This is extremely inconvenient for a physically handicapped person, and causes inconveniences such as scratching doors and wheelchairs.

  Second, the door is supported by an upper support rail, while a disabled person in a wheelchair has to operate the lower part of the door, which results in large stresses that are offset against the support rail. And it is difficult to open the door stably and smoothly.

  An object of the present invention is to provide a semi-automatic door device that solves the problems existing in the background art.

  In order to solve the above-described problem, the present invention provides a semi-automatic device having a door 3 that is slidably supported by a support rail mechanism 2 having an inclined support rail 2r that is inclined downward in a closing direction Fc, and that is manually opened and automatically closed. When configuring the door device 1, a magnet 5 is disposed on one of the door 3 or the fixed side portion 4 with respect to the door 3 so that the door 3 stops at at least one set open position Xs, and the magnet is disposed on the other. It is characterized in that an adsorbing section 6 for adsorbing 5 is provided.

  The semi-automatic door device 1 according to the present invention having such a configuration has the following remarkable effects.

  (1) Since the door 3 is stopped at at least one set open position Xs and is kept open, even a disabled person in a wheelchair can easily pass through the door 3 and is convenient for the disabled person. Can be increased.

  (2) It is possible to avoid a problem that the closing door 3 hits the wheelchair and damages the door 3 and the wheelchair.

  According to the semi-automatic door device 1 according to the present invention, according to the best mode, the door 3 is provided with the handle portion 7 arranged at a position that can be operated by a physically handicapped person of the wheelchair, and the door facing the support rail mechanism 2. A guide rail mechanism 8 for guiding the door 3 is provided on the opposite side of the door 3. Thereby, even if the wheelchair is physically handicapped, the door 3 can be easily opened by the handle 7 and the guide rail mechanism 8 can open the door 3 stably and smoothly.

  Next, preferred embodiments according to the present invention will be described in detail with reference to the drawings.

  First, the configuration of the semi-automatic door device 1 according to the present embodiment will be specifically described with reference to FIGS.

  In FIG. 1, reference numeral 3 denotes a door. The illustrated door 3 is a relatively lightweight Japanese-style door formed entirely of a wooden board B and a plastic board (or paper) P, and can secure light operation and quiet movement. In particular, the handle portion 7 is formed by a concave portion extending from the lower portion of the door 3 to the vicinity of the center so that both a healthy person and a disabled person in a wheelchair can operate without difficulty. Further, the upper end side and the lower end side of the door 3 are formed by inclined sides having a downward slope in the closing direction Fc.

  On the other hand, 11 indicates a vertical frame on the doorway side, and 12 indicates a vertical frame on the door pocket side. An inclined support rail 2r is installed between the upper ends of the vertical frames 11 and 12. In this case, as shown in FIG. 2, the inclination angle R of the support rail 2r is set to an appropriate angle in consideration of the weight of the door 3 so that the door 3 has a downward slope with respect to the closing direction Fc. . On the floor 13 between the lower ends of the vertical frames 11 and 12, there is laid a lower frame 14 having an inclined upper surface where the door 3 is inclined downward in the closing direction Fc. In this case, the lower frame 14 is for filling the gap between the door 3 and the floor surface 13 and is formed by a gentle slope having no steps in the traffic direction.

  As shown in FIG. 3, the support rail 2r has a rectangular frame shape in cross section, and has a slit S along the longitudinal direction in the center of the lower surface. On the other hand, a pair of spaced roller units 15a and 15b is mounted on the upper end side of the door 3, as shown in FIG. The pair of roller units 15a and 15b and the support rail 2r constitute the support rail mechanism 2. As shown in FIG. 2, one roller unit 15b includes a mounting plate 16 fixed to the upper end side (upper surface) of the door 3 with screws N, and a suspension pin 17 standing upright from the mounting plate 16. A roller support block 18 for supporting the upper end of the suspension pin 17, and four rollers 19 rotatably supported by a horizontal axis perpendicular to the moving direction and arranged on the front, rear, left and right sides of the roller support block 18. , And a pair of rollers 20 rotatably supported by a vertical axis perpendicular to the moving direction and arranged before and after the lower surface of the roller support block 18.

  In this case, since the mounting plate 16 functions as the suction portion 6, the mounting plate 16 is formed of a magnetic material such as a steel material to which the magnet 7 described later can be suctioned, and the position of one end of the mounting plate 16 is as shown in FIG. , So as to substantially coincide with the rear end of the door 3. The other roller unit 15a uses the same roller unit 15b. In this case, the roller unit 15a is attached to the front end of the door 3 and is attached so as to be symmetrical with respect to the roller unit 15b, so as to balance the front and rear weights. Thereby, the roller units 15a and 15b can be loaded inside the support rail 2r, and when loaded, as shown in FIG. 3, the rollers 19 are placed on the lower surface of the support rail 2r, The rollers 20 are engaged with the slits S of the support rail 2r, and the door 3 is slidably supported by the support rail mechanism 2.

  On the other hand, the magnet 5 is mounted on the fixed side portion 4 with respect to the door 3, that is, near the upper end of the vertical frame 12 on the door pocket side and facing one end of the mounting plate 16 as shown in FIG. 2. Accordingly, at the open position Xs where the door 3 is fully opened, one end of the mounting plate 16 is attracted to the magnet 5 and the door 3 can be stopped.

  Further, on the opposite side of the door 3 facing the support rail mechanism 2, a guide rail mechanism 8 for guiding the door 3 is provided. As shown in FIGS. 1 and 4, the guide rail mechanism 8 is provided on a lower end side (lower end face) of the door 3, and stands on the upper surface of the lower frame 14 and engages with the guide slit 31. The engaging pin 32 is provided. The guide slit 31 is formed at the center position on the lower end surface of the door 3 along the longitudinal direction, and the engaging pin 32 is rotatably supported by the support pin 33 and the upper end of the support pin 33. Roller 34 provided. Further, inside the guide slit 31, a flat bar 35 formed of, for example, a steel material for securing a vertical weight balance is fixed to the pair of roller units 15a and 15b. By providing such a guide rail mechanism 8 and the flat bar 35, the swing of the door 3 can be prevented, and in particular, even if the wheelchair is physically disabled, the door 3 can be opened stably and smoothly. A pair of wall panels 41 are provided on both sides on the door pocket side, and cover panels 42 are provided on both sides of the support rail 2r.

  Next, the operation (function) of the semi-automatic door device 1 according to the present embodiment will be described with reference to the drawings.

  First, the door 3 in the natural state is in the closed state shown in FIG. In this closed state, it is assumed that a physically disabled person in a wheelchair opens the door 3 and passes through the doorway. In this case, the disabled person in the wheelchair approaches the closed door 3 and opens the door 3 using the handle 7. At this time, the handle portion 7 is formed over the lower portion of the door 3 so that a physically handicapped person of the wheelchair can operate it without difficulty, and a guide rail mechanism 8 and a flat bar 35 are provided at the lower end of the door 3. Therefore, a physically handicapped person in a wheelchair can easily open the door 3 and open the door 3 stably and smoothly.

  On the other hand, if the door 3 is moved to the fully opened position Xs indicated by the phantom line in FIG. 2, the mounting plate 16 of the roller unit 15b comes into contact with the magnet 5, and the mounting plate 16 is attracted to the magnet 5. , The door 3 stops at the open position Xs. Therefore, the fully open state of the door (door 3) is ensured, so that even a disabled person with a wheelchair can easily pass through, and the convenience for the disabled person is enhanced. Further, a problem that the door 3 to be closed hits the wheelchair and damages the door 3 and the wheelchair is avoided.

  When the physically handicapped person passes through the doorway, the door 3 may be slightly pulled in the closing direction Fc using the handle 7. Thereby, the suction between the magnet 5 and the mounting plate 16 is released, and thereafter, even if the hand is released from the handle part 7, the door 3 moves along the inclined support rail 2r to the closed position Xc shown in FIG. I do. That is, the door 3 is automatically closed. In addition, a healthy person can open the door 3 as much as necessary and pass through, as in the case of a general door.

  Although the embodiment has been described in detail above, the present invention is not limited to such an embodiment, and a detailed configuration, shape, material, quantity, numerical value, and the like do not deviate from the gist of the present invention. Can be changed, added, or deleted arbitrarily.

  For example, an arbitrary position can be selected as the arrangement position of the magnet 5 and the attraction unit 6. In addition to the case where the door 3 is stopped at the fully opened position Xs, in the case of a wide door, the door 3 may be stopped at a predetermined open position Xs set before the fully opened position Xs. Further, the open positions Xs... May be set to a plurality of positions, such as one or two or more half-open positions and fully open positions. On the other hand, an electromagnet is used as the magnet 5, and when the first switch is turned on with the hand touching the handle 7 when opening, the electromagnet is excited, and the second switch is turned with the hand touching the handle 7 when closing. It is also possible to configure so that the excitation of the electromagnet is released by turning on, and the concept of the magnet 5 includes the electromagnet. The suction unit 6 also includes a magnet. In addition, although the example illustrated the door 3 for general houses, it is also suitable to be used for the door 3 in various facilities such as hospitals.
