Description

CONNECTION ADAPTER

DESCRIPTION

Field of the Invention

The present invention relates to a connection adapter that enables to connect two parts, which are desired to be mounted, to each other such that no gap will be formed on the positive connection surface. Background of the Invention

Bolts are used as connecting members in assembly of machines, steel constructions and many other similar structures. The bolts are used as connecting members in different forms such as nut bolts, bolts without nuts, or studs. One portion of the studs is directly screwed to one of the parts to be connected. Studs are used in systems which need to be frequently disassembled. Connection and dismounting of the bolts are performed by kits called wrench or screwdriver.

Bolts are used very frequently because they are easy to fasten, can be prepared in standardized manner, are produced easily and can easily adapt to different types for different applications. The nut is a connecting member that is used together with the bolt. It is one of the fasteners, which is useful for connecting parts to each other by the influence of the friction power between the threads of the two connecting members and due to the pressure occurring between the two parts upon slight elongation of the bolt, and which is tapped and hollow inside. Both of the parts that will be connected in the procedure of connection with bolt and nut are drilled at a diameter large enough to allow unrestrained passage of the bolt. The bolt is passed through both of the parts having a hole thereon. The connection is tightened by using a nut and thus the two parts are connected. If the work environment is shaky, in such cases, the connection is made secure by using either a spring lock washer or a second nut, or by using the method of securing the other nuts.

When the two parts are preferred to be connected by positive connection (bolt and nut, etc.), the surfaces of the two parts, which will be connected, should contact each other. If a gap is formed between the two parts on the positive connection surface, a connection surface, which will allow the two parts to contact each other when connecting thereof, cannot be enabled. In case the contact surface cannot be formed, it is not possible to connect the two parts to each other via positive connection. Even if the two parts preferred to be connected to each other are connected, the gap formed between the two parts affects robustness and reliability of the connection. Due to the gap that is formed, the connection is deformed after a while and connection of the two parts should be repeated. Repeating the connection both increases labor and total mounting time, and causes loos of time.

There is no connection adapter in the state of the art, which fills in the gap between the two parts to be mounted, and enables to obtain a sturdy positive connection. Objectives of the Invention

The objective of the present invention is to provide a connection adapter that enables to connect two parts, which are desired to be connected, by covering the gap in the case that a gap is formed on the positive connection surface. Another objective of the present invention is to provide a connection adapter which closes the gap between two parts, in between which a gap is formed, thereby enabling the surfaces of the parts to contact each other. A further objective of the present invention is to provide a connection adapter which provides a more sturdy connection by filling the gap between the two parts.

Summary of the Invention A connection adapter; which is developed to fulfill the objective of the present invention, and which is defined in the first claim and the claims dependent thereon; is designed to close the gap when a gap is formed on the positive connection surface between two parts. The connection adapter enables the connection surfaces to contact each other when performing a positive connection of two parts. The connection adapter comprises a clamping member, a bushing and a movable shaft placed into the bushing, a resilient member, a ring and a cover that covers the rear end of the bushing. The clamping member passes through the hole provided on the first part and fits into the movable shaft located in the bushing. The two parts that will be connected are moved towards each other by tightening the clamping member, and the contact surface of the movable shaft fills in the gap formed between the two parts.

The clamping member (2) is the positive connection member, which passes through the hole on the first part (A) and fits into the movable shaft (3), and which, by clamping the first part (A) and the second part (B), carries out mounting of the two parts to each other. Diameter of the clamping member (2) is smaller than the diameter of the hole on the first part (A). The clamping member (2), which passes through the hole on the first part (A), fits into the movable shaft (3). A movable shaft (3) is provided in one embodiment of the invention. The movable shaft (3) is the member which fills in the gap formed between the first part (A) and the second part (B) and which enables connection of the two parts. The movable shaft (3) has a cylindrical geometry. The movable shaft (3) is hollow inside and its inner diameter is larger than the outer diameter of the clamping member (2) so as to allow the clamping member (2) to fit therein. There is a contact surface (31) on one end of the movable shaft (3). The contact surface (31) may have a preferred geometry. In the preferred embodiment of the invention, the contact surface (31) is circular. Diameter of the circular contact surface (31) is smaller than the diameter of the hole provided on the second part (B). This way, the contact surface (31) can pass through the hole provided on the second part (B). After the first part (A) and the second part (B) that are intended to be mounted are connected to each other, the contact surface (31) provides contact between the two parts thereby filling in the connection gap. There is a flat surface (32) provided on the upper portion of the movable shaft (3). The flat surface (32) is obtained by flattening the circular section of the movable shaft (3). The flat surface (32) enables the movable shaft (3) to follow a linear path when moving. There is a slot (33) on the end of the movable shaft (3) that is not facing the second part (B). The slot (6) is a groove into which the ring (6) provided in the bushing (4) fits. A bushing (4) is provided in one embodiment of the invention. The bushing (4) is the member in which the connecting members are placed and into which the clamping member (2) fits. The bushing (4) may have a preferred geometry. In the preferred embodiment of the invention, the bushing (4) is produced in a cylindrical form. There is a plate (41) on the end of the bushing (4) that contacts the second part (B). The plate (41) may have a preferred geometry. In the preferred embodiment of the invention, the plate (41) has a quadrangular form having a circular hole in the center thereof. Diameter of the circular hole in the center of the plate (41) is smaller than the diameter of the hole provided on the second part (B). The plate (41) contacts the second part (B). The plate (41), upon contacting the second part (B), applies a force on the second part (B). The plate (41) supports the contact of the first part (A) and the second part (B) with each other. In order to enable sectional compliance with the movable shaft (3), practically the same form with the flat surface (32) of the movable shaft (3) is given to the inner geometry of the bushing (4). Inner diameter of the bushing (4) is smaller than the outer diameter of the movable shaft (3) so that the movable shaft (3) can fit therein. The end of the bushing (4) that does not contact the second part (B) is exposed.
