Description

Hand-operated planer

current technology

The invention relates to a hand planer according to the preamble of claim 1 .

Various hand-held power tools are known in which a tool can be stored in a housing or in a handle. For example, hand-operated jigsaws are known with longitudinally elongated recesses in the housing which can be closed by a cover and which serve as storage places for saw blades. But the taking out of these saw blades is cumbersome, wherein there is a big danger of hurting people because of some sharp saw teeth.

Advantages of the invention

The invention comprising the features of claim 1 has the advantage that the planer container with the spare planer can be located quickly, by means of which the spare planer can be easily and safely inserted manually onto the planer shaft. In this case, the planer, which is as sharp as a shaving knife, does not come into direct hand contact when changing, but one end can be located in the planer container and the other end can be pushed onto the planer shaft.

A part of the planer container that is used as a handle can be hooked under with a finger on the hand-operated planer, especially at the hand digging pit, so that the planer container can be easily removed from the hand-operated planer.

In the closed state, a part of the planer container that serves as a handle engages outwards—essentially flush—into the housing contour of the hand planer, and in particular protrudes only slightly to prevent the hand planer from being During operation, the planer container opens undesirably, for example by impacting the workpiece.

The handle of the planer container has a flat front wall, from which a U-shaped profile which is open at the rear extends vertically and longitudinally, so that the planer container can be constructed both lightly and stably.

The planer container is made of plastic and can be manufactured economically and easily.

The planer container can be secured against loss by means of an offside clip (berrastmittel) arranged in the housing.

The planer container has a compression spring, which preloads the planer located therein so that the planer can be fixed in a secure and vibration-proof manner.

Several stops are provided in the housing, wedged against the planer container in the form of bevels, so that the planer container can be placed in the hand-operated planer in a vibration-proof manner.

The compression spring and the overside snap spring of the planer container are designed in the form of leaf springs, which can be produced easily.

The planer container is provided with a color that contrasts with the color of the housing, in particular a signal color, so that it can be found easily or the risk of its loss can be reduced.

The planer container receives the stored planer blade upwardly (hochkant), so that the blade of the planer rests on the side wall and a part of the planer freely protrudes backwards, the planer container forms a storage space for the planer when changing the planer. Insert the handle on the planer shaft of a hand-operated planer. This prevents direct hand contact with the planer and reduces the risk of injury to the operator.

The planer container can also receive a plug-in wrench in a loss-proof manner, in particular a multi-sided plug-in wrench, which can be easily stored and removed and is readily available for changing the planer.

The front wall of the planer container is provided with a stepped edge profile which seals the planer container and closes it against the ingress of shavings.

The side walls of the planer container are each provided in a drawer-like manner with a guide groove which engages on guide ribs of the housing, and the planer container can be reliably guided longitudinally and locked in a vibration-proof manner.

The retaining spring for securing the planer container in the housing is integrally formed with the grip recess, in particular integrally integrated in the side shell parts of the housing, allowing economical receiving of the planer container.

The planer container is provided with a sliding key displaceable in the longitudinal direction, which acts on the end of the planer placed on the inside. As a result, the planing knife can be moved out of the planing tool container and positioned on the planing shaft particularly safely and without direct contact with the operator's hands after the free end has been introduced into the planing shaft.

Example

The hand-operated planer 10 shown in FIG. 1 comprises a housing 12 with an upwardly protruding main handle 14 with a switch button 16 on its underside.

The housing 12 is composed of several shell parts, of which the right shell part 18 and the left side with cover 20 can be seen. The housing 12 has a longitudinal axis 22 , with respect to which a shavings ejector 24 is arranged horizontally at right angles. The shavings ejector has two side outlets 26 , 28 which can be selectively controlled via a rocker 30 for rotating a shavings ejection ring 32 . The shavings can thus be ejected laterally to the left or to the right as an option. The housing 12 has an additional handle 34 at the front, by means of which the planing depth of the hand-operated planer 10 can be adjusted simultaneously by turning it about its vertical axis. A cable 36 protrudes rearwardly from the region of the main handle 14 , by means of which an electric motor (not shown) inside the housing 12 can be operated.

An axis 38 of a shaving tool container 40 extends parallel and spaced below with respect to the axis of the shaving ejector 24 . The planer container can be pushed into the interior of the housing 12 in a drawer-like manner through the lateral opening 42 of the side shell part 18 . The planing knife container 40 has a front wall 44 which covers the opening 42 when the knife container 40 is pushed in. Extending at right angles from the front wall 44 is a U-shaped profile region with two side walls 46 , 48 . These side walls are connected to one another at the bottom by a bottom wall 50 ( FIGS. 7 , 8 , 9 , 11 , 12 ).

A longitudinally insertable planer 54 can be seen in the planer container 40 , which is loaded and secured by a pretensioned leaf spring-like compression spring 56 . A hexagonal wrench 58 is fixedly held in the planer container 40 parallel to the planer 54 by a spring in the locking tongue 60 to prevent loss and vibration.

The front wall 44 of the planer container 40 can be hooked on the underside by the fingers of the operator's hand, wherein the fingers can reach under the front wall 44 into a hand picking recess 52 on the side housing part 18 .

Fig. 2 shows the above-mentioned detailed parts in the form of an exploded view, wherein besides the above-mentioned parts, the hand-cut hole 52 can be clearly seen and the rest of the detailed parts consistent with Fig. 1 will not be repeated.

In addition, a contact bevel 64 can be seen on one of the housings 12 , on which the end of the planer container 40 is to rest supportively and thus prevent vibrations.

FIG. 5 shows a spatial cross-section through the housing 12 along the planer container 40 vertically, in which the right side wall 48 of the planer container with a guide groove 66 can be seen in addition to the part shown in the previous figure. The guide groove 66 is formed by two spaced-apart parallel longitudinal ribs 68 , 69 which widen upwards or downwards in a V-shape towards the open end 51 of the planer container 40 . The planer container 40 can thus be conveniently guided conically into the housing 12 on guide strips 70 on both sides of the drawer opening. A planer 54 protrudes from an open end 51 at the rear of the planer receptacle 40 . The protruding free part of the planer can be moved together with the planer container 40 as a handle towards the planer shaft and inserted into the corresponding receiving opening, without the operator's hand having to come into direct contact with the planer for this purpose.

An angled end of a hexagonal wrench 58 protrudes from the upper side of the side wall 48 . As a result, the hexagonal wrench 58 can be easily withdrawn in the longitudinal direction under the locking tongue 60 and be used for quickly removing or clamping the planer holder on the planer shaft. For this purpose, a clamping device can be removed on the planer shaft via bolts/nails, which can be turned by means of a hexagonal wrench 58, whereby the planer to be replaced can be removed from the planer shaft and a new planer can be fitted.

In addition, the position of the planer 54 and the arrangement of the hexagonal wrench 58 spaced parallel to it can be seen, as well as the front wall 44 , which bears sealingly against the upper end of the Z-shaped profile of its upper side, not shown in detail. On the right side shell part 18 .

FIG. 7 shows a top view of the planer container 40, in which, in addition to the above-mentioned details, the locking tongue 60 in its relative position to the hexagonal wrench 58 and the pressing force in its pressed position against the planer 54 can be seen. Tighten the spring 56. Also visible is an integral holding projection (Haltelappen) 72, which is part of the planer container 40 and is pressed out of its bottom and pre-clamps the hexagonal key 58 to prevent it from being lost. Near the front wall, a second retaining protrusion 74 is assigned to the end of the hex key 58 .

FIG. 8 shows a bottom view of the planer container 40 , in which integrally extruded spring elements 56 , 60 , 72 , 74 are clearly visible as part bent out of the bottom wall 50 . The remaining details having the same reference numerals that have been explained in the above figures will not be repeated here.

FIG. 9 shows a detailed top view of the planer container 40 . Reference is made to FIG. 7 for those reference numerals given therein which have been explained in the above figures. The associated cross-section A-A according to FIG. 10 shows the opening 42 of the housing 12 with guide strips 70 on the housing 12 which engage in a guiding manner in the side walls 46 , 48 of the planer container 40 .

11 shows the arrangement of the compression spring 56 opposite the planer 54 and the arrangement of the hexagonal wrench 58 fixed by the holding projection 74 with its upwardly protruding elbow portion with a cross section B-B according to FIG. 9 .

In a non-illustrated embodiment of the invention, the planer container is provided with a sliding key displaceable in the longitudinal direction, which acts on the end of the planer placed on the inside. As a result, the planer—especially after its free end has been inserted into the planer shaft—can be moved out of the planer container and positioned on the planer shaft in a particularly safe manner and without direct contact with the operator's hand by the key relative to the planer container. This increases operator comfort and safety when changing planers.
