A quick connecting device and a shower room assembly are disclosed. The quick connecting device comprises an inserting member, a receiving member and a locking key. The shower room assembly comprises a track connected at a corner uses the above quick connecting device.

A connection device for mobile frame structures includes a bracket on a surface having a cam shaft and a cam lock has a spiral axial slot having a locking groove and a central cam groove. A cam follower, a spring and a force stop are positioned in the central cam groove. A retention device holds the components in the cam groove. A structural support is engaged to the cam lock. An intersection between the spiral axial slot and the central cam groove has one or more detents which engage the cam follower prior to engagement of the cam lock to the bracket. The cam shaft is positioned in the spiral axial slot and the cam lock is rotated moving the cam shaft into the locking groove and depressing the cam follower relative to the spring to lock the cam shaft into the locking groove.

A wall anchor (1), having an anchor plate (2) with a front face (3) and a rear face (4), a fixing portion (5) which protrudes from the front face (4) of the anchor plate (2), which extends along a centre axis (M) and has a threaded structure (6) for receiving an anchor bolt (7), and two hooks (8, 9) which protrude from the rear face (4) of the anchor plate (2). The hooks (8, 9) are configured such that the wall anchor (1) can be fixedly connected to a profile rail (18) by protrusions (21) of a profile rail (18), with respect to forces acting in the direction of the centre axis (M).

A slotted-type rigid coupling is manufactured so that the internal-diameter dimension of a first shaft hole of a circumferentially divided shaft-fastening part is the same as that of a shaft. The first shaft hole is widened by widening force from a pressing mechanism provided with a fastening bolt, and the shaft is inserted through the first shaft hole up to a shaft insertion hole. The widening force is ceased, the first shaft hole is narrowed by fastening force from the pressing mechanism, and the shaft is securely fastened. When the shaft is securely fastened to the shaft-fastening part by the fastening bolt, eccentricity in the shaft is prevented or minimized.

The angle connector (100) has two free ends (110, 120) aligned perpendicular to each other, for the purpose of being inserted into an associated cavity of a supporting profile (10, 20), such that at every free end (110, 120) of the angle connector, a passive means of fixation (131, 132, 133) is provided, via which from one outer side of the supporting profile (10, 20), the respective end of the angle connector can he detachably connected to the associated supporting profile by way of a complementary active fixation element (40, 44). Between the free ends that are aligned perpendicular to each other, a corner element is provided, with profile elements (111, 112) compatible with the supporting profiles provided on its two outer sides that are positioned perpendicular to each other, respectively reaching until the height of the associated surface (55) of the corner element (110).

A wall anchor (1), having an anchor plate (2) with a front face (3) and a rear face (4), a fixing portion (5) which protrudes from the front face (4) of the anchor plate (2), which extends along a centre axis (M) and has a threaded structure (6) for receiving an anchor bolt (7), and two hooks (8, 9) which protrude from the rear face (4) of the anchor plate (2). The hooks (8, 9) are configured such that the wall anchor (1) can be fixedly connected to a profile rail (18) by protrusions (21) of a profile rail (18), with respect to forces acting in the direction of the centre axis (M).
