Description

[0001] 1. Field of the Invention [0002] The present invention relates to an arm module for a building,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bar module coupled to a street lamp strut or a pole, and more particularly, to a bar module that is easy to install, easy to repair, and can easily control an angle of illumination of a street lamp or a cctv camera.

Generally, a streetlight refers to a lighting facility installed along the road or around the periphery of a facility for the safety and security of the street traffic, and it is suitable for a place such as a highway, a public road, a residence, Type is used. On the other hand, it is common that traffic information acquisition and security cctv cameras are installed in street lamps or electric poles in specific locations similar to streetlights. In the following description, a streetlight will be mainly described, but the term "light fixture " in the description means a fixture installed in a street lamp or a pole, such as a cctv camera, via a bar.

Usually, a street lamp is composed of a street lamp fixed vertically to an anchor in the ground, an arm band coupled or integrally formed with the upper part of the streetlight, and a luminaire (installation) coupled to the front end of the arm band. However, since the street light with the street light-bar-light luminaire is heavy and has a large outer shape and is substantially a-shaped (see FIG. 1A) in the coupled state, it is not easy to carry- There are many cases where they are assembled and installed in the field after they are manufactured and transported.

A portion consisting of a joint band, a support plate, and a bar, to which one end is assembled to a street lamp or a pole (hereinafter referred to as a support) and to which a fixture such as a cctv camera is mounted at the other end, Quot; bar module "

On the other hand, there is a need to install a streetlight (see Fig. 1A) or install a streetlight (see Fig. 1B) in a previously installed pole on the existing streetlight. In this case, the bar module is adopted.

Conventionally, a registration module 20-0383879 discloses a bar module in which a bar and a luminaire are coupled to a support by a metal bonding band convexly processed so that a bar end is inserted at the center thereof (see FIG. Registration No. 20-0345006 relates to a bar module in which a support and a lamp are fixedly coupled to a support plate having a surface contacting the support, and the support plate is wound around the support frame by a coupling band (refer to FIG. Japanese Patent Application Laid-open No. 10-1166213 discloses a lighting system comprising a first support plate installed on a pole or a streetlight and fixed to a streetlight by a coupling band, a lower support having a lower end hinged to a lower end of the first support, (Refer to FIG. 1E). When repairing the luminaire, it is necessary to unscrew the screw and turn the second support plate to lower the luminaire .

On the other hand, since the ordinary streetlight as shown in FIG. 1A is set at regular intervals in a certain position of the road, the position and the irradiation direction of the lamp are generally uniformly shaped. However, the bar module may be installed in street lamps or electric poles installed at regular positions and intervals like ordinary street lamps, but it is often installed in irregularly installed poles in winding roads or rural roads. In this case, the height at which the bar module is installed, the direction and the angle to be irradiated must vary in accordance with the environment in which the electric pole is installed, the number and position of electric wires passing through the electric pole (see FIG. FIG. 2 conceptually shows a situation in which the position where the streetlight light is irradiated and the position where the streetlight is to be irradiated (delivery) are offset.

However, the above-described conventional bar module is fixedly coupled to the support plate and the arm stand by welding, and the arm stand and the luminaire are also fixedly coupled by a fitting-bolt fastening method. Since the length of the arm and the angle of the lamp are determined, it is practically impossible to install the lamp at the position and angle where the light is irradiated so as to achieve the optimum effect in various environments.

In addition, since the bar module according to the prior art requires welding of related parts (supporting plate and bar) and then working with a hand tool (hand grinder) to clean the surface of the welding part, it takes a long time to work, Industrial dusts such as pulmonary diseases and musculoskeletal diseases for hand tool vibration frequently occurred in workers.

On the other hand, according to the related art, since the contact surface between the support plate and the arm rest is narrow, it is difficult to support the load of the arm rest and the lamp for a long time even if welding is performed. That is, as shown in FIG. 1D, it is practically impossible to allow only one arm to be coupled to the support plate. Therefore, as shown in FIG. 1E, it is a reality in the industry to secure an attachment force by placing an auxiliary arm below or above the main arm. The adoption of the main arm and the auxiliary arm in this way causes an increase in the material cost and the processing cost.

Also, since the lamp module according to the prior art has a luminaire integrally manufactured, two lamps must be operated at the same time, since one lamp must support the [lamp module] and the other lamp needs to fix the coupling band Reference). This is not only very difficult but also difficult to work on a pole with a lot of wires as shown in the right picture of Fig. 1B.

In addition, if the existing bar module is replaced due to a long life, or if the design is improved and replaced, disassembly and reinstallation are also very difficult tasks.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the accompanying drawings. It is to be understood, however, that the drawings are only illustrative of the content and scope of the technical idea of the present invention, and the technical scope of the present invention is not limited or changed. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the technical idea of the present invention based on these examples. It is also to be understood that when an element of a claim is referred to by reference to an element, it is for the purpose of illustration only and is not intended to limit the element.

Also, in the present invention, it will be explained that a luminaire and a streetlight are mainly described, but a fixture such as a cctv camera can be handled in the same manner in place of a luminaire.

As described above, the present invention is characterized in that it comprises a support plate 10, 50 fixed to the upper end of a support P such as a street lamp or an electric pole, a coupling band 42 for fixing the support plate 10, 50 to the support P, The invention relates to a bar module comprising a bar (20) coupled to a support plate, the bar module being characterized by the support plates (10, 50) and the bar (20) and their associated relationship.

The present invention is divided into the inventions relating to the 'integrated type' and the 'detachable type' bar module according to the structure and function of the support plates 10 and 50 and the connection relation between the support plates 10 and 50 and the bar 20. The 'integrated' and 'detachable' bar modules according to the present invention are relatively 'detachable' compared to the bar modules according to the prior art, .

(1) Integrated bar module

An example of the integrated type bar module according to the present invention is shown in FIG.

In the integrated bar module according to the present invention, the support plate 10 includes: a base portion 11 having one side abutting against the pillars P; and a base portion 11 formed on the other side of the base portion 11, Side support vanes 12 that are vertically spaced apart at corresponding intervals. The base portion 11 and the both side support vanes 12 may be integrally formed by a single metal plate or may be formed by bending a metal plate to form a U- Or by a method of welding or screwing the parts 11 (Fig. 3A).

The bar 20 is inserted between the two side support vanes 12 and is fixed while being rotated by an axis. To this end, a rotary shaft hole 12a is formed in the vicinity of the base of the side support vanes 12, And a support hole 12b is formed so as to face on a concentric circle at a predetermined distance. The support hole 12b may be a long hole formed on a concentric circle or a plurality of through holes.

In the integral type bar module according to the present invention, the bar 20 is provided with a rotation hole 21 corresponding to the rotation shaft hole in the vicinity of one end thereof and a support hole 12b corresponding to the rotation hole 21 at the predetermined distance A fixing hole 22 is formed. That is, when the bar 20 is inserted between the two side support vanes 12 and the rotation hole 21 near one end of the bar 20 is aligned with the rotation axis hole 12a of the support vane 12, The fixing holes 22 of the support vanes 12 are aligned with the support holes 12b of the support vanes 12.

When the one end of the bar 20 is inserted between the two side support vanes 12 to fix the bar 20 to the support plate 10 so as to be rotatable, the rotation shaft hole 12a of the support plate and the bar 20, A fixing hole 22 of the bar 20 and a predetermined supporting hole 12b of the supporting vane 12 for fixing the fixing bar 22 to the rotary support shaft 21, The minor axis 32 is inserted. At this time, the rotation support shaft 31 and the fixing shaft 32 are preferably bolts-nuts.

In the case of the integrated type bar module according to the present invention, as shown in FIG. 3B, when changing the angle (position) at which the street lamp should be irradiated, the following simple operation is performed. (1) When the support hole 12b of the support vane 12 is in the shape of a long hole formed on a concentric circle, the fixing shaft 32 is slightly loosened and the rod 20 is appropriately rotated around the rotation support shaft 31 And then fixing the fixing shaft 32 to fix the streetlight illumination angle. (2) When the support hole 12b of the support vane 12 is a plurality of through holes formed concentrically, the fixing shaft 32 is slightly loosened and disassembled, and then the bar 20 is rotated around the rotation support shaft 31 So that the lighting angle of the street lamp or the cctv camera can be adjusted in a simple manner in which the fixing hole 22 is aligned with the supporting hole 12b of the support vane 12 at the proper position and then the fixing shaft 32 is inserted and fixed .

As described above, according to the present invention, it is possible to adjust the viewing angle of a facility such as a luminaire 41 or a cctv camera (hereinafter, referred to as a ' luminaire ' Particularly in the case of the LED lamp (41), which has been applied recently, the light has a narrow diffusibility and only has a straight line, resulting in a lot of complaints after installation. At this time, it is possible to easily adjust the desired angle, thereby easily solving the problem.

Further, according to the related art, even when a worker goes up to the pillar P when the lamp (or the cctv camera) is replaced, his / her hand does not reach the lamp 41 (see the left side of Fig. 3C). However, according to the present invention, since the bar 20 is rotated downward to place the lamp 41 close to the body and then the bar 20 is rotated to the original position, You will be able to perform lamp replacement and repair work without a crane car.

In the bar module according to the present invention, it is preferable that the fixture such as the lamp 41 is detachably coupled to the bar 20. Accordingly, when the entirety of the lamp 41 is broken or when the conventional bulb-type lamp 41 is replaced with the LED lamp 41, it becomes very convenient to work.

When the bar module according to the present invention is installed, the fixtures such as the luminaire 41 are repaired or removed, or the angle is adjusted, the [bar module-fixture] is excessively downwardly rotated due to its weight, . At this time, it is preferable to provide the sag preventing means 12c at the lower part of the support vane 12 in order to prevent such over rotation. In the drawings and production examples, the bolt-type rods are inserted between the side support vanes 12, but the gap between the support vanes 12 may be narrowed.

On the other hand, it may be difficult to irradiate light at a desired position only by adjusting the irradiation angle of the lamp 41 (the fixed angle of the bar 20) according to the surrounding environment when the streetlight is installed. In order to cope with this situation, in the bar module according to the present invention, the bar 20 may have various lengths so that the bar 20 (or the cctv camera) ) (See Fig. 3d). That is, when the length of the bar 20 is longer or shorter, only the bar 20 can be replaced without replacing the entire bar, which is economical

As described above, the integrated bar module according to the present invention provides advantages in that it is very convenient in manufacturing / transporting and maintenance of the bar module compared to the conventional bar module. Also, according to the related art, the support plate 10 and the bar 20 are fixed at almost right angles to each other by welding even when they are installed in the field, so that even when two operators are installed, Due to its weight (see FIG. 2b) it was very difficult to secure the support plate 10 with the connecting band. However, in the integrated type bar module according to the present invention, after the support plate 10 is fixed with the connecting band in a state where the bar 20 is initially attached to the support plate 10 (see Fig. 3C), the bar 20 is rotated, The installation work can be performed much easier than in the prior art.

However, although the installation work is easier than the conventional technique, the whole of the bar module is lifted up at one time and fixed to the upper part of the column P, which is still a considerable difficulty.

The integrated bar module according to the present invention is advantageous in that it can control the angle (the angle of the bar 20) to be irradiated unlike the bar module according to the related art. - the lamp 41) is fixed and the lamp 41 can not be horizontally rotated according to the environmental condition.

The inventor of the present invention provides a 'removable' bar module in which an integrated bar module having such characteristics is improved.

(2) Removable bar module

FIG. 4A is a conceptual diagram showing a part of an example of the detachable type of the present invention, and FIG. 4B shows a mounting and demounting process of an example of the detachable type of the present invention. The reference numerals of the support plate 50 and the lower component parts thereof are represented differently from the integral type so as not to be confused.

The detachable bar module according to the present invention is characterized in that the support base 50 is divided into a first base portion 51 and a second base portion 52 which are detachable. That is, the support plate 50 includes a first base portion 51 having one side abutting against the support pillars P and a mounting base 51a for fixing the support bar 52a of the second base portion 52 on the other side, A supporting rod 52a fixed to the mounting base 51a of the first base 51 and a supporting rod 52a vertically installed at an upper portion of the supporting rod 52a at intervals corresponding to the cross- And a second base portion 52 having both side support vanes 52b.

The support base 51a may be in the form of a rod for interpolating all or a part of the lower end of the support rod 52a and may be in the form of an extrapolating rod. The lower end of the support rod 52a, And a catching jaw 51b for catching the escaping downward can be formed. The second base portion 52 is preferably manufactured by bending a metal plate on the upper portion of the metal support bar 52a and welding or screwing the two side support vanes 52b made into a C-shape. At this time, at least the lower portion of the support rod 52a may be a circular seal.

The structure of the bar 20 in the detachable bar module according to the present invention, the coupling relationship between the bar 20 and the two side support vanes 52b, the method of changing the street lamp irradiation angle, the method of replacing the lamp (cctv camera) And the length of the bar 20 are the same as those of the 'integrated type' bar module described above, so that further explanation and illustration are omitted.

The detachable bar module according to the present invention can be installed by a convenient method as follows (see FIG. 4B).

First, the worker lifts only the first base portion 51 and fixes the top of the pillar P using a connecting band. Since the first base portion 51 is a part of the entire bar module (about 30 to 40% by weight), it can be easily lifted and fixed easily. The second base portion 52, the bar 20, and the luminaire 41, which are the remainder (about 60 to 70% by weight) of the bar module, are lifted while the support bar 52a and the bar 20 are folded The holding rod 52a of the second base portion 52 is inserted into the holding base 51a of the first base portion 51 and then the bar 20 is rotated to unfold to fix the angle. In this way, the worker separates the bar module into two parts and works sequentially, so that even if two people work, it is possible to install the street lamp with much less effort than the conventional technique and with a considerably less effort with respect to the integrated bar module.

The support bar 52a of the second base portion 52 is inserted (or extrapolated) into the base 51a of the first base portion 51 or inserted (or extrapolated) into the base portion 51a of the first base portion 51, And is fixed with a bolt or the like. At this time, it is possible to conveniently change the irradiation position by horizontally rotating the supporting rod 52a (the bar 20 - the lamp unit 41) before fixing the supporting rod 52a to the mounting table 51a with bolts or the like 4c). To this end, the portion to be inserted (or extrapolated) of the support rod 52a is preferably a circular seal.
