Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bidirectional drawer which can be pulled out to any side in the sliding direction and can be used from any side, and is particularly suitable for an incubator for newborns and the like. The present invention relates to a bidirectional drawer.

[0002]

2. Description of the Related Art It is important to place a newborn in an environment where the temperature and humidity are optimal. In particular, low-birth-weight babies and high-risk babies are required to maintain a more accurate environment. Therefore, a closed incubator that can control the temperature, humidity, oxygen concentration, and the like, which are environmental elements in the incubator, with high accuracy is used. However, this closed incubator encloses the child with a hood so that the environmental elements can be easily controlled. The presence of this hood impedes rapid treatment of the child. In addition, this type of incubator also has the disadvantage that it takes time to warm up until the environment is ready. Therefore, in order to enable quick treatment and shorten the time required for warm-up, an open type incubator that directly heats a patient by radiant heat without using a hood and maintains a desired body temperature is also provided. Further, a portable incubator or the like for transporting a patient to another medical facility is also provided, and can be selected according to the purpose of use.

[0003] Since the open-type incubator has a structure in which a child is laid on a bed whose periphery is open and observed, the child can be observed, examined, and treated from any direction around the incubator. On the other hand, the incubator is provided with a drawer for storing diagnostic tools, treatment tools, etc., and since the treatment can be performed from any direction, this drawer can be pulled out in any of the sliding directions. Have been.

The drawer can be used by being pulled out from any direction. For example, when the drawer is pushed in from one side and the drawer is to be housed in its housing, the drawer has a large pushing force. Must not protrude toward the For this reason, it is necessary to prevent the drawer from sliding while the drawer is housed in the housing. In order to prevent the drawer from sliding, for example, a locking mechanism is provided between the drawer and the housing, and when the drawer is housed in the housing, the locking mechanism operates to prevent the drawer from sliding. It is to be done.

[0005]

By the way, it is forbidden to apply noise or impact to a child laid on an incubator bed. Infants cannot complain of noise or shock, accumulating stress, which is not desirable for treating children. However, in the conventional two-way pull-in / draw-out drawer used in the incubator described above, noise and impact are generated when the drawer and the casing are disengaged by the locking mechanism. This is because the structure of the locking mechanism includes, for example, a locking claw and a locking portion that engages with and disengages from the locking claw. Or an impact is caused. If these locking mechanisms do not exist, the drawer pushed in from one side will protrude to the other side, and it will be inconvenient because it will obstruct the operator who is performing work such as treatment on the other side.

Further, depending on the structure, there is a structure in which the locking mechanism must be released when the drawer is pulled out. For example, the drawer is provided with a release function in a gripping portion that is gripped when the drawer is pulled out. The release function is activated by pulling the gripper to release the locking mechanism, and the drawer can be pulled out as it is. In the case of this structure, when the drawer is pushed out to the other side in order to be used by the operator on the opposite side, the drawer is pushed in while pulling the grip portion, and the operability is deteriorated. In particular, when trying to push out the drawer in a situation where both hands can not be released during treatment etc., it is convenient if it can be pushed out with a knee etc., but it can not be released because the locking mechanism can not be released, and A separate assistant is required.

Furthermore, in order to smoothly engage and disengage the locking mechanism, it is desirable that the locking mechanism has an appropriate play. This drawback causes the drawer to slightly move in the housing. In some cases, the drawer slightly protrudes from the housing, which detracts from aesthetic appearance.

Accordingly, an object of the present invention is to eliminate the need to release the locking mechanism when pulling out or pushing out a drawer, and to prevent noise and impact when the drawer is housed in a housing to prevent sliding. It is an object of the present invention to provide a two-way pull-in / draw-out type drawer which is prevented from being generated as much as possible.

[0009]

As a technical means for achieving the above object, a two-way drawer / drawer according to the present invention is housed in a cylindrical housing and is slidable with respect to the housing. In this case, in the two-way pull-in / draw-out type drawer which can be inserted / removed from the opening on either side of the housing by this sliding, a fixing provided in connection with the inner wall surface of the housing along the sliding direction of the drawer.

[0010] As a configuration in which the sliding restricting means and the sliding driving means and the sliding body are each attracted, one of the sliding body and the sliding restricting means and the sliding driving means is a permanent magnet. The other is composed of a magnetic material, or both are composed of permanent magnets, and a magnetic force acts between the sliding body and the sliding body regulating means or the sliding driving means,
The sliding body is magnetically attached to the sliding body regulating means and the sliding driving means.

[0011] When the drawer is pulled out of the housing by gripping the grip portion or the like from the closed state of the drawer, the drawer is pulled out. At this time, the sliding body magnetically attached to the sliding restricting means and the sliding driving means on the back side of the drawer pulled out,
The drawer is pushed by the sliding drive means accompanying the sliding of the drawer, is separated from the slide restricting means, and moves along the fixed side guide means. Further, the sliding body magnetically attached to the slide regulating means and the slide driving means on the front side of the drawer is maintained in a state magnetized to the slide regulating means, and the sliding body is moved with respect to the sliding body. The guide means will slide.

When the open drawer is pushed in to close it, the moving side guide means slides on the sliding body magnetically attached to the front side slide regulating means and the back side slide drive means. The sliding member on the back side magnetically attached to the sliding driving means slides with respect to the fixed-side guiding means with the movement of. When the drawer slides with respect to the housing and slides to a position at which the drawer is closed, the rear sliding body is magnetically attached to the sliding restricting means, and the front sliding driving means is the sliding body. And magnetically attached. For this reason, the drawer stops at a fixed position with respect to the housing. That is, the drawer is in a closed state. The same applies to the case where the drawer is inserted and removed from the other side.

When the drawer is inserted or removed, the drawer must be pulled out against the magnetic force acting between the sliding body and the sliding body restricting means and the sliding driving means. It can be easily opened without the need, and the generation of noise and impact when the locking means is engaged or released can be prevented as much as possible.

According to a second aspect of the present invention, there is provided a bidirectional pull-in / draw-out type drawer, wherein the slide restricting means supports the fixed-side guide means, and the slide drive means supports the movable-side guide means. Features.

When the fixed-side guide means and the movable-side guide means are constituted by rods or the like, a support member for supporting these on the side surface of the housing or the wall surface of the drawer is required. If this supporting member is used also as the manual restricting means and the sliding driving means, the number of parts is reduced, the structure becomes simpler and the weight can be reduced, and the manufacturing cost can be reduced.

Further, the two-way drawer / drawer according to the third aspect of the present invention is housed in a cylindrical housing and is slidable with respect to the housing. This sliding allows the opening on either side of the housing. In a bidirectional insertion / removal type drawer that can be inserted and removed from a drawer, a pair of sliding bodies that slide along with the slide of the drawer are provided, and when the drawer is pulled out and slid, the drawer of the pair The first sliding body on the front side of the forward movement maintains the storage position, and the second sliding body on the rear side of the forward movement moves forward, and when the drawn drawer is pushed in and stored, the second sliding body is moved to the storage position. When the pair of sliding bodies are retracted and the pair of sliding bodies are in the housing position, the sliding bodies maintain the housing position by magnetic force.

In the state where the drawer is housed in the housing, the sliding body is maintained in the housing position by receiving the magnetic force, so that the drawer is prevented from being carelessly projected from the housing. Also,
When pulling out the drawer, the drawer may be pulled out with a force against the magnetic force, so that the drawer can be pulled out with a slight force.

FIGS. 1 to 4 are views showing an assembly of a slide guide mechanism 10 for guiding the slide of the drawer 7. FIG. The sliding guide mechanism 10 is configured by combining a fixed-side base plate 11 and a moving-side base plate 12 whose longitudinal direction is the sliding direction of the drawer 7. As shown in FIG. 4, the fixed side base plate
At both ends in the longitudinal direction of 11, a fixed-side support plate portion 11a as a slide restricting means is formed by bending the end portion, and is appropriately deviated from the center portion of the fixed-side support plate portion 11a. At the position, a supporting portion 11b is formed so as to protrude. On the other hand, at both ends in the longitudinal direction of the moving base plate 12, moving side support plate portions 12a as sliding drive means are formed by bending the ends. Then, as shown in FIG.
11a and the moving-side support plate 12a are located at positions where they do not overlap.

The support portions 11 at both ends of the fixed-side base plate 11
A fixed rod 13 as fixed-side guide means is bridged and supported by b. On the other hand, a moving rod 14 as moving-side guide means is supported by being bridged between the moving-side support plates 12a at both ends of the moving-side base plate 12. As shown in FIGS. 1 and 2, a slider block 15 as a pair of sliding bodies is loosely fitted to the fixed rod 13 and the moving rod 14.

A pair of permanent magnets is provided on the surface of each of the pair of slider blocks 15 facing the fixed side support plate 11a.
16a are buried at appropriate intervals, and a pair of permanent magnets 16b are buried at appropriate intervals on the surface facing the moving-side support plate 12a. Further, the fixed-side support plate portion 11a and the movable-side support plate portion 12a are formed of a magnetic material. In the present embodiment, the fixed-side base plate 11 and the movable-side base plate 12 are bent to form these support plates. Since the parts 11a and 12a are formed, the fixed base plate 11 and the movable base plate 12
Are each formed of a magnetic material, but the fixed-side base plate 11 and the moving-side base plate 12 are formed of a non-magnetic material, and the fixed-side supporting member 11a and the moving-side supporting member 12a are The structure attached to 12 may be sufficient. That is, the slider block 15 is
Or in the state located at the end of the moving rod 14,
Magnetically attached to one or both of the fixed-side support plate 11a and the movable-side support plate 12a.

As shown in FIG. 5, the fixed-side base plate 11 is screwed into a screw hole 21 formed in the fixed-side base plate 11 on the inner wall surface of the housing 20 accommodating the drawer 7 (see FIG. 1). Is fixed with a set screw that penetrates through. On the other hand, the movable base plate 12 is fixed to the outer wall surface of the drawer 7 with a set screw or the like penetrating a screw hole 22 (see FIG. 1) formed in the movable base plate 12. As a result, the drawer 7 is connected to the housing 20 and the drawer 7 is
Can be slid against. Further, the casing 20 is formed in a cylindrical shape and is open on any side in the sliding direction of the drawer 7, so that the drawer 7 can be inserted and removed from any side of the casing 20. It should be noted that handles are provided on the front and back of the drawer 7 for putting hands and fingers when inserting and removing the drawer 7.

The operation of the embodiment of the bidirectional drawer / drawer according to the present invention constituted as described above will be described below.

When the drawer 7 is housed in the housing 20 and closed, as shown in FIG.
14 and the slider block
Numerals 15 are located at the ends of the fixed rod 13 and the movable rod 14, respectively, and are magnetically attached to the fixed-side support plate 11a and the movable-side support plate 12a facing the outer surfaces of the slider block 15.

In this state, when the drawer 7 is pulled out while holding the handle 7a, the movable base plate 12 is also pulled out while the drawer 7 is pulled out, and the movable base plate 12 is moved to the fixed base plate 11. Will move.

Now, it is assumed that the moving base plate 12 moves in the direction of arrow P in FIG. Since the fixed base plate 11 is attached to the housing 20, the fixed base plate 11
And the fixed rod 13 supported by the same is fixed at the position shown in FIG. When the moving base plate 12 moves in the direction of the arrow P, the moving rod 14 also moves in the same direction. Moving rod
Since the slider block 15 is magnetically attached to the moving-side support plate portion 12a supporting the end of the arrow-marked Q side in FIG. 1 by a permanent magnet 16b in the arrow P direction of the moving-side support plate portion 12a in FIG. As a result, the slider block 15 is pushed by the moving-side support plate portion 12a, is separated from the fixed-side support plate portion 11a, and slides in the arrow P direction along the fixed rod 13.

On the other hand, the arrow P in FIG.
The slider block 15 on the arrow P side is also magnetically attached to the movable side support plate portion 12a supporting the end on the side of the arrow P by the permanent magnet 16b, and the movable side support plate portion 12a on the arrow P side is shown in FIG. When moving in the upward arrow P direction, the slider block 15 does not move because it is restricted by the fixed-side support plate 11a, and the movable-side support plate 12a is separated from the slider block 15 in the arrow P direction. Will move. At this time, the moving rod 14 moves in the same direction while sliding with respect to the slider block 15. That is, as shown in FIGS. 2 and 6, the drawer 7 is pulled out of the housing 20. Then, when the drawer 7 is pulled out to an appropriate position, the contents are taken in and out, and the drawer 7 is pushed in. When the drawer 7 is pulled out most, the slider block on the arrowhead Q side
15 comes into contact with the slider block 15 on the arrow P side.

When the drawer 7 is pushed in, the movable base plate 12 moves from the position shown in FIG. With the movement of the movable base plate 12, the movable rod 14 also moves in the same direction, and the movable support plate on the arrowhead Q side.
The slide block 15 on the arrowhead Q side magnetically attached to 12a via the permanent magnet 16b also moves in the same direction along the fixed rod 13. When the moving-side base plate 12 moves to a position substantially overlapping with the fixed-side base plate 11, the slide block 15 on the arrowhead Q side comes into contact with the fixed-side support plate portion 11a of the fixed-side base plate 11, and the permanent magnet 16a As a result, the slide block 15 is magnetically attached to the fixed-side support plate 11a. On the other hand, the moving base plate
When the movable side support plate portion 12a on the arrow P side comes into contact with the slide block 15 on the arrow P side by the movement of the arrow 12, the permanent magnet 16b
As a result, the moving-side support plate portion 12a and the slider block 15 are magnetically bonded. That is, the movable-side base plate 12 overlaps the fixed-side base plate 11, and a pair of slide blocks
15 are fixed support plate 11a and movable support plate 12
The drawer 7 is closed and housed in the housing 20 in a state where the drawer 7 is magnetized by the permanent magnet 16. Moreover, the slide block by the permanent magnet 16 when the drawer 7 is closed
By the magnetic adhesion between the support 15 and the support plate portions 11a and 12a, a click feeling that the drawer 7 is closed can be obtained. In addition, since the drawer 7 is magnetically attached by the permanent magnet 16, the drawer 7 does not inadvertently protrude from the housing 20.

When the movable base plate 12 moves in the direction of arrow Q in FIG. 1 when the drawer 7 is pulled out from the housing 20, the slider block 15 on the arrow Q side remains at that position. , The slider block 15 on the arrowhead P side is the moving side base plate
It moves together with 12, and otherwise operates as described above.

In the above description, the case where the drawer 7 is pulled out has been described. However, the drawer 7 can be made to protrude to the opposite side by being pushed. That is, the drawer 7 is held in the housing 20 by the permanent magnet 16.
When a force opposing this magnetic force is applied to the drawer 7 in both cases of pulling out and pushing out, the drawer 7 moves in a desired direction and is pulled out or pushed out.

The embodiment described here is a preferred embodiment of the present invention, and the present invention is not limited to this, and it is needless to say that the present invention can be variously modified and implemented without departing from the gist. . For example, in the present embodiment, the fixed side base plate 11 is detachably attached to the casing 20 and the movable side base plate 12 is detachably attached to the drawer 7, but the fixed side support plate portion 11a is attached to the casing 20. The movable side support plate portion 12a may be formed directly on the outer wall surface of the drawer 7 on the inner wall surface. The fixed rod 13 is supported on the fixed support plate 11a, and the movable rod 14 is supported on the movable support plate 12a.
The slider block 15 may be loosely fitted, and the permanent magnet 16 may be embedded in the slider block 15 so that the slider block 15 and the support plate portions 11a and 12a are magnetically bonded. Since the portions to be magnetically attached are the support plate portions 11a and 12a, the support plate portions 11a and 12a are attached to the housing 20 and the drawer 7 by connecting them with a magnetic material.
The drawer 20 and the drawer 7 can be made of a synthetic resin, a lightweight metal, or the like. Further, the same effect as described above can be obtained even if a magnetic material is embedded in the slider block 15 and the support plate portions 11a and 12a are constituted by permanent magnets.

[0034]

As described above, according to the two-way drawer type drawer according to the present invention, the drawer is locked to the housing using the permanent magnet, so that only a force opposing the magnetic force is applied to the drawer. Can be used to pull out or push out the drawer. For this reason, compared with the structure in which the hook is engaged with the drawer and the drawer is locked to the housing, noise and impact generated when the drawer is pulled out or stored can be reduced. In addition, since it is not necessary to perform the operation of releasing the locking mechanism at the time of drawing or storing, the drawer can be easily inserted and removed. Further, since the drawer and the housing are locked by magnetic force, there is no need for play or the like between them, so that when the drawer is housed, a fixed positional relationship with the housing can be maintained, and the drawer can be mounted in the housing. It does not protrude from the body and impair the beauty.

Further, by supporting the fixed-side guide means with the slide regulating means and supporting the movable-side guide means with the slide drive means, the number of parts is reduced, the structure is simplified, and the weight is reduced. And production cost can be reduced.
