Description

MODULAR ELEMENT OF UNIVERSAL TOOL SUPPORT AND APPLICATION TO A
UNIVERSAL TOOL SUPPORT PANEL.

 The present invention relates to a modular element of universal tool support, suitable for tools of different sizes, and the application to a universal tool support panel.

 It is common to hang, on a common panel, a set of various DIY tools constituting an assortment.

The simplest modes of tool suspension consist of hooks, nipples, points, orifices of a perforated plate, or the like, fixed on a vertical panel and intended to retain a bulged part of a tool (handle or tool head) to prevent. fall of the tool. According to this summary support mode, the tools are free to pivot around their support and are not securely retained so that this attachment mode is reserved for fixed panels and cannot be applied to transportable panels . Furthermore, the imprecise positioning of the various tools limits the density of storage of the tools on the support panel.

 Tool storage units have also been proposed in the form of panels or boxes, in which each tool has a suitable housing which ensures secure holding and immobilization of the tool. These storage units are, however, often of complex construction and cannot be adapted to a change in the composition of the collection of tools, since the tools are not interchangeable on their supports when these tools are of different type or different size.

 The present invention aims to remedy the aforementioned drawbacks and to allow the production, at a reduced cost, of a tool support assembly which is compact and adaptable to different types of tools of various sizes, while ensuring that it is kept in a secure position. for each of the tools, so that such a tool support assembly can in particular be transported without difficulty.

 The invention also aims to allow the production of a support assembly of modular design tools for can be increased or decreased without difficulty to adapt to the needs of the user.

 Another object of the invention consists in producing an assembly of tool support means which makes it possible to place the tools in the support elements, and to withdraw the tools quickly and with ease.

 These aims are achieved by means of a modular universal tool support element, comprising support means attached to a vertical rear wall, characterized in that it comprises first and second flat vertical guide walls spaced apart from one of the other substantially parallel to each other, substantially perpendicular to the rear wall, and of limited length of between approximately 35 and 70 mm, a downward retaining element made integral with the rear wall and disposed in the vicinity of the upper part of the vertical walls guide and a front stop integral with the retaining element, substantially parallel to said rear wall and disposed relative to the latter at a distance of between approximately 12 and 40 mm.

 The invention relates more particularly to a modular element of the aforementioned type for supporting a tool with a single handle, characterized in that it has a channel delimited laterally by the first and second guide walls and completely open on its faces front, bottom and top.

 In this case, advantageously, the retaining element constituted by the upper edges of the first and second guide walls has, from the vertical rear wall, a first substantially horizontal portion extending over approximately half the depth of the walls. guide, a second portion inclined upward forming with the horizontal an angle of the order of 250 to 500, and if necessary a third vertical portion of low height formed by the upper edge of the front stop.

 Other alternative embodiments are possible, however, with in particular upper flanges of guide walls which, starting from the vertical rear wall, have a first portion slightly inclined downwards then a second portion inclined upwards with a more steep slope. strong.

 The invention also relates to a modular element with vertical guide walls of the above-mentioned type, for supporting a tool with two articulated branches of the pliers, pincers, shears type, comprising in the space between the first and second vertical walls of guiding a downward retaining element constituted by an elongated part perpendicular to the rear wall, of U-shaped or inverted V-shaped section, and a front stop constituted by a plate substantially perpendicular to the elongated part forming a retaining element.

 The invention also relates to a modular element for supporting tools of various sizes comprising support means attached to a vertical rear wall, characterized in that it comprises a rectangular frame constituted by a vertical rear face pressed against the wall rear, two vertical side faces spaced from each other by a predetermined distance of between approximately 50 and 80 mm, and a vertical front face disposed at a distance of between approximately 12 and 40 mm relative to the rear face, in that the frame is provided at its rear part with hooking means on the vertical rear wall, in that at least one pair of flat vertical guide walls spaced from one another, substantially parallel to one another, substantially perpendicular to the rear wall and integral with the frame extend downward from the frame over a limited length of between approximately 35 and 70 mm and in that at least one retaining element is provided v ers the bottom substantially parallel to the side faces of the frame and disposed inside the frame being integral with it.

 Such a modular element having a standard frame can be adapted to serve as a support for two tools with handle or on the contrary to serve as a support for a tool with two articulated branches.

 The invention further relates to a universal tool support panel, comprising a rear vertical wall, an intermediate vertical wall disposed at a distance of between approximately 12 and 40 mm relative to the rear wall, of lower height than the latter. and joined thereto by external side walls, at least one vertical guiding partition parallel to said side walls to define in the receptacle delimited by the rear, intermediate and lateral side walls a plurality of tool receiving modules with two branches articulated, each module delimited by two adjacent parallel guide walls spaced by a distance of between approximately 50 and 80 mm, further comprising a central downward retention element constituted by an elongated support parallel to the guide walls and connecting the upper part from the intermediate wall to the rear wall, and in that a plurality of handle tool receiving modules are dis placed on the front face of the intermediate wall, halfway up the latter.

XIX-XIX of figure 18;
FIG. 1 shows in perspective the mounting of three modular tool support elements 10, 20 removably attached to a support panel 1 provided with openings 2 distributed regularly over the entire surface of the panel 1. According to this embodiment, each module 10; 20 presents a frame 30; 40 of standard size provided at its rear part with hooking means 17; 27, 28 of the hook type provided for engaging in the openings 2 of the panel 1, the dimensions and spacings of which are compatible with the position of the hooks 17; 27, 28.

 The basic modular elements 10, 20 are divided into two categories suitable for two types of tool, but have a frame of the same dimensions provided with similar attachment means 17, 27, so as to be interchangeable on the panel 1. By elsewhere, the modular elements all have the same design and are designed to effectively keep in position a tool of the current type, whatever its size, in a relatively large range of dimensions, while allowing the user to engage or remove the tool without effort or delicate handling.

 For this, each elementary module 10, 20 (Fig 2 and 3) comprises a pair of flat vertical guide walls 12, 13 respectively 22, 23 spaced from each other and perpendicular or practically perpendicular to the rear face. 11, respectively 21 of the frame 30 respectively 40 provided to come to bear against the vertical panel 1. The guide walls 12, 13 or 22, 23 have a limited length, to twist from 35 to 70 mm, but sufficient to ensure a lateral support of the tool engaged between these walls. Each elementary module further comprises a front stop constituted in the case considered by the front face 15, respectively 25 of the support frame 30; 40, and a downward retaining element 14, respectively 24 made integral with the rear face 11, respectively 21 of the frame 30 respectively 40 intended to be applied against the panel 1. The retaining element 14; 24 extends between the rear face 11; 21 and the front face 15; 25 of frame 30; 40 parallel to the side faces 16; 26 of the frame, over a distance which is between approximately 12 and 40 mm.

 The modular element 10 shown in FIG. 2 is more particularly suitable for supporting a tool with a single handle, such as a screwdriver, a file or a wood chisel for example.

The modular element 10 which is provided for the support of two tools with a single handle is characterized by the presence of two channels 18 'delimited laterally by two guide walls 12, 13, each channel 18 being completely open on its front, lower faces and higher. The front face 15 of the frame 30 which constitutes a front stop for the tools is interrupted only at the level of each channel 18.

 The frame 30 located at the top of the modular element 10 thus comprises a rear face 11 two side faces 16 and a front face 15, the latter being simply interrupted at each of the channels 18. The side faces 16 of the frame 30 are essentially parallel to the pairs of guide walls 12, 13, but are offset towards the outside with respect to the latter. In the embodiment of Figure 2, for each tool engaged in a channel 18, a front stop 15 is constituted by two wings substantially vertical and perpendicular.

eyelets to the first and second guide walls, 12,13 delimiting a channel 18, these two wings extending outward relative to the channel 18. The bulged part of the tool, which is in principle the lower end of the handle rests on a downward retaining element 14 which is constituted by the upper edges of the guide walls 12, 13 delimiting the channel 18 in which the element of smaller section of the tool is engaged, for example the file proper if it is a file.

 The guide walls 12, 13 are joined to the lower part of the rear face 11 of the frame 30 and are also joined to the parts 15 of the front face of the frame 30 constituting a front stop for the tools. The modular element of Figure 2 can thus be made in one piece, for example plastic.

 Each retaining element 14 constituted by an upper rim of one of the guide walls 12 or 13 has, from the rear wall 11 of the frame 30, a first substantially horizontal portion extending over approximately half the depth of the walls guide 12, 13, a second portion 19 inclined upwards and, if necessary, as shown in FIG. 2, a third vertical portion of small height constituted by the upper edge of the front stop 15. The inclined portion 19 of the upper rim 14 forming a downward retention element for a tool makes it possible to press the handle of the tool against the rear face 11 of the frame 30 whatever the diameter of the handle of this tool and thus guarantees good positioning of the tool in the modular support element 10.

 The engagement of a tool in the tool holder 10 is very easy since it suffices to pass the threaded part of the tool through the channel 18 and then to let the handle rest inside the frame 30 on the edges 14, 19 of the guide walls 12, 13 to prevent the tool from escaping downward or forward. The vertical guide walls 12, 13 which delimit a channel 18 moreover prevent tilting movements of the tool in the lateral direction.

 FIG. 3 represents a modular support element of a tool with two articulated branches, for example of the pliers, pincers, shears type, which comprises a frame 40 similar to the frame 30 of the modular element 10, but without any interruption on its front face 25. The frame 40 composed of a rear face 21 of two lateral faces 26 and of a front face 25 has a rectangular shape and has dimensions similar to those of the frame 30, so that the modular elements 10 provided for tools with a handle or the modular element 20 provided for tools with two articulated branches can be mounted indifferently on a common panel (FIG. 1). For this, the frame 30 and the frame 40 of the elements 10 and 20 are provided with hooking elements 17, respectively 27 which are of the same nature.

 The modular element 20 comprises two fairly spaced vertical guide walls 22, 23 which are only very slightly offset inwards relative to the lateral faces 26 of the frame 40. The guide walls 22, 23, which can carry elements additional attachment 28 could however be aligned with the lateral faces 26 of the frame 40. As can be seen in FIGS. 11 and 14, the lateral walls 22, 23 for guiding a tool with two branches are provided for retaining laterally the branches of the tool. The tool itself is itself held down by an element 24 which is placed in a central position inside the frame 40, is parallel to the lateral faces 26 of the frame 40 and has preferably a U-shaped or inverted V-shaped section which allows both to separate the two articulated branches of the tool in order to make them abut on the guide walls 22, 23 and to avoid, during the setting of the tool, jamming retaining element 24 with any insulating fittings with which certain tools are provided. The retaining element 24 is integral with the rear 21 and front 25 walls of the frame 40. The front wall 25 also serves as a stop for the tool, the branches of which are engaged inside the frame 40 and are then retained by the guide walls 22, 23.

 With reference to FIGS. 1 to 3, modular support elements for tools of various sizes have been described, comprising support means integral with a rectangular frame 30; 40, provided with attachment means 17; 27, 28 in order to allow the attachment of the modular elements 10; 20 on a vertical panel 1 provided with opening 2. The invention is not however limited to the implementation of removable modular elements, but also takes into account the implementation of modular elements for supporting tools rendered permanently attached to a rear vertical wall 1. In this case, each modular element always comprises at least one pair of vertical guide plates 12, 13 respectively 22, 23, downward retaining means and a front stop , but it is not essential to produce a complete frame such as the frame 30 or the frame 40 of FIGS. 1 to 3.

 We will now describe with reference to FIGS. 4 to 10 the essential constituent elements of a modular element for supporting tools with a handle, such as for example a file 3, represented by dotted lines in FIG. 4. FIGS. 4 to 7 relate to the same embodiment, while FIGS. 9 and 10 show variants of this embodiment.

 FIG. 7 clearly shows the presence of a channel 18 delimited laterally by two guide walls 12, 13 and completely open on its front, bottom and top faces. The modular element of Figure 7 which is provided for the support of a single tool has a front stop 15 consisting of two wings substantially vertical and perpendicular to the guide walls 12, 13 and extending outwardly relative to the channel 18. Substantially horizontal wings 17 oriented outwards with respect to channel 18 are also attached to the upper part of the guide walls 12, 13.The guide walls 12, 13 terminate at their upper part by a flange having a portion 19, which can be rectilinear, and which has an inclination upwards while being oriented in such a way that the highest end is situated on the side of the front abutment 15. More particularly, in the mode of embodiments of FIGS. 4 to 7, the retaining element of the handle of the tool 3 is constituted by the upper edge of the guide walls 12, 13, which upper edge has from its rear end a first sense portion ibly horizontal referenced 14, extending over about half the depth of the guide walls 12, 13, a second portion 19 inclined upward and forming with the horizontal an angle of the order of 250 to 500, and a third vertical portion of low height formed by the upper edge of the front stop 15 (Figure 4).

 Alternatively, as can be seen in Figure 8, the upper edges of the guide walls 12, 13 may have from the rear end, that is to say the rear vertical wall 1, a first portion 14A slightly inclined downward forming with the horizontal an angle of the order of 30 to 100 and extending over approximately one third of the depth of the guide walls, and a second portion 19A inclined upward forming with the horizontal an angle of the order of 350 to 750. This alternative embodiment has the advantage of positioning the tool in a slightly inclined manner so that the lower part of the tool abuts against the wall 1 , this being made possible by the fact that the wall 14A is not strictly horizontal, but is slightly inclined relative to the horizontal.

 FIG. 9 shows another variant of the embodiment of FIGS. 4 to 7. According to this embodiment, the flanges of the guide walls 12, 13 forming a downward retention element simply comprise a first horizontal portion 148 extending at barely over half the depth of the guide walls and only a second inclined portion 19B which is directly attached to the upper end 15 of the front stop of the modular element.

 In all cases, the presence of a first horizontal or substantially horizontal part 14, 14A, 148, then at least a second part 19, 19A, 19B inclined upwards on the side of the front stop 15 allows the handle to the tool 3 arranged in the modular element to be pressed against the vertical rear wall 1, whatever the caliber of the tool and of this handle.

 The lower part of the tool is in all cases guided laterally by the guide walls 12, 13 of limited length, but sufficient to prevent tilting of the tool.

The length of the walls 12, 13 can be between approximately 35 and 70 mm.

 The width of the channel 18 can advantageously be between approximately 5 and 15 mm. The height of the front stop 15 relative to the horizontal part 14, 14A, 148 can be between approximately 10 and 30 mm.

 The depth of the channel 18, that is to say the distance between the front stop 15 and the vertical rear wall 1 can be between approximately 12 and 40 mm.

 FIG. 10 shows an alternative embodiment in which the two guide walls 12, 13 referenced 12A, 13A are not strictly parallel to each other and perpendicular to the rear wall 1, but are slightly divergent by defining a channel 18 whose width is larger on the side of the opening located in the vicinity of the front stop 15, than in its rear part close to the vertical wall 1. The walls 12A, 13A can for example define between them an angle of between approximately 3 and 60. The configuration of Figure 10 allows both to easily introduce the tool into the channel 18 and to position this tool appropriately, depending on its caliber, while ensuring that the tool will be maintained in a well defined position.

 FIGS. 11 to 16 relate to a modular tool support element designed to receive tools with two articulated branches, such as for example pliers 4 with movable articulation (FIG. 11), universal pliers 5 (FIG. 14), a pair of pliers or shears. The modular element which will be described with reference to FIGS. 11 to 16 does not include a frame 40 like the modular element 20 of FIG. 3, but comprises several essential characteristic elements fixed directly to a rear vertical wall 1.

The modular element shown in FIGS. 11 to 13 comprises two vertical guide walls 22, 23 which can be quite similar to the walls 22, 23 of the module 20 of FIG. 3, and have a length preferably between 30 and 50 mm. The two vertical parallel guide walls 22, 23 advantageously have a spacing of between approximately 50 and 80 mm. An elongated element 24 with an inverted V-shaped section or
U upside down is arranged parallel to the walls 22, 23 at mid distance therefrom and is attached to the vertical rear wall 1. A plate 25 forming a front stopper is itself disposed at the front end of the element 24 perpendicular to the guide walls 22, 23. A clamp 4, the branches of which are introduced between the guide walls 22, 23 is held down by the element 24 and is prevented from tilting forward by the front stop 25 The clamp 4 is moreover well maintained in the lateral direction by the guide walls 22, 23.

 Figures 14 to 16 simply represent an alternative embodiment of the modular element of Figures 11 to 13. According to this variant, the front stop 25 is made integral not only with the retaining element 24, but also with the guide walls 22, 23. Furthermore, the retaining element 24 has a more rounded shape than in the case of FIG. 11.

 We will now describe an application of the modular elements according to the invention to a universal tool support panel. In FIG. 17, the reference 1 designates a rear vertical wall and the reference 101 designates an intermediate vertical wall disposed at a distance of between approximately 12 and 40 mm relative to the rear wall 1, and having a lower height than this wall rear 1. The intermediate wall 101 is joined to the rear wall 1 by external lateral walls 110, as well as by two vertical guide partitions 122, 123, parallel to said lateral walls 110, but having a limited length of the order of 35 at 70 mm for example. The receptacle defined by the rear wall 1, the external lateral walls 126 and the intermediate wall 101 is divided by the guide walls 122, 123 into three modules 120 for receiving tools with two articulated branches.

 Spacers 124 forming a downward retaining element, of a configuration similar to the elements 24 of FIGS. 11 and 14, are arranged between the intermediate wall 101 and the rear wall 1, in the vicinity of the upper rim 125 of the intermediate wall 101, and are each located midway between two adjacent side partitions spaced a distance of between about 50 and 80 mm. Each element 124 is arranged in the central part of the module. In the example of FIG. 17, the vertical guide walls of the module 120 on the left are formed on the one hand by an external side wall 126 and on the other hand by an intermediate partition 122. It is the same for the module 120 located to the right of the panel, for which the vertical lateral guide walls are constituted by an external lateral wall 126 and by an intermediate partition 123. On the other hand, for the central module 120, the vertical guide walls are constituted exclusively by partitions intermediaries' 122, 123.

 The intermediate wall 101 itself in turn serves as a rear vertical wall to receive modular elements for supporting tools with handles, such as screwdrivers, scissors, files.

A series of modular elements 110 which may be in all respects in accordance with the description given with reference to FIGS. 4 to 10, are arranged at mid-height on the front face of the intermediate panel 101. In FIG. 17, the elements 112, 113, 114, 115, 117 and 118 are similar to elements 12, 13, 14, 15, 17, 18 of the modular elements of Figures 4 to 10 and will therefore not be described again. Likewise, the inclined part 119 corresponds to the inclined parts 19, 19A, 19B of FIGS. 4, 8 and 9 and will therefore not be explained in more detail below. The front stops 115 integral with the vertical guide walls 112, 113 situated at the lateral ends of the panel can be connected by lateral walls 116 to the lateral walls 126 described above.

 The modular elements according to the present invention can be used in various tool support assemblies, and in particular in tool holder boxes as will be described by way of example with reference to FIGS. 18 to 19.

 The modular tool support elements according to the invention can be arranged very compactly and moreover ensure precise maintenance of tools of different caliber and even of different kind, so that they are particularly suitable for being incorporated in a transportable tool holder assembly.

 The toolbox of FIGS. 18 and 19 comprises a base 201 surmounted in its central part by a double panel 205, the upper end of which defines a handle 206 under which a clearance 207 is formed. A cover 300 is engaged on the tool box and comes to rest on low walls 202 attached to the bottom 201. The cover 300 is itself provided with a handle 310 which is superimposed on the handle 206 secured to the double panel 205 on which are fixed tool holder assemblies . A clearance 312 is however provided under the handle 310 of the cover in order to be able to selectively remove the cover 300 by only grasping the handle 310 or, on the contrary, carry the whole of the tool box with its support 205 and its cover 300 by grasping at both the handle 206 and the handle 310 of the cover. In the example shown in FIG. 19, the handles 310, 206 are produced so as to present in their upper part a V-shaped groove making it possible to immobilize a part arranged on the upper face of the cover 300, so that it also plays, if necessary, the role of a workbench.

 In the tool box of FIGS. 18 and 19, modular support elements for tools with two articulated branches such as pliers are placed on both sides of the double central panel 205, while vertical side walls 203, 204 perpendicular to the bottom 201 and the double wall 205 serve as a rear panel for carrying modular elements of tools intended to support tools with handles, such as screwdrivers for example.

The modular tool-carrying elements 10 or 20 shown in FIGS. 18 and 19 will not be described in more detail insofar as these can be quite similar to the embodiment described above.
