Abstract

PURPOSE:To secure sufficient space for wiring even with a thin design guide lamp and prevent generation of resonance sound due to vibration outside of the guide lamp by introducing such a configuration that a transparent cover is mounted while rotated, and furnishing No.1 and No.2 elastic tabs in specified form. CONSTITUTION:In an arrangement concerned of a guide lamp in which a transparent cover 5 is mounted while rotated, and therein No.1 elastic tab (e) is furnished which is in a single piece installed on the cover 5 in such a condition as protruding from one edge of the cover 5 approx. in parallel with the cover surface and which is inserted and detained in/with an inside groove (g) of a lower framing 2 so as to work as the center of rotation when the cover 5 is mounted. Further No.2 elastic tab (a) is provided, which is in a single piece installed on the transparent cover 5 in such a condition as rising upright on the cover surface from the opposite side edge of the cover 5 and which is detained with a space (h) having a channel-form profile inside of the lower framing 2. This allows the space (h) to be effectively used as a wiring accommodating part, and besides it resonance of the cover 5 is suppressed owing to the resilience of the tabs (e, a).

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Field of Industrial Application The present invention relates to a light-transmitting cover mounted on an opening for illuminating the bottom surface of a guide light, and more particularly to a structure for mounting the light-transmitting cover.

(Conventional technology) Modern guide lights are becoming thinner in order to match the structure, and the space required to place the parts built into the guide light is decreasing. It is necessary to carefully distribute these built-in parts and wiring so that they do not cast shadows on the information display board.

FIGS. 6 and 7 show an example of this. To attach the light-transmitting cover used for the opening window for illuminating the lower surface of the guide light, tongue-like pieces a are elastically and integrally provided at appropriate positions on both sides of the light-transmitting cover 5.

By engaging the tongue-like piece a with the inner protrusion of the lower frame 2, the light-transmitting cover is attached. In this case, wiring spaces C for distributed arrangement are formed inside the lower frame 2.

However, in such a configuration, the wiring space is further reduced because the tongue a intersects the wiring space C-1 Also, because the tongue a closes the opening side of the wiring space C Assembling efficiency is reduced, as the work of passing the wires through the wiring space becomes troublesome. Further, in a state where the light-transmitting cover is installed on the lower frame body, the light-transmitting cover vibrates due to vibrations from outside the guide light while the guide light is in use, and resonance noise is generated.

(c) Issues to be solved by the invention The present invention was made in view of the above-mentioned problems. Unlike thin guide lights, sufficient space for wiring cannot be obtained, and only a wiring fixture is used. We aim to provide a guide light that allows the internal wiring of the guide light to be easily held in place even when there is no space for the guide light, and whose transparent cover with an opening on the bottom does not resonate with vibrations outside the guide light. It is something to do.

(d) Means for Solving the Problems In order to solve the above problems, the present invention provides a guide light in which a transparent cover is provided on the lower opening window of the lower frame of the guide light main body.
The light-transmitting cover is configured to be installed by rotating the light-transmitting cover, and is integrally provided with the light-transmitting cover in a state of protruding from one side of the light-transmitting cover substantially parallel to the cover surface, and is inserted into the inner groove of the lower frame body. A first elastic tongue-like piece that serves as a mouth during rotation when the transparent cover is attached, and a first elastic tongue-shaped piece that is integrally provided on the transparent cover in a state that stands up from the opposite side of the transparent cover with respect to the cover surface. and a second elastic tongue-like piece that engages with a U-shaped cross-sectional space inside the lower frame.

e) Operation The space surrounded by the light-transmitting cover for the lower opening and the lower frame and having a double-shaped cross section can be effectively used as a wiring storage section. Furthermore,
The elasticity of each tongue-like piece suppresses rattling of the light-transmitting cover and suppresses resonance of the light-transmitting cover.

(Embodiment) An embodiment of the present invention will be described below in detail with reference to FIGS. 1 to 5.

1 is the upper frame that constitutes the guide light body, 2 is the lower frame,
A guide light main body with openings on the front and rear surfaces is formed by connecting both frames with a connecting fitting (not shown).

3 +4 A removable side cover that becomes a part of the outer shell of the guide light body; 4 is a guidance display board made of glass or synthetic resin; It is attached by inserting it.

5 is a light-transmitting cover for the opening of the lower surface of the guide light body. At an appropriate position on one side of the outer edge (side) of the light-transmitting cover, a first elastic tongue-like piece e is placed in a state of protruding almost parallel to the cover surface (slightly curved upward) from this side. The tongue-like piece e is inserted into and engaged with a groove g having an opening toward the inside of the lower frame body 2. Also, the groove g of the lower frame body 2 is provided on the outer side of one side. A third elastic tongue piece d for partially closing the opening of the U-shaped space other than g is integrally formed with the light-transmitting cover 5.Furthermore, a third elastic tongue-like piece d is formed integrally with the light-transmitting cover 5 on one side outside the light-transmitting cover 5. A second elastic tongue-like piece a is integrally provided on the outer edge (side) opposite to the edge so as to stand up from this side with respect to the cover surface.The tongue-like piece a is attached to the lower frame. It is engaged with an inner protrusion of the body 2. This inner protrusion defines a U-shaped space.

The elasticity of the first and second elastic tongues e and a is such that when the translucent cover 5 is attached to the lower frame 2 and the inwardly protruding portion thereof is protruded, a pressing force is constantly generated at the contact portion of the tongues a. To prevent the translucent cover 5 from vibrating and generating resonance sound.

Reference numeral 7 denotes a wiring cord similar to a guide light, which is inserted and held in a U-shaped space in the lower frame 2 whose opening is closed by a third elastic tongue piece d. When performing wiring work after attaching the transparent cover 5 (after completing the frame-related assembly), the wire coat after wiring is attached to the top sloped part of the tip l of the third elastic tongue piece d (as shown in Fig. 2). ) into the empty space. Since this U-shaped space is not crossed by any tongue-like pieces, it can be fully utilized as a space for wiring.

Next, to explain how to attach the light-transmitting cover 5, after inserting the first elastic tongue-like piece e of the light-transmitting cover 5 into the groove g inside the lower frame 2, the first elastic tongue-like piece e side is the center of rotation. As a result, the tip of the second elastic tongue a rotates to a position where it passes the tip of the inner protrusion of the lower frame body.

g) Effects of the Invention According to the present invention, a sufficient space for wiring can be secured even in a thin guide light, and the wiring can be laid out so as not to cast a shadow on the guide surface water roots. Furthermore, the transparent cover can be easily attached, and the troublesome work of wiring inside the guide light can be eliminated. Further, since parts for fixing the wiring inside the guide light are not used, there are advantages such as being able to reduce the space required for the wiring and expanding the range of materials that can be selected for the lower frame. Furthermore, generation of resonance noise due to vibrations outside the guide light can be prevented.
