, Description:FIELD
The present disclosure relates to the field of arresters for preventing dislocation of articles on trolleys.
BACKGROUND
The background information herein below relates to the present disclosure but is not necessarily prior art.
While conveying an article on a trolley, there are chances of the article getting dislocated from its original location on the trolley due to speed, momentum, or higher center of gravity (CG) of the article from the base of the trolley. For example, in an assembly or manufacturing facility of the automobile industry, engines may get dislocated and subsequently may fall down while being conveyed on the trolleys due to speed and momentum of the trolley or weight and higher CG of the engines from the trolley base. Placing the engine back on the trolley is a time consuming job, and may require sophisticated crane arrangements. Further, the engine may get damaged after falling from the trolley. There is also a probability of the engine falling on an operator or a person in the nearby vicinity, and causing a major injury to the operator or the person. Conventionally, mounting holes are provided on the engine to receive fasteners that fasten the engine to the trolley. In another approach, clamps are used to secure the engine to the trolley. However, in some cases, the use of fasteners, clamps, or any other conventional locks is not possible due to space constraint.
Therefore, there is felt a need of an arrester that arrests the movement of an article conveyed on a trolley, and alleviates the abovementioned drawbacks of conventional locking arrangements.
OBJECTS
Some of the objects of the present disclosure, which at least one embodiment herein satisfies, are as follows.
An object of the present disclosure is to provide an arrester that prevents dislocation of an article being conveyed on a trolley.
Another object of the present disclosure is to provide an arrester that is compact.
Yet another object of the present disclosure is to provide an arrester that is easy to operate.
Yet another object of the present disclosure is to provide an arrester that is durable.
Other objects and advantages of the present disclosure will be more apparent from the following description, which is not intended to limit the scope of the present disclosure.

The present disclosure envisages an arrester for preventing dislocation of an article conveyed on a trolley.
The arrester, of the present disclosure, is now described with reference to Figure 1 through Figure 11.
Referring to Figure 1 to Figure 5, an arrester 100, in accordance with an embodiment is shown.
The arrester 100 comprises a bracket 105, a stopper 125, and a locking pin 135. The bracket 105 is configured to be connected to a trolley 50. The bracket 105 (as shown in Figure 6) has a base 107 and a pair of bracket arms 109, 111. The base 107 is connected to the trolley 50. The pair of bracket arms 109, 111 extends from the base 107 such that the base 107 and the pair of bracket arms 109, 111 define a space.
In an embodiment, the bracket 105 is a ‘C’ – shaped bracket.
In an embodiment, the bracket 105 is fastened to the trolley 50 using fasteners. The base 107 of the bracket 105 has holes configured thereon to receive the fasteners.
In another embodiment, the bracket 105 is welded to the trolley 50.
The stopper 125 (as shown in Figure 8 and Figure 9) is pivotably connected to the bracket 105. Further, the stopper 125 is configured to abut an article being conveyed on the trolley 50 in a locking configuration of the stopper 125. More specifically, the stopper 125 is operated in two modes, viz., the locking configuration and an unlocking configuration. In the locking configuration, the stopper 125 abuts the article on the trolley 50 and prevents the displacement of the article on the trolley 50. In the unlocking configuration, the stopper 125 is away from the article and the article can be lifted or displaced from the trolley 50.
The shape and size of the stopper 125 are determined as per the application requirement, size and shape of the trolley 50, and distance between the bracket 105 and an article on the trolley 50. In an embodiment, the stopper 125 has a curvilinear shape. More specifically, the stopper 125 has shape of a human finger.
The stopper 125 is configured to be received in the space defined by the base 107 and the bracket arms 109, 111.
The arrester 100 further includes a stepped pin 120 (as shown in Figure 11) configured to pivotably connect the stopper 125 to the bracket 105 such that the stopper 125 is pivotable about a longitudinal axis of the stepped pin 120. Holes 108, 126 are configured on the stopper 125 and on the bracket arms 109, 111 to facilitate passing of the stepped pin 120 therethrough.
Further, the hole configured on a first bracket arm 109 of the pair of bracket arms is a stepped hole. The head of the stepped pin 120 rests on the stepped hole, whereas the shaft of the stepped pin 120 passes through the hole on the first arm and subsequently through the hole on a second bracket arm 111.
The locking pin 135 (as shown in Figure 10) is configured to be received in a slot 127 configured on the stopper 125 to prevent angular displacement of the stopper 125 about the bracket 105. This locks the stopper 125 and prevents displacement of the article on the trolley 50. The locking pin 135 is inserted in the slot 127 to define the locking configuration of the stopper 125. In this configuration, the stopper 125 is abutted against the article, and its angular movement about the bracket 105 or about the stepped pin 120 is prevented by inserting the locking pin 135 in the slot 127. Further, to unlock the stopper 125, the locking pin 135 is pulled out from the slot 127. This allows the stopper 125 to be angularly displaced about the stepped pin 120. This defines the unlocking configuration of the stopper 125.
The bracket 105 has a first through hole 113 configured on the first bracket arm 109 of the pair of bracket arms. The first through hole 113 is configured to facilitate passage to the locking pin 135. More specifically, the first through hole 113 and the slot 127 are aligned such that the locking pin 135 passes through the first through hole 113 and is received in the slot 127 on the stopper 125.
The slot 127 is configured in a way such that when the locking pin 135 is received in the slot 127, angular displacement of the stopper 125 in at least one direction is restricted. In an embodiment, the stopper 125 has a wall 128 that defines the slot 127. The wall 128 prevents the angular displacement of the stopper 125 in anticlockwise direction viewed from the first bracket arm 109 side when the locking pin 135 is received in the slot 127.
The arrester 100 further comprises a support 150 (as shown in Figure 7) connected to the first arm 109. In an embodiment, the support 150 is fastened to the first arm 109. Holes are provided on the support 150 and on the first arm 109 to receive fasteners. In another embodiment, the support 150 is screwed or welded to the first arm 109.
The support 150 is configured to support the locking pin 135. The support 150 comprises a second through hole 155 that provides a passage for the locking pin 135.
The support 150 can have any suitable shape. In an embodiment, the support 150 has a ‘Z’ – Shaped configuration.
Further, the first through hole 113 on the first arm 109 and the second though hole 155 on the support 150 register with each other. More specifically, the longitudinal axis of the first through hole 113 and the longitudinal axis of the second though hole 155 are aligned.
The locking pin 135 has a projection 140 configured circumferentially on a body of the locking pin 135, and is arranged on the body between the first through hole 113 and the second through hole 155 when locking pin 135 passes through the first through hole 113 and the second through hole 155. The projection 140 limits the movement of the locking pin 135 between the first through hole 113 and the second through hole 155.
The arrester 100 further comprises a biasing member 160. The biasing member 160 is mounted on the locking pin 135 between the first through hole 113 and the second through hole 155. In an embodiment, the biasing member 160 is mounted on the locking pin 135 between the projection 140 and the second through hole 155. In an embodiment, the biasing member 160 is a compression spring.
The biasing member 160 is compressed against the support 150 when the locking pin 135 is moved away from the stopper 125. When the locking pin 135 is released, the biasing member 160 allows the locking pin 135 to come to its initial position.
The arrester 100 further includes a knob 170 mounted on one end of the locking pin 135. The knob 170 facilitates holding of the pin 135 while pulling the pin 135 out of the slot 127. The end of the locking pin 135, on which the knob 170 is to be mounted, has external threads 142 to receive the knob 170. The knob 170 is provided with a central hole having internal threads complementary to the external threads 142 configured on the locking pin 135.
In an operative configuration, initially, the bracket 105 is mounted on a trolley. Further, the stopper 125 is pivotally mounted on the bracket 105 using the stepped pin 120. One end of the locking pin 135 is inserted through the first through hole 113 such that the locking pin 135 is received in the slot 127 on the stopper 125 in the locking configuration of the stopper 125. Further, the support 150 is connected to the first arm 109 of the bracket 105 such that the locking pin 135 passes through the second through hole 155, and the projection 140 and the biasing member 160 are between the first through hole 113 and the second through hole 155.
To operate the arrester 100, a user pulls the locking pin 135 away from the stopper 125. The stopper 125 is then abutted to an article whose displacement on the trolley is to be prevented. Further, the user releases the locking pin 135 to allow the locking pin 135 to be inserted in the slot 127 on the stopper 125. Once the locking pin 135 is inserted, the angular movement of the stopper 125 is restricted, and thereby the displacement of the article is prevented as the stopper 125 is strongly abutted against the article. To allow the displacement of the article on the trolley, the user pulls the locking pin 135 away from the stopper 125, and angularly displaces the stopper 125 away from the article.
The arrester, of the present disclosure, prevents dislocation of an article being conveyed on a trolley, is compact, and is easy to operate. The weight of the arrester 100 can be as low as 100 gms.
Further, the arrester has few numbers of parts which reduces the manufacturing and maintenance cost of the arrester.
