"Specific configuration of push-pull lock that switches from specification to single-sided specification (pull specification or push specification)" is disclosed.

  In these inventions, for example, when an operation handle of an indoor door such as a toilet or a bedroom is pushed to open the door by vigorously pushing to the indoor side (the other side), the door of the doorway is operated to the indoor operation handle. This is useful when the door closer is not attached to the joinery in the case where the door is opened by operating to the outside.

The reason is that when switching from push-pull specification to single-sided specification (for example, pull specification), when opening the door, it is necessary to open the door by pulling it to the near side. This is because it is possible to prevent as much as possible the situation in which the doors are opened vigorously.

Reference numeral 17A denotes an engagement rod fixed to the handle mounting shaft portion 32A (corresponding to the conventional fitting rod 17). One or a plurality of engagement portions 17a are provided radially outward on the outer periphery of the engagement rod 17A. It protrudes. In the present embodiment, the engaging portion 17a is a single small protrusion.

(4) Movable body 41
The movable body 41 is an annular plate in this embodiment. The plate thickness, shape, size and the like of the movable body 41 can be arbitrarily designed. For example, the movable body 41 may be C-shaped, horseshoe-shaped, or both arms or one-armed. If the movable body 41 has a function of switching to a single-sided specification mode, design changes such as plate thickness, shape, size, etc. are slight differences that do not affect the effects of the invention.

  Reference numeral 42 denotes an annular sliding contact portion, and the sliding contact portion 42 is interposed, for example, between the outer wall surface of the support seat 41A and the inner wall surface of the cover 14A. Since the sliding contact portion 42 of the embodiment has a plate-like donut shape, it has an outer periphery 42a and an inner periphery 42b.

  Thus, in the present embodiment, a protruding outer end portion 43 located in the opening 53 formed in the circumferential direction of the cover 14A is formed on the outer periphery 42a. The outer end portion 43 slightly protrudes from the opening 53 and has, for example, a function as a knob. Here, “position in the opening 53” means that the outer end portion 43 is located within a range that can be operated from the outside. Accordingly, not only the case where the outer end portion 43 protrudes from the opening but also the case where the outer end portion 43 faces the opening is included.

  On the other hand, an escape notch portion 45 of the movable body is formed in a radially outward direction at an appropriate location on the inner periphery 42b that forms the loose fitting hole 44 for the handle. This cutout portion 45 is a small cutout in this embodiment. In addition, although it is a detailed matter, in the present Example, the mark M for confirming a specification aspect is attached | subjected to the one side upper surface of the sliding contact part 42.

The shape of the opening 53 is not particularly limited as long as the movable body 41 can exert a switching function. Reference numeral 54 denotes a viewing window formed at an appropriate position of the cover portion 51.

(6) Switching to single-sided specification mode FIGS. 7 and 8 are conceptual explanatory diagrams when switching from the original push-pull specification (FIG. 7) to the single-sided specification mode (FIG. 8), as described above. It is.

  As is apparent from FIG. 7, in the case of the original push-pull specification, the relief cutout portion 45 of the movable body 41 can receive or escape the engagement portion 17a of the mounting shaft portion 32A of the handle 10A. Therefore, the handle 10A can be operated (push-pull) inward and outward as indicated by an arrow.

  On the other hand, when switching the specification mode, if the outer end portion 43 of the movable body 41 is operated with a finger, for example, the movable body 41 is rotated, and the notch portion 45 for the movable body is displaced, Since the obstacle portion (in the embodiment, the edge portion of the inner periphery 42b) 46 is positioned so as to overlap (close) the engagement portion 17a of the mounting shaft portion of the handle as shown in FIG. Is switched to a specific specification mode (in the embodiment, a specification).

  In the present embodiment, the movable body 41 is interposed between the support seat 4A and the cover 14A of at least one handle (for example, the inner handle) 32A. However, this is an embodiment and the present invention is not limited to this. It is not something.

  Further, according to the present invention, when the movable body 41 is switched, the obstacle portion 46 only has to be an obstacle (obstacle) to the engaging portion 17a of the handle 10A. The sliding contact portion 42 connected to the outer end portion (operation portion) 43 may be located in the annular portion 23 of the support seat 4A, or the back side surface (the inner wall surface of the door) of the support seat 4A. Side).

  Furthermore, the configuration of the present invention may be limited to a click mechanism (for example, a click ball, a click spring, an engagement configuration such as a convex portion and a concave portion) for stopping at a predetermined position when the movable body is operated.

  Hereinafter, in this section, the second to fourth embodiments of the present invention will be described. Since the second embodiment is a design change example of the movable body, only the main constituent members are shown, and the main constituent members are denoted by the same reference numerals as those of the second embodiment. In the third embodiment, there is no movable body corresponding to the operation piece, and the cover 14B itself has a function corresponding to the movable body 41. Therefore, the same drawing as FIG. 4 (FIG. 11). The details of the third embodiment are omitted. Further, since the fourth embodiment is a replaceable modification of the third embodiment, it will be described briefly.

  9 and 10 are conceptual illustrations. The movable body 41A is formed in a short long plate shape or an eaves shape, for example, like an ordinary switch piece, and is supported on either the outer wall surface (this embodiment) of the support seat 4A or the inner wall surface of the cover 14A. It is pivotally supported via 47. Therefore, the reference numeral 43 of the long plate-like movable body 41A corresponds to the outer end portion, and the reference numeral 46A corresponds to the obstacle portion of the inner end portion.

  In the case of this embodiment, the opening 53 is appropriately formed. When the outer end portion 43 of the movable body 41A is operated from the outside configured as described above, the obstacle portion 46A is displaced, so that the same object and effect as in the first embodiment can be obtained.

  The third embodiment shown in FIGS. 11 and 12 is mainly different from the first embodiment in that the cover 14B itself has a function corresponding to the movable body 41.

  First, with reference to FIG. 12, reference numerals are given to the respective portions of the cover 14B. 51B is an annular cover portion, 52B is a center hole for a handle attachment shaft portion formed on the upper surface of the cover portion, and 45B is a handle engagement portion relief formed radially outward from the inner periphery of the center hole 52B. The notch part 46B is an obstacle part corresponding to the inner peripheral part of the cover. The obstacle portion 46B corresponds to the vicinity of the relief cutout portion 45B.

  In addition, as shown in FIG. 11, the inner wall surface of the peripheral side wall of the cover portion 51B of the cover 14B has a plurality of engagements with circumferential engagement grooves 23a formed on the outer periphery of the annular portion 23 of the support seat 4B. An engagement small protrusion 55 is provided. Therefore, in the case of this embodiment, the cover 14B can be rotated by a predetermined amount via the guide means (engagement groove 23a, engagement small protrusion 55). In other words, the cover 14B can be rotated while being rubbed (in an engaged state) by the operating force of the hand.

  In the above configuration, when the specification mode is switched, the cover 14B is turned by a predetermined amount by hand, the cover notch portion 45B of the cover is displaced, and the obstacle portion 46B corresponding to the inner peripheral portion of the cover is attached to the handle 10B. It is positioned so as to overlap with the engaging portion 17a provided on the mounting shaft portion, and the original push-pull specification is switched to the one-sided specification mode. Even if comprised in this way, the objective and effect same as 1st Example can be achieved.

  In the third embodiment, the mode of “turning the cover by a predetermined amount by hand” is not limited to the case where the cover 14B is picked by hand as in the embodiment and rotated as it is. In the case of being fixed to the support seat 4B, the case where the attachment position of the cover 14B is appropriately changed after the fixing tool is removed is also included.

  The fourth embodiment shown in FIG. 13 is mainly different from the first embodiment in that the cover 14C itself has a function corresponding to the movable body 41, as in the third embodiment. This cover 14C has a non-circular center hole 52C for a handle formed in the center of a disk-shaped outer wall surface located on the front side rather than a belt-like outer periphery, and the non-circular shape of the center hole 52C. The obstacle portion 46C in the inner peripheral portion that forms a barrier against the engaging portion 17a of the handle 10A.

  That is, as shown in the schematic diagram on the left side of FIG. 13, the engaging portion 17a of the handle 10A is located in the center hole 52C having an inner diameter larger than the outer size of the mounting shaft portion 32A of the handle (on the engaging portion 17a). In the case where the obstacle portion 46C does not oppose), the “push” and “push” operations can be performed on the handle 10A as indicated by an arrow.

  However, when the specification mode is switched, the cover 14C is turned by a predetermined amount by hand, and the position of the non-circular center hole 52C of the cover 14C is displaced, and the obstruction that forms the non-circular shape of the center hole 52C. When the portion 46C is positioned so as to overlap the engaging portion 17a provided on the mounting shaft portion of the handle, the original push-pull specification is switched to the one-sided specification mode. In this embodiment, “push” can be performed but “pull” cannot be performed. Therefore, this embodiment is not a preferable embodiment in relation to the object of the invention.

  The present invention is mainly used in the locksmith and joinery industries.
