Abstract

PROBLEM TO BE SOLVED: To solve the problems with conventional technologies of a general structure utilizing pressing force of a cylinder or pressing by a flash board for a waterproof door that adhesiveness and fastening on a mullion is not sufficient, and problems with other technologies described in literatures of a structure that does not press a packing and therefore does not offer water-tightness effect, although tightening has been intensified sequentially using different distances of eccentricity of an eccentric cam.SOLUTION: A waterproof door of the present invention is installed for waterproofing a subway, an underground structure for a subway, and an above-ground structure. An eccentric cam is provided on a side of a mullion at an entrance/exit exposed to water pressure, the eccentric cam having a cam surface biased toward a side of the mullion not exposed to water pressure. The eccentric cam is pressed against a side of the waterproof door exposed to water pressure, at the same time pressing a watertight elastic body on a side of the waterproof door not exposed to water pressure. Wedge tightening is attempted between one wedge disposed on a side of a waterproof door body exposed to water pressure and the other wedge on the cam surface of the eccentric cam. The eccentric cam and the watertight elastic body enable the waterproof door to adhere to and be tightened on the mullion.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a watertight and shield between a vertical stand and a waterproof door, or a watertight and shielded waterproof door for the purpose of preventing the waterproof door from being stolen, or an antitheft device.

  In a waterproof door, a structure that is performed in combination with the standing up of the waterproof door is known as means for pressing a water stop material (packing) to achieve water tightness. For example, there is a “waterproof door device” described in Japanese Patent Application Laid-Open No. 2014-114619. In addition, a structure that uses water pressure to make water tight by using a corner drop (waterproof door) is known. For example, there is a “corner drop” described in JP-A-11-158850. In any case, this is an auxiliary method and does not have a structure intended to actively waterproof the waterproof door. In addition, there is a structure that supports the waterproof sheet in a watertight manner using a cam mechanism. There exists Unexamined-Japanese-Patent No. 2014-136889. The frame is moved by the eccentric cam member, and the waterproof sheet is held in a watertight manner between the support frame and the elastic member. It is simply tightening when the eccentric cam is moved by an eccentric distance (difference in moving distance).

  In other fields, there is a “swivel table locking device” described in Japanese Patent Application Laid-Open No. 2004-142081 as a locking mechanism. This invention discloses a structure in which a turning table is tightened by a cam mechanism (an eccentric contact member).

  The prior art is a general structure by pressing with a cylinder or pressing with a corner drop, and it is considered that novelty is not visible. Reference (3) uses the fact that the eccentric distances of the eccentric cams are different, so that tightening is strengthened sequentially. However, it is not a structure that presses the packing at the same time, and it is considered that a watertight effect cannot be expected.

  In view of the above, the present invention proposes a structure in which the waterproof door is pressed against the watertight elastic body of the vertical or the facing surface of the vertical by an eccentric cam provided on the vertical. In addition, by installing the watertight elastic body and the eccentric cam on the same line in the same flow direction (water pressure direction P), a uniform pressing force can be applied to the watertight elastic body, and the burden on the waterproof door can be reduced. For example, there is a feature that there is no obstacle even if the waterproof door is made of other than metal.

  The present invention proposes claims 1 to 5, whereby the waterproof door can be pressed against the watertight elastic body of the vertical or the facing surface of the vertical by the eccentric cam provided on the vertical. In addition, by installing the watertight elastic body and the eccentric cam on the same line in the same flow direction (water pressure direction P), a uniform pressing force can be applied to the watertight elastic body, for example, the burden can be reduced. Or, it is an invention that opens the way to practicality, such as that there is no obstacle even if the waterproof door is made of other than metal.

The invention of claim 1 is an underground structure such as a subway, a basement, a garage, or a watertight and shielded waterproof door installed for waterproofing a ground structure of a factory or a building, or an antitheft device.
Eccentric cams with cam surfaces that are biased toward the anti-hydraulic pressure-fitting side are respectively provided on the side of the vertical hydraulic pressure-fitting side provided at the entrance and exit of the structure, and each eccentric cam is pressed against the hydraulic pressure-fitting side of the waterproof door. At the time of pressure contact, one pair of watertight elastic bodies provided on the anti-water pressure side of the waterproof door can be pressed, and one wedge provided on the water pressure side of the waterproof door body and the other cam surface of the eccentric cam It is a watertight and shielded waterproof door or an anti-theft device that can be tightened between the wedges of the doors, and is provided with a fastening means in the gap between the vertical doors and the waterproof door. By the cam, the waterproof door can be pressed against the vertical watertight elastic body or the vertical surface of the vertical wall. In addition, by installing the watertight elastic body and the eccentric cam on the same line in the same flow direction (water pressure direction P), a uniform pressing force can be applied to the watertight elastic body, for example, the burden can be reduced. Or, it is an invention that opens the way to practicality, such as that there is no obstacle even if the waterproof door is made of other than metal.

  According to a second aspect of the present invention, the eccentric cam is a watertight / shielding or anti-theft device for a waterproof door provided in a pair in the vertical direction on each side. The achievement of the object of the first aspect and the highest efficiency of the eccentric cam There is an actual benefit that can propose a suitable installation position.

  According to the invention of claim 3, the cam surface of the eccentric cam is configured such that the movable side X facing the tightening direction is short and the driven side X1 facing the anti-tightening direction is long with respect to the shaft center of the eccentric cam. The waterproof door is watertight and shielded or an anti-theft device, and has the advantages of achieving the object of claim 1 and proposing the most efficient shape as an eccentric cam.

  The invention of claim 4 is a waterproof / waterproof or anti-theft device for a waterproof door in which the other wedge is formed on the cam surface of the eccentric cam. There is an actual advantage that can propose a cam surface useful as a wedge and a wedge structure opposite to this.

  According to a fifth aspect of the present invention, the tightening means is a key provided in a vertical position, and is composed of a key piece that moves forward and backward toward the waterproof door and a key hole of the waterproof door, and the key piece is engaged with and disengaged from the key hole. It is a watertight / shielding or anti-theft device for waterproof doors, and has the advantage of achieving the object of claim 1 and proposing fastening means.

Scaled overhead view showing the entire waterproof door of the present invention, partially omitted Front view showing the entire waterproof door of the present invention, partially omitted The enlarged plan view illustrating the relationship between the eccentric cam and the wedge provided on both of the frame and the waterproof door of the present invention, and the watertight elastic body. FIG. 3 is a schematic cross-sectional view showing a relationship between a vertical, a movable shaft, and an eccentric cam. It is a schematic view from each direction of the eccentric cam, (A) is a plan view, (B) is a bottom view, (C) is a front view, (D) is a rear view, (E) is a right side view, F) is a left side view, and (G) is a perspective view. A bird's-eye view showing the relationship between the claw holder and the claw holder with a key 5 is a side view of a part of FIG.

  In the figure, 1 and 1 'are pairs of frames (the structure of the pair is the same as that of one of the symbols), and the structure (structure) of a basement, an underground parking lot, an underground building such as a subway, or a factory. It is erected at both ends of a passage, a waterway, or a river (an underground building, a structure such as a factory is a building H). The vertical frame 1 is U-shaped, and has a structure in which the left and right sides are confronted, and has an opening 100 in the facing direction. A rotating shaft 2 is erected on the water pressure opposite side Y of the stand 1 and spaces 101 and 102 for accommodating a pair of eccentric cams 3 described later are formed. The eccentric cam 3 has a structure that sinks into the spaces 101 and 102, and has a structure that does not get in the way when the waterproof door body 5 is inserted into the opening 100 of the stand 1.

  The eccentric cam 3 is shown in detail in FIG. 4, and in FIG. 3, its movement and its function are shown. The eccentric cam 3 is secured to the upper and lower sides of the pair of rotating shafts 2 and 2 '(four eccentric cams 3), and the movable side X facing the tightening direction Z is seen in plan view. Since the driven side X1 which is short and faces in the anti-tightening direction Z1 is long, it rotates from the broken line state in FIG. 3 to the solid line state. By this rotation, the wedge 300 (reverse cutting shape) of the cam surface 3a and the wedge 500 (cutting shape) of the waterproof door body 5 are in a pressure contact state, and the waterproof door body 5 is lowered (floor surface or ground). Etc.) (watertight with the floor surface etc.). In other words, the cam surface 3a has a vertically-cut wedge 300 as viewed from the side, and the reverse-cut wedge 300 rotates in the tightening direction Z while being waterproof. In this structure, the wedge-shaped wedge 500 provided on the side Y against the water pressure of the main body 5 is sequentially pushed down. Therefore, there is a feature that the waterproof door body 5 can be pushed down smoothly and smoothly. In addition, as shown in the figure, the shape of the eccentric cam 3 in the circumferential direction is such that the length of the driven side X1 (deviation) with respect to the length of the movable side X (the distance from the pivotal attachment to the tip of the eccentric cam 3). Since the distance from the pivot point to the tip of the lead cam 3 is long (the distance is large), the cam surface 3a is distorted (resulting in an eccentric relationship), and the rotating shaft 2 rotates as described above. Thus, the wedge 300 of the cam surface 3a sequentially presses the wedge 500 of the waterproof door body 5 (waterproof door body 5 itself) against the opposite water pressure side Y1. Then, the waterproof door body 5 is pressed against the anti-hydraulic pressure side Y1 of the waterproof door body 5 to the upper and lower ends 1a and 1b of the anti-water pressure side Y1 of the waterproof door body 5 and the bottom surface 100a of the anti-hydraulic side Y1 of the opening 100. Then, the watertight elastic body 6 provided (watertight rubber, packing, etc.) is pressed (on the opposite side Y1 of the waterproof door body 5). It should be noted that the tightening release of the eccentric cam 3 and the opening of the watertight elastic body 6 can be achieved by the reverse operation described above, and then the removal of the waterproof door body 5 (waterproof door) from the stand 1 is as described above. The reverse of the operation.

  As described above, the water-tightness of the waterproof door body 5 (waterproof door) with the floor or the like at the lower end, and the watertightness of the waterproof door body 5 (waterproof door) against the opposite water pressure Y1 and the vertical wall 1 (of the watertight elastic body 6). Water-tightness by pressing) makes it possible to achieve water-tightness of various passages, water channels, or spaces such as walls and gates.

  In addition, although the rotating shaft 2 stands upright in the vertical stand 1, it is an example and is not limited. Therefore, it is possible to stand outside the vertical frame 1.

  In the figure, reference numeral 10 is an example of the anti-theft device. The key piece 12 is provided in the casing 11 of the waterproof door body 5 so as to be able to move in and out, and the waterproof door body 5 that receives the key piece 12 is provided. A key hole 13 attached to 5 and a key 15 (switch) for operating the key piece 12 are main components. The anti-theft device 10 is operated in a state in which the eccentric cam 3 is operated and the waterproof door body 5 is fastened in the frame 1. Therefore, for example, it is useful for theft prevention of the waterproof door main body 5 and the like, and acts effectively for preventing the withdrawal during heavy rain. In addition, the appearance structure of the key piece 12 by the key 15 is arbitrary.

  Each structure described above is a description of a preferred example of the present invention. Therefore, the present invention is not limited to the above-described embodiments, and structures that change a part of the configuration within the scope of the invention, structures that can achieve the same features and effects, and the like are within the scope of the present invention. It is.
