[composition member of the present invention]

Fig. 2, Fig. 3 represent combination, the exploded perspective view of adjusting gear K respectively, and Fig. 4 A represents the cut-open view that cut for adjusting gear K according to the line segment A-A among Fig. 2.

As shown in Figure 3, adjusting gear K comprises a body 1, a sliding members 2, a footing element 3, a flexible member 4, a stop element 5, a lid 6.

Body 1 is a hollow circuit cylinder member.Have a path 10, two first guidance parts 11, a guide hole 12 (shown in Fig. 4 A) and a threaded portion 120 in the inside of body 1.Path 10 is a depression that forms on the 100f1 of end, and two first guidance parts 11 are two protuberances on the interior sidewall surface that is formed at path 10, and guide hole 12 is the perforation that is formed at the other end 100f2 and is connected in path 10.Threaded portion 120 is the outside surfaces that form body 1 in the mode that approaches end 100f1.

Sliding members 2 is cylindrical member just like.Sliding members 2 comprises two second guidance parts 21, a location division 22, two guide holes 23.Two second guidance parts 21 are periphery 200f0 that is formed at and two depressions that are connected in upper and lower surperficial 200f1,200f2, and this two second guidance part 21 is two first guidance parts 11 that slidably are matched with body 1.Location division 22 is a through hole that is formed at sliding members 2 middle positions and is connected in upper and lower surperficial 200f1,200f2, and is formed with one first joint portion 220 on the internal face of location division 22.In the present embodiment, first joint portion 220 is the threaded portion.Two guide holes 23 are for being adjacent to location division 22 and being connected in two perforation of upper and lower surperficial 200f1,200f2, and this two guide hole 23 is in order to as pore (air vent).

Though first guidance part 11 in the present embodiment, the number of second guidance part 21 are 2, but also can only adopt single first guidance part and single second guidance part (but all not shown) in other preferred embodiment, be equally can be so that sliding members 2 is arranged in removable mode quite smoothly among the path 10 under the suitable design.In addition, in other preferred embodiment, the geometric configuration of first guidance part, second guidance part also can adopt the exchange mode to finish, that is first guidance part can be a depression, and second guidance part is a protuberance.

Footing element 3 is combined by a seat cushion 31 and a rod member 32.Seat cushion 31 is by the made conical member of rubber, is formed with a pilot hole 30 on a surperficial 300f1 of seat cushion 31, is a kind of design that is suitable for Different Plane.Rod member 32 comprises one second joint portion 320 and a head 321, this head 321 is to be embedded among the pilot hole 30, and because head 321 has a plurality of toothing 321t, so make and to combine closely between seat cushion 31 and the rod member 32, can not cause improperly to come off because of rotation.Be with move mode mutually and combine between second joint portion 320 and first joint portion 220.In the present embodiment, second joint portion 320 is the threaded portion.

Flexible member 4 is for having the telescopic member at both

ends

41,42, and stop element 5 is for having the disc element of pilot hole 50.In the present embodiment, flexible member 4 is a compression spring, and stop element 5 is a pad (washer).

Lid 6 is for having the member of U type section.Be formed with a threaded portion 620 (shown in Fig. 4 A) on the internal face of lid 6, this threaded portion 620 is the threaded portions 120 in order to be matched with body 1.

[installation of the present invention]

Please consult Fig. 3, Fig. 4 A simultaneously.

Be matched with two first guidance parts 11 of body 1 simultaneously when sliding members 2 utilizes its two second guidance part 21, sliding members 2 just can carry out slippage along two first guidance parts 11.Subsequently, footing element 3 is stretched to the guide hole 12 of body 1 via its rod member 32, and utilize second joint portion 320 of rod member 32 to screw in first joint portion 220 that is matched with sliding members 2.When sliding members 2 is adjusted to respect to both after the allocation of body 1, stop element 5 is convenient to be buckled on the terminal part of rod member 32 with its pilot hole 50.Subsequently, flexible member 4 is placed in the mode of rod member 32 among the path 10 of body 1 to be enclosed in the stop element that mutually combines 5, and then utilizes the threaded portion 620 of lid 6 to be matched with the threaded portion 120 of body 1 again.Thus, the flexible member 4 between body 1 and sliding members 2 is just oppressed and is presented confined state, that is the both ends the 41, the 42nd of compressed flexible member 4 contact at respectively on sliding members 2, the lid 6.

Through as shown in the above description, after the package program of finishing adjusting gear K, foot piece 3 is an adjustable element, that is foot piece 3 is to carry out between a primary importance (Fig. 4 A) and the second place (Fig. 4 B) or the switching between other position with respect to sliding part 2.

[operation of the present invention]

See also Fig. 5, when a load L acts on the adjusting gear K that is positioned over plane W, load L oppresses for flexible member 4 via lid 6, and the reacting force L ' that comes from plane W oppresses for flexible member 4 via sliding members 2 that mutually combines and foot piece 3 simultaneously.Under the effect that is subjected to load L, reacting force L ', sliding members 2 is with respect to the bottom surface 100b of the path 10 of body 1 and produced a displacement D (being compared to Fig. 4 B), that is flexible member 4 produces an amount of contraction under the clamping effect between sliding members 2, the lid 6.

It should be noted that, when sliding members 2 produces moment when moving in the path 10 of body 1, space between lid 6, sliding members 2 (that is, flexible member 4 spaces of living in) moment that just relatively produces volume changes (reduce or increase), the moment air-flow that is caused between lid 6, sliding members 2 is can be disposed to the external world via

guide hole

23,12 or suck between lid 6, sliding members 2 via

guide hole

12,23, so to reach the effect of damping (damping).The number of guide hole 23, position and size thereof can change according to demand.

Therefore, under the effect of the air damping power that bracing force that flexible member 4 of the present invention is provided and two guide holes 23 are produced, the vibrations, the energy that are produced during via weight or external force input all can be reduced or be eliminated effectively.

Though disclosed the present invention in conjunction with above preferred embodiment; yet it is not in order to restriction the present invention, anyly is familiar with this operator, without departing from the spirit and scope of the present invention; can do and change and retouching, so protection scope of the present invention should be with being as the criterion that claim was defined.
