A T-shaped plate-like member, and a movable member 4 movably attached between the upper locking piece 11 and the lower locking piece 31, and movable by moving the movable member 4 in the left-right direction. A first position where the protrusion 42 of the member 4 abuts against the upper surface of the lower locking piece 31 and restricts the upward bending of the lower locking piece 31, and the contact between the protrusion 42 of the movable member 4 and the lower locking piece 31. The second position is taken out of contact.

  The latching tool 10 includes a metal hanging part main body 1 with an upper locking piece 11 integrally formed, a fixed side mounting member 3 made of hard resin, and a movable member 4 made of hard resin. The movable member 4 is previously assembled in the fixed side mounting member 3 to form a primary assembly 7, and the primary assembly 7 is screwed to the back surface of the metal hook body 1.

  The metal hanging portion main body 1 made of stainless steel or the like includes a rear long plate-like member 114, a right short plate-like member 112, a front long plate-like member 111, and a left short plate-like member 113. The frame structure is formed to have a square shape in plan view and has a hollow 115 penetrating in the vertical direction. In addition, the left and right corners in front of the hanging portion main body 1 are rounded so as not to hurt the hand. The hanging portion main body 1 hangs a towel on the front long plate-like member 111, and the rear long plate-like member 114 is formed with an upper locking piece 11 and a member to which the primary assembly 7 is screwed. Become. Although this invention is provided with the metal hanging part main body 1 with comparatively heavy weight, it shows the outstanding installation stability.

  The upper locking pieces 11 are respectively formed so as to protrude rearward from the upper side on both sides of the hanging portion main body 1 in the left-right direction. Since the upper locking pieces 11 on both sides have the same shape, only one upper locking piece 11 will be described. The upper locking piece 11 is formed by chamfering the upper corner of the rectangular parallelepiped member having a predetermined height and a predetermined width on the front side (the side of the hanging body 1). By forming the inclined surface 119 cut out in a chamfered shape, the front hanging plate 24 of the rail portion 2 does not become an obstacle to the locking when the upper locking piece 11 is engaged with the rail portion 2 (FIG. 16). reference). Further, the top surface 113 of the upper locking piece 11 contacts the upper plate inner surface 211 of the rail portion 2. Further, the primary assembly 7 can be installed on the right-angled inner corner portion 50 formed by the back surface of the rear long plate-like member 114 and the lower surface of the upper locking piece 11. Further, by providing the upper locking pieces 11 on both sides, the hanging portion main body 1 having a long metal frame structure can be stably installed on the rail portion 2 (see FIGS. 1 and 3).

  Two screw holes for installing the primary assembly 7 are formed on the lower surface of the upper locking piece 11, and the rear surface of the long member 114 at the rear of the right-angled inner corner portion 50 stands rearward. A rod-shaped protrusion 12 and a hook portion 13 having a pair of left and right ends extending downward are provided at positions slightly below the rod-shaped protrusion 12. The distal end portion of the rod-shaped protrusion 12 extends into the horizontally elongated recess 44 of the movable member 4, and the movement of the movable member 4 in the left-right direction is restricted by hitting the longitudinal end of the inner wall of the horizontally elongated recess 44. The hook portion 13 is locked in the locking hole 37 of the fixed-side mounting member 3 and fixes the fixed-side mounting member 3 in cooperation with screwing. In this way, the primary assembly 7 is strongly fixed to the hanging portion main body 1 with the screw a and the hook portion 13.

  An elliptical and thin friction material 9 is attached to the top surface 113 of the upper locking piece 11. Thereby, the top surface 113 of the upper latching piece 11 and the upper board inner surface 211 of the rail part 2 can contact | abut strongly (refer FIG.1 and FIG.16). The material of the friction material 9 is not particularly limited as long as it can provide a friction higher than the contact friction between metal and metal.

  The resin fixed-side mounting member 3 includes a plate-like base portion 32 serving as a top plate, a plate-like front member 33 extending downward from the front end of the base portion 32, and extending downward from substantially the center in the front-rear direction of the base portion 32. A plate-like intermediate member 34 having a height of about 1/2 of the height of the front member 33 and a lower locking piece 31 extending rearward from the lower end central portion of the front member 33 are provided. That is, the lower locking piece 31 is formed on the fixed-side mounting member 3 that is a separate member from the hook body 1. The plate-like base portion 32 is cut out at the front side and the center portion in the left-right direction, and the front member 33 is cut out at the center portion in the left-right direction. As a result, weight saving and material saving are achieved. The intermediate member 34 includes a plate-like main body 341 and a locking piece 342 that bends forward from the tip of the plate-like main body 341. The intermediate member 34 is located at the center in the left-right direction of the front member 33 and has a length of about 1/3 of the length of the front member 33 in the left-right direction.

  Note that the fixed-side mounting member 3 is not limited to the above shape, and various modifications can be made. For example, the plate-like base 32 and the front member 33 may be cut out. Further, the locking piece 342 of the intermediate member 34 may be omitted. In this case, the U-shaped groove 45 of the movable member 4 can also be omitted.

  The base portion 32 is screwed to the back surface of the upper locking piece 11 and includes a pair of screw holes 35. Further, a through hole 36 through which the rod-shaped member 12 passes is formed above the front member 33 and in the center in the left-right direction, and a pair of locking holes 37 for locking the hook portion 13 are formed on both sides below. Yes. The front member 33 below the pair of locking holes 37 is notched and thin, and has a step here. As a result, since the tip of the hook portion 13 is locked to the thin portion below the locking hole 37, the hook portion 13 does not protrude rearward from the surface of the front member 33, and obstruction of the formation of the rectangular space 39. Never become.

  The lower locking piece 31 has a flat upper surface and a slightly projecting lower surface below. Moreover, the connection part (neck part) with the lower end of the front member 33 of the lower latching piece 31 is thin. By making the upper surface flat, a space 39 having a rectangular cross section can be formed, and by making the lower surface slightly projecting downward, the lower locking piece 31 can be easily fitted to the rail portion 2 and connected. By making the part (neck part) thin, it can be bent inward (upper side) if it is strongly pressed with a finger, and the lower locking piece 31 can be more easily fitted to the rail part 2.

  The plate-shaped intermediate member 34 is formed to create a space 39 in which the movable member 4 is fitted and to guide the movement of the movable member 4 in the left-right direction. That is, the two vertical wall portions of the front member 33 and the intermediate member 34 and the lower locking piece 31 can create a space portion 39 having a substantially rectangular cross section in which the movable member 4 is movably fitted in the left-right direction. Further, the movable member 4 is locked by the locking piece 342 of the intermediate member 34, so that the movable member 4 does not easily fall off the space portion 39, and on the other hand, it moves smoothly when moved in the left-right direction by hand. It has become.

  The resin movable member 4 is a substantially T-shaped plate-like member having a protrusion 42 protruding downward. That is, a projection 42 having a predetermined length in the left-right direction and a height of about several millimeters is formed from the center of the lower end of the rectangular plate-shaped main body 41. The whole including the protrusion 42 and the plate-like main body 41 is plate-like. The lateral length of the protrusion 42 may be substantially the same as the lateral length of the lower locking piece 31. Further, the height from the lower end of the protrusion 42 to the upper end of the plate-like main body 41 may be the same as the height of the space portion 9 of the fixed side attachment member 3.

  Further, a laterally long recess 44 with a central upper portion cut out is formed on the front surface of the plate-like main body 41 of the movable member 4. The notch 442 at the upper center is for making it easier for the rod-shaped protrusion 12 to fit into the horizontal U-shaped groove 45 when the primary assembly 7 is attached to the back surface of the metal hook body 1. The horizontally elongated recess 44 has a function of restricting the range of movement of the movable member 4 in the left-right direction by entering the distal end side of the rod-shaped member 12 of the hanging portion main body 1. Further, a lateral U-shaped groove 45 extending in the left-right direction is formed on the rear surface of the plate-like main body 41 of the movable member 4. The horizontal U-shaped groove 45 has a function of guiding the movement of the movable member 4 in the left-right direction by the engagement of the locking piece 342 of the intermediate member 34 of the fixed side mounting member 3.

  If such a movable member 4 is incorporated in the space portion 9 of the fixed-side mounting member 3 and is centered so as to be bilaterally symmetric, the protrusion 42 and the lower locking piece 31 are in contact with each other (first position). Therefore, even if the lower locking piece 31 is pressed with a strong force from below, it does not bend. Thereby, it is the situation fixed to the rail part 2 in use condition, and the fixation to the rail part 2 is stabilized.

  Further, when the movable member 4 is moved leftward or rightward from the state in which the movable member 4 is incorporated in the space 9 of the fixed side attachment member 3 so as to be bilaterally symmetric, the protrusion 42 and the lower locking piece 31 are moved. Is released (second position), and when the lower locking piece 31 is manually pressed from below, it will bend inward. This state is a situation in which the latching tool is removed from the rail portion 2 in the use state, and the lower locking piece 31 can be bent inward when being removed from the rail portion 2, thereby facilitating the removal.

  A locking groove 43 (first locking portion) extending in the front-rear direction is formed at the center in the left-right direction of the protrusion 42 of the movable member 4, and the center in the left-right direction on the upper surface of the lower locking piece of the fixed side mounting member 3. A protrusion 311 (second locking portion) extending in the front-rear direction is formed on the. As a result, at the first position, if the protrusion 42 of the movable member 4 and the lower locking piece 31 are in contact with each other and the first locking portion and the second locking portion are locked, unless a strong external force is applied. The movable member 4 and the lower locking piece 31 do not come off. In addition, when the movable member 4 is moved in the left-right direction by hand, the first locking portion and the second locking portion can be sensed and the contact between the protrusion 42 of the movable member 4 and the lower locking piece 31 can be experienced. You can prevent mistakes.

  The latching tool 10 previously forms the primary assembly 7 by assembling the movable member 4 in the space 39 of the fixed side attachment member 3, and the primary assembly 7 is formed on the back surface of the metal hook body 1 with a rod-like projection. 12 is installed in the horizontally long recess 44 of the fixed side mounting member 3 and the hook portion 13 is fitted in the locking hole 37, and then screwed by the screw a. Thereby, the primary assembly 7 is firmly fixed to the hanging part main body 1.

  The rail portion 2 to which the latching tool 10 is fitted has an elongated shape, and includes an upper plate 21 extending forward from the upper end of the vertical plate, a lower plate 22 extending forward and below from the upper plate of the vertical plate, It has an opening formed by the plate 21 and the lower plate 22. Note that the front end portion of the lower plate 22 has a slightly projecting cross-sectional shape on the upper side, and can be strongly locked with the lower locking piece 31 of the hooking tool 10. Moreover, the upper plate 21 forms a plate-like portion having a low height that hangs downward from the front end. Thereby, installation to the rail part 2 of the latching tool 10 is stabilized.

  A method of attaching the assembled latch 10 to the rail portion 2 will be described below. In the hook 10, the height from the upper surface of the upper locking piece 11 to the lower surface of the lower locking piece 31 is the same as the dimension from the upper plate inner surface 211 to the lower plate inner surface 221 of the rail portion 2.

  The latching tool 10 cancels | releases contact | abutting with the protrusion 42 of the movable member 4, and the lower latching piece 31 of the stationary-side attachment member 3 previously, and makes it the 2nd position. That is, the state seen from the front is the state shown in FIG. 11 on the left side, and the state seen from the front is the state shown in FIG. 12 on the right side, that is, the movable member 4 protrudes outward. Next, the upper locking piece 11 is made to sneak into the inner surface of the rail portion 2 in such a posture that the latching tool 10 is inclined downward toward the rear. At that time, the protrusion 222 at the tip of the lower plate 22 of the rail portion 2 and the tip of the lower locking piece 31 are in contact with each other (FIG. 15). From this state, when the latching tool 10 is pushed in so as to be submerged in the rail part 2, the lower locking piece 31 bends inward (upward), so that the latching tool 10 enters the rail part 2, and then the lower latching part. Since the stop piece 31 is restored to its original shape, the hook 10 is strongly fixed to the rail portion 2.

  Next, the latching tool 10 is determined without fine adjustment or fine adjustment of the horizontal position of the rail portion 2 by sliding. Next, the movable member 4 is slid inward, and the protrusion 42 of the movable member 4 and the lower locking piece 31 of the fixed side attachment member 3 are brought into contact with each other to be in the first position. In this contact state, the engagement between the engagement groove 43 of the projection 42 of the movable member 4 and the projection 311 of the lower engagement piece 31 of the fixed side attachment member 3 can be experienced and can be performed reliably. Even if it is going to remove the latching tool 10 from the rail part 2 in the 1st position, since the lower latching piece 31 cannot bend inward by presence of the movable member 4, it becomes impossible. That is, the fixing of the latching tool 10 to the rail portion 2 is stable.

  Next, in order to remove the latching tool 10 from the rail portion 2, a hand is put in from the opening in front of the rail portion 2, and the movable member 4 is pushed further inward or pulled out, and the protrusion 42 of the movable member 4 is formed. The locking groove 43 and the locking of the protrusion 311 of the lower locking piece 31 of the fixed attachment member 3 are released, that is, the protrusion 42 of the movable member 4 and the lower locking piece 31 of the fixed mounting member 3 are brought into contact with each other. Release to the second position. Next, the hooking tool 10 may be pulled down from the rail portion 2 while bending the lower locking piece 31 in such a posture that it is inclined downward toward the rear.

  The latch of this invention is not limited to the said form, A various modification can be taken. For example, all the upper and lower members of the hook 10 can be reversed. That is, the hooks shown in FIGS. 1 and 2 are turned upside down and attached to the rail portion 2. In this case, the rail portion 2 is also turned upside down. Specifically, the lower locking piece is made of metal that contacts the lower plate inner surface of the rail portion and is integrally formed with the hanging portion main body, and the upper locking piece is pressed against the upper plate inner surface of the rail portion. The movable member is a substantially inverted T-shaped plate member having a protrusion protruding upward, and is movable in the left-right direction between the upper locking piece and the lower locking piece. It can be attached to.

  In the description of the lower locking piece and the upper locking piece in the latching device 10 of such a modified example, “upper” in the description of the upper locking piece and the lower locking piece in the above-described locking device 10 is “lower”. And “lower” as “upper” respectively. In addition, the description of the hanging portion main body and the movable member in the latching device 10 according to the modified example is made by referring to the words “upper” and “lower” in the description of the hanging portion main body and the movable member in the above-described latching device 10. Is the same as replacing “upper” respectively.

  Moreover, in the latch of this invention, an upper latching piece is not limited to what was previously integrally formed with the hook part main body, and may be formed in the primary assembly body. In this case, it is preferable that the upper locking piece is made of hard resin, and that the upper locking piece is formed with a screw hole connected to the hook body. Even if the upper locking piece is made of a hard resin, it does not bend by the action of an external force as long as the member has a thickness.

  The present invention is non-slidably attached to the rail provided on the front of a kitchen stand, etc., and is easy to use, such as a suspended towel, and can be easily attached to and removed from the rail. As a result, the functionality of the kitchen table is increased and attractive products can be provided.
