Spikningsapparat med magnetisk liammare. Nailing device with magnetic liammare.

Tidigare aro k5.nda spikningsapparater, forsedda med magnetisk hammare. Dâ det emellertid vid deras anvandning varit nodvandigt att anvanda ena handen for att halla appa- ten och den andra handen for att pa.verka hammaren saint da apparaterna trots detta icke kunnat anvandas i alla onskade lagen, t. ex. vid spikning i tak, ha apparaterna lake underlattat arbetet i sadan grad, att de kommit till flagon mar utstraekt anvandning. Apparaten enligt foreliggande uppfinning, som ãr billig att framstalla och vari ingà ett ringa antal mycket oOmma saint tvangsmassigt arbetande delar, kan daremot hanteras med en hand och anvandas i alla tankbara lagen. Apparaten tarvar heller ingen starre kraft och kan riled ett enkelt handgrepp omstallas for spikning uti olika material. Formerly known as nailing machines, equipped with a magnetic hammer. However, when using them, it was necessary to use one hand to hold the appliance and the other hand to act on the hammer, since the appliances could nevertheless not be used in all the desired laws, e.g. when nailing to the ceiling, the lake appliances have facilitated the work to such an extent that they have come to flake mar extensive use. The apparatus according to the present invention, which is inexpensive to manufacture and which contains a small number of very oOmma saint compulsively working parts, can, on the other hand, be handled with one hand and used in all conceivable laws. The device also does not require any more rigid force and can be adjusted with a simple hand grip for nailing in different materials.

App araten en ligt uppfinningen kannetecknas i huvudsak darav, att hammaren är forskjutbar uti ea r6r, genom vars ena mynning en spik i taget Or anordnad att av hammaren indragas i for islagning lampligt lage, och att namnda "'or am' i sin tur forskjutbart uti en, en slagfjfider inneslutande cylinder eller dylikt, varvid slagfjadern Or anordnad att vid rorets intryckning spannas, for att, nar tillracklig spannkraft uppnatts, frigoras genom utlosning av en hammaren paverkande kolv, forsedd med en utlOsningsanordning, som vid riirets intryckning mot verkan av slagfjadern medbringar kolven. Genom att med ena handen fatta om cylindern samt en-hart genom att pressa in riiret uti cylindern astadkommes salunda, nar slagfjadern erhallit erforderlig spannkraft, en islagning av spiken astadkommande utlosning av hammaren. The apparatus according to the invention can be characterized mainly by the fact that the hammer is displaceable in a tube, through one of its mouths one nail at a time Or arranged to be retracted by the hammer in a position suitable for hammering, and that the said "or am" in turn displaceable in a cylinder enclosing a strut spring or the like, wherein the strut spring Or is arranged to be tensioned when the rudder is depressed, so that, when sufficient clamping force has been reached, it is released by releasing a hammer-actuating piston, provided with a release device which By grasping the cylinder with one hand and with one hand by pressing the tube out of the cylinder, when the strut spring has obtained the required clamping force, an impact of the nail causing release of the hammer is achieved.

Vid en praktisk utforingsform av uppfinninge.n stravar hammaren genom fjaderkraft att intaga ett i roret indraget lage, men densamma kan medelst ett utifran manuellt paverkbart organ mot verkan av fjaderkraften skjutas ut ur ri5ret, for att bringas i beroring med ett spikhuvud. NOr det senare attraherats till hammaren drages denna jamte spiken av fjaderkraften in i roret, vilket senare styr spiken under islagningen. In a practical embodiment of the invention, the hammer struts by spring force to enter a bearing retracted into the tube, but it can be pushed out of the tube by means of an externally manually operable member against the action of the spring force, to be brought into contact with a nail head. When it is later attracted to the hammer, this smooth nail is pulled by the spring force into the rudder, which later controls the nail during the impact.

Den i apparaten ingaende utlosningsanordningen kan framstallas mycket enkelt och ut gOras av en med kolven svangbart forenad arm eller liknande, som genom fjaderkraft stravar att intaga ett sadant lage, att en med roret samverkande medbringare medtager kolven vid rorets intryckning, men vilken arm, nar slagfjadern uppnalt tillracklig spannkraft, av ett inuti cylindern forefintligt utsprang eller dylikt bibringas sadan lagefOrandring, att armen gar ur ingrepp med medbringaren, varvid slagfjadern frigares och forskjuter kolven, som harvid slar an mot hammaren. The release device included in the apparatus can be manufactured very simply and is made by an arm pivotally connected to the piston or the like, which by spring force strives to assume such a position that a carrier cooperating with the rudder carries the piston when the rudder is depressed, but which arm reaches the strut spring. sufficient clamping force is obtained, from a projection present inside the cylinder or the like is imparted in such a way that the arm disengages from the carrier, whereby the striking spring is released and displaces the piston, which thereby strikes the hammer.

Vi-dare kan medbringaren utgOras av en hylsa, vars e.na mynning stoder mot rorets in mot cylindern vanda ande, under det att hylsans andra mynningsparti till nagon del omgiver kolven, Mir delarna intaga overksamma lagen. Slutligen Or a cylinderns Iran roret vanda ande pagangad en huv eller liknande, mellan vilken senare och kolven slagfjadern Or inspand, varvid huven genom att gangas pa eller av cylindern okar eller minskar slagfjaderns spanning, sa tilt apparaten med latthet kan avpassas for spikning uti olika material. Furthermore, the carrier can be formed by a sleeve, one mouth of which stands against the spirit of the rudder facing the cylinder, while the other mouth portion of the sleeve to some extent surrounds the piston. Finally, the tube of the cylinder Iran is used to engage a hood or the like, between which the latter and the piston the strut spring is clamped, whereby the hood by walking on or off the cylinder increases or decreases the tension of the strut, so that the apparatus can be easily adapted for nailing in different materials. .

En utforingsforrn av uppfinningen askadliggores 0 bifogade ritning, som vista- en langdsektion genom spikningsapparaten. 5 betecknar en cylinder, 1 vars ena Ande Or infort ett For 13, som med en ringformad flans anligger mot insidan av en i cylindern ingangad ringformad mutter 12. Mot rorets 13 flans stoder ena anden av en hylsa 11, i vars ovre andparti nedre andpartiet av en kolv 4 till flagon del ingar. Mot kolvens ovre ande anligger en slagfjader 3, vars andra ande anligger mot en huv 1, genom vars kringvridning i ena eller andra riktningen en Rad eller minskad spanning av fjadern kan ernas. I instant loge lases huven genom aldragning av en lasmutter 2. Uti en urtagning i kolven 4 Or svangbart anbragt en arm 6, som genom inverkan av skruvfjader 8 stravar att intaga sitt 0 ritningen visade liige. 10 betecknar en runt hammaren 9 anbragt skruvfj ader, som stravar att draga in hammaren i roret 13 till sitt 0 ritningen visade lage. An embodiment of the invention is shown in the accompanying drawing, which shows a longitudinal section through the nailing apparatus. 5 denotes a cylinder, 1 one end of which is inserted into a For 13, which with an annular flange abuts against the inside of an annular nut 12 entered in the cylinder. Against the flange of the tube 13 stands one end of a sleeve 11, in the upper end portion of the lower end portion of a piston 4 to the flag parts. Against the upper spirit of the piston abuts a strut spring 3, the other end of which abuts against a hood 1, by means of which rotation in one or the other direction a row or reduced tension of the spring can be obtained. In the instant lodge, the hood is welded by tightening a welding nut 2. In a recess in the piston 4, an arm 6 is pivotally arranged, which, by the action of a coil spring 8, tries to take its position. 10 denotes a helical spring arranged around the hammer 9, which strains to pull the hammer into the tube 13 to its position shown in the drawing.

Yid anvandning fungerar apparaten enligt f olj ande : Medelst det med hammaren forenade, till 2— — hoger a ritningen synliga och fran cylinderns utsida atkomliga manOverorganet forskjutes hammaren 9 mot verkan av fjadern 10 sa langt ut ur roret 13, att hammaren kan attrahera ett spikhuvud. AT fjadern 10 drages darefter hammaren med vidhliftande spik for intagande av islagningslage in till hammarens utgangslage. Harefter pressas roret 13 an mot det yederlag, 'van spiken skall skis in, och samtidigt med att rOret harvid flirskjutes in i cylindern medtager hylsan 11. kolven 4, genom att armens 8 nedre dude stOder mot hylsans 11 ovre mynning. Slagfjadern 3 sammantryckes Yid denna kolvens forskjutning och Mir kolven tillryggalagt en yiss stracka, kommer den a ritningen synliga uti eylindern forefintliga fOrtrangningen slutligen att bringa armen 6 ur ingrepp med hylsan 11. Kolven 4 och slagfjadern 3 frigoras dd och genom fjaderns spanning kommer kolven 4 att bibringa hammaren 9 ett, en islagning ay spiken medforande slag, varvid kolvens riirelse i fjaderns kraftriktning hegransas av ovannamnda fortrangning i cylindern. Nar apparaten avlagsnas fran yederlaget aterintaga delarna sina a ritningen Asada Iligen. In use, the apparatus operates as follows: By means of the hammer connected to the hammer, visible to the right and visible from the outside of the cylinder, the hammer 9 is displaced against the action of the spring 10 so far out of the tube 13 that the hammer can attract a nail head. . AT the spring 10 is then pulled the hammer with adjoining nails for taking in the striking stroke into the starting position of the hammer. Then the tube 13 is pressed against the surface on which the nail is to be skipped, and at the same time as the tube is thereby slid into the cylinder, the sleeve 11 carries the piston 4, by the lower dude of the arm 8 abutting against the upper mouth of the sleeve 11. The strut spring 3 is compressed by this displacement of the piston and Mir the piston is traveled a short distance, the constriction visible in the cylinder will finally bring the arm 6 out of engagement with the sleeve 11. The piston 4 and the strut spring 3 are released and by the tension of the spring 4 impart to the hammer 9 a stroke which results in an impact on the nail, the movement of the piston in the direction of force of the spring being increased by the above-mentioned displacement in the cylinder. When the appliance is removed from the base, reassemble the parts in the drawing Asada Iligen.

Sasom av ovanstaende framgar, ingar i apparaten ett myeket ringa antal delar. Samtliga dessa am o ur fabrikationssynpunkt mycket enkla att framstalla och fungera hell tviingsmassigt. Det sager sig sjalvt att npparaten kan anyandas i vilket lage som heist och IsIagningsriktningen for spiken blir enbart beroende pa cylinderns 5 resp. rorets 13 stunning relativt yederlaget. As can be seen from the above, a very small number of parts are present in the apparatus. All of these are, from a manufacturing point of view, very easy to manufacture and work quite ambiguously. It goes without saying that the device can be used in any position and the direction of insertion of the nail will only depend on the cylinder 5 resp. rudder 13 stunning relative yederlaget.

Flera utforingsformer aro givetvis tankbara inom ramen av uppfinningen och sarskilt torde medbringare- och utlosningsorgan kunna varieras pa en mangfald olika satt, titan att den till grund for uppfinningen liggande iden harfor hehover frangas. Several embodiments are of course conceivable within the scope of the invention, and in particular carriage and release means should be able to be varied in a variety of different ways, provided that the idea underlying the invention has to be abandoned.
