9 Claims.

The present invention relates to running gear units used for baby carriages, strollers, or the like.

It is well known that in prior art devices the body of a baby carriage, stroller or the like is permanently secured to its running gear and thus each vehicle is equipped with its own running gear despite the fact that the running gears used for the different vehicles are about identical.

It is, therefore, one of the objects of the present invention to provide a common running gear on which different units may be easily and exchangeably mounted.

It is another object of the present invention to provide a running gear with means which easily, through a sliding movement, receive a complementary portion of a unit to be exchangeably mounted on the running gear.

It is a further object of the present invention to provide a running gear supporting a unit which may be easily lifted from the gear.

It is still another object of the present invention to provide a running gear equipped with channel members which receive complementary portions secured to different units to bemounted on the running gear.

It is yet another object of the present invention to provide a running gear having a pusher handle and means for exchangeably mounting of different units on said running gear.

It is a further object of the present invention to provide a running gear equipped with channel members receiving complementary portions secured to diflerent units to be mounted on said running gear and to provide releasable means .on

the channel members for locking said complimentary portions on the latter.

With these and other objects in view which will become apparent in the following detailed description, the present invention will be clearly understood in connection with the accompanying drawings, in which:

Figure 1 is a perspective top view of ning gear;

Fig. 2 is an elevational view of the running gear with a baby carriage body;

Fig. 3 is an end view of the arrangement shown in Fig. 2;

Fig. 4 is a fragmentary section along the lines 4-4 of Fig. 2;

Fig. 5 is a fragmentary section of a variation similar to that of Fig. 4;

Fig. 6 is an end view of another embodiment of a running gear with a carriage body, thejlatter partly broken away;

Fig. 7 is a fragmentary section on enlarged scale of the embodiment shown in Fig. 6;

Fig. 8 is an elevational view of the running gear with a chair;

Fig. 9 is an end view of the arrangement shown in Fig. 8;

the run- Fig. 10 is an elevational view of a running gear with a cart; and

Fig. 11 is an end view of the arrangement shown in Fig. 10. v

Referring now to the drawings and particularly to Fig. 1, the running gear i comprises two bars 2 which extend in longitudinal or angular direction which maintain the front axle 3 as ceived by the tubular members I2.

tion.

well as the rear axle 4 in parallel position and which are, preferably, of rectangular cross-sec- Each of the axles 3 and 4 are equipped with extensions 5 which carry the wheels 6. Each bar 2 is bent upwards at its rear end to form a curved portion 1, on the end of which a collapsible pusher handle 8 may be mounted.

Two channel members 9 are secured to the axles .3 and 4, preferably adjacent the bars 2, which members Q are welded or secured by other suitable means to the axles. These members 9 may be used for maintaining the axles 3 and t in parallel position and the bars 2 may be dispensed with. Furthermore, if required, the channel members 9 may be disposed at any predetermined distance above the axles 3 and t by providing suitable supporting and distancing means. Inthe embodiment shown in Fig. 1 the channel'members 9 are of C cross-section, it is to be understood, however, that the channel members d may have any convenient cross-section and may for instance form tubes of any shape, since they are adapted to receive portions of a unit to be carried by the running gear, which portions are of a complementary cross-section to the channel members 9, as will be pointed out later. Thus the channel members 9 may be secured to the unit and the complementary portions on the running gear as indicated in the fragmentary section shown in Fig. 5.

Figs. 2 to 4 show the use of the running gear I for a' baby carriage. Such carriage comprises a running gear I, as described above, which is equipped with the channel members 9. A conventional carriage body 10 having a hood H is equipped with tubular members l2 (Fig. 4) which fit exactly into the channel members 9 and slide easily in and out of the latter.- The tubular members l2 are shown of circular cross-section, though it is to-be understood that they may be of rectangular or other convenient section, as long as they are properly received by the channel members 9, or as long as the latter are re- The tubular members 12 are secured to the carriage body Ill by screws l3 or any other suitable means. In order to prevent the removal of the carriage body I0 from the running gear I unvoluntarily spring bolts I4 may be provided in the channel members 9 which are received by corresponding bores IS in the tubular members [2. It is to be underj 3 stood, that the bars 2 may be entirely omitted plementary channels 9 and move the body until the spring bolts ll snap into corresponding bores ii. In order to remove the carriage body it is merely necessary to lift the spring bolts l4 and slide the body ll out. I

- While the construction in which the unit to be supported by the running gear slides out of the .latter, the embodiment shown in Figs. 6 and '7, which is disclosed in connection with a carriage .body, though any other unit may be provided. does not provide sliding means for connection between the running gear and the supporting unit, but is merely set on the running gear which is secured by its own weight. It is preferable, however, to provide locking means between the unit and the gear, which locking means may easily be opened.

Thus, the arrangement shown in Figs. 6 and '7 comprises a running gear i which is equipped with a pair of members 9, extending in longitudinal direction and secured to the axles 3 and l. The supported unit; which is in the present example a carriage body III, has tubular members l2 secured thereto on the side walls thereof,

which members l2 may rest on the axles 3 and.

I. In order to prevent unvoluntary removal of the unit ID from the running gear one or more spring bolts II are provided in either one .of

the members 9 and I! which project into a bore I! of the other member and thereby lock the unit II) to the running gear I, thoughany other convenient locking means may be provided. By

merely withdrawing thespring bolts H, the unit 3 may be lifted from the gear.

The embodiment shownin Figs. 8 and 9 discloses a combination of the running gear I" with a chair l6 thus forming a, stroller. The chair It is preferably made of tubular material, though any other chair may serve the same purpose. as long as it is equipped with tubes I! which are received by channel members 9' of the running gear I The chair 18', as shown in the draw ings, comprises twd longitudinal tubes II, which may be connected by a cross tube l1 at their rear seat 20' and the back 2| are secured in conends whereas their front ends are bent upwards to vertical tubes l8 the upper end of which is bent rearward to form arm supports I 9'. The

, ventional manner to the tubes l8 and the supports l9, respectively.

by a spring bolt (not shown), when the chair is I of the carriage.

The operation of the stroller is similar to that The bottom tubes l2 of the chair It slide into the complementary channel members 9' of the running ear I until locked to be mounted on the running gear. In order to remove the chair, it is merely necessary to withdraw the spring bolt and then slide easily the tubes I2 of the chair bottom out of the channel members 9', whereupon the chair may be used separately for the child either in connection with a table, a high chair, or as auto child seat. It is clear, however, that the channel members 9' may be provided on the chair and the tubular In order to mount- 10 merely necessary to slide the tubes [2 into com 4 members I! on the running gear I' without changing the operation of the stroller.

A third embodiment of the present invention is shown in Figs. 10 and 11 where a running gear I is combined with a shopping cart 24'. As shown in the drawing the running gear I is equipped with channel members 9 and the shopping cart II is in conventional manner made of wire which forms at its upper end a handle 25. The bottom of the cart 24' may carry small wheels! in order to move the cart around whenremoved' from the running gear I. It is essential, however, to secure tubular members It, preferably,

adjacent the bottom of the cart 24' to the latter.

which are received by the complementary channel members in of the running gear I, though it is possible to reverse this arrangement and to secure the channel members to the cart and the tubular members to the running gear.

The-operation'of this embodiment is similar to that of the two other embodiments. In order to mount the shopping cart on the running gear, it is merely necessary to slide the tubular members ofthe cart into the channels of the running gear until a spring bolt (not shown) which may be provided on each of the channels, snaps into a corresponding bore (not shown) of the tubular members. In order to remove the cart, it is again.

just necessary to withdraw the spring bolts, if any, and slide the tubular members of the cart out of the channel members of the running gear. It should be emphasized that the arrangement shown in Figs. 6 and '7 in connection with a carriagebody may be used in the same manner for a chair, a cart or any other unit, since the three units, namely carriage body, chair and cart are given as examples only and any other unit may be mounted on the running gear by suitable means which permit of easy removal of the unit from the running gear, without requiring tools,

' but by a simple hand operation. Furthermore the longitudinal members, as for instance the channel members or any other guide members,

may extend throughout the entire length of the horizontal leg portions of the chair, or may be of a shorter length, as long as they are or have components which operate as barrier means which prevent lateral movement of the leg portions. In this manner the longitudinal members guide the horizontal leg portions into supported position,

While I have disclosed several embodiments of the presentinvention and particularly three specific units with the running gear, it is to be understood that these embodiments are given by example only without limiting the scope of the present invention, the scope of which is to be determined by the objects and the claims.
