Description

  The present invention relates to an inspection port device for a vertical wall of a building used for forming an inspection port in a vertical wall of a building, and to an inspection port structure of a vertical wall of a building using the same.

  As an example of wall inspection port equipment used to provide an inspection port for inspecting equipment such as piping and wiring in a wall of a building, JP-A-6-146317 (Patent Document 1) and JP-A-2001-2001 The ones described in JP-A No. 140460 (Patent Document 2) and JP-A-2005-139704 (Patent Document 3) have been proposed, but these inspection port devices frame the wall opening provided in the wall body. Since the frame body is fitted, and the lid that can be attached or detached is fitted to the frame body so that the inspection port formed by the frame body is closed with the lid body. External exposure is inevitable, and there is room for improvement in improving the appearance. In particular, in recent years, the demand for maintenance of piping has been increasing, and inspection ports have been increasingly installed on the visible surface of the vertical walls of living rooms, such as providing inspection ports for inspection of air conditioner piping. Yes. In such a case, when the frame body that borders the wall opening is exposed to the outside, this is visually recognized by the viewer, and the appearance of the inspection port portion is impaired.

  In view of this, an inspection port device disclosed in Japanese Patent Application Laid-Open No. 2009-57711 has been proposed as an improvement in appearance due to the exposure of the frame. As shown in FIG. 25, the inspection port equipment a is fitted into the wall opening c so as to frame a wall opening c opened in a wall body (for example, a vertical wall of a building) b to form an inspection port d. A rectangular frame-like frame e and a cover plate f for closing the inspection port d are provided, and the frame e is made inconspicuous when the inspection port d is closed by the cover plate f. It was intended to improve the external appearance.

  More specifically, as shown in FIGS. 25 to 26, the frame body e is formed on the opening edge j of the peripheral wall portion h that covers the upper, lower, left, and right inner surfaces g, g, and g of the wall opening c. A wall surface abutting portion m that covers the wall surface k of the cover plate f is provided, and a lid receiving portion r that receives the rear surface portion q of the outer edge portion p of the lid plate f is provided at the edge n of the back of the peripheral wall portion h. The spherical clips u and u are formed to protrude at both end portions of the upper surface portion and the lower surface portion of the lid receiving portion r. The spherical clip u is formed by integrally forming a spherical head w having a larger diameter at the tip of the shaft portion v, and has an appropriate flexibility as a whole.

  Then, in a state in which the frame body e is fitted in the wall opening c, the surface k of the wall surface k and the wall surface contact portion m and the surface x of the lid receiving portion r are made into a sheet-like surface finishing material y such as a vinyl cloth. By covering with, the frame e is not exposed to the outside and visually recognized by the viewer, so that the appearance is good. The surface of the cover plate f was also covered with the surface finish y.

  The lid plate f is provided with a concave spherical hole clip c1 at a position corresponding to the spherical clip u provided on the frame e on both end sides of the upper part and the lower part of the back surface z. It was done. When the inspection port d is closed with the lid plate f, the lid plate f is fitted into the frame body e. By this fitting, the spherical clip u provided at the four corners of the lid receiving portion r and the spherical hole clip c1 are brought into a match state. Push the cover plate f further. As a result, the spherical clip u and the spherical hole clip c1 are engaged with each other in a concavo-convex fitting state, and finally, the finished surface a1 of the cover plate f is substantially flush with the finished wall surface d1 of the wall body b. Thus, the inspection port d can be closed with the cover plate f so that the state can be maintained.

  27 to 28 show another aspect of the inspection port equipment a disclosed in the publication, and spherical clips u, u having the same configuration as described above are provided at both ends of the upper side of the lid receiving portion r. And a hook flange portion e1 having an L-shaped cross section was provided on the lower side portion over the entire length thereof. A spherical hole clip c1 having the same configuration as described above is provided at a position corresponding to the spherical clip u in the back surface of the lid plate f, and the hook flange portion e1 and A hooking flange portion f1 that is locked in a hooking relationship and functions as a hinge is provided. When the inspection port d is closed with the cover plate f, the position of the cover plate f is maintained to be inclined and the hook flange portions e1 and f1 are locked to each other. Subsequently, the hook flange The lid plate f is pushed in with the locking part g1 between the parts as a fulcrum, and the spherical clip u and the spherical hole clip c1 are engaged with each other. Thereby, the inspection port d can be closed with the cover plate f, and the state can be maintained.

  When the inspection port device a having such a configuration is used, there is an advantage that the appearance due to the exposure of the frame body e can be improved. However, when the lid plate f in the closed state is removed, the frame body e and the lid as described above are used. There was a problem that the surface finish y covering the plate f was easily damaged. That is, when the inspection port d needs to be opened both in the inspection port equipment a shown in FIGS. 25 to 26 and in the inspection port equipment a shown in FIGS. When removing a certain cover plate f, for example, a flathead screwdriver or the like is inserted into the gap h1 (FIG. 26) between the frame body e and the cover plate f to pry it open, and the engagement between the spherical clip u and the spherical hole clip c1. The joint is released (in the case of FIGS. 25 to 26), or similarly, the engagement between the spherical clip u and the spherical hole clip c1 is released and the hook flange portion f1 on the cover plate f side is framed. It was made to extract from the hook flange part e1 by the side of the body e (in the case of FIGS. 27-28).

  However, when prying open in this way, a phenomenon has occurred in which the tip of the driver rubs the decorative surface of the surface finish material y with great force. This is because the height of the support portion at the lower end of the lid plate f is difficult to change, and thus a large force is required for prying. As a result, the surface finish material y was damaged by a flat-blade screwdriver or the like, and the appearance was easy to be damaged. For this reason, there is room for further improvement even when using the inspection port equipment disclosed in Patent Document 3.

In the closed state, the lid plate 7 abuts against the front surface 110 of the lid receiving piece 35 as shown in FIG. 14B (in this embodiment, a screw head as the interval adjusting projection 107). 107a abuts), the elastic rear protruding piece 92 is supported from below by the upper end 100 of the engaging upright piece 36, and the elastic engaging piece 96 is elastically attached to the rear surface portion 95 of the engaging upright piece 36. Is engaged. Thereby, the outer edge portion 86 under the lid plate 7 is attached to the lower portion 124 of the peripheral edge portion 116 of the inspection port 6. And the said attachment part 115 which consists of iron pieces is detachably hold | maintained by the magnet piece 123 provided in the front-end | tip part of the said operating rod 120 in a retraction state by engagement with the said stopper part in a magnetic adsorption state. Yes. In this state, as shown in FIG. 14B, the decorative front surface 82 of the lid plate 7 is substantially flush with the decorative wall surface 79. And in the state which this cover plate 7 closed the said inspection port 6, as shown to FIGS. 12-14, the said makeup | decoration outer peripheral surface 83 (FIG.14 (B)) of this cover plate 7 opposes this. A joint groove 85 of about 2 to 3 mm is formed between the decorative inner peripheral surface 81 and the entire inner peripheral surface of the inspection port 6.

  When it is necessary to remove the lid plate 7 in the closed state and open the inspection port 6, as shown by an arrow F in FIG. Press backwards as shown. This pressing is possible because the pressing margin width L (FIG. 14A) is formed as described above. Thereby, the engagement between the operating rod 120 and the stopper portion is released, and the operating rod 120 protrudes forward by the biasing action. This protrusion is performed while the magnet piece 123 provided at the tip of the operating rod 120 maintains a magnetic attraction state with the magnetic piece 115a as the iron piece.

  As shown in FIG. 15B, the forward protrusion is performed by appropriately bending and deforming the elastic rearward protruding piece 92 and the elastic engaging piece 96 of the elastic engagement member 89. At this time, a portion 92a (FIG. 17C) of the elastic rear protruding piece 92 supported by the upper end 100 of the engaging upright piece 36 functions as a hinge portion, and the front of the operating rod 120 The cover plate 7 rotates forward with the protrusion. Then, with the operating rod 120 protruding forward, the elastic rear protruding piece 92 is supported from below by the upper end 100 of the engaging upright piece 36, as shown in FIG. The upper outer edge portion 112 of the plate 7 protrudes forward from the decorative wall surface 79. In this projecting state, the outer edge portion 112 on the lid plate 7 is pulled forward to release the magnetic adsorption state between the attachment portion 115 and the operating rod 120, and then the elastic engagement member 89 and the engagement member are released. When the cover plate 7 is lifted obliquely upward as shown by an arrow F2 in FIG. 16 so as to release the engaged state with the mating piece 36, the elastic engagement member 89 is subjected to the elastic deformation with appropriate elastic deformation. The engagement upright piece 36 is separated. Thereby, the inspection port 6 can be opened.

  Thereafter, when the inspection port 6 is closed with the lid plate 7, as shown in FIG. 17A, first, the elastic rear protruding piece 92, the elastic engagement piece 96, and the fixing piece 90 are used. The lid plate 7 is tilted forward so that the upper end 127 is positioned forward of the lower end 129 so that the front side portion of the engagement upright piece 36 enters the engagement groove 126 with the lower end opened. As shown by an arrow F3 in FIG. 17A, the lid plate 7 is lowered obliquely downward. When entering in this way, the elastic engagement piece 96 is formed by bending the inclined guide piece 98 at the lower end of the hanging piece 102, so that the elastic rear protruding piece 92 is formed at the upper end 100 of the engagement upright piece 36. When the inclined guide piece 98 exhibits a guiding action when supported from below, and the elastic engagement member 89 is elastically deformed as appropriate, the engagement standing piece 36 is guided to the engagement groove 126 without difficulty. It will be possible. Thereafter, as shown by a one-dot chain line in FIG. 17A, the elastic rear protruding piece 92 is supported by the upper end 100 of the engaging upright piece 36, and is provided on the outer edge portion 112 on the lid plate 7. The attachment portion 115 that has been placed is brought into a magnetically attracted state with the magnet piece 123 at the tip of the operating rod 120 in the protruding state.

  In this state, when the outer edge portion 112 on the cover plate 7 is pushed rearward as indicated by an arrow F4 in FIG. 17A, the elastic rear protruding piece 92 is supported by the upper end 100 of the engaging upright piece 36. The portion 92a (FIG. 17C) formed functions as a hinge portion, and the lid plate 7 rotates backward as the operating rod 120 moves backward, and then the operating rod 120 moves to the stopper portion. As shown in FIG. 13, the lid plate 7 assumes a vertical state and closes the inspection port 6. At this time, as shown in FIG. 14B, the lid receiving piece 35 and the engaging upright piece 36 are disposed between the elastic engaging piece 96 and the fixed piece 90 of the elastic engaging member 89. From this state, the suspended piece 102 of the elastic engagement piece 96 is elastically in contact with the upper portion 101 of the rear surface portion 95 of the engagement standing piece 36. As a result, the end portion 130 of the screw head (space adjusting projection 107) 107a is brought into an elastic pressure contact state with the lid receiving piece 35, and the rear surface portion 87 of the outer edge portion 86 under the lid plate 7 is The lid receiving piece 35 is supported by the screw head 107a. Thus, when the lid plate 7 is in the vertical state and the inspection port 6 is in the closed state, the elastic engagement member 89 that has been elastically deformed is elastically restored, so that the elastic engagement piece 96 is in the engagement standing state. In this state, the rear surface portion 95 of the piece 36 is elastically engaged, whereby the elastic rearward protruding piece 92 is stably supported by the engaging upright piece 36.

  Thus, in the state where the inspection port 6 is closed with the lid plate 7, the inner surface covering piece 26 of the frame 5 is covered with the same surface finishing material 75a when covering the wall surface 70. Since the front surface 76 and the outer peripheral surface 77 of the lid plate 7 are covered with the same surface finish 75a that covers the wall surface 70, the frame 5 is not exposed to the outside in the closed state. In addition, the decorative front surface 82 and the decorative wall surface 79 are substantially flush with each other. For this reason, the entire structure except for the joint groove 85 is in a series of appearances, and in the joint groove 85, the opposite groove side surfaces 131 and 131 are both covered with the surface finish 75a. Even in the joint groove 85, only the surface finishing material 75a is visible, and the appearance of the joint groove 85 is good.

  The lid holding structure of the lid plate 7 is such that an attachment portion 115 provided on the rear surface portion 113 of the outer edge portion 112 on the lid plate 7 is provided on the upper portion 117 of the peripheral edge portion 116 of the inspection port 6. The holding unit 119 can be detachably held, and FIGS. 18 and 20 show other configurations. In both of these drawings, the outer edge portion 86 under the cover plate 7 is supported by using a U-shaped elastic engagement member 89 having the same structure as described above, as shown in FIG. The protruding piece 92 is supported from below by the upper end 100 of the engaging upright piece 36 having the same structure as described above.

  In the closed lid holding configuration shown in FIG. 18, the attachment portion 115 is configured by using, for example, a magnetic piece 115 a as an iron piece or a magnet piece, and the holding portion 119 is configured by the wall opening frame assembly. 21 is configured by using a magnet piece 119b fixed to the lower surface 136 (the upper portion 117) of the upper wooden base frame member 16 constituting the member 21 by screws or the like. The closed state of the lid plate 7 is maintained by magnetic attraction between the magnetic piece 115a and the magnet piece 119b. When removing the lid 7 that is closed by the magnetic adsorption from the inspection port 6, for example, as shown in FIGS. 18A and 18B, the upper surface 139 of the makeup outer peripheral surface 83 of the lid 7 and the makeup inner periphery. For example, a flat-blade screwdriver 138 or the like is inserted into the gap 141 between the upper surface 140 of the surface 81 and the cover plate 7 is pry open so as to tilt forward as shown in FIG. At the time of this opening, the cover plate 7 can move downward as indicated by an arrow F5 in FIG. 19A while being accompanied by elastic deformation of the U-shaped elastic engagement member 89. 6 can be prevented, and the decorative outer peripheral surface 83 of the cover plate 7 can be prevented from being damaged. More specifically, the upper surface 140 of the makeup inner peripheral surface 81 of the inspection port 6 and the upper surface 139 of the makeup outer peripheral surface 83 of the lid plate 7 are damaged by the tip of the minus driver 138 or the like during the opening. Can be prevented. By prying open like this, the engagement between the magnetic piece 115a and the magnet piece 119b is released as shown in FIGS. As a result, the cover plate 7 is tilted forward as shown in FIG. 19A. Therefore, the cover plate 7 is lifted obliquely by holding the outer edge portion 112 with the hand, and the elasticity is increased. The engagement state of the engagement member 89 and the engagement upright piece 36 can be released, and thereby the inspection port 6 can be opened.

  18-19, in the closed lid holding configuration, the attachment portion 115 is configured using one of hook-and-loop fasteners that can be hooked together, and the holding portion 119 is configured using the other, both The lid plate 7 can also be configured to be held in a closed state by the engaging action of the surface fastener. Even in this configuration, the lid plate 7 in the closed state can be removed by using a flat-blade screwdriver or the like without causing damage to the decorative surface.

  In the closed lid holding configuration shown in FIG. 20, the attachment portion 115 is configured using an elastic engagement tool 115 c, and the holding portion 119 is an upper portion 117 of the peripheral portion 116 of the inspection port 6. The upper inward projecting piece 61a is configured as described above. For example, as shown in FIG. 21 (A), the elastic engagement tool 115c is entirely formed by bending a spring material, for example, a stainless steel plate. Backward bending that protrudes rearward at a required portion (the lower end 146 in this embodiment) of the fixed piece 145 such as the lower end 146 of the fixed piece 145 fixed using the same type of fixed screw 143 as the fixed screw 97 The piece 147 is bent and the tip 149 is bent to form an upper inclined engagement piece 150 that is inclined upward toward the rear, and the upper end of the upper inclined engagement piece 150 is connected to the rear via the arc portion 152. And a mountain-shaped engaging portion 154 formed by bending downwardly inclined engaging pieces 153 that are inclined downward.

  When the inspection port 6 is closed, the downward inclined engagement piece 153 is brought into contact with the lower end 160 of the upper inward protruding piece 61a as shown in FIG. As shown by the arrow F6 in the figure, the outer edge portion 112 on the lid plate 7 is pushed backward. Thereby, when the circular arc portion 152 of the chevron engaging portion 154 gets over the lower end 160, the chevron engaging portion 154 supports the lower end 146 of the fixed piece 145 as shown by an arrow F7 in FIG. Then, the upper end portion (arc portion) 152 of the chevron engaging portion 154 rides over the lower end 160, and then the chevron engaging portion 154 shifts to elastic return.

  As a result of this transition, as shown in FIG. 20, the tip 157 of the spacing adjustment protrusion 156 as the screw head 155 of the fixed screw 143 in the screwed state contacts the front surface 142 of the front contact piece 49. Touch. When the cover plate 7 closes the inspection port 6, as shown in FIG. 20, the upper surface 159 of the intermediate portion in the length direction of the upper inclined engagement piece 150 protrudes inwardly from the upper side. The engaged state comes into contact with the lower end 160 of the piece 61a, whereby the closed state of the lid plate 7 is maintained.

  When removing the cover plate 7 in the closed state, for example, as shown in FIG. 23A, a gap between the upper surface 139 of the makeup outer peripheral surface 83 and the upper surface 140 of the makeup inner peripheral surface 81 of the cover plate 7 is used. A flathead screwdriver 138 or the like is inserted into 141, and as shown in FIG. 22 (B), the lid plate 7 is pry open so as to tilt forward. This pry opening can be performed without difficulty because the cover plate 7 can move downward by elastic deformation of the elastic engagement member 89 as shown by an arrow F8 in FIG. 22 (B). Damage to the decorative surface (the upper surface 139 and the like) due to the layer 75 can be avoided. At the time of the opening, the upper end portion (arc portion) 152 (FIG. 22C) of the mountain-shaped engagement portion 154 gets over the lower end 160 of the upper inward projecting piece 61a, so that the cover plate 7 is moved forward. It will fall to the state. Thereafter, when the lid plate 7 is lifted obliquely upward, the engagement state between the elastic engagement member 89 and the engagement upright piece 36 can be released, thereby removing the lid plate 7 and opening the inspection port 6. be able to.

  As another configuration for holding the outer edge portion 112 on the lid plate 7 in the closed state by the attachment portion 115 and the holding portion 119, an engagement by uneven fitting between the attachment portion and the holding portion is possible. It can also be performed by a combined action. Even when the lid plate 7 is held in the closed state by such an engaging action, the lid plate 7 can move downward by the elastic deformation of the elastic engagement member 89. This can be done without fear of damaging the cosmetic surface.
