elongated hole 19 due to the swinging behavior of the lid 10.
By being raised within the range b, the release lever 20 is also moved within the range of the elongated hole 20b via the release piece 20a, and the lower end 20c and the stopper 16b are moved.
and are separated.

When the lid body 10 is locked as shown in FIG. 7, the second spring 23 of the charge lever 21 (see FIG. 6), which is loaded with energy by being pushed, is attached to the locking lever 19. The elasticity of the release lever 20
is transmitted through. The stored elasticity of the second spring 23 overcomes the elasticity of the first spring 22 of the locking lever 19.
9 in the counterclockwise direction, but the lever 19 has a tendency to swing in the direction of arrow a.
By engaging 0, this is prevented.

Next, to explain the operation when opening the lid, when the lid 10 is swung in the direction opposite to the arrow a in the state shown in FIG. The lower edge 14a of the locking lever 1 is lowered.
Release 9a. The released locking lever 19 is
Due to the stored elasticity of the second spring 23, the release lever 20 is pushed counterclockwise around the support shaft 18. At this time, the locking lever 19 also moves downward due to the elasticity of the first spring 22 through the elongated hole 19b.
It can be moved within the range. The above-described operation of disengaging the lid from the locking lever is referred to as a second operation.

After the second operation, when the pushing force on the lid 10 is cut off, the lid 10 swings in the second opening direction due to its swinging behavior, and the lid opens automatically.

When the lid body 10 swings, the charge lever 21, which had been pushed until now, is moved by the elasticity of the spring 24.
It is returned from the position shown in FIG. 8 to the position shown in FIG. When the charge lever 21 swings,
The locking lever 19 also swings back as shown in FIG. 5 due to the elasticity of the first spring 22 and the spring 24, and at this time the release lever 20 is pushed. Immediately after the second operation, the release lever 20, which had its lower end 20c in contact with the stopper 16b, returns to the second position.
It is pulled downward by the elasticity of the spring 23, and its lower end 20c faces the stopper 16b so as to be engageable (see FIG. 5).

Next, other embodiments of the present invention are shown in FIGS. 9 to 14.
This will be explained based on the diagram.

In FIGS. 9 to 11, the substrate 30 includes
A support shaft 31 is fixedly planted, and a locking lever 32, a release lever 33, and a charge lever 34 are swingably fitted in this order into the small diameter portion 31a of the support shaft 31.

The locking lever 32 has one end 35a of a first spring 35 wound around the large diameter portion 31b of the support shaft 31.
is locked, and the locking end 32a is given a swinging habit in the direction of positioning it on the swinging trajectory of the lid body 10. The other end 35b of the spring 35 is locked to the board 30. The locking lever 32 also has a support shaft 36.
A lever 37 is pivotally mounted by the lever 37, and its free end 37a extends close to the locking end 32a.

The lower end of the release lever 33 is connected to the locking lever 32.
This bent portion 33a
extends below the lever 37, and rests the free end 37a of the lever 37 on its upper edge 33b. In addition, in FIG. 10, the upper edge 3 is shown for convenience of illustration.
3b and free end 37a are shown spaced apart.

On the other hand, a stop lever 39 is pivotally attached to the base plate 30 by a support shaft 38. The other end 40a of a spring 40, whose one end is locked to the base plate 30, is locked to one end 39a of this lever 39, and the other end 40a of a spring 40 locks one end to the base plate 30. giving. A locking step portion 39b and a bent portion 39c are formed at the other end of the lever 39. This bent portion 39c engages with the lever 37 from above, and the lever 37 presses against the upper edge 33b of the release lever 33. Therefore,
The swinging behavior of the stop lever 39 caused by the spring 40 is regulated by the release lever 33 via the lever 37 mentioned above.

The charge lever 34 includes the locking lever 32.
Bent portion 3 extending to the back of the hanging portion 32b of
4a is formed, and a second compressible spring 41 is stretched between this bent portion and the bent portion 33b of the release lever 33. second spring 4
1, the bent portion 33 of the release lever 33
a is in pressure contact with the stepped portion 32c of the locking lever 32, and the bent portion 34a of the charge lever 34 is in pressure contact with the hanging portion 32b of the locking lever 32, respectively. Therefore, the three levers 32, 33, 34 are connected to the first spring 3.
Clockwise due to the elasticity of 5 (in Figure 10)
However, this is prevented by the bending portion 33a of the release lever 33 coming into contact with the stopper 30a formed on the base plate 30. The abutting end 34b of the charge lever 34 is positioned on the rocking trajectory of the lid body due to the behavior of the lever.

The operation of the embodiment configured as described above will be explained in the first section.
This will be explained based on FIG. 0 and FIGS. 12 to 14.

As shown in FIG. 10, with the locking lever 32 and the charge lever 34 protruding from the window hole 15, the lid 10 is swung in the first direction indicated by the arrow, as shown in FIG. and side 10b
pushes both levers 32, 34 against their habits.

When the locking lever 32 and the charge lever 34 are swung, the release lever 33 tries to follow this movement, but the bent portion 33a
This is prevented by engaging with the engagement step portion 39b. Even if the release lever 33 is prevented from swinging, one of the charge levers 34 is pushed and moved by the lid 10, so the second spring 41 connecting both levers is stretched and stored.

Move the lid 10 from the position shown in FIG. 12 to the 13th position.
When the engaging end 32a of the locking lever 32 and the engaging portion 14 are swung to a position shown in the figure facing each other, the engaging end 32a of the locking lever 32 is connected to the engaging portion 14 by the first spring 35 (first spring 35). (See Figures 9 and 10).

When the engaging end 32a of the locking lever 32 enters the engaging part 14, the free end 37a of the lever 37 also enters the engaging part 14. When the pressing force against the lid body 10 is removed, the lower edge 14 of the engaging portion 14
a is pressed against the engaging end 32a and the free end 37a from below by the swinging behavior of the lid. As a result, the lever 37 is swung around its shaft 36, and the stop lever 39, which is in contact with the lever 37 from above at the bent portion 39c, is swung around its shaft 38.

When the stop lever 39 swings, the engaging stepped portion 39b is disengaged from the bent portion 33a of the release lever 33, but at this time, the bent portion 33a has the stepped portion 32c of the locking lever 32. are engaged (see Figure 13).

The release lever 33 is given the habit of swinging counterclockwise about the support shaft 31 by a spring 41 (see FIG. 12) stretched by the pushed charge lever 34, and the above-mentioned engagement is Stop lever 3
2 in this direction, but the engaging end 3
This is prevented by the lid 10 being engaged with 2a.

Further, in the case of the lid body 10 having a habit of opening in the second direction shown by arrow a, the engaging portion 14 is connected to the locking lever 32.
It is held in the closed position by being engaged with the engaging end 32a of.

As described above, in order to separate the lid body and the locking lever that were engaged in the first operation, the lid body 10 is swung in the first direction opposite to the arrow a shown in FIG. 13.
Then, as shown by the chain line in FIG. 14, the restraint of the engaging portion 14 on the engaging end 32a of the locking lever 32 is released, so that the locking lever 32 releases the second spring 41 (the 12th The engagement end 32a is moved counterclockwise by the release lever 33 which receives the elastic force of the lever 33 (see figure), and the engagement end 32a is retracted from the rocking trajectory of the lid body 10.

After this, when the pressing force on the lid 10 is removed, the lid 1
0 swings in the direction of arrow a due to its habit, and the lid opens. Then, when the lid swings and the elements that push the locking lever 32 and the charge lever 34 are removed, both levers close the engaging end 32a and the abutting end 34b, respectively, with the lid again. Swing and position on the swing trajectory of the body. This swinging return of the lever group is achieved by the first spring 35 swinging the locking lever 32, and the stepped portion 32c of this lever 32.
This is done by pushing the bent portion 33a of the release lever 33, and the charge lever 34, which is connected to this lever 33 via the second spring 41, follows this.

In the embodiment of the present invention described above, the spring 1 has a tendency to completely open the lid.
3 (see FIG. 2), the lid does not have to open completely, and the means for imparting the opening habit to the lid is not limited to the spring 13.

Next, Figures 15 to 26 show an example in which the lid is not completely opened, but is simply released from the closed position in the second operation, and the lid is opened manually.
This will be explained based on the diagram. This embodiment is most suitable for use in furniture, bookshelves, etc. Therefore, in the following description, the lid will be referred to as a hinged door.

15 and 17 to 20, FIG. 17 is a partially cutaway plan view, FIG. 18 is a front view, FIG. 19 is a left side view of FIG. 18, and FIG. 20 is a partially cutaway plan view of FIG. It is a left side view. However, in FIGS. 19 and 20, for convenience of illustration, the lever to which the rollers are pivoted is shown swinging.

The substrate 50 is fixed with screws 53, 53 (see FIG. 15) to a support frame 52 that swingably supports a hinged door 51 (see FIG. 16). A shaft 55 is inserted into a bearing portion 54 formed by bending the substrate 50 . A lever 56 is pivotably attached to one end 55a of the shaft 55 to provide an opening behavior to the hinged door.

A roller 57 is rotatably supported on the free end 56a of the lever 56. The lever 56 has a shaft 5
One end 58b of a spring 58, which is wound around the lever 56 and has the other end 58a engaged with the back surface of the base plate 50, is locked, giving the lever 56 a swinging behavior in the direction of pushing the hinged door open. The swinging behavior of the lever 56 is such that the stepped portion 56b is connected to the stopper 54 of the bearing portion 54.
It is regulated by engaging with a.

A support shaft 59 is fixedly planted on the base plate 50, and a charge lever 60, a release lever 61, and a locking lever 62 are each fitted in a swingable manner.

The contact end 60a of the charge lever 60 is connected to the substrate 5.
0 protrudes from the window hole 15 formed in the rising portion 50a. Further, one arm 60c of the same lever 60 is formed with a bent portion 60b.

The free end of the release lever 61 has a spring hook part 61a that is once bent upward and then further bent parallel to the board, and a spring hook part 61a that extends parallel to the spring hook part, then is bent downward and further extends at a right angle. A locking portion 61b is formed.

Between the spring hook part 61a of the release lever 61 and the bent part 60b of the charge lever 60, the charge lever is positioned on the swinging trajectory of the hinged door with its abutting end 60a protruding from the window hole 15. A second spring 63 is applied which provides the directional rocking behavior.

Further, a stopper 50b is formed on the base plate 50, with which the locking portion 61b of the release lever abuts.

The locking lever 62 has an engaging end 62a at one end and a falling portion 62b at the other end. Engagement end 62
One end 64a of a first spring 64 wound around the support shaft 59 is locked to the back surface of the lever 6.
2, the engaging end 62a is given a swinging habit in the direction of protruding from the window hole 15. The other end 64b of the spring 64 is locked to the rising portion 50a of the board 50. Further, a locking step portion 6 is provided at the lower end of the engaging end 62a.
2c is formed. Both the locking lever 62 and the release lever 61 are pivotally connected to a support shaft 59 so as to be movable in the thrust direction, and are normally pressed toward the lever 60 by a helical portion of an extensible spring 64. ing.

As shown in FIG. 17, the locking lever 62 is swung counterclockwise by the elasticity of the first spring 64, and this lever is rotated at the bent portion 61c of the release lever 61. The charge lever 60 connected to the lever 61 by a second spring 63 swings accordingly, causing the engaging end 62a and the abutting end 60a to protrude from the window hole 15. , located on the swinging trajectory of the hinged door.
The swinging of each lever is controlled by the bending portion 61 of the release lever.
c collides with the rising portion 50a of the substrate 50, thereby being blocked.

On the other hand, as shown in FIG. 16, the hinged door 51 has a locking lever 6 facing the window hole 15.
An engagement plate 65 having an engagement portion 14 into which only the second portion enters is fixed.

In the following description, the hinged door 51 and the support frame 52 are not illustrated, and only the engagement plate 65 and the substrate 50 are shown.

Now, as shown in FIG.
and the respective ends 62a, 60a of the charge lever 60 are in a protruding state, and the lever 56 is swinging as shown in FIG. 18 (for convenience of illustration, the free end of the lever 56 is ), as shown in Figure 22,
The engagement plate 65 of the hinged door is brought to the closed position,
When the engagement plate pushes the roller 57 from the position 57A to the position 57B against the elasticity of the spring 58, the locking lever 62 is positioned on the swinging trajectory of the engagement plate. and charge lever 60,
One side 65 of the same plate against each rocking habit.
a in the clockwise direction (see FIG. 21) around the support shaft 59. At this time, the release lever 61 engages its locking portion 61b with the stopper 50b.

The engagement plate 65 is further pushed in the first direction shown by the arrow b in FIG. 22, and the position shown by the chain line in FIG.
In other words, when the engaging portion 14 is pushed to a position where the engaging end 62a of the locking lever 62 faces the locking stepped portion 62c, the engaging end 62a enters the engaging portion 14 (see FIG. 23). ).

Then, when the pushing force against the hinged door is removed, the lower edge 14a of the engaging portion 14 of the engaging plate 65 is moved by the spring 58.
Due to its elasticity, it comes into contact with the lower surface of the engaging end 62a of the locking lever 62, and moves the lever 62 in its axial direction (see FIG. 24). The movement of the locking lever 62 is stopped when the upper end of the engaging portion 62a collides with a stopper 50c formed on a rising portion of the board.

When the locking lever 62 is moved in the axial direction, the release lever 61 that clamps it is also moved in the axial direction, and the engagement between the locking end 61b and the stopper 50b is released (23rd Figure, 2nd
(See Figure 4). As a result, the release lever 61 is activated by the spring 6 which is stored in force by the swinging of the charge lever 60 and overcomes the elasticity of the first spring 64.
3, the bent portion 61c is caused to engage with the side edge 62d of the locking lever 62, and the engaging portion 14 is rotated with respect to the lever 62. It gives them a habit of getting away from it.

However, the locking step portion 62 of the locking lever 62
Since the lever 62 is engaged with the engagement portion 14 of the engagement plate, its swing is restricted, and the lever 62 is moved to the second position.
As shown in Figure 4, the engagement plate 65, or in other words the hinged door, is held in its closed position.

As shown in FIG. 24, in the closed state of the hinged door, when the hinged door, that is, the engagement plate 65 is pushed to the position shown by the chain line, the lower edge 14a of the engagement portion 14 is moved to the locking stage of the locking lever 62. Escape from part 62c. Therefore, the stored elasticity of the second spring 63, which is transmitted to the locking lever 62 via the release lever 61, moves the locking lever 62 toward its locking step 62c as shown in FIG. is swung in a direction to be pulled out from the engaging portion 14. As shown in FIG. 23, this swinging of the locking lever 62 causes the falling portion 62b to come into contact with the side edge 60d of the arm 60c of the charge lever 60 as shown by the reference numeral 62bA, or
It stops at a position where the first and second springs are balanced, but in any case, the engaging end of the locking lever 62 is completely retracted from the rocking trajectory of the engaging plate 65.

The engagement plate 65, which is held in the closed position by the locking lever 62 and released by the release lever 61, is moved by the lever 56, which is biased by the spring 58, through the roller 57, as shown by the arrow in FIG. It is pushed in the second direction shown by a, and the hinged door is opened.

When the hinged door is opened, the element that was pushing the charge lever 60 disappears, so that the energy storage action on the second spring 63 is released. Therefore, the locking lever 62 is swung to the position shown in FIG. 17 by the first spring 64, and the release lever 61 and the charge lever 60 are also swung accordingly. At this time, the locking portion 61b of the release lever 61, which had been located on the stopper 50b, is positioned as shown in FIG. The elasticity of the first spring 64 in the axial direction pushes it toward the charge lever (see FIG. 25→FIG. 26).

As shown in FIGS. 17 and 18, each end of the locking lever 62 and the charge lever 60 protrudes and is positioned on the rocking trajectory of the swing door, and the step 56b of the lever 56 engages with the stopper 54a. Return to the original position and prepare to close the hinged door.

As described above, according to the present invention, when the lid body is simply swung to the closed position, it is held in the closed position, and when the lid body is further pushed, the lid body opens, so that the lid body opens and closes. is done extremely easily.

Further, since no member such as a handle for holding the lid in the closed position or releasing the lid is provided on the lid surface, the surface can be used effectively and safely.

Claims (1)

[Scope of Claims] 1. A lid that is swingably provided in a first direction to close and a second direction to open; means for imparting an opening habit to the lid; and means for imparting an opening habit to the lid; It has a tendency to position its engaging end, and after being pushed by the side surface of the lid that has swung to the closed position, it engages with the engaging portion provided on the lid. a locking lever that provides the locking lever with the above-mentioned behavior; and a locking lever that has a swinging behavior that positions the abutting end in the swinging trajectory of the lid body, and the locking lever has a swinging behavior that positions the abutting end in a direction in which the lid body swings in a closed position. The charge lever is pushed by the side surface of the lid that has been swung, and the lid swings in the first direction, pushing both the locking lever and the charge lever out of their swing locus. a second spring that is biased to overcome the elasticity of the first spring due to the charge lever being pushed during a first operation of moving the lid and engaging the locking lever; and a release means for swinging a locking lever engaged with the lid in a direction in which the engagement end of the locking lever is retracted from the rocking locus of the lid; When the lid is swung in the first direction and the lid is engaged with the locking lever, a second action of further swung the lid in the first direction is performed to lock the lid. When the engagement between the joint portion and the locking end of the locking lever is released, the second
The releasing means retracts the locking lever from the rocking trajectory of the lid due to the elasticity of the spring, thereby preventing the lid from swinging in the second direction due to its habit. Features a lid opening/closing device.
