Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a door scope that allows indoor light to pass to the outside of the room by being attached to a door that is not provided with a window such as a toilet.
[0002]
[Prior art]
In conventional doors that do not have windows, such as toilets, as a means of indicating whether the room is in use, red or the like near the handle on the outside of the room when a lock consisting of a thumb turn etc. is applied from inside the room However, it is difficult to see the display at night or in a dark place, which is inconvenient.
[0003]
In addition, there is a light bulb attached near the switch button of the light, and when the room is turned on, the light bulb is also turned on at the same time. It can be seen whether the room is lit at the place, but the structure is slightly complicated and it is not easy to understand at first glance because it does not directly convey the interior of the room to the outside. In such a case, there was a problem that the lighting in the room would not be understood.
[0004]
Therefore, our company was formed through a part of the door in Japanese Patent Application No. 9-362580 so that the indoor lighting state can be directly seen with a simple structure without performing wiring work or the like. It has been proposed that a door scope made of a highly translucent material is fitted into the opening to transmit light on the indoor side to the outdoor side.
[0005]
As a form of the door scope, as shown in FIG. 7 (A), the male screw 53a formed at the tip of the main body 52a inserted from one side of the door is formed on the lid 54a inserted from the opposite side. Proposed to be screwed into the female screw 55a or to be fitted by fitting the tip of the shaft 53b of the main body 52b into the fitting hole 55b of the lid 54b as shown in FIG. 7B. Has been.
[0006]
[Problems to be solved by the invention]
However, the door scope 51a shown in FIG. 7A is expensive to manufacture because the male screw 53a and the female screw 55a must be formed on the main body 52a and the lid 54a, respectively, and the mounting is troublesome. In the case of the door scope 51b of FIG. 7B, the inner diameter of the fitting hole 55b is usually made slightly larger than the shaft portion 53b in consideration of dimensional errors during manufacture and workability during installation. However, the main body 52b and the lid 54b are not in close contact with each other, and there is a problem that wobbling occurs after mounting.
[0007]
[Means for Solving the Problems]
Accordingly, the present invention is a door scope that is fitted into an opening formed through a part of a door, and is composed of a main body and a lid body each formed of a light-transmitting material and having a rib portion at one end. A groove is provided in the vicinity of the tip of the shaft portion extending in the tip direction from the rib portion, and an O-ring made of an elastic body is fitted in the groove, and the shaft portion is continuous with the rib portion of the lid body. Then, when inserted into the formed cylindrical portion, it is tightly fixed to the inner wall of the cylindrical portion by an O-ring.
[0008]
According to the present invention, since light is transmitted through the door scope having translucency inside the door, there is little loss of light amount due to diffusion and absorption of light in the middle of the path, and light is sufficiently transmitted. Even if the opening is small, light is transmitted from the indoor side of the door having a thickness to the outdoor side, and high-luminance light can be visually recognized from any angle on the outdoor side. Therefore, it can be confirmed from outside the room at night or in the dark that the room is lit in a door without a window such as a toilet.
[0009]
The door scope of the present invention can be obtained by inserting the main body from one side of the opening provided in the door and the lid body from the opposite side, and inserting the shaft portion of the main body into the cylindrical portion of the lid body. It can be easily inserted by elasticity, and the O-ring is in close contact with the inner wall of the cylinder part by simply inserting the shaft part to the position where each rib part of the main body and lid touches both sides of the door and closes the opening. And the lid are fixed.
[0010]
Moreover, if the O-ring is formed of a transparent body, there is no portion where light is shielded in the door scope, and a large amount of light can be transmitted.
[0011]
Furthermore, if at least one of the main body and the rib portion of the lid is made into a lens, the brightness is improved by condensing, and the light can be easily seen.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
[0013]
1 to 3 show an example of an embodiment of the present invention, and a door scope 2 of the present invention is attached to a door 1 that is not provided with a window, such as a toilet.
[0014]
The door scope 2 is fitted at an appropriate location of the door 1, for example, at a position where it can be easily seen, such as above the handle 3 as shown in FIG. 1, and is composed of a main body 21 and a lid 27 as shown in FIG. It is made of a highly translucent material such as hard resin or quartz glass forming a fiberscope. And, the main body 21 inserted from one side of the opening 10 formed through the door 1, for example, the indoor side 11, has a shaft portion 23 extending from the rib portion 22 toward the tip, and near the tip of the shaft portion 23. A groove 24 is provided over the entire circumference, and an O-ring 26 made of a synthetic resin having elasticity such as a transparent elastic body, for example, a soft polyamide resin, is fitted into the groove 24.
[0015]
Further, the lid 27 inserted from the opposite side of the main body 21, for example, from the outdoor side 12, has a cylindrical portion 29 formed continuously to the rib portion 28, and the inner diameter of the cylindrical portion 29 is that of the shaft portion 23 of the main body 21. It is formed slightly larger than the diameter.
[0016]
The main body 21 and the rib portions 22 and 28 of the lid body 27 which are both ends of the door scope 2 are formed by lenses, respectively, so that light is collected and easily visible.
[0017]
Note that the O-ring 26 swells more than the shaft portion 23 when fitted into the groove 24 and has the same diameter as or slightly larger than the inner diameter of the cylindrical portion 29 of the lid 27. The depth and dimensions of the O-ring 26 are determined. Further, the O-ring 26 may be made of a normal silicon rubber that is not transparent.
[0018]
When the door scope 2 is attached to the door 1, as shown in FIG. 3, for example, the main body 21 is connected from the indoor side 11 to the outdoor side 12 in the opening 10 having a diameter of about 15 to 20 mm provided in the door 1. Then, the lid bodies 27 are inserted, and the shaft portion 23 is inserted into the cylindrical portion 29. At this time, the O-ring 26 attached in the vicinity of the tip of the shaft portion 23 slides in the cylindrical portion 29, and the rib portions 22 and 28 of both the main body 21 and the lid body 27 are respectively placed on the surfaces 13 and 14 of the door 1. When the O-ring 26 is stopped when it is inserted to the contact position, the O-ring 26 comes into close contact with the inner wall of the cylindrical portion 29 by its restoring force, and the shaft portion 23 is fixed. Therefore, since it can fix in arbitrary positions, the length of the door scope 2 can be set arbitrarily and it can use for the door 1 of various thickness.
[0019]
Normally, the opening 10 is formed in accordance with the outer diameter of the cylindrical portion 29 of the lid body 27. Therefore, the base end portion of the shaft portion 23 of the main body 21 is prevented so that the central axis does not move when the main body 21 is inserted. It is preferable to form the protrusions 25 at the opposite positions. Alternatively, without providing the projections 25, 25, the end portion on the indoor side 11 of the opening 10 is matched with the outer diameter of the shaft portion 23 of the main body 21, the diameter is increased from the middle, and the end portion of the outdoor side 12 is connected to the lid body 27. You may form according to the outer diameter of the cylinder part 29. FIG.
[0020]
Through the door scope 2 fitted in the opening 10 as described above, light can be visually recognized from the indoor side 11 to the outdoor side 12 or vice versa.
[0021]
FIGS. 4 to 6 show different embodiments of the present invention, and show a door scope 4 of the type attached to the seat 5 of the door 1.
[0022]
A handle 3 is attached to the upper portion of the seat 5, and a door scope 4 is fitted to the lower portion of the handle 3. The door 1 is provided with a hollow portion 20 for installing the internal structure of the lock or penetrating the support shaft of the handle 3, and the door scope 4 has an indoor side as shown in FIG. 11 and the outdoor side 12 are fitted so as to close the openings 50, 50 penetrating the seats 5, 5. Thus, the light can be visually recognized through the door scope 4 from the indoor side 11 to the outdoor side 12 or in the opposite direction.
[0023]
This door scope 4 is made of a highly transparent hard resin, similar to the door scope 2, and comprises a main body 6 and a lid body 7 as shown in FIG. It is formed by a lens.
[0024]
An annular groove 62, a stepped portion 63, and an inclined portion 64 are successively formed between the rib portion 61 and the shaft portion 65 of the main body 6 in this order from the base end side. When the body 6 is inserted through the opening 50 of the seat 5, the main body 6 is inserted along the inclined portion 64, and the end edge of the opening 50 and the groove portion 62 are fitted together so that the main body 6 is fixed. . For this reason, the axial length of the groove 62 is substantially the same as the thickness of the seat 5, and the stepped portion 63 is formed to have a slightly larger diameter than the opening 50 of the seat 5.
[0025]
In addition, the lid body 7 is formed with a cylindrical portion 75 into which the shaft portion 65 of the main body 6 is inserted in succession to the rib portion 71, and in turn between the rib portion 71 and the cylindrical portion 75. A groove portion 72, a step portion 73, and an inclined portion 74 are formed. Like the main body 6, the axial direction of the groove portion 72 is substantially the same as the thickness of the seat 5, and the lid body 7 is inserted into the opening 50 of the seat 5. Sometimes, it is inserted along the inclined portion 74 and is fixed by fitting the edge of the opening 50 and the groove 72.
[0026]
Further, a groove 66 is provided around the tip of the main body 6, and an O-ring 67 made of an elastic body is fitted into the groove 66, and the main body 6 and the lid body 7 of the door scope 4 are connected. The joining method is the same as in the above embodiment.
[0027]
In both the above-described embodiments, either the main body 21, 6 or the lid body 27, 7 may be used as the indoor side 11 or the outdoor side 12.
[0028]
Further, even if the rib portions 22, 28, 61, 71 of both the main bodies 21, 6 and the lid bodies 27, 7 are not lenses, even if only one of them, for example, only the outdoor side 12 is a lens, the light collecting effect is obtained. Obtainable.
[0029]
Furthermore, if the rib part located in the outdoor side 12 is made into a transparent body or a lens with a color such as red or green, for example, it is clearly distinguished from the surrounding lights and can be easily recognized from a distance.
[0030]
【The invention's effect】
According to the present invention, since light is transmitted through the door, there is little loss of light amount due to light absorption or the like, and light can be transmitted sufficiently. Therefore, it is possible to easily recognize from outside the room whether or not the room partitioned by the door without a window is lit without requiring electrical wiring or the like, even in a dark place. Moreover, since it is impossible to see through only light, privacy can be protected.
[0031]
The door scope of the present invention is simple in structure and low in manufacturing cost, and can be attached and detached easily because it is fixed tightly just by inserting the main body into the lid. Further, since the O-ring presses against the inner wall of the cylinder portion and is fixed at an arbitrary position, the door scope can be made to have an arbitrary length steplessly and can be used for doors of various thicknesses. .
[0032]
In addition, if the existing door is fitted with a small opening or is replaced with a seat with a door scope fitted, the door can be easily used for any door without impairing the design and performance of the door.
[0033]
If the O-ring is a transparent body, the loss of the amount of light transmitted through the door scope can be reduced, and the visibility of light is further increased.
[0034]
Furthermore, if at least one of the door scopes is a lens, the light is easily collected by being condensed.
