Abstract:
A connecting structure of a manual tool and its handle comprises a manual tool (1), a handle (4) and a handle connection trouser. The connection trouser is made up of a connection section (2) and a handle fixed section (3). Said fixed section forms an axial hatch vertical cylinder shape so that the handle could be inserted into it. The handle and the handle fixed section are fixedly connected through a connecting bolt (5). The connection structure in the invention has a simple structure and is convenient and safe to connect, assemble, adjust and change the manual tool. It is realized the standardization connection of the handle and the manual tool when using.
Abstract:
A vehicle window glass holder (10) is disclosed, which is capable of easily fixing a window glass only by rotating a shaft (40), and easily extracting the shaft by reversely rotating the shaft to allow reuse. The holder (10) comprises a holding member (30) and a shaft (40). The shaft includes projecting pieces (74) provided on its tip, a support portion (72) for supporting the projecting pieces, and a main body (80) connected to the support portion. The holding member includes a pair of opposing pieces (52, 53), and each of the opposing pieces has a shaft inserting hole (54, 56). The shaft is inserted into the holes of the holding member. By rotating the shaft, the shaft is engaged with the holding member, and thus the shaft is prevented from being extracted from the holding member.
Abstract:
A method and an attachment clamp for attaching a seat belt to a seat frame of a bus seat are provided. The attachment clamp includes at least one upper arm having at least one slot disposed through the at least one upper arm. The attachment clamp includes at least one lower arm that is received within the at least one slot of the at least one upper arm. A receiving channel is defined by the at least one upper arm and the at least one lower arm. The receiving channel is configured to receive the seat frame. The upper arm and the lower arm are pivotable with respect to each other and are fastenable to each other.
Abstract:
A distortion-free weldless method of joining tubular elements (11, 12) provides for connecting a first tubular element (11) to a second tubular element (12). An assembly includes an insert (13) with screw threads (13a) and the inserted is located inside the first tubular element (11). A connector fitting (14) is mounted to the insert (13) with a screw (15). The second tubular element (12) is secured to the connector fitting (14) with a fastener (16) through transverse holes (12a, 14e) through both the second tubular element (12) and the connector fitting (14). A second tubular section (14e) is positioned over a stepped outside diameter (14d) of the connector fitting (14) and the transverse holes (12a, 14e) are aligned. The fastener (16) is installed through the transverse holes (12a). The fastener (16) secures the connector fitting (14) to the second tubular section (14e) and doesn't allow the screw (15) to disengage or loosen. A resulting joint is structurally rigid in all planes without a visible fastener on the first tubular section (14c).
Abstract:
A one-piece, unitary clamp (1) for a longitudinally extending structural member (T, T2, 73, 75), such as a tube, is provided which can be mounted to a mounting surface (3) such that the structural member received in the clamp is either parallel to or perpendicular to the mounting surface. Additionally, two clamps can be fastened together to form a cross-over clamp, a T-clamp, or another compound clamp which will hold two structural members together in a desired relationship. The clamping arms (15) of the clamp have an elastic hinge (31) which allows an upper portion of the clamping arm to move relative to a lower portion of the clamping arm when the clamp is tightened. Additionally, when the clamp is loosened, the elastic hinge of the clamping arms cause the clamping arms to pull away from the structural member received in the clamp to fully release the grip of the clamp on the structural member.
Abstract:
A supporting tube for a tubular structure, in particular a vertical post for a railing, a ladder step, or equivalent, having at least at one end a curved receptacle space where a crossing tube is connectable. On the curved margin of the curved space, the wall of the supporting tube has been bent to form a projecting supporting widening (2). The supporting widening has been made in that prior to cutting the supporting tube to desired length there has been drilled a hole at its cut-off point, the margins of which hole have been drawn out to form a collar projecting from the supporting tube, whereupon the supporting tube has been cut off so as to divide the collar into supporting widening arcs remaining on the ends of different supporting tubes.
Abstract:
In a structural supporting frame the problem of compact storage and shipping and easy assembly and disassembly is solved by providing a frame structure and method of making including a pair of similarly constructed end supports (22) arranged to define an inverted U-shaped member, each having a specified notch configuration formed at the comer portions of the respective U-shaped members for receiving and securing the end portions of opposed side rails (23) for maintaining the end supports in a stable predetermined spaced relationship, and optional cross rails (24) detachably interconnected between the opposed leg portions (30) of the respective end supports. The method of forming such frame structure includes the steps of forming a notch (26) at spaced intervals along a readily bendable length of a stock material (30) whereby the length of stock material can be readily bent into an inverted U-shaped end support (27) in a manner whereby a side rail (23) is gripped and secured at the bent comers of the end supports, and securing a cross rail (24) between the opposed leg portions of the bent supports.
