Description:
A Cargo Fixing Mechanism for Vehicles

Technical Field

Invention relates to a fixing mechanism providing stabilization of cargos/properties developed for use in loading areas of cargo carrying vehicles such as trunks of cars, bus, trucks etc.

State of the Art

Today cars or cargo carrying vehicles carry cargos of various sizes and shapes. Various solutions have been developed to keep properties stabile in parking position, while driving or on inclined roads. Thus properties can be kept stabile, no damage to properties or vehicles is provided and driving comfort of vehicle is not affected.

In current applications, systems comprising rails and holding member allowing travel on rail to loading trunk or loading zones for fixing cargos to vehicle are used. When systems available in the related art are examined, it is seen that they comprise a holding member to hold cargo in general, a rail compatible with geometry of holding member to provide housing of holding member and allowing travel thereon. Some embodiments also use a coating part to enhance visibility of rail used for fixing. This causes extra work force, cost and weight.

Another disadvantage observed in the current related art is that area designed in a manner to have extensions and raising enabling grasp of holding member providing fixing onto rail is subject to high stress due to acceleration of fixed cargo and vehicle.

Another technical issue experienced in the related art is that holding member is attached to rail from the tip or attached from an opening that allow passing through holder structured on rail. In case of attaching from tip of holding member, a level difference is encountered between rail and loading surface, which causes decrease in loading capacity. In case of attaching holding member to system via an opening, losses in needed area on rail for fixing operation are caused. In some applications wherein holding member is fixed from only one side perpendicular to movement direction, the stress on extension-raising surfaces where holding member is fixed increases and movement of holding member may be affected. In other current technical applications, spaces are observed between extension raising structures on fixing rail securing position of holding member and contact surfaces of holding member. This status causes problems such as noise, vibration and fatigue during movement of vehicle in particular due to the fact that contact surfaces comprise hard material on both sides.

One of the patents encountered in literature is an application numbered DE102013204261 B4. Said application aims to provide security of user by help of a weakened area provided on rail in case of a vehicle crashed from behind to fix cargo thereon. Said application does contain extension-raising areas providing fixing the holding member of which advantages and disadvantages are described above.

During search, a patent numbered DE102017208175A1 is encountered. Said application relates to a rail cross-section comprising functional members. Said rail cross-section suggests solutions such as fixing to vehicle base by means of some functional parts and passing through some structural cables. However, extra functional parts added thereto increase workmanship and cost.

As a result, due to above described disadvantages and inadequacy of existing solutions it has been necessary to make development in the related art.

Purpose of the Invention

Present invention relates to a fixing mechanism providing stabilization of cargos/properties developed for use in loading areas of cargo carrying vehicles such as trunks of cars, bus, trucks etc.

Primary purpose of the invention is to provide a fixing mechanism used in cargo/property carrying areas of vehicles of low cost and workmanship and long life.

Another purpose of the invention is to decrease cost and workmanship thanks to single part of rail as a part of fixing mechanism.

A further purpose of the invention is to provide reduction of stress in area on the part having holding openings used for fixing holding member onto rail and thus spreading thereof. Thus it allows lightening of the part and production of single part by use of lower strength material. A similar purpose of the invention is to provide fixing holding member onto rail without area loss. Holding member can be added onto rail in a position of stopping at an angle close to 90 °to its own working direction and after attachment to rail, is rotated 90° on vertical axis and full mounting can be provided.

Another purpose of the invention is to provide better strength and more stabile motion under both static and moving circumstances thanks to grasping openings perpendicular to holding member and rail working direction on right and left as well as grasping forms.

Another purpose of the invention is to reduce noise and vibration by help of grasping arms having geometric adaptation with grasping openings on rail structured holding member. In addition, grasping arms made from softer polymer material in comparison to current materials provides longer life.

In order to achieve above mentioned purposes, a fixing mechanism comprising a rail connected to loading area, at least a holding member located onto said rail and allowing fixing cargos/properties, at least a grasping opening formed on said rail, structured to provide fixing of holding member at desired point, at least a moving grasping arm providing fixing of holding member to said grasping opening at working position, at least an activator located on holding member, driven by a force applied externally and providing movement of grasping arm and fixing member providing slide of holding member on rail and providing movement thereof and fixing cargos/properties is developed.

Detailed Description of the Invention

Fixing mechanism (10) of the invention in its basic form comprises a rail (20) connected to loading areas of vehicles and at least a holding member (30) sliding and moving on said rail (20) and providing fixing cargos/properties in preferred section.

Figure 1 is a perspective view of fixing mechanism (10) of the invention. Rail (20) can be connected to base, side walls or ceiling of loading area of vehicle in any form. Rail (20) comprises at least a grasping opening (22) structured to provide fixing holding member (30) at desired point. Said grasping openings (22) are preferably located aligned and facing each alongside surfaces of rail (20) and/or at certain intervals. Rail (20) is made from preferably aluminium alloy to provide lightness. Grasping openings (22) can be embodied in any form. As grasping openings (22) can spread stress forming on it during fixing cargo/property around its axis and increases use life of fixing mechanism (10). Preferred round or elliptic structure of grasping openings (22) provides spread of stress around its axis, which occurs during fixing cargos/properties. Thus use life of fixing mechanism (10) is increased.

Holding member (30) comprises at least a grasping arm (31) located thereon and capable to move. Grasping arms (31) are connected to holding member (30) preferably by means of pin to provide movement. In a preferred embodiment of the invention, grasping arms (31) are at least two arms on side surfaces of holding member (30) on right and left) to lock into grasping openings (22) located on rail (20) side surfaces. But it can also be more subject to preference. Having grasping arms (31) in multiple number and/or two sides provides distribution of stress produced by cargo. Grasping arms (31) are coated by coating (32) preferably made from polymer material (plastic, rubber etc.). Thus friction is eliminated, in addition to increase in use life, noise is prevented in case of gaps between grasping openings (22) during driving. Grasping arms (31) preferably matching grasping openings (22) geometry pass through grasping openings (22) and provides fixing onto rail (20). Said holding member (30) comprises at least an activator (40) located thereon. After said activator (40) is located on holding member (30) it is positioned at a point accessible from outside. Activator (40) provides movement of grasping arms (31) on the holding member (30) as a result of force applied externally. Holding member (30) also comprises at least a fixing member (50) providing sliding and moving of holding member (30) on the rail (20) and where fixed properties/cargos are connected (not shown in Figure 1). After holding member (30) is located on the rail (20) said fixing member (50) is positioned at a point accessible from outside.

Working principle of fixing mechanism (10) of the invention is described below. Upon force applied to activator (40), grasping arms (31) move and open outward from centre of holding member (30). Upon removal of force applied to activator (40) via holding member (30) located to desired point on the rail (20), grasping arms (31) are released and pass through grasping openings (22) and are fixed onto rail (20). When it is desired to change place of holding member (30), force is applied to activator and grasping arms (31) are opened. When desired fixing point is reached, force is removed and grasping arms (31) are passed through grasping openings (22) as a result of movement to holding member (30) center and thus fixed. Cargo is secured to holding member (30) by means of fixing member (50) on holding member (30) and fixed at desired point.

Figure 2 is a perspective view of an alternative embodiment of fixing mechanism (10) of the invention. Rail (20) can be connected to base, side walls or ceiling of loading area of vehicle in any form. There is an opening (21) along surface of rail (20) facing loading area. Said opening (21) allows location of holding member (30) onto rail (20) and movement thereof along the rail (20). Rail (20) comprises at least a grasping opening (22) structured to provide fixing holding member (30) at desired point. Said grasping openings (22) are preferably located aligned and facing each along side surfaces of rail (20) and/or at certain intervals. Said grasping openings (22) can also be provided on the surface facing loading area if desired. Rail (20) is made from preferably aluminium alloy to provide lightness. Grasping openings (22) can be embodied in any form. Preferred round or elliptic structure of grasping openings (22) provides spread of stress around its axis, which occurs during fixing cargos/properties. Thus use life of fixing mechanism (10) is increased. Holding member (30) is seated onto rail (20) by means of opening (21) on the rail (20). After holding member (30) is seated onto the rail (20), some part of it remains on therail (20) and other part inside the rail (20). Said holding member (30) comprises at least an activator (40) located thereon. After holding member (30) is located on the rail (20) said fixing member (50) is positioned at a point accessible from outside. Holding member (30) also comprises at least a fixing member (50) providing sliding and moving of holding member (30) on the rail (20) and where fixed properties/cargos are connected. After holding member (30) is located on the rail (20) said fixing member (50) is positioned at a point accessible from outside.

Figure 3 is a cross-section view of holding member (30) located on the rail (20). Holding member (30) has at least a grasping arm (31) located in the part located inside the rail (20) and capable to move. In a preferred embodiment of the invention, grasping arms (31) are at least two arms on side surfaces of holding member (30) to lock into grasping openings (22) that can be provided on rail (20) side surfaces. But it can also be more subject to preference. Grasping arms (31) can be structured on side only if preferred, as well as on right and left. Having grasping arms (31) in multiple number and/or two sides provides distribution of stress produced by cargo. Grasping arms (31) are coated by coating (32) preferably made from polymer material (plastic, rubber etc.). Thus friction is eliminated, in addition to increase in use life, noise is prevented in case of gaps between grasping openings (22) during driving. Grasping arms (31) preferably matching grasping openings (22) geometry pass through grasping openings (22) and provides fixing onto rail (20).

Grasping arms (31) are driven by force applied externally onto activator (40) on the holding member (30) and moved towards centre of holding member (30). Upon movement, the grasping arms (31) get out from said grasping openings (22) and slide on the rail (20) and thus provides free motion for holding member (30). When force is applied to activator (40), grasping arms (31) is pulled inside in a manner holding member (30) remains inside external surface inside rail (20).

In a preferred embodiment of fixing mechanism (10) of the invention, holding member (30) can be fitted and removed without any loss of area on rail (20) and easily. In order to provide it, opening (21) width (A) on the rail (20) is to be bigger than width (C) of holding member (30). Thus holding member (30) is passed through opening (21) on the rail (20) and part comprising grasping arms (31) remains in a manner parallel to rail (20). Figure 4 is a front view of holding member located inside rail in state of not in working status (no rotation/twisting). Then after rotation of holding member (30) 90 degrees in any direction it comes into working position. Figure 5 is a side and regional cross-section view of holding member (30) on the rail (20) in working position. In order to rotate part of holding member (30) remaining in inner part of rail (20) 90 degrees, the length (D) of holding member (30) should be smaller than inner width (B) of the rail (20). As seen in figure 3, grasping arms (31) coming into working position pass through grasping openings (22) and thus fixing is provided.

Working principle of a preferred embodiment of the invention is as follows. Holding member (30) is placed onto rail (20) by means of opening (21) on the rail (20). Then after rotation of holding member (30) 90 degrees it comes into working position. Grasping arms (31) located on the holding member (30) coming into working position pass through grasping openings (22) located on the rail (20) and thus are fixed. In case of any force applied to activator (40) externally, grasping arms (31) move towards centre of rail (20) and leave grasping openings (22) and allow movement of holding member (30) on the rail (20). It slides on the rail (20) by means of fixing member (50) and thus motion is provided. When desired fixing point is achieved, force applied to activator (40) is removed. Grasping arms (31) go into working position again and pass through grasping openings (22) and thus fixing at desired point is provided. Cargo is secured to holding member (30) by means of fixing member (50) on holding member (30) and fixed at desired point.
