Description

Tool for Installing a Mounting Sleeve The invention relates to a tool for installing a mounting sleeve for an audio head unit of vehicle.
Generally such a mounting sleeve -which is also called a radio sleeve -is installed into a recess in an instrument panel of the vehicle. Usually such a mounting sleeve has several tabs in the walls of the sleeve which need to be bended outwards in order to lock the mounting sleeve within the recess of the instrument panel or dashboard of the vehicle. Existing tools which are designed to bend several tabs outwards at one time suffer from a lack in durability and repeat-use to extend these tabs within the mounting sleeve or radio sleeve in order to secure it into its instrument panel opening.
It is therefore an object of the present invention to provide a tool of the initially mentioned kind which allows for an easy and efficient installation of the mounting sleeve.
This object is solved by a tool having the features of claim 1. Advantageous configurations with convenient further developments of the invention are specified in the dependent claims.
The tool according to the invention is designed for installing a mounting sleeve for an audio head unit of a vehicle into a recess in an instrument panel of the vehicle. For example a mounting sleeve for a radio can be installed utilizing the tool. A head unit typically gives a user control over the vehicle's entertainment media such as AM/FM radio, satellite radio, CDs, cassette tapes, MP3, GPS navigation, Bluetooth and the like.
An audio head unit often enables control over audio functions such as volume, band, frequency, speaker balance, speaker fade, bass, treble and the like.
The tool according to the invention comprises a first frame member fixed to a first arm of a pair of pliers and a second frame member fixed to a second arm of the pair of pliers. At least one of the frame members comprises at least one protrusion configured to bend a tab of mounting sleeve outwards by moving the pair of pliers in an open position.
Therefore, by expanding the pliers the mounting sleeve tabs can be expanded or bent outwards in order to secure the mounting sleeve in the recess provided in the instrument panel or dashboard of the vehicle.
By moving first end sections of the arms of the pair of pliers away from each other, second end sections with the frame members are also moved away from each other.
This expanding movement of the pair of pliers leads to a corresponding movement of the at least one protrusion. The movement of the at least one protrusion in turn bends the at least one tab of the mounting sleeve outwards. This results in a quick and reliable fixation of the mounting sleeve within the recess.
Such a tool therefore provides for a particularly easy and efficient installation of the mounting sleeve. In consequence, in an assembly line setting the overall assembly time and assembler effort can be decreased.
In an advantageous embodiment the tool comprises a spring element for moving the pair of pliers in the open position. Then a force only needs to be applied by a worker handling the tool to press the end sections of the arms of the pair of pliers towards each other when introducing the frame members into the mounting sleeve. However, the movement of the pail of pliers in the open position, in which the at least one tab of the mounting sleeve is pushed outwards and into the dashboard material or into a recess within the dashboard material, is effected by the spring element. This makes the handling of the tool particularly easy. Further, the force which is needed for bending the tabs outwards can be well-defined by the spring element.
At least one of the frame members can comprise a spacer for limiting a movement of the pair of pliers in a closing position in which the frame members can be introduced into the mounting sleeve. Such a spacer therefore acts like a stop to pre-set the tool to a proper width before bending the tabs. This contributes to an ease of handling of the tool and to a high precision when utilizing the tool.
Further advantageously the first frame member and second frame member each comprise two protrusions, wherein each protrusion is configured to bend two tabs of the mounting sleeve outwards. With such a configuration of the tool a total of eight tabs in opposing walls of the mounting sleeve can be bent outwards simultaneously. This allows for a particularly quick and efficient installation of the mounting sleeve, in particular radio sleeve.
It has further proven advantageous, if a protruding length of the at least one protrusion or of at least one of the protrusions can be varied. Such a configuration allows to set a degree of bending of the locking tabs. Different designs of the tabs of the mounting sleeve as well as different designs of the recess provided in the instrument panel of the vehicle can be particularly well taken into account by adjusting the protrusions which can in particular be formed as pins.
Preferably a locking element, which can in particular be configured as a screw, can be provided for fixing the at least one protrusion or at least one of the protrusions in a position relative to the frame member, in which the protrusion has the desired protruding length. Such locking elements, in particular screws, provide a good flexibility in adjusting the protruding length of the protrusions and therefore of the degree of bending of the tabs of the mounting sleeve.
The at least one protrusion or at least one of the protrusions can have a tapered end section configured to contact the tab of the mounting sleeve. With such tapered protrusions the instrument panel material or dashboard framework can be cleared. This allows to anchor the tabs in a particular reliable manner within the recess in the instrument panel or dashboard.
It has further proven advantageous if at least one of the frame members has a stop configured to abut against an edge of the mounting sleeve, when the frame members are introduced into the mounting sleeve. Such stops make it particularly easy to place the protrusions or bending pins exactly at the desired position, at which they will bend the tabs upon the opening of the pair of pliers.
The frame members can in particular be formed as parallel bars. Preferably one of the frame members has two flanges extending perpendicular to the bar. With such a configuration it can particularly easily be achieved that the frame members and the flanges abut against interior sides of the mounting sleeve when the pair of pliers is brought in the open position.
Preferably a length of one of the bars substantially corresponds to a distance between the flanges of the other bar. Then the bar without the flanges can move freely and easily between the flanges as the pair of pliers is brought into the open position and into the closing position, respectively.
The features and feature combinations mentioned above in the description as well as the features and feature combinations mentioned below in the description of figures and/or shown in the figures alone are usable not only in the respectively specified combination, but also in other combinations or alone, without departing from the scope of the invention. Thus, implementations are also to be considered as encompassed and disclosed by the invention, which are not explicitly shown in the figures or explained, but arise from and can be generated by separated feature combinations from the explained implementations.
Further advantages, features and details of the invention are apparent from the claims, the following description of preferred embodiments as well as based on the drawings.
Therein show: Fig. 1 a tool which can be utilized to install a mounting sleeve in a recess in an instrument panel of a vehicle, wherein protrusions in the form of pins simultaneously bend tabs outwards which are provided in opposing walls of the mounting sleeve; Fig. 2 mounting sleeve of Fig. 1 in a perspective view, wherein the mounting sleeve has eight tabs which have been bent outwards; Fig. 3 a perspective view of the tool according to Fig. 1 but without the mounting sleeve; Fig. 4 another perspective view of a part of the mounting tool shown in Fig. 1; and Fig. 5 a further perspective view of the mounting tool shown in Fig. 1.
A tool 10 shown in Fig. 1 is designed to install a mounting sleeve 12, in particular a radio sleeve, into a recess in an instrument panel or dashboard of a vehicle such as a car or a truck.
Fig. 2 shows the mounting sleeve 12 in a perspective view. The mounting sleeve 12 has an upper wall 14 and a bottom wall 16. Together with side walls 18, the upper wall 14 and the bottom wall 16 define a rectangular space in which an audio head unit such as a radio for the vehicle can be installed. However, to securely fix the radio within the recess in the instrument panel accommodating the mounting sleeve 12, the radio sleeve or mounting sleeve 12 itself needs to be secured within the recess. To achieve this, tabs 20 which are provided in the upper wall 14 and in the bottom wall 16 of the mounting sleeve 12, respectively are bent outwards by means of tool 10. In the example shown in the figures the mounting sleeve 12 has eight such tabs 20 which can be bent outwards simultaneously by the tool 10.
As can be well seen from Fig. 1, the tool 10 comprises a first arm 22 of a pair of pliers and a second arm 24 of the pair of pliers fixed to each other in a movable manner at an axis of rotation 26 which can for example be provided by a rivet. An end section of the first arm 22 is fixed to a first frame member 28 of the tool 10. In a like manner an end section of the second arm 24 is fixed to a second frame member 30 of the tool 10. These frame members 28, 30 are formed as parallel bars.
As can for example be seen from Fig. 3 the second frame member 30 has two protrusions in form of two pins 32. These two pins 32 are configured to bend outwards the four tabs 20 provided in the bottom wall 16 of the mounting sleeve 12 when the frame members 28, 30 are introduced into the mounting sleeve 12 and the pair of pliers is moved in an open position shown in Fig. 1. To achieve this movement a spring 34 is provided between the arms 22, 24 of the pair of pliers. The pliers are therefore designed as expanding pliers.
As can be particularly well seen from Fig. 5, the first frame member 28 also has two protrusions in the form of pins 36. These protrusions or pins 36 bend outwards the tabs provided in the upper wall 14 of mounting sleeve 12, when the pair of pliers is in the open position shown in Fig. 1. When the frame members 28, 30 are introduced into the mounting sleeve 12 and the pair of pliers is moved in the open position by the spring 34 all the tabs 20 of the mounting sleeve 12 are therefore bent outwards simultaneously.
In particular from Fig. 3 it can further be seen that the second frame member 30 has a spacer 38 which is configured as a stop. This spacer 38 in form of a rod fixed to the second frame member 30 limits the movement of the frame members 28, 30 towards each other when the arms 22, 24 are compressed against the force of the spring 34. By providing this spacer 38 or stop the tool 10 can be pre-set to a proper width before the bending of the tabs 20 of the mounting sleeve 12.
The pins 32, 36 can be adjusted. In other words, a length of the pins 32, 36 by which they protrude from a surface of the frame members 28, 30 can be varied. This surface of the frame members 28, 30 is in contact with the upper wall 14 and the bottom wall 16 of the mounting sleeve 12, respectively, when the pair of pliers is in the open position (see Fig. 1). In order to fix the protruding length of the pins 32, 36 locking elements in the form of screws 40 are introduced into respective screw holes 42 provided in the frame members 28, 30 (see Fig. 3 and Fig. 5). These set screws 40 therefore allow an adjustment of the bending pins 32, 36.
As can be well seen from Fig. 4, the pins 32 arranged at the second frame member 30 have a tapered end section 44. This allows the pins 32 particularly well to clear the material of the dashboard at the locations where these pins 32 push the tabs 20 of the bottom wall 16 into the material of the dashboard or instrument panel.
As can be further seen from Fig. 4 for example, at least one of the frame members 28, preferably has a stop 46 which helps to locate the tool 10 with respect to an edge 48 of the mounting sleeve 12 (see Fig. 1 and Fig. 2). As the frame members 28, 30 are introduced into the mounting sleeve 12 these stops 46 abut against the edge 48 and thus limit the introduction of the frame members 28, 30 into the mounting sleeve 12.
These stops 46 also assure that the pins 32, 36 are exactly located in abutment with the tabs 20 before the tabs 20 are bent outwards by the force of the spring 34 which pushes the end sections of the arms 22, 24 away from each other.
It can further be seen from Fig. 5 that the frame members 28, 30 are formed as parallel bars. In the embodiment shown the first frame member 28 has two flanges 50 which extend perpendicular to the bar. This provides a good rigidity to a structure comprising the bar and flanges 50. Also, these flanges 50 can have the at least one stop 46 which limits the introduction of the frame members 28, 30 into the mounting sleeve 12 (see Fig. 3 and Fig. 4). In a corner region where the flanges 50 are in contact with the bar or frame member 28 a reinforcement plate 52 can be provided to increase the stability of the structure.
It can further be well seen from Fig. 5 that a length of the second frame member 30 corresponds to a distance between the inner sides of the flanges 50.
With the radio installation tool 10 shown in the figures it is possible to simultaneously set all the locking tabs 20 in the radio sleeve or mounting sleeve 12. To achieve this the adjustable pins 32, 36 bend the respective tabs 20 outwards as the spring 34 expands the pair of pliers and thus moves the pair of pliers in the open position shown in Fig. 1.
This tool 10 makes the radio sleeve installation very quick and efficient and decreases the overall assembly time and assembly effort during manufacture of the vehicle.
