When even the dog is panting

Clever inventions to combat the heat

When the temperatures rise in summer, sometimes there's only one thing to do: seek shade - just like our four-legged friend has been doing for a long time. But if you don't want to spend the whole day sweating under a parasol next to your dog, you need some clever solutions to cool you down. Fortunately, there are clever people who keep a cool head even on hot days - and have their inventions protected by the German Patent and Trade Mark Office. This is particularly quick and uncomplicated with the utility model - an efficient protection option for technical inventions. This property right is ideal for inventions that need to be brought to market as quickly as possible. Effective protection can be applied for in a short time without a lengthy examination procedure. We have fished out some practical utility models from the archive that show how imaginative dealing with summer heat can be: from the spaghetti ice cream machine to the floating villa and the sunlight-reflecting building façade.

Fancy a few refreshing insights? Here they are.
You can find these and many more utility models in DPMAregister.
