Abstract
Official abstract text for this publication.
A space-saving floating joint including a locking mechanism that locks a swing of a movable base with respect to a fixed base is provided. A floating joint includes: a fixed base; a movable base; a floating mechanism that floatingly supports the movable base swingably with respect to the fixed base; and a locking mechanism that fixes the movable base in a state of not being swingable with respect to the fixed base. The floating mechanism includes a spherical bearing having a spherical surface, and a spherical washer part that supports the spherical surface slidably. The locking mechanism is provided in an inner part of the spherical bearing.
First claim
Opening claim text (preview).
What is claimed is: 1 . A floating joint comprising: a fixed base; a movable base; a floating mechanism that floatingly supports the movable base swingably with respect to the fixed base; and a locking mechanism that fixes the movable base in a state of not being swingable with respect to the fixed base, wherein the floating mechanism includes a spherical bearing having a spherical surface, and a spherical washer part that supports the spherical surface slidably, and the locking mechanism is provided in an inner part of the spherical bearing. 2 . The floating joint according to claim 1 , wherein the locking mechanism includes an inner cylinder that is coupled and fixed to the movable base, an intermediate cylinder that covers an outer periphery of the inner cylinder, an outer cylinder that covers an outer periphery of the intermediate cylinder and that is coupled to the fixed base, and an elastic member that couples the intermediate cylinder and the movable base, the intermediate cylinder is provided in a manner of being relatively movable in an axial direction of the intermediate cylinder with respect to the inner cylinder and the outer cylinder, and an outer peripheral surface of the inner cylinder and an inner peripheral surface of the intermediate cylinder have step parts engaged with each other. 3 . The floating joint according to claim 2 , wherein at least one step part is provided in an axial direction of each of the inner cylinder and the intermediate cylinder in a positional relationship of a center of the spherical bearing being therebetween.
