1. Field of the Invention
The present invention relates to a size-adjustable telescopic tool support comprising a seat and a top cover, in which the top cover is moveable with respect to the seat to adjust the accommodation space of the telescopic tool support, so as to carry tools of various sizes.
2. Description of the Prior Art
A tool support known in the art conventionally comprises a box provided with a fastener disposed on the outer surface of its top cover to fix hand tools of a specific size to the fastener and align them with each other, such that it is convenient to display, take out and carry the hand tools. However, the size of the conventional tool support cannot be adjusted, such that it can only be used for storing hand tools of specific sizes. Hand tools that do not match the size of the tool support cannot be properly stored/supported.
Under the circumstances, if the user only has a tool support of a fixed size that can accommodate specific combinations of tools and he/she wish to store/carry tools of other sizes for the hand tool with a length smaller than that of the tool support, the accommodation space of the tool support may be too large compared with the size of the hand tool, thus causing a waste of space; and for the hand tool with a length greater that of the tool support, the accommodation space of the tool support may be too small compared with the size of the hand tool, and thus cannot carry the hand tool properly. If the user wishes to carry a combination of various hand tools, it is needed to prepare several tool supports of various sizes so that hand tools can be stored/supported in appropriate tool supports.
In view of the above, various sizes of tool supports should be manufactured to accommodate different packages of hand tool sets, and this inevitably results in the addition in manufacturing processes and costs.
In this regard, carrying hand tools of various sizes by using a single tool support is an important task to be achieved by the present invention.
SUMMARY OF THE INVENTIONThe present invention discloses a tool support comprising a seat and a top cover, in which the top cover at least partially encloses the seat, and can be moveably adjusted with respect to the seat to extend or retract the entire accommodation size of the tool support so as to accommodate various sizes of hand tools.
A telescopic tool support according to the present invention comprises a seat, a top cover partially enclosing the seat and being slidable therewith, and an adjustable, telescopic locking device adaptable for not only engaging the seat and the top cover but also locking the engagement at a desired coupling location.
According to a preferred embodiment of the present invention, the adjustable, telescopic locking device has at least one locking tab and at least one engagement-actuating device. The at least one locking tab is disposed on the seat, and separated from the top cover. The engagement-actuating device is disposed on the inner side of the at least one locking tab. A coupling device is provided between the at least one locking tab and the top cover, and particularly, the coupling device is in the form of a toothed structure consisting of at least one tooth on said at least one locking tab and a corresponding rack on the top cover. The at least one tooth and the corresponding rack can be engaged with each other. With the engagement-actuating device, the at least one tooth on the at least one locking tab can be pushed to engage with the rack of the top cover to avoid the top cover to slide with respect to the seat. When the tool support is to be extended or retracted back, the engagement-actuating device should be unlocked first so as to allow the top cover to be adjusted to the required position; and when the engagement-actuating device is locked, the top cover and the seat are fixed together.
The above engagement-actuating device can be in the form of a latching device, an eccentric engagement-actuating member, a supporting rod, an elastic engagement-actuating ring, or the like, which enables the coupling device between the seat and the top cover.
In a further embodiment of the present invention, the telescopic locking device has at least one locking tab which is disposed on the seat and engaged with said top cover. A coupling device is provided between said at least one locking tab and the top cover, and particularly, the coupling device is in the form of at least one tooth on said at least one locking tab and a rack of the top cover at the corresponding position of the at least one locking tab. The at least one tooth and the rack can be engaged with each other, such that the top cover is fixed to the seat and will not slide relatively. When the tool support is to be telescoped, an external force is applied to the at least one locking tab to bend the same inward, such that it is separated with the top cover, and at this time the top cover can be adjusted to a desired position. After the external force is removed, the at least one locking tab can be returned to the engaged state, such that the top cover and the seat are fixed with each other and will not slide with respect to each other.
In order to avoid the locking tab to be fatigue or broken due to the over bending, a stopper is disposed on the inner side of the locking tab to prevent the locking tab from being overbent. It can be appreciated that those skilled in the art may think of some other alternatives to prevent the locking tab from being overbent without using the stopper.
In the above two embodiments, the coupling device can be disposed on the side surface or top surface of the top cover and the seat, and the coupling device is not limited to the combination of tooth and rack. Those skilled in the art can appreciate that the coupling device is used for engaging purposes and can be easily modified to accomplish the purposes of the present invention.
With the present, multi-section adjustment of a tool support can be achieved to meet the accommodation requirement of hand tools of various sizes. The accommodation size of the tool support can therefore be reduced to facilitate carrying. The telescopic tool support of the present invention can also be arranged with other tool sets to form a new tool kit, or be placed in a bigger tool set.
The features of the present invention can be better understood by referring to the accompanying drawings and the following detailed description of the preferred embodiments.
BRIEF DESCRIPTION OF THE DRAWINGS
As shown in
The locking tabs 13 are separated from the second top wall 21 when they are not actuated by the engagement-actuating devices. A toothed structure 14, preferably in the form of at least one tooth 14, is disposed on each of the locking tabs 13 (
Accordingly, when the locking tab 13 is in an engaging position, the toothed structure 14 is engaged with the rack 23, such that the top cover 20 cannot slide with respect to the seat 10. In other words, the coupling device constituted by the toothed structure 14 and rack 23 enables the coupling between the seat 10 and the top cover 20 under the aid of the engagement-actuating device. When the locking tab 13 is in an disengaging position, the toothed structure 14 is disengaged with the rack 23, such that the top cover 20 can slide with respect to the seat 10 and the accommodation size of the telescopic tool support can be adjusted. In other words, the coupling device constituted by the toothed structure 14 and rack 23 enables the decoupling between the seat 10 and the top cover 20 by releasing the engagement-actuating device. It is known to those skilled in the art that the engagement between the locking tab 13 and second top wall 21 is not limited to the combination of tooth and rack, and can be achieved by other coupling devices, such as a combination of interfered tooth and rack, a combination of a protrudent round ball and a corresponding circular hole, and a combination of a catch protrusion and a corresponding catch hole. The examples of the engagement-actuating device would be given in detail below.
Preferably, to ensure that the locking tab 13 and the second top wall 21 are in an engaged state such that the toothed structure 14 and the rack 23 are engaged with each other to couple the top cover 20 to the seat 10, an engagement-actuating device is disposed on the inner side of the locking tab 13 to fix the locking tab 13 in an engaged state, and to prevent the locking tab 13 from being separated from the second top wall 21. Referring to
According to a further modified embodiment of the present invention, the engagement-actuating device can be in the form of one or preferably two eccentric engagement-actuating members 40, as shown in
