Description

Fixing device perfected for wheelchair immobilization for disabled people in vehicle platforms

The present Utility Model application It consists of an improved fixing device for wheelchair immobilization for disabled people in vehicle platforms consisting of a blocking element basically formed by three pairs of lugs and an element of fixation formed by a series of fingernails. The device of fixing is part of an ingenuity that is used to immobilize the wheelchair of a disabled person, when the same with the user, you must travel inside the vehicle and more specifically on its platform.

The purpose of the invention is to improve the State of the Art of this industrial sector, conferring a greater retention force to the system as well as greater operating safety Thanks to the dimensioning of the invention is achieved a greater distribution of forces, which allows that the system can be coupled to most strips standardized existing in the market designed for this purpose, in its different ranges of alloys.

In these cases, as it is a solution conventional, these platforms are provided with strips or parallel profiles in solidarity with these, in which the chair fixing devices. Your situation on the platform it can be longitudinal or transverse to the direction of travel of the vehicle.

Applicable to this profile have been revealed multiple solutions, for example the one shown in the patent of invention USA No. 6,918,722, whose object is the "Element for embed "formed by a last in whose lower part find some tabs, specifically four, which are enter the standardized solidarity profile, by the means suitable, with the vehicle platform, blocking the element using a fork.

Another complementary solution to the previous one is described in US Patent for Additional Invention No. 2006/0104740, the "Embedding element" has been modified, modifying substantially the last fork.

The present invention relates to a fixing device to secure a standardized profile located on the platform of a vehicle, essentially formed said fixing device by a:

-

fixing element, and a

-

blocking element.

The fixing element is formed by a main part intended to fix the end of the tie rod chair support. This element has at its base some sensitively circular pins equidistant longitudinally and distanced from each other, so that they match the accommodations existing on the strip located on the vehicle platform. Said fixing element is configured so that it can welcome the blocking element.

The blocking element basically consists of a piece of inverted "U" shaped profile, whose faces parallel show some equidistant stubs with each other, preferably three per face, and with the same step of the existing accommodation on the upper side of the strip. The shape of these lugs is symmetrical to their opposites located in the other face of the referred "U". Therefore, each pair of lugs will be inserted in the existing housings in the strip located on the vehicle platform.

Both elements of the device fixing object of the present invention, the fixing and the blocking, they have as main feature that, although the passage of the pins of the first element and the pins of the second element they are equal, due to the interspersed situation of ones about to the others, their centers coincide with the midpoint of said He passed. That is to say that the pins and the lugs work with the step found.

A properly placed dock causes the plane of the underside of the pins of the locking element stay as close as possible to the plane of the lower face of the fixing element pins.

The invention object of the present Model of Utility brings significant advantages over the State of the Art, Among which we highlight:

-

Higher retention force of the blocking element.

-

Higher retention force of the retention element.

-

Possibility of application of device recommended in standardized strips existing in the market, lower alloy, thus complying with the established safety standards.

-

Best ergonomics of use.

Other details and features will go away showing in the course of the description that to given below, in what refers to the drawings that to this report they accompany, in what is shown by way of illustration but not limiting a practical embodiment of the invention.

Follow below a detailed relationship of the main elements of the invention and which are plotted in the figures attached by the corresponding number of ID:

(10) blocking element, (11) fixing, (12) strip, (13) wings, (14) tabs, (15) notches, (16) base of the strip, (17) central channel, (18) upper base, (19) fins, (20) hole, (21) longitudinal pillars, (22) lugs, (23) fingernails, (24) wall, (25) enhancement, (26) drill, (27) grooves, (28) strap fixing area, (29) space between pillars, (30) through cavity, (31) dock, (32) pin, (33) grooves, (34) flanks, (35-36) faces lateral, (37) chair.

Figure 1 is an exploded perspective of the fixing device object of the invention in which they can see the different parts of it: the blocking element (10) and the fixing element (11). You can also see the strip (12).

Figure 2 is a perspective of fixing device It shows that the element of lock (10) is displaced upwards from the element of fixing (11). In this position the device would be in condition if released from the power strip (12).

Figure 3 is a perspective of fixing device It shows that the element of lock (10) is displaced downwards relative to the element of fixing (11). In this situation the device would be in position. of work locked in the strip (12).

Figure 4 represents the device of fixation in manual interlocking position on the strip (12), the blocking element (10) is in the lowest position, its lugs (22) are housed between notches (15) of the strip (12) and the tabs (23) of the fixing element (11) are inside of the hollow section (17) of the strip (12), being centered transversely the tabs (14) of the strip (12) with respect to the tabs (23) of the fixing element (11).

Figure 5 represents the device of fixing by manually releasing the strip (12). In this figure it is appreciated that the lugs (22) of the blocking element (10) remain outside the hollow section (17) of the strip (12), remaining centered transversely with the tabs (14) of said strip (10) The tabs (23) of the fixing element (11) are centered transversely with the notches (15) of the strip (12).

In preferred embodiments of what is the object of the present invention and as can be seen in the Figure 1, the fixing element (11) basically comprises its lower part, fingernails (23) directed outwards, distributed longitudinally along the fixing element (11) and equidistant from each other, and whose profile is noticeably circular. These fingernails (23) are provided on both sides of the element fixing (11). We call the distance between these fingernails step (P2) and said step (P2) is the same as the notch step  (15) existing in strip (12), which we will call (P3). Saying fixing element (11) has an area for fixing the braces (28) (braces not shown in the drawings). Adjacent to this area for fixing the tie rod (28) find the location area of the blocking element (10) formed by a lowered portion, limited by the lateral faces (35 and 36). This location area is characterized by having in its central upper part of an enhancement (25), formed by a portion protruding upward from the upper base (26) of the lowered portion, said enhancement (25) being provided to facilitate The system maneuver. The side faces of the element of fixing (11) in the area corresponding to the fixing of the tie rod (28), that is to say where the blocking element (10) will not be coupled, grooves are provided (27). Additionally these grooves they are also provided on the sides of the area opposite the zone of fixing the tie rod (28) formed by the vertical wall (24).

The blocking element (10) is formed by a  bridge-shaped piece, at its upper base (18) of which provided fins (19) protruding to the sides and a hole (20) directed downward in transverse direction to blocking element (10). Emerging in its lower part are foreseen two longitudinal pillars (21) and parallel to each other, at whose base Bottoms are provided for some lugs (22), three in each of them that are directed down. These big tits (22), symmetrical with each other, they form a couple, so we can define that the blocking element (10) consists of three pairs of lugs (22). It should be noted that the longitudinal distance between said tetones (22), which we will call as (P1), is equal to the passage of tabs (P2) existing in the fixing element (11) and also equal to the pitch of the notches (P3) of the strip (12). The pillars Longitudinal (21) have two lateral surfaces external a longitudinal groove (33), formed by a slightly concave surface, whose function is to allow better clamping by the operator of the blocking element (10) by placing the fingers between those grooves (27 and 33) and the fins (19), and the support of the thumb in the enhancement (25). Thus, through this maneuver, the operator manages to overcome the tension exerted on the system by the spring (31), displacing the locking element (10) upwards and thus achieving unlock the terminal fixing device (12).

Both elements described above, that of locking (10) and fixing (11), are locked together by means of a pin (32) integral with the locking element (10) and fixedly housed in a hole (26) perpendicular to their faces lateral (33). Said pin (32) crosses perpendicularly the body of the fixing element (11) through a cavity intern (30) practiced in this fixing element (11) to effect. Said through cavity (30) is loosely sized so that it allows a vertical path of the pin (32), and by both of the blocking element (10), and whose travel is limited by the corresponding dimensioning. In the space defined by this through cavity (30), a spring (31) that works is located Compression The upper end of said spring (31) is supported by the upper inner face of the through cavity (30), while its lower end rests perpendicularly on the pin (32) cross integral to the blocking element (10). The tension of spring (31) works so that the locking element (10) stores to be placed in its lowest position of its route with respect to the fixing element (11).

The strip (12), as it is a solution conventional, consisting of an elongated body with a flat base (16) and hollow section, its section being open on its upper face forming a longitudinally centered channel (17). The edges that define said channel (17) are affected by notches (15) equidistant from each other, of equal configuration and symmetrical in Both edge. The areas of the edge of said channel not affected by the notches (15) are called tabs (14). The sides of the strip (12), referenced as fins (13), have a outer configuration surface curved-convex

The main novel feature of this device is that, although the passage of the lugs (P1) and the fingernails (P2) are the same, these are located interspersed with respect to the others, so that the center of the lugs (22) coincide with the center of the passage of the nails (23), that is to say that They have their steps found.

To insert the fixing device recommended in the strip (12), it must be placed supporting it longitudinally centered against the strip (12) exerting a some downward pressure, thus overcoming the spring tension (31), and when displaced longitudinally until the lugs (22) of the blocking element (10) are placed in the express housings  defined by the notches (15) of the strip (12), leaving Then the whole completely locked.

To release the fixing device recommended of the strip (12), it must be moved manually towards up the blocking element (10), overcoming the spring tension (31), and once said lugs (22) are completely out of its housings, then the fixing device until the tabs (23) of the element fixing (11) face the housings defined by the notches (15). In this position, the fixing device of the strip (12).

To facilitate the referred maneuver to the operator previously, the assembly has been given an ergonomic shape, practicing both locking and fixing elements grooves (27 and 33) in their lateral bases coinciding with both flanks of said fixing device. This way you get an easy positioning of the operator's fingers to nail and unlock the fixing device on the strip (12), see Figures 4 and 5. Also, and for the same purpose, they have been located in the  upper part (18) of the locking element (10) of fins (19) protruding sideways and from a hole (20), being the purpose of said hole (20) to give way or receive enhancement (25) existing in the fixing element (11). That solution Its purpose is that the operator supporting his thumb on the enhance (25) integral to the fixing element (11) and exerting a clamp effect with the fingers resting on the fins (19) located in the blocking element (10), it can be moved towards above.

In this type of device is so much the importance of the retention force of the blocking means of the chair (37) (not shown in the figures) on the strips (12) present on the platform, as a retention force supplementary to the previous one exerted by the fixing element (eleven). For this reason the invention regarding the State of the Art gives the device of the invention an increase in both the number of lugs (22), such as the number of fingernails (23), and on the other part makes the unlocking operation easier and safer fixing device, that is to say the locking elements (10) and fixing (11) on the strip (12).

Describe the invention sufficiently in correspondence with the attached figures, easy to understand that any modifications of detail deemed convenient, as long as it is not altered the essence of the invention that is summarized in the following claims.
