DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Hereinafter, an embodiment of the present invention will be described with reference to Fig. 1(A) to Fig. 5(C). Fig. 1 is a front view showing an entire door opening / closing device for a vehicle facility according to one embodiment of the present invention, with (A) showing the door in a closed state and (B) showing the door in an open state. Fig. 2 is a plan view of the guide rail shown in Fig. 1. Fig. 3 is a cross-sectional view taken along line AA in Fig. 2, with (A) showing the door in a closed state and (B) showing the door in an open state.

[0018] As shown in FIG. 1, a vehicle facility door opening / closing device 1 according to one embodiment of the present invention comprises a side-opening door 2 which opens and closes in the left-right direction, a drive rail 3 which suspends the door 2 so that it can open and close in the left-right direction, a drive means 4 which opens and closes the door 2, and a guide rail 5 which is arranged under the door 2.

[0019] The opening / closing door device 1 is disposed at an entrance / exit 11 through which vehicles (including all vehicles with wheels) pass. The vehicle facility is, for example, a mechanical parking device. Mechanical parking devices include various types of mechanical parking devices such as horizontal circulation type, elevator type, and vertical circulation type. Note that the term "vehicle facility" is not limited to mechanical parking devices, but is intended to include all equipment equipped with an entrance / exit 11 through which vehicles pass over guide rails 5 while rolling their wheels.

[0020] The opening and closing doors 2 include, for example, a pair of high-speed doors 21 that move a long distance when opening and closing, and a pair of low-speed doors 22 that move a short distance when opening and closing. The pair of high-speed doors 21 are arranged to move on the same axis, and are configured to close the center of the entrance 11 when the opening and closing doors 2 are in a closed state. The pair of low-speed doors 22 are arranged to move on the same axis, and are configured to close the outer space adjacent to the high-speed doors 21 when the opening and closing doors 2 are in a closed state.

[0021] The high-speed door 21 and the low-speed door 22 are configured to be movable on different axes arranged in the front and rear. The high-speed door 21 and the low-speed door 22 may be linked by an interlocking device so that the time required for opening and closing them is the same.

[0022] In this embodiment, the case where the opening and closing door 2 is a double-door that moves in both left and right directions when opening and closing is described, but the opening and closing door 2 may be a single-door that moves in only one direction, left and right, when opening and closing. Also, in this embodiment, the opening and closing door 2 is made up of a total of four doors, but the number of doors that make up the opening and closing door 2 is arbitrary, and in the case of a double-door, it is made up of an even number of doors, and in the case of a single-door, it is made up of an odd or even number of doors.

[0023] The driving means 4 includes, for example, a driving motor and a power transmission means that converts the rotational motion of the driving motor into linear motion and transmits the linear motion to the opening and closing door 2. The power transmission means may be a belt drive device or a chain drive device. The driving means 4 may also be a linear actuator or the like.

[0024] As shown in FIG. 1(A), when the opening / closing door 2 is in the closed state, the entrance / exit 11 is closed by the high-speed door 21 and the low-speed door 22. When the drive means 4 is actuated, the high-speed door 21 moves a distance of approximately two doors and the low-speed door 22 moves a distance of approximately one door, and the entrance / exit 11 is opened as shown in FIG. 1(B).

[0025] The guide rail 5 includes a recess 51 formed in the floor surface 12 of the vehicle facility along the opening and closing direction of the opening and closing door 2, and a protrusion 52 disposed at the bottom of the recess 51 for guiding the opening and closing door 2. The recess 51 is formed by a base plate 53 embedded in the floor surface 12. The base plate 53 has an elongated groove shape in the opening and closing movement direction of the opening and closing door 2, for example, as shown in Figures 2 and 3(A).

[0026] The base plate 53 has a bottom 53a disposed at the center, and inclined surfaces 53b disposed on both sides of the bottom 53a so as to open at the top. The base plate 53 defines a recess 51 having a shape in which the width Wt of the top is wider than the width Wb of the bottom. The inclined surfaces 53b have an inclination angle of, for example, 30 to 60° (in other words, 120 to 150° in terms of the opening between the bottom 53a and the inclined surfaces 53b).

[0027] The base plate 53 may include a pedestal 54 for adjusting the height of the base plate 53, and a fixing plate 55 for fixing the base plate 53 to the foundation of the floor surface 12. Note that the height adjustment means and fixing means of the base plate 53 are not limited to the configurations shown in the figures.

[0028] The pedestal 54 is, for example, a plate member arranged along the longitudinal direction of the bottom 53a of the base plate 53. The fixing plate 55 is, for example, a plate member arranged at a predetermined interval along the longitudinal direction of the base plate 53. Both ends of the fixing plate 55 are fixed to the foundation of the floor surface 12 by fasteners such as bolts.

[0029] The protrusion 52 is a portion formed to protrude upward from the bottom 53a along the longitudinal direction of the base plate 53. The protrusion 52 may be formed separately from the base plate 53, or may be formed integrally with the base plate 53.

[0030] 2, the protrusions 52 include a first protrusion 52a for guiding the high-speed door 21 and a second protrusion 52b for guiding the low-speed door 22. The arrangement and number of the protrusions 52 are determined according to the configuration of the opening and closing door 2. The protrusions 52 are formed to be at approximately the same height as the floor surface 12.

[0031] 1(A) and 3(B), the opening and closing doors 2 (high-speed door 21 and low-speed door 22) are provided with guide shoes 23 guided by protrusions 52. The guide shoes 23 are sliding bodies arranged at predetermined intervals on the bottom of each door, and are provided with grooves 23a into which the protrusions 52 can be inserted.

[0032] Incidentally, a sensor that detects whether or not a vehicle has passed through the entrance / exit 11 is often disposed near the opening / closing door 2. If the protrusion 52 is formed higher than the floor surface 12, the vehicle may climb over the protrusion 52 when passing through the entrance / exit 11, causing the height dimension of the vehicle to fluctuate, and the measurement accuracy of the sensor may become unstable.

[0033] Therefore, in this embodiment, in order to form the protrusion 52 at approximately the same height as the floor surface 12, the recess 51 is formed in the floor surface 12 by the base plate 53. With this configuration, it is possible to stabilize the measurement accuracy of the sensor and to reduce the impact when a vehicle passes. In addition, the opening and closing door device 1 according to this embodiment can also be applied to an entrance / exit 11 where no sensor is provided and where wheelchairs, forklifts, transport carts, etc. pass.

[0034] Furthermore, a foreign object X such as a pebble may be brought into the vehicle facility by the vehicle and may get caught in the recess 51 of the guide rail 5 as shown in Fig. 3(A). In this case, if the side surface forming the recess 51 is configured by a vertical surface instead of the inclined surface 53b, the foreign object X may get caught between the guide shoe 23 and the guide rail 5, which may hinder the opening and closing movement of the opening and closing door 2.

[0035] Therefore, as shown in FIG. 3(B), in this embodiment, the side portion of the recess 51 is configured with an inclined surface 53b so that the foreign object X that has entered the recess 51 can be repelled by the guide shoe 23 and removed from the recess 51.

[0036] 4A and 4B are diagrams showing modified examples of the guide rail, in which (A) shows a first modified example and (B) shows a second modified example. In these modified examples, a dust collection groove 56 is formed between the bottom portion 53a and the inclined surface 53b along the opening and closing direction of the opening and closing door 2.

[0037] In a first modified example shown in Fig. 4(A), dust collection groove 56 is formed by forming undulating portion 53c between bottom portion 53a and inclined surface 53b. In a second modified example shown in Fig. 4(B), dust collection groove 56 is formed by forming recessed portion 53d between bottom portion 53a and inclined surface 53b. Note that recessed portion 53e may be added to the center of bottom portion 53a.

[0038] By forming the dust collection groove 56 in this manner, foreign matter that gets into the guide rail 5 can be collected in the dust collection groove 56, further reducing the possibility of foreign matter getting caught in the guide shoe 23 when the opening and closing door 2 is opened and closed.

[0039] 5 shows modified examples of the guide shoe, where (A) shows a first modified example, (B) shows a second modified example, and (C) shows a third modified example. These modified examples are such that the guide shoe 23 is provided with a dust removal section 24 that sweeps out foreign matter to the outside of the recess 51. In each figure, the arrow indicates the movement direction of the opening and closing door 2.

[0040] The dust removal part 24 has a surface formed so that the width narrows toward the tip, and is configured so that when it collides with a foreign object, it bounces the foreign object off toward the outside of the guide rail 5. The surface forming the dust removal part 24 may be flat or curved.

[0041] In a first modified example shown in Fig. 5(A), the dust removing section 24 is formed by a machined surface formed on the guide shoe 23. In a second modified example shown in Fig. 5(B), the dust removing section 24 is formed by a guide block 25 arranged on the guide shoe 23. In a third modified example shown in Fig. 5(C), the dust removing section 24 is formed by a guide plate 26 arranged on the guide shoe 23.

[0042] In this way, the dust removing unit 24 may be configured integrally with the guide shoe 23, or may be configured separately. Although Fig. 5(A) to Fig. 5(C) show the case where the dust removing unit 24 is disposed at one end of the guide shoe 23, the dust removing unit 24 may be disposed at both ends of the guide shoe 23.

[0043] The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the present invention. [Explanation of symbols]
