A silicone paint brush artist's tool (20) includes a handle (22) and a novel painting tip (38). The painting tip (38) is made of a resilient silicone having a generally three-dimensional paint contacting working surface (41) that has a maximum cross-sectional diameter (42) no larger than a maximum cross-sectional diameter of the handle (22). The tip (38) is preferably attached to the handle (22) using a ferrule (28) and expansively locking the tip (38) into a cavity (34) of the ferrule (28) by insertion of an insert (44). The insert (44) may be a common screw or a barbed, fluted extension of the handle (22). The tips (38) may include an insert cavity (34) and have various shapes and hardnesses and may be optionally color coded. The ferrules (28) also may be reversibly attached to the handle (22), in which case a kit comprising multiple interchangeable painting tips (38) may be provided.

A clamp ring (500;1000) and process for manufacturing a clamp ring (500;1000) to effectively reduce, if not eliminate, waste scrap from the manufacturing process. The clamp ring (500;1000) and process for manufacturing the same, results in clamp ring (500;1000) having a seam (1100) formed by a metal joining technique such as welding, brazing, bolting, soldering, and clinching.

A joint structure (10) and a joining method include a joint component (11) formed of synthetic resin having a fusible shaft (11c), and a joining component (12) having an insertion hole (12c) that is inserted with the fusible shaft. The joint component (11) and the joining component (12) are joined by applying ultrasonic vibrations to fuse the fusible shaft, which is inserted in the insertion hole. The joint component (11) and the joining component (12) each include positioning members, at least in two places, which position the joint component and the joining component when engaged with each other. The joining method includes a step of determining position of the joint component and the joining component through positioning members, while the fusible shaft is inserted in the insertion hole of the joint component and a step of positioning the joint component at a predetermined position through the positioning members. While positioning the joint component and the joining component, the joint component and the joining component are joined in such a manner that a gap is formed between the insertion hole and the fusible shaft so as to interrupt contact between the insertion hole and the fusible shaft.

Die vorliegende Erfindung betrifft unter anderem ein Einstanzelement mit einem hohlen Kopfteil größerer Querabmessung, mit einem hohlen Schaftteil kleinerer Querabmessung, der von einer Seite des Kopfteils weg ragt, wobei eine ringförmige Blechanlagefläche auf der genannten Seite des Kopfteils ausgebildet ist und den Schaftteil umgibt, mit mehreren Rippen am Außenumfang des Schaftteils, die sich in axialer Richtung entlang des Schaftteils von der Blechanlagefläche bis nahe an das freie Ende des Schaftteils erstrecken. Es werden auch ein Vormontagebauteil, ein Zusammenbauteil und ein Verfahren beansprucht.
摘要:
The invention relates to a bolt element (10) comprising a shaft part (12), whose first end (14) is designed to be riveted (16) with a plate element (18), in particular with a sheet steel part. Said bolt element is characterised in that the other end (20) of the shaft part (12) has a spherical configuration (22), whose diameter (D) is greater than that of the shaft part (12). This allows a bolt element comprising a spherical head to be produced in an extremely cost-effective manner and guarantees that the spherical head has no burr, which leads to the abrasion of the socket that glides on the spherical head during operation.

This invention provides a fixing method for fixing a member to be fixed (5,6) that is placed on a shaft member (1), the fixing method comprising the steps of: forming an annular groove (3) in an outer circumference of the shaft member (1); placing the member to be fixed onto the shaft member (1) until the member to be fixed (5,6) contacts a step portion (2) provided in the shaft member (1); placing a locking member (10) onto the shaft member (1) until the locking member (10) contacts the member to be fixed (5); and caulking the locking member (10) to the shaft member (1) such that one end of the locking member (10) is brought into press contact with the member to be fixed (5) and an inner circumference portion of the other end of the locking member (10) comes into contact with the annular groove (3).

摘要:
The invention relates to a device (1) for linking a number of components, especially for linking the housing parts (3, 4) of circuit breakers. The inventive device comprises a link element (2) that is provided with a shaft (2) which comprises an insertion end (2c) and an opposite holding end (2b). Said shaft extends through through openings (7, 8) that are in alignment with one another in the zone where the components (3, 4) are linked. The aim of the invention is to make sure that the link element (2) is centered when it is twisted to brace said components (3, 4) and at the same time to minimize the extent of contortion or twist necessary to lock the components. To this end, a first assembly recess (10) is configured as a centering cone (11). Said assembly recess accommodates the holding end (2b) and is aligned with the through openings (7, 8). The holding end (2b) has a conical shape and defines a clamping surface (5) that corresponds to the centering cone (11).
