[0001] This invention concerns an appliance for mounting glass sheets for curtain walling
for buildings, or ventilation and/or sun screen structures for such façades, plus
solar or photovoltaic panels.
[0002] On the one hand, various mechanical and non mechanical systems are already known
for laying and fixing glass sheets for curtain walling, the same applying for elements,
panels or the like designed to allow ventilation and at the same time form a protection
against direct solar irradiation of the glass façades of buildings.
[0003] On the other hand, the same applicant has already proposed a type of appliance conceived
for connecting and rapid assembly of uprights and transoms of shelving and/or similar
structures made of vertical and horizontal elements. Such an appliance was later implemented
for use also in assembling solid elements in the form of paving tiles or panels made
of different types of material for facing buildings.
[0004] One objective of this invention is to propose a fixing appliance that, connected
to some supporting uprights, is able to really simplify and facilitate laying of glass
sheets and the like in the formation of curtain walling, guaranteeing the safety and
stability of the resulting façade and facilitating disassembly and maintenance where
required.
[0005] Another objective of the invention is to propose a supporting appliance able to simplify
and facilitate also the laying of elements and panels of various types sloping in
regards to the vertical and horizontally and vertically arranged for the formation,
in front of the glass façades of buildings, of a barrier with a structure able both
to allow ventilation and to create a barrier against direct solar irradiation of the
façades themselves.
[0006] A further objective of the invention is to supply an appliance also suitable for
assembling solar or photovoltaic modules arranged vertically or sloping on relative
supporting structures.
[0007] These objectives and evident advantages that stem from them are achieved in compliance
with the invention, with a hook appliance according to the introduction in claim 1,
and where the body of the appliance has two vertically parallel and transversely joined
flanges, and said flanges are provided with constraining for the elements to support.
[0008] According to a way of construction such constraining means include at least a vertical
base plate on which the glass sheets are laid and fixed to form a curtain wall.
[0009] According to another way of constructing said constraining means comprising basically
U shaped slots or indents provided in the vertical flanges, spaced in parallel, opening
in opposite directions, one towards the top and one towards the bottom, and equally
sloping with regards to the vertical, and said slots house and support parts of the
opposite horizontal sides of the sloping elements and panels designed to form a ventilation
and/or solar irradiation barrier to be laid at the front of glass façades of buildings.
[0010] The invention will however be described in greater detail in the continuation made
in reference to the enclosed illustrative and not limitative drawings, in which:

The example indicated in Fig. 1- 4 under num.15 shows one of the supporting uprights
for laying and fixing the glass sheets 12 for the formation of glass curtain walls
with the help of a connecting appliance 13 according to the invention.
[0011] Each mullion 11 can be made of metal with a section of any shape and it is provide
on at least one side with a number of pairs of coplanar slots 14.
[0012] Each glass sheet 12, normally quadrilateral, is provided as a precaution with at
least a bore 15 near the apex of each one.
[0013] The appliance 13 comprises a body with two parallel vertical flanges 16 joined crosswise
between them by pins or screws 17 with interposition of corresponding spacers 18.
[0014] The flanges 16 of said body have, along one of their rear vertical sides, some hooks
19 paired horizontally and provided to be inserted and connected to respective pairs
of coplanar slots 14 provided along an mullion 11.
[0015] Between the two flanges 16 of the body of the appliance are assembled a blocking
lever 20 and a possible safety lever 21 both placed basically vertical and with a
spring 22 placed between them.
[0016] The blocking lever 20 is assembled on one of the intermediate pins 17' between the
flanges 16 and is oscillating between an operating blocking position and an inoperative
released position. On the upper part, said blocking lever 20 has a pair of pawls 20'
that are facing towards the hooks 19 of the flanges and which are coplanar, and for
example, just above the pair of upper hooks 19. Lower, the blocking lever 20 has an
engaging and thrust tang 26.
[0017] The possible safety lever 21 can have two lateral fins 24 at the top housed and constrained
in apertures 25 provided in the flanges 16 so as to be basically hanging from said
flanges and susceptible to oscillating between an active and an inactive position,
to respectively stop and release the blocking lever 20. The safety lever 21, moreover,
can be prepared to engage with its lateral fins in notches 25' provided in one side
of the apertures 25 to stop it in the inactive release position of the release lever
20. Also the safety lever 21 can have an engaging tang 29.
[0018] The spring 22 is positioned so as to act and maintain the blocking lever 20 normally
in its blocked position and the safety lever 21, where provided, in its active position.
[0019] In front of the flanges 16 of the body of the appliance is provided an anchoring
plate 27, preferably quadrilateral, placed vertically and provided with at least a
bore hole 28 each proximal to its apex. The anchoring plate 27 can be one piece or,
as shown in the drawings, it can be made up of two opposite elements 27, 27 associated
between them, fixed between the flanges 16, for example, by means of a pair of pins
17" and each one having at least a pair of bore holes 28, 28.
[0020] In order to operate, the connecting appliance 13 is attached to the slots 14 of the
mullion 11, at the required height. When the hooks 19 are inserted into their respective
slots 14 the blocking lever 20 moves into its operating position. The relative stop
pawls 20' find space to insert themselves automatically into the same slots 14 in
which the upper hooks 19 of the flanges of the appliance (Fig.2) are constricted which
hold the upper hooks of the flanges of the appliance (Fig. 2), thus preventing the
upwards return movement of the deposit (Fig. 2), thus preventing the return movement
upwards towards the appliance 13 making it impossible for it to disengage from the
mullion 11. Consequently, the removal of the appliance 13 can only be carried out
intentionally by acting on the lower tang 26 of the blocking lever 20 that is to make
it move towards the release position, in which the blocking tangs 26 move out of the
slots 19.
[0021] Once connected and fixed to the mullion 11, the appliance 13, in plurality with other
appliances equally spaced horizontally and in height, assembled in the same way on
other mullions 11, it is ready to lay the sheets of glass 12 to construct curtain
walls (Figs. 3 and 4).
[0022] The sheets of glass fitting side to side will then be resting against the base plate
27 and fixed to them, perhaps with the interposition of elastomeric material washers,
by means of bolts 30 inserted in coincident bores 15, 28, present, respectively, at
the tops of the base plates and each glass sheet.
[0023] Also the body of the connecting appliance 113 in Figs. 5-8 comprises; two parallel
vertical flanges 116 joined crosswise by means of pins or screws 117 with interposition
of corresponding spacers 118; at least two hooks 119 along one of their rear vertical
sides, paired horizontally and designed to be inserted and connected in respective
pairs of coplanar slots 114 provided along a mullion 1, plus a blocking lever 120,
with stopping tangs 120' and a possible safety lever, not shown.
[0024] In this case, each flange 116 of the body of the appliance is equipped with at least
two slots or indents 122, 123 basically U shaped, separated in parallel and equally
sloped with regard to the vertical. One slot or indent 122 is near the rear side provided
with hooks 119, the other slot or indent 123 is near the front side of the flange.
[0025] Said slots and indents are open in opposite directions, the first downwards and the
second upwards.
[0026] To operate, the connecting appliance 113 is connected to the slots 114 of the mullion
11, at the height required. When the hooks 119 are inserted in the respective slots
114, the blocking lever 120 and relative stopping tangs 120' move into the operating
position -Fig. 6.
[0027] So, the appliance 113, in plurality with other similar appliances spaced horizontally
and in height, assembled in the same way on other mullions, is ready to apply elements
112 in the form of sheets or panels placed in order horizontally and in height to
form a ventilation and/or solar irradiation. The above mentioned elements 112 are
supported and fixed by means of elastomeric material seals 124 inserted in the slots
or indents 122, 123 of the body of the appliance 13.
[0028] Practically, every barrier element 112 is assembled and sloping between at least
one slot or indent 123 open upwards towards the top of the body of at least a first
appliance 113 on the lower level and at least one slot or indent 22 open towards the
lower part of the body of at least a second appliance 113, spaced in height above
the first appliance 13 as shown in Fig. 8.
[0029] Therefore the elements forming the required barrier are all sloping correspondingly
with regards to the vertical forming between them openings 25 for the circulation
of air and therefore the ventilation of the rear façade.
[0030] It should be pointed out that both of the appliances described can also be adapted
and used to install other types of flat elements, such as modular sun or photovoltaic
modules in sloping or vertically positions.
