This application is based upon and claims the benefit of the priority of Japanese patent application No. 2007-307509, filed on Nov. 28, 2007, the disclosure of which is incorporated herein in its entirety by reference thereto.
The present invention relates to an installation structure of a communication equipment and an installation method of the equipment, and particularly relates to an installation structure of an outdoor communication equipment and an installation method of the equipment installed at a place to be difficult to install such as a high elevation place.
A rapid development of the communication business in these days requires a necessity to install a lot of communication equipments at narrow outdoor places, on the top of a pylon tower, for example. Therefore, a simple and reliable installation structure and installation method of the communication equipment is required to install the communication equipment in such a narrow area.
When installing the communication equipment on a pylon or wall at a high elevation, a worker has to install the communication equipment with holding the communication equipment due to its narrow working space. As a result, the installation work becomes insecure and it may cause a breakage of the equipment.
A structure of a communication equipment is disclosed in Patent Document 1, which has a main body and a radiator and these parts can be combined by a guide pin and a handle easily.
The entire disclosure of Patent Documents 1 is incorporated herein by reference thereto.
As for a prior art communication equipment used outdoors a structural component for installation and a component (handle) for transportation or carriage are different and separated. Although a handle of the communication equipment is used at the first stage of the installation work of the equipment, it is not necessary after that, and therefore it should be deleted considering the installation work at a narrow area such as a top of the pylon. However, the handle itself is a necessary component for handling efficiency and cannot be deleted.
Until now there is a problem that the installation work of the communication equipment in a narrow space causes much load for a worker because the worker has to hold the communication equipment during the installation work and sometimes causes a breakage of the equipment, and this problem is not solved yet.
It is an object of the present invention to provide an installation structure and an installation method of a communication equipment to reduce a number of the components of the equipment and make the installation work easy.
According to a first aspect of the present invention, there is provided an installation structure of a communication equipment, e.g., to be installed outdoors. A handle for carrying the communication equipment also serves as a fixation component of the communication equipment.
The handle for carrying the communication equipment preferably comprises a hole for a fixation screw at a position corresponding to a screw fixation portion provided on a fixation mount to fix the communication equipment.
The communication equipment preferably comprises an inclined shape portion formed at a part of the bottom surface of the communication equipment to keep the communication equipment in a forward-inclined position temporarily when the communication equipment is set on the fixation mount preparatory to installation.
A profile of the inclined shape portion of the communication equipment is preferably linear or curved.
According to a second aspect of the present invention, there is provided a communication equipment to be installed outdoors. A handle for carrying the communication equipment also serves as a fixation component of the communication equipment.
The handle for carrying the communication equipment preferably comprises a hole for a fixation screw at a position corresponding to the screw fixation portion provided on a fixation mount to fix the communication equipment.
The communication equipment preferably comprises an inclined shape portion formed at a part of the bottom surface of the communication equipment to keep the communication equipment in a forward-inclined position temporarily when the communication equipment is set on the fixation mount preparatory to installation.
A profile of the inclined shape portion of the communication equipment is preferably linear or curved.
According to a third aspect of the present invention, there is provided a method for installation of a communication equipment, e.g., to be installed outdoors. The method comprises: providing an inclined shape portion formed at a part of the bottom surface of the communication equipment; and keeping the communication equipment in a forward-inclined position temporarily with the assistance of the inclined shape portion when the communication equipment is set on a fixation mount to fix the communication equipment preparatory to installation.
The meritorious effects of the present invention are summarized as follows. A first effect of the present invention is to reduce a number of components of the equipment. The reason is that the handle has a function for carrying the communication equipment and a function to fix the communication equipment on the fixation mount.
A second effect of the present invention is to make the installation work easy. The reason is that an installation worker can install the communication equipment without holding the equipment temporarily because the equipment can be inclined to the fixation mount stably with the assistance of the inclined shape portion formed at a part of the bottom surface of the communication equipment as a contact portion with the fixation mount of the equipment.
According to an aspect of the present invention, a handle of a communication equipment to be installed, e.g., at the outdoors, also serves as a fixation component of the communication equipment and the communication equipment can be fixed on a fixation mount of the equipment by the fixation component. A screw fixation such as a screw bolt may be used as a fixation means. In addition, a part of the bottom surface of the communication equipment has an inclined shape and therefore the communication equipment can be set stably (pre-installation state) in a forward-inclined position on the fixation mount temporarily. As a result, the workability of the installation work can be improved. A purpose of the inclined shape portion is to make the communication equipment easy to incline forward. Thus a cross section of the inclined shape portion can be linear, or arc curved to reduce a friction during a pushing step of the equipment. However, a friction resistance enough to keep the forward-inclined position of the communication equipment during the pre-installation state is necessary.
The installation structure of the present invention can be applied to a new communication equipment to install on an already existing fixation mount and applied to a new set of a communication equipment having a fixation handle and a fixation mount corresponding to the fixation handle of the communication equipment.
As shown in
The handles 2 can be formed in one piece with the communication equipment 1 at both sides of the communication equipment 1 or can be attached as a separate component. The handles 2 are used for carriage and installation work of the communication equipment 1 and protruding from both sides of the equipment 1, and formed U-shaped or rectangular shape for easy gripping. As shown in
The communication equipment 1 is installed on the fixation mount 3 in a vertical posture, by being moved in a direction of white arrow in
When installing the communication equipment 1 on the fixation mount 3, once the equipment 1 is inclined forward by setting the inclined shape portion 13 on the bottom portion 4 of the fixation mount 3, the handle 2 of the communication equipment 1 comes into contact with a seating plate 3a of the fixation mount 3 and the communication equipment 1 is stabilized in its forward-inclined posture (or position); pre-installation state as shown in
Then the communication equipment 1 is fixed on the fixation mount 3 by screwing the fastening bolts 6 in the screw fixation portions 9 of the keeping plate 3a through the fixation (screw) holes 10 of the handle 2 as shown in
It should be noted that other objects, features and aspects of the present invention will become apparent in the entire disclosure and that modifications may be done without departing the gist and scope of the present invention as disclosed herein and claimed as appended herewith. Also it should be noted that any combination of the disclosed and/or claimed elements, matters and/or items may fall under the modification aforementioned.
