JP 2006-225952 A

  However, in the above-described conventional example, it is necessary to rotate the lid body in a plane orthogonal to the pulling direction during the opening operation, and thus the lid body may come into contact with the apparatus main body during the rotation operation.

  As shown in FIGS. 5 (a) and 5 (b), this problem can be solved by connecting the lid 2 to the apparatus main body 1 so as to be able to stand up and rotate in the lying down direction. In order to prevent interference with the apparatus main body 1 in the vicinity of the rotating shaft 10 of the body 2, it is necessary to chamfer the corners as shown by arrows in FIGS. There is a disadvantage that the degree is low.

  The present invention has been made to solve the above-described drawbacks, and an object of the present invention is to provide an apparatus with a lid with a high degree of freedom in design around the lid mounting portion.

  The device with a lid is formed by closing the opening 3 of the device body 1 with a lid 2 so that the opening can be opened. The lid 2 closes the opening 3 while being placed on or stacked on the lid 2 in the closed posture, and the opening 3 is rotated around the connecting portion 4 to the apparatus main body 1 so that the opening 3 is rotated. Opened.

  The connecting portion 4 of the lid 2 to the apparatus main body 1 can be freely moved by a predetermined stroke in a direction in which the stacking boundary with the apparatus main body 1 is separated (hereinafter, this direction is referred to as “front” in the present specification). Yes, the lid 2 is opened by first pulling the lid 2 forward and then rotating it up around the connecting portion 4.

  The connecting portion 4 can be formed as a protrusion or a recess. When the connecting portion 4 is formed as a protrusion, the connecting portion 4 can be freely rotated in the apparatus main body 1 and moved back and forth. A groove that is long in the front-rear direction to be freely received is formed as the connected portion 4. Moreover, when forming the to-be-connected part 4 by the side of the apparatus main body 1 as a protrusion, the connection part 4 is formed as a ditch | groove.

  In the present invention in which the opening and closing operations of the opening 3 are performed by standing and lying down, the lid body 2 is rotated in parallel with the apparatus body 1 at the drawing position on the front surface of the apparatus body 1, as in the above-described conventional example. Since there is no need to worry about the collision of the lid body 2 with the front surface of the apparatus when the lid body 2 is rotated, it is possible to prevent the apparatus body 1 from being damaged due to the operation.

  Further, the connecting portion 4 of the lid body 2 to the apparatus main body 1 can be translated forward, and the rotation center position at the time of the rotation operation can be moved to the front, that is, a higher position of the apparatus main body 1. When the rotation center is increased, as shown in FIG. 5B, it is necessary to form chamfers or the like at the corners in order to prevent the corners of the lid 2 from colliding with the device body 1 during the rotation operation. And freedom of design is improved.

  Further, the rotation restricting portion 5 informs the user that it is impossible to stand up and rotate with the connecting portion 4 side being a rotationally moving end by pulling out the connecting portion 4 side that is movable in the front-rear direction, and breaking by unreasonable operation. To prevent. The rotation restricting portion 5 is formed as a column body that is detachably fitted into a hole-like restriction target portion formed on the lid body 2 side, or is fitted into a restriction target portion formed as a column body. It can also be formed as a fitting hole.

In addition, the lidded device
The apparatus body 1 is formed with a recessed groove-shaped lid fitting recess 8 that is open on both sides, and the lid 2 connects the connecting portion 4 to a pair of opposing walls of the lid fitting recess 8. Is fitted in the lid fitting recess 8,
In addition, the lid 2 can be configured by forming a pair of knob operation walls 9 that are exposed to the side opening portion of the lid fitting recess 8 in the fitted state and serve as a pinch allowance when the lid 2 is operated. .

  In a state where the lid body 2 is fitted in the concave groove-like lid fitting recess 8, the connecting portion 4 forming side almost contacts the pair of opposing walls of the lid fitting recess 8 and cannot be operated by the user. The pair of knob operation walls 9 that are generally the only operable parts for the opening operator reminds the user of the knob operation of the knob operation wall 9 by the opening operator.

  When an appropriate operation such as pulling out, pushing in, or rotating to the lid 2 is performed while the knob operation wall 9 is picked, a door opening operation scheduled for the drawer operation in the front-rear direction or obliquely forward occurs. . In the case where the user does not know the exact opening operation in order to fulfill the function of a guide that informs the user of the correct opening procedure for a series of trial operations up to the opening of the door. Even so, the door opening operation can be performed without difficulty.

  According to the present invention, since it is not necessary to chamfer around the rotation center, the degree of design freedom around the lid mounting portion can be increased.

  FIG. 1 shows an embodiment of the present invention applied to a locking device. The locking device is an entrance lock that is used by being fixed to the outdoor side wall surface of the entrance door, and is formed by connecting an operation handle 1b to a base portion 1a that is vertically fixed to the door body 11.

Is covered with a lid body 2 that closes.

  The entrance lock configured as described above is used together with the indoor side lock device 12 fixed to the indoor side wall surface of the door body 11. The thumb turn device 12a is fixed to the indoor side locking device 12 at a position facing the cylinder lock 1c, and allows manual locking / unlocking operation from the indoor side.

  Details of the opening 3 of the base 1a are shown in FIG. First, a lid fitting recess 8 is formed in the base portion 1a, and a circular opening 3 is formed in the bottom wall 8b of the lid fitting recess 8 so as to penetrate in the front-rear direction. The lid fitting recess 8 is formed in a recessed groove shape that is open in the left-right direction, and the hinge protrusion fitting groove 13 and the click protrusion fitting groove 14 are formed in each of the upper and lower opposing walls 8 a of the lid fitting recess 8. Are recessed at positions facing each other.

  The click protrusion fitting groove 14 is formed at two positions near the center in the left-right direction and the right side. The front ends of these click protrusion fitting grooves 14 are positioned slightly forward of the bottom wall 8b of the lid fitting recess 8, and will be described later on a step 14a formed on the upper and lower opposing walls 8a of the lid fitting recess 8 by the front end surface. The click protrusion on the lid 2 side is locked. Further, the hinge protrusion fitting groove 13 is formed in the vicinity of the left side. The front end face of the hinge protrusion fitting groove 13 is positioned slightly above the click protrusion fitting groove 14, and a step 13 a formed on the front end face determines the end of the forward drawing stroke of the lid 2.

  The click projection fitting groove 14 and the hinge projection fitting groove 13 are opened to the rear of the base portion 1a so that the base portion 1a can be molded with a molding die having a split direction in the front-rear direction. It is formed as a through groove or through hole.

  Further, a rotation restricting portion 5 is formed on the bottom wall 8 b of the lid fitting recess 8. In this embodiment, the rotation restricting portion 5 is formed as a columnar body protruding forward from the bottom wall 8b of the lid fitting recess 8 and is fitted into a restriction target portion 15 of the lid 2 described later. As shown in FIG. 4D, the rotation restricting portion 5 is formed to have a height dimension such that the fitting with the restricting target portion 15 is released when the lid body 2 moves to the end of the drawing stroke.

  On the other hand, as shown in FIG. 3, the lid body 2 has four sides of the top plate portion 6 having a front view shape (rectangular shape in this embodiment) substantially matching the front view shape of the lid fitting recess 8. The knob operation wall 9 and the connecting portion forming wall 2a are erected on the edge to form a substantially box shape. The connecting portion forming wall 2a protrudes from the opposing edge of the top plate portion 6 corresponding to the upper and lower opposing walls 8a of the lid fitting concave portion 8, and clicks with the hinge forming leg portion 7 by the slit 2b formed at a predetermined position. The leg 16 is divided. The lid 2 is made of a synthetic resin material, and elastic deformation is imparted to the hinge forming leg 7 and the click leg 16 separated from the adjacent part via the slit 2b.

  As shown in FIG. 4A, the click leg 16 is disposed at a position facing the click protrusion fitting groove 14 on the lid fitting recess 8 side. As shown in FIG. 3B, a hemispherical click protrusion 16 a protrudes from the free end of the click leg 16 and fits in the click protrusion fitting groove 14. Moreover, the hinge formation leg part 7 is arrange | positioned in the position which opposes the hinge protrusion fitting groove | channel 13 of the lid fitting recessed part 8, and the hinge protrusion part 4 (connection part 4) protrudes at a free end. The hinge protrusion 4 is formed in a cylindrical shape in order to prevent careless detachment from the hinge protrusion 4 fitting groove 13.

  The lid 2 formed as described above is performed by fitting the hinge protrusion 4 into the hinge protrusion fitting groove 13. The fitting operation can utilize the elastic deformability of the hinge forming leg 7, and the hinge forming leg 7 bent by the pushing operation to the rear of the hinge forming leg 7 has the hinge protrusion 4 as the hinge protrusion. When the fitting groove 13 is reached, the original shape is restored by the elastic restoring force, and the fitting operation of the hinge protrusion 4 to the hinge protrusion fitting groove 13 is completed.

  As shown in FIG. 1, the lid 2 corresponds to the closed position when the lid is fitted in the lid fitting recess 8, and the top plate 6 constitutes an extended surface of the front wall of the base portion 1 a at the closed position. The knob operation wall 9 constitutes an extended surface of the left and right wall surfaces of the base portion 1a. At this closed position, the click protrusion 16a is fitted in the click protrusion fitting groove 14 to restrict the forward movement of the lid body 2, and holds the lid body 2 at the closed position. Further, as shown in FIG. 4C, the rotation restricting portion 5 is fitted in the fitting hole (restriction target portion 15) of the lid body 2 at the closed position, and the hinge protrusion 4 of the lid body 2. Both the surrounding rotation (rotation in the direction of arrow A in FIG. 4C) and the rotation having the vicinity of the hinge protrusion 4 as the rotational movement end (rotation in the direction of arrow B in FIG. 4C) are regulated. .

  In order to shift the lid 2 to the open posture, first, the knob operation wall 9 is picked with a finger and pulled forward as shown in FIG. After the click protrusion 16a interferes with the step of the click protrusion fitting groove 14 by the pulling operation of the lid body 2, the click leg 16 is elastically deformed and gets over the step 14a. When the pull-out operation is further continued, the hinge protrusion 4 comes into contact with the front end of the hinge protrusion fitting groove 13 and reaches the stroke end in the pull-out direction.

  In this state, the rotation restricting portion 5 is almost detached from the fitting hole 15, and then the opening 3 is opened when the lid 2 is rotated around the hinge protrusion 4 as shown in FIG. 4 (e). Thus, the unlocking operation to the cylinder lock 1c using the unlocking key becomes possible.
