Japanese Unexamined Patent Publication No. 2014-127136 Japanese Unexamined Patent Publication No. 2014-127137

Maintenance work for traffic signal lamps is performed in the installed state. Since all the electrical components of traffic signal lamps are housed in the case body, the lid is swung upward at the start of work to open the case, the open posture is maintained during work, and the lid is closed again after work. It is not preferable for the worker to keep the lid open with his arms during work, so it is not preferable from the viewpoint of workability. Therefore, instead of the stick, the worker himself supports the lid with the helmet worn on his head to support both hands. You may work freely.

Therefore, it seems that a signal lamp with a built-in movable part that keeps the lid in the open position (for example, a refill rod or a damper rod) should be manufactured, but it is not included in the required specifications as an essential part. It has not been built in from the viewpoint of manufacturing cost and assembly man-hours. This is not limited to the storage case structure of the traffic signal lamp, and is the same regardless of the form of the storage case in which the lid pivotally supported by the case body is swung upward to open and close. Therefore, it is convenient if there is a structure that can exert the same effect without adding moving parts.

The present invention is a storage case that opens and closes by swinging the lid pivotally supported on the case body upward, and the lid can be maintained in the open posture without providing a movable part that can keep the lid in the open posture. It was devised for the purpose of providing.

The first invention for solving the above problems is to open a lid pivotally supported by a lateral swing shaft provided on a case body from a closed position (hereinafter referred to as "closed position") (hereinafter referred to as "closed position"). It is an openable and closable storage case in which the vertical direction at the time of installation is determined by swinging upward to expose the opening (referred to as "open posture"), and the lid has the insertion position of the swing shaft. The case body has an elongated hole through which the swing shaft is inserted so as to be displaceable between a first position on the upper side and a second position on the lower side in the closed posture, and the case body has the insertion position in the first position. The lid can be swung between the closed position and the open position in the position state, and the insertion position can be displaced between the first position and the second position in the open position. It is a housing case having a main body shape and a rotational load support portion that receives a rotational load around the swing axis of the lid in a state where the insertion position is the second position in the open position.

According to the first invention, after the lid is opened, the relative position between the case body and the lid is displaced so that the insertion position of the swing shaft is changed from the first position to the second position while keeping the open position. , A part of the lid is supported by the rotational load support part of the case body. Therefore, even if the lid tries to swing in the closing direction due to its own weight, the rotational load around the swing shaft is received by the rotary load support portion, and the lid is maintained in the open posture. That is, it is possible to realize a storage case in which the lid can be maintained in the open posture without providing a movable part such as a refill bar.

In the second invention, the lid has the elongated hole in the upper portion of the lid, and the body shape makes the upper portion of the lid slidable inward of the case body in the open posture. The storage case of the first invention has a shape that allows the insertion position to be displaced from the first position to the second position in the open posture.

According to the second invention, the relative position between the case body and the lid can be changed, that is, the insertion position can be displaced by a simple operation of swinging the lid upward and sliding the upper end portion inward of the case body. it can.

In the third invention, the rotational load support portion can come into contact with the upper portion by setting the insertion position to the second position in the open posture, and suppresses the upward movement of the upper portion. This is the storage case of the first or second invention, which is a contact portion of the lid that receives a rotational load around the swing axis.

According to the third invention, the lid is kept in an open state by restricting the movement around the swing axis.

The fourth invention is the storage case of the third invention, wherein the rotational load support portion is configured as one part of the main body shape.

According to the fourth invention, since the rotational load support portion can be obtained by devising the shape of the case body, the manufacturing cost can be suppressed low.

A fifth invention is any one of the first to fourth inventions, wherein the first position is one end of the elongated hole whose insertion position is the first position due to the weight of the lid in the closed posture. It is a storage case of.

According to the fifth invention, in the closed posture, the insertion position naturally becomes the first position, so that workability can be improved.

The sixth invention is the storage case of any one of the first to fifth inventions, wherein the elongated hole is provided so that the longitudinal direction of the elongated hole is along the longitudinal direction of the lid portion.

According to the sixth invention, since the direction of the displacement operation of the insertion position is along the longitudinal direction of the lid, it is easy to intuitively understand the operation of changing the relative position between the case body and the lid, that is, the displacement operation of the insertion position. .. Therefore, the displacement operation can be learned immediately.

It is a state where it can be done.

5 and 8 are a front view, a rear view, a right side view, and a left side view of the terminal box 16, respectively.
FIG. 9 is a cross-sectional view taken along the line BB in FIG.

The terminal box 16 has a storage space 161 for the terminal block 20, a lid 162, and a connecting portion 163 for connecting the single light unit 12 in the case body 160, and the vertical direction at the time of installation is shown in FIGS. 1 and 5. It is decided that it will be in the vertical direction. The case body 160 and the lid 162 are each molded as a resin mold.

As shown in FIGS. 5 and 9, the accommodation space 161 is a bottomed space that opens in the front direction of the signal lamp 10. A back wiring hole 173 for inserting an external signal line 22 (see FIG. 2) is opened on the inner side surface on the back side of the accommodation space 161 (corresponding to the bottom of the bottomed space), and a grommet 164 for the wiring hole is attached. ing. Further, a side wiring hole 174 through which the relay cable harness 24 (see FIG. 2) is inserted is provided on the right side surface of the accommodation space 161 when facing the front. When the terminal box 16 and the single light unit 12 are connected, the side wiring hole 174 is connected to the harness insertion piping portion 147 (see FIGS. 3 and 4) of the connected single light unit 12, and the relay cable harness 24 is connected. The terminal box 16 can be pulled into the bottomed recess 141 of the single light unit 12.

The accommodation space 161 of the present embodiment is set to be smaller than the volume of the case body 160. Therefore, the rib 160b is appropriately provided on the back side to maintain the strength of the case body 160 itself (see FIGS. 6 and 9), while appropriately removing the light from the back side to reduce the weight.

As shown in FIGS. 5 and 9, the lid 162 is swingably connected to the upper end of the case body 160 by a swing shaft 165. Specifically, an elongated hole 166 is provided above the lid 162 along the longitudinal direction of the lid 162 (closed state with the lid 162 closed: vertical direction in the state of FIGS. 5 and 9). A swing shaft 165 provided in the left-right direction is inserted through the elongated hole 166 in the upper part on the front side of the case body 160 and is pivotally supported.

The lid 162 is locked in a closed state by a snap lock 167 fixed to the lower surface of the case body 160. When opening the lid 162, the snap lock 167 is removed, and the lower end of the lid 162 is swung up to open it.
A waterproof packing or a waterproof structure shall be provided between the case body 160 and the lid 162 as appropriate.

As shown in FIGS. 5 and 7, the connecting portion 163 also serves as a skeleton portion on the right side when facing the front of the case body 160, and the connecting bolt holes 150 of the single light unit 12 when connected upward and downward, respectively (FIG. 4). A connecting bolt hole 170 facing the above) is provided. Of course, a side wiring hole 174 is also opened in the accommodation space 161 facing the harness insertion piping portion 147.

In the present embodiment, the vertical dimension of the case main body 160 is set to be smaller than the vertical dimension of the single light unit 12, so that the lower end portion of the connecting portion 163 extends downward from the case main body 160. Although it is designed, when the vertical dimensions of the case body 160 and the single light unit 12 are matched, the extension portion may be omitted.

The connecting portion 163 is based on the plate portion 163a, and the outer periphery thereof and the boss portion of the connecting bolt hole 170 and the side wiring hole 174 are appropriately connected by ribs 163b. As a result, the case body 160 is ensured to have sufficient strength as a skeleton suitable for integrally molding as a resin molded product while reducing the weight.

The same applies to the left side portion of the case body 160 of the terminal box 16 with respect to the structure for ensuring the strength as well as the weight reduction. That is, as shown in FIG. 8, a support bolt hole 171 for inserting a support bolt for connecting the signal lamp 10 to a support or the like is provided on the left side surface of the terminal box 16 when facing the front. Based on the portion 160a, the outer circumference thereof and the boss portion of the support bolt hole 171 are connected by a rib 160b, so that sufficient strength as a skeleton is secured while reducing the weight.

Next, the opening / closing operation of the terminal box 16 will be described.
FIG. 10 is a state transition diagram for explaining an operation of opening the terminal box 16.
As shown in FIG. 10 (1), when the lid 162 is closed, the swing shaft 165 is inserted on one end side (upper side in the state of FIG. 10 (1)) of the elongated hole 166 in the longitudinal direction. .. This insertion position will be referred to as the "first position".

As shown in FIG. 10 (2), the snap lock 167 is unlocked, the lid 162 is held in the same engaged position, and the lid 162 is swung up so as to swing upward to open the lid 162, that is, the “open posture”. To.

Then, as shown in FIG. 10 (3), after the lid 162 is sufficiently swung up to open the posture, the swing shaft 165 is slid in the slot 166 to form the swing shaft 165 and the slot 166. When the lid 162 is moved so as to change the insertion position of the slot 166 to the other end side in the longitudinal direction of the elongated hole 166, the lid 162 can be locked in the open posture (swinged up state). The insertion position at this time is referred to as a "second position". The insertion position of the swing shaft 165 can be displaced between the first position and the second position in the closed posture.

The case body 160 of the present embodiment is provided with a recess diagonally below the swing shaft 165 (rear side when viewed from the front) so that the upper portion of the lid 162 can be pushed in from the front direction to the back direction. ing. This recess is called a rotational load support portion 168. The concave shape of the rotational load support portion 168 is set so that the lid 162 cannot be pushed in unless it is swung up to a predetermined open posture shown in FIG. 10 (2). The rotary load support portion 168 can come into contact with the upper portion of the lid 162 by setting the insertion position to the second position in the open posture, and suppresses the upward movement of the upper portion to prevent the swing shaft of the lid 162. It is a contact portion that receives a rotational load around 165.

When the lid 162 is opened and the lid 162 is slid inward of the case body so as to be pivotally supported at the second position, the pivotal support side end of the lid 162 (lower side in the state of FIG. 10 (3)). (End portion; upper portion for lid 162) fits into the recess of the rotational load support portion 168. Then, even if the worker releases his hand from the lid 162 and the lid 162 tries to close by its own weight, the rotational load acting around the swing shaft 165 is supported by the recess of the rotational load support portion 168. That is, the upper portion of the lid 162 is restrained from moving upward, and the lid 162 does not close.

That is, the worker does not need to keep supporting the lid 162 in the open posture with one hand while working, and can perform maintenance work such as electrical work and wiring work with both hands. When closing the lid 162, the work may be performed in the reverse order. In the closed posture, the insertion position is the first position due to the weight of the lid 162.

As described above, according to the present embodiment, the lid 162 is provided with an elongated hole 166 through which the swing shaft 165 is inserted so that the insertion position can be displaced between the first position and the second position in the closed posture. Then, the case body 160 allows the lid 162 to swing between the closed posture and the open posture with the insertion position set to the first position, and the insertion position is set to the first position and the second position in the open posture. It has a shape that allows it to be displaced between the two, and is further provided with a rotational load support portion 168 that receives a rotational load around the swing shaft 165 of the lid 162 in a state where the insertion position is the second position in the open position. It is composed. Therefore, it is a storage case that opens and closes by swinging the lid 162 pivotally supported by the case body 160 upward, and keeps the lid 162 in the open posture without providing a movable part capable of keeping the lid 162 in the open posture. It is possible to provide a storage case that can be used.
