Description

  The present invention relates to a tap locking mechanism for dispensing liquid from a dispenser.

  In restaurants such as beer halls, beer servers that pour barreled beer into containers such as mugs are used. A staff member of a restaurant such as a beer hall operates a lever provided at the top of a tap provided in the beer server to pour beer into a mug. In a posture in which the lever stands upright on the top surface of the tap (hereinafter, this posture may be referred to as a “neutral posture”), beer is not poured from the tap spout, and the posture is inclined forward from the neutral posture. When the lever is knocked down, beer is poured from the spout of the tap. When the lever is tilted so as to be inclined backward from the neutral posture, the foam is poured out from the foam spout arranged in the vicinity of the beer spout.

  By the way, in restaurants where store space is limited, a beer server may be installed in a narrow place such as the side of a passage where staff frequently visit. In such a case, if the staff's body comes into contact with a lever in a neutral posture and the lever moves, there is a high possibility that beer leaks from the spout.

  In order to prevent the occurrence of such a situation, for example, in Patent Document 2, the engaging portion of the connecting tool attached to the lever of the water faucet is fitted into the lock groove of the hook provided in the container body, A lever-type water faucet locking device that supports a tool in a substantially horizontal state is disclosed. In the lever-type water faucet locking device described above, a lock groove for supporting a connector attached to the lever must be provided on the front surface of the container body. If such a structure is a box-shaped beer server as described in Patent Document 1, it can be applied to a front panel to which a tap is attached. However, for example, in the case of a stand-type tap mounted upright on the counter, there is no place to attach the hook near the lever of the tap. In such a case, the structure as described above cannot be taken, and there is no versatility.

  The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a tap lock mechanism that can prevent liquid leakage with a simple structure and has high versatility.

  In order to solve the above problems, the present invention has a tap body, one end accommodated in the tap body, and the other end facing the one end and positioned outside the tap body, and passes through the vicinity of the one end.

The thickness of the shaft portion 10b is such that, when the lever 10 (operation portion 10a) is operated, one end B is not in contact with the outer peripheral end of an opening 143 to be described later of the pedestal 14 and around the rotation axis passing near the one end B. So that the other end T (hereinafter referred to as “the other end”) that is opposed to can be rotated within a predetermined angular range (in this embodiment, the other end T side is indicated by the arrows F and R in the front-rear direction). Can be set as appropriate. In addition, as the shape of the shaft portion 10 b on the end portion B side, a shape that can accommodate the shaft portion 10 b on the end portion B side in the tap body 13 can be appropriately set. The shaft portion 10b may be made of, for example, a metal material such as stainless steel, may be made of a material other than the metal material, and may be made of, for example, a resin material.

  The lever 10 (shaft portion 10b) is operatively attached to the tap body 13 via the base 14 and the attachment portion 134. As shown in FIG. 1A, the lever 10 is attached to the tap body 13 with the operation unit 10 a standing upright with respect to the tap body 13. As described above, in this posture, beer is not discharged from the discharge port 131, and foam is not discharged from the foam outlet 132. A known structure can be appropriately set as the internal structure of the tap body 13 that can operate the lever 10 with respect to the tap body 13.

  When discharging beer from the discharge port 131, the lever 10 is operated so that the other end T of the lever 10 (operation unit 10a) rotates forward as indicated by an arrow F, as shown in FIG. do it. When foam is poured out from the foam outlet 132, as shown in FIG. 1C, the other end T of the lever 10 (operation unit 10a) is located behind the rear of the beer server casing (indicated by an arrow R). The lever 10 may be operated so as to rotate to the front side.

  The tap lock mechanism 5 in the present embodiment has a cylindrical lock portion 12 as a configuration for switching between a fixed state in which the lever 10 is fixed so as to be inoperable and a fixed release state in which the fixation is released. A holding unit 11 and a pedestal 14 are provided. In the present embodiment, the “fixed state” refers to a state in which the lock unit 12 and the pedestal 14 are in contact with each other while the lock unit 12 is in contact with the holding unit 11 so that the lever 10 cannot be operated. The “unlocked state” means a state in which the lock portion 12 is brought into contact with the pedestal 14 so that the lever 10 can be operated, or a state in which the lock portion 12 and the pedestal 14 are separated from each other. Say. In the “unlocked state” in the present embodiment, the lock portion 12 is in contact with the holding portion 11 to the extent that the lock portion 12 can be operated. Hereinafter, the tap lock mechanism 5 will be described in detail.

  As shown in the plan view of FIG. 2 (F), the pedestal 14 in this embodiment has a substantially disk shape in plan view and has an opening 143 at the center. Further, as shown in the side view of FIG. 2 (E), the pedestal 14 is formed with a convex portion 14P projecting upward from the disc-shaped portion 14D in a side view, on the upper portion of the disc-shaped portion 14D. As shown in FIG. 2 (F), the outer diameter of the convex portion 14P is smaller than the outer diameter of the disk-shaped portion 14D. Further, the flat surface from the outer peripheral end of the convex portion 14P to the outer peripheral end of the disc-like portion 14D is a mounting surface 142 on which the convex portion 121 described later is placed. An inclined surface 144 is formed from the outer peripheral end of the convex portion 14P to the inner peripheral end (the outer peripheral end of the opening 143). As shown in FIG. 2E, the opening 143 is a through-hole penetrating from the convex portion 14P to the disc-like portion 14D.

  As shown in FIG. 2 (F), the outer wall surface 145 of the disk-shaped portion 14D is formed with two recesses 141 arranged to face each other so as to be recessed inward from a desired position of the outer wall surface 145. . A convex portion 121 described later is fitted into the concave portion 141. Note that the shape of the pedestal 14 is not limited to a disk shape in plan view, and may be, for example, a polygonal shape such as a square shape or a hexagonal shape in plan view.

  The opening part 143 is formed so that the opening diameter is larger than the outer diameter of the shaft part 10b. Thereby, since a gap is formed between the outer peripheral end of the opening of the opening 143 and the outer wall of the shaft portion 10b, the lever 10 can be operated so that the other end T of the lever 10 rotates forward and backward. Such a base 14 is attached to the tap body 13 around the shaft portion 10b on the tap body 13 side. Note that the tap 1 in the present embodiment supports the lever 10 (shaft portion 10b) in a space in the tap body 13 disposed below the opening 143 of the pedestal 14 so as to be operable, for example, a spacer. (Not shown) is provided.

  In addition, in this embodiment, although the mounting surface 142 is formed in all except the part in which the recessed part 141 was formed among the upper periphery of the base 14 (disk shape part 14D), it is not limited to this. For example, a narrow mounting surface may be formed on a part of the upper peripheral edge of the pedestal 14. In this case, most of the peripheral area of the pedestal 14 is in the form of a recess 141. That is, the region in which the concave portion 141 is formed and the region in which the mounting surface 142 are formed in the present embodiment are reversed, and the wide concave portion 141 and the narrow mounting surface 142 are alternately arranged on the periphery. It is good also as the base 14 of a simple structure. That is, when such a pedestal 14 is viewed from above, the two mounting surfaces 142 facing each other are projected from the outer periphery of the inclined surface 144 (convex portion 14P).

  As shown in FIGS. 2C to 2F, the outer diameter of the pedestal 14 (disk-shaped portion 14D) is set so that the inner wall of the lock unit 12 can come into contact with the outer wall of the pedestal 14. The inner surface of the pedestal 14 (opposite to the outer wall surface of the disk-shaped portion 14D) is attached to the mounting portion (the mounting portion 134 so that the pedestal 14 is attached to the mounting portion 134 of the tap body 13). (Not shown) is formed. The attached portion can be formed by, for example, providing the inner wall surface with a screw thread that is screwed into a screw thread provided on the outer wall surface of the attachment portion 134. The thickness of the pedestal 14 can be appropriately set in consideration of the region for forming the attached portion as described above.

  As shown in FIGS. 2 (A) to 2 (B), the holding portion 11 has a cylindrical shape, and the outer diameter of the lock portion 12 can be brought into contact with an inner wall of a cylindrical lock portion 12 described later. It is substantially the same as the inner diameter, and its height is substantially the same as the height of the lock portion 12. The inner wall surface of the holding part 11 is formed with an insertion hole 110 through which the central part 10b of the lever 10 is inserted. The holding portion 11 is not limited to a cylindrical shape, and may be, for example, a rectangular tube shape. However, the shape corresponding to the shape of the lock portion 12 is such that the lock portion 12 can be slidably fitted. It can be set appropriately.

  The insertion hole 110 is configured by a screw hole 110s in which a thread is provided on the inner wall surface of the holding portion 11, and a sliding hole 110t continuous to the screw hole 110s. That is, the insertion hole 110 is a through hole that penetrates the holding portion 11 in the axial direction. The screw thread provided in the screw hole 110s is for screwing the holding part 11 to the shaft part 10b of the lever 10, and the screw thread screwed into the screw thread is provided on the outer wall surface of the shaft part 10b. ing. The sliding hole 110t has a substantially truncated cone shape in which the diameter of the opening hole on the lower end side of the holding portion 11 is larger than the diameter of the screw hole 110s. That is, a tapered inclined surface 111 is formed in the sliding hole 110t from the opening end on the lower end side of the holding portion 11 to the opening end on the lower end of the screw hole 110s. The inclined surface 111 is formed so as to substantially contact the inclined surface 144 of the pedestal 14 when the holding portion 11 is placed on the upper portion of the pedestal 14. Thus, when the lever 10 (the other end T) is tilted forward as indicated by the arrow F or backward as indicated by the arrow R, the inclined surface 111 and the inclined surface 144 are slid relative to each other, thereby It can be operated smoothly.

  Further, the holding part 11 is formed with a tapered inclined surface 112 from the outer peripheral edge of the opening hole on the lower end side to the outer peripheral edge at the lower end of the outer wall surface 113 of the holding part 11. The inclined surface 112 functions as a locking portion for locking a convex portion 121 provided on the lock portion 12 described later.

  The tap lock mechanism 5 in the present embodiment is configured such that the outer diameter of the holding portion 11 and the outer diameter of the base 14 are substantially the same. This is required to bring the inner wall surface 122 of the lock portion 12 into contact with the outer wall surface 113 of the holding portion 11 and the outer wall surface 145 of the pedestal 14 in order to act on the lock function described later of the tap lock mechanism 5 in the present embodiment. Because there is.

  In the present embodiment, the holding part 11 and the lever 10 are configured separately, but the present invention is not limited to this. For example, the shaft part 10b of the lever 10 and the holding part 11 are configured integrally. It may be. In such a case, since the shaft portion 10b assumes the function of the holding portion 11, as a configuration for enabling switching between the “fixed state” and the “fixed release state”, the tap lock mechanism 5 includes at least the lock portion. 12 and pedestal 14 may be provided. In the present embodiment, the height of the holding portion 11 is a height that fits between the lower portion of the operation portion 10a and the upper portion of the pedestal 14 (disk-like portion 14D), and can be provided around the shaft portion 10b. However, it is not limited to this. For example, without providing the operation unit 10a, the outer wall (height) of the holding unit 11 is extended from the upper portion of the base 14 to a position corresponding to the operation unit 10a of the lever 10, and the holding unit 11 also serves as the operation unit 10a. It may be a structure.

  As shown in FIGS. 2C and 2D, the lock portion 12 has a cylindrical shape, and the inner diameter thereof is substantially the same as the outer diameter of the holding portion 11. It is formed so that the outer wall surface 113 of the holding part 11 contacts. Accordingly, the lock portion 12 can be moved up and down indicated by the arrow UD along the axial direction of the lever 10 so that the inner wall surface 122 of the lock portion 12 slides along the outer wall surface 113 of the holding portion 11. (See FIG. 1A). In the present embodiment, the height of the lock portion 12 is set to be substantially the same as the height of the outer wall of the holding portion 11, but from the vicinity of the upper portion of the mounting portion 134 of the pedestal 14 in the tap body 13. As long as the height falls within the range up to an arbitrary position on the outer wall surface 113 of the outer wall 113. That is, when the lock portion 12 moves to the tap body 13 side (downward) indicated by the arrow D, the inner wall surface 122 of the lock portion 12 is at least part of the outer wall surface 145 of the base 14 and the outer wall surface 113 of the holding portion 11. What is necessary is just to set the height of the lock | rock part 12 so that it may contact | connect. The shape of the lock portion 12 is not limited to a cylindrical shape. For example, a polygonal cylindrical shape in which the cross-sectional outer shape is a square or a hexagon, or an elliptical shape even if the cross-sectional outer shape is not a perfect circle. A cylindrical shape without any corners may be used, but a shape considering the shape of the holding portion 11 can be appropriately set so that the lock portion 12 can be slidably fitted to the holding portion 11.

  In the present embodiment, the inner wall surface 122 of the lock part 12 is provided with a convex part 121 projecting in the radial direction, and the convex part 121 is disposed in the vicinity of the end of the lock part 12 on the tap body 13 side ( (See FIG. 2C). As the size of the convex portion 121, a size corresponding to the concave portion 141 of the pedestal 14 and fitting into the concave portion 141 can be appropriately set. That is, as described above, when the concave portion 141 is formed wide, the convex portion 121 having a wide lateral width may be formed on the inner wall surface 122 of the lock portion 12 correspondingly. .

  Further, in the present embodiment, as shown in FIGS. 1B and 1C, the lock portion 12 is moved upward as indicated by the arrow U, and the other end T is before and after indicated by the arrow FR. When the lever 10 is operated so as to rotate, the inner wall surface 122 of the lock portion 12 contacts the outer wall surface 145 of the pedestal 14 by placing the convex portion 121 on the mounting surface 142 of the pedestal 14. The lock part 12 can be held at such a position that it does not. Further, when the lock portion 12 is moved upward as indicated by the arrow U, the lock portion 12 is raised too much with respect to the holding portion 11 because the convex portion 121 is locked to the inclined surface 112 of the holding portion 11. Thus, it can be prevented from falling off the holding part 11.

  In the tap lock mechanism 5 according to the first embodiment as described above, when beer is discharged from the discharge port 131 of the tap 1, the lock unit 12 may be moved upward along the axial direction of the lever 10. . As a result, the inner wall surface 122 of the lock portion 12 is not in contact with the outer wall surface 145 of the base 14. That is, the lock unit 12 is brought into contact with the holding unit 11 to the extent that the lock unit 12 can be operated, and the lock unit 12 is brought into contact with the base 14 to the extent that the lock unit 12 can be operated, or the lock unit 12 and the base 14 are separated from each other. The lever 10 can be operated when the inclined surface 111 of the holding portion 11 and the inclined surface 144 of the pedestal 14 are slidable. Therefore, the lever 10 can be operated to be tilted forward indicated by the arrow F, and beer can be discharged from the discharge port 131 (see FIG. 1B). In addition, when it is desired to pour out the foam from the foam spout 132, the lever 10 (the other end T) may be operated so as to be tilted backward as indicated by the arrow R in the unlocked state (FIG. 1 ( C)).

  On the other hand, when the lever 10 is fixed to be inoperable, the lock portion 12 is moved downward as indicated by the arrow D while the lever 10 is suspended from the tap body 13, and the convex portion 121 is moved to the concave portion 141. It only has to be fitted. As a result, when the inner wall surface 122 of the lock portion 12 and the outer wall surface 145 of the pedestal 14 come into contact with each other, and the inner wall surface 122 of the lock portion 12 and a part of the outer wall surface 113 of the holding portion 11 come into contact with each other, Since the inclined surface 111 and the inclined surface 144 of the pedestal 14 cannot slide, the lever 10 cannot be moved even if the lever 10 is tilted in the front-rear direction indicated by the arrow FR. That is, since the lock portion 12 and the pedestal 14 are brought into contact with each other while the lock portion 12 is in contact with the holding portion 11 (fixed state), the lever 10 can be fixed inoperable (FIG. 1 ( A)). In the present invention, the convex portion 121 provided in the lock portion 12 and the concave portion 141 provided in the base 14 may be omitted. That is, when the lock portion 12 is lowered in the direction indicated by the arrow D, the inner wall surface 122 of the lock portion 12 and the outer wall surface 145 of the pedestal 14 and a part of the outer wall surface 113 of the holding portion 11 are in contact with each other. It may be.

  Note that it is not necessary for all the inner wall surface 122 of the lock portion 12 to contact the outer wall surface 145 of the pedestal 14, and the lever 10 is sandwiched in the operation direction of the lever 10 (the front-rear direction indicated by the arrow FR in this embodiment). Two points on the lock portion 12 that form a line segment that is substantially parallel to a line segment that connects the two front and rear points, in the present embodiment, two points facing the inner wall surface 122 of the lock portion 12 are the outer wall surface 145 of the pedestal 14. It only has to be touched.

  In the present embodiment, for example, when the tap 1 is not used, the operation unit 10 a and the shaft unit 10 b of the lever 10 are added to the lock unit 12, the holding unit 11, and the base 14 that constitute the tap lock mechanism 5. Can be disassembled. Thereby, the liquid that has landed on the flow path or the like inside the tap 1 can be easily washed. In the present embodiment, the lock portion 12 is attached to the lever 10 so that the lock portion 12 is held by the lever 10 (shaft portion 10b) via the holding portion 11 and is not easily detached from the lever 10. Yes. Thereby, the operation for fixing the lever 10 is easy, and the parts are not lost. Further, the tap lock mechanism 5 in the present embodiment can prevent liquid leakage with a simple structure in which the lock portion 12, the holding portion 11, and the pedestal 14 are provided around the shaft portion 10b of the lever 10. Since it can be applied not only to the tap attached to the front face of the beer server, but also to the stand-type tap described above, the versatility is high.

  As shown in FIG. 2G, the pedestal 14 may have a structure in which a protrusion 142a and a protrusion 142b (regulator) are formed in parallel at an arbitrary position on the mounting surface 142. The width between the two protrusions is set to a length within which the lateral width of the convex portion 121 of the lock portion 12 is accommodated. As a result, when the lever 10 is operated, the lock portion 12 is moved upward as indicated by the arrow U, and the lock portion 12 is rotated until the convex portion 121 reaches the formation position of both protrusions. When the portion 121 is placed, the convex portion 121 is accommodated between the projection 142a and the projection 142b, so that even if the lock portion 12 is swung for some reason, the convex portion 121 is placed. The rotational movement of the lock portion 12 can be restricted so that the recess portion 141 does not easily fit into the concave portion 141. Note that the formation positions of the protrusions 142a and 142b are not limited to the above-described form in which the protrusions 142a and 142b are formed in parallel. For example, as illustrated in FIG. In view, a mode in which the protrusion 142c and the protrusion 142d are formed on the mounting surface 142 so as to sandwich the recess 141 therebetween may be appropriately set. Further, the projections are not limited to the projections 142a and 142b, and the projections 142c and 142d, but the recess 121 has a width and depth that the projection 121 falls slightly downward with respect to the placement surface 142 (regulation portion). ) May be formed on the mounting surface 142.

[Second Embodiment]
A tap lock mechanism 5 according to a second embodiment of the present invention will be described with reference to the drawings. FIG. 3 is a schematic view of the tap 1 to which the tap lock mechanism 5 according to the second embodiment of the present invention is applied. FIG. 4 is an enlarged view of the components constituting the tap lock mechanism 5 shown in FIG. It is the top view and top view which show. In addition, the same code | symbol shall be attached | subjected to the component similar to the component with which the tap 1 in 1st Embodiment is provided, and the detailed description shall be abbreviate | omitted.

  The tap lock mechanism 5 in the second embodiment is different from the tap lock mechanism 5 in the first embodiment in the configuration of the lock unit 12, the holding unit 11, and the base 14. Therefore, regarding the lock part 12, the holding part 11, and the pedestal 14 constituting the tap lock mechanism 5 in the second embodiment, portions different from the tap lock mechanism 5 in the first embodiment will be described.

  As shown in FIGS. 4 (E) and 4 (F), the pedestal 14 in the second embodiment has a disk shape like the first embodiment, and has an opening (through hole) 143 in the center. It consists of a disk-shaped part 14D and a convex part 14P. Moreover, the base 14 in 2nd Embodiment has the mounting surface 142 and the inclined surface 144 similarly to 1st Embodiment. On the other hand, the pedestal 14 in the second embodiment is different from the pedestal 14 in the first embodiment in that its diameter is substantially the same as the outer diameter of the lock portion 12. Unlike the base 14 of the first embodiment, the base 14 in the second embodiment has a tapered inclined surface extending from the bottom side to the end surface of the outer wall. Is not limited to the above shape, and various shapes can be set as appropriate.

  As shown in FIGS. 4C and 4D, the holding portion 11 in the second embodiment has a cylindrical shape as in the first embodiment. Further, the holding portion 11 in the second embodiment differs from the first embodiment in that the holding portion 11 has an insertion hole 110 and has a concave groove 114 that is recessed from the outer wall surface 113 in the radial direction, as in the first embodiment. ing. The concave groove 114 is formed for loosely fitting a convex portion 122 of the lock portion 12 described later.

  FIG. 4G is a partial enlarged view in which the portion indicated by the arrow L of the holding portion 11 shown in FIG. 4C is enlarged. As shown in FIGS. 4C and 4G, the concave groove 114 includes a first guide groove 114a formed on the outer wall surface 113 of the holding portion 11 in a slanting straight line shape, and a first guide groove 114a. Continuing from the right end RS (one end), the second guide groove 114b that guides the convex portion 121 to the other end T side of the lever 10 in the unlocked state, and the right end RS (one end) of the first guide groove 114a. , And a locking groove 114c that locks the convex 121 in the unlocked state.

  4C, the first guide groove 114a is formed so as to be disposed below the outer wall surface 113 of the holding portion 11, and the left end LS (other end portion) is at the right end RS (one end portion). On the other hand, it is formed so as to be located in the vicinity of the base 14. In the present embodiment, the length X of the first guide groove 114a is set such that the lock portion 12 can be rotated by 90 ° around the holding portion 11 as will be described later. Instead, the length X corresponding to the rotation angle for rotating the lock portion 12 may be set as appropriate. In addition, the height h1 between the left end LS and the right end RS of the first guide groove 114a is set as appropriate depending on how far the lock portion 12 is moved up and down relative to the holding portion 11. (See FIG. 4G). The shape of the first guide groove 114a is not limited to the oblique linear shape as described above. For example, the first guide groove 114a extends in the horizontal direction from the right end RS to above the left end LS and hangs down from there to the left end LS. Such an inverted L shape or the like can be appropriately set. That is, as the shape of the first guide groove 114a, when the lock portion 12 is moved downward, the position of the right end RS is positioned higher than the position of the left end LS by a height h1 so that the movement distance can be secured. As long as the shape of the groove portion connecting the right end RS and the left end LS, various shapes can be appropriately set (see FIG. 4G).

  As shown in FIGS. 4A and 4B, the lock portion 12 in the second embodiment is cylindrical as in the first embodiment, and the upper surface of the outer wall 120 is above the lock portion 12. A tapered inclined surface 123 which is continuous from the upper side and is inclined toward the upper opening end is formed. Furthermore, the lock portion 12 in the second embodiment has a convex portion 121 that protrudes in the radial direction from the inner wall surface 122 as in the first embodiment, but the convex portion 121 in the second embodiment is It differs from the first embodiment in that it is provided at a substantially intermediate position in the axial direction.

  The convex part 121 is loosely fitted in the concave groove 114 of the holding part 11. With respect to the size and shape of the convex portion 121 (the concave groove 114), the convex portion 121 is loosely fitted into the concave groove 114, and the lock portion 12 is moved so that the convex portion 121 is guided along the concave groove 114. Various sizes and shapes can be appropriately set so that the lock portion 12 can slide up and down and left and right with respect to the holding portion 11 (lever 10).

  Moreover, although the convex part 121 in this embodiment is provided in the substantially intermediate | middle position in the axial direction of the lock part 12 as mentioned above, it is not limited to this, The lock part 12 is made relative to the holding part 11. The formation position can be set as appropriate depending on the distance range within the range.

  In the tap lock mechanism 5 according to the second embodiment as described above, when beer is discharged from the discharge port 131 of the tap 1, the lock unit 12 may be rotated by holding the outer wall 120 of the lock unit 12. . Thereby, the convex part 121 of the lock part 12 moves from the left end LS to the right end RS along the first guide groove 114 a of the holding part 11, and the lock part 12 moves upward along the axial direction of the lever 10. As a result, the lock unit 12 is brought into contact with the holding unit 11 to the extent that the lock unit 12 can be operated, and the lock unit 12 is separated from the pedestal 14 (fixed release state), whereby the inclined surface 111 of the holding unit 11 and the pedestal Since the 14 inclined surfaces 144 can slide, the lever 10 can be operated. Therefore, the lever 10 can be operated so as to be tilted forward indicated by the arrow F, and beer can be discharged from the discharge port 131 (see FIG. 3B). When it is desired to pour out the foam from the foam spout 132, the lever 10 may be operated so as to be tilted backward as indicated by the arrow R in the fixed release state (see FIG. 3C).

Accordingly, when the bottom surface of the lock unit 12 contacts the mounting surface 142 of the pedestal 14 while the inner wall surface 122 of the lock unit 12 is in contact with the outer wall surface 113 of the holding unit 11, the inclined surface 111 and the pedestal 14 of the holding unit 11 are contacted. Therefore, even if the lever 10 is tilted in the front-rear direction indicated by the arrow FR, the lever 10 cannot be moved. That is, since the lock portion 12 and the pedestal 14 are brought into contact with each other while the lock portion 12 is in contact with the holding portion 11 (fixed state), the lever 10 can be fixed so as not to operate (FIG. 3 ( A)). Note that the shape of the bottom surface side of the lock portion 12 is not limited to a shape in which all the surfaces are in contact with the placement surface 142, but two points before and after the lever 10 is sandwiched in the operation direction (front-rear direction) of the lever 10. The two points on the lock portion 12 that form a line segment that is substantially parallel to the line segment that connects the two, that is, the two points facing each other on the bottom surface side of the lock portion 12 in this embodiment are in contact with the mounting surface 142 of the base 14. That's fine. Therefore, the shape of the lock portion 12 may be any shape that ensures that point, and various shapes can be appropriately set.

  As shown in FIGS. 4C and 4D, the second guide groove 114b is formed so as to be continuous from the right end RS of the first guide groove 114a to the upper surface of the holding portion 11. The lock part 12 can be removed from the holding part 11 by moving the convex part 121 upward along the second guide groove 114b. On the other hand, as a tap lock mechanism in the present invention, as long as the lock portion 12 can be loosely fitted to the holding portion 11 so that the convex portion 121 can move along the first guide groove 114a, the second guide is provided. The groove 114b may not be provided. In the present embodiment, the second guide groove 114b has a linear shape substantially parallel to the axial direction of the holding portion 11, but is not limited thereto, and guides the lock portion 12 to the other end T side of the lever 10. For example, the shape may be an oblique straight line that is substantially non-parallel to the axial direction of the holding portion 11 or a curved shape.

  As shown in FIGS. 4C and 4G, the holding portion 11 has a locking groove 114c formed downward from the right end RS of the first guide groove 114a. Thereby, the convex part 121 moved to the right end RS along the first guide groove 114a can be locked to the locking concave groove 114c, and the lock part 12 is temporarily moved on the outer wall surface 113 of the holding part 11. Can be retained. The distance between the right end RS and the lowest point M of the locking groove 114c is determined by moving the protrusion 121 to the second guide groove 114b when the lock portion 12 is rotated and the lever 10 is fixed. A distance h2 at which the convex portion 121 can be easily slid from the locking concave groove 114c toward the first guide groove 114a by the rotational stress of the lock portion 12 without moving the lock portion 12 upward. Can be set as appropriate. The distance h3 between the lowest point M and the left end LS can be set as appropriate so that the position of the lowest point M is higher than the position of the left end LS.

B) is a diagram showing a tap lock mechanism in a fixed state. For example, like a knock-type ballpoint pen, the top surface 12t of the cylindrical lock portion 12 provided around the shaft portion 10b of the lever 10 is knocked, and the lock portion 12 is pushed downward as indicated by the arrow D, thereby The gap 146 is filled (fixed state) by inserting the lower end of the lock portion 12 into the gap 146 formed between the outer peripheral end of the fourteen opening portions 143 and the outer periphery of the shaft portion 10b. As a result, the lever 10 can be fixed so as not to operate (see FIG. 8). In addition, although the cylindrical operation part 10a is provided so that it may be provided around the axial part 10b, the said operation part 10a is provided from the viewpoint of the operativity of the lever 10, and the designability, Due to the configuration, the operation unit 10a may be omitted.

  The tap lock mechanism 5 in the present embodiment described above is applied to the tap 1 in a form in which the lever 10 is suspended from the upper surface of the tap body 13, but is not limited thereto, and the tap lock mechanism in the present invention. 5 can be applied to, for example, the tap 1 in a form in which the lever 10 is attached in parallel (horizontal) to the tap body 13. In addition, the tap lock mechanism according to the present invention may be applied to, for example, the tap 1 in which the lever 10 is attached so as to be suspended from the side surface of the tap body 13 when the tap 1 is viewed from the front. it can.

  In addition, the tap 1 to which the tap lock mechanism 5 in the present embodiment is applied is not limited to a box-shaped housing such as a beer server, and may be attached to a portable container such as a plastic bottle. Thereby, the beer filled in the container can be directly poured out. When the tap 1 is attached to such a portable container, the frequency of contact with the lever 10 is expected to increase. Therefore, the tap lock mechanism in this embodiment is particularly useful.

  The tap lock mechanism of the present invention is useful for fixing an inoperable lever of a tap (cock) for discharging beer or the like provided at a restaurant such as a beer hall from a beer server (dispenser). Can be used in the service industry in general. Moreover, it can utilize also in the lock mechanism which fixes the cock which discharges a desired liquid from the container used not only in the service industry which carries out the service which provides beer etc. but in other industries.
