Heavy-duty Latches Ensure Secure Storage on the Road

Wednesday, March 28, 2012 by Daniel McCourt

 

Utility VanThe utility van: mobile office for the construction industry. For contractors working out of their vans, storage plays a key role in their daily operations. If tools and materials are not securely stored, contractors could face damage to their van and tools, as well as potential  injury caused by unsecured objects. 
 
A vehicle utility contractor for a large electricity company recently approached Southco engineers regarding a latching system to secure wall-mounted storage compartments and cabinets inside its fleet of utility service vans. The company had received reports from its employees that the existing hardware was sometimes unpredictable in its operation, resulting in tools popping out of boxes while the vehicle was in motion.
 
The contractor was seeking a strong, durable latch that would stay closed when disturbed by bumps and turns while the van was in motion, as well as exposure to changing weather conditions, since the rear door of the van would be frequently opened and closed by the technician when on the job.
 
Our engineers recommended Southco’s Stainless Steel R4-10 Rotary Latch, which brings corrosion-resistant strength to a proven latching 

solution that delivers long lasting durability and security to heavy-duty 
applications. For this application, our engineers recommended combining the R4-10 with Southco’s AC-70 Single Point Paddle Actuator for a complete latching solution. When installed, the R4-10 is linked to the Actuator by a cable, which triggers the latch when the Actuator is engaged. Additionally, the AC-70’s low-protrusion, front-mount design allows for easy operation by the end user, who need only actuate the paddle with the pull of a finger.
 
With a simple push-to-close operation, the R4-10’s concealed latch accommodates misalignment between the latch and striker bolt, making it suitable for a wide variety of applications. In gasketed applications, a double stage latching option provides additional security and functionality, allowing the user to push the door once to keep it closed, and push it a second time to securely latch it, preventing a false latching condition which could result in the door opening accidentally.
 
Are you facing a challenging application that calls for a more robust latching solution or want to know more about our rotary latches or hinges? Tell us in the comments.
 

“Hooked” on Interior Railway Design Upgrades

Tuesday, February 14, 2012 by Daniel McCourt
“If the cost of gas goes any higher, I’m taking the train.” Sound familiar? It’s no secret that the ever-rising cost of gas is forcing many commuters to abandon their normal car ride to work and opt for public transportation instead.  In answer, many railway Taking the traincompanies are taking increased ridership by the horns, and making design upgrades to their heavily used railcars.

We recently had a conversation with an engineer who was tasked with redesigning the interior of a local transit company’s  existing railcar. The transit company had requested the engineer to incorporate suggestions obtained through a commuter survey into the design, including improvements to hinges, locking mechanisms embedded in seating.  Of the commuters who provided feedback, a significant number were concerned about having a place to hang their coats, bags and personal belongings during overcrowded peak hours.

Specifically, the engineer was seeking a safe way in which to incorporate coat hooks. In the traditional rail car design, a multi-pronged coat hook protruded from the center of the outer seat panel into the walkway, and often into people forced to stand during peak commuting hours. The challenge was replacing this outdated and potentially dangerous design with something that was both safe and functional.
Southco Coat hook
Our experts suggested Southco’s MP Coat Hook, which remains flush when not in use, and deploys an inner latch, releasing pop-out hook with just the push of a button. It’s ability to remain flush when unused frees up more space, allowing for multiple installations should the design require it. The MP is available with several flange shapes with multiple chrome- or brass-plated finishes to match the stylish new interiors of many mass transportation vehicles – including not only railcars, but buses and airplanes as well.

How will the growth of commuting impact mass transit interior design? Or have an application for a compression latch or position contol hinge you would like to discuss?  Tell us in the comments.

Multi-Point Latching Goes to Great Lengths for Enclosure Cabinet Security

Thursday, February 2, 2012 by Daniel McCourt
Datacenter DesignData center engineers dedicate sizeable amounts of time to designing enclosures, which includes specifying cabinet storage that will ultimately house the complete system.  Factors such as size, materials, rack dimensions, security,  heating and cooling options and the costs associated are all considered by engineers throughout the design, but when it comes to accessibility, it sometimes isn’t approached until the very end of the design process.

We recently had an engineering firm come to us late in the design process with a need to incorporate a multi-point locking system into a tall, upright enclosure door design. The cabinet required a latch that would securely lock its entire length with only one turn. The firm also requested that the system take up minimal space in the overall cabinet design.

Southco engineers suggested one, three-point H3 Swinghandle Multi-point System to secureH3 Swinghandle the enclosure door. When installed, the Swinghandle, which nests into its housing with minimal protrusion, sits on the outside of the cabinet door, and pops up to swing smoothly for easy latch actuation. The cam mechanism sits on the inside of the enclosure door, and a series of rods that run up the entire length of the door are activated by a linear actuator, releasing the latch when the Swinghandle is rotated.

Southco’s H3 is available with multiple offset cams, multi-point latching, and numerous locking and non-locking options that simplify cost-effective configuration. Available in lightweight, robust nylon or heavy-duty die-cast, the H3 is suitable for indoor enclosure cabinet applications across industries.

What types of challenges have you experienced in your enclosure design? Or do you have an application question about latches, hinges or captive fasteners? Tell us in the comments.

Ten questions to ask when designing in a hinge

Thursday, October 13, 2011 by Daniel McCourt
Part 10 in a 10-part series on specifying hinges

checklistWe spent the last several weeks discussing different factors for specifying hinges. After all, incorporating hinges early into designs helps keep costs down and options open. So here, for your reference, is a quick summary of questions to ask in the early stages of your application. They will save you time, money and maybe even a bit of frustration!
  1. How much load must the hinge withstand? Determine the size, weight, and center of gravity of the door.
  2. How do hinges fit in the overall design? Designing the hinge in early may allow use of an available hinge.
  3. How much space can you afford inside or outside the enclosure? This may help you decide between concealed and externally mounted hinges.
  4. How do you plan to mount or access the door? Door and frame configurations play a critical role!
  5. How far must the door open? Detent and friction hinges will keep a door open without secondary mechanical supports.
  6. Is removing the door a requirement? Lift-off hinges enable fast door removal.
  7. What specifications must the hinge and enclosure meet? Many hinges are certified to meet various industry standard specifications.
  8. How will the hinge be installed? Consider the manufacturing and installation process carefully.
  9. Do you need to meet specific material requirements? Think about environmental conditions the end product may face.
  10.  How large a role do aesthetics play in the design? Balance performance needs with style and appearance.
To learn more about any of these topics, please see the past weeks’ blog entries, which discuss each of these questions in greater detail. Or contact us personally. We'd love your feedback and questions.

Design guyOkay, so you’re looking to optimize the overall quality and cost effectiveness of your application. When it comes to hinges, it is important to balance performance needs with aesthetic judgment. Looks DO matter and can greatly influence a product’s overall look and perception of quality.

Large, external hinges give an impression of great strength whileDetent hingeFriction hinge concealed hinges can increase security or create a streamlined look. To further enhance an application’s design, we often have the option of customizing plastic and powder-coated hinges to suit specific color specifications. Some hinges even include snap-on covers to conceal mounting hardware and create and more polished appearance. Even the mounting hardware can be concealed by installing the hinge from the back side of the door.

Stainless Steel HingePolished hingeWhether you want polished and sleek or sturdy and strong, there is a hinge that will convey the appearance you seek and contribute to the overall aesthetic of your application.

Hinges and Material Requirements

Wednesday, September 21, 2011 by Daniel McCourt
Part 8 in a 10-part series on specifying hinges

Sheet_metalThere are many factors to consider when selecting a hinge. We have discussed opening angle, frame configuration, industry specs and installation method, among others. But a critical consideration not to be overlooked may seem like the simplest: material.

When deciding between material options, be sure to consider not only the end uszinc torque hingee but alsostainless steel hinge environmental conditions. Factors from temperature range and chemical exposure to UV radiation and moisture conditions can (and should) influence our choices. As you well know, hinges comes in a variety of materials such as steel, stainless steel, die-cast zinc and engineering plastics. Each of these materials brings with it certain great benefits.
Plastic Hingestainless steel lift off hinge
Steel and stainless steel hinges withstand temperature variations, and engineering plastics and stainless steel offer corrosion resistance. Need reduced noise and vibration? Consider a plastic hinge. Whatever your need or application, there is a hinge material perfectly suited to it. Need help finding one? Contact Southco or share your thoughts on this discussion.

Hinges and Installation Method

Friday, September 16, 2011 by Daniel McCourt

 Part 7 in a 10-part series on specifying hinges

InstallationThe method of installation is an often overlooked consideration when selecting a hinge. Manufacturing tolerances in the design and installation process can impact our hinge specifications, especially where aligning the hinges on the door and frame are concerned. Slotted holes may help compensate for manufacturing variations.

An important questions that we have to ask is: Where in the manufacturing process is the hinge installed? This may have a profound impact on hinge selection. It’s helpful to determine whether the leaves will be assembled to the door and frame at the same time or in different locations and assembled later. Mounting methods run the gamut and include screws, studs, rivets, welds and adhesives.

Lastly, you want to determine clearance for any tools needed for installation (as well as the hardware itself).  Most of us have found ourselves in this unfortunate situation at least once! So don’t get stuck at the end. Figure this out early and save yourself time and aggravation.

standardsSelecting the proper hinge can sometimes be more challenging that we might expect. In addition to considering cost, aesthetics, strength requirements and door configurations, we need to also consider any regulations or specifications that might affect our applications. 

For example, hinges used on outdoor enclosures housing electronic equipment may be required to meet NEMA and IP standards. Is your application in the food equipment industry? NSF certification imposes stringent guidelines on materials and design.
southco hinges
Specs may require evaluation of an entire system, or hinges may be certified to meet a spec as-is. Either way, you want to select a hinge capable of meeting all product standards.

A keen understanding of industry requirements will help you select the best hinge for your application (and will save you time and money in the process!).

Removable hinges and interior access

Thursday, August 18, 2011 by Daniel McCourt


Part 5 in a 10-part series on specifying hinges

ServicemanSometimes a user or service technician requires full access to the interior of a cabinet or enclosure. If this is the case,  lift-off hinges or hinges with retractable pins can make it quick and easy to remove a door. You’ll also find these hinges valuable if a product ships unassembled or if the door and frame are manufactured in different locations.

Lift-off hinges let you remove the door in a single motion (withoutLift Off Hinge using tools). Just lift the door off the hinge pins mounted to the frame, and replace it by lowering it back over the hinge pins. Both your hands will remain free to maneuver the door. It might be a two-person job at most, but you’ll be amazed at the ease and speed of removal these hinges allow.
 
Hinges with retractable pins enable door removal without ever having to lift it. You retract the hinge pins and pull the door straight off. To replace it, you would just need to align the two halves of the hinge, Pin Lift Off Hingeextend the pins and lock the door back into place. Quick and very simple. While hinges with pins permanently attached won’t let the hinges drop or get lost, retractable hinge pings might be a better choice if the hinge axis is not guaranteed to remain vertical and steady.

Considering the opening angle: Detent and torque hinges

Monday, August 15, 2011 by Daniel McCourt

Part 4 in a 10-part series on specifying hinges

Door StayWe have all been there: Trying to keep a door open with our foot, a shoe or something else we find lying around. Today’s applications increasingly require hands–free access (or a really patient friend who will hold the door for you). If this is the case with your application, consider using a hinge with a built-in detent feature to hold the door  or panel open at a preset angle. Or use an adjustable-torque feature, which will let you tighten or free up the door swing. Both of these hinge styles eliminate mechanical supports like gas struts or door stays.

Detent and torque hinges are two products in one—the hinge and the doorDetent Hinge stay. They bring with them some nice benefits, too. They reduce the number of parts, cut down on installation time and lower the overall cost.

Most detent hinges come with preset opening angles; some even provide negative angles that let the hinge go slightly past center when closed. This also holds the door securely against the frame and Torque Hingereduces vibration (a viable option when you know you might have rattling!). In some cases, you won’t even need a latch. Detent hinges are most appropriate for small lightweight applications. If this sounds like your application and you can benefit from some of these features, give it a try!

Deciding between concealed and externally mounted hinges

Friday, July 29, 2011 by Daniel McCourt
Part 3 in a 10-part series on specifying hinges

Access PanelWe’ve discussed how important a consideration strength is when selecting a hinge. Now it’s time to examine the design considerations that sometimes dictate whether we select a concealed or externally mounted hinge.

Concealed hinges mount on the interior part of the door and frame. They are great to use when you desire a clean outer panel (and you get the added benefit of vandal resistance). When using an internal hinge, just remember to consider the amount of internal protrusion since inside space may be limited. These hinges may also restrict access and make it hard to install and hide mounting hardware. Since they work with specific doors and frames, product and mounting options should be designed with them in mind. Used appropriately, internal hinges deliver a sleek, streamlined appearance.Stainless Steel Lift Off HInge

Exposed, external hinges deliver a different set of benefits: they work with limited interior space, offer greater strength and allow for a greater door-opening angle. Unlike concealed hinges, they are easy to fit to an application anytime in the design process…and they are more universal. They of course won’t be hidden, so care should be taken to blend the hinge design with the application.

How strong of a hinge do you really need?

Tuesday, July 19, 2011 by Daniel McCourt
Part 2 in a 10-part series on specifying hinges

Stong ManLast week we discussed how strength is often one of the first considerations when choosing a hinge. But just how strong a hinge do you need?

Here at Southco we use four factors that can help when getting started.

1. Weight: Determine the weight of the door. If you can’t physically weigh the door on a scale, a quick estimate can be calculated with the following formula: length x width x height x density. The heavier the door, the stronger the hinge you will need.

2. Center of Gravity: Determine the center of gravity (Cg) of the door. If the door is uniformly thick, the Cg will lie dead center. Unfortunately, most doors aren’t uniform.

So here’s a few simple steps for determining the Cg, regardless of door shape.

(A) Hang the door from one corner so it pivots freely Hinges
(B) Attach a plumb line to the pivot so the line hangs freely
(C) Mark the line on the door
(D) Repeat twice more, hanging the door from a different corner each time

The Cg is where all three lines intersect.

3. External Loads: Consider the added weight of components that might be fastened to the door: electronics, cooling equipment, hooks, etc. And don’t forget loads applied by wind, moving objects or forces generated by gasket compression or pressure within an enclosure.

4. Test:  Whenever possible, test the hinge in the application. Variations in mounting and build tolerances often mean that one hinge takes the brunt of the load. We need each hinge to share equally in the effort!

Next week: Considering overall design and deciding between concealed and externally mounted hinges.

Incorporate hinges early to save money and frustration

Tuesday, July 12, 2011 by Daniel McCourt
Part 1 in a 10-part series on specifying hinges

External HingesIt is not uncommon to wait until the last minute to incorporate hinges into a design.  We know that not everyone has hinges at the top of their list of important things to think of when working on a new car, enclosure, or life-saving medical device.. However, considering hinges late in the design cycle can limit your options. You might have to compromise your design or force nonstandard parts into your product risking increased cost and reduced performance.

Over the next 10 weeks, we will examine multiple factors to consider when specifying hinges. Keep these tips in mind, and you’ll keep your options open (and your project costs down).


Let’s start with one of the first considerations when it comes to hinges: strength.

StrengthHow much load will the hinges bear?  And many times it’s not just the weight of a door but all external sources of load. Will equipment be mounted on the door? Make sure to account for dynamic loading.

Another tip to keep in mind: the as the ratio of door width to height increases, so too do the stresses. For maximum strength, place hinges as far apart as possible on the longest edge of the door. Or, depending on the design, use a closer hinge spacing to stiffen the door or ensure sealing against a gasket.


Next week: How strong a hinge is needed? I’ll share four specific factors (and a handy formula) to help you out.

2010 WindPower Conference & Exhibition Blog

Thursday, July 15, 2010 by Maureen Donovan

Wind Energy… Firmly entrenched in Europe wind energy is an exciting opportunity for North America and beyond.  And boy, did the 2010 Wind Power Show in Dallas indicate that.  Over 20,000 attendees and nearly 1400 exhibitors representing companies from countries all over the world including Germany, Spain, Italy, India, Canada, China, Korea and many others.  And the diversity of the offerings was immense… from the largest wind turbines you have ever seen, to the ladders and hoists that allow access and service, to the components inside the turbine that control pitch, power conversion, etc, to the trucking and transport companies responsible for transporting these large turbines and blades across the country.

The excitement at the show was evident, the buzz non-stop.  People are really excited about wind energy taking off in North America.  According to the AWEA, last year the United States installed more than 10,000MW of new wind power.  Thirty six states now have wind projects.  The people were a friendly bunch… happy to discuss opportunities knowing that  we all must all work together to grow this market, both for our companies and the environment.

So let’s talk about the exhibitors.  The turbines are unbelievably large.  Anyone who has ever seen a wind turbine across a field has little idea of the magnitude of these structures.  Or of a single blade.  Or of  the nacelle.  These structures make people look like ants!  All of the major manufacturers were there and it was impressive group.

One of the discussions we had with several of the global exhibitors is the necessity to have local manufacturing around the globe.  It is not economically feasible to ship these large parts all over the world.  Rather the large turbine and blade manufacturers must set up shop regionally, and thus need local suppliers in each region.

Of particular interest to Southco, were the many exhibitors who manufactured equipment for the inside of the turbine.  Many latches, hinges and fasteners could be found on the pitch drives, the inverters and other enclosures in the turbine.   There are a lot pieces of equipment  that need to be accessed during service, and our quarter turn fasteners and compression latches fit the bill..  There are also a lot of applications on the testing equipment, whether it is for monitoring the amount of wind at a location or testing the systems  in the wind turbine.

Other than that there was a lot of just plain fun.  A delicious exhibitor-sponsored lunch was provided each day and offered a good opportunity for networking.  There were plenty of evening activities including a function at the Hard Rock Café featuring Elvis Costello and the Conference Dinner starring Sienfeld’s Jason Alexander.  Even some of the booths got into the spirit of things… The Wind Energy TechnoCentre of Quebec  hired a three-piece Texas jazz band to perform at the end of the day, which led to quite a lively happy hour!

Bottom line is that it is an exciting time for green energy worldwide and especially wind. 
The growth potential is enormous and the clean energy it can provide is ELECTRIFYING!
