JP5175566B2 - Holder for flow path switching valve and apparatus comprising the same - Google Patents

Description

  The present invention relates to a holder for holding a flow path switching valve and switching the flow path connection of the valve, and an apparatus including the holder.

  Two-way stopcocks and three-way stopcocks are known as means for switching connections between a plurality of flow paths. As shown in FIGS. 1 and 2, the three-way stopcock has three branch pipes 102 a to 102 c connected to the body 101 in a T-shape, and a convex-shaped channel switching tool in the body 101. 106 is a flow path switching valve that is rotatably incorporated and switches the flow paths of the three branch pipes 102 a to 102 c by rotating the flow path switching tool 106. As depicted in FIGS. 2A-D, when the flow path switching device 106 is in the position of FIG. 2A, the flow paths between the branch pipes 102a and 102b, 102a and 102c, and 102b and 102c are all open. In the state of FIG. 2B, only the flow path between the branch pipes 102b and 102c is open. In the state of FIG. 2C, only the flow path between the branch pipes 102a and 102b is open. In the state of FIG. Only the flow path between tubes 102a and 102c opens. The flow path switching tool 106 is provided with a handle 104. By rotating this handle, the flow path switching tool 106 can be rotated to switch the flow path. Although the handle 104 depicted in FIG. 1 has three T-shaped extending arms, a three-way stopcock having a handle having only one arm is also commercially available.

  Such flow path switching means is used in various fields, and one of the fields of use is a drug manufacturing apparatus. The production of a medicine includes a step of mixing or reacting a plurality of liquid or gaseous raw materials, and many steps such as raw material flow, mixing, and purification are performed using many lines. At this time, in order to perform work according to the purpose, a large number of flow path switching valves such as three-way stopcocks are used at branch points of the line. Since it is preferable to minimize contact with the outside during the manufacture of the medicine, the valve switching operation is often configured to be performed by machine control. For this reason, the switching valve has been fixed to a holder connected to a rotating mechanism such as a motor or an actuator, and the flow path has been switched by external control.

  By the way, in the manufacture of pharmaceuticals, in order to prevent contamination of the production line, it is desirable to wash or replace the whole or a part of the production line at the end of production. For this purpose, various manufacturing systems have been devised and put into practical use in which the entire manufacturing line including syringes, tanks, various tubes, switching valves and the like can be attached to and detached from the control device. For example, Japanese Patent Application Laid-Open No. 2004-279192, paragraphs 0026 and 0027 and FIGS. 1 and 2 disclose that the entire production line is integrated into a cartridge, and the entire cartridge is detachable.

  When exchanging the production line, a new production line switching valve needs to be attached to the holder of the control device. At this time, if the mounting is not easy, the switching valve floats from the holder, and not only the production line is not sufficiently fixed, but also the flow path of the switching valve cannot be changed by the rotation of the holder. Moreover, even if it is initially properly attached to the holder, the valve may rise from the holder as the switching operation is repeated, and may be uncontrollable as well.

1 of Japanese Patent Publication No. 8-14344 discloses a drop-off prevention mechanism for fixing the switching valve to the control unit. After the handle 10 of the three-way stopcock 2 is mounted in the hole 10 of the rotary drive unit, (See particularly page 2, right column, line 13 to page 3, left column, line 21 and FIGS. 1 to 3).
Japanese Patent Publication No. 8-14344 JP 2004-279192 A

  However, the dropping prevention mechanism of the Japanese Patent Publication No. 8-14344 takes up space and takes time to attach and detach. In particular, when it is necessary to replace the entire production line as disclosed in Japanese Patent Application Laid-Open No. 2004-279192, the number of switching valves that need to be mounted increases, and the valve is integrated into a drop-off prevention mechanism such as Japanese Patent Publication No. 8-14344. It takes time and effort to attach each one. In addition, since a large number of valves and tubes are densely packed in a narrow range, it may not be physically possible to provide a drop-off prevention mechanism such as Japanese Patent Publication No. 8-14344. Even if it can be provided, The work is expected to be very difficult due to the small space.

  The technology according to the present invention has been developed in view of such circumstances, and has been developed for the purpose of facilitating attachment / detachment of the switching valve and preventing the switching valve from dropping off.

Embodiments of the present invention include a holder for a flow path switching valve that includes a flow path switching handle having at least one arm. This holder is
Having a first position and a second position for receiving the handle, wherein the handle is slidable between the first and second positions;
-In the first position, the flow path switching valve and the holder are separable,
-In the second position, at least one arm of the handle is prevented from separating from the holder, thereby preventing the flow path switching valve from dropping from the holder.
It is comprised so that it may be comprised.

  According to the above configuration, when the switching valve is attached to the holder, the switching valve is simply moved by aligning the switching valve with the holder in the first position, and sliding the valve to the second position. The holder cannot be removed. Also, when removing the valve from the holder, the valve can be separated from the holder by simply sliding the valve from the second position to the first position, so that the valve can be removed with a very simple operation.

  Therefore, according to the above configuration, not only can the switching valve and the holder be attached and detached extremely easily, but also the switching valve can be reliably prevented from falling off the holder.

  Such an easy attachment method is particularly beneficial when a production line assembly including a number of switching valves is attached to the controller. By arranging a holder on the control device side corresponding to the location of the switching valve of the assembly with the sliding directions from the first position to the second position aligned, it is possible to achieve a complicated and large-scale line assembly. Even if it exists, it becomes possible to attach to a control apparatus only by the very simple operation | work of sliding to a 2nd position according to a 1st position.

  As an example of a configuration that inhibits the arm of the handle from being separated from the holder, at least one arm of the handle is accommodated in the groove in the second position, and at least a part of the opening of the groove is partially It is possible to employ a configuration in which a structure for completely or completely closing is provided. Since the arm is housed in the groove, movement of the arm is restricted by being sandwiched by the groove wall, and at least a part of the opening is blocked, so that the arm falls from the opening. Nor. In this way, the valve is prevented from falling off by preventing the arm of the handle from falling off the holder.

  Therefore, an embodiment of the present invention is configured such that when the handle is slid from the first position to the second position, at least one arm of the handle is translated in the same direction as the extending direction thereof. A holder for the flow path switching valve, wherein the at least one arm is housed in the lower portion of the structure in which the baffle plate is provided in the upper portion at the second position, thereby preventing the arm from being separated from the holder. A flow path switching valve holder.

  As an example of a configuration for closing a part of the opening, a baffle plate or a pin passed to at least a part of the upper part of the opening can be employed. In addition, at least a part of the upper portion of the opening may be formed such that the upper portion of the side wall of the groove protrudes toward the center of the opening, thereby partially closing the opening of the portion.

  As another example of a configuration that inhibits the arm of the handle from being separated from the holder, in the second position, at least one arm of the handle is erected on the holder body, and a gate-like structure with a closed upper portion It may be passed through. Even if the arm tries to lift from the holder, it cannot hit the beam because it collides with the beam portion of the portal structure. This prevents the valve from falling off.

  The holder is preferably provided with a structure for supporting the arm of the handle from the side. This is because when the holder rotates to rotate the handle, the arm is pushed to transmit the rotational force to the holder. Accordingly, the first support portion that transmits the rotational force to the handle arm in one rotational direction and the second support portion that transmits the rotational force to the handle arm in the other rotational direction are required. The first support portion and the second support portion may be provided on the same arm of the handle, or may be provided on different arms. These support portions can have a wall-like or columnar structure. It is preferable that the height of the wall surface or the column is set to a height that can sufficiently push the arm.

  When the shape of the handle is T-shaped, each of the two arms corresponding to the T-shaped horizontal bar in the second position is formed so that at least a part thereof is sandwiched by a groove-like or gate-like structure. Is preferred. According to such a shape, when the holder rotates, the rotational force can be effectively transmitted to the handle, and the valve switching operation can be performed smoothly.

  As another example of the configuration that prevents the arm of the handle from being separated from the holder, when the handle is slid from the first position to the second position, at least one of the arms is different from the extending direction of the arm. At least one of the at least one arm in a structure having an opening in the direction of the parallel movement and having a U-shaped cross section in the second position. A configuration in which a part is accommodated can be used. The U-shaped or U-shaped ceiling portion prevents the arm from separating from the holder.

  The embodiment of the holder for the flow path switching valve according to the present invention can have an engaging portion with which at least a part of the shaft portion of the flow path switching valve to be combined with the holder for the flow path switching valve is engaged. For example, when the shaft portion of the bulb is a cylinder, it can have a curved portion into which at least a part of the columnar shape can be fitted. Such an engaging portion is advantageous for positioning the switching valve and the holder in the second position.

  The embodiment of the present invention includes a device in which a flow path switching valve holder embodied by the present invention is rotatably arranged. An embodiment of the present invention is an apparatus in which a plurality of flow path switching valve holders are rotatably arranged, and at least one of the plurality of flow path switching valve holders is embodied by the present invention. A device for a flow path switching valve holder. A typical example of such an apparatus is a drug manufacturing apparatus in which a large number of switching valves are operated to feed and mix raw materials in order to manufacture drugs and the like.

  Some of the preferred embodiments of the present invention are specified in the appended claims. However, the embodiments of the present invention are not limited to those explicitly described in the claims, specification and drawings, and can take various forms without departing from the spirit of the present invention. . The present invention includes in its scope all novel and useful configurations that can be taught from these documents, whether or not explicitly disclosed in the claims, specification and drawings.

  Hereinafter, in order to contribute to a deeper understanding of the present invention, an example of an embodiment of the present invention will be described with reference to the accompanying drawings. First, the external appearance of the three-way stopcock holder 300, which can be a typical example of the embodiment of the present invention, and the usage mode thereof will be described with reference to FIGS.

  3A and 3B are diagrams illustrating the appearance of a three-way cock holder 300 according to the present invention, FIG. 3A is a perspective view, and FIG. 3B is a top view.

  The holder 300 can be manufactured by cutting out a cylindrical member 302. The material of the member 302 is desirably a material that is not easily rusted, such as stainless steel. On the upper surface of the member 302, a valley portion 306 is cut out to form a plateau portion 308 having a substantially semicircular cross section, a plateau portion 310 having a substantially semicircular cross section, and a third plateau portion 312. . As depicted in FIG. 3, the cliff surfaces of the plateau portions 308 to 312 are formed so as to stand vertically from the valley portion 306. Depending on the embodiment, another angle may be used.

  A portion 308a of the cliff surface of the substantially semicircular plateau portion 308 and a portion 310a of the cliff surface of the substantially semicircular plateau portion 310 are formed to face each other in parallel. Therefore, the space surrounded by the cliff surfaces 308a and 310a and the valley portion 306 has a U-shaped groove with a cross section having an opening at the top. One groove of the handle of the three-way cock is accommodated in the groove 314 formed in this way. A baffle plate 316 is passed between the cliff surfaces 308a and 310a, and the opening of the groove 314 is partially blocked. Due to the baffle plate 316, the arm of the handle accommodated in the groove 314 is prevented from coming off from the opening. In FIG. 3, the baffle plate 316 is drawn as an elongated plate-like structure. However, depending on the embodiment, the baffle plate 316 may have a wider plate shape, or conversely, a thin pin-like structure.

  Cliff surfaces 308 b and 310 b where the plateau 308 and plateau 310 are in contact with the circumferential portion of the shaft hole 304 are formed such that the contour seen from above is curved along the circumference of the shaft hole 304. These curved portions are formed in accordance with the shape of the shaft portion of the handle of the three-way cock, and when the handle is attached, the shaft portion fits closely to the curved portions 308b and 310b. As a result, the handle and the holder 300 are positioned. In this example, the contours of the curved portions 308b and 310b are formed in accordance with the circumference of the shaft hole 304. However, it is not important that this contour is made in accordance with the circumference of the shaft hole 304. It should be noted that it is important to make it in accordance with the shape of the shaft part of the stopcock handle.

  A cliff surface 310c orthogonal to a portion 310a of the cliff surface of the substantially quarter-round plateau portion 310 supports the vertical arm of the T-shaped handle from the side surface with the three-way stopcock attached to the holder 300. In other words, the cliff 310a supports one of the two lateral arms of the T-shaped handle from the side. The holder 300 is therefore optimized to hold a three-way stopcock with a T-shaped handle.

The third plateau portion 312 is formed such that a part of the cliff face 312a (see FIG. 3B ) is located in the same plane as the cliff face 310a of the substantially quarter-round plateau portion 310, and a cliff different from 312a. Surface 312b (see FIG. 3B ) is formed to be parallel to cliff surface 310c of plateau 310. The cliff surface 312a supports one side arm of the T-shaped handle from the side when the three-way cock is attached to the holder 300. The cliff face 312b can be used to position the handle arm and the holder 300 at a point in the process of attaching the handle of the three-way cock to the holder 300. A large gap is opened between the cliff surface 310 b of the plateau portion 310 and the cliff surface 312 c of the third plateau portion 312, and a space in which the three-way stopcock can slide is secured on the holder 300.

  The cliff surface 308c located on the opposite side of the cliff surface 308a with respect to the shaft hole 304 in the substantially semicircular plateau portion 308 is slid on the shaft portion when the arm of the handle of the three-way cock slides on the groove portion 314. It is formed parallel to the cliff surface 308a so that the movement is not hindered, and is formed such that the distance between the cliff surface 308c and the center of the shaft portion 304 is at least the same as the radius of the shaft portion of the three-way cock.

  A through-shaft hole 304 may be formed in the central axis portion of the member 302, and this hole can be used for mounting on a rotary actuator of a control device to which the holder 300 is mounted. The hole 304 can also be used to accommodate a part of the shaft portion of the three-way cock.

  FIG. 4 is a diagram schematically illustrating the handle 400 of the three-way cock attached to the holder 300. The handle 400 includes arms 404, 406, and 408 provided in a T shape around a cylindrical shaft portion 402. When the handle 400 is attached to the holder 300 in FIG. 3, the outer edge portion of the shaft portion 402 fits into the cliff surfaces 308b and 310b, and the arm 408 is received in the groove portion 314 described above. The arm 406 is supported from the side by the cliff surface 310c, and the arm 404 is supported from the side by the cliff surface 312a.

FIG. 5 is a view for explaining how the handle 400 is attached to the holder 300. In order to attach the handle 400 to the holder 300, the handle 400 is first received at a position away from the center of the holder 300, as depicted in FIG. In the example of FIG. 5A, the arm 404 and the arm 406 of the handle 400 are in contact with the cliff surfaces 312 a and 312 b of the plateau portion 312, and the upper portion of the shaft portion 402 is in contact with the cliff surface 308 c of the plateau portion 308. The arms 408 of the handle 400 is sandwiched or is only slightly into the groove 314. Thus, the initial position for attaching the handle 400 to the holder 300 can be determined.

  Since the positioning is not necessarily performed at the initial position, it is not necessary that the arm 404 and the arm 406 are in contact with the plateau 312 as shown in FIG. 5A at the start of the mounting operation, and the arm 408 is in contact with the baffle plate 316. It is sufficient if the handle 400 can be attached to the holder 300 so that it does not occur.

  As illustrated in FIG. 5A, at the start of the mounting operation, a structure that firmly prevents the handle 400 from moving above the holder 300 is not provided, so that the handle 400 can be freely detached from the holder 300. It is possible. However, depending on the embodiment, by making the width of the groove 314 slightly narrow, for example, resistance is applied when the arm 408 is pulled out of the groove 314, so that a slight holding force is exerted on the handle 400 even in the state of FIG. 5A. You may comprise so that it can do.

  To attach the handle 400 to the holder 300, from the state of FIG. 5A, the handle 400 is slid rightward in the drawing, that is, along the groove 314 from the center to the outside. When the shaft portion 402 of the handle comes into contact with the cliff surfaces 308b and 310b, the sliding of the handle 400 is stopped, and the positioning of the handle 400 and the holder 300 is performed. The state at this time is depicted in FIG. 5B.

  In the state of FIG. 5B, the arm 408 is completely accommodated in the groove portion 314, and both side surfaces thereof are supported by the cliff surfaces 308a and 310a. Further, since the arm 408 is passed through the lower side of the baffle plate 316, the baffle plate 316 cannot be removed from the groove portion 314 due to the baffle. The distance between the cliffs 308a and 310a and the baffle plate 316 and the arm 408 must be appropriately determined in accordance with specific requirements in mounting. If the distance between the cliffs 308a and 310a or the baffle plate 316 and the arm 408 is virtually zero, the arm 408 is held very firmly by these. Conversely, if there is a margin in the above-described interval, some play of the arm 408 will be allowed in the groove 314. It should be noted that the embodiments of the present invention include any of them.

  The outer peripheral surface of the handle shaft 402 abuts against the curved cliff surfaces 308b and 310b, thereby aligning the handle and the holder. The arm 406 is supported from the side by the cliff surface 310c, and when the holder 300 is rotated in the direction of the arrow 502, the arm 406 is pushed by the cliff surface 310c and receives the rotational force to rotate the handle 400. The arms 404 and 408 are also supported from the side by the cliff surfaces 312a and 308a, respectively, and similarly receive the rotational force when the holder 300 is rotated in the direction of the arrow 502. When the holder 300 is rotated in the direction of the arrow 504, the rotational force of the holder 300 is transmitted to the handle arm 408 via the cliff surface 310a. It is preferable that the heights of the cliff surfaces 308a, 310a, 310c, and 312a are set to heights that can transmit sufficient force to the arms when the arms 404, 406, and 408 are pushed.

  As described above, in the state of FIG. 5B, the baffle plate 316 prevents the arm 408 from being detached from the groove 314, so that the handle 400 can be prevented from falling off the holder 300. Therefore, the three-way stopcock can be attached to the holder 300 simply by pressing the handle 400 against the holder 300 at the position depicted in FIG. 5A and sliding the three-way stopcock together with the handle 400 to the position depicted in FIG. 5B. it can. Therefore, the three-way cock can be attached to the holder by a very simple operation, and the three-way cock can be prevented from falling off.

  FIGS. 5C to 5E show a modified example 301 of the holder 300 so that the rotational force can be reliably transmitted by the handle 400 when the holder 300 rotates. About the same element as FIGS. 3-5B, the same code | symbol as these figures is attached | subjected and description is abbreviate | omitted. The holder 301 is different from the holder 300 in that a portion of the plateau portion 308 facing the plateau portion 312 protrudes toward the plateau portion 312. Other parts are the same as those of the holder 300.

  The protruding portion 308d is provided so as to support the arm 404 on the cliff face from the side when the handle 400 is accommodated (see FIG. 5E). When the holder 300 rotates in the direction of the arrow 504, the only part that transmits the rotational force to the handle 400 is the cliff surface 310a. However, the holder 301 is not only the cliff surface 310a but also the cliff surface of the protruding portion 308d ( Since the rotational force can be transmitted to the handle 400 (by pressing the arm 404), the rotational force can be transmitted more reliably than the holder 300.

  Further, since the protruding portion 308d is provided only in a portion facing the plateau portion 312, a sufficient space for receiving the shaft portion 402 is ensured in the initial stage of the attaching operation of the handle 400 (see FIG. 5D).

When attaching the handle 400 to the holder 301, first, as shown in FIG. 5D, the handle 400 is received by the holder 301 so that the arm 408 does not contact the baffle plate 316. Next, the handle 400 is slid in the direction of the groove 314 until the shaft portion 402 of the handle comes into contact with the plateau portions 308 and 310 (see FIG. 5E). FIGS. 5D and 5E are views of FIG. And corresponds to FIG. 5B. In the state of FIG. 5D, since there are no components of the holder 301 above the handle 400, the handle 400 and the holder 301 are detachable. In the state of FIG. 5E, since the baffle plate 316 exists above the arm 408, the arm 408 cannot be lifted from the groove 314, thereby preventing the handle 400 from falling off the holder 301. As with the attachment to the holder 300 , the attachment of the handle 400 to the holder 301 can be performed simply by sliding the handle from a position where it can be detached from the holder to a position where it can be prevented from falling off. .

  The holder 300 can be used in an apparatus as depicted in FIG. The apparatus 700 is a control apparatus for controlling the drug production line assembly 600 as depicted in FIG. The outline of the chemical production line assembly 600 will be described first. The assembly 600 includes a plurality of three-way stopcocks 602a to 602f, a plurality of syringes 604a to 604d, a plurality of containers 606a and 606b, a heater 608, a plurality of piping tubes 610a and 610b, and the like. Is provided. By the time the raw material flowing in from the piping tube 610a reaches the container 606b, elements such as a three-way stopcock and a syringe are appropriately controlled to perform a predetermined mixing / reaction to produce a chemical. The chemical production line assembly 600 described here is a very general / abstract description of its function and structure, and the actually used line assembly is much more complicated. Can do.

  The control device 700 to which such a chemical production line assembly 600 is attached includes three-way stopcock holders 702a to 702f corresponding to the positions of the three-way stopcocks 602a to 602f, syringe holders 704a to 704d for fixing the syringes 604a to 604d, and Actuators 706a to 706d for operating the syringes 604a to 604d are included. The three-way stopcock holders 702a to 702f are arranged to be independently rotatable, and switch the flow paths of the three-way stopcocks 602a to 602f in accordance with the prescription for manufacturing medicines. The control device 700 described here also has a very general and abstract description of its function and structure, similar to the chemical production line assembly 600 described with reference to FIG. The control device used can be much more complex than this.

  In the control device 700, at least one of the three-way cock holders 702a to 702f is the three-way cock holder 300 depicted in FIGS. The three-way stopcock dropping prevention function of the three-way stopcock holder 300 prevents the entire three-way stopcocks 602a-f from dropping out during the operation of the control device 700. All three-way stopcock holders 702a-f may be three-way stopcock holders according to the present invention, but only some of them may be three-way stopcock holders according to the present invention. Since the three-way stopcocks 602a to 602f are connected and integrated with each other, if one of the three-way stopcocks is prevented from falling off, the adjacent three-way stopcock is also prevented from dropping out, so that only a part of the holders according to the present invention Even in the case of the stopcock holder, the entire three-way stopcock row can be prevented from falling off. According to the result of the trial production, one of the five holders may be a holder according to the present invention, and even if it is desired to attach the three-way stopcock more reliably, one of the three holders may be used. However, the holder for attaching the three-way cock located at the end of the row is preferably a holder according to the present invention. In the control device 700, only the three holders 702a, 702d, and 702f are the three-way cock holder 300 according to the present invention, and the other holders do not have the function of preventing the three-way cock from falling off. This alone can sufficiently prevent the three-way stopcocks 602a-f from falling off the holders 702a-f.

  When the line assembly 600 is mounted on the control device 700, first, the arms of the three-way cocks 602a-f are all aligned in the same direction, and the holders 702a-f are also aligned in the same direction. Adjust so that it is drawn. Then, while pressing the line assembly 600 against the control device 700, the corresponding three-way stopcock and holder are slid to the positions depicted in FIG. 5B. With this operation, as shown in FIG. 5B, one arm of the handle of the three-way cock enters the area surrounded by the groove 314 and the baffle plate 316, and the handle is hindered by the baffle plate 316 and the handle floats from the holder. This prevents the 602a-f from floating or falling off the holders 702a-f.

  In a chemical production line assembly, three-way stopcocks are generally directly connected without a tube in order to minimize dead volume. Accordingly, the interval between the three-way stopcocks is narrowed, and the interval between the holders is inevitably narrowed, and providing the holder with a drop-off prevention mechanism as depicted in FIG. Space is difficult. Moreover, since the space | interval between three-way cocks is narrow, the space which can put a hand and work can be small, and it is also difficult to operate a drop-off prevention mechanism by hand with respect to each one-way cock. However, according to the three-way stopcock holder of the present invention, the three-way stopcock assembly can be slid only from the first position where the three-way stopcock is separable to the second position where the handle of the three-way stopcock is prevented from being detached. Can be fixed to the holder. It should be noted that in the example line assembly 600 described above, only six three-way stopcocks were depicted, but in practice it is not uncommon to have more than ten three-way stopcocks. . Therefore, the ease of mounting realized by the present invention is a great advantage in actual mounting.

  FIG. 8 is a diagram depicting a state in which the line assembly 600 is mounted on the control device 700. In addition to the three-way stopcocks 602a-f being attached to the holders 702a-f, the syringes 604a-d are fixed to the syringe holders 704a-d, thereby preventing the entire line assembly 600 from falling off the control device 700. Is done. Further, since the three-way stopcocks 602a to 602f are connected to each other, even if the handle of these three-way stopcocks is rotated by the holder 702, the main body of the three-way stopcock does not rotate. Switching can be done. In addition to the illustration, a mechanism for fixing the main bodies of the three-way cocks 602a to 602f to their handles and a mechanism for securely fixing the line assembly 600 to the control device 700 can be provided.

  Next, some other embodiments of the three-way stopcock holder according to the present invention will be described with reference to FIGS.

  FIG. 9 and FIG. 10 are views for explaining a second embodiment of the three-way cock holder according to the present invention, and are diagrams depicting the main points of the three-way cock holder 300 ′ according to the second embodiment. . In the figure, the same structure as the holder 300 is denoted by the same reference numeral as in FIG.

  Referring first to FIG. 9A, the holder 300 ′ also has plateau portions 308 ′ and 310 ′ corresponding to the plateau portions 308 and 310 of the holder 300. Unlike the holder 300, the groove 314 ′ between the plateau portions 308 ′ and 310 ′ is not provided with a structure such as a baffle plate 316 passed from the plateau portions 308 ′ to 310 ′. Instead, in the portion close to the edge of the holder 300 ′, the plateau portions 308 ′ and 310′a which become the groove walls of the groove 314 ′ and the upper portions 308′a and 310′a of the cliff surface of the groove 314 ′ block the opening of the groove 314 ′. As shown, it protrudes toward the center of the groove 314 ′. Except for these structural differences, the holder 300 and the holder 300 'have the same structure.

  9B is a cross-sectional view taken along the line XX ′ of FIG. 9A, and FIG. 9C is a cross-sectional view taken along the line YY ′ of FIG. 9A. As can be seen by comparing FIG. 9B and FIG. 9C, because of the protruding portions 308′a and 310′a, the width of the opening of the groove 314 ′ is narrower on the peripheral side than on the center side of the holder. Yes. Then, the arm of the handle of the three-way cock accommodated in the groove 314 ′ is obstructed by the protruding portions 308′a and 310′a and is prevented from coming off from the opening of the groove 314 ′.

  FIG. 10 is a view for explaining how the handle 400 of the three-way cock in FIG. 4 is attached to the holder 300 ′. FIG. 10A is a diagram depicting a state in an initial stage when mounting is performed. In the state of FIG. 10A, the holder 300 ′ receives the handle 400 at a position away from the center, the arm 404 and the arm 406 of the handle 400 are in contact with the cliff surface of the plateau 312, and the arm 408 of the handle is the groove 314. 'It is inserted a little in the part near the center of the holder. As in the case of the holder 300 previously described with reference to FIG. 5A, in the state of FIG. 10A, a structure for preventing the handle 400 from being separated from the holder 300 ′ is not provided, and the handle 400 and the holder 300 ′ are not provided. Are separable. That is, the opening of the groove 314 ′ must be formed in a size that allows the arm 408 to enter in a portion near the center of the holder.

  10A, when the handle 400 is slid along the groove 314 ′, the state depicted in FIG. 10B is obtained. In the state of FIG. 10B, the handle arm 408 is received in the groove 314 ′, and the protruding portions 308′a and 310′a prevent the arm 408 from being removed from the opening of the groove 314 ′. This prevents the handle 400 from falling off the holder 300 ′. 10C and 10D are a cross-sectional view taken along the line XX ′ and a cross-sectional view taken along the line YY ′ of FIG. 10B, respectively. 10C and 10D, at the end of the groove 314 ′, the upper portion of the handle arm 408 is partially covered by the protruding portions 308′a and 310′a, and the handle arm 408 is open to the groove 314 ′. It turns out that it is impossible to remove from the part.

  Accordingly, the three-way cock is attached to the holder 300 ′ by first pressing the handle of the three-way cock to the holder 300 ′ so as to be in the state of FIG. 10A, and then sliding the three-way cock to the state of FIG. 10B along the groove 314 ′. Can only be done. In the state of FIG. 10B, the arm of the handle is prevented from being lifted from the groove 314 ′, so that the three-way cock is prevented from being displaced from the holder 300 ′ or falling off. That is, the holder 300 ′ has the same advantages as the above-described holder 300 that enables the three-way stopcock to be attached to the holder with a very simple operation, and reliably prevents the three-way stopcock from falling off.

  FIGS. 11 and 12 are views for explaining a third embodiment of the three-way cock holder according to the present invention, and are diagrams illustrating the main points of the three-way cock holder 300 ″ according to the third embodiment. In the figure, the same structure as the holder 300 is denoted by the same reference numeral as in FIG.

  Reference is first made to FIG. The feature of the three-way cock holder 300 "according to the third embodiment with respect to the three-way cock holder 300 according to the first embodiment is that the T-shaped handle of the platform portion 310" corresponding to the platform portion 310 of the holder 300 is used. That is, the upper part of the portion that supports the vertical arm from the side faces the direction of the valley portion 306. Due to the protruding portion 310 "c, the shape of the portion that supports the vertical bar of the T-shaped handle has a lateral groove shape with a U-shaped cross section having an opening in the lateral direction. The three-way cock is a holder 300" The vertical bar of the T-shaped handle is accommodated in a lateral groove portion 1102 surrounded by the protruding portion 310 ″ c, the plateau portion 310 ″, and the valley portion 306. The structure of the holder 300 ″ is the same as the structure of the holder 300 described above, except for the structure related to the lateral groove 1102.

  Next, a state where the handle 400 of the three-way cock shown in Fig. 4 is attached to the holder 300 "will be described with reference to Fig. 12. Fig. 12A is a diagram depicting an initial stage state when the attachment is performed. In the state, the handle 400 is received at a position away from the center in the holder 300 ". The arm 406 of the handle is accommodated in the holder 300 ″ through the gap between the base plate portion 312 and the protruding portion 310 ″ c, and the arm 408 is inserted slightly into the portion of the groove portion 314 near the holder center. As in the previous embodiment, in this state, the handle 400 and the holder 300 "must be separable. Therefore, the extent of the protrusion 310" is determined by the platform 312 and the protrusion 310 "c. It must be determined that the handle arm 406 can sufficiently enter the gap.

  When the handle 400 is slid along the groove 314 from the state of FIG. 12A, the state depicted in FIG. 12B is reached, and the arm 406 of the handle is received in the lateral groove 1102. In the state shown in FIG. 12A, the protruding portion 310 "c covers (at least a part of) the upper portion of the arm 406, so that the arm 406 cannot be lifted from the holder 300". This situation is well represented in the arrow view of FIG. 12B. Since the arm 406 is restrained by the protruding portion 310 "c, the handle 400 is prevented from being lifted from the holder 300" and falling off.

  As in the case of the holder 300, the holder 300 ″ prevents the arm 408 from floating from the opening of the groove 314 by the baffle plate 316. That is, the holder 300 ″ is added to the handle drop-off prevention mechanism of the holder 300. In addition to the holder 300, the three-way stopcock can be more reliably prevented from being lifted or dropped because the additional handle drop-off preventing mechanism is provided by the protruding portion 310 "c.

  Further, the three-way stopcock is attached to the holder 300 "so that the handle of the three-way stopcock enters the holder 300" through the opening of the holder 300 "first, and then the state shown in FIG. 12B is obtained. The three-way stopcock can be completed simply by sliding along the groove 314 until the handle shaft 402 abuts the plateau 308 and 310 ". That is, the holder 300 ″ also has the advantage that the three-way cock can be attached with a simple operation, like the three-way cock holder according to the above-described embodiment.

  As a further modification of the embodiment of FIGS. 11 and 12, an embodiment without the baffle plate 316 is also included in the scope of the present invention. Such an embodiment is depicted in FIG. 12C. 12B and 12C, it can be seen that the three-way stopcock holder 300 "'according to the embodiment of FIG. 12C is not provided with the baffle plate 316. However, in the embodiment like the holder 300"' However, since the upward movement of the arm 406 (see FIG. 12B) of the handle is hindered by the protruding portion 310 ″ c, it is possible to prevent the three-way stopcock from dropping from the holder 300 ″ ′. Further, since the three-way stopcock can be attached to the holder 300 "'in the same manner as described with reference to FIGS. 12A and 12B, it has the same advantage as the above-described holder 300 and holder 300" that is easy to attach. Yes.

  Next, a fourth embodiment of the three-way stopcock holder according to the present invention will be described with reference to FIG. FIG. 13A is a top view of a three-way stopcock holder 1300 according to the fourth embodiment. Unlike the holder 300 according to the above-described embodiment, the holder 1300 does not have a plateau portion on the upper surface portion 1302, and the upper surface portion 1302 has a simple planar shape. Instead, at least six pins 1304 a to 1304 f are erected on the upper surface portion 1302.

  These pins 1304a to 1304f are provided to support the horizontal arm of the T-shaped handle of the three-way cock. The pins 1304a and 1304b are supported by sandwiching one of the two horizontal arms, and the pins 1304c and 1304d and the pins 1304e and 1304f are supported by sandwiching the other of the horizontal arms. Therefore, the pins 1304a, 1304c, and 1304e are arranged on a straight line, and the pins 1304b, 1304d, and 1304f are arranged on a straight line. The pins 1304a and 1304b are provided on one side with respect to the shaft hole 1301 similar to the shaft hole 304 of the holder 300, and the pins 1304c to 1304f are provided on the other side. The pins 1304a and 1304b and the pins 1304e and 1304f are erected near the edge of the upper surface portion 1302, but the pins 1304c and 1304d are erected on the center side of the upper surface portion 1302, and are attached to the shaft portion of the handle of the three-way cock. It is also used for abutting and positioning the handle and the holder. The top of the pins 1304e and 1304f is passed with a pin 1306. Therefore, the pins 1304e, 1304f and 1306 have a gate-like shape with the top closed, and the pin 1306 can be said to be a gate beam.

  Next, with reference to FIGS. 13B and 13C, how the handle 400 of the three-way cock in FIG. 4 is attached to the holder 1300 will be described. When attaching the handle 400 to the holder 1300, first, as depicted in FIG. 13B, the handle arm 404 is sandwiched between the pins 1304a and 1304b, and the handle arm 408 is sandwiched between the pins 1304c and 1304d. The handle 400 is positioned. In this state, since there is no structure for preventing the handle 400 from being detached from the holder 1300, the handle 400 and the holder 1300 can be separated.

  Next, the handle 400 is slid in the direction of the pins 1304e and 1304f so as to be guided by these pins 1304a to 1304d, and is stopped when the shaft portion 402 of the handle contacts the pins 1304c and 1304d. The positional relationship between the handle 400 and the holder 1300 is now in the state depicted in FIG. 13C. In the state of FIG. 13C, the arm 408 of the handle is passed through the portal structure formed by the pins 1304e, 1304f, and 1306. Therefore, even if the arm 408 is to be detached from the holder 1300, the beam pin 1306 is obstructed and cannot be detached. This prevents the handle 400 from being lifted or dropped from the holder 1300.

  The three-way stopcock can be attached to the holder 1300 simply by sliding the handle 400 from the state depicted in FIG. 13B to the state depicted in FIG. 13C, so that the three-way stopcock can be attached with a simple operation. It also has the advantage of the three-way stopcock holder according to all the previous embodiments that it is possible.

  As seen in FIG. 13C, the pin 1304a pushes the handle arm 408 from the side to transmit the rotational force to the handle 400 when the holder 1300 rotates in the direction of the arrow 1310. Similarly, the pins 1304 d and 1304 f push the arm 404 of the handle from the side when the holder 1300 rotates in the direction of the arrow 1310, and transmit the rotational force to the handle 400. When the holder 1300 rotates in the direction of the arrow 1312, the pins 1304b, 1304c, and 1304e push the arms 404 and 408 to rotate the handle 400, respectively. Therefore, it is preferable that the height of the pins 1304a to 1304f is set to a height that can sufficiently push the arms 404 and 408.

  Finally, an example of an embodiment of the present invention suitable for a three-way stopcock having only one handle arm will be described with reference to FIG.
