Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention provides a drawer body to be housed in a cabinet;
The present invention relates to a drawer device with a lid, which includes a lid that covers the open upper surface of the drawer body when the drawer body is stored, and the opening and closing of the lid automatically follows the insertion and removal of the drawer body. 2. Description of the Related Art Conventionally, there have been no cabinets with drawers in general use that have lids that cover the drawers. In addition, in the structure where the drawer is blocked,
The front of the cabinet was equipped with a door or shutter that opened and closed. Problems to be Solved by the Invention In the above-mentioned conventional drawer structure, there was nothing to seal the open top surface of the drawer body when it was stored, so dust, etc. that had entered the cabinet could easily enter the drawer. There are drawbacks. On the other hand, when a box with a lid is used instead of a drawer, the lid has to be opened and closed each time the stored items are taken out, making it cumbersome to put things in and take them out. Therefore, the challenge was to cover the open upper surface of the drawer during storage with a lid to prevent dust from entering, and to make it easy to open and close the drawer. Means for Solving the Problems Therefore, the present invention provides a drawer body that fits into a cabinet so that it can be stored freely, and a drawer that is stacked on the edge of the drawer body so as to be able to come into contact with and separate from the drawer body, so that the open upper surface of the drawer body is sealed when the drawer body is stored. At the same time, one end is placed on the cabinet side,
Lid biasing means that connects the other end to the lid side and biases the lid in two directions, ie, a closing direction and an opening direction, and switching the biasing direction of this biasing device between the closing direction and the opening direction. The present invention provides a drawer device with a lid, comprising a switching means and an interlocking means for interlocking the switching means with the drawer operation and storage operation of the drawer main body, in the cabinet. According to the present invention configured as described above, the open top surface of the drawer body housed in the cabinet is hermetically covered by the lid which is provided with a biasing means and biased in the closing direction. Furthermore, when an attempt is made to take out the drawer body, an interlocking means provided to follow the movement is activated, and the switching means is interlocked to switch the biasing direction of the biasing means, thereby automatically opening the lid. , the drawer itself can be easily pulled out of the cabinet. When storing the drawer further, the interlocking means is activated again near the end of the storage process.
Similarly, via the switching means, the biasing direction of the biasing means is again switched to the direction in which the lid closes, thereby sealing the drawer main body when stored. The present invention solves the above problems as described above. Further, in the present invention, the biasing means is formed by a traction spring having one end connected to a fixed bar fixed in the cabinet and the other end connected to a link extending downward from a side edge of the lid. and the switching means is constituted by a pair of front and rear levers provided between the fixed bar and the link so as to form a four-bar link motion together with the link in the direction of entry and exit of the drawer main body, In the case where the interlocking means is configured by moving the lid and the drawer main body toward and away from each other along the in/out direction, the switching of the biasing direction of the traction spring that pulls between the link and the fixed bar is the direction in which the force is balanced. Since this is done by switching the lid, there are advantages such as less force is required to open and close the lid, less influence on the operation of inserting and removing the drawer body, and easy installation into the cabinet.

In the present invention, the cushioning material provided on the back side of the lid improves the adhesion between the drawer body and the lid, making the seal more secure. In the present invention, the biasing means is constituted by a pressing spring attached to one end of the lid and the other end is brought into contact with the inside of the cabinet 1, and the switching means is constituted by a link provided integrally with the lid. It consists of a pair of front and rear levers that are swingably mounted, and a pivot pin that supports the tip of the lever in an elongated hole on a fixed bar that is fixed inside the cabinet.
When the interlocking means is constructed by direct contact and separation of the lid and the drawer main body along the in/out direction, the structure is simple and there are advantages such as ease of installation into the cabinet. In the present invention, the biasing means for the lid is constituted by a plurality of magnets provided respectively on the cabinet side and the lid side so as to attract or repel each other, Since the lid is brought into contact with and separated from the drawer body by switching the polarity of the magnet, less noise is generated when the lid opens and closes, improving operational reliability and durability. In the present invention, the switching means is formed by a pair of front and rear levers that are swingably provided in the cabinet along the in/out direction of the drawer main body, and a connecting rod that connects the pair of levers; If the interlocking means is constituted by an operating lever whose one end engages with the connecting rod and whose other end approaches and separates at the storage position of the drawer main body, and a restoring spring for the operating lever, the interlocking means is connected to the lid side that opens and closes. This has the advantage of requiring fewer parts to be attached to the lid, making it easier to lift and lower the lid. Examples Examples of the present invention will be explained below with reference to the drawings. Examples shown in Figures 1-3! 1 is provided with a stop Fi2 standing up on the front side, and a rectangular edge 3 is formed to form a housing part 4.

A pair of left and right plate-shaped fixing bars 8, a pair of front and rear levers movably attached to the front and rear of the fixing bar 7, and a pair of levers 9 pivoted to the front and rear pair of levers 8 via connecting pins IO. When installed, the fixed bar 7 is used as a fixed link, and L1 is a link that forms a four-bar link motion along the in/out direction of the drawer body L along with the lever 8, and L1 bends the upper edge of the link 9 inward. The engaging protrusion 12 with the M5, which is shaped by this, engages with the engaging protrusion 1l, so as to link the lifting and lowering (opening and closing) operations of the four-section lever link 8.9 and the lid 5. The guide grooves 13 formed on both sides of the lid 5 are used to disengage the guide groove 12 and the engagement protrusion l1 when the M5 is pulled out forward (to the left in the figure), for cleaning purposes, etc. This is an open end that allows the lid 5 to be attached and detached by itself. Reference numeral 14 denotes a cushioning material which is annularly provided around the back surface of the lid 5 and comes into elastic contact with the edge 3 so as to promote adhesion between the lid 5 and the drawer main body l.

Reference numeral 15 denotes a traction spring stretched between one spring stop 16 projecting inward from the front lower part of the fixed bar 7 and the other spring stop 17 formed at the lower edge of the center of the link 9. This traction spring 15 is connected to the lid 5, which is supported by the lever link 8.9 so that it can be raised and lowered, when the lever 8 is tilted significantly toward the rear, as shown by the solid line in FIG.
The lid 5 is biased in the closing direction, and its traction force maintains the lid 5 in a sealed state. Also, when the lever 8 changes its oblique angle toward the front, the traction spring 15 is released from the boom action of the lever 8, changes the biasing angle, and raises M5 together with the link 9. Switch the traction force in the direction of Reference numeral 18 denotes a stopper formed on the inside of the front end of the fixed bar 7. When the lid 5 is opened, the stopper 18 comes into contact with the front end of the link 9, which moves forward as it rises, to maintain the open state. In addition, 19 in the figure is a tapped hole for attaching the fixing bar 7. In this embodiment (2), as described above, the lid biasing means A for biasing M5 in the closing direction and the opening direction is constituted by the traction spring 15. Further, a switching means B for switching the urging direction of the urging means A includes a fixed bar 7 and a lever 8.
, link 9, and which links the switching means B with the drawing operation and storage operation of the drawer main body 1, the link 9 is integrated with a stopper 2 that shapes the front end surface of the drawer main body 1. It is configured so that it comes into direct contact with and separates from the front end surface 5° of the lid 5 provided for the purpose. This drawer device configured as described above has a drawer main body 1
When it is stored in the cabinet 6, it is sealed by the lid 5 as shown by the solid line in Figure 2, but due to friction when pulling out the drawer body l, the lid 5 and the edge 3 of the drawer body When a force in the pull-out direction is applied to the joint surface of Only the drawer body l that is released can be pulled out. Also, when trying to store the drawer main body 1 in the cabinet 6 from the position where it was, the lid 5, which is moving forward as it rises, touches the front edge 5° of the backing plate 2.
is pushed into the cabinet 6, and in the final stroke of pushing, the angle of inclination of the lever links 8 and 9 changes around 1, and accordingly, the pulling direction of the drawstring spring 15 changes, and the traction spring 15 changes again. Returns to a close, sealed state. In Embodiment I, the inner end of the connecting pin 10 between the lever 8 and the link 9 is extended, and the inner end is used as the engagement protrusion in the above embodiment, and the guide groove 1 is formed accordingly.
In some cases, the full breadth of 2 is admonished. In addition, when the engaging protrusion is directly formed on the lever 8 as described above, the formation of the guide groove 12 on the side surface of the lid 5 is omitted, and fitting portions that engage with the engaging protrusion are formed on the front and rear sides of the side surface. In some cases, the above side surface can also be used as a movable link for a four-bar link motion.
The form of each link member that forms the above-mentioned four-bar link motion is not limited to the illustrated embodiment. Next, in the embodiment (2) not shown in FIG. 4.5, as the biasing means A,
A pressure spring 20 that is compressed between the rear end face of the cabinet 6 and the back front of the cabinet 6 is attached to the rear end surface of the M5, and as a switching means B,
A pair of front and rear levers 8 are swingably attached to a link 9 provided integrally with the lid 5, and each of the levers 8 is attached to the fixed bar 7 by fitting a shaped long hole 8' into the tip thereof. The interlocking means C is equipped with a pivot pin 7°.
As in the case of Embodiment 1, the drawer main body 1 is
This is a case in which the link 9 and the front end surface 5'' of the M5 integrally provided with the link 9 come into direct contact with and separate from each other.
It should be noted that the configuration of each member other than the above is almost the same as in Example I, so the common reference numerals are given to the common members and the explanation thereof will be omitted. In the embodiment (2) configured as described above, when the drawer body 1 is pushed in in the open state shown in FIG. As the lever 8 moves, the elongated hole 8° of the lever 8 descends while being guided by the pivot pin 7°,
As shown in FIG. 5, when the drawer main body 1 reaches the end of its storage stroke, the lid 5, which has descended together with the link 9, covers the top surface of the main body 1 and comes into close contact with the edge 3. In this state, the biasing direction of the pressure spring 20 is switched to the direction of closing the lid 5 as the link 9 and lever 8 move, thereby maintaining the closed state. Then, when the drawer main body l is pulled out to the left in the figure from this sealed state, the leftward movement restraint of the lid 5 is released, and the lever 8 changes to a fully extended state due to the restoring force of the pressing spring 20, and the lever 8. Link 9 returns to the state shown in Figure 4, keeping M5 open. In this embodiment (2), as described above, the opening and closing of M5 automatically follows the insertion and removal of the drawer body l. Next, the embodiment (2) shown in Fig. 6.7 uses a plurality of magnets arranged to attract or repel each other as the lid biasing means 8, and the polarity of the opposing magnets is changed. This is a case where the direction of the biasing force on the lid by the magnetic force is switched. In other words, in Example 2, the link 9 attached to the side of the lid 5
For example, 611 stones N with the lower end faces as N poles are buried in the front and rear of the outer surface of the A lever 8 is attached to the inner surface of the fixed bar 7 so as to be able to freely swing back and forth, and is embedded in the upper end surface of the lever 8 at a distance corresponding to the amplitude of the lever 8. It was. Further, the switching means B of this embodiment (2) is comprised of the lever 8 and
It consists of a connecting rod 21 whose lower ends are connected and extended in the depth direction, and the interlocking means C is connected with its upper end to the rear end of the connecting rod 21 and is attached to the back front of the cabinet 6 so as to be movable in IZ. A bell crank type actuating lever 22;
D is attached to the lower end of the operating lever 22 so as to come into contact with and separate from the rear end surface 23 of the drawer main body l within the cabinet 6.
The operating lever 22 is provided between the IM-obtained trochanter 24, the middle of the connecting rod 21, and the inner surface of the fixed bar 7.
It consists of a restoring spring 25. In addition, in this bear,
In some cases, the attachment of trochanter 24 may be omitted. Further, since the horizontal order of each other member is almost the same as in Example I, (2), common members are given common reference numerals and explanations thereof will be omitted. In Figure 6.7, 26 is an M5 lifting guide consisting of a vertically long hole provided in the fixed bar 7 and a protrusion that fits into the hole. In the embodiment (2), which is protected as described above, in the state shown in FIG. 7, the magnetic force N on the lid side and the magnetic force S on the lever 8 side face each other and attract each other, thereby sealing M5. Then, when the drawer main body l is pulled out to the left in the figure, the operating lever 2 of the interlocking means C
Since the restraint of the second trochanter 24 is released, the upper end of the operating lever 22 is returned to the right in the figure by the action of the restoring spring 25, which had been compressed until then. As the connecting rod 21 moves to the right as the actuating lever 22 returns to its position, the lever 8 rotates counterclockwise in the figure, causing the magnetic force N to oppose the magnetic force N on the lid side. The lid 5 moves up and down through the lifting guide 2 due to the repulsive force of the magnetic forces N and N.
6 and maintain the open state as shown in Figure 6. When storing the drawer main body 1, at the end of the storage stroke, the rear end surface 23 comes into contact with the trochanter 24, which activates the operating lever 22, the connecting rod 2I, and the lever 8, and the magnetic forces N and S are activated. is replaced, and the lid 5 returns to its sealed state. Effects of the Invention According to the present invention configured as described above and operated as described above, the open upper surface of the drawer main body is sealed with a lid when it is stored, so that dust and small insects that enter the cabinet can be prevented. This prevents the intrusion of foreign substances and maintains the cleanliness inside the storage compartment. Furthermore, according to the present invention, the closed lid automatically opens and closes following the movement of the drawer body when it is put in and taken out, so there is no need for the troublesome opening and closing operations as in the box with a lid of -a. In addition, since only a small amount of force is momentarily applied to the operation of the switching means that switches the biasing means that biases the lid in the two directions of opening and closing, it does not greatly affect the ability to put in and take out the drawer itself, and it can be stored with a light touch. effective.
