Description

FIELD OF TECHNOLOGY

This utility model relates to a telecommunications equipment unit mounted on a support structure and provided with a handle.

BACKGROUND OF THE INVENTION

In the field of telecommunications, most of the equipment used is remote telecommunication equipment installed on various supporting structures, for example, on towers, walls or roofs. At the installation site, this remote equipment is often manually controlled to one degree or another. It can be carried by hand or lifted using a rope or chain, or some simple lifting device / equipment. To enable these manipulations at the installation and installation site of the remote equipment in its proper position, some type of handle, as a rule, attaches directly to the remote equipment. Typically, this type of remote equipment is subject to the ergonomic concept of “one person carry”, which indicates that it weighs less than 23 kg and that it can be carried by one person.

The type of remote equipment under consideration should be able to withstand external conditions for a period of 15 to 20 years, and the handle also. It must be able to withstand cold, heat, rain, snow, solar radiation, etc. without decomposition or wear, while fully maintaining its functionality. Thus, in accordance with the prior art, rather strong fixed handles, for example, made of aluminum, which were simply screwed to the top of the remote equipment, were still used. However, such a handle makes telecommunication equipment more bulky, and there is a risk that something could accidentally catch on the protruding handle. Also, when packing and transporting such remote telecommunication equipment, it should be taken into account that the protruding handle leads to more bulky packaging and additional volume due to the handle.

BRIEF DESCRIPTION OF USEFUL MODEL

The objective of the utility model is to obtain a block of telecommunication equipment, which can be mounted on a supporting structure and which is provided with an improved handle that makes telecommunication equipment less bulky and easier to handle and pack.

A utility model relates to a telecommunications equipment unit, mounted on a support structure and provided with a handle, the handle comprising an elongated handle adapted to be gripped by a human hand and a lifting device containing a recess located on the lower surface of the handle portion, this recess is configured to receive lifting equipment . The handle is foldable, and thus, when the handle is folded, the bottom surface of the handle is substantially flush or adjacent to the outer surface of the telecommunications equipment unit.

A folding handle can achieve many benefits. During transportation of a telecommunications equipment unit, the handle is folded and takes up much less space than the handle of the prior art. It also takes up less packaging space. Moreover, a folded handle located substantially flush with or adjacent to the outer surface of a telecommunications equipment unit is not at risk of engaging with anything with the same probability as a conventional fixed handle. Additionally, it also gives a more uniform visual appearance to the telecommunications equipment unit.

In accordance with one embodiment of a telecommunications equipment unit, the handle folds automatically. The handle may also be configured to take two positions, a first folded position and a second working position. When the handle is not in the working position, i.e. in a position where it can be easily grabbed by hand or used to connect to lifting equipment, the handle will automatically fold into its folded position. Therefore, there is no need, for example, to press the handle in order to fold / remove it.

In order to make the handle automatically foldable, the handle may preferably comprise at least one spring element operable to retract the handle of the handle from the second operating position to the first folded position. The use of a spring element for these purposes is convenient. The spring element may comprise any type of resilient or elastic element that can exert a pulling force and pull the handle toward the surface of the telecommunications equipment unit in order to fold the handle. Examples of suitable spring elements include a coil spring, a rubber band or their equivalents.

The handle may contain a pair of brackets attached to the connecting wall on the telecommunications equipment unit, a pair of links, each of which connects the bracket to the handle, and each link is pivotally attached to the bracket at the first hinged end of the link, and is movably attached to the handle using the second end link. Thus, by performing a handle comprising several prefabricated parts, much greater flexibility is achieved in order to make the handle foldable.

The handle may comprise a hollow interior, and the handle may be provided with spaced holes communicating with the hollow interior, and the further mentioned second end of the corresponding link is inserted into the corresponding hole. Moreover, the second end of the corresponding link may be able to slide into the said hollow inner part, so that during folding the handle, when the handle moves from the second working position to the first folded position, the corresponding link is gradually diverted to the hollow inner part of the handle. By giving the handle such a technical design, a folding handle is obtained, which is very thin when folded and does not affect the available volume inside the telecommunications equipment unit, since it is located completely on the outside of the unit, even when folded. Therefore, there is also no negative effect on the operation of a telecommunications equipment unit. Another advantage is that all movable elements are located inside the handle in the folded position, and they are thus protected during the normal operation of the telecommunications equipment unit, since the handle will be folded.

According to one embodiment, at least one spring element is located inside the hollow inner part of the handle, and the respective second ends of the links are provided with a spring support device for connecting to at least one spring element, and, further, at least one spring element functions with the ability to divert the corresponding link into the hollow interior. Thus, the spring element is also protected inside the handle. At least one spring element may be one spring element attached to the respective second ends of the links, or each link may have its own spring element, in which case such a spring element will also need to be secured in the hollow interior of the handle.

In accordance with one aspect of the present utility model, the links are configured as connecting rods, with each connecting rod provided with two laterally projecting pivot pins at its first pivot end, and two laterally extending connecting devices at its second end for movable connection to the handle. By performing the links as connecting rods, good durability is achieved.

Since the handle material must withstand harsh and changing external conditions for many years, examples of suitable materials are aluminum, fiberglass reinforced plastic or other synthetic materials, and the like. This applies in particular to the outer parts of the handle.

The aforementioned features and aspects of a telecommunications equipment unit, in accordance with the present utility model, can be combined in a variety of possible ways, providing further preferred embodiments.

Additional features and advantages of embodiments of the utility model will also become apparent from the following detailed description of embodiments.

DETAILED DESCRIPTION

FIG. 1 schematically depicts an embodiment of a unit 1 of telecommunication equipment mounted on a support structure in accordance with a utility model. The telecommunications equipment unit is provided with a handle 3, which is folding. By the term “folding” is meant that the handle can be lowered, or folded down, as shown in FIG. 1. The folded position will be the normal position of the handle when not in use, for example, to carry unit 1 of telecommunication equipment. The schematically shown telecommunication equipment unit may be any type of telecommunication equipment that needs to be moved or lifted, and which thus needs a suitable handle. Examples of such telecommunication equipment units 1 are remote telecommunication equipment units, for example: Remote Radio Unit (RRU), Remote Base Radio Station (RBS), Remote Digital Unit (OD), Access Points (WiFi), Mini communication devices installed on towers, and Radio unit (AIR) combined with the antenna, which are intended for installation on some type of support structure, such as a tower, wall, roof, etc. The telecommunications equipment unit is thus also provided with a mounting device (not shown) for mounting telecommunications equipment on a tower, wall, roof, etc., such as a structure with brackets and screws.

The handle of the telecommunication equipment unit 1 comprises an elongated handle 5 adapted to be gripped by a human hand and a lifting device, comprising a recess 7 located on the lower surface 35 of the handle 5. The recess is configured to receive lifting equipment, such as a rope or chain. As stated above, the handle is foldable, and when the handle is folded, the bottom surface 35 of the handle 5 is substantially flush with or adjacent to the outer surface 40 of the telecommunications equipment unit. This can also be seen in more detail in FIG. 9. Only a very narrow gap, of the order of 1-4 mm, is required between the handle and the said outer surface so that it would be more convenient for a person to place his fingers under the handle or grab the handle adjacent to the bottom surface 35 and pull the handle up.

The handle of the telecommunications equipment unit is configured to occupy two positions, a first folded position and a second working position. In FIG. 2 schematically shows the same telecommunication equipment unit 1 as in FIG. 1, but with the handle in the second operating position, which is the raised position, a position ready for use. In this position, there will be enough space between the handle 3 and the surface of the telecommunication equipment unit 1 to which the handle is attached in order to place a hand between the surface and the handle for gripping the handle and lifting the telecommunication equipment unit. There will also be enough space for attaching a rope or chain. From this position, the handle may be folded, and in one embodiment, configured to fold automatically to the folded position shown in FIG. 1, as soon as the lifting force is not exerted on the handle, which will be explained in detail below.

In the illustrated telecommunication equipment block of FIG. 1 and 2, the block is provided with only one handle, but naturally the block can also be provided with two or more handles, if required. This may be, for example, if the telecommunications equipment unit is very long or too heavy.

A handle 3, various objects of which are shown in more detail in FIG. 3-9, contains an elongated handle 5, the first and second links 13, 15, and the first and second brackets 9, 11. The links 13, 15 are connected to the handle 5 using brackets 9, 11. The brackets are used to connect the handle to the connecting wall 10 on a telecommunications equipment unit, as shown in FIG. 1, 2, 8 and 9, for example, with screws. The first end 13a of the first link 13 connects the first end 14 of the handle 5 to the bracket 9, and the first end 15a of the second link 15 connects the second end 16 of the handle to the second bracket 11. The first ends 13a, 15a of the links are pivotally connected to the respective brackets. The second end 13b of the first link 13 connects the first link to the first end 14 of the handle, and the second end 15b of the second link 15 connects the second link to the second end 16 of the handle.

The handle has a hollow interior 20, which can be a solid hollow interior, or can be divided into several sections of the hollow interior, see FIG. 5-7 and 8. Access to the hollow interior is provided by a hole 19, 21 at each end 14, 16 of the handle. Through these openings, the second ends 13b, 15b of the respective links 13, 15 can be inserted and the corresponding link can be diverted into the hollow interior 20 of the handle, thereby forcing the handle to fold as shown in FIG. 7 and 9. In order to make the handle automatically foldable, i.e. foldable as soon as the lifting force is not exerted on the handle, the retractable links are connected to the discharge spring element 30. This spring element may, for example, be a rubber belt, a helical spring, or any other suitable resilient or elastic element that will automatically pull the link inward hollow interior as soon as there is no lifting force exerting traction on the handle and spring element. Examples of various embodiments of the spring element are shown in FIG. 5 and 6. The spring element may be one element for both links 13, 15, or each link may have its own spring element, in which case the spring elements will be attached to a fixed support inside the handle.

The spring element 30 is attached to the links 13, 15 by means of a spring support device 31, 32 at the respective second ends 13b, 15b of the links. Additionally, these ends of the links must be made with connecting means so that they provide a reliable connection with the handle 5, which is strong enough to withstand the load when the telecommunication equipment unit 1 is lifted using the handle 3, and at the same time they must be made so that it is easy to slide inside the handle 5 when the spring element 30 pulls the links during folding of the handle. As an example, they can be provided with at least two laterally protruding connecting means 42, such as tabs, which are placed in the corresponding recesses 47 in the handle, just inside the holes 19, 21, and which additionally have a shape such that they could slide inwardly into the hollow interior of the handle 20.

As stated above, the first ends 13a, 15a of the links are pivotally connected to respective brackets. To perform the hinge function, the first ends 13a, 15a are provided with pivot pins 41, and the staples are provided with corresponding recesses 45 into which the pivot pins are placed. Alternative hinge or swivel designs may also be provided. Also in this case, it is important that the first ends 13a, 15a together provide a reliable connection with the brackets 9, 11, which is strong enough to withstand the load when the telecommunication equipment unit 1 is lifted using the handle 3, and at the same time they must be designed so that it is easy to turn when the handle is folded.

Links 13, 15 in the illustrated embodiment are made as continuous connecting rods. However, other types of links may be provided, such as square frame links or two-part links.

The handle preferably consists of two parts that come together after assembling various components, such as the spring element and the ends of the links inside the handle.

The utility model should not be construed as being limited by the described embodiments, it can be modified and modified in a variety of ways, which is clear to those skilled in the art without leaving the scope of the utility model defined in the attached utility model formula.
