摘要:
A one-piece attachment device for mounting an end of a fluid actuated member on a support component. The attachment device has a plurality of first flexible fingers which terminate at a tip provided with an outwardly extending shoulder and a tapered camming surface. The fingers are moved inwardly by engagement of the camming surfaces with the support component as the fingers pass through an aperture formed therein, and thereafter attempt to return toward their original position. The finger shoulders engage the support component to secure the attachment device to the support component. A second plurality of inwardly and upwardly extending flexible fingers are also provided on the attachment device and define an interior opening. A mounting stud of a fluid actuated member is inserted through the interior opening and the second fingers will move outwardly initially upon passage of the stud therethrough, afterwhich the finger attempt to return toward their original position securely gripping and retaining the stud therebetween to secure the fluid actuated member to the attachment device. In another embodiment the second fingers have inwardly extending tangs, the tips of which form the interior opening for securing and gripping the mounting stud therein.

A pneumatic spring for motor vehicles which includes a closed spring volume and two spring surfaces of different sizes adapted to be subjected to pressure acting in opposite directions. The two spring surfaces each have an effective spring surface which is variable in size as a function of travel of the pneumatic spring. A separate support arrangement is provided for each of the spring surfaces for supporting the spring surfaces so as to be coaxial with respect to one another. A linking construction is provided for elastically linking the two support arrangements with one another so as to enable an axial distance between the support arrangements to be variable within predetermined limits as a function of a pressure of the closed spring volume.

In the use of certain types of delicate measuring apparatus, and in the use of high power optical instruments, and various other situations, it is highly desirable to have a table top or other surface free of all vibration. This disclosure relates to improvements in vibration isolated tables which have heavy table tops of high inertia supported on air mounts that damp out the vibrations of the ground or floor from which the table is ultimately supported. Improved air mount envelope constructions provide effective damping and convenient adjustment of the weight that the air mounts can support, and effective variations in the air mounts own natural frequency when necessary. Safety features protect against human error of excessive and insufficient pressure in the air mounts.

A spring arrangement includes two coaxial spring components (4a, 4b) which are mounted so as to oppose each other. Each of the spring components includes a rolling-lobe flexible member (6a, 6b) and a roll-off piston (8a, 8b) corresponding thereto. The two rolling-lobe flexible members (6a, 6b) define a common double rolling-lobe flexible member (6) and the two spring components (4a, 4b) have a common outer jacket (10). A simple assembly and a reliable fixation of the double rolling-lobe flexible member (6) on the outer jacket (10) is provided. For this purpose, the double rolling-lobe flexible member (6) has a clamp ring (18 or 26) mounted internally. The outer jacket (10) includes two parts (10a and 10b) having respective ends. The double rolling-lobe flexible member (6) is clamped between these ends with the aid of the clamp ring (18 and 26). The air spring arrangement is especially applicable in the forward wheel fork (16) of a two-wheel vehicle.

A shock absorbing device includes a housing having a port formed in an end wall, one or more air envelopes disposed in the housing for cushioning purposes, a tube slidably received in the housing and a piston secured to the tube and slidably engaged in the housing and engageable with the envelope, and a valve engaged in the port of the housing for selectively blocking the port of the housing. A pumping device may be used for selectively pumping air into or out of the housing, such as for pumping air into the housing when either of the air envelopes is broken.
