[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a closing device for closing an opening of an object storage body with an opening / closing body, for example, for closing a storage room under a floor, a safe, a closed room, and the like in a house. Available.

[0002]

2. Description of the Related Art When an object that dislikes moisture or moisture under the floor can be stored in an underfloor storage of a house, the underfloor storage is composed of a main body that is an object storage body and a lid that is an opening and closing body. The opening of the main body can be freely opened and closed by the lid, an elastic sealing member is provided on the main body or the lid, a hook member is provided on one of the main body and the lid, and an engaging member capable of engaging the hook member is provided on the other. When the opening of the main body is closed with the lid, the lid can be fixed to the main body by compressing the seal member with a large load to block the inside and outside of the main body and engaging the hook member with the engaging member. It is conceivable to do so.

[0003]

As described above, the seal member which is compressed by a large load is provided in the underfloor storage, and the opening of the main body is sealed by the compression of the seal member so that the inside and outside of the main body can be reliably shut off. In order to do so, a large closing force must be applied to the lid by pushing the lid by hand or the like until the hook member is engaged with the engaging member, and according to this, the lid is closed. A large work force is required for a person, which is not preferable.

An object of the present invention is to provide an opening / closing body such as a lid for sealing an opening of an object storage body in which an object is stored, such as an underfloor storage in which moisture or moisture under the floor is stored. When compressed and closed, the seal member can be compressed with a small operating force,
It is an object of the present invention to provide a device for closing an object storage body, which can securely close and close the object storage body by an opening / closing body using a seal member.

[0005]

SUMMARY OF THE INVENTION According to the present invention, there is provided an apparatus for closing an object storage body, comprising: an object storage body having an opening through which an object can enter and exit; A closing force input member to which a closing force is input to one of an opening and closing body that seals the opening by compressing a seal member between the closing force input member and a closing force transmission mechanism. An output member connected thereto, and an engaging member which engages the output member to close the opening / closing body with respect to the object container is provided on the other side, and the closing force transmission mechanism is closed. It is a booster mechanism for increasing the closing force from the force input member and transmitting the force to the output member.

According to the present invention, the output member provided on one of the article storage body and the opening / closing body is engaged with the engagement member provided on the other, so that the opening / closing body compresses the sealing member and the object is compressed. The opening of the storage body is closed, and the output member is engaged with the engagement member by transmitting the closing force from the closing force input member to the output member via the closing force transmission mechanism, Since the closing force transmission mechanism increases the closing force from the closing force input member and transmits it to the output member, the closing force transmission mechanism compresses the seal member and closes the opening of the container body with the opening / closing body. The operation force input to the member may be small, and the closing operation of the object storage body can be easily performed.

In the present invention, the closing force input member may be a member which is operated by inserting a key, that is, a locking cylinder which has a keyhole into which the key is inserted and which is rotated by the key. Is not
A push button or lever that is pushed or rotated by hand or the like may be used.

When the closing input member is a locking cylinder that is rotated by a key, if it is necessary to provide a locking device in the object storage body whose opening is opened and closed by the opening and closing body, the locking device and the opening and closing body are used. When the opening of the object storage body is closed, a mechanism necessary for compressing the seal member can be shared, and the closing device according to the present invention also serves as a locking device. And the number of parts can be reduced. In addition, since it is not necessary to provide a push button or a lever that protrudes to the outside in the object storage body or the opening / closing body, the appearance can be simplified, and inconvenience such as erroneous contact with these can be eliminated.

The closing force transmitting mechanism, which is a booster mechanism, may be, for example, a link mechanism, a lever mechanism, or a gear train mechanism, and its structure and type are arbitrary.

Further, the closing force transmitting mechanism may be such that the closing force transmitted to the output member by being increased by this mechanism is enlarged to the size from the beginning and transmitted to the output member. A mechanism in which the closing force from the member gradually increases and is transmitted to the output member, in other words, a mechanism in which the closing force transmission mechanism is a progressive mechanism may be used.

If the closing force transmitting mechanism is a progressive mechanism, the seal member is compressed when the opening of the object storage body is closed by the opening / closing body, and the load required for this compression increases the amount of compression. Even with the increase, the closing force transmitted from the closing force input member to the output member gradually increases, so that the sealing member can be compressed while applying the same or substantially uniform operating force to the closing force input member. This operation can be facilitated.

Further, the number of output members may be one for one closing force input member, but the number may be plural, and a closing force transmitting mechanism for connecting these closing input members and output members. May be the same as the number of output members.

When the number of output members is one for a single closing force input member and the number of closing force transmission mechanisms is the same as the number of output members, the number of engaging members with which the output member engages is also plural. Therefore, the closing of the opening / closing body to the object storage body performed by the engagement of the output member with the engagement member is performed at a plurality of locations, and therefore, the compression of the seal member is performed by the closing force from the plurality of locations. It is possible to compress the sealing member in an equal or almost equal state.

As described above, when the number of output members is plural,
When the number of the closing force transmission mechanisms is the same as the number of output members, each of the closing force transmission mechanisms, which are boosting mechanisms, may be configured with the same principle mechanism or may be configured with different principle mechanisms.

When a plurality of closing force transmission mechanisms are configured as having the same principle mechanism, all or many members of the mutual closing force transmission mechanisms can be used in common. Can be facilitated.

When the number of output members for one closing force input member is two, these output members are arranged on opposite sides to the closing force input member, and the closing force input member and the output member are arranged. It is preferable that the two closing force transmitting mechanisms connecting the two members are mechanisms extending from the closing force input member to opposite sides.

With this configuration, for example, the closing force input member, the closing force transmitting mechanism, and the output member are provided in the opening / closing member of the object storage body and the opening / closing member, and the opening / closing member that can be secured for disposing these members. Even if the space is elongated, the closing force input member, the closing force transmitting mechanism, and the output member can be effectively disposed in the elongated space.

Here, setting the number of output members to two or more for one closing force input member may be the case where the number of closing force input members is one. May be done.

In the above, the relationship between the object storage body and the opening / closing body that opens and closes the opening of the object storage body may be such that the opening / closing body may be rotatably attached to the object storage body with a hinge, or The opening / closing body may be slidably attached to the object storage body, and furthermore, the opening / closing body may be detachably mounted on the object storage body, and the relationship is arbitrary.

The shape of the container may be any shape such as a box, a cylinder, a cone, and a sphere, and the shape of the opening of the container may be any shape such as a square or a circle. The body can have any shape according to the shape of the opening.

Further, the opening may be formed on the upper surface of the object storage body or on another surface such as a side surface, and the formation position is arbitrary. The opening / closing body that opens and closes the opening may cover the surface of the object container in which the opening is formed and another surface connected to this surface, or the opening may be It may be configured to cover only the surface of the formed article storage body. In the case of the former, the closing force input member including the locking cylinder may be disposed on a surface of the opening / closing body that covers the surface on which the opening of the article storage body is formed, and the opening of the article storage body is formed. May be arranged on the surface of the opening / closing body that covers the surface connected to the provided surface.

An example of an object storage body to which the closing device according to the present invention can be applied is a storage room under the floor of a house. In addition to this, the closing device according to the present invention includes a storage container placed in the soil or underwater, an airtight container, It can be applied to safes that require sex, and
The present invention can also be applied as a closing device for sealing a closed room that is required to be able to be isolated from an adjacent space.

Is compressed between the main body 4 and the lid 6, whereby the opening 5 is sealed and the inside and the outside of the main body 4 are shut off with airtightness and watertightness. Even if the object to be taken in and out is a food or the like that dislikes moisture or moisture existing under the floor of the house, the food or the like can be stored in the main body 4 in a state of being isolated from moisture and moisture.

At the center of the front part 6B of the lid 6 in the left-right direction,
The tip of a locking cylinder 8, which is a locking device for locking the lid 6 to the main body 4, protrudes. The internal structure of the front part 6B around the locking cylinder 8 is shown in FIG. 3, and FIG.
FIG. 4 is a sectional view taken along line IV.

As shown in FIG. 4, a channel member 9 with a lip 9A is attached to the rear surface of the front portion 6B of the lid 6, and extends forward from the upper and lower ends of the web 9B of the channel member 9 in the horizontal direction. A locking cylinder 8 and a closing force transmission mechanism using the locking cylinder 8 as a closing force input member are housed and disposed between the upper flange 9C and the lower flange 9D.
It protrudes from B. In FIG. 3, a first closing force transmitting mechanism 10 and a second closing transmitting mechanism 11 having the locking cylinder 8 as a common closing force input member are extended and arranged in the left-right direction of the locking cylinder 8. Closing force transmission mechanism 1
A hook member 12 which is a closing force output member is provided at the end of 0 and 11 so as to be rotatable about a pin 13.

The first closing force transmitting mechanism 10 will be described. A keyhole 8A is formed, and the locking cylinder 8 is connected to the locking cylinder 8 at the rear end of the locking cylinder 8 which is turned to the right by operating a key inserted into the keyhole 8A. A cylinder base member 14 is provided, which rotates integrally with the locking cylinder 8. The first arm 14A and the second arm 14B extending up and down of the cylinder base member 14 include the first arm 14A and the first arm 14A shown in FIG. The first to fourth link members 15 to 8 of the first closing force transmission mechanism 10 are arranged between the right and left hook members 12.

The first link member 15 is connected to the first arm portion 14A by a pin 19, and the first link member 15 is formed with a vertically long slot through which the pin 19 penetrates (not shown). . The first link member 15 is guided by a guide member 20 attached to the web 9B of the channel member 9 and an upper flange 9C of the channel member 9 and is slidable in the left-right direction. The left end of the second link member 16 is connected by a pin 21, and the first link member 15 is formed with a vertically long slot 22 through which the pin 21 passes.

The second link member 16 is attached to the web 9B of the channel member 9 so as to be rotatable about a pin 23 at the lower end, and a right end of the second link member 16 has a rod-shaped third member.
The left end of the link member 17 is connected by a pin 24.
The right end of the third link member 17 has a fourth link member 1
8 are connected by a pin 25, and the fourth link member 18 is connected to the first
As with the link member 15, the web 9B of the channel material 9
Is guided by the guide member 26 attached to the base member 9 and the lower flange 9D of the channel member 9, and is slidable in the left-right direction. The right output member 12 in FIG. 3 is connected to the fourth link member 18 by a pin 27, and the fourth link member 18 is formed with a vertically long hole 28 through which the pin 27 passes.

For this reason, when the locking cylinder 8 is rotated to the right by a predetermined angle with the key inserted into the keyhole 8A, as shown in FIG. 5, the first of the cylinder base members 14 which rotates by the same angle in the same direction. The first link member 15 slides to the right by the arm portion 14A, whereby the second link member 16
Rotates right around the pin 23. Then, the fourth link member 18 slides rightward via the third link member 17, and the output member 12 rotates leftward about the pin 13.

The second closing force transmission mechanism 11 shown in FIG.
Is constituted by a locking cylinder 8, a cylinder base member 14, and first to fourth link members 29 to 32 arranged between the second arm 14B of the cylinder base member 14 and the left output member 12. (2) The closing force transmitting mechanism 11 has the same principle as the first closing force transmitting mechanism 10. When the locking cylinder 8 is rotated to the right by a key, the closing force transmitting mechanism 11 operates symmetrically with the first closing force transmitting mechanism 10. The second arm 14B extending downward.
Except for the first link member 29 connected to the locking cylinder 8, the second to fourth link members 30 to 32 are connected to the locking cylinder 8 by the second to fourth link members 16 to 1 of the first closing force transmission mechanism 10.
8 and a symmetrical configuration, a symmetrical arrangement,
The hook member 12 on the left side of FIG. 3 also has a symmetrical shape and a symmetrical arrangement with the hook member 12 on the right side.

When the opening 5 of the main body 4 is closed by the lid 6, the left and right output members 1
An engaging member 33 is fixed at a position adjacent to the second member 2, and as shown in FIG.
A protruding portion 33A that protrudes from the main body 4 at right angles and horizontally is provided.

For this reason, after closing the opening 5 of the main body 4 with the lid 6, the locking cylinder 8 is turned to the right with a key, and the first and second closing force transmission mechanisms 10 and 11 are operated as described above.
When the left and right hook members 12 are rotated about the pins 13, these hook members 12 are engaged with the protrusions 33 </ b> A of the engagement member 33, whereby the lid 6 opens on the upper surface of the main body 4. The opening 5 is closed while compressing the sealing member 7 arranged around the portion 5.

Of course, when the locking cylinder 8 is rotated to the left by the key, the first and second closing force transmitting mechanisms 1
The hook member 12 is separated from the projection 33A of the engagement member 33 by the operation reverse to that described above at 0 and 11, and the lid 6 can be opened.

FIG. 6 is a dynamic diagram of the first closing force transmission mechanism 10 when the locking cylinder 8 is rotated to the right by the key. Since the second closing force transmitting mechanism 11 is the same principle mechanism that is symmetrical to the first closing force transmitting mechanism 10, the second closing force transmitting mechanism is obtained by converting the dynamic diagram of FIG. 6 into a symmetrical diagram. It becomes 11 dynamics diagrams.

In FIG. 6, A is the pin 21, B is the pin 24, C is the pin 23, D is the pin 25, and E is the pin 2
7, F indicates the pin 13, and G indicates the contact point between the hook member 12 and the projection 33A of the engaging member 33.
L1 is the distance between FEs, L2 is the distance between FGs,
L3 indicates the distance between ACs, L4 indicates the distance between BCs, α indicates the angle formed by the line segment EF with the vertical direction, β indicates the angle formed by the line segment AC with the vertical direction, and γ indicates the angle formed by the line segment BC. The angles formed with the vertical direction are shown.

Fg is the load applied to G (the load at which the hook member 12 engages with the projection 33A of the engagement member 33). This Fg is generated by the horizontal load Fe acting on E. The following equation is established by the rotational moment about F.

Fe · L1 · cosα = Fg · L2 Therefore, Fe = (Fg · L2) / (L1 · cosα) (1) Further, Fe is a load acting on D in the horizontal direction. Fe is also the horizontal load on B. Since Fe in B is generated by Fa, which is a horizontal load that causes A to rotate about C and the center, the following equation is established by the rotational moment about C.

Fa · L3 · cosβ = Fe · L4 · cosγ Therefore, Fa = (Fe · L4 · cosγ) / (L3 · cosβ) (2) From the equations (1) and (2), Fa = (Fg · L2 · L4 · cosγ) / (L1 · L3 · c
osα · cosβ) In this equation, as the locking cylinder 8 is rotated by the key, α and β gradually decrease, and γ gradually increases. Therefore, when Fa is constant,
Fg gradually increases.

That is, the closing force transmission mechanism 10 is a booster mechanism that expands Fa to Fg and transmits it to the hook member 12. For this reason, even if the locking cylinder 8 is rotated with a small operation force of the key, the load at which the hook member 12 engages with the projection 33A of the engagement member 33 increases, and the lid 6 causes the seal member 7 to rotate. The opening 5 of the main body 4 is closed by being surely compressed with a large load.

In particular, Fa is generated when the locking seal member 8 is rotated by a key, and even if the locking cylinder 8 is always rotated with a constant operating force, the cylinder base member shown in FIGS. 14 and a first arm portion 14A extending upward.
The pin 19 connecting the link member 15 rotates about the locking cylinder 8 while the horizontal movement component same as the working direction of Fa gradually decreases as the right rotation of the locking cylinder 8 proceeds. Therefore, Fa itself gradually increases with the progress of the right rotation of the locking cylinder 8, so that Fg is further enlarged, and the opening 5 of the main body 4 obtained by the lid 6 for compressing the sealing member 7 is formed. Hermeticity can be improved.

Also, Fa = (Fg · L2 · L4 · cos
γ) / (L1 · L3 · cosα · cosβ)
Becomes near zero, Fg becomes extremely large, and
At this time, since the locking cylinder 8 is rotated rightward to increase the Fa, the closing force transmission mechanism 10 gradually increases the closing force from the locking cylinder 8 as the closing input member to the hook member 12 as the output member. It is a progressive mechanism for transmitting.

For this reason, even if the thickness of the seal member 7 (the vertical dimension of the seal member 7 in FIG. 3) is increased, so that the compression allowance of the seal member 7 is increased, Even if the compression proceeds and the amount of compression increases and the repulsive force from the seal member 7 increases, the seal member 7 can be reliably compressed, and as a result, the opening 5 Can be made extremely large.

In addition to the above, according to the present embodiment, the hook member 12 is engaged with the projection 33A of the
A closing force for closing the cover 6 is input from a locking cylinder 8 that is rotated by rotating a key by inserting a key into the keyhole 8A, so that a mechanism for closing the cover 6 while compressing the seal member 7 and a cover 6 Of the underfloor storage 1 which is locked to the main body 4 by a key.
Even with a locking device, the structure can be simplified and the number of parts can be reduced accordingly.

Since there are two output members 12 for one locking cylinder 8 and the same number of closing force transmitting mechanisms as the output members 12 and two engagement members 33, the output member 1
There are two places where the lid 6 is closed by engaging the projection 2 with the projection 33A of the engagement member 33. For this reason, the portion of the seal member 7 which is finally compressed by the lid 6 can be evenly compressed, and it is possible to prevent the sealing of the opening 5 of the main body 4 from being uneven due to the compression of the seal member 7.

Since the first and second closing force transmitting mechanisms 10 and 11 having the same number as the output members 12 are boosting mechanisms based on the same symmetrical principle mechanism, the first closing force transmitting mechanism 10 And the constituent members of the second closing force transmission mechanism 12,
Second link members 16 and 30 and third link member 17 of each other
And 31 and the fourth link members 18 and 32 can be used as common parts having the same shape by turning one of them upside down with respect to the other, which is effective in manufacturing parts.

Further, according to the present embodiment, the two output members 12 are arranged in the left and right directions opposite to each other with respect to the locking cylinder 8, and the first closing force transmitting mechanism 10 and the second closing force transmitting mechanism 11 are also provided. Since they extend from the locking cylinder 8 in the left-right direction, these closing force transmission mechanisms 10, 1
The front part 6 which can be secured on the lid 6 for storing and placing the front part 1
Even if the space of B is slender, it can be effectively arranged in this space.
