BACKGROUND TO THE INVENTION
[0001] The present invention refers to a modular blind which may be used both for windows and doors.
[0002] The blind described in this invention comprises slats which may be connected by connection profiles which are rolled round a winding shaft.
[0003] The blind is characterised in that it has been conceived on the basis of various types of element for the purpose of providing various possibilities for configuration based on the distribution of said elements according to the user's requirements and wishes. Therefore the blind comprises at least two of the following types of element joined by means of coupling profiles: slats which include safety means, slats which provide the possibility of letting in light, conventional blind slats and connection devices for dividing the blind into individual panels.
BACKGROUND TO THE INVENTION
[0004] As is known, conventional blinds already exist and also other blinds which possess added characteristic functions such as for example, safety blinds which cannot be opened from the outside or mosquito blinds which permit light through perforated slats.
[0005] In all cases these blinds already have a pre-established configuration and cannot be custom designed to suit the end user.
[0006] The invention proposed resolves the aforementioned disadvantage as it enables combination of slats and profiles which interconnect so that it is possible to obtain a blind which fulfils various functional characteristics based on the express requirements of the client.
[0007] For example, blinds are known of the type known as Majorcan, which are provided with the means of rotating the slats, so that the sun can enter. However, in addition to the fact that these do not permit any modularity, they incorporate costly rotation mechanisms which require a large winding volume.
A previous similar invention may be cited in utility model application U8900808 entitled "Safety device for roller doors or blinds" which describes a blind comprising slats provided with connecting profiles which act as a connecting link between the aforementioned slats. These profiles are normally designed to achieve an adequate articulation between the slats, although in this invention their configuration is such that they permit wedging in the lateral guides of the blind. In this way they ensure that when an attempt is made to lift the blind from outside they wedge in the lateral guides, thus preventing opening of the blind. The connection profile between the slats has longitudinal ends wound in opposing directions and with different curve amplitude in order to determine the respective open tubing which enables coupling of the profile with the possibility of rotation of the semi-tubing ends of the adjacent slats.
[0008] Another previous utility model with application no. U200501469 is that entitled "Blind with improved slats" which describes a blind formed through a grouping of slats which could be termed conventional and which is divided into an upper panel and a lower panel such that it is possible to open an intermediate space between both panels for the entry of air and light. In order to facilitate the retention of the upper panel of the blind in the area where both panels divide, it is provided with a connection device.
DESCRIPTION OF THE INVENTION
[0010] Blinds normally comprise slats which may be joined together by connection profiles such that they define a slat which, in extended position, covers the space of the door or window in which it is installed. They are also provided with a winding axle around which the blind is wound as it rises.
[0011] In addition to the basic function of covering a space such as a door or window, blinds may fulfil other functions such as, for example, that of providing safety functions with some type of mechanism or device which prevents it being raised from the outside. There are other types of blinds which are provided with the adequate means for permitting the entry of light and air although not the entry of insects, or the possibility of dividing the blind panel into two independent panels so that it is possible for the user to open a space between both panels.
[0012] The invention proposes a configuration in which by means slats of different types and coupling profiles it is possible to achieve totally modular blinds such that it is possible to devise a blind which may have several of the aforementioned functional qualities depending on the user's requirements and wishes.
[0013] According to the foregoing, the blind which is the subject of this invention comprises at least two of the following types of element joined by means of coupling profiles: slats which include safety means, slats which provide the possibility of letting in light, conventional blind slats and connection devices for dividing the blind into individual panels.
[0014] In this way the user may choose a combination of these different elements based on his/her tastes or requirement and may in addition situate them at any point of the blind deemed appropriate.
[0015] It will possible for example, to vary the indoor light by selecting the desired points of light on the blind, that is, in sections of said blind where it is desired to let in light, which is achieved by means of various punched holes or micro perforations, varying from small holes which prevent the entry of insects up to perforated areas which may be personalised with advertising elements.
[0016] Similarly the client may select specific self blocking points by use of the slats and safety profiles. Safety blinds are currently fitted with a system of slats and blocking elements throughout their structure which ensures that they cannot be breached. By means of the present invention the client chooses the sections where they will be placed, which may be a lower, intermediate or higher section or a combination of these since it is sufficient with sections 4 or 5 of this type of pairs of slats and profiles to ensure the impenetrability of the blind.
[0017] Another advantage of the present invention is that relating to the relatively frequent need for replacing an already installed blind with another for example a safety blind. In this case the work becomes very complex as it is necessary to change the case as there is a need for greater volume when storing the safety blind in its interior. With the proposed invention, as only sections of safety blind are used and coupling profiles with other conventional sections or light sections, the volume of the blind is similar to that of the existing blind and the case can be reused with the concomitant saving of time, materials, and costs.

PREFERRED EMBODIMENT OF THE INVENTION
[0027] According to the description of the invention the main types of element which may be integrated in the blind which is the object of the invention are as follows:
- Safety (1.1) slats (1) which in the preferred embodiment correspond to the embodiment of the safety slats (1.1) pertinent to utility model with application number U8900808. The slats (1.1) comprise a slightly curved profile which is provided at its ends with respective tubing open in opposite directions. These tubings fit with connection profiles (1.1.1) which are provided with curved longitudinal ends in opposite directions and with different curve amplitude and which centrally possess an essentially rectilinear area which produces wedging in the lateral guide in which the blind is installed when an attempt is made to lift it from the outside.
- Light (1.2) slats (1) which may comprise a single piece, part of which consists of a perforated zone which allows light to pass through or either consisting of two independent elements, light slats (1.2.1) that is, perforated slats intercalated with opaque slats (1.2.2).
- Conventional blind(1.3) slats (1)that is, those which do not possess any additional function which may be, for example, of the type represented in figure 2, which has an open lower end and an upper end which is provided with an element which hooks onto the open end of the slat situated above.
- Connection devices for dividing independent panels or which is in fact the same, the means for enabling division of the blind into at least two independent panels so that it is possible to open up a space in the centre of said blind. This device may be similar to that disclosed in utility model application no. U200501469.
[0028] In addition, among the various sections of slats (1) described above having various functions there are coupling profiles which permit their interconnection. In the preferred embodiment and according to the various possible combinations of slats(1) there are two types of coupling profiles for connecting slats (1) of a different type:
- Coupling profiles between sections of safety slats (1.1) and light slats (1.2) represented in figure 3.
- Coupling profiles between conventional winding slats (1.3) and light section slats (1.2) represented in figure 4.
[0029] Both types of coupling profile are constituted on the basis of two differentiated ends. Each of the ends of the profile is joined to a different type of slat (1) which is also provided with a different type of end, such that each coupling profile is provided with two ends antagonistic to the form of the end of the slat (1) to which it is coupled.
[0030] More specifically, in the preferred embodiment, the coupling profiles (2,3,4,5) are formed by two ends coinciding with the form of the ends of the slats (1) or connection profiles which are articulated to the slats (1) with which the aforementioned coupling profiles ( 2 ,3, 4, 5) are coupled. That is, the profiles (2,3,4,5) are formed by two halves with each corresponding to the form of the end of the slat (1) or connection profile which would be joined to the slat (1) in which the coupling profile is hooked (2, 3, 4, 5).
[0031] Figure 3 shows the coupling profiles (2, 3) between the light slats (1.2) and the safety slats (1.1) one of the profiles (2) is provided with two ends curved in different directions, the end (2.1) which attaches to the section of safety slats (1.1) which are arranged above it has the form of the end of a connection profile (1.1.1) of a safety slat (1.1). In addition, the other end (2.2) has the same form as one of the ends of a perforated light slat (1.2.1).
The coupling profile (3) which joins one section of light slats (1.2) which is situated above a section of safety slats (1.1) is formed by an upper end which has the form of an end of the perforated light slat (1.2.1) and a lower end (3.2) which has the form of an end of a connection profile (1.1.1) between safety slats (1.1).
[0032] Figure 4 represents coupling profiles (4, 5) between the light slats (1.2) and the conventional slats (1.3). The coupling profile (4) which joins one section of light slats (1.2) with a lower section of conventional slats (1.3) is formed by an upper end (4.1) which corresponds to an end of a perforated light slat (1.2.1) and a lower end (4.2) which corresponds to an end of a conventional slat (1.3).
[0033] The coupling profile (5) corresponding to the coupling between an upper section conventional slats (1.3) and a lower section of light slats (1.2) also has two differentiated ends with the upper end (5.1) corresponding to the end of a perforated light slat (1.2.1).
[0034] An additional characteristic of the blind which is the subject of the invention is the possibility of total darkness, that is, the sections or slats (1.2.1) through which light passes are overlapped by opaque slats (1.2.2) which enable total closure of the blind, as occurs in conventional blinds. In the case of the preferred embodiment, the perforated light slats (1.2.1) would be concealed in the respective end openings (1.2.2.1) of the opaque slats (1.2.2) That is, the concealment of the perforated light slats (1.21)is both above and below the opaque slat (1.2.2) which enables a maximum amount of light in respect of the light configurations of traditional blinds in which there is only concealment on one of the sides of the opaque slat (1.2.2)
[0035] In the preferred embodiment the perforated light slats (1.2.1) may adopt curved convex forms such as those represented in figure 5. The ends of these slats (1.2.1) may be quadrangular in form (1.2.1.1), with the object of blocking their rotation within the openings (1.2.2.1) of the opaque slats (1.2.2) preventing the light slats (1.2.1) and the opaque slats (1.2.2) from becoming unhooked. However, the ends of these perforated slats (1.21) may also have a circular form (1.2.1.2).
[0036] All the slats (1) described have housing for lateral caps which prevent longitudinal movement between them and which are fixed to these by means of screws or by pressure.
Figure 6 shows two possible configurations in which there is an opening (6) in which a lock or other configuration based on flanges (7) may be inserted and which have the same function as well as enabling the use of caps. These slats may be situated at any height of the blind as an additional safety measure.
[0037] The modular blind is joined in its upper part to the winding shaft (8). These shafts may have different configurations, for example, cylindrical, octagonal, hexagonal or similar. In order to attach the modular blind a tie rod is used (8.1) which normally comprises a strip which is inserted at one end in the shaft grooves (8) and at the other end it is joined to an oscillating profile which is connected to the first slat (1) of the modular blind. Another form of attachment of the blind to the shaft (8) could be by means of a bolting the first slat (1) to the shaft of the winding reel (8).
[0038] The modular blind which is the subject of the invention consists of a winding reel shaft (8) see figure 7 which is provided with a rabbet (8.2) on its surface such that the aforementioned rod(8.1) or the first slat (1) with its corresponding screw are situated on this rabbet (8.2) The rabbet (8.2) is proportional to the thickness of the slat being wound.
[0039] The object of this embodiment is that when the blind is wound up it does not create a bunching of slats in the area which would be over the rod (8.2) or on the screw so that the wound up blind on the winding reel shaft (89 would be elliptical instead of circular. As a result the blind is not distributed in a uniform manner in the winding reel shaft (8) requiring the user to apply additional force to counteract the inadequate distribution of the weights thereof. Another disadvantage of elliptical distribution of the blind is that it requires more space inside the case when it is fully wound.
[0040] In order to ensure that the remaining elements of the blind that is the cord disc, the socket or the motor coupling and the counter in the event that the blind is motorised, can adapt to the shaft (8) which includes the aforementioned rabbet (8.2)these elements are provided with a flat wall the plane of which coincides with a hypothetical shaft cord (8) so that this flat wall adapts to the rabbet (8.1) as it remains tangential to the ends thereof (8.1)
[0041] The shaft is provided with a central hole (8.3) for placing the socket which is situated centrally with respect the greater radius of the shaft (8).
[0042] In addition, the blind which is the subject of the invention comprises a means of contact with the shaft (8) in order to facilitate the blind winding. These means are places in the upper part of the blind so that they are not seen by the user. Therefore, an initial section of slats (1) is provided which, due to their form, remain perfectly coupled to the surface of the shaft (8) as they are wound onto said shaft, thus facilitating the winding in other sections of slats (1) as there are no angular parts between the slats (1).
In the preferred embodiment the means for facilitating the winding consist of at least a combination of perforated light slats (1.2!) with base slats (1.4) Nevertheless the perforated light slats (1.2.1) may be provided with perforated slats or they may be totally opaque that is, they may not be perforated. The base slats (1.4) represented in figure 8 are provided with respective end openings (1.4.1.) separated by a central partition (1.4.2). In this way the longitudinal dimensions of the slat (1.4) with respect to the opaque slats (1.2.2) of the light sections are reduced, thus ensuring that it is more adjusted to the shaft (8) and therefore achieving winding with less volume.
It is also possible to include a section of base slats (1.4) and perforated light slats (1.21) which would occupy a greater band than that referred to previously, formed in this case by light slats in which the perforated slat (1.2.1) is substituted by an non-perforated slat that is, totally opaque. In this way it is possible to avoid the undesirable effect when totally extending the blind of an upper section of slats which are not sufficiently close together, thus allowing light to penetrate.
The elements of the modular blind may be made from materials which will make the blind durable thus increasing its security. The materials used are preferably carbon fibre, aluminium, steel or stainless steel.
