It is a vertical outer wall. As shown in FIG. 4, a fitting short cylinder 24 a that forms a part of the center hole 6 is provided around the center of the vertical outer wall surface 24 in a protruding wall shape. On the other hand, the vertical inner wall surface 23 is flush, but in this embodiment, a pair of upper and lower connecting pillars 25 extend in the horizontal direction at the center of the upper and lower ends of the vertical inner wall surface 23.

  Next, reference numeral 26 denotes an upper arcuate side wall, while 27 denotes a lower arcuate side wall corresponding to the side opposite to the upper arcuate side wall 26. Unnumbered small notches are formed at the inner ends of the central portions of the arc-shaped side walls 26 and 27, and the elastic engagement claws of the decorative cover 11 for the outer base 3 are engaged with these unnumbered small notches. Reference numerals 28 and 29 are left and right side walls that are perpendicular to the arc-shaped side walls 26 and 27, and the left and right side walls 28 and 29 are provided with spring-like protrusions similar to the inner base 2 in this embodiment. Of course, a plurality of spring-like protrusions may be provided depending on the design. The structure of the connecting column 25 of the outer pedestal 3 will also be described later.

(3) Specific Requirements of the Present Invention As described above, the handle seat of the door of the present invention constitutes a “seat or seat connection structure” with the “dual article” of the inner base 2 and the outer base 3. Therefore, the connection hole portion 21 of the inner pedestal 2 and the distal end portion of the connection column 25 of the outer pedestal 3 are characterized. In addition to this, there is a feature in the spring-like projecting portion 20 continuously formed on the left and right side walls 28 and 29 of the inner base 2.

  First, the configuration of the connecting column 25 of the outer pedestal 3 will be described with reference to FIGS. 4 and 5. As shown in FIG. 5, the root portion side 25a connected to the inner wall surface 23 of the outer pedestal 3 of the connecting column 25 has a slightly larger diameter than the distal end portion side 25b extending horizontally from the root portion side 25a. The length of the connecting column 25 is appropriately set in consideration of the thickness of the door and the inner base 2. A circumferential groove 31 and a locking rod 32 are provided on the distal end side of the circumferential groove 31 on the distal end side 25b. The circumferential groove 31 is slidably engaged with a starting end side inclined surface of a rail-shaped guide projection wall described later and an opposing surface continuous to the starting end side inclined surface, and is also engaged with an arcuate surface of the locking end hole. On the other hand, the locking bar 32 is slidably engaged with the outer vertical surface of the rail-shaped guide projection wall.

  Next, the configuration of the long hole-shaped connecting hole portion 21 of the inner base 2 will be described with reference to FIGS. In the present embodiment, a pair of elongated hole-shaped connecting hole portions 21 are provided on the concentric circles of the center hole 4 in a rotationally symmetrical manner corresponding to the number of connecting columns 25. The configuration of each elongated hole-shaped connecting hole portion 21 is the same. For example, as shown in FIG. 11, the long hole-shaped connecting hole portion 21 has an insertion start end hole 21a into which the connecting column 25 enters one end portion, and a guide that leads from the insertion start end hole to the locking end hole 21c at the other end portion. The inner peripheral surface (a part of the inner peripheral surface forming the long hole-shaped connecting hole portion 21) having the hole 21b and forming the guide hole 21b is directed from the inner edge a to the outer edge b. Thus, a rail-shaped guide projection wall 33 is formed for gradually pulling the locking rod 32 of the connecting column 25 in a sliding contact state. Therefore, the “fixing tool” is not necessary as the seat connection structure (characteristic 1).

  Thus, in this embodiment, a pair of rail-shaped guide protrusion walls 33 are formed in a state of being opposed (rotationally symmetric) on the side of the center hole 4 and on the side opposite to the center hole side (arc-shaped side walls 16 and 17). Yes. In addition, the rail-shaped guide protruding wall 33 includes a start-side inclined surface 33a at which the circumferential groove 31 of the connecting column 25 starts to rise in the circumferential direction in which the insertion tip side 25b of the connecting column 25 is guided, and the start-side inclined surface. It has a strip-shaped facing surface 33b that is continuous with the surface, and an arc-shaped locking surface 33c that is a locking terminal hole that follows the strip-shaped facing surface 33b. Further, the rail-shaped guide projection wall 33 has a long plate-like outer vertical surface 33d orthogonal to each surface such as the start-side inclined surface 33a and the strip-shaped opposing surface 33b, and the outer vertical surface 33d is shown in FIG. As shown, the engagement rod 32 of the connecting column 25 is received, and the engagement rod 32 is guided from the above-described start end side inclined surface 33a to the arcuate locking surface 33c.

  Finally, the configuration of the springy protrusion 20 will be described. Each spring-like projection 20 is formed in the shape of a finger (for example, thumb) or a bowl as a whole, and an elastic hook whose base is connected to one end (upper end, lower end) of the straight side walls 18, 19. It consists of a portion 20a and a small protruding portion 20b which is formed so as to protrude from the inner surface of the elastic flange portion 20a and normally protrudes slightly from the inner wall surface 13 of the inner base 2. In other words, the small protruding portion 20b protrudes from the inner wall surface 13 of the inner base 2 in the axial direction.

  Thus, as shown in FIG. 14, when the small protrusion portion 20b is pressed against the inner wall surface 1a of the door 1, the elastic flange portion 20a faces the vertical outer wall surface 14 of the inner base 2 against its spring force. Displaces to warp. Therefore, when the inner and outer pedestals 2 and 3 are integrally connected, the spring-like projections 20 are pressed against the inner and outer wall surfaces 1a and 1b of the door 1, thereby preventing backlash of the seat ( Characteristic part 2).

(4) Operation First, as shown in FIG. 2, the connecting column 25 of the outer pedestal 3 is inserted into the through holes of the door 1 and the lock box 8, and as shown in FIG. The insertion start end hole 21 a of the long hole-like connecting hole portion 21 of the inner base 2 is fitted to the tip end portion (circumferential groove 31 and engagement flange portion 32) of the column 25. Next, as shown in FIG. 13, the inner base 2 is rotated in a predetermined direction (counterclockwise direction indicated by an arrow). When the inner pedestal 2 is rotated in a predetermined direction, the engagement flange 32 of the connecting column 25 is guided to the rail-shaped guide projection wall 33 from the insertion start end hole 21a as shown in FIG. At this time, the engagement flange 32 of the tip is guided by the outer vertical surface 33d of the rail-shaped guide projection wall 33, and the peripheral groove 31 of the tip is guided by the rail-shaped guide. It climbs up the start side inclined surface 33a of the projecting wall 33 and reaches the belt-like facing surface 33b. When the inner pedestal 2 continues to rotate in a predetermined direction, as shown in FIG. 14C, the engagement flange 32 at the distal end shifts from the guide hole 21b to the locking terminal hole 21c. When the engagement flange 32 at the distal end moves to the engagement terminal hole 21c, the circumferential groove 31 at the distal end engages with the arc-shaped engagement surface 33c.

  Therefore, in the present invention, the elongated hole-shaped connecting hole portion 21 has an insertion start end hole 21a into which the connecting column 25 enters one end portion, and a guide hole extending from the insertion start end hole to the locking end hole 21c at the other end portion. 21b, and the inner peripheral surface forming the guide hole 21b is a rail that gradually draws the locking rod 32 of the connecting column 25 from the inner edge a toward the outer edge b in a sliding contact state. Therefore, the inner and outer pedestals 2 and 3 can be integrally connected (coupled) so as to draw each other without using a “fixing tool”. Further, when the inner and outer pedestals are connected (coupled), as shown in FIG. 14, each spring-like projection 20 is pressed against the inner and outer wall surfaces 1 a and 1 b of the door 1, thereby preventing the seat from being loose. .

  In the example shown in the embodiment of the invention, the inner base 2 is provided with a plurality of connecting hole portions 21 on the concentric circles of the center hole 4, and the inner peripheral surface of the connecting hole portion 21. Further, a rail-shaped guide projection wall 33 is formed in a rotationally symmetrical manner to gradually draw the locking rod 32 of the connecting column 25 of the outer pedestal 3 in the sliding contact state from the inner edge to the outer edge. Although not specifically shown in the example of the design change of this embodiment, for example, the inner base 2 and the outer base 3 may be provided with the connecting hole portion 21 and the connecting pillar 25 having the locking rod 32, respectively. In such an embodiment, the connecting column 25 of the inner base 2 is used as the insertion start end hole of the connecting hole portion 21 of the outer base 3, while the connecting column 25 of the outer base 3 is used as the connecting hole portion 21 of the inner base 2. Since the inner and outer pedestals 2 and 3 need to be rotated by a predetermined amount so as to squeeze in opposite directions, the left and right through holes for the connecting pillars 25 inside and outside the lock box are respectively It is necessary to form in an arc-shaped guide hole.

  In addition, it is desirable that the connecting hole portion 21 of the inner pedestal 2 and the connecting pillar 25 of the outer pedestal 3 are plural as in the embodiment, but the connecting hole portion 21 and the connecting pillar 25 may be “single”. Is possible. Further, in the embodiment, the spring-like protrusions 20 are provided symmetrically in the left-right direction, but are not necessarily symmetrical.

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