The disclosure relates to releasable hand tool holders and more particularly to an apparatus for securely and releasably holding sockets which can be readily positioned on and removed from the tool holder.
For a more complete understanding of the present invention, and the advantages thereof, reference is now made to the following description which is to be taken in conjunction with the accompanying drawings in which like reference numerals indicate like parts and wherein:
Socket tools, or simply sockets, are universally used by professional and amateur mechanics and maintenance technicians and come in sets of various size and style. Storing and organizing sockets is a challenge due to their various sizes, shape, and typical numbers in a set.
Commercially available socket holder apparatus typically provide a series of individual socket holders in a straight line configuration along a central rail or tool body. The sockets are attached and released by hand, such as by push-on, pull-off action or by half-turns and the like, from a holding post or similar. The sockets held on the socket holders are in close proximity to one another and adjacent sockets can “rattle” or impact one another, especially during transport of the apparatus in a vehicle. Repeated contact eventually results in damage to adjacent sockets such as flaking chrome or coating, scratches and dents and the like.
Some socket holders are mounted to move along a rail or tool body without any way to secure the socket holders to specific locations. For larger socket sizes, adjacent sockets bang into one another every time the rail or body is tilted sufficiently to cause the holders to slide and when the rail is rotated to or through a generally vertical orientation. Even on an apparatus having a way to secure the socket holders into selected positions, the holders sometimes come loose by accident, vibration, part failure, or wear, resulting in unwanted and damaging rattling or sliding of adjacent sockets into one another. Secure and spaced positioning of adjacent socket holders on a tool holding apparatus to prevent contact between adjacent sockets is needed.
While the sockets are typically marked with identifying information, often by stamping of the exterior surface of the socket cylinder, it can be difficult to read the information, especially where the sockets are positioned in a line where the information can be obscured by adjacent sockets.
The body 12 has a base 18 designed to sit on a relatively flat surface. The base 18 defines a bottom surface 20 of the body 12. In an embodiment, the bottom surface 20 of the body 12 is defined by a generally flat perimeter 22 as shown. In alternate embodiments, the bottom surface 20 can define a generally flat planar wall, a contoured surface, a plurality of feet, etc. In an embodiment, as shown, the bottom surface 20 is made of a non-slip material such as rubber, silicone or the like, including Thermal Plastic Rubber (TPR), Thermal Plastic Elastomer (TPE), or silicone rubber. The non-slip material assists in maintaining the tool holder in a selected position on a surface, particularly a surface which is at an angle to the horizontal, such as on a typical hood, trunk, roof, or other vehicle part, or on a vibrating or moving surface, such as on an idling vehicle or a table supporting an operating power tool or motor or the like. The non-slip bottom surface 20 can be integrally formed with the body 12, attached to the body 12 by fasteners, adhesives or friction fitting, removably attached to the body 12, etc. In an embodiment, the bottom surface 20 is attached to the body 12 by a manufacturing process referred to as overmolding.
The base 18 can also include finger holds 24 allowing for ease of lifting the tool holder 10 from a surface. The tool holder 10 loaded with sockets has substantial weight and can be difficult to lift or to “pry” from a flat surface. The finger holds 24 provide a surface for the user to grasp or lift. Alternately the finger holds 24 can be apertures in the body 12, contours shaped into the body 12, or grips of non-slip material attached to the body 12.
The body 12 defines at least one platform 26 for positioning of the held sockets. The platform 26 is elongate to define a row 14 of posts 16 and a row of sockets when in use. A platform 26a can define an elevated surface, that is, generally flush with the height of the wall 30, as seen in row 14a in
The body 12 can take various shape depending on the types and sizes of tools to be held, the arrangement of held tools, the aesthetics of the holder, etc. The base 12 as shown includes an opposed front wall 30 and back wall 32, and opposed side walls 34. The walls in some embodiments are connected to one another. In some embodiments the walls are generally vertical. In some embodiments, as shown, some or all of the walls can be angled with respect to the vertical.
The body 12 can also include sloped surfaces 38a and 38b defined, for example, between the generally horizontally planar surfaces or platforms 26a and 26b. The sloped surface 38a, for example, can form the front wall 30 or a portion thereof. In other embodiments, a generally vertical front wall 30 and a sloped surface, such as surface 38a, may both be present. The planar surfaces 26a and 26b can be at different heights to allow for ease of socket placement and removal, positioning of sockets of different sizes at different levels, separation of sockets of different sizes, types, drive socket shapes, socket heads, or measurement standards (SAE, metric), etc. As seen in
The holder body 12 can be made of various materials. In embodiments, the holder body 12 is made of plastic, such as ABS, nylon, polycarbonate, polypropylene, etc., and can be manufactured using a mold. Such materials and manufacture allow for a wide variety of body shapes and sizes at a reasonable expense.
The tool holder 10 can also include a labelling assembly 50. The labelling assembly 50 includes markings 52 to convey information about the tools, such as markings indicating socket sizes in SAE or metric sizes. The labels can comprise embossing, etching, silk-screening, engraving or other markings directly onto the body 12, such as seen in
The labels 54 can attach to the body 12 by attachment means as known in the art. For example, the labels 54 can be attached, removably or permanently, by cooperating posts 58 and holes 59, slidable labels and rails 60, tongue and groove, snap-on assembly, etc. The labels 54 can attach to the body such that they are slidable along the length of the body, for example. The user can be provided with a plurality of interchangeable labels 54, fixedly or removably attachable to the body 12 at the user's selection. For example, a kit can be provided having a plurality of labels for SAE and metric measurements, socket type, drive socket type, socket head type, etc. The labels can be color-coded or otherwise visually differentiated.
In the embodiment shown in
Each clip member 60 is removably attachable to the body 12. For example, the clip member 60 can slide on or snap on to the body at cooperating contours, indentations, apertures, etc., defined in the body 12. In the embodiment shown, each clip member 60 slidingly and grippingly engages grooves 70 defined in a wall 30, 32 or sloped surfaces 38 of the assembly body 12. As shown, the clip member 60 can have a central plate 62, opposing legs 72, and flanges 74. The central plate 62, in the illustrated embodiment, extends across a platform 26. The legs 72 can conform to the sloped surfaces 38, recess walls, or other surfaces of the body 12. The grooves 70 are grippingly engaged by the flanges 74 and the clip member is maintained on the holder assembly 10. In an embodiment, the legs 72 of the clip members are flexible and the clip member is “snapped” into an engaged position by pressing the clip member downward onto the assembly.
Alternately, the clip members 60 can be slidingly engaged onto and removed from the assembly body 12. In an exemplary embodiment, the body 12 defines a cross-section which cooperates with the clip member 60, allowing the clip member 60 to readily slide along the body 12 at grooves 70. An end cap (not shown) can be removably mounted to the assembly body 12, allowing clip members 60 to be slid onto the assembly body 12. In embodiments utilizing clip members 60 which are slidably attachable to the body 12, the posts 16 must be removable from the body, as explained elsewhere herein, such as by unscrewing from the holder or by also slidably attaching to the body.
In an embodiment, the clip members are constrained against rotational movement in relation to the assembly such as by interference between opposing legs of the clip member and a wall of the assembly.
The clip members 60 further include displayed markings 52 corresponding to the sockets held by the posts 16. The markings can be positioned on the clip central plate 62, leg 72, or other surface defined on the clip member 60. Alternately, a label plate can be used, similar to those described above herein with regard to
The markings 52 provide socket identification information, for example, socket size in metric or standard units, and/or socket type, and/or indications for locking and unlocking the socket from the socket holder. The markings on any given clip member can be identical or different to other such markings.
Further, the clip members and body can comprise an orientation guide to insure clips are positioned in the correct orientation on the body. For example, as shown, the clip members 60 have a front leg 72 which is positioned at an angle corresponding to that of the sloped surface 38.

In
The user can be provided with a plurality of interchangeable clip members 60, fixedly or removably attachable to the body 12 at the user's selection. For example, a kit can be provided having a plurality of labels for SAE and metric measurements, socket type, drive socket type, socket head type, etc. The labels can be color-coded or otherwise visually differentiated.
Socket wrenches, ratchets and other driving devices typically come with square drive heads which fittingly receive any of a corresponding set of sockets with similarly sized drive sockets. A socket typically has a socket head for receiving a fastener and a drive socket for receiving the drive post of the wrench, ratchet or other driving device. The socket head defines a fastener-shaped hole for receiving the head of a fastener. For example, a hex (hexagonal) head socket will drive a hex head fastener of the same size. The drive socket of the socket defines a hole for receiving the drive post of the drive device, such as a ratchet wrench. For square posted drive devices and drive sockets, standard sizes are typically one-quarter inch, three-eighths inch, and one-half inch square. (E.g., a “quarter inch drive socket”.) Larger sizes are rarer but include standard sizes of three-quarter, one, and one and a half inches square.
For a set of sockets having a given size drive socket, multiple sockets are provided for various sized fasteners. For example, a quarter inch drive socket set might include thirteen sockets having a range of sizes and shapes for different fasteners. In
Additionally, socket wrenches and drive devices are available having a “spline drive.” A spline drive uses a drive post with multiple splines (e.g., six) defined along the length of the drive post. The corresponding sockets obviously have splined drive socket holes for use with the splined drive post.
Typical sized sockets weigh between around 10 and 40 grams, although the weights depend on the socket material, the depth of the socket, the socket type, etc. For example, impact sockets are thicker walled and weigh more than standard sockets. Deep sockets are longer than standard “shallow” sockets and consequently weigh more. Some larger and smaller sockets are available and will weigh more or less.
The posts 16 can take various shape in cross-section. For example, the posts can be square, hexagonal, octagonal, round, etc. in cross-section. Square posts, however, may make it difficult to fit a square holed socket onto the post. The square socket hole would need to be rotationally aligned with the post, for example. The same is true for an octagonal post, for example. A cylindrical post would provide only four contact points with the walls of the square hole in the socket.
In one embodiment, the posts 16 have a central body 80 which is splined, as shown, having a plurality of longitudinal splines 82 running the height of the post 16. A splined post 16 can be especially useful for use with square drive sockets. In the embodiment shown, the post 16 has six splines 82, which can be said to roughly define a hexagon when the tips of the splines are connected by imaginary lines. Similar posts having fewer or more splines can also be used. The post surfaces 84 between the splines can, for example, define a cylinder, hexagon, etc. The post surfaces between the splines do not contact the socket in use. One benefit of having six equally spaced splines 82 is that such a post provides for six points of contact 86 with the drive hole wall 90 of a square socket drive while not requiring rotational alignment between the socket and post.
A columnar post 16 (with circular cross-section), for example, would provide four points of contact 86 with a square socket drive hole wall 90. A square-column post 16 (with a square cross-section) would provide contact with the square drive hole wall 90 along its entire perimeter, but it would require rotational alignment of the socket and post. That is, the user would have to rotate the socket to the proper orientation to position the socket on the post. A four splined post would have the drawback of either requiring rotational alignment of socket and post or requiring spline diameters of greater size than the corner-to-corner dimension of a square drive hole. An eight splined post design results in unused splines (not contacting the socket), or requiring different dimensions from spline to spline, and rotational alignment.
In some embodiments the posts 16 are made of Thermal Plastic Rubber (TPR) or Thermal Plastic Elastomer (TPE). Alternate materials include silicone rubber. These materials provide resiliency and elasticity while also relatively easy for a user to force These materials are also resistant to chemical breakdown upon exposure to common but corrosive fluids such as brake cleaner and transmission fluids.
In some embodiments, the friction fit between a post 16 and positioned socket I such that the entire holder assembly 10 can be held upside down and the socket will not disengage from the post. The post is made of a material, as described, for providing a high friction between post and socket. Further, the post is sized and shaped to provide a solid friction fit between post and socket. Further, the post is made of (or covered in) a suitable elastic material to deform when the socket is positioned on the post and to then provide a positive elastic force against the socket. In some embodiments, a holding force of greater than 10 grams is provided by the fit between the friction post and the socket. In some embodiments, a holding force of greater than 10 grams is provided by the fit between the friction post and the socket. In some embodiments, a holding force of greater than 400 grams is provided by the fit between the friction post and the socket. In some embodiments, the friction fit force is great enough to allow the entire assembly, loaded with sockets, to be held by grasping only a single socket positioned on a post.
Overmolding is a manufacturing technique using consecutive moldings to create a monolithic item. For example, a single item is created by manufacturing a first part (a substrate) of a first material and then “molding over” the first part with a second material to create the unified single part. The substrate can be a machined metal part, a molded plastic part, etc. The substrate is partially or fully covered by the subsequently applied overmold materials which are injection molded into a mold tool formed around the substrate. When the overmold material cures or solidifies, the two materials become joined together as a single item. The resulting continuous item is composed of chemically bonded and often mechanically interlocked materials of different types. Overmolding materials can be plastic, rubber, Thermal Plastic Rubber (TPR) or Thermal Plastic Elastomer (TPE), for example.
In some embodiments, the friction post socket holder is manufactured using overmolding techniques. In
Using the overmold technique, the holder 10 parts (first molded underlay and second molded overlay) are chemically and physically locked together. The perimeter is both chemically bonded to the body and mechanically interlocks with the body. For example, the perimeter 22 has interlocking tabs 94 which cooperate with notches defined in the body 12. Further, the platform sheets 28 and posts 16 are overmolded onto and into the body 12. The surface sheets 28 are chemically bonded to the underlying platforms 26 of the body. The sheets 28 are also mechanically interlocked with the body where, for example, overmold material columns 96 cooperate with corresponding apertures in the body 12.
In an embodiment, the posts 16 are entirely made of overmolded material. In another embodiment, the posts comprise a harder substrate covered by a softer overmold material. Overmolding insures that the perimeter 22, sheets 28 and posts 16 do not separate or detach from the body 12, either entirely or at random points between the overmold and substrate. The resulting holder 10 is of solid, unitary construction, and is tough and reliable.
Use of appropriate overmold materials provides a soft, gripping layer for contacting ferrous surfaces and chrome plated sockets which are prone to scratching. Further, the overmolding allows for a suitably flexible and resilient material to form or overlay the posts 16. Finally, the overmold process eliminates assembly parts such as fasteners, potentially reducing or eliminating fastener costs, scratching of sockets and surfaces by fasteners, machining time and costs for the holder body, and assembly time and costs for the holder generally. The overmolding also allows for colorful aesthetics (since the substrate and overmold can be of different colors).
An apparatus 100 for releasably holding by friction fit posts 16 a plurality of socket tools includes a rail assembly 112 and plurality of socket holder assemblies 114 which slidably and removably engage the rail assembly 112.
The exemplary rail assembly 112 defines a generally U-shaped channel 122 having a bottom wall 116, opposing side walls 118, and opposing flanges 120.
Exemplary socket holder assemblies 114 slidably engage the rail assembly 112 as shown. The holder assembly 114 includes a post 16 and a base member 132. The base member 132 cooperates with the rail assembly 112.
Assembled socket holders are also seen in
In an exemplary embodiment of a socket holder assembly 114, the base member 132 engages the channel 22. The base member 132 is of a size and cross-section to slidingly engage the rail assembly channel 122. Flanges 140 defined on the base member 132 cooperate with, slide within and maintain the holder assembly 114 in the channel 22. More particularly, the flanges 140 of the base member 132 slide into and engage the corresponding grooves 142 defined by the rail assembly walls 116, 118 and flanges 120. The bottom surface of the base member 132 may include friction (or anti-friction) features to reduce (or increase) the force required to slide the socket holder assembly along the rail assembly. As seen in
In the embodiment seen in
Each clip member 160 slidingly and grippingly engages grooves 190 defined in the exterior surfaces of the side walls 192 of the rail assembly body 14 in some embodiments. The clip member 160 has central plate 162, opposing legs 172, and flanges 174. The central plate 162, in the illustrated embodiment, rests on the base member 132 of the socket holder assembly 114. The grooves 190 are slidably engaged by the flanges 174 and the clip member is maintained on the rail assembly by engagement between the grooves 190 and flanges 174. In an embodiment, the legs of the clip members are flexible and the clip member is “snapped” into an engaged position by pressing the clip member downward onto the rail assembly. Alternately, the clip members can be slidingly engaged onto and removed from the rail assembly.
In an embodiment, the clip members are constrained against rotational movement in relation to the rail assembly. The clip member is constrained against rotational movement in relation to the rail assembly by interference between opposing legs of the clip member and at least a side wall of the rail assembly.
Adjacent clip members or adjacent socket holder assemblies can abut one another defining a minimum spacing between adjacent, mounted sockets of the same or similar diameter. As described elsewhere herein, sockets come in varying diameters. Consequently, in some embodiments, the socket holder assemblies 114 can be provided in varying lengths to accommodate the varying sizes of socket. Similarly, the clips can be a varying length.
In some embodiments, the rail assembly, socket holder assembly, and/or clip assembly can further includes orientation guides for proper orientation of these assemblies with one another. An orientation guide may require a base member 132, and therefore socket holder assembly 60, to be inserted into the interior channel 122 at a specified orientation. Thus, a set of socket holder assemblies would “face the same way” in the channel. For example, cooperating orientation mechanisms can be used on alternate assemblies. For example, one of the grooves 190 can employ an alternate profile which cooperates with a flange 140 of corresponding profile, thereby requiring orientation of the base member 132 in a specified orientation with respect to the rail assembly. Similar mechanisms can be used to orient the clips on the rail assembly.
The magnetic back plate assembly 200 is attached to the assembly body 12, by friction fit, adhesive, fasteners, slide-in assembly (e.g., tongue and groove), a picture-frame assembly, or as otherwise known in the art. In the illustrated embodiment, the magnetic back plate 200 is mounted to the holder body 12. The magnetic back plate assembly 200 is, in the shown embodiment, comprises a plurality (two) of magnetic panels 202. The magnetic back plate assembly allows the holder assembly 10 to be securely positioned on any suitable ferrous surface.
