When adjusting the open state, push the shutter part toward the casing. Then, the advancing / retracting shaft portion connected to the shutter portion is displaced against the urging member accommodated in the casing against the urging force, and the guide protrusion on the inner periphery of the rotating member is inserted into the cam groove on the outer periphery of the advancing / retreating shaft portion. Guided and moved from the original position in the cam groove (shallow groove, middle groove or deep groove) in the axial direction to abut against the opposing oblique groove, and when the push is released, the next position (original position) To a shallow groove portion, a middle groove portion, or a deep groove portion adjacent to each other.

  Here, each position of the shallow groove portion, middle groove portion, and deep groove portion of the cam groove corresponds to the fully open position, the half open position, and the closed position of the shutter portion, so that the shutter portion is in the fully open state, the half open state, or the closed state. Can be.

  The present invention is configured as described above and has the following effects.

  Since the shutter portion can be in a fully open state, a half open state, or a closed state, it is possible to provide a push register in which the shutter can be adjusted in three stages of full open, half open, and closed.

  Embodiments of the present invention will be described below with reference to the drawings.

  The push type register according to this embodiment is attached to the end of a duct on the indoor side for ventilation. As shown in FIGS. 1 to 10, the casing 1 made of synthetic resin to be installed on the indoor side of the building, and the casing A shutter 3 capable of opening and closing one indoor opening 2, a cylindrical rotating body 4 rotatably accommodated in the casing 1, and a spring 5 in the direction of the shutter 3 in the casing 1. And an advancing / retreating shaft portion 6 (see FIG. 6) to be urged. 7 is a sponge.

  A filter material 8 is interposed between the shutter portion 3 and the casing 1 and fixed in the casing 1 by a frame body 9. The shutter part 3 is fitted and connected to the tip of an advance / retreat shaft part 6 that can advance and retreat in the axial direction. As shown in FIG. 6, the advancing / retreating shaft portion 6 is integrally formed by fitting a shutter side shaft member 10 and a casing side shaft member 11 to each other, and is housed in the rotating body 4 and has an outer periphery. Has a cam groove 12. The cam groove 12 is formed on the outer peripheral surface between the shutter side shaft member 10 and the casing side shaft member 11. The base end side of the spring 5 that urges the advancing / retreating shaft portion 6 in the direction of the shutter portion 3 is fitted into a pedestal 13 fixed to the casing 1.

  As shown in FIGS. 7 to 10, the cam groove 12 has a shallow groove portion 14, an intermediate groove portion 15 and a deep groove portion 16 in the axial direction, and opposing skew groove portions 17 to be connected to each other and guided to the next position. And have. Three sets of the shallow groove portion 14, the intermediate groove portion 15, the deep groove portion 16 and the like are provided on the outer periphery of the advance / retreat shaft portion 6. On the other hand, three guide projections 18 guided along the cam groove 12 are formed on the inner periphery of the rotating body 4 at intervals of 120 °.

  The positions of the shallow groove portion 14, the intermediate groove portion 15, and the deep groove portion 16 of the cam groove 12 correspond to the fully open position, the half open position, and the closed position of the shutter portion 3, respectively. Further, in the cam groove 12, the guide protrusion 18 on the inner periphery of the rotating body 4 has a shallow groove portion 14 (= the fully open position of the shutter portion 3) → a middle groove portion 15 (= a half open position of the shutter portion 3) → a deep groove portion 16 (= the shutter). (The closed position of the portion 3) → (repeated similarly from the shallow groove portion 14) in order.

  Next, the usage state of the push-type register of this embodiment will be described.

  In this push-type register, the advancing / retreating shaft portion 6 urged in the direction of the shutter portion 3 and the shutter portion 3 are connected in the casing 1 attached to the indoor side, and the shutter portion 3 is always urged in the opening direction. When the open state of the shutter unit 3 is adjusted, the shutter unit 3 is pushed toward the casing 1.

  Then, the advance / retreat shaft portion 6 connected to the shutter portion 3 is displaced against the urging body 4 accommodated in the casing 1 against the urging force, and the guide protrusion 18 on the inner periphery of the rotator 4 is moved forward and backward. 6 is guided by the cam groove 12 on the outer periphery of the shaft 6 and is relatively displaced in the axial direction from the original position in the cam groove 12 (the shallow groove portion 14, the middle groove portion 15 or the deep groove portion 16). When the push-in is released, the next position (the shallow groove portion 14, the middle groove portion 15 or the deep groove portion 16 adjacent to the original position) is guided. Specifically, the shallow groove portion 14 (= the fully open position of the shutter portion 3) → the middle groove portion 15 (= the half open position of the shutter portion 3) → the deep groove portion 16 (= the closed position of the shutter portion 3) → (the same from the shallow groove portion 14) And repeat).

  Here, the positions of the shallow groove portion 14, the middle groove portion 15 and the deep groove portion 16 of the cam groove 12 correspond to the fully open position, the half open position and the closed position of the shutter portion 3, so that the shutter portion 3 is in the fully open state. There is an advantage that the shutter can be set in a half-open state or a closed state, and the shutter can be adjusted in three stages of full-open, half-open and closed.

  Since the shutter can be adjusted in three stages of full open, half open, and closed, it can be applied to various push register applications.
