[0001] The present invention relates to a covering element for pits of automotive workshops
or the like.
[0002] As is known, safety regulations require that, at pits of automotive workshops or
the like, a covering element be provided which is constituted substantially by a plurality
of bars that are arranged mutually side by side and are made to slide by way of motor
means that execute the movement thereof.
[0003] EP1849935 discloses a solution that involves using a shutter covering that is actuated by way
of motor means that move the shutter, which is constituted by a plurality of bars
that slide within guides that must be positioned on the longitudinal edges.
[0004] At preset intervals, some of the bars have engagement rollers that couple with auxiliary
guides so as to enable the gathering of the shutter, with the pit in the open position,
thus arranging the bars in laterally adjacent swags.
[0005] This implementation solution, which has been shown to be valid under various aspects,
has been particularly suitable for use with newly-constructed pits, but its installation
has been found to be more complex at existing pits.
[0006] EPA 2258913 discloses a covering element for pits of automotive workshops or the
like which comprises a shutter covering made from a plurality of bars that are arranged
mutually side by side and are joined by chain links that support pins and have a bracket
for supporting the bars; the chain links are further mutually connected by way of
link plates.
[0007] In this case too the covering element is slideably guided in longitudinal guides
that are arranged at the longitudinal edges of the pit.
[0008] At regular intervals, elongated pins are connected to the bars which support respective
supporting rollers, which can also slide in the longitudinal guides.
[0009] In order to execute the gathering of the shutter covering in the gathering region
of the pit, at the end of the longitudinal guides which is facing toward the gathering
region, there are supporting guides that are capable of engaging only with the sliding
rollers.
[0010] In essence, the supporting guides have a narrower width than the longitudinal guides
so that they do not offer support for the sliding rollers, and thus they allow the
respective bars to fall downwardly so as to allow the gathering of the shutter covering
below the closing surface that covers the gathering region.
[0011] Such implementation solution has been found to be extremely practical and effective
to use and install on existing pits.
[0012] However, the method of storing the shutter in swags reduces, in some cases excessively,
the useful length of the pit.
[0013] The aim of the present invention is to solve the above mentioned problems, by providing
a covering element for pits of automotive workshops or the like which can be easily
installed on existing pits.
[0014] Within this aim, an object of the invention is to provide a covering element that
requires a limited provision of additional elements that in practice are constituted
solely by sliding guides to be positioned at the longitudinal edges of the pit.
[0015] Another object of the present invention is to provide a covering element that, owing
to its distinctive implementation characteristics, is capable of offering the widest
guarantees of reliability and safety in use.
[0016] Another object of the invention is to make available a covering element that makes
it possible for the pit, in the condition for use, to have an increased useful longitudinal
extension.
[0017] This aim and these and other objects which will become better apparent hereinafter
are achieved by a covering element for pits of automotive workshops or the like according
to claim 1.
[0018] Further characteristics and advantages of the invention will become better apparent
from the detailed description of a preferred, but not exclusive, embodiment of a covering
element for pits of automotive workshops or the like, which is illustrated for the
purpose of non-limiting example in the accompanying drawings wherein:
Figure 1 is a perspective view of a pit;
Figure 2 is a cross-sectional view of the pit, taken along a horizontal plane;
Figure 3 and Figure 4 are two perspective views, from two different viewpoints, of
the covering element at the gathering region;
Figures 5 to 7 are cross-sectional views of the gathering region during the re-entry
sequence of the shutter covering.
[0019] With reference to the figures, the present invention relates to a covering element,
generally indicated with the reference numeral 1, for pits 5 of automotive workshops
or the like.
[0020] The covering element 1 comprises a shutter covering, generally indicated with the
reference numeral 2, which can be arranged in a gathering region 10.
[0021] The shutter covering 2 has a plurality of transverse bars or slats 3 which can slide,
conveniently at their ends, along a pair of lateral sliding guides 4.
[0022] The lateral sliding guides 4 are, specifically, arranged at the longitudinal edges
of a pit 5.
[0023] At the gathering region 10 and proximate to the ends 4a of the lateral sliding guides
4 respective guide portions 6 are provided that are substantially vertical and open
downwardly 6a.
[0024] According to the present invention, the closure element 1 has a pair of gathering
guides 7, which are arranged at the lateral sides of the gathering region 10 below
the open ends 6a of the substantially vertical guide portions.
[0025] The gathering guides 7 extend substantially parallel to the longitudinal ends of
the lateral sliding guides 4.
[0026] The shutter covering 2 further comprises a plurality of gathering bodies 8, which
are associated with some of the sliding bars 3 and are mutually spaced apart along
the longitudinal extension of the shutter covering 2.
[0027] The gathering guides 7 can, in particular, engage only with the gathering bodies
8, with the bars 3 that are not associated with gathering bodies 8 being arrangeable
in laterally adjacent swags.
[0028] Preferably, at least the bars 3 that are not associated with gathering bodies 8 have
supporting bodies 9 for sliding along the lateral sliding guides 4.
[0029] Advantageously, at the ends 7a of the gathering guides 7 which are facing toward
the respective vertical guide portion 6, there is a section of guiding portion folded
upwardly in order to engage with the gathering bodies 8 during the step of entry of
the shutter covering 2.
[0030] Conveniently, the bars 3 are connected, at the respective ends, to pins 9a and to
elongated pins 8a, which support, respectively, the sliding bodies 9 and the gathering
bodies 8.
[0031] According to a preferred embodiment, the sliding bodies 9 and the gathering bodies
8 comprise, respectively, sliding rollers and gathering rollers.
[0032] With reference to the embodiment shown in the figures, the covering element 1 comprises
motor means 12 for the movement of the shutter covering 2.
[0033] Conveniently, as shown in Figures 5-7, each gathering guide 7 has a sub-horizontal
progression with the lowest level at the opposite end from the vertical guide portion
6.
[0034] Preferably, the longitudinal ends of the bars 3 are connected to chain link elements.
[0035] By way of example, the motor means 12 comprise a motor that actuates a pair of pinions
11 that enmesh between the rollers of the chain links.
[0036] According to a particularly important aspect of the present invention, the distance
between the free edges of the mutually opposite lateral sliding guides 4 is less than
the distance between the free edges of the mutually opposite gathering guides 7.
[0037] Conveniently, the gathering bodies 8 are positioned at regular intervals.
[0038] Advantageously, the shutter covering 2 comprises chain links and link plates that
mutually join the pins 9a and the elongated pins 8a for a connection in the manner
of a chain.
[0039] In essence, the gathering guides 7 have a narrower width than that of the longitudinal
sliding guides 4, such that they do not offer support to the sliding rollers 9, such
that the respective bars 3 fall downwardly when they are brought to the gathering
region 10 and, in particular, at the gathering guides 7.
[0040] The gathering toward the end of the gathering guides 7 arranged at the opposite end
with respect to the substantially vertical portion 6 is facilitated by the inclination
of the gathering guides 7 themselves.
[0041] In substance, by having gathering rollers 8 at regular intervals which support the
respective bar 3, then when the shutter covering 2 is pushed toward the gathering
region 10, only some of the bars 3 remain held in the gathering guides 7 while the
other bars 3 fall freely by gravity, arranging themselves in swags which are arranged
mutually side by side, allowing an easy gathering of shutter covers 2 including those
of considerable length.
[0042] In substance, therefore, the particular structure with gathering rollers 8 that are
positioned with a broader width than that of the sliding rollers 9 ensures that arranging
the gathering guides 7 at a lower height than the extension of the longitudinal sliding
guides 4 which engage only with the gathering rollers 8 automatically leads to the
free descent of the bars 3 that are provided with sliding rollers 9 at the gathering
region 10.
[0043] From the foregoing explanation, it can be seen that the invention fully achieves
the set aim and objects.
[0044] In particular, specifying that the gathering guides 7 are arranged below the end
portions of one of the supporting guides 4 has made it possible to increase the useful
length of the pit 5 thus making it possible, among other things, to have the motor
means 12 positioned above the gathering guides 7.
[0045] The embodiment that is the subject matter of the present invention further makes
it possible to provide the individual components such as the sliding guides 4, the
gathering guides 7, the substantially vertical portions 6 and the assembly that supports
the motor means 12 and the toothed racks 11 in a modular manner, associating them,
without any difficulty, with pits 5, including existing pits, of dimensions, both
transverse and longitudinal, that are mutually different.
[0046] The invention, thus conceived, is susceptible of numerous modifications and variations,
all of which are within the scope of the appended claims.
[0047] Moreover, all the details may be substituted by other, technically equivalent elements.
[0048] In practice the materials employed, provided they are compatible with the specific
use, and the contingent dimensions and shapes, may be any according to requirements.
