Description

The present invention relates to a tape dispenser of the type used to apply a strip of coating components to a predetermined surface such as paper. The present invention relates to a so-called correction tape dispenser used to apply a thin material on the surface of paper to cover writing or typing errors and to facilitate correction of the errors. However, the tape dispenser shown here can also be used to apply other coating layers to a given surface. The tape dispenser has an applicator tip that defines a rounded edge through which the tape passes and presses the tape against the surface of the paper. This tape consists of a backing ribbon made of paper or plastic with a continuous layer of coating components on one side. When the tape is pushed against the paper surface by the applicator edge and the edge moves over the paper surface, a new tape is drawn from the tape supply housed inside the dispenser body and the tape is wrapped around the edge. The used ribbon with the coating component transferred from the backing ribbon to the paper surface, a continuous strip of coating component deposited on the paper surface, and the coating component removed is the The entire dispenser is discarded when it is pulled back to the dispenser body for storage until consumed and the ribbon is used. The body of the dispenser forms a handle that the user grips with his hand.
Many conventional correction tape dispensers are difficult to hold in use due to their overall shape and configuration. In previous British patent application 2275042, the dispenser handle is oriented in a predetermined orientation relative to the applicator edge and, in use, a tape that can be held in the same way as a normal writing instrument. A tape dispenser with a guiding arrangement is shown. Thus, in use, the tape dispenser handle can extend upward away from the paper in a direction that generally tilts toward the user. This configuration makes the dispenser convenient and easy to use, but it means using the dispenser in the right hand and it is not easy to use if it is in the left hand. Had.
The present invention solves this problem, and as a solution, a handle is provided, a means for storing a tape supply source comprising a backing ribbon for supporting the coating component in the handle, and a backing ribbon from which the coating component is removed. And an applicator with an edge through which the tape passes, the edge pushing the tape to the surface and transferring a coating component from the backing ribbon to the surface, the handle comprising the edge A tape dispenser coupled to the applicator to allow selective adjustment of the handle relative to the applicator edge between positions inclined in opposite directions with respect to a plane perpendicular to.
Most advantageously, the handle is rotatable and adjustable with respect to the applicator between the most suitable positions for left and right hand use. A detent mechanism is provided to hold the handle in a selected adjustment position so that during normal use, the user does not have to handle the part and take special care to secure the handle.
In the presently preferred embodiment, the detent mechanism is in the form of a ratchet that allows the handle to be adjusted to several positions. In addition to allowing the dispenser to be easily used with the left or right hand, this has the advantage that the user can select a predetermined handle tilt according to personal preference in an advantageous and comfortable manner during use. .
Since the handle is adjustable, the area where the tape is fed from the applicator and the area where the consumed backing tape is pulled out of the applicator is not predetermined. Accordingly, the tape guide means is preferably arranged to guide the tape through a position substantially coincident with the adjustable axis of the handle relative to the applicator. In this way, the tape can be guided between the applicator edge and the position at which the handle is fixed independently of the adjustable position.
Advantageously, the tape guiding means comprises a pair of cylindrical rolls with a rotation axis parallel to the rotation axis and a sufficiently spaced surface so that the tape can run freely between them.
A full understanding of the invention can be obtained from the detailed description of the accompanying drawings, and reference should be made to the accompanying drawings in which: FIG.
FIG. 1 is an exploded perspective view of a correction tape dispenser according to the present invention.
FIG. 2 is a side view with the handle casing cover removed.
FIG. 3 is a perspective view showing the dispenser adjusted when using the right hand.
FIG. 4 is a view showing a dispenser adjusted when using the left hand.
The illustrated tape dispenser has a body or handle 1 having a casing assembled from a base portion 2 and a cover 3 secured together by fasteners and welding or other advantageous means. A pair of transverse spindles 4 and 5 are mounted in the casing and supported between the base and the cover and supporting the feed spool 6 and the take-up spool 7. The spool has an integral pulley, around which a continuous drive belt 8 is arranged, and when the correction tape is pulled from the supply spool 6, the take-up spool 7 is used to wind up the used backing ribbon. Rotate. Between the two spools, a part of the tape is guided out of the casing and around the working edge 10 of the applicator 12 protruding from the casing and back to the casing. The applicator has an arm 13 that supports a tip 11 that defines an edge 10, which facilitates the application of the corrective component to a surface, for example as shown in patent application PCT / US94 / 06585. It is either fixed to the arm or movably attached to it. The inner end of the arm supports a partial cylindrical shell bearing element 14 which is provided on the inner surface of the casing base and cover so that the applicator and handle are relatively rotatable. It arrange | positions so that it may rotate within the circular groove | channel 15. FIG. The opposing surfaces of the bearing element 14 and the casing journal groove have complementary detents such as a series of pips around one side and a series of indents around the other, forming a ratchet device The ratchet device can then be adjusted to take one of several positions between the two maximum rotational positions defined by the edge of the casing opening from which the applicator arm 13 projects. .
As best seen in FIG. 2, the handle can be adjusted to tilt and extend in the opposite direction with respect to a plane P perpendicular to the edge 10.
On each side of the applicator arm within the bearing element, a pair of rotatable guide rollers 16, 17 are supported, which are opposite to each other with respect to the pivot axis of the casing and the applicator 12. Arranged in the direction. The roller surfaces are separated by a small distance so that the tape can travel freely between them. Thus, the backing ribbon and the tape of corrective component, from the feed spool, coincide with the axis of rotation and pass through a position defined by the pair of guide rollers 16, 17 on one side of the applicator arm, and the applicator tip 11 passes around the edge 10 and coincides with the axis of rotation, passes the position defined by the pair of guide rollers 16, 17 on the other side of the applicator arm and then passes to the take-up spool 7. To do. In use, the dispenser is held by a casing or handle, and the edge 10 of the applicator tip is used to push the tape 18 against the paper surface. The edge is moved relative to a given surface in a direction perpendicular to the edge. The correction component moves from the backing ribbon to the paper surface. This is because the leading edge pulls a new tape from the feed spool 6 and passes around the leading edge from the backing ribbon 18 ′, so that the correction component is removed therefrom and taken up on the take-up spool 7. This is because the correction component is applied to the surface of the paper as a continuous strip 19 (see FIGS. 3 and 4).
The rotational movement possible between the applicator 12 and the handle 1 is a position that facilitates use by a left-handed user as shown in FIG. 4 from a position used by a right-handed user as shown in FIG. So that the handle can be adjusted easily. Furthermore, the ratchet device allows the angle at which the handle needs to be held against the paper to be adjusted for maximum comfort by left and right handed people.
It will be appreciated that variations of the tape dispenser described above are possible without departing from the inventive concept. For example, it has been mentioned that bottom friction guide pins can be used at predetermined positions on the guide rollers 16,17. In addition, the rotation adjustment between the handle and the applicator makes it possible to select several position adjustments, and the tip 11 can be moved to a ready position where fine adjustment of the position of the handle can be performed during use. It is.
