- the cam springs 45, 46 are in a balanced state, and therefore the cam member 43 ⁇ / b> A is located at the center in the cam holder 44.
- the rod entry portion 55 of the cam member 43 ⁇ / b> A is held at a position that matches the rod entry portion 54 of the cam holder 44 and the rod insertion groove 50 of the cam cover 41.
- FIG. 6B shows a state in which the rod 22 has moved up the ascending surface portion 56a and progressed to the flat surface portion 56b.
- the door 1 is opened for the first time.
- the rod 22 does not travel into the return passage 58 during directional movement.
- FIG. 6C shows a state where the rod 22 and the engaging portion 57 are engaged.
- the engaging portion 57 is lower than the height of the upper edge portion of the ascending surface portion 56 d constituting the entry passage 56 and lower than the height of the upper edge portion of the ascending surface portion 58 a constituting the return passage 58. Therefore, the movement of the rod 22 is restricted by the pair of upward surface portions 56d and 58a. Thereby, the movement of the rod 22 in the directions of the arrows X1 and X2 in the engaging portion 57 is restricted.
- a force in the closing direction (in the direction of arrow Y2) is applied to the rod 22.
- a protruding portion 61 is formed on the arrow Y2 direction side with respect to the engaging portion 57 of the cam member 43A. Since the protrusion 61 restricts the movement of the rod 22 in the arrow Y2 direction, the door 1 is not closed even when a force in the closing direction (arrow Y2 direction) is applied, and the open state can be maintained. (This state is hereinafter referred to as a locked state).
- the rod 22 moves to the return passage 58 by moving the door 1 in the opening direction (arrow Y1 direction) in this way. Specifically, the rod 22 goes up the ascending surface portion 58a, falls down and then falls into the recessed surface portion 58b. Thereby, the rod 22 is detached from the engaging portion 57 and the return passage side end portion 57b, and the engagement between the rod 22 and the engaging portion 57 is released.
- FIG. 6D shows a state where the rod 22 is moving in the return path 58 in the direction of the arrow Y2.
- the rod 22 is guided by the rod insertion groove 50 to perform a substantially linear operation in the directions of the arrows Y1 and Y2, whereas the cam member 43A is placed on the floor 2. It is set as the structure which latches the rod 22 by sliding to the arrow X1, X2 direction along.
- the amount of protrusion of the rod mechanism 20A in the horizontal direction relative to the door 1 can be reduced. It is possible to prevent the rod mechanism 20A from interfering when opening and closing.
- the rod locking mechanism 40A can have a flat shape because the cam member 43A moves in parallel with the floor 2. Therefore, when the floor 2 is disposed on the rod locking mechanism 40A, the protruding amount of the rod locking mechanism 40A from the floor 2 can be reduced.
- FIG. 11A, FIG. 11B, FIG. 15A to FIG. 15F, FIG. 17A, and FIG. 17B are diagrams for explaining another embodiment of the present invention.
- FIGS. 1, 2, 3A, 3B, 4, 5, and 6A to 6D used for explaining the first embodiment are shown. Constituent elements corresponding to those shown are designated by the same reference numerals and description thereof is omitted.
- the door stopper 10B according to the present embodiment also uses a cam member 43B (locking member) having a substantially heart-shaped rod passage 48B, and the rod 22 and the cam member 43B constitute a cam mechanism.
- the rod 22 locked to the engaging portion 57 is configured not to return to the entry passage 56.
- the height of the engaging portion 57 is lowered, and the step formed thereby prevents the rod 22 from returning to the entry passage 56.
- the door stop 10B according to the present embodiment is characterized in that the entrance passage 56, the engaging portion 57, and the return passage 58 formed in the cam member 43B have the same height.
- the approach passage side end portion 57a and the return passage side end portion 57b of the engagement portion 57 are asymmetrical.
- the extension amount in the arrow Y1 direction of the return passage side end 57b is set to be larger than the extension amount in the arrow Y1 direction of the entry passage side end 57a.

Therefore, the cam member 43B is positioned at the center in the cam holder 44, and the rod entry portion 55 of the cam member 43B is held at a position that matches the rod entry portion 54 of the cam holder 44 and the rod insertion groove 50 of the cam cover 41. It is in a state.
- the inclined wall 59 constituting the entry passage 56 is configured to be positioned in the rod insertion groove 50 in the free state. Therefore, when the door 1 is moved in the opening direction from the free state, the rod 22 advances through the entrance passage 56 as shown in FIG.
- the cam member 43B moves in the direction of the arrow X1 in the figure as the rod 22 advances through the entry passage 56. Therefore, the cam member 43B is loaded with an elastic force that moves and urges the cam member 46 in the direction of the arrow X2.
- the cam member 43B moves in the direction of the arrow X2 by the rod 22 getting over the entrance passage side end 57a.
- the rod 22 moves relative to the cam member 43B in the arrow X1.
- the extension amount in the arrow Y1 direction of the return passage side end portion 57b is set to be larger than the extension amount in the arrow Y1 direction of the entry passage side end portion 57a. Therefore, the rod 22 that has passed over the end portion 57a on the entrance passage abuts on the end portion 57b on the return passage side and does not immediately proceed to the return passage 58. Therefore, the rod 22 that has passed over the entry passage side end 57 a is reliably engaged with the engagement portion 57.
- FIG. 9 shows a state where the rod 22 and the engaging portion 57 are engaged.
- the door 1 is locked in the open state (locked state) by the door stop 10A.
- the position of the cam member 43B is still offset from the center in the direction of the arrow X1. That is, the cam member 43A is urged to move in the direction of the arrow X2 by the cam spring 46.
- FIG. 10 shows a state in which the rod 22 is moving in the return path 58 in the direction of the arrow Y2.
- the door stop 10B can make the entrance passage 56, the engaging portion 57, and the return passage 58 have the same height, so that it is possible to simplify the manufacture of the cam member 43B. Further, the coil spring 24 in the rod mechanism 20A can be eliminated, and the number of parts of the rod mechanism 20A can be reduced.
- FIG. 11A, FIG. 11B, and FIG. 12 are diagrams for explaining a door stop 10C according to the third embodiment.
- the door stop 10A In the door stop 10A according to the first embodiment described above, a configuration in which the rod 22 provided in the rod mechanism 20A is simply a cylindrical rod shape is shown. In contrast, the door stop 10C according to the present embodiment is characterized in that the rod is a ratchet rod 60.

- the front end of the leaf spring 62 is configured to allow only one-way rotation of the ratchet rod 60 by engaging with the teeth forming the ratchet rod 60.
- reference numeral 64 denotes an attachment hole through which a fixing screw is inserted when the rod mechanism 20B is fixed to the door 1.
- FIG. 12 shows the rod locking mechanism 40C.
- the door stop 10C according to the present embodiment also uses a cam member 43C (locking member) having a substantially heart-shaped rod passage 48C.
- a gear portion 70 constituting a rack is formed on the inner peripheral portion of the entry passage 56 and the engagement portion 57. Is formed.
- the module of the ratchet rod 60 and the module of the gear unit 70 are set equal. Further, the width of the passage between the gear portions 70 is set to be slightly larger than the rod diameter so as not to disengage. Therefore, the ratchet rod 60 and the gear portion 70 constitute a rack and pinion mechanism. Further, since the ratchet rod 60 is configured to be allowed to rotate only in one direction by the leaf spring 62 as described above, the ratchet rod 60 and the gear portion 70 also function as a ratchet mechanism.
- the ratchet rod 60 and the gear portion 70 constitute a ratchet mechanism.
- the rotation direction of the ratchet rod 60 is set to a direction that allows the ratchet rod 60 to move toward the engaging portion 57. Therefore, it is possible to prevent the ratchet rod 60 from moving in the return direction.
- the height of the rod approach part 55, the approach path 56, the engaging part 57, and the return path 58 can be made equal.
- FIG. 14A, FIG. 14B, FIG. 15A to FIG. 15C, FIG. 16D to FIG. 16F, FIG. 17A, and FIG. 17B show a door stop 10D that is the fourth embodiment.
