Abstract

Apparatus and method based on the concept of a split ring (604) having a plurality of internal angles (624a, 624b) that engage a shank or post (600) having an annular ring with an angle complementary to the angle of the split ring. The present disclosure provides for a wide range of insertion and withdrawal forces between the latch engagement lever and the latch engagement body. Changes in the insertion contact angle and contact area on the engagement stem and corresponding changes in the insertion contact angle and engagement area on the engagement body can significantly change the insertion force required to engage various devices. Likewise, changes in the degree of angle between the angle of departure and the area of contact on the engagement rod and corresponding changes in the angle of departure and area of contact on the engagement body can significantly change the total departure force required to disengage the various devices. Thus, the instant latching mechanism provides insertion and withdrawal forces that can be controlled independently of each other.

Embodiment

Each mode of execution disclosed herein relates to fixation method and device, utilizes coupling mechanism force that one is installed reliable but is convenient to and is fixed on the object with dismantling.Fixation method disclosed herein and device are applicable to various objects and device.As described below, fixation method disclosed herein and device can be advantageously used in device and object are combined, and wherein this device and on being fixed to this object the time, suffers lateral impact forces probably from this object vertical extent fixedly the time.For example, fixed mechanism disclosed herein can be used for empennage is fixed on surfboard or other ships, (cleat) is fixed on the shoes with non-skid nail, (wheel truck) is fixed on double skidding shoes, inline skate or the slide plate with roller, skates are fixed on the roller skate, furniture parts or other various paired device/objects are fixed together.

As described below, some mode of execution disclosed herein relates to fixing device and the method for utilizing spring locking device (for example tilting coil spring, cantilever spring, opening cup spring, opening dog chart, or the like).

Before describing the present invention in detail, it is favourable describing embodiment's environment that the present invention can implement.Such example is a surfboard.Surfboard is a kind of general long ship of comparing with width.Surfboard may stand in top buoyancy deck when generally forming surfer's surfing.But it must be understood that surfboard also can be used for paddling, for example sit, crouch, or the like the time.In addition, other propulsion methods of sail and so on also can be fixed on the surfboard, for example are used for board sailing.The surfboard in many modern times can be made with polystyrene or polyurethane foam.Surfboard can cover with the resin of one or more layers glass fiber cloth and polyester or epoxy resin and so on.

Another environment that the present invention can implement is the non-skid nail design of shoes.The like that is arranged in metal threaded parts on the conventional non-skid nail and sole can increase the weight of shoes greatly.Shoes weight is whole relevant with sports achievement; Shoes are light more, and power is more little, so the move energy that needs of contestant competitor player is more little.The shoes that weight is lighter help the contestant competitor player that pin and leg are moved to another position quickly from a position.As the key of achievement, shoes weight is the character that the contestant competitor player generally acknowledges, footwear manufacturers is also so thought.Footwear manufacturers when describing and advertise, can be with shoes weight alleviate when selling shoes and Competitor's comparison point.

Metal non-skid nail and the metal threaded insert (threaded inserts) corresponding with them may allow the people who wears footwear feel under the weather, and particularly dress for a long time is because be used to make the effect that the polymer of sole begins to be subjected to the power of metallic stud.Metal parts can become the pressure point that more protrudes between the anti-skidding column (threaded cleat stud) of sole and screw thread installation sooner or later.This is just not uncomfortable, but may become the root of harmful foot.

Screw thread non-skid nail with metal or plastics manufacturing can also greatly limit the potential geometry design of non-skid nail.Because " penetrating " needs of screw, current non-skid nail design limitation is in conical geometrical shape.Non-skid nail alternative geometries in shape is unpractical.Attempting repeatedly to aim at non-skid nail after non-skid nail is screwed into sole does not accomplish.
