Description

  The present invention relates to a manual waste compressor that can easily compress various types of waste by manual operation of workers, and is particularly suitable for use in compressing medical waste generated in medical facilities such as hospitals and clinics. It can be used.

  In medical facilities, there are many medical wastes such as cotton wool, tissue and plastic used for patient care. These medical wastes are generally used from the viewpoint of hygiene management. It is put out for incineration while still in the trash bin.

  Among the above-mentioned medical waste, absorbent cotton, tissue, etc., which are generated in large quantities, are very bulky when placed in the medical waste trash, so if they are incinerated as they are, many medical waste trash can It is necessary and uneconomical. Therefore, it is conceivable that the medical waste housed in the medical waste trash can be pressed and compressed from above by a worker wearing gloves. Such a compression means is not preferable from the viewpoint of hygiene, and the compression efficiency of medical waste is poor only by pressing it by hand.

  In addition, conventionally, as a means for compressing garbage in a trash box, a garbage compression rod in which a plurality of honeys are rotatably attached to a honey support portion integrally provided at a lower end portion of a rod body has been proposed (for example, Patent Document 1). This garbage compression rod is designed to be used for normal operation when the rod support is pushed down after inserting the honey support section with multiple honey when the trash thrown into the trash is full. Each of the honeys in a downward posture is rotated while being in sliding contact with the upper end surface of the dust and turned sideways, whereby each honey increases the contact area with the dust and functions as a dust pressing portion.

  Furthermore, conventionally, a trash box with a compression function has also been proposed that has a function of manually compressing trash in a trash bag stored in the trash box (see, for example, Patent Document 2). This trash box with a compression function has a pair of link bars provided on the opposite side walls of the trash box body so as to be movable up and down, and the upper ends of both link bars are connected by a handle, and the handle is used to compress trash. For this purpose, a compression plate is connected.

JP 2006-306614 A JP 2001-187601 A

  However, since the dust compression rod of Patent Document 1 swells again with its own restoring force due to the compression of the compressed dust when the pushing operation of the rod body is stopped and the pushing force is released, the dust compression rod is efficiently compressed. I can't. In addition, absorbent cotton and tissue that generate the largest amount of medical waste must be kept compressed for a certain period of time until it is reliably plastically deformed. It is impossible to keep doing. On the other hand, the trash box with a compression function of Patent Document 2 has the same drawbacks as Patent Document 1 during the operation of compressing trash, and the trash box body is integrally provided with a compression function. Cannot be applied to.

  An object of the present invention is to provide a manual waste compressor having a simple structure that can efficiently compress waste by a manual operation of an operator and can be manufactured at low cost.

  In order to achieve the above object, a manual waste compressor according to the first aspect of the present invention is fixed to a mounting plate that is detachably fixed to an open end of a waste container, and is fixed to an upper surface of the mounting plate. A holding frame, a stopper lever whose one fulcrum is rotatably supported by the holding frame, and a sliding lever that is slidably passed through the mounting plate and the insertion holes of the holding frame. A pressing bar that is inserted into the stop hole in a loosely inserted state, and a compression plate that presses and compresses the waste contained in the storage box is provided at the lower end, and an operation bar for pressing operation is provided at the upper end; An elastic member that is interposed between the holding plate and the stopper lever and presses the stopper lever to press the edge of the locking hole against the outer surface of the pressing rod. Yes.

  The manual waste compressor according to claim 2 uses a compression coil spring as the elastic member.

  The manual waste compressor according to a third aspect of the present invention is configured such that the pressing rod is loosely inserted in an auxiliary frame fixed to the lower surface or the upper surface of the holding frame and an insertion hole formed in a storage portion in the auxiliary frame. A compression auxiliary lever integrally having an operation portion penetrating into the insertion state and projecting to the side of the auxiliary frame; and being accommodated in the auxiliary frame in a state of being superimposed on a lower surface of the compression auxiliary lever, A compression auxiliary plate in which the pressing rod is inserted into the hole in a loosely inserted state; and the auxiliary auxiliary frame and the compression auxiliary plate that are interposed between the auxiliary frame and the compression auxiliary plate so that the auxiliary auxiliary plate and the auxiliary compression plate overlap each other. An auxiliary elastic member that applies an urging force that presses against the upper surface of the frame, and when the pressing force is applied to one end of the compression auxiliary lever by the operation unit, the compression auxiliary lever The hole edge portion of the insertion hole of the compression auxiliary lever is pressed against the pressing rod, and the compression auxiliary plate is inclined by pressing one end portion thereof with the inclined compression auxiliary lever. Then, after the hole edge portion of the insertion hole of the compression auxiliary plate is brought into pressure contact with the pressing rod, the compression auxiliary plate and the compression auxiliary lever that move downward by the pressing force to the operation portion are integrated with the compression auxiliary plate. The pressing bar is forcibly moved down.

  A manual waste compressor according to a fourth aspect of the present invention uses a compression coil spring as an auxiliary elastic member in the third aspect of the present invention.

  According to the manual compressor according to claim 1, the mounting plate is fixedly attached to the opening end of the storage box filled with waste, and the stopper lever is rotated to rotate the hole of the locking hole of the stopper lever. With the pressure contact between the edge and the outer surface of the pressing rod released, if the pressing rod is moved downward by applying a pressing force to the operating rod, the compression plate at the lower end of the pressing rod compresses the waste in the storage box. I will do it. Even if the stopper lever is not intentionally rotated, that is, the pressure contact is not released, the pressing rod can be moved downward if the operating rod is pushed down slightly stronger. When the waste can be sufficiently compressed, first, when the depression of the stopper lever is released, the stopper lever 11 automatically returns to the original state by the urging force of the elastic member, and the outer surface of the pressing rod and the locking hole A pressure contact is generated again between the hole edge of the first and second holes. Therefore, even if the pressure bar receives the restoring force of the compressed waste through the compression plate, the upward movement is prevented by the strong friction force generated at the pressure contact, and the waste is compressed by the compression plate. Keep state.

Although this manual waste compressor has a very simple structure and can be manufactured at low cost, it is attached to the storage box, and then the operation bar is pushed down to perform operation inside the storage box. Waste can be easily and efficiently compressed. In particular, when used for compressing medical waste, there is no problem in terms of hygiene. Also, by releasing the operating force on the stopper lever when the compression of the waste is completed, the operating rod can be easily pulled up, and the compression plate and the pressing rod can be moved to the upper limit position, and the storage box Can be easily removed.

  According to the manual waste compressor according to claim 2, since the compression coil spring is held without being displaced by the pressing rod inserted through the inside, the stopper lever is always urged to rotate. be able to.

  According to the manual waste compressor according to the third aspect, the waste can be held in a compressed state after the waste in the storage box is compressed by pushing down the operation rod. In this state, when the operation part of the compression auxiliary lever is pushed down, one end of the compression auxiliary lever provided with the operation part is pushed down, so that the compression auxiliary lever is in contact with the auxiliary frame. By turning the end portion as a fulcrum, it is displaced in an inclined state. The compression auxiliary plate is displaced in an inclined state in which the other end is separated from the compression auxiliary lever by receiving a pressing force from the lower end of the compression auxiliary lever displaced in the inclined state at one end portion thereof. As a result, the hole edge portions of the insertion holes of the compression auxiliary lever and the compression auxiliary plate are pressed against the outer surface of the pressing rod, respectively, and a pressure contact is generated between the compression auxiliary lever and the pressing rod. A pressure contact is also generated between the hole edge of the insertion hole and the pressing rod.

  Therefore, the strong frictional force generated at the two pressure contacts between the compression auxiliary lever and the pressing rod and the two pressure contacts between the compression auxiliary plate and the pressing rod can be used to push down the operation portion of the compression auxiliary lever. Accordingly, the pressing bar is forcibly pushed down integrally with the compression auxiliary lever and the compression auxiliary plate that are moved downward. At this time, the operation force applied to the operation portion protruding to the side of the auxiliary frame is based on the so-called lever principle with the pressure contact between the hole edge of the insertion hole of the compression auxiliary lever and the pressing rod as a fulcrum. It is equivalent to the utilized operating force and is converted into a large pressing force. For this reason, the pressing rod is forced against the biasing force of the elastic member and against the frictional force caused by the press contact between the pressing rod and the stopper lever's locking hole without applying a very strong pressing force to the operation section. Can be moved down. At this time, since the compression assisting plate is in contact with the compression assisting lever only at one end portion, most of the urging force of the elastic member is received by itself. Therefore, since the compression assist lever does not directly receive the biasing force of the elastic member, the lever principle is effectively exhibited when the operation portion is pushed down. Thereby, the waste once compressed by pushing down the operating rod can be further forcibly compressed by the compression assisting lever and the compression assisting plate by operating the operating portion.

  In addition, when the operation force to the operation portion of the compression auxiliary lever is released, the compression auxiliary lever and the compression auxiliary plate are restored to the original state by receiving the restoring force of the elastic member, but the pressing rod is locked to the stopper lever. Since the upward movement is prevented by the friction force generated at the pressure contact with the hole edge of the hole, the waste in the container remains in a state where it is forcibly compressed by the compression auxiliary lever and the compression auxiliary plate. Retained.

  According to the manual waste compressor according to the fourth aspect, the compression coil spring is held without being displaced by the pressing rod inserted through the inside, so that the compression auxiliary lever and the compression holding plate are always securely attached. It is possible to bias the rotation.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a case where the present invention is applied to a use for compressing medical waste, before being attached to a medical waste trash box (hereinafter referred to as a trash can) 10 in a manual waste compressor 1A according to an embodiment. It is a longitudinal cross-sectional view which shows the state. This manual waste compressor 1A has a metal support plate 2 and a mounting plate 3 for fixing to a trash can 10, and these support plate 2 and mounting plate 3 are stacked one above the other in an orthogonal arrangement. The crossing points are fixed to each other by spot welding. Each of the support plate 2 and the mounting plate 3 is applied to the outer surface of the outer flange portion 10a bulging and formed on the outer edge portion of the upper end opening of the trash bin by bending each end portion at a right angle downward. Holding pieces 2a and 3a are formed.

  Clamp members 4 for fixing the mounting plate 3 to the trash bin are mounted on the outer surface of each holding piece 3a at both ends of the mounting plate 3 and in the vicinity thereof. The clamp member 4 includes a claw-like fastener 7 attached to the main body portion in a suspended state, and a fastening operation lever 8 that is rotatably provided on the main body portion. As shown by the arrow, the fastener 7 can be slightly rotated outward from the hanging position. The fastening operation lever 8 functions to lift the fastener 7 by a predetermined height by rotating downward from the illustrated position. The clamp member 4 is not limited to that illustrated in FIG. 1, and may be any member that can hook and fix the mounting plate 3 on the outer flange portion 10 a of the trash can 10, and such a known member can be used. .

  A holding frame 9 having a substantially U-shaped vertical cross section is fixed to the center of the upper surface of the mounting plate 3, and one end of the stopper lever 11 is turnable substantially at the center of the standing wall portion of the holding frame 9. It is locked. Details of the mounting form of the stopper lever 11 will be described later. A pressing rod 12 is penetrated through the center of the support plate 2, the mounting plate 3, the holding frame 9 and the stopper lever 11, and the compression plate 13 and the operation rod 14 are provided at the lower end and the upper end of the pressing rod 12, respectively. However, each center part is being fixed by arrangement | positioning orthogonal to the press rod 12. FIG. In this embodiment, the support plate 2, the mounting plate 3, the holding frame 9, the stopper lever 11, the pressing rod 12, the compression plate 13 and the operating rod 14 are all made of stainless steel, and both the pressing rod 12 and the operating rod 14 are pipes. Thus, weight reduction of the compressor 1 is achieved. A grip portion 17 is provided on both end portions of the operation rod 14 by covering a rubber tube member. A compression coil spring 18 is interposed between the bottom plate portion of the holding frame 9 and the stopper lever 11, and this compression coil spring 18 urges the stopper lever 11 to rotate upward.

FIGS. 2 and 3 are a plan view and a longitudinal sectional view showing the manual waste compressor 1 </ b> A attached to the trash can 10. The manual waste compressor 1A is attached to the trash box 10 with the compression plate 13 pulled up to the upper limit position by the pressing rod 12 when the medical waste charged into the trash box 10 is almost full. The operation of operating the operating rod 14 to pull up the pressing rod 12 and the compression plate 13 will be described later.

  When attaching the manual waste compressor 1A to the trash box 10, the both ends of each of the support plate 2 and the mounting plate 3 are respectively placed in a state where they are bridged over two opposite positions on the opening end face of the trash box 10. The pair of holding pieces 2 a and 3 a of the support plate 2 and the mounting plate 3 are applied to the outer surface of the outer flange portion 10 a of the trash can 10. At this time, when the pair of holding pieces 2a of the support plate 2 is applied to the outer surface of the outer flange portion 10a of the trash box 10, the operation piece 2b formed by bending one holding piece 2a outward and at a right angle is used. By gripping and working, the pair of holding pieces 2 a can be easily applied to the outer surface of the outer flange portion 10 a of the trash can 10.

  On the other hand, in the mounting plate 3 placed in a state where both end portions are bridged to both end portions of the trash box 10, the fastener 7 of the clamp member 4 is in sliding contact with the outer flange portion 10 a of the trash box 10 and is shown by the arrow in FIG. The tip end portion reaches a position below the outer flange portion 10 a while being slightly rotated toward the direction, and the pair of holding pieces 3 a of the mounting plate 3 come into contact with the outer surface of the outer flange portion 10. In this state, when the pair of fastening operation levers 8 of the clamp member 4 are rotated downward from the position shown in FIG. 1 as indicated by the arrows in FIG. 3, the pair of fasteners 7 are pulled up and the tip ends are moved. The trash box 10 is strongly pressed against the lower surface of the outer flange portion 10a. As a result, the manual waste compressor 1A is placed in the trash can 10 with the compression plate 13 hitting the upper end of medical waste (not shown) accumulated in the trash can 10, as shown in FIG. It is firmly fixed.

  As shown in FIG. 3, the plate-like stopper lever 11 is integrally provided with a fulcrum 11a projecting from the center of one end (the left end in the figure). As shown in FIG. 4, which is an enlarged view of the main part of FIG. 3, the fulcrum part 11 a is formed in a shape slightly bent upward with respect to the stopper lever 11. On the other hand, a rectangular slit-shaped support hole 9a having a hole width slightly larger than the thickness of the fulcrum part 11a is formed in the standing wall part of the holding frame 9, and the fulcrum part 11a is loosely inserted into the support hole 9a. ing. Further, a locking hole 11b having a diameter larger than the outer diameter of the pressing rod 12 by a predetermined length is formed in the central portion of the stopper lever 11, and the pressing rod 12 is inserted into the locking hole 11b. .

  Accordingly, the stopper lever 11 is supported rotatably about the fulcrum portion 11a, and is provided with an elastic force upward by the compression coil spring 18, so that the stopper lever 11 is normally in the radial direction of the locking hole 11b. Two opposite edge portions of the hole are held in an inclined posture by being pressed against the outer surface of the pressing rod 12 by a relatively strong biasing force of the compression coil spring 18. Thus, the pressing rod 12 is prevented from moving in the vertical direction by the frictional force generated at the pressure contact P1 between the outer surface of the pressing rod 12 and the two edge portions of the locking hole 11b. If the operating rod 14 is pushed down slightly stronger, the pressing rod 12 can be moved downward without giving the stopper lever 11 a force for releasing the pressure contact with the pressing rod 12. Further, as shown in FIGS. 2 and 3, the mounting plate 3 is provided with high rigidity by a pair of reinforcing pieces 3b formed by bending both side portions in the longitudinal direction upward at right angles. It has high durability against the urging force of the spring 18 and the bending force caused by receiving pressure from below. The pressing rod 12 is slidably inserted into the insertion holes 2c, 3c, and 9b of the support plate 2, the mounting plate 3, and the holding frame 9, respectively.

And when compressing the medical waste accommodated in the trash can 10 in the trash box 10, as shown in FIG. 5, the stopper lever 11 is pushed down until it is positioned almost horizontally, The two pressure contacts P1 with the locking hole 11b are eliminated, and the pressing rod 12 can be freely moved down without being interfered by the stopper lever 11. In this state, the operator operates to grip the grip portions 17 at both ends of the operation rod 14 and push down the operation rod 14. As described above, if the operating rod 14 is pushed down slightly strongly, the pressing rod 12 can be moved downward without depressing the stopper lever 11 (without applying any force).
Thereby, the compression plate 13 compresses the medical waste in the trash box 10 while being pressed down as the pressing rod 12 moves downward.

  When the worker determines that the medical waste has been sufficiently compressed, the worker first releases the depression of the stopper lever 11. Thereby, the stopper lever 11 is automatically returned from the horizontal position in FIG. 5 to the original inclined position in FIG. 4 by the urging force of the compression coil spring 18, and the outer surface of the pressing bar 12 and the edge of the locking hole 11b Two pressure contacts P1 are generated again between the two parts. Therefore, even if the pressing rod 12 receives the restoring force of the compressed medical waste through the compression plate 13, the pressing rod 12 is prevented from moving upward by the strong frictional force generated at the two pressure contacts P1. Thus, the compression plate 13 holds the medical waste in a compressed state.

  The manual waste compressor 1A holds the state in which the medical waste is compressed by the above-described compression plate 13 for a certain period of time, and then rotates the stopper lever 11 to the horizontal position to bring the operating rod 14 to the upper limit position. The clamp lever 4 is lifted and the fastening operation lever 8 is pivoted upward to release the clamp member 4 from the trash box 10 and to remove it from the trash box 10. In this way, if the medical waste in the trash can 10 is compressed and its volume is reduced, a new medical waste is put on the compressed medical waste and the same operation as described above is performed. By repeating, the medical waste accumulated in the upper part of the trash can 10 is compressed.

  Although this manual waste compressor 1A has an extremely simple structure and can be manufactured at low cost, after being attached to the trash box 10, the stopper lever 11 is pushed down to a horizontal position, or By performing the operation of pushing down the operation rod 14 with the stopper lever 11 as it is, the medical waste in the trash can 10 can be compressed easily and efficiently, and when handling the medical waste. There is no problem in hygiene. In addition, when the compression of the medical waste is completed, the medical waste can be reliably held in a compressed state by preventing the compression plate 13 and the pressing rod 12 from moving upward.

  In addition, although the case where it applied to compression of medical waste was illustrated and demonstrated in the said embodiment, 1 A of manual waste compressors of this embodiment were bulky at the time of normal deposition other than medical waste. Although it will be in a state, it can be used suitably also for the use which compresses the other waste which can be easily compressed by the pushing-down force of the operating rod 14.

  FIG. 6 is a longitudinal sectional view of a main part showing a manual waste compressor 1B according to another embodiment of the present invention, and the same or corresponding parts as those in the embodiment are denoted by the same reference numerals, A duplicate description is omitted. In the manual waste compressor 1B, the upper surface of the auxiliary frame 19 having a substantially U-shaped longitudinal section is fixed to the lower surface of the holding frame 9 of one embodiment, and the lower surface of the auxiliary frame 19 is fixed to the upper surface of the mounting plate 3. Has been. On the upper part of the auxiliary frame 19, a compression auxiliary lever 20 and a compression auxiliary plate 21 are horizontally arranged in a state where they are superimposed one above the other. 12 is penetrated in the loosely inserted state and is rotatably supported. An auxiliary compression coil spring 22 is interposed between the compression auxiliary plate 21 and the bottom plate portion of the auxiliary frame 19, and normally, auxiliary compression is performed with the compression auxiliary lever 20 and the compression auxiliary plate 21 being overlapped. The coil spring 22 is pressed against the inner surface of the top plate portion of the auxiliary frame 19 by the urging force of the coil spring 22. At this time, there is a gap between the insertion holes 20 a and 21 a of the compression auxiliary lever 20 and the compression auxiliary plate 21 and the outer peripheral surface of the pressing rod 12.

  The compression assisting lever 20 is integrally provided with an operation part 23 that protrudes largely to the side of the auxiliary frame 19, and the operation part 23 is provided in a slightly inclined and inclined manner. In addition, two strip-shaped reinforcing plates 24 are fixed to the side surfaces of the upper holding frame 9 and the auxiliary frame 9 so as to be bridged.

  Next, the usage pattern and operation of the manual waste compressor 1B according to this embodiment will be described. After being attached to the trash can 10 in the same manner as described in one embodiment, the operation lever 12 is pushed down while the stopper lever 11 is pushed down to the horizontal position, thereby compressing the medical waste in the trash can 10. The pressing force of the stopper lever 11 is released, and the medical waste is held in a compressed state. When the operation rod 12 is pushed down, there is a gap between the insertion holes 20a, 21a of the compression auxiliary lever 20 and the compression auxiliary plate 21 and the outer peripheral surface of the operation rod 12, so that the compression auxiliary lever 20 and the compression assisting plate 21 do not interfere with the pressing operation of the operating rod 12 at all.

  Next, as shown in FIG. 7, when the operation part 23 is pushed down in a state where the medical waste is compressed by the compression plate 13 as described above, one end of the auxiliary compression lever 20 provided with the operation part 23. When the portion is pushed down, the compression auxiliary lever 20 is rotated with the other end portion of the compression auxiliary lever 20 in contact with the top plate portion of the auxiliary frame 19 as a fulcrum, and is displaced in an inclined state. The compression auxiliary plate 21 is displaced into an inclined state in which the other end is separated from the compression auxiliary lever 20 by receiving a pressing force from the lower end of the compression auxiliary lever 20 displaced in the inclined state at one end portion thereof. As shown in FIG. 7, when the operating portion 23 of the compression assisting lever 20 is rotated to a horizontal position, the insertion holes 20 a and 21 a of the compression assisting lever 20 and the compression assisting plate 21 are in the radial direction. The two opposing hole edge portions abut against the outer surface of the pressing rod 12 to form two pressure contacts P2 between the compression assisting lever 20 and the pressing rod 12, and the compression assisting plate 21 and the pressing rod 12 as well. Two pressure contacts P3 are formed between the two.

  When the operation unit 23 that is horizontally arranged in FIG. 7 is further pushed down, as shown in FIG. 8, the two pressure contacts P2 between the compression auxiliary lever 20 and the pressing rod 12 and the compression auxiliary plate 21 The pressing rod 12 is integrally formed with the compression assisting lever 20 and the compression assisting plate 21 that are moved downward along with the pressing operation of the operation portion 23 by the strong frictional force generated at the two pressure contacts P3 between the pressing rod 12 and the pressing rod 12. Will be forced down. At this time, the pressing force applied to the operation part 23 that protrudes largely to the side of the auxiliary frame 19 is a so-called lever principle with two pressure contacts P2 between the compression auxiliary lever 20 and the pressing rod 12 as fulcrums. It is equivalent to the operating force that utilizes, and is converted into a large pressing force.

  Therefore, even if a strong pressing force is not applied to the operation portion 23, it resists the biasing force of the auxiliary compression coil spring 22 and resists the frictional force between the pressing rod 12 and the locking hole 11b of the stopper lever 11. The pressing rod 12 can be forcibly moved down. At this time, the compression assisting plate 21 is in contact with the compression assisting lever 20 only at one end, and almost receives the urging force of the auxiliary compression coil spring 22 only by itself. Therefore, the compression assist lever 20 does not directly receive the urging force of the auxiliary compression coil spring 22, so that the lever principle is effectively exhibited when the operation portion 23 is pushed down.

  As a result, the medical waste in the trash can 10 compressed by pushing down the operating rod 14 can be further compressed by the compression assisting lever 20 and the compression assisting plate 21 by pushing down the operating portion 23. Therefore, the manual waste compressor 1B of this embodiment is suitable when the operation bar 14 cannot be pushed down or is severe. When the pressing force of the operation unit 23 is released, the compression auxiliary lever 20 and the compression auxiliary plate 21 receive the restoring force of the auxiliary compression coil spring 22 and return to the original state of FIG. Since the upward movement is prevented by the frictional force of the contact point P1 with the stopper hole 11b of the stopper lever 11, the medical waste in the trash box 10 is forcibly forced by the compression auxiliary lever 20 and the compression auxiliary plate 21. It is kept compressed.

In particular, it can be suitably applied to the use of compressing medical waste generated frequently in medical facilities, but in addition, it becomes bulky during normal deposition, but it is easily compressed by the pressing force of the operating rod. It can also be suitably used for applications where possible waste is compressed.
