Hand lamp

The invention relates to a hand lamp with a housing for an electric battery, one detachable with the housing connected head part, which has a shell provided with a lens holding ring, a reflector and a lamp holder, a sheathed cable that electrically connects the lamp holder with electrical terminals in the battery housing and that in a Storage position can be wound up and unwound from this position and with a switch with which the contact between the battery terminals and a lamp held in the lamp holder can be established | and is interruptible.

The invention aims to create a hand lamp that allows a lamp unit to be used underground with to use a battery case, in which battery case cells are housed for the supply of electrical energy for the light unit. The lighting unit should

if tool battery housings can be disconnected to connect to a tob battery case to be used remotely. if The light unit is attached to the battery housing, there should be no exposed connecting means of great length which could form an obstacle during the transport of the hand lamp or during its use when the lamp unit is attached to the battery housing.

The hand lamp according to the invention of the type mentioned at the beginning is characterized in that the head part is releasably connected to an attachment rotatable about a bearing pin arranged on an end wall of the battery housing and that the attachment and the end wall together form a chamber in which the cable can be wound up around the axis of the bearing journal and off which the cable can be pulled out by turning the attachment relative to the housing when the head part β β is removed.

The essay can be provided with squats, which with the said Handle together in such a way that the rotation of the handle about the axes of the inwardly directed ends is the axial Withdrawal of inward sins.

So that the invention can be easily understood, an execution example is given below with reference to the accompanying drawings

described. Show it:

Fig. 1 is a side view of a hand lamp according to the invention,

FIG. 2 shows a longitudinal section along line H-II in FIG. 1 and FIG. 3 shows a cross section along line IH-III in FIG. 2.

From the drawing it can be seen that the hand lamp has a head part 1 which is releasably attached to a housing 2 of an electrical Battery is attached and which has a housing 3 on which a lens 4 in a lens holding ring 5, a reflector 6 and a Lamp holder 7 are arranged.

The battery case 2 is designed so that it can accommodate three electrical cells, of which only two in the drawing Cells θ and 9 are shown (see Fig. 2). A sheathed cable 10 (see Fig. 2), which has two insulated wires 11 and 12, connects the lamp holder 7 to battery connections which are formed by terminals 13 and 14 in the housing 2. As Will be described below, the sheathed cable 10 is in a chamber 20 between an attachment 17 for the head part 1 and a End wall 19 of the battery case 2 housed such that

the cable 10 can be pulled out of the chamber 20 when the head part 1 is released and that the cable 10 can be housed again in the chamber 20 before the head part 1 on Attachment 17 is attached. A switch 15 can be operated that it establish contact between the battery terminals 13, 14 and a lamp 16 held in the lamp holder 7 or interrupt.

The head part 1 can be detachably connected to an attachment 17, which attachment is rotatable about a bearing pin 18 which is attached to the End wall 19 of the housing 2 is attached. The attachment 17 forms together with the Absohlußwand 19 a chamber 20 in which the cable 10 is wound around the axis of the journal 18 by rotating the attachment 17 relative to the battery housing 2 and from which it can also be unwound again.

The end wall 19 of the battery housing 2 is an upper contact plate 21 adjacent (see Fig. 3)> the three contact members 22, 23 and 24 has. A lower contact plate 25 (compare Fig. 2) is arranged at the other end of the battery housing 2 and also has three contact members, of which only two members 26 and 27 are shown in the drawing (see Fig. 2). Each of these contact members on the upper 21 and lower contact plate 25 makes electrical contact with a pole of a

of said three battery cells and the contact members on each of said contact plates 21, 25 are connected to one another in such a way that the three battery cells are connected in series. The upper contact plate 21 also carries the two battery connection terminals 13 and 14, where the terminal 14 is connected to a contact member on the upper contact plate 21 and the terminal 14 is connected to the third contact member (not shown) - the lower contact plate 25.

The sheathed cable 10, which at one end with the terminals 13 » is connected, goes from the area of the upper contact plate 21 through an opening 28 in the end wall 19 into the chamber 20, in which it can be wound around the axis of the journal 18. The other, connected to the lamp holder 7 end of the Cable 10 extends from the chamber 20 through a guide opening 29 (see Pig. 1) and enters the housing 3 of the Head part 1 through an opening 30. Inside the head part ™ les 1 are the insulated wires 11, 12 of the cable 10 with a leading to a rare contact 32 on the lamp 16 resilient Contact member 31 (Pig. 2) and a resilient contact member 33 connected, the latter with a base contact 34 on the Lamp 16 can be connected and forms part of switch 15.

The switch 15 is actuated by rotating the lens holding ring 5 relative to the housing 3 of the head part 1. To this end

the lens holder ring 5 is rotatably mounted on the head part housing 3 and connected to the reflector 6 which carries an annular part 35 as a cam 36.

Tabs 37 »38 diametrically opposed to one another extend laterally from the head part housing 3 and can engage in grooves 39 and 40 provided on the attachment 17. The lobes 37 and 38 are retained in these grooves 39 »40 by a handle 41, which handle has inwardly directed ends 42 »43 which extend through the attachment 17 to with the grooves 39» 40 for the purpose of retaining the tabs 37 »38 cooperate in these grooves and which are retractable in the axial direction in order to release the tabs 37» 38 and to allow their removal from said grooves.

In the embodiment shown in the drawings, the files of the attachment adjacent to each of the tabs 37 »38 are 17 provided with cams 44 and 45, which are arranged »that they can interact with the handle 41 in such a way that the rotation of the handle 41 about the axes of the inwardly

ends 42, 43 the axial retraction of these ends 42, has the consequence.

If the head part 1 is removed from the attachment 2, that can Cable 10 can be pulled through the guide opening 29, the housing 2 rotating relative to the attachment 17 until sufficient Cable is pulled out or until the cable is fully extended to allow the head section to be removed from the battery case is usable. After such use, the head section is reattached to the attachment and the cable is in the Chamber 20 wound up again by rotating the housing 2 relative to the attachment 17 until the slack cable in the chamber 20 is stowed away.
