What was the original? The history of jumpers or rebound shoes
The true history goes beyond the propaganda of brands. There has been an evolution for more than 100 years until reaching the most advanced model today, which is the Aerower Jumper1. In this post I will review the history that goes beyond Kangoo Jumps and Exerlopers.
The history is much longer than you think.
You can call them bouncing shoes, jumping shoes, rebound shoes or jumpers, but the idea is the same, a type of footwear that helps to jump, cushion the jump or bounce. Many people believe that I was the inventor because of my 20-year career developing the Kangoo Jumps and, recently, the Aerower, but the jumpers already existed before. Kangoo Jumps practically copied an earlier little-known model, the Exerlopers,(1) and my job, since I started developing this product at KJ in 1998, was precisely to make it technically and commercially viable. However, in my research, I was able to verify that even the Exerlopers were not the original ones(2) . There has been an evolution for more than 100 years until reaching the most advanced model today, which are the Aerower Jumper1(3) % uFEFF .
I must admit that the launch of Aerower has not been without attempts by KJ to threaten, prosecute and slander. Aerower is the only company that is innovating in this sector and has been successful in everything because it has its own developments. Along the way KJ has lost the 3D brand registration and monopoly privileges. There are still people who believe what KJ says, that of "trust the original" or that of being a bad copy when the designer and technical director of both KJ for 17 years and Aerower: Carlos Peydró(4) My maximum interest has always been to improve both the product and the experience of this activity beyond egos and personal interests.
When do you think the first jumpers were invented?
It is easy to imagine that man, since he is able to create tools to facilitate hunting and harvest, has tried on many occasions to improve his movement limitations. The human being invented footwear, stilts, saddles, wheel, etc. and, I am sure, that the idea of improving the jump with some type of spring on the feet has been imagined since it was discovered some type of spring. That said, I don't think we ever know when, what was or who created the first shoe to jump more and better.
We can get to the idea that at some point we use branches, as some animals do to propel themselves, but that is not the same as wearing a spring system on the feet. In the collective imagination are shoes with springs such as those of Inspector Gadget, Gyro Gearloose and those that appear in so many comics for children or the powers of and some superheroes.
Our ancestors must not have always given up something, as fun as jumping, solely because of growing up. Sure not! Branches, wooden planks, rope bridges, hay bales, swings, the modern static bed or the simple act of riding for pleasure, have been used for the fun that occurs when we feel those moments of weightlessness. However, achieving this effect in a portable and practical way implies a more modern technology.
No, those were not the first, but beyond any joke... surely someone tried ;-)
To be precise and not to get lost among a multitude of inventions to jump, we can limit it to the geometry we know of the current jumpers; That shape that has been proven to be the best system for rebound exercise in a simple, stable and safe way. I refer to the spring system consisting of two arches joined at their ends with one or more elatic bands between them.
With these characteristics, we can already assume that it is not necessary to go back many centuries. But if man was able to create the Antiticera artifact 22 centuries ago, who says there haven't been several inventors of jumpers we don't know? The activity of jumping is too much fun not to have tried on many occasions with better or worse results.
So what were the first ones with this form?
Inspired by the desire to know the history of this product and, seeing the amount of falsehoods that the propaganda of some companies have extended, makes me embark on the task of finding out everything I can about who was really the first to devise the first modern jumpers.
I have to admit that, before investigating the topic, I also participated in the diffusion of that generalized hoax that Kangoo Jumps invented this product. Now I wish I could atone for my sin with this post.
In my personal deal of many years with Denis Naville, founder of Kangoo Jumps and my partner in the company,(5) I realized quite soon that, really, he was not an engineer or a complete inventor, although he contributed some ideas. Denis was an economist and entrepreneur who knew how to take advantage of some opportunities and coincidences of life to achieve the first commercial success of a brand of jumpers.
Bearing in mind that all the technical and creative development, since I started working in the company, was carried out in Spain by me and that the KJs are manufactured in Taiwan, it cannot be said that the "Swiss engineering" slogan we presumed and KJ continues doing it now..
But the jumpers existed before. In my first approach to the history of the jumpers, I hoped to grant the title of inventor of the jumpers to Gregory Lekhtman, a Canadian of Russian origin and creator of the Exerlopers brand .
And I have been very tempted to do so because it appears in public documents of KJ and patent records indicate that he applied for the patent for this bounce system in 1990. He has invented and patented numerous products related to medicine and fitness(6). Although he was not really the first to patent a system like the one at hand, he was the first to market the jumpers,(7) in any case we have to recognize his merit.
Shortly before G. Lekhtman, there is quite a lot of documentation on the internet that grants the authority in the invention of this product to a more prolific Japanese inventor, Yoshiro Nakamatsu better known in his country by Dr. NakaMats.(8)
Yoshiro boasts of having more than 3,500 patents and being the world's greatest inventor.(9) % uFEFF The truth is that it has a 1989 patent(10) that they are clearly jumpers and that he named them PyonPyon.
Patent War
G. Lekhtman applied for a patent in 1985(11) of a rebound system in which he uses metals and a tension adjustment system for different weights and another in 1990(12) which is the one that is implemented in the Exerlopers.
D. Naville already met the product and signed a distribution agreement for Europe in 1993. However, the chance made him meet the Taiwanese manufacturers of the Exerlopers and the PyongPyong at a fair in Munich, Germany_. The succession of exact events is not very clear since there are ethical issues in between,(13) but what is clear is that Denis began marketing a Kangoo Jumps model, the KJ-1, exactly the same as the Exerlopers and both They are exactly the same as the PyonPyon:_
Denis saw that if he wanted to legally market the product he had to make some changes and that led him to ask for help from a French industrial design studio that used to work for the Salomon brand. He also developed his own patent in 1994 which was granted in 1996(14) and whose only innovation was the incorporation of some anti-collapse rubbers that he named as "Turbos" % uFEFF (15) % uFEFF
Gregory and Denis had a conflict for infringing, the latter, Gregory's previous patent but the innovation of the turbos was enough for the authorities to decide that he could keep it. Really what Kangoo Jumps patented were the turbos, not the jumpers. However, this mechanism was introduced before, in the Gregory patent of 1985, only what its anti-collapse function did not claim but was only as a structural piece.
I remember that I once asked Denis about Y. Nakamatsu's and he told me that he was an opportunist who patents the objects he has seen and believes interesting, in this case being an Exerlopers. The truth is that, observing their patents, they do not usually go into many details and less in ornamental aspects, but in this patent, their drawings coincide with the shape of the soles of their PyongPyong, the Exerlopers and the KJ1:
That is obviously not a coincidence, nor is it a coincidence that the factory that produces the three brands (and other own brands) is the same Taiwanese factory.
Personally, I think that Y. Nakamatsu has a bit of "patent troll"(16) but is not as aggressive as others (if he has not prosecuted Exerlopers and KJ) because his patents do not usually solve the most basic aspects and they are not usually technically and commercially viable if you don't add a lot of development. However he has others, as in this case, which is quite complete. So I am going to grant Y. Nakamatsu the merit of being the inventor of modern jumpers, who use synthetic polymers instead of metals, because the invention totally fits their profile, both in personality and in studies and trajectory, ah!, and his patent was earlier_. I do not think that hundreds of magazine articles, internet and a movie(17) are wrong._
Currently Aerower is the only one of the aforementioned brands that has a jumpers patent in force due to the innovations it has developed. Aerower also has registered the designs of its main components(18) :
The era of shoes with springs
Before these dates we did not find anything remarkable in decades within the specifications that I have commented above, but I would like to fill that gap with the first commercial products of a shoe that is used to jump and that were sold as toys in the decades of the forty and, above all, in the fifties. I must say that due to their poor lateral stability (the springs tend to bend before compressing) and their ridiculous support, they deserve the nickname that some gave them: the "ankle-breakers".(19)
Now, THE ORIGINAL!
Investigating the patents I have been able to find the oldest reference of what we can consider jumpers according to the specifications that I mentioned above and dates from 1914 in France, It is described as a "sport or acrobatics device that adapts to a shoe and that it serves to increase the speed of the race or the amplitude of the jumps ". The patent is quite broad and includes alternative forms and mechanisms(20) .
Its author was a Parisian playwright whom we can already consider as "inventor of the jumpers". Gaston Devore (1859-1949) was very active in the Paris performing arts of the first half of the 20th century. He is the author of several plays, Collaborator and founder of specialized magazines (21) I'm going to assume that he probably patented it for use on stage in some comedy; or it occurred to him when he saw the circus shows of that time or some colleague. What I have clear is that he was a visionary and should have detected a business opportunity to spend the money on a patent, the only one that registered. Perhaps, the First World War that began that year, somehow prevented him from starting any company related to that product.
I want to pay tribute to his memory with the very limited edition that Aerower has produced with the Jumper1 Devore model, a modest contribution to the culture of this sport discipline:
Thank you that any contribution you want to add or correct the history that I mentioned here, send it to me through the channels that Aerower has on the contact page (https://aerower.com/contact) and know that I am avai lab le for dialogue.
