Abstract
Description
- The present invention relates to a hinge device for the door of a switchboard enclosure.
- Switchboard enclosures comprise a rear box fixable to a vertical wall and capable of containing a plurality of electrical switches. Attached to the box is a front cover having one or more one or more openings for access to the control levers or pushbuttons of the electrical switches housed in the box. Along a vertical side of the box there are fixed two hinges forming pintles on which a door is rotatably mounted for closing the front of the enclosure.
- A general object of the present invention is to provide a hinge device capable of making the steps of assembling and disassembling the door of a switchboard enclosure safer and easier.
- A particular object of the invention is to provide a hinge device that allows an operator to assemble and disassemble a door in two phases, with an intermediate assembling or disassembling phase in which the door is secured to the enclosure provisionally but steadily enough to prevent the door from accidentally falling while the operator is completing the locking or unlocking of the door.
- These and other objects and advantages, which will be understood more fully below, are achieved, in accordance with the present invention, by a hinge device having the features defined in claim 1. According to another aspect of the invention, there is provided a door for a switchboard enclosure as defined in
claim 15. Preferred embodiments of the invention are defined in the dependent claims. - The features and advantages of the invention will emerge from the detailed description of an example of embodiment thereof, with reference to the accompanying drawings, provided by way of a non-limiting illustration, in which:
- figures 1 to 5 are perspective views showing the assembling steps of a hinge device according to the invention and a door on a switchboard enclosure;
- figure 6 is an exploded perspective view showing the front side of the hinge device and a fastening screw;
- figure 7 is a perspective view showing the rear side of the hinge device of Figure 6; and
- figures 8 and 9 a partial cross sectional views of the enclosure where a hinge is fitted.
- With reference to the drawings,
numeral 10 indicates overall one of the two hinge devices fixable along a side of afront cover 30 of a switchboard enclosure for rotatably mounting adoor 40. Thecover 30 is removably fixable by means ofscrew 50 to a rear box 34 (shown partially in figures 8 and 9) of the enclosure. Thecover 30 typically has anopening 31 in which there are locatedrecessed panels 60 allowing access to the controls of the electrical switches (not shown) housed in the enclosure. - Throughout the description and the claims which follow, terms indicating positions and orientations, such as "front", "rear", "horizontal" and "vertical", must be understood from the view point of a person standing in the front of an electric switchboard mounted on a vertical wall.
- Each hinge device 10 (only one is shown in the drawings) comprises a
body 11 of moulded plastic material forming abush portion 12 rearwardly projecting with an inner cylindrical non-threadedpassage 13 that passes through thebody 11 from side to side in the front-rear direction. On its outside, thebush portion 12 forms a pair of angularly spaced L-shapedradial recesses 14 intended to cooperate with a respective pair of formations 32 (figure 1) radially projecting in a horizontal throughbore 33 of thecover 30. Thehinge device 10 is coupled with thecover 30 by fitting thebush portion 12 in thebore 33, as indicated schematically by arrows A and B in figure 1. Therecesses 14 andprojections 32 provide a bayonet coupling mechanism that allows to fix thehinge device 10 to thecover 30 quickly and removably. - Each
hinge device 10 has two vertically alignedpintles door 40 is rotatably mounted. One of the pintles, indicated 15, is a fixed pintle or pin formed integrally with thebody 11, whereas theother pintle 16 is a mobile element formed separately from the body 11 (figure 6). Themobile pintle 16 comprises avertical pin portion 17 and alocking lever 18 perpendicular to thepin 17. Thepintle 16 is slidingly accommodated in thebody 11 along a vertical axis x aligned with the fixedpintle 15. - The
mobile pintle 16 is inserted in a vertical guidingchannel 19 formed by the body 11 (figure 6) and aligned with the axis x and a throughbore 20 obtained in aside wall 21 of thebody 11. Thepin 17 is inserted in snap manner in theguide 19, elastically forcing atooth 22 that serves to hold thepin 17 along theguide 19. After insertion, themobile pintle 16 is brought in a retracted position in which theend 17a of thepin 17 does not protrude out of the bore 20 (figure 2). This position is determined by the abutment of theother end 17b of the pin against astop 23. - The
door 40 is preliminarily coupled with the fixed pintle of each hinge device by a snap coupling (figure 3, arrow C) obtained by fitting thefixed pintle 15 in afork formation 41 of the door. A preliminarily assembled condition is so achieved (figure 4), in which abore 42 of the door is axially adjacent and aligned with thebore 20 of each hinge and with thepin 17 retracted. By acting manually on thelever 18, themobile pintles 16 are then forced to slide in the vertical direction indicated by arrow D in figure 4, thereby bringing thepins 17 in an extended position where they pass through both of thealigned bores mobile pintle 16 with respect to thedoor 40 and thebody 11 of the hinge are prevented by rotating thelever 18 about the axis x until the lever is locked between a pair of vertically spaced and elastically openable locking teeth 25 (only one of which is visible in the drawings). In this position (figure 5), theteeth 25 hold thelever 18 so as to prevent thepintle 16 from sliding in the direction of axis x and thereby the door from accidentally coming off. The door is so secured steadily to each hinge device at two distinct points. - In order to assemble a door, two hinge devices must first be mounted on the
enclosure cover 30. Then thedoor 40 is preliminarily coupled with each hinge device by making theforks 41 snap-engage thefixed pintles 15. It should be noted that in this condition (as shown in figure 4) the door is suspended to the enclosure but needs to be secured more steadily, because if it were opened by rotating it more than 180° degrees from its closed position, theforks 41 would be forcefully brought apart from one another and would come off thefixed pintles 15. However, the provisionally secured condition of figure 4 allows the operator to complete closing themobile pintles 16 safely enough for himself and the door, which will not fall unless it is opened too much, as said. The same safety is attained upon disassembling the door. After unlocking themobile pintles 16 by making thelevers 18 first rotate free of thelocking teeth 25 and then withdrawing theends 17a of the pins from thebores 42 of the door, the operator has both of his hands free to grab the door and remove it in snap manner of thefixed pintles 15. - Referring finally to figures 8 and 9, the
horizontal bore 33 of thecover 30 is axially aligned with the threadedbore 35 of therear box 34. Ascrew 50 for fastening thecover 30 onto the box 34 (figure 9) is fitted through thecylindrical passage 13 of the hinge and thenon-threaded bore 33 of the cover and screwed into the threadedbore 35. Upon unscrewing thescrews 50, the cover can be separated from the rear box. Owing to the bayonet coupling between the hinge and the cover, removal of the screws will not cause separation of the hinges, and therefore the door, from thecover 30. While carrying out this operation, the operator does not need to take care of holding both the cover and the door to avoid that either or both may fall and get damaged. The door remains secured to the cover, whereby it is sufficient to use one hand to take hold of either the cover or the door to prevent both from falling. - In the embodiment shown in figures 8 and 9, the
hinge body 11 forms anabutment surface 13a within thecylindrical passage 13 for thehead 51 of thescrew 50. Similarly, the two-diameter bore 33 has anabutment surface 36 for the rear or free end of thebush portion 12. When thescrew 50 is tightly screwed in thethreaded bore 35, thehead 51 prevents thehinge device 10 from being accidentally removed from the rest of the enclosure. Owing to the fact that the mechanism for coupling the hinge to the cover is formed integrally with these two parts, each hinge is associated to only one screw. The smaller the number of screws, the less is the risk of losing one of them when the cover is disassembled. The coaxial arrangement of thescrew 50 with respect to thebush portion 12 and the bayonet coupling mechanism allows the manufacturing of very compact hinge, having a body even much smaller than the one illustrated by way of example in the attached drawings. - Furthermore, it will be appreciated that the provision of two pintles or securing points on each hinge device guarantees that the door will be steady also in case one of the two pintles (of plastic material) is broken.
- It is understood that the invention is not limited to the embodiment described and illustrated here, which is to be considered as an example of implementing the hinge device. Rather, the invention is open to modifications concerning the shape and layout of parts, constructional details and materials used. In a further alternative embodiment (not shown), the quick coupling bayonet mechanism may be replaced by a different kind of quick coupling, preferably threaded. For example, the outer surface of the
bush portion 12 may form a number of inclined ribs providing a thread for cooperating with corresponding radial reliefs formed in thecover bore 33. Preferably the inclination of the ribs will be chosen such that the hinge body is fixable to the cover by rotating it a fraction of a turn, typically one fourth turn.
