Description

Treadmill cushion device

Technical field

The present invention relates to a kind of treadmill cushion device, refer to a kind of buffer unit of tool damping effect especially.

Background technology

When general treadmill is run for avoiding the user, because of pin is trampled in the excessive and injured situation generation of the moment reaction force that runs plate, therefore, be equipped with buffer unit 6, as shown in Figure 8, because this buffer unit 6 is salty with rubber system, and user's body weight is all inequality, required cushion effect is also inequality, and therefore, this buffer unit 6 also can't effectively solve the injured problem of user.

And another kind of buffer unit 7, as shown in Figure 9, it is a material of utilizing different densities, provide the user purpose of different cushion effects to reach, but must try out respectively after the unlike material when using, could select the material that is applicable to user's body weight, so, allow the user feel quite inconvenient.

So, come across the buffer unit 8 that inside is full of liquid on the market, as shown in figure 10, though this buffer unit 8 has preferable cushion effect, after being full of liquid and can't cooperate the user of different weight and adjust the buffer capacity of buffer unit 8.

Therefore, all above-mentioned

buffer units

6,7,8 all have improved necessity in addition.

Summary of the invention

Main purpose of the present invention; be to solve the above problems and a kind of buffer unit of treadmill is provided; it is to utilize a device of trampling that is available for users to run thereon to be connected with a buffer unit; make in the running user who tramples different weight on the device; can be by the adjustment of buffer unit; all can provide preferable cushion effect with runner to different weight, so have the protection user avoid injured function.

For reaching aforementioned purpose, the present invention is applied to treadmill, and it comprises: one is positioned over ground pedestal, tramples a device and a buffer unit.Wherein, this pedestal has the handrail that extends upward and be available for users to help and and is connected in the framework of this pedestal with an end.Trample device and then have a race plate of being supported by framework, this runs on plate doubling-up around the flexible race band of a rotation capable of circulation.And this is trampled device and more is connected the active force that is born when running with suitable minimizing user with the buffer unit that can adjust buffer capacity.

The specific embodiment

See also Fig. 1 to Fig. 7, be the selected example structure of the present invention shown in the figure, this only for the usefulness of explanation, is not subjected to the restriction of this kind structure in patent application.

When the present invention was applied to treadmill, as shown in Figure 1, it comprised: one is positioned over ground pedestal 1, tramples a device 2 and a buffer unit 3.Wherein, this pedestal 1 has the handrail 11 that extends upward and be available for users to help and and is connected in the framework 12 of this pedestal 1 with an end.Trample 2 in device and have a race plate 21 of being supported by framework 12, doubling-up is with 211 around the flexible race of a rotation capable of circulation on this race plate 21.The position that forms stressed maximum on this races plate 21 downwards because the runner when running, tramples usually is near the position of section therein, and therefore, present embodiment is to establish a buffer unit 3 respectively in these both sides, bottom surface, position, as Fig. 2 and shown in Figure 3.

In present embodiment, but this buffer unit 3 comprises the hollow body 31 and a compress cell 32 of a blanketing gas.This body 3 is salty with the material system of deflection and hard a piece of wood serving as a brake to halt a carriage, for example rubber.This compress cell 32 is the inside of being located at body 31 in present embodiment, in order to do to body 31 inner inflatable.

This body 31 has a buffer part 311 and a fixed part 312, this fixed part 312 is fixed in the both sides that these race plate 21 bottom surfaces are close to the middle section by retaining element 313 (for example screw) with body 31, and this buffer part 311 then is positioned at the outside of fixed part 312 in present embodiment.This buffer part 311 has big inner space, and behind the filled gas, its bottom still is lower than the bottom of fixed part 312, and keeps supporting urgent framework 12.This body 31 has an air inlet 314 and an exhaust outlet 315 again, and after compress cell 32 starts, entering and discharging of gas with adjusting body 31 internal gas pressures, and then provides the user suitable cushion effect.

This compress cell 32, as shown in Figure 4, it comprises one and is fixed in motors 321, in the body 31 and also is fixed in pressurized cylinder 322 in the body 31, and one to be located at body 31 outside and be communicated with body 31 exhaust outlets 315 and have the air pressure sensing element 323 of detecting and degassing function concurrently.

Wherein, this motor 321 links a bent axle 325, but move back and forth to drive a piston 326 that is positioned at pressurized cylinder 322 one-way check gas flow, this pressurized cylinder 322 also has one and is communicated with body 31 air inlets 314 and is positioned at first conduit 327 of piston 326 1 sides, and one be positioned at piston 326 opposite sides and be communicated with second conduit 328 of body 31 inner spaces, makes gas be inhaled into pressurized cylinder 322 through pistons 326 and be squeezed into body 31 inner spaces by air inlet 314.Certainly, this first conduit 327 and second conduit 328 are respectively equipped with a non-return valve 329, to prevent gas backstreaming.

During use, starter 321, motor 321 can drive bent axle 325 and then piston 326 is moved back and forth, when piston 326 is pushed to second conduit, 328 1 sides, gas will be inhaled in the pressurized cylinder 322 by air inlet 314, then piston 326 oppositely moves, and then gas can pass through piston 326, is entered body 31 inner spaces by piston 326 crowded pushing away then.So go round and begin again, can constantly fill gas in body 31, and can be by air pressure sensing element 323 to predict body 31 gas inside pressure.

When the user is trampling when running on the device 2, comfort level when the user can comply with body weight own and running is adjusted the gas pressure in this body 31, so, the user whenever tramples a step forward and can be cushioned device 3 to the active force of trampling device 2 and forming and absorb when make running, allow the user when running, heel, ankle and knee joint can bear less reaction force.By this, make the present invention reach suitable damping and protection user and avoid injured function.

Further, the present invention also can select the mode of automatic sensing for use, sees also Fig. 5, and it is the action flow chart of automatic sensing.When user's body weight not simultaneously, the air pressure sensing element 323 in this compress cell 32 can record body 31 internal pressures, when pressure is too big, this air pressure sensing element 323 can be suitable partly gas discharge; During insufficient pressure, 323 of this air pressure sensing elements can see through and electrically connect and starter 321 makes gas enter body 31 inside, and reach required gas pressure.

Moreover because this body 31 is to be located to run bottom surface, plate 21 both sides, therefore, 3 of this buffer units are subjected to longitudinal pressure and do not bear side-friction, and can be arranged long service life.

Certainly, still there are many examples in the present invention, therebetween the only variation on the details.See also Fig. 6, it is the second embodiment of the present invention, what they were different with previous embodiment is, trample device 2A except that running plate 21A, comprise that more one supports the framework 12A of this race plate 21A, this buffer unit 3A is installed in leading portion place, this framework 12A bottom surface, and buffer unit 3A is positioned between this framework 12A and pedestal 1A.

See also Fig. 7; it is the third embodiment of the present invention; in present embodiment; trample device 2B except that running plate 21B; comprise that more one supports the framework 12B of this race plate 21B, this buffer unit 3B is installed in this to trample stage casing, device 2B bottom surface and back segment place, and buffer unit 3B is trampled between device 2B and the ground at this; so, also can reach the protection user and avoid injured function.
