Abstract

The housing for the electrical component is formed by a series of extruded panels connected at the edges. The first edge includes a slot defined by an inner wall and an outer wall, the second edge includes a blade inserted into the slot, and the blade and the flexible wall include cooperating shoulders. The blades and slots exist at an angle to the outer surface when the rib engages an external recess to seal the outer surface at the joint. The bridge member extends to the joint to prevent it from spreading, while locking the flexible wall and supporting the internal parts. The housing can form a post or a receptacle on the post. The bridge member is connected to the end plate by screws extending through the plate so as to form an internal structure for the housing. Some of the connected panels can include cooling fins that form cooling ducts.

Description

  The invention provides power to vehicles and joints that can be formed from connecting edges of protruding panels and connecting the edges of extruded panels. It relates to a housing that can be constructed specifically for use in feeding.

  Glenn Rosendahl, issued May 28, 1996, discloses a microprocessor control system provided to supply power to multiple electrical outlets for use, for example, in a parking lot. The The central power supply conducts with a series of outlets, each arranged to supply power. Each outlet has its own microprocessor controlled control unit that is arranged to control the supply of power to the outlet. The detector unit detects the insertion of the connector plug into the outlet and compares the instantaneous current drawn by the load with a predetermined variable maximum current, only if that current is below the maximum value Activates a comparator that allows it to be pulled. If the maximum value is exceeded, the load is interrupted and is only allowed to be reconnected after the connector plug has been removed. The thermostat can be used to control the supply of power depending on the external temperature. The microprocessor can select only a portion of the cycle to power, resulting in a reduction in the total power drawn by the central power source.

  In U.S. Patent No. 5,637,028 issued on January 5, 2010, the inventor provides additional features of the above type of arrangement to power multiple vehicles from a central power source through multiple electrical outlets. A system for dispensing is disclosed that includes an outlet control unit for each of the outlets and a vehicle control unit for each of the vehicles. The outlet microprocessor switches the power supply to the outlet to the communication of data to the vehicle. The vehicle microprocessor communicates data by switching loads across the power supply that provide interaction between the microprocessors to manage power requirements and availability. The data includes data on whether the vehicle power unit is gasoline power, diesel power, hybrid power, or battery power. The microprocessor of the vehicle control unit is arranged to control a switch that provides power to a selected load in the vehicle and includes an interface arranged to connect to the vehicle's Canbus communication system.

  These arrangements require a suitable housing to position the electrical components and provide the outlet support so that the vehicle can be attached to the power source. The housing should be resistant to environmental conditions and provide a suitable structure that can be easily installed in place.

  U.S. Patent No. 5,637,028 (Patti), issued March 7, 2000, discloses a modular panel for a lighting fixture. Modular panels include elongated extruded panels of different shapes, including corner panels and flat side panels with curved cross sections. The side edges of a corner panel are spaced apart by a pair defining an extension slot to accommodate cooperating side edges of adjacent side panels for a tongue-in-groove connection. Including lip. The corner panel has evenly spaced fins along the surface that provide structural integrity as well as disperse light passing through the panel. The plurality of panels are assembled by adjacent intermediate adjacent panels that form a housing having a closed cross-section.

  Published on Aug. 15, 1989, US Pat. No. 6,099,086 (Agabekov) is surrounded by a bottom, two lateral wings, a vertically elongated opening suitable for receiving a transparent closure, and a side wing. Disclosed is an elongated lighting device having a housing with a power bar attached to the bottom inside the housing, placed in front of the elongated opening, the power bar having at least one insulating support element On top of that, the following series of electrical contact pairs are attached, each of which will receive a connection contact at the end of a current consuming element such as a tubular lamp. The top cover is snapped at the side edge on the lower boom.

  Patent document 5 (Claesson), issued July 9, 1991, is an open intended to be able to be connected together to create a closed channel structure around it. Disclose the arrangement of the profile lengths (open profile lengths). Two profile lengths of the same construction are connected together to produce a closed channel structure, each with its own flange with the desired profile and many connections protruding from the common base The elements are arranged with their channel-shaped spaces facing each other so that they are connected by the interaction between the flange and the connecting element in a tongue and groove connection.

  US Pat. No. 6,028,028 (Marrero), issued July 6, 1982, discloses a fluorescent luminaire having a housing that is flush mounted either on a corner or on a wall or ceiling surface. Has an embedded track on the back side, onto which the mounting plate slides. The front face of the housing is adapted to allow either a translucent shield for direct illumination or an opaque reflector device somewhat spaced from the housing for indirect illumination. The front reflector is snap-fastened by a center snap and two tongue and groove connectors.

  Published on November 5, 1985, U.S. Pat. No. 6,057,017 (Hoke) was attached to the top of an external post with a housing formed by four extruded right angle aluminum members interlocked together. A luminaire is disclosed wherein the housing provides a means for aligning the electrical assembly and its components in place.

  U.S. Pat. No. 6,057,028 (Baymon), issued on August 3, 1971, was connected together by interfitting flanges and pressed into the end of the post between the web and its flanges. Disclosed is a channel-shaped post portion connected by a plug wedge and concealed inside. The tongue-and-groove interlock between the flange of one channel-shaped post and the flange of another channel-shaped post cooperates with each other so that the two posts form a single substantially right-angle post. In such a way, the plug wedge is designed to cooperate with the post web and flange.

  One object of the present invention is to provide a housing formed from connected extruded panels.

According to one aspect of the invention, a housing is provided, the housing comprising:
Including a plurality of extruded panels arranged in parallel for connection at the side edges,
Each of the panels has a male connection member along the first side edge and a female connection member along the second side edge;
The male connection member is snapped onto the female connection member by insertion in a direction perpendicular to the end to form a joint therebetween,
The panels cooperate to form an enclosure defined by the panel for enclosing the electrical component.

  The housing described herein is designed primarily to house electrical components, where environmental protection, particularly when the electrical components are mounted externally, such as on a post or other ground support. Is needed. This arrangement is particularly suitable when the electrical component provides a controlled electrical outlet for supplying current to a load such as a vehicle. However, the equipment is not only in the automotive industry, but also in recreational vehicles (RVs) and marine industries known to include hook-ups for water, telephones, cables and the Internet, and possibly natural gas. Can also be used. Thus, the housing may include components for providing any one or more of these utilities.

  Preferably, the housing includes panels of different cross sections. A system in which the housing includes different types of panes that can be selected for edge-to-edge connections to form differently shaped housings for different locations of the connecting edges and to include different parts This is particularly useful when forming part of Thus, the system can include the panel itself, along with additional components that cooperate with the panel to form different structures.

  Thus, some of the panels may be generally straight in cross section and may be generally curved in cross section. Some may include a flat outer surface location. Some may include cooling fins. Some may include external and internal corners. These can be selected and combined to provide different arrangements of housings as needed.

  Preferably, to allow this selection and connection, each male connecting member of the panel has the same cross section, and each female connecting member of the panel also has the same cross section.

  Preferably, the panel is formed from an extruded metal that provides a suitable level of strength and environmental resistance, such as mild steel, stainless steel, or aluminum. However, other plastic materials can be used.

  Preferably, the housing includes a top end cap for engaging the top edge of the panel, and a bottom end cap for engaging the bottom edge of the panel, wherein the top and bottom end caps The cap is divided into compartments that connect together, and each compartment is arranged to receive a respective one edge of the panel. In this arrangement, the top cap compartments can slide together to create a lap joint. Preferably, the top and bottom end caps are the same. The end cap is a horizontal with an outermost dependent vertical wall around the outer edge of the receiving wall and an upright inwardly located wall for engaging and positioning the inner edge of the panel. A receiving wall can be included.

  Thus, there can be one end cap design for each design of the extruded panel involved.

  The end caps are either designed to be positioned at the top or to provide a base at the bottom, providing a water resistant barrier to the extrusion enclosure.

  This dynamic flexibility of the design is the same as the extrusion itself, as it consists of interconnecting male and female sides, allowing the end caps to be interconnected in any shape and size where a matching extrusion can be set. Achieved in a way. The base and top cap can be easily produced to match any design of extrusion enclosure tailored to the dynamic nature of the extrusion enclosure idea. Thus, the required housing shape can be obtained by selecting the required panel elements of the required shape, assembled from edge to edge, and these panels also interconnected at the edge. Form the housing with the associated end cap for shape.

The design includes the following features:
The end caps include male and female sides so that they can be interconnected at the same position as the matching panel extrusion.
The end caps engage by sliding together to create a lap joint that prevents water from passing through the joint and entering the enclosure.
The end caps are designed with a top that fits inside the extrusion and a bottom that fits the extrusion top and the outside of the extrusion providing a lap water seal.
The end cap is arranged at the lower end of the end cap so that there is a small ridge included in the design that provides two functions depending on the application. When closing the top of the enclosure, the ridges act as draining shelves that prevent water from flowing over the enclosure and to the sides of the enclosure, but instead the water becomes polka dots and triggers to fall to the ground at the edges. When used as a base for the enclosure, the ridge functions as a seal to the mounting surface that ensures an interference fit along the bottom of the enclosure. The ridge is the weakest point along the bottom surface, thereby allowing it to follow an uneven mounting surface that produces a better seal.

  Preferably, a plurality of bridging members are provided, each bridging the panels with a respective one of the joints between the panels, each panel receiving a bridge member insert. So that the bridge member bridges the joint inside the inner surface of the housing to prevent the joint from spreading.

  Preferably, the bridge member is connected at one end to a support member, such as a base plate or an end plate that extends normally perpendicular to the panel, so as to provide a connection between the panel and the plate. Two end plates may also be provided so that the two end plates and the bridge member form a support structure inside the panel.

  Preferably, the bridge member is fastened to the end plate by screws through a support member that engages a longitudinally extending channel of the bridge member.

  If cooling of electrical components in a high temperature environment is desired, at least one of the panels may have a plurality of coolings that typically extend outwardly from either the inward facing side or the outward facing side depending on the architecture required Fins can be supported.

  Preferably, the panels are connected and arranged at the edges such that the cooling fins form part of a cooling duct extending along the housing.

  For example, two or more of the panels may form a cooling duct located within the outer housing, with the housing being formed by the respective panel.

  In one example, the panels are connected to form an upright extension post. The extension post may be attached to a vertical sleeve member for vertical movement within the sleeve member from the retracted portion, where the post is included in a deployed position within the sleeve member, and In the deployed position, the post stands up from the sleeve member and presents the user with the manipulated parts of the housed parts. The sleeve member can be positioned on the ground so that the post can be retracted into the ground or, in some cases, attached to the ground as a concrete structural member that is resistant to damage, so that the post is protected Retract into the sleeve member.

  Thus, in one arrangement, an enclosure mounted underground is provided in the form of a post that can be elevated for use. The dynamic extrusion enclosure design described herein is used to produce an electrical post for outdoor use that is stored when not in use within the protection of an underground storage container. This design offers many advantages, including unhindered flat ground for ease of ground maintenance, avoidance of vandalism, and what is not visible to the eye until needed .

This design includes the following features:
It maintains a clean ground for ease of maintenance such as snow removal.
Electrical posts are stored and protected when not in use in underground storage containers.

A number of electrical components arranged to provide power to charge the vehicle's power outlet,
Including an enclosure surrounding the electrical component;
The enclosure defines an extension post;
The post has an electrical outlet member at its upper end for supporting a receptacle for the electrical plug of the vehicle;
Here, the extension post is attached to a vertical sleeve member for vertical movement within the sleeve member from the retracted portion, where the post is in a deployed position within the sleeve member. Included, in its deployed position, the post stands up from the sleeve member and presents the user with the manipulated part of the contained part.

Including an enclosure surrounding the electrical component;
The enclosure defines an extension post;
The post has an electrical outlet member supporting a receptacle for an electrical plug of a vehicle at an upper end;
Here, the receptacle member forms a plurality of walls recessed inwardly from the panel, and the receptacle is attached to one of the walls inclined downward and inward from the top of the opening.

  The inclined walls can be positioned at an angle of approximately 45 degrees, but it should be appreciated that other similar angles can provide the same benefits. Installing electrical outlets at the 45 degree downfacing is primarily outdoors and in the rain and rain to protect the electrical outlet from direct weather without the use of an additional cover, which can be damaged over time. The goal is to achieve many advantages with respect to the use of.

The design includes the following features:
The receptacle member is installed with a waterproof wrap seal around the edge of the opening from the inside of the extrusion enclosure.
The receptacle member is installed without an external or visible fastening device.
The receptacle member positions the outlet at a 45 degree angle and raises it up and internally to protect it from rain and snow without the need for a moveable cover flap or the like.
The receptacle member provides weather protection to the three sides by being mounted within the enclosure.
The receptacle member provides a natural flow for the attached electrical cord in the lower position, which is gravity friendly.
The receptacle member is installed to ensure a smooth, unobstructed outer surface of the enclosure that allows for underground installation and is raised for the enclosure operation to be used.

According to a further aspect of the invention, a housing for an electrical component is provided, the housing comprising:
Including a plurality of extruded panels arranged in parallel for connection at the side edges,
The panels are connected by vertical joints at the side edges to form an enclosure defined by the panels for enclosing the electrical components;

It has a shoulder on its side, where the outer wall includes a cooperating shoulder and is flexible, thereby allowing the shoulder to pass.

  Thus, the engagement of the blade in the slot may be due to a snap action in the transverse direction rather than a sliding action in the longitudinal direction. However, it is not essential to provide a snap action that bends at the joint.

  Preferably, the outer wall is a joint for joining the retaining member and has a surface parallel to the outer surface of the first and second pusher members so that compression of the surface squeezes the blade member in the slot Acts as follows. This holds the blade in the slot and acts to prevent snapping from inadvertently opening the joint.

  Preferably, the outer wall has a thinner portion at the base of the slot and a wider portion at the end of the slot, the wider portion defining a shoulder. The thinner part allows bending. Thus, the extrusion can be formed from aluminum or similar relatively stiff material while still allowing a snap action.

  Preferably, the slot is inclined at an angle relative to the outer surface of the first and second pusher members at the joint. This insertion of the blade at an angle relative to the outer surface can be used to more effectively draw the outer surface to a plane containing the outer surface, because this is not the same angle as the insertion angle, and therefore the insertion is It is possible to accept the tolerance suitably.

  Preferably, an overlapping rib portion on one of the extrusion members at the outer surface is provided that engages on the other outer surface of the extrusion member in a recess at the outer surface.

  Preferably, a retaining member is provided for contacting the outer wall to prevent the outer wall from bending so that compression of the outer wall acts to squeeze the blade member in the slot.

  Preferably, the retaining member is supported on a bridge member extending to the joint and is carried by the first and second pushing members. However, it can be carried on other parts inside the joint.

  Preferably, the retaining member is a mounting screw and can therefore be adjusted to a position that engages the internal wall of the slot, although other parts can also be used.

  Preferably, a bridge member is provided for bridging the first and second extrusion members at the joint, each of the first and second extrusion members including a receptacle for receiving an insertion portion of the bridge member. Therefore, the bridge member bridges the joint inside the inner surface in order to prevent the joint from spreading.

  Preferably, the bridge member extends substantially along the entire length of the first and second pusher members and provides a holding force along the entire length. However, the bridging member can be formed, for example, in separate short pieces and only at the end of the joint.

  Preferably, the bridge member slides in a location along the first and second pusher members, thus acting to simulate a ziplock arrangement. However, it fits where the snapping action is preferably substantially perpendicular to the snapping action of the joint itself.

Preferably, the receptacles each form a slot that may be partially cylindrical.
Such a slot, which may be partially cylindrical, can be used to receive a screw inserted vertically into one end of the slot for fastening other parts such as the base or top wall.

  The bridging member may simply be additional support for the joint to increase resistance to the joint opening, but preferably the bridging member is against the parts located within the first and second pusher members. A support part is formed.

  Preferably, the first and second pusher members comprise two of a plurality of such pusher members, each of which is in the form of a male and female fastener, the first along the first side edge. Each has a cooperating connecting member and a second cooperating connecting member along the second side edge.

According to a further aspect of the invention, a joint is provided, the joint comprising:
A first extruded member having an outer surface, an inner surface and a first side edge;

Wherein the first connecting member includes a slot defined by an inner wall and an outer wall, and the second connecting member includes a blade member inserted into the slot;
Here, a 1st connection member contains the rib part which overlaps with the outer surface engaged on the edge part of the outer surface of a 2nd connection member.

According to a further aspect of the invention, a joint is provided, the joint comprising:
A first extruded member having an outer surface, an inner surface and a first side edge;

FIG. 24 is an isometric view of the housing of FIG. 19 installed on a sleeve member for vertical movement between a retracted position and a deployed position.

  In the drawings, like reference numerals indicate corresponding parts in the different views.

  The housing embodiments shown in FIGS. 4-18 are described in more detail below. These arrangements of the housing use the joint according to the invention shown in FIGS. This is between a first extruded member 10 having an outer surface 10A, an inner surface 10B and a first side edge 10C, and a second extruded member 11 having an outer surface 11A, an inner surface 11B and a second side edge 11C. Formed with. The first side edge 10C and the second side edge 11C are arranged to provide a cooperating connection for connecting the side edges of the members together to form a connection structure.

  The extruded member can be any structure, and typically includes a second side edge 10D on the member 10 for connection to the next extruded member, and a first side edge 11D on the member 11. Thus, each includes male and female side connectors at respective side edges. In this way, the member can be used to form a complete housing, or other structure of the connecting member with male and female connections, if desired.

  Members 10 and 11 are in a curved embodiment, such as being partially cylindrical, but other shapes may be used as described below. Members 10 and 11 have outer surfaces 10A, 11A that are corrugated to create an attractive appearance, although this is of course not a requirement.

  Members 10 and 11 are extruded to have a constant cross section along their length. The materials from which they are formed may vary depending on requirements, but are typically strong and rigid enough to form structural members such as housings, posts, etc. In such cases, aluminum, soft coated steel Or the use of metals such as stainless steel is preferred. As described below, the thickness and dimensions of the walls, as well as the snap fasteners to accommodate their function, can be selected by those skilled in the art using conventional knowledge.

  Thus, the first edge 10C has a first cooperating connecting member 20, and therefore the second edge 11C has a second cooperating connecting member 30, each of which has a respective first Extends along the first and second edges. Members 20 and 30 form a cooperating male-female connection whereby the first edge 10C is secured to the second edge 11C along the length of the edge.

  As best shown in the enlarged view of FIG. 3, the first connecting member 20 includes a slot 201 defined by an inner wall 202 and an outer wall 203. The second connecting member 30 includes a blade member 301 that is inserted into the slot 201 during the snap fixing operation.

  The blade member 301 is relatively stiff and is not intended to bend. The blade member 301 has an inclined road surface 303 that leads to a shoulder 302 on its side surface adjacent to the outer wall 203. The outer wall 203 includes cooperating shoulders 204 so that when installed, the shoulders hold the blades inserted into the slots against movement opposite to direction D so that the blades are inserted into the slots. It is usually engaged at an angle perpendicular to the direction D. To allow insertion, the wall 203 is flexible, and the walls that bend away from the blade when the shoulders 302 and 204 are pushed inward by the ramp surface 303 sliding over the entry surface 205 of the wall 203. Allows you to pass by 203.

  In order to allow the outer wall 203 to bend, the outer wall 203 has a thinner portion 206 at the proximal end 207 of the slot 201 and a wider portion 208 at the outer end of the slot 201 at the surface 205 and is wider. The part defines a shoulder 204.

  The slot 201 and the blade 301 are inclined at an angle A with respect to the plane P at the outer surfaces of the first and second pushing members at the joint. Angle A is approximately 30 degrees, but can be larger and can be as large as 45 degrees.

  The second connecting member 30 includes a second slot 304 that is arranged to receive the outer wall 202 of the first connecting member in parallel with the slot 201 in the first connecting member. Since the slots 304 are parallel to the slots 201, these slots define the direction of insertion D at an angle A with respect to the plane P.

  The first connecting member 20 includes a rib portion 209 that overlaps with the outer surface 10A that engages on the second outer surface 11A of the extruded member. To receive this rib portion and still provide an outer surface that is horizontal or close at the junction between surfaces 10A and 11A, surface 11A includes a recess 305 that coincides with the rib. Both the recess 305 and the rib 209 include a side surface 210 that is parallel to the plane P, so that the insertion of the overlapping rib portion 209 into the recess 305 is parallel to the plane P and the outer surface at the joint.

The application of the tilt angle A for a state that is simply straight and groove is as follows:
a) In order for the joints to fail and the joints to fall apart, the extruding members move away from each other in two directions rather than just apart from each other, but if one moves down, the other moves up Necessary.
b) Similarly, the idea of having a tilt angle increases the surface area of the joint, thereby resulting in a stronger joint.
c) The increased surface area of the connecting joint increases the water resistance of the joint due to possible flow rates, increased distance, and opposing angles that water would have to travel to damage the joint.
d) Also, in the joint assembly, visualizing a rigid joint is easier because one extrusion is placed higher than the other if the joint is not properly connected.

  Since the snap action connecting the connecting members 20 and 30 is based on the bending of the thinner portion 206 of the wall 203, it can be locked by providing a retaining member 401 of the bridge member 40. The retaining member 401 is a mounting screw having a head 402 and a front surface 403 for contacting the outer wall 203 to prevent the outer wall from bending, so that compression of the outer wall 203 causes the blade 201 in the slot 201 to be compressed. The member 301 is squeezed and acts to prevent the blade from being pulled out of the slot by engagement of the shoulders 204 and 302. For this purpose, the outer wall 203 at the wider portion 208 includes a surface 211 that is parallel to the plane P and hence the outer wall, and therefore joins horizontally to the front surface 403 of the screw 401.

  The bridge member 40 extends into the joint and is carried by the first and second pusher members at their respective ends. Accordingly, the first and second pusher members 10, 11 each include receptacles 10E, 11E for receiving bridge member inserts 404, 405, so that the bridge members are constrained from spreading the joint. Bridge joints inside the inner surface. Each receptacle 10E, 11E forms a partially cylindrical slot with a partially cylindrical inner wall 10F and an opening 10G narrower than the wall. The insert includes a neck 407 and a compressible bead 408 that can be pinched into the receptacle by compression of the bead so that the outer surface of the bead coincides with the cylindrical surface 10F. The bridge member can extend substantially along the entire length of the first and second pusher members and can slide to a location along the first and second pusher members. The neck 407 usually extends at a right angle to the surface or plane P, so that the tension that tends to allow the joint to split is transmitted through the bridge member itself, at a right angle to the neck. As a result, the bridge member resists the movement of the joint away and therefore acts as a lock. The bridging member extends along the joint near the inner surface of the joint at the wall 203 and thus provides a joint support without significantly disturbing the area inside the structure. The bridge member includes a longitudinal slot 409 having a mouth 410 and a partially cylindrical receptacle 411 for attaching components within the structure.

  Each of receptacles 10E, 11E, and 409 is of a type that can receive a screw fastener that is engaged to the end of a partial cylindrical wall that is vertically inserted into one end of the slot.

  The bridge member 40 is also for components positioned in the panel using mounting pins 416 supported on the member 40, as shown in FIG. 1, or by other mounting elements using, for example, receptacles 409. Can also be used to form the support 415.

  Referring now to the housing structure for electrical components formed using the panel and joint structure described above and shown in further figures, particularly in FIG. A structure for attachment is shown (not shown). The structure includes a concrete base 52 and a cylindrical upstanding portion 51 defined by a footing portion 50. These are typically mounted in or on the ground as a structural foundation for the housing structure, and can be any shape or arrangement depending on the number of housings mounted and the terrain to which they are mounted.

  The housing structure includes a post 60 and an upper receptacle compartment 70 attached to the portion 51. The electrical component can be attached to one or both of the post and the receptacle, depending on the structure and size of the component. Typically, the power source and optionally the communication cable enter a post for providing electrical components through the base 52.

  Post 60 includes a plurality of extruded panels 10 and 11 connected by joints at edges 10C and 11C. The bridge member 40 extends over the joint. All these parts are the structures described above and need not be repeated here. Thus, each of the panels includes a male connection member 30 along the first side edge and a female connection along the second side edge for connecting the male member with the female member as previously described. The member 20 is included. Thus, the male connection member provides snap fastening to the female connection member by being inserted in the direction of the blade 301 into the slot 201 at right angles to the ends to form a joint therebetween. Thus, the panels 10 and 11 cooperate to form a cylindrical enclosure that forms a post defined by the panel for enclosing the electrical components.

  Each joint is provided with a respective one of a plurality of bridge members 40, each of which bridges the panels with a respective one of the joints between the panels. Each of the panels includes receptacles 10E, 11E for receiving the inserts 404, 405 of the bridge member 40 so that the bridge member bridges the joint inside the inner surface of the housing to prevent the joint from spreading. Join. The bridge member 40 extends along the entire length of the panels 10 and 11 and slides to a location along the panel.

  The post 60 further includes a bottom end plate 601 and a top end plate 602 at right angles to the panel, as best shown in FIG. Each bridge member connects at one end to the support member or plate 601 and at the other end to a plate 602 that normally extends at a right angle to the panel to provide a connection between the panel and the support member or plate 601, 602. Is done. Thus, the plate and bridge member form a structural member for holding the panels 10, 11 in place.

Each plate 601, 602 is recessed on a surface that receives the bridge member and includes a recess 603 shaped to coincide with the inner surface of the bridge member 40 with a receptacle 409 therein.
Therefore, the end face of the bridge member is located in the recess 603, and the recess prevents movement with respect to the end plate. The bridge member is secured to the plate by a screw 604 engaged in the recess 603 through a hole 605 in the end plate, which screw is adapted to tighten the bridge member against the end plate as Engage with the end of the partially cylindrical receptacle 409.

  Thus, the bridge member is connected at each end to each one of two end support members that typically extend at a right angle to the panel so that the two end support members and the bridge member are within the panel. A support structure is formed. The panels are then connected on the outside of this structure by engaging their joints and by attaching a bridge member, so that the connected panels slide along the support structure. End plates 601 and 602 have a central hole 606 that allows insertion of electrical components and / or connection leads.

  The bottom plate 601 is secured to the part 51 by suitable fasteners (not shown). The upper plate forms a support for the base 701 of the receptacle 70.

In FIG. 14, the receptacle 70 is relatively small and is formed by two panels 702 and 703 connected by edge connection joints 20 and 30 as previously described. Additional panels in the method of FIG. 4 may also be provided depending on the required receptacle size. The bottom plate 701 is formed in two portions 706 and 706 having holes 707 connected by edge connectors 20 and 30 as previously described. The bottom plate is secured to the panels 702 and 703 by screws extending through the plate to the ends of the receptacles 10E and 11E (FIG. 3).
The top plate 704 is formed in one and forms a closed top (not shown) secured to the panels 702 and 703 by screws. Each of panels 702 and 703 includes a hole 709 through its wall for access to the interior so that an electrical outlet of a conventional structure is mounted in the wall to allow plug connection from a vehicle or the like. The electrical connections to the internal electrical components can enter the interior through the wall, and in this embodiment most electrical components are housed in that state, and the upper receptacle is primarily simply a support for the electrical outlet. Part.

  In FIG. 15, a similar arrangement is provided in which a base 52, post 60 and receptacle 80 are provided. In this case, the receptacle is quite large and is intended to include all electrical components. In this case, the receptacle is formed from panels 801 and 802 and a top plate 803, all of which form a normal right angle structure with vertical sides. Panel 801 is curved to form the corners of the receptacle. Panel 802 is flat and includes holes 804 and 805 for electrical outlets. In this arrangement, the bridge member 40 is omitted from the receptacle, and fixation to the top and bottom plates of the panel is achieved only by insertion of screws 806 into the receptacles 10E, 11E.

  Referring now to FIG. 16, there is shown a further arrangement of receptacles 90 that can be mounted on a post or directly with a ground base. The base plate 901 and the upper plate 904 are connected to the flat panel 902 having the holes 913 and the corner panel 903 in the manner described previously.

  In this embodiment, a cover plate 905 mounted on top plate 904 and spaced from spacer panels 906 and 907 around the edges is provided. Panels 906 and 907 conform in shape to panels 902 and 903 and are attached in a similar manner. The cooling duct 915 extends through the receptacle 90 from the bottom hole 912 in the plate 901 to the top hole 914 in the plate 904. The cooling duct is formed from two connected panels 909 and 909 using a joint 916 and a receptacle 911 as previously described. The surfaces of panels 908 and 909 support cooling fins 910. These extend outward from the surface of the respective panel and can protrude into or out of the duct 915, but preferably extend inward to fit the air passage through the duct. The airflow is caused by convection and enters the duct through the bottom hole 912, exits the duct through the top hole 914, and enters the area between the top plate 904 and the cover plate 905. Panel 906 has a hole that allows air to exit. Thus, the panel can be used to achieve cooling of electrical components at locations where significant outside air heat can cause overheating. Thus, in this embodiment, panels 908 and 909 are arranged so that the cooling fins form a cooling duct on the inside of the housing.

  As shown in FIG. 10, at least one of the panels supports a plurality of cooling fins 120 on the exterior generally extending outwardly therefrom.

  As shown in FIGS. 12 and 13, some of the panels 130 and 140 are shaped to be generally concave to form an internal corner defining a recess 141 having a hole 142 for attachment of a receptacle. It is. Thus, the hole 142 is not only protected in the recess and provided on the outside on the outside, as previously described. This allows protection of the hole by the cover 143 and the sliding front panel 144. Both cover 143 and panel 144 have edge beads 145 attached to receptacles 146 on panels 130 and 140, thus defining an external slot that receives the edge of the slidable exterior panel.

  As shown in FIGS. 4-12, the housing includes panels of different cross sections. Thus, as shown in FIG. 4, some of the panels 190 are generally straight or flat in cross section and some 191 form corners. A short connector panel 192 may also be provided.

  Thus, as shown in FIG. 5, some of the panels 193 define a flat plate 194 having connectors 20 and 30 that extend perpendicular to the rear surface of the flat panel.

  In FIG. 6, a T-shaped cross section is formed using a flat panel 190, a partial cylindrical panel 197 and an inverted panel 198.

  In FIG. 7, the hexagonal cross section is formed using a flat panel 190 and a short 60 degree connector panel 198.

  In FIG. 8, an annular cross section is formed using four partial cylindrical panels 197.

  In FIG. 9, a D-shaped cross section is formed using a partial cylindrical panel 197 and a flat plate panel 193.

  In FIG. 10, an elliptical cross section is formed using a partial cylindrical panel 197 and a short connector panel 198.

  In FIG. 11, the triangular cross section is formed using a straight panel 190 and a short connector panel 198.

  This structure forming a different cross section is achieved because each male connecting member of the panel has the same cross section and each female connecting member of the panel also has the same cross section.

  FIG. 18 shows a modification of the arrangement of FIG. 17 in which the recess 621 relative to the end of the bridge member 40 is spaced inwardly from the outer edge 624 of the plate 620, resulting in panels 10 and 11 (shown in this view). Is not located on the outer periphery of the plate than it is located on the outside of the plate as in FIG. Thus, the plate 620 completely closes the end of the housing.

  Referring now to FIGS. 19-24, a further embodiment is shown that includes a right angle post 200 with a top cap 201 and a bottom cap 202. The post is formed from a plurality of panels 203 of the previously described structure so that all previously described features are incorporated herein as the structure of post 200 or an optional arrangement therefor. Thus, the housing or post 200 includes a top cap portion 205 for engaging the top edge of the panel, and a bottom end cap portion 206 that is applied over the top cap portion 205. The post includes a lower end cap 202 for engaging the bottom edge of the panel 203.

  The top cap 201 and the bottom end cap 202 are identical in the structure and each includes an edge and an edge to form a peripheral member shaped and arranged to receive the edge of the end of the panel 203. Are divided into sections 207 and 208 (FIG. 20) which are connected together. Thus, each compartment has the same shape in plan with each panel to match and receive the panel above it. That is, each compartment receives a respective one edge of the panel. Thus, in the example where the post is perpendicular in cross section, the post is formed with two separate half channel shapes connected by a joint 210 along the side surface 211 of the post. Similarly, the end cap is formed in two separate half U-shapes connected to the side lap joint 213 as shown in FIG. The lap joint 213 forms a rib insert 214 on the end of one compartment 207 that slides horizontally and perpendicularly to the side to a channel receptacle 215 on the end of the compartment 208. Thus, caps 201 and 202 are formed separately from the panel so that the end caps for the rings for engaging the respective ends of the assembled tube are defined by the connected panels. Due to the different forms of assembly provided by the panel snap connection and the end cap lap joint, they cannot be connected or disconnected from the panel attached to the end cap.

  Each end cap is horizontal with an outermost dependent vertical surface wall 217 around the outer edge of the receiving wall and an upright interiorly located wall 218 for engaging and positioning the inner edge 219 of the panel. Receiving receiving wall 216 can be included. Thus, the top cap has a lower surface 220 of the wall 216, to which the panel is bonded, and the lower cap has an upper surface 221 on which the panel is located. The bottom edge 223 of the wall 217 has a lip 224 around its outer edge. The lip 224 functions as a draining shelf for the top cap that prevents water from flowing onto the enclosure and to the sides of the enclosure, but instead the water becomes polka dots and triggers to fall to the ground at the edges. At the bottom edge, the lip 224 functions as a seal to the mounting surface where the lip is positioned to ensure an interference fit along the bottom of the enclosure. The lip is the weakest point along the bottom surface, thereby obeying an uneven mounting surface that produces a better seal. Wall 216 has a raised insert 246 on its upper surface for engaging channel 1E, as previously described to position the panel on the upper surface of the end cap. To support. A fastener screw (not shown) can be inserted in this position to hold the panel in place and cap the end of the panel. The interior of the end cap member includes a mounting connection as shown at 248 for the inner part of the housing, which can of course vary depending on the requirements.

  This dynamic flexibility is due to the extrusion itself of the panel 103, such as consisting of interconnecting male and female sides, allowing the end caps to be interconnected in any shape and size that can be matched. Achieved in the same way. This allows easy production and allows the base and top cap to match any design of the extrusion enclosure that is tailored to the dynamic nature of the extrusion enclosure concept.

  Lap joints 214, 215 act by sliding together to create a lap joint that prevents water from passing through the joint and entering the enclosure.

  In FIGS. 19, 21 and 24, an enclosure is shown that encloses an electrical output for plugging a vehicle for charging, or other power supply as required. The enclosure provides an extension post 200 where the extension post is driven by a suitable drive mechanism 247 such as a cylinder or a linear motor in a sleeve member from a retracted position (not shown). Attached to the vertical sleeve member 225 for 226 and in its retracted position, the post is included in a deployed position in the sleeve member 225 having an upper cap 201 on top of the sleeve member 225, and in its deployed position. The post stands up 200 from the sleeve member 225 and presents the operating components of the contained components to the user. The sleeve member 225 can be mounted underground, so that the post is retracted underground such that its top plate is on the ground surface, or the sleeve member provides a protection against the post 200, such as a concrete post. A solid member extending from can be formed.

  The post has an electrical outlet member 226 with an opening 227 for supporting a receptacle (not shown) for a vehicle electrical plug at the upper end.

  The electrical outlet member 226 forms a plurality of walls 229 and 230 and side walls 231 that are recessed inwardly from the outer surface of the post 200. Walls 229, 230, and 231 are supported on a plate 232 that is affixed on the inner surface of panel 233 with a flat front surface 234 of the post at opening 235 in front surface 234. The receptacle 228 is attached to one of the walls 230 of the electrical outlet member 226 that is tilted downward and inwardly from the upper edge 236 of the opening 235 in the front surface 234. The walls 230 are arranged at a 45 degree angle. Installing electrical outlets on the 45-degree lower surface in the receptacle is primarily for outdoor and rain to protect the electrical outlet from direct weather without the use of additional flaps or covers, which can be time damaging. The goal is to achieve a number of advantages with respect to its use.

  Plate 232 is installed without an external or visible fastening device with a waterproof wrap seal around the edge of the opening from the inside of the extrusion enclosure.

  Various modifications may be made in the invention as described hereinabove, and similar and distinctly different embodiments may be made within the spirit and scope of the claims without departing from such spirit and scope. It is intended that all matter contained in the accompanying specification be interpreted as illustrative only and not in a limiting sense.
